ABSTRACT:
A coupling guard insures that a plurality of plugs are coupled to plural receptacles in a desired sequence. An array of cam rings which rotate in unison with the rotation of mating plugs are designed to be locked against rotation unless the rings are rotated in the desired sequence. In one embodiment, cover plates coupled to the cam rings cover the entrance to the adjacent receptacles and are removed from the entrance of the receptacles by rotation of the cam rings.
