Abstract

Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung eines Kabels mit den Schritten: Bereitstellen eines Flachleitung aus einem ersten Metallwerkstoff, Beschichten der bereitgestellten Flachleitung mit einem zweiten, von dem ersten Metallwerkstoff verschiedenen Metallwerkstoff und Aufbringen einer Isolationsschicht auf die Flachleitung samt Beschichtung.The present invention relates to a method for producing a cable, comprising the steps of: providing a flat cable made of a first metal material, coating the flat cable provided with a second metal material different from the first metal material and applying an insulation layer to the flat cable including the coating.

Description

Der Gegenstand betrifft ein Verfahren zur Herstellung eines Kabels sowie ein Kabel, insbesondere für automotive Anwendungen.The subject relates to a method for producing a cable and a cable, in particular for automotive applications.

Die Automobilindustrie nutzt statt Rundleitungen immer häufiger profilierte, massive Flachleitungen. Flachleitungen haben dabei insbesondere einen rechteckigen Querschnitt. Aufgrund ihres vorteilhaften Verhältnisses zwischen Gewicht und Oberfläche sind Flachleitungen insbesondere für Batterieleitungen für Starter-Generator-Leitungen im Einsatz. Auf den Flachleitungen fließen hohe Ströme, so dass die Flachleitungen große Leitungsquerschnitte aufweisen. Darüber hinaus haben Flachleitungen den Vorteil, dass sie in engen, unzugänglichen Bereichen große Leitungsquerschnitte realisieren können und gleichzeitig eine hohe Stromtragfähigkeit für Batterieleitungen ermöglichen.The automotive industry is increasingly using profiled, massive flat cables instead of round cables. Flat cables in particular have a rectangular cross section. Because of their advantageous ratio between weight and surface area, flat cables are used in particular for battery cables for starter-generator cables. High currents flow on the flat cables, so that the flat cables have large cable cross sections. In addition, flat cables have the advantage that they can realize large cable cross sections in narrow, inaccessible areas and at the same time enable a high current carrying capacity for battery cables.

Im Zuge der zunehmenden Elektrifizierung verschiedenartigster Verbraucher in einem Kraftfahrzeug sind Abgänge entlang eines Batteriestrangs an verschiedenen Punkten innerhalb des Fahrzeugs notwendig. Die Flachleitung wird über Verbindungsleitungen mit der Fahrzeugperipherie, beispielsweise Stromverteilern, Fremdstartstützpunkten, Komfortverbrauchern und dergleichen verbunden. Die Verbindungsleitungen können dabei sowohl Rundleitungen als auch erneut Flachleitungen sein. Die Verbindungsleitungen müssen mit der zentralen Batterieleitung verbunden werden. Dies erfolgt bisher meist über Anschlussbolzen, z.B. Gewindebolzen, mit standardisierter Anschlussgeometrie.In the course of the increasing electrification of a wide variety of consumers in a motor vehicle, outgoings along a battery string at various points within the vehicle are necessary. The flat cable is connected via connecting lines to the vehicle periphery, for example power distributors, jump starting points, comfort consumers and the like. The connecting cables can be both round cables and again flat cables. The connecting cables must be connected to the central battery cable. So far, this has mostly been done using connecting bolts, e.g. Threaded bolt, with standardized connection geometry.

Das Aufbringen von Anschlussbolzen auf Flachleitungen ist jedoch in zweierlei Hinsicht nachteilig. Einerseits benötigen die Anschlussbolzen einen ausreichenden Bauraum und erschweren das Verlegen der Leitung bei der Montage, andererseits müssen die Anschlussbolzen beispielsweise mittels Rotationsreibschweißen an die Flachleitung angeschweißt werden und müssen daher rotationssymmetrisch sein. Dies ist nicht immer möglich, insbesondere in komplizierten Verlegegeometrien.The application of connection bolts to flat cables is disadvantageous in two respects. On the one hand, the connection bolts require sufficient installation space and make it difficult to lay the line during assembly, on the other hand, the connection bolts must be attached to the, for example, by means of rotary friction welding Flat cables are welded on and must therefore be rotationally symmetrical. This is not always possible, especially in the case of complicated installation geometries.

Es wäre von Vorteil, wenn auf die Flachleitung unmittelbar eine Verbindung aufgeschraubt werden könnte, dies ist jedoch insbesondere bei der Verwendung von unedlen Metallwerkstoffen für die Flachleitung, beispielsweise Aluminiumwerkstoffen, nachteilig. Einerseits ist Aluminium duktil, so dass es zum Fließen entlang der Verschraubung kommen kann, andererseits neigt das unedlere Metall zu Kontaktkorrosion.It would be advantageous if a connection could be screwed directly onto the flat cable, but this is disadvantageous in particular when using base metal materials for the flat cable, for example aluminum materials. On the one hand, aluminum is ductile, so that it can flow along the screw connection, on the other hand, the less noble metal tends to contact corrosion.

Aus diesem Grunde lag dem Gegenstand die Aufgabe zugrunde, eine Flachleitung zur Verfügung zu stellen, welche sich zur unmittelbaren Kontaktierung mit Abgängen eignet.For this reason, the object of the object was to provide a flat cable which is suitable for direct contact with outlets.

Diese Aufgabe wird gegenständlich durch ein Verfahren nach Anspruch 1 gelöst. Hierbei wird ein Kabel in einem kontinuierlichen Prozess hergestellt. Dazu wird zunächst eine Flachleitung aus einem ersten Metall bereitgestellt. Insbesondere kann eine Flachleitung von einem Extruder oder einem Coil als nahezu Endlosmaterial zur Verfügung gestellt werden.This object is achieved objectively by a method according to claim 1. Here, a cable is manufactured in a continuous process. For this purpose, a flat cable made of a first metal is first provided. In particular, a flat cable from an extruder or a coil can be made available as almost endless material.

Die Flachleitung wird dabei bevorzugt mit einem konstanten Vortrieb bereitgestellt und während des Vortriebs unmittelbar beschichtet. Die Beschichtung erfolgt dabei mit einem zweiten, von dem ersten Metall verschiedenen Metall. Die Beschichtung erfolgt dabei bevorzugt partiell oder auch vollflächig auf der Flachleitung, insbesondere durch Reibung unter Druck.The flat cable is preferably provided with constant jacking and coated directly during the jacking. The coating is done with a second metal different from the first metal. The coating is preferably carried out partially or even over the entire surface of the flat cable, in particular by friction under pressure.

Mit dem gleichen Vortrieb wird die so zunächst beschichtete Flachleitung mit einer Isolationsschicht beschichtet. Somit ist es möglich, mit einem konstanten Vorschub auf den beschichteten Flachleiter in einem Extrusionsprozess die Isolationsschicht aufzubringen.The flat cable that was initially coated in this way is coated with an insulation layer with the same drive. It is thus possible to apply the insulation layer in an extrusion process with a constant feed rate on the coated flat conductor.

Bei dem gegenständlichen Verfahren erfolgt das Bereitstellen, Beschichten und Aufbringen in einem kontinuierlichen Prozess, bei dem die Flachleitung mit einer gleichen Vorschubgeschwindigkeit in einem Stück bereitgestellt wird und der Beschichtung und dem Aufbringen zugeführt wird.In the case of the method in question, the preparation, coating and application are carried out in a continuous process in which the flat cable is provided in one piece at the same feed rate and is supplied to the coating and application.

Gemäß einem Ausführungsbeispiel wird vorgeschlagen, dass die Schritte Bereitstellen, Beschichten und Aufbringen unmittelbar aufeinander folgen. Hierdurch ist es möglich, in einer kompakten Anlage ein komplett vorkonfektioniertes Kabel zur Verfügung zu stellen, welches sich zum unmittelbaren Verschrauben mit Anschlussbolzen eignet.According to one exemplary embodiment, it is proposed that the steps of providing, coating and applying follow one another directly. This makes it possible to provide a completely pre-assembled cable in a compact system, which is suitable for direct screwing with connection bolts.

Das bereitgestellte Kabel ist bevorzugt zunächst von einem Coil abgecoilt. Dadurch ist es möglich, den kontinuierlichen Prozess an einem nahezu Endlosmaterial durchzuführen, da auf einem Coil mehrere 100 Meter Kabel bereitgestellt werden können, die in dem kontinuierlichen Prozess vollständig beschichtet und isoliert werden können.The cable provided is preferably initially coiled from a coil. This makes it possible to carry out the continuous process on an almost endless material, since several 100 meters of cable can be provided on a coil, which can be completely coated and insulated in the continuous process.

Gemäß einem Ausführungsbeispiel wird vorgeschlagen, dass das Beschichten mittels mechanischer Beschichtungsverfahren, insbesondere Walzplattieren, Reibbeschichten oder Pulverbeschichten erfolgt. Durch das Entfallen einer Galvanik ist der Beschichtungsprozess besonders umweltschonend.According to one exemplary embodiment, it is proposed that the coating be carried out by means of mechanical coating methods, in particular roll cladding, friction coating or powder coating. By eliminating electroplating, the coating process is particularly environmentally friendly.

Wie bereits erwähnt, wird bevorzugt, wenn das Aufbringen mittels Extrudieren erfolgt.As already mentioned, it is preferred if the application is carried out by extrusion.

Da in der Regel die Kontaktierung mit einem Abgang nur auf einer Oberfläche des Flachteils erfolgt, wird vorgeschlagen, dass die Beschichtung auf nur einer breiten Oberfläche des Flachteils erfolgt. Somit wird weniger Beschichtungsmaterial verwendet und insbesondere kann das mechanische Beschichtungsverfahren auf nur auf eine Oberfläche des Flachteils beschränkt werden.Since contact is usually made with an outlet only on one surface of the flat part, it is proposed that the coating be carried out on only one broad surface of the flat part. Thus less coating material is used and in particular the mechanical coating process can be limited to only one surface of the flat part.

Gemäß einem Ausführungsbeispiel wird vorgeschlagen, dass die Beschichtung abschnittsweise auf das Flachteil aufgebracht wird, wobei zwischen zwei Abschnitten mit einer Beschichtung ein Abschnitt ohne eine Beschichtung liegt. Hierdurch kann kostengünstig eine individuelle Beschichtung auf die Flachleitung aufgebracht werden. Je nach Anwendung des Kabels kann die Beschichtung in den jeweils hierfür notwendigen Bereichen erfolgen.According to one exemplary embodiment, it is proposed that the coating be applied in sections to the flat part, a section without a coating lying between two sections with a coating. As a result, an individual coating can be applied to the flat cable at low cost. Depending on the application of the cable, the coating can be carried out in the areas required for this.

Gemäß einem Ausführungsbeispiel wird vorgeschlagen, dass der erste Metallwerkstoff ein Kupferwerkstoff ist und dass der zweite Metallwerkstoff ein Aluminiumwerkstoff ist oder dass der erste Metallwerkstoff ein Aluminiumwerkstoff ist und dass der zweite Metallwerkstoff ein Kupferwerkstoff ist. Die Wahl des zweiten Metallwerkstoffs erfolgt in der Regel entsprechend der Anbindung des Kabels an ein Anschlussteil. Je nach Art und Material des Anschlussteils, insbesondere des zu verschraubenden Bolzens, wird das Metallwerkstoff der Beschichtung gewählt. Hier wird insbesondere ein Metallwerkstoff gewählt, welcher sicherstellt, dass möglichst sortenreine oder ähnliche Metalle an der Verbindung zwischen Kabel und Anschlussteil unmittelbar aneinander anliegen.According to an exemplary embodiment, it is proposed that the first metal material is a copper material and that the second metal material is an aluminum material or that the first metal material is an aluminum material and that the second metal material is a copper material. The second metal material is usually selected according to the connection of the cable to a connector. The metal material of the coating is selected depending on the type and material of the connecting part, in particular the bolt to be screwed. In particular, a metal material is selected here, which ensures that as pure or similar metals as possible are in direct contact with one another at the connection between the cable and the connecting part.

Die Flachleitung wird gemäß einem Ausführungsbeispiel als Endlosband zugeführt, insbesondere wird die Flachleitung von einem Coil abgewickelt.According to one embodiment, the flat cable is fed as an endless belt, in particular the flat cable is unwound from a coil.

Wie bereits erläutert, wird das gegenständliche Kabel als Energieleitung in automotiven Anwendungen eingesetzt. Aus diesem Grunde wird vorgeschlagen, dass die Flachleitung aus einem Vollmaterial gebildet ist, um eine besonders gute Stromtragfähigkeit zu gewährleisten. Darüber hinaus ist ein Kabelquerschnitt von zumindest 15 mm2, bevorzugt zwischen 15 mm2 und 250 mm2 sinnvoll für die gegenständliche Anwendung.As already explained, the cable in question is used as a power line in automotive applications. For this reason, it is proposed that the flat cable be formed from a solid material in order to ensure a particularly good current carrying capacity. In addition, a cable cross section of at least 15 mm 2 , preferably between 15 mm 2 and 250 mm 2 is useful for the application in question.

Ein weiterer Aspekt ist eine Vorrichtung zur Durchführung des Verfahrens nach Anspruch 11.Another aspect is an apparatus for performing the method according to claim 11.

Nachfolgend wird der Gegenstand anhand einer Ausführungsbeispiele zeigenden Zeichnung näher erläutert. In der Zeichnung zeigen:

Fig. 1 zeigt eine Zuführeinrichtung 2, beispielsweise ein Coil, von der eine Flachleitung 4 abgewickelt wird. Die Flachleitung 4 wird entlang einer Vorschubrichtung 6 kontinuierlich mit einem bevorzugt konstanten Vorschub einer Beschichtungseinheit 8 zugeführt. Die Beschichtungseinheit 8 kann beispielsweise eine Einrichtung zur Walzplattierung oder zum Reibschweißen sein, mit der ein Beschichtungswerkstoff auf die Flachleitung aufgebracht wird. Die Beschichtungseinheit 8 bringt als Beschichtungswerkstoff z.B. ein dünnes Metallblech oder eine Metallfolie 10 auf die Flachleitung 4 in einem kontinuierlichen Prozess auf. Dabei kann der Vorschub der Flachleitung 4 entlang der Beschichtungseinheit 8 konstant sein. Der Beschichtungswerkstoff kann durch die Beschichtungseinheit 8 auf zumindest eine Oberfläche, bevorzugt eine breite Seite der Flachleitung 4, aber auch auf mehr als eine Oberfläche der Flachleitung 4 aufgebracht werden. Fig. 1 shows a feed device 2, for example a coil, from which a flat cable 4 is unwound. The flat cable 4 is fed continuously to a coating unit 8 along a feed direction 6 with a preferably constant feed. The coating unit 8 can be, for example, a device for roll cladding or for friction welding, with which a coating material is applied to the flat cable. The coating unit 8 applies, for example, a thin metal sheet or a metal foil 10 to the flat line 4 as a coating material in a continuous process. The feed of the flat cable 4 along the coating unit 8 can be constant. The coating material can be applied by the coating unit 8 to at least one surface, preferably a wide side of the flat cable 4, but also to more than one surface of the flat cable 4.

Der Beschichtungswerkstoff kann ununterbrochen auf die Flachleitung 4 aufgebracht werden oder mit Unterbrechungen. Dabei können Bereiche mit einer Beschichtung 10 auf Bereiche ohne Beschichtung 10 folgen. Zwischen zwei Bereichen mit einer Beschichtung 10 kann ein Bereich ohne eine Beschichtung 10 liegen. Die Abstände zwischen den Bereich mit Beschichtung 10 kann dabei frei einstellbar sein. Auch können die Abstände zwischen zwei Bereichen mit Beschichtung 10 voneinander verschieden sein.The coating material can be applied to the flat cable 4 continuously or with interruptions. Areas with a coating 10 can follow areas without a coating 10. An area without a coating 10 can lie between two areas with a coating 10. The distances between the areas with coating 10 can be freely adjustable. The distances between two areas with coating 10 can also be different from one another.

Das Material der Flachleitung 4 unterscheidet sich von dem Material der Beschichtung 10. Die Flachleitung kann beispielsweise aus einem Aluminiumwerkstoff sein und die Beschichtung 10 aus einem Kupferwerkstoff.The material of the flat cable 4 differs from the material of the coating 10. The flat cable can be made of an aluminum material, for example, and the coating 10 can be made of a copper material.

Die beschichtete Flachleitung 4 wird einer Isolationseinrichtung 12 zugeführt. Die Isolationseinrichtung 12 kann beispielsweise ein Extruder sein. In der Isolationseinrichtung 12 wird ein isolierendes Material 14 auf die beschichtete Flachleitung 4 aufgebracht und die beschichtete Flachleitung 4 wird umfänglich mit dem Isolator 14 beschichtet.The coated flat cable 4 is fed to an insulation device 12. The insulation device 12 can be an extruder, for example. In the insulation device 12, an insulating material 14 is applied to the coated flat line 4 and the coated flat line 4 is coated with the insulator 14 over the circumference.

Das nun erhaltene Kabel 16 weist als Seele eine Flachleitung 4 mit einer Beschichtung 10 auf und ist vollumfänglich mit dem Isolator 14 ummantelt. Das Kabel 16 wird anschließend beispielsweise vorkonfektioniert, indem es geschnitten wird oder erneut auf ein Coil aufgewickelt.The cable 16 now obtained has a flat cable 4 with a coating 10 as a core and is fully encased with the insulator 14. The cable 16 is then pre-assembled, for example, by cutting it or winding it again on a coil.

Fig. 2 zeigt ein stirnseitig abisoliertes Kabel 16. Zu erkennen ist, dass der Isolator 14 stirnseitig abisoliert ist. Ferner ist zu erkennen, dass auf die Flachleitung 4 eine Beschichtung 10 aufgebracht ist. Die Beschichtung 10 ist entlang der gesamten breiten Oberfläche der Flachleitung 4 aufgebracht. Fig. 2 shows a cable 16 stripped at the end. It can be seen that the insulator 14 is stripped at the end. It can also be seen that a coating 10 is applied to the flat cable 4. The coating 10 is applied along the entire broad surface of the flat cable 4.

Eine teilweise Beschichtung bzw. abschnittsweise Beschichtung ist ebenfalls möglich, wie in der Fig. 3 gezeigt.A partial coating or coating in sections is also possible, as in the Fig. 3 shown.

Die Fig. 3 zeigt die Flachleitung 4 mit Beschichtungen 10 die abschnittsweise aufgebracht wurden. Die Abstände zwischen den Bereichen mit Beschichtung 10 und den Bereichen ohne Beschichtung 10 können variabel sein. Auch kann die Breite der Abschnitte mit Beschichtung 10 variabel sein. Der so abschnittsweise beschichtete Flachleiter 4 wird in der Isolationseinrichtung 12 mit dem Isolator 14 beschichtet. Bei der anschließenden Konfektionierung kann das Kabel 16 dann so abgelängt werden, dass die Beschichtung 10 in den Bereichen vorhanden ist, in denen Abgänge auf das Kabel 16 aufgebracht werden. Dies können beispielsweise Bolzen sein, die in die Beschichtung 10 eingeschraubt werden.The Fig. 3 shows the flat cable 4 with coatings 10 which were applied in sections. The distances between the areas with coating 10 and the areas without coating 10 can be variable. The width of the sections with coating 10 can also be variable. The flat conductor 4 coated in this way in sections is coated with the insulator 14 in the insulation device 12. In the subsequent assembly, the cable 16 can then be cut to length so that the coating 10 is present in the areas in which outlets on the Cable 16 are applied. These can be bolts, for example, which are screwed into the coating 10.

Durch eine geeignete Wahl des Werkstoffs der Beschichtung 10 kann beispielsweise eine sortenreine Verschraubung mit einem Bolzen gewährleistet werden. Der intermetallische Übergang zwischen der Beschichtung 10 und der Flachleitung 4 bleibt dabei durch die Isolation 14 vollumfänglich geschützt, so dass keine Umgebungsfeuchte in den metallischen Übergang eindringen kann, was Kontaktkorrosion erschwert.A suitable choice of the material of the coating 10 can ensure, for example, a type-specific screw connection with a bolt. The intermetallic transition between the coating 10 and the flat cable 4 remains fully protected by the insulation 14, so that no ambient moisture can penetrate into the metallic transition, which makes contact corrosion more difficult.
