Abstract
An electrical cable connector for use in a knockout opening of an electrical box or the like includes a cam element with a slot therein arranged to receive the tip of a screwdriver transverse of its rotational axis so as to permit the application of a significant torque on the cam with a minimal force to thereby securely wedge the cable in the connector body and prevent its removal. This connector features a tubular body with an enlarged inner end to permit its installation into a knockout opening from the inside of the box, an integrally molded pressure pad opposite the cam element to permit the connector to accommodate several sizes of cable, and snap locks designed to defeatably hold the cam element selectively either in its open or its locked positions.
