Abstract
The utility model relates to the automobile air conditioner motor technology field, and specifically relates to an anti-interference circuit device for an automobile air conditioner motor. The anti-interference circuit device comprises a commutator, a positive brush and a negative brush; the positive brush and the negative brush are disposed outside the commutator, one end of the positive brush is serially connected with an inductance coil L1, and one end of the negative brush is serially connected with an inductance coil L2; a capacitor C1 is in parallel connection between the inductor L1 and the inductor L2; and one terminal of the capacitor C1 is in parallel connection with a capacitor C2, and the other terminal of the capacitor C2 is connected to a housing. High-frequency current can be effectively filtered by parallelly connecting the capacitors in the circuit, so that anti-interference effect is achieved, and the anti-interference circuit device is simple in structure and convenient in circuit connection.
Description
Technical field
The utility model relates to automobile air conditioner motor branch art field, is specifically related to a kind of for the anti-clutter circuit device on automobile air conditioner motor.
Background technology
The utility model relates to automobile air conditioner motor branch art field, is specifically related to a kind of for the anti-clutter circuit device on automobile air conditioner motor.
Summary of the invention
At present, along with people's living standard improves constantly, automobile has also become the requisite a kind of instrument of a lot of families and unit trip, meanwhile, and the part that air conditioning for automobiles must not lack in automobile especially.Air conditioning for automobiles can be placed unlike the domestic air conditioning of common use in a more fixing environment; due to automobile often in the process of moving; usually can be subject to vibrations in various degree and the interference of external environment, the air conditioner motor-permanent magnet DC motor in automobile when work usually because brush contacts and realizes commutation function with commutator.Meanwhile, produce electric spark and high-frequency current between commutator and brush, these high-frequency currents have certain interference effect to the instrument and equipment in automobile, and traffic safety is existed to hidden danger.
Summary of the invention
The utility model is in order to overcome the problems referred to above, provides a kind of simple in structure, circuit side connector just and has been specifically designed to the anti-clutter circuit device on automobile air conditioner motor.
In order to achieve the above object, the utility model provides a kind of automobile air conditioner motor anti-clutter circuit device, comprise commutator, positive brush and negative pole brush, described commutator is provided with positive brush and negative pole brush outward, and described positive brush and negative pole brush two ends are in series with respectively inductance coil L1 and inductance coil L2; Between described inductance L 1 and inductance L 2, be also parallel with capacitor C 1; Described capacitor C 1 one end is parallel with capacitor C 2 and capacitor C 2 other ends are connected on shell (ground connection).Can effectively filter out like this high-frequency current, thereby reach jamming-proof effect.
The utility model beneficial effect is: by shunt capacitance in circuit, can effectively filter out high-frequency current, thereby reach jamming-proof effect, and also simple in structure, circuit side connector is just.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of automobile air conditioner motor anti-clutter circuit device described in the utility model.
In figure: 1-commutator, 2-positive brush, 3-negative pole brush.
Embodiment
As shown in Figure 1, it is a kind of automobile air conditioner motor anti-clutter circuit device, comprise commutator 1, positive brush 2 and negative pole brush 3, outer positive brush 2 and the negative pole brush 3 of being provided with of described commutator 1, meanwhile, positive brush 2 and negative pole brush 3 two ends are in series with respectively inductance coil L1 and inductance coil L2; And be also parallel with capacitor C 1 between inductance L 1 and inductance L 2; The other end that described capacitor C 1 one end is parallel with capacitor C 2 and capacitor C 2 is connected on shell (ground connection).Can effectively filter out like this high-frequency current, thereby reach jamming-proof effect.
