Novel overall carbon brush holder

Abstract

A novel overall carbon brush holder relates to the technical field of electric fittings. The novel overall carbon brush holder comprises a carbon brush holder main body integrally made of an insulation material and an upper cover, and can adopt mechanical gradual processing or mold one-time molding, such as injection molding, compression molding and the like. The upper cover is disposed on the upper end face of the carbon brush holder main body, the upper part of the carbon brush holder main body is provided with carbon brush fixing cavities, carbon brushes are installed in a hollow cavity between the carbon brush fixing cavities and the upper cover, a fixing end of the carbon brush holder main body is provided with fixing screw holes and can be directly and rigidly fixed on a motor or other instruments through screws, a side face of the carbon brush holder main body is provided with wires to be connected with the fixing screw holes, the screws are connected and fixed through the wires, and then a carbon brush external power line can be connected. The carbon brush holder structure is simplified, the number of parts is reduced, production cost is reduced, and post maintenance and replacement in use are convenient.

Description

technical field

[0001] The invention relates to the technical field of electrical accessories, in particular to a novel integral carbon brush holder. Background technique

[0002] In DC motors, carbon brush holders need to be installed for the conduction of the rotor. The current carbon brush holders are complex in structure and bulky, and most of them are made of metal, so there is a risk of electric leakage. In some special mechanical fields, such as rotating the electric heating roller to conduct electricity, it is necessary not only to have a good conductivity effect, but also to withstand a certain temperature. Under the premise of meeting the use requirements, try to reduce the volume of the machine and the materials used for processing, and reduce the number of parts and components. Excessive production, processing and maintenance during use. At present, the brush holder is used, the structure is too complicated, it is prone to failure, and it is inconvenient to main...
