Schaltungsanordnung zur kurzzeitigen Unterbrechung von Fernsprechverbindungen.Circuit arrangement for the brief interruption of telephone connections.

Die Erfindung betrifft eine Schaltungsanordnung zur kurzzeitigen Unterbrechung von Fernsprechverbindungen.The invention relates to a circuit arrangement for briefly interrupting telephone connections.

Aus der deutschen Offenlegungsschrift Nr. 24 32 454 ist z.B. eine Schaltung bekanntgeworden, mit der es möglich ist, ein sogen· "Flash-Kriterium" herzustellen, d.h. eine definierte Kurzzeitunterbrechung zum Zwecke der Weiterwahl in Fernsprechnebenstellenanlagen. In dieser Schaltung wird die den Kurzzeitunterbrechungseffekt erzeugende Schaltstrecke durch einen Tastenkontakt überbrückt, so daß erst beim Loslassen der Taste der eigentliche Unterbrechungsvorgang beginnt. Der Nachteil bei dieser Schaltung ist darin zu sehen, daß bei Betätigung der Taste lediglich ein Übergang von der durchschaltenden Halbleiterstrecke zur kurzschließenden Tastenkontaktstrecke erfolgt.From the German Offenlegungsschrift No. 24 32 454 is for example a circuit has become known with which it is possible to produce a so-called "flash criterion", i.e. a Defined short-term interruption for the purpose of further dialing in telephone exchange systems. In this circuit will the switching path generating the short-term interruption effect is bridged by a key contact, so that only the actual interruption process begins when the button is released. The disadvantage of this circuit is that when the button is pressed, only one Transition from the through-switching semiconductor path to the short-circuiting key contact path takes place.

Der Erfindung liegt daher die Aufgabe zugrunde, unter Vermeidung der vorgenannten Nachteile, eine Schaltung zu konzipieren, die bereits mit Beginn des Tastendrucks den Unterbrechungsvorgang einleitet.The invention is therefore based on the object, while avoiding the aforementioned disadvantages, to design a circuit which initiates the interruption process as soon as the key is pressed.

Diese Aufgabe wird erf indungsgema'ß dadurch gelöst, daß der Unterbrechungsvorgang nach Auslösung durch eine Taste von einem Relais mit zwei Wicklungen erfolgt, wobei die eine !Wicklung durch die Entladung eines ersten Kondensators über die Taste und die andere Wicklung durch die Entladung eines zweiten Kondensators über eine durchschaltende Triggerdiode aktiviert wird.This object is achieved according to the invention in that the Interrupting process takes place after triggering by a button of a relay with two windings, one of which ! Winding by discharging a first capacitor via the button and the other winding by discharging a second capacitor is activated via a through-switching trigger diode.

Ein Ausführungsbeispiel der erfindungsgemäßen Schaltungsanordnung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben:An embodiment of the circuit arrangement according to the invention is shown in the drawing and is described in more detail below:

Bei Betätigung der Taste T wird durch den über R.. geladenen Kondensator C. die Wicklung F. aktiviert, wodurch der Relaiskontakt f geöffnet wird. Nach öffnung des Kontaktes f lädt sich C2 über Rp bis zur Erreichung der Zündspannung der Triggerdiode D. auf und entlädt sich dann über F-. Diese^ Zeit bis zum Erreichen der Zündspannung der Triggerdiode D-. ist identisch mit der Unterbrechungszeit. Somit ist die Unterbrechungszeit von der Größe des Widerstandes R~ und des Kondensators C~ direkt abhängig. Über die niederohmige Schaltstrecke R3, D3 gibt der Kondensator nach Ende der Unterbrechung seine Restladung ab οWhen the T button is pressed, the capacitor C. charged via R .. activates the winding F., which opens the relay contact f. After the contact f has opened, C 2 is charged via Rp until the ignition voltage of the trigger diode D is reached and then discharges via F-. This ^ time until the ignition voltage of the trigger diode D - is reached . is identical to the interruption time. The interruption time is thus directly dependent on the size of the resistor R ~ and the capacitor C ~. After the end of the interruption, the capacitor releases its residual charge via the low-resistance switching path R 3 , D 3 ο

Der mit der erfindungsgemäßen Schaltung erzielte Vorteil besteht insbesondere darin, daß während des Unterbrechungsvorganges weitere Tastenbetätigungen keinen Einfluß auf den Schaltvorgang haben.The advantage achieved with the circuit according to the invention exists in particular that during the interruption process further key actuations have no effect on the Have switching operation.
