Abstract
A submersible electrical motor that drives a pump has an electrical connector receptacle base. A plug opening extends from the base into an interior of the motor and has a side wall extending around a plug opening axis. An electrical connector plug at an end of a motor lead has a nose portion that stabs into the plug opening and is surrounded by the side wall. An inward facing shoulder formed in the side wall faces inward into the motor. An outward facing shoulder on the nose portion faces outward from the motor interior and registers with the inward facing shoulder when the nose portion is fully received within the plug opening. A retainer inserts into engagement with the inward and outward facing shoulders to prevent outward movement of the plug in the plug opening. The retainer may be a pin or a ring.
