Längswasserdichtes HochfrequenzkabelLongitudinally watertight high-frequency cable
Die Erfindung geht von einem längswasserdichten Hochfrequenzkabel aus, dessen kunststoffisolierter Innenleiter koaxial in einem mit Preßsitz auf den Kunststoff gezogenen Außenleiter-Rohr angeordnet ist. ;. "The invention is based on a longitudinally watertight high-frequency cable whose plastic-insulated inner conductor is coaxial is arranged in an outer conductor tube drawn onto the plastic with a press fit. ;. "
Der Erfinimg liegt die Aufgabe zugrunde, solche Hochfrequenz*- kabel für hohe Temperaturänderungen, die sich zwischen minus 20° C bis plus 80° C erstrecken können., betriebssicher zu machen. Bei den bisherigen Ausführungsformen der längswasserdichten Hochfrequenzkabeln mit Ku4tstoffisolierung hat sich gezeigt, daß das metallische Außenleiter-Rohr, z.B. aus Kupfer, bei höheren Temperaturen von z.B. 60° C an der geschweißten oder gelöteten Längsnaht oder in der Nahtzone platzt und damit das Kabel unbrauchbar wird. Diese Art der Zerstörung des Kabels tritt besonders bei Kupferrohren mit dünner Wandstärke auf.The invention is based on the task of such high frequency * - cable for high temperature changes, ranging between minus 20 ° C to plus 80 ° C., Safe to operate do. In the previous embodiments of the longitudinally watertight High frequency cables with plastic insulation has become shown that the metallic outer conductor tube, e.g. made of copper, bursts at higher temperatures of e.g. 60 ° C at the welded or soldered longitudinal seam or in the seam zone and thus the Cable becomes unusable. This type of destruction of the cable occurs particularly with copper pipes with thin walls.
Als Mittel zur Lösung der gestellten Aufgabe ist erfindungsgemäß bei dem eingangs genannten längswasserdichten Hochfrequenzkabel zwischen einer festen Kunststoffschicht und dem Außenleiter-Rohr eine die bei Temperaturänderungen auftretenden Volumenänderungen des Außenleiter-Rohres aufnehmende weicheAccording to the invention, the means for solving the problem posed are in the case of the above-mentioned longitudinally watertight high-frequency cable between a solid plastic layer and the outer conductor tube a soft which absorbs the volume changes of the outer conductor tube that occur when the temperature changes

,Kunststoffschicht vorgesehen., Plastic layer provided.
Diese als Schwartenkonstruktion anzusehende Form der Kunststoffisolierung "besteht zweckmäßigerweise aus einem inneren Kern großen Volumens aus VoIl-PE und einem darüber extrudierten Mantel aus ZeIl-PE. Dabei haftet der Zell-PE-Mantel völlig an dem Kern aus VoIl-PE an. Da andererseits auch das äußere Metallrohr mit'Preßsitz über den Zell-PE-Mantel gezogen ist, besteht volle Längswasserdichtigkeit .in dem Kabel ,für alle Temperaturbereiche, denen das Kabel ausgesetzt ist.This form of plastic insulation, which can be seen as a slab construction "expediently consists of an inner core large volume made of full PE and one extruded over it Sheath made of cell PE. The cell-PE sheath adheres completely the core made of full PE. On the other hand, since the outer metal pipe is also pulled over the cellular PE jacket with a press fit, there is full longitudinal watertightness in the cable, for everyone Temperature ranges to which the cable is exposed.
Die Zell-PE-Schichtdicke ist dabei so zu dimensionieren, daß sie dem Volumenanteil des Voll-PE-Kern angepaßt ist. Auf diese Weise wird ein Aufreißen oder Platzen des Außenleiter-Rohres mit Sicherheit vermieden. .The cell-PE layer thickness is to be dimensioned so that it is adapted to the volume fraction of the full PE core. This prevents the outer conductor tube from tearing open or bursting certainly avoided. .
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt. -An embodiment of the invention is shown in the drawing. -
Ein Querschnitt durch das Hochfrequenzkabel zeigt den Innenleiter 1, der in dem Außenleiter-Rohr 2 koaxial angeordnet ist. Zwischen den beiden Leitern 1 und 2 befindet sich die Kunststoffisolierung, auf der der Außenleiter 2 mit Preßsitz aufgezogen ist. Die Kunststoffisolierung besteht aus dem Kern 3 großen Volumens, z.B. aus VoIl-PE, und dem darüber extrudierten · Mantel 4- aus z.B. ZeIl-PE. Beide Kunststoffteile liegen ebenfalls mit großer Haftung aneinander. Volumenänderungen des Außenleiter-Rohres 2 bewirken ein mehr oder weniger starkes Zusammenpressen oder Ausdehnen des weichen Mantels 4,,ohne daß die Längswasserdichtigkeit des Kabels verloren geht und ohne daß das Außenleiter-Rohr beschädigt wird.A cross section through the high-frequency cable shows the inner conductor 1, which is arranged coaxially in the outer conductor tube 2. Between the two conductors 1 and 2 is the plastic insulation on which the outer conductor 2 is drawn with a press fit is. The plastic insulation consists of the core 3 large volume, e.g. made of full PE, and the extruded over it Sheath 4- made of e.g. cell PE. Both plastic parts are also there with great adhesion to each other. Changes in volume of the outer conductor tube 2 cause a more or less strong compression or expanding the soft sheath 4, without the longitudinal watertightness of the cable being lost and without the outer conductor tube is damaged.
