Abstract
Abstract A tap connector for tapping branch conductors to conductors of a bus cable has an insulating base, a plurality of tap contacts retained in the base and an insulating cover. Each contact is a flat metal plate having three parallel, closely spaced legs extending from one edge. The two outer legs lie in a common plane and the center leg lies in a plane parallel to the common plane and is offset therefrom creating conductor connection slots between the center leg and each of the outer legs for a conductor of a bus cable and a tapping branch conductor at an angle to the bus conductor.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
285 words
A tap connector for tapping branch conductors to conductors of a bus cable, comprising: an insulating base, a plurality of tap contacts retained in said base, each said contact comprising a flat metal plate having three parallel, closely spaced legs extending from one edge, the two outer legs lying in a common plane and the center leg lying in a plane parallel to said common plane and offset therefrom by a distance at least equal to the thickness of said plate, the outer legs being spaced from the center leg to create two parallel sided conductor connecting slots of lesser width than the conductors to be connected for electrically connecting a branch conductor to a conductor of a bus cable, said contact legs being relieved at their free ends along their edges facing the conductor connecting slots to define wire retention areas of a width greater than the conductors to be connected to engage the insulation on the conductors and the inner edge of one outer leg and the adjacent edge of the center leg of each contact being relieved further along the conductor connecting slot a distance generally equal to the diameter of the insulated conductors to be connected, said contacts being positioned in said insulating base to connect a plurality of parallel, equally spaced conductors of a bus cable to a plurality of parallel equally spaced branch conductors at an angle to the conductors of the bus cable, and an insulating cover having receptacles for the ends of said tap contacts to permit said cover to force the bus and branch conductors into said conductor connecting slots in said contacts when said cover is placed over said base and they are pressed together.
