Abstract: An apparatus for simultaneously terminating a plurality of insulated conductors in the insulation piercing contacts of a multiple contact electrical connector is disclosed. The apparatus includes means for mounting a connector in conductor receiving position, means for aligning the conductors adjacent individual contacts of the connector, means for positioning an insertion member adjacent the contacts, and resilient means forcibly engaged by the insertion member during the termination process. The apparatus allows sufficient displacement of the resilient means by the insertion member so as to accommodate various transverse dimensions of electrical connectors without the necessity of any adjustment.
