Embodiment Construction

[0011] Such as figure 1 As shown, an improved carbon brush for a motor of the present invention includes a carbon brush body 1, an internally threaded hole 3 is opened in the carbon brush body 1, and a bolt 4 is fixed in the internally threaded hole 3, and the head of the bolt 4 passes through a nut 5 Fixed on the carbon brush body 1, 10-20 strands of wire 2 are wound on the bolt 4, and one end of the wire 2 extending out of the carbon brush body is connected with the copper sheet 6, and the copper sheet 6 includes the wire tightening tube 7 and the wire tightening tube 7 integrally formed copper sheet head 8, one end of the wire 2 extending out of the carbon brush body 1 is wrapped in the wire tight tube 7 of the copper sheet 6.

[0012] One end of the wire 2 is wound tightly on the bolt 4, and the other end of the wire 2 is wrapped in the wire tight tube 7 of the copper sheet 6, so that it is not easy to fall off, and the service life of the carbon brush is long.

Abstract

The invention discloses a modified carbon brush for a motor. The modified carbon brush for the motor comprises a carbon brush body. An internal threaded hole is formed in the carbon brush. A bolt is fixed inside the internal threaded hole. The head portion of the bolt is fixed on the carbon body through a nut. Multiple wires are wound on the bolt. One ends, extending out of the carbon brush body, of the wires are connected with a copper sheet which comprises a wire packing tube and a copper sheet head, wherein the copper sheet head and the wire packing tube are integrally formed. The modified carbon brush for the motor has the advantages that one ends of the wires are wound on the bolt, winding is tight, the other ends of the wires are coated inside the wire packing tube of the copper sheet, dropping is not prone to happening, and service life of the carbon brush is long.

Description

technical field [0001] The invention relates to a carbon brush, in particular to an improved carbon brush for a motor. Background technique [0002] A carbon brush is a device that transmits energy or signals between the fixed part and the rotating part of the motor. It is generally made of pure carbon plus coagulant, and its shape is generally a square, which is stuck on a metal bracket. A carbon brush generally includes a carbon brush body, on which a wire leads out to connect with a copper sheet. During preparation, the wire is fused into the carbon brush body, and it is not easy to fall off under normal circumstances. However, when the motor is used for vibration, the wire will be detached from the carbon brush body, making the carbon brush unusable, which is very wasteful. Therefore, it is necessary to provide a new technical solution to solve the above problems. Contents of the invention [0003] The object of the present invention is to provide an improved carbon ...
