  • Prefabricated brush holder assembly for use in small electric motors
    Patent number: 4342934
    Abstract: A brush holder assembly is designed so as to be prefabricated in automatic assembly machines. All the components of the assembly are located on a single side of an insulated carrier plate. The components are connected together by means of electrically conductive grommets which are fixed in the carrier plate. A vibration-resistant holder assembly is thus formed which can be assembled with less cost than other such assemblies which require hand labor.
