Description

Stand der TechnikState of the art

Die Erfindung betrifft ein Kontaktsystem. Das Kontaktsystem weist wenigstens einen Stecker und wenigstens einen Gegenstecker auf. Der Stecker weist wenigstens einen elektrisch leitfähigen Kontakt auf und der Gegenstecker weist wenigstens einen elektrisch leitfähigen Gegenkontakt auf. Der Kontakt und der Gegenkontakt sind jeweils ausgebildet, miteinander insbesondere trennbar steckverbunden zu werden.The invention relates to a contact system. The contact system has at least one plug and at least one mating connector. The plug has at least one electrically conductive contact and the mating plug has at least one electrically conductive mating contact. The contact and the mating contact are each designed to be plugged into each other in particular separable.

Bei aus dem Stand der Technik bekannten Kontaktsystemen, welche eine Steckverbindung umfassen, insbesondere Hochvolt-Steckverbindungen bei Elektrofahrzeugen oder bei Hybridfahrzeugen, besteht das Problem, dass zu Wartungsarbeiten der Stecker von dem Gegenstecker getrennt werden muss, was mit einem Sicherheitsrisiko wegen einer an dem Kontaktsystem möglicherweise noch anliegenden Hochspannung, insbesondere zwischen 400 Volt und 1000 Volt verbunden ist.In known from the prior art contact systems, which include a connector, especially high-voltage connectors in electric vehicles or hybrid vehicles, there is the problem that for maintenance of the plug must be disconnected from the mating connector, which may be a security risk because of a contact system still connected high voltage, in particular between 400 volts and 1000 volts is connected.

Bei bisher bekannten Schraubklemmenverbindungen, bei denen ein Kabelschuh mit einer Schraubklemme verschraubt werden kann, besteht jedoch kein ausreichender Berührungsschutz, insbesondere wenn Reparaturversuche durch unautorisierte Personen durchgeführt werden.In previously known Schraubklemmenverbindungen in which a cable lug can be screwed to a screw, however, there is no sufficient protection against contact, especially when repair attempts are carried out by unauthorized persons.

Aus der DE 10 2010 050124 B3 ist eine Stromverteilereinrichtung für ein Hochspannungsnetz in einem Kraftfahrzeug bekannt, bei dem nach einem Schließen einer Verriegelungseinrichtung ein in einen Anschluss eingesteckter Stecker nicht mehr abziehbar ist.From the DE 10 2010 050124 B3 a power distribution device for a high-voltage network in a motor vehicle is known in which after closing a locking device plugged into a connector plug is no longer removable.

Aus der US 7 104 830 B1 ist eine elektrische Verbindung bekannt, bei der eine Verriegelungsvorrichtung vorgesehen ist, die ein versehentliches Herausziehen eines Steckers aus der Verbindung verhindern kann.From the US Pat. No. 7,104,830 B1 an electrical connection is known in which a locking device is provided which can prevent accidental withdrawal of a plug from the connection.

Offenbarung der ErfindungDisclosure of the invention

Erfindungsgemäß weist der Stecker des Kontaktsystems der eingangs genannten Art ein Steckergehäuse auf. Das Steckergehäuse weist einen Steckerkragen auf. Weiter weist das Kontaktsystem ein Verriegelungselement auf, wobei das Verriegelungselement ausgebildet ist, entlang einer Translationsachse auf den Steckerkragen geschoben zu werden und den Stecker gegen ein Lösen von dem Gegenstecker zu sichern. Der Gegenstecker weist bevorzugt wenigstens einen sich mit wenigstens einer Richtungskomponente oder in Richtung der flachen Erstreckung des Steckerkragens erstreckenden Vorsprungsbereich auf, welcher angeordnet und ausgebildet ist, das Verriegelungselement wenigstens teilweise zu umgreifen oder zu hintergreifen und gegen den Steckerkragen zu halten.According to the invention, the plug of the contact system of the aforementioned type has a plug housing. The plug housing has a plug collar. Furthermore, the contact system has a locking element, wherein the locking element is designed to be pushed along a translation axis on the plug collar and to secure the plug against detachment from the mating connector. The mating connector preferably has at least one projection region extending with at least one directional component or in the direction of the flat extension of the connector collar, which is arranged and configured to at least partially surround or engage behind the locking element and hold it against the connector collar.

Bevorzugt ist der Steckerkragen um eine Steckachse des Steckers umlaufend ausgebildet.Preferably, the plug collar is formed circumferentially around a plug-in axis of the plug.

Mittels des so ausgebildeten Verriegelungselements kann der Stecker vorteilhaft mit dem Gegenstecker verriegelt werden. Die Verriegelung kann beispielsweise mittels eines Plombendrahtes zusätzlich gesichert werden, sodass ein unbefugtes Öffnen des Kontaktsystems von außen leicht erkannt werden kann.By means of the thus formed locking element, the plug can be advantageously locked with the mating connector. The lock can be additionally secured, for example by means of a sealing wire, so that unauthorized opening of the contact system can be easily detected from the outside.

In einer bevorzugten Ausführungsform ist das Verriegelungselement ausgebildet, den Steckerkragen gegen den Gegenstecker zu pressen oder federnd anzudrücken. Das Verriegelungselement kann dazu beispielsweise entlang einer ebenen Erstreckung keilförmig ausgebildet sein, sodass beim Einschieben und Verriegeln eine Presswirkung durch ein Abstützen gegen den Vorsprungsbereich erzeugt werden kann. Das Verriegelungselement kann beispielsweise zum federnden Anpressen eine gewölbte Blattfeder aufweisen, welche ausgebildet und angeordnet ist, beim Aufschieben des Verriegelungselements auf den Steckerkragen gegen den wenigstens einen Vorsprungsbereich federnd abzustützen. Dadurch kann der Stecker sicher mit dem Gegenstecker verbunden werden und die Kontakte von auf das Kontaktsystem einwirkenden Vibrationen entlastet werden.In a preferred embodiment, the locking element is designed to press the plug collar against the mating connector or resiliently. For this purpose, the locking element may be designed, for example, wedge-shaped along a planar extension, so that a pressing action can be generated by being supported against the projecting area during insertion and locking. The locking element may, for example, for resilient pressing have a curved leaf spring, which is designed and arranged to resiliently support the sliding of the locking element on the plug collar against the at least one projection region. Thereby, the plug can be securely connected to the mating connector and the contacts are relieved of acting on the contact system vibrations.

Der Vorsprungsbereich ist beispielsweise durch eine abgewinkelte Schiene gebildet, welche mit dem Gegenstecker verbunden ist und ein sich parallel zum Steckerkragen, dem Steckerkragen entgegenstreckender Schenkel den Vorsprungsbereich bildet. Bevorzugt sind der Schenkel und der Steckerkragen einander überlappungsfrei angeordnet, so dass der Stecker quer zu einer Erstreckung des Vorsprungsbereiches abgezogen werden kann. Das Verriegelungselement weist beispielsweise einen sich entlang einer Längsachse erstreckenen Blechstreifen auf, welcher in einer den Stecker verriegelnden Position mit einem sich quer zur Längsachse erstreckenden Querabschnitt auf dem Steckerkragen aufliegt und mit einem dazu benachbarten Querabschnitt in eine von dem Schenkel gebildete Nut eingreift und so den Steckerkragen an dem Schenkel abstützend gegen ein Abziehen des Steckers sichern kann.

Der Blechstreifen ist beispielsweise durch Edelstahl 1.4310 gebildet.The contact system 1 also has a locking element 8. The locking element 8 is formed in this embodiment as along the translation axis 10 of the longitudinally extending metal strip, in particular sheet steel strips. The metal strip has, for example, a thickness between 0.6 and 1.5 millimeters. The metal strip is formed for example by stainless steel 1.4310.

Das Verriegelungselement 8 weist einen - in Figur 3 näher dargestellten - Durchbruch 32 auf, welcher derart geformt und ausgebildet ist, dass der Verriegelungsstift 11 durch den Durchbruch 32 mit einem Endabschnitt 77 hindurchgeführt werden kann. Das Verriegelungselement 8 weist auch einen Durchbruch 33 auf, welcher derart ausgebildet ist, dass der Verriegelungsstift 12 durch den Durchbruch 33 mit einem Endabschnitt hindurchgeführt werden kann.The locking element 8 has a - in FIG. 3 illustrated breakthrough 32, which is shaped and formed such that the locking pin 11 can be passed through the opening 32 with an end portion 77. The locking element 8 also has an opening 33, which is formed such that the locking pin 12 can be passed through the opening 33 with an end portion.

An den Durchbruch 32 schließt eine in dem Verriegelungselement 8 als Langloch ausgebildeter Durchbruchbereich 16 an. Der Durchbruchbereich 16 weist einen Durchbruchrand 35 auf, welcher ausgebildet ist, von einem Vorsprungsbereich 19 des Verriegelungsstiftes 11 formschlüssig umgriffen zu werden. Der Vorsprungsbereich 19 ist auf dem Endabschnitt 77 des Verriegelungsstiftes 11 ausgebildet. Der Verriegelungsstift 11 weist auch eine Nut 18 auf, welche entlang einer Längserstreckung des Verriegelungsstiftes 11 an den sich quer zur Längserstreckung erstreckenden Vorsprung 19 anschließt.At the opening 32 includes a formed in the locking member 8 as a slot breakthrough area 16 at. The breakthrough region 16 has a breakthrough edge 35 which is designed to be encompassed by a projection region 19 of the locking pin 11 in a form-fitting manner. The protruding portion 19 is formed on the end portion 77 of the locking pin 11.

Der Verriegelungsstift 12 weist auf dem zum Durchführen durch den Durchbruch 33 des Verriegelungselements 8 ausgebildeten Endabschnitt auf, wobei in dem Endabschnitt eine Nut 20 ausgebildet ist, an die zum Ende des Verriegelungsstiftes 12 hin ein sich quer zur Längserstreckung des Verriegelungsstiftes 12 erstreckender Vorsprung 21 anschließt.The locking pin 12 has on the trained for passing through the opening 33 of the locking member 8 end portion, wherein in the end portion, a groove 20 is formed, to the end of the locking pin 12 out a transversely to the longitudinal extension of the locking pin 12 extending projection 21 connects.

Der Durchbruch 33 schließt an einen langlochförmig ausgebildeten Durchbruchsbereich 17 an, wobei sich eine Längserstreckung des Langlochs in Richtung der Translationsachse 10 erstreckt.The opening 33 adjoins an elongate hole-shaped opening region 17, wherein a longitudinal extension of the elongated hole extends in the direction of the translation axis 10.

Wenn das Verriegelungselement 8 entlang seiner Längserstreckung translatorisch entlang der Translationsachse 10 bewegt wird, so kann der Durchbruchrand 35 des langlochförmigen Durchbruchs 16 von der Nut 18 des Verriegelungsstiftes 11 geführt werden. Der Durchbruchrand 35 im Bereich des langlochförmigen Durchbruchs 16 kann dann die Nut 18 eingreifen und so von dem Vorsprung 19 umgriffen werden. Der Verriegelungsstift 11 wird somit durch das Verschieben des Verriegelungselements 8 entlang der Translationsachse 10 in den langlochförmigen Durchbruch 16 hineinbewegt.When the locking element 8 is moved translationally along the translation axis 10 along its longitudinal extension, the breakthrough edge 35 of the slot-shaped opening 16 can be guided by the groove 18 of the locking pin 11. The breakthrough edge 35 in the region of the slot-shaped opening 16 can then engage the groove 18 and thus be encompassed by the projection 19. The locking pin 11 is thus moved by the displacement of the locking element 8 along the translation axis 10 in the slot-shaped opening 16.

Der Verriegelungsstift 12 kann - wie der Verriegelungsstift 11 - beim Bewegen des Verriegelungselements 8 den Durchbruchrand 36 im Bereich des langlochförmigen Durchbruchs 16 umgreifen.The locking pin 12 can - as the locking pin 11 - engage around the breakthrough edge 36 in the region of the slot-shaped opening 16 when moving the locking element 8.

Das Verriegelungselement 8 ist ausgebildet und angeordnet, den Steckerkragen 7 zwischen dem Verriegelungselement 8 und dem Gegenstecker 5, insbesondere der Platte 15 des Gegensteckers 5, einzuschließen. Das Verriegelungselement 8 kann so auf dem Steckerkragen 7 entlang der Translationsachse 10 hin- und hergeschoben werden. Der Gegenstecker ist beispielsweise aus Kunststoff oder Metall, insbesondere Aluminium gebildet.The locking element 8 is formed and arranged to include the plug collar 7 between the locking element 8 and the mating connector 5, in particular the plate 15 of the mating connector 5. The locking element 8 can thus be pushed back and forth on the plug collar 7 along the translation axis 10. The mating connector is formed for example of plastic or metal, in particular aluminum.

Der Steckerkragen 7 weist in diesem Ausführungsbeispiel eine Ausnehmung für den Verriegelungsstift 11 und eine weitere Ausnehmung für den Verriegelungsstift 12 auf. Die Verriegelungsstifte 11 und 12 können so beim Aufstecken des Steckergehäuses 3, an das der Steckerkragen 7 angeformt ist, entlang der Steckachse 78, durch die entsprechenden Ausnehmungen in dem Steckerkragen 7 hindurchgeführt werden.The plug collar 7 has in this embodiment, a recess for the locking pin 11 and a further recess for the locking pin 12. The locking pins 11 and 12 can thus be passed through the corresponding recesses in the plug collar 7 when plug housing 3, to which the plug collar 7 is formed, along the through-axle 78.

Das Verriegelungselement 8 weist in diesem Ausführungsbeispiel auch eine Rastnase 22 auf, welche einen Endabschnitt des Verriegelungselements 8 bildet. Bei einem Verschieben des Verriegelungselements 8 kann so die Rastnase 22 in einer Verriegelungsstellung des Verriegelungselements 8 in eine in dem Steckerkragen 7 ausgebildete Aussparung 34 federnd eingreifen, sodass das Verriegelungselement 8 gegen ein Zurückbewegen entlang der Längsachse gesichert ist.In this exemplary embodiment, the locking element 8 also has a latching nose 22, which forms an end section of the locking element 8. Upon a displacement of the locking element 8, the latching lug 22 can thus engage in a locking position of the locking element 8 in a formed in the plug collar 7 recess 34 resiliently engage, so that the locking element 8 is secured against being moved back along the longitudinal axis.

Das Verriegelungselement 8 weist den abgewinkelten Endabschnitt 23 auf, welcher dem als Rastnase 22 ausgebildeten Endabschnitt gegenüberliegt. Das Verriegelungselement 8 ist ausgebildet, an dem abgewinkelten Endabschnitt 23 gegriffen oder hintergriffen zu werden und so entlang der Translationsachse 10 zwischen einer verriegelten Stellung und einer offenen Stellung hin- und hergeschoben zu werden.The locking element 8 has the angled end portion 23 which faces the end portion formed as a latching nose 22. The locking member 8 is adapted to be gripped or engaged behind the angled end portion 23 and thus reciprocated along the translation axis 10 between a locked position and an open position.

Die Verriegelungsstifte 11 und 12 können so in der offenen Stellung durch den jeweiligen Durchbruch 32 beziehungsweise 33 hindurchgeführt werden, sodass der Stecker 2 entlang der Steckachse 78 von dem Gegenstecker 5 getrennt werden kann.The locking pins 11 and 12 can thus be passed in the open position through the respective opening 32 or 33, so that the plug 2 can be separated along the axle 78 from the mating connector 5.

An das Steckergehäuse 3 ist in diesem Ausführungsbeispiel ein Abdeckelement 25 angeformt, welches von dem Steckergehäuse 3 parallel zu dem Steckerkragen 7 abweist und das Verriegelungselement 8 zwischen dem Abdeckelement 25 und dem Steckerkragen 7 einschließt.On the plug housing 3, a cover 25 is formed in this embodiment, which is parallel to the plug collar 7 away from the connector housing 3 and the locking element 8 between the cover 25 and the plug collar 7 includes.

Das Steckergehäuse 3 weist auch ein Abdeckelement 26 auf, welches sich wie das Abdeckelement 25 parallel zu dem Steckerkragen 7 erstreckt.The plug housing 3 also has a cover element 26 which, like the cover element 25, extends parallel to the plug collar 7.

Die Abdeckelemente 25 und 26 sind jeweils angeordnet, den Verriegelungsstift 11 beziehungsweise den Verriegelungsstift 12 im zusammengesteckten Zustand des Steckers 2 mit dem Gegenstecker 5 abzudecken. So kann vorteilhaft mittels der Abdeckelemente 25 und 26 ein Aufbohrschutz gebildet sein, sodass die Verriegelungsstifte 11 und 12, insbesondere die Endabschnitte mit den Vorsprüngen 19 und 21, nicht weggebohrt, weggefräst oder weggeschlagen werden können und so der Stecker 2 von nicht autorisierten Personen von dem Gegenstecker 5 gelöst werden kann.The cover elements 25 and 26 are each arranged to cover the locking pin 11 and the locking pin 12 in the assembled state of the plug 2 with the mating connector 5. Thus, advantageously, by means of the cover members 25 and 26 a Aufbohrschutz be formed so that the locking pins 11 and 12, in particular the end portions with the projections 19 and 21, not weggebohrt, weggefräst or can be beaten off and so the connector 2 of unauthorized persons of the Mating connector 5 can be solved.

Das in Figur 1 dargestellte Kontaktsystem 1 weist in einer anderen Ausführungsform keine Abdeckelemente 25 und 26 auf.This in FIG. 1 illustrated contact system 1, in another embodiment, no cover elements 25 and 26.

Der abgewinkelte Endabschnitt 23 des Verriegelungselements 8 weist in diesem Ausführungsbeispiel einen Durchbruch 24 zum Durchführen eines Plombendrahtes auf.The angled end portion 23 of the locking element 8 has in this embodiment, an opening 24 for performing a seal wire.

Das Verriegelungselement 8 weist in diesem Ausführungsbeispiel auch eine Blattfeder 30 und eine Blattfeder 31 auf, welche jeweils in dem Verriegelungselement 8 ausgeformt sind. Die Blattfeder 30 ist in diesem Ausführungsbeispiel trapezförmig oder bogenförmig auf einem Längsabschnitt entlang der Translationsachse 10 des Verriegelungselements ausgebildet, wobei der Längsabschnitt wenigstens einen Teil des Langlochs 16 einschließt.The locking element 8 has in this embodiment, a leaf spring 30 and a leaf spring 31, which are each formed in the locking element 8. The leaf spring 30 is formed in this embodiment, trapezoidal or arcuate on a longitudinal portion along the translation axis 10 of the locking element, wherein the longitudinal portion includes at least a portion of the elongated hole 16.

Die Blattfeder 31, welche wie die Blattfeder 30 trapezförmig oder bogenförmig ausgebildet ist, erstreckt sich auf einem Längsabschnitt des Verriegelungselements 8, welcher den zuvor beschriebenen langlochförmigen Durchbruchbereich 16 umfasst.The leaf spring 31, which is formed like the leaf spring 30 trapezoidal or arcuate, extends on a longitudinal portion of the locking element 8, which includes the slot-shaped breakthrough region 16 described above.

So kann beim Schieben des Verriegelungselements 8 in eine Verriegelungsposition der Vorsprung 19 entlang der Längserstreckung des Verriegelungselements 8 über eine Schräge der trapezförmigen Blattfeder gleiten, sodass der Durchbruchrand 35 sich beim Geführtwerden in der Nut 18 gegen den Vorsprung 19 federnd abstützen kann. So kann das Steckergehäuse 3, insbesondere der Steckerkragen 7, von den Blattfedern 30 und 31 des Verriegelungselements 8 während eines Verschiebens des Verriegelungselements 8 in die Verriegelungsposition federnd an den Gegenstecker 5, in diesem Ausführungsbeispiel gegen die Platte 15 des Gegensteckers 5, gepresst werden.Thus, when pushing the locking element 8 in a locking position, the projection 19 along the longitudinal extension of the locking member 8 slide over a slope of the trapezoidal leaf spring, so that the breakthrough edge 35 can be resiliently supported in the groove 18 against the projection 19 when Guided. Thus, the plug housing 3, in particular the plug collar 7, of the leaf springs 30 and 31 of the locking element 8 during displacement of the locking element 8 in the locking position resiliently against the mating connector 5, in this embodiment against the plate 15 of the mating connector 5, are pressed.

Das Kontaktsystem 1 kann eine - in Figur 1 nicht dargestellte - elastisch ausgebildete Dichtung aufweisen, welche zwischen dem Steckerkragen 7 und dem Gegenstecker 5 angeordnet und ausgebildet ist, den Stecker und den Gegenstecker einander abzudichten.The contact system 1 may have a - in FIG. 1 not shown - have elastically formed seal which between the plug collar 7 and the Mating connector 5 is arranged and designed to seal the plug and the mating connector each other.
