Description

Bei Klemmen, insbesondere bei Reihenklemmen, die, in großer Zahl nebeneinander angeordnet, in Schaltanlagen verwendet werden, ist es mitunter notwendig, eine Sicherung für die Klemmschraube vorzusehen, um ein unbeabsichtigtes Lockern der Anschlüsse zu verhindern. Dies gilt insbesondere dann, wenn für die Anschlußleitungen ein Werkstoff benutzt wird"d@er, wiebeispielaweiseAluminium, zum Fließen neigt, der also unter -dem Druck ,der Klemmschraube sich verformt und damit nicht mehr von der Klemmschraube festgehalten wird.In the case of terminals, especially in the case of terminal blocks, which are next to each other in large numbers arranged to be used in switchgear, it is sometimes necessary to have a fuse for the clamping screw to prevent unintentional loosening of the connections to prevent. This is especially true when a material is used for the connecting lines is used "d @ er, such as aluminum, tends to flow, that is, under -the pressure, the clamping screw is deformed and thus no longer from the clamping screw is being held.

Für die Sicherung der Klemmschrauben bzw. für -die Sicherstellung eines stets einwandfreienAnpressungsdruckes, auch bei Verwendung von Aluminium und ähnlichen Werkstoffen, sind schon viele Vorschläge gemacht worden. Diese Vorschläge gehen fast alle darauf hinaus, daß man einen federnden Teil, insbesondere einen Federring, entweder zwischen den Klemmkörper und die Klemmschraube oder zwischen nie Klemmschraube und: die Anschlußdrähte eingeschaltet hat. Derartige Konstruktionen sind jedoch nicht nur kostspielig, sondern vielfach in der Bedienung kompliziert, sofern man nicht noch besondereSicherungsmaßnahmen vorsieht, um ein Herausfallen der Federn zu verhindern. Alle ,diese Nachteile werden gemäß der Erfindung :dadurch vermieden, daß man den aus einem einzigen Teil bestehenden Klemmkörper in sich elastisch dadurch gestaltet, daß man die der Klemmschraube gegenüberliegende Wand so dünn ausführt, daß sie unter dem Anpressungsdruck der Klemmschraube elastisch nachgibt. Es werden, hierbei zusätzliche Hilfsmittel völlig vermieden und man erreicht sogar noch gewisse Werkstoffersparnisse.For securing the clamping screws or for securing always perfect contact pressure, even when using aluminum and similar materials, many proposals have already been made. These suggestions almost all point out that you have a resilient part, especially one Spring washer, either between the clamping body and the clamping screw or between never clamping screw and: has switched on the connecting wires. Such constructions are not only expensive, but also often complicated to use, unless special safety measures are taken to prevent it from falling out to prevent the feathers. All of these drawbacks are made according to the invention: thereby avoided that the clamping body consisting of a single part is elastic in itself designed by making the wall opposite the clamping screw so thin executes that it yields elastically under the contact pressure of the clamping screw. Additional aids are completely avoided and one even achieves still certain material savings.

In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstands dargestellt. Der Klemmkörper i, der zur Aufnahme der Anschlußdrähte 2 dient, ist mit seiner der Klemmschraube 3 gegenüberliegenden, vorzugsweise ebenen und nicht keilförmigen Wand 4. so dünn ausgeführt. daß heim Anziehen ,der Klemmschraube 3 die Wand leicht duschgewölbt wird, wie das in der Zeichnung etwas übertrieben dargestellt ist. Die Stärke der Wand a ist so gewählt, daß die Durchwölbun!g elastischer Natur ist, daß also die Wand 4 beim Herausschrauben der Klemmschraube 3 wieder ihre ursprüngliche Farm annimmt.The drawing shows an exemplary embodiment of the subject matter of the invention shown. The clamping body i, which serves to accommodate the connecting wires 2, is with its opposite to the clamping screw 3, preferably flat and not wedge-shaped wall 4. made so thin. that after tightening the clamping screw 3 the wall is slightly arched, as shown in the drawing a little exaggerated is. The thickness of the wall a is chosen so that the arching is of an elastic nature is that so the wall 4 when unscrewing the clamping screw 3 back to its original Farm accepts.

Der von der durchgewölbten Wand .4 auf die Anschlußdrähte 2 ausgeübte Druck wird durch die Anschlußdrähte auch auf die Klemmschraube 3 übertragen. Dadurch wird einerseits verhindert, daß sich die Klemmschraube 3 lockert, und andererseits wird erreicht, daß auch bei einer etwa auftretendem Verformung der Anschlußdrähte 2 noch ein ausreichender Anpressungsdruck auf die Drähte 2 ausgeübt wird, durch den ein Lockerwerden der Anschluß-drähte a verhindert wird.The exerted by the arched wall .4 on the connecting wires 2 Pressure is also transmitted to the clamping screw 3 through the connecting wires. Through this is on the one hand prevented that the clamping screw 3 loosens, and on the other hand it is achieved that even if there is any deformation of the connecting wires 2 a sufficient contact pressure is still exerted on the wires 2 by the loosening of the connecting wires a is prevented.
