Description
Technical field
This utility model is related to static suppressor field, especially a kind of new miniature static suppressor.
Background technology
Electrostatic is that one kind is present in body surface, reflects its positive and negative charge unbalanced phenomenon in subrange, it
Mainly pass through the contact of material and separate, electrostatic induction, the physical process such as dielectric polorization and charged corpuscle attachment produce, performance
Higher for voltage, the persistent period is very short, the features such as release energy strong.With the development of rapid photo detector, electrostatic is to unit
Harm caused by device application is more and more obvious.The purpose introducing electrostatic protection element seeks to avoid operating circuit to become quiet
The path of discharge of electricity and damaged, this element not only will can absorb electrostatic induced current, the voltage of clamp operating circuit, prevents it
Impaired due to voltage overload, also will can when electrostatic occurs quick response, while protection circuit, self structure nor
Damaged.Electrostatic protection has become as the key factor that need to consider during overvoltage protection design.
Constantly the safety consciousness of lifting promotes and expands the development of over-current over-voltage protection product, in product design, no
The performance requirement of circuitry only to be ensured, is more intended to focus on their security feature.Electronic system be often subject to extraneous because
Element interference, for example break-make inductive load or start and stop high power load, line fault, thunder and lightning etc. cause instantaneous overvoltage or overcurrent
Phenomenon, they have serious harm for the trouble free service of electronic system, gently then lead to equipment fault, signal interruption；Heavy then lead to
Equipment and cable burn, and jeopardize the safety of operator, lead to major accident.So generally requiring design anti-surge protective device
In order to electronic equipment and transmission line of electricity are carried out with the protection of overvoltage, two aspects of excessively stream.Traditional overcurrent protection needs in circuit
Middle serial fuse structure, causes metal bath exothermic melting and disconnecting circuit using overcurrent；Equally, traditional overvoltage guarantor
Shield to be realized with shunting mode parallel connection over-voltage protection element, typically by surge voltage and the earth short circuit, so that surge current is diverted into
Ground, reaches weakening and eliminates overvoltage, the purpose of overcurrent, thus playing the effect that protection electronic equipments safety runs.But this
Discrete excessively stream and over-voltage protector, in addition to defencive function is single, also there are a lot of defects a bit, as slower in response speed,
Reliability and stability difference etc.；On the other hand, with the continuous enhancing of electronic functionalities, the density of its internal component also exists
Constantly rise, thus it requires the components and parts with identical operating current, voltage and resistance to stream grade can reduce its size further.
Protection element market is just tending to modularity, the developing direction of miniaturization, high-power and over-voltage and over-current integration at present.
Integrated PPTC critesistor and metal-oxide MOV in a device are proposed in United States Patent (USP) US7660096B2
Varistor technology, thus decreasing space requirement and the device count of circuit board, can meet and telephone communication set is included
The protection of the destructions such as thunderbolt, static discharge, equipment contact power line and alternating current circuit sensing, it is right in overcurrent event to contribute to
Electric current is limited, and has overvoltage strangulation ability；After fault condition is excluded and switched on power, can be resetted again,
Communication equipment can continue to run with；But due to such product be three end pin form structures it is impossible to meet the demand of surface soldered, and
Small product size is larger, no clear superiority in application.Propose one kind in United States Patent (USP) US6636404B1, US6982859B1 to exist
Fuse shell porcelain tube surface forms a quick function phase of lamination, and is connected with fuse one termination electrode, in porcelain using bonding process
Form side electrode, thus overvoltage protection and overcurrent protection are encapsulated in an element, this kind of product design is simpler in the middle part of pipe
Single, but batch continuous production realization is difficult and relatively costly.
Therefore, the problems referred to above are necessary to propose a kind of new miniature static suppressor.
