[0026] Figure 2 Is an isometric exploded view of the termination socket assembly 16. The termination socket assembly 16 includes a shielded cable 24, a socket housing assembly 26, and a rear wire cover assembly 28. The shielded cable 24 includes a cable jacket 87, conductors 88, a conductor separator 89, and a braid 94.
[0027] Figure 3 Is a top plan exploded view of the socket housing assembly 26. Figure 4 Is a bottom plan exploded view of the socket housing assembly 26. Figure 5 Is a rear top plan exploded view of the socket housing assembly 26. Figure 6 Is a rear bottom plan exploded view of the socket housing assembly 26. The socket housing assembly 26 includes a front shield wrap 30, a socket housing 32, a PCB assembly 34, a rear sled 36, and a wiring diagram label 38( Figure 5 - Figure 6 ). Figure 3 - Figure 6 Depicts the front shield wrap 30 in its open state prior to final forming. The PCB assembly 34 includes a sled assembly 40, long IDCs 42, IDC supports 44, and a PCB 46. The PCB assembly 34 is constructed and used in the same manner as currently produced unshielded stepped through-hole socket modules.
[0028] The long IDCs 42 of the PCB assembly 34 are press-fit into channels 48 of the rear sled 36 to maintain restraint on the long IDCs 42 during the termination process. The IDC supports 44 of the PCB assembly 34 and the lower support wall 50 of the socket housing 32 provide support for the long IDCs 42 of the PCB assembly 34 during the assembly process. The sled assembly 40 of the PCB assembly 34 slides into an opening 52 in the socket housing 32( Figure 5 - Figure 6)。The D - shaped window latch 54 on the socket housing 32 latches onto the buckle 56 of the rear slider 36 to hold the components together. The wiring diagram label 38 has an adhesive back and is fixed to the rear slider 36. The socket housing 32, the PCB assembly 34, the rear slider 36, and the wiring diagram label 38 in the assembled state slide into the front shield wrapper 30. The flexible latch 58 on the socket housing 32 slides through the opening 60 of the front shield wrapper 30. The side stop 62 of the socket housing 32 passes through the window 64 of the front shield wrapper 30 and helps keep all components from separating before the final shaping of the front shield wrapper 30.
[0029] Figure 7 is a front top view of the socket housing assembly 26 with the front shield wrapper 30 in its closed state before final assembly. Figure 8 is a front bottom view of the socket housing assembly 26 with the front shield wrapper 30 in its open state. Figure 9 is a rear top view of the socket housing assembly 26 with the front shield wrapper 30 in its open state. Figure 10 is a rear bottom view of the socket housing assembly 26 with the front shield wrapper 30 in its open state. For the front shield wrapper 30, as the flange 70 is brought to the final position, the rear protrusion 66 passes through the hole 68. Then, the rear protrusion 66 is formed over the edge 69 of the hole 68 to fix the front shield wrapper 30 in the locked position. The front protrusion 72 is formed over the biasing geometry 74 on the flange 70 of the front shield wrapper 30 for providing additional fixation and shielding continuity.
[0030] Figure 11 is a front top view of the socket housing assembly 26 with the front shield wrapper 30 in its closed state. Figure 12 is a front bottom view of the socket housing assembly 26 with the front shield wrapper 30 in its closed state. Figure 13 is a rear top view of the socket housing assembly 26 with the front shield wrapper 30 in its closed state. Figure 14 is a rear bottom view of the socket housing assembly 26 with the front shield wrapper 30 in its closed state.
[0031] Figure 15 is an exploded front top view of the rear wire cover assembly 28. Figure 16 is an exploded rear bottom view of the rear wire cover assembly 28. The rear wire cover assembly 28 includes a wire cover 76 and a wire cover shield wrapper 78. The wire cover 76 is placed in the wire cover shield wrapper 78. The return flange 80 on the wire cover shield wrapper 78 latches onto the flat edge 82 of the wire cover 76 to hold the components together.
[0032] Figure 17Is a front top exploded view of the rear wire cover assembly 28. The rear wire cover assembly 28 is symmetrically designed to allow the cable opening 90 to point left or right after final assembly.
[0033] Figure 18 Is a cross-sectional view of the communication system 10 taken along the centerlines of the conductors 88 of the un-mated termination socket assembly fixed to the shielded patch panel 12 4 and the conductor 88 7 . The conductors 88 on the shielded cable 24 are pressed into the slots 86 ( Figure 7 - Figure 14 ) in the rear slider 36 and terminated to the long IDC 42 of the socket housing assembly 26. The cutting edge 108 on the rear slider 36 provides a flat surface for the stamping tool to trim the conductors 88 flush. The cable opening 90 on the rear wire cover assembly 28 allows the rear wire cover assembly 28 to be placed onto the socket housing assembly 26 after the shielded cable 24 has been terminated to the long IDC 42 of the socket housing assembly 26. Then, the rear wire cover assembly 28 is placed over the rear end of the socket housing assembly 26. If the ends of the conductors 88 are cut too long after termination or not cut with the stamping tool; the rounded surface 109 on the wire cover 76 of the rear wire cover assembly 28 assists in pushing the overlong conductors or insulation length into the overflow channel 110 on the rear slider 36 of the socket housing assembly 26.
[0034] The ground prong 92 on the wire cover shield wrapper 78 of the rear wire cover assembly 28 is coupled to the braid 94 of the shielded cable 24. The wiping tab 96 ( Figure 3 - Figure 14 ) on the front shield wrapper 30 of the socket housing assembly 26 is connected to the inner wall 98 ( Figure 15 - Figure 17 ) on the wire cover shield wrapper 78 of the rear wire cover assembly 28 to create a fully coupled assembly. The capture slot 100 ( Figure 15 - Figure 17 ) on the wire cover 76 of the rear wire cover assembly 28 passes over the rounded bump 102 ( Figure 7 - Figure 14 ) on the rear slider 36 of the socket housing assembly 26 and secures the rear wire cover assembly 28 to complete the termination socket assembly 16. The separator wall 84 on the wire cover 76 of the rear wire cover assembly 28 slides into the slot 86 of the rear slider 36 of the socket housing assembly 26 and assists in securing the conductors 88 to the shielded cable 24.
[0035] Figure 19 Is a front top view of the termination socket assembly 16. Figure 20 Is a rear top view of the termination socket assembly 16. When the shielded plug assembly 22 and the termination socket assembly 16 are in the mated state, the inner wiping tab 104 provides a connection between the plug shield 23 ( Figure 1 ) on the shielded plug assembly 22. The ground protrusion 106 is designed to couple the termination socket assembly 16 to the shielded patch panel 12 when assembling the components.
