Description

Die Erfindung bezieht sich auf eine leitende Verbindung vonAluminiumleitern, insbesondere -seilen, mit einem Messing-, Kupferbolzen od. dgl. Solche Verbindungen; sind bei vielen elektrischen Geräten, bei denen die Wicklung aus Aluminium besteht, erforderlich, um für die Artschlüsse zuverlässige und dauerhafte Verbindungen zu erhalten. Es sind schon verschiedene Verbindungsarten bekannt, die aber meist an. dem eineu oder anderen der folgenden Mängel leiden. Die Verbindungsstelle ist nicht mechanisch genügend fest, der elektrische Kontakt ist nicht dauerhaft, weil das Aluminium-im Laufe der Zeit nachgibt oder sich mit einer isolierenden Oxydschicht überziehen kann. Das Aluminiumleiterende erhält infolge Wärmeeinwirkung, infolge von Schweißung Gußstruktur mit all ihren bekannten Mängeln. Die Verbindung ist nicht genügend korrosionsbeständig oder fällt zu teuer aus bzw. erfordert zu viel Sparmetall. Die Herstellung der Verbindung ist zu umständlich.The invention relates to a conductive connection of aluminum conductors, in particular ropes with a brass, copper bolt or the like. Such connections; are in many electrical devices in which the winding is made of aluminum, required to ensure reliable and permanent connections for the inter-species connections obtain. Various types of connection are already known, but most of them are. suffer from one or the other of the following defects. The junction is not mechanically strong enough, the electrical contact is not permanent because that Aluminum-yields over time or becomes covered with an insulating layer of oxide can cover. The aluminum conductor end is exposed to heat, as a result of weld cast structure with all its known defects. The connection is not sufficiently corrosion-resistant or too expensive or requires too much saving metal. Establishing the connection is too cumbersome.

Erfindungsgemäß werden diese Mängel dadurch vermieden, daß die beiden Teile vorzugsweise mittels Aluminiumspritzguß miteinander verspritzt werden. Die Spritzgußverbindung bildet beispielsweise eine die Leiterenden umgebende Muffe. Aluminiumseil oder -litze wird zweckmäßig vor dem Einspritzen wenigstens über einen Teil seiner eingespritzten Länge durch Pressung verdichtet.According to the invention these shortcomings are avoided in that the two Parts are preferably injected together by means of aluminum injection molding. the An injection-molded connection forms, for example, a sleeve surrounding the conductor ends. Aluminum rope or braid is expediently at least one before injection Part of its injected length is compressed by pressing.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt.An embodiment of the invention is shown in the drawing.

Das bei i ringnutförmig durch Pressung verdichtete .Aluminiumseilende 2 ist mit einem Ansehlußbolzen 3 beispielsweise aus Messing durch eine herumgespritzte Muffe 4 verbunden. Das Bolzenende 5 ist im Ausführungsbeispiel zu einem Vierkant verdickt, um ein festeres Haften im Spritzguß zu erzielen, doch kann die gleiche Wirkung erzielt werden, wenn man in anderer Weise das Bolzenende mit Vor- und Einsprüngen versieht, es also beispielsweise ein- oder mehrfach. anbohrt, Nuten oder Gewinde einschneidet usw. Unter Umständen genügt ein Aufrauhen des einzuspritzenden Endes. Der Muffe 4 kann man. beliebige Gestalt geben, man kamt sie also zylindrisch, kantig od. dgl. ausführen.The aluminum cable end 2, which is compressed in the shape of a ring groove at i, is connected to a connection bolt 3, for example made of brass, by a sleeve 4 molded around it. The pin end 5 is thickened in the exemplary embodiment to form a square, in order to achieve a stronger adhesion by injection, but the same effect can be achieved when you know the pin end with pre- and Einsprüngen otherwise, it thus for example one or more times. Drilled, grooves or threads are cut, etc. Under certain circumstances, it may be sufficient to roughen the end to be injected. The sleeve 4 can be. give any shape, so you came to make them cylindrical, angular or the like.

Die Erfindung bietet namentlich bei Verwendung von. Aluminiumspritzguß den Vorteil, daß sich eine zuverlässige und dauerhafte, mechanisch. und elektrisch einwandfreie Verbindung ergibt, die in ein fachster Weise und rasch in der Massenfertigung hergestellt werden kann. Insbesondere behält der unmittelbar an die Spritzgußmuffe anschließende Teil der Aluminiumleitung seine Biegsamkeit und Festigkeit bei, so daß Leitungsbrüche an der Verbindungsstelle vermieden werden.The invention offers in particular when using. Aluminum injection molding the advantage of being reliable and durable, mechanically. and electric flawless connection results in the most professional way and quickly in mass production can be produced. In particular, it keeps directly to the injection-molded sleeve the subsequent part of the aluminum pipe contributes to its flexibility and strength, so that line breaks at the connection point are avoided.
