Description

Es ist bereits vorgeschlagen worden, die Leiter von luftraumisolierten Fernmeldekabeln von der sie umgebenden Kabelhülle durch mit einem oder mehreren radial verlaufenden Schlitzen versehene Abstandkörper zu isolieren, die an den dem Leiter zugekehrten Flächen einen Metallüberzug, insbesondere Silber- und/oder Zinnüberzug haben, der mit dem Kabelleiter verlötet wird. Diese an sich bekannten Abstandkörper brauchen nicht auf den Kabelleiter aufgefädelt zu werden, wie die, die lediglich mit einer dem Durchmesser des Kabelleiters entsprechenden Bohrung versehen sind, sondern sie können während der Anfertigung des Kabels auf die z. B. aus der Verseilmaschine heraustretende, den Kabelleiter bildende Litze fortlaufend in den erforderlichen Abständen übergeschoben und mit ihr durch Tauchlotung verlötet -,werden. So zeigt Abb. i ein in dieser Weise hergestelltes Hochfrequenzkabel mit dem Leiter io, der Kabelhülle 13 und den aus verlustarmem keramischem Werkstoff, z. B. aus Magnesiummetasilikat, bestehenden Abstandhaltern i i, die mit einem radialen Schlitz 12 und an der dem Leiter io zugekehrten Fläche gemäß Abb. 2 mit einem Lötbelag 14 versehen sind.It has already been proposed to isolate the conductors from airspace Telecommunication cables from the surrounding cable sheath through with one or more to isolate radially extending slots provided spacer that is attached to the Conductor facing surfaces have a metal coating, in particular a silver and / or tin coating that is soldered to the cable ladder. These spacers known per se do not need to be threaded onto the cable ladder like those that only do are provided with a hole corresponding to the diameter of the cable conductor, but you can during the manufacture of the cable on the z. B. from the stranding machine protruding, the cable conductor forming strand continuously in the required Distances pushed over and soldered to it by immersion soldering -, are. So shows Fig. I a high-frequency cable made in this way with the conductor io, the Cable sheath 13 and made of low-loss ceramic material, for. B. from magnesium metasilicate, existing spacers i i, which have a radial slot 12 and the one Conductor io facing surface according to Fig. 2 are provided with a solder coating 14.

Nach der Erfindung sind die isolierenden Abstandhalter gemäß Abb. 3 und ,4 mit einem schräg zu ihrer Mittelachse liegenden, zur Einführung dienenden Schlitz versehen, der in seinem weiteren Verlauf in die Mittelöffnung des :Ustandhalters übergeht, Beim Aufreihen auf den Kabelleiter io müssen die Abstandhalter 16 durch eine Schraubbewegung in die richtige, in Abb. q, dargestellte Lage gedreht werden. Diese Ausführung bietet den Vorteil, daß die isolierenden Abstandhalter 16, die auf der dem Leiter io zugekehrten Fläche mit einem Lötbelag versehen sind, vor ihrem Verlöten mit dem Kabelleiter io von diesem nicht abfallen und beim Eintauchen in das Lötzinn nicht abschwimmen können.According to the invention, the insulating spacers according to Fig. 3 and, 4 with an inclined to its central axis, serving for the introduction Slit provided, which in its further course in the central opening of the: Ustandhalter When lined up on the cable ladder io, the spacers 16 must go through a screwing movement into the correct position shown in Fig. q. This embodiment has the advantage that the insulating spacers 16, the are provided with a solder coating on the surface facing the conductor io, in front of their Soldered to the cable conductor io does not fall off this and when immersed in the solder cannot float away.
