Description

Zugentlastungsklemme für elektrische Kabel Die Erfindung bezieht sich auf eine Zugentlastungsklemme für elektrische Kabel, bestehend aus zwei ineinandersteckbaren, beidseitig durch Zahngesperre verbundenen, das Kabel mittels zahnartigen Stegen, einklemmenden Teilen, von denen der eine starr und der andere elastisch ausgebildet ist.Electrical Cable Strain Relief Clamp The invention relates to on a strain relief clamp for electrical cables, consisting of two interlocking, connected on both sides by a ratchet, the cable by means of tooth-like webs, clamping parts, one of which is rigid and the other is elastic is.

Bei bekannten Klemmen dieser Art können mit ein und demselben federnden Zugentlastungsteil keine unterschiedlichen Kabeldurchmesser eingeklemmt werden, weil ein größerer Durchmesser das federnde Zugentlastungsteil spreizen würde. Bei bekannten Zugentlastungsklemmen mit einseitigem Zahngesperre wird das eingesteckte Teil unter dem Außendruck immer bestrebt sein, sich auf der gesperrelosen Seite aus dem Gegenstück herauszuziehen.In known clamps of this type can be resilient with one and the same Strain relief part no different cable diameters are clamped, because a larger diameter would spread the resilient strain relief part. at known strain relief clamps with one-sided ratchet is the plugged in Part under the external pressure always strive to be on the locked side to pull out of the counterpart.

Demgegenüber besteht die wesentliche Aufgabe der Erfindung darin, eine Zugentlastungsklemme zu schaffen, die es gestattet, Kabel unterschiedlichen Durchmessers sozusagen durch selbsttätige Anpassung der Klenunteile an den Kabeldurchmesser zuverlässig zu fassen. Erfindungsgemäß wird dies dadurch erreicht, daß am starren Teil die Verzahnung keilförmig, in Eindrückrichtung sich verengend, ausgebildet ist. Die Anordnung ist einfach und betriebssicher und erleichtert das Einstecken und Entlasten von Kabeln verschiedener Durchmesser.In contrast, the essential object of the invention is To create a strain relief clamp that allows different cables Diameter, so to speak, by automatically adapting the Klenun parts to the cable diameter to grasp reliably. According to the invention this is achieved in that the rigid Part of the toothing is wedge-shaped, narrowing in the push-in direction is. The arrangement is simple and reliable, and makes plugging in easier and relieving cables of different diameters.

In der Zeichnung ist ein Ausführungsbeispiel gemäß der Erfindung dargestellt, und zwar eine Zugentlastungsklemme 1 mit einem starren Unterteil 2 und einem federnd elastischen Oberteil 3. Beide haben Stege 4 quer zu dem nicht dargestellten Kabel, die miteinander auf Lücke stehen. Ober- und Unterteil sind an den zugekehrten Schmalseiten mit einer Verzahnung 5 versehen, die im Unterteil 2 keilförmig verengt in Eindrückrichtung ist und das Oberteil 3 je nach Kabelstärke verrastet.In the drawing, an embodiment according to the invention is shown, namely a strain relief clamp 1 with a rigid lower part 2 and a resilient upper part 3. Both have webs 4 transversely to the cable, not shown, which are mutually spaced apart. The upper and lower part are provided with a toothing 5 on the facing narrow sides, which in the lower part 2 is narrowed in a wedge shape in the push-in direction and the upper part 3 latches depending on the cable thickness.

Kabel mit verschiedenen Durchmesser werden zwischen den Backen verklemmt und gegen Zug entlastet, indem die Schenkel des elastischen Teiles 3 mehr oder weniger zusammengedrückt werden. Das Unterteil 2 läßt sich insbesondere dem Unterteil eines längsgeteilten Gehäuses für einen Schalter anformen oder in dieses einsetzen. Das Oberteil 3 der Zugentlastung hat Spiel gegen das Oberteil des Gehäuses und gestattet eine schraubenlose Zugentlastung für Kabel verschiedener Stärke in Einbauschaltern.Cables with different diameters are clamped between the jaws and relieved of tension in that the legs of the elastic part 3 are more or less compressed. The lower part 2 can in particular be molded onto the lower part of a longitudinally divided housing for a switch or inserted into it. The upper part 3 of the strain relief has play against the upper part of the housing and allows screwless strain relief for cables of different thicknesses in built-in switches.
