ABSTRACT:
A grounding shielded cable connector assembly is disclosed which is easily assembled and establishes a highly conductive path to ground through two mechanical junctions in the assembly. The assembly is adapted to provide good mechanical and electrical connections between a shielded cable and a grounded metal enclosed cabinet while maintaining adequate protection against deleterious aspects of the environment. A mechanical junction between a cable shield and a cable coupling is achieved by a spring clip and retaining means structure of the coupling to establish a highly conductive electrical junction. A mechanical connector junction between the cable coupling and a cabinet connector, adapted to secure the cabinet connector on a cabinet, is established by a threaded connection. As the cable coupling and cabinet connector are screwed together a high conductivity butting junction is established between them. A hollow plug is threadably connected to the cable coupling and provides a sealed mechanical connection between a cable sheath and the assembly. An `O` ring seal provides environmental protection on the interior of the assembly by being trapped between surfaces on the plug and cable coupling.
