Abstract

The capacitor cup has a cylindrical wall (2) with a restriction (8) formed in the cup bottom (3) and above the restriction the cup wall contains an outer bead (4). Preferably the shrinking tube (1) end in the restriction of the cup wall, and the capacitor is secured by the outer bead and an overthrow ring by threads at the capacitor support. A heat conductive foil (6) is pressed against the cup bottom by screwing the overthrow ring to the capacitor support.

Description

Die Erfindung betrifft die Becher-Form von Elektrolyt­ kondensatoren.The invention relates to the cup form of electrolyte capacitors.

Es ist bekannt, daß beim Betrieb von Elektrolytkonden­ satoren Wärme entsteht, die durch überlagerten Wechsel­ strom, bedingt durch dielektrische Verluste, hervorgerufen wird. Die Wärme setzt die Dauer der Brauchbarkeit des Kondensators erheblich herab und ist daher schädlich.It is known that when operating electrolytic condensers heat generated by superimposed change current caused by dielectric losses becomes. The heat sets the duration of the usability of the Capacitor down considerably and is therefore harmful.

Es ist daher Aufgabe der Erfindung, eine gute Wärmeablei­ tung bei Becher-Elektrolytkondensatoren herbeizuführen.It is therefore an object of the invention to provide good heat dissipation induction with cup electrolytic capacitors.

Diese Aufgabe wird nach der Erfindung dadurch gelöst, daß die zylindrische Wandung des Bechers 2 an dessen Boden 3 eine Einziehung 8 aufweist.This object is achieved according to the invention in that the cylindrical wall of the cup 2 has a recess 8 on the bottom 3 thereof.

Nach einer weiteren Ausführungsform kann die Becherwand 2 oberhalb der Einziehung 8 eine Außensicke 4 aufweisen.According to a further embodiment, the cup wall 2 is an external bead 4 can have above the recovery. 8

Um den Schrumpfschlauch 1, welcher in der Einziehung B der Becherwand 2 endet, festzulegen, kann ein Überwurfring 5 vorgesehen sein, welcher an der Außensicke 4 aufliegt und durch Verschraubungen 7, 7' und 9, 9' an der Kondensa­ torauflage 10 angeschraubt wird. In order to fix the shrink tube 1 , which ends in the indentation B of the cup wall 2 , a coupling ring 5 can be provided which rests on the outer bead 4 and is screwed onto the capacitor support 10 by screw connections 7 , 7 'and 9 , 9 '.

Mittels der Verschraubungen 7, 7' und 9, 9' kann die Wärmeleitfolie 6, welche auf dem Becherboden 3 aufliegt, vorteilhaft an diesen angepreßt werden.By means of the screw connections 7 , 7 'and 9 , 9 ', the heat-conducting film 6 , which rests on the cup base 3 , can advantageously be pressed onto the latter.

In der anliegenden Zeichnung sind Ausführungsbeispiele von Elektrolytkondensatoren dargestellt und werden im folgenden näher beschrieben.In the accompanying drawing are exemplary embodiments of Electrolytic capacitors are shown and are shown below described in more detail.

In der Zeichnung ist der zylindrische Teil des Aluminiumbechers mit 2 bezeichnet, welcher im allgemeinen - mit einem Wickel aus Elektrolytträger und Aluminiumfolie gefüllt - den Elektrolytkondensator bildet. Zur Außen­ isolierung ist die zylindrische Wand des Bechers 2 mit einem Schrumpfschlauch 1 aus PVC umgeben. Der Becherboden 3 des Kondensators aus Aluminium liegt entsprechend Fig. 1 bis 3 frei. Von ihm wird die im Kondensator entstehende Wärme über eine Wärmeleitfolie 6 nach außen abgeleitet. Bei Aufstellung des Kondensators auf einem offenen Geste 11 kann entstandene Wärme durch einen vorbei-streichenden Luftstrom gekühlt werden.In the drawing, the cylindrical part of the aluminum cup is denoted by 2, which generally forms the electrolytic capacitor, filled with a coil made of electrolyte carrier and aluminum foil. For external insulation, the cylindrical wall of the cup 2 is surrounded by a shrink tube 1 made of PVC. The cup bottom 3 of the aluminum capacitor is exposed according to FIGS . 1 to 3. From him, the heat generated in the condenser is dissipated to the outside via a heat-conducting film 6 . When the condenser is placed on an open gesture 11 , the heat generated can be cooled by a passing air stream.

Nach einer weiteren Ausführungsform der Erfindung ist der zylindrische Teil des Bechers 2 mit einer Außensicke 4 ver­ sehen. Der Schrumpfschlauch 1 reicht über die Außensicke 4 bis an die Einziehung 8 vor dem Becherboden 3 hinweg; er kann mittels eines Überwurfringes 5 an der Außensicke 4 festgelegt werden. Der Überwurfring 5, der mittels Verschraubungen 7, 7' und 9, 9' an der Auflagefläche das Kondensators 10 festgeschraubt wird, dient ferner dazu, die Wärmeleitfolie 6 durch die Auflagefläche 10 an den Becher­ boden 3 anzupressen.According to a further embodiment of the invention, the cylindrical part of the cup 2 is seen with an external bead 4 . The shrink tube 1 extends beyond the outer bead 4 to the indentation 8 in front of the cup bottom 3 ; it can be fixed on the outer bead 4 by means of a collar ring 5 . The collar 5, which is screwed by means of screw connections 7, 7 'and 9, 9' to the support surface, the capacitor 10 further serves the thermally conducting floor 6 by the support surface 10 on the cup to be pressed. 3
