Description

Aus der deutschen Offenlegungsschrift 24 32 454 ist z. B. eine Schaltung bekanntgeworden, mit der es möglich ist, ein sogenanntes »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 einFrom the German Offenlegungsschrift 24 32 454 z. B. became known a circuit with which it it is possible to create a so-called »flash criterion«, d. H. a defined short-term interruption to the Purposes of further dialing in telephone exchange systems. In this circuit, it becomes the short-term interruption effect generating switching path bridged by a key contact, so that only when you let go the actual interruption process begins. The disadvantage with this circuit is in it too see that when the button is pressed, only one

Obergang von der durchschaltenden Halbleiterstrecke zur kurzschließenden Tastenkontaktstrecke erfolgt.The transition from the through-switching semiconductor path to the short-circuiting key contact path takes place.

Eine andere DE-OS 24 32 452 bezieht sich auf eine Schaltung, bei der der Flash-Taste je nach Stellung des Gabelumschalters zwei Funktionen zugeordnet sind, wobei die eine Funktion mechanisch und die andere elektrisch ausgeführt wird. Im Gegensatz zu der erfindungsgemäßen Schaltungsanordnung wird bei dieser Schaltung die Unterbrechungszeit durch die Dauer des Tastendruckes definiertAnother DE-OS 24 32 452 relates to a circuit in which the flash button depending on the position of the Hook switch are assigned two functions, one function being mechanical and the other is carried out electrically. In contrast to the circuit arrangement according to the invention, at In this circuit, the interruption time is defined by the length of time the button is pressed

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

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Unterbrechungsvorgang bei Betätigen der Taste von einem Relais mit zwei Wicklungen eingeleitet wird, dessen eine Wicklung das Relais durch die Entladung eines ersten Kondensators bei Betätigen der Taste zum Anzug bringt und dessen andere Wicklung durch die Entladung eines zweiten Kondensators über eine durchgeschaltete Triggerdiode durch Gegenerregung das Relais zum Abfall bringt.
Ein Ausführungsbeispiel der erfindungsgemäßen Schaltungsanordnung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben:This object is achieved according to the invention in that the interruption process is initiated when the button is pressed by a relay with two windings, one winding of which causes the relay to pick up by discharging a first capacitor when the button is pressed and the other winding of which by discharging a second Capacitor brings the relay to drop by counter-excitation via a connected trigger diode.
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 Ci die Wicklung Fi aktiviert, wodurch der Reiaiskontakt f geöffnet wird. NachWhen the button T is pressed, the winding Fi is activated by the capacitor Ci charged via R] , whereby the relay contact f is opened. To

öffnung des Kontaktes f lädt sich C2 über R2 bis zur Erreichung der Zündspannung der Triggerdiode A auf und entlädt sich dann über F2. Diese Zeit bis zum Erreichen der Zündspannung der Triggerdiode A ist identisch mit der Unterbrechungszeit Somit ist die Unterbrechungszeit von der Größe des Widerstandes /?2 und des Kondensators C2 direkt abhängig. Über die niederohmige Schaltstrecke R3, At gibt der Kondensator nach Ende der Unterbrechung seine Restladung ab.
Der mit der erfindungsgemäßen Schaltung erzielte Vorteil becteht insbesondere darin, daß während des Unterbrechungsvorganges weitere Tastenbetätigungen keinen Einfluß auf den Schaltvorgang haben.When contact f opens, C 2 is charged via R 2 until the ignition voltage of trigger diode A is reached and then discharges via F2. This time until the trigger diode A reaches the ignition voltage is identical to the interruption time. The interruption time is therefore directly dependent on the size of the resistor /? 2 and the capacitor C2. After the end of the interruption, the capacitor releases its residual charge via the low-resistance switching path R3, At.
The advantage achieved with the circuit according to the invention is in particular that further key actuations have no influence on the switching process during the interruption process.
