Description

Die vorliegende Erfindung betrifft ein Steckverbindungssystem beziehungsweise eine Steckverbindungsvorrichtung mit einer integrierten Verriegelung zur elektrischen Verbindung von elektrischen Modulen beispielsweise von Installationsgeräten oder Schaltgeräten. Bei solchen Steckverbindungssystemen müssen in der Regel eine Vielzahl von elektrischen Verbindungen zwischen den Modulen hergestellt werden. Dies erfolgt üblicherweise durch mehradrige Verbindungskabel, die an ihren Enden mit mehrpoligen Steckern ausgestattet sind, welche in entsprechende Buchsen an den Modulen eingesteckt werden.The present invention relates to a plug connection system or a plug connection device with an integrated lock for the electrical connection of electrical modules, for example, installation devices or switching devices. In such connector systems usually a variety of electrical connections between the modules must be made. This is usually done by multi-core connection cable, which are equipped at their ends with multipolar connectors, which are plugged into corresponding sockets on the modules.

Dabei ist es erforderlich, dass die Steckverbindung auf ebenso schnelle wie einfache Weise hergestellt werden kann und eine zuverlässige elektrische Verbindung zwischen den Modulen entsteht. Es besteht ferner die Notwendigkeit, die Steckverbindungen zuverlässig zu verriegeln, damit sie mechanischen Belastungen, wie z.B. Schwingungen und Schockbelastungen standhält und dabei die elektrische Verbindung zwischen den Modulen erhalten und voll funktionsfähig bleibt.It is necessary that the connector can be made in a fast as well as simple manner and a reliable electrical connection between the modules. There is also a need to reliably lock the connectors so that they can withstand mechanical stresses, e.g. Withstand vibrations and shock loads while maintaining the electrical connection between the modules and remaining fully functional.

Es sind bereits Steckverbindungssysteme mit Verriegelungsvorrichtungen zur Verbindung von elektrischen Modulen bekannt, die aus einem Stecker und einer komplementär zu dem Stecker ausgebildeten Buchse bestehen, die in der Verriegelungsposition mit mechanischen Hilfsmitteln miteinander verbunden werden. Bei einem derartigen, bekannten Steckverbindungssystem wird der Stecker mit Hilfe von Schrauben mit der Buchse verbunden, wobei am Stecker eine oder mehrere Schrauben drehbar gelagert sind und an der Buchse Gewinde befestigt sind. In der Verriegelungsposition, d.h. wenn der Stecker in die Buchse eingesteckt ist, werden die Schrauben am Stecker in die Gewinde an der Buchse eingeschraubt und so eine feste Verbindung zwischen Stecker und Buchse erzeugt.There are already known connector systems with locking devices for connecting electrical modules, which consist of a plug and a complementary formed to the connector socket, which are connected to each other in the locking position with mechanical aids. In such a known connector system, the plug is connected by means of screws to the socket, wherein one or more screws are rotatably mounted on the plug and are secured to the socket thread. In the locking position, ie when the plug is inserted into the socket, the screws are screwed to the plug into the threads on the socket and so creates a firm connection between the plug and socket.

Zur Trennung der Verbindung zwischen Stecker und Buchse müssen die Schrauben wieder aus den Gewinden ausgeschraubt werden. Dieses Steckverbindungssystem hat deshalb den Nachteil, dass die Herstellung und die Lösung der Steckverbindung mehrerer Handgriffe bedarf und sowohl für die Unterbringung der Schraubverbindung als auch für deren Bedienung einen hohen Platzbedarf mit sich bringt.To separate the connection between the plug and socket, the screws must be unscrewed from the threads again. This connector system therefore has the disadvantage that the production and the solution of the connector requires several handles and brings both for the accommodation of the screw as well as their operation a lot of space.

Bei einem weiteren Steckverbindungssystem mit einer Verriegelungsvorrichtung nach dem Stand der Technik sind am Stecker Kipphebel angeordnet, die in der Verriegelungsposition an der Buchse angreifen und so eine mechanische Kopplung zwischen dem Stecker und der Buchse herstellen. Dabei sind die Kipphebel am Stecker unter einer Vorspannung federnd gelagert, so dass sie in der Verriegelungsposition in entsprechende Vorsprünge beziehungsweise Vertiefungen an der Buchse einschnappen.In a further connector system with a locking device according to the prior art, tilting levers are arranged on the plug, which engage in the locking position on the socket and thus produce a mechanical coupling between the plug and the socket. The rocker arms are spring-mounted on the plug under a bias, so that they snap into the locking position in corresponding projections or depressions on the socket.

Zur Trennung der Verbindung zwischen Stecker und Buchse müssen bei diesem Steckverbindungssystem die Kipphebel einzeln und manuell in eine Entriegelungsposition gebracht werden, bei der sie aus den Vorsprüngen beziehungsweise Vertiefungen an der Buchse ausgreifen, um eine Trennung des Steckers von der Buchse zu ermöglichen. Dieses Steckverbindungssystem hat deshalb ebenfalls den Nachteil, dass die Lösung der Steckverbindung verhältnismäßig aufwändig ist und die Anordnung der Kipphebel am Stecker sowie deren Bedienung einen hohen Platzbedarf erfordern.To separate the connection between the plug and socket, the rocker arms must be individually and manually brought into an unlocking in this connector system, in which they reach out of the projections or recesses on the socket to allow separation of the plug from the socket. Therefore, this connector system also has the disadvantage that the solution of the connector is relatively expensive and require the arrangement of the rocker arm on the plug and their operation a lot of space.

Die Verriegelungseinrichtung ist dabei zwischen einer Verriegelungsposition und einer Entriegelungsposition bewegbar. Des Weiteren ist die Verriegelungseinrichtung mit dem Gehäuse einteilig verbunden.A known plug connection device, which is plugged for electrical connection in electrical modules to a mating connector device, is made of US 5,328,288 known. The plug connection device described therein comprises a housing and a locking device connected to the housing, which is designed for mechanical coupling of the plug connection device with the mating plug connection device.

Die Aufgabe der vorliegenden Erfindung besteht somit darin, eine Steckverbindungsvorrichtung und ein Steckverbindungssystem für elektrische Module mit möglichst geringen Kosten bereitzustellen, die/das sich durch eine einfache Handhabung sowie geringen Platzbedarf auszeichnet und eine zuverlässige elektrische Verbindung der Module gewährleistet. Ferner soll ein entsprechendes Verfahren zum Lösen des Steckverbindungssystems angegeben werden.The object of the present invention is therefore to provide a connector device and a connector system for electrical modules with the lowest possible cost, which is characterized by ease of use and small footprint and ensures a reliable electrical connection of the modules. Furthermore, a corresponding method for releasing the connector system is to be specified.

Erfindungsgemäß wird die Aufgabe gelöst durch eine Steckverbindungsvorrichtung, die zur elektrischen Verbindung von elektrischen Modulen in/an eine Gegensteckverbindungsvorrichtung steckbar ist, mit einem Gehäuse und mindestens einer mit dem Gehäuse verbundenen Verriegelungseinrichtung zur mechanischen Kopplung der Steckverbindungsvorrichtung mit der Gegensteckverbindungsvorrichtung, die Verriegelungseinrichtung zwischen einer Verriegelungsposition und einer Entriegelungsposition bewegbar ist, wobei die Verriegelungseinrichtung mit dem Gehäuse einteilig verbunden ist und die Verriegelungseinrichtung ein Entriegelungselement aufweist, das in der Entriegelungsposition in einen komplementär zu dem Entriegelungselement ausgebildetes Gegenelement an dem Gehäuse eingreift, so dass die Verriegelungseinrichtung in der Entriegelungsposition fixierbar ist.According to the invention the object is achieved by a plug connection device which is plugged for the electrical connection of electrical modules in / on a mating connector device, with a housing and at least one locking device connected to the housing for the mechanical coupling of the connector device with the mating connector device, the locking device between a locking position and an unlocking position is movable, wherein the locking device is integrally connected to the housing and the locking device comprises an unlocking element which in the unlocked position in a complementary to the unlocking element formed counter element engages the housing, so that the locking device is fixable in the unlocking position.

Der Vorteil dieser Einteiligkeit der Verriegelungseinrichtung mit dem Gehäuse besteht in der vereinfachten Produktion des Gesamtsystems sowie in der vereinfachten Logistik bei der Handhabung der zu montierenden Teile für das Verbindungssystem. Außerdem wird der Montageaufwand vermindert.The advantage of this one-piece design of the locking device with the housing is the simplified production of the overall system as well as the simplified logistics in the handling of the parts to be assembled for the connection system. In addition, the assembly cost is reduced.

Darüber hinaus ist erfindungsgemäß vorgesehen ein Verfahren zum Trennen einer obigen Steckverbindungsvorrichtung von der Gegensteckverbindungsvorrichtung durch Fixieren der mindestens einen Verriegelungseinrichtung in der Entriegelungsposition mittels der Entriegelungseinrichtung und Lösen der Steckverbindungsvorrichtung von der Gegensteckverbindungsvorrichtung.In addition, the invention provides a method for separating an above connector device of the mating connector device by fixing the at least one locking device in the unlocked position by means of the unlocking device and releasing the connector device of the mating connector device.

Bei einer bevorzugten Ausführungsform der erfindungsgemäßen Steckverbindungsvorrichtung weist die Verriegelungseinrichtung mindestens einen Entriegelungshaken oder ein entsprechendes Entriegelungselement auf. Der/das kann in einer Entriegelungsposition in ein(en) komplementär zu dem Entriegelungshaken ausgebildeten Widerhaken beziehungsweise Gegenelement an dem Gehäuse der Steckverbindungsvorrichtung eingreifen. Der Entriegelungshaken befindet sich vorzugsweise am freien Ende des Verriegelungshakens, kann aber auch an einer anderen Stelle des Verriegelungshakens mit einem Abstand von seinem festen Ende angeordnet sein. Um die Steckverbindungsvorrichtung von der Gegensteckverbindungsvorrichtung zu lösen, d.h. beispielsweise den Stecker aus der Buchse zu entnehmen, wird der Verriegelungshaken aus der Verriegelungsposition in die Entriegelungsposition gebracht, wobei der Verriegelungshaken aus dem Eingriff in den Stecker gelöst wird, indem der Entriegelungshaken mit dem Widerhaken an der Buchse in Eingriff gebracht wird. Auf diese Weise wird der Verriegelungshaken in der Entriegelungsposition gehalten, solange der Stecker aus der Buchse entnommen wird beziehungsweise entfernt ist.In a preferred embodiment of the plug connection device according to the invention, the locking device has at least one unlocking hook or a corresponding unlocking element. The / can engage in a unlocking position in a (s) complementary to the unlocking hook formed barb or counter-element on the housing of the connector device. The unlocking hook is preferably located at the free end of the locking hook, but can also be on a be arranged at a different location of the locking hook with a distance from its fixed end. To release the connector device of the mating connector device, ie, for example, to remove the plug from the socket, the locking hook is brought from the locking position to the unlocked position, wherein the locking hook is released from the engagement in the plug by the unlocking hook with the barb on the Bush is engaged. In this way, the locking hook is held in the unlocked position, as long as the plug is removed from the socket or is removed.

Durch die Integration eines Verriegelungshakens als Verriegelungseinrichtung in eine Buchse der Steckverbindung wird einerseits der Platzbedarf der Verriegelungseinrichtung auf ein Minimum reduziert und andererseits die Handhabung des Steckverbindungssystems insgesamt vereinfacht, wobei eine zuverlässige elektrische Verbindung der Module gewährleistet bleibt. Das Steckverbindungssystem nach der vorliegenden Erfindung hat ferner den Vorteil, dass in diesem Fall an den Steckern der Verbindungskabel keine Verriegelungshaken mehr erforderlich sind, so dass die Verbindungskabel und die Stecker für Beschädigungen weniger anfällig sind. Aus dem gleichen Grund können zum einen die Stecker der Verbindungskabel auf kleinerem Raum auf den Modulen untergebracht werden und zum anderen wird der Platzbedarf für die Handhabung bei der Platzierung der Stecker auf den Modulen beziehungsweise bei der Entfernung der Stecker von den Modulen verringert. Darüber hinaus ist das erfindungsgemäße Steckverbindungssystem aufgrund der einfachen Lösung kostengünstig herzustellen.By integrating a locking hook as a locking device in a socket of the connector on the one hand, the space requirement of the locking device is reduced to a minimum and on the other hand simplifies the handling of the connector system as a whole, with a reliable electrical connection of the modules is guaranteed. The connector system according to the present invention also has the advantage that in this case no more locking hooks are required on the connectors of the connecting cable, so that the connecting cable and the connector for damage are less prone. For the same reason, on the one hand the connectors of the connection cables can be accommodated in a smaller space on the modules and on the other hand, the space for handling in the placement of the plug on the modules or in the removal of the connector is reduced by the modules. In addition, the connector system according to the invention is inexpensive to manufacture due to the simple solution.

Durch das erfindungsgemäße Steckverbindungssystem können zwei oder mehrere elektrische Module miteinander verbunden werden. Die Verbindung der Module erfolgt jeweils über ein mehrpoliges Verbindungskabel (z.B. 10-polig), das typischerweise in verschiedenen Längen angeboten wird. Dadurch können sich die Module unmittelbar nebeneinander oder in einem Abstand von beispielsweise bis zu 200 cm befinden. An den Enden der Verbindungskabel befindet sich jeweils ein Stecker, während die Gegenstücke zu den Steckern - also die Buchsen - in den Modulen untergebracht sind.By means of the plug connection system according to the invention, two or more electrical modules can be connected to one another. The modules are connected via a multi-pole connection cable (eg 10-pin), which is typically offered in different lengths. This allows the Modules are located next to each other or at a distance of, for example, up to 200 cm. At the ends of the connecting cable is in each case a plug, while the counterpart to the plugs - so the sockets - are housed in the modules.

Bei einer bevorzugten Ausführungsform des Steckverbindungssystems nach der vorliegenden Erfindung weist der Verriegelungshaken ein festes Ende auf, das vorzugsweise am Boden der Buchse angeordnet ist. Alternativ kann das feste Ende des Verriegelungshackens auch an einer anderen Stelle der Buchse angeordnet sein. Der Verriegelungshaken ist aus einem flexiblen Material vorzugsweise Kunststoff gefertigt und über sein festes Ende derart an der Buchse angeordnet, dass er aufgrund seiner Flexibilität federnde Eigenschaften besitzt.In a preferred embodiment of the connector system according to the present invention, the locking hook has a fixed end, which is preferably arranged at the bottom of the socket.

The locking hook is made of a flexible material, preferably plastic and arranged on its fixed end to the socket so that it has resilient properties due to its flexibility.

Ferner weist der Verriegelungshaken ein freies Ende auf, das die mechanische Kopplung zwischen Stecker und Buchse herstellt. Dies geschieht, indem das freie Ende des Verriegelungshakens am Stecker angreift, sobald sich der Stecker in der Verriegelungsposition befindet, d.h. vollständig in die Buchse eingeführt ist. Dabei ist es besonders vorteilhaft, wenn das freie Ende des Verriegelungshakens einen Vorsprung aufweist, der in der Verriegelungsposition in eine komplementär zu dem Vorsprung ausgebildete Vertiefung im Stecker eingreift. Der Vorsprung im Verriegelungshaken wirkt mit der im Stecker ausgebildeten Vertiefung folglich derart zusammen, dass der Stecker zuverlässig in der Verriegelungsposition gehalten wird.Furthermore, the locking hook has a free end, which establishes the mechanical coupling between plug and socket. This is done by engaging the free end of the locking hook on the plug once the plug is in the lock position, i. completely inserted into the socket. It is particularly advantageous if the free end of the locking hook has a projection which engages in the locking position in a complementary formed to the projection recess in the plug. The protrusion in the locking hook thus cooperates with the depression formed in the plug such that the plug is reliably held in the locking position.

Besonders vorteilhaft ist es, wenn der Eingriff zwischen dem Entriegelungshaken des Verriegelungshakens und dem Widerhaken an der Buchse so gestaltet ist, dass der Entriegelungshaken beim Einschieben des Steckers in die Buchse selbständig aus dem Widerhaken ausrastet. Auf diese Weise wird die Verriegelung zwischen dem Stecker und der Buchse allein durch das Einschieben des Steckers in die Buchse hergestellt, sobald der Stecker die Verriegelungsposition erreicht hat, ohne dass dazu ein weiterer Handgriff oder eine zusätzliche Betätigung des oder der Verriegelungshaken erforderlich ist.It when the engagement between the unlocking hook of the locking hook and the barb on the socket is designed so that the release hook disengages automatically when inserting the plug into the socket from the barb. In this way, the lock between the plug and the socket is made solely by the insertion of the plug into the socket as soon as the plug has reached the locking position without the need for another handle or additional operation of the locking hook or is required.

Zusätzlich kann der Verriegelungshaken an der Buchse derart federnd gelagert sein, dass er aufgrund seiner Flexibilität in die Richtung seiner Verriegelungsposition hin vorgespannt ist, so dass der Verriegelungshaken beim Einschieben des Steckers in die Buchse selbständig in die Verriegelungsposition schnappt.In addition, the locking hook can be resiliently mounted on the sleeve so that it is biased in the direction of its locking position due to its flexibility, so that the locking hook snaps into the locking position automatically upon insertion of the plug into the socket.

Die Einführungsbewegung des Steckers in die Buchse kann weiter erleichtert werden, wenn der Verriegelungshaken an seinem freien Ende eine Flanke aufweist, die im Wesentlichen in Richtung der Einführungsbewegung des Steckers in die Buchse abgeschrägt ist. Dabei ist es besonders vorteilhaft, wenn die Flanke unmittelbar an den Vorsprung angrenzt, der in der Verriegelungsposition am Stecker angreift. Bei der Einführungsbewegung des Steckers in die Buchse kann der Stecker an der Flanke am freien Ende des Verriegelungshackens abgleiten und dabei den Verriegelungshaken in Richtung der Entriegelungsposition drücken. Sobald der Stecker soweit in die Buchse eingeführt ist, dass er die Verriegelungsposition erreicht hat, kann der Verriegelungshaken zurückschnappen und den Stecker in der Verriegelungsposition fixieren.The insertion movement of the plug into the socket can be further facilitated if the locking hook has at its free end a flank which is chamfered substantially in the direction of insertion movement of the plug into the socket. It is particularly advantageous if the edge directly adjacent to the projection, which engages in the locking position on the plug. During the insertion movement of the plug into the socket, the plug can slide on the flank at the free end of the locking hook while pressing the locking hook in the direction of the unlocking position. Once the plug is inserted into the socket so far that he has reached the locking position, the locking hook can snap back and fix the plug in the locked position.

Die erfindungemäße Steckverbindungsvorrichtung kann besonders zuverlässig gestaltet werden, wenn auf zwei gegenüberliegenden Seiten des Gehäuses jeweils eine Verriegelungseinrichtung vorgesehen ist, die in der Verriegelungsposition am Stecker beziehungsweise der Gegensteckverbindungsvorrichtung angreifen. Dadurch wird eine stabile mechanische Kopplung zwischen Stecker und Buchse an zwei gegenüberliegenden Seiten hergestellt.The erfindungemäße plug connection device can be made particularly reliable when a locking device is provided on two opposite sides of the housing, which engage in the locking position on the plug or the mating connector device. As a result, a stable mechanical coupling between the plug and socket is made on two opposite sides.

Das nachfolgend näher beschriebene Ausführungsbeispiel stellt eine bevorzugte Ausführungsform der vorliegenden Erfindung dar.The embodiment described in more detail below represents a preferred embodiment of the present invention.

Um die Funktionsweise des erfindungsgemäßen Steckverbindungssystems besser verstehen zu können, werden zunächst anhand der Figuren 1 bis 3 Steckverbindungssysteme nach dem Stand der Technik näher erläutert.In order to better understand the operation of the connector system according to the invention, are first based on the FIGS. 1 to 3 Connector systems according to the prior art explained in more detail.

In FIG 1 ist eine sogenannte D-SUB-Buchse 5 zur elektrischen Verbindung elektrischer Module gemäß dem Stand der Technik dargestellt. Diese Buchse 5 umfasst ein Gegenstück 1, auf das ein komplementär ausgebildeter Stecker (nicht dargestellt) einer Verbindungsleitung aufgesteckt werden kann. Das Gegenstück 1 weist mehrere Polverbindungen 4 auf, die in entsprechende Leitungen 2 an der Unterseite der Buchse münden, die zu einem elektrischen Modul (nicht dargestellt) führen. Bei diesem bekannten Steckverbindungssystem wird der Stecker mit Hilfe von Schraubverbindungen fixiert. An der Buchse 5 sind Gewinde 3 befestigt, in die am Stecker drehbar gelagerte Schrauben (nicht dargestellt) eingeschraubt werden können. Wenn der Stecker in die Buchse 5 eingesteckt ist, werden die Schrauben am Stecker in die Gewinde 3 an der Buchse eingeschraubt und so eine feste Verbindung zwischen Stecker und Buchse 5 erzeugt.In FIG. 1 is a so-called D-SUB socket 5 for the electrical connection of electrical modules according to the prior art shown. This socket 5 comprises a counterpart 1, on which a complementary formed plug (not shown) of a connecting line can be plugged. The counterpart 1 has a plurality of pole connections 4, which open into corresponding lines 2 at the bottom of the socket, which lead to an electrical module (not shown). In this known connector system, the connector is fixed by means of screw. At the socket 5 are Fixed thread 3, in the rotatably mounted on the plug screws (not shown) can be screwed. When the plug is inserted into the socket 5, the screws are screwed to the plug in the thread 3 on the socket, thus creating a firm connection between the plug and socket 5.

Zur Trennung der Verbindung zwischen Stecker und Buchse 5 müssen die Schrauben wieder aus den Gewinden 3 ausgeschraubt werden. Dieses Steckverbindungssystem hat deshalb den Nachteil, dass die Herstellung und die Lösung der Steckverbindung mehrerer Handgriffe bedarf und sowohl für die Unterbringung der Schraubverbindung als auch für deren Bedienung einen hohen Platzbedarf mit sich bringt.To separate the connection between the plug and socket 5, the screws must be unscrewed from the threads 3 again. This connector system therefore has the disadvantage that the production and the solution of the connector requires several handles and brings both for the accommodation of the screw as well as their operation a lot of space.

In FIG 2 ist ein 2,54 mm-Raster-Stecker 6 einer Verbindungsleitung zur elektrischen Verbindung elektrischer Module gemäß dem Stand der Technik dargestellt. Bei diesem Steckverbindungssystem wird der Stecker 6 in der Buchse (nicht dargestellt) verrastet. Dazu sind am Stecker 6 Kipphebel 7 angeordnet, die mit einem Haken 10 in der Verriegelungsposition an der Buchse 8 angreifen und so eine mechanische Kopplung zwischen dem Stecker 6 und der Buchse 8 herstellen. Dabei sind die Kipphebel 7 am Stecker 6 derart federnd gelagert, dass sie zwischen einer Verriegelungsposition und einer Entriegelungsposition geschwenkt werden können. Die Kipphebel 7 sind mit einer Vorspannung beaufschlagt, so dass sie in Richtung der Verriegelungsposition vorgespannt sind. Es ist deutlich zu erkennen, dass die Kipphebel 7 den vertikal höchsten Punkt des Steckers darstellen und somit den Raumbedarf von elektrischen Modulen, die mit derartigen Steckern verbunden sind, erhöhen.In FIG. 2 a 2.54 mm raster plug 6 of a connecting line for the electrical connection of electrical modules according to the prior art is shown. In this connector system, the plug 6 is locked in the socket (not shown). For this purpose, 6 rocker arms 7 are arranged on the plug, which engage with a hook 10 in the locking position on the socket 8 and so produce a mechanical coupling between the plug 6 and the socket 8. The rocker arms 7 are resiliently mounted on the plug 6 such that they can be pivoted between a locking position and an unlocking position. The rocker arms 7 are subjected to a bias so that they are biased in the direction of the locking position. It can be clearly seen that the rocker arms 7 represent the vertically highest point of the plug and thus increase the space requirement of electrical modules that are connected to such plugs.

In FIG 3 ist eine Detailansicht des in FIG2 gezeigten 2,54 mm-Raster-Steckers 6 zur elektrischen Verbindung elektrischer Module gemäß dem Stand der Technik dargestellt. In FIG 3 ist zu erkennen, dass der Kipphebel 7 am Stecker 6 in der Verriegelungsposition mit seinem Haken 10 in eine entsprechende Hintergreifung 9 an der Buchse 8 einschnappt, sobald der Stecker 6 bis zur Verriegelungsposition in die Buchse 8 eingeführt ist.In FIG. 3 is a detailed view of the in fig2 shown 2.54 mm raster plug 6 for electrical connection of electrical modules according to the prior art shown. In FIG. 3 It can be seen that the rocker arm 7 on the plug 6 in the locking position with its hook 10 snaps into a corresponding rear engagement 9 on the socket 8, as soon as the plug 6 is inserted to the locking position in the socket 8.

Zur Trennung der Verbindung zwischen Stecker 6 und Buchse 8 müssen bei diesem Steckverbindungssystem die Kipphebel 7 einzeln und manuell in die Entriegelungsposition gebracht werden, bei der die Haken 10 aus den Hintergreifungen 9 an der Buchse 8 ausgreifen, um eine Trennung des Steckers 6 von der Buchse 8 zu ermöglichen. Dieses Steckverbindungssystem hat deshalb ebenfalls den Nachteil, dass die Lösung der Steckverbindung mit mehreren Handgriffen verbunden ist und die Anordnung der Kipphebel 7 am Stecker 6 sowie deren Bedienung einen hohen Platzbedarf erfordern. Außerdem ist der Kipphebel 7 als separates Teil ausgestaltet, das an das Steckverbindungssystem angebracht werden muss. In nachteiliger Weise ist somit ein zusätzliches Teil erforderlich, das es einzusparen gilt.To separate the connection between the plug 6 and socket 8, the rocker arms 7 must be individually and manually brought into the unlocking in this connector system, in which the hooks 10 from the Hintergreifungen 9 on the socket 8 reach to a separation of the plug 6 of the socket 8 to allow. Therefore, this connector system also has the disadvantage that the solution of the connector is connected with multiple handles and the arrangement of the rocker arm 7 on the connector 6 and their operation require a lot of space. In addition, the rocker arm 7 is designed as a separate part that must be attached to the connector system. Disadvantageously, therefore, an additional part is required, which is to be saved.

In FIG 4 ist ein Modulpaket 12 dargestellt, das mehrere elektrische Module 13 umfasst. Die Module 13 sind über Verbindungsleitungen 14 elektrisch miteinander verbunden. Die aus Flachbandleitungen bestehenden Verbindungsleitungen 14 sind an ihren Enden jeweils mit Steckern versehen, die in entsprechende Buchsen in den Modulen 13 eingesteckt sind. Die Verbindung zwischen dem Verbindungskabel und dem Modul wird mit Hilfe des Steckverbindungssystems mit Entriegelungselementen gemäß der vorliegenden Erfindung verbessert.In FIG. 4 a module package 12 is shown that includes a plurality of electrical modules 13. The modules 13 are electrically connected to each other via connecting lines 14. The existing of flat ribbon cables connecting lines 14 are provided at their ends with plugs that are plugged into corresponding sockets in the modules 13. The connection between the connection cable and the module is improved by means of the connector system with unlocking elements according to the present invention.

FIG 5 zeigt eine schematische Darstellung einer bevorzugten Ausführungsform der Steckverbindungsvorrichtung mit Entriegelungselementen gemäß der vorliegenden Erfindung. In FIG 6 ist eine perspektivische Darstellung eines Deckels der in FIG 5 gezeigten bevorzugten Ausführungsform der Steckverbindungsvorrichtung gemäß der vorliegenden Erfindung dargestellt. Für die nachfolgend beschriebene Ausführungsform wird eine bekannte Steckverbindung im 2,54 mm-Raster als Basis gewählt, aber es können auch andere Standard-Systeme für die Verwirklichung der vorliegenden Erfindung gewählt werden. FIG. 5 shows a schematic representation of a preferred embodiment of the connector device with unlocking according to the present invention. In FIG. 6 is a perspective view of a lid of in FIG. 5 shown preferred embodiment of the connector device according to the present invention. For the embodiment described below, a known connector in 2.54 mm grid is chosen as the basis, however, other standard systems may be chosen for the practice of the present invention.

In FIG 5 zeigt die erfindungsgemäße Steckverbindungsvorrichtung in der Verriegelungsposition. Ein nicht dargestellter Standardstecker kann in ein zum Stecker komplementär ausgebildetes Gehäuse 16 der Steckverbindungsvorrichtung vollständig eingeführt werden. Die erfindungsgemäße Steckverbindungsvorrichtung umfasst in der dargestellten Ausführungsform zwei Verriegelungshaken 17 zur mechanischen Kopplung des Steckers mit dem Gehäuse 16, wobei die Verriegelungshaken 17 in das Gehäuse 16 integriert sind. Die Verriegelungshaken 17 sind auf zwei gegenüberliegenden Seiten des Gehäuses 16 angeordnet.In FIG. 5 shows the plug connection device according to the invention in the locking position. An unillustrated standard connector can be completely inserted into a plug-shaped housing 16 of the connector device. The plug connection device according to the invention comprises in the illustrated embodiment, two locking hooks 17 for the mechanical coupling of the plug with the housing 16, wherein the locking hooks 17 are integrated into the housing 16. The locking hooks 17 are arranged on two opposite sides of the housing 16.

Sowohl das Gehäuse 16 als auch die Verriegelungshaken 17 sind aus einem flexiblen Material vorzugsweise Kunststoff gefertigt. Die Verriegelungshaken 17 weisen ein festes Ende 22 auf, das jeweils am Boden 23 des Gehäuses 16 der Buchse angeordnet ist, wobei die Verriegelungshaken 17 aufgrund ihrer Flexibilität federnd gelagert sind. Dabei sind die Verriegelungshaken 17 mit einer Vorspannung beaufschlagt, so dass sie in die Richtung ihrer Verriegelungsposition vorgespannt sind.Both the housing 16 and the locking hooks 17 are made of a flexible material, preferably plastic. The locking hooks 17 have a fixed end 22, which is arranged in each case at the bottom 23 of the housing 16 of the bush, wherein the locking hooks 17 are resiliently mounted due to their flexibility. In this case, the locking hooks 17 are biased so that they are biased in the direction of their locking position.

Ferner weisen die Verriegelungshaken 17 jeweils ein freies Ende auf, an dem ein nach innen ragender Vorsprung 18 ausgebildet ist. Durch den Vorsprung 18 am freien Ende der Verriegelungshaken 17 wird eine mechanische Kopplung zwischen dem Stecker und der Buchse 16 hergestellt, indem der Vorsprung 18 in eine entsprechende Vertiefung beziehungsweise Hintergreifung am Stecker eingreift, sobald der Stecker vollständig in die Buchse beziehungsweise deren Gehäuse 16 in Richtung des Pfeils A eingeführt ist und sich damit in der Verriegelungsposition befindet. Auf diese Weise wird der Stecker zuverlässig in seiner Verriegelungsposition gehalten.Furthermore, the locking hooks 17 each have a free end, on which an inwardly projecting projection 18 is formed. By the projection 18 at the free end of the locking hook 17, a mechanical coupling between the plug and the socket 16 is made by the projection 18 engages in a corresponding recess or Hintergreifung on the plug as soon as the plug completely into the socket or the housing 16 in the direction of the arrow A is inserted and thus is in the locking position. In this way, the plug is reliably held in its locking position.

Die Verriegelungshaken 17 sind jeweils an ihrem freien Ende zusätzlich mit einer Flanke 20 versehen, die eine in Richtung der Einführungsbewegung A des Steckers in die Buchse beziehungsweise das Gehäuse 16 abgeschrägte Rundung 20 aufweisen, wobei die Flanke 20 unmittelbar an den Vorsprung 18 angrenzt, der in der Verriegelungsposition am Stecker angreift. Dadurch kann der Stecker während der Einführungsbewegung in Richtung des Pfeils A in die Buchse 16 an der Flanke 20 am freien Ende der Verriegelungshaken 17 abgleiten und dabei die Verriegelungshaken 17 nach außen drücken. Sobald der Stecker vollständig in die Buchse 16 eingeführt ist und die Verriegelungsposition erreicht hat, schnappt der Verriegelungshaken 17 aufgrund seiner Vorspannung zurück und fixiert den Stecker in der Verriegelungsposition.The locking hooks 17 are each provided at their free end additionally with a flank 20 which have a beveled in the direction of the insertion movement A of the plug into the socket or the housing 16 rounding 20, wherein the flank 20 directly adjacent to the projection 18 which in the locking position engages the plug. As a result, during the insertion movement in the direction of the arrow A, the plug can slide into the socket 16 on the flank 20 at the free end of the locking hook 17, thereby pressing the locking hooks 17 outwards. Once the plug is fully inserted into the socket 16 and has reached the locking position, the locking hook 17 snaps back due to its bias and fixes the plug in the locked position.

Darüber hinaus weisen die Verriegelungshaken 17 an ihrem freien Ende jeweils einen Entriegelungshaken 19 auf, der in einer Entriegelungsposition in einen komplementär zu dem Entriegelungshaken ausgebildeten Widerhaken 21 an dem Gehäuse 16 angreift. Um den Stecker aus dem Gehäuse 16 zu entnehmen, werden die Verriegelungshaken 17 aus der Verriegelungsposition in die Entriegelungsposition gebracht, indem die Verriegelungshaken 17 nach außen gedrückt werden. Dabei werden einerseits die Vorsprünge 18 der Verriegelungshaken 17 aus dem Eingriff mit den Hintergreifungen am Stecker gelöst und andererseits die Entriegelungshaken 19 soweit über die Widerhaken 21 an dem Gehäuse 16 geschoben bis diese miteinander in Eingriff kommen. Auf diese Weise wird die mechanische Kopplung zwischen dem Stecker und der Buchse beziehungsweise dem Gehäuse 16 gelöst und der Stecker kann aus der Buchse 16 entnommen werden. Die Verriegelungshaken 17 werden durch den Eingriff zwischen den Entriegelungshaken 19 und den Widerhaken 21 an der Buchse 16 in der Entriegelungsposition gehalten.In addition, the locking hooks 17 each have an unlocking hook 19 at its free end, which engages in an unlocking position in a complementary to the unlocking hook barbs 21 on the housing 16. To remove the plug from the housing 16, the locking hooks 17 are brought from the locking position to the unlocked position by the locking hooks 17 are pressed outwards. In this case, on the one hand, the projections 18 of the locking hooks 17 are disengaged from the engagement with the back grips on the plug and on the other hand, the release hooks 19 pushed over the barbs 21 on the housing 16 until they come into engagement with each other. In this way, the mechanical coupling between the plug and the socket or the housing 16 is released and the plug can be removed from the socket 16. The locking hooks 17 are held by the engagement between the unlocking hooks 19 and the barbs 21 on the sleeve 16 in the unlocked position.

Zur Lösung des Eingriffs zwischen den Entriegelungshaken 19 an den freien Enden der Verriegelungshaken 17 und den Widerhaken 21 an dem Gehäuse 16 werden die Entriegelungshaken 19 wieder über die Widerhaken 21 zurück geschoben. Besonders vorteilhaft ist es jedoch, wenn der Eingriff zwischen dem Entriegelungshaken 19 des Verriegelungshackens 17 und dem Widerhaken 21 an der Buchse 16 sich beim Einschieben des Steckers in die Buchse 16 selbständig löst, indem beispielsweise beim Eindrücken des Steckers die Widerhaken 21, die entsprechend beweglich zu gestalten sind (in den Figuren nicht dargestellt), nach unten bewegt werden.To solve the engagement between the unlocking hooks 19 at the free ends of the locking hooks 17 and the barbs 21 on the housing 16, the release hooks 19 are pushed back over the barbs 21. It is particularly advantageous, however, if the engagement between the unlocking hook 19 of the locking hook 17 and the barb 21 on the socket 16 solves independently upon insertion of the plug into the socket 16, for example, by pressing the plug, the barbs 21, the correspondingly movable are shaped (not shown in the figures), are moved down.
