Description

Hohlseile mit einer hohlen, aus einem zylindrisch zusammengebogenen Metallstreifen bestehenden Seele mit darüber verseilten leitenden Drähten sind bekannt. Es ist auch nicht mehr neu, diese Seele aus einem biegsamen Metallschlauch herzustellen.Hollow ropes with a hollow, from a cylindrical bent metal strips consisting of a core with a conductor stranded over it Wires are known. It is also no longer new, this soul from a flexible one Manufacture metal hose.

Demgegenüber besteht die vorliegende Erfindung in einer besonderen Ausgestaltung der Metallseele, damit sie nicht nur eine genügende ίο Zugfestigkeit, sondern gegenüber den bisherigen Ausführungen auch eine bessere Biegsamkeit besitzt. Zu diesem Zwecke ist die Seele mit Schlitzen versehen, die senkrecht zu dem bereits bekannten, parallel zur Rohrlängsachse verlaufenden, geradlinigen Schütz angeordnet sind.In contrast, the present invention consists in a special embodiment of the Metal core so that it not only has sufficient ίο tensile strength, but also compared to the previous Designs also has better flexibility. For this purpose the soul is with Provided slots that are perpendicular to the already known, parallel to the pipe's longitudinal axis extending, rectilinear contactor are arranged.

Der Erfindungsgegenstand ist in der anliegenden Zeichnung schematisch und nur beispielsweise dargestellt.The subject matter of the invention is shown schematically in the accompanying drawing and is only an example shown.

Fig. ι ist ein Schaubild eines Kabels nach der bekannten Ausführung mit der Länge nach geschlitztem Rohr.Fig. Ι is a diagram of a cable according to the known design with the length slotted tube.

Fig. 2 zeigt den geraden, röhrenförmigen Kern 1 mit gemäß der Erfindung quer gerichteten Hilfsschlitzen 5, 6. "Fig. 2 shows the straight, tubular core 1 with transversely directed according to the invention Auxiliary slots 5, 6. "

Wie man aus Fig. 1 erkennt, ist der hohle Kern 1 des Kabels durch ein Rohr gebildet, das gemäß einer Erzeugenden 2-2 aufgeschnitten ist. Um diesen Kern sind die Drähte 3 und 4 beispielsweise in zwei Lagen herumgewickelt. Selbstverständlich muß die Zahl der Lagen sowie die Dicke und der Durchmesser des Rohres den jeweiligen Bedürfnissen, z. B. der zu übertragenden Stromstärke und der durch die Betriebsspannung bestimmten kritischen Spannung bezüglich der zu vermeidenden Koronaerscheinung, angepaßt werden.As can be seen from Fig. 1, the is hollow Core 1 of the cable is formed by a tube which is cut open according to a generating line 2-2. The wires 3 and 4 are wound around this core, for example in two layers. Of course the number of layers and the thickness and diameter of the pipe must meet the respective needs, e.g. B. the one to be transferred Current strength and the critical voltage determined by the operating voltage with regard to the corona phenomenon to be avoided, be adjusted.

Aus Fig. 2 ist ersichtlich, wie erfindungsgemäß durch zusätzlich angebrachte Hilfsschlitze 5, 6 quer zum Längsschlitz 2" entlang einer Erzeugenden die Biegsamkeit des Rohres erhöhtwird unterBeibehaltung einer genügenden Zugfestigkeit der Seele.From Fig. 2 it can be seen how according to the invention by additionally attached auxiliary slots 5, 6 transversely to the longitudinal slot 2 "along a generating line, the flexibility of the pipe is increased while maintaining a sufficient tensile strength of the core.
