Abstract
The invention discloses a carbon brush used for an angle grinder. The carbon brush comprises a carbon body, a wire and a contact pin, wherein one end of the wire is buried in the carbon body, one end, close to the carbon body, of the contact pin is provided with a first wire clamping head and a second wire clamping head, the first wire clamping head and the second wire clamping head clamp the end, far from the carbon body, of the wire, and a groove is formed in one face, connected with the wire, of the carbon body. The double wire clamping heads are used for fixing the wire on the contact pin, so that the wire is not prone to falling off, the groove is further formed in the carbon body and can help the carbon brush to dissipate heat, and motor performance is ensured.
Description
Technical field
The present invention relates to a kind of carbon brush, especially a kind of carbon brush for electric angle grinder.
Background technology
Carbon brush is the device of transferring energy or signal between the standing part of motor or generator or other rotating machineries and rotating part, in the time of electric machine rotation, electric energy is flowed to coil by phase changer.Carbon brush, as a kind of sliding contact part, is widely used in many electric equipments.Traditional carbon brush is generally that pure carbon adds coagulating agent and makes, and external form is generally square, and volume varies, and on top, has wire to draw, and wire is connected with joint.General wire is welded on joint, the joint another side is fixed on the brush nest by spring, and the fixing pressure of spring is less, electric angle grinder using time body tremor amplitude is very large, and the wire of welding easily breaks away from from joint, affects machine operation, and when motor runs up, thereby carbon brush can produce heat by the high speed vibration, causes temperature to raise, and affects the machine operation performance.
Summary of the invention
The technical problem to be solved in the present invention is to provide the carbon brush that a kind of applicable electric angle grinder is used.
For solving the problems of the technologies described above, the technical scheme that the present invention takes is: a kind of electric angle grinder carbon brush, comprise carbon body, wire and contact pin, wire one end is embedded in the carbon body, it is characterized in that: contact pin is provided with the first clamp head and the second clamp head near an end of carbon body, the first clamp head and the second clamp head are clamped wire away from an end of carbon body, the carbon body is provided with a groove in the one side that connects wire.
As further improved technical scheme of the present invention, described wire is copper litz wire.
As further improved technical scheme of the present invention, described contact pin material therefor is copper.
The present invention is fixed on wire in contact pin with dual clipper joint, makes the wire difficult drop-off, also on the carbon body, is provided with groove, can help the carbon brush heat radiation, guarantees motor performance.
The accompanying drawing explanation
Accompanying drawing is structural representation of the present invention.
Embodiment
Referring to accompanying drawing, this electric angle grinder carbon brush, comprise carbon body 1, wire 2 and contact pin 3, wire 2 one ends are embedded in carbon body 1, one end of contact pin 3 close carbon bodies 1 is provided with the first clamp head 4 and the second clamp head 5, the first clamp heads 4 and the second clamp head 5 wire 2 is clamped away from an end of carbon body 1, and carbon body 1 is provided with a groove 6 in the one side that connects wire 2, wire 2 adopts copper litz wire, and contact pin 3 becomes for copper.This electric angle grinder is fixed on wire in contact pin with dual clipper joint with carbon brush, makes the wire difficult drop-off, also on the carbon body, is provided with groove, can help the carbon brush heat radiation, thereby guarantees motor performance.
