Description

Die Erfindung betrifft ein Verbindungsstück für eine elektrische Verbindung zur Verbindung mit einem korrespondierenden Verbindungsgegenstück durch Aufstecken in einer Verbindungsrichtung, ein korrespondierendes Verbindungsgegenstück und ein elektrisches Verbindungssystem aus einem Verbindungsstück und einem Verbindungsgegenstück.The invention relates to a connector for an electrical connection for connection to a corresponding connection counterpart by plugging in a connection direction, a corresponding connection counterpart and an electrical connection system of a connector and a connection counterpart.

Zum Beispiel in vielen Abdeckungs- oder Verkleidungselementen eines Fahrzeugs wie zum Beispiel der Türverkleidung oder dem Dachhimmel befinden sich eine große Anzahl an Schaltern, Beleuchtungen, Bedienelementen und Sensoren. Diese Elemente werden bei bekannten Lösungen durch viele einzelne Stecker kontaktiert. Während der Montage der meist großflächigen Verkleidungen werden auf der Rückseite zuerst die einzelnen Stecker per Hand, teils über Kopf, mühsam und zeitraubend zusammengesteckt, wobei es auch zu Fehlsteckungen kommen kann. Erst im Anschluss erfolgt die Endmontage durch Verklipsen oder Verschrauben mit dem Fahrzeug. Diese Art der Montage ist aufwändig und weist viele Prozessschritte auf. Insbesondere beim Reparaturfall ist der Demontage- und Montagevorgang erschwert.For example, in many cover or trim elements of a vehicle, such as the door trim or the headliner, there are a large number of switches, lights, controls, and sensors. These elements are contacted in known solutions by many individual plugs. During the assembly of the mostly large-scale panels, the individual plugs are put together on the back first by hand, partly overhead, tedious and time-consuming, which can also lead to mis-insertion. Only then is the final assembly by clipping or screwing with the vehicle. This type of assembly is complex and has many process steps. Especially in case of repair, the disassembly and assembly process is difficult.

DE 945 577 C beschreibt ein Verbindungsstück für eine elektrische Verbindung zur Verbindung mit, einem korrespondierenden Verbindungsgegenstück durch Aufstecken in einer Verbindungsrichtung. Das Verbindungsstück umfasst einen Träger und einen Kontaktierungshalter, der bewegbar gelagert ist. Der Träger weist einen ersten, vom Kontaktierungshalter beabstandeten, sich senkrecht zur Verbindungsrichtung erstreckenden Vorsprung auf. Der Vorsprung ist derart ausgestaltet, dass er hinter einen korrespondierenden zweiten Vorsprung eines korrespondierenden Verbihdungsgegenstückes hintergreifen kann. Außerdem sind elektrische Kontakte in dem ersten Kontaktierungshalter vorgesehen.DE 945 577 C describes a connector for an electrical connection for connection to, a corresponding connection counterpart by plugging in a connecting direction. The connector comprises a carrier and a Kontaktierungshalter, which is movably mounted. The carrier has a first, spaced from the contacting holder, extending perpendicular to the connecting direction projection. The projection is designed such that it can engage behind a corresponding second projection of a corresponding Verbihdungsgegenstückes. In addition, electrical contacts are provided in the first contacting holder.

Aufgabe der vorliegenden Erfindung ist es, ein elektrisches Verbindungssystem, ein Verbindungsstück für ein solches System und ein Verbindungsgegenstück für ein solches System anzugeben, die eine einfache und sichere Montage gewährleisten.Object of the present invention is to provide an electrical connection system, a connector for such a system and a connection counterpart for such a system, which ensure a simple and secure installation.

Diese Aufgabe wird mit einem Verbindungsstück für eine elektrische Verbindung mit den Merkmalen des Anspruchs 1, ein Verbindungsgegenstück für eine elektrische Verbindung mit den Merkmalen des Anspruchs 7 und ein elektrisches Verbindungssystem mit den Merkmalen des Anspruchs 9 gelöst. Eine vorteilhafte Anwendung ist Gegenstand des Anspruchs 12.This object is achieved with a connector for an electrical connection with the features of claim 1, a connection counterpart for an electrical connection with the features of claim 7 and an electrical connection system with the features of claim 9. An advantageous application is the subject of claim 12.

Im vorliegenden Text werden die Elemente des Verbindungsstückes jeweils als "erste" Elemente und die Elemente eines korrespondierenden Verbindungsgegenstückes jeweils als "zweite" Elemente bezeichnet.In the present text, the elements of the connecting piece are respectively referred to as "first" elements and the elements of a corresponding connecting counterpart in each case as "second" elements.

Das erfindungsgemäße Verbindungsstück weist einen ersten Träger auf, an dem ein erster Kontaktierungshalter in einer Richtung bewegbar gelagert ist, die eine Komponente aufweist, die senkrecht zur Verbindungsrichtung ist.The connecting piece according to the invention has a first carrier, on which a first contacting holder is movably mounted in a direction which has a component which is perpendicular to the connecting direction.

Die Verbindungsrichtung bezeichnet dabei die Richtung, in der das Verbindungsstück und das korrespondierende Verbindungsgegenstück zueinander bewegt werden, um eine elektrische Verbindung herzustellen.The connecting direction designates the direction in which the connecting piece and the corresponding connecting counterpart are moved relative to one another in order to establish an electrical connection.

Der erste Kontaktierungshalter weist wenigstens einen ersten, vom ersten Kontaktierungshalter beabstandeten, sich senkrecht zur Verbindungsrichtung erstreckenden Vorsprung auf, der derart ausgestaltet ist, dass er bei einer Bewegung des ersten Kontaktierungshalters in Richtung seiner beweglichen Lagerung hinter einen korrespondierenden zweiten Vorsprung eines korrespondierenden Verbindungsgegenstückes hintergreifen kann. Durch dieses Hintergreifen wird ein Verrasten der Vorsprünge bewirkt, das das Verbindungsstück und Verbindungsgegenstück aneinander fixiert.The first contacting holder has at least one first, spaced from the first contacting holder, perpendicular to the connecting direction projection which is configured such that it can engage behind a corresponding second projection of a corresponding connection counterpart in a movement of the first Kontaktierungshalters in the direction of its movable mounting behind. By this engaging behind a locking of the projections is effected, which fixes the connecting piece and connecting counterpart together.

Das erfindungsgemäße Verbindungsstück weist wenigstens einen elektrischen Kontakt in dem ersten Kontaktierungshalter auf, der sich im Wesentlichen senkrecht zur Verbindungsrichtung erstreckt.The connector according to the invention has at least one electrical contact in the first contacting holder, which extends substantially perpendicular to the connecting direction.

Ein erstes, bezüglich des ersten Trägers des Verbindungsstückes ortsfestes Positionierungselement ist am ersten Träger vorgesehen, um mit einem korrespondierenden zweiten Positionierungselement eines korrespondierenden Verbindungsgegenstückes derart zusammenzuwirken, dass der erste Träger in Verbindungsrichtung geführt wird. Das Positionierungselement dient insofern dazu, dass beim Zusammenführen des Verbindungsstückes und des Verbindungsgegenstückes keine seitliche Versetzung des ersten Trägers des Verbindungsstückes bezüglich des Verbindungsgegenstückes erfolgen kann.A first, with respect to the first carrier of the connecting piece stationary positioning member is provided on the first carrier to cooperate with a corresponding second positioning element of a corresponding connection counterpart such that the first carrier is guided in the connecting direction. The positioning element serves to the extent that during the merging of the connecting piece and the connecting counterpart no lateral displacement of the first carrier of the connecting piece can take place with respect to the connection counterpart.

Das erfindungsgemäße Verbindungsstück weist zudem eine Kulissenführung auf, die derart ausgestaltet ist, dass bei einer relativen Bewegung des ersten Trägers und des ersten Kontaktierungshalters in der Verbindungsrichtung eine weitere Bewegung des ersten Kontaktierungshalters selbsttätig ausgelöst wird, die senkrecht zur Verbindungsrichtung in Richtung der beweglichen Lagerung des ersten Kontaktierungshalters ist. Werden der erste Kontaktierungshalter und der erste Träger also relativ zueinander bewegt, entsteht eine Bewegung mit einer Komponente in Verbindungsrichtung und einer Komponente senkrecht dazu.The connector according to the invention also has a slotted guide, which is designed such that upon relative movement of the first carrier and the first Kontaktierungshalters in the connecting direction, a further movement of the first Kontaktierungshalters is triggered automatically, perpendicular to the connecting direction in the direction of the movable mounting of the first Contacting holder is. Thus, if the first contacting holder and the first carrier are moved relative to one another, a movement arises with a component in the connecting direction and a component perpendicular thereto.

Ein erfindungsgemäßes Verbindungsgegenstück eignet sich insbesondere als korrespondierendes Verbindungsgegenstück zur Bildung einer elektrischen Verbindung mit einem erfindungsgemäßen Verbindungsstück. Das erfindungsgemäße Verbindungsgegenstück weist einen zweiten Träger mit einem zweiten Kontaktierungshalter auf, wobei der zweite Kontaktierungshalter wenigstens einen zweiten, vom zweiten Träger beabstandeten, sich senkrecht zur Verbindungsrichtung erstreckenden Vorsprung aufweist. Dieser zweite Vorsprung ist derart ausgestaltet, dass er von einem ersten Vorsprung eines korrespondierenden Verbindungsstückes hintergriffen werden kann. Der zweite Vorsprung des erfindungsgemäßen Verbindungsgegenstückes wirkt dementsprechend mit einem ersten Vorsprung eines Verbindungsstückes derart zusammen, dass das Verbindungsgegenstück und das korrespondierende Verbindungsstück aneinander fixiert sind.A connection counterpart according to the invention is particularly suitable as a corresponding connection counterpart to form an electrical connection with a connecting piece according to the invention. The connection counterpart of the invention has a second carrier with a second contacting holder, wherein the second contacting holder has at least one second, spaced from the second carrier, has perpendicular to the direction of connection extending projection. This second projection is designed such that it can be engaged behind by a first projection of a corresponding connecting piece. The second projection of the connection counterpart according to the invention accordingly cooperates with a first projection of a connection piece such that the connection counterpart and the corresponding connection piece are fixed to one another.

Das erfindungsgemäße Verbindungsgegenstück weist einen elektrischen Kontakt in dem zweiten Kontaktierungshalter auf, der derart angeordnet ist, dass er mit dem elektrischen Kontakt eines ersten Kontaktierungshalters eines korrespondierenden Verbindungsstückes in leitendem Kontakt steht, wenn die Vorsprünge sich hintergreifen. Sind das Verbindungsgegenstück und ein korrespondierendes Verbindungsstück dementsprechend durch Hintergreifen der zweiten und ersten Vorsprünge aneinander fixiert, besteht ein elektrischer Kontakt zwischen dem wenigstens einen elektrischen Kontakt des Verbindungsgegenstückes mit wenigstens einem elektrischen Kontakt eines korrespondierenden Verbindungsstückes.The connection counterpart of the invention has an electrical contact in the second contacting holder, which is arranged such that it is in conductive contact with the electrical contact of a first contacting holder of a corresponding connecting piece when the projections engage behind. If the connection counterpart and a corresponding connection piece are fixed to one another accordingly by engaging behind the second and first projections, there is an electrical contact between the at least one electrical contact of the connection counterpart with at least one electrical contact of a corresponding connection piece.

Das erfindungsgemäße Verbindungsgegenstück weist zudem ein zweites, bezüglich des zweiten Trägers ortsfestes Positionierungselement auf, das mit einem korrespondierenden Positionierungselement eines korrespondierenden Verbindungsstückes zusammenwirken kann, um den ersten Träger eines korrespondierenden Verbindungsstückes in Verbindungsrichtung zu führen. Wird das erfindungsgemäße Verbindungsgegenstück und ein korrespondierendes Verbindungsstück relativ zueinander bewegt, dient das wenigstens eine Positionierungselement des Verbindungsgegenstückes zur Führung des korrespondierenden Positionierungselementes des Verbindungsstückes, um eine relative laterale Versetzung des Trägers des Verbindungsstückes und des Verbindungsgegenstückes zu verhindern.The connection counterpart of the invention also has a second, with respect to the second carrier stationary positioning member which can cooperate with a corresponding positioning element of a corresponding connector to guide the first carrier of a corresponding connector in the connecting direction. If the connection counterpart according to the invention and a corresponding connection piece are moved relative to one another, the at least one positioning element of the connection counterpart serves to guide the corresponding positioning element of the connection piece, relative to a lateral displacement of the support to prevent the connector and the connection counterpart.

Ein erfindungsgemäßes elektrisches Verbindungssystem weist ein erfindungsgemäßes Verbindungsstück und ein erfindungsgemäßes Verbindungsgegenstück auf, die in beschriebener Weise zusammenwirken.An inventive electrical connection system has a connector according to the invention and a connection counterpart of the invention, which cooperate in the manner described.

Das erfindungsgemäße Verbindungsstück und das erfindungsgemäße Verbindungsgegenstück eines erfindungsgemäßen Verbindungssystems weisen korrespondierende Positionierungselemente auf, die insbesondere so angeordnet sind, dass die ersten Vorsprünge des Verbindungsstückes und die zweiten Vorsprünge des Verbindungsgegenstückes sich nicht behindern, wenn die Positionierungselemente zu Beginn des Verbindungsprozesses ineinander geschoben werden.The connecting piece according to the invention and the connection counterpart of a connecting system according to the invention have corresponding positioning elements, which are arranged in particular such that the first projections of the connecting piece and the second projections of the connecting counterpart do not interfere when the positioning elements are pushed into one another at the beginning of the connecting process.

Bei einer bevorzugten Ausgestaltung umfasst das erste Positionierungselement des Verbindungsstückes wenigstens einen Positionierungsbolzen und das zweite Positionierungselement des Verbindungsgegenstückes weist wenigstens eine korrespondierende Positionierungsführung, zum Beispiel eine Positionierungsöffnung, auf. Die Positionierungsführung ist derart angeordnet, dass der Positionierungsbolzen beim Zusammenführen des Verbindungsstückes und des Verbindungsgegenstückes in die Führung eingreift. Ebenso kann der wenigstens eine Positionierungsbolzen an dem Verbindungsgegenstück vorgesehen sein und die wenigstens eine korrespondierende Positionierungsführung an dem Verbindungsstück.In a preferred embodiment, the first positioning element of the connecting piece comprises at least one positioning bolt and the second positioning element of the connecting counterpart has at least one corresponding positioning guide, for example a positioning opening. The positioning guide is arranged such that the positioning pin engages in the merge of the connecting piece and the connecting counterpart in the guide. Likewise, the at least one positioning bolt may be provided on the connecting counterpart and the at least one corresponding positioning guide on the connecting piece.

Zur einfacheren Zusammenführung kann vorgesehen sein, dass der mindestens eine Positionierungsbolzen in Verbindungsrichtung konisch zuläuft.For easier integration, it can be provided that the at least one positioning bolt tapers conically in the connection direction.

Um eine solche Führung in allen seitlichen Richtungen zu gewährleisten, werden vorteilhafterweise wenigstens zwei erste Positionierungselemente mit einer entsprechenden Anzahl korrespondierender zweiter Positionierungselemente vorgesehen.In order to ensure such guidance in all lateral directions, advantageously at least two first positioning elements are provided with a corresponding number of corresponding second positioning elements.

Eine Weiterbildung des erfindungsgemäßen Verbindungsstückes weist eine Kulissenführung auf, die sich seitlich von dem ersten Kontaktierungshalter des Verbindungsstückes weg erstreckende Zapfen aufweist, die in Führungskanäle eingreifen, die an dem ersten Träger des Verbindungsstückes vorgesehen sind. Die Führungskanäle erstrecken sich in einer Ebene, die parallel zur Verbindungsrichtung ist und sind in dieser Ebene schräg zur Verbindungsrichtung angeordnet. Bewegt sich der erste Kontaktierungshalter relativ zu dem ersten Träger, gleiten die Zapfen in diesen Führungskanälen und bewirken eine seitliche Versetzung des ersten Kontaktierungshalters mit Bezug zu dem ersten Träger, auch wenn dieser nur in Verbindungsrichtung bewegt wird. Bei einer anderen Ausführungsform sind die Zapfen an dem ersten Träger vorgesehen und die Führungskanäle in dem ersten Kontaktierungshalter. Besonders vorteilhaft ist eine Ausgestaltung mit mehreren Zapfen, die in eine entsprechende Anzahl von Führungskanälen eingreifen, da dann eine besonders sichere und stabile Führung gewährleistet ist. Es ist jedoch auch eine Realisierung mit nur einem Zapfen und einem korrespondierenden Führungskanal möglich.A further development of the connecting piece according to the invention has a slotted guide which has pins extending laterally away from the first contacting holder of the connecting piece, which engage in guide channels which are provided on the first carrier of the connecting piece. The guide channels extend in a plane which is parallel to the connecting direction and are arranged in this plane obliquely to the connecting direction. When the first contacting holder moves relative to the first carrier, the pins slide in these guiding channels and cause a lateral displacement of the first contacting holder with respect to the first carrier, even if it is moved only in the connecting direction. In another embodiment, the pins are provided on the first carrier and the guide channels in the first contacting holder. Particularly advantageous is an embodiment with a plurality of pins which engage in a corresponding number of guide channels, since then a particularly secure and stable guidance is ensured. However, it is also a realization with only one pin and a corresponding guide channel possible.

Bei einer besonders vorteilhaften Weiterbildung des erfindungsgemäßen Verbindungsstückes weisen die Führungskanäle an ihrem in Verbindungsrichtung rückwärtigen Ende Bereiche auf, die parallel zur Verbindungsrichtung ausgerichtet sind und insofern nicht schräg zur Verbindungsrichtung. Diese Ausgestaltung gewährleistet eine noch sicherere elektrische Verbindung. Eine laterale Bewegung des ersten Kontaktierungshalters bezüglich des ersten Trägers des Verbindungsstückes ist in verkoppeltem Zustand bei einer solchen Ausführungsform nicht möglich. Eine solche laterale Bewegung kann zum Beispiel durch Vibrationen in einem Kraftfahrzeug hervorgerufen werden, in dem das Verbindungsstück und das Verbindungsgegenstück verwendet werden.In a particularly advantageous development of the connecting piece according to the invention, the guide channels have at their rear end in the connecting direction areas which are aligned parallel to the connecting direction and in so far not obliquely to the connecting direction. This embodiment ensures an even safer electrical connection. A lateral movement of the first contacting holder with respect to the first carrier of the connecting piece is in Coupled state not possible in such an embodiment. Such lateral movement can be caused, for example, by vibrations in a motor vehicle in which the connector and the connector counterpart are used.

Um eine optimale Ausrichtung des ersten Kontaktierungshalters in dem ersten Träger des Verbindungsstückes zu gewährleisten, wird bei einer bevorzugten Ausführungsform eine Federeinrichtung, zum Beispiel eine Spiralfeder, vorgesehen, die den ersten Kontaktierungshalter in Verbindungsrichtung von dem ersten Träger weg gegen einen Anschlag vorspannt. Dadurch ist gewährleistet, dass im nicht verbundenen Zustand des Verbindungsstückes der erste Kontaktierungshalter immer möglichst weit weg von dem ersten Träger ist, so dass die Kulissenführung beim Zusammenführen des erfindungsgemäßen Verbindungsstückes mit einem korrespondierenden Verbindungsgegenstück immer vollständig durchlaufen wird. Insbesondere bei einer Ausführtingsform, bei der die Kulissenführung Zapfen aufweist, die in korrespondierende Führungskanäle eingreifen, dient eine solche Federeinrichtung zum Vorspannen des ersten Kontaktierungshalters derart, dass die Zapfen sich am in Verbindungsrichtung vorderen Ende der Führungskanäle befinden. Der Anschlag wird hier für die Zapfen durch das Ende der Führungskanäle gebildet.In order to ensure optimum alignment of the first contacting holder in the first carrier of the connecting piece, in a preferred embodiment a spring device, for example a spiral spring, is provided, which biases the first contacting holder away from the first carrier in the connecting direction against a stop. This ensures that in the non-connected state of the connecting piece of the first contacting holder is always as far away from the first carrier, so that the slide guide is always completely completed when merging the connector according to the invention with a corresponding connection counterpart. In particular, in a Ausführtingsform in which the slotted guide has pins which engage in corresponding guide channels, such spring means for biasing the first Kontaktierungshalters such that the pins are located at the front end in the connecting direction of the guide channels. The stop is formed here for the pins through the end of the guide channels.

Die Federkraft der Federeinrichtung wird so klein gewählt, dass sie nicht ausreicht, um das Verbindungsstück und das Verbindungsgegenstück auseinander zu drücken, wenn das elektrische Verbindungssystem eingebaut ist. Gegebenenfalls wird dies durch Befestigungselemente in der Nachbarschaft der elektrischen Verbindung gewährleistet.The spring force of the spring device is chosen so small that it is not sufficient to press apart the connector and the connector counterpart when the electrical connection system is installed. Optionally, this is ensured by fasteners in the vicinity of the electrical connection.

Eine besonders einfache und robuste Ausgestaltung sieht vor, dass die bewegliche Lagerung des ersten Kontaktierungshalters in dem erfindungsgemäßen Verbindungsstück derart ausgestaltet ist, dass der Kontaktierungshalter eine translatorische Bewegung ausführen kann. Die bewegliche Lagerung ist erfindungsgemäß so ausgestaltet, dass der wenigstens eine erste Vorsprung bei einer Bewegung des ersten Kontaktierungshalters in Richtung der beweglichen Lagerung hinter einen korrespondierenden zweiten Vorsprung eines korrespondierenden Verbindungsgegenstückes hintergreift. Bei einer Ausführungsform, bei der die bewegliche Lagerung eine translatorische Bewegung bewirkt, schiebt sich der erste Vorsprung in gerader Linie hinter den zweiten Vorsprung.A particularly simple and robust embodiment provides that the movable mounting of the first contacting holder in the inventive Connector is designed such that the contacting holder can perform a translational movement. The movable bearing according to the invention is designed so that the at least one first projection engages behind a corresponding second projection of a corresponding connection counterpart in a movement of the first contacting holder in the direction of the movable bearing. In an embodiment in which the movable support causes a translatory movement, the first projection slides in a straight line behind the second projection.

Bei anderen Ausführungen ist die bewegliche Lagerung zum Beispiel derart ausgestaltet, dass der erste Kontaktierungshalter sich rotatorisch bewegen kann, so dass der wenigstens eine erste Vorsprung des ersten Kontaktierungshalters des Verbindungsstückes und der wenigstens eine zweite Vorsprung des zweiten Kontaktierungshalters des Verbindungsgegenstückes nach Art eines Bajonettverschlusses hintereinander greifen.In other embodiments, the movable mounting is configured, for example, such that the first contacting holder can move in rotation so that the at least one first projection of the first contacting holder of the connecting piece and the at least one second projection of the second contacting holder of the connection counterpart engage one behind the other in the manner of a bayonet closure ,

Für den wenigstens einen elektrischen Kontakt des Verbindungsstückes können verschiedenartige Kontakte vorgesehen sein. Besonders vorteilhaft ist die Verwendung eines FPC-Kontaktes (Flexible Printed Circuit-Kontaktes) eines FPC-Kontaktelementes oder eines Kontaktes eines Flachleiterkontaktelementes (FFC- bzw. Flexible Flat Cable-Kontaktelementes). Solche Kontakte umfassen elektrische Leiterbahnen auf einem flexiblen Substrat und können leicht durch Aufdrücken anderer Kontakte kontaktiert werden. Insbesondere eignen sie sich für ein erfindungsgemäßes Verbindungsstück da, sie eine Verschiebung des Kontaktes mit Bezug zu einem Kontakt eines Verbindungsgegenstückes erlauben.For the at least one electrical contact of the connector various contacts can be provided. Particularly advantageous is the use of an FPC contact (Flexible Printed Circuit Contact) of an FPC contact element or a contact of a flat conductor contact element (FFC or Flexible Flat Cable contact element). Such contacts include electrical traces on a flexible substrate and can be easily contacted by pressing other contacts. In particular, they are suitable for a connector according to the invention because they allow a displacement of the contact with respect to a contact of a connection counterpart.

Für den wenigstens einen elektrischen Kontakt eines erfindungsgemäßen Verbindungsgegenstückes können ebenfalls unterschiedliche Kontaktsysteme verwendet werden. Besonders geeignet ist die Verwendung von Bogenkontakten (bow-terminals), die durch ihre Federspannung einen sicheren Kontakt gewährleisten.For the at least one electrical contact of a connection counterpart of the invention may also be different contact systems be used. Particularly suitable is the use of bow contacts (bow terminals), which ensure a secure contact by their spring tension.

Besonders vorteilhaft wirken Bogenkontakte an dem Verbindungsstück mit FPC-Kontakten oder Flachleiterkontakten an dem Verbindungsstück zusammen. Ebenso vorteilhaft können Bogenkontakte an dem Verbindungsstück und FPC-Kontakte bzw. Flachleiterkontakte an dem Verbindungsgegenstück vorgesehen sein.Particularly advantageous arc contacts act on the connector with FPC contacts or flat conductor contacts on the connector together. Likewise, arc contacts can be provided on the connector and FPC contacts or flat conductor contacts on the connector counterpart.

Besonders vorteilhaft lassen sich das erfindungsgemäße Verbindungsstück, das erfindungsgemäße Verbindungsgegenstück bzw. das erfindungsgemäße elektrische Verbindungssystem im automobilen Bereich einsetzen, wo eine Vielzahl von elektrischen Verbindungen in Abdeckungs- oder Verkleidungselementen notwendig sind, die auch bei Vibrationsbelastung sicher zusammenhalten müssen.Particularly advantageously, the connector according to the invention, the connection counterpart of the invention or the electrical connection system according to the invention can be used in the automotive sector, where a variety of electrical connections in cover or trim elements are necessary, which must hold together safely even with vibration load.

Fig. 1 zeigt ein Verbindungsstück 100. In dem ersten Träger 10 ist eine Ausnehmung 13 vorgesehen, in dem ein erster Kontaktierungshalter 12 in Richtung C verschiebbar gelagert ist. Der erste Kontaktierungshalter weist erste Vorsprünge 14 auf, die sich parallel zu seiner Oberfläche erstrecken und von denen nur zwei exemplarisch mit Bezugsziffern versehen sind. Ein FPC-Kontaktelement (Flexible Printed Circuit-Kontaktelement) 18 erstreckt sich im Wesentlichen parallel zur Oberfläche des ersten Kontaktierungshalters 12. Das Ende des FPC-Kontaktelementes senkt sich in eine Mulde 20 des ersten Kontaktierungshalters 12. Von der Oberfläche des ersten Trägers 10 erstrecken sich Positionierungsbolzen 16 senkrecht weg. Auf der gegenüberliegenden Seite des ersten Trägers 10 befindet sich ein Abschlussstück 11.1 shows a connecting piece 100. A recess 13 is provided in the first carrier 10, in which a first contacting holder 12 is displaceably mounted in the direction C. The first Kontaktierungshalter has first projections 14 which extend parallel to its surface and only two of which are exemplified by reference numerals. An FPC (Flexible Printed Circuit Contact) contact element 18 extends substantially parallel to the surface of the first contacting holder 12. The end of the FPC contact element lowers into a trough 20 of the first contacting holder 12. Extending from the surface of the first carrier 10 Positioning pin 16 vertically away. On the opposite side of the first carrier 10 is a closing piece 11th

In Fig. 2 ist ein korrespondierendes Verbindungsgegenstück 200 gezeigt. Es weist einen zweiten Träger 30 auf, der zum Beispiel ein Metallteil umfasst. Dabei kann es sich zum Beispiel um einen Dachquerträger eines Automobils handeln. An dem zweiten Träger 30 ist ein zweiter Kontaktierungshalter 32 fest montiert. Er weist zweite Vorsprünge 34 auf, die derart angeordnet sind, dass sie in noch zu beschreibender Weise mit den ersten Vorsprüngen 14 des Verbindungsstückes 100 zusammenwirken können.In Fig. 2, a corresponding connection counterpart 200 is shown. It has a second carrier 30, which comprises, for example, a metal part. This may, for example, be a roof cross member of an automobile. On the second carrier 30, a second contacting holder 32 is fixedly mounted. It has second projections 34 which are arranged so that they can interact with the first projections 14 of the connecting piece 100 in a manner to be described later.

Zu dem zweiten Kontaktierungshalter 32 führen elektrische Zuleitungen 38, deren Enden mit Bogenkontakten 40 versehen sind. In dem zweiten Träger 30 befinden sich Positionierungslöcher 36, die in noch zu beschreibender Weise mit den Positionierungsbolzen 16 des Verbindungsstückes 100 zusammenwirken.Lead to the second Kontaktierungshalter 32 electrical leads 38, the ends of which are provided with arc contacts 40. In the second carrier 30 are positioning holes 36, which cooperate in a manner to be described with the positioning pin 16 of the connecting piece 100.

In Fig. 3 sind verschiedene Stadien des Zusammenführens des Verbindungsstückes 100 und des Verbindungsgegenstückes 200 dargestellt. Man erkennt insbesondere Zapfen 22, die an dem ersten Kontaktierungshalter 12 des Verbindungsstückes 100 seitlich vorgesehen sind und die in Führungskanäle 24 eingreifen, die an einer senkrechten Wand des ersten Trägers 10 vorgesehen sind. Die Führungskanäle 24 sind schräg mit Bezug zur Verbindungsrichtung A angeordnet und enden in einem geraden Bereich 26, der sich in Verbindungsrichtung A erstreckt. Der Kontaktierungshalter 12 ist mit Hilfe einer Spiralfeder 28 gegen den Träger 10 vorgespannt, so dass bei entspannter Feder 28 die Zapfen 22 in einer Stellung in den Führungskanälen 24 liegen, die in Teilfigur 3a gezeigt ist. Teilfigur 3b zeigt einen Zustand, in dem das Verbindungsstück 100 bereits an dem Verbindungsgegenstück 200 anliegt. Weitere Bewegung in Verbindungsrichtung A führt in noch zu beschreibender Weise zu einer Bewegung des Kontaktierungshalters 12 in Richtung C und somit zu dem Zustand, der in Teilfigur 3c gezeigt ist.In Fig. 3, various stages of bringing together the connector 100 and the connection counterpart 200 are shown. It can be seen in particular pins 22 which are provided laterally on the first contacting holder 12 of the connecting piece 100 and which engage in guide channels 24 which are provided on a vertical wall of the first carrier 10. The guide channels 24 are arranged obliquely with respect to the connection direction A and terminate in a straight region 26 which extends in the connection direction A. The contacting holder 12 is biased by means of a coil spring 28 against the carrier 10, so that when the spring 28 relaxed, the pins 22 are in a position in the guide channels 24, which is shown in part figure 3a. Part Figure 3b shows a state in which the connector 100 is already applied to the connection counterpart 200. Further movement in the direction of connection A leads in a manner to be described to a movement of the contacting holder 12 in the direction C and thus to the state shown in part 3c.

Fig. 4 zeigt denselben Bewegungsablauf in denselben Stufen, nur im seitlichen Schnitt der einzelnen Komponenten. Besonders gut sind hier die Bogenkontakte 40 des Verbindungsgegenstückes 200 erkennbar, die mit den Kontakten des FPC-Kontaktelementes 18 zusammenwirken. In Fig. 4 ist außerdem die Führung 29 der Feder 28 erkennbar, die zu einer stabilen Lagerung führt.Fig. 4 shows the same movement in the same stages, only in the lateral section of the individual components. Especially good here are the bow contacts 40 of the connection counterpart 200 recognizable, which cooperate with the contacts of the FPC contact element 18. In Fig. 4 also the guide 29 of the spring 28 can be seen, which leads to a stable storage.

Fig. 5 zeigt den Zustand, wie er in Teilfiguren 3b und 4b dargestellt ist, in perspektivischer Darstellung. Der Abstand vom ersten Träger 10 zum zweiten Träger 30 beträgt zum Beispiel 10 mm, wodurch die Führungslänge f festgelegt wird. Die gesamte Anordnung befindet sich zum Beispiel an der Rückseite einer Verkleidung eines Kraftfahrzeuges, zum Beispiel hinter einem Dachhimmel. Die Einbauhöhe e ergibt sich aus der Summe der Höhe des ersten Trägers 10 und des Abschlussstückes 11 zum Beispiel zu etwa 25 mm.Fig. 5 shows the state, as shown in sub-figures 3b and 4b, in perspective view. The distance from the first carrier 10 to the second carrier 30 is, for example, 10 mm, whereby the guide length f is set. The entire arrangement is, for example, at the rear of a panel of a motor vehicle, for example behind a headliner. The installation height e results from the sum of the height of the first carrier 10 and the end piece 11, for example, to about 25 mm.

Fig. 6 zeigt die Kontaktgeometrie. Das FPC-Kontaktelement 18 weist bei der dargestellten Ausgestaltung mehrere elektrische Leiterbahnen 19 auf. Im Bereich 21 ist das FPC-Kontaktelement 18 in dargestellter Weise parallel gegenüber dem Bereich 17 versetzt. Das FPC-Kontaktelement 18 befindet sich bei der beschriebenen Ausführungsform in dem ersten Kontaktierungshalter 12 des Verbindungsstückes 100. Der abgesenkte Bereich 21 des FPC-Kontaktelementes 18 ist in der Mulde 20 des ersten Kontaktierungshalters 12 des Verbindungsstückes 100 angeordnet. Das Verbindungsgegenstück 200 weist Bogenkontakte 40 auf, die mit Kabeln 38 in elektrischer Verbindung stehen. Wird das FPC-Kontaktelement 18 mit dem ersten Kontaktierungshalter 12 in Richtung C verschoben, stößt die Stufe zwischen den Bereichen 21 und 17 an den Bogenkontakt 40, so dass der Bogenkontakt 40 auf den Bereich 17 aufgeschoben wird und einen elektrischen Kontakt zu einer der Kontaktbahnen 19 herstellt.Fig. 6 shows the contact geometry. In the illustrated embodiment, the FPC contact element 18 has a plurality of electrical conductor tracks 19. In the region 21, the FPC contact element 18 is offset parallel to the region 17 in the manner illustrated. In the described embodiment, the FPC contact element 18 is located in the first contacting holder 12 of the connecting piece 100. The lowered region 21 of the FPC contact element 18 is arranged in the depression 20 of the first contacting holder 12 of the connecting piece 100. The connection counterpart 200 has bow contacts 40, which are in electrical connection with cables 38. If the FPC contact element 18 is displaced in the direction C with the first contacting holder 12, the step between the regions 21 and 17 abuts the arc contact 40, so that the arc contact 40 is pushed onto the region 17 and makes electrical contact with one of the contact paths 19 manufactures.

Die beschriebene Ausführungsform eines erfindungsgemäßen elektrischen Verbindungssystems mit einem erfindungsgemäßen Verbindungsstück 100 und einem erfindungsgemäßen Verbindungsgegenstück 200 wird wie folgt verwendet.The described embodiment of an electrical connection system according to the invention comprising a connecting piece 100 according to the invention and a connecting counterpart 200 according to the invention is used as follows.

Zunächst werden das Verbindungsgegenstück 100 und das Verbindungsgegenstück 200 in eine Position gebracht, in der sie sich gegenüberliegen, wie es in Teilfiguren 3a bzw. 4a gezeigt ist. Weitere Bewegung des Verbindungsstückes 100 in Verbindungsrichtung A führt dazu, dass die Positionierungsbolzen 16 in korrespondierende Positionierungsöffnungen 36 eingreifen, wie es in Teilfiguren 3b bzw. 4b erkennbar ist. Die ersten Vorsprünge 14 des ersten Kontaktierungshalters 10 und die zweiten Vorsprünge 34 des zweiten Kontaktierungshalters 30 sind derart lateral versetzt zueinander angeordnet, dass sich bei diesem Verschiebungsprozess , Vorsprünge des einen Elementes und Zwischenräume zwischen den Vorsprüngen des anderen Elementes gegenüberstehen.First, the connection counterpart 100 and the connection counterpart 200 are brought into a position in which they face each other, as shown in sub-figures 3a and 4a, respectively. Further movement of the connecting piece 100 in the connecting direction A causes the positioning bolts 16 to engage in corresponding positioning openings 36, as can be seen in subfigures 3b and 4b. The first projections 14 of the first contacting holder 10 and the second projections 34 of the second contacting holder 30 are arranged laterally offset from one another such that, in this displacement process, projections of the one element and spaces between the projections of the other element face each other.

Durch die Vorspannung der Feder 28 ist gewährleistet, dass der erste Kontaktierungshalter 12 in optimaler Position ist, wobei die Zapfen 22 an den Enden der Führungskanäle 24 anschlagen. Diese optimale Position ist so gewählt, dass sich beim Einführen der Positionierungsbolzen 16 in die Positionierungsöffnungen 36 die ersten Vorsprünge 14 des ersten Kontaktierungshalters und die zweiten Vorsprünge 34 des zweiten Kontaktierungshalters nicht behindern.By the bias of the spring 28 ensures that the first Kontaktierungshalter 12 is in an optimal position, the pins 22 abut at the ends of the guide channels 24. This optimum position is chosen so that upon insertion of the positioning pins 16 into the positioning holes 36, the first projections 14 of the first contacting holder and the second projections 34 of the second contacting holder do not interfere.

Weitere Verschiebung des ersten Trägers 10 des Verbindungsstückes 100 in Verbindungsrichtung A kann jetzt nur noch in der Verbindungsrichtung A erfolgen, da die Positionierungsöffnungen 36 die Positionierungsbolzen 16 führen.Further displacement of the first carrier 10 of the connecting piece 100 in the connecting direction A can now only take place in the connecting direction A, since the positioning openings 36 guide the positioning bolts 16.

Der erste Kontaktierungshalter 12 schlägt an dem zweiten Träger 30 des Verbindungsgegenstückes 200 an, wobei die zweiten Vorsprünge 34 des zweiten Kontaktierungshalters 32 des Verbindungsgegenstückes 200 durch die Abstände zwischen den ersten Vorsprüngen 14 des ersten Kontaktierungshalters 12 des Verbindungsstückes 100 hindurchtreten. Wie es insbesondere in Teilfigur 4b erkennbar ist, liegen die Enden der Bogenkontakte 40 dann in der Mulde 20 des ersten Kontaktierungshalters 12, in der der abgesenkte Bereich 21 des FPC-Kontaktelementes 18 liegt.The first contacting holder 12 abuts on the second carrier 30 of the connecting counterpart 200, wherein the second protrusions 34 of the second contacting holder 32 of the connecting counterpart 200 pass through the spaces between the first protrusions 14 of the first contacting holder 12 of the connecting piece 100. As it can be seen in particular in part figure 4b, the ends of the sheet contacts 40 are then in the trough 20 of the first Kontaktierungshalters 12, in which the lowered portion 21 of the FPC contact element 18 is located.

Weitere Bewegung des ersten Trägers 10 in Verbindungsrichtung A ist ausgehend von der Stellung der Teilfiguren 3b bzw. 4b nur noch möglich, wenn der erste Kontaktierungshalter 12 sich gegen die Federspannung der Feder 28 in den Träger 10 hineinbewegt. Dabei führen die Zapfen 22 den ersten Kontaktierungshalter 12 entlang der schrägen Ausrichtung der Führungskanäle 24 und führen so zu einer lateralen Versetzung des ersten Kontaktierungshalters 12 in Richtung C. Dabei schieben sich die ersten Vorsprünge 14 des ersten Kontaktierungshalters 12 hinter die zweiten Vorsprünge 34 des zweiten Kontaktierungshalters 32 des Verbindungsgegenstückes 200 und führen so zu einer festen Verbindung des ersten Kontaktierungshalters 12 und des zweiten Kontaktierungshalters 32. Gleichzeitig schiebt sich der erhöhte Bereich 17 des FPC-Kontaktelementes 18 unter die Bogenkontakte 40 des Verbindungsgegenstückes 200, so dass eine elektrische Verbindung zwischen einzelnen Bogenkontakten 40 und den Leiterbahnen 19 auf dem FPC-Kontaktelement 18 gewährleistet ist. Die Federspannung der Bogenkontakte 40 bewirkt einen sicheren Kontakt.Further movement of the first carrier 10 in the connecting direction A is based on the position of the subfigures 3b and 4b only possible if the first contacting holder 12 moves against the spring tension of the spring 28 in the carrier 10. The pins 22 guide the first contacting holder 12 along the oblique orientation of the guide channels 24 and thus lead to a lateral displacement of the first Kontaktierungshalters 12 in the direction C. Here, the first projections 14 of the first Kontaktierungshalters 12 push behind the second projections 34 of the second Kontaktierungshalters At the same time, the raised portion 17 of the FPC contact element 18 pushes under the arc contacts 40 of the connection counterpart 200 so that an electrical connection between individual arcuate contacts 40th and the conductor tracks 19 is ensured on the FPC contact element 18. The spring tension of the sheet contacts 40 causes a secure contact.

Es entsteht der Zustand, wie er in Teilfiguren 3c bzw. 4c gezeigt ist. Der erste Träger 10 und der zweite Träger 30 können jetzt zum Beispiel durch zusätzliche Befestigungselemente aneinander fixiert werden. In der Regel ist es jedoch ausreichend, wenn zum Beispiel der Dachhimmel eines Kraftfahrzeuges an dem Abschlussstück 11 anliegt, da die Federkraft der Feder 28 so gering gewählt wird, dass ein Abrutschen des ersten Trägers 10 von dem zweiten Träger 30 durch die Spannung des Dachhimmels verhindert wird.The result is the state as shown in subfigures 3c and 4c, respectively. The first carrier 10 and the second carrier 30 can now be fixed to each other, for example, by additional fastening elements. In general, however, it is sufficient if, for example, the headliner of a motor vehicle rests against the end piece 11, since the spring force of the spring 28 is chosen so small that slipping of the first support 10 from the second support 30 is prevented by the tension of the headliner becomes.

In der Verkupplungsstellung, die in Teilfigur 3c dargestellt ist, ist eine laterale Verschiebung des ersten Kontaktierungshalters 12 nicht mehr möglich, die zum Beispiel durch gegenseitige Bewegungen des FPC-Kontaktelementes 18 und der Kabel 38 hervorgerufen werden würde, die vibrationsbedingt auftreten können.In the coupling position illustrated in FIG. 3c, a lateral displacement of the first contacting holder 12 is no longer possible, which would be caused, for example, by mutual movements of the FPC contact element 18 and the cables 38, which may occur due to vibration.

Das erfindungsgemäße Verbindungsstück, das erfindungsgemäße Verbindungsgegenstück bzw. das erfindungsgemäße elektrische Verbindungssystem stellen eine flexible elektrische Kupplung zur Verfügung, die sogar einen blinden bzw. automatischen Steckvorgang ermöglicht. Der Montageprozess ist dadurch erheblich vereinfacht und kann automatisiert werden. Die Anzahl der Montageschritte und die Anzahl der Komponenten ist stark reduziert. Insbesondere eignen sich die erfindungsgemäßen Ausführungsformen zur Verwendung von Flachleiterkontakten oder FPC-Kontakten, die zunehmend im automobilen Bereich Einsatz finden.The connecting piece according to the invention, the counterpart connection according to the invention and the electrical connection system according to the invention provide a flexible electrical coupling which even enables a blind or automatic plugging operation. The assembly process is thereby considerably simplified and can be automated. The number of assembly steps and the number of components is greatly reduced. In particular, the embodiments of the invention are suitable for use of flat conductor contacts or FPC contacts, which are increasingly used in the automotive sector.

Durch entsprechende Auswahl der Anzahl der elektrischen Kontakte kann mit nur einem Verbindungssystem eine Vielzahl von elektrischen Kontakten parallel hergestellt werden.By appropriate selection of the number of electrical contacts, a plurality of electrical contacts can be made in parallel with only one connection system.

Die Verbindung ist einfach durchzuführen und durch entsprechend ausgestaltete Positionierungselemente, zum Beispiel durch konisch zulaufende Positionierungsbolzen 16, ohne aufwändige Vorjustage möglich.The connection is easy to perform and by appropriately designed positioning elements, for example by tapered positioning pin 16, without costly Vorjustage possible.
