Abstract
The utility model discloses a lead type aluminum electrolytic capacitor with safe pressure release, which comprises an element body, a rubber stopper and an aluminum shell, wherein a thin aluminum sheet is arranged at the bottom of the aluminum shell, and the thin aluminum sheet has a thickness of 50-100 microns. By using the lead type aluminum electrolytic capacitor with the safe pressure release, which is provided by the utility model, through arranging the thin aluminum sheet at the bottom of the aluminum shell, a vaporized electrolyte overflowing is released gently; the pressure is released gently; a release effect is stable; and other components and a circuit board are effectively prevented from being damaged.
Description
Technical field
The utility model relates to a kind of aluminium electrolytic capacitor, relates in particular to a kind of wire type aluminium electrolytic capacitor with safe pressure slowly-releasing.
Background technology
At present, in existing aluminium electrolytic capacitor production technology, aluminum hull has pressure relief device, and being generally the aluminum hull bottom has explosion-proof groove, and when the alminium electrolytic condenser air pressure inside increases, can open and gas release be come out in the place that explosion-proof groove is the thinnest.See also Fig. 1, aluminium electrolytic capacitor generally comprises sub-prime body 2, plug 1 and aluminum hull 3, wherein, 4 places, aluminum hull bottom are provided with explosion-proof groove, gas when explosion-proof groove discharges because electrochemical capacitor is also bearing load, so gas can discharge always, till the electrochemical capacitor electrolyte inside is all vaporized effusion.And alminium electrolytic condenser generally all is in the complete machine, and the evaporation electrolysis liquid that overflows can condensation in complete machine, can cause the damage of other elements and wiring board and machine shell.Therefore be necessary existing wire type aluminium electrolytic capacitor is improved, it is mild to make that the evaporation electrolysis liquid that overflows discharges, and avoids damaging other elements and wiring board.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of wire type aluminium electrolytic capacitor with safe pressure slowly-releasing, and pressure discharges gently, releasing effect is stable, effectively avoid damaging other elements and wiring board.
The utility model is to solve the problems of the technologies described above the technical scheme that adopts to provide a kind of wire type aluminium electrolytic capacitor with safe pressure slowly-releasing, comprises sub-prime body, plug and aluminum hull, and wherein, described aluminum hull bottom is provided with flake aluminum.
The above-mentioned wire type aluminium electrolytic capacitor with safe pressure slowly-releasing, wherein, described flake aluminum thickness is 50 microns～100 microns.
The utility model contrast prior art has following beneficial effect: the wire type aluminium electrolytic capacitor with safe pressure slowly-releasing that the utility model provides, by flake aluminum being set in the aluminum hull bottom, it is mild to make that the evaporation electrolysis liquid that overflows discharges, pressure discharges mild, releasing effect is stable, effectively avoids damaging other elements and wiring board.
Description of drawings
Fig. 1 is existing aluminium electrolytic capacitor structural representation;
Fig. 2 is the utility model aluminium electrolytic capacitor structural representation.
Among the figure:
1 plug, 2 sub-prime bodies, 3 aluminum hulls
4 aluminum hulls bottom, 5 flake aluminums
Embodiment
The utility model will be further described below in conjunction with drawings and Examples.
Fig. 2 is the utility model aluminium electrolytic capacitor structural representation.
See also Fig. 2, the wire type aluminium electrolytic capacitor with safe pressure slowly-releasing that the utility model provides comprises sub-prime body 2, plug 1 and aluminum hull 3, and wherein, a flake aluminum 5 is set up in the bottom in aluminum hull.
The wire type aluminium electrolytic capacitor that the utility model provides, flake aluminum 5 thickness are 50 microns～100 microns, purity 99.94%～99.99%, place 4 places, aluminum hull bottom, between aluminum hull bottom and sub-prime bottom, when the aluminum hull air pressure inside increases, the explosion-proof valve of aluminum hull 3 can be opened, gas will be overflowed from the explosion-proof valve of opening, but because the existence of flake aluminum 5, gas can be subjected to earlier stopping and partial condensation before the effusion aluminum hull, at remaining gas owing to be subjected to stopping of the flake aluminum kinetic energy deficiency after the aluminum hull that causes overflowing, can only be bottom aluminum hull 4 edge carry out condensation.
Through test, used alminium electrolytic condenser of the present utility model in destructive testing detects, the amount of gas effusion aluminum hull reduce near half, escaping gas is rapid condensation then, range of scatter in sealing complete machine environment only limits to the electrochemical capacitor bottom with on every side, and other elements and complete machine plate, complete machine shell inwall are not all received influence.
Though the utility model discloses as above with preferred embodiment; right its is not in order to limit the utility model; any those skilled in the art; in not breaking away from spirit and scope of the present utility model; when doing a little modification and perfect, therefore protection range of the present utility model is worked as with being as the criterion that claims were defined.
Claims (2)
1. the wire type aluminium electrolytic capacitor with safe pressure slowly-releasing comprises sub-prime body (2), plug (1) and aluminum hull (3), it is characterized in that, described aluminum hull (3) bottom is provided with flake aluminum (5).
2. the wire type aluminium electrolytic capacitor with safe pressure slowly-releasing as claimed in claim 1 is characterized in that, described flake aluminum (5) thickness is 50 microns～100 microns.
