  Verfahren zur Befestigung von solationsklötzchen in Öffnungen flacher Metallkörper, beispielsweise Relaisanker oder Kontaktfedern. 



   Namentlich in elektrischen Fernsprechanlagen hat sich ergeben, dass die Befestigung kleiner Isolationsklötzchen in flachen Metallkörpern, beispielsweise in Relaisankern oder   Kontaktfedern, sieb   im Lauf des Betriebes als mangelhaft erweist. Insbesondere leidet die Befestigung dieser Isolationsklötzchen unter hohen Temperaturen, wie sie beispielsweise in Fernsprechanlagen mit selbsttätigem oder halbselbsttätigem Betrieb auftreten. Diese Temperaturen können sich da ungefähr auf 80 bis 90  C steigern. das erwärmte Isolationsmaterial verändert dabei seine Gestalt oft so weit, dass es z. B. die Kontaktfedern, auf die der Relaisanker einwirkt, ungeachtet der Ankerstellung in dauernder Berührung hält und so erhebliche Betriebsstörungen verursacht.

   Auch kann es vorkommen, dass die Isolationsklötzchen unter dem Einfluss ihrer Formänderung aus ihrer Befestigungsöffnung herausfallen. 



   Gemäss der Erfindung werden diese   Übelständc durch Anwendung eines Verfahrens   beseitigt, das auf der bekannten und verschiedentlich in der Technik verwendeten Eigenschaft des Zelluloids und ähnlicher Stoffe beruht, eine ihm durch Pressen, Ziehen oder einen ähnlichen Vorgang mitgeteilte Formveränderung zunächst beizubehalten und bei

 wird gemäss dem neuen Verfahren das Hartgummi, Zelluloid oder dgl., zweckmässig unter geeigneter Erwärmung,   durch Dfuck   verdichtet, alsdann, gegebenenfalls nach entsprechender Formgebung, in die Öffnung des Metallkörpers eingesetzt und schliesslich wieder erwärmt.

   Dadurch. dass der Druck zur Verdichtung beliebig gesteigert werden kann. wird das Wiederausdehnungsvoermögen des Isolationsklötzchens behufs Befestigung in den   Metallteilen besonders wirksam.   



   Für   viele F : i. Ue   ist es zweckmässig, das verdichtete   Material entsprechend dem   Ver-   wendungszweck durch Schneiden, Drehen   oder eine sonstige Bearbeitung so zu fotmen,

  Method for fastening insulation blocks in openings in flat metal bodies, for example relay anchors or contact springs.



   In electrical telephone systems in particular, it has been shown that the fastening of small insulation blocks in flat metal bodies, for example in relay armatures or contact springs, proves to be inadequate during operation. In particular, the attachment of these insulation blocks suffers from high temperatures, such as occur, for example, in telephone systems with automatic or semi-automatic operation. These temperatures can increase to approximately 80 to 90 C. the heated insulation material often changes its shape so far that it is z. B. the contact springs on which the relay armature acts, regardless of the armature position, keeps in constant contact and thus causes significant malfunctions.

   It can also happen that the insulation blocks fall out of their fastening opening under the influence of their change in shape.



   According to the invention, these disadvantages are eliminated by using a method which is based on the known property of celluloid and similar substances, which is used in various ways in technology, of initially maintaining and at the same time a change in shape communicated to it by pressing, pulling or a similar process
 EMI1.1
 According to the new process, the hard rubber, celluloid or the like is compressed by pressure, suitably with suitable heating, then, if necessary after appropriate shaping, inserted into the opening of the metal body and finally heated again.
 EMI1.2
 again, and thereby fastened in an extremely secure manner in the metal body.

   Thereby. that the pressure for compression can be increased as desired. the re-expansion capacity of the insulation block for fastening in the metal parts is particularly effective.



   For many F: i. It is useful to photograph the compacted material according to the intended use by cutting, turning or other processing so that

 so better adapts.
