Description

BACKGROUND

Electrical connector systems generally include circuits and components on one or more interconnected circuit boards. Examples of circuit boards in an electrical connector system can include daughter boards, motherboards, backplane boards, midplane boards, or the like. Electrical assemblies can further include one or more electrical connectors that provide an interface between electrical components, and provides electrically conductive paths for electrical communications data signals and/or electrical power so as to place the electrical components in electrical communication with each other.

For instance, a conventional electrical connector system can include an electrical card-edge connector that is electrically connected between a printed circuit board (PCB) and an edge card. The card-edge connector has a mating end that defines a slot that receives an edge of the edge card and a mounting end that mounts onto the PCB. The card-edge connector provides an electrically conductive path between traces proximate to the edge of the edge card and traces on the PCB. Such a configuration may be well suited for an electrical connector system in an enclosure, such as a rack-mount server.

As another example, a conventional electrical connector system can include mezzanine connectors that place a first substrate that can be a printed circuit board (PCB) into electrical communication with a second substrate that can also be a PCB. The electrical connector system can include first and second electrical connectors that mate with one another. The first electrical connector includes a first dielectric connector housing and a first plurality of contacts supported by the first connector housing. The first electrical connector defines a first mounting interface that mounts onto the first substrate, and a first mating interface that mates the second electrical connector. The second electrical connector includes a second dielectric connector housing and a second plurality of contacts supported by the second connector housing. The second electrical connector defines a second mounting interface that mounts onto the second substrate, and a second mating interface that mates the first electrical connector at the first mating interface. When mated, the connectors provide an electrically conductive path between traces carried by the first substrate and traces carried by the second substrate.

DETAILED DESCRIPTION

In electrical connector systems, impedance mismatch between an electrical connector and a complementary electrical component coupled to the electrical connector can lead to signal reflections that adversely affect the performance of the system. Therefore, one consideration when designing an electrical connector is to match the impedance of the electrical connector with the complementary component. This disclosure relates to electrical contact configurations and arrangements that can be used to improve impedance matching in electrical connectors.

Referring to FIGS. 1 to 5, an electrical connector system 10 includes an electrical connector 100, a first complementary electrical component 300, and a second complementary electrical component 400. The first complementary electrical component 300 can be configured as a first substrate, such as a first printed circuit board (PCB). Similarly, the second electrical component 400 can be a second substrate, such as a second printed circuit board. The electrical connector 100 is configured to be placed in electrical communication with each of the first and second electrical components 300 and 400. For instance, the first electrical component 300 can define an edge card that is configured to be received by the electrical connector 100 along a longitudinal direction L so as to mate the electrical connector 100 with the first electrical component. The electrical connector 100 can be mounted to the second electrical component 400. It is thus appreciated that the electrical connector can be configured to electrically couple the first and second complementary electrical components 300 and 400 to one another. Accordingly, the electrical connector 100 provides an electrically conductive path between the first and second electrical components 300 and 400, such as from at least one of the first and second complementary electrical components 300 and 400 to the other of the first and second complementary electrical components 300 and 400.

The electrical connector 100 includes a dielectric or electrically insulative connector housing 102 and a plurality of electrical contacts 195 that are supported by the connector housing 102. For instance, the electrical contacts 195 can be arranged in at least one row that is oriented along a row direction R. In one example, the electrical contacts 195 can be supported by the connector housing 102 in at least first and second rows R₁ and R₂ that are spaced apart from one another along a column direction C so as to define an insertion slot 112 between the first and second rows R₁ and R₂. The rows can be oriented along a lateral direction A that is substantially perpendicular to the longitudinal direction L. The column direction C can be oriented along a direction that is perpendicular to each of the lateral direction A and the longitudinal direction L. For instance, the column direction C can be oriented along a transverse direction T. Each of the at least one row of electrical contacts can include a first plurality of electrical contacts 200 supported by the housing 102, and a second plurality of electrical contacts 200′ supported by the housing 102.

Turning now to FIGS. 6 and 7, and as will be described in more detail below, the first and second electrical contacts 200 and 200′ each have respective mating ends that are configured to mate with the first complementary electrical component 300, and mounting ends that are configured to be mounted to the second complementary electrical component 400. However, the first and second electrical contacts 200 and 200′ can have at least one or both of a different shape and a different size with respect to each other. Unless otherwise indicated, the following description of the first electrical contacts 200 will apply equally to the second electrical contact 200′.

The first electrical contacts 200 can each include a mounting end 202, and a mating end 204 opposite the mounting end 202 along the longitudinal direction L. The mounting end 202 is configured to be mounted onto, for example, the second complementary electrical component 400 along a mounting direction. The mating end 204 is configured to mate with, for example, the first complementary electrical component 300 along a mating direction. In one example, the mating direction and mounting direction can be oriented along the same direction. For instance, the mating direction and mounting direction can be oriented along the longitudinal direction L. Thus, the electrical contact 200 is considered to be a vertical electrical contact. Alternatively, the electrical contact 200 can be configured as a right-angle contact, whereby the mating direction and the mounting direction are oriented substantially perpendicular to each other. For instance, when the electrical contact 200 is configured as a right-angle contact the mating end 204 can be oriented along the longitudinal direction L, and the mounting end 202 can be oriented along the transverse direction T.

The electrical contact 200 includes a contact body 207 that defines first and second edges 206 and 208, and first and second broadsides 210 and 212. The first and second edges 206 and 208 are spaced opposite from one another along the lateral direction A. Thus, the first and second edges 206 and 208 can face away from one another. At least respective portions of the first and second broadsides can be spaced opposite each other along the transverse direction T. Thus, the first and second broadsides 210 and 212 can face away from one another. It should therefore be appreciated that each of the first and second edges 206 and 208 are connected between the first and second broadsides 210 and 212. Similarly, each of the first and second broadsides 210 and 212 are connected between the first and second edges 206 and 208. The edges 206 and 208 and broadsides 210 and 212 can define respective distances along a plane that is oriented normal to the contact body 207. For instance, the edges 206 and 208 can each extend along a first distance from one of the first and second broadsides 210 and 212 to the other of the first and second broadsides 210 and 212 along the plane. The broadsides 210 and 212 can each extend along a second distance from one of the first and second edges 206 and 208 to the other of the first and second edges 206 and 208 along the plane. The second distance can be greater than the first distance. In one example, the first distance can define a thickness of the contact body 207, and the second distance can define a width of the contact body 207. The thickness along at least a portion of the contact body 207 can be oriented along the transverse direction T, and the width along at least a portion of the contact body 207 can be oriented along the lateral direction A.

The electrical contact 200 includes an anchoring region 214 that is configured to secure the electrical contact 200 to the connector housing 102 of the electrical connector 100. The electrical contact 200 further includes a contact beam 216 that extends out with respect to the anchoring region 214. For instance, the contact beam 216 can extend out with respect to the anchoring region 214 along the longitudinal direction L. In one example, the contact beam 216 can extend from the anchoring region 214.

The contact beam 216 has first and second sides 216a and 216b, and first and second faces 216c and 216d. The first and second sides 216a and 216b of the contact beam 216 are defined by the first and second edges 206 and 208, respectively, of the contact body 207. Similarly, the first and second faces 216c and 216d of the contact beam 216 are defined by the first and second broadsides 210 and 212, respectively, of the contact body 207. The contact beam 216 can define a mating portion 217 that is configured to mate with the first complementary electrical component 300, and a stub 219 that extends from the mating portion 217 to the free end 218. The contact beam has a first beam portion that extends along a central axis CA, and a second beam portion that extends from the first beam portion towards the free end 218 of the contact beam 216 along a direction that is angularly offset from the central axis with respect to the lateral direction A.

The anchoring region 214 extends between the mounting end 202 and the contact beam 216. For instance, the anchoring region 214 can extend from the mounting end 202 to the contact beam 216. The anchoring region 214 can define a maximum length L_max,2. Further, the anchoring region 214 can be disposed partially or fully below a midpoint of the electrical contact 200 along the longitudinal direction L. The contact beam 216 extends between a free end 218 of the electrical contact 218 and the anchoring region 214, such as from the free end 218 to the anchoring region 214, and has a maximum length L_max,3. One or more up to all of the maximum lengths of the first electrical contact 200′ can be different than the corresponding one or more up to all of the maximum lengths of the second electrical contact 200′ (FIG. 7) as described in further detail below.

The anchoring region 214 can be substantially planar as it extends from the mounting end 202 to the contact beam 216 along the longitudinal direction L. For instance, the broadsides 210 and 212 can be substantially planar along respective planes that are defined by the longitudinal direction L and the lateral direction A at the anchoring region 214 from the mounting end 212 to the contact beam 216. Similarly, the edges 206 and 208 can be substantially planar along respective planes that are defined by the longitudinal direction L and the transverse direction at the anchoring region 214 from the mounting end 212 to the contact beam 216. Alternatively, the anchoring region 214 can have a bent, such as a curved, shape between the mounting end 202 and the contact beam 216.

The anchoring region 214 can include at least one of first portion, a second portion, and a third portion. The third portion can disposed between the first and second portions, and thus can be considered to be an intermediate portion. The intermediate portion can define a width along the lateral direction A that is less than the width of at least one or both of the first and second portions along the lateral direction A. Thus, the intermediate portion can also be considered a narrowed portion, and one or both of the first and second portions can be considered enlarged portions. In one example, one or both of the first and second portions can extend out from the contact body 207. For instance, at least one of the first and second portions can extend out from one or both of the edges 206 and 208 along the lateral direction A. In one example, the anchoring region 214 can include a first portion 220, an intermediate portion 224, and a second portion 226. The intermediate portion 224 can be disposed between the first and second portions 220 and 226. In one example, the intermediate portion 224 can be defined by one or both of the edges 206 and 208 of the contact body 207.

The first portion 200 can define opposed outermost sides 220a and 220b. The outermost sides 220a and 220b can be spaced from each other along the lateral direction A. The outermost sides 220a and 220b can be outwardly spaced from the respective first and second edges 206 and 208 along the lateral direction A. The first portion 220 can have a width W₁ along the lateral direction A from the first outermost side 220a to the second outermost side 220b, the width W₁ being greater than the width W₂ of the broadsides 210 and 212 from the first edge 206 to the second edge 208. The first portion 220 can extend between the contact beam 216 and the mounting end 202, such as from the contact beam 216 towards the mounting end 202. The first portion 220 can have a substantially rectangular shape in a plane defined by the longitudinal and lateral directions as shown, or can have any other suitable shape in the plane such as a circle, square, or other polygon. Further, the first portion 220 has a maximum length L_max,4. While the outermost sides 220a and 220b of the first portion 220 be spaced outwardly from the respective edges 206 and 208 with respect to the lateral direction A as described above, it should be appreciated that one or both of the outermost sides 220a and 220b can be continuous or in-line with the respective first and second edges 206 and 208 as desired.

The first portion 220 can extend out from at least one of the edges 206 and 208 along the lateral direction A. For instance, the first portion 220 can extend out from both edges 206 and 208 of the contact beam 216. Further portion 220 can be coplanar with the broadsides 210 and 212. In alternative embodiments, the portion 220 can extend out from only one of the first and second edges 206 and 208 along the lateral direction A. For example, one of the outermost sides 220a and 220b of the first portion 220 can be spaced outward from a corresponding one of the first and second edges 206 and 208 with respect to the lateral direction A, and the other of the sides 220a and 220b of the first portion 220 can be flush or aligned with a corresponding one of the first and second edges 206 and 208 of the contact beam 216.

The first portion 220 can define a body 220c and at least one shoulder, such as a first upper shoulder 220d that extends from the body 220c to the contact body 207, and in particular to one of the first and second edges 206 and 208. The first portion 220 can also define a second upper shoulder 220d that extends from the body 220c to the contact body 207 and in particular to the other one of the first and second edges 206 and 208. It should be appreciated that one or both of the first and second upper shoulders 220d can be omitted in some embodiments. Each upper shoulder 220d can extend from the portion 220 to the contact body 207 along a direction having a directional component along the lateral direction A.

The first portion 220 can include at least one retention feature, such as two retention features 222 that are configured to engage the connector housing 102 so as to secure the electrical contact 200 to the connector housing 102. For example, each retention feature 222 can define a barb having a first barb end 222a that is attached to the body 207, such as the body 220c of the first portion 220, in a hinged manner. As will be described below, in alternative embodiments, the retention feature can be included in a portion of the anchoring region, other than the first portion 220. Each retention feature 222 can further include a second, or free, barb end 222b that is opposite the first barb end 222a and is free from attachment to the body 220c of the first portion 220. As shown, the second barb end 222b can be spaced from the first barb end 222a along the longitudinal direction L, and the hinge can be configured to bend about an axis that extends along the lateral direction A so as to offset the second barb end 222b from the first barb end 222a along the transverse direction. Alternatively, the second barb end 222b can be spaced from the first barb end 222a along the lateral direction A, and the hinge can be configured to bend about an axis that extends along the longitudinal direction L so as to offset the second barb end 222b from the first barb end 222a along the transverse direction. Note that, in alternative embodiments, the at least one retention feature 222 can define a feature other than a barb, such as (without limitation) a fixed protrusion, or a recess that receives a protrusion on the connector housing 102, or the at least one retention feature 222 can be omitted altogether.

The intermediate portion 224 can define opposed outermost sides 224a and 224b. The outermost sides 224a and 224b can be spaced from each other along the lateral direction A. In one example, the intermediate portion defines a width W₃ from one of the outermost sides 224a and 224b to the other of the outermost sides 224a and 224b. The width W₃ of the intermediate portion 224 can be less than the corresponding width of one or both of the portions 220 and 226. For instance, the width W₃ of the intermediate portion 224 can be less than the width of the broadsides 210 and 212 from one of the edges 206 and 208 to the other of the edges 206 and 208. Alternatively, the width W₃ of the intermediate portion 224 can be greater than the width of the broadsides 210 and 212. Alternatively still, the outermost sides 224a and 224b can be defined by the first and second edges 206 and 208, respectively. Thus, the width W₃ of the intermediate portion 224 can be substantially equal to the width of the broadsides 210 and 212.

The intermediate portion 224 can extend between the first portion 220 and the mounting end 202 along the longitudinal direction L. For instance, the intermediate portion 224 can extend from the first portion 220 toward the mounting end 202. The intermediate portion 224 can define a maximum length L_max,5 along the longitudinal direction L. The intermediate portion 224 can have a substantially rectangular shape in a plane defined by the longitudinal and lateral directions as shown, or can have any other suitable shape in the plane such as a circle, square, or other polygon. Further, the first outermost side 224a can be linear as it extends from the first portion 220 towards the mounting end 202. Similarly, the second outermost side 224b can be linear as it extends from the first portion 220 towards the mounting end 202. As shown, the intermediate portion 224 of the electrical connector 200 in FIG. 6 can be elongate along the longitudinal direction L as it extends between the first portion 220 and the mounting end 202, such that the maximum length L_max,5 of the intermediate portion 224 is greater than each of the width W₃ of the intermediate portion 224 along the lateral direction and the thickness of the intermediate portion 224 along the transverse direction T. Further, the intermediate portion 224 of the electrical connector 200′ in FIG. 7 can be shortened, such that the maximum length L_max,5 of the intermediate portion 224 is less than or equal to one or more of the width W₃ of the intermediate portion 224 and the thickness of the intermediate portion 224, or can be eliminated altogether.

The first portion 220 can define at least one lower shoulder, such as a first lower shoulder 220e that extends from the body 220c of the first portion 220 to the intermediate portion 224. For instance, the first lower shoulder 220e can extend from one of the outermost sides 220a and 220b to a corresponding one of the outermost sides 224a and 224b. The first portion 220 can also define a second lower shoulder 220e that extends from the body 220c to the intermediate portion 224. For instance, the second lower shoulder 220e can extend the other of the outermost sides 220a and 220b to the corresponding other of the outermost sides 224a and 224b. It should be appreciated that one or both of the first and second lower shoulders 220e can be omitted in some embodiments. Each lower shoulder 220e can extend from the portion 220 to the intermediate portion 224 along a direction having a directional component along the lateral direction A. Further, each lower shoulder 220e can face away from a corresponding upper shoulder 220d.

The second portion 226 can define opposed outermost sides 226a and 226b. The outermost sides 226a and 226b can be spaced from each other along the lateral direction A. The outermost sides 226a and 226b can be outwardly spaced from the respective first and second sides 224a and 224b of the intermediate portion 224 along the lateral direction A. The outermost sides 226a and 226b can also be outwardly spaced from the respective first and second edges 206 and 208 along the lateral direction A. The second portion 226 can have a width W₄ along the lateral direction A from the first outermost side 226a to the second outermost side 226b, the width W₄ being greater than the width W₂ of the broadsides 210 and 212 from the first edge 206 to the second edge 208. The second portion 226 can extend between the contact beam 216 and the mounting end 202, such as from the mounting end 202 towards the contact beam 216. The second portion 226 can have a substantially rectangular shape in a plane defined by the longitudinal and lateral directions as shown, or can have any other suitable shape in the plane such as a circle, square, or other polygon. Further, the second portion 226 has a maximum length L_max,6. While the outermost sides 226a and 226b of the second portion 226 can be spaced outwardly from the respective first and second sides 224a and 224b as described above, it should be appreciated that one or both of the outermost sides 226a and 226b can be continuous or in-line with the respective first and second sides 224a and 224b as desired.

The second portion 226 can extend outward from at least one of the sides 224a and 224b of the intermediate portion 224 along the lateral direction A. For instance, the second portion 226 can extend outward from both of the sides 224a and 224b of the intermediate portion 224. Further, the second portion 226 can be coplanar with the broadsides 210 and 212. In alternative embodiments, the second portion 226 can extend out from only one of the first and second sides 224a and 224b along the lateral direction A. For example, one of the outermost sides 226a and 226b of the second portion 226 can be spaced outward from a corresponding one of the first and second sides 224a and 224b with respect to the lateral direction A, and the other of the sides 226a and 226b of the second portion 226 can be flush or aligned with a corresponding one of the first and second sides 224a and 224b of the intermediate portion.

The second portion 226 can define a body 226c and at least one shoulder, such as a first upper shoulder 226d that extends from the body 226c to the intermediate portion 224, and in particular to one of the first and second sides 224a and 224b of the intermediate portion 224. The second portion 226 can also define a second upper shoulder 226d that extends from the body 226c to the intermediate portion 224, and in particular to the other one of the first and second sides 224a and 224b of the intermediate portion 224. It should be appreciated that one or both of the first and second upper shoulders 226d can be omitted in some embodiments. Each upper shoulder 220d can extend from the portion 226 to the contact body intermediate portion 224 along a direction having a directional component along the lateral direction A. Further, each upper shoulder 226c can face a corresponding lower shoulder 220c of the first portion 220.

The second portion 226 can define at least one lower shoulder, such as a first lower shoulder 226e that extends from the body 226c of the second portion 226 to the mounting tail 234. For instance, the first lower shoulder 226e can extend from one of the outermost sides 226a and 226b to a corresponding side of the mounting tail 234. The second portion 226 can also define a second lower shoulder 226e that extends from the body 226c of the second portion 226 to the mounting tail 234. For instance, the second lower shoulder 226e can extend from the other one of the outermost sides 226a and 226b to a corresponding side of the mounting tail 234. It should be appreciated that one or both of the first and second lower shoulders 226e can be omitted in some embodiments. Each lower shoulder 226e can extend from the portion 226 to the mounting tail 234 along a direction having a directional component along the lateral direction A. Further, each lower shoulder 226e can face away from a corresponding upper shoulder 226d.

The first and second upper shoulders 220b of the first portion 220 and the first and second lower shoulders 226c of the second portion 226 together can provide four locations of mechanical support that retains the electrical contact in the connector housing. Further, the first and second portion 220 and 226 can be spaced from each other along the longitudinal direction L a distance greater than that of conventional electrical contacts. The distance can be measured from the first and second upper shoulders 220b of the first electrical contact 200 of FIG. 6 to the first and second lower shoulders 226c of the first electrical contact 200 of FIG. 6 along the longitudinal direction L. Thus, as will become appreciated from the description below, at least one of the first and second portions of the second electrical contact 200′ (FIG. 7) is configured to reside at a location aligned with the intermediate portion 224 along the lateral direction A. Additionally, the impedance of the electrical contact 200 at the anchoring region 224 is better matched with the impedance at the contact 200 at 90 Ohms with a 20 picosecond rise time, with respect to conventional electrical connectors. Further, as a result of the greater spacing between the first and second portions 220 and 226, the mechanical support provided by the electrical contact 200 of FIG. 6 can be greater than that of the conventional electrical contact.

The second portion 226 can include at least one retention feature, such as two retention features 228 that are configured to engage the housing 102 of the electrical connector 100. For example, each retention feature 228 can define a recess such as a dimple that extends into the body 226a to receive a protrusion of the connector housing 102. Note that, in alternative embodiments, the retention features 228 can define features other than recesses, such as (without limitation) barbs as described above or fixed protrusions, or the retention features 228 can be omitted altogether.

The contact beam 216 can be constructed as a flexible beam having a bent, such as curved, shape that extends from the anchoring region 214 to a free end 218 of the electrical contact 200. Bent structures as described herein refer to bent shapes that can be fabricated, for instance, by bending the end or by stamping a bent shape, or by any other suitable manufacturing process. The first broadside 210 at the contact beam 216 is configured to wipe against the first complementary electrical component 300 as the component is mated with the contact beam 216 along the longitudinal direction L. Further, the contact beam 216 is configured to contact the first complementary electrical component 300 so as to apply a force to a surface of the complementary electrical component 300 along the transverse direction T.

The contact beam 216 can include at least a first bend region 230 between the anchoring region 214 and the mating end 204. The first bend region 230 can curve towards a first direction that extends from the second broadside 212 toward the first broadside 210 as the contact beam 216 extends away from the anchoring region 214 along the longitudinal direction L. The contact beam 216 can further include at least a second bend region 232 that is between the first bend region 230 and the mating end 204. The second bend region 232 can curve towards a second direction, opposite the first direction, that extends from the first broadside 210 toward the second broadside 212 as the contact beam 216 extends away from the first bend region 230 along the longitudinal direction L. In alternative embodiments, the curvature of the contact beam 216 can vary from that shown. For example, the contact beam 216 can include as few as one bend region, or greater than two bend regions.

Referring again to FIG. 6, at the contact beam 216, at least one of the first and second edges 206 and 208 can taper toward the other of the first and second edges 206 and 208 as the contact body extends along a direction from the anchoring region 214 toward the mating portion 217. For example, the first edge 206 can taper towards the second edge 208 as the first edge 206 extends from the anchoring region 214 to at least the second bend region 232 or the free end 218. Similarly, the second edge 208 can taper toward the first edge 206 as the second edge 206 extends from the anchoring region 214 to at least the second bend region 232 or the free end 218. Alternatively, one or both of the first and second edges can extend along the longitudinal direction L as the contact body 207 extends from the anchoring region 214 to at least the second bend region 232 or the free end 218. For instance, the first and second edges 206 and 208 can be parallel with each other as the contact body 207 extends from the anchoring region 214 to at least the second bend region 232 or the free end 218. As another example, the second edge 208 can taper towards the first edge 206 as the second edge 208 extends from the anchoring region 214 to at least the second bend region 232 or the free end 218, while the first edge 206 can extend along the longitudinal direction L as the first edge 206 extends from the anchoring region 214 to at least the second bend region 232 or the free end 218. As yet another example, the first and second edges 206 and 208 can taper towards each other as they extend from the anchoring region 214 to at least the second bend region 232 or the free end 218. Alternatively, the first and second edges 206 and 208 can be parallel to one another along at least a portion up to an entirety of the length of the contact beam 216.

Referring to FIG. 9, the anchoring region 214 can define a central axis CA that extends in the longitudinal direction between the first and second broadsides 210 and 212. The second bend region 232 can extend at least partially on a first side of the central axis CA with respect to the transverse direction T, the first side being spaced from the central axis CA along a direction that is opposite the second broadside 212. Further, the free end 218 can be positioned on a second side of the central axis CA with respect to the transverse direction T, the second side being spaced from the central axis CA along a direction that is opposite the first broadside 210.

Referring back to FIGS. 6 and 7, the mounting end 202 can include a mounting tail 234 that extends away from the anchoring region 214. For example, the mounting tail 234 can define a surface-mount tail as shown that is bent, or otherwise curved, outward from the anchoring region 214 along the transverse direction T, such as along a direction that extends from the first broadside 210 towards the second broadside 212. Thus, the mounting tail 234 can be disposed on the same side of the central axis CA as the free end 218 with respect to the transverse direction T as shown in FIG. 10. Alternatively, the mounting tail 234 can extend on the opposite side of the central axis CA as the free end 218. The mounting tail 234 defines a terminal end 236 of the electrical contact 200. The terminal end 236 can be configured as a mounting surface that mounts onto, such as abuts, an electrical contact of the second complementary electrical component 400. The mounting surface can substantially face the longitudinal direction L, such as in a direction away from the free end 218 of the electrical contact. Thus, the mounting surface can be configured to mount onto a complementary electrical component that lies in a plane that is substantially perpendicular to the longitudinal direction L. In alternative embodiments, the mounting tail 234 can be configured as a differently-configured surface-mount tail, as a press-fit tail, as a fusible element such as a solder ball, or combinations thereof.

The electrical contact 200 defines maximum length L_max,1 along the longitudinal direction L from the free end 218 to the terminal end 236. The electrical contact 200 further defines a maximum width W_max,1 along the lateral direction A. The maximum width W_max,1 can be equal to at least one of the width W₁ of the first portion 220 and the width W₄ of the second portion 226, such as a larger of the widths W₁ and W₄. Alternatively, the maximum width W_max,1 can be equal to both the width W₁ of the first portion 220 and the width W₄ of the second portion 226 when the widths W₁ and W₄ are equal. The contact body 207 yet further defines a maximum thickness T_max along the transverse direction T from one of the opposed broadsides 210 and 212 to the other. The maximum length L_max,1 of the electrical contact 200 is greater than both the maximum width W_max,1 and the maximum thickness T_max. Further, the maximum width W_max,1 of the electrical contact 200 can be greater than the maximum thickness T_max. Thus, the electrical contact 200 can be said to be elongate along the longitudinal direction L.

Now the dimensions of the first and second electrical contacts 200 and 200′ will be compared. The first electrical contact 200 has a maximum length L_max,1 from the mounting tail 234 to the free end 218 that is greater than a maximum length L_max,1 of the second electrical contact 200′ from the mounting tail 234 to the free end 218. The difference in the maximum lengths L_max,1 can be attributed at least in part to a difference in the lengths L_max,2 of the anchoring regions 214 of the first and second electrical contacts 200 and 200′. As shown, the maximum length L_max,2 of the anchoring region 214 of the first electrical contact 200 can be greater than the maximum length L_max,2 of the anchoring region 214 of the first electrical contact 200′. Further, the maximum length L_max,5 of the intermediate portion 224 of the first electrical contact 200 can be greater than the maximum length L_max,5 of the intermediate portion 224 of the second electrical contact 200′. Yet further, the maximum lengths L_max,4 of the first portions 220 of the first and second electrical contacts 200 and 200′ can be equal, the maximum lengths L_max,6 of the second portions 226 of the first and second electrical contacts 200 and 200′ can be equal, the maximum lengths of the mounting tails 234 of the first and second electrical contacts 200 and 200′ can be equal, and the maximum lengths L_max,3 of the contact beams 216 of the first and second electrical contacts 200′ can be equal. It is noted that, in alternative embodiments, one or more of these lengths may vary from the first electrical contact 200 to the second electrical contact 200′.

The combined maximum lengths L_max,6 and L_max,5 of the second portion 226 and the intermediate portion 224 of the first electrical contact 200 can be greater than the maximum length L_max,2 of the anchoring region 214 of the second electrical contact 200′. Consequently, as shown in FIG. 8, when the first and second electrical contacts 200 and 200′ are aligned next to one another such that the mounting ends 202 are aligned along the lateral direction A, the first portion 220 of the second electrical contact 200′ can be aligned between the first and second portions 220 and 226 of the first electrical contact 200 with respect to the longitudinal direction L.

The maximum width W_max of the first electrical contact 200 can be greater than, less than, or equal to the maximum width W_max of the second electrical contact 200′, and the maximum thickness T_max of the first electrical contact 200 can be greater than, less than, or equal to the maximum thickness T_max of the second electrical contact 200′. Moreover, in alternative embodiments, one or more of the maximum length L_max,4 of the first portion 220 of the first electrical contact 200, the maximum length L_max,6 of the second portion 226 of the first electrical contact 200, and the maximum length L_max,3 of the contact beam 216 of the first electrical contact 200 can be different from the corresponding lengths of the second electrical contact 200′.

Without being bound by theory, it is believed that anchoring regions of electrical contacts having larger surface areas can suffer from greater drops in impedance than anchoring regions with smaller surfaces areas. However, retention of electrical contacts within connector housings can be weaker for electrical contacts having smaller anchoring regions than for electrical contacts having larger anchoring regions. Contact 200 of FIG. 6 balances these competing concerns (i.e., impedance vs. retention) by (i) reducing the surface area of the anchoring region 214 at the intermediate portion 224 to reduce the impedance drop at the anchoring region 214 and (ii) elongating the anchoring region 214 so as to space the corners 220d further from the corners 220e to increase contact retention. As a result, contact 200 can have an improved impedance profile over a comparable contact having an anchoring region with larger surface area, where the impedance of the contact 200 at the anchoring region 214 does not drop as significantly as the impedance of the comparable contact at its anchoring region.

In at least some embodiments, the dimensions of the electrical contact 200 of FIG. 6 can be as follows: the length L_max,1 can be between approximately 4 mm and approximately 15 mm, the length L_max,2 can be between approximately 1 mm and approximately 6 mm, the length L_max,3 can be between approximately 2 mm and approximately 10 mm, the length L_max,4 can be between approximately 0.3 mm and approximately 2 mm, the length L_max,5 can be between approximately 0.4 mm and 4 mm, the length L_max,6 can be between approximately 0.2 mm and approximately 2 mm, the width W_max,1 can be between approximately 0.3 mm and approximately 0.9 mm, the width W₁ can be between approximately 0.3 mm and approximately 0.9 mm, the width W₂ can be between approximately 0.2 mm and approximately 0.5 mm, the width W₃ can be between approximately 0.2 mm and approximately 0.5 mm, and the thickness T_max can be between approximately 0.125 mm and approximately 0.225 mm.

In at least some embodiments of the electrical contact 200 of FIG. 6, the ratio of length L_max,2 to L_max,1 can be between approximately 1:5 and approximately 2:5, the ratio of L_max,3 to L_max,1 can be between approximately 3:5 and approximately 4:5, and the ratio of L_max,5 to L_max,1 can be between approximately 1:15 and 1:5.

In at least some embodiments, the dimensions of the electrical contact 200′ of FIG. 7 can be as follows: the length L_max,1 can be between approximately 4 mm and approximately 12 mm, the length L_max,2 can be between approximately 1 mm and approximately 4.5 mm, the length L_max,3 can be between approximately 2 mm and approximately 10 mm, the length L_max,4 can be between approximately 0.3 mm and approximately 2 mm, the length L_max,5 can be between approximately 0 mm and 2 mm, the length L_max,6 can be between approximately 0.2 mm and approximately 2 mm, the width W_max,1 can be between approximately 0.3 mm and approximately 0.9 mm, the width W₁ can be between approximately 0.3 mm and approximately 0.9 mm, the width W₂ can be between approximately 0.2 mm and approximately 0.5 mm, the width W₃ can be between approximately 0.2 mm and approximately 0.5 mm, and the thickness T_max can be between approximately 0.125 mm and approximately 0.225 mm.

In at least some embodiments of the electrical contact 200′ of FIG. 7, the ratio of length L_max,2 to L_max,1 can be between approximately 1:10 and approximately 3:10, the ratio of L_max,3 to L_max,1 can be between approximately 3:5 and approximately 4:5, and the ratio of L_max,5 to L_max,1 can be between approximately 0 and 1:4.

Turning now to FIGS. 6 to 8, embodiments of the present disclosure can include a kit having at least a first electrical contact 200(a), which is configured as discussed above in relation to FIG. 6, and at least a second electrical contact 200′, which is configured as discussed above in relation to FIG. 7. As shown, the first and second electrical contacts 200(a) and 200′ can be arranged edge-to-edge such that one of the first and second edges 206 and 208 of the first electrical contact 200(a) faces the other of the first and second edges 206 and 208 of the second electrical contact 200′. Further, the first and second electrical contacts 200(a) and 200′ can be arranged such that the mounting ends 202 of the first and second electrical contacts 200(a) and 200′ are aligned along the lateral direction A. Thus, the second portions 226 of the first and second electrical contacts 200(a) and 200′ can be aligned along the lateral direction A. In other words, the second portions 226 of each of the first and second electrical contacts 200(a) and 200′ can have a center, and the centers can be aligned along a third line that extends substantially along the lateral direction A.

In this arrangement, the first portion 220 of the second electrical contact 200′ is aligned with the anchoring region 214 of the first electrical contact 200(a) along the lateral direction A at a location between the first portion 220 of the first electrical contact 200(a) and the mounting end 202 of the first electrical contact 200(a). For example, the first portions 220 of the first and second electrical contacts 200(a) and 200′ can have a center, and the centers can be offset from one another with respect to the longitudinal direction A. In other words, the location can be between the first and second portions 220 and 226 such that the first portion 220 of the second electrical contact 200′ is aligned with the intermediate portion 224 of the first electrical contact 200(a) along the lateral direction A. In at least some embodiments, the first portion 220 of the second electrical contact 200′ can be fully aligned with the intermediate portions 224 of the first electrical contact 200(a) along the lateral direction A. For example, the outer-most ends of the first portion 220 of the second electrical contact 200′ can be fully contained within an area that is aligned fully between the inner-most ends of the first and second portions 220 and 226 of the first electrical contact 200(a) along the lateral direction A. Additionally, the free end 218 of the first electrical contact 200(a) can extend beyond the free end 218 of the second electrical contact 200′ along the longitudinal direction L.

The first electrical contact 200(a) can have a maximum length L_max,1 along the longitudinal direction L from the mounting end 202 of the first electrical contact 200(a) to the mating end 204 of the first electrical contact 200(a) that is greater than a maximum length L_max,1 of the second electrical contact 200′ along the longitudinal direction L from the mounting end 202 of the second electrical contact 200′ to the mating end 204 of the second electrical contact 200′. Further, the anchoring region 214 of the first electrical contact 200(a) can have a maximum length L_max,2 that is greater than a maximum length L_max,2 of the anchoring region 214 of the second electrical contact 200′. Yet further, the intermediate portion 224 of the first electrical contact 200(a) can have a maximum length L_max,5 that is greater than a maximum length L_max,5 of the intermediate portion 224 of the second electrical contact 200′. Yet still further, the contact beam 216 of the first electrical contact 200(a) can have a maximum length L_max,3 that is substantially equal to a maximum length L_max,3 of the contact beam 216 of the second electrical contact 200′.

The kit can further include a third electrical contact 200(b), which is configured as discussed above in relation to FIG. 6. The second portions 226 of the first and third electrical contacts 200(a) and 200(b) can be aligned along the lateral direction A. In other words, the second portions 226 of each of the first and third electrical contacts 200(a) and 200(b) can have a center, and the centers can be aligned along a first line that extends substantially along the lateral direction A. The first portion 220 of the second electrical contact 200′ can be aligned with the anchoring region 214 of the third electrical contact 200(b) along the lateral direction A at a location between the first portion 220 of the third electrical contact 200(b) and the mounting end 202 of the third electrical contact 200(b), when the mounting ends 202 of the second and third electrical contacts 200′ and 200(b) are aligned along the lateral direction A. For example, the first portions 220 of the second and third electrical contacts 200′ and 200(b) can have a center, and the centers can be offset from one another with respect to the longitudinal direction A. In other words, the location can be between the first and second portions 220 and 226 of the third electrical contact 200(b) such that the first portion 220 of the second electrical contact 200′ is aligned with the intermediate portion 224 of the third electrical contact 220(b) along the lateral direction A. In at least some embodiments, the first portion 220 of the second electrical contact 200′ can be fully aligned with the intermediate portions 224 of the third electrical contact 200(b) along the lateral direction A. For example, the outer-most ends of the first portion 220 of the second electrical contact 200′ can be fully contained within an area that is aligned fully between the inner-most ends of the first and second portions 220 and 226 of the third electrical contact 200(b) along the lateral direction A. Additionally, the free end 218 of the third electrical contact 220(b) can extend beyond the free end 218 of the second electrical contact 200′ along the longitudinal direction L.

The third electrical contact 200(b) can have a maximum length L_max,1 along the longitudinal direction L from the mounting end 202 of the third electrical contact 200(b) to the mating end 204 of the third electrical contact 200(b) that is greater than a maximum length L_max,1 of the second electrical contact 200′ along the longitudinal direction L from the mounting end 202 of the second electrical contact 200′ to the mating end 204 of the second electrical contact 200′. Further, the anchoring region 214 of the third electrical contact 200(b) can have a maximum length L_max,2 that is greater than a maximum length L_max,2 of the anchoring region 214 of the second electrical contact 200′. Yet further, the intermediate portion 224 of the third electrical contact 200(b) can have a maximum length L_max,5 that is greater than a maximum length L_max,5 of the intermediate portion 224 of the second electrical contact 200′. Yet still further, the contact beam 216 of the third electrical contact 200(b) can have a maximum length L_max,3 that is substantially equal to a maximum length L_max,3 of the contact beam 216 of the second electrical contact 200′. It is noted that kits of the present disclosure can have more than three electrical contacts, such as more than two instances of the electrical contact 200 in FIG. 7, and/or more than one instance of the electrical contact 200′ of FIG. 7.

The kit can yet further have a fourth electrical contact 200′, which is configured as discussed above in relation to FIG. 7. The first and third electrical contacts 200(a) and 200(b) can be between the second and fourth electrical contacts 200′. When supported by a connector housing, the center points of the first portions 220 of the first and third electrical contacts 200(a) and 200(b) can be aligned along a first line that extends substantially along the lateral direction A. Further, the center points of the first portions 220 of the second and fourth electrical contacts 200′ can be aligned along a second line that extends substantially along the lateral direction A. The second line can be offset from the first line along the longitudinal direction L. For example, the second line can be spaced close to the mounting ends than the first line. Further, the second line can be substantially parallel to the first line. Similarly, the second portions 226 of the first to fourth electrical contacts can each have a center, and the centers of the second portions 226 of the first to fourth electrical contacts can be aligned along a third line that extends along the lateral direction A. The third line can be offset from one or both of the first and second lines along the longitudinal direction L. For example, the second line can be spaced between the first and third lines with respect to the longitudinal direction L. Further, the third line can be substantially parallel to one or both of the first and second lines.

The second portion 226 of each one of the first, second, third, and fourth contacts 200(a), 200′, 200(b), and 200′ can be considered the outer-most enlarged portion of the contact with respect to its mounting end 202. Thus, the anchoring region of the first contact 200(a) has an outer-most enlarged portion 226 that is closest to the mounting end 202 of the first contact 200(a), the anchoring region of the second contact 200′ has an outer-most enlarged portion 226 that is closest to the mounting end 202 of the second contact 200′, the anchoring region of the third contact 200(b) has an outer-most enlarged portion 226 that is closest to the mounting end 202 of the third contact 200(b), and the anchoring region of the fourth contact 200′ has an outer-most enlarged portion 226 that is closest to the mounting end 202 of the fourth contact 200′. The outer-most enlarged portions 226 of the first to fourth contacts can be aligned with one another along the lateral direction A. All other enlarged portions of the anchoring region of the first and third contact 200(a) and 200(b) can be out of alignment with all other enlarged portions of the anchoring region of the second and fourth contacts 200′. In other words, no other enlarged portion of the first and third contact 200(a) 200(b) is aligned with an enlarged portion of the second or fourth contact 200′.

Referring now to the arrangement of contacts of the electrical connector 100, and with reference to FIG. 5 and FIGS. 8 to 10, the connector housing 102 supports a first plurality of electrical contacts 200 and a second plurality of electrical contacts 200′ in each row of the at least one row of contacts. The electrical contacts 200 of the first plurality are each configured as discussed above in relation to FIG. 6, and the electrical contacts 200′ of the second plurality are each configured as discussed above in relation to FIG. 7. The first and second pluralities of the contacts can be spaced along the row direction R such that the edges 206 and 208 of adjacent contacts along the row direction R face one another. Thus, the contacts can be arranged edge-to-edge along the row direction R. Four instances of the electrical contact 200 and three instances of the electrical contacts 200′ are shown. However, embodiments of the present disclosure can include as few as one instance of each of the first and second electrical contact 200 and 200′, or more than four instances of the electrical contact 200 and more than three instances of the electrical contacts 200′.

The electrical contacts 200 of the first plurality can be arranged in pairs 502 such that the individual contacts 200 of each of the pairs 502 are adjacent one another and spaced from one another along a row direction R, which in this embodiment is aligned with the lateral direction A and is perpendicular to both the longitudinal direction L and transverse direction T. The individual contacts 200 of each of the pairs 502 can be immediately adjacent one another without any other electrical contact therebetween. The pairs 502 of the electrical contacts 200 can be arranged such that at least one of the electrical contacts 200′ of the second plurality is disposed between adjacent pairs 502 of the electrical contacts 200 along the row direction R. The adjacent pairs 502 of the electrical contacts 200 can be immediately adjacent one another without any other pair 502 of the electrical contacts 200 therebetween. Further, two electrical contacts 200′ can be spaced from one another along the lateral direction A with only a single pair of electrical contacts 200 therebetween. Thus, the electrical contacts can be arranged along the row direction in the following pattern: electrical contact 200′ of the second plurality-electrical contact 200 of the first plurality-electrical contact 200 of the first plurality-electrical contact 200′ of the second plurality-electrical contact 200 of the first plurality-electrical contact 200 of the first plurality, and so on.

The first portion 220 of each electrical contact 200 and 200′ can have a center point. When supported by the connector housing 102, the center points of the first portions 220 of the electrical contacts 200 can be aligned along a first line that extends substantially along the lateral direction A. Further, the center points of the first portions 220 of the electrical contacts 200′ can be aligned along a second line that extends substantially along the lateral direction A. The second line can be offset from the first line along the longitudinal direction L. For example, the second line can be spaced closer to the mounting ends than the first line with respect to the longitudinal direction L. Further, the second line can be substantially parallel to the first line. Similarly, the second portions 226 of the first to fourth electrical contacts can each have a center, and the centers of the second portions 226 of the first to fourth electrical contacts can be aligned along a third line that extends along the lateral direction A. The third line can be offset from one or both of the first and second lines along the longitudinal direction L. For example, the second line can be spaced between the first and third lines with respect to the longitudinal direction L. Further, the third line can be substantially parallel to one or both of the first and second lines.

When supported by the connector housing 102, the first portion 220 of each of the electrical contacts 200′ of the second plurality can be aligned with the anchoring region 214 of each adjacent one of the electrical contacts 200 of the first plurality along the lateral direction A at a location between the first portion 220 of the adjacent electrical contact 200 and the mounting end 202 of the adjacent electrical contact 200. For example, the location can be between the first and second portions 220 and 226 of the adjacent electrical contact 200 such that the first portion 220 of the electrical contact 200 is aligned with the intermediate portion 224 of the adjacent electrical contact 200 along the lateral direction A. In at least some embodiments, the first portions 220 of the electrical contacts 200′ can be fully aligned with the intermediate portions 224 of the electrical contacts 200 along the lateral direction A. For example, the outer-most ends of the first portions 220 of the electrical contacts 200′ can be fully contained within an area that is aligned fully between the inner-most ends of the first and second portions 220 and 226 of each of the electrical contacts 200 along the lateral direction A. Additionally, the free end 218 of each electrical contact 200 extends beyond the free end 218 of each adjacent one of the electrical contacts 200′ along the longitudinal direction L.

With continuing reference to FIG. 8, the second portion 226 of each one of contacts 200 and 200′ of the first and second pluralities can be considered the outer-most enlarged portion of the contact with respect to its mounting end 202. Thus, the anchoring region of each contact 200 of the first plurality has an outer-most enlarged portion 226 that is closest to the mounting end 202 of the contact 200, and the anchoring region of each contact 200′ of the second plurality has an outer-most enlarged portion 226 that is closest to the mounting end 202 of the contact 200′. The outer-most enlarged portions 226 of the contacts 200 and 200′ of the first and second pluralities can be aligned with one another along the lateral direction A. For example, each enlarged portion 226 can have a center, and the centers of the enlarged portions 226 of the electrical contacts 200 and 200′ can be aligned along a third line that extends along the lateral direction A. The third line can be offset from the first and second lines along the longitudinal direction L. For example, the second line can be between the first and third lines with respect to the longitudinal direction L. Further, the third line can be substantially parallel to one or both of the first and second lines.

All other enlarged portions of the anchoring regions of the contacts 200 of the first plurality can be out of alignment with all other enlarged portions of the anchoring regions of the contacts 200′ of the second plurality with respect to the lateral direction A. Each electrical contact 200 can have a maximum length L_max,1 along the longitudinal direction L from its mounting end 202 to its mating end 204 that is greater than a maximum length L_max,1 of an adjacent one of the electrical contacts 200′ along the longitudinal direction L from the mounting end 202 of the adjacent electrical contact 200′ to the mating end 204 of the adjacent electrical contact 200′. Further, the anchoring region 214 of each electrical contact 200 can have a maximum length L_max,2 that is greater than a maximum length L_max,2 of the anchoring region 214 of an adjacent one of the electrical contacts 200′. Yet further, the intermediate portion 224 of each electrical contact 200 can have a maximum length L_max,5 that is greater than a maximum length L_max,5 of the intermediate portion 224 of an adjacent one of the electrical contacts 200′. Yet still further, the contact beam 216 of each electrical contact 200 can have a maximum length L_max,3 that is substantially equal to a maximum length L_max,3 of the contact beam 216 of an adjacent one of the electrical contacts 200′.

Referring more specifically to FIG. 8, each pair 502 of the electrical contacts 200 includes a first electrical contact 200a and a second electrical contact 200b. At least a portion of the outer edges 206 and 208, respectively, of the first and second electrical contacts 200a and 200b can be tapered towards one another as they extend toward their respective free ends 218. Further, the inner edges 208 and 206, respectively, of the first and second electrical contacts 200a and 200b can be aligned with the longitudinal direction L so as to not be tapered towards one another as they extend toward their respective free ends 218. In other words, at least a portion of the inner edges 208 and 206, respectively, of the first and second electrical contacts 200a and 200b can be substantially parallel to one another, rather than taper away from one another. As a result, the spacing between the inner edges 208 and 206, respectively, of the first and second electrical contacts 200a and 200b can be closer to one another than in comparable electrical connectors where the inner surfaces taper away from one another. Without being bound by theory, it is believed that the closer spacing can result in the contact beams 216 of the first and second electrical contacts 200a and 200b being more tightly coupled together than comparable contacts that taper away from one another. Further, it is believed that the tighter coupling can increase the power flow of the signals in between the first and second electrical contacts 200a and 200b along the longitudinal direction L, can improve impedance control, and can reduce crosstalk.

In at least some embodiments, the stubs 219 of the electrical contacts 200 of each pair 502 flare away from one another as the stubs 219 extend toward the free end 218. Further, the stub 219 of a first electrical contact 200 of a pair 502 can extend at an acute angle relative to the stub 219 of a second electrical contact 200 of the pair. Flaring the stubs 219 of two contacts 200 of a pair 502 away from one another can reduce capacitive coupling between the two contacts 200, resulting in less interference between the signals conducted over the two contacts 200 than if the stubs 219 were parallel to one another. Moreover, arranging the shorter contacts 200′ adjacent the pairs 502 of contacts 200 can result in lower capacitive coupling between the flared stubs 219 and the adjacent contacts than would occur if the adjacent contacts were longer.

Each individual instance of the first electrical contact 200 can define a signal contact, and each individual instance of the second electrical contact 200′ can define a ground contact. Further, each pair 502 of the signal contacts 200 can define a differential signal pair. Thus, the electrical contacts in the arrangement of FIGS. 8 and 10 can define the following pattern along the row direction R from left to right: ground-signal-signal-ground-signal signal, which can be repeated. Thus, in such arrangement, the signal contacts 200 can each have a maximum length L_max,1 along the longitudinal direction L that is greater than the maximum length L_max,1 of each of the ground contacts 200′ along the longitudinal direction L.

Without being bound by theory, it is believed that designating the shortened contacts 200′ in the rows of FIGS. 5 and 8 to 10 as ground contacts can shift common mode resonance of the contacts 200′ out in frequency to improve crosstalk. Further, it is believed that interspersing the shortened ground contacts 200′ with the elongated signal contacts 200 as shown in FIGS. 5 and 8 to 10 can place the beam profiles of the shortened ground contacts 200′ out of plane with those of the elongated signal contacts 200 so to allow signal pair cancellation on ground beam, which can result in reduced cross coupling or crosstalk. Moreover, it is believed that interspersing the shortened ground contacts 200′ with the elongated signal contacts 200 can reduce capacitance of the tips of the elongated signal contacts 200. This in turn allows the tips of the elongated signal contacts 200 to be lengthened for a mechanical advantage where longer tips can be more robust to avoid stub damage when the electrical connector 100 is mated with the first complementary component 300. Each of the aforementioned characteristics enables the connector 100 to operate at faster speeds than comparable prior art connectors, such as speeds up to or exceeding 40 Gigabytes/second.

In alternative embodiments, the contacts 200 and 200′ can define an open pin field. For instance, the plurality of first electrical contacts 200 can define both signal contacts and ground contacts and the plurality of second electrical contacts 200′ can define both signal contacts and ground contacts. At least one of the first electrical contacts 200 can define a signal contact, at least one other of the first electrical contacts 200 can define a ground contact, at least one of the second electrical contacts 200′ can define a signal contact, and at least one other of the second electrical contacts 200′ can define a ground contact. Thus, the contacts can define grounds and signals in any desired pattern along the row direction R. For instance, the electrical contacts in the arrangement of FIGS. 8 and 10 can define the following pattern along the row direction R from left to right: ground-signal-ground-signal-ground-signal, which can be repeated.

In further alternative embodiments, the electrical contacts 200 and 200′ of the first and second pluralities can be arranged along the row direction in a different pattern, such as (without limitation): electrical contact 200′ of the second plurality-electrical contact 200′ of the second plurality-electrical contact 200 of the first plurality-electrical contact 200 of the first plurality-electrical contact 200′ of the second plurality-electrical contact 200′ of the second plurality-electrical contact 200 of the first plurality-electrical contact 200 of the first plurality, and so on. Moreover, in such an arrangement, the electrical contacts can define the following pattern along the row direction R from left to right: ground-ground-signal-signal-ground-ground-signal-signal, which can be repeated. Referring back to the connector 100 in FIGS. 1 to 4, the connector housing 102 has a mounting end 104 and a mating end 106 that are spaced from one another along a select direction D, which in this embodiment is aligned with the longitudinal direction L of the electrical contacts. The first and second pluralities of contacts 200 and 200′ are supported by the housing 102 such that the mounting ends 202 of the contacts are disposed at the mounting end 104 of the housing 102 and the mating ends 204 of the contacts are disposed at the mating end 106 of the housing. Further, first and second pluralities of contacts 200 and 200′ can be bottom loaded into the connector housing 102 through the mounting end 104, can be injection molded or stitched into the connector housing 102, or loaded into the connector housing 102 in any other suitable manner.

The electrical connector 100 is a vertical electrical connector, wherein the mating end 106 is configured to mate with the first complementary electrical component 300 along a mating direction M_A that is aligned with the select direction D, and the mounting end 104 is configured to mount to the second complementary electrical component 400 along a mounting direction M_O that is also aligned with the select direction D. Thus, in FIGS. 1 to 5, the mating direction M_A and the mounting direction M_O are both aligned with (i.e., parallel to) the select direction D.

In alternative embodiments, the electrical connector can be a right-angle electrical connector, where the mating end 106 is configured to mate with the first complementary electrical component 300 along a mating direction M_A, and the mounting end 104 is configured to mount to the second complementary electrical component 400 along a mounting direction M_O, perpendicular to the mating direction M_A. In such embodiments, the mounting direction M_O can be aligned with the select direction D, and the mating direction M_A can be perpendicular to the select direction D.

The connector housing 102 has first and second sidewalls 108 and 110 that extend from the mating end 106 to the mounting end 104 along the select direction D. The first and second sidewalls 108 and 110 are spaced from one another along the column direction C so as to define an insertion slot 112 therebetween that is sized and configured to receive the first complementary electrical component 300. The insertion slot 112 defines a plane that extends along the select direction D and the row direction R between the first and second rows R₁ and R₂. The connector housing 102 can also include first and second endwalls 114 and 116 that are spaced from one another along the row direction R. The first and second endwalls 114 and 116 can extend from the mating end 106 to the mounting end 104 along the select direction D and from the first sidewall 108 to the second sidewall 110.

The first sidewall 108 includes a first internal surface 108a, and a first external surface 108b spaced opposite from the first internal surface 108a along the column direction C. Similarly, the second sidewall 110 includes a second internal surface 110a, and a second external surface 110b spaced opposite from the second internal surface 110a along the column direction C. The first and second internal surfaces 108a and 110a can face one another along the column direction C, and the first and second external surfaces 108b and 110b can face away from one another along the column direction C. Moreover, the first internal surface 108a is spaced between the first external surface 108b and the second sidewall 110, while the second internal surface 110a is spaced between the second external surface 110b and the first sidewall 108.

The first sidewall 108 can include a first plurality of ribs 108c that extend from the first internal surface 108a towards the second sidewall 110. The ribs 108c of the first plurality of ribs can be spaced from one another along the row direction R by a width that is greater than the width W₂ of the contact beams 216 of the electrical contacts 200 and 200′. Each rib 108c can be spaced between a different pair of immediately adjacent electrical contacts such that the edges 106 and 108 of the immediately adjacent electrical contacts that face one another also face the rib 108c.

Similarly, the second sidewall 110 can include a second plurality of ribs 110c that extend from the second internal surface 110a towards the first sidewall 108. The ribs 110c of the first plurality of ribs can be spaced from one another along the row direction R by a width that is greater than the maximum width W_max of the electrical contacts 200 and 200′. Each rib 110c can be spaced between a different pair of immediately adjacent electrical contacts such that the edges 106 and 108 of the immediately adjacent electrical contacts that face one another also face the rib 110c.

With reference to the system 10 of FIGS. 1 to 4, the system 10 can include the electrical connector 200 and at least one, or both, of (i) a first complementary electrical component 300 and (ii) a second complementary electrical component 400. The first complementary electrical component 300 can define a PCB such as an edge card. The first complementary electrical component 300 has opposed first and second side surfaces 302 and 304 that are spaced from one another along the column direction C such that the first side surface 302 mates with the electrical contacts of the first row R₁ of the electrical connector 100, and the second side surface 304 mates with the electrical contacts of the second row R₂ of the electrical connector 100. The first complementary electrical component 300 also has opposed insertion and trailing ends 306 and 308 that are spaced from one another along the select direction D, and opposed first and second edges 310 and 312 that are spaced from one another along the row direction R. The insertion end 306 can also be said to be spaced from the trailing end 308 along the mating direction M_A.

The first and second side surfaces 302 and 304 each extend from the insertion end 306 to the trailing end 308 and from the first edge 310 to the second edge 312 so as to define a planar surface having a height along the select direction D from the insertion end 306 to the trailing end 308, and a width from the first edge 310 to the second edge 312 along the row direction R. Further, the first complementary electrical component 300 defines a thickness from the first side surface 302 to the second side surface 304 along the column direction C. The height and width are greater than the thickness. Thus, the first complementary electrical component 300 is planar along the row direction R and the select direction D. The insertion end 306 can also be tapered such that the thickness of the insertion end 306 decreases in the mating direction M_A.

The first complementary electrical component 300 has a dielectric substrate 314, a first plurality of first conductive contact pads 316 carried by the substrate 314 at the first side surface 302, and a second plurality of second conductive contact pads 318 carried by the substrate 314 at the first side surface 302. Each first contact pad 316 can include a trailing end 316a, and a leading end 316b spaced from the trailing end 316a along the select direction D. Further, each first contact pad 316 can include opposed sides 316c that are spaced from one another along the row direction R, and that extend from the trailing end 316a to the leading end 316b. Each first contact pad 316 can have a rectangular shape such that each first contact pad 316 is elongate from its respective trailing end 316a to its respective leading end 316b, or can have any suitable alternative shape such as a circle, square, or other polygon. Similarly, each second contact pad 318 can include a trailing end 318a, a leading end 318b spaced from the trailing end 318a along the select direction D, and opposed sides 318c and 318d that are spaced from one another along the row direction R, and that extend from the trailing end 318a to the leading end 318b. Each second contact pad 318 can have a rectangular shape such that each second contact pad 318 is elongate from its respective trailing end 318a to its respective leading end 318b, or can have any suitable alternative shape such as a circle, square, or other polygon.

The first contact pads 316 are arranged in pairs 320 and are positioned so as to mate with the pairs 502 of the first electrical contacts 200 supported by the electrical connector 100 in the first row R₁. Thus, each pair 320 of the first contact pads 316 aligns with a different pair 502 of the first electrical contacts 200 along the column direction C when the first complementary electrical component 300 is mated with the electrical connector 100. The second contact pads 318 are positioned so as to mate with the second electrical contacts 200′ supported by the electrical connector 100 in the first row R₁. Thus, each second contact pad 318 aligns with a different second electrical contact 200′ along the column direction C when the first complementary electrical component 300 is mated with the electrical connector 100.

The second side surface 304 can carry contact pads in a pattern that substantially mirrors that of the first side surface 302. Thus, the first complementary electrical component 300 can also have a first plurality of first conductive contact pads 316 carried by the substrate 314 at the second side surface 304, and a second plurality of second conductive contact pads 318 carried by the substrate 314 at the second side surface 304, where the first and second pluralities of contact pads 316 and 318 are arranged as discussed above in relation to the first side surface 302.

The first and second pluralities of contact pads 316 and 318 can be arranged in a side-by-side manner along the row direction R. The individual first contact pads 316 within each pair 320 can be spaced apart from one another along the row direction R without any other contact pads therebetween. The pairs 320 of first contact pads 316 can be arranged such that at least one of the second contact pads 318 is disposed between adjacent pairs 320 of the first electrical contacts 316 along the row direction R. The adjacent pairs 320 of the first electrical contacts 316 can be immediately adjacent one another without any other pair 320 of the first electrical contacts 316 therebetween. Thus, the electrical contacts can be arranged along the row direction R in the following pattern: second contact pad 318-first contact pad 316-first contact pad 316-second contact pad 318-first contact pad 316-first contact pad 316, which can be repeated.

Each first contact pad 316 can define a signal contact pad, and each second contact pad 318 can define a ground contact pad. Further, each pair 320 of the first contact pads 316 can define a differential signal pair. Thus, the contact pads in the arrangement of FIGS. 1 to 5 can define the following pattern along the row direction R from left to right: ground-signal-signal-ground-signal-signal, which can be repeated. Alternatively, the plurality of first contact pads 316 can define both signal contact pads and ground contact pads and the plurality of second contact pads 318 can define both signal contact pads and ground contact pads. In particular, at least one of the first contact pads 316 can define a signal contact pad, at least one other of the first contact pads 316 can define a ground contact pad, at least one of the second contact pads 318 can define a signal contact pad, and at least one other of the second contact pads 318 can define a ground contact pad. In this case, the contact pads that define grounds and signals can alternate along the row direction R. Thus, the contact pads in the arrangement of FIGS. 1 to 5 can define the following pattern along the row direction R from left to right: ground-signal-ground-signal-ground-signal, which can be repeated.

With continuing reference to the system 10 of FIGS. 1 to 4, the second complementary electrical component 400 can be implemented as a PCB. The second complementary electrical component 400 has opposed upper and lower surfaces 402 and 404 that are spaced from one another along the select direction D, where the upper surface 402 is configured to mate with the mounting ends 202 of the electrical contacts 200 and 200′ of the electrical connector 100. The second complementary electrical component 400 also has opposed first and second ends 406 and 408 that are spaced from one another along the column direction C, and opposed first and second sides 410 and 412 that are spaced from one another along the row direction R. The lower surface 404 can also be said to be spaced from the upper surface 402 along the mounting direction M_O.

The upper and lower surfaces 402 and 404 each extend from the first end 406 to the second end 408 and from the first side 410 to the second side 412 so as to define a planar surface having a width along the column direction C from the first end 406 to the second end 408, and a length from the first side 410 to the second side 412 along the row direction R. Further, the second complementary electrical component 400 defines a thickness from the upper surface 402 to the lower surface 404 along the select direction D. The length and width are greater than the thickness. Thus, the second complementary electrical component 400 is planar along the row direction R and the column direction C.

The second complementary electrical component 400 has a dielectric substrate 414, a first plurality of first conductive contact pads 416 carried by the substrate 414 at the upper surface 402, and a second plurality of second conductive contact pads 418 carried by the substrate 414 at the upper surface 402. The first and second pluralities of conductive contact pads are arranged in first and second rows R₁ and R₂ at the upper surface 402 and that are spaced from one another along the column direction C.

Each first contact pad 416 can include a first end 416a, and a second end 416b spaced from the first end 416a along the column direction C. Further, each first contact pad 416 can include opposed sides 416c that are spaced from one another along the row direction R, and that extend from the first end 416a to the second end 416b. Each first contact pad 416 can have a rectangular shape such that each first contact pad 416 is elongate from its respective first end 416a to its respective second end 416b, or can have any suitable alternative shape such as a circle, square, or other polygon. Similarly, each second contact pad 418 can include a first end 418a, a second end 418b spaced from the first end 418a along the column direction C, and opposed sides 418c that are spaced from one another along the row direction R, and that extend from the first end 418a to the second end 418b. Each second contact pad 418 can have a rectangular shape such that each second contact pad 418 is elongate from its respective first end 418a to its respective second end 418b, or can have any suitable alternative shape such as a circle, square, or other polygon.

The first contact pads 416 within each row R₁ and R₂ are arranged in pairs 420 and are positioned so as to mate with the pairs 502 of the electrical contacts 200 supported by the electrical connector 100 in the corresponding rows R₁ and R₂ of the electrical connector 100. Thus, each pair 420 of the first contact pads 416 aligns with a different pair 502 of the electrical contacts 200 along the mounting direction M_O when the second complementary electrical component 400 is mated with the electrical connector 100. The second contact pads 418 within each row R₁ and R₂ are positioned so as to mate with the electrical contacts 200′ supported by the electrical connector 100 in the corresponding rows R₁ and R₂ of the electrical connector 100. Thus, each second contact pad 418 aligns with a different electrical contact 200′ along the mounting direction M_O when the second complementary electrical component 400 is mated with the electrical connector 100.

The first and second pluralities of contact pads 416 and 418 can be arranged in a side-by-side manner along each row R₁ and R₂. The individual first contact pads 416 within each pair 420 are spaced apart from one another along the row direction R without any other contact pads therebetween. The pairs 420 of first contact pads 416 can be arranged such that at least one of the second contact pads 418 is disposed between adjacent pairs 420 of the first electrical contacts 416 along the row direction R. The adjacent pairs 420 of the first electrical contacts 416 can be immediately adjacent one another without any other pair 420 of the first electrical contacts 416 therebetween. Thus, the electrical contacts can be arranged along the row direction R in the following pattern: second contact pad 418-first contact pad 416-first contact pad 416-second contact pad 418-first contact pad 416-first contact pad 416, which can be repeated.

Each first contact pad 416 can define a signal contact pad, and each second contact pad 418 can define a ground contact pad. Further, each pair 420 of the first contact pads 416 can define a differential signal pair. Thus, the contact pads in the arrangement of FIGS. 1 to 5 can define the following pattern along the row direction R from left to right: ground-signal-signal-ground-signal-signal, which can be repeated. Alternatively, the plurality of first contact pads 416 can define both signal contact pads and ground contact pads and the plurality of second contact pads 418 can define both signal contact pads and ground contact pads. In particular, at least one of the first contact pads 416 can define a signal contact pad, at least one other of the first contact pads 416 can define a ground contact pad, at least one of the second contact pads 418 can define a signal contact pad, and at least one other of the second contact pads 418 can define a ground contact pad. In this case, the contact pads that define grounds and signals can alternate along the row direction R. Thus, the electrical contact pads in the arrangement of FIGS. 1 to 5 can define the following pattern along the row direction R from left to right: ground-signal-ground-signal-ground-signal, which can be repeated.

Referring to FIG. 11, an electrical connector system 20 includes a first electrical connector 600, and a second electrical connector 700. The system 20 can further include first and second complementary electrical components configured as first and second substrates, such as first and second printed circuit boards (PCBs). The first electrical connector 600 is configured to be placed in electrical communication with the first complementary electrical component, and the second electrical connector 700 is configured to be placed in electrical communication with the second complementary electrical component. Thus, the first and second electrical connectors 600 and 700 can together define a mezzanine connector system that places the first complementary electrical component in electrical communication with the second complementary electrical component. In this example, the first and second electrical connectors 600 and 700 are each vertical connectors, and the system places two substantially parallel complementary electrical components in electrical communication with one another. However, in alternative embodiments, a least one of the first and second electrical connectors 600 and 700 can be a right-angle connector.

The first electrical connector 600 can define a mounting end 604 configured to be mounted to the first electrical component, and the second electrical connector 700 can define a mounting end 704 configured to be mounted to the second electrical component. Further, the first electrical connector 600 can define a mating end 606, and the second electrical connector 700 can define a mating end 706, wherein the mating ends 606 and 706 are configured to be mated with one another to provide an electrically conductive path between traces carried by the first complementary electrical component and traces carried by the second complementary electrical component. Accordingly, the electrical connectors 600 and 700 together provide an electrically conductive path between the first and second electrical components, such as from at least one of the first and second complementary electrical components to the other of the first and second complementary electrical components.

The first electrical connector 600 includes a dielectric or electrically insulative connector housing 602 and a plurality of electrical contacts 695 that are supported by the connector housing 602. For instance, the electrical contacts 695 can be arranged in at least one row that is oriented along a row direction R. For instance, the at least one row can be arranged in first and second rows R₁ and R₂ that are spaced from one another along the column direction so as to define at least one insertion slot 612 therebetween. In one example, the electrical contacts 695 can be supported by the connector housing 602 in at least first to fourth rows R₁, R₂, R₃, and R₄ that are spaced apart from one another along a column direction C so as to define a first insertion slot 612a between the first and second rows R₁ and R₂ and a second insertion slot 612b between the third and fourth rows R₃ and R₄. The rows can be oriented along a lateral direction A that is substantially perpendicular to the longitudinal direction L. The column direction C can be oriented along a direction that is perpendicular to each of the lateral direction A and the longitudinal direction L. For instance, the column direction C can be oriented along a transverse direction T. Each of the at least one row of electrical contacts can include a first set of electrical contacts 800 supported by the housing 602, and a second set of electrical contacts 900 supported by the housing 702.

The second electrical connector 700 includes a dielectric or electrically insulative connector housing 702 and a plurality of electrical contacts 795 that are supported by the connector housing 702. For instance, the electrical contacts 795 can be arranged in at least one row that is oriented along a row direction R. Further, the second electrical connector 700 can include at least one spline 712 that carries the at least one row. The at least one spline 712 can be configured to mate with the at least one insertion slot 612 of the first electrical connector 600. In one example, the electrical contacts 795 can be supported by the connector housing 702 in at least first to fourth rows R₁, R₂, R₃, and R₄ that are spaced apart from one another along a column direction C. The first and second rows R₁ and R₂ can be carried by a first spline 712a that is configured to be received by the first insertion slot 612a, and the third and fourth rows R₃ and R₄ can be carried by a second spine 712b that is configured to be received by the second insertion slot 612b. Each of the at least one row of electrical contacts can include a plurality of electrical contacts 1000 supported by the housing 702.

The second electrical connector 700 can define at least one orientation member configured to engage with a complementary orientation member of the first electrical connector 600 to ensure proper orientation of the first and second electrical connectors 600 and 700 relative to each other during mating of the first and second electrical connectors 600 and 700. In accordance with the illustrated embodiment, the second electrical connector 700 can include at least one alignment member, such as at least one post 718 that extends out from the connector housing 702 in the longitudinal direction L. For example, the at least one post 718 can extend from the mating end 706 in a direction away from the mounting end 704. Further, the first electrical connector 600 can include at least one alignment member, such as a recess 618 that extends into the first connector housing 602 in the longitudinal direction. For example, the at least one recess 618 can extend into the mating end 606 in a direction towards the mounting end 604. The at least one post 718 is configured to be received in the at least one recess 618. In at least one embodiment, the second electrical connector 700 can include two alignment members, such first and second posts 718a and 718b that are spaced from one another along the row direction R, and the first electrical connector 600 can include two alignment members, such first and second recesses 618a and 618b that are spaced from one another along the row direction R. It should be appreciated that the second electrical connector 700 is not limited to the illustrated posts 718a and 718b, and the first electrical connector 600 is not limited to the illustrated recesses 618a and 618b. Accordingly, the electrical connectors 600 and 700 can alternatively be constructed with any other suitable orientation member, or members, as desired.

Turning now to FIGS. 12 and 13, each row of contacts of the first electrical connector 600 includes a first set of electrical contacts 800 and a second set of electrical contacts 800′. Similar to the first and second electrical contacts 200 and 200′, each of the first and second contacts 800 and 800′ includes an anchoring region 814 and a contact beam 816. As will be described in further detail below, each anchoring region 814 includes one or more of a first portion 820, a second portion 826, and a third portion 826. Unless otherwise indicated, the following description of the first electrical contacts 800 will apply equally to the second electrical contact 800′.

The electrical contact 800 includes a mounting end 802, and a mating end 804 opposite the mounting end 802 along the longitudinal direction L. In one example, the electrical contact 800 can be a vertical electrical contact whereby the mating direction and mounting direction are oriented along the same direction, such as along the longitudinal direction L. Alternatively, the electrical contact 800 can be configured as a right-angle contact, whereby the mating direction and the mounting direction are oriented substantially perpendicular to each other in a manner similar to that described above in relation to FIGS. 6 and 7.

The electrical contact 800 includes a contact body 807 that defines first and second edges 806 and 808, and first and second broadsides 810 and 812. The first and second edges 806 and 808 are spaced opposite from one another along the lateral direction A. Thus, the first and second edges 806 and 808 can face away from one another. At least respective portions of the first and second broadsides 810 and 812 can be spaced opposite each other along the transverse direction T. Thus, the first and second broadsides 810 and 812 can face away from one another. It should therefore be appreciated that each of the first and second edges 806 and 808 are connected between the first and second broadsides 810 and 812. Similarly, each of the first and second broadsides 810 and 812 are connected between the first and second edges 806 and 208. The edges 806 and 808 and broadsides 810 and 812 can define respective distances along a plane that is oriented normal to the contact body 807. For instance, the edges 806 and 808 can each extend along a first distance from one of the first and second broadsides 810 and 812 to the other of the first and second broadsides 810 and 812 along the plane. The broadsides 810 and 812 can each extend along a second distance from one of the first and second edges 806 and 808 to the other of the first and second edges 806 and 808 along the plane. The second distance can be greater than the first distance. In one example, the first distance can define a thickness of the contact body 807, and the second distance can define a width of the contact body 807. The thickness along at least a portion of the contact body 807 can be oriented along the transverse direction T, and the width along at least a portion of the contact body 807 can be oriented along the lateral direction A.

The electrical contact 800 includes an anchoring region 814 that is configured to secure the electrical contact to the connector housing 602 of the electrical connector 600. The electrical contact 800 further includes a contact beam 816 that extends out with respect to the anchoring region 814. For instance, the contact beam 816 can extend out with respect to the anchoring region 814 along the longitudinal direction L. In one example, the contact beam 816 can extend from the anchoring region 814.

The contact beam 816 has first and second sides 816a and 816b, and first and second faces 816c and 816d. The first and second sides 816a and 816b of the contact beam 816 are defined by the first and second edges 806 and 808, respectively, of the contact body 807. Similarly, the first and second faces 816c and 816d of the contact beam 816 are defined by the first and second broadsides 810 and 812, respectively, of the contact body 807. The contact beam 816 can define a mating portion 817 that is configured to mate with the second complementary electrical component, and a stub 819 that extends from the mating portion 817 to the free end 818.

The anchoring region 814 extends between the mounting end 802 and the contact beam 816. For instance, the anchoring region 814 can extend from the mounting end 802 to the contact beam 816. The anchoring region 814 can define a maximum length L_max,2. Further, the anchoring region 814 can be disposed partially or fully below a midpoint of the electrical contact 800 along the longitudinal direction L. The contact beam 816 extends between a free end 818 of the electrical contact 818 and the anchoring region 814, such as from the free end 818 to the anchoring region 814, and has a maximum length L_max,3. One or more up to all of the maximum lengths of the first electrical contact 800 can be different than the corresponding one or more up to all of the maximum lengths of the second electrical contact 800′ (FIG. 13) as described in further detail below.

The anchoring region 814 can be substantially planar as it extends from the mounting end 802 to the contact beam 816 along the longitudinal direction L. For instance, the broadsides 810 and 812 can be substantially planar along respective planes that are defined by the longitudinal direction L and the lateral direction A at the anchoring region 814 from the mounting end 812 to the contact beam 816. Alternatively, the anchoring region 814 can have a bent, such as a curved, shape between the mounting end 802 and the contact beam 816.

The anchoring region 814 can include at least one of a first portion, a second portion, and a third portion. The third portion can be between the first and second portions, and thus, can be considered to be an intermediate portion. The third portion can define a width along the lateral direction A that is less than the width of at least one or both of the first and second enlarged portions along the lateral direction A. In one example, one or both of the first and second portions can extend out from the contact body 807. For instance, at least one of the first and second portions can extend out from one or both of the edges 806 and 808 along the lateral direction A. Thus, the third portion can be considered to be a narrowed portion, and one or both of the first and second portions can be considered to be enlarged portions. In one example, the anchoring region 814 can include a first portion 820, an intermediate portion 824, and a second portion 826. The intermediate portion 824 can be disposed between the first and second portions 820 and 826. In one example, the intermediate portion 824 can be defined by one or both of the edges 806 and 808 of the contact body 807.

The first portion 820 can define opposed outermost sides 820a and 820b. The outermost sides 820a and 820b can be spaced from each other along the lateral direction A. The outermost sides 820a and 820b can be outwardly spaced from the respective first and second edges 806 and 808 along the lateral direction A. The first portion 820 can have a width W₁ along the lateral direction A from the first outermost side 820a to the second outermost side 820b, the width W₁ being greater than the width W₂ of the broadsides 810 and 812 from the first edge 806 to the second edge 808. The first portion 820 can extend between the contact beam 816 and the mounting end 802, such as from the contact beam 816 towards the mounting end 802. The first portion 820 can have a substantially rectangular shape in a plane defined by the longitudinal and lateral directions as shown, or can have any other suitable shape in the plane such as a circle, square, or other polygon. Further, the first portion 820 has a maximum length L_max,4. While the outermost sides 820a and 820b of the first portion 820 can be spaced outwardly from the respective edges 806 and 808 with respect to the lateral direction A as described above, it should be appreciated that one or both of the outermost sides 820a and 820b can be continuous or in-line with the respective first and second edges 806 and 808 as desired. As will be described in further detail below, the maximum length L_max,4 of the first portion 820 of the first electrical connector 800 in FIG. 12 can be greater than the maximum length L_max,4 of the first portion 820 of the second electrical connector 800′ in FIG. 13.

The first portion 820 can extend out from at least one of the edges 806 and 808 along the lateral direction A. For instance, the first portion 820 can extend out from both edges 806 and 808 of the contact beam 816. Further portion 820 can be coplanar with the broadsides 810 and 812. In alternative embodiments, the portion 820 can extend out from only one of the first and second edges 806 and 808 along the lateral direction A. For example, one of the outermost sides 820a and 820b of the first portion 820 can be spaced outward from a corresponding one of the first and second edges 806 and 808 with respect to the lateral direction A, and the other of the sides 820a and 820b of the first portion 820 can be flush or aligned with a corresponding one of the first and second edges 806 and 808 of the contact beam 816.

The first portion 820 can define a body 820c and at least one shoulder, such as a first upper shoulder 820d that extends from the body 820c to the contact body 807, and in particular to one of the first and second edges 806 and 808. The first portion 820 can also define a second upper shoulder 820d that extends from the body 820c to the contact body 807 and in particular to the other one of the first and second edges 806 and 808. It should be appreciated that one or both of the first and second upper shoulders 820d can be omitted in some embodiments. Each upper shoulder 820d can extend from the portion 820 to the contact body 807 along a direction having a directional component along the lateral direction A.

The intermediate portion 824 can define opposed outermost sides 824a and 824b. The outermost sides 824a and 824b can be spaced from each other along the lateral direction A. In one example, the intermediate portion defines a width W₃ from one of the outermost sides 824a and 824b to the other of the outermost sides 824a and 824b. The width W₃ of the intermediate portion 824 can be less than the corresponding width of one or both of the portions 820 and 826. For instance, the width W₃ of the intermediate portion 824 can be less than the width of the broadsides 810 and 812 from one of the sides 820a and 820b to the other of the sides 820a and 820b. Alternatively, the width W₃ of the intermediate portion 824 can be greater than the width of the broadsides 810 and 812. Alternatively still, the outermost sides 824a and 824b can be defined by the first and second edges 806 and 808, respectively. Thus, the width W₃ of the intermediate portion 824 can be substantially equal to the width of the broadsides 810 and 812.

The intermediate portion 824 can extend between the first portion 820 and the mounting end 802 along the longitudinal direction L. For instance, the intermediate portion 824 can extend from the first portion 820 toward the mounting end 802. The intermediate portion 824 can define a maximum length L_max,5 along the longitudinal direction L. The intermediate portion 824 can have a substantially rectangular shape in a plane defined by the longitudinal and lateral directions as shown, or can have any other suitable shape in the plane such as a circle, square, or other polygon. Further, the first outermost side 824a can be linear as it extends from the first portion 820 towards the mounting end 802. Similarly, the second outermost side 824b can be linear as it extends from the first portion 820 towards the mounting end 802. As will be described in further detail below, the intermediate portion 824 of the second electrical connector 800′ in FIG. 13 can be offset from the intermediate portion 824 of the first electrical connector 800 in FIG. 12 with respect to the longitudinal direction L.

The first portion 820 can define at least one lower shoulder, such as a first lower shoulder 820e that extends from the body 820c of the first portion 820 to the intermediate portion 824. For instance, the first lower shoulder 820e can extend from one of the outermost sides 820a and 820b to a corresponding one of the outermost sides 824a and 824b. The first portion 820 can also define a second lower shoulder 820e that extends from the body 820c to the intermediate portion 824. For instance, the second lower shoulder 820e can extend the other of the outermost sides 820a and 820b to the corresponding other of the outermost sides 824a and 824b. It should be appreciated that one or both of the first and second lower shoulders 820e can be omitted in some embodiments. Each lower shoulder 820e can extend from the portion 820 to the intermediate portion 824 along a direction having a directional component along the lateral direction A. Further, each lower shoulder 820e can face away from a corresponding upper shoulder 820d.

The second portion 826 can define opposed outermost sides 826a and 826b. The outermost sides 826a and 826b can be spaced from each other along the lateral direction A. The outermost sides 826a and 826b can be outwardly spaced from the respective first and second sides 824a and 824b of the intermediate portion 824 along the lateral direction A. The outermost sides 826a and 826b can also be outwardly spaced from the respective first and second edges 806 and 808 along the lateral direction A. The second portion 826 can have a width W₄ along the lateral direction A from the first outermost side 826a to the second outermost side 826b, the width W₄ being greater than the width W₂ of the broadsides 810 and 812 from the first edge 806 to the second edge 808. The second portion 826 can extend between the contact beam 816 and the mounting end 802, such as from the mounting end 802 towards the contact beam 816. The second portion 826 can have a substantially rectangular shape in a plane defined by the longitudinal and lateral directions as shown, or can have any other suitable shape in the plane such as a circle, square, or other polygon. Further, the second portion 826 has a maximum length L_max,6. While the outermost sides 826a and 826b of the second portion 826 can be spaced outwardly from the respective first and second sides 824a and 824b with respect to the lateral direction A as described above, it should be appreciated that one or both of the outermost sides 826a and 826b can be continuous with the respective first and second sides 824a and 824b as desired. As will be described in further detail below, the maximum length L_max,6 of the second portion 826 of the first electrical connector 800 in FIG. 12 can be less than the maximum length L_max,6 of the second portion 826 of the second electrical connector 800′ in FIG. 13.

The second portion 826 can extend outward from at least one of the sides 824a and 824b of the intermediate portion 824 along the lateral direction A. For instance, the second portion 826 can extend outward from both of the sides 824a and 824b of the intermediate portion 824. Further, the second portion 826 can be coplanar with the broadsides 810 and 812. In alternative embodiments, the second portion 826 can extend out from only one of the first and second sides 824a and 824b along the lateral direction A. For example, one of the outermost sides 826a and 826b of the second portion 826 can be spaced outward from a corresponding one of the first and second sides 824a and 824b with respect to the lateral direction A, and the other of the sides 826a and 826b of the second portion 826 can be flush or aligned with a corresponding one of the first and second sides 824a and 824b of the intermediate portion.

The second portion 826 can define a body 826c and at least one shoulder, such as a first upper shoulder 826d that extends from the body 826c to the intermediate portion 824, and in particular to one of the first and second sides 824a and 824b of the intermediate portion 824. The second portion 826 can also define a second upper shoulder 826d that extends from the body 826c to the intermediate portion 824, and in particular to the other one of the first and second sides 824a and 824b of the intermediate portion 824. It should be appreciated that one or both of the first and second upper shoulders 826d can be omitted in some embodiments. Each upper shoulder 820d can extend from the portion 826 to the contact body intermediate portion 824 along a direction having a directional component along the lateral direction A. Further, each upper shoulder 826c can face towards a corresponding lower shoulder 820c of the first portion 820.

The second portion 826 can define at least one lower shoulder, such as a first lower shoulder 826e that extends from the body 826c of the second portion 826 to the mounting tail 834. For instance, the first lower shoulder 826e can extend from one of the outermost sides 826a and 826b to a corresponding side of the mounting tail 834. The second portion 826 can also define a second lower shoulder 826e that extends from the body 826c of the second portion 826 to the mounting tail 834. For instance, the second lower shoulder 826e can extend from the other one of the outermost sides 826a and 826b to a corresponding side of the mounting tail 834. It should be appreciated that one or both of the first and second lower shoulders 826e can be omitted in some embodiments. Each lower shoulder 826e can extend from the portion 826 to the mounting tail 834 along a direction having a directional component along the lateral direction A. Further, each lower shoulder 826e can face away from a corresponding upper shoulder 826d.

As will become appreciated from the description below, at least one first and second portions of the second electrical contact 800′ is configured to reside at a location aligned with the intermediate portion 824 of the first electrical contact 800 along the lateral direction A. Similarly, at least one first and second portions of the first electrical contact 800 is configured to reside at a location aligned with the intermediate portion 824 of the second electrical contact 800′ along the lateral direction A.

The anchoring regions 814 of each of the first and second electrical contacts 800 and 800′ can include at least one retention feature 822 that is configured to engage the connector housing 602 so as to secure the electrical contact to the connector housing 602. For example, each anchoring region can include two retention features 822 that are spaced from one another along the lateral direction A. The two retention features 822 can be aligned along the lateral direction A. Each retention feature 822 can define a barb having a first barb end 822a that is connected to the body of the anchoring region 814 in a hinged manner. Each retention feature 822 can further include a second, or free, barb end 822b that is opposite the first barb end 822a and is free from attachment to the body of the anchoring region 814. As shown, the second barb end 822b can be spaced from the first barb end 822a along the longitudinal direction L, and the hinge can be configured to bend about an axis that extends along the lateral direction A so as to offset the second barb end 822b from the first barb end 822a along the transverse direction T. Alternatively, the second barb end 822b can be spaced from the first barb end 822a along the lateral direction A, and the hinge can be configured to bend about an axis that extends along the longitudinal direction L so as to offset the second barb end 822b from the first barb end 822a along the transverse direction T. Note that, in alternative embodiments, the at least one retention feature 822 can define a feature other than a barb, such as (without limitation) a fixed protrusion, or a recess that receives a protrusion on the connector housing 602, or the at least one retention feature 822 can be omitted altogether.

In FIG. 12, the first barb end 822a of each retention feature 822 is connected to the body 820c of the first portion 820. For example, the contact 800 can include a first retention feature 822 connected to the body 820c at the first side 820a of the first portion 820, and a second retention feature 822 connected to the body 820c at the second side 820b of the first portion 820. Further, each retention feature 822 extends from the body 820c towards the intermediate portion 824 along the longitudinal direction L. In one example, each retention feature 822 can extend from the body 820c and terminate at or before the intermediate portion 824.

In FIG. 13, the first barb end 822a of each retention feature 822 is connected to the body 824c of the intermediate portion 824. For example, the contact 800′ can include a first retention feature 822 connected to the body 824c at the first side 824a of the intermediate portion 824, and a second retention feature 822 connected to the body 824c at the second side 824b of the intermediate portion 824. Further, each retention feature 822 extends from the body 824c towards the second portion 826 along the longitudinal direction L. In one example, each retention feature 822 can extend from the body 824c and terminate at the second portion 826. For instance, each retention feature 822 can include an upper shoulder 826d of the second portion 826. Thus, as will be further described below, the retention features 822 of the second electrical contact 800′ can be offset from the retention features 822 of the first electrical contact 800 with respect to the longitudinal direction L.

The contact beam 816 can be constructed as a flexible beam having a bent, such as curved, shape that extends from the anchoring region 814 to a free end 818 of the electrical contact 800. Bent structures as described herein refer to bent shapes that can be fabricated, for instance, by bending the end or by stamping a bent shape, or by any other suitable manufacturing process. The first broadside 810 at the contact beam 816 is configured to wipe against a corresponding electrical contact 900 of the second electrical connector 700 as the connector is mated with the contact beam 816 along the longitudinal direction L. Further, the contact beam 816 is configured to contact the corresponding contact 900 second electrical connector 700 so as to apply a force to the corresponding contact 900 along the transverse direction T.

The contact beam 816 can include at least a first bend region 829 between the anchoring region 814 and the mating end 804. The first bend region 829 can curve towards a first direction that extends from the second broadside 812 toward the first broadside 810 as the contact beam 816 extends away from the anchoring region 814 along the longitudinal direction L. The contact beam 816 can further include at least a second bend region 830 that is between the first bend region 829 and the mating end 804. The second bend region 829 can curve towards a second direction, opposite the first direction, that extends from the first broadside 810 toward the second broadside 812 as the contact beam 816 extends away from the first bend region 829 along the longitudinal direction L. The contact beam 816 can include at least a third bend region 832 between the second bend region 830 and the mating end 804. The third bend region 832 can curve towards the first direction that extends from the second broadside 812 toward the first broadside 810 as the contact beam 816 extends away from the second bend region 830 along the longitudinal direction L. In alternative embodiments, the curvature of the contact beam 816 can vary from that shown. For example, the contact beam 816 can include as few as one bend region, or greater than two bend regions.

The anchoring region 814 can define a central axis CA that extends in the longitudinal direction between the first and second broadsides 810 and 812. One or more of the second bend region 830, the third bend region 832, and the free end 818 can extend at least partially on a first side of the central axis CA with respect to the transverse direction T, the first side being spaced from the central axis CA along a direction that is opposite the first broadside 212.

The mounting end 802 can include a mounting tail 834 that extends away from the anchoring region 814 along the longitudinal direction L. For example, the mounting tail 834 can define a press-fit tail that is coplanar with the anchoring region 814. In alternative embodiments, the mounting tail 834 can be configured as a surface-mount tail, as a differently-configured press-fit tail, as a fusible element such as a solder ball, or combinations thereof. The electrical contact 800 defines maximum length L_max,1 along the longitudinal direction L from the free end 818 to the terminal end 836. The electrical contact 800 further defines a maximum width W_max,1 along the lateral direction A. The maximum width W_max,1 can be equal to at least one of the width W₁ of the first portion 820 and the width W₄ of the second portion 826, such as a larger of the widths W₁ and W₄. Alternatively, the maximum width W_max,1 can be equal to both the width W₁ of the first portion 820 and the width W₄ of the second portion 826 when the widths W₁ and W₄ are equal. The contact body 807 yet further defines a maximum thickness T_max along the transverse direction T from one of the opposed broadsides 810 and 812 to the other. The maximum length L_max,1 of the electrical contact 800 is greater than both the maximum width W_max,1 and the maximum thickness T_max. Further, the maximum width W_max,1 of the electrical contact 800 can be greater than the maximum thickness T_max. Thus, the electrical contact 800 can be said to be elongate along the longitudinal direction L.

Turning now to FIG. 14, embodiments of the present disclosure can include a kit having at least one first electrical contact 800 and at least a second electrical contact 800′. For instance, the kit can have a first set of the first electrical contacts 800 and a second set of the second electrical contacts 800′. The first and second electrical contacts 800 and 800′ can be arranged edge-to-edge in a row of the electrical connector 600. Further, the first and second electrical contacts 800 and 800′ can be arranged such that the mounting ends 802 of the first and second electrical contacts 800 and 800′ are aligned along the lateral direction A. In this arrangement, the anchoring regions 814 of the first and second electrical contacts 800 and 800′ can be aligned along the lateral direction A.

The anchoring region 814 of each of the first and second electrical contacts 800 and 800′ can define an upper-most point and a lower-most point, the upper-most point being closer to the mating end of the electrical contact, and the lower-most point being closer to the mounting end of the electrical contact 800. In one example, the upper-most points of one or more, up to all, of the anchoring regions 814 of the first electrical contacts 800 can be aligned with the upper-most points of one or more, up to all, of the anchoring regions 814 of the second electrical contacts 800′ along the lateral direction A. Further, lower-most points of one or more, up to all, of the anchoring regions 814 of the first electrical contacts 800 can be aligned with the lower-most points of one or more, up to all, of the anchoring regions 814 of the second electrical contacts 800′ along the lateral direction A. Alternatively, at least one of (i) the upper-most points of the anchoring regions 814 of the first and second electrical contacts 800 and 800′ can be offset from one another, and (ii) the lower-most points of the anchoring regions 814 of the first and second electrical contacts 800 and 800′ can be offset from one another.

The first portions 820 of the first and second electrical contacts 800 and 800′ can each define a center. The centers of the first portions 820 of the first electrical contacts 800 can be aligned along a first line that extends substantially along the lateral direction A. Similarly, the centers of the first portions 820 of the second electrical contacts 800′ can be aligned along a second line that extends substantially along the lateral direction A. The second line can be offset from the first line along the longitudinal direction L. For instance, the second line can be closer to the mounting ends 802 than the first line. Further, the second line can be substantially parallel to the first line.

The intermediate portions 824 of each adjacent pair of first and second electrical contacts 800 and 800′ can be offset relative to one another with respect to the lateral direction A. For example, the intermediate portion 824 of each first electrical contact 800 is aligned with the second portion 826 of each second electrical contact 800′ along the lateral direction A. Further, the intermediate portion 824 of each second electrical contact 800′ is aligned with the first portion 826 of each first electrical contact 800 along the lateral direction A. In at least some embodiments, the intermediate portion 824 and the second portion 826 of each first electrical contact 800 can be aligned with the second portion 826 of each second electrical contact 800′ along the lateral direction A. Further, the intermediate portion 824 and first portion 820 of each second electrical contact 800′ can aligned with the first portion 826 of each first electrical contact 800 along the lateral direction A.

Additionally, or alternatively, the retention features 822 of each adjacent pair of first and second electrical contacts 800 and 800′ can be staggered relative to one another with respect to the longitudinal direction L. For example, the at least one retention feature 822 of each first electrical contact 800 can be disposed closer to the mating ends 804 of the contacts with respect to the longitudinal direction L than the at least one retention feature of each second electrical contact 800′. Further, the at least one retention feature 822 of each second electrical contact 800′ can be disposed closer to the mounting ends 802 of the contacts with respect to the longitudinal direction L than the at least one retention feature of each first electrical contact 800. For example, a distance from the free end 818 of each first electrical contact 800 to the at least one retention feature 822 of the first electrical contact 800 can be less than a distance from the free end 818 of each second electrical contact 800′ to its at least one retention feature 822. Further, a distance from the mounting tail 834 of each second electrical contact 800′ to the at least one retention feature 822 of the second electrical contact 800′ can be less than a distance from the mounting tail 834 of each first electrical contact 800 to its at least one retention feature 822.

Each first electrical contact 800 can have a maximum length L_max,1 along the longitudinal direction L from the mounting end 802 of the first electrical contact 800 to the mating end 804 of the first electrical contact 800 that is substantially equal to a maximum length L_max,1 of the second electrical contact 800′ along the longitudinal direction L from the mounting end 802 of the second electrical contact 800′ to the mating end 804 of the second electrical contact 800′. The anchoring region 814 of the first electrical contact 800 can have a maximum length L_max,2 that is substantially equal to a maximum length L_max,2 of the anchoring region 814 of the second electrical contact 800′. The intermediate portion 824 of the first electrical contact 800 can have a maximum length L_max,5 that is substantially equal to a maximum length L_max,5 of the intermediate portion 824 of the second electrical contact 800′. The first portion 820 of the first electrical contact 800 can have a maximum length L_max,4 that is greater than a maximum length L_max,4 of the first enlarged 820 of the second electrical contact 800′. The second portion 826 of the first electrical contact 800 can have a maximum length L_max,6 that is less than a maximum length L_max,6 of the second portion 826 of the second electrical contact 800′. The contact beam 816 of the first electrical contact 800 can have a maximum length L_max,3 that is substantially equal to a maximum length L_max,3 of the contact beam 816 of the second electrical contact 200′. In alternative embodiments, at least one of the maximum length L_max,1 of the first electrical contact 800, the maximum length of the anchoring region 814 of the first electrical contact 800, the maximum length L_max,5 of the intermediate portion 824 of the first electrical contact 800, and the maximum length L_max,3 of the contact beam 816 of the first electrical contact 800 can vary from the corresponding dimension of the second electrical contact 800′.

In at least one embodiment, the contacts 800 and 800′ within each row can define an open pin field, or each of the contacts 800 and 800′ can alternatively be designated as a signal or ground. Each first electrical contact 800 can each define either a signal contact or a ground contact, and each second electrical contact 800′ can define either a signal contact or a ground contact. For example, the first and second sets of the contacts can be spaced along the row direction R in alternating fashion such that each pair of adjacent first contacts 800 are separated by a second contact 800′, and each pair of adjacent second contacts 800′ are separated by a first contact 800. For instance, the electrical contacts can define the following pattern along the row direction R from left to right: ground-signal-ground-signal-ground-signal, which can be repeated. It will be appreciated that other patterns are possible.

Turning now to FIG. 15, each row of contacts of the second electrical connector 700 includes a set of third electrical contacts 900. Each of the third contacts 900 includes an anchoring region 914 and a contact beam 916. As will be described in further detail below, each anchoring region 914 includes one or more portions 920, 924, and 926.

The electrical contact 900 includes a mounting end 902, and a mating end 904 opposite the mounting end 902 along the longitudinal direction L. In one example, the electrical contact 900 can be a vertical electrical contact whereby the mating direction and mounting direction are oriented along the same direction, such as along the longitudinal direction L. Alternatively, the electrical contact 900 can be configured as a right-angle contact, whereby the mating direction and the mounting direction are oriented substantially perpendicular to each other in a manner similar to that described above in relation to FIGS. 6 and 7.

The electrical contact 900 includes a contact body 907 that defines first and second edges 906 and 908, and first and second broadsides 910 and 912. The first and second edges 906 and 908 are spaced opposite from one another along the lateral direction A. Thus, the first and second edges 906 and 908 can face away from one another. At least respective portions of the first and second broadsides 910 and 912 can be spaced opposite each other along the transverse direction T. Thus, the first and second broadsides 910 and 912 can face away from one another. It should therefore be appreciated that each of the first and second edges 906 and 908 are connected between the first and second broadsides 910 and 912. Similarly, each of the first and second broadsides 910 and 912 are connected between the first and second edges 906 and 908. The edges 906 and 908 and broadsides 910 and 912 can define respective distances along a plane that is oriented normal to the contact body 907. For instance, the edges 906 and 908 can each extend along a first distance from one of the first and second broadsides 910 and 912 to the other of the first and second broadsides 910 and 912 along the plane. The broadsides 910 and 912 can each extend along a second distance from one of the first and second edges 906 and 908 to the other of the first and second edges 906 and 908 along the plane. The second distance can be greater than the first distance. In one example, the first distance can define a thickness of the contact body 907, and the second distance can define a width of the contact body 907. The thickness along at least a portion of the contact body 907 can be oriented along the transverse direction T, and the width along at least a portion of the contact body 907 can be oriented along the lateral direction A.

The electrical contact 900 includes an anchoring region 914 that is configured to secure the electrical contact to the connector housing 702 of the electrical connector 700. The electrical contact 900 further includes a contact beam 916 that extends out with respect to the anchoring region 914. For instance, the contact beam 916 can extend out with respect to the anchoring region 914 along the longitudinal direction L. In one example, the contact beam 916 can extend from the anchoring region 914.

The contact beam 916 has first and second sides 916a and 916b, and first and second faces 916c and 916d. The first and second sides 916a and 916b of the contact beam 916 are defined by the first and second edges 906 and 908, respectively, of the contact body 907. Similarly, the first and second faces 916c and 916d of the contact beam 916 are defined by the first and second broadsides 910 and 912, respectively, of the contact body 907. The contact beam 916 can define a mating portion 917 that is configured to mate with the second complementary electrical component, and a stub 919 that extends from the mating portion 917 to the free end 918.

The anchoring region 914 extends between the mounting end 902 and the contact beam 916. For instance, the anchoring region 914 can extend from the mounting end 902 to the contact beam 916. The anchoring region 914 can define a maximum length L_max,2 from the mounting end 902 to the contact beam 916. Further, the anchoring region 914 can be disposed partially or fully below a midpoint of the electrical contact 900 along the longitudinal direction L. The contact beam 916 extends between a free end 918 of the electrical contact 918 and the anchoring region 914, such as from the free end 918 to the anchoring region 914, and has a maximum length L_max,3.

The anchoring region has a body 914c that includes opposed first and second sides 914a and 914b that are spaced from one another along the lateral direction A. The anchoring region 914 can be substantially planar as it extends from the mounting end 902 to the contact beam 916 along the longitudinal direction L. For instance, the broadsides 910 and 912 can be substantially planar along respective planes that are defined by the longitudinal direction L and the lateral direction A at the anchoring region 914 from the mounting end 912 to the contact beam 916. Alternatively, the anchoring region 914 can have a bent, such as a curved, shape between the mounting end 902 and the contact beam 916.

The anchoring region 914 can include at least one portion. In one example, the anchoring region 914 can include a first portion 920, a second portion 926, and a third portion 924. The third portion 924 can be between the first and second portions 920 and 926, and thus can be considered to be an intermediate portion. The first portion 920 can extend between the contact beam 916 and the mounting end 902. For example, the first portion 920 can extend from the contact beam 916 toward the mounting end 902. The first portion 920 can have a body 920c that defines opposed outermost sides 920a and 920b. The outermost sides 920a and 920b can be spaced from each other along the lateral direction A. The second outermost side 920b can be outwardly spaced from the second edge 908 along the lateral direction A. The first outermost side 920a can extend up to the first edge 906. For example, the first outermost side 920a can be spaced inwardly from, or be aligned with, the first edge 906. In some embodiments, as shown in FIG. 15, the first portion 920a can be considered to be a first jogged portion. The first portion 920 has a maximum length L_max,4. Further, the first portion 920 can be coplanar with the broadsides 910 and 912.

The second portion 926 can extend between the mounting end 902 and the intermediate portion 924. For example, the second portion 926 can extend from the mounting end 902 towards the intermediate portion 924. The second portion 926 can have a body 926c that defines opposed outermost sides 926a and 926b. The outermost sides 926a and 926b can be spaced from each other along the lateral direction A. The second outermost side 926b can be outwardly spaced from the second edge 908 along the lateral direction A. The first outermost side 926a can extend up to the first edge 906. For example, the first outermost side 926a can be spaced inwardly from, or be aligned with, the first edge 906. In some embodiments, as shown in FIG. 15, the second portion 926a can be considered to be a second jogged portion. The second portion 926 has a maximum length L_max,6. Further, the second portion 926 can be coplanar with the broadsides 910 and 912.

The intermediate portion 924 can extend between the first portion 920 and the mounting end 902. For example, the intermediate portion 924 can extend from the first portion 920 towards the mounting end 902. The intermediate portion 924 have a body 924c that defines opposed outermost sides 924a and 924b. The outermost sides 924a and 924b can be spaced from each other along the lateral direction A. The first outermost side 924b can be outwardly spaced from the first edge 906 along the lateral direction A. The second outermost side 924b can extend up to the second edge 908. For example, the second outermost side 924b can extend inward from, or be aligned with, the second edge 908. In some embodiments, as shown in FIG. 15, the intermediate portion 924a can be considered to be a third jogged portion. The intermediate portion 924 has a maximum length L_max,5. Further, the intermediate portion 924 can be coplanar with the broadsides 910 and 912.

The contact beam 916 can define a central axis CA that extends in the longitudinal direction between the first and second edges 906 and 908. The first side 920a of the first portion 920 can be spaced closer to the central axis CA than the second side 920b of the first portion 920. In one example, the first portion 920 can have a central axis that is offset from the central axis CA of the contact beam 916 along a first lateral direction that extends from the first edge 906 towards the second edge 908. Thus, it can be said that the first portion 920 is offset from the central axis CA along the first lateral direction. The second side 924b of the intermediate portion 924 can be spaced closer to the central axis CA than the first side 924a of the intermediate portion 924. In one example, the intermediate portion 924 can have a central axis that is offset from the central axis CA of the contact beam 916 along a second lateral direction that is opposite the first lateral direction and that extends from the second edge 908 towards the first edge 906. Thus, it can be said that the intermediate portion 924 is offset from the central axis CA along the second lateral direction. The first side 926a of the second portion 926 can be spaced closer to the central axis CA than the second side 926b of the second portion 926. In one example, the second portion 926 can have a central axis that is offset from the central axis CA of the contact beam 916 along the first lateral direction that extends from the first edge 906 towards the second edge 908. Thus, it can be said that the second portion 926 is offset from the central axis CA along the first lateral direction. It will be appreciated that, in other examples, the directions of the first, second, and third portions can be reversed.

The anchoring region 914 can include at least one retention feature 922 that is configured to engage the connector housing 702 so as to secure the electrical contact to the connector housing 702. Each retention feature 922 can define a barb having a first barb end 921 that extends from the body 914c of the anchoring region 914 in a hinged manner. Each retention feature 922 can further include a second, or free, barb end 923 that is opposite the first barb end 921 and is free from attachment to the body 914c of the anchoring region 914. As shown, the second barb end 923 can be spaced from the first barb end 921 along the longitudinal direction L, and the hinge can be configured to bend about an axis that extends along the lateral direction A so as to offset the second barb end 923 from the first barb end 921 along the transverse direction T. Alternatively, the second barb end 923 can be spaced from the first barb end 921 along the lateral direction A, and the hinge can be configured to bend about an axis that extends along the longitudinal direction L so as to offset the second barb end 923 from the first barb end 921 along the transverse direction T. Note that, in alternative embodiments, the at least one retention feature 922 can define a feature other than a barb, such as (without limitation) a fixed protrusion, or a recess that receives a protrusion on the connector housing 702, or the at least one retention feature 922 can be omitted altogether.

In the illustrated example of FIG. 15, the anchoring region 914 has first and second retention features 922a and 922b that define first and second barbs. The first retention feature 922a can be connected to the body 914c at the first side 914a of the anchoring region 914 and the second retention feature 922b can be connected to the body 914c at the second side 914b of the anchoring region 914. Thus, the first and second retention features 922a and 922b can be offset from one another with respect to the lateral direction A. The first retention feature 922a can be connected to the body 914c at a location closer to the mating end 904 than the second retention feature 922b. Accordingly, the second retention feature 922b can be connected to the body 914c at a location closer to the mounting end 902 than the first retention feature 922a. Thus, the first and second retention features 922a and 922b can be offset from one another with respect to the longitudinal direction L.

In the illustrated example, the first barb end 921 of the first retention feature 922a can be connected to the body 924c of the intermediate portion 924. Further, the first retention feature 922a can extend toward the second portion 926. The first retention feature 922a can also terminate before the second portion 926. The first barb end 921 of the second retention feature 922b can be connected to the body 926c of the second portion 926. Further, the second retention feature 922b can extend toward the mounting tail 934. The second retention feature 922b can also terminate before the mounting tail 934.

The contact beam 916 can be constructed as a flexible beam having a bent, such as curved, shape that extends from the anchoring region 914 to a free end 918 of the electrical contact 900. Bent structures as described herein refer to bent shapes that can be fabricated, for instance, by bending the end or by stamping a bent shape, or by any other suitable manufacturing process. The first broadside 910 at the contact beam 916 is configured to wipe against a corresponding electrical contact 800, 800′ of the first electrical connector 600 as the connector is mated with the contact beam 916 along the longitudinal direction L. Further, the contact beam 916 is configured to contact the corresponding contact 800, 800′ of the first electrical connector 600 so as to apply a force to the corresponding contact 800, 800′ along the transverse direction T.

The contact beam 916 can include at least one bend region 930 between the anchoring region 914 and the mating end 904. The at least one bend region 830 can curve towards a first direction that extends from the second broadside 912 toward the first broadside 910 as the contact beam 916 extends away from the anchoring region 914 along the longitudinal direction L. In alternative embodiments, the curvature of the contact beam 916 can vary from that shown. For example, the contact beam 916 can include more than one bend region, or can have a bend region that is located other than as shown.

The mounting end 902 can include a mounting tail 934 that extends away from the anchoring region 814 along the longitudinal direction L. For example, the mounting tail 934 can define a press-fit tail that is coplanar with the anchoring region 914. In alternative embodiments, the mounting tail 934 can be configured as a surface-mount tail, as a differently-configured press-fit tail, as a fusible element such as a solder ball, or combinations thereof. The electrical contact 900 defines maximum length L_max,1 along the longitudinal direction L from the free end 918 to the terminal end 936 of the mounting tail 934. The electrical contact 900 further defines a maximum width W_max,1 along the lateral direction A. The contact body 907 yet further defines a maximum thickness T_max along the transverse direction T from one of the opposed broadsides 910 and 912 to the other. The maximum length L_max,1 of the electrical contact 900 is greater than both the maximum width W_max,1 and the maximum thickness T_max. Further, the maximum width W_max,1 of the electrical contact 900 can be greater than the maximum thickness T_max. Thus, the electrical contact 900 can be said to be elongate along the longitudinal direction L.

Turning now to FIG. 16, embodiments of the present disclosure can include a kit having a plurality of the third electrical contact 900. The plurality of electrical contacts 900 can be arranged edge-to-edge in a row of the electrical connector 700. Further, the electrical contacts 900 can be arranged such that their respective mounting ends 902 are aligned along the lateral direction A. In this arrangement, the anchoring regions 914 of the plurality of electrical contacts 900 can be aligned along the lateral direction A. The anchoring regions 914 of each of the plurality of electrical contacts 900 can define an upper-most point and a lower-most point, the upper-most point being closer to the mating end of the electrical contact, and the lower-most point being closer to the mounting end of the electrical contact 900. In one example, the upper-most points of two or more, up to all, of the anchoring regions 914 of the first electrical contacts 900 can be aligned with one another along the lateral direction A. Further, lower-most points of two or more, up to all, of the anchoring regions 914 of the electrical contacts 900 can be aligned with one another along the lateral direction A.

Each jogged portion of an electrical contact 900 can be aligned with a corresponding jogged portion of the other electrical contacts 900 in the plurality of contacts along the lateral direction A. For example, the first portions 920 of the electrical contacts 900 can be aligned along the lateral direction A, the second portions 924 of the electrical contacts 900 can be aligned along the lateral direction A, and the third portions 926 of the electrical contacts 900 can be aligned along the lateral direction A. Further, each first portion 920 is offset along the first lateral direction from the first edge 906 toward the second edge 908, each second intermediate is offset along the second lateral direction, opposite the first lateral direction, and each second portion 926 is offset along the first lateral direction. Without being bound by theory, it is believed that offsetting jogged portions can improve impedance matching at the anchoring regions 914 of the contacts 900.

The first retention features 922a of the electrical contacts 900 can be aligned with one another along the lateral direction A, and the second retention features 922b of the electrical contacts 900 can be aligned with one another along the lateral direction A. The first retention feature 922a of each electrical contact 900 can be connected to the body 914c of the anchoring region 914 at the first side 914a of the anchoring region 914. As a result, the first retention features 922a can be evenly spaced across the row direction. Similarly, the second retention feature 922b of each electrical contact 900 can be connected to the body 914c of the anchoring region 914 at the second side 914b of the anchoring region 914. As a result, the second retention features 922b can be evenly spaced across the row direction.

The electrical contacts 900 within each row can define an open pin field, or each contact 900 can be designated as either a signal or a ground. In one example, the electrical contacts can define the following pattern along the row direction R from left to right: ground-signal-ground-signal-ground-signal, which can be repeated. It will be appreciated that other patterns are possible.

Referring to FIGS. 17-20, an electrical connector system 1000 includes an electrical connector 1100, a first complementary electrical component 1200, and a second complementary electrical component 1300. The first complementary electrical component 1200 can be configured as a first substrate, such as a first printed circuit board (PCB). Similarly, the second electrical component 1300 can be a second substrate, such as a second PCB. The electrical connector 1100 is configured to be placed in electrical communication with each of the first and second electrical components 1200 and 1300. For instance, the electrical connector 1100 can be mounted to the first electrical component 1200. The second electrical component 1300 can define an edge card that is configured to be received by the electrical connector 1100 along a longitudinal direction L so as to mate the electrical connector 1100 with the second electrical component. It is thus appreciated that the electrical connector can be configured to electrically couple the first and second complementary electrical components 1200 and 1300 to one another. Accordingly, the electrical connector 1100 provides an electrically conductive path between the first and second electrical components 1200 and 1300, such as from at least one of the first and second complementary electrical components 1200 and 1300 to the other of the first and second complementary electrical components 1200 and 1300.

The electrical connector 1100 includes a dielectric or electrically insulative connector housing 1102 and a plurality of electrical contacts 1120 that are supported by the connector housing 1102. For instance, the electrical contacts 1120 can be arranged in at least one row that is oriented along a row direction R. The at least one row of the electrical contacts 1120 can be supported by at least one dielectric or electrically insulative insert mold body 1118 that is in turn supported by the connector housing 1102. Thus, the electrical connector 1100 can include at least one insert mold assembly 1122 that includes the at least one insert mold body 1118 and the at least one row of electrical contacts 1120.

In one example, the electrical contacts 1120 can be supported by the connector housing 1102 in at least first and second rows R₁ and R₂ that are spaced apart from one another along a column direction C so as to define an insertion slot 1112 between the first and second rows R₁ and R₂. The first row R₁ of electrical contacts 1120 can be supported by a first insert mold body 1118a and the second row R₂ can be supported by a second insert mold body 1118b. Thus, the electrical connector can include a first insert mold assembly 1122a that includes the first insert mold body 1118a and the first row R₁ of electrical contacts, and a second insert mold assembly 1122b that includes the second insert mold body 1122b and the second row R₂ of electrical contacts.

The rows R₁ and R₂ can be oriented along a lateral direction A that is substantially perpendicular to the longitudinal direction L. The column direction C can be oriented along a direction that is perpendicular to each of the lateral direction A and the longitudinal direction L. For instance, the column direction C can be oriented along a transverse direction T.

Each of the at least one row of electrical contacts can include a first set 1140 of electrical contacts supported by the housing 1102, and a second set 1150 of electrical contacts supported by the housing 1102. The first set 1140 of electrical contacts in each row can include at least one pair 1142 of adjacent electrical contacts 1144 and 1146. For instance, the first set 1140 can include a plurality of pairs 1142 of adjacent electrical contacts. In some embodiments, the at least one pair 1142 of adjacent electrical contacts can be configured as a pair of signal contacts, although, as will be discussed in further detail below, embodiments of the disclosure are not so limited. The second set 1150 of electrical contacts in each row can include a plurality of individual electrical contacts 1152. In some embodiments, the individual electrical contacts 1152 can be configured as ground contacts, although, as will be discussed in further detail below, embodiments of the disclosure are not so limited.

Turning now to FIGS. 21 to 23, the first electrical contact 1144 of each pair 1142 can include a mounting end 1402, and a mating end 1404 opposite the mounting end 1402 along the longitudinal direction L. The mounting end 1402 is configured to be mounted onto, for example, the first complementary electrical component 1200 along a mounting direction. The mating end 1404 is configured to mate with, for example, the second complementary electrical component 1300 along a mating direction. In one example, the mating direction and mounting direction can be oriented along the same direction. For instance, the mating direction and mounting direction can be oriented along the longitudinal direction L. Thus, the first electrical contact 1144 is considered to be a vertical electrical contact. Alternatively, the first electrical contact 1144 can be configured as a right-angle contact, whereby the mating direction and the mounting direction are oriented substantially perpendicular to each other. For instance, when the electrical contact 1144 is configured as a right-angle contact, the mounting end 1402 can be oriented along the longitudinal direction L, and the mating end 1404 can be oriented along the transverse direction T.

The electrical contact 1144 includes a contact body 1407 that defines first and second edges 1406 and 1408, and first and second broadsides 1410 and 1412. The first and second edges 1406 and 1408 are spaced opposite from one another along the lateral direction A. Thus, the first and second edges 1406 and 1408 can face away from one another. At least respective portions of the first and second broadsides 1410 and 1412 can be spaced opposite each other along the transverse direction T. Thus, the first and second broadsides 1410 and 1412 can face away from one another. It should therefore be appreciated that each of the first and second edges 1406 and 1408 are connected between the first and second broadsides 1410 and 1412. Similarly, each of the first and second broadsides 1410 and 1412 are connected between the first and second edges 1406 and 1408.

The edges 1406 and 1408 and broadsides 1410 and 1412 can define respective distances along a plane that is oriented normal to the contact body 1407. For instance, the edges 1406 and 1408 can each extend along a first distance from one of the first and second broadsides 1410 and 1412 to the other of the first and second broadsides 1410 and 1412 along the plane. The broadsides 1410 and 1412 can each extend along a second distance from one of the first and second edges 1406 and 1408 to the other of the first and second edges 1406 and 1408 along the plane. The second distance can be greater than the first distance. In one example, the first distance can define a thickness of the contact body 1407, and the second distance can define a width of the contact body 1407. The thickness along at least a portion of the contact body 1407 can be oriented along the transverse direction T, and the width along at least a portion of the contact body 1407 can be oriented along the lateral direction A.

The electrical contact 1144 includes an anchoring region 1414 that is configured to secure the electrical contact 1144 to the at least one insert mold body 1118 of the electrical connector 1100. The electrical contact 1144 further includes a contact beam 1416 that extends out with respect to the anchoring region 1414. For instance, the contact beam 1416 can extend out with respect to the anchoring region 1414 along the longitudinal direction L. In one example, the contact beam 1416 can extend from the anchoring region 1414.

The contact beam 816 has first and second sides 1416a and 1416b, and first and second faces 1416c and 1416d. The first and second sides 1416a and 1416b of the contact beam 1416 are defined by the first and second edges 1406 and 1408, respectively, of the contact body 1407. Similarly, the first and second faces 1416c and 1416d of the contact beam 1416 are defined by the first and second broadsides 1410 and 1412, respectively, of the contact body 1407. The contact beam 1416 can define a mating portion 1417 that is configured to mate with the second complementary electrical component 1300, and a stub 1419 that extends from the mating portion 1417 to a free end 1418 of the electrical contact 1144. The contact beam has a first beam portion that extends along a central axis CA, and a second beam portion that extends from the first beam portion towards the free end 1418 of the contact beam 1416 along a direction that is angularly offset from the central axis with respect to the lateral direction A.

The anchoring region 1414 extends between the mounting end 1402 and the contact beam 1416. For instance, the anchoring region 1414 can extend from the mounting end 1402 to the contact beam 1416. The anchoring region 1414 can define a maximum length L_max,2. Further, the anchoring region 1414 can be disposed partially or fully below a midpoint of the electrical contact 1144 along the longitudinal direction L. The contact beam 1416 extends between the free end 1418 of the electrical contact 1144 and the anchoring region 1414, such as from the free end 1418 to the anchoring region 1414, and has a maximum length L_max,3.

The anchoring region 1414 can be substantially planar as it extends from the mounting end 1402 to the contact beam 1416 along the longitudinal direction L. For instance, the broadsides 1410 and 1412 can be substantially planar along respective planes that are defined by the longitudinal direction L and the lateral direction A at the anchoring region 1414 from the mounting end 1412 to the contact beam 1416. Alternatively, the anchoring region 1414 can have a bent, such as a curved, shape between the mounting end 1402 and the contact beam 1416.

The anchoring region 1414 can include at least one portion that extends outward from one of the first and second edges 1406 and 1408 along the lateral direction A. At least a portion of the at least one of the first and second portions portion can be aligned with, or at least not extend outward from, the one of the first and second edges 1406 and 1408 of the contact body 1407 along the lateral direction A. For example, the at least one of the first and second portions can extend outward from the first edge 1406 along the lateral direction A, and can be aligned with, or at least not extend outward from, the second edge 1408 of the contact body 1407 along the lateral direction A.

The at least one of the first and second enlarged portion has first and second sides spaced from one another along the lateral direction A. At least a portion of the first side extends outward from the first edge 1406 of the first electrical contact 1144 along the lateral direction A and at least a portion of the second side extends up to the second edge 1408 of the first electrical contact 1144 along the lateral direction A. For example, at least a portion of the second side can extend inward from or can be aligned with the second edge 1408 of the first electrical contact 1144 along the lateral direction A.

The anchoring region 1414 can include at least one of a first portion, a second portion, and a third portion. The third portion can be between the first and second portions, and can thus be considered to be an intermediate portion. The intermediate portion can define a width along the lateral direction A that is less than the width of at least one or both of the first and second enlarged portions along the lateral direction A. In one example, one or both of the first and second portions can extend out from the contact body 1407. Thus, the intermediate portion can be considered to be a narrowed portion, and one or both of the first and second portions can be considered to be enlarged portions. For instance, at least one of the first and second portions can extend out from the first edge 1406 along the lateral direction A. In one example, the anchoring region 1414 can include a first portion 1420, an intermediate portion 1424, and a second portion 1426. The intermediate portion 1424 can be disposed between the first and second portions 1420 and 1426. One or more of the first portion 1420, the intermediate portion 1424, and the second portion 1426 can extend up to the second edge 1408 of the contact body 1407 with respect to the lateral direction A. For example, one or more of the first portion 1420, the intermediate portion 1424, and the second portion 1426 can extend inward of, or can be aligned with the second edge 1408 along the lateral direction A. In one example, the first portion 1420, the intermediate portion 1424, and the second portion 1426 can be substantially aligned along the second edge 1408.

The first portion 1420 can define first and second opposed outermost sides 1420a and 1420b. The outermost sides 1420a and 1420b can be spaced from each other along the lateral direction A. The first outermost side 1420a can be outwardly spaced from the first edge 1406 along the lateral direction A. The second outermost side 1420b can be aligned with, or at least not extend outward from, the second edge 1408. The first portion 1420 can have a width W₁ along the lateral direction A from the first outermost side 1420a to the second outermost side 1420b, the width W₁ being greater than a width W₂ of the broadsides 1410 and 1412 from the first edge 1406 to the second edge 1408. The first portion 1420 can extend between the contact beam 1416 and the mounting end 1402, such as from the contact beam 1416 towards the mounting end 1402. The first portion 1420 can have a substantially rectangular shape in a plane defined by the longitudinal and lateral directions as shown, or can have any other suitable shape in the plane such as a circle, square, or other polygon. Further, the first portion 1420 has a maximum length L_max,4. While the outermost side 1420a of the first portion 1420 can be spaced outwardly from the first edge 1406 with respect to the lateral direction A as described above, it should be appreciated that the outermost side 1420a can be aligned with the first edge 1406 as desired. Further, while the second side 1420b of the first portion 1420 can be aligned with the second edge 1408 as described above, it should be appreciated that the outermost side 1420b can extend inward from the second edge 1408 with respect to the lateral direction A. The first portion 1420 can extend out from at least one of the edges 1406 and 1408 along the lateral direction A. For instance, the first portion 1420 can extend out from the first edge 1406 of the contact beam 1416. Further, the first portion 1420 can be coplanar with the broadsides 1410 and 1412.

The first portion 1420 can define a body 1420c and at least one shoulder, such as a first upper shoulder 1420d that extends from the body 1420c to the contact body 1407, and in particular to the first edge 1406. It should be appreciated that the first upper shoulder 1420d can be omitted in some embodiments. The first upper shoulder 1420d can extend from the portion 1420 to the contact body 1407 along a direction having a directional component along the lateral direction A.

The intermediate portion 1424 can define opposed outermost sides 1424a and 1424b. The outermost sides 1424a and 1424b can be spaced from each other along the lateral direction A. In one example, the intermediate portion defines a width W₃ from one of the outermost sides 1424a and 1424b to the other of the outermost sides 1424a and 1424b. The width W₃ of the intermediate portion 1424 can be less than the corresponding width of one or both of the portions 1420 and 1426. In some embodiments, the width W₃ of the intermediate portion 1424 can be less than the width W₂ of the broadsides 1410 and 1412 from one of the edges 1406 and 1408 to the other of the edges 1406 and 1408. Alternatively, the width W₃ of the intermediate portion 1424 can be greater than the width of the broadsides 1410 and 1412. Alternatively still, the outermost sides 1424a and 1424b can be aligned with the first and second edges 1406 and 1408, respectively. Thus, the width W₃ of the intermediate portion 1424 can be substantially equal to the width W₂ of the broadsides 1410 and 1412.

The intermediate portion 1424 can extend between the first portion 1420 and the mounting end 1402 along the longitudinal direction L. For instance, the intermediate portion 1424 can extend from the first portion 1420 toward the mounting end 1402. The intermediate portion 1424 can define a maximum length L_max,5 along the longitudinal direction L. The intermediate portion 1424 can have a substantially rectangular shape in a plane defined by the longitudinal and lateral directions as shown, or can have any other suitable shape in the plane such as a circle, square, or other polygon. Further, the first outermost side 1424a can be linear as it extends from the first portion 1420 towards the mounting end 1402. Similarly, the second outermost side 1424b can be linear as it extends from the first portion 1420 towards the mounting end 1402. Alternatively, one or both of the first and second outermost sides 1424a and 1424b can be curved between the first portion 1420 and the mounting end 1402. For example, one or both of the first and second outermost sides 1424a and 1424b can be concave between the first portion 1420 and the mounting end 1402. As shown, the intermediate portion 1424 of the electrical contact 1144 can be elongate along the longitudinal direction L as it extends between the first portion 1420 and the mounting end 1402, such that the maximum length L_max,5 of the intermediate portion 1424 is greater than each of the width W₃ of the intermediate portion 1424 along the lateral direction A and the thickness of the intermediate portion 1424 along the transverse direction T.

The first portion 1420 can define at least one lower shoulder, such as a first lower shoulder 1420e that extends from the body 1420c of the first portion 1420 to the intermediate portion 1424. For instance, the first lower shoulder 1420e can extend from the outermost side 1420a to the outermost side 1424a. It should be appreciated that the first lower shoulder 1420e can be omitted in some embodiments. The lower shoulder 1420e can extend from the portion 1420 to the intermediate portion 1426 along a direction having a directional component along the lateral direction A. Further, the lower shoulder 1420e can face away from the upper shoulder 1420d.

The second portion 1426 can define first and second opposed outermost sides 1426a and 1426b. The outermost sides 1426a and 1426b can be spaced from each other along the lateral direction A. The first outermost side 1426a can be outwardly spaced from the first side 1424a of the intermediate portion 1424 along the lateral direction A. The first outermost side 1426a can also be outwardly spaced from one or more of the first side 1420a of the first portion 1420 and the first edge 1406 along the lateral direction A. The second outermost side 1426b can extend inwardly from or can be aligned with one or more of the second outermost side 1424b of the intermediate portion 1424, the second outermost side 1420b of the first portion 1420, and the second edge 1408.

The second portion 1426 can have a width W₄ along the lateral direction A from the first outermost side 1426a to the second outermost side 1426b, the width W₄ being greater than the width W₂ of the broadsides 1410 and 1412 from the first edge 1406 to the second edge 1408. The second portion 1426 can extend between the contact beam 1416 and the mounting end 1402, such as from the mounting end 1402 towards the contact beam 1416. The second portion 1426 can have a substantially rectangular shape in a plane defined by the longitudinal and lateral directions as shown, or can have any other suitable shape in the plane such as a circle, square, or other polygon. Further, the second portion 1426 has a maximum length L_max,6. While the outermost side 1426a of the second portion 1426 can be spaced outwardly from the first side 1426a with respect to the lateral direction A as described above, it should be appreciated that the outermost side 1426a can be aligned with the outermost side 1424a as desired. Further, while the second side 1426b of the second portion 1426 can be aligned with the second side 1424b or the second edge 1408 as described above, it should be appreciated that the second side 1426b can extend up to one or more of the second side 1420b, the second side 1424b, and the second edge 1408. The second portion 1426 can extend outward from one or more of the first side 1420a of the first portion 1420, the first side 1426a of the intermediate portion 1424, and the first edge 1406 along the lateral direction A. Further, the second portion 1426 can be coplanar with the broadsides 1410 and 1412.

The second portion 1426 can define a body 1426c and at least one shoulder, such as a first upper shoulder 1426d that extends from the body 1426c to the intermediate portion 1424, and in particular to the first side 1424a of the intermediate portion 1424. It should be appreciated that the first upper shoulder 1426d can be omitted in some embodiments. The upper shoulder 1426d can extend from the portion 1426 to the intermediate portion 1424 along a direction having a directional component along the lateral direction A. Further, the upper shoulder 1426c can face the lower shoulder 1420e of the first portion 1420.

The second portion 1426 can define at least one lower shoulder, such as a first lower shoulder 1426e that extends from the body 1426c of the second portion 1426 to the mounting tail 1434. For instance, the first lower shoulder 1426e can extend from the outermost side 1426a to the mounting tail 1434. The second portion 1426 can also define a second lower shoulder 1426e that extends from the body 1426c of the second portion 1426 to the mounting tail 1434. For instance, the second lower shoulder 1426e can extend from the outermost side 1426b to a corresponding side of the mounting tail 1434. It should be appreciated that one or both of the first and second lower shoulders 1426e can be omitted in some embodiments. Each lower shoulder 1426e can extend from the portion 1426 to the mounting tail 1434 along a direction having a directional component along the lateral direction A. Further, each the first lower shoulder 1426e can face away from the first upper shoulder 1426d. The first lower shoulder 1420e of the first portion 1420 and the first upper shoulder 1426d of the second portion 1426 together can provide two locations of mechanical support that retains the electrical contact in the insert mold body.

The contact beam 1416 can be constructed as a flexible beam having a bent, such as curved, shape that extends from a free end 1418 of the electrical contact 1144 towards the anchoring region 1414. Bent structures as described herein refer to bent shapes that can be fabricated, for instance, by bending the end or by stamping a bent shape, or by any other suitable manufacturing process. The first broadside 1410 at the contact beam 1416 is configured to wipe against the second complementary electrical component 1300 as the component is mated with the contact beam 1416 along the longitudinal direction L. Further, the contact beam 1416 is configured to contact the second complementary electrical component 1300 so as to apply a force to a surface of the complementary electrical component 1300 along the transverse direction T.

The contact beam 1416 can include at least a first transverse bend region 1430 between the anchoring region 1414 and the mating end 1404. The first transverse bend region 1430 can curve towards a first transverse direction that extends from the second broadside 1412 toward the first broadside 1410 as the contact beam 1416 extends away from the anchoring region 1414 along the longitudinal direction L. The contact beam 1416 can further include at least a second transverse bend region 1432 that is between the first transverse bend region 1430 and the mating end 1404. The second transverse bend region 1432 can curve towards a second transverse direction, opposite the first transverse direction, that extends from the first broadside 1410 toward the second broadside 1412 as the contact beam 1416 extends away from the first transverse bend region 1430 along the longitudinal direction L. In alternative embodiments, the curvature of the contact beam 1416 can vary from that shown. For example, the contact beam 1416 can include as few as one transverse bend region, or greater than transverse two bend regions.

The contact beam 1416 can include at least a first lateral bend region 1438 between the anchoring region 1414 and the mating end 1404. The first lateral bend region 1438 can curve towards the lateral direction as the contact beam 1416 extends away from the anchoring region 1414 along the longitudinal direction L. For example, the first lateral bend region 1438 can curve towards a first lateral direction that extends from the second edge 1408 toward the first edge 1406 as the contact beam 1416 extends away from the anchoring region 1414 along the longitudinal direction L. The contact beam 1416 can further include at least a second lateral bend region 1440 that is between the first lateral bend region 1438 and the mating end 1404. For example, the second lateral bend region 1440 can curve towards the lateral direction as the contact beam 1416 extends away from the first lateral bend region 1438 along the longitudinal direction L. The second lateral bend region 1440 can curve towards a second lateral direction, opposite the first lateral direction, that extends from the first edge 1406 toward the second edge 1408 as the contact beam 1416 extends away from the first lateral bend region 1438 along the longitudinal direction L. In alternative embodiments, the curvature of the contact beam 1416 can vary from that shown. For example, the contact beam 1416 can include as few as one lateral bend region, or greater than two lateral bend regions.

The anchoring region 1414 can define a central axis CA that extends in the longitudinal direction between the first and second broadsides 1410 and 1412. The second transverse bend region 1432 can extend at least partially on a first side of the central axis CA with respect to the transverse direction T, the first side being spaced from the central axis CA along a direction that is opposite the second broadside 1412. Further, the free end 1418 can be positioned on a second side of the central axis CA with respect to the transverse direction T, the second side being spaced from the central axis CA along a direction that is opposite the first broadside 1410.

The mounting end 1402 can include a mounting tail 1434 that extends away from the anchoring region 1414. For example, the mounting tail 1434 can define a surface-mount tail as shown that is bent, or otherwise curved, outward from the anchoring region 1414 along the transverse direction T, such as along a direction that extends from the first broadside 1410 towards the second broadside 1412. Thus, the mounting tail 1434 can be disposed on the same side of the central axis CA as the free end 1418 with respect to the transverse direction T as shown in FIG. 22. Alternatively, the mounting tail 1434 can extend on the opposite side of the central axis CA as the free end 1418. The mounting tail 1434 defines a terminal end 1436 of the electrical contact 1144. The terminal end 1436 can be configured as a mounting surface that mounts onto, such as abuts, an electrical contact of the first complementary electrical component 1300. The mounting surface can substantially face the longitudinal direction L, such as in a direction away from the free end 1418 of the electrical contact. Thus, the mounting surface can be configured to mount onto a complementary electrical component that lies in a plane that is substantially perpendicular to the longitudinal direction L. In alternative embodiments, the mounting tail 1434 can be configured as a differently-configured surface-mount tail, as a press-fit tail, as a fusible element such as a solder ball, or combinations thereof.

The electrical contact 1144 defines maximum length L_max,1 along the longitudinal direction L from the free end 1418 to the terminal end 1436. The electrical contact 1144 can further define a maximum width W_max along the lateral direction A. The maximum width W_max can be equal to at least one of the width W₁ of the first portion 1420 and the width W₄ of the second portion 1426, such as a larger of the widths W₁ and W₄. Alternatively, the maximum width W_max can be equal to both the width W₁ of the first portion 1420 and the width W₄ of the second portion 1426 when the widths W₁ and W₄ are equal. The contact body 1407 yet further defines a maximum thickness T_max along the transverse direction T from one of the opposed broadsides 1410 and 1412 to the other. The maximum length L_max,1 of the electrical contact 1144 can be greater than both the maximum width W_max and the maximum thickness T_max. Further, the maximum width W_max of the electrical contact 1144 can be greater than the maximum thickness T_max. Thus, the electrical contact 1144 can be said to be elongate along the longitudinal direction L.

Turning now to FIGS. 24 to 26, the second electrical contact 1146 of each pair 1142 can be a substantial mirror image of the first electrical contact 1144 taken about a line that extends substantially along the longitudinal direction. The second electrical contact 1146 of each pair 1142 can include a mounting end 1502, and a mating end 1504 opposite the mounting end 1502 along the longitudinal direction L. The mounting end 1502 is configured to be mounted onto, for example, the first complementary electrical component 1200 along a mounting direction. The mating end 1504 is configured to mate with, for example, the second complementary electrical component 1300 along a mating direction. In one example, the mating direction and mounting direction can be oriented along the same direction. For instance, the mating direction and mounting direction can be oriented along the longitudinal direction L. Thus, the second electrical contact 1146 is considered to be a vertical electrical contact. Alternatively, the second electrical contact 1146 can be configured as a right-angle contact, whereby the mating direction and the mounting direction are oriented substantially perpendicular to each other. For instance, when the electrical contact 1146 is configured as a right-angle contact, the mounting end 1502 can be oriented along the longitudinal direction L, and the mating end 1504 can be oriented along the transverse direction T.

The electrical contact 1146 includes a contact body 1507 that defines first and second edges 1506 and 1508, and first and second broadsides 1510 and 1512. The first and second edges 1506 and 1508 are spaced opposite from one another along the lateral direction A. Thus, the first and second edges 1506 and 1508 can face away from one another. At least respective portions of the first and second broadsides 1510 and 1512 can be spaced opposite each other along the transverse direction T. Thus, the first and second broadsides 1510 and 1512 can face away from one another. It should therefore be appreciated that each of the first and second edges 1506 and 1508 are connected between the first and second broadsides 1510 and 1512. Similarly, each of the first and second broadsides 1510 and 1512 are connected between the first and second edges 1506 and 1508.

The edges 1506 and 1508 and broadsides 1510 and 1512 can define respective distances along a plane that is oriented normal to the contact body 1507. For instance, the edges 1506 and 1508 can each extend along a first distance from one of the first and second broadsides 1510 and 1512 to the other of the first and second broadsides 1510 and 1512 along the plane. The broadsides 1510 and 1512 can each extend along a second distance from one of the first and second edges 1506 and 1508 to the other of the first and second edges 1506 and 1508 along the plane. The second distance can be greater than the first distance. In one example, the first distance can define a thickness of the contact body 1507, and the second distance can define a width of the contact body 1507. The thickness along at least a portion of the contact body 1507 can be oriented along the transverse direction T, and the width along at least a portion of the contact body 1507 can be oriented along the lateral direction A.

The electrical contact 1146 includes an anchoring region 1514 that is configured to secure the electrical contact 1146 to the at least one insert mold body 1118 of the electrical connector 1100. The electrical contact 1146 further includes a contact beam 1516 that extends out with respect to the anchoring region 1514. For instance, the contact beam 1516 can extend out with respect to the anchoring region 1514 along the longitudinal direction L. In one example, the contact beam 1516 can extend from the anchoring region 1514.

The contact beam 1516 has first and second sides 1516a and 1516b, and first and second faces 1516c and 1516d. The first and second sides 1516a and 1516b of the contact beam 1516 are defined by the first and second edges 1506 and 1508, respectively, of the contact body 1507. Similarly, the first and second faces 1516c and 1516d of the contact beam 1516 are defined by the first and second broadsides 1510 and 1512, respectively, of the contact body 1507. The contact beam 1516 can define a mating portion 1517 that is configured to mate with the second complementary electrical component 1300, and a stub 1519 that extends from the mating portion 1517 to a free end 1518 of the electrical contact 1146. The contact beam 1516 has a first beam portion that extends along a central axis CA, and a second beam portion that extends from the first beam portion towards the free end 1518 of the contact beam 1516 along a direction that is angularly offset from the central axis with respect to the lateral direction A.

The anchoring region 1514 extends between the mounting end 1502 and the contact beam 1516. For instance, the anchoring region 1514 can extend from the mounting end 1502 to the contact beam 1516. The anchoring region 1514 can define a maximum length L_max,2. Further, the anchoring region 1514 can be disposed partially or fully below a midpoint of the electrical contact 1146 along the longitudinal direction L. The contact beam 1516 extends between the free end 1518 of the electrical contact 1146 and the anchoring region 1514, such as from the free end 1518 to the anchoring region 1514, and has a maximum length L_max,3.

The anchoring region 1514 can be substantially planar as it extends from the mounting end 1502 to the contact beam 1516 along the longitudinal direction L. For instance, the broadsides 1510 and 1512 can be substantially planar along respective planes that are defined by the longitudinal direction L and the lateral direction A at the anchoring region 1514 from the mounting end 1512 to the contact beam 1516. Alternatively, the anchoring region 1514 can have a bent, such as a curved, shape between the mounting end 1502 and the contact beam 1516.

The anchoring region 1514 can include at least one enlarged portion that extends outward from one of the first and second edges 1506 and 1508 along the lateral direction A. At least a portion of the at least one enlarged portion can be aligned with, or at least not extend outward from, the one of the first and second edges 1506 and 1508 of the contact body 1507 along the lateral direction A. For example, the at least one enlarged portion can extend outward from the second edge 1508 along the lateral direction A, and can be aligned with, or at least not extend outward from, the first edge 1506 of the contact body 1507 along the lateral direction A.

The at least one enlarged portion has first and second sides spaced from one another along the lateral direction A. At least a portion of the second side extends outward from the second edge 1508 of the second electrical contact 1146 along the lateral direction A and at least a portion of the first side extends up to the first edge 1506 of the second electrical contact 1146 along the lateral direction A. For example, at least a portion of the first side can extend inward from or can be aligned with the first edge 1506 of the second electrical contact 1146 along the lateral direction A.

The anchoring region 1514 can include at least one of a first portion, a second portion, and a third portion. The third portion can be disposed between the first and second portions, and thus can be considered to be an intermediate portion. The intermediate portion can define a width along the lateral direction A that is less than the width of at least one or both of the first and second portions along the lateral direction A. Thus, the intermediate portion can be considered to be a intermediate portion, and one or both of the first and second portions can be considered to be enlarged portions. In one example, one or both of the first and second portions can extend out from the contact body 1507. For instance, at least one of the first and second portions can extend out from the second edge 1508 along the lateral direction A. In one example, the anchoring region 1514 can include a first portion 1520, an intermediate portion 1524, and a second portion 1526. The intermediate portion 1524 can be disposed between the first and second portions 1520 and 1526. One or more of the first portion 1520, the intermediate portion 1524, and the second portion 1526 can extend up to the first edge 1506 of the contact body 1507 along the lateral direction A. Thus, one or more of the first portion 1520, the intermediate portion 1524, and the second portion 1526 can extend inward from, or can be aligned with, the first edge 1506. In one example, the first portion 1520, the intermediate portion 1524, and the second portion 1526 can be aligned with the first edge 1506 such that they are all substantially aligned along the first edge 1506.

The first portion 1520 can define opposed outermost sides 1520a and 1520b. The outermost sides 1520a and 1520b can be spaced from each other along the lateral direction A. The second outermost side 1520b can be outwardly spaced from the second edge 1508 along the lateral direction A. The first outermost side 1520a can be extend inward from or can be aligned with the first edge 1506 along the lateral direction. The first portion 1520 can have a width W₁ along the lateral direction A from the first outermost side 1520a to the second outermost side 1520b, the width W₁ being greater than a width W₂ of the broadsides 1510 and 1512 from the first edge 1506 to the second edge 1508. The first portion 1520 can extend between the contact beam 1516 and the mounting end 1502, such as from the contact beam 1516 towards the mounting end 1502. The first portion 1520 can have a substantially rectangular shape in a plane defined by the longitudinal and lateral directions as shown, or can have any other suitable shape in the plane such as a circle, square, or other polygon. Further, the first portion 1520 has a maximum length L_max,4. While the second side 1520b of the first portion 1520 can be spaced outwardly from the second edge 1508 with respect to the lateral direction A as described above, it should be appreciated that the second side 1520b can be aligned with the second edge 1508 as desired. Further, while the first side 1520a of the first portion 1520 can be aligned with the first edge 1506 as described above, it should be appreciated that the first side 1520a can extend inward from the first edge 1506. Further, the first portion 1520 can be coplanar with the broadsides 1510 and 1512.

The first portion 1520 can define a body 1520c and at least one shoulder, such as a first upper shoulder 1520d that extends from the body 1520c to the contact body 1507, and in particular to the second edge 1508. It should be appreciated that the first upper shoulder 1520d can be omitted in some embodiments. The first upper shoulder 1520d can extend from the portion 1520 to the contact body 1507 along a direction having a directional component along the lateral direction A.

The intermediate portion 1524 can define first and second opposed outermost sides 1524a and 1524b. The outermost sides 1524a and 1524b can be spaced from each other along the lateral direction A. In one example, the intermediate portion defines a width W₃ from one of the outermost sides 1524a and 1524b to the other of the outermost sides 1524a and 1524b. The width W₃ of the intermediate portion 1524 can be less than the corresponding width of one or both of the portions 1520 and 1526. For instance, the width W₃ of the intermediate portion 1524 can be less than the width of the broadsides 1510 and 1512 from one of the edges 1506 and 1508 to the other of the edges 1506 and 1508. Alternatively, the width W₃ of the intermediate portion 1524 can be greater than the width of the broadsides 1510 and 1512. Alternatively still, the outermost sides 1524a and 1524b can be aligned with the first and second edges 1506 and 1508, respectively. Thus, the width W₃ of the intermediate portion 1524 can be substantially equal to the width of the broadsides 1510 and 1512.

The intermediate portion 1524 can extend between the first portion 1520 and the mounting end 1502 along the longitudinal direction L. For instance, the intermediate portion 1524 can extend from the first portion 1520 toward the mounting end 1502. The intermediate portion 1524 can define a maximum length L_max,5 along the longitudinal direction L. The intermediate portion 1524 can have a substantially rectangular shape in a plane defined by the longitudinal and lateral directions as shown, or can have any other suitable shape in the plane such as a circle, square, or other polygon. Further, the first outermost side 1524a can be linear as it extends from the first portion 1520 towards the mounting end 1502. Similarly, the second outermost side 1524b can be linear as it extends from the first portion 1520 towards the mounting end 1502. Alternatively, one or both of the first and second outermost sides 1524a and 1524b can be curved between the first portion 1520 and the mounting end 1502. For example, one or both of the first and second outermost sides 1524a and 1524b can be concave between the first portion 1520 and the mounting end 1502. As shown, the intermediate portion 1524 of the electrical contact 1146 can be elongate along the longitudinal direction L as it extends between the first portion 1520 and the mounting end 1502, such that the maximum length L_max,5 of the intermediate portion 1524 is greater than each of the width W₃ of the intermediate portion 1524 along the lateral direction A and the thickness of the intermediate portion 1524 along the transverse direction T.

The first portion 1520 can define at least one lower shoulder, such as a first lower shoulder 1520e that extends from the body 1520c of the first portion 1520 to the intermediate portion 1524. For instance, the first lower shoulder 1520e can extend from the second outermost side 1520b to the second outermost side 1524b. It should be appreciated that the first lower shoulder 1520e can be omitted in some embodiments. The lower shoulder 1520e can extend from the portion 1520 to the intermediate portion 1526 along a direction having a directional component along the lateral direction A. Further, the lower shoulder 1520e can face away from the upper shoulder 1520d.

The second portion 1526 can define first and second opposed outermost sides 1526a and 1526b. The outermost sides 1526a and 1526b can be spaced from each other along the lateral direction A. The second outermost side 1526b can be outwardly spaced from the second side 1524b of the intermediate portion 1524 along the lateral direction A. The outermost side 1526b can also be outwardly spaced from the second edge 1508 along the lateral direction A. The first outermost side 1526a can extend up to one or more of the first outermost side 1524a of the intermediate portion 1524 and the first outermost side 1520a of the first portion 1520, and the first edge 1506 along the lateral direction A. For example, the first outermost side 1526a can extend inward from, or can be aligned with, one or more of the first outermost side 1524a of the intermediate portion 1524, the first outermost side 1520a of the first portion 1520, and the first edge 1506.

The second portion 1526 can have a width W₄ along the lateral direction A from the first outermost side 1526a to the second outermost side 1526b, the width W₄ being greater than the width W₂ of the broadsides 1510 and 1512 from the first edge 1506 to the second edge 1508. The second portion 1526 can extend between the contact beam 1516 and the mounting end 1502, such as from the mounting end 1502 towards the contact beam 1516. The second portion 1526 can have a substantially rectangular shape in a plane defined by the longitudinal and lateral directions as shown, or can have any other suitable shape in the plane such as a circle, square, or other polygon. Further, the second portion 1526 has a maximum length L_max,6. While the second outermost side 1526b of the second portion 1526 can be spaced outwardly from the second side 1524b with respect to the lateral direction A as described above, it should be appreciated that the second outermost side 1526b can be aligned with the second outermost side 1524b as desired. Further, while the first outermost side 1526a of the second portion 1526 can be aligned with the outermost side 1524a or the first edge 1506 as described above, it should be appreciated that the outermost side 1526a can extend up to one or more of the first outermost side 1524a of the intermediate portion 1524, the first outermost side 1520a of the first portion 1520, and the first edge 1506. The second portion 1526 can be coplanar with the broadsides 1510 and 1512.

The second portion 1526 can define a body 1526c and at least one shoulder, such as a first upper shoulder 1526d that extends from the body 1526c to the intermediate portion 1524, and in particular to the second side 1524b of the intermediate portion 1524. It should be appreciated that the first upper shoulder 1526d can be omitted in some embodiments. The upper shoulder 1526d can extend from the portion 1526 to the intermediate portion 1524 along a direction having a directional component along the lateral direction A. Further, the upper shoulder 1526c can face the lower shoulder 1520e of the first portion 1520.

The second portion 1526 can define at least one lower shoulder, such as a first lower shoulder 1526e that extends from the body 1526c of the second portion 1526 to the mounting tail 1534. For instance, the first lower shoulder 1526e can extend from the outermost side 1526b to the mounting tail 1534. The second portion 1526 can also define a second lower shoulder 1526e that extends from the body 1526c of the second portion 1526 to the mounting tail 1534. For instance, the second lower shoulder 1526e can extend from the outermost side 1526a to a corresponding side of the mounting tail 1534. It should be appreciated that one or both of the first and second lower shoulders 1526e can be omitted in some embodiments. Each lower shoulder 1526e can extend from the portion 1526 to the mounting tail 1534 along a direction having a directional component along the lateral direction A. Further, each the first lower shoulder 1526e can face away from the first upper shoulder 1526d. The first lower shoulder 1520e of the first portion 1520 and the first upper shoulder 1526d of the second portion 1526 together can provide two locations of mechanical support that retains the electrical contact in the insert mold body 1118.

The contact beam 1516 can be constructed as a flexible beam having a bent, such as curved, shape that extends from the anchoring region 1514 to a free end 1518 of the electrical contact 1146. Bent structures as described herein refer to bent shapes that can be fabricated, for instance, by bending the end or by stamping a bent shape, or by any other suitable manufacturing process. The first broadside 1510 at the contact beam 1516 is configured to wipe against the second complementary electrical component 1300 as the component is mated with the contact beam 1516 along the longitudinal direction L. Further, the contact beam 1516 is configured to contact the second complementary electrical component 1300 so as to apply a force to a surface of the complementary electrical component 1300 along the transverse direction T.

The contact beam 1516 can include at least a first transverse bend region 1517 between the anchoring region 1514 and the mating end 1504. The first transverse bend region 1517 can curve towards a first transverse direction that extends from the second broadside 1512 toward the first broadside 1510 as the contact beam 1516 extends away from the anchoring region 1514 along the longitudinal direction L. The contact beam 1516 can further include at least a second transverse bend region 1532 that is between the first transverse bend region 1517 and the mating end 1504. The second transverse bend region 1532 can curve towards a second transverse direction, opposite the first transverse direction, that extends from the first broadside 1510 toward the second broadside 1512 as the contact beam 1516 extends away from the first transverse bend region 1517 along the longitudinal direction L. In alternative embodiments, the curvature of the contact beam 1516 can vary from that shown. For example, the contact beam 1516 can include as few as one transverse bend region, or greater than transverse two bend regions.

The contact beam 1516 can include at least a first lateral bend region 1538 between the anchoring region 1514 and the mating end 1504. The first lateral bend region 1538 can curve towards the lateral direction as the contact beam 1516 extends away from the anchoring region 1514 along the longitudinal direction L. For example, the first lateral bend region 1538 can curve towards the second lateral direction that extends from the first edge 1506 toward the second edge 1508 as the contact beam 1516 extends away from the anchoring region 1514 along the longitudinal direction L. The contact beam 1516 can further include at least a second lateral bend region 1540 that is between the first lateral bend region 1538 and the mating end 1504. The second lateral bend region 1540 can curve towards the lateral direction as the contact beam 1516 extends away from the first lateral bend region 1538 along the longitudinal direction L. For example, the second lateral bend region 1540 can curve towards the first lateral direction, opposite the second lateral direction, that extends from the second edge 1508 toward the first edge 1506 as the contact beam 1516 extends away from the first lateral bend region 1538 along the longitudinal direction L. In alternative embodiments, the curvature of the contact beam 1516 can vary from that shown. For example, the contact beam 1516 can include as few as one lateral bend region, or greater than two lateral bend regions.

The anchoring region 1514 can define a central axis CA that extends in the longitudinal direction between the first and second broadsides 1510 and 1512. The second transverse bend region 1532 can extend at least partially on a first side of the central axis CA with respect to the transverse direction T, the first side being spaced from the central axis CA along a direction that is opposite the second broadside 1512. Further, the free end 1518 can be positioned on a second side of the central axis CA with respect to the transverse direction T, the second side being spaced from the central axis CA along a direction that is opposite the first broadside 1510.

The mounting end 1502 can include a mounting tail 1534 that extends away from the anchoring region 1514. For example, the mounting tail 1534 can define a surface-mount tail as shown that is bent, or otherwise curved, outward from the anchoring region 1514 along the transverse direction T, such as along a direction that extends from the first broadside 1510 towards the second broadside 1512. Thus, the mounting tail 1534 can be disposed on the same side of the central axis CA as the free end 1518 with respect to the transverse direction T as shown in FIG. 25. Alternatively, the mounting tail 1534 can extend on the opposite side of the central axis CA as the free end 1518. The mounting tail 1534 defines a terminal end 1536 of the electrical contact 1146. The terminal end 1536 can be configured as a mounting surface that mounts onto, such as abuts, an electrical contact of the first complementary electrical component 1300. The mounting surface can substantially face the longitudinal direction L, such as in a direction away from the free end 1518 of the electrical contact. Thus, the mounting surface can be configured to mount onto a complementary electrical component that lies in a plane that is substantially perpendicular to the longitudinal direction L. In alternative embodiments, the mounting tail 1534 can be configured as a differently-configured surface-mount tail, as a press-fit tail, as a fusible element such as a solder ball, or combinations thereof.

The electrical contact 1146 defines maximum length L_max,1 along the longitudinal direction L from the free end 1518 to the terminal end 1536. The electrical contact 1146 can further define a maximum width W_max along the lateral direction A. The maximum width W_max can be equal to at least one of the width W₁ of the first portion 1520 and the width W₄ of the second portion 1526, such as a larger of the widths W₁ and W₄. Alternatively, the maximum width W_max can be equal to both the width W₁ of the first portion 1520 and the width W₄ of the second portion 1526 when the widths W₁ and W₄ are equal. The contact body 1507 yet further defines a maximum thickness T_max along the transverse direction T from one of the opposed broadsides 1510 and 1512 to the other. The maximum length L_max,1 of the electrical contact 1146 can be greater than both the maximum width W_max and the maximum thickness T_max. Further, the maximum width W_max of the electrical contact 1146 can be greater than the maximum thickness T_max. Thus, the electrical contact 1146 can be said to be elongate along the longitudinal direction L.

Turning now to FIGS. 27 to 29, each electrical contact 1152 of the second set 1150 can be substantially similar to the electrical contacts 1144 and 1146 of the first set 1140 with a few exceptions. For example, in at least some embodiments, each electrical contact 1152 can have first and second portions 1620 and 1626 that extend out on both sides, rather than on a single side. Further, in at least some embodiments, each electrical contact 1152 can have dimensions that vary from those of the electrical contacts 1144 and 1146.

Each electrical contact 1152 of the second set 1150 can each include a mounting end 1602, and a mating end 1604 opposite the mounting end 1602 along the longitudinal direction L. The mounting end 1602 is configured to be mounted onto, for example, the first complementary electrical component 1200 along a mounting direction. The mating end 1604 is configured to mate with, for example, the second complementary electrical component 1300 along a mating direction. In one example, the mating direction and mounting direction can be oriented along the same direction. For instance, the mating direction and mounting direction can be oriented along the longitudinal direction L. Thus, the electrical contact 1152 is considered to be a vertical electrical contact. Alternatively, the electrical contact 1152 can be configured as a right-angle contact, whereby the mating direction and the mounting direction are oriented substantially perpendicular to each other. For instance, when the electrical contact 1152 is configured as a right-angle contact the mating end 1604 can be oriented along the longitudinal direction L, and the mounting end 1602 can be oriented along the transverse direction T.

The electrical contact 1152 includes a contact body 1607 that defines first and second edges 1606 and 1608, and first and second broadsides 1610 and 1612. The first and second edges 1606 and 1608 are spaced opposite from one another along the lateral direction A. Thus, the first and second edges 1606 and 1608 can face away from one another. At least respective portions of the first and second broadsides can be spaced opposite each other along the transverse direction T. Thus, the first and second broadsides 1610 and 1612 can face away from one another. It should therefore be appreciated that each of the first and second edges 1606 and 1608 are connected between the first and second broadsides 1610 and 1612. Similarly, each of the first and second broadsides 1610 and 1612 are connected between the first and second edges 1606 and 1608. The edges 1606 and 1608 and broadsides 1610 and 1612 can define respective distances along a plane that is oriented normal to the contact body 1607. For instance, the edges 1606 and 1608 can each extend along a first distance from one of the first and second broadsides 1610 and 1612 to the other of the first and second broadsides 1610 and 1612 along the plane. The broadsides 1610 and 1612 can each extend along a second distance from one of the first and second edges 1606 and 1608 to the other of the first and second edges 1606 and 1608 along the plane. The second distance can be greater than the first distance. In one example, the first distance can define a thickness of the contact body 1607, and the second distance can define a width of the contact body 1607. The thickness along at least a portion of the contact body 1607 can be oriented along the transverse direction T, and the width along at least a portion of the contact body 1607 can be oriented along the lateral direction A.

The electrical contact 1152 includes an anchoring region 1614 that is configured to secure the electrical contact 1152 to the connector housing 1102 of the electrical connector 1100. The electrical contact 1152 further includes a contact beam 1616 that extends out with respect to the anchoring region 1614. For instance, the contact beam 1616 can extend out with respect to the anchoring region 1614 along the longitudinal direction L. In one example, the contact beam 1616 can extend from the anchoring region 1614.

The contact beam 1616 has first and second sides 1616a and 1616b, and first and second faces 1616c and 1616d. The first and second sides 1616a and 1616b of the contact beam 1616 are defined by the first and second edges 1606 and 1608, respectively, of the contact body 1607. Similarly, the first and second faces 1616c and 1616d of the contact beam 1616 are defined by the first and second broadsides 1610 and 1612, respectively, of the contact body 1607. The contact beam 1616 can define a mating portion 1617 that is configured to mate with the second complementary electrical component 1300, and a stub 1619 that extends from the mating portion 1617 to the free end 1618. The anchoring region 1614 extends between the mounting end 1602 and the contact beam 1616. For instance, the anchoring region 1614 can extend from the mounting end 1602 to the contact beam 1616.

The anchoring region 1614 can define a maximum length L_max,2. Further, the anchoring region 1614 can be disposed partially or fully below a midpoint of the electrical contact 1152 along the longitudinal direction L. The contact beam 1616 extends between a free end 1618 of the electrical contact 1618 and the anchoring region 1614, such as from the free end 1618 to the anchoring region 1614, and has a maximum length L_max,3. One or more up to all of the maximum lengths of the electrical contact 1152 can be different than the corresponding one or more up to all of the maximum lengths of the electrical contacts 1144 and 1146 as described in further detail below.

The anchoring region 1614 can be substantially planar as it extends from the mounting end 1602 to the contact beam 1616 along the longitudinal direction L. For instance, the broadsides 1610 and 1612 can be substantially planar along respective planes that are defined by the longitudinal direction L and the lateral direction A at the anchoring region 1614 from the mounting end 1612 to the contact beam 1616. Similarly, the edges 1606 and 1608 can be substantially planar along respective planes that are defined by the longitudinal direction L and the transverse direction at the anchoring region 1614 from the mounting end 1612 to the contact beam 1616. Alternatively, the anchoring region 1614 can have a bent, such as a curved, shape between the mounting end 1602 and the contact beam 1616.

The anchoring region 1614 can include at least one of first portion, a second portion, and a third portion. The third portion can be disposed between the first and second portions, and thus can be considered to be an intermediate portion. The third portion can define a width along the lateral direction A that is less than the width of at least one or both of the first and second enlarged portions along the lateral direction A. Thus, the third portion can be considered to be a narrowed portion and one or both of the first and second portions can be considered to be enlarged portions. In one example, one or both of the first and second portions can extend out from the contact body 1607. For instance, at least one of the first and second portions can extend out from one or both of the edges 1606 and 1608 along the lateral direction A. In one example, the anchoring region 1614 can include a first portion 1620, an intermediate portion 1624, and a second portion 1626. The intermediate portion 1624 can be disposed between the first and second portions 1620 and 1626. In one example, the intermediate portion 1624 can be defined by one or both of the edges 1606 and 1608 of the contact body 1607.

The first portion 1620 can define first and second opposed outermost sides 1620a and 1620b. The outermost sides 1620a and 1620b can be spaced from each other along the lateral direction A. The outermost sides 1620a and 1620b can be outwardly spaced from the respective first and second edges 1606 and 1608 along the lateral direction A. The first portion 1620 can have a width W₁ along the lateral direction A from the first outermost side 1620a to the second outermost side 1620b, the width W₁ being greater than the width W₂ of the broadsides 1610 and 1612 from the first edge 1606 to the second edge 1608. The first portion 1620 can extend between the contact beam 1616 and the mounting end 1602, such as from the contact beam 1616 towards the mounting end 1602. The first portion 1620 can have a substantially rectangular shape in a plane defined by the longitudinal and lateral directions as shown, or can have any other suitable shape in the plane such as a circle, square, or other polygon. Further, the first portion 1620 has a maximum length L_max,4. While the outermost sides 1620a and 1620b of the first portion 1620 can be spaced outward from the respective edges 1606 and 1608 with respect to the lateral direction A as described above, it should be appreciated that one or both of the outermost sides 1620a and 1620b can be aligned with, or at least not extend outward from, the respective first and second edges 1606 and 1608 as desired.

The first portion 1620 can extend out from at least one of the edges 1606 and 1608 along the lateral direction A. For instance, the first portion 1620 can extend out from both edges 1606 and 1608 of the contact beam 1616. Further portion 1620 can be coplanar with the broadsides 1610 and 1612. In alternative embodiments, the portion 1620 can extend out from only one of the first and second edges 1606 and 1608 along the lateral direction A. For example, one of the outermost sides 1620a and 1620b of the first portion 1620 can be spaced outward from a corresponding one of the first and second edges 1606 and 1608 with respect to the lateral direction A, and the other of the sides 1620a and 1620b of the first portion 1620 can extend up to a corresponding one of the first and second edges 1606 and 1608 of the contact beam 1616 along the lateral direction A.

The first portion 1620 can define a body 1620c and at least one shoulder, such as a first upper shoulder 1620d that extends from the body 1620c to the contact body 1607, and in particular to one of the first and second edges 1606 and 1608. The first portion 1620 can also define a second upper shoulder 1620d that extends from the body 1620c to the contact body 1607 and in particular to the other one of the first and second edges 1606 and 1608. It should be appreciated that one or both of the first and second upper shoulders 1620d can be omitted in some embodiments. Each upper shoulder 1620d can extend from the portion 1620 to the contact body 1607 along a direction having a directional component along the lateral direction A.

The intermediate portion 1624 can define opposed outermost sides 1624a and 1624b. The outermost sides 1624a and 1624b can be spaced from each other along the lateral direction A. In one example, the intermediate portion defines a width W₃ from one of the outermost sides 1624a and 1624b to the other of the outermost sides 1624 and 1624b. The width W₃ of the intermediate portion 1624 can be less than the corresponding width of one or both of the portions 1620 and 1626. For instance, the width W₃ of the intermediate portion 1624 can be less than the width of the broadsides 1610 and 1612 from one of the edges 1606 and 1608 to the other of the edges 1606 and 1608. Alternatively, the width W₃ of the intermediate portion 1624 can be greater than the width of the broadsides 1610 and 1612. Alternatively still, the outermost sides 1624a and 1624b can be defined by the first and second edges 1606 and 1608, respectively. Thus, the width W₃ of the intermediate portion 1624 can be substantially equal to the width of the broadsides 1610 and 1612.

The intermediate portion 1624 can extend between the first portion 1620 and the mounting end 1602 along the longitudinal direction L. For instance, the intermediate portion 1624 can extend from the first portion 1620 toward the mounting end 1602. The intermediate portion 1624 can define a maximum length L_max,5 along the longitudinal direction L. The intermediate portion 1624 can have a substantially rectangular shape in a plane defined by the longitudinal and lateral directions as shown, or can have any other suitable shape in the plane such as a circle, square, or other polygon. Further, the first outermost side 1624a can be linear as it extends from the first portion 1620 towards the mounting end 1602. Similarly, the second outermost side 1624b can be linear as it extends from the first portion 1620 towards the mounting end 1602. Alternatively, one or both of the first and second outermost sides 1624a and 1624b can be curved between the first portion 1620 and the mounting end 1602. For example, one or both of the first and second outermost sides 1624a and 1624b can be concave between the first portion 1620 and the mounting end 1602.

As shown, the intermediate portion 1624 of the electrical contact 1152 can be elongate along the longitudinal direction L as it extends between the first portion 1620 and the mounting end 1602, such that the maximum length L_max,5 of the intermediate portion 1624 is greater than each of the width W₃ of the intermediate portion 1624 along the lateral direction and the thickness of the intermediate portion 1624 along the transverse direction T. Further, the intermediate portion 1624 of the electrical contact 1152 can be shortened in comparison to the intermediate portions 1424 and 1524 of the electrical contacts 1144 and 1146, such that the maximum length L_max,5 of the intermediate portion 1624 is less than or equal to one or more of the width W₃ of the intermediate portion 1624 and the thickness of the intermediate portion 1624, or can be eliminated altogether.

The first portion 1620 can define at least one lower shoulder, such as a first lower shoulder 1620e that extends from the body 1620c of the first portion 1620 to the intermediate portion 1624. For instance, the first lower shoulder 1620e can extend from one of the outermost sides 1620a and 1620b to a corresponding one of the outermost sides 1624a and 1624b. The first portion 1620 can also define a second lower shoulder 1620e that extends from the body 1620c to the intermediate portion 1624. For instance, the second lower shoulder 1620e can extend the other of the outermost sides 1620a and 1620b to the corresponding other of the outermost sides 1624a and 1624b. It should be appreciated that one or both of the first and second lower shoulders 1620e can be omitted in some embodiments. Each lower shoulder 1620e can extend from the portion 1620 to the intermediate portion 1624 along a direction having a directional component along the lateral direction A. Further, each lower shoulder 1620e can face away from a corresponding upper shoulder 1620d.

The second portion 1626 can define opposed outermost sides 1626a and 1626b. The outermost sides 1626a and 1626b can be spaced from each other along the lateral direction A. The outermost sides 1626a and 1626b can be outwardly spaced from the respective first and second sides 1624a and 1624b of the intermediate portion 1624 along the lateral direction A. The outermost sides 1626a and 1626b can also be outwardly spaced from the respective first and second edges 1606 and 1608 along the lateral direction A. The second portion 1626 can have a width W₄ along the lateral direction A from the first outermost side 1626a to the second outermost side 1626b, the width W₄ being greater than the width W₂ of the broadsides 1610 and 1612 from the first edge 1606 to the second edge 1608. The second portion 1626 can extend between the contact beam 1616 and the mounting end 1602, such as from the mounting end 1602 towards the contact beam 1616. The second portion 1626 can have a substantially rectangular shape in a plane defined by the longitudinal and lateral directions as shown, or can have any other suitable shape in the plane such as a circle, square, or other polygon. Further, the second portion 1626 has a maximum length L_max,6. While the outermost sides 1626a and 1626b of the second portion 1626 can be spaced outwardly from the respective first and second sides 1624a and 1624b with respect to the lateral direction A as described above, it should be appreciated that one or both of the outermost sides 1626a and 1626b can be continuous with the respective first and second sides 1624a and 1624b as desired.

The second portion 1626 can extend outward from at least one of the sides 1624a and 1624b of the intermediate portion 1624 along the lateral direction A. For instance, the second portion 1626 can extend outward from both of the sides 1624a and 1624b of the intermediate portion 1624. Further, the second portion 1626 can be coplanar with the broadsides 1610 and 1612. In alternative embodiments, the second portion 1626 can extend out from only one of the first and second sides 1624a and 1624b along the lateral direction A. For example, one of the outermost sides 1626a and 1626b of the second portion 1626 can be spaced outward from a corresponding one of the first and second sides 1624a and 1624b with respect to the lateral direction A, and the other of the sides 1626a and 1626b of the second portion 1626 can be aligned with, or at least not extend outward from, a corresponding one of the first and second sides 1624a and 1624b of the intermediate portion.

The second portion 1626 can define a body 1626c and at least one shoulder, such as a first upper shoulder 1626d that extends from the body 1626c to the intermediate portion 1624, and in particular to one of the first and second sides 1624a and 1624b of the intermediate portion 1624. The second portion 1626 can also define a second upper shoulder 1626d that extends from the body 1626c to the intermediate portion 1624, and in particular to the other one of the first and second sides 1624a and 1624b of the intermediate portion 1624. It should be appreciated that one or both of the first and second upper shoulders 1626d can be omitted in some embodiments. Each upper shoulder 1620d can extend from the portion 1626 to the contact body intermediate portion 1624 along a direction having a directional component along the lateral direction A. Further, each upper shoulder 1626c can face a corresponding lower shoulder 1620c of the first portion 1620.

The second portion 1626 can define at least one lower shoulder, such as a first lower shoulder 1626e that extends from the body 1626c of the second portion 1626 to the mounting tail 1634. For instance, the first lower shoulder 1626e can extend from one of the outermost sides 1626a and 1626b to a corresponding side of the mounting tail 1634. The second portion 1626 can also define a second lower shoulder 1626e that extends from the body 1626c of the second portion 1626 to the mounting tail 1634. For instance, the second lower shoulder 1626e can extend from the other one of the outermost sides 1626a and 1626b to a corresponding side of the mounting tail 1634. It should be appreciated that one or both of the first and second lower shoulders 1626e can be omitted in some embodiments. Each lower shoulder 1626e can extend from the portion 1626 to the mounting tail 1634 along a direction having a directional component along the lateral direction A. Further, each lower shoulder 1626e can face away from a corresponding upper shoulder 1626d.

The contact beam 1616 can be constructed as a flexible beam having a bent, such as curved, shape that extends from the anchoring region 1614 to a free end 1618 of the electrical contact 1152. Bent structures as described herein refer to bent shapes that can be fabricated, for instance, by bending the end or by stamping a bent shape, or by any other suitable manufacturing process. The first broadside 1610 at the contact beam 1616 is configured to wipe against the second complementary electrical component 1300 as the component is mated with the contact beam 1616 along the longitudinal direction L. Further, the contact beam 1616 is configured to contact the second complementary electrical component 1300 so as to apply a force to a surface of the complementary electrical component 1300 along the transverse direction T.

The contact beam 1616 can include at least a first transverse bend region 1630 between the anchoring region 1614 and the mating end 1604. The first bend region 1630 can curve towards the first transverse direction that extends from the second broadside 1612 toward the first broadside 1610 as the contact beam 1616 extends away from the anchoring region 1614 along the longitudinal direction L. The contact beam 1616 can further include at least a second transverse bend region 1632 that is between the first bend region 1630 and the mating end 1604. The second bend region 1632 can curve towards the second transverse direction, opposite the first transverse direction, that extends from the first broadside 1610 toward the second broadside 1612 as the contact beam 1616 extends away from the first bend region 1630 along the longitudinal direction L. In alternative embodiments, the curvature of the contact beam 1616 can vary from that shown. For example, the contact beam 1616 can include as few as one bend region, or greater than two bend regions.

At the contact beam 1616, at least one of the first and second edges 1606 and 1608 can taper toward the other of the first and second edges 1606 and 1608 as the contact body extends along a direction from the anchoring region 1614 toward the mating portion 1617. For example, the first edge 1606 can taper towards the second edge 1608 as the first edge 1606 extends from the anchoring region 1614 to at least the second bend region 1632 or the free end 1618. Similarly, the second edge 1608 can taper toward the first edge 1606 as the second edge 1606 extends from the anchoring region 1614 to at least the second bend region 1632 or the free end 1618. Alternatively, one or both of the first and second edges can extend along the longitudinal direction L as the contact body 1607 extends from the anchoring region 1614 to at least the second bend region 1632 or the free end 1618. For instance, the first and second edges 1606 and 1608 can be parallel with each other as the contact body 1607 extends from the anchoring region 1614 to at least the second bend region 1632 or the free end 1618. As another example, the second edge 1608 can taper towards the first edge 1606 as the second edge 1608 extends from the anchoring region 1614 to at least the second bend region 1632 or the free end 1618, while the first edge 1606 can extend along the longitudinal direction L as the first edge 1606 extends from the anchoring region 1614 to at least the second bend region 1632 or the free end 1618. As yet another example, the first and second edges 1606 and 1608 can taper towards each other as they extend from the anchoring region 1614 to at least the second bend region 1632 or the free end 1618. Alternatively, the first and second edges 1606 and 1608 can be parallel to one another along at least a portion up to an entirety of the length of the contact beam 1616.

The anchoring region 1614 can define a central axis CA that extends in the longitudinal direction between the first and second broadsides 1610 and 1612. The second bend region 1632 can extend at least partially on a first side of the central axis CA with respect to the transverse direction T, the first side being spaced from the central axis CA along a direction that is opposite the second broadside 1612. Further, the free end 1618 can be positioned on a second side of the central axis CA with respect to the transverse direction T, the second side being spaced from the central axis CA along a direction that is opposite the first broadside 1610.

The mounting end 1602 can include a mounting tail 1634 that extends away from the anchoring region 1614. For example, the mounting tail 1634 can define a surface-mount tail as shown that is bent, or otherwise curved, outward from the anchoring region 1614 along the transverse direction T, such as along a direction that extends from the first broadside 1610 towards the second broadside 1612. Thus, the mounting tail 1634 can be disposed on the same side of the central axis CA as the free end 1618 with respect to the transverse direction T as shown in FIG. 28. Alternatively, the mounting tail 1634 can extend on the opposite side of the central axis CA as the free end 1618. The mounting tail 1634 defines a terminal end 1636 of the electrical contact 1152. The terminal end 1636 can be configured as a mounting surface that mounts onto, such as abuts, an electrical contact of the first complementary electrical component 1200. The mounting surface can substantially face the longitudinal direction L, such as in a direction away from the free end 1618 of the electrical contact. Thus, the mounting surface can be configured to mount onto a complementary electrical component that lies in a plane that is substantially perpendicular to the longitudinal direction L. In alternative embodiments, the mounting tail 1634 can be configured as a differently-configured surface-mount tail, as a press-fit tail, as a fusible element such as a solder ball, or combinations thereof.

The electrical contact 1152 defines maximum length L_max,1 along the longitudinal direction L from the free end 1618 to the terminal end 1636. The electrical contact 1152 further defines a maximum width W_max,1 along the lateral direction A. The maximum width W_max,1 can be equal to at least one of the width W₁ of the first portion 1620 and the width W₄ of the second portion 1626, such as a larger of the widths W₁ and W₄. Alternatively, the maximum width W_max,1 can be equal to both the width W₁ of the first portion 1620 and the width W₄ of the second portion 1626 when the widths W₁ and W₄ are equal. The contact body 1607 yet further defines a maximum thickness T_max along the transverse direction T from one of the opposed broadsides 1610 and 1612 to the other. The maximum length L_max,1 of the electrical contact 1152 is greater than both the maximum width W_max,1 and the maximum thickness T_max. Further, the maximum width W_max,1 of the electrical contact 1152 can be greater than the maximum thickness T_max. Thus, the electrical contact 1152 can be said to be elongate along the longitudinal direction L.

Turning now to FIGS. 30 and 31, embodiments of the present disclosure can include a kit having two or more of (i) at least a first electrical contact 1144 of FIGS. 21 to 23, (ii) at least a second electrical contact 1146 of FIGS. 24 to 26, (iii) at least a third electrical contact 1152 of FIGS. 27 to 29, and at least a fourth contact 1152 of FIGS. 27 to 29. For example, a kit can include at least one pair 1142 of the at least first electrical contact 1144 and the at least second electrical contact 1146. As shown, each pair 1142 of the first and second electrical contacts 1144 and 1146 can be arranged edge-to-edge such that the second edge 1408 of the first electrical contact 1144 faces the first edge 1506 of the second electrical contact 1146. At least a portion of the second edge 1408 of the first electrical contact 1144 can be substantially parallel to at least a portion of the first edge 1506 of the second electrical contact 1146. Further, at least one, up to all, of the sides 1420b, 1424b, and 1426b of the first electrical contact 1144 can be parallel to at least one, up to all, of the sides 1520a, 1524a, and 1526a of the second electrical contact 1146.

The inner edges 1408 and 1506 of the contact beams 1416 and 1516 of the first and second electrical contacts 1144 and 1146 define the inner-most points of the first and second electrical contacts 1144 and 1146 along the lateral direction A. Therefore, the contact beams 1416 and 1516 of the first and second electrical contacts 1144 and 1146 can be closer to one another than comparable electrical connectors where the anchoring regions, not the contact beams, define the inner-most points. Without being bound by theory, it is believed that the closer spacing can result in the contact beams 1416 and 1516 of the first and second electrical contacts 1144 and 1146 being more tightly coupled together than comparable contacts having inner edges that are not linear. Further, it is believed that the tighter coupling can increase the power flow of the signals in between the first and second electrical contacts 1144 and 1146 along the longitudinal direction L, can improve impedance control, and can reduce crosstalk.

The first and second electrical contacts 1144 and 1146 can be arranged such that their respective mounting ends 1402 and 1502 are aligned along the lateral direction A. In this arrangement, at least a portion of the anchoring region 1414 of the first electrical contact 1144 can be substantially aligned with at least a portion of the anchoring region 1514 of the second electrical contact 1146 along the lateral direction A. The anchoring regions 1414 and 1514 can each define an upper-most point and a lower-most point of the respective anchoring regions 1414 and 1514 along the longitudinal direction L, the upper-most points being closest to the respective mating ends 1404 and 1504 and the lower-most points being closest to the respective mounting ends 1402 and 1502.

For example, the lower-most point of the anchoring region 1614 can be substantially aligned with the lower-most point of one or both of the anchoring regions 1414 and 1514. As shown, the upper-most point of the anchoring region 1614 can be aligned with one or both of the first portions 1420 and 1426 of the first and second contacts 1144 and 1146 along the lateral direction A, between the respective upper-most and lower-most points of the first portions 1420 and 1426.

In addition, or alternatively, a center of the second portion 1626 of the third electrical contact 1152 can be substantially aligned with a center of one or both of the second portions 1426 and 1526 along the lateral direction A. Alternatively still, a portion of the second portion 1626 can be aligned with a portion of one or both of the second portions 1426 and 1526 along the lateral direction A, without one or both of the upper-most point and lower-most point of the second portion 1626 being aligned with a corresponding one of the upper-most point and lower-most point of the second portions 1426 and 1526.

At least a portion of the intermediate portion 1624 of the third electrical contact 1152 can be substantially aligned with a portion of one or both of the anchoring regions 1414 and 1514 between the mounting ends 1402 and 1502 of the anchoring regions 1414 and 1514 and their respective first portions 1420 and 1520 along the lateral direction A. The intermediate portion 1624 can define an upper-most point and a lower-most point of the respective intermediate portion 1624 along the longitudinal direction L, the upper-most point being closest to the respective mating end 1604 and the lower-most point being closest to the mounting ends 1602.

Alternatively, the upper-most point of the intermediate portion 1624 can be substantially aligned with the lower-most point of the first portion 1420, the lower-most point of the first portion 1520, or both, along the lateral direction A.

The first portion 1620 can be staggered with respect to the first portions 1420 and 1520 of the first and second contacts 1144 and 1146 along the lateral direction A. For example, the first portion 1620 can be substantially aligned between the second portion 1426 of the first electrical contact 1144 and the upper-most point of the anchoring region 1414, between the second portion 1526 of the second electrical contact 1146 and the upper-most point of the anchoring region 1514, or both, along the lateral direction A. The first portion 1620 can define an upper-most point and a lower-most point of the respective first portion 1620 along the longitudinal direction L, the upper-most point being closest to the respective mating end 1604 and the lower-most point being closest to the mounting end 1602. The first portion 1620 can define its maximum length L_max,4 from its upper-most point to its lower-most point. In at least some embodiments, the upper-most point of the first portion 1620 can define the upper-most point of the anchoring region 1614.

The lower-most point of the first portion 1620 can be substantially aligned between the second portion 1426 and the upper-most point of the anchoring region 1414, between the second portion 1526 and the upper-most point of the anchoring region 1514, or both. For example, the lower-most point of the first portion 1620 can be substantially aligned between the second portion 1426 and the lower-most point of the first portion 1420, between the second portion 1526 and the upper-most point of the first portion 1520, or both. Alternatively, the lower-most point of the first portion 1620 can be substantially aligned with the lower-most point of one or both of the first portions 1420 and 1520.

The upper-most point of the first portion 1620 can be substantially aligned between the second portion 1426 and the upper-most point of the first portion 1420, between the second portion 1526 and the upper-most point of the first portion 1520, or both, along the lateral direction A. For example, the upper-most point of the first portion 1620 can be substantially aligned between the upper-most and lower-most points of the first portion 1420, between upper-most and lower-most points of the first portion 1520, or both, along the lateral direction A. In at least some embodiments, the first portion 1620 can have a center that is aligned between the second portion 1426 and the lower-most point of the first portion 1420, between the second portion 1526 and the upper-most point of the first portion 1520, or both, along the lateral direction. Alternatively, the upper-most point of the first portion 1620 can be substantially aligned with the upper-most point of one or both of the first portions 1420 and 1520. Thus, the center of the first portion 1620 can be substantially aligned with the center of one or both of the first portions 1420 and 1520.

Each of the first and second electrical contacts 1144 and 1146 can have a maximum length L_max,1 along the longitudinal direction L from their mounting ends 1402 and 1502 to their respective mating ends 1404 and 1504 that is greater than a maximum length L_max,1 of the third electrical contact 1152 along the longitudinal direction L from its mounting end 1602 to its mating end 1604. However, in alternative embodiments, the maximum lengths L_max,1 of the first, second, and third electrical contacts can be equal. Further, each of the anchoring regions 1414 and 1514 of the first and second electrical contacts 1144 and 1146 can have a maximum length L_max,2 that is greater than a maximum length L_max,2 of the anchoring region 1614 of the third electrical contact 1152. However, in alternative embodiments, the maximum lengths L_max,2 of the anchoring regions of the first, second, and third electrical contacts can be equal. Yet further, each of the intermediate portions 1426 and 1526 of the first and second electrical contacts 1144 and 1146 can have a maximum length L_max,5 that is greater than a maximum length L_max,5 of the intermediate portion 1626 of the third electrical contact 1152. However, in alternative embodiments, the maximum lengths L_max,5 of the intermediate portions of the first, second, and third electrical contacts can be equal. Yet still further, each of the contact beams 1416 and 1516 of the first and second electrical contacts 1144 and 1146 can have a maximum length L_max,3 that is substantially equal to a maximum length L_max,3 of the contact beam 1616 of the third electrical contact 1616. However, in alternative embodiments, the maximum lengths L_max,3 of the contact beams of the first, second, and third contacts can vary. For example, the length of each stub 1419 and 1519 can be greater than the length of the stub 1619. The maximum lengths L_max,4 of the first portions of the first, second, and third contacts can be equal as shown or can vary from one another. Similarly, the maximum lengths L_max,6 of the second portions of the first, second, and third contacts can be equal as shown or can vary from one another.

The second portion of each one of the first, second and third contacts 1144, 1146, and 1152 can be considered the lower-most enlarged portion of the contact with respect to its mounting end. Thus, the anchoring region 1414 of the first contact 1144 has a lower-most enlarged portion 1426 that is closest to the mounting end 1402, the anchoring region 1514 of the second contact 1146 has a lower-most enlarged portion 1526 that is closest to the mounting end 1502, and the anchoring region 1614 of the third contact 1152 has a lower-most enlarged portion 1626 that is closest to the mounting end 1602. The lower-most enlarged portions 1426 and 1626 of the first and third contacts 1144 and 1152 can be aligned with one another along the lateral direction A. For example, the lower-most enlarged portions 1426 and 1626 of the first and third contacts 1144 and 1152 can be fully aligned with one another along the lateral direction A. All other enlarged portions of the anchoring region of the third contact 1152 can have at least a portion that is out of alignment with all other enlarged portions of the anchoring regions of the first and second contacts 1144 and 1146. Similarly, all other enlarged portions of the anchoring regions of the second and third contacts 1144 and 1146 can have at least a portion that is out of alignment with all other enlarged portions of the anchoring region of the third contacts 1152.

Further, the lower-most enlarged portions 1526 and 1626 of the second and third contacts 1146 and 1152 can be aligned with one another along the lateral direction A. For example, the lower-most enlarged portions 1526 and 1626 of the second and third contacts 1146 and 1152 can be fully aligned with one another along the lateral direction A. All other enlarged portions of the anchoring region of the third contact 1152 can have at least a portion that is out of alignment with all other enlarged portions of the anchoring region of the second contact 1146.

Now the dimensions of the third electrical contact 1152 will be compared with the dimensions of the first and second electrical contacts 1144 and 1146. The first and second electrical contacts each have a maximum length L_max,1 from their respective mounting tails 1434 and 1534 to their respective free ends 1418 and 1518 that is greater than a maximum length L_max,1 of the third electrical contact 1152 from its mounting tail 1534 to its free end 1618. The difference in the maximum lengths L_max,1 can be attributed at least in part to a difference in the lengths L_max,2 of the anchoring regions of the first, second, and third electrical contacts 1144, 1146, and 1152. The maximum length L_max,2 of each of the anchoring regions 1414 and 1514 of the first and second electrical contacts 1144 and 1146 can be greater than the maximum length L_max,2 of the anchoring region 1614 of the third electrical contact 1152. Further, the maximum length L_max,5 of each of the intermediate portions 1426 and 1526 of the first and second electrical contacts 1144 and 1146 can be greater than the maximum length L_max,5 of the intermediate portion 1626 of the third electrical contact 1152. Yet further, the maximum lengths L_max,4 of the portions 1420, 1520, and 1620 of the first, second, and third electrical contacts 1144, 1146, and 1152 can be equal, the maximum lengths L_max,6 of the second portions 1426, 1526, and 1626 of the first, second, and third electrical contacts 1144, 1146, and 1152 can be equal, the maximum lengths of the mounting tails 1434, 1534, and 1634 of the first, second, and third electrical contacts 1144, 1146, and 1152 can be equal, and the maximum lengths L_max,3 of the contact beams 1416, 1516, and 1616 of the first, second, and third electrical contacts 1144, 1146, and 1152 can be equal. It is noted that, in alternative embodiments, one or more of these lengths may vary from the first and second electrical contacts 1144 and 1146 to the third electrical contact 1152.

The maximum widths W_max of the first, second, and third electrical contacts 1144, 1146, and 1152 can be equal or can vary from one another. Similarly, the maximum thicknesses T_max of the first, second, and third electrical contacts 1144, 1146, and 1152 can be equal or can vary from one another. Moreover, in alternative embodiments, one or more of the maximum lengths L_max,4, the maximum lengths L_max,6, and the maximum lengths L_max,3 of the first, second, and third electrical contacts 1144, 1146, and 1152 can be vary from one another.

In at least some embodiments, the dimensions of the electrical contact 1144 of FIGS. 21 to 23 can be as follows: the length L_max,1 can be between approximately 7 mm and approximately 16 mm, the length L_max,2 can be between approximately 3 mm and approximately 8 mm, the length L_max,3 can be between approximately 4 mm and approximately 8 mm, the length L_max,4 can be between approximately 0.5 mm and approximately 2 mm, the length L_max,5 can be between approximately 1.0 mm and 6 mm, the length L_max,6 can be between approximately 0.5 mm and approximately 2 mm, the width W_max,1 can be between approximately 0.3 mm and approximately 0.9 mm, the width W₁ can be between approximately 0.3 mm and approximately 0.9 mm, the width W₂ can be between approximately 0.2 mm and approximately 0.5 mm, the width W₃ can be between approximately 0.2 mm and approximately 0.5 mm, and the thickness T_max can be between approximately 0.125 mm and approximately 0.225 mm.

In at least some embodiments, the dimensions of the electrical contact 1146 of FIGS. 24 to 26 can be as follows: the length L_max,1 can be between approximately 6 mm and approximately 12 mm, the length L_max,2 can be between approximately 2 mm and approximately 6 mm, the length L_max,3 can be between approximately 4 mm and approximately 8 mm, the length L_max,4 can be between approximately 0.5 mm and approximately 2 mm, the length L_max,5 can be between approximately 1.0 mm and 6 mm, the length L_max,6 can be between approximately 0.5 mm and approximately 2 mm, the width W_max,1 can be between approximately 0.3 mm and approximately 0.9 mm, the width W₁ can be between approximately 0.3 mm and approximately 0.9 mm, the width W₂ can be between approximately 0.2 mm and approximately 0.5 mm, the width W₃ can be between approximately 0.2 mm and approximately 0.5 mm, and the thickness T_max can be between approximately 0.125 mm and approximately 0.225 mm.

Referring now to FIGS. 32 and 33, each insert mold assembly 1122 can include an insert mold body 1118, a first set 1140 of electrical contacts supported by the insert mold body 1118, and a second set 1150 of electrical contacts supported by the insert mold body 1118. The insert mold body 1118 can include first and second lateral ends 1702 and 1704, and first and second sides 1706 and 708. The first and second ends 1702 and 1704 can be spaced opposite from one another along the lateral direction A (or row direction R). Thus, the first and second lateral ends 1702 and 1704 can face away from one another. The first and second sides 1706 and 1708 can be spaced opposite from one another along the transverse direction T (or column direction C). Thus, the first and second sides 1706 and 1708 can face away from one another. It should therefore be appreciated that each of the first and second lateral ends 1702 and 1704 can be connected between the first and second sides 1706 and 1708. Similarly, each of the first and second sides 1706 and 1708 can be connected between the first and second lateral ends 1702 and 704.

The insert mold body 1118 can also include a mounting end 1710 and a mating end 1712 that are spaced opposite from one another along the longitudinal direction L. The insert mold body 1118 can be insert molded around the electrical contacts 1120 such that the mounting ends 1402, 1502, and 1602 of the electrical contacts 1144, 1146, and 1152 extend from the mounting end 1710 of the insert mold body 1118 and the mating ends 1404, 1504, and 1604 of the electrical contacts 1144, 1146, and 1152 extend from the mating end 1712 of the insert mold body 1118.

The mounting end 1710 can be terminate between the upper-most point and lower-most point of each of the second portions 1426, 1526, and 1626 of the electrical contacts 1144, 1146, and 1152. Further, the mating end 1712 can terminate between the upper-most point and lower-most point of each of the first portions 1420, 1520, and 1620 of the electrical contacts 1144, 1146, and 1152. As described above, the first portion 1620 can be staggered with respect to the first portions 1420 and 1520 of the first and second contacts 1144 and 1146 along the lateral direction A. To accommodate this staggering, the insert mold body 1118 can define a recess 1714 for each of the contacts 1152, wherein the mating end 1712 defines the bottom of the recesses 1714. Thus, the mating end 1712 can define a saw-tooth pattern, where the bottom-most points of the saw-tooth pattern align with the first portions 1620 of the third electrical contacts 1152.

The insert mold body 1118 supports the first set 1140 of electrical contacts and the second set 1150 of electrical contacts in a row. The first set 1140 of electrical contacts in each row can include at least one pair 1142 of adjacent electrical contacts 1144 and 1146 that are configured as discussed above in relation to FIGS. 21 to 26. For instance, the first set 1140 can include a plurality of pairs 1142 of adjacent electrical contacts 1144 and 1146. The second set 1150 can include at least one, such as a plurality, of the electrical contacts 1152, each configured as discussed above in relation to FIGS. 27 to 29. The contacts of the first and second sets 1140 and 1150 can be arranged edge-to-edge along the row direction R as discussed above in relation to FIGS. 30 and 31. Four pairs 1142 of the electrical contact 1144 and 1146 and five instances of the electrical contact 1152 are shown. However, embodiments of the present disclosure can include as few as one pair 1142 and one contact 1152, or more than four pairs 1142 and more than five instances of the electrical contact 1152.

The electrical contacts of the pairs 1142 can be arranged such that the individual contacts of each pairs 1142 are adjacent one another and spaced from one another along a row direction R, which in this embodiment is aligned with the lateral direction A and is perpendicular to both the longitudinal direction L and transverse direction T. The individual contacts of each of the pairs 1142 can be immediately adjacent one another without any other electrical contact therebetween. The pairs 1142 of the electrical contacts can be arranged such that at least one of the electrical contacts 1152 of the second set 1150 is disposed between adjacent pairs 1142 of the electrical contacts along the row direction R. The adjacent pairs 1142 of the electrical contacts can be immediately adjacent one another without any other pair 1142 of the electrical contacts therebetween. Thus, the electrical contacts can be arranged along the row direction in the following pattern: first electrical contact 1144-second electrical contact 1146-third electrical contact 1152-first electrical contact 1144-second electrical contact 1146-third electrical contact 1152, which can be repeated.

In some embodiments, each first and second electrical contact 1144 and 1146 can define a signal contact, and each third electrical contact 1152 can define ground contact. Further, each pair 1142 of the signal contacts can define a differential signal pair. Thus, the electrical contacts in the arrangement of FIGS. 30 to 33 can define the following pattern along the row direction R from left to right: ground-signal-signal-ground-signal-signal, which can be repeated. As such, the signal contacts 1144 and 1146 can each have a maximum length L_max,1 along the longitudinal direction L that is greater than the maximum length L_max,1 of each of the ground contacts 1152 along the longitudinal direction L.

Without being bound by theory, it is believed that anchoring regions of electrical contacts having larger surface areas can suffer from greater drops in impedance than anchoring regions with smaller surfaces areas. However, retention of electrical contacts within connector housings can be weaker for electrical contacts having smaller anchoring regions than for electrical contacts having larger anchoring regions. Contacts 1144, 1146, and 1152 balance these competing concerns (i.e., impedance vs. retention) by (i) reducing the surface area of their respective anchoring regions at the intermediate portions to reduce the impedance drop at the anchoring regions and (ii) maintaining enlarged regions to support contact retention. As a result, each of contacts 1144, 1146, and 1152 can have an improved impedance profile over a comparable contact having an anchoring region with larger surface area, namely, the impedance of the contacts 1144, 1146, and 1152 at their respective anchoring regions do not drop as significantly as the impedance of comparable contacts at their anchoring regions.

Further, the closer spacing of the contact beams 1416 and 1516 of the signal contacts 1144 and 1146 can result in the signal contacts 1144 and 1146 being more tightly coupled together than comparable contacts having inner edges that are not linear. It is believed that the tighter coupling can increase the power flow of the signals in between the first and second electrical contacts 1144 and 1146 along the longitudinal direction L, can improve impedance control, and can reduce crosstalk. Moreover, spacing the contact beams 1416 and 1516 of the signal contacts 1144 and 1146 closer together, while maintaining the same distance from one ground contact 1152 to the next, increases the spacing between (i) the contact beams 1416 and 1516 of the signal contacts 1144 and 1146 and (ii) the contact beams 1616 of the ground contacts 1152. It is believed that increasing this spacing reduces coupling between (i) the signal contacts 1144 and 1146 and (ii) the ground contacts 1152.

As shown in FIGS. 30 to 33, a portion of the contact beams 1416 and 1516 of the first and second electrical contacts 1144 and 1146 in each pair 1142 can flare away from one another as contact beams 1416 and 1516 extend toward their respective free ends 1418 and 1518. Further, the inner stubs 1419 and 1519 of the first and second electrical contacts 1144 and 1146 in each pair 1142 can be spaced further from one another than the inner sides of the anchoring regions 1414 and 1514. Spacing the stubs 1419 and 1519 away from one another can reduce capacitive coupling between the first and second contacts 1144 and 1146, resulting in less interference between the signals conducted over the first and second contacts 1144 and 1146 than if the stubs 1419 and 1519 were spaced closer together to one another. Moreover, arranging the shorter contacts 1152 adjacent the pairs 1142 of contacts can result in lower capacitive coupling between (i) the flared stubs 1419 and 1519 and (ii) the adjacent contacts than would occur if the contacts 1152 were longer.

Without being bound by theory, it is believed that designating the shortened contacts 1152 in the rows of FIGS. 30 to 33 as ground contacts can shift common mode resonance of the contacts 1152 out in frequency to improve crosstalk. Further, it is believed that interspersing the shortened ground contacts 1152 with the elongated signal contacts 1144 and 1146 as shown in FIGS. 30 to 33 can place the beam profiles of the shortened ground contacts 1152 out of plane with those of the elongated signal contacts 1144 and 1146 so to allow signal pair cancellation on ground beam, which can result in reduced cross coupling or crosstalk. Moreover, it is believed that interspersing the shortened ground contacts 1152 with the elongated signal contacts 1144 and 1146 can reduce capacitance of the tips 1419 and 1519 of the elongated signal contacts 1144 and 1146. This in turn allows the tips 1419 and 1519 of the elongated signal contacts 1144 and 1146 to be lengthened for a mechanical advantage where longer tips can be more robust to avoid stub damage when the electrical connector 1100 is mated with the second complementary component 1300. Each of the aforementioned characteristics enables the connector 1100 to operate at faster speeds than comparable prior art connectors, such as speeds up to or exceeding 140 Gigabytes/second.

In alternative embodiments, the contacts 1144, 1146, and 1150 can define an open pin field. For instance, each of the contacts 1144, 1146, and 1152 can define either a signal contact or a ground contact. Thus, the contacts can define grounds and signals in any desired pattern along the row direction R. For instance, the electrical contacts in the arrangement of FIGS. 30 to 33 can define the following pattern along the row direction R from left to right: ground-signal-ground-signal-ground-signal, which can be repeated.

In further alternative embodiments, the electrical contacts 1144, 1146, and 1152 can be arranged along the row direction in a different pattern, such as (without limitation): electrical contact 1144-electrical contact 1146-electrical contact 1152-electrical contact 1152-electrical contact 1144-electrical contact 1146-electrical contact 1152-electrical contact 1152, which can repeat.

Referring back to the connector 1100 in FIGS. 17 to 20, the connector housing 1102 has a mounting end 1104 and a mating end 1106 that are spaced from one another. The contacts 1144, 1146, and 1152 are supported by the housing 1102 such that their respective mounting end 1402, 1502, and 1602 are disposed at the mounting end 1104 of the housing 1102 and their respective mating ends 1404, 1504, and 1604 are disposed at the mating end 1106 of the housing. Further, first and second insert mold assemblies 1122a and 1122b can be bottom loaded into the connector housing 1102 through the mounting end 1104.

The electrical connector 1100 is a vertical electrical connector, wherein the mating end 1106 is configured to mate with the second complementary electrical component 1300 along a mating direction M_A that is aligned with the longitudinal direction L, and the mounting end 1104 is configured to mount to the first complementary electrical component 1200 along a mounting direction M_O that is also aligned with the longitudinal direction L. Thus, in FIGS. 17 to 20, the mating direction M_A and the mounting direction M_O are both aligned with (i.e., parallel to) the longitudinal direction L.

In alternative embodiments, the electrical connector can be a right-angle electrical connector, where the mating end 1106 is configured to mate with the second complementary electrical component 1300 along a mating direction M_A, and the mounting end 1104 is configured to mount to the first complementary electrical component 1200 along a mounting direction M_O, perpendicular to the mating direction M_A. In such embodiments, the mounting direction M_O can be aligned with the longitudinal direction L, and the mating direction M_A can be perpendicular to the longitudinal direction L, such as the transverse direction T.

The connector housing 1102 has first and second sidewalls 1108 and 1110 that extend from the mating end 1106 to the mounting end 1104. The first and second sidewalls 1108 and 1110 can be spaced from one another along the column direction C so as to define an insertion slot 1112 therebetween that is sized and configured to receive the second complementary electrical component 1300. The insertion slot 1112 defines a plane that extends along the mating direction M_A and the row direction R between the first and second rows R₁ and R₂. The connector housing 1102 can also include first and second endwalls 1114 and 1116 that are spaced from one another along the row direction R. The first and second endwalls 1114 and 1116 can extend from the mating end 1106 to the mounting end 1104 and from the first sidewall 1108 to the second sidewall 1110.

The first sidewall 1108 includes a first internal surface 1108a, and a first external surface 1108b spaced opposite from the first internal surface 1108a along the column direction C. Similarly, the second sidewall 1110 includes a second internal surface 1110a, and a second external surface 1110b spaced opposite from the second internal surface 1110a along the column direction C. The first and second internal surfaces 1108a and 1110a can face one another along the column direction C, and the first and second external surfaces 1108b and 1110b can face away from one another along the column direction C. Moreover, the first internal surface 1108a is spaced between the first external surface 1108b and the second sidewall 1110, while the second internal surface 1110a is spaced between the second external surface 1110b and the first sidewall 1108.

The first sidewall 1108 can include a first plurality of ribs 1108c that extend from the first internal surface 1108a towards the second sidewall 110. The ribs 1108c of the first plurality of ribs can be spaced from one another along the row direction R by a width that is greater than the width W₂ of the contact beams 1414, 1514, and 1614 of the electrical contacts 1144, 1146, and 1152. Each rib 1108c can be spaced between a different pair of immediately adjacent electrical contacts such that the edges of the immediately adjacent electrical contacts that face one another also face the rib 1108c.

Similarly, the second sidewall 1110 can include a second plurality of ribs 1110c that extend from the second internal surface 1110a towards the first sidewall 1108. The ribs 1110c of the first plurality of ribs can be spaced from one another along the row direction R by a width that is greater than the width W of the contact beams 1414, 1514, and 1614 of the electrical contacts 1144, 1146, and 1152. Each rib 1110c can be spaced between a different pair of immediately adjacent electrical contacts such that the edges of the immediately adjacent electrical contacts that face one another also face the rib 1110c.

With reference to the system 1000 of FIGS. 17 to 20, the system 1000 can include the electrical connector 1100 and at least one, or both, of (i) a first complementary electrical component 1200 and (ii) a second complementary electrical component 1300. The first complementary electrical component 1200 can be implemented as a PCB. The first complementary electrical component 1200 has opposed upper and lower surfaces 1202 and 1204 that are spaced from one another along the mounting direction M_O, where the upper surface 1202 is configured to couple to the mounting ends 1402, 1502, and 1602 of the electrical contacts 1144, 1146, and 1152 of the electrical connector 1100. The first complementary electrical component 1200 also has opposed first and second ends 1206 and 1208 that are spaced from one another along the column direction C, and opposed first and second sides 1210 and 1212 that are spaced from one another along the row direction R. The lower surface 1204 can also be said to be spaced from the upper surface 1202 along the mounting direction M_O.

The upper and lower surfaces 1202 and 1204 each extend from the first end 1206 to the second end 1208 and from the first side 1210 to the second side 1212 so as to define a planar surface having a width along the column direction C from the first end 1206 to the second end 1208, and a length from the first side 1210 to the second side 1212 along the row direction R. Further, the first complementary electrical component 1200 defines a thickness from the upper surface 1202 to the lower surface 1204 along the mounting direction M_O. The length and width are greater than the thickness. Thus, the first complementary electrical component 1200 is planar along the row direction R and the column direction C.

The first complementary electrical component 1200 has a dielectric substrate 1214, a first set of first conductive contact pads 1216 carried by the substrate 1214 at the upper surface 1202, and a second set of second conductive contact pads 1218 carried by the substrate 1214 at the upper surface 1202. The first and second sets of conductive contact pads are arranged in first and second rows R₁ and R₂ at the upper surface 1202 and that are spaced from one another along the column direction C.

Each first contact pad 1216 can include a first end 1216a, and a second end 1216b spaced from the first end 1216a along the column direction C. Further, each first contact pad 1216 can include opposed sides 1216c that are spaced from one another along the row direction R, and that extend from the first end 1216a to the second end 1216b. Each first contact pad 1216 can have a rectangular shape such that each first contact pad 1216 is elongate from its respective first end 1216a to its respective second end 1216b, or can have any suitable alternative shape such as a circle, square, or other polygon. Similarly, each second contact pad 1218 can include a first end 1218a, a second end 1218b spaced from the first end 1218a along the column direction C, and opposed sides 1218c that are spaced from one another along the row direction R, and that extend from the first end 1218a to the second end 1218b. Each second contact pad 1218 can have a rectangular shape such that each second contact pad 1218 is elongate from its respective first end 1218a to its respective second end 1218b, or can have any suitable alternative shape such as a circle, square, or other polygon.

The first contact pads 1216 within each row R₁ and R₂ are arranged in pairs 1220 and are positioned so as to mate with the pairs 1142 of the electrical contacts supported by the electrical connector 1100 in the corresponding rows R₁ and R₂ of the electrical connector 1100. Thus, each pair 1220 of the first contact pads 1216 aligns with a different pair 1142 of the electrical contacts along the mounting direction M_O when the second complementary electrical component 1200 is mated with the electrical connector 1100. The second contact pads 1218 within each row R₁ and R₂ are positioned so as to mate with the electrical contacts 1152 supported by the electrical connector 1100 in the corresponding rows R₁ and R₂ of the electrical connector 1100. Thus, each second contact pad 1218 aligns with a different electrical contact 1152 along the mounting direction M_O when the first complementary electrical component 1200 is mated with the electrical connector 1100.

The first and second sets of contact pads 1216 and 1218 can be arranged in a side-by-side manner along each row R₁ and R₂. The individual first contact pads 1216 within each pair 1220 are spaced apart from one another along the row direction R without any other contact pads therebetween. The pairs 1220 of first contact pads 1216 can be arranged such that at least one of the second contact pads 1218 is disposed between adjacent pairs 1220 of the first electrical contacts 1216 along the row direction R. The adjacent pairs 1220 of the first electrical contacts 1216 can be immediately adjacent one another without any other pair 1220 of the first electrical contacts 1216 therebetween. Thus, the electrical contacts can be arranged along the row direction R in the following pattern: second contact pad 1218-first contact pad 1216-first contact pad 1216-second contact pad 1218-first contact pad 1216-first contact pad 1216, which can be repeated.

Each first contact pad 1216 can define a signal contact pad, and each second contact pad 1218 can define a ground contact pad. Further, each pair 1220 of the first contact pads 1216 can define a differential signal pair. Thus, the contact pads in the arrangement of FIGS. 17 to 20 can define the following pattern along the row direction R from left to right: ground-signal-signal-ground-signal-signal, which can be repeated. Alternatively, each first contact pad 1216 can either a signal contact pad or a ground contact pad, and each second contact pad 1218 can define either a signal contact pad or a ground contact pad. Thus, the contact pads can define grounds and signals in any desired pattern along the row direction R. For instance, the electrical contact pads can define the following pattern along the row direction R from left to right: ground-signal-ground-signal-ground-signal, which can be repeated.

With continuing reference to the system 1000 of FIGS. 17 to 20, the second complementary electrical component 1300 can define a PCB such as an edge card. The second complementary electrical component 1300 has opposed first and second side surfaces 1302 and 1304 that are spaced from one another along the column direction C such that the first side surface 1302 mates with the electrical contacts of the first row R₁ of the electrical connector 1100, and the second side surface 1304 mates with the electrical contacts of the second row R₂ of the electrical connector 1100. The second complementary electrical component 1300 also has opposed insertion and trailing ends 1306 and 1308 that are spaced from one another along the mating direction M_A, and opposed first and second edges 1310 and 1312 that are spaced from one another along the row direction R. The insertion end 1306 can also be said to be spaced from the trailing end 1308 along the mating direction M_A.

The first and second side surfaces 1302 and 1304 each extend from the insertion end 1306 to the trailing end 1308 and from the first edge 1310 to the second edge 1312 so as to define a planar surface having a height along the mating direction M_A from the insertion end 1306 to the trailing end 1308, and a width from the first edge 1310 to the second edge 1312 along the row direction R. Further, the second complementary electrical component 1300 defines a thickness from the first side surface 1302 to the second side surface 1304 along the column direction C. The height and width are greater than the thickness. Thus, the second complementary electrical component 1300 is planar along the row direction R and the mating direction M_A. The insertion end 1306 can also be tapered such that the thickness of the insertion end 1306 decreases in the mating direction M_A.

The second complementary electrical component 1300 has a dielectric substrate 1314, a first plurality of first conductive contact pads 1316 carried by the substrate 1314 at the first side surface 1302, and a second plurality of second conductive contact pads 1318 carried by the substrate 1314 at the first side surface 1302. Each first contact pad 1316 can include a trailing end 1316a, and a leading end 1316b spaced from the trailing end 1316a along the mating direction M_A. Further, each first contact pad 1316 can include opposed sides 1316c that are spaced from one another along the row direction R, and that extend from the trailing end 1316a to the leading end 1316b. Each first contact pad 1316 can have a substantially rectangular shape such that each first contact pad 1316 is elongate from its respective trailing end 1316a to its respective leading end 1316b, or can have any suitable alternative shape such as a circle, square, or other polygon.

Similarly, each second contact pad 1318 can include a trailing end 1318a, a leading end 1318b spaced from the trailing end 1318a along the mating direction M_A, and opposed sides 1318c that are spaced from one another along the row direction R, and that extend from the trailing end 1318a to the leading end 1318b. Each second contact pad 1318 can have a rectangular shape such that each second contact pad 1318 is elongate from its respective trailing end 1318a to its respective leading end 1318b, or can have any suitable alternative shape such as a circle, square, or other polygon.

The first contact pads 1316 are arranged in pairs 1320 and are positioned so as to mate with the pairs 1142 of the electrical contacts 1144 supported by the electrical connector 1100 in the first row R₁. Thus, each pair 1320 of the first contact pads 1316 aligns with a different pair 1142 of the electrical contacts along the column direction C when the second complementary electrical component 1300 is mated with the electrical connector 1100. The second contact pads 1318 are positioned so as to mate with the electrical contacts 1152 supported by the electrical connector 1100 in the first row R₁. Thus, each second contact pad 1318 aligns with a different second electrical contact 1152 along the column direction C when the second complementary electrical component 1300 is mated with the electrical connector 1100.

The second side surface 1304 can carry contact pads in a pattern that substantially mirrors that of the first side surface 1302. Thus, the second complementary electrical component 1300 can also have a first set of conductive contact pads 1316 carried by the substrate 1314 at the second side surface 1304, and a second set of conductive contact pads 1318 carried by the substrate 1314 at the second side surface 1304, where the first and second sets of contact pads 1316 and 1318 are arranged as discussed above in relation to the first side surface 1302.

The first and second pluralities of contact pads 1316 and 1318 can be arranged in a side-by-side manner along the row direction R. The individual first contact pads 1316 within each pair 1320 can be spaced apart from one another along the row direction R without any other contact pads therebetween. The pairs 1320 of first contact pads 1316 can be arranged such that at least one of the second contact pads 1318 is disposed between adjacent pairs 1320 of the first electrical contacts 1316 along the row direction R. The adjacent pairs 1320 of the first electrical contacts 1316 can be immediately adjacent one another without any other pair 1320 of the first electrical contacts 1316 therebetween. Thus, the electrical contacts can be arranged along the row direction R in the following pattern: second contact pad 1318-first contact pad 1316-first contact pad 1316-second contact pad 1318-first contact pad 1316-first contact pad 1316, which can be repeated.

Each first contact pad 1316 can define a signal contact pad, and each second contact pad 1318 can define a ground contact pad. Further, each pair 1320 of the first contact pads 1316 can define a differential signal pair. Thus, the contact pads in the arrangement of FIGS. 17 to 20 can define the following pattern along the row direction R from left to right: ground-signal-signal-ground-signal-signal, which can be repeated. Alternatively, each first contact pad 1316 can define either a signal contact pad or a ground contact pad, and each second contact pad 1318 can define either a signal contact pad or a ground contact pad. Thus, the contact pads can define grounds and signals in any desired pattern along the row direction R. For instance, the electrical contact pads can define the following pattern along the row direction R from left to right: ground-signal-ground-signal-ground-signal, which can be repeated.
