Description

Die Erfindung betrifft das Isolieren der elektrischen Verbindungen mehrerer Flachleiterkabel, unabhängig von ihrem Aufbau bzw. ihrer Herstellung: Laminiert, extrudiert, versiegelt oder auch auf andere Weise hergestellt.The invention relates to the insulation of the electrical connections of several flat conductor cables, regardless of their structure or manufacture: laminated, extruded, sealed or made in another way.

Aus verschiedenen Gründen, hauptsächlich wegen ihrer automatisierten Handhabbarkeit, werden in der Industrie, insbesondere im Automobilbau, zunehmend Flachleiterkabel, sogenannte FFC's, verwendet. Die vorliegende Erfindung betrifft die FFC's, bei denen einzelne, parallel zueinander und in einer gemeinsamen Ebene geführte Leiterbahnen durch isolierendes Material voneinander und nach außen elektrisch isoliert sind. Beispielsweise werden extrudierte FFC so hergestellt, dass einzelne Leiterbahnen in speziellen Spritzgußanlagen von einem elektrisch isolierenden Extrudat umhüllt werden, das die einzelnen Leiterbahnen gegeneinander und gegenüber der Umgebung elektrisch isoliert und mechanisch hält.For various reasons, mainly because of their automated handling, Flat industry cables, so-called FFC's used. The present invention relates to the FFC's in which individual, Conductor tracks run parallel to one another and in a common plane insulating material from each other and electrically isolated from the outside. For example extruded FFC are manufactured in such a way that individual conductor tracks in special injection molding systems be encased by an electrically insulating extrudate that the individual Conductors electrically isolated from each other and from the environment and mechanically holds.

Zur Bildung von sogenannten Kabelbäumen werden die Leiter der einzelnen FFC's nach dem Entfernen der Isolierschichte direkt, d.h. ohne Zwischenkabel oder Stecker, miteinander verlötet, verschweißt, gecrimpt, geklebt, oder auf andere elektrisch leitende Weise miteinander verbunden, gegebenenfalls in mehreren Schichten, somit unter Einbeziehen von mehr als zwei FFC's. Die Verbindungsstelle wird schließlich durch Isoliergut, nämlich durch Umwickeln mit einer elektrisch isolierenden Folie, die selbstklebend sein kann, oder nach dem Aufbringen von Klebstoff aufgewickelt wird, wiederum isoliert. Derartige Verbindungsstellen nennt man wegen der rasterförmigen Anordnung der einzelnen Verbindungen in Draufsicht allgemein "Matrizen".To form so-called cable harnesses, the conductors of the individual FFC's are removal of the insulating layer directly, i.e. without intermediate cable or plug, with each other soldered, welded, crimped, glued, or in another electrically conductive manner connected, possibly in several layers, thus including more than two FFC's. The connection point is finally insulated, namely by wrapping with an electrically insulating film, which can be self-adhesive, or after the application of adhesive is wound up, again insulated. Such junctions is called because of the grid-like arrangement of the individual connections generally "matrices" in plan view.

Zusätzlich zu der elektrischen Isolierung als Hauptfunktion soll das Isoliergut weitere Anforderungen wie zum Beispiel das Aufnehmen von mechanischen Belastungen (Zug, Torsion, Schälen, Vibration), das Abdichten gegen Wasser, die Hydrolysebeständigkeit, die Schwerentflammbarkeit erfüllen und eine gute Verarbeitbarkeit ermöglichen, all dies bei möglichst niedrigen Kosten und möglichst automatisierbarer Aufbringung. Von besonderer Bedeutung sind auch die Eigenschaften hinsichtlich der Recycelbarkeit des Isoliergutes. In addition to the electrical insulation as the main function, the insulation material should meet further requirements such as the absorption of mechanical loads (tension, torsion, Peeling, vibration), sealing against water, resistance to hydrolysis, the Flame retardancy and good processability, all this the lowest possible costs and the most automatable application possible. Of special The properties with regard to the recyclability of the insulation material are also important.

In nahezu allen genannten Belangen sind die im Stand der Technik verwendeten Folien weit weg vom angestrebten Ziel: Ihre Handhabung ist kompliziert und nicht zu automatisieren, die Übertragung mechanischer Belastungen ist schlecht, die Dichtheit ist unbefriedigend und die Recyclingeigenschaften sind völlig ungenügend.The films used in the prior art are used in almost all of the matters mentioned far from the desired goal: their handling is complicated and cannot be automated, the transmission of mechanical loads is bad, the tightness is unsatisfactory and the recycling properties are completely insufficient.

Es besteht somit ein großer Bedarf an einer besseren Isolierung für die eingangs genannten Matrizen und es ist das Ziel der Erfindung, solche Matrizen zu schaffen, die insbesondere automatisch hergestellt werden können, bei denen das Isoliergut gleichermaßen wie die FFC zu recyclen sind, die mechanischen Beanspruchungen gut übertragen und ertragen und bei denen die Dichtheit zuverlässig gegeben ist.There is therefore a great need for better insulation for the aforementioned Matrices and it is the object of the invention to provide such matrices which in particular can be automatically produced in which the insulating material is the same as that FFCs are to be recycled, the mechanical loads are well transmitted and endured and where the tightness is reliable.

Erfindungsgemäß werden diese Ziele dadurch erreicht, dass die Matrizen mit einem ähnlichen, bevorzugt dem gleichen Material wie das Isoliergut isoliert werden, das als Isolationsmaterial bei ihrer Herstellung im Zuge der Extrusion eingesetzt wurde. Dieses Material wird "Versiegelungswerkstoff" genannt.According to the invention, these goals are achieved in that the matrices with a similar, preferably the same material as the insulation, which is used as insulation material was used in their manufacture in the course of extrusion. This material is called "sealing material".

In einer ersten Variante der Erfindung wird der Versiegelungswerkstoff in aufgeschmolzener Form flüssig bzw. dickflüssig innerhalb einer Form um die Matrix gebracht und durch anschließende Temperatur- und Druckeinwirkung in der Form mit dem Isolierwerkstoff der FFC's verbunden und ausgehärtet. Das Isolierwerkzeug weist dabei bevorzugt zwei Stempelflächen auf, deren Form der jeweils zu isolierenden Matrix angepaßt ist.In a first variant of the invention, the sealing material is melted Form liquid or viscous in a mold brought around the matrix and through subsequent exposure to temperature and pressure in the mold with the insulating material the FFC's connected and cured. The insulating tool preferably has two Stamp surfaces whose shape is adapted to the respective matrix to be isolated.

Bei einer anderen Variante der Erfindung wird der Versiegelungswerkstoff in Folienform gebracht, in einem, bevorzugt aber in zwei Teilen um die Matrix gelegt und miteinander und mit dem Isolierwerkstoff im Bereich der Matrix durch Temperatur- und Druckeinwirkung flächig verschweißt.In another variant of the invention, the sealing material is in the form of a film brought, in one, but preferably in two parts placed around the matrix and together and with the insulating material in the area of the matrix by the action of temperature and pressure welded flat.

Ein besonderer Vorteil beider Varianten besteht darin, dass der Versiegelungswerkstoff und der Isolierwerkstoff der FFC in ihren Eigenschaften gleich oder zumindest so ähnlich sind, dass sie sich nicht nur bestmöglich, sondern ohne Hilfe eines Klebstoffes, Haftvermittlers, od.dergl. verbinden. A particular advantage of both variants is that the sealing material and the insulating material of the FFC has the same or at least similar properties are that they not only do their best, but without the help of an adhesive, adhesion promoter, od.dergl. connect.

Die hier dargestellte Möglichkeit der Matrixisolation erzeugt Isolationen, die hervorragende Eigenschaften (hoher Isolationswiderstand, Aufnahme hoher mechanischer Kräfte, wasserdicht und hydrolysebeständig, um nur einige zu nennen) besitzen. Die Verarbeitungsprozesse für die hier beschriebene Isolationsmöglichkeit lassen sich gut für eine Serienproduktion automatisiert umsetzen. Der eingesetzte Versiegelungswerkstoff ist gegenüber Werkstoffen, die mit warmvernetzenden Klebern beschichtet sind (Laminaten), sowohl ökonomisch gesehen, als auch ökologisch gesehen, wesentlich günstiger.The matrix isolation option shown here creates isolations that are excellent Properties (high insulation resistance, absorption of high mechanical forces, waterproof and hydrolysis resistant, to name just a few). The processing processes for the insulation option described here can be used for series production implement automatically. The sealing material used is opposite Materials that are coated with heat-curing adhesives (laminates), both Economically, as well as ecologically, much cheaper.

Die Erfindung wird im folgenden an Hand der Zeichnung näher erläutert. Dabei zeigen

  • die Fig. 1 bis 5 die schrittweise Abfolge der ersten Variante des erfindungsgemäßen Verfahrens und
  • die Fig. 6 bis 9 die schrittweise Abfolge der zweiten Variante der Erfindung.
    • The invention is explained below with reference to the drawing. Show
  • 1 to 5, the stepwise sequence of the first variant of the method according to the invention and
  • 6 to 9, the gradual sequence of the second variant of the invention.

    • Wie aus Fig. 1 hervorgeht, werden die bereits miteinander verbundenen FFC 2 und 3, deren Verbindungsstellen mit 4 bezeichnet sind und die gemeinsam eine Rohmatrix 1 bilden, passend zwischen zwei Stempelteilen, einem oberen Stempel 5 und einem unteren Stempel 6 positioniert.As can be seen from Fig. 1, the already connected FFC 2 and 3, their Connection points are designated 4 and together form a raw matrix 1, fits between two stamp parts, an upper stamp 5 and a lower stamp 6 positioned.

    Sodann wird, wie in Fig. 2 schematisch gezeigt, durch eine Abgabevorrichtung für Versiegelungsmaterial dieses Versiegelungsmaterial in flüssiger bzw. pastöser Form auf den unteren Stempel 6 im Bereich von dessen Kontakt mit der Rohmatrix 1 aufgebracht, diese aufgebrachte Menge ist schematisch mit 8 angedeutet. Wie bereits oben ausgeführt, ist der verwendete Versiegelungswerkstoff entweder der gleiche Werkstoff, wie das Isolationsmaterial, mit dem in den FFC's 2 und 3 die Leiter umhüllt sind, oder es handelte sich um einen ähnlichen Werkstoff, der mit diesem Isolationsmaterial leicht, gut und dauerhaft verbindbar ist und sich so für das Umspritzen der Rohmatrix eignet.Then, as shown schematically in Fig. 2, by a dispenser for sealing material this sealing material in liquid or pasty form on the bottom Stamp 6 applied in the area of its contact with the raw matrix 1, this applied amount is indicated schematically with 8. As already explained above, the sealing material used either the same material as the insulation material, with which the conductors are wrapped in FFC's 2 and 3, or it was a similar material that can be easily, permanently and permanently connected with this insulation material and is therefore suitable for the extrusion coating of the raw matrix.

    In Fig. 3 ist das Aufbringen des Versiegelungswerkstoffes auf die Rohmatrix 1 dargestellt, dadurch erhält man eine ausreichende Menge an Versiegelungswerkstoff, um die Form um die Rohmatrix 1 herum auszufüllen und so zuverlässig zu einer allseitigen Isolierung der Rohmatrix 1 zu kommen. 3 shows the application of the sealing material to the raw matrix 1, this provides a sufficient amount of sealing material to change the shape fill out the raw matrix 1 around and thus reliably provide all-round insulation Raw matrix 1 to come.

    Es ist selbstverständlich möglich, die in Fig. 2 und 3 dargestellten Schritte in ihrer Reihenfolge zu vertauschen oder auch diese Schritte simultan vorzunehmen, indem man einen eigenen Spender für jede der beiden Aufbringungsstellen wählt.It is of course possible to sequence the steps shown in FIGS. 2 and 3 to swap or to perform these steps simultaneously by one chooses its own donor for each of the two application sites.

    In Fig. 4 ist die Situation bei geschlossener Form dargestellt, durch Anwenden von Druck und Temperatur erfolgt das Verbinden des Versiegelungswerkstoffes mit dem Isoliermaterial der FFC und das Aushärten des Versiegelungswerkstoffes.4 shows the situation with the mold closed, by applying pressure and temperature, the sealing material is connected to the insulating material the FFC and the curing of the sealing material.

    Die Fig. 5 zeigt die Situation nach erfolgter Aushärtung, wenn die Stempel, entweder gleichzeitig oder nacheinander, auseinander bewegt werden. Dargestellt ist die Situation, bei der der obere Stempel 5 mit der zugehörigen oberen Hälfte der Form abgehoben ist, die fertige Matrix 1' aber noch am unteren Stempel 6 liegt. Es kann sodann entweder die Matrix 1' angehoben oder der Stempel 6 abgesenkt werden, um die fertige Matrix entnehmen und weiter behandeln zu können.Fig. 5 shows the situation after curing, when the stamp, either at the same time or one after the other. The situation is shown in which the upper punch 5 is lifted off with the associated upper half of the mold which finished matrix 1 'but is still on the lower punch 6. It can then either be the matrix 1 'raised or the punch 6 lowered to remove the finished matrix and to be able to treat further.

    Auf ähnliche Weise erfolgt im Zuge der Herstellung einer erfindungsgemäßen Matrix gemäß der zweiten Variante der Erfindung die Abfolge der Darstellung gemäß den Fig. 6 bis 9, wobei zur besseren Vergleichbarkeit einander entsprechende Elemente mit den gleichen Bezugszeichen wie bei der ersten Variante der Erfindung, aber einer vorgestellten Ziffer "1" bezeichnet wurden, während gleiche Teile das gleiche Bezugszeichen erhielten.Similarly, in the course of the production of a matrix according to the invention the second variant of the invention, the sequence of the representation according to FIGS. 6 to 9, wherein for better comparability, corresponding elements with the same Reference numerals as in the first variant of the invention, but a number presented "1" was designated while the same parts were given the same reference numerals.

    In Fig. 6 erkennt man die beiden Stempel 15 und 16, die gegebenenfalls an ihren Stempelflächen, die zueinander gerichtet sind, eine Kontur aufweisen können oder elastisch ausgebildet sein können, um sich der Kontur der Matrix besser anpassen zu können. Auf den beiden Stempelflächen ist das Versiegelungsmaterial in Form von Folien 18, 19 angeordnet. Dies kann durch Anlegen eines Vakuums oder durch Verwenden eines schwachen Klebstoffes sichergestellt werden.In Fig. 6 you can see the two stamps 15 and 16, possibly on their stamp surfaces, which are directed towards each other, can have a contour or are designed to be elastic can be to better adapt to the contour of the matrix. On the The sealing material is arranged in the form of foils 18, 19 on both stamp surfaces. This can be done by applying a vacuum or by using a weak one Glue can be ensured.

    Wie aus Fig. 7 hervorgeht, wird die Rohmatrix sodann, passend positioniert, zwischen die beiden Stempel 15, 16 gebracht und es werden die Stempel 15, 16, wie in Fig. 8 gezeigt, geschlossen. Sodann wird durch Anwenden von Druck und Temperatur die Verbindung zwischen den Folien 18, 19 und der Oberfläche der Rohmatrix 1 gebildet und es werden die Folien 18, 19, sofern dies nicht bereits vor der Verbindung der Fall war, auch passend ausgehärtet. Dies ist insbesondere dann der Fall, wenn, was bei dieser Variante bevorzugt wird, die Folienteile in Form sogenannter Prepregs vorliegen, wie dies auf dem Gebiet der Kunststofftechnologie dem Fachmann geläufig ist.7, the raw matrix is then suitably positioned between the brought both stamps 15, 16 and there are the stamps 15, 16, as shown in Fig. 8, closed. Then the connection is made by applying pressure and temperature formed between the foils 18, 19 and the surface of the raw matrix 1 and there are the films 18, 19, if this was not already the case before the connection, also suitable hardened. This is particularly the case if what is preferred in this variant is, the film parts are in the form of so-called prepregs, as in the field of Plastic technology is familiar to the expert.

So ist es insbesondere möglich, die Bewegung der beiden Stempel zueinander bei jeder der beiden Varianten anders zu gestalten als im dargestellten Ausführungsbeispiel, es können sich beide Stempel bewegen oder nur einer der Stempel, es kann diese Bewegung entweder, wie dargestellt, eine Linearbewegung oder, wie in der Automatisierung auch üblich, eine Schwenk- bzw. Klapp-, Roll- oder Drehbewegung sein, dies ist vom Fachmann auf dem Gebiet der Kunststoffverarbeitung in Kenntnis der Erfindung und in Kenntnis der ihm zur Verfügung stehenden Geräte bzw. der Nachbarstationen leicht auswählbar.Of course, the invention is not limited to the exemplary embodiments shown, but can be changed and modified in various ways. It is so in particular possible the movement of the two stamps towards each other in each of the two To design variants differently than in the illustrated embodiment, it can both stamps move or only one of the stamps, this movement can either, as shown, a linear movement or, as is also common in automation, a Swiveling or folding, rolling or rotating movement, this is the specialist on the Field of plastics processing with knowledge of the invention and with knowledge of it Available devices or neighboring stations can be easily selected.

    So ist es auch möglich, in Abwandlungen der dargestellten Beispiele, die Form der Isolation zu ändern (z.B. rund, dreieckig, rechteckig) und es kann je nach Anwendungsfall die Lage der Isolation auf der Matrix anders sein als dargestellt.So it is also possible, in modifications of the examples shown, the form of isolation to change (e.g. round, triangular, rectangular) and depending on the application, the Location of the insulation on the matrix may be different than shown.
