Description

Klemme für Erdungsrohre und -leitungen mit verschiedenen Durchmessern Den Gegenstand vorliegender Erfindung bildet eine Klemme für Erdungsrohre und -leitungen mit verschiedenen Durchmessern, bei welcher um ein Erdungsrohr ein Metallband gelegt ist, dessen eines Ende mit einer Klemmvorrichtung für den elektrischen Stromleiter verbunden ist, während. das andere Ende mittels einer Aussparung mindestens an einer Nase der Klemmvorrichtung angebracht ist. Nun sind derartige Klemmen bereits angewendet, bei denen eine Schraube, welche die Klemmvorrichtung zusammenklemmt, zugleich auch das bandförmige Organ fest an das Erdungsrohr anzieht.Clamp for earthing pipes and cables with different diameters The subject of the present invention is a clamp for grounding pipes and lines with different diameters, in which a metal band is placed around an earthing pipe is, one end of which with a clamping device for the electrical conductor connected while. the other end by means of a recess at least at one Nose of the clamping device is attached. Now such clamps are already used, in which a screw, which clamps the clamping device together, also at the same time tightly pulls the band-shaped organ to the grounding tube.

Gegenüber diesen bekannten Vorrichtungen weist nun die der Erfindung zugrunde liegende Klemme den Vorteil auf, daß die Klemmvorrichtung aus zwei Klemmbacken besteht, zwischen die der elektrische Stromleiter gelegt ist, und daß ferner die beiden Bandenden an der oberen Klemmbacke befestigt sind. Die untere Klemmbacke hingegen besitzt Gewinde für mindestens eine sich mit ihrer Spitze gegen das Erdungsrohr abstützende Klemmschraube, so daß beim Anziehen von mindestens einer Klemmschraube sowohl das Band als auch der zwischen der Klemmvorrichtung liegende Stromleiter zu gleicher Zeit festgeklemmt werden. Diese Bauart ermöglicht es, daß der Monteur diese Klemme an Erdungsrohren, die oft sehr unzugängig sind, leicht anbringen kann. Der Monteur kann mit einem einzigen Schlüssel die Klemmschraube anziehen, durch welche zu gleicher Zeit sowohl das Band als auch der Stromleiter festgeklemmt werden.Compared to these known devices, that of the invention now has underlying clamp has the advantage that the clamping device consists of two clamping jaws exists, between which the electrical current conductor is placed, and that also the both ends of the tape are attached to the upper jaw. The lower jaw however, has a thread for at least one with its tip against the grounding pipe supporting clamping screw, so that when tightening at least one clamping screw both the tape and the current conductor lying between the clamping device be clamped at the same time. This design allows the fitter this clamp can easily be attached to earthing pipes, which are often very inaccessible. The fitter can tighten the clamping screw with a single wrench which both the tape and the conductor are clamped at the same time.

Der Gegenstand vorliegender Erfindung ist in beiliegender Zeichnung dargestellt, und zwar zeigt: Abb. i ein Rohr mit Klemmvorrichtung in Vorderansicht, Abb. 2 und 3 die Anordnung nach Abb. i in verschiedenen Seitenansichten, Abb. 4 den Grundriß der Anordnung nach Abb. i.The subject matter of the present invention is shown in the accompanying drawing shown, namely: Fig. i a pipe with clamping device in front view, Fig. 2 and 3 the arrangement according to Fig. I in different side views, Fig. 4 the plan of the arrangement according to Fig. i.

Um das Rohr i ist ein biegsames Metallband 2 gelegt, das mit dem einen Ende um die elektrisch gut leitenden Klemmplatten 7, 8 abgebogen und an ihnen befestigt ist. Zwischen den Klemmplatten 7, 8 sind Leitungsdrähte 9, io eingelegt. Der Leitungsdraht io hat größeren Durchmesser als Draht 9. Während die Platte 8 Gewinde für die Schrauben 5, 6 besitzt, hat die Platte 7 Durchgangslöcher für die Schrauben. Letztere stützen sich mit ihren Spitzen auf dem Rohr i ab und bilden eine gute elektrische Verbindung zwischen den Leitungsdrähten 9, io und dem Rohr i. Die Klemmvorrichtung 7, 8 hat einen Ansatz 3. Das eine Ende des Bandes 2 -ist mit verschiedenen Aussparungen 1i, 12 versehen, so daß es auch bei verschiedenen Durchmessern des Rohres r an dem Ansatz 3 eingehängt werden kann.To the tube i a flexible metal band 2 is placed, which with one The end is bent around the electrically conductive clamping plates 7, 8 and attached to them is. Line wires 9, io are inserted between the clamping plates 7, 8. The lead wire io has a larger diameter than wire 9. While the plate has 8 threads for the screws 5, 6, the plate has 7 through-holes for the screws. Support the latter their tips on the tube i and form a good electrical connection between the lead wires 9, io and the tube i. The clamping device 7, 8 has an approach 3. One end of the band 2 -is with different recesses 1i, 12 provided so that it can also be used for different Diameter of the pipe r can be attached to the approach 3.

Das Anpassen der Klemmvorrichtung erfolgt nun in folgender Weise: Das bandförmige Organ 2 wird über die Klemmplatten 7, 8 gelegt, und zwar so, daB die Schrauben 5, 6 durch die Löcher des Bandendes gehen. Die Schrauben werden in die Platte 8 eingeschraubt. Da gewöhnlich das Rohr, um welches die Klemmvorrichtung gelegt werden soll, an einem schwer zugängigen Orte liegt, ist es von Vorteil, daß die nun folgende Arbeit der Befestigung der Klemmvorrichtung an dem Rohr möglichst einfach ist. Das bandförmige' Organ 2 wird um das Rohr und die Aussparung t2 über den Ansatz 3 gelegt. Jetzt wird mindestens der eine Leitungsdraht (g oder zo) zwischen die Klemmplatten 7, 8 gelegt. Darauf werden die Schrauben 5, 6 angezogen, wobei sie sich gegen das Rohr r abstützen und gleichzeitig das Band 2 zur festen und innigen Anlage an das Rohr r bringen. Infolge der Spannwirkung des Bandes und der Schrauben wird hierbei der Leitungsdraht zwischen den Klemmplatten 7, 8 gut festgeklemmt. Das Befestigen des freien Endes 4 des Bandes 2 kann auch in anderer Weise geschehen, als dargestellt.The adjustment of the clamping device is now carried out in the following way: The band-shaped organ 2 is placed over the clamping plates 7, 8 in such a way that the screws 5, 6 go through the holes in the end of the tape. The screws are in the plate 8 screwed in. Since usually the pipe around which the clamping device is to be placed in a hard-to-reach place, it is advantageous that the now following work of attaching the clamping device to the pipe as possible is easy. The band-shaped 'organ 2 is around the tube and the recess t2 over the approach 3 placed. Now at least one lead wire (g or zo) is between the clamping plates 7, 8 placed. The screws 5, 6 are then tightened, with they support themselves against the tube r and at the same time the band 2 for firm and intimate Bring the system to the pipe r. As a result of the tensioning effect of the belt and the screws the lead wire is firmly clamped between the clamping plates 7, 8. The attachment of the free end 4 of the tape 2 can also be done in another way, as shown.
