Pothead connectors for submersible motor head and methods of assembly thereof

摘要

A pothead connector for connecting a plurality of electrical cables to the terminal block of a submersible motor head is provided. A method of assembly of the pothead connector is also provided. The pothead connector comprises a housing that defines a plurality of passageways that extend in a longitudinal direction and are each configured to receive one of the electrical cables. Each passageway is further configured to receive a shroud that encircles the electrical cable within that one passageway. A first end of the shroud compresses a packing seal to form a liquid impermeable seal with each passageway and with the outer surface of the electrical cable. Each shroud is biased in the longitudinal direction to compress the packing seal by a plurality of spring stacks separated by a plurality of spacers. The second end of the shroud is capable configured to mate with a recess in the terminal block.
