ELECTRICAL COMPONENT
First Claim
1. An electrical component capable of making solderless electrical connection to insulated wire conductors of a three conductor cable covered with a nonmetallic sheath without requiring preliminary stripping of the insulation or severing of the wire conductors and having a wire-receiving base member, a body member engageable with the base and containing conductive contact elements having projecting therefrom resilient contact plate portions slotted to provide an open-mouth slot adapted for forceful entry of a wire conductor, and holding means for holding the base and the body together;
- wherein the base member comprises;
an elongate insulating block longitudinally channeled along one face to provide an enlarged channel at one end capable of receiving the sheath covered wires, said channel branching into three smaller intermediate channels capable of receiving insulated wires exposed by cutting away a short portion of said sheath, and converging again as an enlarged channel at the other end, the central intermediate channel being substantially straight and the outer intermediate channels being oppositely arcuate, said intermediate channels each having a wire-supporting floor and parallel walls, said base being transversely grooved across each of said intermediate channels with grooves of adjacent channels being nonaligned to provide grooves in said floor and walls for slidably receiving an appropriate one of said contact plate portions with the mouths of the slots of said plate portions centered in relationship to the wire-supporting floors of the intermediate channels, whereby insulated wire conductors supported in said intermediate channels are brought into permanent positive electrical connection with appropriate contact plate portions upon engagement of the body with the base.
