Disclosure of Invention

In order to solve the above problems, an object of the present invention is to provide an integrated brush holder assembly with a tail cap and a brush holder body, which improves the assembling efficiency of the carbon brush holder and the brush holder body.

In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides an assembly is held to integral type brush, includes the brush holder body of doing the motor tail-hood concurrently and the carbon brush frame of copper product, be provided with the spacing constant head tank of motor shaft on the interior bottom surface of brush holder body the symmetry both sides of brush holder body are equipped with the installation pipe of square frame shape respectively, the hole of installation pipe with carbon brush frame phase-match, carbon brush frame latch is intraductal at this installation, the front end of carbon brush frame is close to the constant head tank.

The outer side wall of the carbon brush holder is provided with a convex part, the installation pipe is provided with a clamping groove opposite to the convex part, and the convex part is buckled in the clamping groove after the carbon brush holder is inserted into the installation pipe in place.

Protruding part is in including setting up first bump and the second bump that the interval set up on the lateral wall of carbon brush holder, the draw-in groove is rectangular form, the carbon brush holder inserts the back that targets in place in the erection tube, first bump and second bump are put into in the draw-in groove, first bump with draw-in groove one end inner wall looks butt, the second bump with the other end inner wall looks butt of draw-in groove.

The inner wall of the brush holder body is provided with compression convex strips which are uniformly distributed on the circumference, and the height of the compression convex strips is gradually reduced along the direction from the opening of the brush holder body to the inner bottom surface.

And a lead through groove is formed in the position, outside the brush holder body, of the mounting pipe.

The utility model discloses a this kind of structure, with the brush hold the body and do the motor tail-hood after, can directly install the brush body at the motor afterbody, saved the installation of tail-hood, improved assembly efficiency, installation pipe eye-splice on carbon brush holder and the brush body is connected simultaneously, its convenient and reliable more of operation further improves the assembly efficiency of carbon brush holder and brush body and the reliability of structure.

The invention is further described with reference to the accompanying drawings and the detailed description.

Drawings

FIG. 1 is a bottom view of an embodiment of the present invention;

FIG. 2 is a top view of an embodiment of the present invention;

fig. 3 is a side view of the mounting tube in accordance with an embodiment of the present invention.

Detailed Description

The present invention will be specifically described below by way of examples.

As shown in fig. 1-3, this embodiment discloses an integral type brush holder assembly, including brush holder body 1 and the copper carbon brush holder 2 who doubles as the motor tail-hood, be provided with the spacing constant head tank 11 of motor shaft on the interior bottom surface of brush holder body 1, be equipped with the installation pipe 3 of square frame shape respectively in the symmetry both sides of brush holder body 1, the hole and the carbon brush holder 2 phase-match of installation pipe 3, carbon brush holder 2 is inserted and is detained in this installation pipe 3, and the front end of carbon brush holder 2 is close to constant head tank 11.

Be equipped with protruding part 21 on the lateral wall of carbon brush frame 2, be equipped with the draw-in groove 31 relative with protruding part 21 on the installation pipe 3, carbon brush frame 2 inserts the installation pipe 3 and puts in place the back, and protruding part 21 buckle is in draw-in groove 31. By adopting the design, the carbon brush holder 2 and the installation pipe 3 can be more conveniently and reliably matched in a buckling way.

Protruding part 21 is including setting up first bump 211 and the second bump 212 that the interval set up on the lateral wall of carbon brush holder 2, and first bump 211 and second bump 212 are the same circular bump of structure, and draw-in groove 31 is arc for its both ends of rectangular form, and carbon brush holder 2 inserts the back that targets in place in the installation pipe 3, and first bump and second bump 212 are put into draw-in groove 31, and first bump 211 and draw-in groove 31 one end inner wall looks butt, and second bump 212 and the other end inner wall looks butt of draw-in groove 31. The structure is more reasonable by matching the inserting buckle of the carbon brush holder 2 and the installation tube 3 with the rectangular clamping groove 31 through the first salient point 211 and the second salient point 212, and the positioning of the carbon brush holder 2 is more reliable.

The inner wall of the brush holder body 1 is provided with compression convex strips 12 which are uniformly distributed on the circumference, and the height of the compression convex strips 12 is gradually reduced along the direction from the opening of the brush holder body 1 to the inner bottom surface. By adopting the structure, the structure of the brush holder body 1 can be more compact when the brush holder body is used as a tail cover of a motor and is connected with a motor shell.

A lead through groove is arranged at the position of the mounting tube 3 outside the brush holder body 1. Through this direction logical groove can make the better placing of copper wire braid of carbon brush afterbody and be connected with the carbon brush frame, improve the reliability of carbon brush work.

Adopt above-mentioned technical scheme, hold the body 1 with the brush and do the motor tail-hood after, can directly hold body 1 with the brush and install at the motor afterbody, save the installation of tail-hood, improved assembly efficiency, the installation pipe 3 eye-splice on carbon brush holder 2 and the brush holder body 1 is connected simultaneously, its convenient and reliable more of operation further improves the assembly efficiency of carbon brush holder 2 and brush holder body 1 and the reliability of structure.
