Description

Die Erfindung betrifft eine Steckverbinderanordnung, aufweisend einen Steckverbinder und einen damit zusammensteckbaren Gegensteckverbinder, gemäß den Merkmalen des Oberbegriffes des Patentanspruches 1.The invention relates to a connector assembly, comprising a connector and a mating connector mating therewith, according to the features of the preamble of claim 1.

Steckverbinderanordnungen, die einen Steckverbinder und einen damit zusammensteckbaren Gegensteckverbinder umfassen, sind für Anwendungen in der Automobiltechnik, insbesondere für Personenkraftwagen, bekannt. Mit dieser Steckverbinderanordnung werden Signale oder Spannungsversorgungen übertragen, wobei von den Herstellern der Fahrzeuge die Größe, die Form (insbesondere das Steckgesicht) sowie die Anzahl der Kontaktpartner des Streckverbinders und des zugehörigen Gegensteckverbinders zwingend vorgeschrieben werden. Dabei ist weiterhin von besonderer Bedeutung, dass solche Steckverbinderanordnungen nur einen vorgegebenen, im Regelfall sehr kleinen Bauraum ausfüllen dürfen. Neben diesen Anforderungen besteht als weitere Anforderung, dass der Steckverbinder und der damit zusammensteckbare Gegensteckverbinder möglichst ohne Kraftaufwand und dabei zuverlässig zusammengesteckt werden muss. Um die zusammengesteckte Steckverbinderanordnung dauerhaft zusammenzuhalten, ist es bekannt, dass die beiden zusammengesteckten Steckverbinder mittels Rastverbindungen gesichert werden. Diese Rastverbindungen sind bekannt und wirken auf Dauer zuverlässig, wobei jedoch zu berücksichtigen ist, dass für den Rastvorgang eine bestimmte Kraft beim Zusammenstecken aufzubringen ist. Darüber hinaus ist es erforderlich, beim Zusammenstecken eine bestimmte Kraft aufzuwenden, damit der Kontaktpartner des Steckverbinders mit dem Kontaktpartner des Gegensteckverbinders in Wirkverbindung zwecks elektrischer Kontaktierung gebracht werden kann. Um auch hier auf Dauer eine zuverlässige elektrische Kontaktierung sicherstellen zu können, ist es erforderlich, dass der Kontaktpartner des Steckverbinders und der Kontaktpartner des zugehörigen Gegensteckverbinders aufeinander abgestimmt sind (z. B. Kontaktstift und Kontaktbuchse), wobei beim Zusammenstecken eine Mindestkraft aufgebracht werden muss, um z. B. den Kontaktstift zur Überwindung der Reibung in die Kontaktbuchse einstecken zu können. In Summe sind daher verhältnismäßig hohe Kräfte aufzubringen, was jedoch bei der vorgegebenen Größe der Steckverbinder und der damit zusammensteckbaren Gegensteckverbinder insbesondere ohne Werkzeug nicht ohne Weiteres möglich ist. Da die Miniaturisierung solcher Steckverbinderanordnungen in der Fahrzeugtechnik immer weiter voranschreitet und die Montage, d. h. das Zusammenstecken von Steckverbinder und Gegensteckverbinder, möglichst einfach und ohne Werkzeug realisiert werden soll, sind die bisher bekannten Lösungen unzufriedenstellend.Connector assemblies comprising a connector and a mating connector mating therewith are known for automotive applications, particularly passenger cars. With this connector assembly signals or power supplies are transmitted, whereby the manufacturers of the vehicles, the size, the shape (in particular the mating face) and the number of contact partners of the draw connector and the associated mating connector are mandatory. It is also of particular importance that such connector assemblies may only fill a given, usually very small space. In addition to these requirements, there is a further requirement that the connector and the plug-together mating connector must be plugged together as possible without effort and thereby reliable. In order to permanently hold the plugged connector assembly together, it is known that the two mated connectors are secured by snap-in connections. These snap-in connections are known and work reliably in the long term, but it should be noted that for the latching process a certain force is applied when mating. In addition, it is necessary to spend a certain force when mating, so that the contact partner of the connector with the contact partner of the Mating connector can be brought into operative connection for the purpose of making electrical contact. In order to be able to ensure a reliable electrical contacting in the long term, it is necessary for the contact partner of the connector and the contact partner of the associated mating connector to be matched to one another (eg contact pin and contact socket), whereby a minimum force must be applied during mating, to z. B. to plug the contact pin to overcome the friction in the contact socket. In sum, therefore, relatively high forces are applied, but this is not readily possible with the given size of the connector and the mating connector plugged together in particular without tools. Since the miniaturization of such connector assemblies in the automotive industry continues to progress and the assembly, ie the mating of connectors and mating connectors, as simple and without tools to be implemented, the previously known solutions are unsatisfactory.

Eine Steckverbinder anordnung gemäss den Merkmalen des Oberbegriffes des Patentanspruches 1 ist aus DE-A-102005062889 bekannt.A connector assembly according to the features of the preamble of claim 1 is made DE-A-102005062889 known.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Steckverbinderanordnung, aufweisend einen Steckverbinder und einen damit zusammensteckbaren Gegensteckverbinder, für die Automobiltechnik bereitzustellen, mit der die Steckverbinderanordnung weiter miniaturisiert werden kann, d. h. wenig Bauraum einnimmt, wobei die Kräfte beim Zusammenstecken von Steckverbinder und Gegensteckverbinder weiter reduziert werden sollen, ohne dass die Kontaktsicherheit sich verschlechtert. Insbesondere soll die Kontaktsicherheit sogar für den Dauereinsatz noch erhöht werden, wobei gleichzeitig auch sichergestellt sein muss, dass eine einfache Montage gegeben ist und der Steckverbinder und der Gegensteckverbinder dauerhaft zusammengesteckt bleiben.The invention is therefore an object of the invention to provide a connector assembly comprising a connector and a mating connector mating therewith, for the automotive industry, with which the connector assembly can be further miniaturized, d. H. takes up little space, the forces when mating connectors and mating connectors should be further reduced without the contact reliability deteriorates. In particular, the contact reliability should be increased even for continuous use, while at the same time it must be ensured that a simple assembly is given and the connector and the mating connector remain stuck together.

Diese Aufgabe ist durch die Merkmale des Patentanspruches 1 gelöst. Ausgehend von einer Steckverbinderanordnung, aufweisend einem Steckverbinder und einen damit zusammensteckbaren Gegensteckverbinder, wobei der Steckverbinder sowie der Gegensteckverbinder jeweils zumindest zwei Kontaktpartner aufweisen und die Kontaktpartner des Steckverbinders und des Gegensteckverbinders elektrisch miteinander kontaktiert werden und in einem zugehörigen Steckverbindergehäuse bzw. Gegensteckverbindergehäuse angeordnet sind, ist erfindungsgemäß vorgesehen, dass die Kontaktpartner des Steckverbinders in jeweils einer Kontaktkammer eines Kontaktpartnergehäuses angeordnet sind, wobei das Kontaktpartnergehäuse in dem Steckverbindergehäuse, das relativ zu dem Kontaktpartnergehäuse bewegbar ist, angeordnet ist und das Steckverbindergehäuse eine in Richtung des Gegensteckverbinders weisende und in das Gegensteckverbindergehäuse hineinreichende und sich über die Kontaktpartner des Steckverbinders erstreckende und im zusammengesteckten Zustand auf die Kontaktpartner wirkende Lasche aufweist.This object is solved by the features of claim 1. Starting from a connector assembly comprising a Connector and a mating connector mating therewith, wherein the connector and the mating connector each have at least two contact partners and the contact partners of the connector and the mating connector are electrically contacted and arranged in an associated connector housing or mating connector housing, the invention provides that the contact partner of the connector are arranged in each case a contact chamber of a contact partner housing, wherein the contact partner housing in the connector housing which is movable relative to the contact partner housing, and the connector housing facing in the direction of the mating connector and extending into the mating connector housing and extending over the contact partners of the connector and in the has mated state on the contact partner acting tab.

Das Vorhandensein von zumindest zwei oder auch mehr Kontaktpartnern jeweils in dem Steckverbinder und in dem Gegensteckverbinder trägt dem Umstand Rechnung, dass die erforderlichen Signale bzw. eine Spannungsversorgung über die Steckverbinderanordnung übertragen werden kann.The presence of at least two or more contact partners respectively in the connector and in the mating connector takes into account the fact that the required signals or a voltage supply can be transmitted via the connector assembly.

Der Gegensteckverbinder ist dazu ausgebildet, dass er die erforderliche Anzahl von Kontaktpartnern aufnimmt, wobei in besonders vorteilhafter Weise vorgesehen ist, dass jeweils ein Kontaktpartner in einer zugehörigen Kontaktkammer in dem Gegensteckverbindergehäuse angeordnet ist.The mating connector is adapted to receive the required number of contact partners, wherein it is provided in a particularly advantageous manner that in each case a contact partner is arranged in an associated contact chamber in the mating connector housing.

Der Gegensteckverbinder weist ein Kontaktpartnergehäuse sowie ein Steckverbindergehäuse auf, die beide als separate Bestandteile des Steckverbinders ausgebildet sind. Dabei nimmt das Kontaktpartnergehäuse in erforderlicher Anzahl und Anordnung die Kontaktpartner des Steckverbinders auf, wobei diese beispielsweise mittels einer Rastverbindung in ihrer Kontaktkammer festgelegt werden. Über dem Kontaktpartnergehäuse ist das Steckverbindergehäuse 4 bewegbar dazu angeordnet, wobei es besonders vorteilhaft ist, dass das Kontaktpartnergehäuse und das Steckverbindergehäuse relativ zwischen zwei Endstellungen rastend relativ zueinander bewegbar und ausgebildet sind. Das bedeutet, dass die beiden genannten Gehäuse zunächst separat voneinander hergestellt werden (z. B. in einem Kunststoffspritzgussverfahren) und derart ausgestaltet sind, dass das Steckverbindergehäuse über das Kontaktpartnergehäuse insbesondere linear verschoben (alternativ verdreht) werden kann, wobei z. B. Rastmittel oder dergleichen vorhanden sind, die bewirken, dass das Steckverbindergehäuse zunächst in einer ersten Stellung relativ zu dem Kontaktpartnergehäuse angeordnet ist und unter Kraftaufbringung durch Verschieben (oder Verdrehen) von dieser ersten Endstellung in eine weitere Stellung, insbesondere eine weitere Endstellung, gebracht werden kann. Diese Anordnung und Funktionsweise ist wichtig für die im Folgenden noch zu beschreibende weitere Anordnung und Funktionsweise zur Lösung der gestellten Aufgabe.The mating connector has a contact partner housing and a connector housing, which are both formed as separate components of the connector. In this case, the contact partner housing takes in required number and arrangement, the contact partner of the connector on, which are determined for example by means of a latching connection in their contact chamber. About the contact partner housing, the connector housing 4 is movably arranged thereto, wherein it is particularly advantageous that the contact partner housing and the connector housing are relatively movable and formed relative to each other between two end positions latching. This means that the two mentioned housings are initially produced separately from each other (eg in a plastic injection molding process) and are configured in such a way that the connector housing can in particular be linearly displaced (alternatively rotated) via the contact partner housing, wherein z. B. latching means or the like are present, which cause the connector housing is first arranged in a first position relative to the contact partner housing and force application by shifting (or twisting) from this first end position to another position, in particular a further end position, brought can. This arrangement and mode of operation is important for the further arrangement and mode of operation to be described below for solving the problem set out below.

Um die Kräfte beim Zusammenstecken zu minimieren, ist weiterhin vorgesehen, dass das Steckverbindergehäuse eine in das Gegensteckverbindergehäuse hineinreichende und sich über die Kontaktpartner des Steckverbinders erstreckende Lasche aufweist. Diese Lasche liegt noch nicht oder ohne Einwirkung auf bzw. an den Kontaktpartnern des Steckverbinders an, wenn sich das Steckverbindergehäuse in seiner ersten Endstellung (Vorverraststellung) befindet. Dadurch und die entsprechende Gestaltung des Kontaktpartners des Steckverbinders wird bewirkt, dass der Steckverbinder in den Gegensteckverbinder eingesteckt werden kann, wobei gleichzeitig mit dem Einstecken auch der Kontaktpartner des Gegensteckverbinders in den Kontaktpartner des Steckverbinders eingesteckt wird. Dies ist beispielsweise dadurch realisiert, dass der Kontaktpartner des Steckverbinders als Kontaktbuchse ausgebildet ist, die einen Querschnitt aufweist, der gleich oder vorzugsweise geringfügig größer ist als der als Kontaktstift ausgebildete Kontaktpartner des Gegensteckverbinders. Dies bewirkt, dass der Steckverbinder und der Gegensteckverbinder und insbesondere die beiden zugehörigen Kontaktpartner ohne Kraftaufwand zwecke elektrischer Kontaktierung miteinander in Verbindung gebracht werden können. Bei diesem Zusammensteckvorgang sind somit nur geringfügige Kräfte aufzubringen, nämlich um das Steckgesicht des Steckverbinders in das Steckgesicht des Gegensteckverbinders einzuführen. Erst wenn sich das Kontaktpartnergehäuse mit seiner vorstehenden Lasche nahezu vollständig unter Berücksichtigung eines noch zu beschreibenden Freiraumes in dem Gegensteckverbinder befindet, wird das Steckverbindergehäuse relativ zu dem Kontaktpartnergehäuse von der ersten Endstellung in die zweite Endstellung bewegt (insbesondere verschoben), wodurch zum einen bewirkt wird, dass der Steckverbinder und der Gegensteckverbinder rastend zueinander festgelegt werden und zum anderen bewirkt wird, dass die Lasche unter Abstützung an dem Gegensteckverbindergehäuse ausgelenkt wird und auf die Kontaktpartner des Steckverbinders und auch auf die Kontaktpartner des Gegensteckverbinders wirkt, um eine ausreichend hohe Kontaktkraft (Normalkraft) aufzubringen. Um diese Kontaktkraft aufzubringen, kann zwecks Montage sowohl das Steckverbindergehäuse als auch das Gegensteckverbindergehäuse von einem Monteur in die Hand genommen werden, um das Steckverbindergehäuse relativ zu dem schon im Gegensteckverbindergehäuse sich befindenden Kontaktpartnergehäuse zu verschieben und Steckverbinder und Gegensteckverbinder einerseits mechanisch zu verrasten und andererseits die Kontaktierung sicherzustellen. Aufgrund der Geometrien, insbesondere der abstehenden und in das Gegensteckverbindergehäuse hineinreichenden Lasche des Steckverbindergehäuses wird in vorteilhafter Weise die Hebelwirkung ausgenutzt, um die erforderlichen Kontaktkräfte, d. h. die Andruckkräfte des Kontaktpartners des Steckverbinders an den zugehörigen Kontaktpartner des Gegensteckverbinders, aufzubringen.In order to minimize the forces during mating, it is further provided that the connector housing has a extending into the mating connector housing and extending over the contact partner of the connector tab. This tab is not or without action on or at the contact partners of the connector, when the connector housing is in its first end position (Vorverraststellung). This and the corresponding design of the contact partner of the connector causes the connector can be inserted into the mating connector, wherein at the same time with the insertion of the contact partner of the mating connector is inserted into the contact partner of the connector. This is realized, for example, in that the Contact partner of the connector is designed as a contact socket, which has a cross section which is equal to or preferably slightly larger than the contact pin designed as a contact partner of the mating connector. This causes the connector and the mating connector and in particular the two associated contact partners without any effort purposes electrical contacting can be associated with each other. In this mating operation thus only minor forces are applied, namely to introduce the mating face of the connector in the mating face of the mating connector. Only when the contact partner housing with its protruding tab is almost completely in consideration of a clearance to be described in the mating connector, the connector housing is moved relative to the contact partner housing from the first end position to the second end position (in particular shifted), which is effected on the one hand that the connector and the mating connector are fixed detent to each other and on the other causes the tab is deflected under support on the mating connector housing and acts on the contact partners of the connector and also on the contact partner of the mating connector to apply a sufficiently high contact force (normal force) , To apply this contact force, both the connector housing and the mating connector housing can be taken by a fitter in order to move the connector housing relative to the already in the mating connector housing located contact partner housing and connectors and mating connectors on the one hand to lock mechanically and on the other hand, the contact sure. Due to the geometries, in particular the protruding and extending into the mating connector housing tab of the connector housing, the lever effect is advantageously utilized to the required contact forces, ie the pressure forces of Contact partner of the connector to the associated contact partner of the mating connector to apply.

Dadurch wird in vorteilhafter Weise durch die Erfindung realisiert, dass hohe Kontaktkräfte und die daraus resultierende elektrische Kontaktsicherheit sowie die erforderliche Verrastung über die Lebensdauer der Steckverbinderanordnung auch bei solchen Steckverbinderanordnungen realisiert werden kann, bei denen von den Fahrzeugherstellern eine Miniaturisierung und vor allen Dingen auch eine vorgegebene Steckgeometrie und ein vorgegebener Bauraum vorgeschrieben sind.This is realized in an advantageous manner by the invention that high contact forces and the resulting electrical contact safety and the required locking over the life of the connector assembly can also be realized in such connector assemblies in which of the vehicle manufacturers a miniaturization and above all, a predetermined Plug geometry and a given space are prescribed.

Im Folgenden wird die Erfindung anhand der Figuren erläutert.The invention will be explained below with reference to the figures.

Die Figuren 1 (in Schnittdarstellung) und 2 (in dreidimensionaler Ansicht) zeigen, soweit im Einzelnen dargestellt, eine Steckverbinderanordnung, die einen Steckverbinder 1 und einen Gegensteckverbinder 2 aufweisen. Der Steckverbinder 1 und der Gegensteckverbinder 2 befinden sich zunächst im nicht zusammengesteckten Zustand, wobei in Figur 1 dargestellt ist, dass der Gegensteckverbinder 2 in einer ersten Stellung schon mit dem Steckverbinder 1 zusammengebracht ist (Figur 1, linke Seite) und der Steckverbinder 1 mit dem Gegensteckverbinder 2 komplett zu der erforderlichen Steckverbinderanordnung zusammengesteckt ist (Figur 1, rechte Darstellung). Dabei ist der Steckverbinder 1 in den Figuren 1 analog zu den Darstellungen in Figur 2 dargestellt, nämlich einmal in einer Vorverrast- und einmal in einer Endverraststellung.The FIGS. 1 (In sectional view) and 2 (in three-dimensional view), as far as shown in detail, a connector assembly having a connector 1 and a mating connector 2. The connector 1 and the mating connector 2 are initially in the unmated state, wherein in FIG. 1 is shown that the mating connector 2 is already brought together in a first position with the connector 1 ( FIG. 1 , left side) and the connector 1 with the mating connector 2 is completely assembled to the required connector assembly ( FIG. 1 , right representation). In this case, the connector 1 in the FIGS. 1 analogous to the illustrations in FIG. 2 shown, namely once in a Vorverrast- and once in a Endverraststellung.

Der Steckverbinder 1 weist ein Kontaktpartnergehäuse 3 und ein relativ dazu bewegbares, insbesondere verschiebbares Steckverbindergehäuse 4 auf. In dem Steckverbinder 1 sind in nicht näher bezeichneten Kontaktkammern des Kontaktpartnergehäuses 3 zumindest zwei oder mehr Kontaktpartner 5, hier ausgebildet als Buchsenkontakt, angeordnet und z. B. mittels Rastverbindungen in ihrer Lage fixiert. Analog dazu weist der Gegensteckverbinder 2 ebenfalls in Kontaktkammern oder in anderer Weise befestigte Kontaktpartner 6 auf, wobei die Kontaktpartner 6 in einem Gegensteckverbindergehäuse 7 angeordnet sind. Bei dem Gegensteckverbinder 2 sind die Kontaktpartner 6 beispielsweise als Kontaktstifte ausgebildet. Die Kontaktpartner 5, 6 sind in an sich bekannter Weise am Ende von elektrischen Leitungen, umfassend einen elektrischen Leiter und einen Mantel, angeordnet. Hierbei kommt es nicht darauf an, ob es sich um Rundleitungen, Flachleitungen oder andere Bauformen von Leitungen handelt.The connector 1 has a contact partner housing 3 and a relatively movable, in particular displaceable connector housing 4. In the connector 1, at least two or more contact partners 5, designed here as a female contact, are arranged in unspecified contact chambers of the contact partner housing 3 and z. B. by means Locking connections fixed in position. Similarly, the mating connector 2 also in contact chambers or otherwise attached contact partners 6, wherein the contact partners 6 are arranged in a mating connector housing 7. In the mating connector 2, the contact partners 6 are formed, for example, as contact pins. The contact partners 5, 6 are arranged in a manner known per se at the end of electrical lines, comprising an electrical conductor and a jacket. It does not matter whether it is round cables, flat cables or other types of cables.

Das Kontaktpartnergehäuse und das Steckverbindergehäuse, die beide beispielsweise in einem Kunststoffspritzgussverfahren hergestellt werden, sind derart gestaltet und vormontiert, dass sich das Kontaktpartnergehäuse 3 in einer ersten Stellung, insbesondere einer Endstellung, auf dem Steckverbindergehäuse 4 befindet. Dieser Zustand ist in Figur 1, links, dargestellt. Dabei ist erkennbar, dass das Steckverbindergehäuse 4 im vormontierten Zustand eine in das Gegensteckverbindergehäuse 7 hineinreichende und sich über die Kontaktpartner 5 des Steckverbinders 1 erstreckende Lasche 8 aufweist. In diesem Zustand liegt die Lasche 8 entweder gar nicht oder mit nur geringer Krafteinwirkung auf die Kontaktpartner 5 an diesen an. Daraus folgt, dass der beispielsweise als Kontaktstift ausgebildete Kontaktpartner 6 des Gegensteckverbinders 2 ohne Kraftaufwand in den als Buchsenkontakt ausgebildeten Kontaktpartner 5 des Steckverbinders 1 eingeführt werden kann. Bei sind noch keine Kontaktkräfte aufzubringen, wobei auch die erforderliche Kontaktsicherheit noch nicht hergestellt ist. Erst wenn das Steckverbindergehäuse 4 von seiner in Figur 1, links, dargestellten ersten Stellung in eine zweite Stellung bewegt wird, die in Figur 1, rechts, gezeigt ist, bewirkt diese Bewegung, dass die Lasche 8 auf die zugehörigen Kontaktpartner 4 des Steckverbinders 1 einwirkt und die erforderliche Kontaktkraft aufbringt. Das bedeutet, dass der als Buchsenkontakt ausgebildete Kontaktpartner 5 des Steckverbinders 1 unter Aufbringung der geschilderten Kontaktkraft dauerhaft und unter Druck an den als Kontaktstift ausgebildeten Kontaktpartner 6 des Gegensteckverbinders 2 zur Anlage kommt, woraus die erforderlichen Kontaktkräfte und die gewünschte Kontaktsicherheit resultieren. Nachdem das Steckverbindergehäuse 4 von seiner ersten Stellung in seine zweite Stellung über das Kontaktpartnergehäuse 3 bewegt worden ist, sind nicht nur die erforderlichen Kontaktkräfte (Normalkräfte) auf die Kontaktpartner aufgebracht worden, sondern es sind auch der Steckverbinder 1 und der Gegensteckverbinder 2 mechanisch miteinander verriegelt, insbesondere verrastet worden, sodass diese dauerhaft zusammengesteckt bleiben, vorzugsweise aber durch entsprechende Kraftaufbringung, die im Normalbetrieb nicht auftritt, wieder voneinander getrennt werden können.The contact partner housing and the connector housing, which are both produced, for example, in a plastic injection molding process, are designed and preassembled such that the contact partner housing 3 is in a first position, in particular an end position, on the connector housing 4. This condition is in FIG. 1 , left, shown. It can be seen that the connector housing 4 in the preassembled state has a extending into the mating connector housing 7 and extending over the contact 5 of the connector 1 tab 8. In this state, the tab 8 is either not at all or with only a small force on the contact partner 5 to this. It follows that the example formed as a contact pin contact partner 6 of the mating connector 2 can be inserted without force in the trained as a female contact partner 5 of the connector 1. At no contact forces are yet to apply, with the required contact security is not yet made. Only when the connector housing 4 of his in FIG. 1 , left, shown first position is moved to a second position, which in FIG. 1 , Right, this movement causes the tab 8 acts on the associated contact partner 4 of the connector 1 and applies the required contact force. That means that as a socket contact trained contact 5 of the connector 1 under application of the described contact force permanently and under pressure to the contact pin 6 formed as a contact partner 6 of the mating connector 2 comes to rest, resulting in the required contact forces and the desired contact reliability. After the connector housing 4 has been moved from its first position to its second position via the contact partner housing 3, not only the required contact forces (normal forces) have been applied to the contact partners, but it is also the connector 1 and the mating connector 2 mechanically interlocked, in particular have been locked so that they remain permanently plugged together, but preferably by appropriate application of force, which does not occur in normal operation, can be separated from each other again.

Die Bezugsziffern 9 und 10 bezeichnen Dichtungen, die zwischen dem Steckverbinder 1 und dem Gegensteckverbinder 2 eine Längswasserdichtheit realisieren, wobei die Dichtung 9 an dem Gegensteckverbinder 2 angeordnet ist und auf dem Kontaktpartner 5 des Steckverbinders 1 wirkt und die Dichtung 10 zwischen dem Steckverbindergehäuse 4 und dem Kontaktpartnergehäuse 3 (oder alternativ auf den Außenmantel des Kabels) dichtet.The reference numerals 9 and 10 denote seals that realize a longitudinal watertightness between the connector 1 and the mating connector 2, wherein the seal 9 is disposed on the mating connector 2 and acts on the contact partner 5 of the connector 1 and the seal 10 between the connector housing 4 and the Contact partner housing 3 (or alternatively on the outer jacket of the cable) seals.

Die schon vorstehend beschriebenen Bewegungsabläufe und die daraus resultierende Funktion ist in Figur 2 noch einmal alleine für den Steckverbinder 1 dargestellt, wobei jedoch zwingend zur Realisierung der Aufbringung der erforderlichen Kontaktkräfte der Gegensteckverbinder 2 vorhanden sein muss, da sich die erfindungsgemäße Lasche 8 des Steckverbinders 1 zur Aufbringung der Kontaktkräfte an dem Gegensteckverbinder 2 abstützen muss.The motion sequences already described above and the resulting function is in FIG. 2 once again shown alone for the connector 1, but it is imperative to realize the application of the required contact forces of the mating connector 2 must be present as the tab 8 of the connector 1 according to the invention for supporting the contact forces on the mating connector 2 must be supported.

In Figur 2 ist in der linken Darstellung die erste Endstellung dargestellt, bei der sich das Kontaktpartnergehäuse in einer ersten Position zu dem Steckverbindergehäuse 4 befindet. Nachdem der somit vorbereitete Steckverbinder 1 in den in Figur 2 nicht dargestellten Gegensteckverbinder 2 eingesetzt worden ist, wird das Steckverbindergehäuse 4 relativ zu dem Kontaktpartnergehäuse 3 verschoben, sodass die Lasche 8 auf die Kontaktpartner des Steckverbinders 1 einwirken kann, um die erforderlichen Kontaktkräfte aufzubringen.In FIG. 2 is shown in the left illustration, the first end position, in which the contact partner housing is in a first position to the connector housing 4. After the thus prepared Connector 1 in the in FIG. 2 Mating connector 2, not shown, has been used, the connector housing 4 is moved relative to the contact partner housing 3, so that the tab 8 can act on the contact partner of the connector 1 to apply the required contact forces.

In Figur 2 ist schließlich noch dargestellt, dass der Steckverbinder 1 einen zusätzlichen Verriegelungsmechanismus 11 aufweisen kann, aber nicht aufweisen muss. Dieser Verriegelungsmechanismus 11 und ein zugehöriger Verriegelungsmechanismus an dem Gegensteckverbinder 2 bewirken, dass zusätzlich zu vorhandenen Rastmitteln, die ein Verriegeln des Steckverbinders 1 und des Gegensteckverbinders 2 im vollständig zusammengesteckten Zustand ermöglichen, noch eine weitere, d. h. zusätzliche Verriegelung realisiert ist, um weiter zu verhindern, dass sich die Steckverbinderanordnung während ihres Betriebes im Fahrzeug löst. Dabei ist dieser Verriegelungsmechanismus, auch CPA genannt, dazu ausgebildet, dass er durch eine zusätzliche Bewegung erst dann betätigt werden kann, wenn die Stellung erreicht ist, wie sie in Figur 1, links, dargestellt ist, d. h. wenn der Steckverbinder 1 vollständig in den Gegensteckverbinder 2 eingesteckt ist, das Steckverbindergehäuse 4 von seiner ersten Stellung über das Kontaktpartnergehäuse 3 in seine zweite Stellung in Richtung des Gegensteckverbinders 2 verschoben worden ist und auch die daraus resultierenden Kontaktkräfte aufgebracht worden sind.In FIG. 2 Finally, it is shown that the connector 1 may have an additional locking mechanism 11, but need not have. This locking mechanism 11 and an associated locking mechanism on the mating connector 2 cause, in addition to existing locking means, which allow a locking of the connector 1 and the mating connector 2 in the fully mated condition, yet another, ie additional locking is realized to further prevent that the connector assembly dissolves during its operation in the vehicle. In this case, this locking mechanism, also called CPA, is designed so that it can only be actuated by an additional movement when the position is reached, as in FIG. 1 , left, is shown, that is, when the connector 1 is fully inserted into the mating connector 2, the connector housing 4 has been moved from its first position on the contact partner housing 3 in its second position in the direction of the mating connector 2 and the resulting contact forces have been applied are.
