Description

Automobile generator carbon brush frame protection structure Technical Field The utility model relates to the technical field of generator carbon brush holders, in particular to a protective structure of an automobile generator carbon brush holder. Background The carbon brush holder is an important part in the motor, and is used for applying pressure to the carbon brush which is in sliding contact with the surface of the commutator or the collector ring through the spring so that the carbon brush holder stably conducts current between the fixed body and the rotating body, and the brush holder and the carbon brush are both very important parts for the motor. The carbon brush in the automobile generator has a simple structure, is only used as a carrier for conducting current, but when the copper ring is matched with the copper ring to rotate and conduct electricity, partial dirt enters the machine body and finally adheres to the surface of the copper ring due to external factors, the copper ring with the dirt easily wears the inner end of the carbon brush in a high-rotation-speed state, and once the carbon brush is worn and aggravated, the conductivity between the fixed body and the rotating body is reduced, so that the service life of the generator is seriously influenced. In view of this, a protection structure for a carbon brush holder of an automobile generator is designed to solve the above problems.
