Patent ID: 8905727

Claim:
A submersible well pump assembly, comprising: a pump; an electrical motor cooperatively connected with the pump for driving the pump, the motor having a motor housing that is filled with a dielectric motor lubricant, the motor having an internal motor lead immersed in the motor lubricant; a seal/equalizer section mounted to the motor, the seal/equalizer section being in fluid pressure communication with the motor lubricant and with well fluid surrounding the motor for reducing a pressure difference between the motor lubricant and the well fluid surrounding the motor; a female motor connector comprising a connector housing containing at least one chamber, the female motor connector being connected to an outer surface portion of the motor housing, the chamber being filled with a female motor connector dielectric fluid; wherein said at least one chamber comprises an inner chamber and an outer chamber containing the inner chamber; the female motor connector dielectric fluid comprises an inner dielectric fluid in the inner chamber and an outer dielectric fluid in the outer chamber; the inner dielectric fluid is sealed from the outer dielectric fluid; at least one female pressure compensation device mounted to the female motor connector and in fluid pressure communication with the at least one chamber for reducing a pressure difference between the female motor connector dielectric fluid and the well fluid surrounding the motor; the internal motor lead extending from within the motor housing into the at least one chamber and having an electrical contact on an end within the at least one chamber; a power cable having at least one conductor to supply electrical power to the motor; a male motor lead connector on an end of the power cable, the male motor lead connector being releasably secured to the female motor connector; at least one of the conductors of the power cable extending into the female motor connector housing and electrically mating with the electrical contact of the internal motor lead when the male motor lead connector is secured to the female motor connector; and a seal around the internal motor lead that seals the motor lubricant from the dielectric fluid in the at least one chamber.
