The tool includes a pair of handles which combine to form a hand grip for manipulation of the tool. When the handles are closed, a support element is displaced from its illustrated home position within the head portion, engages a connector and displaces it forwardly against a die to crimp the connector element to the multi-conductor wire positioned in the connector and effect electrical contact between individual contact elements in the connector and the conductors in the multi-conductor wire. The tool also provides for stripping the end of the wire to fit within the connector. Guide elements with upwardly open yokes on one handle accommodate the wire, and blade elements on the other handle provide a slicing action on opposite sides of the sheath of the wire as the blades engage the sheath as the handles are closed so that the sheath may be stripped to expose the conductors for insertion into the connector.

1. A hand tool assembly for applying a selected connector to a given flat multi-conductor wire comprising a sheath and a plurality of co-planar conductors, said selected connector adapted to accommodate said given wire and having a number of stalls corresponding to the number of conductors in said wire, contact elements displaceably mounted in said stalls adapted to penetrate the conductors of said multi-conductor wire, and two anchor parts operable to be displaced in said connector to crimp respectively against said sheath and said conductors, said tool comprising a pair of handles and a head having a transverse guideway and a movable support operable to be longitudinally displaced in a stroke from a home position toward said guideway upon closing movement of said handles and away from said guideway to said home position upon opening movement of said handles, said tool having ratchet means limiting movement of said handles to insure a minimum closing stroke of said movable support, and stop means comprising a stop member on one of said handles and a yoke member on the other of said members mating with the stop means upon closing movement of said handles to define a maximum closing stroke, a die slidably mounted in said guideway and means to releasably position said die in said guideway laterally of said head, said guideway positioning said die spaced from the home position of said support to receive said selected connector therebetween, said die being dimensioned to cooperate with said selected connector, having a multi-leaf plunger registering with the contact elements of said connector when positioned in said guideway and being operable when said handles close to displace the contact elements into contact with said conductors upon completion of said minimum closing stroke, and additional plunger means registering with said anchor parts to crimp said parts to said sheath and said connectors upon completion of said minimum stroke; said tool including wire stripper means between said handles for stripping the sheath from said conductors at the free end of the wire to permit penetration of said conductors into said stalls, said stripper means including an elongated slot means in said yoke member to receive said wire and position said coplaner conductors along the centerline of said slot means, said yoke means comprising a pair of guide members spaced-apart longitudinally of said wire, and slicing means on said stop member having a pair of blade edges adapted to engage said sheath between said guide members to move generally parallel to said centerline of the slot means to slice into the sheath of the wire along opposite sides of said conductors, so that upon axial withdrawal of said wire from said blade edges, the sheath is stripped from the conductors. 2. A hand tool assembly according to claim 1 which is adapted to apply one of a plurality of different connectors to a wire adapted to fit with said one connector, said assembly including a separate die for each different connector, and register means to position the connector so that contact elements of the connector are in registry with the multi-leaf plunger when the die for said connector engages said connector. 3. A hand tool assembly according to claim 2 wherein said head has a detent adjacent said guideway, and each of said separate dies has a spring detent assembly cooperable with said detent to comprise said releasable positioning means. 4. A hand tool assembly according to claim 2 wherein each of said separate dies has outwardly projecting guide portions slidable in said guideway, and side portions and centering pin means projecting longitudinally of said head toward said movable support to receive therebetween the connector for said die to comprise said register means. 5. A hand tool for use with a flat multi-conductor wire comprising a sheath and a plurality of co-planar conductors, comprising a pair of handles and wire stripper means for stripping the sheath from said conductors at the free end of the wire, said stripper means including upstanding yoke means carried by one of said handles comprising a pair of guide members spaced-apart longitudinally of said wire and having slot means with co-planar centerlines to receive said wire and position said coplanar conductors along the coplanar centerlines of said slot means, and slicing means actuated by the other of said handles comprising an element displaceable between said guide members and having a pair of blade edges adapted to move generally parallel to and on opposite sides of the plane of said centerlines to slice into the sheath of the wire along opposite sides of said conductors between said guide members, so that upon axial withdrawal of said wire from said blade edges, the sheath is stripped from the conductors at the free end of the wire. 6. A tool according to claim 5 wherein the leading edges of said blade edges are beveled to facilitate the slicing operation. 7. A tool according to claim 5 wherein one of said guide members has a pair of separate indexing surfaces spaced from the path of movement of said blade edges and adapted to recieve the free end of the wire to gauge the length of the sheath stripped from the wire. 8. A method of stripping the sheath from the terminal end portion of a flat multiconductor wire having a sheath and a plurality of coplanar conductors disposed along the center plane of the flat wire by particularly severing the sheath at a selected point spaced from the free terminal end of the wire and holding the terminal end portion of the sheath beyond said selected point while withdrawing the wire, thereby withdrawing the conductors from within the severed terminal end portion of the sheath, said method comprising the steps of providing a pair of supports having elongated slots with parallel centerlines, positioning said multiconductor wire on its edge between said supports with its center plane coincident with the centerlines of said slots and with the selected point positioned between said supports, providing a pair of knives having parallel knife edges spaced apart a distance greater than the thickness of the conductors in the central plane and less than the thickness of the multiconductor wire including the sheath, displacing said blades parallel to said central plane and across the width of said multiconductor wire at said selected point between said supports so that the blade edges partially sever the sheath without severing the conductors, maintaining said blades in position between said supports while withdrawing said multiconductor wire axially from said supports whereby said blades retain the terminal end portion of the sheath to effect separation of the sheath portion from the conductor along the length of the wire between said selected point and its free terminal end.
