Description

Das Patent 516482 als Zusatz zu dem Patent 512701 beschreibt ein Verfahren zur Herstellung von Stoßverbindungen in Kabelleitem durch, elektrische Lotung, bei welchem eine die .Stoßstelle dicht umschließende Muffel aus feuerfestem Material verwendet wird, für den Fall, daß die zu verbindenden Leiter verschiedenen Durchmesser aufweisen. Es ist nun.erkannt worden, daß das in dem Patent 516 482 angegebene Verfahren auch, dann angewendet werden kann, wenn es sich um die Verbindung von Leitern aus verschiedenen Metallen handelt. Dieser Fall liegt.z. B. prak-. tisch dann vor, wenn an einen Kabelleiter aus Kupfer ein solcher aus Aluminium angeschlossen werden soll, wobei "infolge der geringeren Leitfähigkeit des Murnmiums der Leiter aus diesem Metall in der Regel einen größeren Querschnitt aufweist als der desThe patent 516482 as an addition to the patent 512701 describes a method for Creation of butt connections in cable conductors, electrical soldering, in which a muffle made of refractory material that tightly encloses the joint is used for the case that the conductors to be connected have different diameters. It is It has now been recognized that the method specified in patent 516,482 was also then applied can be when it comes to the connection of conductors made of different metals. This case lies e.g. B. prak-. table when an aluminum cable ladder is connected to a copper cable ladder should be, where "due to the lower conductivity of the Murnmiums the Conductor made of this metal usually has a larger cross-section than that of the

Kupferleiters. *Copper conductor. *

Die Erfindung· besteht darin, daß beim Herstellen von solchen Stoßverbindungen zwischen Leitern aus Metallen mit verschiedenen Schmelzpunkten die Temperatur bei der Schweißlötung an der Stoßstelle so weit gesteigert wird, daß das Leiterende aus dem Metall mit dem niedrigeren Schmelzpunkt schmilzt, das zweite Leiterende ans dem Metall mit dem höheren Schmelzpunkt jedoch fest bleibt und in das erste zapfenförmig eingedrückt wird. Dadurch werden Verbindungen erzielt, deren Übergangswiderstand praktisch Null ist. Außerdem hat eine solche Stoßstelle eine Zugfestigkeit, die über der der Leiter selbst liegt.The invention consists in the fact that when making such butt joints between Ladders made of metals with different melting points have increased the temperature during the welding process at the joint is that the conductor end melts from the metal with the lower melting point, the second conductor end on the metal with the higher melting point, however, remains solid and is pressed into the first cone-shaped will. This results in connections whose contact resistance is practically zero. Also has such Joint has a tensile strength that is greater than that of the conductor itself.

Die Abbildung zeigt eine Ausführungsform, ι ist das 'eine Leiterende, z. B. ein massiver Draht aus Kupfer; 2 ist das zweite Leiterende, z. B. ein Seil aus Aluminium. Beim Schweißlöten wird das Leiterende 1 so in das Leiterende 2 hmeingedrückt, daß es bei 3 zapfenförmig hineinragt. Dabei wird eine Muffel 4 aus feuerfestem Stoff verwendet, welche die beiden Leiterenden dicht umschließt. Zweckmäßig wird die Muffel mit einem kegelförmigen Hohlraum 5 versehen, der sich mit Lötmetall füllt. Dadurch wird ein stetiger Übergang zwischen den beiden Leiterenden geschaffen und die Bildung von vorstehenden Kanten* vermieden.The figure shows an embodiment, ι is that 'a conductor end, z. B. a massive one Copper wire; 2 is the second end of the conductor, e.g. B. a rope made of aluminum. At the By soldering, the conductor end 1 is pressed into the conductor end 2 in such a way that it is at 3 protrudes in the shape of a cone. A muffle 4 made of refractory material is used, which tightly encloses the two ends of the conductor. The muffle is expediently provided with a conical cavity 5, which fills with solder. This creates a steady transition between the two Ladder ends created and the formation of protruding edges * avoided.
