Lead connection structure of brush assembly for motor

Abstract

Connection structure of leading wire is composed of following parts: bracket fixed on one side of housing cap of motor; bracket of electrical brush passing through housing cap and connected to one side of it; leading wire for connecting electrical brush to one side of bracket of electrical brush, and electrifying them; coil spring for elastic supporting one side of brush to make frictional contact between brush and collector. There is a connection structure in one end of leading wire. Thus, one end of leading wire cab fixed on the electrical brush as well as leading wire can be plugged into the structure and pulled out from the structure. The structure can simplifies connecting procedure so as to raise production efficiency.

Description

technical field [0001] This invention relates to vacuum cleaners, and more particularly to brush assemblies for electric motors. Background technique [0002] Hereinafter, a conventional motor for a conventional vacuum cleaner will be described with reference to the accompanying drawings. [0003] Such as figure 1 As shown, the existing vacuum cleaner motor (100) is made of the following components: a machine cover (Housing, 110), which is a cylindrical shape with one side open; On the inner surface of the cover (110); the rotor (140), which is inserted into the inside of the stator (130) and can rotate; the rotating shaft (141), which runs through the center of the rotor (140) and is connected with it, can be connected with the above-mentioned rotor ( 140) move together; the commutator (150), which is fixed in the axial direction of the above-mentioned rotating shaft (141) in a press-fit manner; the impeller (170), which is fixed on the direction of the rotating shaft and...

AI Technical Summary

Problems solved by technology

[0009] However, in the prior art, the lead wire (165) needs to be connected to the inner surface of the opening and closing plate (162a) of the brush holder (162) by spot welding, so there will be complicated processing operations, increased processing costs, and high production costs. Efficiency reduction and other issues

[0010] In addition, the long-term use of the motor will wear the brush (163), so it needs to be replaced

When replacing the brush (163), it is necessary to remove the lead wire (165) welded on the opening and closing plate (162a) of the brush bracket (162), and then re-weld the lead wire (165) of the new brush (163) Therefore, there is a problem of inconvenience in maintenance work
