ABSTRACT:
An electrical connector includes a grounded cable joined to a coupler, with an electrically insulative casing molded around adjoining ends of the cable and coupler. The coupler is adapted to be electrically connected to an electric receptacle and includes an insulative insert containing rear electrical contacts connected to respective signal lines of the cable. The rear contacts are electrically connected to front contacts which are to receive the male contacts of the receptacle. An electrically conductive ferrule is mounted on the insert and extends rearwardly therefrom to a connection point with a ground wire of the cable. A cylindrical front portion of the ferrule extends across a gap between the casing and a threaded nut which is freely rotatably mounted on the insert, to provide ESD (electro-static filed) shielding for the cable. The nut, formed of an electrically conductive material, contacts the ferrule and maintains ground continuity between the ground wire and the receptacle.
