Description of the Invention
[0023] Fig. 1 is an isometric view of communications channel 10, which includes two SPE cables 12 terminated to SPE plugs 14 connected by SPE coupler 16. Communications channel 10 can be located in cabinets, racks, zone enclosures, and other such infrastructure.
[0024] Fig. 2 is an exploded view of communications channel 10 with SPE plugs 14 removed from SPE coupler 16.
[0025] Fig. 3 is an exploded view of SPE coupler 16, which includes coupler housings 18x and 18 2 , contacts 20i and 20 2 , and shield wrap 22. Fig. 4 is an exploded underside view of SPE coupler 16. Shield wrap 22 is shown in an open position. Coupler housings 181 and 18 2 are identical. Contacts 20i and 20 2 are identical. Contacts 20 are slid into openings 24 of coupler housings 18 until bend 26 on contacts 20 meet with stop face 28 on coupler housings 18. Latch 30 on coupler housing 18 | connects to catch 32 on coupler housing 18 2 . Likewise, latch 30 on coupler housing 18 2 connects to catch 32 on coupler housing 18 Bosses 34 fit inside pockets 36 when coupler housings 18 x and 18 2 are assembled to help align the two housings. [0026] Shield wrap 22 is placed over the top of the assembled coupler housings 18. Louvers 38 on crimped flanges 40 snap into windows 42 on flanges 44 of shield wrap 22 when shield wrap 22 is placed over the assembled coupler housings 18. This action holds shield wrap 22 in a closed position. Shield wrap 22 is designed to help meet performance requirements laid out in IEC and TIA specifications. Wiping tabs 46 on shield wrap 22 fit into open slots 54 on coupler housings 18 to meet IEC dimensional specifications. Wiping tabs 46 on shield wrap 22 of SPE coupler 16 come into contact with SPE plugs 14 to create bonding throughout communications channel 10. Contact 20 x routes the signal from the top wire of SPE plug 14x to the top wire of SPE plug 14 2 to create a continuous connection for an expanded cabling solution. Equally, contact 20 2 routes the signal from the bottom wire of SPE plug 14 2 to the bottom wire of SPE plug 14 2 to create a continuous connection for an expanded cabling solution.
[0027] Fig. 5 is an underside view of SPE coupler 16. Latches 48 and stop edges 50 on the bottom of coupler housings 18 of SPE coupler 16 are designed to lock SPE coupler 16 into any number of fixed modules designed to secure SPE coupler 16 in place after implementation. These modules can be located in cabinets, racks, zoneenclosures, andother such infrastructure. [0028] Fig. 6 is a front view of SPE coupler 16. Grounding tab 52 is designed to interact with any number of fixed modules designed to secure SPE coupler 16 in place after implementation and provide bonding throughout the communications system. SPE coupler 16 is designed to meet the fixed connector dimensional criteria described in IEC 63171-1 which will allow for proper insertion of SPE plugs 14.
[0029] Fig. 7 is a rotated side view of an alternate embodimentof SPEcoupler60. SPE coupler 60 would assemble and function in a manner identical to the previously described SPE coupler 16. SPE coupler 60 includes coupler housings 62, contacts 20 (not shown), and shield wrap 64.
This alternate embodiment shows that coupler housings 62 can be made such that latches 68 and stop edges 70 can be positioned on either the top, the bottom, or both of coupler housings 62 to lock SPE coupler 60 into any number of fixed modules designed to secure SPE coupler 60 in place after implementation. This allows SPE coupler 60 to be installed oriented up or down. These modules can be located in cabinets, racks, zone enclosures, and other such infrastructure. SPE coupler 60 also demonstrates alternative bonding by showing that grounding features 66 on shield wrap 64 can be placed on the side surface of shield wrap 64 to interact with any number of fixed modules designed to secure SPE Coupler 60 in place after implementation and provide bonding throughout the communications system.
