Description

Verfahren zur elektrisch leitenden Verbindun, von Metallen mit verschiedenem Schmelzpunkt, insbesondere Aluminium und Kupfer Häufig ist es erforderlich, Körper aus Metallen mit verschiedenen Schmelzpunkten miteinander elektrisch leitend zu verbinden. So kann es z. B. erforderlich sein, Leiter aus Aluminium mit Anschlußstücken, z. B. Kabelschuhen, aus Kupfer zu versehen.Process for the electrically conductive connection of metals with various Melting point, especially aluminum and copper Often it is necessary to have body made of metals with different melting points to become electrically conductive with one another associate. So it can be B. be necessary, conductors made of aluminum with connectors, z. B. Cable lugs to be provided from copper.

Gemäß der Erfindung gelingt es, eüie in mechanischer und elektrischer Hinsicht gleicher `'eise befriedigende Verbindung dadurch herzustellen, daß der Körper aus dem Metall niedrigeren Schmelzpunktes, z. B. Aluminium, an der Verbindungsstelle bis zur Knetbarkeit erhitzt und dann der Körper aus dem anderen Metall, z. B. Kupfer, der mit einem konischen steilgängigen Holzgewinde versehen ist, in ihn hineingeschraübt @-,vird.According to the invention it is possible to eüie in mechanical and electrical To establish a satisfactory connection in the same way that the Body made of the metal of lower melting point, e.g. B. aluminum, at the junction Heated to kneadability and then the body made of the other metal, e.g. B. copper, which is provided with a conical steep wooden thread, screwed into it @ -, vird.

Im folgenden werden der Einfachheit halber nur Aluminium und Kupfer als Vertreter der Metalle mit verschiedenen Schmelzpunkten erwähnt, ohne daß selbstverständlich die Erfindung auf diese beschränkt wäre.In the following only aluminum and copper are used for the sake of simplicity mentioned as representatives of metals with different melting points, without being taken for granted the invention would be limited to these.

Falls es sich darum handelt, an einem Aluminiumblock verhältnismäßig großer Abmessungen Kupferkontakte anzubringen, die gegenüber dem Aluminiumblock geringe Abmessungen haben, so genügt es, ohne weitere Vorkehrungen den Aluminiumblock an der entsprechenden Stelle zu erhitzen. Beispielsweise kann der Block vorgebohrt «-erden und das Bohrloch mittels eines Schweißbrenners a. dgl. erhitzt werden.If it is, on an aluminum block proportionally large dimensions to attach copper contacts that are opposite to the aluminum block If the dimensions are small, it is sufficient to use the aluminum block without any further precautions to be heated in the appropriate place. For example, the block can be pre-drilled «-Earth and the borehole using a welding torch a. Like. Be heated.

Handelt es sich dagegen darum, zwei Körper ungefähr gleicher Abmessungen miteinander zu verbinden, z. B. wie das in der Zeichnung dargestellt ist, einen Aluminiumstab i mit einem Kabelschuh oder Anschlußauge z aus Kupfer zu versehen, so ist es erforderlich, den Aluminiumstab in eine zweckmäßig zweiteilige Form 3 aus Eiseii o. dgl. einzusetzen, in der er bis zur Knetbarkeit erhitzt wird. Diese Form besitzt an der entsprechenden Stelle eine Öffnung, durch die das Anschlußauge 3 aus Kupfer, das mit einem Holzge%vinde 4. versehen ist, in den Aluminiumstab eingeschraubt werden kann. Auch in diesem Falle kann der Aluminiumstab mit einer entsprechenden Vorbohrung versehen sein. Zweckmäßig ist es, das an dem Kupfer vorgesehene Holzgewinde mit einem Überzug aus einem :Metall, z. B. Zink, zu versehen, das sich sowohl mit Kupfer als auch mit Aluminium leicht verbindet.If, on the other hand, it is a question of two bodies of approximately the same dimensions to connect to each other, e.g. B. as shown in the drawing, one Aluminum rod i to be provided with a cable lug or connection eye z made of copper, so it is necessary to convert the aluminum rod into an expediently two-part mold 3 from Eiseii o. The like. To use, in which it is heated until kneadable. These Form has an opening at the corresponding point through which the connecting eye 3 made of copper with a wood thread 4. screwed into the aluminum rod can be. In this case, too, the aluminum rod can be fitted with a corresponding Be provided with a pilot hole. It is useful to use the wood thread provided on the copper with a coating of a: metal, e.g. B. zinc, to be provided with both Easily connects copper as well as aluminum.
