Motor brush assembly
First Claim
1. A motor brush assembly, comprising:
- a stamped and formed lead frame including a large central aperture, plate sections for engagement with respective metal brush holders, pairs of first electrical terminals, and a pair of second electrical terminals each having conductor-connecting means for electrical connection with power wires, one of each pair of said first terminals being electrically connected to a respective said plate section and the other of each pair of said first terminals being electrically connected to a ground contact extending outwardly from said lead frame, said lead frame having first severable sections between the terminals of each said pair of first terminals;
a dielectric housing member secured onto said lead frame with conductor-connecting means of said first and second terminals extending outwardly from said housing member for electrical connection to respective said leads, said housing member having a circular wall around said large central aperture of said lead frame defining a central opening, and said housing member having first openings exposing said first severable sections;
said metal brush holders disposed in brush holder channels on said housing member and having integral lug sections secured to respective said plate sections in electrical engagement therewith, and including brush-receiving sections in communication with said central opening; and
capacitors having leads electrically connected to conductor-connecting means of respective said pairs of first electrical terminals to provide noise suppression, said ground contact extending outwardly from said housing member, and said first severable sections being severed thereby separating said lead frame into separate electrical sections.

Abstract
A motor brush assembly comprises a stamped and formed lead frame including electrical terminals at spaced locations and a dielectric housing member secured onto the lead frame with the electrical terminals being exposed and accessible for electrical termination to electrical power wires and lead wires of capacitors and inductors. Cavities are located in the housing member in which the inductors are disposed. Metal brush holders are positioned in brush holder locations on the housing member and lugs thereof are electrically stapled onto the lead frame. Openings are located in the housing member exposing severable sections of the lead frame separating the lead frame into separate brush circuits. If inductors are to be disposed in the circuit path between the terminated power leads and the brush holder locations, the respective severable sections are also severed which interconnect the lead frame between the associated pairs of terminals corresponding to each inductor. A ground terminal extends outwardly from the housing member.
