Abstract
Description
In der Kabeltechnik gibt es bekanntlich Koaxialkabel, die eingesetzt werden, wenn höherfrequente Signale übertragen werden sollen. Ein Koaxialkabel weist be kanntlich einen Innenleiter und einen Außenleiter auf. Zwischen dem Innenleiter-und dem Außenleiter befindet sich ein Dielektrikum. Der Innenleiter ist beispiels weise ein Rohr oder ein massiver Draht. Der Außenleiter ist beispielsweise ein Rohr, welches koaxial zum Innen leiter angeordnet ist. Außenleiter und Innenleiter kön nen beispielsweise aus Kupfer oder Aluminium bestehen. Das Dielektrikum kann beispielsweise den gesamten Raum zwischen dem Innenleiter und dem Außenleiter ausfüllen. In diesem Fall hat das Dielektrikum die Gestalt eines rohrförmigen Körpers. Es besteht auch die Möglichkeit, als Dielektrikum scheibenförmige Körper zu verwenden, die sich auf dem Innenleiter befinden und im Abstand voneinander angeordnet sind. Als Material für das Di elektrikum eignen sich beispielsweise Kunststoffe wie z. B. Polyäthylen. Der Außenleiter ist von einem Außen mantel bzw. Schutzmantel umgeben.As is well known, there are coaxial cables in cable technology, which are used when higher frequency signals should be transferred. A coaxial cable shows known to have an inner conductor and an outer conductor. Is located between the inner conductor and the outer conductor a dielectric. The inner conductor is an example wise a tube or a solid wire. The outer conductor is for example a tube which is coaxial to the inside head is arranged. Outer conductor and inner conductor can NEN for example made of copper or aluminum. The dielectric can cover the entire room, for example Fill between the inner conductor and the outer conductor. In this case the dielectric has the shape of a tubular body. There is also the possibility to use disk-shaped bodies as dielectric, which are on the inner conductor and at a distance are arranged from each other. As material for the Di For example, plastics such as plastics are suitable e.g. B. polyethylene. The outer conductor is from an outside coat or protective jacket.
Der Erfindung liegt die Erkenntnis zugrunde, daß bei bekannten Kabeln, wenn sie gebogen werden, Wülste bzw. Wellungen entstehen, die wieder geglättet werden müs sen, wenn Garnituren angebracht werden sollen. Der Er findung liegt die Aufgabe zugrunde, ein Koaxialkabel anzugeben, welches diesen Nachteil nicht aufweist und welches die Bildung von Wülsten vermeidet. Diese Aufga be wird durch ein Koaxialkabel mit den Merkmalen des Anspruchs 1 gelöst. The invention is based on the finding that known cables, if they are bent, beads or Corrugations arise that need to be smoothed out again when fittings are to be attached. The he The task is based on a coaxial cable indicate which does not have this disadvantage and which avoids the formation of ridges. This task be through a coaxial cable with the characteristics of Claim 1 solved.
Die Erfindung findet vorzugsweise bei einem Koaxialka bel Anwendung, welches zur Erhöhung der Zugfestigkeit ein Gitterband aufweist, welches beispielsweise aus Glas oder Glasfaserbündeln besteht.The invention preferably takes place in a coaxial camera bel application, which to increase the tensile strength has a lattice band, which for example consists of There is glass or fiberglass bundles.
Die Erfindung wird im folgenden an einem Ausführungs beispiel erläutert.The invention is based on an embodiment example explained.
Die Fig. 1 zeigt ein Vorprodukt eines Koaxialkabels, welches aus einem Innenleiter 1, einem Dielektrikum 2 und aus einem Außenleiter 3 besteht. Gemäß der Fig. 2 wird auf den Außenleiter 3 der Anordnung der Fig. 1 eine Klebeschicht 4 aufgebracht und anschließend gemäß der Fig. 3 auf die Anordnung der Fig. 2 ein Außenman tel 5 aufextrudiert. Durch die Klebeschicht 4 ist ge währleistet, daß beim fertigen Koaxialkabel der Fig. 3 der Außenleiter 3 mit dem Außenmantel 5 erfindungsgemäß verklebt ist. Fig. 1 shows an intermediate product of a coaxial cable, which consists of a center conductor 1, a dielectric 2 consisting of an outer conductor 3. According to FIG. 2 the arrangement of Figure 1, an adhesive layer 4 is on the outer conductor 3. Deposited and then according to FIG. 3 to the arrangement of Fig. 2 extruded a Außenman tel. 5 Through the adhesive layer 4 ge is ensured that in the finished coaxial cable of FIG. 3, the outer conductor 3 is glued to the outer jacket 5 according to the invention.
Die Fig. 4 zeigt ein weiteres Ausführungsbeispiel der Erfindung, bei dem aus einem Klebeband 6 ein rohrförmi ger Körper 7 hergestellt wird, der dann gemäß der Fig. 5 auf die Anordnung der Fig. 1 aufgebracht wird. Auf den rohrförmigen Körper 7 wird gemäß der Fig. 6 ein gitterförmiger, rohrförmiger Körper 8 aufgebracht, der beispielsweise aus einem Gitterband hergestellt wird, und zwar in der gleichen Weise wie der rohrförmige Kör per 7. Der rohrförmige Körper 8, der beispielsweise aus Glasbündeln besteht, erhöht die Zugfestigkeit des Ko axialkabels. Fig. 4 shows a further embodiment of the invention, in which a tubular body 7 is produced from an adhesive tape 6 , which is then applied according to FIG. 5 to the arrangement of FIG. 1. To the tubular body 7 of Figure 6 is a grid-shaped tubular body 8 is in accordance. Applied, which for example is made of a mesh belt, in the same manner as the tubular Kör per 7. The tubular body 8 , which consists for example of glass bundles, increases the tensile strength of the coaxial cable.
Die Fig. 7 zeigt das fertige Koaxialkabel mit dem Au ßenmantel 5, der beispielsweise auf die Anordnung der Fig. 6 aufextrudiert wird. Beim Koaxialkabel der Fig. 7 ist die wesentliche Bedingung erfüllt, daß der Außenmantel 5 durch den Gitterkörper 8 auf die Klebe schicht durchgreift. FIG. 7 shows the finished coaxial cable with the outer sheath 5 , which is extruded onto the arrangement of FIG. 6, for example. In the coaxial cable of Fig. 7, the essential condition is met that the outer sheath 5 through the grid body 8 passes through to the adhesive layer.
Die Fig. 8 und 9 zeigen ein weiteres Ausführungsbei spiel der Erfindung, bei dem keine gesonderte Klebe schicht oder Klebekörper verwendet wird, sondern bei dem auf die Innenfläche des vorgesehenen Gitterkörpers 8 Klebematerial aufgebracht wird, so daß auf eine ge sonderte Klebeschicht auf dem Außenleiter oder auf ei nem gesonderten Klebekörper in diesem Fall verzichtet werden kann. Das fertige Koaxialkabel, bei dessen Her stellung gemäß der Fig. 8 ein mit Klebematerial verse hener Gitterkörper 8 verwendet wird, zeigt die Fig. 9. FIGS. 8 and 9 show another Ausführungsbei game of the invention, layer in which no separate adhesive or adhesive body is used, but 8 adhesive material is applied in which, on the inner surface of the intended grid body, so that a ge singled adhesive layer on the outer conductor or in this case a separate adhesive body can be dispensed with. The finished coaxial cable, in the manufacture of which, according to FIG. 8, a grid body 8 provided with adhesive material is used, is shown in FIG. 9.
