ABSTRACT:
A method of making a two-stage twist-on wire connector comprising the steps of forming a housing; placing a spiral thread on an interior of the housing with the spiral thread having an open end and a closed end with a diameter of the open end of the spiral thread larger than the diameter of the closed end, the spiral thread diametrically converging in an axial direction toward the closed end; inserting a lubricant into the closed end of the spiral thread; inserting a plurality of wire ends to be splice into the open end of the spiral thread; twisting the plurality of wires and the wire connector to draw the plurality of wire ends proximate the closed end of the spiral thread to improve the continuity of said the splice; and applying the lubricant to the spiral threads by the twisting engagement of the wires with respect to the spiral threads.
