Description
Technical field
The utility model relates to a kind of aluminium electrolytic capacitor, belongs to the capacitor technology field.
Background technology
At present, the tongue thorn riveting of existing its positive and negative guide pin of aluminium electrolytic capacitor is on the positive and negative electrode aluminium foil, because alternating floor electrolytic paper only between the positive and negative paper tinsel, the burr of its cathode foil guide pin tongue contacts with electrolytic paper, and burr may pierce through electrolytic paper and cause the short circuit puncture; The tongue of cathode foil and guide pin links by the thorn riveting in addition, and this place electrochemical reaction will take place and produces a large amount of heat during energising, causes life of product to shorten.
Summary of the invention
The purpose of this utility model provides a kind of rate of finished products height, stable performance, long-life aluminium electrolytic capacitor.
For realizing above purpose, the technical solution of the utility model provides a kind of aluminium electrolytic capacitor, comprise anode foils, Cathode Foil, the a electrolytic paper, the b electrolytic paper, negative guide pin, positive guide pin, end loose adhesive tape, between anode foils and Cathode Foil, be provided with a electrolytic paper, in Cathode Foil with end and be provided with the b electrolytic paper between the loose adhesive tape, negative guide pin, anode foils is connected with the tongue of negative guide pin with positive guide pin by the thorn riveting, it is characterized in that, be provided with the c electrolytic paper between anode foils and a electrolytic paper or between Cathode Foil and a electrolytic paper, between Cathode Foil and b electrolytic paper or Cathode Foil and end and be provided with the d electrolytic paper between the loose adhesive tape.
Described a electrolytic paper, b electrolytic paper, c electrolytic paper and d electrolytic paper are from the roll set extension and cover cathode foil and anode foil fully.
The utility model is to reach in Cathode Foil between anode foils and the Cathode Foil and ending increase one deck electrolytic paper between the loose adhesive tape, make becoming of original one deck two-layer, this electrolytic paper has covered positive and negative aluminium foil, prevent 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, simultaneously, because of increasing electrolytic paper, reduce the harmful effect that the product heating brings, prolonged life of product.Through test, the short circuit puncture rate that is caused by positive and negative paper tinsel burr is reduced to 10ppm by original 0.3%, prolongs 20% ~ 40% useful life.
The utility model has the advantages that rate of finished products height, stable performance, long-life.
Description of drawings
Fig. 1 is a kind of aluminium electrolytic capacitor structural representation.
