Description
Technical field
The present invention relates to electrical equipment technical field more particularly to a kind of new type nut gaskets for power equipment.
Background technology
Currently, in the power system, most of power equipment is attached using conducting wire, and conducting wire is needed through fixed spiral shell
Bolt, nut and gasket are fixed on power equipment, since the power equipment operation time limit is longer or running environment is poor, can be led
Fixing bolt, nut and gasket corrosion are caused, is generated heat so as to cause the place of being bolted, even can blow conducting wire and fixation when serious
Bolt, traditional processing mode is that the fixing bolt, nut and gasket of corrosion are polished, then in fixing bolt, nut
And gasket surface applies one layer of conductive paste, this mode only increases the conductive capability on surface, and the contact surface of nut and gasket
Due to can not brushing conductive paste, contact resistance is larger, and fever is still easily caused when load is heavier, or even burns conducting wire and fixation
Bolt seriously affects power supply reliability, it is therefore desirable to a kind of novel nut shim is proposed, to solve these problems.
Invention content
Present invention solves the technical problem that：A kind of new type nut gasket for power equipment is provided, it is traditional to solve
The contact surface of nut shim and nut can not brushing conductive paste cause contact resistance excessive, to easily cause fever, or even burn
The problem of ruining conducting wire.
Technical scheme of the present invention：
A kind of new type nut gasket for power equipment, including the identical upper and lower surface of shape, the upper surface
The circular bolt holes there are one position face are respectively provided with lower surface middle part, the upper and lower surface combines to form one
Cavity is provided with conducting paste in the cavity, and the upper and lower surface is both provided with several compression lotions and leads
Go out aperture.
The conducting paste component includes silver powder, metallic tin powder, metal lead powder and vaseline lotion, described each
Constituent mass percentage is as follows：Silver powder is 30%-40%, metallic tin powder 10%-20%, metal lead powder 5%-10%, all scholars
Woods lotion is 35%-50%.
The cavity thickness is 0.3-0.5mm.
The compression lotion export hole diameter is 0.01-0.2mm.
The upper surface and the lower surface is made of aluminium, iron, steel, copper or aluminum alloy materials.
The silver powder, metallic tin powder, metal lead powder diameter are 0.005mm.
Beneficial effects of the present invention：A kind of new type nut gasket for power equipment is provided, by being arranged in gasket
Conductive paste is arranged in cavity, and several compression lotions are arranged in the upper and lower surface of gasket and export aperture for cavity, in fastening nut
When, nut extruding pad squeezes out the conductive paste in gasket air along compression lotion export aperture, can uniformly apply conductive paste
Be located on the contact surface of nut and gasket, meanwhile, conducting paste is matched according to a certain percentage, conductive effect more preferably,
The contact resistance between nut and gasket is effectively reduced, avoids because contact resistance is excessive, bolt is caused to generate heat, to draw
The problem of playing fixing bolt, nut, gasket or even conducting wire scaling loss, it is ensured that the safety of power equipment and the stability of power supply, tool
There is higher practical value.
Description of the drawings
Fig. 1 is surface structure schematic diagram of the present invention；
It is identified in figure：1, upper surface, 2, lower surface, 3, bolt hole, 4, compression lotion export aperture, 5, cavity.
Specific implementation mode
The present invention is described further below in conjunction with the accompanying drawings, a kind of novel spiral for power equipment of the present invention
Female gasket, including the identical upper surface 1 of shape and lower surface 2, in the upper surface 1 and lower surface 2 be respectively provided with there are one
The circular bolt holes 3 of position face, 3 diameter of bolt hole match with the fixing bolt used, the upper surface 1 and following table
The combination of face 2 forms the cavity 5 that a thickness is 0.3-0.5mm, and conductive paste, the upper surface 1 are provided in the cavity 5
The compression lotion that several a diameter of 0.01-0.2mm are both provided with lower surface 2 exports aperture 4, the upper surface 1 and following table
Face 2 is aluminium or copper at copper and aluminium have good conductive property, and can be effectively increased conductive reliability, it is ensured that powered stable.
The conducting paste component includes silver powder, metallic tin powder, metal lead powder and vaseline lotion, described each
Constituent mass percentage is as follows：Silver powder is 30%-40%, metallic tin powder 10%-20%, metal lead powder 5%-10%, all scholars
Woods lotion is 35%-50%, and the silver powder, metallic tin powder, metal lead powder diameter are 0.005mm.
In fastening nut, nut extruding pad squeezes the conductive paste in gasket cavity 5 along compression lotion export aperture 4
Go out, on the contact surface of conductive paste uniformly can be laid in nut and gasket, meanwhile, conducting paste is matched according to a certain percentage
