ABSTRACT:
A brush holder assembly has a body portion with a through opening and an externally accessible lateral opening communicating with the through opening and forming an internal shoulder within the body portion. A brush insert is slidably received within the through opening of the body portion and has an integral connection tab received within the lateral opening. The tab is bent over the shoulder to preclude axial withdrawal of the insert in one direction away from the body. A brush lead has a quick-connection terminal slidably received over the tab to make electrical connection to the insert within the lateral opening of the body. A brush is slidably received within the insert and extends beyond one end of the insert to engage a commutator. The other end of the insert is covered by a shunt cap, and a shunt is disposed between the shunt cap and the brush. A removable brush cap is secured to the outer end of the body, and a conical spring is disposed between the shunt cap and the brush cap. The enlarged end of the conical spring is seated within a blind axial bore in the brush cap, and the center of the spring bears against the shunt cap.
