Description

Verfahren zur Herstellung von biegsamen Hochfrequenzleitungen Zusatz zum Patent 694 954 In dem Patent 694 9.54 ist ein Verfahren zur Herstellung von biegsamen Höchfrequenzleitungen angegeben, bei denen durch umlaufende Walzen über einem inneren Werkzeug der gerillte Außenleiter hergestellt wird. Durch das innere Werkzeug werden gleichzeitig scheibenförmige Abstandhalter in die gerillte Leitung eingebracht. Gemäß der Erfindung läßt sich mit Hilfe von Kanälen im inneren Werkzeug jedoch auch ein fortlaufender Abstandhalter bzw. eine Isolierung zwischen Innen- und Außenleiter einbringen, während gleichzeitig außen der Rohrleiter geformt und gerillt wird.Process for the production of flexible high-frequency cables addition to the patent 694,954 In the patent 694 9.54 is a method for the production of flexible high-frequency cables specified, in which by rotating rollers over an inner tool of the grooved outer conductor is produced. Through the inside The tool is simultaneously disc-shaped spacers in the grooved pipe brought in. According to the invention can be with the help of channels in the inner tool but also a continuous spacer or insulation between the inner and bring in outer conductor, while at the same time the pipe conductor is shaped and outside is grooved.

In Abb. i ist das innere Werkzeug i eine Hohlwelle, die vorn mit einer Quernut a für die Rillung des Außenleiters 3 versehen ist. Die Welle hat eine ,axiale Bohrung 4 f Abb. a 1 für das Durchführen des Innenleiters und daneben die Bohrung 5 für das Einführen des Isoliermaterials, z. B. einer Spezialkordel 6. Bei Drehung der Welle wird der fadenförmige Abstandhalter durch die Welle gezogen und auf den Innenleiter b schraubenlinienförmig gewickelt, während außen der Außenleiter durch die synchron umlaufenden Walzen 7 in die Quernut :2 eingedrückt und gerillt wird.In Fig. I, the inner tool i is a hollow shaft, which is connected to the front with a Transverse groove a for the grooving of the outer conductor 3 is provided. The shaft has an, axial Hole 4 f Fig. A 1 for the passage of the inner conductor and next to it the hole 5 for the introduction of the insulating material, e.g. B. a special cord 6. When rotating the shaft, the thread-like spacer is pulled through the shaft and onto the Inner conductor b wound helically, while the outer conductor passes through on the outside the synchronously rotating rollers 7 in the transverse groove: 2 is pressed and grooved.

Statt des blanken Innenleiters können auch ein oder mehrere vorisolierte Leiter verwendet werden. Ebenso kann bei entsprechender Ausbildung der Kanäle statt der Kordel auch Masse o. dgl. zwischen Innenleiter und Außenleiter bzw. Mantel eingebracht werden.Instead of the bare inner conductor, one or more pre-insulated conductors can also be used Head can be used. Likewise, can take place with appropriate training of the channels the cord also mass or the like introduced between the inner conductor and outer conductor or sheath will.

Das Verfahren ist auch anwendbar, wenn der Außenleiter aus mehreren in Längsrichtung übereinandergelegten Bändern, z. B. einem Kupferband, einer Lack- oder, Papierzwischenschicht und einem Eisenband, besteht, die zugleich gerillt werden. Eine solche Hülle .aus geschichteten Bändern ist an sich bekannt. Die Herstellung in der bekannten Form aus schraubenlinienförmig gewickelten Bändern ist jedoch übertragungstechnisch ungünstig; ferner lassen sich bei Verwendung eines Dornes und einer Gewindemutter für die Rillung die Abstandhalter nicht gleichzeitig einführen. Beide Nachteile «erden bei dem Verfahren gemäß der Erfindung vermieden.The procedure is also applicable when the outer conductor consists of several in the longitudinal direction superimposed bands, z. B. a copper tape, a lacquer or, paper interlayer and an iron band, which are grooved at the same time. Such a sheath made of layered tapes is known per se. The production in the known form of helically wound strips, however, is transmission technology unfavorable; Furthermore, when using a mandrel and a threaded nut Do not insert the spacers at the same time for the creasing. Both disadvantages «Earth avoided in the method according to the invention.
