Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Refer to fig. 1 to 2. Carbon brush installation component, including carbon brush box 1 and carbon brush subassembly 2, carbon brush box 1 is equipped with U type mounting groove 11, and in U type mounting groove 11 was located to carbon brush subassembly 2, spacing hole 12 had been seted up to the both sides of U type mounting groove 11, was equipped with arch 3 on the carbon brush subassembly 2, and arch 3 card is gone into in spacing hole 12, cooperatees with spacing hole 12. Therefore, in the assembling process, the carbon brush component 2 is inserted into the U-shaped mounting groove 11, and the protrusion 3 is clamped into the limiting hole 12, so that the carbon brush component 2 can be fixedly mounted in the carbon brush box 1, and the assembling process is convenient to mount and simple to operate.

The carbon brush assembly 2 comprises a carbon brush 21, a pressing block 22, a rope braid 23 and a spring 24, the carbon brush 21 and the pressing block 22 are respectively connected with two ends of the rope braid 23, the spring (24) surrounds the rope braid (23), the two ends of the spring are respectively abutted against the carbon brush 21 and the pressing block 22, and the protrusions 3 are located on two sides of the pressing block 22. The rope braid 23 is a copper braid formed by intertwining a plurality of thin copper wires, and one end of the rope braid is embedded into the carbon brush 21 and pressed and fixed; after the spring 24 surrounds the braid 23, the other end of the braid 23 is welded and fixed to the pressing block 22.
