Description

Kondensator. Außer den sogenannten Drehkondensatoren sind bereits Kondensatoren mit veränderlicher Kapazität bekanntgeworden, bei welchen auf eine Walze aus Isoliermaterial Metallbänder unter Zwischenfügung von Isolierbändern auf-und abgewickelt werden. Gegenüber diesen bekannten Einrichtungen betrifft die Erfindung einen einfacheren und billiger herzustellenden Kondensator, der sich dadurch kennzeichnet, daß die `Valze, auf welche das Metallband auf-und abgewickelt wird, aus Metall besteht, und die eine Belegung des Kondensators bildet, wobei auf der Walze ringförmige Erhöhungen aus Isoliermaterial vorgesehen sind, gegen welche sich das die andere Belegung bildende auf- und abwickelbare Metallband anlegt.Capacitor. Besides the so-called rotary capacitors are already Capacitors with variable capacitance become known, in which on a Roller made of insulating material Metal strips with the interposition of insulating strips on and off be handled. The invention relates to these known devices a simpler and cheaper to manufacture capacitor, which is characterized by that the roller on which the metal tape is wound and unwound is made of metal, and which forms an occupancy of the capacitor, with annular bumps on the roller made of insulating material are provided against which the other occupancy is formed Metal tape that can be wound and unwound is applied.

Auf der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes dargestellt.The drawing shows an embodiment of the subject matter of the invention shown.

Auf der mit einem Knopf zum leichten Drehen versehenen Metallwalze a, deren Oberfläche die eine Belegung des Kondensators bildet, sind kleine ringförmige Vorsprünge h aus Isoliermaterial vorgesehen, gegen welche sich das die zweite Belegung darstellende Metallband c beim Aufwickeln anlegt. Der zwischen Metallband und Oberfläche der Walze a verbleibende Luftraum d bildet hierbei die Isolierung. Das Metallband ist zweckmäßig an einer in einem Gehäuse liegenden Spiralfeder angeschlossen, doch kann es auch durch federnd angedrückte Spannwalzen gehalten werden. Letztere Ausführungsform . hat gegenüber der Rückzugsfed6r den Vorteil, daß sie praktisch den gleichen Hemmungswiderstand für beide Drehrichtungen der Hauptwalze ausübt und dabei ein glattes Auf-und Abwickeln des Metallbandes gewährleistet. In diesem Falle muß selbstverständlich zwischen Haupt- und Vorratswalze eine mechanische Kupplung, beispielsweise ei11 Zahnradgetriebe o. dgl., vorgesehen werden.On the metal roller with a knob for easy turning a, the surface of which forms an occupancy of the capacitor, are small ring-shaped Projections h made of insulating material are provided, against which the second occupancy performing metal tape c applies when winding. The one between the metal band and the surface the remaining air space d of the roller a forms the insulation. The metal band is expediently connected to a spiral spring lying in a housing, but it can also be held by spring-loaded tension rollers. The latter embodiment . has the advantage over the retraction spring that it has practically the same inhibition resistance exerts for both directions of rotation of the main roller and thereby a smooth winding and unwinding of the metal band guaranteed. In this case, of course, between Main roller and supply roller have a mechanical coupling, e.g. ei11 gear transmission o. The like., Are provided.
