Abstract

The invention is directed to a multipole connector assembly for connection of a low voltage to an electric appliance (E) of personal use, with a plug (6) insertable into a socket (5) and with contactable contact elements (1 to 4, 10, 20, 30, 40) for a polarized voltage transfer, wherein the socket (5) and the plug (6) are constructed as polygonal profile bodies (M1 to M12) reversible from one plug-in position to at least one further plug-in position about a symmetry axis (S), wherein provision is made on each polygonal profile body (M1 to M12) for contact elements (1 to 4, 10, 20, 30, 40) of at least one first pole (+) and one second pole (−), wherein the contact elements of the first pole (+) and of the second pole (−) are provided on the polygonal profile body faces of the polygonal profile bodies (M1 to M12) in alternating sequence in a direction of rotation (U), and wherein on at least one of the polygonal profile bodies (M1 to M12) the contact elements have a relatively large contact face for making large-surface contact with the contact face of an engaging contact element (1 to 4, 10, 20, 30, 40).
