Ortsveränderliche Geräte können beispielsweise Kräne, Werkzeugmaschinen und Roboter sein. Die Leitungen müssen mechanisch belastbar sein, mit einer auf lange Zeit gleichbleibenden Biegefestigkeit, beispielsweise beim Einsatz in Energieschleppketten. Sie sollen auch in einem weiten Temperaturbereich flexibel bleiben, der beispielsweise zwischen -40 °C und +80 °C liegt.Such control lines - hereinafter referred to as "lines" - be For example, to connect mobile devices with a voltage or signal source used.

Aus der US 5 834 699 A geht ein hochflexibles elektrisches Kabel für medizinische Abwendungen hervor. Es weist eine Anzahl von isolierten elektrischen Leitern auf, die um ein zentrales Element herumverseilt sind. In den Zwickeln zwischen den Leitern sind isolierte Zugelemente angeordnet. Die Einheit aus Leitern und Zugelementen ist von einer leitfähigen Membran umgeben, über welcher ein Außenmantel angebracht ist.From US 5 834 699 A is a highly flexible electrical cable for medical Disturbances. It has a number of insulated electrical conductors, the are twisted around a central element. In the gussets between the ladders are insulated tension elements arranged. The unit of ladders and tension elements is of surrounded by a conductive membrane, over which an outer jacket is mounted.

Bei der bekannten Leitung nach dem eingangs erwähnten DE 201 09 974 U1 sind in den Zwickeln der Adern Füllelemente aus Kunststoff angeordnet, deren Durchmesser größer als der Durchmesser der Adern ist. Sie sind zusammen mit den Adern verseilt. Für den Mantel ergibt sich eine von den beiden Adern und den beiden Füllelementen gebildete etwa kreisrunde Unterlage. Die im Durchmesser größeren Füllelemente ermöglichen eine Anpassung des Wellenwiderstandes der Leitung an gewünschte Werte. Durch die Verseilung der Adern miteinander sollen die Wirkung von externen Magnetfeldern reduziert sowie die elektromagnetische Verträglichkeit, die Einstrahlfestigkeit und die Störsicherheit erhöht werden. Ein gesonderter, elektrisch wirksamer Schirm ist nicht vorgesehen. Über den Aufbau der elektrischen Leiter der Adern sind der Druckschrift keine Angaben zu entnehmen.In the known line according to the aforementioned DE 201 09 974 U1 are in the Gaps of cores Plastic filler elements arranged whose diameter is larger as the diameter of the wires is. They are stranded together with the wires. For the Jacket results in one of the two wires and the two filling elements formed about circular base. The larger diameter filling elements allow adjustment of the characteristic impedance of the line to desired Values. By stranding the wires together, the effect of external Magnetic fields reduced as well as the electromagnetic compatibility, the Incident resistance and noise immunity are increased. A separate, electric Effective screen is not provided. About the structure of the electrical conductors of Cores are not to be taken from the publication.

Der Erfindung liegt die Aufgabe zugrunde, die eingangs geschilderte Leitung so zu gestalten, daß sie mit wirksamer elektrischer Schirmung ausgerüstet und einfach herzustellen ist sowie auch bei häufiger Biegebeanspruchung eingesetzt werden kann.The invention is based on the object, the above-described line so too Shaping that they are equipped with effective electrical shielding and easy is to produce and can be used even with frequent bending stress.

Diese Aufgabe wird gemäß der Erfindung dadurch gelöst,

  • daß die Leiter der Adern als aus einer Vielzahl von Einzeldrähten bestehende Litzenleiter ausgebildet sind, deren Einzeldrähte von der Isolierung umschlossen sind,
  • daß in mindestens einem der zwischen den beiden Adern befindlichen Zwickel eine aus verzinnten Kupferdrähten bestehende Litze angeordnet ist,
  • daß die Adern und die Litze zu einer Einheit miteinander verseilt sind und
  • daß über der von den Adern und der Litze gebildeten Einheit eine elektrisch gut leitende Schirmlage angebracht ist, die an den Adern und an der Litze anliegt und von dem Mantel umgeben ist.
This object is achieved according to the invention characterized
  • in that the conductors of the cores are in the form of stranded conductors consisting of a multiplicity of individual wires, the individual wires of which are enclosed by the insulation,
  • in that at least one of the gussets located between the two wires is arranged with a strand made of tinned copper wires,
  • that the wires and the strand are stranded together to form a unit and
  • that over the unit formed by the wires and the strand a good electrical conductive shielding layer is attached, which rests against the wires and on the strand and is surrounded by the jacket.

Diese Leitung ist sehr einfach herstellbar, und zwar mit Einsatz von grundsätzlich bekannten, einfach aufgebauten Maschinen und zugehörigen Vorrichtungen, wie beispielsweise Ablauf- und Aufwickeleinrichtungen. Durch das Zusammenwirken von Litze und Schirmlage ergibt sich auf einfache Weise ein elektrisch hochwirksamer Schirm für die Leitung. Wegen der Litze kann die Schirmlage relativ materialarm ausgeführt werden, wodurch einerseits die gute Biegbarkeit der Leitung unterstützt und andererseits die für eine häufige Biegebeanspruchung geforderte Stabilität sichergestellt ist. Die Litze ergänzt außerdem auf der einen Seite der beiden Adern den Querschnitt der Leitung, der bei entsprechender Gestaltung der gegenüberliegenden Seite leicht etwa kreisrund geformt werden kann. This line is very easy to produce, with the use of basically known, simply constructed machines and associated devices, such as For example, drainage and winding devices. Through the interaction of Strand and shielding results in a simple way, an electrically highly effective screen for the line. Because of the strand, the shield layer can be made relatively poor in material which on the one hand supports the good bendability of the pipe and on the other hand, the required for a frequent bending stress stability is ensured. The wire also complements the one side of the two wires Cross-section of the line, the corresponding design of the opposite Page slightly circular in shape.

Zusammen mit einer zweiten Litze aus verzinnten Kupferdrähten oder einem Strang gleicher Abmessungen, die im der Litze gegenüberliegenden Zwickel zwischen den beiden Adern angeordnet werden, kann dieser etwa kreisrunde Querschnitt einfach und sinnvoll erreicht werden.Together with a second strand of tinned copper wires or a strand the same dimensions, the opposite in the strand gusset between the can be arranged two veins, this approximately circular cross-section can be simple and be sensibly achieved.

Die Schirmlage kann aus einem Hybridband mit einer Kunststoffschicht und einer Metallschicht bestehen. Ein solches Hybridband kann überlappend um die Adern und die Litze herumgewickelt sein, und zwar so, daß die Metallschicht an den Adern und insbesondere dicht an der Litze anliegt. Für die Schirmlage kann aber auch ein aus Kunststoff, vorzugsweise aus Polyester, bestehendes, elektrisch leitendes Vliesmaterial verwendet werden, das ebenfalls in Form eines Bandes vorliegt. Auf dem Vliesmaterial wird ein Metall, vorzugsweise Aluminium oder Kupfer, aus der Dampfphase abgeschieden. Es schlägt sich dabei nicht nur auf der äußeren Oberfläche des Vliesmaterials nieder, sondern dringt auch in dasselbe ein und umhüllt dessen innere Fasern, die bekanntermaßen ungeordnet im Vliesmaterial zusammengehalten sind. Das Vliesmaterial ist dann also "durchdringend" beschichtet. Es hat dadurch eine zwar poröse, aber trotzdem nahezu vollständig geschlossene Metallschicht, die eine Bedeckung über den Adern und der Litze der Leitung mit elektrisch wirksamem, metallischem Material von > 85 % ergibt, wenn ein entsprechendes Band überlappend um Adern und Litze herumgewickelt wird.The shield layer can be made of a hybrid tape with a plastic layer and a Metal layer exist. Such a hybrid band can overlap around the veins and be wound around the strand, in such a way that the metal layer on the wires and especially tight against the strand. For the shielding can also be a Plastic, preferably of polyester, existing, electrically conductive nonwoven material used, which is also in the form of a tape. On the fleece material becomes a metal, preferably aluminum or copper, from the vapor phase deposited. It does not just strike on the outer surface of the Nonwoven material down, but also penetrates into the same and envelops the inner Fibers that are known to be held together disorderly in the nonwoven material. The Nonwoven material is then so "penetrating" coated. It has one though porous, but almost completely closed metal layer, the one Covering over the wires and the wire of the wire with electrically effective, metallic material of> 85% results when a corresponding band overlaps wrapped around wires and strand.

    • Die Leitung L nach Fig. 1 hat zwei Adern 1 und 2, die jeweils einen vorzugsweise aus Kupfer bestehenden Litzenleiter 3 aufweisen, welcher von einer Isolierung 4 umgeben ist. Die Adern 1 und 2 sind zusammen mit einer Litze 5 und einem als Füllelement dienenden Strang 6 aus Isoliermaterial zu einer Einheit verseilt. Über der Einheit aus Adern 1 und 2 sowie Litze 5 und Strang 6 ist eine Schirmlage 7 angebracht, welche von einem Mantel 8 aus Isoliermaterial umgeben ist.The line L of Fig. 1 has two wires 1 and 2, each one preferably made of Copper existing stranded conductor 3, which surrounded by an insulation 4 is.

    Die Litzenleiter 3 der Adern 1 und 2 sind beispielsweise aus sieben Einzeldrähten 9 aufgebaut. Es kann aber auch eine andere Anzahl von Einzeldrähten eingesetzt werden, die sich insgesamt stets zu einem möglichst kreisrunden Litzenleiter ergänzen sollen. Das gilt beispielsweise auch für neunzehn Einzeldrähte mit dem Aufbau 1 + 6 + 12, also mit zwölf Einzeldrähten in der Außenlage. Die Einzeldrähte 9 bestehen vorzugsweise aus Kupfer. Sie werden in bekannter Technik beispielsweise miteinander verseilt, so daß sich ein Litzenleiter 3 mit einem aus Fig. 1 ersichtlichen Querschnitt ergibt. Sie können aber auch parallel zueinander liegend zu dem Litzenleiter 3 zusammengefaßt werden, beispielsweise in einem sogenannten Nippel. Der Litzenleiter 3 wird dann einem Extruder zugeführt, in dem die Isolierung 4 auf denselben aufgebracht wird. Die Isolierung 4 besteht vorzugsweise aus einem Polyolefin, beispielsweise aus Polyethylen oder Polypropylen.The stranded conductors 3 of the cores 1 and 2 are, for example, seven individual wires 9 built up. But it can also be used a different number of individual wires which always add up to a stranded conductor that is as circular as possible should. This also applies, for example, to nineteen individual wires with the structure 1 + 6 + 12, so with twelve strands in the outer layer. The individual wires 9 exist preferably made of copper. For example, they become familiar with each other in known technology stranded, so that there is a stranded conductor 3 with an apparent from Fig. 1 cross-section.

Also the individual wires 10 (or possibly multiple wires) can be stranded or parallel to the stranded wire 5 (eg 1 + 6) stranded wire to be summarized running each other.

    Die Adern 1 und 2 sowie die Litze 5 und der Strang 6 werden in einem folgenden Arbeitsgang mit möglichst kurzer Schlaglänge ohne Rückdrehung zu einer Einheit miteinander verseilt, wodurch sich im Querschnitt gemäß Fig. 1 eine etwa kreisförmige Umhüllende mit dem Durchmesser D ergibt. Der Durchmesser D entspricht der Summe der Durchmesser der beiden Adern 1 und 2. Durch die Verseilung werden die für die flexible Leitung L gestellten Anforderungsprofile, wie Biegbarkeit und Bewegungszyklen in einer Schleppkette, erreicht. Die Schlaglänge liegt mit Vorteil zwischen 6 x D und 14 x D, mit dem Durchmesser D der Einheit aus den vier Verseilelementen.The wires 1 and 2 and the strand 5 and the strand 6 are in a following Operation with the shortest possible length without reverse rotation to a unit stranded together, resulting in the cross-section of FIG. 1 is an approximately circular Envelope with the diameter D results. The diameter D corresponds to the sum the diameter of the two wires 1 and 2. By stranding are for the flexible line L demand profiles, such as flexibility and motion cycles in a drag chain, reached. The lay length is between 6 x D and 14 x D, with the diameter D of the unit of the four stranding elements.

    Wenn die Einzeldrähte 9 der Litzenleiter 3 und/oder die Einzeldrähte 10 der Litze 5 nicht miteinander verseilt, sondern parallel zueinander verlaufend zusammengefaßt sind, gilt für den Verseilprozeß von Adern 1 und 2 sowie Litze 5 und Strang 6 der gleiche Sachverhalt, wie oben beschrieben. Auch nach diesem Verseilprozeß, für den vorzugsweise eine Doppelschlagverseilmaschine eingesetzt wird, verlaufen die Einzeldrähte 9 bzw. 10 weiter parallel zueinander. Sie nehmen bei einer Verseilung ohne Rückdrehung exakt die Verseilschlaglänge an.If the individual wires 9 of the stranded conductor 3 and / or the individual wires 10 of the stranded wire 5 not stranded with each other, but are parallel to each other, applies for the stranding of wires 1 and 2 and strand 5 and strand 6 the same Facts, as described above. Even after this stranding process, for the Preferably, a double twist stranding machine is used, run the Individual wires 9 and 10 more parallel to each other.

Dicke liegt vorzugsweise zwischen 50 µm und 100 µm. Für seine Metallisierung wird ein elektrisch gut leitendes Metall verwendet, insbesondere Aluminium oder Kupfer. Das Metall wird für die Metallisierung in den schmelzflüssigen Zustand überführt und aus der Dampfphase auf dem Vliesmaterial abgeschieden. Dabei dringt das Metall auch in das Vliesmaterial ein und umhüllt die dort befindlichen, ungeordnet zusammengehaltenen Fasern. Insgesamt wird auf und in dem Kunststoffvlies eine zwar poröse, aber nahezu geschlossene Metallschicht erzeugt, die eine Bedeckung von > 85 % für die umschlossene Einheit aus Adern 1 und 2 sowie Litze 5 und Strang 6 ergibt.

Er kann mittels eines Extruders aufgebracht werden und besteht beispielsweise aus einem Polyolefin, wie Polyethylen oder Polypropylen, oder aus einem thermoplastischen Elastomer, wie Polyurethan. Vor der Extrusion des Mantels 8 kann auf die Schirmlage 7 eine Heißsiegelschicht aufgebracht werden, um den Mantel 8 mit der Schirmlage 7 zu verkleben. Beim Entfernen des Mantels 8 für Kontaktierungszwecke wird die Schirmlage 7 dann gleichzeitig mit entfernt, so daß eine Schirmerdung direkt über die Litze 5 erfolgen kann.Over the shield layer 7 of the jacket 8 is arranged made of insulating material.
