Abstract
The utility model discloses an aluminum electrolytic capacitor with a novel sealing structure. The aluminum electrolytic capacitor comprises a capacitor element, a pole lug which is arranged on the capacitor element and is capable of leading capacitance out and an aluminum plastic film which is used for enveloping the capacitor element. The sealing mode used by the utility model is as follows: the capacitor element is sealed by using an aluminum plastic film packaging method and the capacitance is led out in a pole lug mode. In addition, a square capacitor sealing method can also be used. The aluminum plastic film provided by the utility model has the following advantages of easiness for molding, light weight, small thickness, and the like; with the adoption of the aluminum electrolytic capacitor, the traditional sealing mode of the aluminum electrolytic capacitor is greatly improved.
Description
Technical field
The utility model relates to a kind of capacitive means, belongs to the electric elements technical field, particularly relates to a kind of aluminium electrolytic capacitor with novel sealing structure.
Background technology
The alminium electrolytic condenser sealing means of Now the present is that aluminum hull entangles sub-prime, and wears the guide pin sealed capacitor with serum cap, clamps serum cap with machine roller compression aluminum hull head again, and this is existing aluminium electrolytic capacitor encapsulating method commonly used.
Now, in response to trend toward miniaturization, the size of aluminium electrolytic capacitor is done less and less, the also corresponding miniaturization of relative Jiao Gai and the specification of aluminum hull, and therefore caused sub-prime to wear into the aluminum hull degree of difficulty increases.In addition, the aluminium electrolytic capacitor of every exploitation new spec just needs new corresponding aluminum hull and glue lid size, and this has just increased too much cost, and these shortcomings can be amplified gradually because of the trend of in the future miniaturization.
Thereby one of ordinary skill in the art are in the urgent need to proposing a kind of new improved technique scheme, in order to solve the technical barrier of current aluminium electrolytic capacitor miniaturization.
Summary of the invention
In order to change the shortcoming of prior art, the purpose of this utility model is to provide a kind of aluminium electrolytic capacitor with novel sealing structure, considers another counterpart mode, gives up old aluminum hull and glue lid mode, adopts the aluminum plastic film method for packing.
The purpose of this utility model and to solve its technical problem be to adopt following technical scheme to realize.A kind of aluminium electroloysis with novel sealing structure according to the utility model proposes comprises: sub-prime; Be arranged at the lug that also can draw electric capacity on the described sub-prime; And the aluminum plastic film of wrapping up in described sub-prime for envelope.
Described sub-prime adopts circular sub-prime, and described circular sub-prime is to be reeled by positive pole aluminium foil, negative pole aluminium foil, electrolytic paper and adhesive tape to form.
Its material of described aluminum plastic film is to be combined by aluminium lamination, CPP material layer and nylon material layer.
Described sub-prime adopts square sub-prime, and described square sub-prime is layer structure, comprises respectively: the first electrolytic paper, the first anode foil, the first cathode foil, the second electrolytic paper, the second anode foil, the second cathode foil and the 3rd electrolytic paper.
Described aluminum plastic film can be the Double-layer aluminum plastic film that comprises ground floor aluminum plastic film and second layer aluminum plastic film.
By technique scheme, the advantage that the utlity model has is:
The sealing mode that the utility model adopts is to seal sub-prime with the aluminum plastic film pack, and the mode of using lug instead is drawn capacity.In addition, also can be applied to the sealing method of square electric capacity.Aluminum plastic film of the present utility model has the advantages such as easy-formation, lightweight, thin thickness, for the sealing mode of now the aluminium electrolytic capacitor benefit that has greatly improved.
