Abstract

The present invention discloses a carbon brush holder, and relates to the technical field of brush holders. The carbon brush holder comprises an annular base and a housing fixedly connected on the annular base, the housing comprises a conductive tube and an insulation housing fixedly connected on the conductive tube, a carbon brush is inlaid in the conductive tube, and a wire is electrically connected on the carbon brush and is punched out of the insulation housing. The technical problem is solved that open circuit of the carbon brush is easily generated in the connection process, and the open-circuit risk is reduced.

Description

technical field [0001] The invention relates to the technical field of brush holders, in particular to a carbon brush holder. Background technique [0002] Carbon brushes, also called electric brushes, are widely used in many electrical equipment as a sliding contact. Carbon brushes are mainly made of graphite, fat-impregnated graphite, and metal graphite. A carbon brush is a device that transmits energy or signals between the fixed part and the rotating part of a motor or generator or other rotating machinery. It is generally made of pure carbon and a coagulant. A spring presses it tightly on the rotating shaft. When the motor rotates, the electric energy is transmitted to the coil through the commutator. Because its main component is carbon, it is called a carbon brush, which is easy to wear. It should be regularly maintained and replaced, and carbon deposits should be cleaned. [0003] The existing carbon brush holder includes an annular base and a housing fixedly conn...
