  Elektrischer Kondensator, dessen Dielektrikum aus einer Oxydschicht besteht, insbesondere Elektrolyt- kondensator. 



   Bei der Herstellung elektrischer Kondensatoren, deren Dielektrikum aus einer auf den Elektroden erzeugten Oxydschicht besteht, wie bei den bekannten   Elektrolytkondensatoren,   lässt es sich nicht immer vermeiden, dass nach der Erzeugung der Oxydschicht diese durch die weitere Verarbeitung an einigen
Stellen wieder entfernt oder beschädigt wird. Z. B. kommt es oft vor, dass nach dem Formieren Teile von der Anode abgeschnitten werden müssen und dadurch wieder blanke unformierte Stellen entstehen. 



  Ausserdem müssen die Stellen der Anschlussfahne, die unter einen   Anschlussbolzen   geklemmt werden, zur Erzielung eines guten Kontaktes ebenfalls blank bleiben. Es besteht also in diesen Fällen die Gefahr, dass, wenn Elektrolyt aus dem Kondensator an die blanken Stellen gelangt, ein   Nebenschluss   hergestellt, und der Fehlerstrom des Kondensators vergrössert wird. 



   Zur Vermeidung dieser Nachteile werden nach der Neuerung alle mit den oxydierten Belegungen in Verbindung stehenden Metallteile an den blanken Stellen mit einer unmittelbar anliegenden Isolierschicht, z. B. mit einem Lacküberzug versehen. Ein solcher Lacküberzug verhindert also dem Elektrolyt den Zutritt zu diesen Stellen und damit das Ansteigen des   Fehlerstromes.   



   In der Zeichnung ist ein Ausführungsbeispiel eines derartigen Kondensators dargestellt, bei dem die Schnittkanten 1 der oxydierten Elektrode und die blanken Teile 2 der   Anschlussfahne   mit einer Lackschicht 3 und 4 überzogen sind. Das Gehäuse besteht aus einem Metallbecher 5, der durch einen Deckel 6 aus roher Pappe verschlossen ist.

  Electrical capacitor, the dielectric of which consists of an oxide layer, in particular an electrolytic capacitor.



   In the manufacture of electrical capacitors, the dielectric of which consists of an oxide layer produced on the electrodes, as is the case with the known electrolytic capacitors, it cannot always be avoided that, after the oxide layer has been produced, it becomes unified by further processing
Places again removed or damaged. For example, it often happens that, after forming, parts have to be cut off from the anode, resulting in blank, unformed areas again.



  In addition, the points of the connection lug that are clamped under a connection bolt must also remain bare in order to achieve good contact. In these cases there is therefore the risk that if the electrolyte gets from the capacitor to the bare areas, a shunt is established and the fault current of the capacitor is increased.



   To avoid these disadvantages, according to the innovation, all metal parts in connection with the oxidized coverings are provided with an immediately adjacent insulating layer, e.g. B. provided with a varnish coating. Such a lacquer coating prevents the electrolyte from accessing these points and thus the increase in the fault current.



   The drawing shows an exemplary embodiment of such a capacitor in which the cut edges 1 of the oxidized electrode and the bare parts 2 of the terminal lug are coated with a layer of lacquer 3 and 4. The housing consists of a metal cup 5 which is closed by a cover 6 made of raw cardboard.
