Description

Kondensator mit veränderbarer Kapazität. Gegenstand der Erfindung ist ein Kondensator mit veränderbarer Kapazität.Variable capacitance capacitor. Subject of the invention is a capacitor with variable capacitance.

Kondensatoren mit veränderbarer Kapazität sind in den verschiedensten Ausführungen bekannt. Die der Erfindung am nächsten kommende Ausführung ist diejenige, bei welcher auf einer Walze, welche mit einem Metallbelag versehen, ist, unter Zwischenlegung einer Isolierschicht ein zweiter Metallbelag auf- bzw. abgewickelt wird.Capacitors with variable capacitance are in the most diverse Executions known. The embodiment that comes closest to the invention is that which is on a roller, which is provided with a metal coating, with interposition an insulating layer, a second metal coating is wound up or unwound.

Bei der Erfindung kommen zwei Walzen zur Anwendung, von denen jede nur auf dem halben Umfang mit einem Metallbelag versehen .ist.The invention employs two rollers, each of which is only provided with a metal coating on half the circumference.

Der zweite Metallbelag ist ähnlich wie ein Treibriemen uni seine Riemenscheiben um beide Walzen unter Dazwischenlegen einer Isolierschicht gelegt. Diese Anordnung hat gegenüber des bisher bekannten den Vorteil, daB, keine Zahnradübeitragungen zum. Antrieb der Walzen, von welchen das Metallband oder das Isolierende Brand auf- oder abgewickelt wird, oder gegenüber .anderen bekannten Ausführungen den Vorteil, daQ; keine Federn zurr Antrieb derjenigen Walzen benötigt werden, welche das nicht auf der den Kondensator bildenden Walze liegende Band aufwickeln.The second metal coating is similar to a drive belt and its pulleys placed around both rollers with an insulating layer in between. This arrangement has the advantage over the previously known that no gear wheel contributions to the. Drive the rollers from which the metal belt or the insulating fire or is processed, or has the advantage over other known designs, daQ; no springs are needed to drive those rollers that do not Wind up the tape lying on the roller forming the capacitor.

Auf den Abbildungen ist ein Ausführungsbeispiel dargestellt.An exemplary embodiment is shown in the figures.

Abb. a zeigt den Kondensator nm AufriB. Abb. a zeigt den Kondensator im GrundriB.Fig. A shows the capacitor in elevation. Fig. A shows the capacitor in plan.

Die Walzen W1 und W2 bestehen aus Isoliermaterial und sind auf ihrem halben Umfang mit den Metallbelägen BI und Ba versehen. Um beide Walzen ist das Glimmerband G gelegt. Über dem Glimmerband G ist ein Metallband M als zweiter Kondensatorbelag angeordnet. Das Glimmerband G und das Metallband M sind durch Stifte S mit den Walzen WI und W3 verbunden. Die Walzen W1 und W' sind um ihre Achsen A und A drehbar gelagert. Die Stromzuführungen zu den einzelnen Belägen werden in der bekannten Weise durch Zuführungsspiralen oder Schleiffedern ausgeführt.The rollers W1 and W2 are made of insulating material and are provided with metal coverings BI and Ba on half their circumference. To both The mica tape G is placed on the rollers. A metal band M is located above the mica band G arranged as a second capacitor plate. The mica tape G and the metal tape M are connected to rollers WI and W3 by pins S. The rollers W1 and W 'are rotatably mounted about their axes A and A. The power supply to the individual coverings are carried out in the known manner by supply spirals or slip springs.

In der in Abb. a dargestellten Stellung hat der Kondensator seine kleinste Kapazität. Wird nun eine der beiden Walzen gedreht, so wird durch -das beide Walzen urangebende Band auch die andere Walze mitgenommen. Durch Drehung der Walzen wird sowohl der Belag BI wie der Belag Ba dem Belag 1l1 genähert, wodurch die Kapazität beständig zunimmt. Wenn die Walzen gegenüber der gezeichneten Stellung .um iSo° gedreht sind, hat der Kondensator seine größte Kapazität.In the position shown in Fig. A, the capacitor has its smallest capacity. If one of the two rollers is now rotated, then -that Both rolls of the urangent tape also took the other roll with it. By rotating the Rolling both the covering BI as the covering Ba is brought closer to the covering 1l1, as a result of which the capacity is constantly increasing. When the rollers are opposite the position shown . are rotated iSo °, the capacitor has its greatest capacity.

Selbstverständlich kann auch an Stelle des Glimmerbandes ein anderes Isoliermaterial genommen werden, z. B. Exzelsnorleinen o. dgl. Ebenso kann das Isolierband oder eine andere Isolierschicht fest um jede der Walzen gelegt werden und um beide Walzen gemeinsam nur das Metallband.Of course, a different one can also be used instead of the mica tape Insulating material can be taken, e.g. B. Exzelsnorleinen o. The like. Likewise, the insulating tape or some other layer of insulation can be tightly wrapped around each of the rollers and around both Rolls together only the metal belt.

PATENT-ANSPRUCH: Kondensator mit veränderbarer Kapazität, dadurch gekennzeichnet, daß zwei Walzen aus Isoliermaterial auf ihrem halben Umfang mit einem Metallbelag versehen sind,und daß um beideWalzen unter Dazwischenlegen einer Isolierschicht ein weiterer Metallbelag, ähnlich wie der Treibriernen um seine Riemenscheiben, gelegt ist, so daß durch Drehen der Walzen eine veränderte Kapazität erzielt wird. PATENT CLAIM: Capacitor with variable capacitance, characterized in that two rollers made of insulating material are provided with a metal coating on half their circumference, and that a further metal coating is placed around both rollers with an insulating layer in between, similar to the drive belt around its pulleys, so that a changed capacity is achieved by rotating the rollers.
