Abstract
The utility model discloses a carbon brush for small household electrical appliances. The carbon brush comprises a carbon brush body; a conducting wire is led out from the interior of the carbon brush body; the tail end of the conducting wire is welded onto a copper sheet; the copper sheet comprises a copper sheet cap and copper sheet bars; the copper sheet bars are formed at two ends of the copper sheet cap in a bending manner; a spring is sleeved on the periphery of the conducting wire; one end of the spring is welded onto the carbon brush body; and the other end of the spring is welded onto the copper sheet. The carbon brush for the small household electrical appliances has the advantages that: in order to prevent the conducting wire from falling from the copper sheet due to a relatively-large shaking force generated by mechanical rotation, the tail end of the conducting wire is welded onto the copper sheet, and the connection between the conducting wire and the copper sheet is much firmer compared with that the conducting wire is tightly pressed by the copper sheet, so that the service life of the carbon brush is prolonged.
Description
Technical field
The utility model relates to carbon brush, relates in particular to small household appliances and uses carbon brush.
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, 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.Some carbon brush structure is simple, and lead is pressed by the copper sheet chieftain, because mechanical rotation produces bigger shaking force, comes off easily, and shorten the useful life of carbon brush.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 small household appliances of a kind of difficult drop-off, long service life and uses carbon brush.
The technical scheme that the utility model adopts is:
Small household appliances are used carbon brush, comprise the carbon brush body, lead to lead in the said carbon brush body; Said wire end is welded on the copper sheet; Said copper sheet comprises copper sheet cap and copper sheet bar, and said copper sheet cap two ends are bent with the copper sheet bar, and said lead periphery is with spring; Said spring one end is welded on the carbon brush body, and the said spring other end is welded on the copper sheet.
Said lead is a copper core flexible cord.
Said carbon brush body be shaped as cuboid.
The beneficial effect of the utility model: produce bigger shaking force for overcoming mechanical rotation; Cause lead and copper sheet to come off, the utility model adopts wire end to be welded on the copper sheet, and the lead of comparing is pressed by the copper sheet chieftain; Want firm many, increased the useful life of carbon brush.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Wherein: 1, carbon brush body, 2, lead, 3, copper sheet, 4, the copper sheet cap, 5, the copper sheet bar, 6, spring.
Embodiment
As shown in Figure 1, the small household appliances of the utility model are used carbon brush, comprise the carbon brush body 1 of rectangular shape; Lead to lead 2 in the carbon brush body 1, lead 2 is a copper core flexible cord, and lead 2 ends are welded on the copper sheet 3; Copper sheet 3 comprises copper sheet cap 4 and copper sheet bar 5, and copper sheet cap 4 two ends are bent with copper sheet bar 5, and lead 2 peripheries are with spring 6; Spring 6 one ends are welded on the carbon brush body 1, and spring 6 other ends are welded on the copper sheet 3.
Produce bigger shaking force for overcoming mechanical rotation, cause lead and copper sheet 3 to come off, the utility model adopts lead 2 ends to be welded on the copper sheet 3, and the lead 2 of comparing is pressed by the copper sheet chieftain, be firm many, increased useful life of carbon brush.
