Abstract
The utility model discloses an aluminium electrolytic capacitor, comprising a capacitor core. The capacitor core consists of an anode metal foil, a cathode metal foil, an anode guide pin, and a cathode guide pin. The anode guide pin is riveted with the anode metal foil. The cathode guide pin is riveted with the cathode metal foil. At least one layer of electrolytic paper is clamped between the anode metal foil and the cathode metal foil. The back surfaces of the anode metal foil and the cathode metal foil are each provided with a layer of pad paper. The two layers of pad paper respectively cover burrs formed by the riveting of the anode guide pin and the anode metal foil and burrs formed by the riveting of the cathode guide pin and the cathode metal foil. The cathode metal foil employs a corrosive energized aluminium foil with an energized voltage ranging from 1 V to 160 V. The pad paper of the aluminium electrolytic capacitor can block off the burrs and prevent the defects that the burrs can penetrate through the electrolytic paper or the point discharge of the burrs in an electric field can cause the capacitor to short out, break down, or explode. Besides, the cathode metal foil is strong in ripple-resistant property and capable of bearing the impact from reverse direction leakage current and effectively prolonging the service life of the aluminium electrolytic capacitor.
