  • Adapter for two core cable
    Patent number: 5435756
    Abstract: One end of a two-core twisted pair cable 30 having two twisted wires 32 and 34 in a common jacket 36 is prepared. An insert 20 having a pair of semicylindrical halves 22a and 22b connected by a hinge 21 in which a central groove 25 and a branched groove 26 are formed is used. An insert subassembly is prepared by placing one wire 32 connected to the central contact in the central groove 25 of the insert 20, and by placing the other wire 34 in the branched groove 26 and bringing outside its exposed conductor 38. This insert subassembly is inserted in the outer ferrule 13 of the metal shell 12 of the BNC connector 10, after which the ferrule is crimped, thus connecting the conductor 38 to the metal shell 12.
