Coaxial cable assembly

Claim 1

An electrical assembly comprising: a coaxial cable having an end portion, a center conductor, a dielectric surrounding said center conductor, and an outer conductor surrounding said dielectric, an insulating jacket surrounding said outer conductor, and said outer conductor being stripped away from said dielectric over said cable end portion; a conductive ferrule having a passageway therethrough somewhat larger in size than said dielectric, said cable end portion projecting through said passageway, said ferrule having first and second axial portions, said first portion having a frusto-conical external surface around said cable end portion, said first portion being axially slotted to form resilient prongs; a back-nut surrounding said first and second ferrule portions; a conductive body to which said back-nut is threaded, said body having a frusto-conical internal surface to mate with said ferrule frusto-conical surface, said back-nut being so threaded and constructed that said ferrule prongs lie in pressure contact with said body internal surface to make good electrical contact therewith; and securing means to hold said cable jacket and outer conductor and said ferrule second portion in fixed positions relative to each other and in pressure contact and in electrical contact with each other, wherein said securing means includes a member surrounding said cable jacket and outer conductor and said ferrule second portion in a manner to clamp the same together, and wherein said back-nut has a flange close to and surrounding said cable and forming an annular pocket therein, a sealing gasket gland in said pocket close to said flange and said cable, said ferrule having a shoulder, said member being annular and in axial compression between said ferrule shoulder and said gasket gland to cause said gasket gland to provide a seal between said back-nut and said cable.
