Abstract
A discharge head having an internal electrical receptor for receiving and supporting an electrical connector, preferably for submersible turbine pumps. The electrical connector is protected by liquid immersion. The electrical connector is inserted into an internal electrical receptor within the discharge head. The electrical connector electrically couples a motor, which is attached to the discharge head, to control electronics via wiring coupled to the electrical connector. A liquid inlet is formed at the base of the discharge head between an outer wall of the discharge head and the inner electrical receptor that supports the electrical connector. One or more supporting structures in the form of ribs connect the outer wall to the electrical receptor forming a plurality of orifices that receive liquid from the motor. The support structures contain indentations to form an annular ring flow path that allows liquid to completely surround the electrical connector and/or electrical receptor.
