Description

Die Erfindung betrifft ein Verfahren sowie eine Steckverbindung für Hochvolt-Anwendungen gemäß den Merkmalen der Oberbegriffe der unabhängigen Patentansprüche.The invention relates to a method and a plug connection for high-voltage applications according to the features of the preambles of the independent claims.

Steckverbindungen für Hochvolt-Anwendungen, die zum Beispiel Einsatz in Elektro- oder Hybridfahrzeugen finden, sind grundsätzlich bekannt. Solche Steckverbindungen weisen einen Steckverbinder und einen Gegensteckverbinder auf, die miteinander korrespondieren und zusammengesteckt die Steckverbindung bilden. Zur Herstellung einer elektrischen Kontaktierung sind in dem Steckverbinder und dem Gegensteckverbinder, die jeweils ein Gehäuse aufweisen, Kontaktpartner angeordnet, die dann eine elektrische Verbindung zwischen diesen beiden Steckverbindern herstellen, wenn sie zusammengesteckt wurden. Allerdings ist bei Hochvolt-Anwendungen bei diesem Steckvorgang äußerste Vorsicht geboten, da mit Spannungen größer 45 Volt, im Regelfall etwa 300-400 Volt, gearbeitet wird, wobei bei unsachgemäßem Umgang mit solchen Spannungen eine Gefahr für das menschliche Leben gegeben ist. Daher sind unbedingt Sicherungsmaßnahmen zu ergreifen, um eine Gefährdung desjenigen zu vermeiden, der mit solchen Steckverbindungen arbeitet.Plug connections for high-voltage applications, which are used, for example, in electric or hybrid vehicles, are generally known. Such plug connections have a plug connector and a mating plug connector which correspond to one another and when plugged together form the plug connection. To establish electrical contact, contact partners are arranged in the connector and the mating connector, each of which has a housing, which then establish an electrical connection between these two connectors when they have been plugged together. In high-voltage applications, however, extreme caution is required with this plug-in process, as voltages greater than 45 volts, usually around 300-400 volts, are used, whereby improper handling of such voltages poses a risk to human life. It is therefore imperative to take safety measures to avoid endangering those who work with such plug connections.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Steckverbindung, aufweisend einen Steckverbinder sowie einen Gegensteckverbinder, die zusammengesteckt werden, bereitzustellen, der erhöhte Sicherheitsanforderungen beim Umgang im Hochvolt-Bereich erfüllt. Gleiches gilt für das Verfahren zum Betreiben einer Steckverbindung für Hochvolt-Anwendungen.The invention is therefore based on the object of providing a plug connection having a plug connector and a mating plug connector which are plugged together and which meet increased safety requirements when dealing with the high-voltage range. The same applies to the method for operating a plug connection for high-voltage applications.

Diese Aufgabe ist hinsichtlich der Steckverbindung dadurch gelöst, dass der Steckverbinder und der Gegensteckverbinder derart ausgebildet sind, dass sie nur dann von einer Vorverraststellung in eine Endverraststellung relativ zueinander bewegt werden können, wenn zwei voneinander unabhängige Mittel, die jeweils von dem Steckverbinder und von dem Gegensteckverbinder gebildet sind, betätigt werden. Zunächst hat das Einsetzen des Steckverbinders in den Gegensteckverbinder in eine Vorverraststellung den Vorteil, dass diese beiden Steckverbinder in eine definierte Lage zueinander gebracht worden sind, von der sie durch weitere Betätigung nicht ohne Weiteres in ihre Endverraststellung gebracht werden können. Dies erhöht die Montagesicherheit. Um nun sicherzustellen, dass der Steckverbinder von der Vorverraststellung erst dann in die Endverraststellung in den Gegensteckverbinder gebracht wird, ist es erfindungsgemäß vorgesehen, dass hierfür zwei voneinander unabhängige Mittel, die von den Steckverbindern gebildet sind, betätigt werden. Dadurch ist sichergestellt, dass von demjenigen, der die Steckverbindung zusammensteckt, ein ganz bewusster Vorgang ausgeführt wird, indem zwei voneinander unabhängige Mittel betätigt werden müssen. Damit ist sichergestellt, dass der Bedienperson bewusst ist, dass sie eine elektrische Steckverbindung für Hochvolt-Anwendungen betätigt und dabei besonders vorsichtig ist, da der Steckvorgang, bei dem auch die elektrische Kontaktierung stattfindet, ganz bewusst und nicht durch einfaches Zusammenstecken der beiden Steckverbinder ausgeführt werden muss. Die beiden voneinander unabhängigen Mittel, die von den Steckverbindern gebildet werden, können zum Beispiel zweistufig ausgebildet sein, sodass bei Aufbringung bestimmter Kräfte hintereinander zwei Widerstände überwunden werden müssen, bevor die Steckverbindung komplett zusammengesteckt und damit die elektrische Kontaktierung hergestellt ist. Alternativ oder ergänzend dazu ist es auch denkbar, dass eines oder beide der voneinander unabhängigen Mittel mit einem Werkzeug betätigt werden müssen. Dies erhöht das Bewusstsein für die Bedienperson und erhöht weiterhin die Sicherheit, da ohne ein Werkzeug die Steckverbindung nicht zusammengesteckt und damit elektrisch kontaktiert werden kann. In vorteilhafter Weise sind für den Steckvorgang zwei voneinander unterschiedliche oder auch zwei zweistufig zu betätigende Werkzeuge erforderlich. Dabei kann eines der Werkzeuge oder können auch beide Werkzeuge mit einer Sicherheitseinrichtung kontaktiert sein, sodass dann, wenn das Werkzeug nicht richtig betätigt wurde oder ohne Werkzeug die Steckverbindung (insbesondere durch Inkaufnahme einer Beschädigung) trotzdem zusammengesteckt wurde, Maßnahmen zur Absicherung und insbesondere zum Schutz der Bedienperson getroffen werden können.This object is achieved with regard to the plug connection in that the connector and the mating connector are designed in such a way that they can only be moved from a pre-locking position to a final locking position when two mutually independent means, each of the connector and the mating connector are formed, are operated. First of all, inserting the connector into the mating connector in a pre-locking position has the advantage that these two connectors have been brought into a defined position relative to one another, from which they cannot easily be brought into their final locking position by further actuation. This increases the assembly security. In order to ensure that the connector is only then brought from the pre-locking position into the end locking position in the mating connector, it is provided according to the invention that two mutually independent means, which are formed by the connectors, are actuated for this purpose. This ensures that the person who connects the plug-in connection carries out a very deliberate process in that two mutually independent means have to be actuated. This ensures that the operator is aware that he is actuating an electrical plug connection for high-voltage applications and is particularly careful because the plugging process, in which the electrical contact also takes place, is carried out deliberately and not by simply plugging the two connectors together got to. The two independent of each other Means that are formed by the plug connectors can be designed in two stages, for example, so that when certain forces are applied one behind the other, two resistances must be overcome before the plug connection is completely plugged together and the electrical contact is thus established. As an alternative or in addition to this, it is also conceivable that one or both of the mutually independent means must be actuated with a tool. This increases the awareness of the operator and further increases safety, since the plug-in connection cannot be plugged together and thus electrically contacted without a tool. Advantageously, two tools that are different from one another or also two tools to be operated in two stages are required for the plugging process. One of the tools or both tools can be contacted with a safety device so that if the tool was not operated correctly or the plug-in connection was nevertheless plugged together without a tool (in particular by accepting damage), measures to secure and in particular to protect the Operator can be met.

Gemäß der Erfindung sind am Gehäuse des Steckverbinders ein Vorsprung und am Gegensteckverbinder aus dem Gehäuse des Gegensteckverbinders herausbewegbar ein Block und ein Vorsprung ausgebildet. Der Vorsprung des Steckverbinders wird dabei beim Einstecken in den Gegensteckverbinder auf dessen Block geführt, sodass dadurch die Vorverraststellung erzielt wird. Durch Betätigung des Vorsprunges des Steckverbinders kann das weitere Hineinbewegen des Steckverbinders in den Gegensteckverbinder erfolgen, und zwar dann, wenn der Vorsprung des Steckverbinders über den Block und den Vorsprung des Gegensteckverbinders durch erhöhte Kraftaufbringung oder durch Einsatz eines Werkzeuges hinüberbewegt wird. Damit sind diese Mittel dazu ausgebildet, den Steckverbinder zum einen in der Vorverraststellung in dem Gegensteckverbinder anzuordnen und gleichzeitig sicherzustellen, dass nur durch zusätzliche Maßnahmen wie zum Beispiel einen höheren Kraftaufwand oder den Einsatz eines Werkzeuges der Steckverbinder von seiner Vorverraststellung in seine Endverraststellung gebracht werden kann. Dies kann aber erst dann erfolgen, wenn nicht nur die ersten Mittel, sondern auch die zweiten Mittel betätigt worden sind.According to the invention, a projection is formed on the housing of the connector and a block and a projection can be moved out of the housing of the mating connector on the mating connector. The projection of the connector is guided on its block when it is inserted into the mating connector, so that the pre-latching position is achieved as a result. By actuating the projection of the connector, the connector can be moved further into the mating connector, namely when the projection of the connector is moved over the block and the projection of the mating connector by applying increased force or by using a tool. These funds are thus trained to To arrange the connector on the one hand in the pre-locked position in the mating connector and at the same time ensure that the connector can only be brought from its pre-locked position to its final locked position by additional measures such as greater effort or the use of a tool. However, this can only take place when not only the first means but also the second means have been actuated.

Gemäß der Erfindung sind weitere Mittel des Steckverbinders eine abstehende Lasche mit einer Öffnung und weitere Mittel des Gegensteckverbinders eine abstehende Lasche mit einem Aufnahmeraum. Die beiden Laschen korrespondieren derart miteinander, dass beim Verbringen des Steckverbinders in den Gegensteckverbinder von der Vorverrast- in die Endverraststellung die abstehende Lasche des Steckverbinders in den Aufnahmeraum der abstehenden Lasche des Gegensteckverbinders eintaucht. Dies kann allerdings erst dann erfolgen, nachdem ein Werkzeug, ein Bolzen, ein Schloss oder dergleichen aus der Öffnung der abstehenden Lasche des Steckverbinders entfernt worden ist, da ansonsten dieses Werkzeug das Eintauchen der Lasche des Steckverbinders in den Aufnahmeraum der Lasche des Gegensteckverbinders blockiert. Somit bewirken die weiteren Mittel in vorteilhafter Weise, dass sie betätigt werden müssen, bevor endgültig die Steckverbindung zusammengesteckt werden kann, das heißt, dass der Steckverbinder von seiner Vorverraststellung in den Gegensteckverbinder in die Endverraststellung verbracht werden kann.According to the invention, further means of the connector are a protruding tab with an opening and further means of the mating connector are a protruding tab with a receiving space. The two tabs correspond to one another in such a way that when the connector is moved into the mating connector from the pre-latching to the end locking position, the protruding tab of the connector dips into the receiving space of the protruding tab of the mating connector. However, this can only be done after a tool, a bolt, a lock or the like has been removed from the opening of the protruding tab of the connector, since otherwise this tool blocks the immersion of the tab of the connector into the receiving space of the tab of the mating connector. The further means thus advantageously have the effect that they have to be actuated before the plug connection can finally be plugged together, that is to say that the connector can be moved from its pre-locked position into the mating connector into the end locked position.

Aus Sicherheitsgründen ist in Weiterbildung der Erfindung vorgesehen, dass die Kontaktpartner des Steckverbinders und des Gegensteckverbinders derart ausgebildet und in ihrem jeweiligen Gehäuse angeordnet sind, dass sie in der Vorverraststellung nicht elektrisch miteinander verbunden sind. Das heißt, dass sie beabstandet zueinander sind, wenn sich der Steckverbinder in der Vorverraststellung in dem Gegensteckverbinder befindet. Das bedeutet weiterhin, das die erste Mittel und die Lage der Kontaktpartner in den beiden Steckverbindern derart aufeinander abgestimmt sind, dass in der Vorverraststellung die miteinander zu kontaktierenden Kontaktpartner auf Abstand sind und in diesem Zustand eine elektrische Verbindung noch nicht gegeben ist. Dadurch kann die Steckverbindung schon vormontiert werden, wobei jedoch noch weitere Schritte wie vorstehend beschrieben erforderlich sind, um die elektrische Verbindung herzustellen.For safety reasons, a further development of the invention provides that the contact partners of the plug connector and the mating connector are designed and arranged in their respective housing in such a way that they are not electrically connected to one another in the pre-latched position. That is, they are spaced from each other when the connector is in the Vorverraststellung in the mating connector. This also means that the first means and the position of the contact partners in the two connectors are matched to one another in such a way that the contact partners to be contacted are at a distance in the pre-latching position and an electrical connection is not yet established in this state. As a result, the plug connection can already be preassembled, but further steps as described above are required in order to establish the electrical connection.

Je nach Anwendungsfall kann es ausreichend sein, dass mit den ersten und/oder zweiten bzw. weiteren Mitteln sichergestellt ist, dass die zusammengesetzte Steckverbindung ausreichend gesichert ist, das heißt, dass der Steckverbinder dauerhaft in dem Gegensteckverbinder in der Endverraststellung verbleibt. Sollte diese Sicherung mit den ersten und/oder zweiten Mitteln nicht ausreichend sein oder unabhängig davon eine weitere Sicherung erforderlich sein, ist in Weiterbildung der Erfindung vorgesehen, dass die Steckverbindung ein Verriegelungselement aufweist. Dieses Verriegelungselement ist derart ausgebildet, dass es erst in seine lagefixierende Position gebracht werden kann, wenn sich der Steckverbinder in der Endverraststellung, das heißt also in seiner korrekten Position in dem Gegensteckverbinder befindet.Depending on the application, it may be sufficient that the first and / or second or further means ensure that the assembled plug connection is sufficiently secured, that is, that the plug connector remains permanently in the mating plug connector in the end locked position. If this securing with the first and / or second means is not sufficient or if a further securing is required regardless of this, a further development of the invention provides that the plug connection has a locking element. This locking element is designed in such a way that it can only be brought into its position-fixing position when the connector is in the end locked position, that is to say in its correct position in the mating connector.

Die vorstehenden Ausführungen bezüglich der Ausgestaltung und Funktion der Steckverbindung gelten, auch in Bezug auf die geschilderten Vorteile, in gleicher Weise für das Verfahren zum Betreiben einer Steckverbindung für Hochvolt-Anwendungen.The above statements regarding the design and function of the plug connection apply in the same way to the method for operating a plug connection for high-voltage applications, also with regard to the advantages outlined.

Eine Steckverbindung ist hinsichtlich ihrer konstruktiven Ausgestaltung und ihres Verfahrens zum Betreiben in den Figuren dargestellt und im Folgenden erläutert.A plug connection is shown in the figures with regard to its structural design and its method of operation and is explained below.

In Figur 1 ist, soweit im Einzelnen dargestellt, ein Steckverbinder 1 (auch als Brückenstecker zu bezeichnen) dargestellt. Dieser Steckverbinder 1 weist ein Gehäuse 3 auf, wobei das Gehäuse 3 in vorteilhafter Weise in einem Kunststoffspritzgussverfahren hergestellt ist. In dem Gehäuse 3 sind ein Kontaktpartner oder mehrere Kontaktpartner 4 angeordnet, die in diesem Fall als Kontaktstifte ausgebildet sind. Die Kontaktpartner 4 können direkt in dem Gehäuse 3 oder in einem hier nicht dargestellten Kontaktträger, der dann in das Gehäuse 3 eingesetzt wird, angeordnet sein. Mit 5 ist eine Steckseite und mit 6 eine Kabelabgangsseite bezeichnet, wobei hier der Einfachheit halber die Kabel nicht dargestellt sind. Die mit 6 bezeichnete Kabelabgangsseite kann auch so gestaltet sein, dass dort keine Kabel herausgeführt werden, sondern dass auf dieser Seite 6 der Steckverbinder 1 bündig abschließt, so dass er als Brückenstecker ausgebildet ist. Im Falle eines solchen Brückensteckers bilden zwei der Kontaktpartner 4 eine Kurzschlussbrücke, so dass die entsprechenden damit kontaktierten Kontaktpartner des Gegensteckverbinders (siehe Figur 2) kurzgeschlossen werden.In Figure 1 is, as far as shown in detail, a connector 1 (also referred to as a bridge plug) is shown. This plug connector 1 has a housing 3, the housing 3 being advantageously manufactured in a plastic injection molding process. A contact partner or several contact partners 4, which in this case are designed as contact pins, are arranged in the housing 3. The contact partners 4 can be arranged directly in the housing 3 or in a contact carrier, not shown here, which is then inserted into the housing 3. 5 denotes a plug-in side and 6 denotes a cable outlet side, the cables not being shown here for the sake of simplicity. The cable outlet side labeled 6 can also be designed in such a way that no cables are led out there, but that the connector 1 terminates flush on this side 6, so that it is designed as a bridge plug. In the case of such a bridge connector, two of the contact partners 4 form a short-circuit bridge, so that the corresponding contact partners of the mating connector (see FIG Figure 2 ) short-circuited.

Figur 2 zeigt einen entsprechenden Gegensteckverbinder 2 (auch als Buchsengehäuse zu bezeichnen), in dem ebenfalls Kontaktpartner 7 angeordnet sind. Die Kontaktpartner 7 (hier als Buchsen ausgebildet) korrespondieren hinsichtlich ihrer Lage und Funktion mit den Kontaktpartnern 4 des Steckverbinders 1. Auch der Gegensteckverbinder 2 hat eine Steckseite 8 und eine Kabelabgangsseite 9 und weist ebenfalls ein Gehäuse 10 auf. Auch hier können die Kontaktpartner 7 in dem Gehäuse 10 angeordnet sein, wobei im Falle der Ausgestaltung des Gegensteckverbinders 2 gemäß Figur 2 ein nicht näher bezeichneter Kontaktträger vorhanden ist, in dem die Kontaktpartner 7 angeordnet sind. Figure 2 shows a corresponding mating connector 2 (also referred to as a socket housing), in which contact partners 7 are also arranged. The contact partners 7 (here designed as sockets) correspond in terms of their position and function to the contact partners 4 of the connector 1. The mating connector 2 also has a plug-in side 8 and a cable outlet side 9 and also has a housing 10. Here, too, the contact partners 7 can be arranged in the housing 10, wherein in the case of the configuration of the mating connector 2 according to FIG Figure 2 a not closer designated contact carrier is present, in which the contact partners 7 are arranged.

Wieder mit Blick auf die Figur 1 ist erkennbar, dass die ersten Mittel des Steckverbinders 1 als ein von dem Gehäuse 3 abstehender Vorsprung 11, insbesondere ein rampenförmiger Vorsprung, ausgebildet sind. Mit Blick auf Figur 2 ist erkennbar, dass die zweiten Mittel des Gegensteckverbinders 2 als ein Block 12 sowie ein Vorsprung 13 ausgebildet sind. Dabei wirken der Vorsprung 11 und der Block 12 sowie der Vorsprung 13 derart miteinander zusammen, dass beim Einsetzen des Steckverbinders 1 in den Gegensteckverbinder 2 der Vorsprung 11 zur Anlage an den Block 12 kommt und erst durch höheren Kraftaufwand oder durch Betätigung mit einem Werkzeug den Block 12 und/oder den Vorsprung 13 überwinden kann, um den Steckverbinder 1 vollständig von der Vorverraststellung in die Endverraststellung in dem Gegensteckverbinder zu bewegen. Der Block 12 und der Vorsprung 13 können auch derart gestaltet sein, dass der Vorsprung 11 nach Überwindung des Blockes 12 an dem Vorsprung 13 zur Anlage kommt, um damit den Steckverbinder 1 in seiner Vorverraststellung in dem Gegensteckverbinder 2 in seiner Lage zu fixieren. Erst wenn der Vorsprung 11 betätigt wurde, kann er den Vorsprung 13 überwinden, damit dann der Steckverbinder 1 von der Vorverrast- in die Endverraststellung in den Gegensteckverbinder 2 gebracht werden kann.Again facing that Figure 1 it can be seen that the first means of the connector 1 are designed as a projection 11 protruding from the housing 3, in particular a ramp-shaped projection. With a view to Figure 2 it can be seen that the second means of the mating connector 2 are designed as a block 12 and a projection 13. The projection 11 and the block 12 as well as the projection 13 cooperate with each other in such a way that when the connector 1 is inserted into the mating connector 2, the projection 11 comes to rest on the block 12 and the block only comes into contact with greater force or when operated with a tool 12 and / or the projection 13 can overcome in order to move the connector 1 completely from the Vorverraststellung in the Endverraststellung in the mating connector. The block 12 and the projection 13 can also be designed in such a way that the projection 11 comes to rest on the projection 13 after overcoming the block 12 in order to fix the connector 1 in its position in its pre-latched position in the mating connector 2. Only when the projection 11 has been actuated can it overcome the projection 13 so that the connector 1 can then be brought into the mating connector 2 from the pre-locked position into the final locked position.

Mit anderen Worten funktionieren die ersten Mittel des Steckverbinders 1, nämlich der Vorsprung 11 und die zweiten Mittel des Gegensteckverbinders 2, nämlich der Block 12 und der Vorsprung 13, folgendermaßen. Beim Einsetzen des Steckverbinders 1 in den Gegensteckverbinder 2 wird von dem Vorsprung 13 verhindert, dass der Vorsprung 11 über den Vorsprung 13 gleiten kann. Erst wenn der Block 12, insbesondere seine rampenförmige Ausgestaltung, von einem Werkzeug (beispielsweise ein Schraubendreher oder dergleichen) betätigt wurde, bewegt sich der Vorsprung 13 aus der axialen Bewegungsrichtung des Vorsprunges 11, so dass der Steckverbinder 1 weiter in Richtung in seiner Endverraststellung in den Gegensteckverbinder 2 bewegt werden kann. Dabei sind der Block 12 und der Vorsprung 13 so auslenkbar an dem Gehäuse 10 des Gegensteckverbinders 2 angeordnet, dass sie zusammen eine Art Lasche bilden, wobei diese Lasche, umfassend den Block 12 und den Vorsprung 13, durch Betätigung des Werkzeuges in Richtung außerhalb des Gehäuses 10 ausgelenkt wird. Nachdem diese Auslenkung stattgefunden hat und der Vorsprung 11 des Steckverbinders 1 an diesen vorbei geschoben wurde, kann der Steckverbinder 1 in seine Endverraststellung in Bezug auf den Gegensteckverbinder 2 gebracht werden und die Lasche mit dem Block 12 und dem Vorsprung 13 wieder in ihre ursprüngliche Position zurückkehren.In other words, the first means of the connector 1, namely the projection 11 and the second means of the mating connector 2, namely the block 12 and the projection 13, function as follows. When inserting the connector 1 into the mating connector 2, the projection 13 prevents the projection 11 from sliding over the projection 13. Only when the block 12, in particular its ramp-shaped design, from a Tool (for example a screwdriver or the like) has been actuated, the projection 13 moves out of the axial direction of movement of the projection 11, so that the connector 1 can be moved further in the direction of its Endverraststellung in the mating connector 2. The block 12 and the projection 13 are arranged so that they can be deflected on the housing 10 of the mating connector 2 that they together form a type of tab, this tab, comprising the block 12 and the projection 13, by actuating the tool in the direction outside the housing 10 is deflected. After this deflection has taken place and the projection 11 of the connector 1 has been pushed past it, the connector 1 can be brought into its end locked position with respect to the mating connector 2 and the tab with the block 12 and the projection 13 return to their original position .

Wiederum mit Blick auf die Figur 1 ist erkennbar, dass der Steckverbinder 1, genauer dessen Gehäuse 3, eine abstehende Lasche 14 mit einer Öffnung 15 aufweist. Korrespondieren dazu weist der Gegensteckverbinder 2, genauer dessen Gehäuse 10, ebenfalls eine abstehende Lasche 16 mit einem Aufnahmeraum 17 auf. Die geometrische Gestaltung der beiden Laschen 14, 16 ist dabei so gewählt, dass zumindest ein Teil der Lasche 14 in den Aufnahmeraum 17 der Lasche 16 eintauchen kann, wenn der Steckverbinder 1 von der Vorverrast- in die Endverraststellung gebracht worden ist. Dies ist jedoch erst dann möglich, wenn auch die Öffnung 15 der Lasche 14 in den Aufnahmeraum 17 der Lasche 16 eintauchen kann. Dies wird jedoch zuvor von einem in die Öffnung 15 einsetzbaren Werkzeug verhindert, um Fehlbedienungen der Steckverbindung zu verhindern. Erst wenn das Werkzeug aus der Öffnung 15 entfernt worden ist, ist es möglich, dass die Lasche 14 in den Aufnahmeraum der Lasche 16 eintaucht, wenn der Steckverbinder 1 von der Vorverrast- in die Endverraststellung in dem Gegensteckverbinder 2 bewegt wird.Again looking at the Figure 1 it can be seen that the connector 1, more precisely its housing 3, has a protruding tab 14 with an opening 15. Corresponding to this, the mating connector 2, more precisely its housing 10, likewise has a protruding tab 16 with a receiving space 17. The geometric design of the two tabs 14, 16 is selected so that at least part of the tab 14 can dip into the receiving space 17 of the tab 16 when the connector 1 has been brought from the pre-latched to the final latched position. However, this is only possible when the opening 15 of the tab 14 can also dip into the receiving space 17 of the tab 16. However, this is prevented beforehand by a tool which can be inserted into the opening 15 in order to prevent incorrect operation of the plug connection. Only when the tool has been removed from the opening 15 is it possible for the tab 14 to dip into the receiving space of the tab 16 when the plug connector 1 is moved from the Vorverrast- into the Endverraststellung in the mating connector 2.

Die vorstehend beschriebenen Elemente der beiden Steckverbinder 1, 2 sind noch einmal detailliert in den Figuren 3 und 4 dargestellt. Dabei ist ergänzend noch darauf hinzuweisen, dass die einzelnen Bestandteile der beiden Gehäuse 3, 10 so ausgeführt sind, dass sie eine möglichst lineare, spielfreie und damit widerstandsfreie Bewegung von der Vorverrast- in die Endverraststellung gestatten.The elements of the two connectors 1, 2 described above are detailed again in FIGS Figures 3 and 4th shown. It should also be pointed out that the individual components of the two housings 3, 10 are designed in such a way that they allow the most linear, play-free and thus resistance-free movement from the pre-locking position to the final locking position.

In den Figuren 5 und 6 ist ergänzend die Lage des Steckverbinders 1 in Bezug auf den Gegensteckverbinder 2 sowohl in der Vorverrast- als auch in der Endverraststellung zu erkennen. In diesem Zusammenhand kommt es nicht nur darauf an, dass zunächst der Steckverbinder 1 in die Vorverraststellung in Bezug zu dem Gegensteckverbinder gebracht wird (Figur 5, rechte Darstellungen in zwei verschiedenen Ansichten), sondern dass auch in dieser Vorverraststellung sichergestellt ist, dass die Kontaktpartner 4 des Steckverbinders 1 noch nicht mit den Kontaktpartnern 7 des Gegensteckverbinders 2 in Berührung gekommen sind. Das heißt in dieser Vorverraststellung ist noch keine elektrische Kontaktierung zwischen den zugehörigen Kontaktpartnern des Steckverbinders 1 und des Gegensteckverbinders 2 gegeben. Mit Blick auf die Figur 5 bedeutet dies, dass bei der rechts gezeigten Vorverraststellung eine sogenannte "OFF-Stellung" realisiert ist, bei der keine Kontaktpartner (auch als Pin zu bezeichnen) kontaktiert sind. Erst wenn der Steckverbinder 1 vollständig von der Vorverrast- in seine Endverraststellung in den Gegensteckverbinder 2 hineinbewegt worden ist (siehe Figur 5, linke Darstellungen aus verschiedenen Sichtweisen), werden die einander zugehörigen Kontaktpartner von Steckverbinder 1 und Gegensteckverbinder 2 elektrisch miteinander kontaktiert, wobei hierzu aber, wie vorstehend beschrieben, die zwei voneinander unabhängigen Mittel der Steckverbinder 1, 2 betätigt werden müssen. Dies ist bei der Bewegung, wie sie ausgehend von Figur 5, rechte Darstellung, hin zu Figur 5, linke Darstellung, gezeigt ist, erfolgt, jedoch nicht dargestellt. Das bedeutet, dass in der Endverraststellung (auch als "ON-Stellung", wie sie in Figur 5 links dargestellt ist) die Kontaktpartner 4 vollständig mit den Kontaktpartnern 7 verbunden sind. Das bedeutet mit anderen Worten (und mit Blick auf Figur 5), dass die Pins 1 und 3 des Steckverbinders 1 mit den Pins 2 und 4 des Gegensteckverbinders 2 elektrisch kontaktiert (kurzgeschlossen) sind.In the Figures 5 and 6th the position of the connector 1 in relation to the mating connector 2 can also be seen both in the pre-locking position and in the final locking position. In this context, it is not only important that the connector 1 is first brought into the pre-locked position in relation to the mating connector ( Figure 5 , right representations in two different views), but that it is also ensured in this pre-locking position that the contact partners 4 of the connector 1 have not yet come into contact with the contact partners 7 of the mating connector 2. This means that in this pre-locking position there is still no electrical contact between the associated contact partners of the connector 1 and the mating connector 2. With view on Figure 5 this means that in the pre-locking position shown on the right, a so-called "OFF position" is implemented, in which no contact partners (also referred to as pins) are contacted. Only when the connector 1 has been moved completely from the pre-locking position into its final locking position into the mating connector 2 (see Figure 5 , left representations from different perspectives), the associated contact partners of connector 1 and mating connector 2 are electrically contacted with each other, but for this purpose, as described above, the two mutually independent means of the connectors 1, 2 must be actuated. This is when moving as they are starting from Figure 5 , right representation, towards Figure 5 , left representation, is shown takes place, but not shown. This means that in the final latching position (also known as the "ON position" as shown in Figure 5 shown on the left) the contact partners 4 are completely connected to the contact partners 7. In other words, that means (and looking at Figure 5 ) that pins 1 and 3 of connector 1 are electrically connected to pins 2 and 4 of mating connector 2 (short-circuited).

Alternativ zu der vorstehend beschriebenen Ausgestaltung kann der Steckverbinder 1 gemäß Figur 1 bzw. 3 nicht als ein Steckverbinder ausgebildet sein, der an einem Ende eines Kabels angeordnet ist, sondern der als Brückenstecker ausgebildet ist. Das bedeutet, dass der Steckverbinder 1 auf der bisher als Kabelabgangsseite bezeichneten Seite endet und dort keine Kabel herausgeführt sind. Für diesen Fall ist der Brückenstecker als eine Art Kurzschlussstecker ausgebildet, der bewirkt, dass wenigstens zwei seiner Kontaktpartner 4 miteinander verbunden sind und diese, wenn der Steckverbinder 1 in den Gegensteckverbinder 2 eingesteckt wird, die korrespondierenden Kontaktpartner 7 des Gegensteckverbinders 2 kurzschließt.As an alternative to the embodiment described above, the connector 1 can according to FIG Figure 1 or 3 may not be designed as a connector which is arranged at one end of a cable, but which is designed as a bridge connector. This means that the connector 1 ends on the side previously referred to as the cable outlet side and no cables are led out there. In this case, the jumper plug is designed as a type of short-circuit plug, which has the effect that at least two of its contact partners 4 are connected to one another and that when the connector 1 is inserted into the mating connector 2, the corresponding contact partners 7 of the mating connector 2 are short-circuited.

Die gleiche Bewegungsfolge, wie sie in Figur 5 dargestellt ist, ist ebenfalls noch einmal in Figur 6 dargestellt, wobei hier zusätzlich ein Verriegelungselement 18 (siehe dessen geometrische Ausgestaltung in Figur 7) zum Einsatz kommt. Somit ist in Figur 6, obere Darstellung, gezeigt, dass der Steckverbinder 1 in seiner Vorverraststellung in den Gegensteckverbinder 2 eingesetzt ist. Dabei ist auch erkennbar, dass die Öffnung 15 der Lasche 14 zugänglich ist und die Lasche 14 nur teilweise in den Aufnahmeraum 17 der Lasche 16 eingetaucht. Nicht dargestellt, aber in dieser Stellung vorhanden, ist ein Werkzeug, welches durch die Öffnung 15 durchgeführt ist, um zu verhindern, dass der Steckverbinder 1 in den Gegensteckverbinder 2 weiter eintauchen kann. Erst wenn die ersten Mittel (Vorsprünge 11, 13 und Block 12, zugänglich durch eine Öffnung in dem Gehäuse 10 des Gegensteckverbinders 2) betätigt und das Werkzeug aus der Öffnung 15 entfernt worden ist, ist es möglich, den Steckverbinder 1 von seiner Vorverraststellung in die Endverraststellung in den Gegensteckverbinder zu bewegen. Dies ist in Figur 6, unten, linke Seite, dargestellt. In diesen beiden vorgenannten Zuständen hat das Verriegelungselement noch nicht seine endgültige Position erreicht, das heißt, dass es noch aus dem Steckverbinder 1 herausragt. Erst wenn der Steckverbinder 1 vollständig in seine Endverraststellung in Bezug auf den Gegensteckverbinder 2 gebracht worden ist, wird es aufgrund der Geometrie des Verriegelungselementes 18 möglich, dieses vollständig in seine endgültige Lage (die auch als Endverraststellung zu bezeichnen ist) gebracht werden kann. Dies ist in Figur 6, unten, rechte Darstellung, gezeigt, wobei in vorteilhafter Weise die eine Stirnseite des Verriegelungselementes 18 mit der Kabelabgangsseite 6 des Steckverbinders 1 abschließt. Dadurch ist auch optisch zu erkennen, dass sich das Verriegelungselement 18 in seiner Sollposition befindet, um den Steckverbinder 1 in dem Gegensteckverbinder 2 zur Realisierung einer funktionstüchtigen Steckverbindung zu sichern.The same sequence of movements as in Figure 5 is also shown again in Figure 6 shown, with an additional locking element 18 (see its geometric configuration in Figure 7 ) is used. Thus, in Figure 6 , Upper illustration shows that the connector 1 is inserted into the mating connector 2 in its pre-latched position. It can also be seen that the opening 15 of the tab 14 is accessible and the tab 14 is only partially immersed in the receiving space 17 of the tab 16. Not shown, but present in this position, is a tool which passes through the opening 15 is carried out in order to prevent the connector 1 from being able to plunge further into the mating connector 2. Only when the first means (projections 11, 13 and block 12, accessible through an opening in the housing 10 of the mating connector 2) has been actuated and the tool has been removed from the opening 15, it is possible to move the connector 1 from its Vorverraststellung into the End locking position to move into the mating connector. This is in Figure 6 , below, left side. In these two aforementioned states, the locking element has not yet reached its final position, that is to say that it is still protruding from the connector 1. Only when the connector 1 has been fully brought into its final locking position with respect to the mating connector 2 is it possible, due to the geometry of the locking element 18, to bring it fully into its final position (which can also be referred to as the final locking position). This is in Figure 6 , shown below, right-hand illustration, with one end face of the locking element 18 terminating with the cable outlet side 6 of the plug connector 1 in an advantageous manner. As a result, it can also be seen optically that the locking element 18 is in its desired position in order to secure the plug connector 1 in the mating plug connector 2 for realizing a functional plug connection.

Abschließend sei noch erwähnt, dass die beiden Steckverbinder 1, 2 üblicherweise am Ende eines jeweiligen Kabels angeordnet sind. Anstelle der Anordnung am Ende eines Kabels kann auch beispielsweise einer der beiden Steckverbinder Bestandteil eines Gehäuses eines elektronischen Gerätes (wie zum Beispiel ein Sensor, ein Aktor, ein Steuergerät oder dergleichen) sein.Finally, it should also be mentioned that the two plug connectors 1, 2 are usually arranged at the end of a respective cable. Instead of being arranged at the end of a cable, for example one of the two plug connectors can also be part of a housing of an electronic device (such as a sensor, an actuator, a control device or the like).
