Abstract
Abstract Techniques for terminating a plurality of free-ended insulated electrical conductors in respective insulation-piercing contacts carried in respective parallel channels of an electrical connector include supporting the connector on a base with the channels exposed to receive the respective conductors, and moving an insertion tool generally parallel to the connector to sequentially insert the conductors within the respective channels and insulation-piercing contacts. The connector may advantageously comprise a notched ridge, with each notch in communication with a respective channel for preparatory alignment before insertion. The entire terminating apparatus resembles a credit card impression mechanism with a wheeled carriage supported to transverse a base in opposite directions. In one embodiment, a wire cutter, supported by the carriage, advances in front of the insertion tool to cut the ends of the wires before insertion. In this embodiment, the insertion tool performs the insertion operation upon return of the carriage. In a second embodiment, the insertion tool includes the wire cutter and operates to cut the wires contemporaneously with insertion thereof. In another embodiment, a wire cutter is carried between a wire pulling and seating member and the insertion tool, whereby the individual wires are snugged in each channel, and then cut to a predetermined length before insertion. In each embodiment, the insertion tool resembles a gear having insertion members as gear teeth. In the first two mentioned embodiments, the gear is a cylindrical rotatable member, while in the third embodiment, a sector gear is pivotally mounted for rotation of less than a complete revolution.
