Abstract
The utility model discloses a high ripple current-resistant aluminum electrolytic capacitor. The high ripple current-resistant aluminum electrolytic capacitor comprises a shell, an anode guide pin, a cathode guide pin, electrolytic paper, an anode foil and a cathode foil and is characterized in that: a layer of second electrolytic paper is arranged between the anode foil with the anode guide pin and the electrolytic paper; a layer of second electrolytic paper is arranged between the cathode foil with the cathode guide pin and the electrolytic paper; and a gasket foil is covered on the joint of the cathode guide pin and the cathode foil. According to the high ripple current-resistant aluminum electrolytic capacitor, a layer of electrolytic paper is added between the anode foil and the cathode foil, so that the problem of short circuit and breakdown exist on the capacitor because burrs puncture the electrolytic paper is solved. The electrolytic paper is added, so that the bad influence brought by the heating of products is reduced, and the service lift of the products is prolonged; and the gasket foil is covered on the joint of the cathode guide pin and the cathode foil, so that the electrolytic capacitor can withstand the reverse voltage and higher temperature.
Description
Technical field
The utility model relates to a kind of capacitor, relates to a kind of aluminium electrolytic capacitor of anti-high ripple current specifically.
Background technology
At present; Existing aluminium electrolytic capacitor includes the sub-prime and that a shell, is arranged in the said shell and is arranged at the Jiao Gai in the said shell, and sub-prime stings the capacitor guide pin of riveting on said anode foils and Cathode Foil respectively by an anode foils, a Cathode Foil, at least one electrolytic paper and two and constitutes.Because the capacitor guide pin directly stings riveting in Cathode Foil, the burr of guide pin tongue pierces through the performance that electrolytic paper has not only influenced aluminium electrolytic capacitor easily, also exists potential safety hazard; The tongue of cathode foil and guide pin links through the thorn riveting in addition, and this place electrochemical reaction will take place and produces a large amount of heat during energising, and heat is accumulated in aluminium electrolytic capacitor, is prone to cause that the electrolyte in the aluminium electrolytic capacitor is withered, finally causes aluminium electrolytic capacitor to lose efficacy.
Summary of the invention
To the deficiency of above-mentioned prior art, the purpose of the utility model provides the aluminium electrolytic capacitor of the anti-high ripple current of a kind of stable performance, long service life.
To achieve these goals; The technical scheme that the utility model adopts is: a kind of aluminium electrolytic capacitor of anti-high ripple current; Comprise shell, anode guide pin, negative electrode guide pin, electrolytic paper, anode foils and Cathode Foil, between anode foils that contains the anode guide pin and electrolytic paper, be provided with one deck second electrolytic paper; Between Cathode Foil that contains the negative electrode guide pin and electrolytic paper, be provided with one deck second electrolytic paper equally, be coated with a liner paper tinsel in the junction of negative electrode guide pin and Cathode Foil.
Preferably, said liner paper tinsel is the negative pole aluminium foil, and its length is less than the width of electrolytic paper.
Preferably, said second electrolytic paper also covers electrolytic paper fully from the roll set extension.
Compared with prior art; The useful technique effect of the utility model is: the utility model makes becoming of original one deck two-layer owing to be between anode foils and Cathode Foil, to increase one deck electrolytic paper, prevents that effectively burr from piercing through electrolytic paper and causing switching between the positive and negative paper tinsel; Solve Yin Maoci and punctured the capacitor short-circuit puncture that electrolytic paper causes; Because of increasing electrolytic paper, reduced the harmful effect that the product heating brings, prolonged life of product; Because the junction in negative electrode guide pin and Cathode Foil covers the liner paper tinsel, has therefore increased new current path, makes electrolytic capacitor can bear reverse voltage and higher temperature, improves the anti-ripple current ability of product.
