Description

DEUTSCHESGERMAN

Es ist bekannt, Kontaktfedern entsprechend der jeweils gewünschten Vorspannung nachzuregulieren. Bei Federn, die zusammen mit einer Federstütze in einem Isolierkörper eingespannt sind, muß man z. B. beim Verstellen der Federstütze meist auch die Kontaktfedern nachregulieren. Bei anderen Kontaktfedern, die mit der Federstütze außerhalb deren Einspannung verbunden sind, bleibt die von vornherein eingestellte Federvorspannung erhalten, auch wenn die Stellung der Stütze noch ausgerichtet wird.It is known to readjust contact springs according to the preload desired in each case. For springs that are clamped together with a spring support in an insulating body, you have to z. B. When adjusting the spring support, usually readjust the contact springs as well. With other contact springs, that are connected to the spring support outside of its restraint remains the one set from the start Preserve the spring preload even if the position of the support is still being aligned.

Besonders bei Kontaktfedern empfindlicher Relais mit hohem Gütefaktor ist es nun erwünscht, außer der Federvorspannung auch die zweckmäßigste Federsteilheit einstellen zu können, um die Lastkurve der Kraftkurve möglichst gut anzupassen. Eine ähnliche Aufgabe liegt z. B. bei Resonanzrelais vor, deren federnde Ankerzungen mechanisch auf die Frequenz bestimmter Signalströme eingestellt werden sollen. Die für diese Einstellung bekannten Vorrichtungen, bei denen zwei kurvenförmig gebogene Flachfedern zusammen mit der Ankerzunge eingespannt sind und durch eine Schraube mehr oder weniger weit gegen die Zunge gepreßt werden, ermöglichen jedoch nur eine Feineinstellung in einem sehr begrenzten Bereich. Diese Vorrichtungen sind aber auch nur für Relais mit nebeneinanderliegenden Ankerzungen bzw. Kontaktfedern, nicht aber für Relais mit dicht übereinanderliegenden Kontakten anwendbar. Die bei Kontaktfedern häufig erwünschte Änderung der Federcharakteristik über einen größeren Bereich wäre nur durch Lösen der gesamten Einspannung und Längsverschiebung der Federn möglich. Dabei würde sich aber der Kontaktpunkt verlagern, so daß entweder an der Feder oder an den Gegenkontakten entsprechend große Kontaktniete vorhanden sein müßten.It is now particularly desirable for contact springs of sensitive relays with a high quality factor, except the spring preload to adjust the most appropriate spring steepness to the load curve of the Adapt the force curve as well as possible. A similar task is z. B. before resonance relays whose resilient armature tongues should be mechanically adjusted to the frequency of certain signal currents. The devices known for this setting, in which two curved flat springs are clamped together with the anchor tongue and more or less far against by a screw the tongue are pressed, however, only allow fine adjustment in a very limited range. These devices are only for relays with adjacent armature tongues or contact springs, but not applicable to relays with closely stacked contacts. The one with contact springs Frequently desired change in the spring characteristics over a larger area would only be possible by loosening the entire clamping and longitudinal displacement of the springs. Doing so would but shift the contact point so that either on the spring or on the mating contacts accordingly large contact rivets should be available.

Gemäß der Erfindung wird bei Kontaktfedern die Anordnung so getroffen, daß die Kontaktfedern und die Federstützen durch Klemmstücke verbunden sind, durch deren Verstellen in Längsrichtung der Federn bei unveränderter Gesamtlänge der Kontaktfedern und Federstützen der die federnde Länge und die Charakteristik der Kontaktfedern bestimmende Auflagepunkt verändert werden kann.According to the invention, the arrangement is made so that the contact springs and contact springs the spring supports are connected by clamping pieces by adjusting them in the longitudinal direction of the springs with the total length of the contact springs and spring supports unchanged, the resilient length and the Characteristic of the contact springs determining support point can be changed.

Das Klemmstück 3 wird zweckmäßigerweise U-förmig ausgebildet, damit es die Feder 1 und die Stütze 2 umfaßt und trotz der Einlochbefestigung die Lage dieser Teile zueinander sicherstellt.is changed by the resilient length of the spring 1. The clamping piece 3 is expediently U-shaped designed so that it includes the spring 1 and the support 2 and despite the one-hole fastening the position of these parts to each other.

Fig. 3 zeigt eine andere Ausführung, bei welcher das Klemmstück 3 als verformbarer Bügel 3 ausgebildet ist. Das eine Ende des Bügels ist mit der Feder und der Federstütze fest verbunden. Das andere freie Ende 3" des U-förmig gebogenen Bügels stützt die Kontaktfeder lediglich ab. Ohne Lösen der Verbindung nur durch Verbiegen des Bügels 3 kann der Auflagepunkt des freien Endes 3a der Feder 1 verändert werden.3 shows another embodiment in which the clamping piece 3 is designed as a deformable bracket 3. One end of the bracket is firmly connected to the spring and the spring support. The other free end 3 'of the U-shaped bracket supports the contact spring only from. Without releasing the connection only by bending of the bracket 3, the supporting point of the free end 3 can be a spring 1 changes.
