Abstract
The utility model relates to the capacitor technical field, in particular to an aluminum electrolytic capacitor which comprises an aluminum shell, an anode foil guide pin, a cathode foil guide pin, an anode foil, a cathode foil and at least two electrolytic paper layers, wherein the anode foil guide pin, the cathode foil guide pin, the anode foil, the cathode foil and the electrolytic papers are disposed in the aluminum shell. The electrolytic paper disposed between the anode foil and the cathode foil is rolled into a cylindrical core, the anode foil guide pin and the cathode foil guide pin are formed via 1-700V formation voltage, one end of the formed anode foil guide pin is riveted with the anode foil while the other end extends out of the top of the aluminum shell, and one end of the formed cathode foil guide pin is riveted with the cathode foil while the other end extends out of the top of the aluminum shell. After the anode foil guide pin and the cathode foil guide pin are formed via 1-700V formation voltage, breakdown of riveted joints among the anode foil guide pin, the cathode foil guide pin, the anode foil and the cathode foil can be avoided, thereby prolonging the service life of the aluminum electrolytic capacitor.
