Aluminum electrolytic capacitor and process of producing the same |
摘要 |
There is provided an aluminum electrolytic capacitor including a hollow capacitor element composed of an anode foil, a cathode foil each with an extracted lead member connected thereto, and a separator between both the foil wound into a coil, an end face of the cathode foil is projected relative to the corresponding face of the anode foil; a elastic sheet which is wound on the periphery of the capacitor element; a cylindrical metallic case having the bottom in which a fixing rod is projected on the center of the bottom for fitting into a hollow hole part of the capacitor element and one or more fixing ribs are provided on the bottom for abutting with the projected end face of the cathode foil; and a sealing plate for covering the upper opening of the metal case which has a pair of terminals formed passing through the sealing plate for connecting to extracted lead member of the capacitor element and a threaded portion for external connection; wherein the metal case has one or more annular extrusions projected inside around the case; the capacitor element is housed in the case with an electrolyte with the upper opening of the case being sealed with the sealing plate via an O-ring around the periphery of the sealing plate; and the capacitor element is partly fixed via the elastic sheet by the one or more annular protrusions inside the metal case.
