  • Patent number: 4002391
    Abstract: An insulation slicing terminal, stamped from electrically conducting sheet material, has a base portion and two cantilevered legs extending from the base portion providing opposed side edges between which a conductor is positioned. The top edge and side edge of each leg intersect at an abrupt angle to form insulation slicing edges, the two top edges forming a shallow Vee formation. An initial small gap is provided between the side edges by a first swage on one leg near the junction with the base portion. A further swage on one of the legs nearer the top of the leg acts to prevent movement of the conductor out of the terminal once the wire is inserted past the further swage. As a further feature, the shallow Vee formation, of the top edges, has an apex prior to slitting which is a radiused flat, permitting off-center tolerances on slitting without detrimentally affecting the insulation slicing edges.
