Abstract
The utility model discloses an electric grinder used carbon brush comprising a carbon body, a connecting wire, and a lug plate, one end of the connecting wire is buried in the carbon body, the other end of the connecting wire is connected with the lug plate, the carbon brush also comprises a pipe sleeve, and a portion of the connecting wire exposed outside is sleeved by the pipe sleeve. The electric grinder used carbon brush wraps a layer of insulating glass fibre sleeve pipe outside the wire, not only the carbon brush is insulated from conductive liquid so as to protect a motor, the sleeve pipe also can protect the connecting wire, and usage life of the carbon brush is prolonged.
Description
Technical field
The utility model relates to a kind of carbon brush, especially a kind of carbon brush for electrical grinding machine.
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 the rotating part, in the time of electric machine rotation, electric energy is flowed to coil by phase changer.Carbon brush is widely used in many electric equipments as a kind of sliding contact part.Traditional carbon brush generally is that pure carbon adds coagulating agent and makes, external form generally is square, volume varies, there is wire to draw on the top, wire exposes outside often, and the part wire of carbon brush need to pass conducting liquid in electrical grinding machine, but carbon brush can not directly contact with conducting liquid, otherwise easily motor is burnt out, so traditional carbon brush is not suitable in the electrical grinding machine.
The utility model content
The technical problems to be solved in the utility model provides the carbon brush that a kind of suitable electrical grinding machine is used.
For solving the problems of the technologies described above, the technical scheme that the utility model is taked is: a kind of electrical grinding machine carbon brush, comprise the carbon body, connect wire and lug plate, connecting wire one end is embedded in the carbon body, the other end is connected with lug plate, it is characterized in that: also comprise pipe box, pipe box firmly connects the exposed part outside of wire.
As the further improved technical scheme of the utility model, described sleeve pipe is glass fibre sleeve.
As the further improved technical scheme of the utility model, described carbon body is cuboid.
As the further improved technical scheme of the utility model, described connection wire is copper litz wire.
The utility model has wrapped up the glass fibre sleeve of one deck insulation at wire, not only can allow carbon brush and conducting liquid insulate to protect motor, and sleeve pipe can also be protected the connection wire, prolongs the useful life of carbon brush.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Embodiment 1
