Prefabricated brush holder assembly for use in small electric motors

Claim 1

A brush holder assembly designed for prefabrication by an automatic machine and further designed to be used with commutators of small electric motors used in fuel pumps and the like, comprising: a carrier plate manufactured of an insulating material, the carrier plate having a central opening with a periphery, the opening being so sized that a commutator of a small electric motor can be received therein and further having a first side and a second side; two hollow brush carriers fixed on the first side of the carrier plate so as to abut the periphery of the opening at opposed points; two carbon brushes, each located within a corresponding one of the brush carriers and slidably movable therewithin so as to be abuttable against a commutator received within the opening; two brush springs fixed on the first side of the carrier plate and cooperating with the brushes in a manner that each brush spring can urge a corresponding one of the brushes against a commutator received within the opening; to brush leads, each attached to a corresponding one of the brushes; anti-interference components located on and having lead ends bent toward the first side of the carrier plate; two power leads each having an end shaped into an eyelet form, which ends are fixed in the first side of the carrier plate and are electrically connected to at least one of the anti-interference components; and a plurality of electrically conductive grommets fixed in the carrier plate and electrically connecting the brush leads, the power leads and the lead ends of the anti-interference components into an electrical network.
