ELECTRICAL FIXTURE COUPLING AND SUPPORT APPARATUS

An electrical fixture support and current feed system includes an inverted metal track channel which is coupled to a junction box with converging side walls and houses in its upper part a longitudinal double channel insulator body. Nesting in each of the insulator channels is a longitudinal conductor bus having upwardly converging curved fingers resiliently urged into mutual engagement. The metal channel has grooves formed in the lower border of its inner faces. A plug assembly includes an insulator body member having an upper cavity closed by a hinged lid and supporting a first contact member with a first prong, a second contact member with a second prong and a first clip, and a second clip, the clips being located in the cavity. First and second conductors extend through a metal conduit depending from the body member and are connected to the first contact member and the second clip and a fuse is engaged by the clips. Outwardly sprung detent-carrying arms are located on the body member. The detents releasably engage the channel grooves when the plug registers with the metal channel and the prongs engage the bus fingers and upon insertion of the plug, the arms engage the track channel inner faces before the prongs engage the conductors.
