POTHEAD CONNECTOR WITH ELASTOMERIC SEALING WASHER

A pothead connector for an electrical submersible pump motor includes a housing. A first insulating block is disposed within the housing and has passages for receiving insulated conductors of the power cable. The passages in the first insulating block have counterbores on an second end. A second insulating block is also disposed within the housing. The second insulating block has passages through which the insulated conductors pass. The second insulating block also has protrusions on a first face that are concentric with the counterbores and shaped to fit within the counterbores in the first insulating block. An elastomeric washer is positioned within each of the counterbores. A fastener rigidly secures the second insulating block to the first insulating block, forcing the protrusions against the elastomeric washers to cause the washers to seal around the insulated conductors.
