Description

Elektrode für nassen elektrolytischen Kondensator Die Erfindung betrifft eine Elektrode für einen. nassen elektrolytischen Kondensator, die aus mehrfach scharf gefaltetem Blech besteht, das um einen Mittelträger angeordnet ist und dessen Falten ungefähr senkrecht zu dem Mittelträger nach außen gerichtet sind, die im übrigen aber frei tragend und ausreichend steif sind.Electrode for Wet Electrolytic Capacitor The invention relates to one electrode for one. wet electrolytic capacitor made up several times sharply folded sheet metal, which is arranged around a central beam and its Folds are directed outwards approximately perpendicular to the central beam, which in the but the rest are self-supporting and sufficiently rigid.

Gemäß der Erfindung verlaufen die Scheitellinien parallel zum Träger, und gleichzeitig sind die innenliegenden Scheitellinien, am Mittelträger befestigt.According to the invention, the vertex lines run parallel to the beam, and at the same time the apex lines on the inside are attached to the central beam.

Elektrolytkondensatoren mit gefalteten Blechen als Elektrode sind bekannt. Sie weisen alle den Nachteil auf, daß die Falten nicht an den innenliegenden Scheitellinien im Träger befestigt sind, wodurch ein sehr labiles Elektro@dengebilde entsteht. Insbesondere können odie Bleche aneinander reiben, wenn der Kondensator transportiert wird oder im Betrieb Erschütterungen unterliegt. Hierdurch kann die dielektrische Schicht an dem Blech, falls es die Anode bildet, beschädigt und auf jeden Fall Teile der Elektrode kurzgeschlossen werden. Solche Kondensatoren sind also keinesfalls. betriebssicher, es sei denn, daß die Elektrode aus so steifem Blech hergestellt oder gar aus einem Metallstück herausgearbeitet wird, daß die frei tragenden Teile ihre Form ohne weiteres beibehalten. Solch dickes Blech ist aber schwer und teuer, und dies gilt in weit höherem Maße für aus dem vollen herausgearbeitete oder aus Metall gepreßte Elektroden.Electrolytic capacitors with folded sheets as an electrode are known. They all have the disadvantage that the folds are not on the inside Vertex lines are attached in the carrier, creating a very unstable electrode structure arises. In particular, the sheets can rub against one another when the capacitor is transported or is subject to vibrations during operation. This allows the dielectric layer on the sheet, if it forms the anode, damaged and on parts of the electrode are short-circuited. Such capacitors are so by no means. safe to operate unless the electrode is made so stiff Sheet metal is made or even worked out from a piece of metal that the Cantilever parts retain their shape easily. Such thick Sheet metal, however, is heavy and expensive, and this applies to a far greater extent to from the electrodes machined or pressed from metal.

Weiterhin sind durch Ziehen, Pressen u. dgl. hergestellte Elektroden bekanntgeworden, bei denen um einen Mittelträger herum angeordnete längere Rippen od. dgl. vorhanden sind. Gegenüber der gekennzeichneten Anordnung, bei der beide Seiten der gefalteten Bleche Kapazität bilden, ist bei dieser bekannten Anordnung mit geringerer Kapazitätsausbeute zu rechnen.Furthermore, electrodes produced by drawing, pressing and the like are produced became known, in which arranged around a central beam around longer ribs or the like. Are present. Compared to the marked arrangement in which both Sides of the folded sheets forming capacitance is in this known arrangement with a lower capacity yield to be expected.

Es wurde auch vorgeschlagen, das Blech der Elektrode in Windungen zu legen; dann war es aber erforderlich. die Windungen voneinander durch Sonderausbildungen in Abstand zu halten. War die Elektrode als Anode ausgebildet, so konnten die Abstandhalter wiederum die dielektrische Schicht abreiben und verletzen.It has also been proposed to turn the sheet metal of the electrode into turns to lay; but then it was necessary. the turns of each other through special training to keep at a distance. If the electrode was designed as an anode, the spacers could in turn rub off and damage the dielectric layer.

Das Blech der Elektrode braucht bei der hier gekennzeichneten Anordnung keinesfalls auch nur annähernd gleiche Steifigkeit zu besitzen wie ein Blech, das in frei tragenden Falten oder Windungen angeordnet ist, wobei die Windungen einfach liegen und die Falten von einem Träger ausgehen und nicht jede derselben entlang der Scheitellinie gefaßt ist* Ist nämlich jede Falte an ihrer Scheitellinie am Mittelträger befestigt, dann «erden zwei nahe aneinanderliegende Wände gebildet, deren Festigkeit und Steifigkeit zusammenwirken.The sheet metal of the electrode is required in the arrangement shown here by no means to have even approximately the same rigidity as a sheet metal, the is arranged in cantilever folds or turns, the turns simple lie and the folds emanate from a carrier and not along each of them the apex line is grasped * is every fold at its apex line on the central beam attached, then «ground two closely spaced walls, whose strength and rigidity work together.
