Description
Technical field
It the utility model is related to a kind of carbon brush structure of motor, and in particular to a kind of insulated carbon brush.
Background technology
Surge current is power on moment, flows into the peak point current of power-supply device.Because input filter capacitor fills rapidly
Electricity, so the peak point current is far longer than stable state input current.Although surge current can't be utilized well at present,
Exploitation to its safe and reasonable Application way has begun to.The design of existing carbon brush is to need to avoid peak point current from occurring, and is prevented
Electric spark wears to caused by carbon brush, thus can not be using surge current come work；And conduction time is grown in existing carbon brush, to carbon
The serious wear of brush, and volume size is required.
The content of the invention
The utility model is directed to the above-mentioned deficiency of prior art, there is provided one kind can utilize surge current and shorten and lead
The insulated carbon brush of electric time.
In order to solve the above technical problems, the utility model employs following technical proposal：
Provide a kind of insulated carbon brush, it is characterised in that including conductive coating and insulated brush, insulated brush is in cuboid knot
Structure, including upper surface and front end face, long stripes through hole is offered on upper surface, conductive coating is provided with long stripes through hole, leads
The shape of electrocoat is corresponding with long stripes through hole, and upper surface and the insulated brush upper surface of conductive coating are located in the same horizontal plane；
Insulated brush is arranged in brush-box；Conductive coating bottom is connected with wire, and the wire other end is worn by long stripes through hole bottom
In the outside of insulated brush and brush-box.
In above-mentioned technical proposal, it is preferred that insulated brush material is non-conductive material.
In above-mentioned technical proposal, it is preferred that the width of conductive coating is less than length.
The main beneficial effect of above-mentioned insulated carbon brush provided by the utility model is：
By the way that carbon brush is arranged in insulated brush, when starting a motor, insulated brush and the copper sheet on motor rotary shaft are first
First contact, cut off electric current, when conductive coating contacts with copper sheet, produce surge current, with axis of rotation, copper sheet and and carbon brush
The insulated brush contact at rear portion, cuts off electric current, so as to ensure the Production conditions of surge current, and realizes and utilizes surge current acting
Purpose.
Conventional carbon brush is substituted by using conductive coating, on the one hand can ensure that existing carbon brush can be realized and utilize surge current
Basic function, on the other hand, because conductive coating is very narrow, so conduction time is more shorter than existing carbon brush；Simultaneously because carbon brush portion
Set up separately and be calculated as coating, therefore smaller volume is can be designed as compared to existing carbon brush so that the application of carbon brush substantially expands.
Brief description of the drawings
Fig. 1 is the diagrammatic side-view cross-sectional structural representation of insulated carbon brush.
Fig. 2 is the schematic top plan view of insulated carbon brush.
Wherein, 1, conductive coating, 2, insulated brush, 3, brush-box, 4, wire.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：
As depicted in figs. 1 and 2, its be insulated carbon brush structural representation.
Insulated carbon brush of the present utility model includes conductive coating 1 and insulated brush 2, and insulated brush 2 is in rectangular parallelepiped structure, insulated brush
Long stripes through hole is set on 2 upper surface, there is conductive coating 1 in long stripes through hole, insulated brush 2 is provided with brush-box 3, carbon brush
The height of box 3 is less than the height of insulated brush 2, and the upper surface of brush-box 3 is located at the middle part of the side of insulated brush 2.
The material of insulated brush 2 is non-conductive material, and insulated brush 2 is provided with long stripes through hole, long stripes through hole on upper surface
Conductive coating 1 is inside provided with, the upper surface and the upper surface of insulated brush 2 of conductive coating 1 are located in the same horizontal plane, conductive coating
1 shape is engaged with long stripes through hole shape, and the length of conductive coating 1 is more than width；The bottom of conductive coating 1 is provided with energization
Wire 4, the other end of wire 4 through insulated brush 2 and brush-box 3 and are connected to outside carbon brush.
After energization, the copper sheet on motor rotary shaft first contacts, now circuit, which is in, disconnects with axis of rotation with insulated brush 2
State, when copper sheet contacts with conductive coating, circuit turn-on, produce surge current and do work, subsequent copper sheet contacts carbon brush 1 again
The insulated brush 2 at rear, circuit disconnect；By circulating said process, ensure the Production conditions of surge current, and realize and utilize surge
The purpose of current work.
Existing carbon brush is substituted by using conductive coating 1, carbon brush material can be saved, shortens conduction time, and can is according to need
Will, by the volume-diminished of carbon brush, applying it to needs small, micromotor occasion, expands its application.
Specific embodiment of the present utility model is described above, in order to which those skilled in the art understand
The utility model, it should be apparent that the utility model is not limited to the scope of embodiment, to the common skill of the art
For art personnel, if various change in the spirit and scope of the present utility model that appended claim limits and determines,
These changes are it will be apparent that all utilize the innovation and creation of the utility model design in the row of protection.
