Abstract

The method involves bringing pairs of prefabricated conductors (1) in contact with the opposite sides of a carrier (8) of insulating material then sticking insulating films (9,10) to the carrier and conductors with through holes at least near one end of the cable separated from the end by a foil cross-strip and extending to continuous side strips on both edges of the foil approximately over their entire widths. AN Independent claim is also included for the following: a cable manufactured in accordance with the inventive method.

Description

Die Erfindung betrifft ein Verfahren zur Herstellung einer elektrischen Flachleiter-Bandleitung, mit welchem auf den beiden einander gegenüber liegenden Seiten eines bandförmigen Trägers aus Isoliermaterial flache elektrische Leiter mit im wesentlichen rechteckigem Querschnitt parallel und mit Abstand zueinander angeordnet werden und mit welchem auf den freien Seiten der Leiter jeweils eine für alle Leiter gemeinsame, abdeckende Folie aus Isoliermaterial angebracht wird (WO 01/62551 A1).The invention relates to a method for producing an electrical flat conductor ribbon cable, with which one on the two opposite sides ribbon-shaped carrier made of insulating material with flat electrical conductors essentially rectangular cross section can be arranged parallel and at a distance from each other and with which on the free sides of the ladder one common to all leaders, covering film made of insulating material is attached (WO 01/62551 A1).

Flachleiter-Bandleitungen- im folgenden kurz "FL-BL genannt - werden wegen ihrer flachen Bauweise mit Vorteil in der Verdrahtungstechnik eingesetzt. Sie dienen beispielsweise als Verbindungsleitungen für gedruckte Schaltungen, als Ersatz für Kabelbäume in elektrischen Geräten und in Personenkraftwagen und insbesondere wegen ihrer guten Biegbarkeit für Verdrahtungen im allgemeinen dort, wo wenig Platz vorhanden ist. Ein Vorteil der FL-BL liegt auch in der festen Einbettung der Leiter in der Isolierung, so daß sie kaum zu beschädigen sind, insbesondere nicht durch Knicken.Flat conductor ribbon cables - hereinafter referred to as "FL-BL" - are because of their flat design used with advantage in wiring technology. You serve for example as connecting lines for printed circuits, as a replacement for Wiring harnesses in electrical devices and in passenger cars and in particular because of their good flexibility for wiring in general where there is little space is available. Another advantage of the FL-BL is that the conductors are firmly embedded in the Insulation so that they can hardly be damaged, especially not by kinking.

Die Breite einer FL-BL hängt im wesentlichen von der Anzahl ihrer Leiter ab. Wenn mehr Leiter benötigt werden als eine maximal vorgegebene Breite der FL-BL zuläßt, dann muß dieselbe im Einsatzfall beispielsweise gefaltet werden oder es können zwei oder mehr getrennte FL-BL nebeneinander eingesetzt werden. Der Aufwand ist in beiden Fällen hoch und es ergeben sich Probleme beim Anschließen von Kontaktelementen an die Leiter. The width of an FL-BL essentially depends on the number of its conductors. If more Conductors are required as a maximum specified width of the FL-BL permits, then must they can be folded, for example, or two or more can be used separate FL-BL can be used next to each other. The effort is in both cases high and there are problems when connecting contact elements to the Ladder.

Aus der eingangs erwähnten WO 01/62551 A1 ist eine FL-BL bekannt, die bei relativ geringer Breite eine erhöhte Anzahl von Leitern hat. Es wird dazu eine beidseitig mit Leiterbahnen in Form von Metalldünnschichten bedruckte Leiterkarte eingesetzt. Die Leiterbahnen werden in bekannter Dünnschichttechnik beispielsweise durch Photolithograhie und Ätzen erzeugt. Sie sind entsprechend dünn und mechanisch empfindlich. Für einen größeren elektrisch leitenden Querschnitt müssen die Leiterbahnen verbreitert werden. Das führt zu einer entsprechenden Verbreiterung der FL-BL selbst oder zu einer verminderten Leiterzahl. Die Leiterbahnen sind in der fertigen FL-BL jeweils durch Isolierfolien abgedeckt. Zum Anschließen von Kontaktelementen an die dünnen Leiter sind an den Enden der FL-BL jeweils Verstärkungen angebracht, die aus mehreren Schichten bestehen. Die Leiter der FL-BL und an dieselben anzuschließende Kontaktelemente sind in Montageposition in den Verstärkungen eingeklemmt.A FL-BL is known from WO 01/62551 A1 mentioned at the beginning, which is relative narrow width has an increased number of conductors. There will be one on both sides Conductor tracks are used in the form of printed circuit boards made of metal thin layers. The Conductor tracks are made using known thin-film technology, for example Photolithography and etching generated. They are accordingly thin and mechanical sensitive. For a larger electrically conductive cross section, the Conductor tracks can be widened. This leads to a corresponding widening of the FL-BL itself or to a reduced number of conductors. The conductor tracks are in the finished FL-BL each covered by insulating foils. For connecting contact elements the thin conductors are attached to the ends of the FL-BL reinforcements that consist of several layers. The heads of the FL-BL and to the same Contact elements to be connected are in the assembly position in the reinforcements trapped.

Der Erfindung liegt die Aufgabe zugrunde, das eingangs geschilderte Verfahren so zu gestalten, daß eine FL-BL mit mechanisch stabilen Leitern herstellbar ist, an welche auf einfache Weise Kontaktelemente anschließbar sind.The invention is based on the object of the method described at the outset design that a FL-BL can be manufactured with mechanically stable conductors to which on contact elements can be connected in a simple manner.

Diese Aufgabe wird gemäß der Erfindung dadurch gelöst,

  • daß zunächst mindestens je zwei vorgefertigte Leiter zur Anlage an den einander gegenüber liegenden Seiten des Trägers aus Isoliermaterial gebracht werden und
  • daß anschließend abdeckende Folien aus Isoliermaterial mit dem Träger und mit den Leitern verklebt werden, die zumindest im Bereich eines Endes der FL-BL mit Durchbrechungen versehen sind, welche durch einen Querstreifen der Folien zum Ende der FL-BL beabstandet sind und welche sich bis auf durchgehende Seitenstreifen an beiden Rändern der Folien nahezu über ihre ganze Breite erstrecken.
According to the invention, this object is achieved by
  • that at least two prefabricated conductors are brought into contact with the mutually opposite sides of the carrier made of insulating material and
  • that subsequently covering foils of insulating material are glued to the carrier and to the conductors, which are provided with openings at least in the area of one end of the FL-BL, which are spaced apart by a transverse strip of the foils to the end of the FL-BL and which are apart continuous side stripes on both edges of the films extend almost over their entire width.

Bei diesem Verfahren werden in der Technik von FL-BL an sich übliche, vorgefertigte Leiter verwendet. Deren elektrisch leitender Querschnitt ist in weiten Grenzen frei wählbar, da die Leiter gegebenenfalls auch ausreichend dick sein können. Die Leiter sind dementsprechend mechanisch relativ unempfindlich. Trotzdem kann bei vorgegebener Breite einer FL-BL beispielsweise die doppelte Anzahl von Leitern eingesetzt werden. Es kann andererseits bei gleichbleibender Leiterzahl die Breite der FL-BL vermindert werden.In this process, the FL-BL technology uses standard, prefabricated ones Head used. Their electrically conductive cross section is free within wide limits selectable, since the conductors can also be sufficiently thick if necessary. The ladder are accordingly mechanically relatively insensitive. Still can predefined width of an FL-BL, for example, twice the number of conductors be used. On the other hand, the width of the FL-BL can be reduced.

Bei Einsatz dieses Verfahrens ist außerdem ein einfaches Kontaktieren der Leiter der FL-BL ohne zusätzliche Maßnahmen und Bauteile sichergestellt. Die Leiter liegen zumindest an einem Ende der FL-BL in den Durchbrechungen der abdeckenden Folien frei, so daß weiterführende Leiter beispielsweise direkt angelötet werden können. Trotz der Durchbrechungen bleiben die Leiter in ihrer Lage fixiert, da sie ebenso wie auf der ganzen Länge der FL-BL an ihren Enden durch den dort vorhandenen Querstreifen der Folien festgehalten werden.When using this method, it is also easy to contact the conductors of the FL-BL ensured without additional measures and components. At least the ladder lies free at one end of the FL-BL in the openings in the covering foils, so that further conductors can be soldered directly, for example. Despite the Openings keep the ladder fixed in their position, as they are on the the entire length of the FL-BL at its ends due to the horizontal stripe of the Slides are held.

    • In Fig. 1 ist das Ende einer FL-BL mit einer beliebigen Anzahl (mindestens zwei pro Seite) von Leitern 1 dargestellt. Die Leiter 1 haben einen im wesentlichen rechteckigen Querschnitt. Das bedeutet, daß sie ganz rechteckig sein können, aber auch abgerundete Seitenkanten haben können. Die Leiter 1 liegen in einer Durchbrechung 2 blank vor. Die Durchbrechung 2 ist an den Seiten der FL-BL von durchgehenden Seitenstreifen 3 und 4 und zum Ende der FL-BL durch einen Querstreifen 5 des abdeckenden Isoliermaterials begrenzt. In Fig. 1 is the end of an FL-BL with any number (at least two per side) represented by conductors 1. The conductors 1 have a substantially rectangular shape Cross-section. This means that they can be completely rectangular, but also rounded ones Can have side edges. The conductors 1 are bare in an opening 2. The Opening 2 is on the sides of the FL-BL of continuous side strips 3 and 4 and to the end of the FL-BL through a transverse strip 5 of the covering insulating material limited.

    An die Leiter 1 können Leiter 6 von weiterführenden Leitungen 7 direkt angeschlossen werden, beispielsweise durch Löten.Conductors 6 from further lines 7 can be connected directly to the conductors 1 by soldering, for example.

    Die Leiter 1 sind in der FL-BL in zwei Ebenen angeordnet. Sie sind durch einen aus Isoliermaterial bestehenden, bandförmigen Träger 8 voneinander getrennt. Auf den freien Seiten der Leiter 1 sind abdeckende Folien 9 und 10 angebracht, welche mit dem Träger 8 und den Leitern 1 verklebt sind. Die Durchbrechungen 2 sind bereits vor ihrer Aufbringung auf die Leiter 1 in den Folien 9 und 10 angebracht.The conductors 1 are arranged in two levels in the FL-BL. You are out by one Insulating material, band-shaped carrier 8 separated from each other. On the Free sides of the conductor 1 cover foils 9 and 10 are attached, which with the Carrier 8 and the conductors 1 are glued. The openings 2 are already in front of them Application to the conductor 1 in the films 9 and 10 attached.

    Die Leiter 1 können gemäß Fig. 3 fluchtend in der FL-BL angeordnet werden. Sie können gemäß Fig. 4 in den beiden Ebenen aber auch seitlich gegeneinander versetzt sein. Das kann bedeuten, daß die Leiter 1 der beiden unterschiedlichen Ebenen jeweils im Bereich der Lücken zwischen den Leitern 1 der anderen Ebene liegen. Es ist aber auch eine Überlappung zwischen den Leitern 1 der beiden unterschiedlichen Ebenen möglich. Das gilt besonders für den Fall, wenn unterschiedlich breite Leiter 1 in den beiden Ebenen verwendet werden.3, the conductors 1 can be arranged in alignment in the FL-BL. You can 4 in the two planes but also laterally offset from one another. The can mean that the head 1 of the two different levels each in the area the gaps between the conductors 1 of the other level. But it is also one Overlap between the conductors 1 of the two different levels possible. The applies particularly to the case when conductor 1 of different widths in the two levels be used.

    Zur Herstellung der FL-BL werden die bereits mit Durchbrechungen 2 versehenen Folien 9 und 10 von Spulen 11 und 12 abgezogen und einem Werkzeug 13 zugeführt, dem auch der Träger 8 mit den auf beiden Seiten anliegenden Leitern 1 zugeführt wird. Im Werkzeug 13 werden die Folien 9 und 10 mit dem Träger 8 und den Leitern 1 verklebt. Aus dem Werkzeug 13 tritt eine "endlose" FL-BL aus, so wie sie beispielsweise in Fig. 6 dargestellt ist.For the production of the FL-BL, the films already provided with openings 2 are used 9 and 10 deducted from coils 11 and 12 and fed to a tool 13, the the carrier 8 is also supplied with the conductors 1 resting on both sides. in the Tool 13, the foils 9 and 10 are glued to the carrier 8 and the conductors 1. An "endless" FL-BL emerges from the tool 13, as is the case, for example, in FIG. 6 is shown.

    In den Folien 9 und 10 der FL-BL sind in vorgegebenen Abständen Durchbrechungen 2 angebracht. Einzelne FL-BL können von dem endlosen Gebilde abgetrennt werden. Dazu wird dasselbe beispielsweise entlang der in Fig. 6 gestrichelt eingezeichneten Linie 14 getrennt. Die so abgetrennten FL-BL haben an ihren Enden die oben beschriebenen Durchbrechungen 2.Openings 2 are provided at predetermined intervals in the films 9 and 10 of the FL-BL appropriate. Individual FL-BL can be separated from the endless structure. To the same is done, for example, along the line 14 shown in broken lines in FIG. 6 Cut. The FL-BL thus separated have the ends described above at their ends Breakthroughs 2.
