The subject matter herein relates generally to electrical connectors and, more particularly, to connectors that include contacts that mate with one another.
Known connectors include contacts disposed within or coupled with a housing. The housings mate with one another to electrically couple the contacts. Once the contacts are joined with one another, the connectors communicate data signals and/or power between each other via the coupled contacts. Some known connectors include contacts that mate with contact pads of another connector. For example, a connector system may include a first connector that includes several contacts while a second connector includes several substantially flat contact pads. By way of example only, the second connector may be a printed circuit board that includes contact pads disposed on one side of the board. The contacts engage the contact pads to electrically couple the contacts with the contact pads.
The contact pads may include or be formed from metals or metal alloys that may develop an insulating layer of surface contamination when exposed to the environment over time. This layer may be present on the surface of the contact pads that mate with the first connector. The layer may negatively impact the coupling between the connector and the contact pads. For example, the layer may have a greater resistivity than the contact pad and increase the resistance of the coupling between the contacts and the contact pads.
In order to improve the electrical coupling between the contacts and the contact pads, the layer of surface contamination may be locally removed from the contact pad by laterally moving the contact across the surface of the contact pad. The lateral movement of the contact may scrape off or otherwise remove the layer of surface contamination from a portion of the contact pad. The contact engages the contact pad where the layer has been removed for an improved electrical coupling between the contact and the contact pad.
But, with some known connectors, in order to laterally move the contact across the contact pad and remove the layer of surface contamination, the connector in which the contact is disposed must be laterally moved with respect to the connector that includes the contact pad. In some applications, there is insufficient room to laterally move the connectors relative to each other. Additionally, lateral movement of the connectors relative to each other may result in misalignment of the contacts relative to the contact pads. Such misalignment may prevent some of the contacts from mating with the contact pads.
A need exists for a connector that mates a contact with a conductive pad of another connector while removing a layer of surface contamination from the conductive pad. Removing the layer of surface contamination may improve the electrical coupling between the contact and the conductive pad by reducing the resistance of the conductive pathway that extends between the contact and the conductive pad.
In one embodiment, a connector is provided. The connector includes a housing, a contact, an angled interface, and a resilient member. The housing includes a front end with a channel inwardly extending from the front end. The contact is disposed in the channel and is elongated along a longitudinal axis. The contact includes a mating end and an interface end. The angled interface is slidably coupled to the interface end of the contact. The angled interface includes a sliding surface that is oriented at an oblique angle with respect to the longitudinal axis. The resilient member is coupled with the contact and the housing and is configured to apply a force to the contact in a direction that is angled with respect to the longitudinal axis. The mating end of the contact engages a conductive element of a mating connector and the interface end of the contact slides along the sliding surface of the angled interface when the contact is moved in a mating direction toward the conductive element. The angled interface translates movement of the contact in the mating direction into lateral movement with respect to the mating direction across the conductive element.
In another embodiment, another connector is provided. The connector includes a housing, a contact, and an angled interface. The contact is coupled with the housing and includes a mating end and an interface end. The angled interface is disposed within the housing and is arranged for sliding engagement with the interface end of the contact. When the housing is moved in a mating direction toward a mating connector and the mating end of the contact engages a conductive element of the mating connector, further movement of the housing in the mating direction causes the interface end of the contact to slidably move along the angled interface. The angled interface imparts translational movement of the contact with respect to the housing and the mating end of the contact moves laterally across the conductive element.
In another embodiment, another connector is provided. The connector includes a body, a mating array including a contact, and a rotating arm. The rotating arm couples the mating array with the body and rotates toward the body when the body is moved toward a mating connector and the contact engages a conductive element of the mating connector. The rotating arm translates movement of the body toward the mating connector into lateral movement of the mating array and contact. The contact laterally wipes across the conductive element of the mating connector.
The contacts 106 engage corresponding conductive elements 108 of the second connector 104. The contact 106 and the conductive element 108 include, or are formed from, conductive materials, such as metals or metal alloys. In one embodiment, the contacts 106 of the first connector 102 are elongated contacts. Alternatively, the contacts 106 may be non-elongated contacts. For example, the contacts 106 may not be elongated in a mating direction 110 that the first connector 102 and/or second connector 104 are moved relative to each other. The second, or mating, connector 104 may be a circuit board, such as a printed circuit board (PCB), with the conductive elements 108 being contacts that mate with the contacts 106. The conductive elements 108 may be substantially flat contact pads disposed on one side of the circuit board. The number of conductive elements 108 is shown merely as an example. Alternatively, the second connector 104 may be a connector other than a circuit board.
The connectors 102, 104 mate with one another by moving the first connector 102 toward the second connector 104 in the mating direction 110 or by moving the second connector 104 in a direction that is opposite of the mating direction 110 until the contacts 106 of the first connector 102 engage the conductive elements 108 of the second connector 104. For example, at least one of the connectors 102, 104 is moved toward the other of the connectors 102, 104. As shown in
When the connectors 102, 104 mate with one another, the contacts 106 are caused to move laterally across the conductive elements 108 as will be explained in more detail hereinbelow. For example, as shown in
The contacts 106 may move in the wiping directions 200A, 200B independent of the movement of the connector 102 to prevent misalignment of the contacts 106 with the conductive elements 108. For example, if the contacts 106 were able to laterally move across the conductive elements 108 only if the connector 102 also moved in the wiping direction 200A or 200B, then the contacts 106 may become misaligned with the conductive elements 108. The independent lateral movement of the contacts 106 permits an operator to align the connectors 102, 104 with one another along the mating direction 110 while still achieving a wiping motion of the contacts 106 across the conductive elements 108 in the wiping directions 200A, 200B.
The wiping movement of the contacts 106 across the conductive elements 108 may improve an electrical coupling between the contacts 106 and conductive elements 108. For example, the wiping movement of the contacts 106 across the conductive elements 108 may remove one or more layers of surface contamination on the conductive elements 108. Removal of the surface contamination may reduce the resistivity of the coupling between the contacts 106 and conductive elements 108.
As shown in
The openings 700 have a width dimension 702 in a direction that is angled with respect to the corresponding wiping direction 200A or 200B. For example, the width dimension 702 may extend in a direction that is perpendicular to the wiping direction 200A or 200B of the contact 106 in the channel 310. The width dimension 702 may be sufficiently large to permit movement of the contacts 106 in the wiping direction 200A or 200B, but small enough to constrain movement of the contacts 106 to the wiping direction 200A or 200B. For example, the width dimension 702 may be slightly larger than a width dimension 708 of the contacts 106 to permit movement of the contacts 106 in the wiping directions 200A, 200B yet prevent significant movement of the contacts 106 in directions that are angled with respect to the wiping directions 200A, 200B.
The front end 114 of the housing 112 opposes the interconnecting wall 316. The contact 106 may be an elongated contact that extends from an interface end 302 to a mating end 300 along the longitudinal axis 304. Alternatively, the contact 106 may be a non-elongated contact. For example, the contact 106 may not be longer between the interface end 302 and the mating end 300 than in another direction. While the mating end 300 is shown as a rounded tip, alternatively the mating end 300 may have a different shape. The illustrated interface end 302 includes sides 306, 308 that are angled with respect to one another. For example, the sides 306, 308 may be approximately planar surfaces that are obliquely or perpendicularly oriented with respect to each other. The sides 306, 308 also are angled with respect to the longitudinal axis 304. In the illustrated embodiment, the sides 306, 308 are oriented at approximately 45 degrees with respect to the longitudinal axis 304. In another embodiment, one or more of the sides 306, 308 may be oriented at a different angle with respect to the longitudinal axis 304. Alternatively, the interface end 302 includes only the side 306. In another embodiment, the interface end 302 may be rounded in a manner similar to the mating end 300.
The channel 310 includes an angled interface 318 that is angled with respect to the longitudinal axis 304 of the contact 106. For example, the angled interface 318 may include a sliding surface 320 that is obliquely oriented with respect to the longitudinal axis 304. The sliding surface 320 may be oriented at an angle 328 with respect to the longitudinal axis 304. As shown in
The angled interface 318 is slidably coupled with the interface end 302 of the contact 106. For example, the angled interface 318 may slidably engage one of the sides 306, 308 of the interface end 302. The interface end 302 may remain electrically coupled with the angled interface 318 while the interface end 302 slides along the angled interface 318. For example, a conductive pathway that communicates data and/or power between the connectors 102, 104 via the contact 106 may extend across the interface between the sliding surface 320 and the interface end 302 of the contact 106. In the illustrated embodiment, the side 306 of the contact 106 includes a coating 322 that is disposed between the side 306 and the angled interface 318. The coating 322 may include, or be formed from, one or more conductive materials. The coating 322 may be formed of a material that reduces the coefficient of friction between the side 306 and the sliding surface 320 to permit the interface end 302 to slide more easily along the angled interface 318.
As shown in
The movement of the contact 106 in the sliding direction 400 laterally displaces the contact 106 with respect to the conductive element 108. As shown in
In one embodiment, the connector 102 includes a resilient member 324 that is coupled with the contact 106. The resilient member 324 may be joined to the contact 106 between the ends 300, 302. While the resilient member 324 is perpendicularly oriented with respect to the longitudinal axis 304, alternatively the resilient member 324 may be obliquely oriented with respect to the longitudinal axis 304. The resilient member 324 is a body that applies a force 404 (shown in
The resilient member 324 is compressed between the contact 106 and the interior wall 326 when the contact 106 moves in the wiping direction 200A from the initial position 118 (shown in
The connector 102 may be decoupled from the connector 104 by moving the connector 102 in a direction opposite of the mating direction 110. As the connector 102 is retreated away from the connector 104 and the contact 106 is retreated away from the conductive element 108, the compressed resilient member 324 continues to apply the force 404 on the contact 106. The resilient member 324 may apply the force 404 until the resilient member 324 is no longer compressed, or until the contact 106 is returned to the initial position 118. The application of the force 404 pushes the contact 106 in a lateral direction that opposes the wiping direction 200A. For example, as the force 404 is applied to the contact 106, the interface end 302 of the contact 106 may slide down the angled interface 318 in a direction that opposes the sliding direction 400. For example, the contact 106 may slide along the angled interface 318 from the position shown in
As shown in
The angled interface 522 is slidably coupled with the interface end 516 of the contact 500. The interface end 516 may remain electrically coupled with the angled interface 522 while the interface end 516 slides along the angled interface 522. In the illustrated embodiment, the side 518 includes a coating 526 that may be similar to the coating 322 (shown in
One difference between the contacts 106 (shown in
The sections 504, 506 of the contact 500 may be interconnected by a normal resilient member 528. In the illustrated embodiment, the normal resilient member 528 is disposed within the gap between the sections 504, 506. Alternatively, the normal resilient member 528 may be located within the contact 500. For example, one of the sections 504, 506 may telescope within the other of the sections 504, 506 along the longitudinal axis 508 with the normal resilient member 528 disposed between the sections 504, 506. The normal resilient member 528 is a body that applies a force 540 on the mating section 506 when the normal resilient member 528 is compressed. For example, the normal resilient member 528 may be a spring disposed within the contact 500 between the sections 504, 506. The normal resilient member 528 may provide a force on the mating section 506 in a direction parallel to the mating direction 110 to ensure that the mating end 510 remains engaged with the conductive element 108 during mating of the connectors 102, 104. For example, after the mating end 510 engages the conductive element 108 during mating of the connectors 102, 104, movement of the connector 102 in the mating direction 110 relative to the connector 104 may displace the sections 504, 506 toward one another while also sliding the contact 500 in the wiping direction 200A. The displacement of the sections 504, 506 toward one another compresses the normal resilient member 528.
As the normal resilient member 528 is compressed, the normal resilient member 528 exerts a mating force 540 on the mating section 506 in a direction parallel to the mating direction 110 to push the mating section 506 along the mating direction 110. The mating force 540 may ensure engagement between the mating end 510 and the conductive element 108 as the contact 500 wipes across the conductive element 108 in the wiping direction 200A. For example, the mating force 540 may push the mating section 506 along the mating direction 110 to maintain contact between the mating end 510 and the conductive element 108 as the contact 500 wipes across the conductive element 108.
In the position shown in
The cam 816 pivots about the pin 818 when the mating end 810 of the contact 800 engages the conductive element 108. The pivoting of the cam 816 translates movement of the contact 800 and the connector 802 in the mating direction 902 into lateral movement of the contact 800 in the wiping direction 904 across the conductive element 108. The spring 822 imparts a restoring force on the cam 816 that causes the cam 816 to pivot about the pin 818 in an opposite direction when the connector 802 moves away from the connector 104. Alternatively, the resilient conductive member 814 provides the restoring force.
The lateral movement of the mating end 810 across the conductive element 108 in the wiping direction 904 may remove one or more layers of surface contamination on the conductive element 108 to improve the electrical coupling of the contact 800 with the conductive element 108. When the connector 802 is decoupled from the connector 104, the spring 822 may restore the contact 800 from the position of the contact 800 shown in
The contact 1000 is elongated along a longitudinal axis 1028. The angled interface 1006 may include a sliding surface 1030 that is obliquely oriented with respect to the longitudinal axis 1028. The sliding surface 1030 may be oriented at an angle 1032 with respect to the longitudinal axis 1028. As shown in
Prior to mating the contact 1000 with the conductive element 108, the longitudinal axis 1028 is in an initial position 1026 that is laterally spaced apart from the center axis 120 of the conductive element 108. As the connector 1002 moves in a mating direction 1024 toward the conductive element 108, the contact 1000 slides along the sliding surface 1030 of the angled interface 1006 to wipe across the conductive element 108, similar to as described above. The connector 1002 includes an angled slot 1016 that extends into the channel 1004. The contact 1000 includes a lateral pin 1018 that is received in the slot 1016. While the pin 1018 is described in terms of an elongated pin, alternatively the pin 1018 may be a bearing or other mechanism that reduces friction between the contact 1000 and the connector 1002 when the pin 1018 moves through the slot 1016. The pin 1018 moves within the slot 1016 to guide the contact 1000 in corresponding directions. For example, the pin 1018 may move in a first direction 1020 in the slot 1016 when the contact 1000 is moved toward the conductive element 108 to guide the contact 1000 within the channel 1004. The contact 1000 may move such that the longitudinal axis 1028 moves toward the center axis 120 of the conductive element 108. The contact 1000 may move such that the longitudinal and center axes 1028, 120 are aligned. Alternatively, the contact 1000 may move such that the longitudinal and center axes 1028, 120 are not aligned.
The pin 1018 may move in an opposite second direction 1022 in the slot 1016 when the contact 1000 is moved away from the conductive element 108 to guide the contact 1000 in the channel 1004. The movement of the pin 1018 within the slot 1016 may prevent the contact 1000 from being misaligned within the channel 1004 as the contact 1000 engages and disengages the conductive element 108. A spring or other resilient member (not shown) similar to the resilient member 324 (shown in
The angled interface 1108 may be electrically coupled with a source or recipient (not shown) of the data and/or power. The contact 1100 is elongated along a longitudinal axis 1106 between a mating end 1110 and an interface end 1112. The interface end 1112 includes a resilient conductive member 1114. The conductive member 1114 may be a wire or a spring such as an elongated torsion or return spring. The angled interface 1108 may include a sliding surface 1122 that is obliquely oriented with respect to the longitudinal axis 1106. The sliding surface 1122 may be oriented at an angle 1124 with respect to the longitudinal axis 1106. As shown in
The contact 1100 includes a rotating member 1116 disposed at or near the interface end 1112. The rotating member 1116 may be a cylindrical body that rotates about a post 1118. Alternatively, the rotating member 1116 may be a different body that rotates relative to the contact 1100. Similar to as described above, the contact 1100 moves along the sliding surface 1122 of the angled interface 1108 to translate movement of the contact 1100 toward the conductive element 108 of the connector 104 into a lateral wiping movement of the mating end 1110 across the conductive element 108.
Prior to mating the contact 1100 with the conductive element 108, the longitudinal axis 1106 is in an initial position 1120 that is laterally spaced apart from the center axis 120 of the conductive element 108. In the illustrated embodiment, the contact 1100 moves along the sliding surface 1122 of the angled interface 1108 using the rotating member 1116. The rotating member 1116 rotates about the post 1118 to roll along the sliding surface 1122. When the contact 1100 is moved toward and engages the conductive element 108, further movement of the connector 1102 toward the conductive element 108 causes the rotating member 1116 to rotate and roll along the sliding surface 1122.
The rotating member 1116 rolls along the angled interface 1108 and translates the movement of the connector 1102 toward the conductive element 108 into a lateral wiping movement of the mating end 1110 across the conductive element 108. As the rotating member 1116 rolls along the sliding surface 1122, the conductive member 1114 remains engaged with the sliding surface 1122. Alternatively, the rotating member 1116 may be conductive such that the rotating member 1116 electrically couples the contact 1100 with the sliding surface 1122 instead of, or in addition to, the conductive member 1114. For example, the conductive member 1114 may be removed or not provided such that the electrical connection between the contact 1100 and the sliding surface 1122 is provided by the rotating member 1116.
The contact 1100 laterally moves across the conductive element 108 such that the longitudinal axis 1106 of the contact 1100 moves from the initial position 1120 toward the center axis 120 of the conductive element 108. The contact 1100 may move such that the longitudinal and center axes 1106, 120 are aligned. Alternatively, the contact 1100 may move such that the longitudinal and center axes 1106, 120 are not aligned. A spring or other resilient member (not shown) similar to the resilient member 324 (shown in
The angled interface 2706 may include a sliding surface 2734 that is obliquely oriented with respect to the longitudinal axis 2722 of the contact 2700. The sliding surface 2734 may be oriented at the angle 2728 with respect to the longitudinal axis 2722. The angle 2728 may be smaller than the angles 328, 542, 1032, 1124 between the sliding surfaces 320, 524, 1030, 1122 and the longitudinal axes 304, 508, 1028, 1106 of the contacts 106, 500, 1000, 1100, as shown in
In the illustrated embodiment, the connector 2702 includes an opposing angled wall 2738 in the channel 2704 and the contact 2700 includes a guidance shoulder 2740 that protrudes from the contact 2700. The guidance shoulder 2740 may be a collar that projects from the contact 2700. The guidance shoulder 2740 engages the angled wall 2738 when the contact 2700 mates with the conductive element 108 in order to help keep the contact 2700 oriented in the channel 2704. For example, the engagement between the guidance shoulder 2740 and the angled wall 2738 may keep the longitudinal axis 2722 of the contact 2700 oriented perpendicular to the upper surface 2732 of the connector 104 when the contact 2700 laterally moves within the channel 2704.
The contact 2700 may be an elongated contact that extends from an interface end 2718 to a mating end 2720 along a longitudinal axis 2722. Alternatively, the contact 2700 may be a non-elongated contact. While the mating end 2720 is shown as a rounded tip, alternatively the mating end 2720 may have a different shape. The contact 2700 is shown in an initial unmated position in
A resilient member 2730 is disposed between the attachment area 2724 and the interconnecting wall 2714. In the illustrated embodiment, the resilient member 2730 is disposed on the right side of the longitudinal axis 2722 of the contact 2700. For example, the resilient member 2730 and the angled side 2726 may be located on an opposite sides of the longitudinal axis 2722. The resilient member 2730 may be a compression spring or polymer that can be compressed between the interconnecting wall 2714 and the attachment area 2724. In one embodiment, the resilient member 2730 is slightly compressed even when the contact 2700 is unmated from the conductive element 108. Continual compression of the resilient member 2730 may impart a force on the attachment area 2724 of the contact 2700 that keeps the longitudinal axis 2722 of the contact 2700 perpendicular to an upper surface 2732 of the connector 104, such as an upper surface of the printed circuit board to which the conductive element 108 is mounted or joined.
The angled side 2726 of the contact 2700 is slidably coupled with the sliding surface 2734 of the connector 2702. For example, the angled side 2726 may slide along the sliding surface 2734. The angled side 2726 may remain electrically coupled with the sliding surface 2734 while the angled side 2726 slides along the sliding surface 2734. The angled side 2726 of the contact 2700 slides along the sliding surface 2734 as the connector 2702 moves relative to the connector 104 in the mating direction 110 to mate with the connector 104. For example, the connector 2702 is moved toward the connector 104 and/or the connector 104 is moved toward the connector 2702 until the mating end 2720 of the contact 2700 engages the conductive element 108 of the connector 104. Further movement of the connector 2702 toward the connector 104 and/or the connector 104 toward the connector 2702 causes the angled side 2726 of the contact 2700 to slide upward along the sliding surface 2734. As the angled side 2726 of the contact 2700 slides up along the sliding surface 2734, the resilient member 2730 is compressed between the attachment area 2724 and the interconnecting wall 2714 and the contact 2700 moves in the wiping direction 200A. Alternatively, the angled side 2726 of the contact 2700 may slide along the sliding surface 2734 to move in the wiping direction 200B (shown in
The resilient member 2730 may be fixed to the interconnecting wall 2714 and may slide along the attachment area 2724 when the angled side 2726 of the contact 2700 moves along the sliding surface 2734. As described above, the attachment area 2724 may be a relatively low friction surface that allows the resilient member 2730 to remain fixed to the interconnecting wall 2714 while sliding along the attachment area 2724 during movement of the contact 2700 in the channel 2704.
As the contact 2700 moves within the channel 2704 in the wiping direction 200A, the resilient member 2730 is compressed between the interconnecting wall 2714 and the attachment area 2724. The resilient member 2730 is located on the side of the longitudinal axis 2722 that is opposite of the angled side 2726. The resilient member 2730 imparts a force on the contact 2700 when the angled side 2726 of the contact 2700 slides along the sliding surface 2734. When the mating end 2720 of the contact 2700 engages the conductive element 108 and the resilient member 2730 is compressed between the interconnecting wall 2714 and the attachment area 2724 of the contact 2700, the contact 2700 is prevented from rotating in a clockwise direction within the channel 2704 by three points of engagement with the contact 2700. The three points of engagement shown in
The contact 2700 moves in the wiping direction 200A by a lateral distance 2800 when the contact 2700 mates with the conductive element 108 and slides along the sliding surface 2734. The lateral distance 2800 represents the distance between the initial position 118 and the mated position 202. For example, the lateral distance 2800 may be the distance that the longitudinal axis 2722 moves when the contact 2700 wipes across the conductive element 108. The guidance shoulder 2740 may engage the angled wall 2738 as the contact 2700 moves in the wiping direction 200A in order to keep the longitudinal axis 2722 of the contact 2700 approximately perpendicular to the upper surface 2732 of the connector 104. For example, the guidance shoulder 2740 may slide along the angled wall 2738 and keep the longitudinal axis 2722 parallel to the orientation of the longitudinal axis 2722 when the longitudinal axis 2722 was located at the initial position 118.
The contact 2700 also inwardly moves into the channel 2704 when the contact 2700 mates with the conductive element 108 and slides along the sliding surface 2734. The contact 2700 moves into the channel 2704 by a vertical distance 2802. The vertical distance 2802 may be measured in a direction that is perpendicular to the wiping direction 200A. The vertical distance 2802 is the distance that the mating end 2720 moves toward the front end 2716 in the illustrated embodiment. The vertical distance 2802 also may represent the distance that the resilient member 2730 is compressed between the attachment area 2724 of the contact 2700 and the interconnecting wall 2714.
In the illustrated embodiment, the vertical distance 2802 that the contact 2700 moves into the channel 2704 is greater than the lateral distance 2800 that the contact 2700 moves in the wiping direction 200A. The angle 2728 between the sliding surface 2734 and the longitudinal axis 2722 of the contact 2700 may be sufficiently small that the contact 2700 moves farther into the channel 2704 than the contact 2700 moves in the wiping direction 200A. For example, the lateral distance 2800 that the contact 2700 moves across the conductive element 108 may be relatively small in proportion to the vertical distance 2802 that the contact 2700 recedes into the channel 2704 and/or the resilient member 2730 is compressed.
The contact 2900 may be elongated along a longitudinal axis 2908 between a mating end 2910 and an interface end 2912. Alternatively, the contact 2900 may be a non-elongated contact. A resilient member 2914 is disposed between the conductive interface 2906 of the connector 2902 and the interface end 2912 of the contact 2900. The resilient member 2914 may be a conductive spring or a conductive polymer. The resilient member 2914 may electrically couple the contact 2900 with the conductive interface 2906.
The connector 2902 includes an angled slot 2916 that extends into the channel 2904. The contact 2900 includes a lateral pin 2918 that protrudes from the contact 2900 and is received in the slot 2916. The pin 2918 may be a conductive body that is electrically coupled with the housing 2928. For example, data signals and/or power may be conveyed between the contact 2900 and the housing 2928 by way of the interface between the pin 2918 and the housing 2928 in the angled slot 2916. While the pin 2918 is described in terms of an elongated pin, alternatively the pin 2918 may be a bearing or other mechanism that reduces friction between the contact 2900 and the connector 2902 when the pin 2918 moves in the slot 2916. In the illustrated embodiment, the pin 2918 has an oblong cross-sectional area. For example, as shown in
Prior to mating the contact 2900 with the conductive element 108 of the connector 104, the longitudinal axis 2908 is in the initial position 118. As the connector 2902 moves toward the connector 104 and/or the connector 104 moves toward the connector 2902, the mating end 2910 of the contact 2900 engages the conductive element 108. Continued movement of the connector 2902 toward the connector 104 and/or the connector 104 toward the connector 2902 causes the contact 2900 to be inwardly moved into the channel 2904.
Inward movement of the contact 2900 causes the pin 2918 to move within the slot 2916. The pin 2918 is an angled interface to the contact 2900 that translates movement of the connector 2902 toward the connector 104 (and/or movement of the connector 104 toward the connector 2902) into lateral movement of the contact 2900. The pin 2918 moves with the contact 2900 and within the slot 2916 to guide the contact 2900 in corresponding directions. For example, the pin 2918 may move in a first direction 2922 in the slot 2916 when the contact 2900 is forced inward by engagement with the conductive element 108. The contact 2900 is guided by movement of the pin 2918 in the slot 2916 such that the longitudinal axis 2908 of the contact 2900 moves from the initial position 118 toward the mated position 202. As the contact 2900 moves inward, the resilient member 2914 is compressed between the conductive interface 2906 and the interface end 2912 of the contact 2900. The oblong shape of the pin 2918 may prevent the pin 2918 from rotating within the slot 2916. For example, the oblong shape of the cross-sectional area of the pin 2918 may prevent the contact 2900 from rotating about the pin 2918. Otherwise, rotation of the contact 2900 about the pin 2918 may cause the longitudinal axis 2908 of the contact 2900 to become obliquely oriented with respect to the longitudinal axis 2908 in the initial position 118 as the contact 2900 moves in the channel 2904.
The pin 2918 may move in an opposite second direction 2924 in the slot 2916 when the contact 2900 is moved away from the conductive element 108 to guide the contact 2900 in the channel 2904 from the mated position 202 to the initial position 118. For example, the compressed resilient member 2914 may impart a force on the contact 2900 that moves the contact 2900 in the channel 2904 such that the pin 2918 moves in the second direction 2924 within the slot 2916. The movement of the pin 2918 in the slot 2916 translates movement of the connector 2902 away from the connector 104 and/or movement of the connector 104 away from the connector 2902 into lateral movement of the contact 2900 from the mated position 202 to the initial position 118.
Several rotating arms 1214 join the mating array 1210 to the body 1208. In the illustrated embodiment, the arms 1214 are four elongated arms located at the corners of the mating array 1210. Alternatively, a different number of arms 1214 may be provided and/or the arms 1214 may be joined elsewhere to the mating array 1210. The rotating arms 1214 separate the mating array 1210 from the body 1208 such that a gap 1216 exists between the body 1208 and the mating array 1210. The arms 1214 rotate along respective arcs 1218 to move the mating array 1210 closer to or farther from the body 1208. For example, the arms 1214 may rotate toward the body 1208 to move the mating array 1210 toward the body 1208 and reduce the size of the gap 1216 between the body 1208 and the mating array 1210. Conversely, the arms 1214 may rotate away from the body 1208 to move the mating array 1210 away from the body 1208 and increase the size of the gap 1216. In one embodiment, the arms 1214 include or are coupled with resilient bodies (not shown), such as springs, that are compressed when the arms 1214 rotate toward the body 1208. For example, the arms 1214 may include or be joined with torsion springs that are loaded when a compressive force 1220 is applied to the mating array 1210 in a direction toward the body 1208. The compressive force 1220 causes the mating array 1210 to move toward the body 1208 and the arms 1214 to rotate toward the body 1208. The loaded torsion springs apply a resistive force on the arms 1214 in an opposite direction of the compressive force 1220. The resistive force rotates the arms 1214 away from the body 1208 and moves the mating array 1210 away from the body 1208 when the compressive force 1220 is removed or sufficiently reduced. For example, the resilient bodies of the arms 1214 may keep the mating array 1210 separated from the body 1208 when the first and second connectors 1202, 1204 are not mated with each other.
The mating array 1210 includes several resilient members 1308 presented on the opposite side 1310 of the substrate 1212. For example, the resilient members 1308 may be mounted to the side 1310 of the substrate 1212 that is opposite of the mating side 1302. In the illustrated embodiment, one resilient member 1308 is provided for each contact 1206 of the mating array 1210. Alternatively, one resilient member 1308 may be provided for several contacts 1206 or more than one resilient member 1308 may be provided for each contact 1206. In another embodiment, a single resilient member 1308, such as a sheet of resilient material, may be disposed on the opposite side 1310 of the substrate 1212.
The resilient members 1308 are bodies that are capable of being compressed between the mating array 1210 and the body 1208 when the connectors 1202, 1204 mate with each other and the mating array 1210 is moved toward the body 1208 of the first connector 1202. For example, in the illustrated embodiment, the resilient members 1308 include or are formed from a polymer that can be compressed. Alternatively, the resilient members 1308 may be springs that are compressed between the mating array 1210 and the body 1208. In another example, the resilient members 1308 may be spring fingers that are compressed between the mating array 1210 and the body 1208. Other alternative forms and compositions of the resilient members 1308 may be used.
As the mating array 1210 moves toward the body 1208, the arms 1214 rotate toward the body 1208. The rotation of the arms 1214 toward the body 1208 causes the mating array 1210 and the contacts 1206 of the first connector 1202 to move in a wiping direction 1702 relative to the contacts 1304 of the second connector 1204. As shown in
As shown in
As described above, the arms 1214 may include or be coupled with resilient bodies such as springs that cause the arms 1214 to rotate away from the body 1208 and the mating array 1210 to move away from the body 1208 when the first and second connectors 1202, 1204 move away from each other. For example, the mating array 1210 may return to the position shown in
The first connector 2102 includes rotating arms 2114 that join the mating array 2110 to the body 2108. In the illustrated embodiment, the rotating arms 2114 are two hinge elements that are joined to opposite sides of the mating array 2110. Alternatively, a different number of rotating arms 2114 may be provided and/or the rotating arms 2114 may be joined to the mating array 2110 in different locations. The rotating arms 2114 separate the mating array 2110 from the body 2108. The rotating arms 2114 rotate along respective arcs 2118 to move the mating array 2110 closer to or farther from the body 2108, similar to as described above in connection with the arms 1214 of the first connector 1202 shown in
The contacts 2106 are presented on a mating side 2202 of the mating array 2110. The contacts 2106 engage pairing contacts 2204 on a surface 2206 of the second connector 2104. The contacts 2204 of the second connector 2104 may be similar to the contacts 1304 (shown in
In the illustrated embodiment, resilient bodies 2214 are disposed within the rotating arms 2114. The resilient bodies 2214 shown in
As shown in
Once the contacts 2106 of the first connector 2102 engage the contacts 2204 of the second connector 2104, further movement of the first connector 2102 relative to the second connector 2104 in the mating direction 2402 causes the mating array 2110 to be pushed toward the body 2108 of the first connector 2102. As the mating array 2110 moves toward the body 2108, the rotating arms 2114 rotate toward the body 2108. The rotation of the rotating arms 2114 causes the mating array 2110 and the contacts 2106 of the first connector 2102 to move in a wiping direction 2602 relative to the contacts 2204 of the second connector 2104. The mating direction 2402 may be approximately perpendicular to the lateral wiping direction 2602. The lateral movement of the contacts 2106 across the contacts 2204 may remove one or more layers of surface contamination on the contacts 2204 such that the contacts 2106, 2204 are electrically coupled with one another. The contacts 2106 may wipe across the contacts 2204 such that the electrical connection between the contacts 2106 and the contacts 2204 is improved over contacts 2106 that do not wipe across the contacts 2204.
The resilient bodies 2214 are compressed between the rotating arms 2114 and the body 2108 when the connectors 2102, 2104 are mated. The compression of the resilient bodies 2214 causes the resilient bodies 2214 to exert forces on the mating array. When the connectors 2102, 2104 are moved away from each other, the forces exerted by the resilient bodies 2214 may cause the mating array 2110 to move away from the body 2108 and return to the position shown in
