The subject matter herein relates generally to communication systems.
Communication systems use electrical connectors to transmit data between components of the communication system. For example, electrical connectors may be held in a rack, chassis, cabinet or other system component. Mating connectors are mated to the electrical connectors. For example, the mating connectors may be mounted to a card assembly, such as a daughtercard or server card, which is plugged into the chassis. Proper mating of the mating connector with the electrical connector is necessary for proper operation of the communication system. For example, misalignment of the connectors may lead to damage to the contacts of the connectors. Additionally, partial mating of the connectors may lead to reduction in signal integrity due to partial mating of contacts and/or improper shielding of the signal contacts. In some systems, the server card may be mated with the assistance of a lever or other mechanical assist device to plug the server card into the chassis. Such mechanical loading of the server card may lead to damage to the electrical connector. Additionally, mounting of the electrical connectors within the rack may require special tools or mounting hardware, which adds cost and complexity to the system.

The connector assembly 102 includes a connector holder 200 used to hold the cable connector 130. The connector holder 200 is configured to be coupled to the cartridge 110 (
The connector holder 200 includes a frame 202 defining a connector chamber 204. The cable connector 130 is received in the connector chamber 204. The frame 202 supports the cable connector 130 in the connector chamber 204. The frame 202 extends between a front 206 and a rear 208 of the connector holder 200. The mating ends of the cable connector 130 is provided at or forward of the front 206 of the connector holder 200 for mating with the mating electrical connector 106. The cable 150 extends from the rear 208 of the connector holder 200. The mating guide 120 extends forward from the front 206, such as above the cable connector 130. Other locations are possible in alternative embodiments, such as the bottom for one or both sides of the frame 202.
In an exemplary embodiment, the frame 202 includes an upper frame member 210, a lower frame member 212, a first side frame member 214, a second side frame member 216, and a rear frame member 218. The connector chamber 204 is defined between the upper frame member 210 and the lower frame member 212. The connector chamber 204 is defined between the first and second side frame members 214, 216. The upper frame member 210, the lower frame member 212, the first side frame member 214, and the second side frame member 216 forming a brick 220 used to hold the cable connector 130. The brick 220 is a rectangular structure that surrounds the connector chamber 204.

The second side frame member 216 may be coupled to the upper and lower frame members 210, 212 after the cable connector 130 is loaded into the connector chamber 204 through the second side. However, in alternative embodiments, the second side frame member 216 may be integral with the upper frame member 210 and/or the lower frame member 212, such as being diecast with and/or stamped and formed from a common metal material.
In an exemplary embodiment, the first side frame member 214 is integral with the upper and lower frame members 210, 212.

However, in alternative embodiments, the rear frame member 218 may be separate from the upper and lower frame members 210, 212, which may allow the upper and lower frame members 210, 212 to move relative to the rear frame member 218, such as to allow the cable connector 130 to move relative to the rear frame member 218 (for example, along the mating axis in the Z-direction).
In an exemplary embodiment, mounting features 224 extend from the brick 220 to mount the brick 220 to the cartridge 110. In the illustrated embodiment, the mounting features 224 are threaded fasteners coupled to the upper frame member 210 and the lower frame member 212.

In an exemplary embodiment, the connector assembly 102 includes a biasing assembly 300 operably coupled between the cable connector 130 and the connector holder 200. The biasing assembly 300 allows the cable connector 130 to move relative to the connector holder 200. For example, the biasing assembly 300 allows the cable connector 130 to move along the mating axis 126 (Z-direction), such as to accommodate overtravel of the mating connector assembly 104 during mating. In an exemplary embodiment, the biasing assembly 300 includes one or more biasing members 302. In the illustrated embodiment, the biasing member 302 is a compression spring, such as a coil spring. However, other types of biasing members may be used in alternative embodiments. The biasing member 302 may include other types of springs, such as a leaf spring, a Belleville spring, a wave spring, a torsion spring. The biasing member 302 may include another type of compression element, such as a foam compression member, a rubber compression member, and the like.
The biasing member 302 is coupled to the rear frame member 218. For example, the rear frame member 218 may include a mounting post 226 that receives the biasing member 302. Other types of mounting features may be used in alternative embodiments. In the illustrated embodiment, the mounting posts 226 are provided along the upper and lower arms of the rear frame member 218 located on opposite sides of a cable exit 228 through the rear frame member 218.
In various embodiments, the biasing members 302 may directly engage the cable connector 130 to forward bias the cable connector 130 relative to the rear frame member 218. However, in alternative embodiments, the biasing assembly 300 may include one or more sliders 310 between the biasing member 302 and the cable connector 130. The sliders 310 are movable relative to the brick 220. The sliders 310 hold the cable connector 130 and allow the cable connector 130 to move relative to the brick 220. The biasing members 302 forward bias the sliders 310 and thus the cable connector 130 relative to the rear frame member 218 and hold the cable connector 130 in a forward position for mating with the mating electrical connector 106. In the illustrated embodiment, a pair of sliders 310 and a pair of the biasing members 302 are provided. The cable connector 130 is held between the sliders 310.
In an exemplary embodiment, the sliders 310 are coupled to the upper frame member 210 and the lower frame member 212. For example, the upper frame member 210 includes a rail 230 and the lower frame member 212 includes a rail 232. Each slider 310 includes a track 312 that receives the corresponding rail 230, 232. The rails 230, 232 guide movement of the sliders 310 relative to the upper and lower frame members 210, 212. For example, the rails 230, 232 limit movement of the sliders 310 to movement parallel to the mating axis (Z-direction).
In an exemplary embodiment, each slider 310 includes a slot 314 that receives a mounting lug 136 that extend from the connector housing 132. In the illustrated embodiment, the slot 314 extends crosswise across the slider 310 between the opposite sides of the slider 310 (X-direction). In an exemplary embodiment, the slider 310 is oversized relative to the connector housing 132 allowing the mounting lugs 136 to move side-to-side within the slots 314 to allow a limited amount of lateral floating movement of the cable connector 130 relative to the slider 310. As such, the connector housing 132 is movable in the X-direction relative to the sliders 310 and the connector holder 200. The amount of lateral movement may be limited to a confined amount by the first and second side frame members 214, 216 (for example, 1.0 mm).
In an exemplary embodiment, the sliders 310 may have a spacing therebetween to receive the cable connector 130. The spacing may be slightly taller than the height of the connector housing 132 to allow a limited amount of floating movement of the cable connector 130 between the sliders 310. As such, the connector housing 132 is movable in the Y-direction relative to the sliders 310 and the connector holder 200. The spacing between the sliders 310 limits the amount of floating movement to a confined amount (for example, 1.0 mm).
During mating, the mating guide 120 interfaces with the mating guide 122 to generally align the mating electrical connector 106 with the cable connector 130. During final mating, the walls of the connector housing 132 interface with the mating electrical connector 106 as the mating electrical connector 106 is plugged into the cavity 134. In an exemplary embodiment, the cable connector 130 is able to move relative to the connector holder 200 in a floating direction to accommodate misalignment of the mating electrical connector 106 and the cable connector 130. For example, the connector housing 132 of the cable connector 130 may move in the vertical direction (Y-direction) between the upper and lower sliders 310 to align the cable connector 130 with the mating electrical connector 106.
In an exemplary embodiment, the connector holder 200 may be movable relative to the cartridge 110 to accommodate misalignment between the cable connector 130 and the mating electrical connector 106. For example, the mounting features 224 (see
During mating, the mating connector assembly 104 is plugged into the rack or chassis in a mating direction along the mating axis 126. The mating ends of the mating electrical connector 106 is plugged into the cavity 134 of the connector housing 132 to electrically connect the signal contacts and the shields with the mating electrical connector 106. Once fully mated, further loading of the mating connector assembly 104 in the mating direction causes compression of the biasing assembly 300. For example, the biasing members 302 are compressed allowing the sliders 310 and the cable connector 130 to move in a rearward compression direction to accommodate the overloading of the mating connector assembly 104. The sliders 310 and the cable connector 130 are moved in the rearward compression direction toward the rear frame member 218. The sliders 310 slide relative to the brick 220. For example, the sliders 310 slide rearward relative to the upper frame member 210 and the lower frame member 212. The mounting lugs 136 transfer forces and movement between the cable connector 130 and the sliders 310.
The biasing members 302 are compressible in the rearward compression direction to allow the cable connector 130 to move to a rearward position, which prevents damage to the cable connector 130 and the mating electrical connector 106 during the mating process. In an exemplary embodiment, the biasing members 302 may be preloaded to a predetermined spring force. As such, the biasing members 302 are not compressed until the predetermined spring force is exceeded. The preload spring force may be greater than the mating force to fully mate the mating electrical connector 106 with the cable connector 130. For example, the mating force may be defined by the force required to mate the signal contacts and the shields. In various embodiments, the mating force may be less than 20 pounds. The preload spring force may be set at 20 pounds to allow mating of the signal contacts and the shields without rearward movement of the cable connector 130. The biasing members 302 compress only when the preload force is exceeded.
In an exemplary embodiment, the cable connector 130 is able to move relative to the connector holder 200 in a floating direction to accommodate misalignment of the mating electrical connector 106 and the cable connector 130. For example, the connector housing 132 of the cable connector 130 may move in the horizontal direction (X-direction) relative to the slider 310 to align the cable connector 130 with the mating electrical connector 106. The mounting lugs 136 are movable side-to-side within the slot 314 to accommodate the floating movement in the horizontal direction. The mounting lugs 136 may move side to side until the mounting lugs 136 and/or the connector housing 132 engage the first and second sides frame members 214, 216.
In an exemplary embodiment, the connector holder 200 may be movable relative to the cartridge 110 to accommodate misalignment between the cable connector 130 and the mating electrical connector 106. For example, the mounting features 224 holding the connector holder 200 to the panels 112 of the cartridge 110 may be movable relative to the panels 112. For example, the heads of the mounting features 224 may have a slight spacing between the interior of the heads of the mounting features 224 and the exterior surfaces of the panels 112 to allow a limited amount of side-to-side, floating movement in the horizontal direction.
The connector assembly 102 includes the connector holder 200 used to hold the cable connector 130. The frame 202 of the connector holder 200 includes the upper frame member 210, the lower frame member 212, the first side frame member 214, the second side frame member 216, and the rear frame member 218. In the illustrated embodiment, the first side frame member 214 is separate and discrete from the upper and lower frame members 210, 212 and coupled thereto similar to the second side frame member 216 using fasteners 222 to form the brick 220.
The biasing assembly 300 is operably coupled between the cable connector 130 and the connector holder 200. The biasing assembly 300 allows the cable connector 130 to move relative to the connector holder 200. For example, the biasing assembly 300 allows the cable connector 130 to move along the mating axis 126 (Z-direction), such as to accommodate overtravel of the mating connector assembly 104 during mating. The biasing members 302 are coupled to the rear frame member 218 and the sliders 310. The sliders 310 are movable relative to the brick 220 and allow the cable connector 130 to move relative to the brick 220. The biasing members 302 forward bias the sliders 310 and thus the cable connector 130 relative to the rear frame member 218 and hold the cable connector 130 in a forward position for mating with the mating electrical connector 106. The mounting lugs 136 are received in the slots 314 to position the cable connector 130 relative to the sliders 310. The mounting lugs 136 are able to move side-to-side (X-direction) within the slots 314 to allow a limited amount of lateral floating movement of the cable connector 130 relative to the slider 310. The spacing between the sliders 310 may be slightly taller than the height of the connector housing 132 to allow a limited amount of vertical floating movement (Y-direction) of the cable connector 130 between the sliders 310.
The biasing assembly 300 is operably coupled between the cable connector 130 and the connector holder 200. The biasing assembly 300 allows the cable connector 130 to move relative to the connector holder 200. For example, the biasing assembly 300 allows the cable connector 130 to move along the mating axis 126 (Z-direction), such as to accommodate overtravel of the mating connector assembly 104 during mating. The biasing members 302 are coupled to the rear frame member 218 and the sliders 310. The sliders 310 are movable relative to the frame members and allow the cable connector 130 to move relative to the frame members. The biasing members 302 forward bias the sliders 310 and thus the cable connector 130 relative to the rear frame member 218 and hold the cable connector 130 in a forward position for mating with the mating electrical connector 106. The mounting lugs 136 are received in the slots 314 to position the cable connector 130 relative to the sliders 310. The mounting lugs 136 are able to move side-to-side (X-direction) within the slots 314 to allow a limited amount of lateral floating movement of the cable connector 130 relative to the slider 310. The spacing between the sliders 310 may be slightly taller than the height of the connector housing 132 to allow a limited amount of vertical floating movement (Y-direction) of the cable connector 130 between the sliders 310.
The connector assembly 102 includes the connector holder 200 used to hold the cable connector 130. The connector holder 200 is configured to be coupled to the cartridge 110 (
In an exemplary embodiment, the frame 202 includes the upper frame member 210, the lower frame member 212, the first side frame member 214, the second side frame member 216, and the rear frame member 218 (
In an exemplary embodiment, the upper and lower frame members 210, 212 include slots 240 that receive the mounting lugs 136 extending from the connector housing 132. The slots 240 position the connector housing 132 within the connector chamber 204. In an exemplary embodiment, the slots 240 are oversized relative to the mounting lugs 136 to allow a limited amount of floating movement of the cable connector 130 within the connector chamber 204. For example, the mounting lugs 136 may move laterally (X-direction). The mounting lugs 136 may move in the mating direction (Z-direction). In an exemplary embodiment, the upper and lower frame members 210, 212 may have a spacing therebetween to receive the cable connector 130. The spacing may be slightly taller than the height of the connector housing 132 to allow a limited amount of floating movement of the cable connector 130 between the upper and lower frame members 210, 212. As such, the connector housing 132 is movable in the Y-direction relative to the upper and lower frame members 210, 212. The spacing between the upper and lower frame members 210, 212 limits the amount of floating movement to a confined amount (for example, 1.0 mm).
In an exemplary embodiment, the first and second side frame members 214, 216 include channels 242 that receive sliders 330 of the biasing assembly 300. The channels 242 extend between front and rear ends of the side frame members 214, 216. In an exemplary embodiment, the first and second side frame members 214, 216 are configured to slide along the sliders 330. The panel mounts 320 are provided at the front ends of the sliders 330. The rear ends of the sliders 330 are configured to be coupled to the rear frame member 218. For example, the rear ends of the sliders 330 may be threadably coupled to the front face of the rear frame member 218. The panel mounts 320 are fixed relative to the rear frame member 218. The first and second side frame members 214, 216 are movable between the panel mounts 320 and the rear frame member 218.
In an exemplary embodiment, the connector assembly 102 includes the biasing assembly 300 (
In an exemplary embodiment, each slider 330 includes a head 332 and a shaft 334 extending from the head 332. A lip 336 may extend around the shaft 334 proximate to the head 332. For example, the lip 336 may be located immediately rearward of the head 332. The lip 336 has a larger diameter than the shaft 334. The shaft 334 and the lip 336 both have smaller diameters than the head 332. The shaft 334 is received in the corresponding channel 242 of the side frame member 214, 216. Optionally, the channel 242 may be oversized relative to the shaft 334 to allow a limited amount of floating movement of the side frame member 214, 216 relative to the shaft 334. The floating movement allows the cable connector 130 to move relative to the slider 330 and thus move relative to the cartridge 110 to align the cable connector 130 with the mating electrical connector 106 during mating.
When assembled, the cable connector 130 is received in the connector chamber 204 and held by the brick 220. The sliders 330 pass through the side frame members 214, 216 and are coupled to the rear frame member 218. The panel mount 320 at the front end of each slider 330 is located forward of the corresponding side frame member 214, 216. The biasing members 302 forward bias the brick 220, and thus the cable connector 130, relative to the rear frame member 218 to the forward position (
During assembly, the connector assembly 102 is coupled to the front panel 114 from behind the front panel 114. The brick 220 is held in the rearward position to expose the panel mount 320 forward of the side frame members 214, 216. The panel mounts 320 are aligned with the mounting openings 160 (
During mating with the mating connector assembly 104, loading of the mating connector assembly 104 in the mating direction may cause compression of the biasing assembly 300. For example, the biasing members 302 may be compressed when the preload spring force is overcome. The brick 220 and the cable connector 130 are allowed to move rearward along the sliders 330 to compress the biasing members 302 in the rearward compression direction to accommodate the overloading of the mating connector assembly 104. The brick 220 and the cable connector 130 are moved in the rearward direction toward the rear frame member 218. The sliders 330 hold the rear frame member 218 in a fixed location relative to the front panel 114.
The connector assembly 102 includes the connector holder 200 used to hold the cable connector 130. The connector holder 200 is configured to be coupled to the cartridge 110 to position the cable connector 130 relative to the cartridge 110.

The connector holder 200 includes the frame 202 defining the connector chamber 204. The cable connector 130 is received in the connector chamber 204. The frame 202 supports the cable connector 130 in the connector chamber 204. The mating end of the cable connector 130 is provided at or forward of the front 206 of the connector holder 200 for mating with the mating electrical connector 106. The cable 150 extends from the rear 208 of the connector holder 200. The mating guide 120 extends forward from the front 206, such as above the cable connector 130. Other locations are possible in alternative embodiments, such as the bottom for one or both sides of the frame 202.
In an exemplary embodiment, the frame 202 includes the upper frame member 210, the lower frame member 212, the first side frame member 214, the second side frame member 216, and the rear frame member 218. The connector chamber 204 is defined between the upper frame member 210 and the lower frame member 212. The connector chamber 204 is defined between the first and second side frame members 214, 216. The upper frame member 210, the lower frame member 212, the first side frame member 214, and the second side frame member 216 form the brick 220 used to hold the cable connector 130. The brick 220 is configured to be coupled to the cartridge 110 to hold the cable connector 130 relative to the cartridge 110. The rear frame member 218 may be coupled to the brick 220. The rear frame member 218 closes off the connector chamber 204 from behind.
In an exemplary embodiment, the second side frame member 216 is separate and discrete from the upper and lower frame members 210, 212. The second side frame member 216 is coupled to the upper and lower frame members 210, 212 using fasteners 222. The second side frame member 216 may be coupled to the upper and lower frame members 210, 212 after the cable connector 130 is loaded into the connector chamber 204 through the second side. However, in alternative embodiments, the second side frame member 216 may be integral with the upper frame member 210 and/or the lower frame member 212, such as being diecast with and/or stamped and formed from a common metal material.
In an exemplary embodiment, the first side frame member 214 is integral with the upper and lower frame members 210, 212. For example, the first side frame member 214 may be diecast with the upper and lower frame members 210, 212 into a U-shaped structure having a closed first side and open second side configured to receive the cable connector 130 into the connector chamber 204 through the open second side. However, in alternative embodiments, the first side frame member 214 may be separate and discrete from the upper and lower frame members 210, 212 and coupled thereto using fasteners.
In an exemplary embodiment, the rear frame member 218 is coupled to the upper frame member 210 and/or the lower frame member 212 using fasteners. The rear frame member 218 may be fixed in place relative to the upper and lower frame members 210, 212 using the fasteners. However, in alternative embodiments, the rear frame member 218 may be separate from the upper and lower frame members 210, 212, which may allow the upper and lower frame members 210, 212 to move relative to the rear frame member 218, such as to allow the cable connector 130 to move relative to the rear frame member 218 (for example, along the mating axis in the Z-direction).
In an exemplary embodiment, mounting features 224 extend from the brick 220 to mount the brick 220 to the cartridge 110. In the illustrated embodiment, the mounting features 224 are mounting tabs 225 extending from the rear frame member 218. The mounting features 224 may additionally or alternatively extend from the upper frame member 210 and the lower frame member 212. The mounting tabs 225 may be provided proximate to the first and second sides, such as to interface with the cartridge 110. The mounting tabs 225 are rectangular shaped; however, the mounting tabs 225 may have other shapes in alternative embodiments. Other types of mounting features may be used in alternative embodiments. The mounting features 224 may be located at other locations in alternative embodiments.
In an exemplary embodiment, the connector assembly 102 includes the biasing assembly 300 operably coupled between the cable connector 130 and the connector holder 200. The biasing assembly 300 allows the cable connector 130 to move relative to the connector holder 200. For example, the biasing assembly 300 allows the cable connector 130 to move along the mating axis 126 (Z-direction), such as to accommodate overtravel of the mating connector assembly 104 during mating. In an exemplary embodiment, the biasing assembly 300 includes the biasing members 302.
The biasing assembly 300 includes the sliders 310 between the biasing member 302 and the cable connector 130. The sliders 310 are movable relative to the brick 220. The sliders 310 hold the cable connector 130 and allow the cable connector 130 to move relative to the brick 220. The biasing members 302 forward bias the sliders 310 and thus the cable connector 130 relative to the rear frame member 218 and hold the cable connector 130 in a forward position for mating with the mating electrical connector 106.
In an exemplary embodiment, the cable connector 130 is able to move relative to the connector holder 200 in a floating direction to accommodate misalignment of the mating electrical connector 106 and the cable connector 130. For example, the connector housing 132 of the cable connector 130 may move in the horizontal direction (X-direction) relative to the slider 310 to align the cable connector 130 with the mating electrical connector 106. The mounting lugs 136 are movable side-to-side within the slot 314 to accommodate the floating movement in the horizontal direction. The mounting lugs 136 may move side to side until the mounting lugs 136 and/or the connector housing 132 engage the first and second sides frame members 214, 216.
In an exemplary embodiment, the connector holder 200 may be movable relative to the cartridge 110 to accommodate misalignment between the cable connector 130 and the mating electrical connector 106. For example, the connector holder 200 may be movable relative to the cartridge 110 to accommodate misalignment between the cable connector 130 and the mating electrical connector 106. The mounting tabs 225 holding the connector holder 200 to the panels 112 of the cartridge 110 may be slidable or movable within the slots 119. For example, the slots 119 that receive the mounting tabs 225 may be elongated or oversized to allow floating movement of the mounting tabs 225 within the slots 119 to allow a limited amount of vertical and/or horizontal floating movement. During mating, once fully mated, further loading of the mating connector assembly 104 in the mating direction causes compression of the biasing assembly 300. For example, the biasing members 302 are compressed allowing the sliders 310 and the cable connector 130 to move in a rearward compression direction to accommodate the overloading of the mating connector assembly 104. The sliders 310 and the cable connector 130 are moved in the rearward compression direction toward the rear frame member 218. The sliders 310 slide relative to the brick 220. For example, the sliders 310 slide rearward relative to the upper frame member 210 and the lower frame member 212. The mounting lugs 136 transfer forces and movement between the cable connector 130 and the sliders 310.
The biasing members 302 are compressible in the rearward compression direction to allow the cable connector 130 to move to a rearward position, which prevents damage to the cable connector 130 and the mating electrical connector 106 during the mating process. In an exemplary embodiment, the biasing members 302 may be preloaded to a predetermined spring force. As such, the biasing members 302 are not compressed until the predetermined spring force is exceeded. The preload spring force may be greater than the mating force to fully mate the mating electrical connector 106 with the cable connector 130. For example, the mating force may be defined by the force required to mate the signal contacts and the shields. In various embodiments, the mating force may be less than 20 pounds. The preload spring force may be set at 20 pounds to allow mating of the signal contacts and the shields without rearward movement of the cable connector 130. The biasing members 302 compress only when the preload force is exceeded.
The connector assembly 102 includes the connector holder 200 used to hold the cable connector 130. The frame 202 of the connector holder 200 includes the upper frame member 210, the lower frame member 212, the first side frame member 214, the second side frame member 216, and the rear frame member 218. In the illustrated embodiment, the first side frame member 214 is separate and discrete from the upper and lower frame members 210, 212 and coupled thereto similar to the second side frame member 216 using fasteners 222 to form the brick 220. The rear frame member 218 includes the mounting tabs 225 used to position the connector assembly 102 relative to the cartridge 110.
The biasing assembly 300 is operably coupled between the cable connector 130 and the connector holder 200. The biasing assembly 300 allows the cable connector 130 to move relative to the connector holder 200.

The biasing members 302 forward bias the sliders 310 and thus the cable connector 130 relative to the rear frame member 218 and hold the cable connector 130 in a forward position for mating with the mating electrical connector 106. The mounting lugs 136 are received in the slots 314 to position the cable connector 130 relative to the sliders 310. The mounting lugs 136 are able to move side-to-side (X-direction) within the slots 314 to allow a limited amount of lateral floating movement of the cable connector 130 relative to the slider 310. The spacing between the sliders 310 may be slightly taller than the height of the connector housing 132 to allow a limited amount of vertical floating movement (Y-direction) of the cable connector 130 between the sliders 310.
