Description

Die Erfindung bezieht sich auf einen Wellenbereichumschalter mit Spulenrevolv er und einem Kondensator für Ultrakurzwellengeräte. Damit ein guter Kontakt zwischen den einzelnen Spulen und dem Kondensator gewährleistet ist, werden beim Weiterschalten des Spulenrevolvers mittels der längs verschiebbaren Revolverwelle zunächst die Kontakte voneinander abgehoben und dann nach der Schalterdrehung für den neueingestellten Bereich wieder geschlossen. Dies allein genügt aber nicht für die gute Wirkung des Wellenbereichumschalters; denn beim Betrieb mit Ultrakurzwellen ist es nötig, recht kurze Verbindungsleitungen zwischen Spulen und Kondensator zu haben. Diese Forderung wird gemäß der Erfindung dadurch erfüllt, daß unmittelbar an der Peripherie des Spulenrev olvers der Kondensator angeordnet ist und daß die am Umfang des Spulenrev olvers hervorstehenden Kontakte mit kurzen Kontaktfedern am Kondensator zusammenarbeiten.The invention relates to a waveband switch with a reel turret he and a capacitor for ultra-short wave devices. So that a good contact between the individual coils and the capacitor are guaranteed when switching of the bobbin turret by means of the longitudinally displaceable turret shaft first the Contacts lifted from each other and then after turning the switch for the newly set Area closed again. But this alone is not enough for the good effect of the Waveband switch; because when operating with ultra-short waves it is necessary, right to have short connecting lines between the coils and the capacitor. This requirement is fulfilled according to the invention in that immediately on the periphery of the Spulenrev olvers the capacitor is arranged and that the circumference of the Spulenrev olver's protruding contacts work together with short contact springs on the capacitor.

In der Zeichnung ist eine beispielsweise Ausführungsform der Erfindung zur Darstellung gebracht. Abb. i zeigt den ganzen Umschalter und Abb. z den Spulenrevolver für sich.In the drawing is an exemplary embodiment of the invention brought to the display. Fig. I shows the entire switch and Fig. Z shows the bobbin turret for themselves.

Auf einer Grundplatte a sind die Welle b eines Spulenrevolvers c sowie die Welle d eines Kondensators e gelagert. Am Umfang des Spulenrevolvers sind Kontakte g für jede Spule vorgesehen, während am Kondensator die mit den Kontakten g zusammenarbeitenden Kontaktfedern lt so angebracht sind, daß sie so kurz wie möglich sind. Auf diese Weise wird eine längere, unbestimmte Verbindung der Spulen vermieden. Dabei sind die Federn immerhin so lang auszuführen, daß sie ihre Federung nicht einbüßen. The shaft b of a reel turret c and the shaft d of a capacitor e are mounted on a base plate a. Contacts g for each coil are provided on the circumference of the reel turret, while the contact springs lt cooperating with the contacts g are attached to the capacitor in such a way that they are as short as possible. In this way, a longer, indefinite connection of the coils is avoided. The springs are to be designed so long that they do not lose their springiness.
