An electrical terminal is disclosed for use in the insulation displacing termination of conductors having substantially any center spacing. The terminal is provided with two spaced apart and substantially parallel side beam members which define a conductor receiving channel therebetween. Each side beam has at least one insulation piercing extension perpendicularly formed therefrom to extend into the channel toward a corresponding extension formed from the opposite side beam. As the conductor is moved laterally of its axis and into the channel, the edges of the corresponding insulation piercing extensions serve to pierce the insulative covering of the conductor and establish electrical and mechanical contact between the terminal and the conductor. Termination tooling for use in terminating the conductor is also disclosed and includes a pressing bar, and a block having supportive means for reinforcing the terminal side beams during the termination procedure.
An electrical terminal for effecting insulation displacing termination of an electrical wire formed by a conductor covered with insulation, said terminal comprising:
An insulation displacement terminal for engaging electric wire having a conductive core within an insulation covering, comprising an elongate formed conductive member having a mating first end and an oppositely directed wire securing second end to which the wire is to be connected, said wire securing end having a base and first and second pairs of opposed jaws upstanding therefrom at axially spaced locations along the base, the first pair of jaws includes sidewalls upstanding from said base along axial fold lines, edges formed on flanges extending inwardly from the sidewalls, indent means formed in both the base and sidewalls extending crosswise of the axial fold lines thereby strengthening the sidewalls and increasing axial restraining of the wire relative to the terminal, said edges converging adjacent the base to be spaced apart transversely of the channel a distance slightly less than the diameter of the conductive core, the second pair of jaws having opposed tabs angled toward the base and each other, whereby when said wire with the insulation covering thereon is aligned over the exposed pairs of jaws and forced transversely therebetween and against the base, said edges of the first pair of jaws displace the insulation covering and frictionally contact the conductive core to establish an electrical and mechanical connection between the terminal and wire and also to axially restrain the wire relative to the terminal, and the second pair of jaws are crimped to overlie and trap the insulation covering against the base and transversely restrain the wire relative to the terminal.
