One blade of each contact pair is supported along one of its edges to provide for a twisting action and reliable electrical contact as the blades are engaged. Transverse movement of the housings is effected by an actuator member mounted on one housing by an integral hinge and movable to a latched position wherein it forces the other housing member to a transverse position thereby closing each of the individual pairs of contacts.

Abstract: A threaded coupling in which a first disc element is formed with a discontinuous internal thread and a second disc element is formed with a cooperable discontinuous external thread. The coupling includes a mounting plate element juxtaposed adjacent the disc element. Aligned openings are provided in the plate, disc and mounting block elements. A stud element completes the coupling and is rotatably mounted within the opening in the mounting block element but is provided with a depending projection which engages within the opening in the disc element. Rotation of the stud element thus threads the disc element into the plate element to provide a unitary assembly. Rotation of the stud element in the other direction unthreads the disc element and uncouples the assembly.
