Abstract

The utility model discloses an electric brush assembly supporting device of a direct-current micromotor. The electric brush assembly supporting device comprises a rear rubber cover, two brush assemblies and two capacitor components, wherein the two brush assemblies are fixedly arranged on the rear rubber cover, and the capacitor components are respectively connected with the brush assemblies. Each brush assembly comprises a brush assembly terminal, a brush assembly fastener and a brush assembly elastic arm. The top of each brush assembly is provided with a hook. Each capacitor component is provided with two capacitor component pins, the hooks are pressed downwards to enable the capacitor component pins and the brush assemblies to be fixedly conducted after the capacitor component pins penetrate through the hooks of the brush assembly terminals. The capacitor components and the brush assembly terminals are fixed firmly, and electromagnetic interference on other devices in the surrounding environment due to the fact the capacitor components and the brush assemblies are in instable contact during running of the motor is avoided.

Description

A kind of brush group supporting arrangement of direct current micromotor

Technical field

The utility model relates to a kind of brush group supporting arrangement of direct current micromotor.

Background technology

Direct current micromotor is as testing by EMC, prior art normally connects the effect that electric capacity of brush group (connecing the positive and negative power supply terminal) welding reached EMC at direct current micromotor two, but have now capacitance component is adopted welding manner, general use flatiron is difficult for burn-oning when welding, but also cause the phenomenon of rosin joint or dry joint easily, it is unstable to cause electric capacity electronic building brick and brush winding to be touched, defective when this motor carries out the EMC test, make equipment or system that this motor is housed when operation, produce electromagnetic interference to the miscellaneous equipment in its surrounding environment.How to avoid because contacting the EMC inefficacy that instability causes, and this product just is being based on above-mentioned consideration, the brush group structure of motor being crossed the equipment capacitance component of EMC changes, designed a kind of difference employed EMC of mistake structure in the past, a kind of the electric capacity electronic building brick is placed on motor glue bonnet inside, and adopts the mode that presses to satisfy the needs that motor is crossed EMC.

Summary of the invention

The technical problems to be solved in the utility model provide a kind of capacitance component and brush assembly of electric fixed, and can avoid producing the brush group supporting arrangement of the direct current micromotor of electromagnetic interference.

For solving technique scheme, the utility model adopts following technical scheme:

A kind of brush group supporting arrangement of direct current micromotor, comprise the glue bonnet, and be fixedly installed on two brush groups on the glue bonnet, and the capacitance component that is connected with two brush groups respectively, described brush group comprises brush group terminal, brush group buckle position and brush group elastic arm, described brush group top has a crotch, and described capacitance component has two capacitance component pin, and described capacitance component was worn and pressed down crotch behind the crotch on the brush group terminal capacitance component pin fixedly is communicated with the brush group.

As optimized technical scheme, described brush group buckle position is fixedly connected with carbon brush, and described carbon brush is fixed on the brush group elastic arm by brush group buckle position, and by the elastic force effect of brush group elastic arm, carbon brush head and rotor assembly transducer face are slided and electrically contacted.

The beneficial effects of the utility model are:

By technique scheme, the utility model capacitance component and brush assembly of electric terminal are fixed, and motor can not touch because of capacitance component and brush winding and unstable miscellaneous equipment in its surrounding environment be produced electromagnetic interference in running.

Description of drawings

In order to be easy to explanation, the utility model is done to describe in detail by following specific embodiment and accompanying drawing.

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the structural representation of brush group of the present utility model.

Embodiment

See also illustrated in figures 1 and 2, the brush group supporting arrangement of a kind of direct current micromotor of the present utility model, comprise glue bonnet 100, and be fixedly installed on two brush groups 300 on the glue bonnet 100, and the capacitance component 200 that is connected with two brush groups 300 respectively, described brush group 300 comprises brush group terminal 310, brush group buckle position 340 and brush group elastic arm 330, described brush group 300 tops have a crotch 320, described capacitance component 200 has two capacitance component pin 210, and described capacitance component pin 210 passes and presses down crotch 320 behind the crotch 320 on the brush group terminal 310 capacitance component pin 210 fixedly is communicated with brush group 300.

Preferably, described brush group buckle position 340 is fixedly connected with carbon brush 400, described carbon brush 400 is fixed on the brush group elastic arm 330 by 340 of brush group buckles, and by the elastic force effect of brush group elastic arm 330, carbon brush 400 heads and rotor assembly transducer face are slided and electrically contacted.

The beneficial effects of the utility model are:

The above only is embodiment of the present utility model, but protection range of the present utility model is not limited thereto, and any variation or replacement of expecting without creative work all should be encompassed within the protection range of the present utility model.Therefore, protection range of the present utility model should be as the criterion with the protection range that claims were limited.
