Description

Die Erfindung bezieht sich auf eine elektrische Leitung, welche mindestens einen von einer Isolierung umgebenen elektrischen Leiter aufweist, bei welcher über der Isolierung ein elektrisch wirksamer Schirm angebracht ist, der von einer Schicht aus Isoliermaterial umgeben ist ( EP 1 921 635 B1 ).The invention relates to an electrical line which has at least one electrical conductor surrounded by an insulation, in which an electrically effective screen, which is surrounded by a layer of insulating material, is fitted over the insulation ( EP 1 921 635 B1 ).

Derartige elektrische Leitungen werden mit mindestens einem isolierten elektrischen Leiter für unterschiedlichste Anwendungsfälle seit Jahren weltweit eingesetzt. Der elektrisch wirksame Schirm solcher Leitungen besteht überwiegend aus Kupferdrähten, die als Geflecht oder Umseilung um die Isolierung eines Leiters herumgeformt sind. Das Gewicht einer solchen Leitung wird im wesentlichen durch den Leiter und den Schirm bestimmt. Das macht sich beispielsweise bei Kraftfahrzeugen oder Flugzeugen ungünstig bemerkbar, in denen eine größere Anzahl von elektrischen Leitungen vorhanden ist, die beispielsweise in Kabelbäumen oder Kabelsätzen zu Einheiten zusammengefaßt sein können.Such electrical lines are used with at least one insulated electrical conductor for a variety of applications worldwide for years. The electrically effective shield of such lines consists mainly of copper wires, which are formed around as a braid or Umseilung the insulation of a conductor. The weight of such a conduit is determined essentially by the conductor and the screen. This is unfavorable, for example, in motor vehicles or aircraft, in which a larger number of electrical lines is present, which can be summarized, for example, in harnesses or harnesses to units.

Die Hersteller von Kraftfahrzeugen sind seit Jahren bemüht, das Gewicht derselben insgesamt herabzusetzen, um insbesondere den Kraftstoffverbrauch zu reduzieren. Dazu ist es beispielsweise bekannt, Karosserien aus Kunststoff zu verwenden oder für die Leitungen Leiter aus Aluminium bzw. aus einer Aluminiumlegierung einzusetzen. Geschirmte Leitungen mit Leitern, die beispielsweise aus Aluminium bestehen, gehen zum Beispiel aus der eingangs erwähnten EP 1 921 635 B1 hervor.The manufacturers of motor vehicles have been endeavoring for years to reduce their weight overall, in particular to reduce fuel consumption. For this purpose, it is known, for example, to use bodies made of plastic or to use conductors made of aluminum or an aluminum alloy for the lines. Shielded cables with conductors, which consist for example of aluminum, go, for example, from the aforementioned EP 1 921 635 B1 out.

Der Erfindung liegt die Aufgabe zugrunde, das Gewicht einer beispielsweise für den Einsatz in Kraftfahrzeugen bestimmten geschirmten elektrischen Leitung herabzusetzen.The invention has for its object to reduce the weight of a particular example for use in motor vehicles shielded electrical line.

Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, daß der Schirm aus einem Kohlenstofffasern enthaltenden Kunststoff besteht.This object is achieved according to the invention in that the screen consists of a plastic containing carbon fibers.

Ein Kohlenstofffasern enthaltender Kunststoff wird umgangssprachlich als "Carbon" bezeichnet. Diese Kurzfassung wird im folgenden beibehalten. Beim Carbon handelt es sich um einen Faser-Kunststoff-Verbundwerkstoff, bei dem Kohlenstofffasern in eine Kunststoff-Matrix eingebettet sind. Die Matrix kann beispielsweise aus einem Duromer, zum Beispiel Epoxidharz, oder aus einem Thermoplast oder aus Keramik bestehen. Carbon ist thermisch und elektrisch gut leitfähig. Es hat allerdings gegenüber Kupfer eine deutlich geringere elektrische Leitfähigkeit. Diese liegt beispielsweise bei 0,0625 x 106 Sm/m. Die Leitfähigkeit des Carbons ist für eine wirksame Schirmung der umschlossenen Leitung insbesondere im Automobilbereich aber ausreichend. Da das Carbon leichter als Kupfer ist, hat eine mit diesem Material geschirmte Leitung gegenüber einer Leitung mit einem Kupferschirm ein geringeres Gewicht. Dieser Effekt macht sich besonders dann vorteilhaft bemerkbar, wenn eine größere Anzahl von Leitungen in einem Gerät vorhanden ist, insbesondere also bei einem Kraftfahrzeug.A carbon fiber-containing plastic is colloquially referred to as "carbon". This summary is maintained below. The carbon is a fiber-plastic composite material in which carbon fibers are embedded in a plastic matrix. The matrix can for example consist of a duromer, for example epoxy resin, or of a thermoplastic or of ceramic. Carbon is thermally and electrically well conductive. However, it has a significantly lower electrical conductivity compared to copper. This is, for example, 0.0625 × 10 6 Sm / m. The conductivity of the carbon is sufficient for effective shielding of the enclosed line, especially in the automotive sector. Since the carbon is lighter than copper, a shielded with this material line compared to a line with a copper screen has a lower weight. This effect is particularly advantageous when a larger number of lines in a device is present, especially in a motor vehicle.

Das Gewicht der Leitung kann dann weiter verringert werden, wenn die Isolierung des Leiters bzw. der Leiter aus einem aufgeschäumten Kunststoff besteht.The weight of the line can then be further reduced if the insulation of the conductor or the conductor consists of a foamed plastic.

Eine noch weitergehende Verminderung des Gewichts der Leitung ist dann gegeben, wenn als Leitermaterial in bekannter Technik Aluminium oder eine Aluminiumlegierung eingesetzt wird.An even further reduction in the weight of the line is given when aluminum or an aluminum alloy is used as the conductor material in a known technique.

Wenn eine solche Leitung in bevorzugter Ausführungsform im Automobilbau eingesetzt wird, kann die Kontaktierung des Schirms mit Vorteil ohne metallische Kontaktelemente vorgenommen werden, und zwar mittels eines elektrisch leitenden Klebers, durch welchen der Schirm mit vorgegebenen "Erdungsstellen" eines Kraftfahrzeugs verbunden wird, beispielsweise mit der Karosserie desselben.If such a line is used in a preferred embodiment in the automotive industry, the contacting of the screen can be made advantageously without metallic contact elements, by means of an electrically conductive adhesive, through which the screen is connected to predetermined "grounding points" of a motor vehicle, for example with the Body of the same.

Es zeigen:

  • Fig. 1 eine Seitenansicht einer elektrischen Leitung mit abschnittsweise entfernten Schichten.
  • Fig. 2 einen Schnitt durch Fig. 1 längs der Linie II - II.
  • Fig. 3 einen Schnitt durch eine gegenüber den Fig. 1 und 2 abgewandelte elektrische Leitung.
  • Fig. 4 in schematischer Darstellung eine Kontaktstelle für eine Leitung nach den Fig. 1 bis 3.
Show it:
  • Fig. 1 a side view of an electrical line with sections removed layers.
  • Fig. 2 a cut through Fig. 1 along the line II - II.
  • Fig. 3 a cut through one opposite the Fig. 1 and 2 modified electrical line.
  • Fig. 4 in a schematic representation of a contact point for a line after the Fig. 1 to 3 ,

In Fig. 1 ist das Ende einer elektrischen Leitung L dargestellt, die einen elektrischen Leiter 1 aufweist. Der Leiter 1 kann beispielsweise aus Kupfer oder aus Aluminium bzw. aus einer Aluminiumlegierung bestehen. Er kann als Massivleiter, aber auch als Litzenleiter ausgeführt sein, in dem eine Anzahl von aus dem Leiterwerkstoff bestehenden Drähten miteinander verseilt sind. Der Leiter 1 ist von einer aus einem Kunststoff bestehenden Isolierung 2 umgeben. Der isolierte Leiter wird im Folgenden als "Ader A" bezeichnet. Um die Isolierung 2 ist rundherum ein elektrisch wirksamer Schirm 3 angebracht, der von einer Schicht 4 aus Isoliermaterial umgeben ist. Die Schicht 4 dient als Berührungsschutz. Sie kann daher relativ dünn ausgeführt sein. Die Leitung L kann auch mehr als eine mit einem Schirm 3 versehene Ader A aufweisen.In Fig. 1 the end of an electrical line L is shown having an electrical conductor 1. The conductor 1 may for example consist of copper or of aluminum or of an aluminum alloy. It can be designed as a solid conductor, but also as a stranded conductor, in which a number of existing of the conductor material wires are stranded together. The conductor 1 is surrounded by an existing plastic insulation 2. The insulated conductor is hereinafter referred to as "core A". Around the insulation 2, an electrically effective screen 3 is mounted all around, which is surrounded by a layer 4 of insulating material. The layer 4 serves as protection against contact. It can therefore be made relatively thin. The line L may also have more than one provided with a screen 3 core A.

Für die Isolierung 2 und die Schicht 4 geeignete Materialien sind beispielsweise Polyethylen, Polypropylen, Polyvinylchlorid und Polyurethan. Die Schicht 4 kann, wie schon erwähnt, dünn sein. Ihre Dicke wird materialabhängig nach Maßgabe ihrer Abriebfestigkeit eingestellt.For the insulation 2 and the layer 4 suitable materials include polyethylene, polypropylene, polyvinyl chloride and polyurethane. The layer 4 may, as already mentioned, be thin. Their thickness is adjusted depending on the material according to their abrasion resistance.

Der Schirm 3 besteht aus Carbon, mit den im Vorangehenden beschriebenen elektrischen Eigenschaften. Das Carbon liegt beispielsweise in Form von Fasern oder Fäden vor, die mit Vorteil beispielsweise mittels einer handelsüblichen Flechtmaschine als Geflecht oder in anderer Ausführungsform als Umseilung um die Isolierung 2 der Ader A herumgeformt werden können. Es ist auch möglich, aus dem Carbon zunächst ein Band zu formen, das um die Isolierung 2 der Ader A lückenlos oder auch mit Überlappung herumgewickelt werden kann.The screen 3 is made of carbon, with the electrical properties described in the foregoing. The carbon is present, for example, in the form of fibers or threads, which can advantageously be shaped around the insulation 2 of the core A, for example by means of a commercially available braiding machine as a braid or, in another embodiment, as a stranding. It is also possible to first form a band from the carbon, which can be wrapped around the insulation 2 of the wire A gapless or even with overlap.

In einer weiteren Variante kann das Carbon auch als Schlauch vorgeformt werden, in welchen die Ader A eingezogen bzw. hineingeschoben wird. Ein solcher Schlauch kann anschließend durch Zugbelastung bis zur Anlage an der Isolierung 2 der Ader A herunter gezogen werden. Er kann abschließend beispielsweise durch das Auftragen von Epoxidharz oder Polyesterharz verfestigt werden. Die Schicht 4 kann in allen geschilderten Ausführungsbeispielen nach Fertigstellung des Schirms 3 beispielsweise mittels eines Extruders auf denselben aufgebracht werden.In a further variant, the carbon can also be preformed as a tube, in which the wire A is pulled or pushed. Such a hose can then be pulled down by tensile load until it touches the insulation 2 of the core A. It can finally be solidified, for example, by the application of epoxy resin or polyester resin. The layer 4 can be applied to the same in all described embodiments after completion of the screen 3, for example by means of an extruder.

Die Isolierung 2 der Ader A kann massiv ausgeführt sein, so wie es in Fig. 2 dargestellt ist. Sie kann gemäß Fig. 3 aber auch aus einem aufgeschäumten Kunststoff bestehen, beispielsweise aus Polyethylen, das in bekannter Technik chemisch aufgeschäumt werden kann.The insulation 2 of the core A can be made solid, as it is in Fig. 2 is shown. She can according to Fig. 3 but also consist of a foamed plastic, such as polyethylene, which can be chemically foamed in a known technique.

Wenn eine Leitung L beispielsweise in einem Kraftfahrzeug an Masse angeschlossen werden soll, dann braucht an einer entsprechenden Stelle im Verlauf der Leitung L, die gezielt vorgegeben werden kann, nur die Schicht 4 entfernt zu werden. Der Schirm 3 liegt dann an dieser Stelle frei. Er kann danach entsprechend der schematischen Darstellung in Fig. 4 mittels eines elektrisch leitenden Klebers 5 an ein Bauteil 6 des Kraftfahrzeugs angeklebt werden, mit Vorteil an die Karosserie desselben.If a line L is to be connected to ground in a motor vehicle, for example, then only the layer 4 needs to be removed at a corresponding point in the course of the line L, which can be specified in a targeted manner. The screen 3 is then available at this point. He can then according to the schematic representation in Fig. 4 are glued to a component 6 of the motor vehicle by means of an electrically conductive adhesive 5, with advantage to the body thereof.
