  Schutzrohrbefestigung für Leuchten mit röhrenförmigen Lampen

 hindern. Um ein Lösen der Überwurfmutter 8 durch Unbefugte auszuschliessen, ist vorzugsweise eine Fixierung derselben vorgesehen, beispielsweise durch Anordnung eines Gewindes 20 im Fassungskörper 3, das eine Schraube 21 aufnimmt, die erst nach Lösen des Verschlussdeckels 10 lösbar ist. 



   Die Vorteile der   erfindungsgemässen   Ausführung bestehen in der zuverlässigen Festlegung des Schutzrohres sowie in der einfachen Montage desselben, wobei Beschädigungen der Lampe ausgeschlossen sind. 



  Das Einführen des Schutzrohres in die Fassungskörper wird dadurch wesentlich erleichtert, dass das Schutzrohr durch jeden der beiden Fassungskörper hindurchgeschoben werden kann. 



    PATENTANSPRÜCHE :    
1. Schutzrohrbefestigung für vorzugsweise explosionsgeschützte Leuchten mit röhrenförmigen Lampen, insbesondere Leuchtstoffröhren, deren Fassungen aus einem einen Kontakteinsatz aufnehmenden Fassungkörper, in den das Schutzrohr erstreckt ist, und einem Verschlussdeckel bestehen und mit einer Überwurfmutter und einem Dichtungsring für das Schutzrohr versehen sind, dadurch gekennzeichnet, dass in den   Fassungskörper (3 , dessen kleinster innerer   Durchmesser vorzugsweise grösser als der Aussendurchmesser des Schutzrohres (6) ist, eine Fixierscheibe (13) zur Begrenzung der Längsverschiebbarkeit des Schutzrohres (6) eingelegt ist.

 prevent. In order to rule out loosening of the union nut 8 by unauthorized persons, the same is preferably fixed, for example by arranging a thread 20 in the socket body 3, which receives a screw 21 that can only be released after the closure cover 10 has been loosened.



   The advantages of the design according to the invention consist in the reliable fixing of the protective tube and in the simple assembly of the same, with damage to the lamp being excluded.



  The introduction of the protective tube into the socket body is made considerably easier because the protective tube can be pushed through each of the two socket bodies.



    PATENT CLAIMS:
1. Protection tube fastening for preferably explosion-proof lights with tubular lamps, in particular fluorescent tubes, the sockets of which consist of a socket body which accommodates a contact insert and into which the protection tube extends, and a closure cover and is provided with a union nut and a sealing ring for the protection tube, characterized in that, that in the socket body (3, whose smallest inner diameter is preferably larger than the outer diameter of the protective tube (6), a fixing disk (13) is inserted to limit the longitudinal displacement of the protective tube (6).

 

Claims (1)

2. Schutzrohrbefestigung nach Anspruch l, dadurch gekennzeichnet, dass der Kontaktteil (5) an der Fixierscheibe (13) befestigt ist. 2. Protection tube fastening according to claim l, characterized in that the contact part (5) is fastened to the fixing disc (13). 3. Schutzrohrbefestigung nach Anspruch 1 oder 2, dadurch gekennzeichnet, dass die Fixierscheibe (13) mit zwei dem Schutzrohr axial anliegenden Ansätzen (14,15) ungleicher Stärke versehen ist. 3.
