Title: Solderless electrical connector for connecting a plurality of insulated wires

Abstract: A solderless electrical connector is disclosed having the capability of connecting a plurality of insulated wires. The connector includes a metallic contact having a plurality of keyhole-shaped slots. As the wire is inserted, the mouths and associated shoulders of these slots pierce and strip the insulation from the conductor. As the wire is forced further into the keyhole slot, the inner walls of the slot are caused to bear into the surface of the conductor. The connector further includes a means for positioning and retaining the wires to be interconnected, a means for enclosing the connection, and a means for protecting the connection from torsional and tensional stresses.
