Description
Kondensatorwickel für Elektrolytkondensatoren Gegenstand der Erfindung ist die Verbesserung des Abschlusses von Kondensatorrohwickeln nach der Fertigstellung auf einer Wickelmaschine oder einem Wickelautomaten. Es ist bekannt, die Kondensatorwickel mit Hilfe von Banderolen (Klebebändern, Drähten od. dgl.) oder aus Metall bestehenden Schließbändern abzuschließen. Damit war zwar ein einfacher und zuverlässiger Wickelabschluß erreichbar. aber alle diese Maßnahmen führten im Betrieb zu einer vorzeitigen und allmählich untragbar werdenden Verschlechterung und schließlich zur Zerstörung des Kondensators. Bei statischen Kondensatoren ist es andererseits bekannt, als äußere Lagen zwei oder mehr Windungen einer als Belegung bzw. als Stromzuführung jeweils verwendeten Metallfolie aufzubringen, wobei die letzte Windung auf der vorangegangenen Windung durch Löten festgelegt wird. Schließlich hat man auch schon bei Elektrolytkondensatoren die Kathodenfolie um den Wickel herumgelegt und mittels eines Metallringes und eines Isolierpfropfens fest gegen die Wand des Metallgebäuses gepreßt. Nach eingehenden Untersuchungen ergab sich, daß die bekannten Wickelabschlußmaßnahmen zur Korrosion auf der Mantelfläche des Kondensatorwickels und/oder zur Verschlechterung des Elektrolyten führen (Einwirkung der Klebe- oder Lötmittel, Fingerabdrücke beim Verdrillen der Drähte oder beim Falten der Schließbänder und sonstiger Verunreinigungen).Capacitor winding for electrolytic capacitors is the subject of the invention is the improvement of the completion of condenser coils after completion on a winding machine or an automatic winding machine. It is known the capacitor winding with the help of banderoles (adhesive tapes, wires or the like) or made of metal Complete closing straps. This was a simple and reliable wrap closure accessible. but all these measures led to premature and in operation gradually deteriorating and ultimately destructive of the unsustainable Capacitor. In the case of static capacitors, on the other hand, it is known as external Lay two or more turns of one as an occupancy or as a power supply in each case used metal foil to apply, with the last turn on the previous one Winding is set by soldering. After all, you also have electrolytic capacitors the cathode foil wrapped around the winding and by means of a metal ring and a Isolation plug firmly pressed against the wall of the metal housing. After incoming Investigations showed that the known winding termination measures lead to corrosion on the outer surface of the capacitor winding and / or to deteriorate the electrolyte lead (exposure to adhesives or solder, fingerprints when twisting the Wires or when folding the fastening straps and other impurities).
Bei dem Kondensator nach der Erfindung wird die Gefahr, daß zur Korrosion neigende oder überhaupt auf den Kondensator, insbesondere auf den Elektrolyten ungünstig einwirkende Fremdstoffe eingebracht werden, weitgehend ausgeschaltet. Bei einem Kondensatorwickel für Elektrolytkondensatoren, bei dem als äußere Lagen zwei oder mehrere Windungen einer Kathodenfolie aufgebracht sind. besteht die Erfindung darin, daß die letzte Windung auf der vorangegangenen Windung durch Schweißen, vorzugsweise unter Verwendung von Schweißelektroden aus Ventilmetall, wie z. B. Tantal, festgelegt ist.In the capacitor according to the invention, there is a risk of corrosion tending or unfavorable at all on the capacitor, especially on the electrolyte influencing foreign substances are introduced, largely eliminated. At a Capacitor winding for electrolytic capacitors with two or two outer layers several turns of a cathode foil are applied. the invention consists in that the last turn on the previous turn by welding, preferably using welding electrodes made of valve metal, e.g. B. tantalum, set is.
Die zu dieser Kondensatorfolie gehörige Anschlußfahne kann entweder auf die gleiche Art mit dem Wickelabschluß zusammen oder getrennt davon angeschweißt oder angefaltet oder angeschnitten werden.The terminal lug belonging to this capacitor film can either welded together or separately to the end of the winding in the same way or be folded or cut.
Durch das Schweißen und die Verwendung von Schweißelektroden aus Ventilmetall, wie z. B. Tantal, wird erreicht, daß keine schädlichen Fremdstoffe auf den Kondensatorwickel und in den Elektrolyten gebracht werden.By welding and using welding electrodes made of valve metal, such as B. tantalum, it is achieved that no harmful foreign matter on the capacitor winding and placed in the electrolyte.
