Description

Die Erfindung betrifft ein dreidimensional (3D) geformtes Flachkabel und ein Verfahren zu seiner Herstellung.The invention relates to a three-dimensional (3D) shaped flat cable and a method for its production.

Aus dem Dokument DE-A 196 49 972 ist ein Verfahren zur Herstellung eines Leitungssatzes für Fahrzeuge bekannt, bei dem die Leitungen mit einer Trägerfolie verklebt und mit Steckern versehen werden und an einem formstabilen Träger befestigt sind, wobei wenigstens einige der Leitungen aus nicht isolierten Litzenleitern bestehen, die nacheinander und unabhängig voneinander auf eine isolierende, mit einer Klebeschicht versehene Trägerfolie entlang einer vorgegebenen Linienführung aufgelegt und anschließend entweder auf die Trägerfolie eine isolierende Schutzfolie aufgelegt und mit der Trägerfolie durch Druckanwendung verklebt oder die Trägerfolie und die aufgelegten Litzenleiter mit einer Schutzlackschicht überzogen und abschließend durch Beschneiden an die Kontur des Einsatzortes angepaßt wird. Nachteilig an diesem Verfahren ist die arbeitsaufwendige Verlegung der Leiterbahnen und deren Fixierung an dem formstabilen Träger.From the document DE-A 196 49 972 a method for producing a wiring harness for vehicles is known, in which the lines are glued to a carrier foil and provided with plugs and are fastened to a dimensionally stable carrier, wherein at least some of the lines consist of non-insulated stranded conductors which successively and independently to a insulating provided with an adhesive layer carrier film placed along a predetermined line and then either placed on the carrier film an insulating protective film and glued to the carrier film by applying pressure or coated the carrier film and the applied stranded conductor with a protective lacquer and finally adapted by trimming to the contour of the site becomes. A disadvantage of this method is the laborious laying of the tracks and their fixation on the dimensionally stable carrier.

Aus dem Dokument DE-A 196 28 850 sind ein Kabelbaum und ein Verfahren zu seiner Herstellung bekannt, der Stromkabel besitzt, die in einer ersten Harzschicht mit Vertiefungen angeordnet sind, wobei die erste Harzschicht so geformt ist, dass sie entlang einer vorbestimmten Verlegungsstrecke der Stromkabel verläuft und eine zweite Harzschicht, die fest mit der ersten Harzschicht verbunden ist, so dass sie zumindest die Vertiefung der ersten Harzschicht bedeckt und durch Vakuumformen angebracht ist.From the document DE-A 196 28 850 For example, a wiring harness and a method of manufacturing the same having power cables arranged in a first resinous layer having recesses, wherein the first resin layer is formed to extend along a predetermined routing distance of the power cables and a second resin layer fixed to the first resin layer is connected so as to cover at least the recess of the first resin layer and attached by vacuum molding.

Die bekannten Lösungen weisen den Nachteil auf, dass sie entweder in einem sehr arbeitsaufwendigen Prozess per Hand auf die Oberfläche des formstabilen Trägers aufgebracht werden müssen oder dass separate Teile hergestellt, die Leiter eingebracht und durch das zweite Harz in ihrer Lage fixiert werden müssen.The known solutions have the disadvantage that they either have to be applied by hand to the surface of the dimensionally stable support in a very labor-intensive process, or that separate parts have to be produced, the conductors introduced and fixed in position by the second resin.

Der Erfindung liegt die Aufgabe zugrunde, ein dreidimensional geformtes Flachkabel sowie ein Verfahren zu seiner Herstellung anzugeben, die die Nachteile der bekannten Lösungen vermeiden und die im Zwischenschritt die Herstellung von formstabilen Flachkabeln gestatten, die erst in einem zweiten Schritt an ihrem Einbauort plaziert werden.The invention has for its object to provide a three-dimensionally shaped flat cable and a method for its production, which avoid the disadvantages of the known solutions and allow the intermediate step, the production of dimensionally stable flat cables, which are placed only in a second step at their installation location.

Erfindungsgemäß wird die Aufgabe durch ein Flachkabel gelöst, bestehend aus einem Laminat, welches mindestens aus einer zwischen zwei Isolationsschichten eingebundenen Leiterbahn und mindestens einer Trägerschicht besteht, die mittels einer Klebeschicht miteinander verbunden sind und das auf ein positives Formwerkzeug aufgebracht und unter Anwendung von Wärme und Druck in Form gebracht sowie durch Abkühlung unter die Glastemperatur Tg der Klebeschicht oder Aushärtung der Klebeschicht in seiner dreidimensionalen Formgestalt fixiert ist, wobei als Klebeschicht ein thermoplastischer Kleber, eine thermoplastische Klebefolie und/oder ein Klebevliesstoff mit einem Schmelzpunkt Tm <180°C und/oder ein latent Reaktivkleber mit einer Vemetzungstemperatur <140°C eingesetzt wird. Klebeschichten dieser Art gestatten es, die Flachkabel- mit der porösen Trägerschicht fest zu verbinden und zu einem Zwischenformteil zu formen. Beim Einsatz von Reaktivklebern kann eine Abkühlung entbehrlich sein, allerdings muß eine entsprechende Verfestigung durch eine weitgehende Aushärtung durch Vernetzung eingetreten sein.According to the invention the object is achieved by a flat cable, consisting of a laminate which consists of at least one integrated between two insulating layers conductor track and at least one carrier layer which are interconnected by means of an adhesive layer and applied to a positive mold and using heat and pressure brought into shape and by cooling below the glass transition temperature T g of the adhesive layer or curing of Adhesive layer is fixed in its three-dimensional shape shape, being used as an adhesive layer, a thermoplastic adhesive, a thermoplastic adhesive film and / or an adhesive nonwoven fabric having a melting point T m <180 ° C and / or a latent reactive adhesive having a crosslinking temperature <140 ° C. Adhesive layers of this type make it possible to connect the flat cable and the porous support layer firmly and to form an intermediate molding. When reactive adhesives are used, cooling may be dispensable, but adequate solidification must have occurred through extensive curing by crosslinking.

Ein solches 3D-Flachkabel ist auch als Zwischenteil vor dem Einbau lagerfähig.Such a 3D flat cable is also storable as an intermediate part before installation.

Zur besseren Handhabung kann weiterhin eine der Abdeckung dienende weitere Vliesstoffschicht vorgesehen sein. Die poröse Trägerschicht besteht vorteilhafter Weise aus einem Vliesstoff oder Gewebe aus polymeren Fasern.For better handling, it is furthermore possible to provide a further nonwoven fabric layer serving for covering. The porous carrier layer is advantageously made of a nonwoven fabric or fabric of polymeric fibers.

Das erfindungsgemäße Flachkabel kann zumindest teilweise mit einem Thermoplast hinterspritzt sein. Damit ist die Herstellung an den Einbauort gestalteter Teile möglich.The flat cable according to the invention may be at least partially back-injected with a thermoplastic. This makes it possible to produce parts designed for the installation site.

Vorteilhafter Weise sind die Leiter der Leiterbahn vor der Laminierung zumindest in Teilbereichen ihrer Oberfläche zur Bildung von Kontaktfeldern freigelegt.Advantageously, the conductors of the conductor track are exposed before the lamination at least in partial areas of their surface to form contact fields.

Besonders bevorzugt ist ein Flachkabel, das mit elektronischen Bauelementen bestückt ist. Dadurch können in sehr rationeller Weise funktionstechnisch fertige elektronische Einbauteile hergestellt werden.Particularly preferred is a flat cable that is equipped with electronic components. As a result, functionally finished electronic components can be produced in a very rational manner.

Die Herstellung der 3D-Flachkabel als Zwischenteile erfolgt in der Weise, dass das aus Flachkabel-, Klebe- und Vliesstoffschichten bestehende Laminat auf ein positives Formwerkzeug aufgebracht, ausgerichtet und unter Anwendung von Wärme und/oder Strahlung und/oder Druck in Form gebracht sowie durch Abkühlung unter die Glastemperatur Tg der Klebeschicht oder Aushärtung der Klebeschicht in seiner Formgestalt fixiert wird. Als Druck wird beispielsweise ein Unterdruck an der Rückseite des Laminats angelegt.The production of the 3D flat cables as intermediate parts takes place in such a way that the laminate consisting of flat cable, adhesive and nonwoven layers is applied to a positive molding tool, aligned and shaped using heat and / or radiation and / or pressure and through Cooling below the glass transition temperature T g of the adhesive layer or curing of the adhesive layer is fixed in its shape. As pressure, for example, a negative pressure is applied to the back of the laminate.

Vorzugsweise werden die in ihrer Formgestalt fixierten Laminatteile durch Stanzen, Fräsen oder Schneiden nachbearbeitet und in einem separaten Schritt an ihrem Einsatzort eingebaut oder zur besseren Montage zumindest teilweise in einem Spritzgußverfahren mit einem Thermoplast hinterspritzt.Preferably, the fixed in shape in their shape laminate parts are reworked by punching, milling or cutting and installed in a separate step at their site or back-injected for better assembly at least partially in an injection molding process with a thermoplastic.

Zur Temperaturvergleichmäßigung wird vorzugsweise eine Metallfolie beim Laminierungsprozeß und/oder im Formwerkzeug eingesetzt.For temperature uniformity, a metal foil is preferably used in the lamination process and / or in the mold.

Als Vliesstoff für das genannte Verfahren werden vorzugsweise solche aus Polyester oder Polyamid eingesetzt, die eine Dicke von 0,1 bis 2 mm, eine Reißfestigkeit von 50 bis 250 N/50mm und eine Dehnung von 30 bis 50% besitzen. Das als thermoplastische Klebeschicht eingesetzte Klebevlies sollte eine Erweichungstemperatur zwischen 30 und 180°C besitzen, sein Flächengewicht sollte zwischen 10 und 70 g/m2 liegen und es sollte einen niedrigen Schmelzindex aufweisen.As the nonwoven fabric for the said process, it is preferable to use those of polyester or polyamide having a thickness of 0.1 to 2 mm, a tensile strength of 50 to 250 N / 50 mm and an elongation of 30 to 50%. The adhesive nonwoven used as a thermoplastic adhesive layer should have a softening temperature between 30 and 180 ° C, its basis weight should be between 10 and 70 g / m 2 and it should have a low melt index.
