Description

Beschreibungdescription
Kombinierte elektrisch /optische FolienleitungenCombined electrical / optical foil cables
Die Er indung betrifft eine Anordnung von elektrischen Leitungen und optischen Wellenleitern insbesondere für den automobilen Einsatz.It relates to an arrangement of electrical lines and optical waveguides, in particular for automotive use.
Bei der Vernetzung von elektrischen und elektronischen Geräten in Kraftfahrzeugen ist häufig sowohl eine elektrische als auch eine optische Verbindung der Geräte erforderlich.The networking of electrical and electronic devices in motor vehicles often requires both an electrical and an optical connection of the devices.
Vorwiegend werden konventionelle elektrische Kabel und konventionelle Lichtleitfasern ( z.B. Polymeroptische Faser mit 1 mm Kerndurchmesser) zur Vernetzung in Kfzs ein- gesetzt. Für bestimmte Bauräume werden bereits sogenannte elektrische Folienleitungssätze eingesetzt. In eine flexible Polymerfolie sind beispielsweise elektrische Leitungen einlaminiert. Außerdem gibt es bereits sogenannte Faserbändchen, die aus einer parallelen Anordnung von Glasfasern bestehen, die ebenfalls zwischen zwei Polymerschichten eingebettet sind. Die Erfindung hat die Aufgabe eine Anordnung von elektrischen Leitungen und optischen Wellenleitern anzugeben, die ohne all zu große Schwierigkeiten in ein Fahrzeug installierbar ist, einen geringen Bauraum benötigt.Mainly conventional electrical cables and conventional optical fibers (eg polymer optical fiber with a core diameter of 1 mm) are used for networking in motor vehicles. So-called electrical foil cable sets are already used for certain installation spaces. For example, electrical lines are laminated into a flexible polymer film. There are also so-called fiber ribbons, which consist of a parallel arrangement of glass fibers, which are also embedded between two polymer layers. The invention has for its object to provide an arrangement of electrical lines and optical waveguides, which can be installed in a vehicle without too much difficulty, requires a small amount of space.
Die Erfindung ist in Patentanspruch 1 beschrieben. Vorteilhafte Ausgestaltungen und Weiterbildungen sind in den Unteransprüchen angegeben.The invention is described in claim 1. Advantageous refinements and developments are specified in the subclaims.
Die Erfindung hat den Vorteil, daß die elektrischen Leitungen und optischen Wellenleiter in einem Folienleitungssatz in das Fahrzeug installierbar sind. Die elektrischen Leitungen und optischen Wellenleiter sind dabei in flexible Polymerfolien eingebettet oder auf solchen appliziert. Das Einbetten hat den Vorteil, daß sie gegen äußere elektromagnetische und mechanische Störungen resistent sind. Das Applizieren erfolgt insbesondere durch Kleben, Verschrauben, Nieten, Verpressen oder Löten.The invention has the advantage that the electrical lines and optical waveguides can be installed in the vehicle in a film line set. The electrical lines and optical waveguides are embedded in or applied to flexible polymer films. Embedding has the advantage that they are resistant to external electromagnetic and mechanical interference. The application is carried out in particular by gluing, screwing, riveting, pressing or soldering.
Weiterhin ist vorteilhaft, daß passive und/oder aktive optische oder elektrische Komponenten in den Folienleitungssatz integrierbar sind. Vorzugsweise ist der Folienleitungssatz aus optischen Wellenleitern und elektrischen Leitungen auf oder in einer gemeinsamen Polymerfolie realisiert. Dabei werden die optischen Wellenleiter und elektrischen Leitungen durch passive und/oder aktive optische oder elektrische Komponenten zur Bildung von Folienschaltungen in oder auf der gemeinsamen Polymerfolie ergänzt. Hierdurch entsteht eine flexible und kompakte Anordnung zur Schaffung von optischen und/oder elektrischen Vernetzungen im Kraftfahrzeug.It is also advantageous that passive and / or active optical or electrical components can be integrated in the film line set. The set of film lines is preferably realized from optical waveguides and electrical lines on or in a common polymer film. The optical waveguides and electrical lines are supplemented by passive and / or active optical or electrical components for forming film circuits in or on the common polymer film. This creates a flexible and compact arrangement for creating optical and / or electrical networks in the motor vehicle.
Eine bevorzugte Ausbildung der Erfindung zeigt aktive optische Komponenten wieA preferred embodiment of the invention shows active optical components such as
Halbleiter-Sende-Empfangsdioden, die auf der Polymerfolie appliziert insbesondere mit dieser verklebt sind, und verschiedene elektrische Komponenten, die eine Treiberschaltung für die aktiven optischen Komponenten zur Ansteuerung und Energieversorgung der optischen Komponenten bilden und gemeinsam mit diesen eine Folienschaltung bilden. Dabei sind die elektrischen Komponenten der Treiberschaltung in räumlicher Nähe der aktiven optischen Komponenten angeordnet. Hierdurch sind sehr kompakte und funktionsfähige Anordnungen geschaffen, die sich besonders für den automobilen Einsatz eignen. Die Erfindung wird anhand von Ausführungsbeispielen beschrieben unter Bezugnahme auf schematische Zeichnungen.Semiconductor transmit / receive diodes, which are applied to the polymer film, in particular bonded to it, and various electrical components, which form a driver circuit for the active optical components for controlling and supplying energy to the optical components and together with these form a film circuit. The electrical components of the driver circuit are arranged in close proximity to the active optical components. This creates very compact and functional arrangements that are particularly suitable for automotive use. The invention is described using exemplary embodiments with reference to schematic drawings.

Es werden zwei Ausführungsformen für die Kombination elektrischer und optischer Leitungen in einem Folienleitungssatz angegeben.Two embodiments are given for the combination of electrical and optical lines in a film line set.
Gemäß Fig. 1 sind optische Wellenleiter 3, z.B. Mehrmodenfasern mit Glaskern oder planare Polymeriichtwellenleiter, mit den elektrischen Leitungen 2 in Polymerfolien 1 einlaminiert. Eine zusätzliche Folienschicht zwischen elektrischen und optischen Wellenleitern verbessert die mechanische Stabilität und Beständigkeit, ist nicht zwingend erforderlich.1, optical waveguides 3, e.g. Multimode fibers with glass core or planar polymer optical waveguide, laminated with the electrical lines 2 in polymer films 1. An additional film layer between electrical and optical waveguides improves the mechanical stability and durability, is not absolutely necessary.
Gemäß Fig. 2 ist auf der Oberfläche ein optischer Wellenleiter 3 aufgebracht. Der op- tische Wellenleiter ist z.B. eine Glasfasern oder ein planarer Polymeriichtwellenleiter. Die elektrische Leitung 2 ist in die Folie 1 eingebettet.2, an optical waveguide 3 is applied to the surface. The optical waveguide is e.g. a glass fiber or a planar polymer optical fiber. The electrical line 2 is embedded in the film 1.
Eine weitere Ausführungsform ergibt sich durch die Integration oder Applikation von passiven optischen Verzweigern oder passiven Auskoppelelementen (z.B. Spiegelele- mente, Gitterelemente, Prismen) , so daß optische Wellenleiternetze 4 gemeinsam mit elektrischen Netzen 5 im Folienleitungssatz integriert oder appliziert sind (siehe schematische Darstellung Figur 3) und damit Folienschaltungen hergestellt werden. Die Folien 1 , die die elektrischen und optischen Netzwerke enthalten, können direkt aufeinander aufgebracht werden.A further embodiment results from the integration or application of passive optical splitters or passive decoupling elements (for example mirror elements, grating elements, prisms), so that optical waveguide networks 4 are integrated or applied together with electrical networks 5 in the film line set (see schematic illustration in FIG. 3) ) and thus film circuits are produced. The Foils 1, which contain the electrical and optical networks, can be applied directly to one another.
Als weitere Ausführung werden neben passiven optischen Komponenten auch aktive optische Halbleiterkomponenten in den Folienleitungssatz integriert, so daß z.B. die auf dem Folienleitungssatz aufgebrachten optischen Sende-/Empfangselemente 6, 7 eine Folienschaltung bilden. Die optischen Sender und Empfänger werden derart auf dem Folienleitungssatz angeordnet, daß die optischen Sender-/Empfangselemente 6, 7 über die in der Folie 1 integrierten optischen Wellenleiter 8 miteinander innerhalb des Fo- liensatzes kommunizieren (Figur 4a).As a further embodiment, in addition to passive optical components, active optical semiconductor components are also integrated in the film line set, so that e.g. the optical transmission / reception elements 6, 7 applied to the film line set form a film circuit. The optical transmitters and receivers are arranged on the film line set in such a way that the optical transmitter / receiver elements 6, 7 communicate with one another within the film set via the optical waveguides 8 integrated in the film 1 (FIG. 4a).
In einem weiteren Ausführungsbeispiel kommunizieren die auf dem Folienleitungssatz aufgebrachten optischen Sende-/Empfangselement 6, 7, über z.B. eine Freistrahlstrecke außerhalb der Folienleitung (Figur 4b) und ermöglichen eine Kommunikation von der Folienschaltung nach außen. Eine in eine Folie 1 integrierte elektrische Leitung 9 kontaktiert die optischen Sende-/Empfangselemente 6, 7.In a further exemplary embodiment, the optical transmission / reception elements 6, 7 applied to the film line set communicate via e.g. a free jet path outside the film line (Figure 4b) and allow communication from the film circuit to the outside. An electrical line 9 integrated into a film 1 contacts the optical transmission / reception elements 6, 7.
Durch Aufbringen einer weiteren Polymerfolie als Schutzschicht auf die aktiven optischen Komponenten ist eine mechanisch stabile Folienschaltung herstellbar. A mechanically stable film circuit can be produced by applying a further polymer film as a protective layer on the active optical components.
