Abstract
A brush card assembly 10 includes a brush card member 12, conductive contacts 14 provided on the brush card member, and brushes 16 mounted to be electrically in contact with the conductive contacts. The assembly 10 also includes brush box 18 associated with each of the brushes. Each brush box includes an integral spring 24 constructed and arranged to bias an associated brush to contact a commutator, and an integral retainer 26 constructed and arranged to exert pressure on the associated brush once the brush is disengaged from the commutator.
Claims20
A brush card assembly comprising:
- a brush card member,
- conductive contacts provided on the brush card member,
- brushes mounted to be electrically in contact with the conductive contacts, and
- a brush box associated with each of the brushes, the brush box including an integral spring constructed and arranged to bias the associated brush to contact a commutator, and an integral retainer structure constructed and arranged to exert pressure on the associated brush once the brush is disengaged from the commutator during operation of a motor which employs the brush card assembly, to minimize arcing between the brush and associated brush box,
- wherein the brush box, spring and retainer structure comprise a single part.
A brush card assembly comprising:
- a brush card member,
- conductive contacts provided on the brush card member,
- brushes mounted to be electrically in contact with the conductive contacts, and
- a brush box associated with each of the brushes, the brush box including an integral means for biasing the associated brush to contact a commutator, the brush box including integral means for exerting pressure on the associated brush once the brush is disengaged from the commutator during operation of a motor which employs the brush card assembly, to minimize arcing between the brush and associated brush box,
- wherein the brush box, means for biasing and means for exerting pressure comprise a single part.
A brush box assembly for a brush motor, the assembly comprising:
- a brush constructed and arranged to contact a commutator of a motor, and
- a brush box receiving the brush, the brush box including an integral spring constructed and arranged to bias the brush to contact the commutator, the brush box including an integral retainer structure constructed and arranged to exert pressure on the brush once the brush is disengaged from the commutator during operation of a brush motor which employs the brush box assembly, to minimize arcing between the brush and associated brush box,
- wherein the brush box, spring and retainer structure comprise a single part.
