Abstract
The present invention is a slip ring assembly for an automotive alternator, or other appropriate rotary electric machine, which includes at least one slip ring, a plastic body mounting the slip ring, at least one electrical terminal connected to the slip ring and supported by the body and at least one reinforcement ring. The reinforcement ring is operatively disposed on the plastic body and operatively adapted so as to strengthen the slip ring assembly against catastrophic failure resulting from loads applied to the slip ring assembly while it is under severe operating conditions. By employing such a reinforcement ring, the present slip ring assembly can be produced inexpensively with plastic bodies made from polyester and like plastics and yet still be able to withstand operating loads applied under high rotational speeds, elevated temperatures and other adverse conditions.
