Abstract
The utility model discloses a plane switching device made of full plastics, which comprises a switching sheet 1 and bakelite powder 2, wherein, the switching sheet 1 is perpendicular to the shaft line of the switching device, and the foot part 3 of the switching sheet 1 is provided with a claw-shaped structure. The utility model can make the contact strength between the switching sheet 1 and the bakelite powder reliable, the phenomena of skip page and fly sheet of the switching device are eliminated, the quality of the switching device is increased, and the service life is prolonged. The utility model is especially suitable for high rotary speed motors.
Description
One, technical field
The utility model relates to a kind of motor commutator, specifically relates to a kind of overall plastic flat commutator.
Two, background technology
The foot of the commutator segment of existing overall plastic flat commutator is commonly swallowtail-shaped structure, thereby the contact area of its commutator segment and phenolic moulding powder is just less, and promptly the adhesive force between commutator segment and the phenolic moulding powder 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.
Three, utility model content
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of overall plastic flat commutator that can increase the contact area of commutator segment and phenolic moulding powder is provided.
The purpose of this utility model realizes by following technical solution: a kind of overall plastic flat commutator, comprise commutator segment, phenolic moulding powder, and the axis of commutator segment and this commutator is perpendicular, and the foot of described commutator segment has the claw type structure.
After adopting the utility model structure, because the claw type structure that commutator segment foot has has increased the contact area of commutator segment and phenolic moulding powder, contact strength is reliable between the two thereby make, and adhesive force is improved.Therefore, the utility model has compared with prior art been eliminated film dancing, the film flying phenomenon of commutator, has prolonged the useful life of commutator.
Four, description of drawings
Fig. 1 is the structural representation of the overall plastic flat commutator of the utility model.
Fig. 2 is the B-B cut-away view of Fig. 1.
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 overall plastic flat commutator of the utility model, comprise commutator segment 1, phenolic moulding powder 2 (not having mica sheet between the commutator segment), commutator segment 1 is perpendicular with the axis (O axle) of this commutator, and the foot 3 of described commutator segment 1 has the claw type structure.The utility model forms overall plastic flat commutator body by copper coin through cold extrusion, makes the foot of commutator segment become the claw type structure through cold punching system, is pressed into phenolic moulding powder again and forms commutator.This commutator has compared with prior art been eliminated film dancing, the film flying phenomenon of commutator, has improved the quality of commutator, prolongs its useful life.Be specially adapted to pot motor.
In addition, the overall plastic flat commutator of the utility model not only is confined to illustrated overall plastic plane tank commutator, also comprises overall plastic planar-hook commutator certainly.
Claims (1)
1, a kind of overall plastic flat commutator comprises commutator segment (1), phenolic moulding powder (2), and commutator segment (1) is perpendicular with the axis of this commutator, and it is characterized in that: the foot (3) of described commutator segment (1) has the claw type structure.
