Description
Zum Herstellen von Kontaktkörpern für elektrische Zwecke ging man bisher so vor, daß der eigentliche Kontakt, der beispielsweise aus Wolfram besteht, und der der Befestigung am Träger dienende Nietsteg voneinander gesondert hergestellt und dann in einem weiteren Arbeitsgang durch Löten miteinander verbunden wurden. Hierdurch entsteht ein Körper, wie er in der Fig. i der Zeichnung schematisch gezeichnet ist. Der Teil a stellt den eigentlichen Kontakt dar, während der Teil b den Nietsteg, der beispielsweise aus Eisen besteht, bildet. Dazwischen befindet sich das Kupferlot c, durch das die Teile a. und b zu einem Ganzen verbunden werden.To manufacture contact bodies for electrical purposes, the previous approach was that the actual contact, which consists of tungsten, for example, and the rivet web used to fasten it to the carrier were manufactured separately from one another and then connected to one another by soldering in a further operation. This creates a body as shown schematically in FIG. 1 of the drawing. Part a represents the actual contact, while part b forms the rivet web, which is made of iron, for example. In between is the copper solder c, through which the parts a. and b be combined into a whole.
Durch die Erfindung wird nun ein Kontaktkörper vorgeschlagen, der einen wesentlich einfacheren Aufbau besitzt und somit auch leichter, schneller und billiger hergestellt werden kann. Bei dem neuen Kontaktkörper i,st das Material des eigentlichen Kontaktteiles nur schwer mit dem Material des diesen tragenden Nietsteges legierbar. Die Herstellung geschieht nun erfindungsgemäß derart, daß zwischen beide Teile eine Zwischenischicht aus einem sich mit den Materialien beider Teile weitgehend mischenden Material eingefügt wird, und daß alle drei Teile nach Übereinanderschichten der drei Pulverarten zusammengepreßt werden, wonach der so erhaltene Preßling gesintert wird.The invention now proposes a contact body which has a much simpler structure and thus also lighter, faster and can be produced cheaper. In the case of the new contact body i, st the material the actual contact part difficult with the material of this supporting The rivet bar can be alloyed. The production now takes place according to the invention in such a way that between the two parts an intermediate layer of one with the materials of both Parts largely mixing material is inserted, and that all three parts after Layers of the three types of powder are pressed together, after which the so obtained compact is sintered.
Der neue Kontakt ist in der Fig. 2 wiedergegeben, in der a: bzw. b wiederum den eigentlichen Kontaktteil bzw. den Nietsteg darstellen. Die Verbindung zwischen diesen beiden Teilen ist hierbei durch die metallische Zwischenschicht d gesichert.The new contact is shown in FIG. 2, in which a: or b again represent the actual contact part or the rivet web. The connection between these two parts is here by the metallic intermediate layer d secured.
Die Herstellung des neuen Körpers erfolgt nun so, daß in die Preßform zunächst das Pulver für den Nietsteg, beispielsweise Eisen, hierauf das Pulver für die Zwischenschicht, z. B. Nickel, und schließlich das eigentliche Kontaktpulver, beispielsweise Wolfram, eingebracht wird. Der Körper wird dann in nur einem einzigen Arbeitsgang zu einem einheitlichen Ganzen verpreßt "und schließlich gesintert.The production of the new body is now carried out in such a way that in the mold first the powder for the rivet web, for example iron, then the powder for the intermediate layer, e.g. B. Nickel, and finally the actual contact powder, for example tungsten is introduced. The body then turns into just one Operation "pressed into a uniform whole" and finally sintered.
Es ist selbstverständlich möglich, statt der genannten Metalle auch andere hierfür geeignete Materialien zu verwenden. Beispielsweise kann der eigentliche Kontaktteil auch aus einer Wolfram-Nickel-Legierung mit oder ohne Kupferzusatz oder auch aus Molybdän bestehen. In letzterem Fall kann man für die metallische Zwischenschicht an Stelle von Nickel beispielsweise Kobalt verwenden.It is of course possible, instead of the metals mentioned to use other suitable materials. For example, the actual Contact part also made of a tungsten-nickel alloy with or without the addition of copper or also consist of molybdenum. In the latter case, you can use the metallic intermediate layer instead of nickel, use cobalt, for example.
