Embodiment 1

[0017] Such as figure 1 As shown, a new type of integral carbon brush holder includes a carbon brush holder main body 1 and an upper cover 2 made of insulating materials, which can be machined step by step or molded at one time, such as: injection molding, compression molding, etc. The upper cover 2 Set on the upper end surface of the carbon brush holder main body 1, the upper part of the carbon brush holder main body 1 is provided with a carbon brush fixing cavity 3, and the carbon brush is installed in the cavity between the carbon brush fixing cavity 3 and the upper cover 2, and on the carbon brush holder main body The fixed end 4 of 1 is drilled with a fixing screw hole 5, which can be rigidly fixed on the motor or other equipment directly with screws. On the side of the main body 1 of the carbon brush holder, there is a wire connection fixing screw hole 6, which can be connected to the fixing screw through the wire. The carbon brush is externally connected to the power li...

Embodiment 2

[0019] Such as figure 1 The difference between the shown structure and Example 1 is that the upper cover 2 is removed, the main body of the carbon brush holder is made of nylon material, and the mold is one-time injection molded. The carbon brush is inserted and installed from the front end in the air, and fixed in the wire connection fixing screw hole.

Embodiment 3

[0021] Such as figure 1 The middle structure is different from Example 2 in that it is the same except that the injection molding material is polytetrafluoroethylene.

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...
