Abstract
An electrical submersible pump assembly has modules including a pump, at least one motor, and a pressure equalizer coupled to the motor. First and second ones of the modules have a threaded connection including a first adapter having threads. A second adapter mounted to the second module has a tubular body, a neck of smaller diameter than the body, an external shoulder at a base of the neck, a rim on the neck, and an external groove between the external shoulder and the rim. A collar is rotatably carried and axially movable on the neck, the collar being in threaded engagement with the threads of the first adapter, the collar having an internal groove. A split shoulder ring carried partly in the external groove and partly in the internal groove retains the collar on the neck and is biased into one of the grooves.
