Description
Vorrichtung zum lösbaren Verbinden elektrischer Leiter, insbesondere Aluminiumleiter. Vorliegende Erfindung betrifft eine Vor richtung zum lösbaren Verbinden elektrischer Leiter, insbesondere Aluminiumleiter mittels eines Klemmbügels mit Schraube. Aluminium leiter haben bekanntlich die Eigenschaft, dass das Material unter dem Klemmdruck noch längere Zeit nachgibt und erst später eine gewisse Standfestigkeit gewinnt. Zur Erhal tung einer guten Verbindung der Leiter müs sen also die Klemmschrauben von Zeit zu Zeit nachgezogen werden.
Die erfindungsgemässe Vorrichtung benützt einen Klemmbügel, der aus federndem Mate rial besteht und eine Federung in Richtung der Schraubenaxe gestattet.
Die beiliegende Zeichnung zeigt verschie dene Ausführungsbeispiele des Erfindungsge genstandes. In allen Figuren ist 1 der Klemm bügel, 2 die Klemmschraube und 3 ein Lei terstab. Die gestrichelte Linie 4 deutet den mit letzterem zu verbindenden Leiter an. Der Klemmbügel 1 ist auf den Leiterstab 3 auf geschoben. Der Leiter 4 wird in die der Schraube 2 gegenüberliegende Öffnung des Klemmbügels gesteckt und durch Anziehen der Schraube 2 festgeklemmt.
In jedem Falle ist der Klemmbügel 1 nicht starr, sondern in Richtung der Schrau- benaxe federnd ausgebildet, indem er aus federndem Material besteht und ferner so ge staltet ist, dass insbesondere die Seitenwände des Klemmbügels ein Nachfedern beim An ziehen der Schraube 2 gestatten. Zu diesem Zweck weisen gemäss dem Beispiel Fig. 1 die Seitenwände des Klemmbügels Ein- und Aus buchtungen auf.
Man kann die Elastizität vergrössern, wenn man mehrere ineinander geschobene Rohrteile mit in sich geschlosse ner bezw. sich überlappender Wandung ver wendet gemäss den Beispielen Fig. 4 und 5. Bei den Beispielen Fig. 2 und 3 besteht der Bügel aus einem Rohrstück mit in sich ge schlossener bezw. sich überlappender Rohr wand.
Es ist zweckmässig, den Klemmbügel in an sich bekannter Weise mittels eines Halte stückes auf dem Leiterstab 3 so festzuhalten, dass eine Parallelführung des Klemmbügels auf dem Leiterstab 3 in Richtung der Schrau- benaxe gewährleistet ist.
Device for releasably connecting electrical conductors, in particular aluminum conductors. The present invention relates to a device for releasably connecting electrical conductors, in particular aluminum conductors, by means of a clamp with a screw. It is well known that aluminum conductors have the property that the material yields for a long time under the clamping pressure and only gains a certain stability later. To maintain a good connection between the conductors, the clamping screws must be retightened from time to time.
The inventive device uses a clamping bracket, which consists of resilient mate rial and allows a suspension in the direction of the screw axis.
The accompanying drawing shows various exemplary embodiments of the subject invention. In all figures, 1 is the clamping bracket, 2 is the clamping screw and 3 is a Lei terstab. The dashed line 4 indicates the conductor to be connected to the latter. The clamping bracket 1 is pushed onto the ladder bar 3. The conductor 4 is inserted into the opening of the clamping bracket opposite the screw 2 and is clamped by tightening the screw 2.
In any case, the clamping bracket 1 is not rigid, but resilient in the direction of the screw axis, being made of resilient material and also being designed so that in particular the side walls of the clamping bracket allow rebound when the screw 2 is tightened. For this purpose, according to the example of FIG. 1, the side walls of the clamping bracket have indentations and bulges.
You can increase the elasticity if you have several nested pipe parts with closed ner or. overlapping wall ver used according to the examples Fig. 4 and 5. In the examples Fig. 2 and 3, the bracket consists of a piece of pipe with ge closed respectively. overlapping pipe wall.
It is expedient to hold the clamping bracket in a known manner by means of a holding piece on the conductor bar 3 so that a parallel guidance of the clamping bracket on the conductor bar 3 in the direction of the screw axis is guaranteed.
