Description
Technical field
The present invention relates to a kind of carbon brush and carbon brush cartridges.
Background technique
In motor, carbon brush and commutator sliding contact are protected so that the current direction generating period of rotor coil changes
Card rotor persistently rotates in magnetic field, as shown in figure 4, in the prior art, elongated slot is generally machined on brush-box, by artificial
After pressing pressing spring, then carbon brush connection sheet is inserted on elongated slot, the elastic force of pressing spring makes brush body and electric current loop against together
When, carbon brush connection sheet is fixed on carbon brush box body, and for this mounting means by having been manually done, working efficiency is low, to guarantee peace
Stability after dress, pressing spring have biggish elastic force, and there is also certain difficulty for practical pressing.
Summary of the invention
Aiming at the shortcomings existing in the above problems, the present invention provides a kind of carbon brush and carbon brush cartridge.
To achieve the above object, the present invention provides a kind of carbon brush and carbon brush cartridge, comprising:
Brush-box, the brush-box are made of the carbon brush box body being symmetrically installed, and the inside of the carbon brush box body processes elongated slot,
Outside machining deformation slot, the deformation slot position is in the lower section of the elongated slot;
Carbon brush, the carbon brush is fixedly connected with brush body by pressing spring, carbon brush connection sheet is formed.
As a further improvement of the present invention, the carbon brush box body is made of polyformaldehyde, and the top of the elongated slot is machined with
Guide surface.
As a further improvement of the present invention, the bottom of the brush body is curved surface, the external shape of the curved surface and commutator
Shape coincide.
As a further improvement of the present invention, the middle part of the carbon brush connection sheet is thin mouth section, the size of the thin mouth section
It is matched with the elongated slot.
As a further improvement of the present invention, the carbon brush connection sheet is fixedly connected with external connection.
As a further improvement of the present invention, the brush body, the pressing spring, the carbon brush connection sheet are by conductive metal system
At.
The invention has the benefit that
The brush body of carbon brush is packed into brush-box, presses carbon brush connection sheet, by the flexible deformation on carbon brush box body top, i.e.,
It can easily realize installation of the carbon brush in brush-box, operation is convenient laborsaving, meanwhile, carbon brush connection sheet and pressing spring are fixed companies
It connects, has good electric conductivity.

Specific embodiment
As shown in Figure 1 and Figure 2, a kind of carbon brush and carbon brush cartridge described in the embodiment of the present invention, including brush-box 1, carbon brush
Box 1 is made of the carbon brush box body 11 being symmetrically installed, and carbon brush box body 11 is made of polyformaldehyde, and the inside of support body 11 processes elongated slot
112, outside machining deformation slot 111, deformation slot 111 is located at the lower section of elongated slot 112, and the top of elongated slot 112 is machined with guide surface
113;Carbon brush 2 is fixedly connected with brush body 21 by pressing spring 22, carbon brush connection sheet 23 is formed, and the bottom of brush body 21 is curved surface, curved surface with
The outer circular shape of commutator coincide, and the middle part of carbon brush connection sheet 23 is thin mouth section 231 (shown in Fig. 3), the size of thin mouth section 231 with
Elongated slot 112 matches, and carbon brush connection sheet 23 is fixedly connected with external connection 3, and brush body 21, pressing spring 22, carbon brush connection sheet 23 are by conduction
Metal is made.
The brush body of carbon brush is packed into brush-box, presses carbon brush connection sheet, by the flexible deformation on carbon brush box body top, i.e.,
It can easily realize installation of the carbon brush in brush-box, operation is convenient laborsaving, meanwhile, carbon brush connection sheet and pressing spring are fixed companies
It connects, has good electric conductivity.
When specifically used, for convenience of the present invention is understood, it is described in conjunction with attached drawing;
Fig. 4 is the carbon brush and carbon brush cartridge before improving, and carbon brush connection sheet is not fixedly connected with pressing spring, in reality
In the use process of border, easily there is the phenomenon that circuit is not turned on, influences the working effect of motor, meanwhile, by overcoming pressing spring
Carbon brush connection sheet is embedded into elongated slot by elastic force also has certain operation difficulty, inconvenient for operation necessarily to lead to working efficiency
It has a greatly reduced quality.
In technical solution of the present invention, brush body is fixedly connected by pressing spring with carbon brush connection sheet, forms carbon brush, carbon brush is under
Side commutator (being not drawn into figure) against, contact it is moderately good, meanwhile, during carbon brush is installed in brush-box, lead to
Crossing the mode directly pressed makes the port of carbon brush box body along deformation slot deformation, under the guiding role of guide surface, carbon brush connection sheet
In into elongated slot (thin mouth section is stuck in elongated slot), installation is very convenient, laborsaving, and the connection of carbon brush and brush-box is stronger can
It leans on.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, made any to repair
Change, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
