ABSTRACT:
Apparatus for distributing electic current, especially in a low voltage track lighting system includes: (i) a cable in the form of a rigid rod having coaxial conductors and male and female couplings at its opposite ends allowing the cable rod to be connected end-to-end with other similar cable rods, and the inner conductor having a spring loaded contact at one end; (ii) a coupling unit which may be used to connect rotatably one cable rod to another cable rod or an appliance, the unit having relatively rotatable housing parts defining respective male couplings at the opposite ends of the unit, and contacts arranged to project axially at the opposite ends, the contacts being connected by a flexible braided conductor and urged apart by a coil spring; and (iii) a coupling including a track with a channel having a connector carried by an inner wall and side walls with inturned flanges, a connector (which may be a cable rod or coupling unit) with a screw threaded end through which a contact projects, and a nut which engages behind the flanges and presses the end of the connector and the contact against the track conductor.
