Abstract

An electrical distribution system for lighting and the like including a generally C-shaped channel forming a track having guide shoulders on the exterior of the bight portion thereof, and inwardly extending lip portions adjacent the opening thereof for receiving and captively retaining a multiple conductor insulated cable within the channel. A first channel-shaped connector member is provided with inwardly extending guide portions configured for slidably engaging the shoulders of said channel member, the depth of the first connector member being sufficient for receiving therein a second connector member. The second connector member has a body portion with shoulders thereon spaced a distance less than the distance between adjacent edges of the lips of the open end of the channel member. Conductive barbs extend in generally perpendicular relation to the surface of the body portion intermediate the shoulders thereof, the barbs being at positions corresponding to the position of the conductors to be engaged. A pair of tapered leg portions extend from the body portion at positions for abutting the side walls of the channel member. A sliding coaction between the first and second connector members with the second connector member positioned with the shoulders thereof between the lips of the opening urges the barbs into piercing engagement with the insulation therebeneath for establishing electrical contact between the barbs and the conductors.
