Abstract: The present invention relates generally to electrical connectors and more particularly to the electrical connectors which are commonly known as cable bonding clamps. Cable bonding clamps are used for providing continuity of the conductive shielding of a communication cable at splice points so as to carry electrical current across the splice and to ground the conductive shield at termination points.

Abstract: A method and assembly are disclosed for terminating a plurality of signal and ground or shield conductors of a ribbon cable. The assembly includes a contact plate having a plurality of termination tabs each joined to a carrier strip and a ground member. The active signal conductors of the cable are electrically connected to each of the tabs while the ground conductors are connected to the ground member. The terminated cable is then insert molded in an integral dielectric housing, leaving only the carrier strip and portions of the termination tabs and ground member exposed. The carrier strip is then severed from the connector, thereby electrically isolating the termination tabs from each other and the ground member. The resulting connector is mechanically and electrically reliable and may be interfaced with compatible electrical components without damage to the individual terminations.
