Abstract
The utility model discloses an aluminum electrolytic capacitor. The aluminum electrolytic capacitor comprises an aluminum housing. A capacitor core is mounted in the aluminum housing and comprises a positive-pole foil layer and a negative-pole foil layer. A separating layer is arranged between the positive-pole foil layer and the negative-pole foil layer. The capacitor core is formed by winding the positive-pole foil layer, the negative-pole foil layer, and the separating layer. The separating layer comprises a plastic insulating layer, a conductive film, and a metallic oxide insulating layer. The conductive film is arranged between the plastic insulating layer and the metallic oxide insulating layer. The aluminum electrolytic capacitor enhances the applicability to different electrical environment of the capacitor.
Description
Technical field
The utility model relates to aluminium electrolytic capacitor, belongs to the electric component technical field.
Background technology
Electrolytic capacitor generally is to be made of aluminum hull, capacitor core and Jiao Gai.Wherein capacitor core is to be reeled by four plies such as anode metal paper tinsel, electrolytic paper, cathodic metal paper tinsel, electrolytic papers, handles forming again through impregnation electrolyte.The cathodic metal platinum of capacitor core generally adopts normal aluminium foil to make, and can not bear the impact of reverse leakage current, thereby shortened the useful life of electrolytic capacitor.
Summary of the invention
At the defective of prior art, the utility model discloses a kind of aluminium electrolytic capacitor, by the architecture advances to capacitor core, can enough adapt to electric current and the voltage of various polarity, can be not breakdown, improved its useful life.
For achieving the above object, the utility model is achieved through the following technical solutions:
Aluminium electrolytic capacitor, comprise aluminum hull, the electric capacity core body is installed in the aluminum hull, have positive polarity paper tinsel layer and negative polarity paper tinsel layer in the electric capacity core body, has separator between positive polarity paper tinsel layer and the negative polarity paper tinsel layer, positive polarity paper tinsel layer, negative polarity paper tinsel layer, separator are reeled and are formed the electric capacity core body, and described separator is made up of plastic insulating layer, conducting film, metal oxide insulating barrier, and conducting film is between plastic insulating layer and metal oxide insulating barrier.
In said structure, owing between separator, be provided with independent conductive layer, when running into reverse current, metal ion athletic meeting on the conductive layer replaces the electrolyte conduction, thereby reduced the impact of the reverse current that acts on electric capacity core body electrolyte itself, thereby the breakdown problem of capacitor can not occur, guarantee the useful life of product.
In the utility model, the concrete structure of capacitor is: have opening on the described aluminum hull, by the cover plate for sealing opening, positive polarity paper tinsel layer, negative polarity paper tinsel layer are connected with corresponding electrode pin respectively and pass cover plate.
In order to prevent leaky condenser, the inner and outer wall of described aluminum hull all is coated with dielectric film.
Because capacitor caloric value when the electric leakage problem occurring can sharply increase, described aluminum hull bottom has metallic heat radiating plate, directly contacts with negative polarity paper tinsel layer.The heat of capacitor inside can be exhaled rapidly in this way.
By above-mentioned improvement, aluminium electrolytic capacitor of the present utility model is adapted to multiple different electric circumstance.
Description of drawings
Fig. 1 is the structural representation of the utility model aluminium electrolytic capacitor;
Fig. 2 is the profile of the used separator of the utility model aluminium electrolytic capacitor capacitor core.
Embodiment
With reference to the accompanying drawings 1, aluminium electrolytic capacitor of the present utility model, comprise aluminum hull 4, all have dielectric film 3,5 on the medial surface of aluminum hull and lateral surface, the opening part of aluminum hull is by cover plate 1 sealing, capacitor core 2 is installed in the aluminum hull, two pins of capacitor core 2 pass cover plate, and the bottom of aluminum hull has metallic heat radiating plate 6, and capacitor core is by positive polarity paper tinsel layer and negative polarity paper tinsel layer, separator between positive polarity paper tinsel layer and the negative polarity paper tinsel layer is reeled and is formed, and wherein negative polarity paper tinsel layer directly contacts with metallic heat radiating plate.
With reference to the accompanying drawings 2, shown the profile of used separator to be respectively PET plastic insulating layer 71 and alumina metals oxide insulating layer 72 in the both sides of conductive layer 7.
