Abstract

Die Erfindung betrifft ein Verfahren zum Herstellen einer Kontaktanordnung, umfassend einen Kontaktträger und ein mit diesem verbundenes Kontaktstück, als Hubleiter oder Festleiter für eine Vakuumschaltröhre, wobei der Kontaktträger aus Kupfer und das Kontaktstück aus einem abbrandfesten elektrisch leitfähigen Material, enthaltend Kupfer und mindestens eine Metallkomponente mit einem Schmelzpunkt oberhalb 1400°C besteht, wobei für das Kontaktstück ein Rohling aus einer gesinterten Metallmatrix, deren Schmelzpunkt oberhalb 1400°C liegt, verwendet wird, und dieser Rohling in eine der kompletten Form der Kontaktanordnung aus Kontaktstück und Kontaktträger, wie einem Hubleiter oder Festleiter entsprechende Gießform eingebracht wird, dann die Gießform mit Kupferpulver aufgefüllt wird und im Vakuum auf die Schmelztemperatur des Kupferpulvers erhitzt wird, wobei ein Teil des schmelzflüssigen Kupfers in den Rohling infiltriert und der verbleibende Teil des schmelzflüssigen Kupfers den Kontaktträger der Kontaktanordnung, wie eines Hubleiters oder Festleiters ausbildet, und die so gebildete einstückige Kontaktanordnung beispielsweise in der Gestalt eines Hubleiters oder Festleiters nach dem Abkühlen und Erstarren aus der Gießform entnommen wird.

Figure 00000001
The invention relates to a method for producing a contact arrangement, comprising a contact carrier and a contact piece connected to it, as a lifting conductor or fixed conductor for a vacuum interrupter, the contact carrier made of copper and the contact piece made of an erosion-resistant, electrically conductive material containing copper and at least one metal component a melting point above 1400 ° C, for which a blank made of a sintered metal matrix is used for the contact piece, the melting point is above 1400 ° C, and this blank in one of the complete form of the contact arrangement of contact piece and contact carrier, such as a lift or fixed conductor appropriate mold is introduced, then the mold is filled with copper powder and heated in vacuo to the melting temperature of the copper powder, with a portion of the molten copper infiltrated into the blank and the remaining part of the molten Ku Bfers forms the contact carrier of the contact arrangement, such as a lifting conductor or fixed conductor, and the one-piece contact arrangement thus formed is removed from the casting mold, for example in the form of a lifting conductor or fixed conductor, after cooling and solidification.
