Abstract
The utility model relates to a cold extruded all-plastic commutator with rings. The commutator comprises a copper commutator body, wherein a commutator lifting sheet is arranged at the position close to the edge, on the left side of the commutator; a plurality of insulating grooves are uniformly formed, at the position close to the edge, on the right side of the commutator; a plastic component is arranged in the commutator body; and reinforcing rings are arranged at the contact position of the top of the commutator body and the plastic component and at the contact position of the bottom of the commutator body and the plastic component. The commutator has the advantages that: the reinforcing rings are adopted, so that a strengthening effect is achieved, the strength of the plastic component is improved, the commutator is prevented from flying off when running at an over speed, and the over speed property is improved by 20 to 30 percent.
Description
Technical field
The utility model relates to the overall plastic band commutator of a kind of cold-extruded, belongs to the automobile starting motor field.
Background technology
It is round that commutator is that several contact chips surround, and connects epitrochanterian each contact respectively, and two electrodes that the outside connects are called brush and contact with it, simultaneously wherein two of contact only.Principle is, after coil passes through electric current, can be under the effect of permanent magnet, by attracting and the repulsive force rotation, when it forwarded to the magnet balance, the contact that was leading to originally on the electric more corresponding commutator of line was just separated with brush, and brush is connected on the contact of that group coil correspondence that produces motive force, that does not stop like this repeats down, and DC motor has just been turned over; Existing commutator is made of commutator segment and its inner working of plastics, when running up, occurs the commutator phenomenon of dispersing easily.
The utility model content
The purpose of this utility model provides the overall plastic band commutator of a kind of cold-extruded, in the time of avoiding over-speed operation effectively, and the disperse generation of phenomenon of commutator.
The purpose of this utility model is to be achieved through the following technical solutions:
The overall plastic band commutator of a kind of cold-extruded, comprise copper commutator main body, the place of keeping to the side, left side of commutator main body is provided with commutator riser, the place of keeping to the side, right side of commutator main body evenly is provided with some insulation tanks, the mounted inside of commutator main body has working of plastics, and the contact position of the top of commutator main body and bottom and working of plastics is equipped with reinforcing ring.
The beneficial effects of the utility model are: adopted reinforcing ring, not only played reinforcement effect, and improved the intensity of working of plastics, when having avoided over-speed operation, commutator disperses, and overrunning property has improved 20% ~ 30%.
Description of drawings
With reference to the accompanying drawings the utility model is described in detail below.
Fig. 1 is the upward view of the overall plastic band commutator of the described cold-extruded of the utility model embodiment;
Fig. 2 is the cutaway view of the overall plastic band commutator of the described cold-extruded of the utility model embodiment.
Among the figure:
1, commutator main body; 2, commutator riser; 3, insulation tank; 4, working of plastics; 5, reinforcing ring.
Embodiment
Shown in Fig. 1-2, the overall plastic band commutator of the described a kind of cold-extruded of the utility model embodiment, comprise copper commutator main body 1, the place of keeping to the side, left side of commutator main body 1 is provided with commutator riser 2, the place of keeping to the side, right side of commutator main body 1 evenly is provided with some insulation tanks 3, the mounted inside of commutator main body 1 has working of plastics 4, and the contact position of the top of commutator main body 1 and bottom and working of plastics 4 is equipped with reinforcing ring 5.
