Abstract
An insulating, resilient plug body having a forward portion of reduced diameter is sealingly received in a stepped hole of similar dimensions formed in a submersible housing. A plurality of spaced electrical conductors extend through the sealed interior of the plug. A pregrounding strip is carried on the surface of the forward portion of the plug and extends axially back through the larger rearward portion of the plug body and ends in an integral ground wire terminal behind the plug body. As the plug body is inserted into the hole, the grounding strip is wedged into contact with the wall of the hole, thus making electrical contact with the housing via the wall itself or an electrical terminal on the wall before the power connections are made. The electrical connector is preferably designed for a submersible pump motor, and the inner portion of the hole for the connector is formed through a sealed stator.
