The wire and the carbon brush body are integrally pressed, the connection resistance between the carbon brush body and the wire is low, and the connection resistance is unchanged in the use process of the electric brush; the overall voltage drop of the wind power carbon brush is low; the pulling force of the lead and the carbon brush body can be effectively improved.
The diameter of the lead is 1/4-1/2 of the thickness of the carbon brush body, and the distance between the axis of the lead and the front and back surfaces of the carbon brush body is equal.
In the pressing process, the lead is kept at the middle position of the front surface and the rear surface of the carbon brush body, so that the pulling force of the lead and the carbon brush body is increased.
The length of the lead wire inside the carbon brush body is 1/5-1/3 of the height of the carbon brush body.
The wire and the carbon brush body are tightly connected, so that the connection resistance can be reduced, and the service life of the product is greatly prolonged.
The upper end of carbon brush body is equipped with the stationary blade, and the stationary blade includes vertical portion and horizontal part, and the lower extreme of vertical portion links to each other with carbon brush body up end is perpendicular, and the one end of horizontal part links to each other with the upper end of vertical portion is perpendicular.
The upper end of the carbon brush body is also provided with a through hole parallel to the upper end face of the carbon brush body, the conducting wire is positioned at one side of the carbon brush body, and the through hole is positioned at the other side of the carbon brush body.
The upper end face of the carbon brush body between the through hole and the wire is provided with an arc-shaped groove, and the axis of the arc-shaped groove is parallel to the upper end face of the carbon brush body.
The utility model has the advantages and positive effects that: by adopting the technical scheme, the connection resistance between the carbon brush body and the lead is low, and the connection resistance is unchanged in the using process of the electric brush; the overall voltage drop of the wind power carbon brush is low; the pulling force of the lead and the carbon brush body is effectively improved; the service life of the wind power carbon brush is prolonged, and the reliability of the wind power carbon brush in the using process is improved.
