Embodiment Construction

[0025] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0026] Such as Figure 1 to Figure 6 As shown, the brush buckle 11 provided by the embodiment of the present invention is used to be installed between the brush holder 13 and the outer edge of the end cover body 12 for positioning the brush assembly 14 installed in the brush holder 13 against the top. The brush buckle piece 11 is a U-shaped sheet member made of elastic insulating material, which includes an abutment portion 111 that fits with the outer end surface of the brush holder 13 facing the outer edge of the end cover body 12, two abutment portions 111 along the Two bent portions 112 extend...

Abstract

The invention is applicable to the technical field of motors and discloses a brush buckle sheet, a motor end cover with the same and a motor. The brush buckle sheet is used for being installed between a brush frame and the periphery of an end cover body so as to allow a brush assembly installed in the brush frame to be pressed and positioned. The brush buckle sheet is a U-shaped sheet component made of elastic insulation material and comprises a pressing part, bending parts and first buckling parts, wherein the pressing part fits the outer end face, towards the periphery of the end cover body, of the brush frame, the bending parts bend and extend towards the two sides of the brush frame along the two ends of the pressing part, and the first buckling parts are arranged on the bending parts and used for being in buckled connection with the brush frame. As the brush buckle sheet is made of insulation material, the potential safety risk of leakage of a motor body due to the fact that the creepage distance between the brush buckle sheet and the inner wall of the motor body is not enough is eliminated; and the first buckling parts are in buckled connection with the brush frame, thus improving the stable reliability of installation of the brush buckle sheet and improving the stable reliability of performance of the motor with the brush buckle sheet.

Description

technical field [0001] The invention belongs to the technical field of motors, and in particular relates to a brush buckle, a motor end cover with the brush buckle and a motor with the motor end cover. Background technique [0002] A motor with a commutator generally has a corresponding brush on its motor end cover for contacting and matching with the commutator. The brush is generally installed in the brush holder, and one end of the brush is in contact with the outer wall of the commutator, and the other end points to the outer edge of the motor end cover. During the operation of the motor, the commutator will rotate with the rotor, and the brushes will not rotate. In this way, there will be severe friction between the commutator and the brushes. Therefore, after the motor runs for a certain period of time, the brushes will It is shortened by wear; and we know that the brush needs to maintain contact with the commutator to achieve its working performance. In order to ens...
