Abstract
The invention discloses a carbon brush of a motor. The carbon brush of the motor comprises a carbon brush body, the top end of the carbon brush body is in a trapezoid shape, two side faces of the top end are respectively provided with a metal sheet which is provided with a round hole, two conducting wires are led out from the two side faces of the top end of the carbon brush body respectively and penetrate through the round holes in the metal sheets, the tail ends of the conducting wires are combined and connected with a copper sheet, and an elliptical hole is formed in the middle of the copper sheet. The carbon brush of the motor has the advantages that the structure is simple; the two lead-out conducting wires are fixed on the carbon brush body through the metal sheets and are not prone to falling off, service life is long, service life of use equipment is prolonged, and production cost of an enterprise is lowered.
Description
Technical field
The present invention relates to a kind of carbon brush for electric 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 rotating part, it is generally that pure carbon adds coagulating agent and makes, external form is generally square, be stuck on metallic support, there is spring handle the inside it is pressed in rotating shaft, such as after oil drilling completes, need to detect, will put instrument from pit shaft and go down, by carbon brush, signal be delivered to ground instrument from rotating part (cable drum of outsourcing steel wire).The appearance of carbon brush a little, as the rubber bar of wiping pencil, has wire to draw on top.Volume varies.Carbon brush, as a kind of sliding contact part, is widely used in many electric equipments.Product material mainly contains electrographite, soaks fat graphite, metal (cupric, silver) graphite.
Summary of the invention
The object of the invention is to provide a kind of carbon brush of simple in structure, long service life.
The solution of the present invention is as follows: a kind of carbon brush for electric machine, comprise carbon brush body, described carbon brush body top is trapezoidal, and two sides, described top are respectively arranged with sheet metal, described sheet metal is provided with circular hole, and circular hole sheet metal is drawn and passed to wire from two sides, carbon brush body top.
Described wire is wrapped with electro-insulating rubber overcoat.
Beneficial effect of the present invention: simple in structure; Draw wire by two and be fixed on carbon brush body by sheet metal, difficult drop-off, long service life, has improved the life cycle that uses equipment, reduces enterprise's production cost.
