Description

Anion brush subassembly

Technical Field

The utility model relates to a micro motor spare part technical field, in particular to anion brush subassembly.

Background

The DC motor has the advantages of good speed regulation and starting characteristics and large locked-rotor torque, so that the DC motor is widely applied to various driving devices and servo systems. However, the direct current motor has a brush and a commutator, which will not slide during the operation of the motor, and because the brush and the coil connector lug are alternately switched on and off, sparks and electromagnetic waves will be generated, which seriously affect the service life of the motor, and the generated electromagnetic waves will interfere with external electronic equipment. Brushless motors in the prior art use electronic commutation, with stationary coils and rotating magnetic poles. Although the brushless motor solves the problems of spark and electromagnetic interference generated by the brush motor, the brush motor is simple in structure, long in development time, mature in technology, high in response speed, large in starting torque, stable in operation and good in braking effect, and is still widely applied.

In the prior art, the generation of sparks and electromagnetic waves is generally reduced by changing the structure of the carbon brush and connecting a piezoresistor through a commutator. However, in the practical technology, the strong electromotive force generated in the alternate commutation process of the brush and the commutator is not utilized, and the spark is generated by the irregular ionized air.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing an anion brush subassembly, mainly used solve the brush and the commutator switching-over in-process does not have the forceful electric power electromotive force that rational utilization produced, does not guide, makes the spark that the ionized air produced concentrate on acting on brush and commutator, reduces the life's of motor problem.

The above technical problem of the present invention can be solved by the following technical solutions: comprises a carbon brush, the rear side of the carbon brush is connected with a wire, the other end of the wire is connected with a rear seat, the middle of the outer side of the rear seat is provided with a wiring terminal which is electrically connected with the lead, a spring is arranged between the carbon brush and the rear seat, the top of the carbon brush is electrically connected with a carbon fiber bundle, the carbon fiber bundle is wrapped on the insulating sleeve, the two sides of the rear seat are provided with buckles, the carbon brush is nested in the sleeve, the rear seat is clamped and fixed at the rear side of the sleeve through the buckle, the two sides of the sleeve are provided with mounting lugs, the mounting lug is provided with a through hole for mounting a screw, the top of the sleeve is provided with a square through groove, the rear side of the top of the sleeve, which is close to the square through groove, is provided with a wire clamp, one end of the carbon fiber bundle penetrates through the square through groove and then penetrates through the wire clamp, and the carbon fiber bundle is restrained and fixed by the wire clamp.

Preferably, the wire clamp is fixed to the top of the sleeve through a screw, the carbon fiber bundle is fixed to the top of the sleeve along with the wire clamp, and therefore the problem that the carbon fiber bundle falls off to cause the motor to be jammed in the operation process of the motor can be avoided.

The utility model has the advantages that: the instantaneous strong electric potential generated in the reversing process of the carbon brush and the commutator in the motor acts on the carbon fiber bundles to generate air negative ions, so that the air quality of the motor application scene is improved, the action area of electric sparks is dispersed, and the service life of the motor is prolonged.

Detailed Description

The technical solution of the present invention is further specifically described below by way of examples and with reference to the accompanying drawings.

Example (b): an anion brush assembly of this embodiment, as shown in fig. 1-5, includes a carbon brush 7, a wire 12 connected to a rear side of the carbon brush 7, a rear seat 8 connected to another end of the wire 12, a connecting terminal 9 disposed in the middle of an outer side of the rear seat 8, the connecting terminal 9 electrically connected to the wire 12, a spring 10 disposed between the carbon brush 7 and the rear seat 8, a carbon fiber bundle 6 electrically connected to a top of the carbon brush 7, the carbon fiber bundle 6 wrapped in an insulating sleeve 4, buckles 11 disposed on two sides of the rear seat 8, the carbon brush 7 nested in a sleeve 1, the rear seat 8 fixed to a rear side of the sleeve 1 by the buckles 11, mounting lugs 2 disposed on two sides of the sleeve 1, through holes 201 for mounting screws, a square through groove 3 disposed on a top of the sleeve 1, a wire clamp 5 disposed on a top of the sleeve 1 near the rear side of the square through groove 3, one end of the carbon fiber bundle 6, the carbon fiber bundle 6 is restrained and fixed by the wire clamp 5.

Wherein, fastener 5 passes through the screw fixation in 1 top of sleeve, is fixed at the top of sleeve 1 along with fastener 5, has also fixed carbon fiber bundle 6 at 1 top of sleeve to can avoid the motor at the operation in-process, carbon fiber bundle 6 takes place to drop, makes the problem of card machine appear in the motor.

In the embodiment, the end cover is fixedly arranged on the brush holder or the motor through the mounting lugs 2 on the two sides of the sleeve 1. After the sleeve 1 is installed, the carbon brush 7 is plugged into the sleeve 1 from the rear side of the sleeve 1, and when the carbon fiber bundle 6 can be seen from the square through groove 3 at the upper end of the sleeve 1, the carbon fiber bundle 6 is drawn out from the square through groove 3 at the upper end of the sleeve 1. The rear seat 8 is clamped and fixed on the rear side of the sleeve 1 through a buckle 11. Meanwhile, the carbon fiber bundles 6 are flatly placed and fixed to the top end of the sleeve 1 through the wire clamp 5, part of the carbon fiber bundles 6 are exposed out of the rear end of the insulating sleeve 4, the connection part of the carbon fiber bundles 6 and the carbon brush 7 is close to the action area of the carbon brush 7 and the commutator, and the exposed part of the carbon fiber bundles 6 is far away from the action area of the carbon brush 7 and the commutator. In this way, during the rotation of the carbon brush 7 and the commutator, a current commutation takes place, and when a strong potential is generated, the strong potential acts mainly at the contact of the carbon brush 7 and the commutator, i.e. near the beginning of the carbon fiber bundle 6. Thus, a strong electric potential will act on the carbon fiber bundle 6, the carbon fiber bundle 6 receives a high electric potential, and a strong electric field change, the carbon fiber bundle 6 will ionize the air, and air negative ions are decomposed. And the air negative ions are beneficial to air freshening, which is helpful to improve the air quality of the motor application scene, rather than only diffusing the taste of the lubricating oil.
