ABSTRACT:
A fluid-resistant brush holder assembly having a hollow metal cylinder body with internal threads at a first end and a second end forming a brush channel. An electrical connector having a first portion is mechanically and electrically connected to the body. A connecter tab extending away from the electrical connector is provided for making contact with an electrical power source. The outside surface of the body and the first portion of the connector are encapsulated in a molded nonconductive material. The molded nonconductive material provides the connector with structural rigidity and fixed orientation with respect to the body. A metal threaded cap having a hollow interior is provided for screwing into the interior threads in the body and capping the first end of the body. The head portion of the body cap seats against the body to seal the first end of the body. A brush cap is fitted into the hollow interior portion of the body cap. A spring and shunt wire are disposed between the brush cap and the brush for biasing the brush and for providing an electrical connection between the brush and the brush cap.
