ABSTRACT:
Two conductive mating halves of a connector hood include facing inserts of resilient conductive materials. A cable, having shielding conductive braid or foil exposed on a surface thereof is contacted in passing between the inserts. A low-resistance electrical path is provided between the shielding and the conductive connector hood by a resilient conductive material for resisting escape of radio-frequency interference from the connector hood. In one embodiment of the invention, a foam material with parallel embedded metallic wires is employed for the resilient conductive material. The wires are preferably oriented for conduction between the connector hood and the shield braid or foil on the cable with substantially no conductive paths parallel to the axis of the cable. Facing, metallic spring-type strain-relief devices in the connector hood provide strain relief as well as enhance the resistance to radiation of radio-frequency interference.
