Description

Federnde Klemme für Aluminiumleiter Die bei Kupferleitungen gebräuchlichen Klemmen lassen sich bei Aluminiumleitungen nicht ohne weiteres verwenden, wenn sie aus Aluminium nach den gleichen Konstruktionsgrundsätzen gebaut werden; wie sie für Kupferleitungen gelten. Das liegt daran, daß die Flächenpressung bei diesen Aluminiumverbindungsstücken zu klein ist und sich im Laufe der Zeit Übergangswiderstände bilden, die zu Wackelkontakten und Verbrennungen Anlaß geben.Spring-loaded clamp for aluminum conductors The common ones for copper lines Clamps cannot easily be used with aluminum cables if they are made of aluminum according to the same construction principles; as apply to copper cables. This is because the surface pressure in these Aluminum connection pieces are too small and contact resistance increases over time which can lead to loose contacts and burns.

Die Verbindungsklemmen müssen daher anders bemessen und nach ihrer Montage wenigstens einmal nachgesehen und nackigezogen werden, um gute Kontaktstellen zu erhalten.The connecting terminals must therefore be sized differently and according to their Assembly must be checked at least once and stripped bare to ensure good contact points to obtain.

Es ist auch bereits bekannt, in eher Verbindungsklemme eine Feder anzuordnen; um das in der Verbindungsklemme liegende Klemmstück unter dem Einfluß der Feder mitzunehmen. Dabei erhält man aber infolge der bekannten Materialermüdung bei Federn keinen auf die Dauer ausreichenden Flächendruck: Erfindungsgemäß werden diese Schwierigkeiten überwunden, wenn die Klemmvorrichtungen derart ausgebildet werden, daß die Berührungsflächen der miteinander verbundenen Teile ständig unter einem durch Elastizitätskräfte hervorgerufenen Druck gehalten werden, der dadurch erzeugt wird, daß man in die Klemme eine allseitig geschlossene; zusammendrückbare Kapsel K aus elastischem Material (Metall) einbaut, die-Luft in verdichtetem Zustande enthält. Dabei ist es zweckmäßig, die Anordnung so zu wählen, daß der spezifische Flächendruck 0,5 kg pro mm2 beträgt.It is also already known to arrange a spring in rather a connecting terminal; in order to take along the clamping piece located in the connecting terminal under the influence of the spring. However, due to the known material fatigue in springs, the surface pressure is not sufficient in the long term: According to the invention, these difficulties are overcome if the clamping devices are designed in such a way that the contact surfaces of the interconnected parts are constantly held under a pressure caused by elastic forces that is generated thereby becomes that one is in the clamp a closed on all sides; Builds compressible capsule K made of elastic material (metal), which contains air in a compressed state. It is useful to choose the arrangement so that the specific surface pressure is 0.5 kg per mm 2.

Abb. z stellt beispielsweise eine bekannte Klemmvorrichtung mit konusartig ausgebildeten Klemmstücken dar, wie sie bisher im wesentlichen für Freileitungen üblich gewesen ist. Unter der Wirkung der Zugkräfte klemmen ` sich die Drähte des Seils mit den Konen an der Hülsenwandung fest. Diese Klemme ist bei solchen Leitungen nicht anwendbar, deren Seile nicht unter Zugwirkung stehen. Nach der Erfindung wird eine allseitig geschlossene, mit verdichteter Luft gefüllte, dehnbare und zusammendrückbare Kammer K derart angeordnet, daß die Kammerwandungen auf die -anliegenden Konusfiächen ständig einen Drück ausüben.Fig. Z shows, for example, a known clamping device with cone-like formed clamping pieces, as they were previously essentially for overhead lines has been common. Under the effect of the tensile forces, the wires of the Rope with the cones on the sleeve wall. This clamp is on such lines not applicable if the ropes are not under tension. According to the invention one that is closed on all sides, filled with compressed air, stretchable and compressible Chamber K arranged in such a way that the chamber walls rest on the adjacent conical surfaces constantly exerting pressure.

Abb. a zeigt eine Ausführungsform der mit der verdichteten Luft gefüllten Kapsel K im Schnitt. Die Kapsel besteht aus einem an den Enden geschlossenen Federrohr. Das eine Rohrende enthält ein in das Federöhr hineinreichendes Ventil, das wie die bekannten Automobilschlauchventile gestaltet ist. Dieses Rohrende ist mit einem aufschraubbaren Deckel D abgeschlossen.Fig. A shows an embodiment of the filled with the compressed air Capsule K in section. The capsule consists of a spring tube closed at the ends. One end of the tube contains a valve which extends into the spring eye and which, like the known automotive hose valves is designed. This end of the pipe is with a screw-on lid D completed.
