Abstract
The utility model discloses a double-wire safety carbon brush for an automobile. The double-wire safety carbon brush comprises a carbon body, a left connecting wire, a right connecting wire and a joint, wherein a self-jump hole is formed in the carbon body; one end of the left connecting wire extends into the self-jump hole; the end part of the left connecting wire is contacted with sheet metal; the sheet metal is equal to the section of the self-jump hole; an insulating spring is arranged below the sheet metal; one end of the insulating spring is contacted with the bottom of the self-jump hole, and the other end of the insulating spring is pressed on the sheet metal; the self-jump hole above the sheet metal is compacted by copper powder; one end of the right connecting wire is embedded in the carbon body, and the other end of the right connecting wire is clamped with the other end of the left connecting wire by a clamping head on the joint; and a joint hole is formed on the joint. Two wires are arranged on the carbon body, so that current can be stably output, and the normal operation of an automobile engine is guaranteed; and moreover, the insulating spring is arranged below the connecting wire, and when the carbon body is worn to the edge of the spring, the spring pops up, so that the carbon brush is separated from a motor, and the motor stops working, therefore, the motor is prevented from being burnt.
Description
Technical field
The utility model relates to a kind of carbon brush, especially a kind of carbon brush that is used for automobile current generator.
Background technology
Carbon brush is the device that transmits energy or signal between standing part and the rotating part of motor or generator or other rotating machineries, when motor rotates, electric energy is flowed to coil through 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 processes, and external form generally is a square, and volume varies, and has lead to draw on the top, and lead is connected with joint.Draw a lead on the general carbon brush, and automobile current generator requires electric current steady, otherwise cause the damage of generator easily, but often rotating speed is higher when using, unit pressure is higher, and carbon brush output is not easy to stablize; In the course of the work, the carbon of carbon brush cognition constantly is worn, and when the carbon body may wear to a certain degree, the lead that bury the inside can expose out with motor and directly contact, and causes burn-down of electric motor.
The utility model content
The technical problem that the utility model will solve provides the automobile of the steady output current of a kind of ability and uses carbon brush.
For solving the problems of the technologies described above, the technical scheme that the utility model is taked is: a kind of automobile comprises that with two-conductor line safety carbon brush carbon body, a left side connect lead, right connection lead and contact pin; Be provided with in the carbon body from jumping the hole, a left side connects lead one end to be stretched into from jumping in the hole, and a left side connects wire termination and contacts with sheet metal; Sheet metal is with big from jumping cross section, hole etc.; There is insulated spring the sheet metal below, and insulated spring one end contacts with jumping the bottom, hole certainly, and the other end is pressed on the sheet metal; Certainly the jumping hole of sheet metal top is by the copper powder compacting; A right end that connects lead is embedded in the carbon body, and the other end is clipped together with the other end that a left side is connected lead by the clipper joint in the contact pin, also is provided with in the contact pin and connects the hole.
As the further improved technical scheme of the utility model, said carbon body is a cuboid.
As the further improved technical scheme of the utility model, said carbon body is provided with 4 chamferings, and 4 chamferings are separately positioned on four long limits of carbon body.
As the further improved technical scheme of the utility model, said connection lead is a copper litz wire.
As the further improved technical scheme of the utility model, said contact pin material therefor is a brass.
The utility model is provided with two leads on the carbon body, can let electric current steadily export, and guarantees that automobile engine runs well; Below connecting lead, be provided with insulated spring, when the carbon body may wear to the spring marginal position, spring promptly ejected, and carbon brush and motor are broken away from, the motor stall, thus the protection motor is not burnt.
