Description

Sicherungsstreifen für Ob.erspannungssehutz durch Edelgassicherung in elektrischen Fernmeldeanlagen In elektrischen Fernmeldeanlagen ist es üblich, die Apparate häufig durch Edelgassicherungen gegenÜberspannung zu schützen. Es sind Anordnungen bekannt, welche eine Trennung der an die Sicherung angeschlossenen Leitung gestatten, ohne hierbei die Sicherung herauszunehmen; die Trennung der Leitungen erfolgt hierbei gewöhnlich durch das Einsetzen eines Prüfstöpsels o. dgl. Ein derartiger Prüfstöpsel macht.den Aufbau der Sicherungsanordnung verhältnismäßig verwickelt und teuer.Safety strip for upper voltage protection through inert gas fuse in electrical telecommunications systems In electrical telecommunications systems it is common to often to protect the apparatus against overvoltage by means of noble gas fuses. There are Arrangements known which separate the line connected to the fuse without removing the fuse; the separation of the lines usually takes place by inserting a test plug or the like The test plug makes the construction of the fuse arrangement relatively complicated and expensive.

Die Erfindung bezweckt nun, die Anwendung des Prüfstöpsels ganz zu vermeiden und dadurch den Aufbau der Sicherungsanordnun- erheblich zu vereinfachen. Sie erreicht dies dadurch, daß ein Verbindungsglied zwischen der Leitung und der Sicherung unter einer Federspannung steht, welche beim Lösen eines Spertgliedes zur Wirkung kommt und die Verbindung selbsttätig unterbricht.The invention now aims to fully apply the test plug avoid and thereby considerably simplify the construction of the fuse arrangement. You achieve this by having a connecting link between the line and the Fuse is under a spring tension, which when loosening a locking member comes into effect and automatically interrupts the connection.

Die Abbildung zeigt eine Ausführungsform der neuen Anordnung.The figure shows an embodiment of the new arrangement.

DasVerbindungsglied i zeichnet sich durch besonders einfachen Aufbau aus; denn es ist derart ausgebildet, daß es zusammen mit der AnschlußÖse 4 für die Leitung 3 aus einem Stück federnden Materials besteht. Ist die Leitung durchgeschaltet, so wird das Verbindungsglied i mittels einer Schraube 5 gegen dieUnterlage 8 gepreßt. Will man zur Prüfung die Leitung unterbrechen, so genügt ein einfaches Lösen dieser Schraube, um das Verbindtingsglied i nach oben durchfedern zu lassen. Ein Schluß des federnden Verbindungsgliedes i mit dem Sicherungsträger 7 wird durch ein an diesem angeordnetes Isolierstück 6 verhindert.The connecting member i is characterized by a particularly simple structure; because it is designed in such a way that, together with the connecting eyelet 4 for the line 3, it consists of a piece of resilient material. If the line is switched through, the connecting member i is pressed against the base 8 by means of a screw 5. If you want to interrupt the line for testing, a simple loosening of this screw is sufficient to let the connecting member i spring upward. A closure of the resilient connecting member i with the fuse carrier 7 is prevented by an insulating piece 6 arranged on the latter.
