Trailer hitch

Abstract

A ball-type hitch half is mounted on a towing vehicle, and a socket is mounted on a pivotable arm attached to the towed vehicle. The socket includes a shoulder surrounding the socket including a plurality of radially spaced pins. The ball has a neck that extends downward. Surrounding the neck is a peripheral collar on which a plurality of arcuately extending electrical contacts are provided. The pins surrounding the socket on its peripheral shoulder are spring biased in the downward direction such that they are forced into engagement with the arcuate contacts on the collar which is spring biased upward. When the socket is installed and locked over the ball, the contact pins are spring biased into contact with the arcuate electrical contact areas such that for any rotative or pivoted position of the towed vehicle with respect to the towing vehicle, the pins maintain contact with the arcuate contacts.
