Embodiment Construction

[0012] Such as figure 1 and 2 As shown, the present invention includes a positive electrode foil 2 with a positive electrode guide pin 4 riveted, a negative electrode foil 1 with a negative electrode guide pin 5 riveted, spread in the electrolytic paper between the two electrode foils, and the negative electrode foil of the aluminum electrolytic capacitor before winding 1. Riveting the negative electrode guide pin at 5 places and the positive electrode foil. The liner aluminum foil 3 is arranged on the front of the positive and negative electrode foils (2, 1), and the liner aluminum foil 3 is riveted under the positive and negative electrode guide pins (4, 5).

[0013] Such as image 3 As shown, another structure of the utility model is: the liner aluminum foil 3 is riveted on the back of the negative electrode foil 1, and is riveted on the back of the negative electrode guide pin 5 together with the negative electrode foil 1 .

[0014] For the same reason, the liner alumin...

Abstract

The invention relates to an aluminum electrolysis capacitor which comprises an anode foil with a barbed and riveted anode guide pin and a cathode foil with a barbed and riveted cathode guide pin. Theanode foil and the cathode foil are laid in electrolytic paper between the two foils; and a section of liner aluminum foil is barbed and riveted at the barbed riveted cathode guide pin of the cathodefoil and the barbed riveted anode guide pin of the anode foil of the aluminum electrolysis capacitor before coiled. The invention improves the capability of bearing a ripple current by approximate 50percent and prolongs the service life by approximate 30 percent.

Description

technical field [0001] The present invention relates to an aluminum electrolytic capacitor. Background technique [0002] In the existing production process of aluminum electrolytic capacitors, the positive and negative guide pins are riveted on the positive and secondary aluminum foils, the current path has no shunt, and the discharge of the burr tip of the aluminum tongue under the electric field may easily cause a short-circuit breakdown of the capacitor. Contents of the invention [0003] The novel purpose of the present invention is to provide an aluminum electrolytic capacitor with high ripple resistance and long service life. [0004] For addressing the above problems, the solution of the present invention is: [0005] An aluminum electrolytic capacitor, comprising a positive foil with a positive guide pin riveted and a negative foil with a negative guide pin riveted, which are laid in electrolytic paper between the two foils, and the negative foil of the aluminum ...
