Description

Commutator
Technical Field
The utility model relates to a commutator.
Background
The commutator is mainly used in the motor industry and mainly comprises a commutator body and commutator segments, wherein the commutator segments are directly injected on the surface of the commutator body. Due to the structural arrangement, the situation that the assembly of the commutator segment and the commutator body is not firm exists, and the commutator cannot be normally used. In order to enhance the assembly firmness of the commutator segments, the commutator segments are usually lengthened or widened for assembly, so that not only is the fixing effect achieved poor, but also the space for assembly on the commutator body is limited, and collision between adjacent commutator segments is easily caused, and the commutator is damaged.
SUMMERY OF THE UTILITY MODEL
To the not enough of prior art existence, the utility model aims to provide a better commutator of structural strength.
In order to achieve the above purpose, the utility model provides a following technical scheme:
a commutator comprises a commutator body, the commutator body is made into a disc shape by plastic injection molding, a shaft is arranged on the commutator body in a penetrating way, commutator segments are fixedly arranged on the shaft and are distributed along the circumference of the shaft in a clearance way, the shaft penetrates through the commutator body, the commutator segments are injected into the commutator body, the commutator segments are provided with elastic bending segments, the bending pieces are attached to the commutator segments before use, round holes are arranged on the bending pieces, insulating ropes are arranged in the round holes in a penetrating mode to connect all the bending pieces in sequence, the upper surface and the lower surface of the commutator body are both provided with a positioning plate, the positioning plates and the commutator body are integrally arranged, the commutator segment is divided into a commutator segment A and a commutator segment B, a bending segment on the commutator segment A is positioned at one end far away from the shaft, a bending segment on the commutator segment B is positioned at one end close to the shaft, and the length of the commutator segment A is greater than that of the commutator segment B.
The utility model discloses further set up to: the bending pieces and the commutator segments are integrally arranged, and the bending pieces are arranged in a triangular shape.
The utility model discloses further set up to: the commutator bar is made of silver-copper alloy material.
Through adopting above-mentioned technical scheme, add on the commutator segment and establish the piece of buckling, be equipped with the round hole on the piece of buckling, wear to establish the round hole through insulating rope, link together all annular pieces in proper order, then mould plastics in the circulator originally internally, can promote the assembly fastness of commutator segment and commutator body for the difficult emergence of commutator segment drops, promotes the operating mass of commutator.
Drawings
Fig. 1 is a sectional view of the structure of the present invention.
1. A commutator body; 2. a shaft; 3. a commutator segment; 4. bending the sheet; 40. a circular hole; 5. and (7) positioning the plate.
Detailed Description
The embodiment of the commutator of the present invention is further described with reference to fig. 1.
A commutator comprises a commutator body 1, wherein the commutator body 1 is made into a disc shape by plastic injection molding, a shaft 2 penetrates through the commutator body 1, commutator segments 3 are fixedly arranged on the shaft 2, the commutator segments 3 are distributed along the circumference of the shaft 2 in a clearance way, the shaft 2 penetrates through the commutator body 1, the commutator segments 3 are injection molded in the commutator body 1, elastic bent segments 4 are arranged on the commutator segments 3, the bent segments 4 are attached to the commutator segments 3 before being used, round holes 40 are arranged on the bent segments 4, insulating ropes penetrate through the round holes 40 and connect all the bent segments 4 in sequence, positioning plates are arranged on the upper surface and the lower surface of the commutator body 1 and are integrated with the commutator body 1, the commutator segments 3 are divided into commutator segments 3A and commutator segments 3B, the bent segments 4 on the commutator segments 3A are positioned at one end far away from the shaft 2, the bending piece 4 on the commutator segment B is positioned at one end close to the shaft 2, and the length of the commutator segment 3A is larger than that of the commutator segment 3B. The bending pieces 4 and the commutator segment 3 are integrally arranged, and the bending pieces 4 are arranged in a triangular shape. The commutator segment 3 is made of silver-copper alloy materials.
The bent pieces 4 on the commutator segment 3 are attached to the commutator segment 3 before being used, so that the commutator segment is convenient to transport and store, and the space can be saved. When using, will buckle piece 4 and carry out 90 degrees and buckle, be the mutually perpendicular state with commutator segment 3, then pass round hole 40 with insulating rope, connect gradually all the piece 4 of buckling, take all commutator segment 3 again and buckle piece 4 and mould plastics on commutator body 1, such structure setting can be so that commutator segment 3 is higher with commutator body 1's assembly fastness, the difficult condition that drops that takes place. The commutator segment 3 is divided into a commutator segment 3A and a commutator segment 3B, the bent segments 4 on the commutator segment 3A and the commutator segment 3B are different in position, the lengths of the two commutator segments are different, and the two commutator segments 3 are fixed in the commutator body 1 in a staggered manner, so that the fixing effect of the commutator segment 3 is better.
It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
