Aluminum electrolytic capacitor making process

Abstract

This invention relates to a manufacturing method for Al electrolyte condensers including: connecting the tongue parts of positive and negative conducting pins with positive and negative foils by riveting and putting the front parts of the initially processed anode and cathode foils at a cylindrical shaft together characterizing in adding two layers of electrolyte paper a and c between the foils and putting the front parts of them at the shaft, adding two layers of electrolyte paper b and d between the cathode foil and an anti-loose adhesive tape and putting the front parts of them at the shaft, starting up the switch of the shaft to wind the anode and cathode foils and electrolyte paper a, b, c and d along with the shaft then to bind them with the anti-loose tape, then dipping them to put them into a tubular Al shell with bottom and sealing the open of the Al shell with rubber plug to get an Al electrolyte condenser.

Description

technical field [0001] The invention relates to a manufacturing process of an aluminum electrolytic capacitor, belonging to the technical field of capacitor manufacturing technology. Background technique [0002] At present, in the existing aluminum electrolytic capacitor production process, the tongues of the positive and negative guide pins are riveted on the positive and negative aluminum foils. Since there is only a layer of electrolytic paper between the positive and negative aluminum foils, the positive foil guide pin tongues The burr on the part of the electrolytic paper is in contact with the electrolytic paper, and the burr may pierce the electrolytic paper and cause a short-circuit breakdown; the positive electrode foil and the tongue of the guide pin are connected by rivets. When the power is applied, an electrochemical reaction will occur at this place and generate a lot of heat, resulting in product failure. Shortened lifespan. Contents of the invention [00...

[0002] At present, in the existing aluminum electrolytic capacitor production process, the tongues of the positive and negative guide pins are riveted on the positive and negative aluminum foils. Since the positive and negative aluminum foils are only separated by a layer of electrolytic paper, the positive foil guide pin tongues The burr on the part of the electrolytic paper is in contact with the electrolytic paper, and the burr may pierce the electrolytic paper and cause a short-circuit breakdown; the positive electrode foil and the tongue of the guide pin are connected by rivets. When the power is applied, an electrochemical reaction will occur at this place and a large amount of heat will be generated, resulting in product failure. shortened lifespan
