Sie besteht aus zwei mit unterschiedlich gefärbter Isolierung versehenen elektrischen Adern, die nebeneinander liegend von einer als Trennschicht bezeichneten Umwicklung umgeben sind. Über der Trennschicht liegt ein durch Extrusion erzeugter Innenmantel aus Polyvinylchlorid. Der Innenmantel ist von einem Geflecht aus verzinnten Kupferdrähten umgeben. Als mechanischer Schutz ist ein äußerer Mantel aus Polyvinylchlorid vorgesehen. Der Aufwand zur Herstellung dieser Leitung ist erheblich. Das gilt insbesondere für die Herstellung des aus Adern und Trennschicht bestehenden Kerns. Die Trennschicht muß außerdem für Kontaktierungszwecke gesondert entfernt werden.The known line according to DE 298 08 657 U1 mentioned at the beginning fulfills such Demands as far as possible. It consists of two with different colored insulation provided electrical wires, which lie side by side as a separating layer designated wrapping are surrounded. There is an extrusion over the separation layer generated inner jacket made of polyvinyl chloride. The inner jacket is made of a braid surrounded by tinned copper wires. An outer jacket is made of mechanical protection Polyvinyl chloride provided. The effort to manufacture this line is considerable. This applies in particular to the manufacture of the wire and separation layer Core. The separation layer must also be removed separately for contacting purposes become.

Der Erfindung liegt die Aufgabe zugrunde, die eingangs geschilderte Leitung so zu gestalten, daß sie einfach herstellbar und einfach abzumanteln ist.The invention has for its object to the line described above design that it is easy to manufacture and easy to strip.

Diese Aufgabe wird gemäß der Erfindung dadurch gelöst,

  • daß die gegeneinander isolierten Leiter mit wechselnder Schlagrichtung miteinander verseilt sind,
  • daß der Innenmantel aus mechanisch stabilem aber komprimierbarem Isoliermaterial besteht und
  • daß die Schutzschicht aus einer um den Schirm längseinlaufend herumgeformten ersten Folie und aus einer um die erste Folie wendelförmig herumgewickelten zweiten Folie aufgebaut ist.

  • that the mutually insulated conductors are stranded together with alternating lay direction,
  • that the inner jacket consists of mechanically stable but compressible insulating material and
  • that the protective layer is constructed from a first film which is formed around the screen in a longitudinal direction and from a second film which is wound helically around the first film.

Diese Leitung läßt sich in einem einzigen Arbeitsgang mit der erforderlichen Maßgenauigkeit herstellen. Da die Leiter unter Einhaltung eines isolierenden Abstands mit wechselnder Schlagrichtung miteinander verseilt sind, werden keine in nur einer Richtung rotierenden, mit Spulen bestückten Verseilkörbe benötigt. Der wegen seiner komprimierbaren Ausführung als Polsterschicht wirkende Innenmantel kann mit gegenüber dem Verseilvorgang gleichbleibender Geschwindigkeit auf einfache Weise um die verseilten Leiter herumgeformt werden. Das gilt auch für die im Tandemverfahren anschließend aufzubringenden Schichten "Schirm" und "Schutzschicht". Nach einer für Kontaktierungszwecke durchgeführten Abmantelung sind die Leiter ohne Zusatzmaßnahmen direkt zugänglich, da der Innenmantel nach Durchtrennung direkt von den Leitern abgezogen werden kann.This line can be done in a single operation with the required Establish dimensional accuracy. Because the conductors respect an insulating distance are stranded together with alternating lay direction, none will be in only one In the direction of rotating stranding baskets equipped with coils. The one because of his compressible design as an inner layer acting as a cushion layer compared to the stranding process of constant speed in a simple manner around the stranded conductors. This also applies to those in tandem then layers "screen" and "protective layer" to be applied. After one for The conductors are made without stripping Additional measures directly accessible, since the inner sheath is directly cut can be removed from the conductors.

Eine derartige Verseilung wird in der Fachwelt auch als "SZ-Verseilung" bezeichnet. Im Verlauf der Leitung L ändert sich jeweils an Umkehrstellen U, von denen in Fig. 1 eine gezeigt ist, die Richtung der Verseilung für die Verseilelemente E. Zur Herstellung derartiger Leitungen werden vorteilhafterweise keine in nur einer Richtung drehenden Verseilvorrichtungen benötigt, die in herkömmlicher Technik mit einer der Anzahl der zu verseilenden Elemente entsprechenden Anzahl von Spulen bestückt werden müssen.In Fig. 1 is a schematic side view of the core of an electrical line L with two Shaped stranding elements E shown, which twisted together with changing direction of lay are. Such stranding is also referred to in the technical field as "SZ stranding". In the course of the line L changes at reversal points U, one of which is shown in FIG. 1 is shown, the direction of stranding for the stranding elements E.

    Eine Leitung 1 nach der Erfindung hat gemäß Fig. 2 beispielsweise folgenden Aufbau:According to FIG. 2, a line 1 according to the invention has the following structure, for example:

    Im Kern der Leitung 1 sind zwei Adern 2 und 3 angeordnet, die im SZ-Verfahren miteinander verseilt sind. Jede der Adern 2 und 3 besteht aus einem elektrischen Leiter 4 und einer denselben umgebenden Isolierung 5. Die Leiter 4 bestehen vorzugsweise aus Kupfer. Sie können massiv als Draht oder auch als Litzenleiter ausgeführt sein. Für die Isolierung 5 wird in bevorzugter Ausführungsform aufgeschäumtes Material eingesetzt. Sie kann aber auch massiv ausgeführt sein. Die beiden Adern 2 und 3 sind mit unterschiedlich eingefärbter Isolierung 5 versehen. Als Isoliermaterialien sind beispielsweise Polyethylen und Polypropylen geeignet.At the core of line 1, two wires 2 and 3 are arranged, using the SZ method are stranded together. Each of the wires 2 and 3 consists of an electrical conductor 4 and an insulation 5 surrounding the same. The conductors 4 preferably consist of Copper. They can be solid as a wire or as a stranded wire. For the Insulation 5 is used in a preferred embodiment, foamed material. But it can also be solid. The two wires 2 and 3 are with different colored insulation 5 provided. As insulation materials are for example, polyethylene and polypropylene.

    Die Adern 2 und 3 sind sehr maßgenau hergestellt. Sie haben auf ihrer ganzen Länge einen exakt eingestellten Außendurchmesser, der für beide Adern identisch ist. Nach der SZ-Verseilung haben dieselben eine dem doppelten Außendurchmesser derselben entsprechende Höhe H. Die Höhe H ist entsprechend dem Durchmesser des gestrichelf eingezeichneten Kreises K an jeder Stelle der Leitung 1 - in deren Längsrichtung gesehen - gleichbleibend vorhanden. The cores 2 and 3 are made very dimensionally. They have their full length an exactly set outer diameter, which is identical for both wires. After SZ stranding has the same one twice the outer diameter of the same corresponding height H. The height H corresponds to the diameter of the dashed line drawn circle K at each point of the line 1 - in the longitudinal direction seen - consistently present.

    Um die Adern 2 und 3 herum ist ein aus Isoliermaterial bestehender Innenmantel 6 geformt, der an den Adern 2 und 3 anliegt, die Zwickel zwischen denselben ausfüllt und eine kreisrunde äußere Oberfläche mit einem definierten Radius R hat. Der Abstand der äußeren Oberfläche des Innenmantels 6 vom Kreis K ist rundum gleichbleibend. Der Innenmantel 6 besteht aus einem mechanisch stabilen, aber komprimierbaren Material, beispielsweise aus aufgeschäumtem Polyethylen, Polypropylen oder Silikon. Er kann mittels eines Extruders um die beiden Adern 2 und 3 herumgeformt sein.Around the wires 2 and 3 there is an inner jacket 6 made of insulating material shaped, which bears against the wires 2 and 3, fills the gusset between them and has a circular outer surface with a defined radius R. The distance of the outer surface of the inner shell 6 of the circle K is constant all round. The Inner jacket 6 consists of a mechanically stable but compressible material, for example made of foamed polyethylene, polypropylene or silicone. He can be shaped around the two wires 2 and 3 by means of an extruder.

    In bevorzugter Ausführungsform wird der Innenmantel 6 aus einem in Fig. 3 gezeigten Band 7 aus Schaummaterial, vorzugsweise auf der Basis von Polyurethan, hergestellt, das längseinlaufend zu einem Schlitzrohr 8 (Fig. 4) gebogen und so um die beiden Adern 2 und 3 herumgeformt wird:In a preferred embodiment, the inner jacket 6 is made of one shown in FIG. 3 Band 7 made of foam material, preferably based on polyurethane, which longitudinally bent into a slotted tube 8 (FIG. 4) and thus around the two wires 2 and 3 is molded around:

    Das Band 7 besteht aus einem rechteckigen Streifen 9 aus Schaumstoff, der auf einer Trägerfolie 10 angebracht ist. Die Trägerfolie 10 kann auf einer Seite über die ganze Länge des Bandes 7 unter Bildung einer Lasche 11 hinausragen. Zur Herstellung des Innenmantels 6 wird das Band 7 längseinlaufend zu dem Schlitzrohr 8 geformt, in dem seine beiden Seitenkanten am Schlitz 12 aneinander liegen. Die Lasche 11 ragt über den Schlitz 12 hinaus. Sie liegt im Endzustand außen an der Trägerfolie 10 an und kann mit derselben verklebt sein. Die Außenkontur des Schlitzrohrs 8 hat über seine ganze Länge mit großer Genauigkeit gleichbleibende Abmessungen. Dabei wird der Schaumstoff des Streifens 9 durch die Adern 2 und 3 z. T. erheblich komprimiert. Er legt sich aber ohne Spaltbildung auch in die Zwickel zwischen den beiden Adern 2 und 3.The band 7 consists of a rectangular strip 9 of foam, which is on a Carrier film 10 is attached. The carrier film 10 can on one side over the whole Extend the length of the band 7 to form a tab 11. To make the Inner jacket 6, the band 7 is formed longitudinally into the slotted tube 8 in which its two side edges lie against one another at slot 12. The tab 11 projects over the Slot 12 out. In the final state, it lies on the outside of the carrier film 10 and can also be used the same be glued. The outer contour of the slotted tube 8 has over its entire length consistent dimensions with great accuracy. The foam of the Strip 9 through the veins 2 and 3 z. T. considerably compressed. But he lies down without Gap formation also in the gusset between the two wires 2 and 3.

    Über dem Innenmantel 6 ist bei der in Fig. 2 dargestellten Leitung 1 eine Schirmfolie 13 angebracht, die längseinlaufend mit überlappenden Kanten um den Innenmantel 6 herumgeformt ist. Sie kann mit demselben verklebt sein. Die Schirmfolie 13 ist von einem als Geflecht aus elektrisch gut leitenden Drähten bestehenden, elektrischen Schirm 14 umgeben. Für den Schirm 14 können Kupferdrähte verwendet werden, die auch verzinnt sein können. Über dem Schirm 14 ist eine äußere Schutzschicht 15 angebracht, die aus einer längseinlaufend mit überlappenden Kanten aufgebrachten ersten Folie und einer um dieselbe wendelförmig, mit Überlappung herumgewickelten zweiten Folie besteht. A shielding film 13 is located above the inner jacket 6 in the line 1 shown in FIG. 2 attached, the longitudinally running with overlapping edges around the inner jacket 6 is formed around. It can be glued to the same. The screen film 13 is from one as a braid consisting of electrically well-conducting wires, electrical screen 14 surround. Copper wires, which are also tinned, can be used for the screen 14 could be. An outer protective layer 15 is applied over the screen 14, which consists of a first film applied lengthways with overlapping edges and one around the same helical, wrapped with overlap second film.

    Bei ausreichend dichter Ausführung des Geflechts für den Schirm 14 kann auf die Schirmfolie 13 verzichtet werden. Wenn eine Schirmfolie 13 verwendet wird, kann beispielsweise ein einseitig mit einem Schmelzkleber beschichtetes Aluminiumband eingesetzt werden. Der Schmelzkleber wird durch Wärmezufuhr aktiviert, so daß die Schirmfolie 13 mit dem Innenmantel 6 verklebt und denselben dadurch weiter stabilisiert.With a sufficiently dense design of the braid for the screen 14, the Screen film 13 can be dispensed with. If a screen film 13 is used, can for example an aluminum band coated on one side with a hot melt adhesive be used. The hot melt adhesive is activated by the application of heat, so that the Screen foil 13 glued to the inner jacket 6 and thereby further stabilized the same.

    Die beiden Folien der Schutzschicht 15 bestehen beispielsweise aus einem Material auf Polyesterbasis. Sie sind vorzugsweise einseitig mit einem bei Wärmezufuhr wirksam werdenden Kleber beschichtet. Als Kleber sind beispielsweise Materialien auf Polymerbasis und Schmelzkleber geeignet. Die Klebschicht liegt bei der ersten Folie außen und bei der zweiten Folie innen. Bei Wärmezufuhr werden so einerseits die überlappenden Bereiche der beiden Folien sowie andererseits die beiden Folien miteinander verklebt, so daß sich eine fest zusammenhängende Schutzschicht 15 ergibt.The two films of the protective layer 15 consist, for example, of one material Polyester base. They are preferably unilaterally effective with a supply of heat becoming coated with adhesive. For example, materials are used as an adhesive Suitable for polymer base and hot melt adhesive. The adhesive layer is on the first film outside and with the second film inside. When heat is supplied, the overlapping areas of the two foils and, on the other hand, the two foils glued together so that a firmly connected protective layer 15 results.

    Die Leitung 1 nach Fig. 2 ist mit dem geschilderten Aufbau in ihren Abmessungen derart genau, daß sie beispielsweise mit einem in der DE 195 43 390 C1 beschriebenen Gerät in einem einzigen Arbeitsgang abgemantelt werden kann. Das Messer des Geräts durchdringt die Schichten der Leitung 1 bis zum Kreis K. Nach einer Drehung um 360° können diese Schichten und der verbleibende Rest des Innenmantels 6 von den Adern 2 und 3 abgezogen werden.The line 1 according to FIG. 2 is of such dimensions with the structure described exactly that they are, for example, with a device described in DE 195 43 390 C1 can be stripped in a single operation. The knife of the device penetrates the layers of line 1 up to the circle K. After a rotation of 360 ° these layers and the rest of the inner jacket 6 can be removed from the wires 2 and 3 are subtracted.

    Die Leitung 1 kann in Ergänzung der Ausführungsform nach Fig. 2 gemäß Fig. 5 neben den beiden Adern 2 und 3 zusätzlich Stränge 16 und 17 aus Kunststoff aufweisen, die in den Zwickeln der beiden Adern 2 und 3 angeordnet sind. Sie bestehen vorzugsweise aus geschäumten Material und insbesondere aus hoch aufgeschäumtem Polyethylen oder Polypropylen. Die Stränge 16 und 17 sind mit den Adern 2 und 3 zusammen im SZ-Verfahren verseilt. Der sonstige Aufbau der Leitung 1 nach Fig. 5 ist der gleiche wie der der Leitung 1 nach Fig. 2.The line 1 can in addition to the embodiment of FIG. 2 according to FIG. 5 next the two wires 2 and 3 additionally have strands 16 and 17 made of plastic, which in the gussets of the two wires 2 and 3 are arranged. They preferably consist of foamed material and in particular from highly foamed polyethylene or Polypropylene. The strands 16 and 17 are together with the wires 2 and 3 in the SZ process stranded. The other structure of line 1 of FIG. 5 is the same as that line 1 according to FIG. 2.

    Das gilt im Prinzip auch für die Leitung 1 nach Fig. 6. Bei dieser Ausführungsform sind vier Adern 18, 19, 20 und 21 im SZ-Verfahren miteinander verseilt. Alle vier Adern sind mit einer unterschiedlich gefärbten Isolierung 5 versehen. In principle, this also applies to line 1 according to FIG. 6. In this embodiment four wires 18, 19, 20 and 21 twisted together in the SZ process. All four wires are provided with a different colored insulation 5.

    Bei der Leitung 1 nach den Fig. 7 und 8 sind statt der Adern jeweils blanke Leiter eingesetzt, die wieder als Drähte oder Litzen ausgeführt sein können.7 and 8 are bare conductors instead of the wires used, which can again be designed as wires or strands.

    Bei der Leitung 1 nach Fig. 7 sind zwei Leiter 22 und 23 zusammen mit zwei aus Kunststoff bestehenden Strängen 24 und 25 im SZ-Verfahren verseilt. Der Durchmesser der Stränge 24 und 25 ist größer als der der Leiter 22 und 23. Sie berühren einander, so daß die Leiter 22 und 23 in ihren Zwickeln liegend mit ausreichendem Abstand voneinander gegeneinander isoliert sind. Die Stränge 24 und 25 sind sehr maßgenau ausgeführt. Sie haben beide den gleichen Durchmesser. Durch ihre gemeinsame Höhe wird bei dieser Ausführungsform der Leitung 1 der Durchmesser des Kreises K bestimmt. Die Stränge 24 und 25 sind zur Identifizierung der Leiter 22 und 23 unterschiedlich gefärbt. Sie bestehen vorzugsweise aus Schaumstoff.7 are two conductors 22 and 23 together with two from Plastic strand 24 and 25 stranded in the SZ process. The diameter strands 24 and 25 are larger than conductors 22 and 23. They touch each other, so that the conductors 22 and 23 are in their gussets at a sufficient distance are isolated from each other. The strands 24 and 25 are very dimensionally accurate executed. They are both the same diameter. By their common height the diameter of the circle K is determined in this embodiment of the line 1. Strands 24 and 25 are different for identifying conductors 22 and 23 colored. They are preferably made of foam.

    Bei der Ausführungsform der Leitung 1 nach Fig. 8 sind vier blanke Leiter 26, 27, 28 und 29 zusammen mit vier aus Kunststoff bestehenden Strängen 30, 31, 32 und 33 um einen zentralen, ebenfalls aus Kunststoff bestehenden Kern 34 herum angeordnet. Leiter und Stränge sind wieder im SZ-Verfahren miteinander und um den Kern 34 herum verseilt.8 are four bare conductors 26, 27, 28 and 29 together with four plastic strands 30, 31, 32 and 33 around one central, also made of plastic core 34 arranged around. Head and Strands are again stranded together and around the core 34 in the SZ process.

    Der über Leitern und Strängen liegende Aufbau der Leitung 1 nach den Fig. 7 und 8 entspricht dem der Leitung 1 nach Fig. 2. Die Leitung 1 soll mindestens zwei Leiter bzw. Adern haben. In bevorzugter Ausführungsform sind es zwei oder vier Leiter bzw. Adern.The structure of line 1 lying over conductors and strands according to FIGS. 7 and 8 corresponds to that of line 1 according to FIG. 2. Line 1 should have at least two conductors or Have veins. In a preferred embodiment, there are two or four conductors or wires.
