Abstract
A stacking and orientation independent multiple contact plug and socket electrical connector has a central connector body with a 'plug' extending outward on one face, and a 'socket' recessed inward on an opposite face. The plug and socket are aligned along a common axis, but are on opposite faces of the central connector body. The plug is an electrically insulated post extending outward from the central connector body and having multiple electrically conductive circular contact rings encircling the post. The socket is a cylindrical recess into the central connector body designed to accept the plug of another similar connector. The socket has multiple electrical wiper contacts spaced along an electrically insulating inner wall of the recess for contacting to the circular contact rings of a post.
