Embodiment Construction
[0011] like figure 1 As shown, the carbon brush for small household appliances of the present invention includes a carbon brush body 1 in the shape of a rectangular parallelepiped, and a lead wire 2 is drawn out from the carbon brush body 1. The sheet 3 includes a copper sheet cap 4 and a copper sheet strip 5. The copper sheet cap 4 is bent with a copper sheet strip 5 at both ends, and a spring 6 is sleeved on the periphery of the wire 2. Solder on copper sheet 3.
[0012] In order to overcome the large vibration force generated by the mechanical rotation, causing the wire and the copper sheet 3 to fall off, the present invention adopts the end of the wire 2 to be welded on the copper sheet 3. Compared with the wire 2 being pressed by the copper sheet head, it is much firmer and increases the The service life of carbon brushes.

The invention discloses a carbon brush for a small household appliance. The carbon brush comprises a carbon brush body from which a wire is led. The tail end of the wire is welded on a copper sheet. The copper sheet comprises a copper sheet cap and copper sheet strips. The copper sheet strips are bent at the two ends of the copper sheet cap. A spring is sleeved on the periphery of the wire. One end of the spring is welded on the carbon brush body, and the other end of the spring is welded on the copper sheet. The carbon brush has the advantages that in order to solve the problem that the wire and the copper sheet are separated by strong shaking force generated by mechanical rotation, the tail end of the wire is welded on the copper sheet, and compared with a carbon brush of which the wire is tightly pressed by a head of the copper sheet, the carbon brush is much firmer, so that the service life of the carbon brush is prolonged.
Description
technical field [0001] The present invention relates to carbon brushes, in particular to carbon brushes for small household appliances. Background technique [0002] A carbon brush is a device that transmits energy or signals between the stationary part and the rotating part of a motor or generator or other rotating machinery. Some carbon brushes are simple in structure, and the wires are pressed by the copper head. Due to the large vibration force generated by the mechanical rotation, it is easy to fall off, and the service life of the carbon brush is shortened. Therefore, it is necessary to provide a new technical solution to solve the above problems. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a carbon brush for small household appliances that is not easy to fall off and has a long service life. [0004] The technical scheme adopted in the present invention is: [0005] A carbon brush for small household appliances, including ...
