ABSTRACT:
The present invention relates to an assembly for protecting motor leads extending between an electric motor shell and an external control unit or power source. The present invention in one form includes a fitting configured for insertion into a notch formed in a motor shell and for coupling to a plastic conduit or sheath which protects the motor leads. The fitting includes a boss and a notch interfitting portion. An opening formed in the boss and interfitting portion is sized to have motor leads extend therethrough. A groove formed in the interfitting portion is sized to have inserted therein the walls forming the notch in the motor shell. The outer diameter of the fitting boss is sized to be inserted into a flexible plastic conduit. Protuberances, such as partial threads, on the exterior surface of the boss provide that when the boss in inserted into the flexible conduit, the boss is not easily separated from the conduit, even at elevated operating temperatures. The motor leads extend, for example, from the motor stator, through the fitting opening, into the flexible conduit, and to an external control unit or power source. The flexible conduit may extend the entire length of the leads between the fitting and the control unit or power source housing. The fitting and conduit protect the internal motor components and the motor leads against exposure to water, oil and dirt.
