- the holding element 14 has a first connecting element 16, here in the form of a stop shoulder 18.
- the holding element 14 is leaf-shaped formed, in the example as a thin flat plastic strip, and has an opening 20.
- a portion 21 of the opening 20, namely here the end 6 reheatender edge portion 22 forms the first connecting element 16.
- the holding member 14 has a T-shape, wherein a transverse leg 24 of the T-shape in Fig. 1 indicated by dashed lines, the flat side 12 facing mounting surface 26 includes.
- the attachment surface 26 is here an adhesive surface, by means of which the holding element 14 attached to the film cable 2 or cable body 4, is glued here.
- the first connecting element 16 is arranged on a longitudinal limb 28 of the T-shape or of the retaining element 14.
- the holding element 14 has a width b1 which is equal to the width b2 of the film cable 2. Thus, no protrusion between retaining element 14 and foil cable 2 is formed.
- the width b1 is given only for the transverse limb 24.
- the longitudinal leg 28 has a smaller width b3, in the example about half of the width b1, on.
- the holding element 14 is also designed to be flexible, so that in particular the free, not directly attached to the film cable 2 longitudinal leg 28 can articulate from the flat side 12. So this provides a spring travel F for a further explained below locking.
- the spring travel F is in Fig. 1 indicated by an arrow.
- Fig. 2 shows 2 next to the film cable Fig. 1
- the film cable 2 is inserted as far as possible into the connector 30, so that a large part of the Kunststofftechniksbartes 8 in the connector 30 rests.

Die Erfindung betrifft eine Haltevorrichtung zum Halten eines Folienkabels in einem Steckverbinder, einen Steckverbinder, ein Folienkabel und ein Folienkabelsystem.The invention relates to a holding device for holding a foil cable in a connector, a connector, a foil cable and a foil cable system.
In Rede stehende Folienkabel dienen in der Regel der Übertragung von Informationssignalen und werden derzeit millionenfach produziert und in nahezu allen Bereichen der Technik eingesetzt. Lediglich beispielhaft seien Unterhaltungselektronik, Haushaltsgeräte und Kraftfahrzeuge genannt. Folienkabel im Sinne der vorliegenden Erfindung sind insbesondere sogenannte FFC(Flat Flexible Cable)- oder FPC(Flat Printed Circuit)-Kabel. Solche Folienkabel weisen an einem stirnseitigen Ende einen Kontaktierungsbart auf. Dort sind die elektrischen Leiter des Kabels zugänglich und können kontaktiert werden. Beim elektrischen Anschluss eines Folienkabels wird dieses mit dem Kontaktierungsbart an ein entsprechendes Gegenstück angelegt dort elektrisch kontaktiert. Insbesondere soll aber auch verhindert werden, dass sich das Folienkabel aus der Kontaktierung wieder löst, also eine sogenannte Zugentlastung für das Kabel geschaffen werden.Film cords in question generally serve to transmit information signals and are currently being produced by the millions and used in almost all areas of technology. Only by way of example entertainment electronics, household appliances and motor vehicles are mentioned. Foil cables in the sense of the present invention are in particular so-called FFC (Flat Flexible Cable) or FPC (Flat Printed Circuit) cable. Such foil cables have a Kontaktierungsbart at one end face. There, the electrical conductors of the cable are accessible and can be contacted. When electrical connection of a foil cable this is applied with the Kontaktierungsbart to a corresponding counterpart contacted there electrically. In particular, but should also be prevented that the film cable from the contact again dissolves, so a so-called strain relief for the cable can be created.
Beispielsweise aus dem
In neuerer Zeit werden üblicherweise keine Pfostenstecker zur Kontaktierung mehr benutzt, sondern auf einer Platine ein integraler Steckverbinder aufgebracht, welcher seinerseits Kontaktierungselemente für den Kontaktierungsbart des Folienkabels enthält. Ein derartiger Steckverbinder ist beispielsweise aus der Schrift
Aufgabe der vorliegenden Erfindung ist es, die Halterung eines Folienkabels in einem Steckverbinder zu verbessern.Object of the present invention is to improve the mounting of a foil cable in a connector.
Die Aufgabe wird hinsichtlich einer Haltevorrichtung gelöst durch eine solche gemäß Patentanspruch 1. Die Haltevorrichtung dient zum Halten eines Folienkabels in einem Steckverbinder. Das Folienkabel wird bei der Montage bzw. elektrischen Kontaktierung entlang einer Einsteckrichtung in den Steckverbinder eingesteckt. Die Haltevorrichtung enthält ein Halteelement, welches am Folienkabel anbringbar ist. Das Halteelement weist ein erstes Verbindungselement auf. Die Haltevorrichtung umfasst auch ein zweites Verbindungselement, welches am Steckverbinder anbringbar ist, wobei die Formulierung "anbringbar" auch "angebracht" einschließt. Das zweite Verbindungselement ist mit dem ersten Verbindungselement derart verriegelbar, dass eine Bewegung des Halteelements relativ zum zweiten Verbindungselement entgegen einer Einsteckrichtung verhindert ist. Da eine Bewegung zwischen Halteelement und zweitem Verbindungselement verhindert ist und spätestens im Betrieb bzw. einem Montagezustand das Halteelement am Folienkabel, und das zweite Verbindungselement am Steckverbinder tatsächlich angebracht ist, ist auch eine Relativbewegung zwischen Steckverbinder und Folienkabel verhindert. Mit anderen Worten verhindert die Haltevorrichtung eine Bewegung des Folienkabels zum Steckverbinder im montierten Zustand, d. h. wenn das Folienkabel im Steckverbinder elektrisch kontaktierend einliegt.The object is achieved in terms of a holding device by such a device according to claim 1. The holding device is used to hold a foil cable in a connector. The film cable is inserted during assembly or electrical contact along a plug in the connector. The holding device includes a holding element, which is attachable to the film cable. The holding element has a first connecting element. The holding device also includes a second connecting element which is attachable to the connector, wherein the wording "attachable" also includes "attached". The second connecting element can be locked to the first connecting element such that a movement of the holding element relative to the second connecting element is prevented against a plug-in direction. Since movement between the retaining element and the second connecting element is prevented and at the latest during operation or a mounting state the retaining element on the film cable, and the second connecting element is actually attached to the connector, a relative movement between the connector and the film cable is prevented. In other words, the holding device prevents movement of the film cable to the connector in the mounted state, d. H. when the film cable rests in the connector electrically contacting.
Das Halteelement ist an einer Flachseite des Folienkabels anbringbar Die Breite des Halteelements ist zumindest annähernd gleich oder kleiner als die Breite des Folienkabels. Die Verbindung an der Flachseite des Folienkabels bedeutet, dass das Halteelement nur dort und nirgends sonst befestigt ist; insbesondere erfolgt die Befestigung also ohne Durchdringung des Kabels nur an dessen Oberfläche und auch nicht durch wenigstens teilweises Umgreifen von Seitenkanten des Folienkabels. Insbesondere ist dann auch das gesamte Halteelement gänzlich auf einer Flachseite des Folienkabels gelegen, umgreift dieses also auch nicht teilweise. Das Halteelement weist daher in der Regel eine Befestigungsfläche für die Befestigung am Folienkabel auf. Die Befestigungsfläche ist beispielsweise eine Klebe- Schweiß- oder sonstige Befestigungsfläche, wodurch z.B. Ankleben, Anschweißen oder Anformen des Halteelements am Folienkabel möglich ist. Anformen geschieht z.B. durch nachträgliches oder integrales Anspritzen nach oder bei der Herstellung des Kabels.The holding element can be attached to a flat side of the film cable. The width of the holding element is at least approximately equal to or smaller than the width of the film cable. The connection on the flat side of the Foil cable means that the retaining element is attached only there and nowhere else; In particular, the attachment thus takes place without penetrating the cable only on its surface and not by at least partially encompassing side edges of the foil cable. In particular, then the entire holding element is located entirely on a flat side of the foil cable, this embraces not so partially. The retaining element therefore generally has a mounting surface for attachment to the film cable. The attachment surface is, for example, an adhesive welding or other attachment surface, whereby, for example, gluing, welding or molding of the retaining element on the film cable is possible. Forming is done, for example, by subsequent or integral molding after or during the manufacture of the cable.
Die Haltevorrichtung umfasst insbesondere keine weiteren, der Verriegelung dienenden Elemente: Nur die genannten Elemente sind für die Verriegelung notwendig und auch vorhanden. Insbesondere ist also das Halteelement nicht Teil eines weiteren, am Folienkabel anbringbaren Elements. Insbesondere ist die Breite des Halteelements tatsächlich kleiner oder gleich derjenigen des Folienkabels, mit anderen Worten existiert dann kein seitlicher Überstand des Halteelements über das Folienkabel hinaus.The holding device comprises in particular no further, the locking serving elements: Only the said elements are necessary for the lock and also available. In particular, therefore, the holding element is not part of another, attachable to the film cable element. In particular, the width of the retaining element is actually smaller than or equal to that of the foil cable, in other words, no lateral projection of the retaining element then exists beyond the foil cable.
Das zweite Verbindungselement ist in einer bevorzugten Ausführungsform der Erfindung an einer Umfangsfläche des Steckverbinders anbringbar. Die Umfangsflächen sind die bezüglich der Achse der Einsteckrichtung in Umfangsrichtung liegenden Flächen eines Steckverbinders, die also jedenfalls nicht senkrecht zur Einsteckrichtung verlaufen. So kann ein entsprechender Steckverbinder trotz der Haltevorrichtung stehend oder liegend auf einer Platine angeordnet werden.The second connecting element can be attached in a preferred embodiment of the invention to a peripheral surface of the connector. The peripheral surfaces are with respect to the axis of the insertion direction in the circumferential direction surfaces of a connector, which therefore in any case not perpendicular to the insertion direction. Thus, a corresponding connector in spite of the holding device can be arranged standing or lying on a circuit board.
In einer bevorzugten Ausführungsform weisen die Verbindungselemente Mittel einer Rastverbindung auf. Die Rastverbindung ist eine solche, die beim Einstecken des Folienkabels in den Steckverbinder einrastet und somit die oben genannte Verriegelung bewirkt. Insbesondere handelt es sich hierbei um eine formschlüssig hintergreifende Rastverbindung. Insbesondere erfolgt die Verriegelung automatisch beim Einstecken.In a preferred embodiment, the connecting elements have means of a latching connection. The latching connection is one which engages when plugging the foil cable into the connector and thus causes the above-mentioned locking. Especially this is a form-locking engaging latching connection. In particular, the locking takes place automatically when plugging.
In einer weiteren bevorzugten Ausführungsform enthält das erste Verbindungselement eine Anschlagschulter, das zweite Verbindungselement enthält eine Rastnase, welche bei der Verriegelung die Anschlagschulter hintergreift. Rastnase und Anschlagschulter eignen sich besonders zur Herstellung einer oben genannten Rastverbindung. Insbesondere wenn die Rastnase in bekannter Weise gefedert ist, kann diese federnd über die Anschlagschulter gleiten und sich so eine automatisch beim Einstecken verriegelnde Verrastung ergeben.In a further preferred embodiment, the first connecting element includes a stop shoulder, the second connecting element includes a latching nose, which engages behind the stop shoulder in the locking. Locking lug and stop shoulder are particularly suitable for producing an above-mentioned locking connection. In particular, when the latch is spring-loaded in a known manner, this can slide resiliently over the stop shoulder and thus result in an automatically locking when inserting latching.
In einer weiteren bevorzugten Ausführungsform ist das erste Verbindungselement einstückig mit dem Halteelement ausgeführt. Alternativ oder zusätzlich ist das zweite Verbindungselement einstückig mit dem Steckverbinder ausgeführt. Insbesondere hier sind die erstes und zweites Verbindungselement also an dem jeweiligen Gegenstück nicht im engen Sinne anbringbar, sondern in der Regel bereits angebracht, d. h. angespritzt, angeformt usw.. Der Steckverbinder oder das Halteelement weisen dann mit anderen Worten jeweils einen Teil der Haltevorrichtung auf.In a further preferred embodiment, the first connecting element is designed in one piece with the retaining element. Alternatively or additionally, the second connecting element is designed in one piece with the plug connector. In particular, here are the first and second connecting element so not attached to the respective counterpart in the strict sense, but usually already attached, d. H. injected, molded, etc. The connector or the holding element then have in each case in each case a part of the holding device.
In einer weiteren bevorzugten Ausführungsform ist das Halteelement blattförmig ausgebildet. Das heißt, das Halteelement ist im Wesentlichen rein flächig bzw. beidseitig eben, also beispielsweise band-, streifen- oder scheibenförmig ausgebildet.In a further preferred embodiment, the holding element is sheet-shaped. That is, the holding element is substantially flat or flat on both sides, so for example, band, strip or disc-shaped.
In einer weiteren bevorzugten Ausführungsform weist das Halteelement eine Durchbrechung auf. Zumindest ein Teil der Durchbrechung bildet zumindest einen Teil des ersten Verbindungselements. Insbesondere kann beispielsweise ein Randabschnitt der Durchbrechung die oben genannte Anschlagschulter bilden.In a further preferred embodiment, the holding element has an opening. At least part of the opening forms at least a part of the first connecting element. In particular, for example, an edge portion of the opening form the abovementioned stop shoulder.
Das Halteelement kann auch eine T-Form aufweisen, wobei ein Querschenkel des Halteelements bzw. der T-Form eine Befestigungsfläche zur Befestigung am Folienkabel aufweist. Ein Längsschenkel des Halteelements bzw. der T-Form weist dagegen das erste Verbindungselement auf. Beispielsweise ist hier der Querschenkel so breit wie das Folienkabel ausgeführt, der Längsschenkel allerdings schmäler. Die T-Form ist dann insbesondere in Einsteckrichtung ausgerichtet, d. h. der Längsschenkel weist zum Steckverbinder hin.The holding element may also have a T-shape, wherein a transverse leg of the holding element or the T-shape has a mounting surface for attachment to the film cable. A longitudinal leg of the holding element or the T-shape, however, has the first connecting element. For example, here is the transverse leg as wide as the foil cable executed, the longitudinal leg, however, narrower. The T-shape is then aligned in particular in the insertion direction, d. H. the longitudinal leg points towards the connector.
In einer weiteren bevorzugten Ausführungsform ist das Halteelement flexibel ausgebildet. Die Flexibilität ist dahingehend zu verstehen, dass das Halteelement durch seine Verformung einen Federweg für die Verriegelung der Verbindungselemente aufweist. Dies gilt insbesondere für die oben genannte Rastverbindung mit einer starren Rastnase am starren Steckverbinder. Das erste Verbindungselement in Form der Anschlagschulter federt dann flexibel mit dem Halteelement beim Einsteckvorgang über die Rastnase, um anschließend hinter dieser zurückzufedern und zu verrasten. Alternativ oder zusätzlich kann ein derartiger Federweg auch durch eine Bewegung bzw. eine elastische Verbiegung des Folienkabels bereitgestellt werden. Insbesondere sind bei den genannten Ausführungsformen dann keine separaten beweglichen Teile wie Hebel, Federn oder ähnliches nötig. Die zur Verrastung notwendigen Federwege werden allein durch die genannten Bauteile selbst dargestellt. Besonders eignet sich der schmalere Längsschenkel der o.g. T-Form zur Ausbildung eines federnden Elements, das dann das erste Verbindungselement trägt. Der breitere Querschenkel dagegen ist mechanisch stabiler und dient der Befestigung am Folienkabel.In a further preferred embodiment, the holding element is flexible. The flexibility is to be understood that the holding element by its deformation has a spring travel for the locking of the connecting elements. This is especially true for the above-mentioned locking connection with a rigid locking lug on the rigid connector. The first connecting element in the form of the stop shoulder then flexibly springs with the retaining element during the insertion process via the latching lug, in order subsequently to spring back and lock behind the latching lug. Alternatively or additionally, such a spring travel can also be provided by a movement or an elastic bending of the foil cable. In particular, in the embodiments mentioned no separate moving parts such as levers, springs or the like are necessary. The spring travel necessary for latching are represented solely by the mentioned components themselves. Especially the narrower longitudinal leg of the o.g. T-shape for forming a resilient element, which then carries the first connecting element. The wider transverse leg, on the other hand, is mechanically more stable and serves for fastening to the foil cable.
Hinsichtlich des Steckverbinders wird die Aufgabe der Erfindung durch einen Steckverbinder gemäß Patentanspruch 9 gelöst, welcher das zweite Verbindungselement einer erfindungsgemäßen Haltevorrichtung aufweist.With regard to the connector, the object of the invention is achieved by a connector according to claim 9, which has the second connecting element of a holding device according to the invention.
Hinsichtlich eines Folienkabels wird die Aufgabe der Erfindung durch ein Folienkabel gemäß Anspruch 10 gelöst, an dem das Halteelement einer erfindungsgemäßen Haltevorrichtung angebracht ist.With regard to a foil cable, the object of the invention is achieved by a foil cable according to
Hinsichtlich eines Folienkabelsystems wird die Aufgabe der Erfindung gelöst durch ein Folienkabelsystem gemäß Patentanspruch 11. Dieses umfasst einen erfindungsgemäßen Steckverbinder und ein erfindungsgemäßes Folienkabel und damit auch die erfindungsgemäße Haltevorrichtung.With regard to a film cable system, the object of the invention is achieved by a film cable system according to claim 11. This comprises a connector according to the invention and a film cable according to the invention and thus also the holding device according to the invention.

An der Flachseite 12 des Folienkabels 2 ist ein Halteelement 14 angebracht. Das Halteelement 14 weist ein erstes Verbindungselement 16, hier in Form einer Anschlagschulter 18 auf. Das Halteelement 14 ist blattförmig ausgebildet, im Beispiel als dünner flacher Kunststoffstreifen, und weist eine Durchbrechung 20 auf. Ein Teil 21 der Durchbrechung 20, nämlich hier deren zum Ende 6 hinweisender Randabschnitt 22 bildet das erste Verbindungselement 16. Das Halteelement 14 weist eine T-Form auf, wobei ein Querschenkel 24 der T-Form eine in
Das Halteelement 14 weist eine Breite b1 auf, welche gleich der Breite b2 des Folienkabels 2 ist. So entsteht kein Überstand zwischen Halteelement 14 und Folienkabel 2. Im Ausführungsbeispiel ist die Breite b1 nur für den Querschenkel 24 gegeben. Der Längsschenkel 28 weist eine geringere Breite b3, im Beispiel etwa die Hälfte der Breite b1, auf. Das Halteelement 14 ist außerdem flexibel ausgebildet, so dass sich insbesondere der freie, nicht direkt am Folienkabel 2 befestigte Längsschenkel 28, gelenkig von der Flachseite 12 abheben kann. So stellt dieser einen Federweg F für eine weiter unten erläuterte Verriegelung bereit. Der Federweg F ist in
Am Steckverbinder 30 ist ein zweites Verbindungselement 34 angebracht, hier in Form einer Rastnase 36, welches mit dem ersten Verbindungselement 16 verriegelt ist. Die Verriegelung ist derart geschaffen, dass die Rastnase 36 formschlüssig die Anschlagschulter 18 hintergreift. Beide Verbindungselemente 16,34 bilden daher Mittel 17,35 eine Rastverbindung 37. Eine Bewegung des Halteelements 14 bezüglich des zweiten Verbindungselements 34 entgegen der Einsteckrichtung 32 ist damit verhindert. Da das Halteelement 14 außerdem am Kabelkörper 4 und das zweite Verbindungselement 34 am Steckverbinder 30 befestigt ist, ist auch eine Bewegung des Folienkabels 2 aus dem Steckverbinder 30 entgegen der Einsteckrichtung 32 verhindert. Die o.g. sichere elektrische Verbindung bleibt so erhalten. Das Halteelement 14 zusammen mit den beiden Verbindungselementen 16,34 bilden so zusammen eine Haltevorrichtung 43.At the
An derjenigen Umfangsfläche 40, an welcher das zweite Verbindungselement 34 angebracht ist, ist außerdem eine Auflaufschräge 52 vorgesehen. Dort ist der Steckverbinder 30 zur Einstecköffnung 31 hin abgeflacht bzw. verjüngt. Die Auflaufschräge 52 weist hier in etwa die Breite b3 des Halteelements 14, bzw. hier des Längsschenkels 28 auf. Beim Einstecken des Folienkabels 2 gleitet das Halteelement 14 auf die Auflaufschräge 52 auf und erreicht so leichter die Umfangsfläche 40 des Steckverbinders 30. Hierdurch hebt auch der Längsschenkel 28 leichter bzw. beim Einstecken automatisch von der Flachseite 12 des Folienkabels 2 ab.On the
