Description
Elektrischer Kondensator aus mehreren geschichteten Einheitslamellen aus Aluminiumblättchen Es ist bekannt, geschichtete Kondensatoren aus in Reihe geschalteten einzelnen Elementen dadurch auszubilden, daß zwischen °den Isolierschichten, z. B. aus Glimmer oder einem anderen Isolierstoff, blindverlegte Metallfolien eingefügt oder Metallschichten durch Metallisierungentsprechender Oberflächenteile der dielektrischen Lamellen gebildet sind. Sollten derartige Kondensatoren eine große ,Spannung aushalten können, so zog man bis jetzt vor, als Isolierwerkstoff Glimmer zu verwenden.Electric capacitor made of several layered unit fins From aluminum flakes It is known to make layered capacitors from series-connected to train individual elements that between ° the insulating layers, for. B. made of mica or another insulating material, blind laid metal foils inserted or metal layers by metallizing corresponding surface parts of the dielectric Lamellae are formed. Such capacitors should withstand a large voltage up until now it was preferred to use mica as an insulating material.
Weiter ist @es bekannt, einen Kondensator herzustellen, bei dem die Belegung aus Aluminium, das Dielektrikum, aus einer auf der Aluminiumbelegung gebildeten Oxydschicht besteht. Bei der Herstellung eines solchen Kondensators, dessen Aluminiumbelegung nur teilweise oxydiert ist, besteht der Nachteil, daß von der Belegung bestimmte Teile abgedeclrt werden müssen, was erforderlich ist, um den elektrischen Anschluß für die Aluminiumfolie zu erhalten.It is also known to produce a capacitor in which the Allocation made of aluminum, the dielectric, from a layer formed on the aluminum There is an oxide layer. When manufacturing such a capacitor, its aluminum coating is only partially oxidized, there is the disadvantage that it is determined by the occupancy Parts must be covered off what is required to make the electrical connection for the aluminum foil to get.
Die Erfindung betrifft nun einen elektrischen Kondensator aus mehreren geschichteten Einheitslamellen aus Aluminiumblättchen, die mit als Dielektrikum dienender Aluminiumoxydschicht versehen sind. Die Verwendung von Glimmer wird entbehrlich und der Nachteil des vorerwähnten Kondensators dadurch vermieden, daß gemäß der Erfindung jede Lamelle (gegebenenfalls bis auf die beiden äußeren) allseitig oxydiert ist und die beiden .äußeren Lamellen zur Kontaktgebung an der Anschlußseite blank oder über der Oxydschicht metallisiert oder durch eine entsprechende Fläche eines geeigneten Metallkörpers bzw. ihbetallblättchens überdeckt -sind.The invention now relates to an electrical capacitor composed of several layered unit lamellas made of aluminum flakes, which act as a dielectric serving aluminum oxide layer are provided. The use of mica becomes unnecessary and avoided the disadvantage of the aforementioned capacitor in that, according to the Invention, each lamella (possibly except for the two outer ones) is oxidized on all sides and the two outer lamellas for making contact on the connection side are bare or metallized over the oxide layer or by a corresponding surface of a suitable metal body or ihbetallblättchens -are covered.
Die Abbildungen veranschaulichen Ausführungsbeispiele des Kondensators nach der Erfindung.The figures illustrate exemplary embodiments of the capacitor according to the invention.
In der Abb. i ist die als Aufbauelement benutzte Einheitslamelle im Schnitt dargestellt, die aus einem an der Oberfläche allseitig oxydierten Aluminiumblättchen besteht. Hierin bedeutet i den Kern aus Aluminium und z die Oxydschicht.In Fig. I, the unit lamella used as a structural element is im Section shown, that of an aluminum sheet oxidized on all sides on the surface consists. Here i means the core made of aluminum and z the oxide layer.
Aus zwei Einheitslamellen kann man nun einen Kondensator zusammenschichten, wie dies die Abb. 2 zeigt. Die äußeren Lamellen werden an ihren Anschlußseiten mit Metallelektroden 3, die z. B. durch Metallisierungsüä chen gebildet sind, versehen.A capacitor can now be layered together from two unit lamellas, as shown in Fig. 2. The outer lamellas are on their connection sides with Metal electrodes 3, e.g. B. formed by Metallisierungsüä chen, provided.
Will man vermeiden, daß bei den sich berührenden Ein2ellamellen die Oxydflächen aufeinanderliegen und sich hierdurch schädliche Lufträume bilden, so kann man die Lamellen an einer Seite (s. Abb.3a) oder beiden Seiten (s. Abb.3b) mit Metallflächen belegen. Diese Metallflächen werden am besten im Falle der Abb. 3a aus einem weicheren, sich anschmiegenden Metall, wie z. B. Blei oder Zinn, hergestellt, während dies bei Abb.3b nicht notwendig ist. Im Falle der Abb. 3.a muß wie bei Abb. z dafür gesorgt werden, daß die fehlende eine Elektrode entsprechend aufgebracht wird. Die Metallbelege 4 können sowohl als beim Schichten dazwischengelegte Folien als auch als aufmetallisierte Flächen ausgebildet sein.If you want to avoid that the Oxide surfaces lie on top of one another and this creates harmful air spaces, see above the slats can be opened on one side (see Fig.3a) or both sides (see Fig.3b) cover with metal surfaces. These metal surfaces are best illustrated in the case of Fig. 3a made of a softer, clinging metal, such as. B. lead or tin, manufactured while this is not necessary in Fig.3b. In the case of Fig. 3.a, as in Fig. z ensure that the missing electrode is applied accordingly will. The metal covers 4 can be interposed foils during layering and also be designed as metallized surfaces.
