Problems solved by technology

[0002] The AMT motor is an important functional part in the automobile gearbox. The brush holder assembly of the motor usually does not have a connector structure, which requires a large number of lead wires. The wiring is very complicated and takes up a lot of space, which brings many problems to the production of the motor. Inconvenient; most of the protection of the motor shell is waterproof and dustproof through O-shaped sealing rings, which can achieve limited effects, and the assembly process is relatively cumbersome; the printed circuit board of the motor is fixed by positioning posts and screws or buckles. Screws often have defects such as slipping teeth or screw hole cracks, while buckle fixing often has buckle deformation, inaccurate positioning, loosening or even falling off of printed circuit boards, etc. There are many problems in mold development and assembly processes. Difficulty, increases development costs, hinders development of AMT motors

Abstract

The invention discloses an AMT motor brush carrier assembly, and the assembly comprises a brush carrier and a printed circuit board. An outer ring of the brush carrier is wrapped by a rubber sealing part, and the brush carrier is provided with a plugging structure. The brush carrier is provided with a terminal in an injection molding manner, and the printed circuit board is electrically connected with the brush carrier through the terminal. The assembly does not need to employ a lead-out wire structure, can avoid wiring troubles, and enhances the dustproof and waterproof functions.
