Apparatus for affixing a strain wire into the wiring of flexible electric conduit
First Claim
1. A connector for connecting an electrical conduit having a strain wire to a junction box, said connector comprising a tubular portion extending within the junction box upon assembly, further comprising a longitudinal slot within at least the tubular portion, and a locking device for engaging the tubular portion, wherein the strain wire is placed within the slot and the locking device urges the strain wire against a surface of the junction box.

Abstract
A junction box connector and resulting assembly are disclosed that facilitate the inclusion of a strain wire. The strain wire relieves the load placed upon the cable or flexible conduit and cable combination that extends between the junction box and another similar connection. In a preferred embodiment, a connector that has a section extending inside the junction box is provided with a longitudinal slit, and the strain wire is placed within this slit. A locking device such as a threaded nut presses the wire down against the side of the junction box, creating a mechanical clamping effect, thereby providing an appropriate connection able to resist loads placed upon the structure. Preferably, the present invention is used with flexible conduit and the flexible conduit encapsulates an integral strain wire. In certain embodiments, the flexible conduit is filled with fire resistant material and marked with standard units of length.
