Push-in wire connector

DETAILED DESCRIPTION This invention relates to push-in electrical connectors of the type wherein the stripped ends of electrical wires are pushed into the connector for the purpose of making electrical and mechanical connection between the wires.
A primary object of the invention is an electrical connector having a conductive clip of relatively simple design which is convenient to fabricate.
A further object of the invention is an electrical connector having a pin and socket arrangement on its exterior surface allowing stacking of multiple, like connectors.
Yet another object of the invention is an electrical connector of the type described having a conductive clip made of a bimetallic strip which is configured so as to increase the clamping force on connected wires when the clip is heated by electric current.
Another object of the invention is an electrical connector which is as small as possible for a three-piece structure.
Another object of the invention is an electrical connector with which connections can be rapidly and easily made.
Another object of the invention is a wire connector which can accommodate different size wires in one unit.
Another object of the invention is an electrical connector having a conductive clip with individual fingers which can operate independently to engage the conductors of the wires inserted into the connector.
The fingers may have V-shaped notches formed on the ends of the fingers to grip the conductors inserted into the connector.
A further object of the invention is an electrical conductor having a conductive clip comprising first and second portions.
The first portion is a flat plate.
The second portion is a U-shaped piece cantilevered from the end of the base and extending toward the plate.
The U-shaped piece is located adjacent the openings for the wires.
There are holes in the U-shaped piece permitting entrance of the wire conductors.
These and other objects will appear from time to time in the following specification, drawings and claims.
