ABSTRACT:
A ground lead connection is provided to electrically ground a motor armature shaft. In one embodiment the device has a motor housing in which is mounted a bearing. An armature shaft is journaled in the bearing and a ground lead is attached to the bearing. The bearing is provided with a counter bore socket which receives a terminal from the ground lead. The terminal includes a ferrule and a plug which has flared fingers. When connected, the plug engages the bore of the socket and the fingers engage the counter bore to permanently prevent removal of the terminal from the socket. The shaft is thereby grounded via the bearing without the need for numerous parts.
