Description

Die vorliegende Erfindung betrifft eine elektrische Leitung nach dem Oberbegriff des Anspruchs 1.The present invention relates to an electrical line according to the preamble of Claim 1.

Elektrische Leitungen zum Anschluß ortsveränderlicher Stromverbraucher müssen flexibel sein und haben deshalb je nach Anforderung an die Flexibilität einen fein- oder auch feinstdrähtigen Leiter.Electrical cables for connecting portable electricity consumers must be flexible and therefore have a fine or depending on the flexibility requirement fine-wire conductor.

Für die mechanische Beanspruchbarkeit und Flexibilität sind außer der Qualität und dem Durchmesser der Drähte besonders der Verseilaufbau des Leiters von Bedeutung. Je kürzer der Verseilschlag der Litzendrähte und Litzen ist, umso höher sind Beweglichkeit und Biegewechselfestigkeit.For the mechanical strength and flexibility are besides the quality and that The diameter of the wires is particularly important for the stranding structure of the conductor. ever the shorter the stranding of the stranded wires and strands, the higher the mobility and fatigue strength.

Aus der DE-A-25 19 687 ist ein Verfahren zur Herstellung eines Litzenleiters bekannt, bei dem beim Verseilen mehrerer Einzeldrähte miteinander ein Faden aus Glasseidezwirn mit verlitzt wird. Der Faden aus Glasseidezwirn soll die beim starken Verwürgen und bei hohen Fertigungsgeschwindigkeiten auftretenden nachteiligen Beeinflussungen der mechanischen Eigenschaften der Kupferdrähte ausgleichen. Glasseidezwirn hat eine um etwa fünffach höhere Zugfestigkeit als ein weicher Kupferdraht und eine Bruchdehnung von ca. 2 % gegenüber einer mittleren Dehnung von 25 bis 35 % bei Kupferdrähten. Der Faden aus Glasseidezwirn fängt daher alle auftretenden Zugparameter auf, die sowohl bei der Herstellung des Litzenleiters als auch im späteren praktischen Gebrauch auftreten können. Nachteilig bei dieser Lösung ist jedoch, daß der elektrisch leitende Querschnitt des Litzenleiters verringert wird. Vielfach wird auch nicht in Kauf genommen, daß ein nicht metallisches Element in der Litze vorhanden ist.From DE-A-25 19 687 a method for producing a stranded conductor is known from when threading several individual wires together, a thread made of glass fiber twine with being stranded. The thread made of fiberglass thread is said to be used for strong gagging and high production speeds, adverse effects on the balance the mechanical properties of the copper wires. Glass silk twine has one around about five times higher tensile strength than a soft copper wire and an elongation at break of approx. 2% compared to an average elongation of 25 to 35% for copper wires. The Thread made of glass silk thread therefore absorbs all the tensile parameters that occur, both occur in the manufacture of the stranded conductor as well as in later practical use can. A disadvantage of this solution, however, is that the electrically conductive cross section of the stranded conductor is reduced. Often it is not accepted that a there is no metallic element in the strand.

Um die Biegewechselfestigkeit bei Litzen zu erhöhen hat man auch bereits versucht, Leiterdrähte aus einer Kupferlegierung z. B. Kupfer-Cadmium, Kupfer-Silber- oder Kupfer-Zinn-Legierungen einzusetzen, jedoch haben diese Vorschläge sich nur bei sehr begrenzten Leitungstypen durchsetzen können. Darüber hinaus sind sie gegenüber den Standardlitzenaufbauten wesentlich teurer bzw. wesentlich schwieriger herstellbar.In order to increase the flexural fatigue strength of strands, attempts have already been made to Conductor wires made of a copper alloy z. B. copper-cadmium, copper-silver or To use copper-tin alloys, however, these suggestions have only been very successful can enforce limited line types. In addition, they are against the Standard strand structures are much more expensive or much more difficult to manufacture.

Ein anderer Lösungsvorschlag ging dahin, Litzenleiter so aufzubauen, daß um einen hartgezogenen Kupferdraht weiche Kupferdrähte herumgeseilt wurden. Auf diese Weise konnten die Zugfestigkeit, die Biegewechselfestigkeit sowie das Verhalten der Litze beim Crimp-Vorgang verbessert werden. Für extreme Anwendungsfälle konnten diese Litzen jedoch auch nicht überzeugen.Another proposed solution was to build a stranded wire in such a way that one hard drawn copper wire, soft copper wires were roped around. In this way could the tensile strength, the fatigue strength and the behavior of the strand Crimping process can be improved. These strands could be used for extreme applications but also not convincing.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, die bekannten elektrischen Leitungen dahingehend zu verbessern, daß diese gegenüber den bisher bekannten Leitungen eine erheblich höhere Biegewechselfestigkeit bei geringeren Kosten aufweisen.The present invention has for its object the known electrical To improve lines so that these compared to the previously known Cables have a significantly higher fatigue strength at lower costs.

Diese Aufgabe wird durch die im Anspruch 1 erfaßten Merkmale gelöst.This object is achieved by the features covered in claim 1.

Neben den sich aus der Aufgabenstellung direkt ergebenden Vorteilen zeichnet sich die erfindungsgemäße Leitung noch durch eine gegenüber Leitungen aus Kupfer-Cadmiumbzw. Kupfer-Zinn-Legierungen vergleichbare höhere Zugfestigkeit aus. Die elektrische Leitfähigkeit ist nur unwesentlich geringer als bei einer Litze der bekannten Art.In addition to the advantages resulting directly from the task, the line according to the invention by a line made of copper-cadmium or. Copper-tin alloys have comparable higher tensile strength. The electrical Conductivity is only slightly less than with a stranded wire of the known type.

Die Erfindung ist anhand der in den Figuren 1 und 2 schematisch dargestellten Ausführungsbeispiele näher erläutert.The invention is illustrated schematically in FIGS. 1 and 2 Exemplary embodiments explained in more detail.

Jede Ader weist einen Leiter 1a bzw. 2a sowie eine Aderisolierung 1b bzw. 2b auf. Der Mantel 3 ist vorzugsweise ein extrudierter Polyurethanmantel. Die Aderisolierung 1b bzw. 2b kann aus thermoplastischen oder vernetzten Isolierwerkstoffen bestehen. Bevorzugt werden strahlenvernetzes Polyethylen, Polyurethan sowie Zweischichtisolierungen, wie sie beispielsweise in der älteren Anmeldung 100 36 610.4 beschrieben ist.Figure 1 shows a section through an electrical line z. B. a sensor line from there are two wires 1 and 2 and a jacket 3 surrounding wires 1 and 2. each Core has a conductor 1a or 2a and core insulation 1b or 2b. The coat 3 is preferably an extruded polyurethane jacket. The core insulation 1b or 2b can consist of thermoplastic or cross-linked insulating materials.

Der Kerndraht 5 ist aus einem Werkstoff mit hoher Zugfestigkeit und Biegewechselfestigkeit hergestellt. Vorzugsweise wird ein Chrom-Nickel-Stahl mit einer Festigkeit von 1770 N/mm2 eingesetzt.The core wire 5 is made of a material with high tensile strength and flexural fatigue strength. A chromium-nickel steel with a strength of 1770 N / mm 2 is preferably used.

Die Einzeldrähte 7 sind Kupferdrähte, die eine Festigkeit von ca. 280 N/mm2 aufweisen.The individual wires 7 are copper wires which have a strength of approximately 280 N / mm 2 .

Ein in der Figur 2 dargestellter Leiter läßt sich in einem Arbeitsschritt herstellen, in dem zunächst mittels sieben SZ-Verseileinrichtungen die aus Kerndraht 5 und den Kupferdrähten 6 bestehenden Drahtbündel 4 hergestellt werden.A conductor shown in Figure 2 can be produced in one step, in which first by means of seven SZ stranding devices made of core wire 5 and Copper wires 6 existing wire bundles 4 are produced.

Die sieben Drahtbündel 4 werden dann durch einen Verseilnippel hindurchgeführt und auf einen rotierenden Aufwickler aufgespult. Durch die Drehung des Aufwicklers werden die Drahtbündel 4 miteinander zu dem vieldrähtigen Leiter 1 a, 2a verseilt.The seven wire bundles 4 are then passed through a stranding nipple and wound on a rotating rewinder. By rotating the rewinder the wire bundle 4 stranded together to form the multi-wire conductor 1 a, 2a.
