Abstract
The utility model discloses a carbon brush structure and a motor. The carbon brush structure comprises a carbon rod, a carbon rod holding frame which is used for accommodating one end of the carbon rod, and an elastic component which is arranged inside the carbon rod holding frame and abuts against one end of the carbon rod. The carbon rod holding frame is made of thermosetting plastic. Cost can be saved and process can be saved by the carbon brush structure.
Description
Technical field
The utility model relates to machine field, particularly a kind of carbon brush structure and motor.
Background technology
Existing carbon brush structure comprises carbon-point, the carbon-point support of being made by common plastics that is fixed on the copper sheathing on carbon-point and contains copper sheathing.Existing structure needs first to put copper sheathing when mounted, then two parts of carbon-point support is being arranged on copper sheathing and is being fixed.Wherein copper sheathing is not yielding, and surfacing is smooth, has avoided carbon-point directly to contact and can produce larger friction with carbon-point retainer.But use copper sheathing to increase cost, and many when mounted installation steps, make calling program become loaded down with trivial details.
Summary of the invention
The purpose of this utility model is to provide a kind of carbon brush structure and motor, can be cost-saving, and saved operation.
Based on above-mentioned purpose, the utility model embodiment provides a kind of carbon brush structure, and described structure comprises:
Comprise carbon-point, for containing the carbon-point retainer of carbon-point one end and in carbon-point retainer and the elastomeric element inconsistent with described carbon-point one end; Wherein, carbon-point retainer is made by thermoset plastics.
Preferably, described carbon-point retainer is made by BMC BMC.
Preferably, described carbon-point retainer is by described thermoset plastics integrated injection molding.
Preferably, on the medial surface of carbon-point retainer, symmetry offers two grooves along its length.
Preferably, described carbon-point one end in described carbon-point retainer is directly connected with electric wire or is connected with sheet metal in turn and electric wire.
The utility model also provides a kind of motor, comprises stator and rotor, and described stator or rotor have above-mentioned carbon brush structure.
The beneficial effects of the utility model:
The utility model, by the carbon brush holder that uses thermoset plastics to make, makes, without copper sheathing is installed on carbon-point, compared to existing technology, to provide cost savings, and has saved a procedure.
Accompanying drawing explanation
Fig. 1 is the carbon brush structure schematic diagram in the utility model.
Embodiment
Fig. 1 shows the schematic diagram of a specific embodiment of the carbon brush structure that the utility model provides, as shown in Figure 1, the carbon brush structure in the present embodiment comprise carbon-point 11, for containing the carbon-point retainer 12 of carbon-point 11 one end and in carbon-point retainer 12 and the elastomeric element 13 inconsistent with described carbon-point 11 one end; Wherein, carbon-point retainer 12 is made by thermoset plastics.
In an embodiment of the present utility model, the inconsistent one end of carbon-point 11 and elastomeric element 13 is also connected with electric wire 14, carbon-point can directly connect this electric wire, also can be connected with electric wire by a sheet metal, this carbon-point can first be connected with one section of electric wire more specifically, then by this section of electric wire, be connected with sheet metal, finally by sheet metal, be connected with another electric wire again.
Because thermoset plastics have be heated or other conditions under can solidify or the characteristic of insoluble (melting), so it is not subject to the impact of external environment, even if not yielding under hot environment yet.And the carbon-point retainer surfacing that utilizes thermoset plastics to make is bright and clean, less with the friction of carbon-point.Therefore, in the utility model, carbon-point is directly inserted in carbon-point retainer without the fixing of copper sheathing.Prior art, has reduced the cost that copper sheathing is installed relatively, has reduced the operation that copper sheathing is installed simultaneously.
Carbon-point retainer in the utility model can be by thermoset plastics integrated injection molding.Also can combine and fixedly form by a plurality of thermoset plastics parts.As carbon-point retainer divides upper cover and lower cover two parts, its upper cover and under cover and all have outstanding flanging, on flanging, correspondence is offered fixing hole.First carbon-point is inserted when mounted in upper cover or lower cover, then, by another part laminating, by nut and fixing hole etc., be fixed.
In another embodiment, on the medial surface of carbon-point retainer, symmetry offers two grooves along its length, and carbon-point can insert in carbon-point retainer along groove.In the utility model preferred embodiment, for increasing thermal diffusivity, some louvres can be offered on carbon-point retainer, so that carbon-point dispels the heat in time.
In a preferred embodiment, above-mentioned carbon-point fender bracket can be by BMC(BMC) make.
Another embodiment of the utility model is also corresponding provides a kind of motor, and this motor comprises rotor and stator, and its rotor and/or stator can adopt the carbon brush structure having in above-described embodiment.
Above-described specific embodiment, the purpose of this utility model, technical scheme and beneficial effect are further described, institute it should be noted, the foregoing is only a specific embodiment of the present utility model, those skilled in the art can carry out various changes and modification and not depart from spirit and scope of the present utility model the utility model.Like this, if within of the present utility model these are revised and modification belongs to the scope of the utility model claim and equivalent technologies thereof, the utility model is also intended to comprise these changes and modification interior.
Claims (6)
