Abstract: A tee shaped electrical connector for a pump such as a sump pump having a pump motor controlled by a float switch. A power cord carrying a plug on one end extends from one leg of the connector body. A float switch cord extends to the float from another leg of the connector. The third leg of the connector includes electrical contacts to which the power cord and float switch wiring extend. Electrical terminal pins for the motor leads project into a socket on the pump so that the contacts and terminals connect electrically when the connector is applied to the socket.

Abstract: An expanded foam material surrounds a relatively thin, metallic motor casing and forms a housing which supports the motor while providing a seal to preclude leakage of liquids into the motor casing and to prevent discharge of dielectric oil from the interior of the motor casing. During manufacture of the pump, the casing is placed within a mold and a portion of the mold structure complementally and firmly engages four radially spaced regions of the generally cylindrical motor casing. Next, a quantity of the initially pourable foam material is introduced into the space between the mold and the casing, and the material self-expands to a solidified, cured condition in firm, surrounding engagement with the motor casing.
