Description

Verfahren zur Herstellung einer Leiterverbindung für hohe Ströme Die Erfindung betrifft ein Verfahren zur Herstellung einer Leiterverbindung für hohe Ströme sowohl durch Verschrauben als auch durch Verlöten der Leiterenden.Method of making a conductor connection for high currents Die The invention relates to a method for producing a conductor connection for high Currents both by screwing and soldering the conductor ends.

Es ist bekannt, runde Leiterenden unter Verwendung eines Zwischenstückes, mit dem die Leiterenden ihrerseits verschraubt werden, mittelbar gegeneinander zu verschrauben. Hierdurch wird zunächst eine mechanisch feste Verbindung der Leiterenden hergestellt. Danach wird durch Eingießen eines Lötmetalls die elektrische Stromleitung verbessert. Dabei wirken jedoch diejenigen Berührungsflächen, die bereits unter dem Verschraubungsdruck stehen, nicht mit. Die Verbindung kann nach Erwärmen des Lotes gelöst werden. Sie ist aber nur wiederherstellbar, nachdem die einzelnen Teile zuvor sehr sorgfältig vom Lot befreit worden sind.It is known to make round conductor ends using an intermediate piece, with which the conductor ends are screwed in turn, indirectly against each other screw. This initially creates a mechanically firm connection between the conductor ends manufactured. After that, the electric power line is established by pouring a solder improved. However, those contact surfaces that are already under the screw connection pressure, not with. The connection can after heating the Lots to be solved. But it can only be restored after the individual parts have been very carefully removed from the solder beforehand.

Das Verfahren nach der Erfindung besteht demgegenüber darin, daß sich überlappende flache Schienen mit einem Lotauftrag versehen, darauf in an sich bekannter Weise mittels durchgesteckter Schraubenbolzen, deren Köpfe bzw. Muttern mit Tellerfedern od. dgl. unterlegt sind, gegeneinandergepreßt und schließlich bis zum Fließen des Lotes erwärmt werden.The method according to the invention consists in that overlapping flat rails provided with a solder application, on it in a known manner Way by means of threaded bolts, their heads or nuts with disc springs Od. Like. Are underlaid, pressed against each other and finally until the flow of the Solder to be heated.

Dies hat den Vorteil, daß diejenigen Leiterflächen, die unter gegenseitigem Verschraubungsdruck stehen, auch miteinander verlötet werden. Sowohl bezüglich der Verringerung des übergangswiderstandes als auch bezüglich der Lösbarkeit und der Wiederherstellbarkeit der Verbindung wird auf diese Weise ein wesentlicher Fortschritt erzielt.This has the advantage that those conductor surfaces that are under mutual The screw connection pressure can also be soldered together. Both with regard to the Reduction of the contact resistance as well as with regard to the solvability and the Reconnectability in this way becomes a major step forward achieved.

Die Zeichnung zeigt ein Ausführungsbeispiel gemäß der Erfindung.The drawing shows an embodiment according to the invention.

Mit 1 und 2 sind Stromschienen bezeichnet, die durch Schraubenbolzen 3 und Muttern 4 unter Verwendung von Tellerfedern 5 mechanisch verbunden sind. Außerdem erfolgt die elektrische Verbindung durch eine Weichlotschicht 6. 1 and 2 denote busbars which are mechanically connected by screw bolts 3 and nuts 4 using disc springs 5. In addition, the electrical connection is made through a soft solder layer 6.

Die Verbindung wird folgendermaßen hergestellt: Die Enden der angepaßten Leiter 1 und 2 werden mit der Weichlötschicht 6 (z. B. Lötzinn) versehen und unter Verwendung von Bolzen 3, Mutter 4 und Tellerfedern 5 miteinander verschraubt. Danach wird die Verbindungsstelle erwärmt (z. B. Widerstandserwärmung, Lötkolben oder Schweißflamme), so daß das Lot 6 schmilzt und eine innige metallische Verbindung zwischen den Leitern 1 und 2 herstellt.The connection is made as follows: The ends of the matched conductors 1 and 2 are provided with the soft solder layer 6 (e.g. tin solder) and screwed together using bolts 3, nuts 4 and disc springs 5. The connection point is then heated (e.g. resistance heating, soldering iron or welding flame) so that the solder 6 melts and creates an intimate metallic connection between the conductors 1 and 2.

Zwecks Trennung der Verbindung werden die Verschraubungen gelöst, danach wird die Verlötung bis zum Lösen erwärmt. Es kann ein relativ niedrigschmelzendes Lot verwendet werden, da die Lötung von mechanischen Beanspruchungen praktisch frei bleibt.To separate the connection, the screw connections are loosened, then the soldering is heated until it is released. It can be a relatively low melting point Solder can be used as the soldering is practically free from mechanical stresses remain.

Das Verfahren nach der Erfindung eignet sich außer für hochbelastete Stromschienen für die Verbindung von Wicklungsstäben von Transformatoren und Drosselspulen. Die Leiterverbindung kann einen Laeküberzug als Korrosionsschutz erhalten.The method according to the invention is suitable except for highly stressed Busbars for connecting the winding bars of transformers and reactors. The conductor connection can be given a Laek coating as protection against corrosion.
