Brush carrier plate for automobile radiator fan motor

Abstract

The invention discloses a brush carrier plate for an automobile radiator fan motor. The brush carrier plate comprises an insulation brush carrier plate body and an electric conduction connecting plate, wherein four brush box mounting holes are uniformly distributed in the circumference of the brush carrier plate body; the connecting plate is plastically packaged in the brush carrier plate body, and comprises a first electric conduction section, a second electric conduction section, a third electric conduction section and a fourth electric conduction section which are used for correspondingly and electrically connected with brushes on the brush carrier plate body one to one, wherein the first electric conduction section and the second electric conduction section are connected with each other end to end, the third electric conduction section and the first electric conduction section are connected with each other end to end, and the fourth electric conduction section and the second electric conduction section are connected with each other end to end; and the tail end connection section of the first electric conduction section and the second electric conduction section, the tail end connection section of the third electric conduction section and the first electric conduction section, the tail end connection section of the second electric conduction section and the fourth electric conduction section and the head end connection section of the first electric conduction section and the second electric conduction section are all exposed out of the brush carrier plate body. The brush carrier plate has strong universality, not only is suitable for different variable-speed motors to use, but also is reasonable in internal wiring, and has a compact motor structure.

Description

technical field [0001] The invention relates to a brush holder board, in particular to a brush holder board for a fan motor of an automobile radiator. Background technique [0002] The car radiator fan mainly relies on the motor to drive the fan to rotate to dissipate heat. The basic principle of motor rotation is that the current-carrying conductor will be subjected to force in the magnetic field. One function of the brush holder plate inside the motor is to fix and install the carbon brush assembly, and the other function is to arrange the circuit and connect the carbon brush to the circuit. However, the structure of the current brush holder board is unreasonable, and it mainly has the following shortcomings: 1. Since the motor of the car radiator fan may have high, medium and low speed regulation or high and low speed regulation, the number of working carbon brushes inside the motor It is different, so the wiring is also different. Motors of different specifications requ...

Problems solved by technology

However, the structure of the current brush holder board is unreasonable, and it mainly has the following shortcomings: 1. Since the motor of the car radiator fan may have high, medium and low speed regulation or high and low speed regulation, the number of working carbon brushes inside the motor It is different, so the wiring is also different. Motors of different specifications require different brush holders, resulting in more specifications of brush holders, which cannot waste the cost of mold opening for the production of brush holders, and the versatility of brush holders is not strong. ; 2. Due to the current common brush holder board, the terminal setting is not reasonable, resulting in many and chaotic wiring, which affects the performance of the motor
