Abstract
Abstract In a method of manufacturing an electrical harness comprising wires connected to electrical terminals of a plurality of electrical connectors, according to a desired wiring pattern, each terminal comprises a wire connecting portion in the form of a slotted plate formed integrally with a contact portion in the form of an electrical receptacle. The wires are laid out on a wiring layout board with the aid of wire guiding posts to form a desired wiring pattern, with portions of the wires extending through notches in the housings of the connectors. The terminals are then inserted into through openings in the housings so that the wires received in the notches are captured by the slots of the terminals so that electrical connection is made between the terminals and the wires. When the terminals have been inserted into the openings in the housings, the receptacles are in line with the ends of the openings opposite to those through which the terminals were inserted, so that the receptacles can receive male members inserted through the former ends of the openings. The openings in the housings, contain abutments for forcing the wires into the slots of the terminals as the terminals are inserted into the openings.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
259 words
An electrical connector comprising an insulating housing, and a plurality of electrical terminals therefor, the housing having a plurality of terminal-receiving through openings having first and second ends, a wall of the housing being provided with notches each opening into an edge of the wall, the first end of each opening having therein an abutment opposite to such a notch, each terminal being adapted to be received in one of the openings and having a contact portion for mating with a complementary electrical terminal member and a wire connecting portion having means for piercing the insulation of an insulated wire to make electrical contact with the electrically conductive core of the wire, the contact portion and the wire connecting portion of each terminal being disposed opposite to one another with the insulation piercing means of the wire connecting portion directed towards the contact portion, each terminal being dimensioned to be inserted with its contact portion leading, through the first end of the opening to cause a wire laid in the notch associated with such opening to be forced by the abutment against the insulation piercing means of the wire connection portion of the terminal to cause the insulation piercing means to make electrical contact with the electrically conductive core of the wire, with the contact portion of the terminal aligned with the second end of the opening to mate with a complementary terminal member inserted through such second end, each terminal having means for cooperation with the housing to lock the terminal in its inserted position in the opening.

Claim 3
Dependent Claim
118 words
An electrical connector according to claim 1, in which the wire connecting portion of each terminal is U-shaped, a wire-receiving slot being formed in each arm of the U, the slots being aligned with each other, and both slots opening in the direction of the contact portion of the terminal so that upon insertion of the terminal into an opening of the housing, the arms of the U can straddle the abutment which is in the form of a saddle, so that the saddle forces the wire into both the slots of the wire connecting portion so that the edges of the slots pierce the insulation of the wire to engage the electrically conductive core of the wire.
Claim 4
Dependent Claim
103 words
An electrical connector according to claim 1, in which each abutment is in the form of a saddle which has a slot to receive the wire connecting portion which is in the form of a plate having a wire-receiving slot opening towards the contact portion of the terminal, the slot in the saddle opening into a wire engaging surface thereof, so that when the terminal is inserted into the opening, such surface forces the wire into the slot of the plate so that the edges of such slot pierce the insulation of the wire to engage the electrically conductive core of the wire.
Claim 5
Dependent Claim
153 words
An electrical connector according to claim 1, in which the openings of the housing are separated from one another by T-cross-section partitions which are elongate in the direction of insertion of the terminals into the openings, an arm of each partition extending across each opening, in the longitudinal direction of the housing, to provide the abutment of such opening and presenting a wire engaging surface in substantial alignment with the base of one of the notches, the wire connecting portion of each terminal being in the form of a plate having a slot opening towards the contact portion of the terminal, the slot being dimensioned to receive the arm when the terminal is inserted into the opening so that the wire engaging surface of the arm forces the wire into the slot whereby the edges of the slot pierce the insulation of the wire to engage the electrically conductive core of the wire.
Claim 6
Dependent Claim
169 words
An electrical connector according to claim 1, in which the notched wall of the housing projects from the housing beyond the first ends of the openings, each opening having a slot portion at its first end for receiving and confining the wire connecting portion of the terminal which is in the form of a plate having a slot opening towards the contact portion of the terminal, the slot portion of the opening communicating with and being juxtaposed with a second portion of the opening which is dimensioned for receiving the contact portion of the terminal which portion is in the form of a receptacle, the slot portion of the opening being positioned adjacent to the notched wall, and being bounded by wire engaging surfaces so that when the terminal is inserted into the opening, the wire engaging surfaces force the wire into the slot in the plate so that the edges of such slot pierce the insulation of the wire to engage the electrically conductive core of the wire.
