Abstract
The utility model discloses a film coated aluminum shell for a capacitor. The film coated aluminum shell comprises an aluminum shell body (1) and insulating coating film (2) arranged outside the aluminum shell, wherein the thickness of the insulating coating film is 5-16 microns. The film coated aluminum shell adopts the process of coating film first and then pressing on an aluminum plate, the average thickness of the insulating coating film coated on the aluminum plate is only half of that of the prior art, so that the deformation of the film layer is small during pressing, thereby solving the phenomena of deformation, displacement and dropout of the film layer and the surface of the aluminum shell and greatly improving the rate of certified products when pressing insulating aluminum shells with film coated aluminum plates. Simultaneously, the thermal resistance and the expansion and contraction adaptability are also improved.
Description
Technical field
The utility model relates to a kind of capacitor aluminum hull of filming, and belongs to the capacitor technology field.
Background technology
Capacitor, the shell that mainly is electrolytic capacitor forms with the pure aluminum plate punching out, outer surface at aluminum hull has one deck insulating material, and preventing by high electrical breakdown, and this one deck insulating material also will have certain thermal endurance to bear the heat that capacitor is produced when assembly welding and the work.The most frequently used method that installs insulating material outside aluminum hull additional is to put to mould cover outside aluminum hull, but since cover to mould the cover operation cumbersome, and bring secondary pollution again, therefore, the method for pasting a layer insulating before the punching out aluminum hull earlier on aluminium sheet has been arranged again.Also have and make the back at aluminum hull and directly apply insulating coating, a kind of " Electrolytic Capacitor Insulating Aluminum Shell " disclosed as Chinese utility model patent ZL03232446.4, this Electrolytic Capacitor Insulating Aluminum Shell, " outer surface at aluminum hull evenly applies one deck dielectric film, and the thickness of described dielectric film is 16～24 μ m ".The thickness of this coating is bigger, and blocked up insulating barrier has also increased heat transmission resistance and increased the possibility of being expanded with heat and contract with cold and destroying.Simultaneously, succeed in developing recently be a kind of after directly applying one deck dielectric film on the aluminium sheet again punching out become the technology of aluminum hull, simpler, the better effects if of this scheme.Owing to be after being coated in film on the aluminium sheet, carry out stretch moulding just of punching out again, and through applying the overlay film aluminium sheet of upper nonconductive Film layer, its whole extensibility is not only the restriction that is subjected to the material of rete own, and it is relevant with the thickness of rete, practice finds that the overlay film aluminium sheet of average 16～24 μ m coats is difficult for punching out and becomes the insulation aluminum hull, or percent defective is very high, its rete and aluminum hull surface often deform displacement, phenomenon such as come off.
Summary of the invention
At above-mentioned deficiency, the utility model is exactly that a kind of thinner capacitor of rete aluminum hull of filming that is coated with will be provided.
The capacitor of the present utility model aluminum hull of filming has the outer insulating coating film of aluminum hull body and aluminum hull, and the thickness of said insulating coating film is 5～16 μ m.
Better when the thickness of described insulating coating film is 8～12 μ m, and best when being 10 μ m.
The capacitor of the present utility model aluminum hull of filming, on aluminium sheet, film the earlier technology of punching out again of employing, on aluminium sheet the average thickness of coated insulating coating film than prior art little half, the rete distortion is little when making punching out, solved rete and aluminum hull surface deform displacement, phenomenon such as come off, the percentage of A-class goods of overlay film aluminium sheet punching out insulation aluminum hull improves greatly.Thermal resistance and adaptation swell-shrinking property all obtain reequiping kind simultaneously.
Description of drawings
Accompanying drawing is that the utility model one is implemented structural representation, among the figure: 1-aluminum hull body, 2-dielectric film.
Embodiment
As shown in drawings, Electrolytic Capacitor Insulating Aluminum Shell of the present utility model comprises aluminum hull body 1 and the dielectric film 2 that is coated on this external surface of aluminum hull, and the thickness of dielectric film is 10 μ m.The film withstand voltage 500V of reaching of aluminum hull of this routine capacitor, heatproof is up to 270 ℃/120sec.
Said thickness can be controlled when coating on request, makes its thickness between 5～16 μ m.
Claims (3)
1, a kind of capacitor aluminum hull of filming has the outer insulating coating film [2] of aluminum hull body [1] and aluminum hull, and the thickness that it is characterized in that said insulating coating film is 5～16 μ m.
2, the capacitor as claimed in claim 1 aluminum hull of filming, the thickness that it is characterized in that described insulating coating film [2] is 8～12 μ m.
3, the capacitor as claimed in claim 1 or 2 aluminum hull of filming is best when the thickness that it is characterized in that described insulating coating film [2] is 10 μ m.
