Abstract

Disclosed is a carbon-brush seat including a support frame, two carbon brushes and two coil springs, wherein two ends of the support frame are each provided with a carbon-brush accommodating groove and the carbon brushes are movably accommodated in the accommodating grooves. The coil springs are provided with coil central positions which are arranged in a range of parallel extension directions of top faces and bottom faces of the carbon-brush accommodating grooves. The coil springs apply acting forces which are parallel to moving directions of the carbon brushes to the carbon brushes so that in a moving process, both of the carbon brushes can bear stable and uniform jacking forces. Therefore, an effect that the carbon brushes are in excellent contact with a surface of a collecting ring is ensured.

Description

Technical field

[0001] The present invention relates to a slip ring device, and more specifically refers to a carbon brush holder that can improve the effect of electrical conduction. Background technique

[0002] figure 1 Shown is a known carbon brush holder 1, which is composed of a supporting frame 2, two carbon brushes 3, two wires 4, and two torsion springs 5. Wherein, each side of the support frame 2 has a pocket 2a, and each pocket 2a has a long cross-sectional groove 2b; the two carbon brushes 3 are respectively placed in each pocket 2a; the two wires 4 are covered with insulation One end 4a of the wire 4 is fixed to the top of the support frame 2, and the other end 4b is fixed to the upper half of the carbon brush 3; the two torsion springs 5 ​​are respectively wound on a fixing pin 6 provided on the support frame 2. And its pushing force promotes the carbon brush 3 to move downward, thereby ensuring that the bottom end of the carbon brush 3 can maintain contact with th...
