Description
leitfähiger Folieconductive foil
Die vorliegende Erfindung betrifft eine Vorrichtung zum Leiten von elektrischem Strom nach dem Oberbegriff des Anspruches 1. Gattungsgemäße Vorrichtungen werden beispielsweise in Flachbandkabeln für die Automobil- oder Flugzeug-Industrie benutzt.The present invention relates to a device for conducting electrical current according to the preamble of claim 1. Generic devices are used, for example, in ribbon cables for the automobile or aircraft industry.
Bekannt sind Flachbandkabel, bei welchen mehrere langgestreckte, parallel zueinander verlaufende Drähte zwischen zwei isolierenden Kunststoff-Folien angeordnet sind. Nachteilig ist hierbei, daß solche Flachbandkabel relativ steif sind.Flat ribbon cables are known in which several elongated wires running parallel to one another are arranged between two insulating plastic films. The disadvantage here is that such flat ribbon cables are relatively stiff.
Weiterhin sind gedruckte Leiter auf Kunststoff-Folien bekannt. Diese sind jedoch einer mechanischen Wechselbeanspruchung nicht gewachsen.Printed conductors on plastic foils are also known. However, these cannot withstand alternating mechanical stress.
Es ist weiterhin bekannt, Flachbandkabel mit Leitern aus sehr flachem Kupferblech herzustellen. Problematisch ist hierbei, daß die Ränder des Bleches die Isolationsfolie des Flachbandkabels verletzen können. Entgratet man die Ränder der Bleche, so ist ihr Preis durch die aufwendige Herstellung sehr hoch.It is also known to produce ribbon cables with conductors made of very flat copper sheet. The problem here is that the edges of the sheet can damage the insulating film of the ribbon cable. If the edges of the sheet are deburred, the cost is very high due to the complex manufacturing process.
Die vorliegende Erfindung betrifft eine Vorrichtung zum Leiten von elektrischem Strom nach Anspruch 1. Ein Ersatz massiver, gewalzter oder gedruckter Leiter durch eine elektrisch leitfähige Folie vereinigt Flexibilität, Belastbarkeit und Bezahlbarkeit des Kabels. Eine Vorrichtung nach Anspruch 2 oder 3 gestattet eine kostengünstige Fertigung des Flachbandkabels.The present invention relates to a device for conducting electrical current according to claim 1. Replacing solid, rolled or printed conductors with an electrically conductive foil combines flexibility, resilience and affordability of the cable. A device according to claim 2 or 3 allows cost-effective production of the ribbon cable.

Bei einer Vorrichtung nach Anspruch 4 sind elektrische Leiter 7, 7', 17 über ihre gesamte Breite elektrisch leitfähig. Außerdem ist die Breite des Leiters genau bestimmbar.In a device according to claim 4, electrical conductors 7, 7', 17 are electrically conductive over their entire width. In addition, the width of the conductor can be determined precisely.
Die Erfindung ist nach Anspruch 5 insbesondere für Flachbandkabel mit einer Vielzahl von nebeneinander verlaufenden Leitern geeignet.According to claim 5, the invention is particularly suitable for ribbon cables with a plurality of conductors running next to one another.
Eine Vorrichtung nach Anspruch 6 minimiert die Anzahl von verschiedenen Materialien im Kabel, indem kein zusätzlicher Klebstoff zur Verbindung der Trägerschicht, der Deckschicht und der elektrischen Leiter erforderlich ist.A device according to claim 6 minimizes the number of different materials in the cable by not requiring additional adhesive to connect the carrier layer, the cover layer and the electrical conductors.

Fig. 1 a) zeigt eine Trägerschicht 3 und eine diese überdeckend angeordnete Deckschicht 5. Zwischen den beiden Schichten 3, 5 sind Leiter 7, T und 17 angeordnet. Diese Leiter 7, 7\ 17 verlaufen im wesentlichen parallel zueinander und zur Längsrichtung der Trägerschicht 3 und der Deckschicht 5.Fig. 1 a) shows a carrier layer 3 and a covering layer 5 arranged to cover it. Conductors 7, 7 and 17 are arranged between the two layers 3, 5. These conductors 7, 7\ 17 run essentially parallel to one another and to the longitudinal direction of the carrier layer 3 and the covering layer 5.
Der Leiter 7 weist eine Basisschicht 9 aus einem elektrisch nicht leitenden Material auf. Im Ausführungsbeispiel ist Polyethylen vorgesehen. Die Basisschicht 9 ist beschichtet mit einer elektrisch leitfähigen Stromführungs-The conductor 7 has a base layer 9 made of an electrically non-conductive material.

Der elektrische Leiter T weist eine Basisschicht 9' aus einem elektrisch leitfähigen Kunststoff auf. Die Basisschicht 9' ist zusätzlich mit einer elektrisch leitenden Beschichtung, beispielsweise aus Aluminium, versehen.The electrical conductor T has a base layer 9' made of an electrically conductive plastic. The base layer 9' is additionally provided with an electrically conductive coating, for example made of aluminum.
Der Leiter 17 wird ausschließlich durch einen Streifen elektrisch leitfähigen Kunststoffes gebildet.The conductor 17 is formed exclusively by a strip of electrically conductive plastic.
Zur Herstellung der elektrischen Leiter 7, T, 17 werden diese als Streifen von einer größeren Folienbahn geschnitten. Sie besitzen dadurch eine definierte, gleichmäßige Breite. Außerdem ist eine ungleichmäßige Leitfähigkeit wegen eventueller ungleichmäßiger Beschichtung von Randbereichen ausgeschlossen. To produce the electrical conductors 7, T, 17, these are cut as strips from a larger film web. This gives them a defined, uniform width. In addition, uneven conductivity due to possible uneven coating of edge areas is excluded.
Gemäß Fig. 1 b) werden die Leiter 7, T, Xl gegeneinander beabstandet zwischen die Deckschicht 3 und die Trägerschicht 5 eingeschweißt. Sie werden dadurch jeweils an ihrem gesamten Umfang gegenüber den anderen Leitern und ihrer Umgebung elektrisch isoliert.According to Fig. 1 b), the conductors 7, T, Xl are welded at a distance from one another between the cover layer 3 and the carrier layer 5. They are thereby electrically insulated over their entire circumference from the other conductors and their surroundings.
Beim Leiter 7 erfolgt eine Leitung von Strom nur in der Stromführungsschicht 11. Solche Leiter sind z. B. für Signal-Leitungen geeignet.In conductor 7, current is only conducted in the current-carrying layer 11. Such conductors are suitable for signal lines, for example.
Beim Leiter T erfolgt eine Stromleitung in der Kunststoff-Folie 9' und in der Stromführungsschicht 11.In conductor T, current is conducted in the plastic film 9' and in the current-carrying layer 11.
Beim Leiter 17 erfolgt eine Stromleitung nur in der Kunststoff-Folie 18.In conductor 17, current is only conducted in the plastic film 18.
In einer vorteilhaften Ausführungsform ist das Material der Trägerschicht 3 und der Deckschicht 5 ein temperaturaktivierbarer Klebstoff. Wird er an seiner Oberfläche über eine bestimmte Aktivierungstemperatur erwärmt, wird er kle-In an advantageous embodiment, the material of the carrier layer 3 and the cover layer 5 is a temperature-activated adhesive. If its surface is heated above a certain activation temperature, it becomes adhesive.
