Abstract
The utility model discloses a take electronic device of explosion-proof fire prevention function, including shell body and electronic component, the shell body is seal structure, and electronic component locates in this sealed shell body, and electronic component's pin exposes the shell body, has the space between shell body and electronic component, it has liquid or gaseous filler to fill in the space. The utility model overcomes prior art's defect has good explosion-proof and fire prevention effect.
Description
Technical field
The utility model relates to a kind of electronic device with the anti-explosion fire function.
Background technology
Along with development of electronic technology, electronic device also obtains application more and more widely, as all can adopt electronic device in household electric appliances, in the electric equipment.Wherein the portions of electronics device produces short circuit, blast even on fire in the meeting of losing efficacy, and life or property are brought huge hidden danger.
At this potential safety hazard, the applicant also once disclosed a kind of electronic device anti-explosion fire device in Chinese utility model patent 200420071379.7, this device major technique measure is the non-airtight shell fully that high temperature flame-proof ABS plastic of cover is made on electronic device, and this shell must reach the requirement of UL94-V0 fire safety grade.Simultaneously; between described shell and electronic device, also leave the space; in described space, be filled with granular substance such as quartz sand etc.; utilize these granular substances can absorb the characteristic of heat energy and kinetic energy; when electronic device was blasted, the energy absorption that the granular substance in the gap can produce blast added the protection of the above shell; make electronic device blast and on firely all only occur in described enclosure, thereby improve the security reliability of electronic device greatly.
But in order to guarantee that the energy that the electronic device blast produces can in time obtain discharging, must offer the spilehole that granular substance is in communication with the outside on the described shell, and the size of aperture is moderate, the granular substance of filling is spilt, the gas that produces that can guarantee again to explode in time obtains discharging, this technical scheme can effectively be avoided the generation of the explosion-proof accident of electronic device, but because this technical scheme shell has pore, inside is filled with granular substance such as quartz sand, and there are two problems in present structure:
1, granular substance such as quartz sand absorb water under wet environment, reduce the insulation between the electronic device pin, cause accidents such as electric leakage and arcing and take place;
2, owing to have pore, tiny particle object such as quartz sand dust then might spill from pore, pollute circuit board.Cause.
Summary of the invention
The purpose of this utility model is to overcome the defective of prior art, and a kind of electronic device is provided, and the utility model has overcome the defective of prior art, has good explosion-proof and flameproof effect.
Its technical scheme is as follows:
A kind of electronic device with the anti-explosion fire function, comprise shell body and electronic component, described shell body is a hermetically-sealed construction, electronic component is located in the shell body of sealing, and the pin of electronic component exposes shell body, between shell body and electronic component, have the space, be filled with the filler of liquid state or gaseous state in the described space.
The technical scheme of the further refinement of aforementioned techniques scheme can be:
Described filler is an inert gas, as adopting helium, neon, argon gas, krypton gas, xenon, radon gas etc.
Described filler is a transformer oil, when selecting transformer oil for use, is preferably the mineral oil that meets GB 2536 " transformer oil " requirement.
Described shell body can be cylinder, square or spherical.
Described shell body is the heat-resistant fireproof shell.
In sum; the utility model has the advantages that: shell body adopts hermetically-sealed construction; can avoid extraneous water or foreign material to enter in the shell body; after the electronic component blast; shell body can play effective protective effect; liquid state or gaseous state filler in the shell body can play datonation-inhibition effect simultaneously, avoids owing to the electronic component blast causes circuit board damage or initiation fire.

Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated:
Embodiment one
As shown in Figure 1, a kind of electronic device with the anti-explosion fire function, comprise shell body 1 and electronic component 2, described shell body 1 is a hermetically-sealed construction, electronic component 2 is located in the shell body 1 of sealing, and the pin 3 of electronic component 2 exposes shell body 1, has the space between shell body 1 and electronic component 2, is filled with the filler 4 of liquid state or gaseous state in the described space.
In the present embodiment, described filler 4 is an inert gas, and described shell body 1 is a cylinder, adopts the heat-resistant fireproof material to make.
Because shell body 1 adopts hermetically-sealed construction; can avoid extraneous water or foreign material to enter in the shell body 1; after electronic component 2 blasts; shell body 1 can play effective protective effect; liquid state or gaseous state filler 4 in the shell body 1 can play datonation-inhibition effect simultaneously, avoids owing to electronic component 2 blasts cause circuit board damage or initiation fire.
Embodiment two
As shown in Figure 2, in the present embodiment, described filler 4 adopts transformer oil, and described shell body 1 is a cube structure.Present embodiment is identical with the principle of embodiment one, repeats no more herein.
Only be specific embodiment of the utility model below, do not limit protection range of the present utility model with this; Any replacement and the improvement done on the basis of not violating the utility model design all belong to protection range of the present utility model.
