Description

Die Erfindung bezieht sich auf Schlitzklemmen für elektrische Leitungen, insbesondere zum Festklemmen von Aluminiumleitungen, mit einem auf den Klemmenkörper aufschiebbaren, die Klemmschraube aufnehmenden Bügel und besteht darin, daß der die Klemmschraube aufnehmende Bügel federnd ausgebildet ist.The invention relates to slot clamps for electrical lines, especially for clamping aluminum cables, with one on the clamp body slidable, the clamping screw receiving bracket and consists in that the the clamping screw receiving bracket is designed to be resilient.

Gegenüber den bekannten Schraubenschlitzklemmen weist die erfindungsgemäße Ausbildung den Vorteil auf, daß der erforderliche Kontaktdruck für die elektrischen Leitungen auch dann gewahrt bleibt, wenn das an sich weiche Material der Aluminiumleiter unter der Wirkung der Klemmschraube nachgibt bzw. die Leiter, wie dies bei den bekannten Schraubenschlitzklemmen infolge des unelastischen Druckes der Klemmschraube auftritt, verformt oder beschädigt werden.Compared to the known screw slot terminals according to the invention Training has the advantage that the required contact pressure for the electrical Cables are preserved even if the inherently soft material is the aluminum conductor yields under the action of the clamping screw or the ladder, as is the case with the known Screw slot clamping occurs as a result of the inelastic pressure of the clamping screw, deformed or damaged.

In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes dargestellt. Es zeigt Abb. i die Schraubenschlitzklemme mit zwei festgeklemmten Leitungen in Seitenansicht, Abb. 2 den Klemmenkörper, Abb. 3 den federnden Bügel mit Klemmschraube in Seitenansicht, Abb.4 und 5 Draufsichten der Abb.2 und 3 und Abb.6 die Schlitzklemme vor dem Anziehen der Klemmschraube.The drawing shows an exemplary embodiment of the subject matter of the invention shown. It shows Fig. I the screw slot terminal with two clamped Leads in side view, Fig. 2 the terminal body, Fig. 3 the resilient bracket with clamping screw in side view, Figures 4 and 5, top views of Figures 2 and 3 and Fig.6 the slot clamp before tightening the clamping screw.

Der Klemmenkörper a ist in bekannter Weise mit einem Schlitz b zur Aufnahme der elektrischen Leitungen g versehen und besitzt eine gegenüber dem Schlitz b erweiterte axiale Bohrung 1v für die Klemmschraube e sowie eine Ringnut f zum Befestigen des Klemmenkörpers an einem Isolierstück. Die Klemmschraube e ist in einer Gewindebohrung des Bügels h verstellbar gehalten, wobei ein Ansatz i am unteren Schraubenende das völlige Herausdrehen der Schraube e aus dem Bügel k verhindert. Die Enden d des erfindungsgemäß federnd ausgebildeten Bügels k sind umgebogen und greifen in seitliche Nuten c des Klemmenkörpers a ein. Sie halten somit den Bügel k mit der Klemmschraube e über der Bohrung h des Klemmenkörpers.The terminal body a is provided in a known manner with a slot b for receiving the electrical lines g and has an enlarged axial bore 1v for the clamping screw e and an annular groove f for fastening the terminal body to an insulating piece compared to the slot b. The clamping screw e is held adjustable in a threaded hole in the bracket h, with a shoulder i at the lower end of the screw preventing the screw e from being completely unscrewed from the bracket k. The ends d of the bracket k, which is designed to be resilient according to the invention, are bent over and engage in lateral grooves c of the clamp body a. You thus hold the bracket k with the clamping screw e above the hole h of the clamp body.

Beim Anziehen der Klemmschraube e biegt sich der federnde Bügel k, wie in Abb. i gezeigt ist, etwas nach oben durch und bewirkt somit einen elastischen Druck der Klemmschraube e auf die in den Klemmenkörper a eingebrachten elektrischen Leitungen ä, so daß auch beim Nachgeben des Leitungsmaterials oder Verformen der Leitungen stets der erforderliche Kontaktdruck gewahrt bleibt.When the clamping screw e is tightened, the resilient bracket k bends, as shown in Fig. i, slightly upwards and thus causes an elastic Pressure of the clamping screw e on the electrical inserted in the terminal body a Lines ä, so that even when the line material yields or deforms Lines, the required contact pressure is always maintained.
