US Patent 7575458 Hi-dielectric debris seal for a pothead interface

A connector for connecting electrical power to a well pump motor has cable and motor connector portions that mate with each other in a connected position. The connector portions have insulating members, each of which has a number of passages and an end face. Electrical contact members are mounted in each of the passages. The ones in the cable connector portion protrude past the end face of the insulating member. An end face seal surrounds each of the protruding contact members and is deformed by engagement of the end face of the motor insulating member when the cable and motor connector portions are in the connected position.
