Abstract
Abstract A cross-connect connector for telecommunication systems reduces the required time to install and effect cross-connections if the wire connections are made by hand and changes are made between circuits by unplugging a modular plug and pluggng it in at a different position. The connector of the present invention has a terminal block accepting a plurality of plugs connected each to a pair of wires and the plugs fit onto the terminal block or can be stacked on each other for half tapping, testing or transferring.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
273 words
An electrical connector for connection of pairs of wires to other pairs of wires, said connector comprising: a terminal block, said terminal block comprising a base having means for supporting a plurality of wires transversely thereof, a cover adapted to fit on the base, said cover having a plurality of terminal contacts for making connection to wries supported by the base and for enclosing the ends of the wires in the base, said cover having apertures affording access to said contacts, and said cover having location means about said apertures for polarizing pairs of said apertures; and a plurality of plugs for making contact with said contacts in said terminal block, said plugs comprising an insulative body, said body having opposite ends and a hinged cap supported on one end, a thin metal splicing contact supported in said body with opposite end portions, one end portion of said contact being a tuning fork contact portion adapted to make electrical connection with said terminal contacts and the other end portion being an insulation displacing contact portion adapted to make electrical connection to a jumper wire, said cap having means for facilitating connection between a said jumper wire and said other end portion of said splicing contact, having an aperture therein affording access to said insulation displacing contact portion, and having location means mounted thereon to afford proper location of a second plug on said cap, the other end of said body having means for mating with said location means of said cover for positioning said one end portion of said splicing contact in a said aperture to make electrical contact to said terminal contact.
Claim 2
Dependent Claim
273 words
An electrical connector for connection of pairs of wires to other pairs of wires, said connector comprising: a terminal block, said terminal block comprising a base having means for supporting a plurality of wires transversely thereof, a cover adapted to fit on the base, said cover having a plurality of terminal contacts for making connection to wries supported by the base and for enclosing the ends of the wires in the base, said cover having apertures affording access to said contacts, and said cover having location means about said apertures for polarizing pairs of said apertures; and a plurality of plugs for making contact with said contacts in said terminal block, said plugs comprising an insulative body, said body having opposite ends and a hinged cap supported on one end, a thin metal splicing contact supported in said body with opposite end portions, one end portion of said contact being a tuning fork contact portion adapted to make electrical connection with said terminal contacts and the other end portion being an insulation displacing contact portion adapted to make electrical connection to a jumper wire, said cap having means for facilitating connection between a said jumper wire and said other end portion of said splicing contact, having an aperture therein affording access to said insulation displacing contact portion, and having location means mounted thereon to afford proper location of a second plug on said cap, the other end of said body having means for mating with said location means of said cover for positioning said one end portion of said splicing contact in a said aperture to make electrical contact to said terminal contact.
