The subject matter described and/or illustrated herein relates generally to communication systems having connector assemblies.
Connectors are known for interconnecting various components, such as cables, circuit boards, and/or the like. Some known connectors are coaxial connectors including one or more coaxial contacts including a signal element and a ground element that is arranged coaxially with the signal element. Each coaxial contact may have a cable terminated thereto. The coaxial connectors may be used for a wide variety of applications, such as, but not limited to, radio frequency (RF) interconnections. As one example, a backplane communication system may include a large backplane circuit board that includes one or more windows. Each window is configured to receive a coaxial connector that is also mounted to the backplane circuit board using, for example, hardware. As such, the coaxial connectors are presented along one side of the circuit board for mating with corresponding coaxial connectors of a daughter card assembly or assemblies. Other known connectors, such as pin and socket connectors, have signal contacts and ground contacts arranged in a contact array. Such connectors may be terminated to a substrate, such as a circuit board, for mating with a mating connector. Other known connectors, such as fiber optic connectors, include fiber optic contacts. Such fiber optic connectors may be mounted to a substrate, such as a circuit board.
Known connectors are not without disadvantages. For example, it may be desirable to have connectors that have a greater density of contacts. Even with greater densities, however, it may be difficult to mate the opposing connectors. For example, the contacts of the connectors may be exposed and at risk of being damaged if the connectors are not sufficiently aligned during the mating operation.
Accordingly, there is a need for a connector having a greater density of contacts that also enables alignment of the contacts during the mating operation.
In one embodiment, a connector assembly is provided including a connector module having a connector body extending between a front side and a rear side. The connector body has edges between the front side and the rear side. The edges include a first side edge, a second side edge opposite the first side edge, a first end edge and a second end edge opposite the first end edge. The connector body has contact channels therethrough between the front side and the rear side. The contact channels hold contacts in corresponding contact channels. The contacts are presented along the front side for engaging corresponding mating contacts of a mating connector. The front side faces in a mating direction along a mating axis. The connector assembly includes a mounting frame having a passage extending between a mating side and a mounting side of the mounting frame that face in opposite directions. The mounting frame has a first side wall, a second side wall opposite the first side wall, and an end wall between the first side wall and the second side wall. The mounting frame has a window between the first side wall and the second side wall opposite the end wall. The window is open to and provides access to the passage. The passage receives the connector body of the connector module through the window in a direction generally perpendicular to the mating axis. The mounting side faces in a mounting direction and is configured to interface with a support wall. The mounting frame includes a connector module support structure for supporting the connector module in the passage of the mounting frame. The connector module support structure defines a confined space oversized relative to the connector body of the connector module to allow a limited amount of floating movement in the confined space in a lateral direction that is perpendicular to the mating direction.
In another embodiment, a connector assembly is provided. The connector assembly is configured to be mounted to a support wall at an opening in the support wall defined by support wall edges extending between a first surface and a second surface of the support wall. The connector assembly includes a connector module having a connector body extending between a front side and a rear side. The connector body has edges between the front side and the rear side. The edges include a first side edge, a second side edge opposite the first side edge, a first end edge and a second end edge opposite the first end edge. The edges of the connector body are configured to pass through the opening in the support wall such that the front side is forward of the first surface of the support wall and the rear side is rearward of the first surface of the support wall. The connector body has contact channels therethrough between the front side and the rear side. the contact channels hold contacts in corresponding contact channels. The contacts are presented along the front side for engaging corresponding mating contacts of a mating connector. The front side faces in a mating direction along a mating axis. The contacts are spring biased within the contact channels for mating with the mating contacts. The contacts have cables terminated thereto extending rearward from the connector module. The connector assembly includes a mounting frame having a passage extending between a mating side and a mounting side of the mounting frame that face in opposite directions. The mounting frame has a first side wall, a second side wall opposite the first side wall, and an end wall between the first side wall and the second side wall. The mounting frame has a window between the first side wall and the second side wall opposite the end wall. The window is open to and provides access to the passage. The passage receives the connector body of the connector module through the window in a direction generally perpendicular to the mating axis. The mounting side faces in a mounting direction and is configured to interface with the first surface of the support wall. The mounting frame includes a connector module support structure for supporting the connector module in the passage of the mounting frame. The connector module support structure defines a confined space oversized relative to the connector body of the connector module to allow a limited amount of floating movement in the confined space. The connector module support structure includes a first side blocking surface defined by the first side wall, a second side blocking surface defined by the second side wall, and a first end blocking surface defined by the first end wall. The first side blocking surface cooperates with the second side blocking surface to confine movement of the connector module in a first lateral direction to a limited amount of floating movement in the first lateral direction within the passage. The first end blocking surface cooperates with the support wall edge of the support wall to confine movement of the connector module in a second lateral direction to a limited amount of floating movement in the second lateral direction within the passage.
In another embodiment, a connector assembly is configured to be mounted to a support wall.

Embodiments set forth herein include connector assemblies and communication systems that include such connector assemblies. The communication system may include, for example, a circuit board that is secured to the connector assembly. In some embodiments, the communication system is a backplane (or midplane) communication system. As used herein, the terms backplane and midplane are used interchangeably and represent a system interface for multiple daughter card assemblies (e.g., line cards or switch cards). In other embodiments, the communication system is a circuit board assembly (e.g., daughter card assembly). In other embodiments, the communication system is a fiber optic communication system. One or more embodiments permit a connector module of the connector assembly to float during a mating operation. One or more embodiments enable using a denser grouping of contacts.
As used herein, phrases such as “a plurality of [elements],” “a set of [elements],” “an array of [elements],” and the like, when used in the detailed description and claims, do not necessarily include each and every element that a component may have. For instance, the phrase “the connector module having a plurality of contacts that include [a recited feature]” does not necessarily mean that each and every contact of the connector module has the recited feature. Instead, only some of the contacts may have the recited feature and other contacts of the connector module may not include the recited feature. As another example, the detailed description or the claims may recite that a connector assembly includes “cable assemblies, each of which including a [recited feature].” This phrase does not exclude the possibility that other cable assemblies of the connector assembly may not have the recited feature. Accordingly, unless explicitly stated otherwise (e.g., “each and every cable assembly of the connector module”), embodiments may include similar elements that do not have the same features.
In some applications, the connector assemblies 100, 300 may be referred to more generally as a circuit board assemblies. The communication system 10 may be configured for radiofrequency (RF) applications. In particular embodiments, the communication system 10 and/or its components, such as the connector assembly 100 and/or 300, are configured to satisfy military and aerospace applications. For example, the components of the communication system 10 may be configured to satisfy one or more industry or government standards, such as MIL-STD-348. To illustrate one example of the communication system 10, the connector assemblies 100, 300 may form an interconnect between analog and digital sections of a radio. The connector assembly 300 may perform analog functions. The connector assembly 300 may be replaced with other connector assemblies that are configured to perform the same or different operations. The digital functions, including digital signal processing, may be performed by a communication component (not shown) that is coupled to the connector assembly 100. The other communication component may be another daughter card assembly (not shown).
The communication system 10 and/or its components (e.g., the connector assembly 100 and/or 300) may be configured to satisfy one or more industry or government standards. By way of example only, embodiments may be configured to satisfy the VME International Trade Association (VITA) standards (e.g., VITA 48, VITA 67, et al.). The communication system 10 and/or its components may have an operating speed that achieves 50 GHz or greater. In particular embodiments, the communication system 10 and/or its components may achieve an operating speed of 60 GHz or greater. It should be understood, however, that other embodiments may be configured for different standards and may be configured to operate at different speeds. In some configurations, embodiments may be configured to operate within the range of DC to 60.0 GHz.
In an exemplary embodiment, the connector assembly 300 is a daughter card assembly having a connector module 302 and a substrate 306. The connector module 302 is mounted to the substrate 306. The substrate 306 may be a circuit card, such as a daughter card. The connector assembly 300 includes a guide module 308 mounted to the substrate 306 proximate to the connector module 302. The guide module 308 is used to guide mating with the connector assembly 100. In the illustrated embodiment, the guide module 308 includes an opening configured to receive an alignment pin. The opening may be chamfered or have a lead-in. Other types of guide features may be used in alternative embodiments, such as a guide post. In the illustrated embodiment, the connector module 302 is a right-angle connector module having the substrate 306 oriented perpendicular to the mating face of the connector module 302. The substrate 306 is oriented perpendicular to the substrate of the connector assembly 100. However, other orientations are possible in alternative embodiments. For example, the connector module 302 may be a mezzanine connector having the substrate 306 oriented parallel to the mating face and parallel to the substrate of the connector assembly 100.
The connector module 302 includes a connector body 310 holding cable assemblies 320. The connector body 310 extends between a mating end 312 and a mounting end 314. Optionally, the mounting end 314 may be oriented perpendicular to the mating end 312. The mounting end 314 is mounted to the substrate 306. In the illustrated embodiment, the mating end 312 is oriented perpendicular to the substrate 306. The connector body 310 includes a plurality of contact channels 316 receiving corresponding cable assemblies 320. The connector body 310 includes alignment features 318 for aligning the connector module 302 with the connector assembly 100 during mating. In the illustrated embodiment, the alignment features 318 are openings and may be referred to hereinafter as openings 318. Other types of alignment features may be provided in alternative embodiments. The openings 318 may be arranged to provide keyed mating with the connector assembly 100.
Each cable assembly 320 includes a cable 322 and a contact 324 terminated to the end of the cable 322. The contact 324 has a mating end 326 for mating with the coaxial connector assembly 100. In various embodiments, the contact 324 is a coaxial contact; however, other types of contacts may be provided in alternative embodiments, such as pin contacts, socket contacts, fiber optic contacts (for example, fiber optic ferrules), and the like. In an exemplary embodiment, the coaxial contact 324 is an RF contact. The coaxial contact 324 includes an inner contact 330 and an outer contact 332 surrounding the inner contact 330. The inner contact 330 is configured to be terminated to a conductor of the cable 322. The outer contact 332 is configured to be terminated to a shield, such as a cable braid, of the cable 322. Other arrangements are possible in alternative embodiments. In alternative embodiments, the connector assembly 300 does not include the cables 322 that directly couple to the contacts 324. For example, the contacts 324 may directly terminate to the substrate 306 (for example, the daughtercard) and/or may be communicatively coupled to cables through traces and vias (not shown) of the substrate 306.
For reference, the connector assembly 100 is oriented with respect to mutually perpendicular axes 191-193, which includes a mating axis 191, a first lateral axis 192, and a second lateral axis 193 (the connector assembly 300 is illustrated in
The connector assembly 100 includes a connector module 102 and a mounting frame 104 that are operably coupled to each other. The connector module 102 is mounted to a support wall 110. The support wall 110 may be, for example, a circuit board (for example, a backplane circuit board), a panel, or another type of wall. The mounting frame 104 is used to secure the connector module 102 to the support wall 110. In an exemplary embodiment, the mounting frame 104 is slightly oversized relative to the connector module 102 such that the connector module 102 has a limited amount of floating movement relative to the mounting frame 104, such as for alignment with the connector assembly 300 during mating. During operation or usage of the connector assembly 100, a portion of the connector module 102 is floatably held in the mounting frame 104, to allow relative movement between the support wall 110 and the connector module 102. For example, the connector module 102 is permitted to move laterally (e.g., in a lateral direction) during a mating operation (for example, parallel to the plane of the support wall 110). The lateral direction may be parallel to the first lateral axis 192 or parallel to the second lateral axis 193. However, it should be understood, that the lateral direction may be any direction that is perpendicular to the mating axis 191 or parallel to a plane defined by the first and second lateral axes 192, 193.
The mounting frame 104 includes opposite mating and mounting sides 106, 108. More specifically, the mating side 106 is configured to face in a mating direction (for example, forward) along the mating axis 191, and the mounting side 108 is configured to face in a mounting direction (for example, rearward) along the mating axis 191 that is opposite the mating direction. The mounting frame 104 has a thickness 114 that is defined between the mating and mounting sides 106, 108. The mounting frame 104 has an outer frame edge defined by a first side wall 116, a second side wall 117 opposite the first side wall 116, a first end wall 118, and a window 119 opposite the first end wall 118. The window 119 extends between the first and second side walls 116, 117. The first and second side walls 116, 117 extend between the first end wall 118 and the window 119. In the illustrated embodiment, the mounting frame 104 has a substantially rectangular profile, but the mounting frame 104 may have profiles with other shapes in alternative embodiments. In an exemplary embodiment, the mounting frame 104 is U-shaped defined by the side walls 116, 117 and the end wall 118.
In an exemplary embodiment, the mounting frame 104 includes a passage 120 that extends through the mating and mounting sides 106, 108. The window 119 is open to and provides access to the passage 120. The window 119 is sized and shaped to receive the connector module 102. For example, the connector module 102 may be side loaded into the passage 120 through the window 119 and/or the mounting frame 104 may be side-loaded onto the connector module 102. The passage 120 is sized and shaped to receive a portion of the connector module 102. For example, the mounting frame 104 includes a front edge 122 (
In an exemplary embodiment, the mounting frame 104 includes a connector module support structure 200 used to support the connector module 102 relative to the mounting frame 104. For example, the connector module support structure 200 includes blocking surfaces (described below) that engage the connector module 102 and retain the connector module 102 in the mounting frame 104. The connector module support structure 200 prevents the connector module 102 from passing freely through the passage 120. The connector module support structure 200 may also prevent the connector module 102 from moving laterally beyond a confined space. For example, the connector module support structure 200 forms boundaries that define a limited amount of floating movement of the connector module 102 relative to the mounting frame 104. In an exemplary embodiment, the connector module support structure 200 includes support elements, such as support pins (described below) to support the connector module 102 relative to the mounting frame 104. The support pins may cooperate with the blocking surfaces to confine the connector module 102 in the passage 120 relative to the support wall 110. In other various embodiments, the support wall 110 may form part of the connector module support structure 200. For example, the connector module 102 may engage the support wall 110 to locate the connector module 102 within the passage 120.
The connector module 102 includes a connector body 126 having a front side 127 and a rear side 129 (
The connector body 126 holds the contacts 132 at designated positions for engaging corresponding contacts 324. In the illustrated embodiment, the contacts 132 are elements of corresponding cable assemblies 128. The contacts 132 represent mating ends of the corresponding cable assemblies 128. In the illustrated embodiment, each of the contacts 132 includes a signal element 134 and a ground element 136 that is coaxially aligned with the signal element 134; however, other types of contacts may be used in alternative embodiments. The signal and ground elements 134, 136 may be electrically coupled to signal and ground paths (not shown) through cables 131 of the cable assemblies 128. The signal element 134 may be a center contact 134 and the ground element 136 may be an outer contact 136. In alternative embodiments, the connector assembly 100 does not include the cables 131 that directly couple to the contacts 132. For example, the contacts 132 may directly terminate to a substrate (not shown).
The mounting frame 104 may include a frame extension 138. The frame extension 138 represents a section of the mounting frame 104 that extends laterally away from the passage 120. For example, the frame extension 138 may extend from the first end wall 118 away from the passage 120. The frame extension 138 is configured to interface with the support wall 110. For example, the mounting frame 104 may include posts extending from the mounting side 108 that are received in corresponding openings in the support wall 110 to orient the mounting frame 104 relative to the support wall 110. The frame extension 138 includes one or more through holes 139 that are sized and shaped to receive hardware (e.g., screws, bolts, plugs, and the like) for securing the mounting frame 104 to the support wall 110. In some embodiments, the through holes 139 may be defined by threaded surfaces of the mounting frame 104 for engaging screws. In other embodiments, the surfaces that define the through holes 139 are not threaded. The mounting frame 104 is configured to have a fixed position relative to the support wall 110. The connector module 102, on the other hand, is permitted to float relative to the support wall 110 within the confined space.
In an exemplary embodiment, the connector assembly 100 has a footprint relative to the support wall 110. The footprint is the outer perimeter of the connector assembly 100 on the surface of the support wall 110. The footprint may be defined by the mounting frame 104. In various embodiments, a portion of the footprint is defined by the connector module 102. For example, because the second end of the mounting frame 104 is open and includes the window 119, the second end of the footprint may be defined by the connector module 102, which may be flush with the second end of the mounting frame 104 or which may extend beyond the second end of the mounting frame 104. By reducing the size of the mounting frame 104, and not entirely circumferentially surrounding the connector module 102 (for example, by having the U-shaped, open end), the overall footprint of the connector assembly 100 is smaller. The weight of the connector assembly 100 may be less by removing the second end of the mounting frame 104 and having the second end open. The contacts 132 are configured to be positioned closer to the edge of the footprint by eliminating a second end wall of the mounting frame 104, which allows greater spacing, or pitch, between the contacts 132 and/or allows a greater number of contacts 132 within the footprint.
The connector body 126 includes a forward section 140 and a rear section 142. In an exemplary embodiment, the forward and rear sections 140, 142 are discrete elements that are configured to be secured to each other, such as using hardware (e.g., screws), but may be secured to each other in other manners in alternative embodiments. The forward section 140 includes a main portion 144 and a flange portion 145 that extends laterally (or radially) away from the main portion 144. In an exemplary embodiment, the flange portion 145 includes a side flange defined by a first lip 146 and a side flange defined by a second lip 147 at opposite first and second sides 141, 143 of the connector body 126. The flange portion 145 may include other flange sections, such as an end flange (not shown) at a first end 149 of the connector body 126. In an exemplary embodiment, the flange portion 145 is provided at the front side 127 of the connector body 126. The lips 146, 147 include forward facing surfaces, rearward-facing surfaces, and outward facing surfaces. The forward facing surfaces and/or the rearward-facing surfaces and/or the outward facing surfaces may be used for locating the connector module 102 within the mounting frame 104. For example, the forward facing surfaces and rearward-facing surfaces may be used for locating the connector module 102 in the mating direction along the mating axis 191 and the outward facing surfaces may be used for locating the connector module 102 in one or more lateral directions, such as along the first lateral axis 192 and/or the third lateral axis 193.
The mounting frame 104 includes one or more channels 150 that receive the lips 146, 147. For example, the mounting frame 104 includes a first side wall channel 156 along the first side wall 116 and a second side wall channel 157 along the second side wall 117. The mounting frame may include a first end wall channel (not shown) along the first end wall 118. The channels 156, 157 are open to the passage 120. The channels 156, 157 are sized and shaped to receive the lips 146, 147. In an exemplary embodiment, the channels 150 each include a front rim 153 at the mating side 106 and a rear rim 155 at the mounting side 108. The channels 150 each include an outer wall 154 between the front rim 153 and the rear rim 155. The front rim 153, the rear rim 155, and the outer wall 154 define portions of the connector module support structures 200.
The connector module support structure 200 includes blocking surfaces 160 used to block or retain the connector module 102 in the mounting frame 104. In an exemplary embodiment, the front rim 153, the rear rim 155, and the outer wall 154 define blocking surfaces 160. The blocking surfaces 160 may limit or restrict movement of the connector module 102 in an axial direction along the mating axis 191 (for example, the front rim 153 and the rear rim 155 may restrict movement along the mating axis 191). The blocking surfaces 160 may limit or restrict movement of the connector module 102 in a lateral direction along the lateral axis 192 and/or the lateral axis 193 (for example, the outer wall 154 may restrict movement along the lateral axis 192 or the lateral axis 193). The mounting frame 104 may include additional blocking surfaces 160 in alternative embodiments. Other structures may form connector module support structures 200 that cooperate with the blocking surfaces 160 to confine movement of the connector module 102 within the mounting frame 104.
In an exemplary embodiment, the blocking surfaces 160 include front blocking surfaces 161, rear blocking surfaces 162 and end blocking surfaces 163. The front blocking surfaces 161 limit or restrict movement in the mating direction. The rear blocking surfaces 162 limit or restrict movement in the mounting direction. The end blocking surfaces 163 limit or restrict movement in one or more lateral directions. In an exemplary embodiment, the front rims 153 define the front blocking surfaces 161, the rear rims 155 defines the rear blocking surface 162 and the outer walls 154 define the end blocking surfaces 163. The end blocking surfaces 163 face in the lateral direction that is perpendicular to the mating axis 191 to limit or restrict movement in the lateral direction. In an exemplary embodiment, the passage 120 and the channels 150 are oversized relative to the connector module 102 to allow a limited amount of floating movement of the connector module 102 within the mounting frame 104, such as in the lateral direction. For example, the end blocking surfaces 163 may be wider than the connector body 126 at the flange portion 145 to allow shifting in at least one of the lateral directions 192, 193. Gaps may be provided between the lips 146, 147 and the outer walls 154 to allow the confined and limited amount of floating movement. In various embodiments, the end blocking surfaces 163 may permit the connector module 102 to float at least 0.15 mm along a lateral plane. In various embodiments, the connector module 102 may be permitted to float at least 0.25 mm or, more particularly, at least 0.35 mm along the lateral plane. It should be understood, however, that the connector assembly 100 may be configured to permit a greater or lesser amount of floating than the values provided above. The amount of floating movement may be controlled based on manufacturing tolerances of the connector assemblies 100, 300.
The lips 146, 147 of the flange portion 145 are configured to be retained or trapped between the front and rear rims 153, 155 of the mounting frame 104. The blocking surfaces 160 may limit axial movement along the mating axis 191. Optionally, the connector module 102 may have a limited amount of floating movement in the mating axial direction between the front and rear rims 153, 155. Alternatively, the lips 146, 147 may have a tight fit between the front and rear rims 153, 155 such that there is no movement in the mating axial direction.
The forward section 140 includes a plurality of contact cavities 172, and the rear section 142 includes a plurality of contact cavities 182. When the forward and rear sections 140, 142 are coupled to each other, the contact cavities 172 of the forward section 140 and the contact cavities 182 of the rear section 142 align with each other to form contact channels 184. Each of the contact channels 184 is configured to receive a portion of a corresponding cable assembly 128 and, in particular, a corresponding contact 132. Optionally, the contact cavities 182 may open to an outer edge to define open-sided slots sized and shaped to receive the cables 131 of the cable assemblies 128. In an exemplary embodiment, the rear section 142 is used to support the springs 186 of the cable assemblies 128. The contacts 132 may be compressed rearward against the springs 186 during mating with the mating connector module 302 (shown in
In an exemplary embodiment, the connector module 102 includes alignment posts 176 that extend forward from the of the front side 127 of the connector body 126 in the mating direction. The alignment posts 176 are configured to engage the connector module 302 (
In an exemplary embodiment, the support pin 202 includes a head 210 and a base 212 opposite the head 210. The base 212 may be threaded such that the support pin 202 may be threadably coupled to the connector body 126 of the connector module 102. In an exemplary embodiment, the support pin 202 is a shoulder screw having a shoulder 214 between the head 210 and the base 212. The shoulder 214 is configured to bottom out against the connector body 126. The support pin 202 has a length between the head 210 and the shoulder 214 that is longer than a thickness of the first end wall 118 leading to a gap 216 between the first end 149 of the connector body 126 and the first end wall 118; and/or a gap 218 between the head 210 and the first end wall 118.
The connector body 126 includes a first slot 220 that receives the base 212 of the support pin 202. For example, the first slot 220 is provided at the first end 149 of the connector body 126. The first slot 220 may be threaded to threadably receive the base 212 of the support pin 202. The mounting frame 104 includes a second slot 222 that receives the shaft of the support pin 202. For example, the second slot 222 is provided at the first end wall 118 of the mounting frame 104. In various embodiments, the mounting frame 104 includes a pocket 224 open to the second slot 222. The pocket 224 receives the head 210 of the support pin 202. In an exemplary embodiment, the second slot 222 is elongated (for example, side-to-side) to allow the support pin 202 to move within the second slot 222. For example, the second slot 222 may be elongated in a lateral direction, such as along the lateral axis 192. The pocket 224 may be elongated to allow the head 210 to move laterally within the pocket 224. The amount of oversizing of the second slot 222 and/or the pocket 224 may define the amount of floating travel of the support pin 202 and the connector module 102 relative to the mounting frame 104. For example, the first end wall 118 defines blocking surfaces that restrict or define the amount of floating movement of the connector module 102 relative to the mounting frame 104.
Gaps 226 are provided between the support pin 202 and the mounting frame 104 to define the amount of floating movement. Gaps 228 are provided between the side lips 146, 147 and the side walls 116, 117, such as between the side lips 146, 147 and the outer walls 154 of the channels 156, 157. The gaps 226, 228 allow relative movement of the connector module 102 and the mounting frame 104. In an exemplary embodiment, the support pin 202 is used to block or restrict movement in a first direction (for example, through the window 119) and the end wall 118 is used to block or restrict movement in a second direction opposite the first direction. The side walls 116, 117 block or restrict movement in third and fourth directions perpendicular to the first and second directions. As such, the mounting frame 104 confines movement in three directions and the support pin 202 confines movement in the fourth direction.

For example, the connector module 802 is permitted to move in a lateral direction during a mating operation (for example, parallel to the plane of the support wall 810). In an exemplary embodiment, the support wall 810 cooperates with the mounting frame 804 to confine and limit the amount of floating movement relative to the mounting frame 804. For example, the support wall 810 blocks movement in one direction and the mounting frame 804 blocks movement in three directions. The support wall 810 is used for confining movement in one direction in lieu of using a support pin, such as the support pin 202 (shown in

The blocking surfaces 860 may limit or restrict movement of the connector module 802 in an axial direction along the mating axis. The blocking surfaces 860 may limit or restrict movement of the connector module 802 in a lateral direction. In an exemplary embodiment, the blocking surfaces 860 are defined by the end wall 818 and the side walls 816, 817, such as the channels 850. The mounting frame 804 may include additional blocking surfaces 860 in alternative embodiments.
In an exemplary embodiment, the support wall 810 defines a blocking surface cooperating with the blocking surfaces 860 (shown in
The support pin 902 is received in a slot 904 in the side wall 816 or the side wall 817 of the mounting frame 804, as compared to the end wall 818. The connector body 826 of the connector module 802 includes a slot 906 that receives the support pin 902. The slot 906 is elongated relative to the support pin 902 allowing the connector module 802 to move in a lateral direction relative to the support pin 902. The amount of oversize of the slot 906 defines the limited amount of floating movement of the connector module 802 relative to the mounting frame 804 in the lateral direction. Optionally, support pins 902 may be provided on both sides.
