Clamp bushing for securing an electrical cable to an electrical outlet box

Abstract

A cable clamp assembly comprises a bushing member adapted to receive an electrical power cable, tubing or the like, has a pair of jaw members adapted to fit through a cable entry port in the wall of an outlet box. One jaw is fixedly secured to the bushing while the other is formed on a movable arm member. A lug portion of the bushing provides a cavity which serves as a guide for travel of the arm and a threaded fastener passes through the lug and threadably engages the arm to move the arm. A biasing member associated between the bushing and the screw urges the arm member away from the fixed jaw. The biasing means may be generally U-shaped and located generally over the lug, with the free ends of its leg portions abutting the exterior of the bushing member and an aperture in its base portion to receive the screw. Alternatively, the biasing member may be a relatively flat resilient member affixed at one end to the exterior of the bushing and spaced from the bushing at its other end which is formed with a hole to receive the fastener. The flat biasing member may, instead, be affixed at one end to the interior of the bushing while its other end abuts the shank end of the screw.
