ABSTRACT:
A strain-relief clamp for securely engaging a multi-conductor cable between two relatively movable pieces at a position closely adjacent the connections of the conductors to the terminals of an electrical plug, receptacle, or other wiring device. A first piece includes a hollow, cylindrical shell having an integrally formed, generally semi-cylindrical portion internally of the shell at one end, the wiring device being secured in the other end. A second piece is positioned inside the shell with an arcuate surface opposing an inwardly facing, curved surface of the semi-cylindrical portion of the first piece. A pair of screws pass through openings in the shell and semi-cylindrical portion of the first piece and are threadedly engaged in the second piece. A pair of flexible tabs or wings extend integrally from the second piece to contact the curved surface of the first, being positioned between the metal screws and the conductors to form a dielectric barrier as the screws are tightened to grip the cable tightly between the curved surfaces of the first and second pieces.
