1. An insulation displacement terminal having a slot formed between two members, the slot having side edges parallel to the centerline of the slot for establishing an insulation displacement termination to a wire encased in insulation and inserted laterally of its axis into the slot, each said member having a sharp point defined by converging inner and outer sloped edges at one end for penetrating the insulation surrounding said wire, where the lateral distance between said points is between 1 and 1.5 times the diameter of said wire and the slope of the inner sloping edge relative to the centerline of the slot is less than the slope of the outer sloping edge relative to the centerline of the slot, whereby the resultant force, normal to the centerline of the slot, tending to open the slot as the inner and outer sloping edges engage insulation surrounding the wire is reduced so that the tendency of the two members to spread apart as a result of engagement of the insulation with the inner and outer sloping edges is lessened whereby the slot edges make a more reliable contact with a wire upon insertion therein.
