Description

In vielen Zweigen der elektrischen Fernmeldetechnik werden Drehschauzeichen verwendet. Die Drehschauzeichen bekannter Art sind mit Spiralfedern ausgerüstet, um nach Abschaltung der Erregungsspannung das Drehorgan in die Ruhestellung zurückzuführen. Solche Spiralfedern werden bisher entweder nach Art der Unruhfedern oder über einen zylindrischen Dorn gewickelt, ausgeführt.Rotary indicators are used in many branches of electrical telecommunications technology used. The rotary indicators of a known type are equipped with spiral springs, in order to return the rotary element to the rest position after the excitation voltage has been switched off. Such coil springs are so far either on the type of balance springs or a cylindrical mandrel wound, executed.

Infolge der kleinen Abmessungen, welche im allgemeinen bei den Drehschauzeichen üblich sind, besitzen die Elektromagnetsysteme nur ein, ganz geringes Drehmoment, demzufolge auch die Rückzugskraft der Federn nur klein sein darf. Diese Bedingung führt zu Spiralfedern, die schwer in gleichmäßiger Güte zu fertigen sind. Ein weiterer Nachteil besteht darin, daß nach Einsbau und, Justierung solche empfindlichen Federn durch Stöße, Erschütterungen oder sonstige äußere Einwirkungen, insbesondere beim Transport, so verändert oder einzelne Windungen derselben so verlagert werden können, daß eine unzulässige Änderung der vorgegebenen elektrischen Bedingungen eintritt.As a result of the small dimensions, which are generally the case with rotary indicators are common, the electromagnetic systems only have a very low torque, consequently the retraction force of the springs may only be small. This condition leads to coil springs that are difficult to manufacture in a uniform quality. Another The disadvantage is that after installation and adjustment, such sensitive springs by shocks, vibrations or other external influences, especially when Transport, so changed or individual turns of the same can be relocated, that an impermissible change in the specified electrical conditions occurs.

Mit der vorliegenden Erfindung werden die gesamten Nachteile beseitigt. Die Stal),feder a ist in einfachster Weise aus gestrecktem Material herzustellen und Stöße oder Erschütterungen können keine Veränderung der Rückzugskraft bewirken. Damit die Rückzugskraft sowohl in Ruhestellung als auch in Arbeitsstellung b des Drehorgans d möglichst wenig Unterschied aufweist, so daß die Justierung erleichtert wird, soll erfindungsgemäß das Arbeitsende c der Stabfeder a nahe dem Drehpunkt f des Drehorgans d angeordnet werden.The present invention overcomes all of the disadvantages. The Stal), spring a can be produced in the simplest way from stretched material and shocks or vibrations cannot cause any change in the retraction force. So that the retraction force has as little difference as possible both in the rest position and in the working position b of the rotating member d, so that the adjustment is facilitated, according to the invention the working end c of the rod spring a should be arranged near the pivot point f of the rotating member d .
