Description
Elektrolytischer Kondensator, dessen Gehäuse durch eine Deckschicht aus Vergußmasse abgeschlossen ist, durch welche die mit der Belegung verbundenen Zwischenleitungen geführt sind Die Erfindung bezieht sich auf Elektrolytkondensatoren. Bei diesen ist es bekanntlich schwierig, die Belegungen mit den Anschlußleitungen betriebssicher zu verbinden, -da die Verbindungsstelle zwischen Belegung und Anschlußleitung durch die Einwirkung des Elektrolyten leicht korrodiert und infolgedessen zerstört wird.Electrolytic capacitor, the housing of which is covered by a top layer from potting compound is completed, through which the associated with the occupancy Intermediate lines are guided The invention relates to electrolytic capacitors. With these it is known to be difficult, the assignments with the connecting lines to connect reliably because the connection point between occupancy and connection line easily corroded by the action of the electrolyte and consequently destroyed will.
Es ist bereits bekannt, den Kondensator durch eine Deckschicht aus Vergußmasse abzuschließen. Durch diese Schicht werden Verbindungsstücke oder hochgebogene Teile der Belegungen selbst geführt, die oberhalb der Deckschicht mit den. -eigentlichen Anschlußleitungen verbunden werden.It is already known that the capacitor is made up of a top layer Complete potting compound. Through this layer connecting pieces or bent up Parts of the assignments even performed, the above the top layer with the. -actual Connection lines are connected.
Die Praxis hat gezeigt, cdaß es sich. bei einer solchen Ausführung -nicht verhindern läßt, daß in feinsten Kapillarröhren Elektrolytflüssigkeit an den durch die Vergußmasse durchgeführten Leitungsteilen entlang aufsteigt. Dies ist unter anderem auf den unvermeidbaren Schwund der Vergußmasse .beim Erhärten zurückzuführen. .Außerdem wird diese Erscheinung dadurch unterstützt, daß die Vergußmasse warm eingefüllt wird und den sich hierdurch ausdehnenden Elektrolyten hochtreibt. Sobald die Elektrolytflüssigkeit an die Verbindungsstellen zwischen den hochgebogenen Teilen der Belegung bzw. den Zwischenstücken und den eigentlichen Anschlußleitungen gelangt, erfolgt Korrosion und damit eine allmähliche Zerstörung der Verbindungsstellen.Practice has shown that it is. in such an execution - does not prevent electrolyte fluid from accumulating in the finest capillary tubes rises along the line parts passed through the potting compound. this is among other things on the inevitable shrinkage of the casting compound .beim hardening traced back. In addition, this phenomenon is supported by the fact that the casting compound is filled in warm and pushes up the electrolyte that expands as a result. As soon as the electrolyte fluid reaches the joints between the bent up Share the assignment or the spacers and the actual connecting lines corrosion occurs and the joints are gradually destroyed.
Es ist weiterhin bekannt, die Verbindungsstelle in die Deckschicht hineinzuverlegen. Auch bei einer solchen Ausführung kann aus den gleichen Gründen, wie vorstehend erläutert, ohne weiteres Elektrolytflüssigkeit zu den Verbindungsstellen gelangen und hier eine Korrosion verursachen.It is also known that the connection point in the top layer to relocate. Even with such a design, for the same reasons, as explained above, without further electrolyte fluid to the connection points and cause corrosion here.
Gemäß der Erfindung wird nun eine technisch dauernd einwandfreie Verbindung da:-durch erreicht, daß die Verbindungsstellen der Zwischenleitungen mit den eigentlichen Anschlußleitungen in der Grenzfläche zwischen der das Gehäuse abschließenden Deckschicht und einer zweiten Deckschicht aus Vergußmasse angeordnet sind. Durch diese obere Deckschicht wird der Kondensator praktisch vollkommen dicht abgeschlossen, da die zweite Deckschicht erst dann aufgegossen wird, wenn die untere erkaltet ist. Infolgedessen wird der Elektrolyt nicht mehr erwärmt, so daß er bei der oberen Deckschicht nicht wie bei der unteren die Möglichkeit .hat, in Kapillaren an den Leitungsdrähten entlang aufzusteigen.According to the invention, there is now a technically permanently flawless connection da: -by achieved that the connection points of the intermediate lines with the actual Connection lines in the interface between the cover layer closing off the housing and a second cover layer of potting compound are arranged. Through this upper one The top layer of the capacitor is practically completely sealed, since the second top layer is not poured on until the lower one has cooled down. Consequently the electrolyte is no longer heated, so that it is not at the top cover layer as with the lower one, has the option of running along the lead wires in capillaries to ascend.
In der beiliegenden Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt.In the accompanying drawing is an embodiment of the invention shown.
r ist das Kondensatorgehäuse, 2 die Belegungen. Von diesen Belegungen, die im allgemeinen aus Aluminium bestehen, werden an geeigneter Stelle zwei Streifen 3, 4. hochgebogen, die die Anschlußleitungen bilden. Durch eine Deckschicht 5 aus Vergußmasse wird das Gehäuse abgeschlossen. Mit den über die untere Deckschicht 5 herausragenden Streifen 3,4 werden die- z. B. aus Kupferdraht bestehenden, Anschlußleitungen 6, 7 verbunden, dann wird die obere Deckschicht 8 aufgegossen.-- Zweckmäßig benutz: man für die untere Deckschicht eine Verguß: masse mit einem niedrigeren Schmelzpurf; als ihn die Vergußmasse der oberen Schic'hW._ besitzt.r is the capacitor housing, 2 the assignments. Of these assignments, which are generally made of aluminum, become two strips at a suitable point 3, 4. bent up, which form the connecting lines. Through a cover layer 5 from The housing is sealed off with potting compound. With the over the lower top layer 5 outstanding Stripes 3.4 are the z. B. made of copper wire existing, connecting lines 6, 7 are connected, then the upper cover layer 8 poured on .-- Expediently used: one potting compound for the lower top layer with a lower melting track; when the potting compound of the upper Schic'hW._ owns.
Durch die vorstehend beschriebene Herausführung der Leitungsteile wird .es auch ermöglicht, die mechanisch wenig widerstandsfähigen, aber korrosionsfreien Streifen 3, 4 sicher mit den festen Anschlußdrähten :6, 7 zu verbinden, ohne Gefahr zu laufen, daß die Verbindungsstellen sowie die ganzen Anschlußleitungen durch Korrosion allmählich zerstört werden.By leading out the line parts as described above it is also possible to use the mechanically less resistant, but corrosion-free Strips 3, 4 can be securely connected to the fixed connection wires: 6, 7 without danger to run that the connection points as well as all the connecting lines by corrosion to be gradually destroyed.
