Description

Auf Kabeldosen, Zwillingsverschraubungen usw. wurde bisher der Deckel durch Schraubgewinde, Schrauben oder Muttern befestigt. Gegenstand der @-orllegenden Erfindung ist eine Deckelbefestigungsart, bei der keine zusätzlichen Befestigungsmittel benötigt werden. An der Innenwand des Dosenhohlraums werden durch besondere Gestaltung des Preßwerkzeugs zwei Nocken i mit angepreßt, deren untere Fläche 2 keilförmig ansteigt. Am Deckelteil stehen zwei Isolierstoffkrallen 3 vor, deren obere Fläche 4 unter demselben Winkel keilförmig verlaufen wie die Nocken des Dosenteils. Bei einer Rechtsdrehung des Deckels gleiten die keilförmigen Flächen 2 und 4 aufeinander und pressen den Deckel gegen den hochstehenden Rand des Dosenteils. Ein im Deckel eingelegter Gummiring 5 dichtet dabei Dose und Deckel wasserdicht gegeneinander ab. Der Deckel kann nachträglich noch durch eine Arretierschraube bekannter Art gesichert werden, so daß sie nur mittels Werkzeug zu lösen ist.So far, the cover was on cable sockets, twin screw connections, etc. fastened by screw threads, screws or nuts. Subject of the @ -orllegends Invention is a type of lid fastening in which no additional fastening means are needed. On the inside wall of the can cavity are through a special design of the pressing tool with two cams i pressed, the lower surface 2 of which is wedge-shaped increases. On the cover part there are two insulating material claws 3, the upper surface of which 4 run wedge-shaped at the same angle as the cams of the can part. at a clockwise rotation of the cover, the wedge-shaped surfaces 2 and 4 slide on one another and press the lid against the raised edge of the can part. One in the lid inserted rubber ring 5 seals the can and lid against each other in a watertight manner away. The cover can subsequently be secured with a locking screw of a known type be secured so that it can only be solved with a tool.

Die Zeichnung zeigt ein Ausführungsbeispiel. Abb. i zeigt die geöffnete Dose mit den beiden angepreßten Nocken i und deren keilförmige untere Fläche 2; Abb.2 zeigt den Deckel mit den Befestigungskrallen 3 und deren keilförmige Fläche 4. Im Deckel ist der Weichgummiring 5 eingelegt.The drawing shows an embodiment. Fig. I shows the opened Can with the two cams i pressed on and their wedge-shaped lower surface 2; Fig.2 shows the cover with the fastening claws 3 and their wedge-shaped surface 4. The soft rubber ring 5 is inserted in the cover.
