ABSTRACT:
Panel-mount ground termination apparatus for terminating the outer shielding conductor of an electrical cable and for simultaneously mounting the cable to a panel. The apparatus includes a housing mounted to the panel and having an axial aperture for receiving the cable to be terminated; a flexible termination member having a plurality of inwardly extending, electrically conductive prongs positioned within the housing aperture and surrounding the cable; a compression member having a tapered, inner compression surface; and a housing closure member threadable onto the housing. As the closure member is threaded onto the housing, the compression member is urged into the housing aperture between the outer surface of the termination member and the sidewall of the housing aperture. The tapered compression surface of the compression member engages the outer surface of the termination member, compressing the termination member inwardly and driving the plurality of prongs into the cable and into engagement with the outer conductor of the cable. The prongs are preferably arranged in pairs, and the termination member includes curved surface portions which deform as the prongs are driven into the cable, causing the prongs of each prong pair to turn toward one another to firmly retain the outer conductor therebetween.
