Description
Elektrolytkondensator.Electrolytic capacitor.
Die Neuerung bezieht sich auf einen Elektrolytkondensator, bei dem die Anode durch einen Sinterkörper, vorzugsweise aus Tantal, gebildet wird.The innovation relates to an electrolytic capacitor in which the anode is formed by a sintered body, preferably made of tantalum.
Es ist bereits"bekannt, zur Erzielung einer grossen Kapazität auf
kleinem Raum als Anode in elektrolytischen Kondensatoren Sinterkörper aus Ventilmetall
zu verwenden- Hierbei ist es wichtige dass einerseits der Sinterkörper vollkommen
in den Elektrolyten eintaucht, damit dessen ganze Oberfläche zur Kapazitätsbildung
ausgenützt wird, und dass andererseits die. mit dem Elektrolyten
Man hat daher vorgeschlagen, diese Stelle besonders durch iso-
Gemäss der weiteren Ausbildung der Neuerung wird der Sinterkorper durch schwammartige Zwischenlagen, die gegen den Elektrolyten unempfindlich sein müssen, im Gehäuse unbeweglich festgelegt.According to the further development of the innovation, the sintered body through sponge-like intermediate layers that are insensitive to the electrolyte must be fixed immovably in the housing.
Durch die zahlreichen Poren der Zwischenlagen kann der Elektrolyt
von allen Seiten zum Sinterkörper gelangen. Derartige Zwischen-
Der Kondensator 1, der die Kathode bildet, besteht aus einem geeigneten,
gegen den Elektrolyten inorten Metall. So wird für Kondensatoren mit Aluminiumanodc
vorzugsweise ein Becher aus Aluminium verwendet, für Kondensatoren mit Tantalanode
ein Becher aus reinem Silber. Der Becher trägt an einer geeigneten Stelle eine elektrische
Zuleitung 7, die beispielsweise durch Anlöten, wie dies bei 8 angedeutet ist, mit
dem Becher 1 verbunden ist. Der Becher kann aber auch schon bei seiner Herstellung
mit einem entsprechenden Ansatz vorsehen worden, der als Zuleitung dienen kann.
Der Becher ist durch eine Platte 3 aus
lötfähigem M@tall abgeschlossen,
die an ihrer Innenseite
Auf diese Weise werden durch die Neuerung die erwähnten Schwierigkeiten
des Anodenanschlusscs vermieden* Die Kondensatoren sind einfach und billig herzustellen
und robust im Betrieb.
