Brush holder assembly

A brush holder assembly, comprising:

• an insulating body portion having an inner end and an outer end and further having a through opening internally threaded at its outer end, the body portion further having an externally-accessible lateral opening communicating with the through opening, an internal shoulder within the body portion adjacent to the lateral opening, a conductive brush insert slidably received within the through opening and having an integrally-formed connecting tab received within the lateral opening and bent over the internal shoulder, thereby precluding axial withdrawal of the insert in one direction away from the body, a brush lead, a quick-connection electrical terminal on one end of the lead, the terminal being slidably received over the tab to make electrical connection to the insert, the connection being disposed substantially within the lateral opening, thereby tending to protect against dirt and contaminants, the brush insert having a longitudinal passageway formed therein, a brush slidably received in the passageway and extending beyond one end of the insert, a shunt cap over the other end of the insert, a shunt between the shunt cap and the brush, an externally-threaded brush cap received within the internally-threaded outer end of the body, the brush cap having an internal blind axial bore formed therein, and a conical biasing spring between the brush cap and the shunt cap, the conical spring having an enlarged end coil portion seated in the blind axial bore of the brush cap, and further having a center portion bearing against the shunt cap, thereby tending to minimize turning movement of the shunt cap as the brush cap is threadably received within the body.
