Abstract
The utility model discloses a commutator for motors, which comprises a commutator segment and a molding compound 3, wherein, the commutator segment comprises a commutator segment body 1 and an inner hook 2, and the commutator segment body 1 and the inner hook 2 are connected to form a K-shaped structure. The utility model solves the problem of small contact area between an original commutator segment and the molding compound, and connecting strength and reliability, and adhesive strength of the commutator segment and the molding compound are enhanced. Compared with the prior art, the phenomenon of segment jump and fly in the original commutator is eliminated, the service life of the commutator is extended, and the utility model is particularly suitable for motors having high rotary speed.
Description
One, technical field
The utility model relates to a kind of motor commutator.
Two, background technology
The interior hook of the commutator segment of existing commutator is commonly swallowtail-shaped structure, thereby the contact area of its commutator segment and moulding compound is just less, and promptly the adhesive force between commutator segment and the moulding compound is less.This commutator is easy to generate film dancing, film flying phenomenon in motor runs up process, and the grade of spark that causes motor to produce increases, even burns motor itself.
Three, utility model content
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of commutator that can increase the contact area of commutator segment and moulding compound is provided.
The purpose of this utility model realizes by following technical solution: a kind of commutator, comprise commutator segment, moulding compound, wherein commutator segment comprises commutator segment body and interior hook, described commutator segment body and interior hook be connected to form " K " font structure.
After adopting the utility model structure, because " K " font structure that is connected to form of commutator segment body and interior hook has increased the contact area of commutator segment and moulding compound, thereby make linking intensity between commutator segment and the moulding compound and reliability, adhesive force obtain bigger raising.Therefore, the utility model compared with prior art can be eliminated film dancing, the film flying phenomenon of former commutator, prolongs the useful life of commutator, is specially adapted to pot motor.
Four, description of drawings
Fig. 1 is the structural representation of the utility model commutator.
Fig. 2 is the A-A cutaway view of Fig. 1.
Fig. 3 is the B-B cutaway view of Fig. 2.
Five, embodiment
Below in conjunction with accompanying drawing and execution mode the utility model is described in further detail.
With reference to Fig. 1, Fig. 2, Fig. 3 as can be known, the utility model commutator comprises commutator segment, moulding compound 3, and wherein commutator segment comprises commutator segment body 1 and interior hook 2, described commutator segment body 1 and interior hook 2 be connected to form " K " font structure.
The utility model not only is confined to illustrated overall plastic hook commutator, also comprises overall plastic tank commutator, half plastotype commutator (containing mica sheet) or the like certainly.
Claims (1)
1, a kind of commutator comprises commutator segment, moulding compound 3, and wherein commutator segment comprises commutator segment body 1 and interior hook 2, it is characterized in that: described commutator segment body 1 and interior hook 2 be connected to form " K " font structure.
