Abstract
The utility model discloses a carbon brush for a dust collector, which comprises two carbon brush units. Two copper wires are led from the two carbon brush units and are stranded into a copper wire strand through a stranding pipe, the tail end of the copper wire strand is welded on a copper piece which is provided with a mounting hole, and an insulation protective jacket is sleeved on the copper wire strand. The carbon brush for the dust collector has the advantages that the copper wire strand and the carbon brush units are not easy to crack, the copper wire strand is prevented from falling off the carbon brush units by an anti-falling jacket, and accordingly the service life of the carbon brush is prolonged.
Description
Technical field
The utility model relates to carbon brush, relates in particular to dust catcher and uses carbon brush.
Background technology
Carbon brush is the device that transmits energy or signal between household electrical appliance standing part and the rotating part, and it generally is that pure carbon adds coagulating agent and processes, and external form generally is a square, is stuck on the metallic support.General carbon brush surface smoother, carbon brush is stuck on the metallic support.Carbon brush is general to connect a lead, and this wire end connects copper sheet, though this structure is simple, because the vibrations during household electric appliance operation, causes between lead and the carbon brush easily, ruptures between lead and the copper sheet, causes the electrical equipment break-off.Therefore, need provide a kind of new technical scheme to solve the problems referred to above.
The utility model content
The purpose of the utility model provides the dust catcher of long service life and uses carbon brush.
The technical scheme that the utility model adopts is:
Dust catcher is used carbon brush; Comprise the carbon brush body, said carbon brush body comprises two, leads to a copper cash on each carbon brush body; Two copper cash are merged into one copper cash through closing beam tube; Said copper cash end is welded on the copper sheet, has installing hole on the said copper sheet, is with insulation protective jacket on the said copper cash.
Be fixed with anti-press-offing on the copper cash lead surface of said carbon brush body.
A said end caliber that closes beam tube is greater than other end caliber.
The beneficial effect of the utility model: the carbon brush body comprises two; Lead to a copper cash on each carbon brush body; Two copper cash are merged into one copper cash through closing beam tube; This structure has guaranteed between copper cash and the carbon brush body not easy fracture, and anti-press-offing prevents that copper cash from coming off from the carbon brush body, makes the longer service life of carbon brush.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Wherein: 1, carbon brush body, 2, copper cash, 3, close beam tube, 4, copper sheet, 5, installing hole, 6, insulation protective jacket, 7, the copper cash lead surface, 8, anti-press-offing.
Embodiment
As shown in Figure 1, the dust catcher of the utility model is used carbon brush, comprises carbon brush body 1; Carbon brush body 1 comprises two, leads to 2, two copper cash 2 of a copper cash on each carbon brush body 1 and merges into one copper cash 2 through closing beam tube 3; An end caliber that closes beam tube 3 is greater than other end caliber; Copper cash 2 ends are welded on the copper sheet 4, have installing hole 5 on the copper sheet 4, are with insulation protective jacket 6 on the copper cash 2; Be fixed with on the copper cash lead surface 7 of carbon brush body 1 and anti-press-off 8, anti-press-offing 8 prevents that copper cash 2 from coming off from carbon brush body 1.
Carbon brush body 1 comprises two, leads to 2, two copper cash 2 of a copper cash on each carbon brush body 1 and merges into one copper cash 2 through closing beam tube 3, and this structure has guaranteed between copper cash 2 and the carbon brush body 1 not easy fracture, makes the longer service life of carbon brush.
