Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Bei den modernen Fernsprechämtern werden für die verschiedenen Stromkreise oft Signallampen von verschiedenen Spannungen oder Stromstärken erforderlich. Bisher ist jedoch keine Fassung oder Stromzuführung für diese Lampen bekannt geworden, bei der ohne größere Schwierigkeiten eine Unverwechselbarkeit der Lampen erreicht worden wäre. Der vorliegenden Erfindung gemäß wird nunIn modern telephone exchanges, signal lamps are often used for the various circuits of different voltages or currents required. So far, however, there is no socket or power supply for this Lamps have become known in which a distinctiveness without major difficulties the lamps would have been reached. According to the present invention will now

ίο diese Aufgabe in einfacher und sicherer Weise dadurch gelöst, daß die Stromzuführung zu der Lampe über Ringe erfolgt, welche um die röhrenförmige Glashülle derselben herumgelegt sind, und zwar derart, daß sich die Ringe für Lampen gleicher Spannung auch in gleicher Höhenlage befinden. Die dementsprechend verschieden lang ausgebildeten Kontaktfedern führen also nur einer ganz bestimmten Lampenart Strom zu; etwa irrtümlich eingesteckte Lampen anderer Spannung oder Stromstärke bleiben stromlos.ίο this task in an easier and safer way Way solved in that the power supply to the lamp takes place via rings, which around the tubular glass envelope of the same are laid around in such a way that the rings for lamps of the same voltage are also at the same height. The contact springs, which are accordingly designed to be of different lengths, only carry current for a very specific type of lamp to; For example, incorrectly plugged in lamps with a different voltage or current intensity remain currentless.

Auf der beiliegenden Zeichnung ist eine Ausführungsform der Erfindung dargestellt.An embodiment of the invention is shown in the accompanying drawing.

Bei den drei Lampen 1, 2, 3 sind die Ringe c und d in verschiedener Höhe um die Glashülle gelegt, und dementsprechend ist die Länge der Federn α und b gewählt, so daß für eine bestimmte Fassung nur Lampen entsprechender Spannung benutzt werden können.In the three lamps 1, 2, 3, the rings c and d are placed at different heights around the glass envelope, and the length of the springs α and b is selected accordingly, so that only lamps of the corresponding voltage can be used for a certain socket.

Zweckmäßig wird man die Kontaktstellen derart anordnen, daß die Spannung nach dem Lampenfuße hin zunimmt, damit man beim versehentlichen Einsetzen von Lampen zu niedriger Spannung nicht an den Kontaktfedern für höhere Spannung vorüberkommt.Appropriately, you will arrange the contact points in such a way that the voltage after increases towards the base of the lamp, so that if the lamp is accidentally inserted, the voltage is too low on the contact springs for higher tension comes over.

Selbstverständlich steht der Verwendung des Erfindungsgegenstandes auch für andere als Fernsprechzwecke nichts im Wege.Of course, the subject matter of the invention can also be used for others nothing in the way of telephone purposes.
