Problems solved by technology

[0002] Motors, especially motors with brushes, will generate a lot of noise when running at high speed. In order to meet the requirements of electromagnetic compatibility standards, noise reduction must be performed on these noises. The noise reduction method generally requires the installation of grounding terminals to prevent high-frequency interference. The signal forms a low-resistance path, thereby suppressing high-frequency interference, thereby reducing the noise generated by the motor. The existing grounding terminal is fixed on the casing by welding, which is cumbersome and complicated to operate, and the production cost is high, and the grounding terminal is easy to fall off and cause damage. cause performance failure

Embodiment Construction

[0034] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0035] like Figure 1 to Figure 5 As shown, the built-in structure of a motor grounding terminal of the present invention includes a casing 1 and a brush holder 2 connected to the casing 1, and the first terminal 3 and the second terminal are arranged on both sides of the brush holder 2 respectively. Two terminals 4, the brush holder 2 is provided with a grounding terminal 5 on one side close to the first terminal 3, one end of the grounding terminal 5 is in contact with the first terminal 3, and the other end of the grounding terminal 5 is in contact with the first terminal 3. A casing 1 , an end cover 6 is provided at one end of the casing 1 close to the brush holder 2 .

[0036] The brush holder 2 is matched and installed in the casing 1, the end cover 6 is assembled on the bottom of the casing 1 and covers the brush holder 2, and the first terminal 3 and the sec...

Abstract

The invention relates to the technical field of motors, in particular to a built-in structure of a motor grounding terminal, which comprises a casing and a brush holder connected with the casing. A first terminal and a second terminal are respectively arranged on two sides of the brush holder. A grounding terminal is arranged on the side, close to the first terminal, of the brush holder. One end of the grounding terminal abuts against the first terminal, and the other end of the grounding terminal abuts against the casing. An end cover is arranged at the end, close to the brush holder, of the casing. The built-in grounding terminal mode is adopted, traditional welding operation can be omitted, the grounding terminal is in stable and reliable contact with the casing and the terminals, loosening and falling are not prone to occurring, the operation is convenient, and the appearance is simple and attractive.
