Abstract
The utility model discloses an electrical brush, comprising a brush body, wherein a lead packing hole is arranged at the upper part of the brush body; the electrical brush further comprises a copper lead; and one end of the copper lead is connected with a conductive connecting piece. The electrical brush is characterized in that the other end of the copper lead is connected with the brush body through carbon powder packed in the packing hole. In the electrical brush, the copper lead is fixed in the electrical brush body through the carbon powder in the lead packing hole. The carbon powder material for packing ensures that the copper lead is connected and fastened with the brush body. The carbon powder has stable electrical conductivity and thermal conductivity; and even if the temperature of the electrical brush is raised in the use process, the connecting resistance and the pulling-out force of the lead of the electrical brush cannot be influenced and the motor can be normally used.
Description
Technical field
The utility model relates to a kind of brush.
Background technology
The loading demand of locomotive traction motor and mining traction electric machine is increasing, and current of electric increases thereupon, and the current density in the brush use is also increasing, and brush brush body temperature raises along with the increase of current density.Made the brush of padding with the fixed copper lead with copper powder in the past, oxidation may the Yin Wendu rising take place in the filling copper powder of its use, and therefore copper powder resistance increase thereupon, and the connection resistance of brush also becomes increasing; Therefore cause the brush body temperature to raise.And brush constantly vibrations in use, copper conductor is easier coming off therefore, causes serious motor use accident.
The utility model content
The purpose of this utility model is in order to overcome deficiency of the prior art, a kind of brush of copper conductor difficult drop-off to be provided.
For realizing above purpose, the utility model is achieved through the following technical solutions:
A kind of brush comprises brush body, and brush body top is provided with the lead fill-up hole; Also include copper conductor, copper conductor one end is connected with conductive tabs, it is characterized in that, the copper conductor other end is connected with brush body by the carbon dust of filling in the lead fill-up hole.
Wherein, described brush body is provided with pressure pad, and described copper conductor passes pressure pad, and the copper conductor other end is connected with brush body by the carbon dust of filling in the lead fill-up hole.
Pressure pad is that insulating material is made.
Wherein, described pressure pad is provided with crash roll.
Wherein, the material of described brush body is the graphitization matrix of electrographite matrix or impregnating resin.
Wherein, described copper conductor is provided with insulating case.
Wherein, pressure pad can be cuboid, square or cylinder, also can be other shape that needs.Preferably, described brush body bottom vertical section is a triangle.
Wherein, described brush body is two compositions, and the cross section is formed at two brush body tops is leg-of-mutton groove, and the pressure pad lower shape matches with triangular groove.
Wherein, described conductive tabs is pincerlike.
Wherein, described copper conductor is four, and four copper conductors are connected with conductive tabs jointly.
Brush in the utility model, copper conductor are to be fixed in the brush brush body by the carbon dust in the lead fill-up hole.It is fastening that this filling makes that with carbon powder material copper conductor is connected with brush body.The conductivity of carbon dust and thermal conductivity are all more stable, even in use the brush temperature raises, also can not influence it and connect resistance and conductor pull-out force, guarantee the normal use of motor.
Description of drawings

Fig. 2 is a left TV structure schematic diagram of the present utility model;
Fig. 3 is the brush vertical view in the utility model, not shown conductive tabs and copper conductor.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in detail:
As Fig. 1, Fig. 2, shown in Figure 3, a kind of brush comprises brush body 1, and brush body 1 is that two (12,13) are formed, and vertical section is formed at two brush bodies (12,13) top is leg-of-mutton groove (not marking among the figure).
Pressure pad 2 is provided with crash roll 3.Crash roll 3 can play antihunt action, can prevent in the use because of vibrations but copper conductor and brush body break away from.
Also include 4, four copper conductor 4 one ends of four copper conductors and be connected with a conductive tabs 5 jointly, conductive tabs 5 is pincerlike.
Four copper conductors 4 pass the through hole 22 of pressure pad 2 and closely are connected with pressure pad 2, and four copper conductor 4 other ends are plugged in respectively in the lead fill-up hole 11.Filling has the carbon dust (not shown) in the lead fill-up hole 11, and carbon dust is fastenedly connected copper conductor 11 and brush body 1.
Copper conductor 4 is provided with insulating case 6.
The material of brush body 1 is the graphitization matrix of electrographite matrix or impregnating resin.
Embodiment in the utility model only is used for the utility model is described, and does not constitute the restriction to the claim scope, and other substituting of being equal in fact that those skilled in that art can expect are all in the utility model protection range.
