Abstract
An improved wire terminal is provided in which an internal coiled spring wire clamping member is opened with the usual clockwise twist of the wire terminal when wires are inserted into the wire terminal, with an intermediate portion of the spring initially contacting the wires as they are inserted into the wire terminal such that the clockwise rotation opens an upper spring portion anchored at its end to the wire terminal. In one embodiment, the portion of the spring contacting the inserted wires is open at the top and has a parallel running portion, such that with the wires held in position manually, the rotation in the clockwise direction permits further insertion of the wires up through the parallel portion of the spring and into a cavity at the top of the wire terminal. Release of the wire terminal causes the spring to collapse on itself to squeeze the wires together, thereby preventing dislodging of the wire terminal as by vibration. The wire terminal assembly includes a housing having an interior portion which is enlarged to accommodate the expansion of the internally carried spring, and in one embodiment, includes inwardly-projecting tabs adapted to contact the inserted wires to further prevent the wires from coming out of the wire terminal once inserted.
