    Wasserdichter Anschluss- und Sicherungskasten für Fernsprechanlagen   mit
Hochspannungsschutz. 



   Für den telephonischen Verkehr über parallel zu   Starkstrom-Hochspannungs-   freileitungen verlegte Fernsprechleitungen dienten bisher transportable oder in bestimmten Abständen längs der Strecke stationär eingebaute Fernsprechstationen, welche mit den erforderlichen Hochspannungseinrichtungen versehen waren. Die transportablen Fernsprechstationen sind wegen der notwendigen Sicherheitseinrichtungen für den Transport wenig geeignet ; ausserdem ist das Anschalten (mittels Schaltstange) und deren sonstige Bedienung nicht ungefährlich. Die stationären Fernsprechstationen haben dagegen den Nachteil, dass die verhältnismässig empfindlichen Fernsprechapparate dauernd den Witterungseinflüssen im Freien ausgesetzt sind, gegen welche sie auch durch Einbau in wasserdichte Gehäuse oder dgl. nicht vollkommen geschützt werden können. 



   Gemäss der Erfindung werden diese Nachteile dadurch vermieden, dass an Stelle der stationäreu Fernsprechstationen mit vollständigem Hochspannungsschutz wasserdichte Anschluss-und Sicherungskästen angeordnet sind, welche alle zur Sicherung eines ge-   wöhnlichen   Fernsprechapparates erforderlichen bekannten Einrichtungen, wie Blitzableiter, Sicherungen, Isoliertransformator usw. enthalten und das rasche, gefahrlose Anschalten eines gewöhnlichen, transportablen Fernsprechapparates gestatten, ohne dass der Anschlusskasten geöffnet werden muss. 



   Auf der Zeichnung ist eine Ausführungsform des neuen   Anschluss-und Sicherungs-   kastens dargestellt. Er besteht aus einem geerdeten Metallgehäuse a, das durch eine Türe wasserdicht verschlossen werden kann. Das Gehäuse enthält die zur Sicherung eines
Fernsprechapparates erforderlichen Einrichtungen, beispielsweise einen Blitzableiter b,
Sicherungen c, sowie einen Isoliertransformator d. An der Unterseite des Gehäuses ist ein
Steckkontakt e angeordnet, an welchen man einen transportablen Fernsprechapparat ohne Öffnung der Tür anschliessen kann. 



   Das geerdete Metallgehäuse schützt die Bedienungeperson vollkommen auch bei
Isolationsfehlern der stromführenden Teile im Innern des Kastens.

    Waterproof connection and fuse box for telephone systems with
High voltage protection.



   For telephone traffic over telephone lines laid parallel to high-voltage overhead lines, portable telephone stations or telephone stations installed at certain intervals along the route, which were provided with the necessary high-voltage equipment, were previously used. The portable telephone stations are not very suitable for transport because of the necessary safety devices; In addition, switching on (using the switch rod) and other operations is not without risk. The stationary telephone stations, on the other hand, have the disadvantage that the relatively sensitive telephone sets are constantly exposed to the effects of the weather in the open air, against which they cannot be completely protected, even by installing them in waterproof housings or the like.



   According to the invention, these disadvantages are avoided in that, instead of the stationary telephone stations with full high-voltage protection, watertight connection and fuse boxes are arranged which contain all the known devices required to secure a conventional telephone set, such as lightning rods, fuses, isolating transformers, etc. allow quick, safe connection of an ordinary, portable telephone set without having to open the junction box.



   The drawing shows an embodiment of the new connection and fuse box. It consists of a grounded metal housing a, which can be closed watertight by a door. The housing contains the securing one
Telephone equipment required, for example a lightning rod b,
Fuses c and an isolating transformer d. At the bottom of the case is a
Plug contact e arranged to which you can connect a portable telephone without opening the door.



   The earthed metal housing completely protects the operator even when
Insulation faults in the live parts inside the box.
