Description

Rohrförmiger Leiter Es ist bekannt, den rohrförmigen äußeren Leiter oder Schirm von konzentrischen Hochfrequenzkabeln ;aus einem dünnen Metallband herzustellen, dessen Ränder miteinander verfalzt sind. Zur Erhöhung der Biegsamkeit ist der Leiter mit Querrillen versehen.Tubular Conductor It is known the tubular outer conductor or shielding of concentric high-frequency cables; to be made from a thin metal band, the edges of which are folded together. To increase flexibility, the conductor is provided with transverse grooves.

Die Erfindung bezieht sich auf ro-hrfö@rmige Leiteroder Schirme für Luftraumkabel aus zwei oder mehreren vorgeformten Metallbändern, die durch Falze miteinander verbunden und in regelmäßigen Abständen mit Querrillen versehen sind.The invention relates to tubular conductors or screens for Airspace cables made from two or more pre-formed metal strips that pass through folds connected to each other and provided with transverse grooves at regular intervals.

Erfindungsgemäß wird vorgeschlagen, die Biegsamkeit eines derartigen Leiters durch Aussparung der Falze an den Querrillen weiter zu erhöhen, während die Querrillen nur bis an die gefalzten Ränder der Bänder reichen. An den gerillten Stellen sind die benachbarten Bänder also nicht durch Falze miteinander verbunden, sondern stoßen lediglich aneinander. Es ist dabei völlig gleichgültig, ob die Querrillen benachbarter Bänder aneinanderstoßen oder gegeneinander versetzt sind.According to the invention it is proposed that the flexibility of such Further increase the ladder by notching the folds on the transverse grooves while the transverse grooves only extend to the folded edges of the ribbons. On the grooved In some places, the neighboring strips are not connected to one another by folds, but just bump into each other. It is completely irrelevant whether the transverse grooves adjacent bands abut one another or are offset from one another.

Die Biegsamkeit der erfindungsgemäß hergestellten leitenden Hüllen läßt sich dadurch weiter erhöhen, daß die Querrillen, wie bereits vorgeschlagen wurde, mit Schlitzen versehen werden. Ein Ausführungsbeispiel des Erfindungsgedankens ist in der Zeichnung dargestellt. Die mit Querrillen versehenen und zu Rohrhälften vorgeformten Metallbänder acl und a2 sind durch die Falze b, und b2 zu einer -rohrförmigen Hülle verbunden. An den gerillten Stellen sind die beiden Rohrhälften nicht durch Falze verbunden, sondern stoßen dort nur aneinander; die gefalzten Ränder sind an diesen Stellen ausgespart worden.The flexibility of the conductive sheaths made in accordance with the present invention can be further increased by the fact that the transverse grooves, as already proposed be slotted. An embodiment of the inventive concept is shown in the drawing. The cross-grooved and tube halves Preformed metal strips acl and a2 are through the folds b, and b2 to a -tube-shaped Sheath connected. The two pipe halves are not through at the grooved points Folds connected, but only butt against each other; the folded edges are on these places have been left out.

Zur Erhöhung der Biegsamkeit sind in den Querrillen Schlitze c angebracht.To increase flexibility, slots c are made in the transverse grooves.
