Abstract:
1. An electrical conduit to junction box connection system for releasably connecting a junction box and a conduit, wherein the junction box has a box interior surface, a box exterior surface, a box thickness, and is formed with a knockout extending from the box interior surface to the box exterior surface having a knockout diameter and a knockout edge, and the conduit has a conduit interior surface, a conduit exterior surface, a conduit thickness, and a conduit leading edge, comprising: a body having a distal end, a proximal end, a body exterior surface, and a body interior surface, wherein the body interior surface defines an inlet diameter, an outlet diameter that is coaxial with the inlet diameter, and wherein the body includes a box engagement region that cooperates with the junction box, a nut engagement region, and a conduit engagement region that cooperates with the conduit, wherein: a compression nut having a nut interior surface having a plurality of nut threads that cooperate with the nut engagement region threads, a nut exterior surface, a nut contact edge having a nut contact surface, and a nut free edge, wherein after insertion of the leading tab and the follower tab through the knockout by angling the body such that a central axis is not orthogonal to the knockout and then passing the leading tab through the knockout and bringing the knockout edge in contact with the root surface so that the follower tab can pass through the knockout, the body is drawn tight to the junction box by rotating the compression nut such that cooperation of the nut threads and the nut engagement region threads force the compression nut toward the leading tab and the follower tab so that the leading tab centering flank directs the knockout edge onto the leading tab centering ledge thereby substantially centering the central axis in the knockout and pinching the junction box between the compression nut and the leading tab and follower tab thus releasably securing the body to the junction box.
