Abstract
The utility model discloses a carbon brush for a compound type electric hammer. The carbon brush comprises a carbon brush head and a carbon brush holder, wherein the carbon brush head is connected with the carbon brush holder through a lead wire, a cylindrical lug boss is arranged on the carbon brush holder, a spring is sleeved outside the lead wire, one end of the spring is fixed at the bottom of the carbon brush head, the other end of the spring wraps the cylindrical lug boss, and a tin layer is plated outside the lead wire. The spring can compensate the abrasion of the contact surface of the carbon brush and deliver a part of heat to ensure that the heat of the carbon brush holder is diffused in time; and meanwhile, because the tin layer is plated outside the lead wire, the conductivity is increased.
Description
Technical field
The utility model relates to a kind of carbon brush, in particular for the carbon brush of electric hammer.
Background technology
Electric hammer is the device that transmits energy or signal between standing part and the rotating part of motor or generator or other rotating machineries with carbon brush; It generally is that pure carbon adds coagulating agent and processes; External form generally is a square, is stuck on the metallic support, has lead to draw on the top; Lead is generally copper litz wire, and conductance is low.In running up, the carbon brush conduction current, because and CONTACT WITH FRICTION between carbon brush holder and the electric hammer, make the surface that abrasion take place and produce heat that heat can't in time shed.
The utility model content
The technical problem that the utility model will solve provides and a kind ofly can increase conductance, and the electric hammer that prolongs carbon brush useful life is used carbon brush.
For addressing the above problem, the technical scheme that the utility model is taked is: a kind of compound electric hammer is used carbon brush, comprises carbon brush head and carbon brush holder; The carbon brush head is connected with carbon brush holder through lead; Carbon brush holder is provided with cylindrical boss, and lead is with spring outward, and an end of spring is fixed on carbon brush head bottom; The other end parcel cylindrical boss of spring, lead serving tin.As a kind of improvement of the utility model, the carbon brush head is the copper sheet metal.
Adopt said structure, spring is as an elastic force apparatus, and the spring handle carbon brush is pressed in the rotating shaft; Promoting carbon brush and moving and keep this carbon brush to contact with the close of this rotor, preventing the change of carbon brush position, this outer spring can compensate the abrasion of the contact surface of carbon brush; Transmit a part of heat, the heat of carbon brush holder is in time distributed, prolong carbon brush useful life; Simultaneously zinc-plated outside lead, conductance increases.
Description of drawings
Accompanying drawing 1 is the principal section figure of the utility model.
Embodiment
Below in conjunction with embodiment and accompanying drawing the utility model is further specified.This compound electric hammer is used carbon brush, comprises carbon brush head 1 and carbon brush holder 2, and carbon brush head 1 is connected with carbon brush holder 2 through lead 3; Carbon brush holder 2 is provided with cylindrical boss 5; Be with spring 4 outside the lead 3, an end of spring 4 is fixed on carbon brush head 1 bottom, the other end parcel cylindrical boss 5 of spring 4; Lead 3 serving tin 6, carbon brush head 1 is the copper sheet metal.Spring can compensate the abrasion of the contact surface of carbon brush, transmits a part of heat, and the heat of carbon brush holder is in time distributed, and prolongs carbon brush useful life, and is simultaneously zinc-plated lead outside, the conductance increase.
Claims (2)
