Description

Die Erfindung betrifft eine Steckverbindung mit einem ersten Steckverbinder und einem zweiten Steckverbinder, wobei der erste und der zweite Steckverbinder jeweils mindestens ein elektrisches Kontaktelement aufweisen, die durch ein Zusammenstecken des ersten und des zweiten Steckverbinders kontaktierbar sind. Insbesondere betrifft die Erfindung eine Steckverbindung zur Verbindung von Hochstromleitungen, wie sie insbesondere in Kraftfahrzeugen mit einem elektrischen Fahrantrieb eingesetzt werden.The invention relates to a plug connection with a first connector and a second connector, wherein the first and the second connector each have at least one electrical contact element which can be contacted by a mating of the first and the second connector. In particular, the invention relates to a connector for connecting high-current lines, as used in particular in motor vehicles with an electric traction drive.

Eine solche gattungsgemäße Steckverbindung ist beispielsweise aus der DE 10 2009 053 779 B3 bekannt.Such a generic connector is for example from the DE 10 2009 053 779 B3 known.

Ein Problem, das sich bei derartigen Steckverbindungen für die Verbindung von Hochstromleitungen ergibt, liegt in der Ausgestaltung der miteinander zu verbindenden Kontaktelemente, von denen regelmäßig eines als Buchse und das andere als in die Buchse eingreifender Stecker ausgebildet ist. Um hohe Ströme übertragen zu können, sind diese Kontaktelemente mit großen Abmessungen ausgebildet. Weiterhin müssen die beiden Kontaktelemente unter einem relativ großen Druck miteinander kontaktiert werden, um eine sichere Übertragung der elektrischen Energie sicherzustellen. Dies führt bei einer Ausgestaltung der Kontaktelemente als Buchse und Stecker zu relativ großen Steck- bzw. Lösekräften.A problem that arises in such connectors for the connection of high-current lines, lies in the design of the interconnected contact elements, one of which is regularly formed as a socket and the other as engaging in the socket connector. In order to transmit high currents, these contact elements are designed with large dimensions. Furthermore, the two contact elements must be contacted with each other under a relatively large pressure to ensure a secure transmission of electrical energy. This leads in a configuration of the contact elements as a socket and plug to relatively large plug or release forces.

Bekannt ist, diese Steck- und Lösekräfte über eine Schraubverbindung aufzubringen. Andere Ausführungsformen sehen vor, die Steck- bzw. Lösekräfte über einen Hebel aufzubringen, der beim Verschwenken die beiden Steckverbinder über eine Kulisse zueinander bewegt. Eine solche Steckverbindung ermöglicht zwar eine komfortable und schnelle Kontaktierung der beiden Steckverbinder, benötigt jedoch infolge der Schwenkbewegung des Hebels einen großen Raumbedarf, der insbesondere bei einer Verwendung in einem Motorraum eines Kraftfahrzeugs häufig nicht zur Verfügung steht.It is known to apply these plug and release forces via a screw connection. Other embodiments provide to apply the plug or release forces via a lever, the two connectors when pivoting over a Backdrop to each other moves. Although such a connector allows a comfortable and quick contact of the two connectors, but requires due to the pivoting movement of the lever a large space, which is often not available, especially when used in an engine compartment of a motor vehicle.

An gattungsgemäße Steckverbindungen, insbesondere an solche, die in Kraftfahrzeugen eingesetzt werden, werden noch weitere Anforderungen gestellt. Diese betreffen insbesondere die Sicherheit des die Steckverbinder zusammensteckenden Montagepersonals sowie den Schutz der im Kraftfahrzeug verbauten elektronischen Komponenten. So ist beispielsweise vorgesehen, neben den für die Übertragung des Hochstroms vorgesehenen Kontaktelementen, noch weitere Kontaktelemente in die Steckverbinder zu integrieren, die einen Teil eines (12V-)Niederspannungs-Sicherungsstromkreises sind. Vorgesehen ist, die über den Steckverbinder zu verbindenden Hochstromleitungen nur dann mit der Hochspannung zu beaufschlagen, wenn die weiteren, in den Niederspannungs-Sicherungsstromkreis integrierten Kontaktelemente ebenfalls kontaktiert sind. Demnach sind die Steckverbinder derart ausgebildet, dass bei der Steckbewegung zunächst die Kontaktelemente für die Hochstromleitungen und dann erst die Kontaktelemente für den Niederspannungs-Sicherungsstromkreis kontaktieren. Beim Lösen werden zunächst die Kontaktelemente des Niederspannungs-Sicherungsstromkreises gelöst, wodurch - sofern nicht bereits erfolgt - eine Hochspannungsbeaufschlagung der Hochstromleitungen unterbrochen wird. Dann erst werden die Kontaktelemente der Hochstromleitungen außer Kontakt gebracht. Dadurch wird sichergestellt, dass die Hochstromleitungen nur dann mit Hochspannung beaufschlagt sind, wenn die für die Hochstromübertragung vorgesehenen Kontaktelemente der Steckverbindungen sicher kontaktieren. Ein Überschlag beim Stecken bzw. Lösen der Steckverbindung bei anliegender Hochspannung, der zu einer Verletzung des Montagepersonals und zu einem Verbrennen der Kontaktelemente führen könnte, wird dadurch vermieden.To generic connectors, especially those that are used in motor vehicles, further demands are made. These relate in particular to the safety of the assembly personnel plugging together connectors and the protection of the electronic components installed in the motor vehicle. For example, it is provided, in addition to the intended for the transmission of high current contact elements, to integrate other contact elements in the connector, which are part of a (12V) low-voltage fuse circuit. It is intended to apply the high-voltage lines to be connected via the connector only when the other, integrated into the low-voltage fuse circuit contact elements are also contacted. Accordingly, the connectors are designed such that first contact the contact elements for the high-current lines and then only the contact elements for the low-voltage fuse circuit in the plug movement. When releasing the contact elements of the low-voltage fuse circuit are first solved, whereby - if not already done - a Hochspannungsbeaufschlagung the high-current lines is interrupted. Only then are the contact elements of the high current lines out of contact. This ensures that the high-current lines are only exposed to high voltage when the provided for the high-current transmission contact elements of the connectors securely contact. A rollover when inserting or releasing the connector with applied high voltage, which could lead to injury to the assembly personnel and to a burning of the contact elements, thereby avoided.

Die Druckschrift EP 0 696 828 A1 beschreibt eine Steckverbindung, bei der ein erster Steckverbinder durch Verschwenkung eines Handgriffs derart mit einem zweiten Steckverbinder verkuppelt wird, dass die Kontaktelemente der Steckverbinder kontaktieren.The publication EP 0 696 828 A1 describes a connector in which a first connector is coupled by pivoting a handle in such a way with a second connector that contact the contact elements of the connector.

Ausgehend von diesem Stand der Technik lag der Erfindung die Aufgabe zugrunde, eine gattungsgemäße, insbesondere für Hochstromanwendungen in Kraftfahrzeugen vorgesehene Steckverbindung weiter zu verbessern. Insbesondere sollte sich die Steckverbindung durch ein einfaches und sicheres Kontaktieren sowie einen geringen Platzbedarf beim Stecken auszeichnen.
Diese Aufgabe wird durch eine Steckverbindung gemäß dem unabhängigen Anspruch 1 gelöst. Vorteilhafte Ausgestaltungen der erfindungsgemäßen Steckverbindung sind Gegenstand der abhängigen Ansprüche und ergeben sich aus der nachfolgenden Beschreibung der Erfindung.
Eine gattungsgemäße Steckverbindung mit einem ersten Steckverbinder und einem zweiten Steckverbinder, die jeweils mindestens ein (erstes) elektrisches Kontaktelement aufweisen, die durch ein Zusammenstecken des ersten und des zweiten Steckverbinders kontaktierbar sind, ist erfindungsgemäß dadurch gekennzeichnet, dass der erste Steckverbinder ein erstes Verriegelungselement aufweist, mit dem ein zweites Verriegelungselement des zweiten Steckverbinders in einer Verriegelungsstellung der Steckverbindung zug- und/oder schubfest verrastbar ist, wobei das erste und/oder das zweite Verriegelungselement durch eine Verschiebevorrichtung in Form einer oder mehrerer Gewindespindeln in Steckrichtung relativ zu dem Kontaktelement des dazugehörigen Steckverbinders in eine (erste) Kontaktstellung der Steckverbindung verschiebbar ist/sind, um die Kontaktelemente des ersten und des zweiten Steckverbinders zu kontaktieren. Das Verschieben wird mittels einer Gewindespindel bewirkt.
Durch die erfindungsgemäße Ausgestaltung einer gattungsgemäßen Steckverbindung kann ein sicheres und komfortables Stecken (Zusammenstecken/Lösen) realisiert werden. Ermöglicht wird nämlich, in einem ersten Schritt die beiden Steckverbinder manuell zusammenzustecken und mittels der erfindungsgemäßen Rastverbindung zu verriegeln. Dadurch können diese bereits derart miteinander verbunden sein, dass ein unbeabsichtigtes (vollständiges) Lösen nicht mehr erfolgen kann. Dies ermöglicht, die Steckverbindung loszulassen oder in nur noch einer Hand zu halten. Dann - in einem zweiten Schritt - können durch den Einsatz der auf das erste und/oder das zweite Verriegelungselement wirkenden Verschiebevorrichtung die beiden Steckverbinder bzw. zumindest deren Kontaktelemente relativ zueinander bewegt werden, um diese zu kontaktieren. Durch die Möglichkeit, die Steckverbindung aus der Hand zu legen oder zumindest mit nur einer Hand halten zu können, ohne dass sich die beiden Steckverbinder vollständig voneinander lösen, kann mit zumindest einer freien Hand die Verschiebevorrichtung betätigt werden.Based on this prior art, the present invention seeks to further improve a generic, in particular intended for high current applications in motor vehicles connector. In particular, the connector should be characterized by a simple and secure contacting and a small footprint when plugging.
This object is achieved by a connector according to the independent claim 1. Advantageous embodiments of the connector according to the invention are the subject of the dependent claims and will become apparent from the following description of the invention.
A generic connector having a first connector and a second connector, each having at least one (first) electrical contact element, which can be contacted by a mating of the first and the second connector, according to the invention is characterized in that the first connector has a first locking element, with the second locking element of the second connector in a locking position of the connector zug- and / or shear-resistant latched, wherein the first and / or the second locking element by a displacement device in the form of one or more threaded spindles in the insertion direction relative to the contact element of the associated connector in a (first) contact position of the connector is displaceable / is to contact the contact elements of the first and the second connector. The displacement is effected by means of a threaded spindle.
The inventive design of a generic connector, a safe and comfortable plugging (plugging / releasing) can be realized. This makes it possible, in a first step, to manually plug together the two connectors and to lock them by means of the locking connection according to the invention. As a result, they can already be connected to one another in such a way that an unintentional (complete) release can no longer take place. This allows you to let go of the connector or hold in just one hand. Then - in a second step - can through the use of acting on the first and / or the second locking element displacement device, the two connectors or at least their contact elements are moved relative to each other to contact them. The ability to put the connector out of hand or at least hold it with one hand without the two connectors completely separate from each other, with at least one free hand, the displacement device can be actuated.

Die Verschiebevorrichtung ist erfindungsgemäß in Form einer oder mehrerer Gewindespindeln ausgebildet, über die einfach und komfortabel ausreichend hohe Kräfte aufgebracht werden können, um auch große Kontaktelemente, wie sie für Steckverbindungen für Hochstromanwendungen üblich sind, sicher miteinander kontaktieren zu können.
Vorzugsweise ist vorgesehen, dass die Verrastung der Verriegelungselemente zug- und schubfest ausgeführt ist, so dass über die Verschiebevorrichtung nicht nur die Steckbewegung zur Kontaktierung der beiden Kontaktelemente hergestellt werden kann, sondern auch die in entgegengesetzter Richtung erfolgende Lösebewegung.
Unter "zugfest" wird eine Ausgestaltung verstanden, die eine Übertragung einer Zugbelastung über die Verrastung ermöglicht. Unter "schubfest" wird dementsprechend eine Ausgestaltung verstanden, die die Übertragung von Druckkräften über die Verrastung ermöglicht. Dabei bezieht sich die Richtung der Druck- bzw. Zugbelastung auf die Steck- bzw. Löserichtung der Steckverbindung.
In einer bevorzugten Ausführungsform der erfindungsgemäßen Steckverbindung kann vorgesehen sein, dass das erste Verriegelungselement in Form eines Vorsprungs oder einer Vertiefung und das zweite Verriegelungselement in Form einer elastisch auslenkbaren, den Vorsprung umgreifenden oder in die Vertiefung eingreifenden Verriegelungslasche ausgebildet ist. Dies stellt eine konstruktiv einfache und kostengünstige Möglichkeit zur Ausbildung einer wiederholt einsetzbaren Verrastung dar.
Weiterhin bevorzugt kann eine Lösevorrichtung vorgesehen sein, die die Verrastung des ersten und des zweiten Verriegelungselements in einer Lösestellung der Steckverbindung löst, in der die Kontaktelemente nicht kontaktieren. Vorzugsweise ist dabei vorgesehen, dass die Steckverbindung ausgehend von der Verriegelungsstellung durch eine Zugbelastung der beiden Steckverbinder in die Lösestellung bringbar ist. Dementsprechend kann vorgesehen sein, dass zum (vollständigen) Lösen der beiden Steckverbinder voneinander diese zunächst mittels der Verschiebevorrichtung (wieder) in die Verriegelungsstellung gebracht werden und dann durch die Zugbelastung das vollständige Lösen erfolgt, wobei dabei die Lösestellung der Steckverbindung durchlaufen wird. Diese Ausgestaltung ermöglicht ein schnelles und komfortables Lösen der Steckverbindung.The displacement device according to the invention is designed in the form of one or more threaded spindles, over which easily and comfortably sufficiently high forces can be applied to securely contact even large contact elements, as are common for connectors for high-current applications.
Preferably, it is provided that the latching of the locking elements is designed to be tensile and shear-resistant, so that not only the plugging movement for contacting the two contact elements can be produced via the displacement device, but also the release movement taking place in the opposite direction.
By "tensile strength" is meant a design which allows transmission of a tensile load via the latching. By "shear-resistant" is accordingly understood an embodiment that allows the transmission of compressive forces on the latching. In this case, the direction of the pressure or tensile load refers to the plug or release direction of the connector.
In a preferred embodiment of the connector according to the invention can be provided that the first locking element in the form of a projection or a recess and the second locking element in the form of an elastically deflectable, embracing the projection or engaging in the recess locking tab is formed. This represents a structurally simple and cost-effective way to form a repeatedly usable latching.
Further preferably, a release device may be provided which solves the latching of the first and the second locking element in a release position of the connector in which the contact elements do not contact. Preferably, it is provided that the connector, starting from the locking position can be brought by a tensile load of the two connectors in the release position. Accordingly, it may be provided that for the (complete) release of the two connectors from each other this first by means of the displacement device (Re) be brought into the locking position and then the tension is released completely, in which case the release position of the connector is traversed. This embodiment allows a quick and comfortable release of the connector.

Eine solche Lösevorrichtung kann dann auf einfache Weise dadurch ausgebildet sein, dass das erste und das zweite Verriegelungselement Schrägflächen aufweisen, die derart ausgebildet sind, dass die Bewegung der beiden Steckverbinder in die Lösestellung (infolge eines Gleitens der Schrägflächen aufeinander) zu einem Auslenken eines der beispielsweise als elastische Verriegelungslasche ausgebildeten Verriegelungselemente führt.Such a release device can then be formed in a simple manner in that the first and the second locking element having inclined surfaces which are formed such that the movement of the two connectors in the release position (due to sliding of the inclined surfaces on each other) to a deflection of the example as an elastic locking tab formed locking elements leads.

Um die Steckverbindung nach dem vollständigen Lösen der beiden Steckverbinder voneinander wieder für ein nachfolgendes Zusammenstecken vorzubereiten, kann vorgesehen sein, dass das erste und/oder das zweite Verriegelungselement nach dem vollständigen Lösen der Steckverbindung selbsttätig wieder die Verriegelungsstellung einnimmt. Dies kann durch ein in der Lösestellung vorgespanntes Federelement erreicht werden.To prepare the connector after the complete release of the two connectors again from each other for a subsequent mating, it can be provided that the first and / or the second locking element automatically assumes the locking position again after the complete release of the connector. This can be achieved by a biased in the release position spring element.

Der erste und der zweite Steckverbinder der erfindungsgemäßen Steckverbindung können jeweils mindestens ein zweites elektrisches Kontaktelement aufweisen, die bereits in der Verriegelungsstellung kontaktieren. Bei diesen Kontaktelementen kann es sich vorzugsweise um Massekontaktelemente handeln, die insbesondere auch in Form einer die ersten Kontaktelemente umgebenden Abschirmung ausgebildet sein können.The first and the second connector of the connector according to the invention may each have at least one second electrical contact element, which already contact in the locking position. These contact elements may preferably be ground contact elements, which may in particular also be in the form of a shield surrounding the first contact elements.

Weiterhin kann der erste und der zweite Steckverbinder jeweils mindestens ein weiteres (gegebenenfalls drittes) elektrisches Kontaktelement aufweisen, die in einer zweiten Kontaktstellung kontaktieren, wobei die zweite Kontaktstellung durch ein Verschieben des ersten und/oder des zweiten Verriegelungselements ausgehend von der Verriegelungsstellung über die erste Kontaktstellung hinaus erreicht wird. Bei diesen Kontaktelementen kann es sich vorzugsweise um solche handeln, die in einen Niederspannungs-Sicherungsstromkreis integriert sind. Über diesen kann die Beaufschlagung der ersten Kontaktelemente mit einer Hochspannung gesteuert werden. Insbesondere kann vorgesehen sein, dass die ersten Kontaktelemente der erfindungsgemäßen Steckverbindung erst dann mit einer Spannung beaufschlagt werden, wenn eine Kontaktierung der Kontaktelemente des Niederspannungs-Sicherungsstromkreises vorliegt. Da die zweite Kontaktstellung (bezogen auf die Zusammensteckbewegung der beiden Steckverbinder) ausgehend von der Verriegelungsstellung hinter der ersten Kontaktstellung liegt, wird sichergestellt, dass die ersten Kontaktelemente immer dann kontaktieren, wenn dies auch für die weiteren Kontaktelemente gilt.Furthermore, the first and the second connector each have at least one further (possibly third) electrical contact element, which contact in a second contact position, wherein the second contact position by moving the first and / or the second locking element, starting from the locking position on the first contact position is reached out. These contact elements may preferably be those which are integrated in a low-voltage fuse circuit. About this, the admission of the first contact elements with a high voltage controlled become. In particular, it can be provided that the first contact elements of the connector according to the invention are only then applied with a voltage when a contact of the contact elements of the low-voltage fuse circuit is present. Since the second contact position (based on the mating movement of the two connectors), starting from the locking position behind the first contact position, it is ensured that the first contact elements always contact, if this also applies to the other contact elements.

In einer weiterhin bevorzugten Ausführungsform der erfindungsgemäßen Steckverbindung kann eine Sicherungseinrichtung vorgesehen sein, die ein Lösen der Verrastung des ersten und des zweiten Verriegelungselements in der ersten und/oder zweiten Kontaktstellung verhindert. Ein ungewolltes bzw. unzulässiges Lösen der Steckverbindung in der/den Kontaktstellung/en kann dadurch vermieden werden.In a further preferred embodiment of the connector according to the invention, a securing device may be provided which prevents release of the latching of the first and the second locking element in the first and / or second contact position. An unintentional or inadmissible loosening of the connector in the / the contact position / s can be avoided.

In einer weiterhin bevorzugten Ausführungsform der erfindungsgemäßen Steckverbindung kann ein Dichtelement vorgesehen sein, das in der ersten und/oder der zweiten Kontaktstellung in einem zwischen dem ersten und dem zweiten Steckverbinder ausgebildeten Spalt deformiert wird und das in der Verriegelungsstellung nicht deformiert wird. Ein solches Dichtelement kann die für ein Verbinden der beiden Steckverbinder erforderlichen Kräfte erheblich erhöhen. Durch diese bevorzugte Ausgestaltung kann sichergestellt werden, dass diese Kräfte nur dann von dem Dichtelement erhöht werden, wenn die Relativbewegung zwischen den Steckverbindern über die Verschiebeeinrichtung erzeugt wird. Ein manuelles Zusammenstecken der beiden Steckverbinder bis zur Verriegelungsstellung wird demnach nicht durch das Dichtelement erschwert.In a further preferred embodiment of the connector according to the invention, a sealing element may be provided which is deformed in the first and / or the second contact position in a gap formed between the first and the second connector and which is not deformed in the locking position. Such a sealing element can significantly increase the forces required for connecting the two connectors. By this preferred embodiment can be ensured that these forces are only increased by the sealing element when the relative movement between the connectors is generated via the displacement device. A manual mating of the two connectors to the locking position is therefore not complicated by the sealing element.

Die in den Fig. 1 bis 6 dargestellte Steckverbindung umfasst einen ersten Steckverbinder 1 sowie einen zweiten Steckverbinder 2. Die Steckverbinder 1, 2 dienen dazu, zur Übertragung von Hochstrom vorgesehene Leitungen miteinander zu verbinden. Während der erste Steckverbinder 1 zur Anbindung an insgesamt zwei Hochstromkabel 3 vorgesehen ist, ist der zweite Steckverbinder für ein Anflanschen an ein Gehäuse eines anderen Bauteils (nicht dargestellt), beispielsweise eines Elektromotors zum Antrieb eines Kraftfahrzeugs ausgebildet.The in the Fig. 1 to 6 shown connector comprises a first connector 1 and a second connector 2. The connectors 1, 2 serve to connect to the transmission of high current lines provided. While the first connector 1 is provided for connection to a total of two high-current cable 3, the second connector for flanging to a housing of another component (not shown), for example, an electric motor for driving a motor vehicle is formed.

Der erste Steckverbinder 1 ist mit zwei innerhalb eines Gehäuses 7 angeordneten steckerförmigen (Hochstrom-)Kontaktelementen 4 versehen, die jeweils mit einem der Hochstromkabel 3 verbunden sind. Zur elektrischen Kontaktierung (in einer Kontaktstellung) der Steckverbindung sollen die beiden steckerförmigen Hochstromkontaktelemente 4 des ersten Steckverbinders 1 in buchsenförmige Hochstromkontaktelemente 5 des zweiten Steckverbinders 2 eingesteckt werden. Dazu müssen die beiden Steckverbinder 1, 2 in Steckrichtung der Steckverbindung (diese entspricht der Längsrichtung der Kontaktelemente 4, 5 des ersten und des zweiten Steckverbinders 1, 2) relativ zueinander bewegt, d.h. zusammengeschoben werden.The first connector 1 is provided with two plug-shaped (high-current) contact elements 4 arranged within a housing 7, which are each connected to one of the high-current cables 3. For electrical contacting (in a contact position) of the plug connection, the two plug-shaped high-current contact elements 4 of the first connector 1 are to be plugged into socket-shaped high-current contact elements 5 of the second connector 2. For this purpose, the two connectors 1, 2 in the insertion direction of the connector (this corresponds to the longitudinal direction of the contact elements 4, 5 of the first and the second connector 1, 2) relative to each other moves, i. be pushed together.

Die Fig. 1 zeigt die Steckverbindung in einer entriegelten Stellung der beiden Steckverbinder 1, 2, d.h. die beiden Steckverbinder 1, 2 wurden bereits aneinander angesetzt, sind jedoch noch nicht miteinander verbunden.The Fig. 1 shows the connector in an unlocked position of the two connectors 1, 2, ie, the two connectors 1, 2 have already been attached to each other, but are not yet connected.

Ein erstes Verbinden der beiden Steckverbinder 1, 2 erfolgt in einer in der Fig. 2 dargestellten Verriegelungsstellung der Steckverbindung mittels miteinander verrastender Verriegelungselemente der beiden Steckverbinder. Der erste Steckverbinder 1 weist hierzu einen Verriegelungsbügel 6 auf, der (in Grenzen) in Steckrichtung der Steckverbindung auf dem Gehäuse 7 des ersten Steckverbinders 1 verschiebbar gelagert ist. Der Verriegelungsbügel 6 umfasst zwei seitlich angeordnete Verriegelungslaschen 8, deren jeweils eines Ende über eine Brücke 9 des Verriegelungsbügels 6 miteinander verbunden sind. Die Verriegelungslaschen 8 sind aus einem elastisch verformbaren Werkstoff gefertigt, um ein definiertes seitliches Auslenken der freien Enden der Verriegelungslaschen 8 zu ermöglichen. Im Bereich ihrer freien Enden sind die Verriegelungslaschen 8 mit jeweils einer Verriegelungsöffnung 10 versehen. Diese sollen jeweils einen Verriegelungsvorsprung 11, der von einem Gehäuse 12 des zweiten Steckverbinders 2 ausgebildet ist, umgreifen, um eine formschlüssige Verbindung zwischen dem ersten Steckverbinder 1 und dem zweiten Steckverbinder 2 herzustellen. Diese formschlüssige Verbindung ermöglicht die Übertragung von sowohl Zugkräften als auch Druckkräften (bezogen auf die Steckrichtung).A first connection of the two connectors 1, 2 takes place in a in the Fig. 2 illustrated locking position of the connector by means of latching locking elements of the two connectors. For this purpose, the first connector 1 has a locking clip 6 which is displaceably mounted (in limits) in the insertion direction of the plug connection on the housing 7 of the first connector 1. The locking bracket 6 comprises two laterally arranged locking tabs 8, one end of which is connected to each other via a bridge 9 of the locking bracket 6. The locking tabs 8 are made of an elastically deformable material to allow a defined lateral deflection of the free ends of the locking tabs 8. In the region of their free ends, the locking tabs 8 are each provided with a locking opening 10. These are each a locking projection 11, which is formed by a housing 12 of the second connector 2, engage around to form a positive connection between the first connector 1 and the second connector 2. This positive connection allows the transmission of both tensile forces and compressive forces (relative to the direction of insertion).

Um die Verriegelungsstellung der Steckverbindung gemäß Fig. 2 zu erreichen, werden die beiden Steckverbinder 1, 2 manuell so weit zusammengebracht, dass die Verriegelungsvorsprünge 11 des zweiten Steckverbinders 2 in die Verriegelungsöffnungen 10 der Verriegelungslaschen 8 des ersten Steckverbinders 1 eingreifen. Hierzu ist ein Auslenken der Verriegelungslaschen 8 erforderlich, was selbsttätig mittels aufeinander gleitenden Schrägflächen 13 der Verriegelungsvorsprünge 11 sowie der Verriegelungslaschen 8 und infolge der Relativbewegung der beiden Steckverbinder 1, 2 erfolgt. Nach dem Verrasten der Verriegelungsvorsprünge 11 und der Verriegelungslaschen 8 ist ein weitergehendes Zusammenstecken der beiden Steckverbinder 1, 2 durch lediglich das Aufbringen von (manuellen) Druckkräften auf die beiden Steckverbinder 1, 2 nicht mehr möglich.To the locking position of the connector according to Fig. 2 To achieve the two connectors 1, 2 are manually brought together so far that the locking projections 11 of the second connector 2 engage in the locking holes 10 of the locking tabs 8 of the first connector 1. For this purpose, a deflection of the locking tabs 8 is required, which is done automatically by means of successive sliding inclined surfaces 13 of the locking projections 11 and the locking tabs 8 and as a result of the relative movement of the two connectors 1, 2. After locking the locking projections 11 and the locking tabs 8 is a further mating the two connectors 1, 2 by only the application of (manual) compressive forces on the two connectors 1, 2 no longer possible.

In der in der Fig. 2 dargestellten Verriegelungsstellung kontaktieren die Hochstromkontaktelemente 4, 5 des ersten 1 und des zweiten Steckverbinders 2 noch nicht elektrisch leitend (obwohl sie schon mechanisch kontaktieren; elektrisch isolierende Kopfelemente 14 der steckerförmigen Hochstromkontaktelemente 4 des ersten Steckverbinders 1 verhindern jedoch eine elektrisch leitende Kontaktierung). Dagegen liegt jedoch schon ein elektrisch leitender Kontakt zwischen jeweils zwei Massekontaktelementen 15, 16 der beiden Steckverbinder vor. Die Massekontaktelemente 15 des zweiten Steckverbinders 2 sind dabei als ringförmige Stecker ausgebildet, die in jeweils eine mit federnden Laschen versehene Buchse (Massekontaktelement 16) des ersten Steckverbinders 1 eingreifen.In the in the Fig. 2 The locking position shown contact the high current contact elements 4, 5 of the first 1 and the second connector 2 is not electrically conductive (although they already contact mechanically, electrically insulating head elements 14 of the plug-shaped high current contact elements 4 of the first connector 1, however, prevent an electrically conductive contact). On the other hand However, there is already an electrically conductive contact between two ground contact elements 15, 16 of the two connectors. The ground contact elements 15 of the second connector 2 are formed as annular plug, which engage in each one provided with resilient lugs socket (ground contact element 16) of the first connector 1.

Um die Hochstromkontaktelemente 4, 5 der beiden Steckverbinder 1, 2 elektrisch leitend zu kontaktieren, ist es nunmehr erforderlich, den Verriegelungsbügel 6 auf dem Gehäuse 7 des ersten Steckverbinders 1 in Richtung der Hochstromkabel 3 zu verschieben. Dabei wird die Bewegung des Verriegelungsbügels 6 über die formschlüssige Verbindung zwischen den Verriegelungslaschen 8 und den Verriegelungsvorsprüngen 11 auf den zweiten Steckverbinder 2 übertragen, der dadurch in den ersten Steckverbinder hineingezogen wird.In order to contact the high-current contact elements 4, 5 of the two connectors 1, 2 electrically conductive, it is now necessary to move the locking bracket 6 on the housing 7 of the first connector 1 in the direction of the high-current cable 3. In this case, the movement of the locking bracket 6 is transmitted via the positive connection between the locking tabs 8 and the locking projections 11 on the second connector 2, which is thereby drawn into the first connector.

Das Verschieben des Verriegelungsbügels 6 auf dem Gehäuse 7 des ersten Kontaktsteckers 1 wird über zwei Führungsvorsprünge 17 des Gehäuses 7, die jeweils in eine Führungsnut 18 einer der Verriegelungslaschen 8 ragen, geführt und mittels einer Gewindespindel bewirkt, die einen Gewindebolzen 19 sowie einen Kopf 20 umfasst. An den Kopf kann ein Werkzeug angesetzt werden, um die Gewindespindel zu rotieren. Der Kopf 20 der Gewindespindel ist in einer Durchgangsöffnung eines kabelseitigen Teils des Gehäuses 7 drehbar, jedoch mittels eines C-Rings 21 in axialer Richtung festgelegt gelagert. Der Gewindebolzen 19 durchgreift eine Durchgangsöffnung der Brücke 9 des Verriegelungsbügels 6, wobei ein Außengewinde des Gewindebolzens 19 mit einem Innengewinde der Durchgangsöffnung im Eingriff ist. Das dem Kopf 20 gegenüber liegende Ende des Gewindebolzens 19 ist gewindefrei und in einer Öffnung einer in dem Gehäuse 7 gehaltenen Lagerplatte 22 drehbar gelagert. Zum Verschieben des Verriegelungsbügels 6 wird die Gewindespindel mittels eines Werkzeugs im Uhrzeigersinn rotiert, wobei die Rotation des Gewindebolzens 19 durch den Gewindeeingriff mit dem Verriegelungsbügel 6 in eine Translation des Verriegelungsbügels 6 relativ zu dem Gehäuse 7 (und den darin angeordneten Kontaktelementen) des ersten Steckverbinders 1 führt.The displacement of the locking bracket 6 on the housing 7 of the first contact plug 1 is guided via two guide projections 17 of the housing 7, each projecting into a guide groove 18 of the locking tabs 8, and effected by means of a threaded spindle which includes a threaded bolt 19 and a head 20 , A tool can be attached to the head to rotate the threaded spindle. The head 20 of the threaded spindle is rotatable in a passage opening of a cable-side part of the housing 7, but mounted fixed by means of a C-ring 21 in the axial direction. The threaded bolt 19 passes through a passage opening of the bridge 9 of the locking bracket 6, wherein an external thread of the threaded bolt 19 with an internal thread of the passage opening is engaged. The head 20 opposite the end of the threaded bolt 19 is thread-free and rotatably mounted in an opening of a bearing plate 22 held in the housing 7. To move the locking bracket 6, the threaded spindle is rotated by a tool in a clockwise direction, wherein the rotation of the threaded bolt 19 by the threaded engagement with the locking bracket 6 in a translation of the locking bracket 6 relative to the housing 7 (and the contact elements arranged therein) of the first connector. 1 leads.

Ein elektrisch leitender Kontakt zwischen den Hochstromkontaktelementen 4, 5 des ersten 1 und des zweiten Steckverbinders 2 liegt bereits in einer ersten Kontaktstellung der Steckverbindung vor. Diese erste Kontaktstellung liegt (bezogen auf die Relativbewegung der beiden Steckverbinder 1, 2) noch vor einer in der Fig. 3 dargestellten zweiten Kontaktstellung und insbesondere ca. mittig zwischen den beiden in den Fig. 2 und 5 dargestellten Relativpositionen der beiden Steckverbinder 1, 2.An electrically conductive contact between the high current contact elements 4, 5 of the first 1 and the second connector 2 is already in a first contact position the connector before. This first contact position is (relative to the relative movement of the two connectors 1, 2) before a in the Fig. 3 illustrated second contact position and in particular approximately midway between the two in the Fig. 2 and 5 shown relative positions of the two connectors 1, 2.

Obwohl ein Kontakt zwischen den Hochstromkontaktelementen 4, 5 der beiden Steckverbinder 1, 2 bereits in der ersten Kontaktstellung erreicht wird, ist für eine Funktion der Steckverbindung noch ein Zusammenstecken der beiden Steckverbinder 1, 2 bis zu der in der Fig. 5 dargestellten zweiten Kontaktstellung erforderlich. Hierzu wird die Gewindespindel weiter im Uhrzeigersinn rotiert. In der zweiten Kontaktstellung kontaktieren sich die Hochstromkontaktelemente 4, 5 weiterhin, wobei zusätzlich noch (Niederspannungs-)Kontaktelemente 23 eines Niederspannungs-Sicherungsstromkreises miteinander kontaktiert werden. Diese Niederspannungskontaktelemente 23 berühren sich in der ersten Kontaktstellung noch nicht. Der Sicherungsstromkreis dient dazu, eine Beaufschlagung der Hochstromleitungen 3 mit einer Hochspannung nur dann zu ermöglichen, wenn die Hochstromkontaktelemente 4, 5 sicher kontaktieren. Dies ist immer der Fall, wenn auch die Niederspannungskontaktelemente 23 kontaktieren. Ein Zusammenstecken bzw. Lösen der Steckverbindung unter Hochspannung kann demnach verhindert werden. Dadurch wird sowohl die Sicherheit für das die Steckverbindung handhabende Montagepersonal erhöht als auch eine Beschädigung der Steckverbindung infolge eines elektrischen Überschlags verhindert.Although a contact between the high-current contact elements 4, 5 of the two connectors 1, 2 is already achieved in the first contact position, is still a mating of the two connectors 1, 2 to the function in the Fig. 5 shown second contact position required. For this purpose, the threaded spindle is rotated further in a clockwise direction. In the second contact position, the high-current contact elements 4, 5 continue to contact, wherein additionally (low-voltage) contact elements 23 of a low-voltage fuse circuit are contacted with each other. These low-voltage contact elements 23 do not touch each other in the first contact position. The fuse circuit serves to allow the high current lines 3 to be acted upon by a high voltage only when the high current contact elements 4, 5 contact safely. This is always the case, even if the low-voltage contact elements 23 contact. A mating or releasing the connector under high voltage can be prevented accordingly. As a result, both the security for the connector handling assembly personnel is increased and prevents damage to the connector due to electrical flashover.

In der zweiten Kontaktstellung sorgen die Führungsvorsprünge 17 durch einen die Führungsnut 18 überragenden Randbereich dafür, dass die Verriegelungslaschen 8 nicht seitlich ausgelenkt werden können. Es besteht somit keine Möglichkeit, die Steckverbindung durch ein manuelles Auslenken der Verriegelungslaschen 8 und das Aufbringen einer Zugbelastung auf die beiden Steckverbinder 1, 2 zu lösen.In the second contact position, the guide projections 17 ensure that the locking tabs 8 can not be deflected laterally by means of an edge region projecting beyond the guide groove 18. There is thus no way to solve the connector by a manual deflection of the locking tabs 8 and the application of a tensile load on the two connectors 1, 2.

Vielmehr muss, um die Steckverbindung wieder zu lösen, die Gewindespindel mittels des Werkzeugs entgegen dem Uhrzeigersinn rotiert werden. Dadurch wird der Verriegelungsbügel 6 in Richtung des zweiten Steckverbinders 2 bewegt, wodurch dieser aus dem ersten Steckverbinder 1 herausgeschoben wird. Dabei erfolgt zunächst ein Lösen der Niederspannungskontaktelemente 23 des Sicherheitsstromkreises und dann - beim Überfahren der ersten Kontaktstellung - der Hochstromkontaktelemente 4, 5. Die Lösebewegung zwischen den beiden Steckverbindern 1, 2 wird mittels der Gewindespindel bis zum Erreichen der Verriegelungsstellung (vgl. Fig. 2) bewirkt. Dann wurde die Brücke 9 des Verriegelungsbügels 6 soweit auf dem Gewindebolzen verschoben, dass das Außengewinde des Gewindebolzens 19 und das Innengewinde der Brücke 9 nicht mehr ineinandergreifen. Für ein vollständiges Lösen der beiden Steckverbinder müssen diese dann auf Zug belastet werden, wodurch der Verriegelungsbügel 6 auf dem Gehäuse 7 des ersten Steckverbinders 1 weiter in Richtung des zweiten Steckverbinders 2 verschoben wird. Dabei gleiten Schrägflächen 24 der Verriegelungslaschen 8 auf Schrägflächen 25 des Gehäuses 7 ab. Dies führt zu einem seitlichen Auslenken der Verriegelungslaschen 8, wodurch die Verriegelungsvorsprünge 11 des zweiten Steckverbinders 2 freigegeben werden (vgl. Fig. 6).Rather, in order to release the connector again, the threaded spindle must be rotated by means of the tool counterclockwise. As a result, the locking bracket 6 is moved in the direction of the second connector 2, whereby it is pushed out of the first connector 1. At first, the low-voltage contact elements 23 of the safety circuit are released and then - when driving over the first contact position - the high-current contact elements 4, 5. The release movement between the two connectors 1, 2 is by means of the threaded spindle until reaching the locking position (see. Fig. 2 ) causes. Then the bridge 9 of the locking bracket 6 has been moved so far on the threaded bolt that the external thread of the threaded bolt 19 and the internal thread of the bridge 9 no longer intermesh. For a complete release of the two connectors they must then be charged to train, whereby the locking bracket 6 is moved on the housing 7 of the first connector 1 further in the direction of the second connector 2. In this case slide inclined surfaces 24 of the locking tabs 8 on inclined surfaces 25 of the housing 7 from. This leads to a lateral deflection of the locking tabs 8, whereby the locking projections 11 of the second connector 2 are released (see. Fig. 6 ).

Die Verschiebung des Verriegelungsbügels 6 relativ zu dem Gehäuse 7 von der in der Fig. 2 dargestellten Verriegelungsstellung in die in der Fig. 6 dargestellte Lösestellung führt zu einer Stauchung einer auf einem gewindefreien Abschnitt des Gewindebolzens 19 angeordneten Feder 26, die dadurch weiter vorgespannt wird. Durch die Vorspannung der Feder 26 wird erreicht, dass sich der Verriegelungsbügel 6 nach dem Freigeben der Verriegelungsvorsprünge 11 selbsttätig wieder in die in den Fig. 1 und 2 dargestellte Stellung zurück bewegt. Diese Stellung erlaubt einen erneuten Eingriff des Außengewindes des Gewindebolzens 19 in das Innengewinde der Brücke 9 des Verriegelungsbügels 6. Die Steckverbinder sind somit für ein erneutes Zusammenstecken bereit.The displacement of the locking bracket 6 relative to the housing 7 from that in the Fig. 2 illustrated locking position in the in the Fig. 6 shown release position leads to a compression of a arranged on a thread-free portion of the threaded bolt 19 spring 26, which is further biased thereby. By the bias of the spring 26 is achieved that the locking bracket 6 automatically after the release of the locking projections 11 back into the in the Fig. 1 and 2 shown position moves back. This position allows a renewed engagement of the external thread of the threaded bolt 19 in the internal thread of the bridge 9 of the locking bracket 6. The connectors are thus ready for re-mating.

Der erste Steckverbinder 1 umfasst ein Dichtelement 27, das dazu dient, die Kontaktelemente der Steckverbinder 1, 2 zumindest in den Kontaktstellungen der Steckverbindung gegenüber der Umgebung abzudichten. Das Dichtelement 27 wird hierzu in einem in den Kontaktstellungen der Steckverbindung von den Steckverbindern 1, 2 ausgebildeten Ringraum deformiert. In der Verriegelungsstellung (vgl. Fig. 2) steht das Dichtelement 27 dagegen noch außer Kontakt mit dem Gehäuse 12 des zweiten Steckverbinders 2.The first connector 1 comprises a sealing element 27, which serves to seal the contact elements of the connector 1, 2, at least in the contact positions of the connector relative to the environment. For this purpose, the sealing element 27 is deformed in an annular space formed by the connectors 1, 2 in the contact positions of the plug connection. In the locking position (see. Fig. 2 On the other hand, the sealing element 27 is still out of contact with the housing 12 of the second connector 2.
