Abstract
The utility model discloses a novel carbon brush for a micromotor. The carbon brush of the utility model is composed of a brush body, a brush plait, a spring and a brush cap, wherein the spring is designed by adopting a long and thin spindle shape and is sheathed on the brush plait, and the whole carbon brush is arranged in a brush holder. Because the spring which provides pressure for the brush body is designed into the long and thin spindle shape, the pressure is uniform, and the spring can not be bent in the brush holder. The carbon brush is basically not contacted with the brush holder when the motor runs, and then the noise phenomenon brought from the running of the motor is avoided, and the motor can run steadier.
Description
Technical field
The utility model belongs to field of motor manufacturing, relates to a kind of electrical micro-machine parts, specifically is a kind of novel carbon brush that is used for electrical micro-machine.
Background technology
At present in the electrical micro-machine industry in order to reduce carbon brush and the brush holder contact-making surface between cooperating, on four limits of brush holder, add a spot of circular arc, the mating surface between carbon brush and the brush holder mainly is that four jiaos of the non-arc surface of brush holder cooperate with carbon brush four edged surfaces.Pressure on the brush body is that the spring by the brush body rear portion provides, and in numerous designs, spring is straight tubular design mostly, the external diameter of spring is can freely stretching in brush holder, and guarantee brush body stressed be standard.If the spring external diameter is excessive in this kind design, brush body can only be four jiaos and contact with spring end face, often causes the brush body discontinuity, increases motor noise; If external diameter is too small, can guarantee that the whole end face of brush body contacts with spring end face, but spring but can be in brush holder free bend, also tend to make the carbon brush discontinuity, increase motor noise.
Summary of the invention
The utility model aims to provide a kind of novel carbon brush that is used for electrical micro-machine, in order to solve the problems of the technologies described above.
The technical solution of the utility model must be such: this carbon brush comprises brush holder and the brush body that sets within it, be nested with a spring on the brush pigtail of described brush body rear end, described spring adopts elongated spindle design, the diameter at spring middle part and the diameter ratio of end are 1.2-1.5, the one end is fixed on the rear end of brush body, the brush cap phase configuration of the other end and carbon brush.
Adopted technique scheme, the beneficial effect that brings to the utility model is: be designed to elongated spindle with the spring of brush body phase configuration, and can be so that whole end face of brush body and spring end face even contact.When being under pressure, the spindle spring can provide uniform pressure to brush body, and can be in brush holder crooked, thereby the noise phenomenon the during motor rotation of having avoided bringing thus makes the motor operation more steady.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the utility model carbon brush;
Accompanying drawing 2 is a kind of structural representations of the utility model brush holder spring;
Accompanying drawing 3 is a kind of plan structure schematic diagrames of the utility model carbon brush brush holder;
Accompanying drawing 4 is a kind of sectional structure schematic diagrames of the utility model carbon brush brush holder.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: referring to Fig. 1, carbon brush of the present utility model is made of brush body 4, brush pigtail 3, spring 2 and brush cap 1, and its medi-spring 2 is nested with on brush pigtail 3, and the one end is fixed on the rear end of brush body 4, brush cap 1 phase configuration of the other end and carbon brush.Referring to Fig. 2, spring adopts elongated spindle design, and two ends are slightly thin than the middle part, and the diameter at its middle part and the diameter ratio of end are 1.2-1.5.Referring to Fig. 3 and Fig. 4, whole carbon brush is arranged in the brush holder 5, owing to provide the spring of pressure to be designed to elongated spindle to brush body, make pressure evenly and also spring can be crooked in brush holder, carbon brush does not contact basically with brush holder during the motor operation, thereby the noise phenomenon the during motor rotation of having avoided bringing thus makes the motor operation more steady.
At last, should be pointed out that above embodiment only is the more representational example of the utility model.Obviously, the utility model is not limited to the foregoing description, and many distortion can also be arranged.Every foundation technical spirit of the present utility model all should be thought to belong to protection range of the present utility model to any simple modification, equivalent variations and modification that above embodiment did.
