  • Downhole electrical connector for submersible pump
    Patent number: 4859200
    Abstract: A pothead for connecting electrical cable to a downhole submersible pump motor utilizes primary and secondary seals. The pothead includes a rigid plastic insert that is forced into the shell. The insert has passageways extending through it for the conductors of the electrical cable. An elastomeric compression sleeve is located in each passageway and encircles each conductor. A locking ring is secured in the passageway and bears against the compression sleeve to cause the compression sleeve to seal around the conductor. The interior of the shell is filled with an elastomeric material as a secondary seal.
