Solid electrolytic capacitor equiped with an opening mechanism

Abstract

In order to prevent an incorporated fuse in a solid electrolyte capacitor from being disconnected by mechanical stress after the attachment thereof and to maximize the capacity of the fuse-incorporated capacitor element by reducing the space for attachment of the fuse; a solid electrolyte capacitor equipped with an opening mechanism is structured in a manner such that a fuse connecting portion is constructed by a three layered structure in which an insulator is sandwiched between an anode terminal and a metal piece connected to an anode lead terminal, and a fuse is disposed in a cross-linking manner between the metal piece and the anode lead terminal. With this arrangement, according to the present inveniton, it is possible to prevent the fuse from being broken or disconnected from the connecting portions by mechanical impacts after connection of the incorporated fuse. Furthermore, it is possible to minimize the space for the attachment of the fuse, and thus fuse-incorporated capacitor element can be maximized in its capacity.
