Im Zuge der Herstellung des Kabels wird zunächst eine derartige Leitung bereitgestellt. Die Leitung wird abgelängt und der Mantel 5 am Ende der Leitung entfernt. Dieser Schritt wird so vorgenommen, dass danach an dem betreffenden Ende der Leitung der Schirm 3 freigelegt ist.In the course of the production of the cable, such a line is first provided. The pipe is cut to length and the
Darauffolgend wird eine Stützhülse 6 um den Schirm 3 gelegt. Die Stützhülse 6 kann als offene oder geschlossene Hülse ausgestaltet sein, insbesondere als eine offene oder geschlossene Crimphülse gemäß der Definition nach DIN EN 60352-2. In der
Nachdem die Stützhülse 6 um den Schirm 3 gelegt worden ist, wird die Stützhülse 6 verpresst beziehungsweise gecrimpt, so dass die Stützhülse 6 radial außerhalb des freigelegten Schirms 3 am Schirm 3, insbesondere am Drahtgeflecht 3.1, festgelegt ist. Der Außendurchmesser der Stützhülse 6 beträgt hier nur 3 mm.After the
Danach wird der freigelegte Schirm 3 beziehungsweise das zum Ende der Leitung hin aus der Stützhülse 6 herausstehende Ende des Schirms 3, insbesondere des Drahtgeflechts 3.1, umgeschlagen. Im vorgestellten Ausführungsbeispiel wird die Folie 3.2 nicht umgeschlagen.Thereafter, the exposed
Dementsprechend ist dann die Stützhülse 6 innerhalb eines axialen Abschnitts, der sich also entlang der Längsachse A erstreckt, zwischen einer ersten Lage und einer zweiten Lage des Drahtgeflechts 3.1 angeordnet. Die erste Lage des Drahtgeflechts 3.1 ist relativ zur zweiten Lage des Drahtgeflechts 3.1 radial weiter innen liegend angeordnet.Accordingly, the
Als nächstes wird die Isolierschicht 2 am Ende der Leitung entfernt. An der so vorbereiteten Leitung wird ein in den Figuren nicht dargestellter Kontakt befestigt. Insbesondere wird am abisolierten Ende des Innenleiters 1 ein Kontakt fixiert, hier durch einen Crimpprozess. Danach wird der Kontakt in einen dielektrischen, also elektrisch isolierenden, Kontaktträger 7 (
Nachfolgend wird die Hülse 4 um die zweite Lage des Drahtgeflechts 3.1 gelegt. Auch die Hülse 4 kann als offene oder geschlossene Crimphülse ausgestaltet sein, insbesondere gemäß der Definition nach DIN EN 60352-2. Im vorgestellten Ausführungsbeispiel ist auch die Hülse 4 offen und aus elektrisch leitendem Material hergestellt, hier aus Federbronze mit einem E-Modul von 115 GPa.Subsequently, the
Danach wird die Hülse 4 verpresst beziehungsweise gecrimpt, so dass die Hülse 4 am Schirm 3 festgelegt ist. Dadurch, dass das Material beziehungsweise der Werkstoff der Hülse 4 einen geringeren E-Modul aufweist als das Material der Stützhülse 6 kann die Abzugskraft erhöht werden. Zudem kann eine höhere Torsionsbeanspruchbarkeit des Kabels im Bereich der Fügestelle erreicht werden.Thereafter, the
Das Kabel ist nun so ausgestaltet, dass die Hülse 4 einen ersten Abschnitt 4.1, einen zweiten Abschnitt 4.2, einen dritten Abschnitt 4.3 und einen vierten Abschnitt 4.4 aufweist, wobei die Abschnitte in axialer Richtung x aneinandergereiht sind. Der zweite Abschnitt 4.2 ist in axialer Richtung x zwischen dem ersten Abschnitt 4.1 und dem dritten Abschnitt 4.3 angeordnet.The cable is now designed so that the
Der erste Abschnitt 4.1 und der zweite Abschnitt 4.2 umschließen die Stützhülse 6 beziehungsweise sind bezüglich der Stützhülse 6 radial weiter außen angeordnet.The first section 4.1 and the second section 4.2 enclose the
Weiterhin weist der zweite Abschnitt 4.2 eine radiale umlaufende Verengung auf, die durch das Verpressen beziehungsweise Crimpen erzeugt wurde. Die die radiale Verengung weist, wie beispielsweise aus der
Der dritte Abschnitt 4.3 ist derjenige axiale Bereich der Hülse 4, welcher den Mantel 5 umschließt. Durch die Verengung stützt sich die Hülse 4 in axialer Richtung x gegen den Mantel 5 formschlüssig ab.The third section 4.3 is that axial region of the
Durch die V-förmige Längsschnittgeometrie und die damit verbundenen zwei in axialer Richtung x einander gegenüberliegenden konischen Flächen an der Innenseite der Hülse 4 kann ein vergleichsweise großer Toleranzbereich bezüglich der relativen axialen Lage der Hülse 4 einerseits gegenüber dem Mantel 5 und der Stützhülse 6 andererseits zugelassen werden.Due to the V-shaped longitudinal section geometry and the associated two in the axial direction x opposite conical surfaces on the inside of the
Alternativ zum vorgestellten Ausführungsbeispiel kann das Kabel auch so ausgestaltet sein, dass der Schirm 3 beziehungsweise das Drahtgeflecht 3.1 nicht umgeschlagen ist und insbesondere die Hülse 4 dann auch im ersten Abschnitt 4.1 die Stützhülse 6 nicht nur umschließt sondern diese unmittelbar berührt.As an alternative to the presented embodiment, the cable can also be configured such that the
Durch die Erfindung kann ein Kabel hergestellt werden, dass unter anderem trotz vergleichsweise geringem Durchmesser hohe Abzugswerte also hohe erforderliche Kräfte zum Lösen der Verbindung zwischen der Leitung und der Hülse 4 aufweist.The invention makes it possible to produce a cable which, in spite of its comparatively small diameter, has, among other things, high pull-off values, ie high forces required to release the connection between the line and the
