Abstract: Device for connecting a branch connector to an insulated main conductor has a body made from a strip of metal that is a good electrical conductor. This body is cut and folded to a U-shape cross-section comprising a web, two flanges and lugs for connecting the branch conductors. The U-shape cross-section part includes two slots adapted to be forced-fitted to the insulated main conductor to cut the insulation and make the electrical connection.

Abstract: A device for interconnecting conductors in a group of electrical conductors includes a casing having at one end an opening adapted to receive a complementary member. It is adapted at the other end to receive a connecting strip. In its back it has a partition with two series of channels passing through it. The connecting strip is bent from a flat blank of a good electrical conductor to form a U-shape comprising flanges and a core. Parallel tangs perpendicular to the core of the U-shape are cut out from the flanges. The device further comprises a cover with latching devices adapted to cooperate with corresponding latching devices on the casing to lock the connecting strip against the partition by pressing against the outside of the core of the connecting strip.
