There is the shell of covering linkage section.
Further, above-mentioned shell is triangle shell.
Further, the end of above-mentioned pin forms bending section after being stretched to shell extension.
A kind of high-energy varistor provided by the utility model, is set using the structure of improved structure and tin layers
Meter, using high-energy varistor, can be equivalent to raising under conditions of voltage-dependent resistor is constant compared to the prior art
The surplus capacity that surge energy absorbs, and electronic equipment uses safer, longer life expectancy.
Description of the drawings
By reading the detailed description of hereafter preferred embodiment, various other advantages and benefit are common for this field
Technical staff will become clear.Attached drawing only for the purpose of illustrating preferred embodiments, and is not considered as to this practicality
Novel limitation.And throughout the drawings, the same reference numbers will be used to refer to the same parts.In the accompanying drawings：
Fig. 1 is a kind of structural schematic diagram for high-energy varistor that the utility model embodiment provides.
Specific implementation mode
The exemplary embodiment of the disclosure is more fully described below with reference to accompanying drawings.Although showing the disclosure in attached drawing

There are pin 22, chip portion 1 to be coated with shell 3.
A kind of high-energy varistor that the present embodiment is provided, is set using the structure of improved structure and tin layers
Meter, using high-energy varistor, can be equivalent to raising under conditions of voltage-dependent resistor is constant compared to the prior art
The surplus capacity that surge energy absorbs, and electronic equipment uses safer, longer life expectancy.
After using above-mentioned structure, the maximum impact electric current in chip portion 1 is 4000-13000A, is specifically as follows
10D:4000A、14D:8000A and 20D:13000A；Its " 10D compared to the maximum impact electric current in existing chip portion:
2500A；14D:4500A；20D:6500A " is greatly improved, when varistor meets with lightning stroke or surge voltage, varistor meeting
The energy for absorbing invasion electronic equipment, to protect late-class circuit.If the limit that varistor absorbs energy is less than invasion
When energy, varistor can be damaged to release energy.
Because of size constancy, existing production technology can produce the product completely；Although the maximum impact electric current of product becomes
Greatly, but original testing equipment is up to 20KA, also meets the testing requirement of the product.As long as existing pass through relevant world security
Specification certification.
