Description
Verfahren zur Herstellung von Schicht- oder Wickelkondensatoren Die Erfindung bezieht sich auf ein Verfahren zur Herstellung von Schicht- oder Wickelkondensatoren, bei dem der Kondensatorkörper durch Schneiden bearbeitet wird und dann die an die Schnittflächen angrenzenden Teile der Belegungen so weit zerstört werden, daß die Schnittflächen keine den Betrieb des Kondensators störende Leitfähigkeit mehr haben. Die Entfernung der Metallschichten an den Schnittflächen kann in der Praxis insbesondere auf chemisch-elektrolytischem Wege vorgenommen werden. Als in gewisser Beziehung nachteilig muß jedoch bei diesem Verfahren in Kauf genommen werden, daß es verhältnismäßig lange zeit und große Sorgfalt beansprucht. Außerdem kann bei allen Verfahren, die mit wäßrigen Lösungen arbeiten, das Dielektrikum, insbesondere wenn es aus Papier besteht, leicht quellen, wodurch der Kondensator unter Umständen seinen Zusammenhang verliert.Process for the production of film or wound capacitors Die The invention relates to a method for the production of film or wound capacitors, in which the capacitor body is processed by cutting and then the to the Cut surfaces adjacent parts of the assignments are destroyed to such an extent that the Cut surfaces no longer have conductivity that would interfere with the operation of the capacitor. The removal of the metal layers at the cut surfaces can in particular in practice be carried out by chemical-electrolytic means. As in some way However, the disadvantage of this method is that it is proportionate demanded a long time and great care. In addition, in all procedures that work with aqueous solutions, the dielectric, especially if it is made of paper exists, swell slightly, whereby the capacitor may be connected loses.
Gemäß der Erfindung werden die aus einer bei Erwärmung durch Inselbildung ihre Leitfähigkeit verlierenden Metallschicht bestehenden Belegungen an den Schnittflächen auf die für die Inselbildung der Metallschichten nötige Temperatur erwärmt. Metallschichten mit dieser Eigenschaft werden aus Metallen mit möglichst niedrigem Schmelzpunkt, z. B. aus dem Kadmium-Zink-Eutektikum, gebildet. Erwärmt man diese Schichten auf die entsprechende Temperatur, so zieht das Metall sich in nicht miteinander zusammenhängende Inseln zusammen, so daß die Leitfähigkeit solcher Schichten dadurch zerstört ist.According to the invention, they are made of a when heated by island formation Metal layers on the cut surfaces that lose their conductivity heated to the temperature necessary for the formation of islands in the metal layers. Metal layers With this property, metals with the lowest possible melting point z. B. from the cadmium-zinc eutectic formed. If you warm up these layers the corresponding temperature, the metal pulls itself into non-contiguous Islands together, so that the conductivity of such layers is destroyed.
Das erfindungsgemäße Verfahren läßt sich in einfacher Weise dadurch durchführen, daß der Kondensatorkörper nach dem Bearbeiten durch Schneiden mit seinen Schnittflächen auf eine beheizte Fläche aufgesetzt wird. Dadurch ziehen sich die Belegungsteile an den Schnittflächen in kürzester Zeit zu Klümpchen oder Inseln zusammen, und die Schnittflächen erhalten ihren erforderlichen Isolationswert. Die Einwirkung der beheizten Fläche auf die Schnittflächen braucht dabei nur so kurzzeitig zu sein, daß das als Dielektrikum verwendete Kondensatorpapier durch die Temperatur der Heizfläche keinen Schaden erleidet. Auch Dielektrika aus anderen Stoffen sind für dieses Verfahren geeignet. Mit dem neuen Verfahren kann die erforderliche Zerstörung der Belegungen an den Schnittflächen sehr rasch erzielt werden, ohne daß irgendeine Schädigung des Kondensatorblocks in Kauf genommen werden müßte.The method according to the invention can be carried out in a simple manner perform that the capacitor body after machining by cutting with his Cut surfaces is placed on a heated surface. This causes the Allocation parts on the cut surfaces to lumps or islands in the shortest possible time together, and the cut surfaces get their required insulation value. the The heated surface only needs to act for a short time on the cut surfaces to be that the capacitor paper used as a dielectric by temperature the heating surface is not damaged. Also dielectrics made from other substances are suitable for this procedure. With the new process, the required destruction can the coatings on the cut surfaces can be achieved very quickly without any Damage to the capacitor block would have to be accepted.
Zur Durchführung des Verfahrens werden zweckmäßig die Kondensatoren nach der Bearbeitung durch Schneiden mit ihren Schnittflächen kurzzeitig auf eine geheizte Platte aufgesetzt.The capacitors are expediently used to carry out the process after processing by cutting with their cut surfaces briefly on a heated plate put on.
