Description

Die vorliegende Erfindung betrifft einen Stecker gemäß dem Oberbegriff von Anspruch 1 sowie eine elektrische Steckverbindung gemäß Anspruch 9.The present invention relates to a plug according to the preamble of claim 1 and an electrical connector according to claim 9.

Im Stand der Technik sind unterschiedliche elektrische Steckverbinderkonzepte bekannt, bei denen in der Regel ein männlicher Steckverbinder (Stecker) mit einem weiblichen Steckverbinder (Buchse) in elektrisch und mechanische Verbindung gebracht wird.In the prior art, different electrical connector concepts are known in which usually a male connector (plug) with a female connector (socket) is brought into electrical and mechanical connection.

Je nach Anwendungsfall müssen die Steckverbinderpaare, somit der Stecker und/oder die Buchse gewissen Anforderungen genügen, insbesondere auch Anforderungen an Umwelteinflüsse.Depending on the application, the connector pairs, thus the plug and / or the socket must meet certain requirements, in particular requirements for environmental influences.

Ein wesentliches Merkmal welches bei Steckverbindern, insbesondere bei mehrpoligen Steckverbindern, auftritt und insbesondere auch bei geschirmten Steckverbindern im Einsatz von schmutziger Umgebung ist, sind Vorrichtungen, welche Schmutz von den Steckverbinderpaaren abhalten. Beim Einsatz in schmutziger Umgebung werden daher unterschiedliche Dichtkonzepte verwendet, so dass die Kontaktkammern oder der Innenraum eines Steckverbinders von Schmutz oder Schmutzpartikeln frei bleiben.An essential feature which occurs in connectors, especially in multi-pin connectors, and in particular in shielded connectors in the use of dirty environment, are devices that prevent dirt from the connector pairs. When used in dirty environment therefore different sealing concepts are used so that the contact chambers or the interior of a connector of dirt or dirt particles remain free.

In der Regel wird zwischen den Stecker und der Buchse eine Dichtebene und eine Dichtung angebracht, so dass beim Zusammenstecken der Steckverbinderpaare der eine Steckverbinder mit seiner Dichtebene auf die Dichtung des korrespondierenden Steckers (Buchse) aufliegt und mittels einer Verriegelung den Stecker dicht mit der Buchse verbindet. Solche gedichteten Steckverbinder werden je nach Grad der Dichtigkeit in EP-Schutzklassen eingeteilt.In general, a sealing plane and a seal is mounted between the plug and the socket, so that when mating the connector pairs of a connector with its sealing level on the seal of the corresponding plug (socket) rests and connects by means of a lock the plug tight with the socket , Such sealed connectors are classified according to the degree of tightness in EP protection classes.

Allerdings besteht zunehmend das Bedürfnis, die Steckverbinder nicht nur im gesteckten und/oder verriegelten Zustand gegenüber Umwelteinflüssen wie Schmutz, Staub oder sonstige störende Partikel abzudichten, sondern auch im nicht gesteckten, somit geöffneten Zustand.However, there is an increasing need to seal the connector not only in the plugged and / or locked state against environmental influences such as dirt, dust or other disturbing particles, but also in the unplugged, thus opened state.

Es besteht also im Stand der Technik das Bedürfnis, Steckverbinder so weiter zu entwickeln, dass diese auch im nicht gesteckten Zustand vor Schmutz geschützt bleiben.There is therefore a need in the prior art to develop connectors so that they remain protected from dirt even when not plugged.

Die Druckschrift EP 0 615 312 A2 zeigt einen Steckverbinder, mit einer im Steckverbinder hin- und her bewegbaren Schutzvorrichtung, die allerdings den Nachteil hat, dass durch Öffnungen in der Schutzvorrichtung Schmutz in den Kontaktaufnahmeraum gelangen kann.The publication EP 0 615 312 A2 shows a connector, with a back and forth in the connector protective device, however, has the disadvantage that can get through openings in the protection dirt in the contact receiving space.

Die Druckschrift US 2010/0233895 A1 zeigt eine alternative Ausführungsform, um Kontakte vor Schmutz im nicht gesteckten Zustand zu schützen. Allerdings ist hierbei nachteilig, dass der Steckverbinder komplex aufgebaut ist, keine kompakte Bauform aufweist und insbesondere Verschleißelemente vorhanden sind, die ihre Funktion nach und nach verlieren können oder jedenfalls selbst Abrieb zu erzeugen, der in den Aufnahmeraum gelangen kann.The publication US 2010/0233895 A1 shows an alternative embodiment to protect contacts from dirt in the unplugged state. However, this is disadvantageous in that the connector is complex, has no compact design and in particular wear elements are present, which can gradually lose their function or at least even produce abrasion, which can get into the receiving space.

Werden ungeschützte Steckverbinder eingesetzt, so kommt es in der Praxis häufig zu dem Fall, dass mit einem Werkzeug oder mit Hilfsmitteln Schmutz aus dem Steckverbinderaufnahmeraum oder dem Raum, in dem sich die Kontakte befinden, mittels dieser Werkzeuge beseitigt wird.If unprotected connectors are used, in practice it is frequently the case that dirt is removed from the connector receiving space or the space in which the contacts are located by means of these tools with tools or auxiliary means.

Hierbei werden die Kontakte beschädigt und der Steckverbinder ist nicht mehr funktionsfähig.In this case, the contacts are damaged and the connector is no longer functional.

Darüber hinaus kann es zu weiteren Ausfällen oder Störungen kommen, wenn Schmutz in den Steckverbinderinnenraum gelangt.In addition, further failures or malfunctions may occur if dirt gets into the connector interior.

Aufgabe der vorliegenden Erfindung ist es daher, einen Steckverbinder bereitzustellen, der vorbesagte Nachteile nicht aufweist und sowohl im gesteckten als auch im nicht gesteckten Zustand ausreichend Schutz gegen Schmutz oder Schmutzpartikel bietet.The object of the present invention is therefore to provide a connector which does not have the aforementioned disadvantages and offers sufficient protection against dirt or dirt particles both when plugged in and when not plugged in.

Diese Aufgabe wird gelöst mit einem Stecker mit den Merkmalen gemäß Anspruch 1 und einer Steckverbindung mit den Merkmalen gemäß Anspruch 11.This object is achieved with a plug having the features according to claim 1 and a plug connection with the features according to claim 11.

Die Aufgabe der vorliegenden Erfindung wird gelöst durch eine Schutzvorrichtung, die entweder im Stecker oder der Buchse hin- und her bewegbar im Kontaktaufnahmeraum angeordnet ist und dabei die Kontakte, jedenfalls teilweise so umgibt, dass die Kontakte sowie der Kontaktaufnahmeraum gegen Schmutz geschützt sind und zwar sowohl im nicht gesteckten als auch im gesteckten Zustand.The object of the present invention is achieved by a protective device, which is arranged either in the plug or the socket back and forth movable in the contact receiving space while the contacts, at least partially so surrounds that the contacts and the contact receiving space are protected against dirt and both in the unplugged as well as in the mated condition.

Dies wird dadurch bewerkstelligt, dass die im Kontaktaufnahmeraum angeordnete Schutzvorrichtung in dieser beweglich und zwar hin- und her bewegbar angeordnet ist.This is accomplished by arranging the protective device arranged in the contact receiving space in this movable and reciprocating manner.

Die Schutzvorrichtung wird im Steckergehäuse an einer Feder, vorzugsweise an einer Schraubenfeder federgelagert hin- und her bewegbar angeordnet und zwar in Steckrichtung S hin- und her bewegbar.The protective device is arranged in the connector housing to a spring, preferably spring-mounted on a coil spring back and forth movable and in the direction of insertion S back and forth movable.

Somit lässt sich die Schutzvorrichtung von einer im nicht gesteckten Zustand abdichtender Stellung in eine Stellung überführen, in dem der korrespondierende Gegenstecker, hier die Buchse, in den Stecker eingeschoben ist und diesen abdichtet.Thus, the protective device can be transferred from a non-inserted state sealing position into a position in which the corresponding mating connector, here the socket, is inserted into the plug and seals it.

Beim Übergang vom ungesteckten Zustand in den gesteckten Zustand wird die Schutzvorrichtung entgegen der Federkraft der Feder, vorzugsweise der Schraubenfeder, in den Kontaktaufnahmeraum hineingedrückt und zwar entlang von im Kontaktaufnahmeraum angeordneten Gleitlagern.During the transition from the unplugged state into the inserted state, the protective device is pressed against the spring force of the spring, preferably the helical spring, into the contact receiving space, namely along slide bearings arranged in the contact receiving space.

Die Schutzvorrichtung hat dabei ein stirnseitiges, den Kontaktaufnahmeraum abdichtendes Deckelelement, durch welches in einer vorteilhaften Ausführungsform die im Kontaktaufnahmeraum angeordneten Gleitlager hindurch tauchen können und zwar durch im Deckelelement angeordnete Öffnungen.The protective device has a frontal, the contact receiving space sealing lid member through which in an advantageous embodiment, the arranged in the contact receiving space slide bearing can dive through and arranged in the cover member openings.

Die Schutzvorrichtung weist demnach auch Kontaktdurchgangsöffnungen für die Kontakte auf, durch die die Kontakte hindurch dringen können, wenn die Schutzvorrichtung im Kontaktaufnahmeraum hin- und her bewegt wird, sozusagen betätigt wird.The protection device thus also has contact through-holes for the contacts, through which the contacts can penetrate when the protection device is moved back and forth in the contact receiving space, so to speak is actuated.

Wird daher die Schutzvorrichtung gegen die Federkraft in Steckrichtung S der Steckverbindung betätigt, in dem die Buchse in den Steckverbinder eingeführt wird, so wird die Schutzvorrichtung entlang des einen oder der mehreren angeordneten Gleitlager verschoben, wobei während des Betätigens und damit während des Verschiebens das Deckelelement mit seinen Dichtflächen sowohl den Kontaktaufnahmeraum als auch die Gleitdichtungen und vorzugsweise auch die Kontakte an ihren Außenflächen abdichtet.Therefore, if the protection device against the spring force in the insertion direction S of the connector is actuated, in which the socket is inserted into the connector, the protective device is displaced along the one or more arranged sliding bearing, wherein during the actuation and thus during the displacement of the cover member with its sealing surfaces seals both the contact receiving space and the sliding seals and preferably also the contacts on their outer surfaces.

In einer alternativen Ausführungsform können die Gleitlager auch so angeordnet sein, dass das Deckelelement bzw. die Schutzvorrichtung an dieser außen anliegend vorbei gleitet.In an alternative embodiment, the plain bearings can also be arranged so that the cover element or the protective device slides past it on the outside.

Jedenfalls ist sicher zu stellen, dass die Schutzvorrichtung über Dicht- und Gleitflächen verfügt, die sowohl die Kontakte gegenüber der Umgebung abdichten, als auch den Kontaktaufnahmeraum gegenüber der Umgebung.In any case, it must be ensured that the protective device has sealing and sliding surfaces which both seal the contacts against the environment and the contact receiving space with respect to the environment.

In einer vorteilhaften Ausführungsform ist im Bereich des Kontaktaufnahmeraums mindestens ein mit Vorteil zwei Gleitlager als Lager für das Schutzelement ausgebildet, an dem das Schutzelement gleitend hin- und her bewegbar angeordnet ist.In an advantageous embodiment, in the region of the contact receiving space, at least one advantageously two plain bearings are designed as bearings for the protective element, on which the protective element is arranged to be able to slide back and forth.

Die Kontaktdurchgangsöffnungen der Schutzvorrichtung, welche im Deckelelement ausgebildet sind, weisen ebenfalls Anlageflächen auf, so dass die Kontakte während der Betätigung des Schutzelementes von diesem an den Mantelflächen der Kontakte abgedichtet werden und zwar sowohl im ungesteckten Zustand als auch während dem Übergang vom ungesteckten in den gesteckten Zustand.The contact through openings of the protection device, which are formed in the cover member, also have contact surfaces, so that the contacts are sealed during actuation of the protective element of this on the lateral surfaces of the contacts both in the unplugged state and during the transition from the unmated to the mated Status.

Mit Vorteil wird eine im wesentlichen topfförmige Schutzvorrichtung, vorzugsweise eine der Innenkontur angepasste Form ausgebildete Schutzvorrichtung bereitgestellt, die über einen umlaufenden Mantel und ein Deckelelement verfügt.Advantageously, an essentially cup-shaped protective device, preferably a protective device designed to match the inner contour, is provided, which has a circumferential jacket and a cover element.

So wird beispielsweise bei einem Rundsteckverbinder eine zylinderförmige und einseitig offene Schutzvorrichtung bereitgestellt, bei der die der offenen Seite gegenüberliegende Seite mit dem Deckelelement verschlossen ist.Thus, for example, in the case of a circular connector, a cylindrical protection device which is open at one end is provided, in which the side opposite the open side is closed by the cover element.

Das Deckelelement weist wenigstens eine Lageröffnung für ein wenigstens erstes Gleitlager auf und zwar derart, dass das Gleitlager durch die Lageröffnung bei der Betätigung hindurch dringen kann und an dieser entlang bewegt werden kann.The cover element has at least one bearing opening for at least a first sliding bearing in such a way that the sliding bearing can penetrate through the bearing opening during actuation and can be moved along this.

Ferner sind die Innenflächen der Lageröffnungen der Schutzvorrichtung als Gleit- und Dichtflächen ausgebildet zur Abdichtung und zwar zur Abdichtung während der Betätigung der Schutzvorrichtung und zwar an den Außenflächen der Gleitlager.Furthermore, the inner surfaces of the bearing openings of the protective device are designed as sliding and sealing surfaces for sealing and that for sealing during actuation of the protective device and that on the outer surfaces of the sliding bearing.

Entsprechend der Anordnung der Gleitlager im Stecker können im korrespondierenden Gegenstecker, somit in der Buchse, Codierausnehmungen vorgesehen sein, in die die Gleitlager beim Stecken von der Steckverbindung, somit von dem Stecker und der Buchse in die Codierausnehmungen eintauchen können.According to the arrangement of the sliding bearing in the plug Codierausnehmungen can be provided in the corresponding mating connector, thus in the socket, in which the slide bearing when plugging from the connector, thus from the plug and the socket can dive into the Codierausnehmungen.

Hierdurch wird gewährleistet, dass die Gleitlager im Stecker gleichzeitig Codierrippen darstellen, die in die Codierausnehmungen der Buchse eintauchen und somit ein fehlerhaftes Stecken der Steckverbindung vermeiden.This ensures that the plain bearings in the plug simultaneously represent coding ribs that dip into the Codierausnehmungen the socket and thus avoid incorrect insertion of the connector.

In Fig. 1 ist ein Stecker 2 in perspektivischer Ansicht dargestellt. Der Stecker 2 umfasst ein Steckergehäuse 21. In diesem Ausführungsbeispiel ist der Stecker 2 als ein Rundsteckverbinder dargestellt, mit einem im wesentlichen zylinderförmigen Steckergehäuse 21.In Fig. 1 a plug 2 is shown in a perspective view. The plug 2 comprises a plug housing 21. In this embodiment, the plug 2 is shown as a circular connector, with a substantially cylindrical plug housing 21st

Wie in Fig. 4 und Fig. 5 ersichtlich, befindet sich im Steckergehäuse 21 ein Kontaktträger 22, in dem Kontakte 20 angeordnet sind, die auch mit ihren stirnseitigen Enden in Fig. 1 dargestellt sind.As in 4 and FIG. 5 can be seen, located in the connector housing 21, a contact carrier 22, in which contacts 20 are arranged, which also with their front ends in Fig. 1 are shown.

Im vorderen Bereich des Steckers 2 befindet sich ein Kontaktaufnahmeraum 25, in welche die Kontakte 20 zumindest teilweise hineinragen.In the front region of the plug 2 is a contact receiving space 25 into which the contacts 20 at least partially protrude.

Wie in Fig. 1 ferner ersichtlich ist, befindet sich im Kontaktaufnahmeraum 25 die erfindungsgemäße Schutzvorrichtung 40 eingesetzt, wie sie in Fig. 3 in einer Ober- und Unteransicht dargestellt ist.As in Fig. 1 can be seen, is located in the contact receiving space 25, the protective device 40 according to the invention used as shown in Fig. 3 is shown in a top and bottom view.

Die Fig. 3 zeigt ferner den prinzipiellen Aufbau einer erfindungsgemäßen Schutzvorrichtung 40.The Fig. 3 further shows the basic structure of a protective device 40 according to the invention.

Die Schutzvorrichtung 40 ist in dem vorliegenden Ausführungsbeispiel als eine im wesentlichen zylinder- bzw. topfförmige Schutzvorrichtung ausgebildet. Neben dem Mantel 44 befindet sich an der Oberseite in der oberen Ansicht der Fig. 3 ein Deckelelement 43, welchen den zylinderförmigen Mantel 44 an einer Seite verschließt.The protective device 40 is formed in the present embodiment as a substantially cylindrical or cup-shaped protective device. In addition to the jacket 44 is located at the top in the upper view of Fig. 3 a lid member 43 which closes the cylindrical shell 44 on one side.

Die dem Deckelelement 43 gegenüberliegende Seite ist, wie in Fig. 3 in der Unteransicht dargestellt, offen, so dass, wie zuvor beschrieben, eine topfförmige Gestalt der Schutzvorrichtung 40 geben ist. In dem Deckelelement 43 befinden sich jeweils zwei Lageröffnungen 45, für die in Fig. 1 dargestellten Gleitlager 24. Neben den Lageröffnungen 45 bzw. zwischen denen diesen angeordnet, befinden sich Kontaktdurchgangsöffnungen 42 für Kontakte 20. Diese können auch an anderen Stellen des Deckelelementes 43 und zwar an den Kontaktpositionen eines Steckers je nach Kontaktanordnung eingebracht sein.The lid member 43 opposite side is, as in Fig. 3 shown in the bottom view, so that, as described above, give a cup-shaped shape of the protective device 40 is. In the cover member 43 are each two bearing openings 45, for in Fig. 1 In addition to the bearing openings 45 and arranged between them, there are contact through openings 42 for contacts 20. These can also be introduced at other locations of the cover element 43 and that at the contact positions of a plug depending on the contact arrangement.

Die Lageröffnungen 45 verfügen über Gleit- und Dichtflächen 46, an denen die Gleitlager 24 berührend anliegen und an denen entlang die Schutzvorrichtung 40 bewegt werden kann.The bearing openings 45 have sliding and sealing surfaces 46, on which the sliding bearing 24 bear touching and along which the protective device 40 can be moved.

Fig. 2 zeigt eine Buchse 3 die steckbar mit dem Stecker 2, gemäß Fig. 1, ausgebildet ist. Fig. 2 shows a socket 3 pluggable with the plug 2, according to Fig. 1 , is trained.

Die Buchse 3 verfügt über ein Buchsengehäuse 31, in dem ein Kontaktträger 32 angeordnet ist, in dem Buchsenkontakte 30 eingebracht sind. Sowohl der Stecker 2 als auch die Buchse 3 verfügen je über einen Kabelausgang 23 bzw. 33 an der der Steckseite gegenüberliegenden Seite des Steckers 2 bzw. der Buchse 3.The socket 3 has a socket housing 31, in which a contact carrier 32 is arranged, are introduced in the socket contacts 30. Both the plug 2 and the socket 3 each have a cable outlet 23 or 33 on the opposite side of the plug side of the plug 2 and the socket third

Am Kontaktträger 32 sind Codierausnehmungen 34 angebracht.At the contact carrier 32 Codierausnehmungen 34 are attached.

Beim Zusammenstecken von Stecker 2 und Buchse 3 können die Gleitlager 24, welche in ihrer Form korrespondierend zu den Codierausnehmungen 34 ausgebildet sind, in diese eintauchen beim Zusammenstecken von Stecker 2 und Buchse 3.When plugging connector 2 and 3 socket, the sliding bearing 24, which are formed in their form corresponding to the Codierausnehmungen 34, dive into this when mating connector 2 and socket. 3

In Fig. 4 deutlich erkennbar sind die Kontakte 20, die sich in den Kontaktaufnahmeraum 25 erstrecken von der Schutzvorrichtung 40 umschlossen und dichten somit den Kontaktaufnahmeraum im nicht gesteckten Zustand ab.In Fig. 4 clearly visible, the contacts 20, which extend into the contact receiving space 25 extend from the protective device 40 and thus seal the contact receiving space in the unplugged state.

Ferner ist zu erkennen, dass die Schutzvorrichtung 40 federgelagert ist und zwar an einer Spiralfeder 41.Furthermore, it can be seen that the protective device 40 is spring-mounted, namely on a coil spring 41st

In einer vorteilhaften Ausführungsform ist die Schutzvorrichtung 40 gegen einen am Steckergehäuse 21 ausgebildeten, umlaufenden Kragen 27 federgelagert eingespannt.In an advantageous embodiment, the protective device 40 is spring-mounted clamped against a formed on the plug housing 21, circumferential collar 27.

Die Steckverbindung kann von der, wie in Fig. 4 dargestellten nicht gesteckten Position, in die in Fig. 5 dargestellte gesteckte Position übergeführt werden. Hierbei tauchen die Kontakte 20 in die Buchsenkontakte 30 ein, während sich die Schutzvorrichtung 40 entlang der Gleitlager 24 verschiebt und zwar so lange, bis die in Fig. 5 vollständig gesteckte Position erreicht ist.The plug connection may differ from that as shown in Fig. 4 shown un - inserted position in the in Fig. 5 shown plugged position transferred. In this case, the contacts 20 dive into the socket contacts 30, while the protective device 40 moves along the sliding bearing 24 and that until the in Fig. 5 fully inserted position is reached.

Hierbei ist auch ersichtlich, wie die Spiralfeder 41 nun in ihrer komprimierten Form abgebildet ist.It can also be seen how the coil spring 41 is now shown in its compressed form.

Wird der Stecker 2 und die Buchse 3, somit die Steckverbindung, wieder getrennt, somit von der in Fig. 5 dargestellten Position in eine wie in Fig. 4 dargestellt Position überführt, ist der zuvor beschriebene Prozess reversibel und läuft dementsprechend in umgekehrter Reihenfolge ab.If the plug 2 and the socket 3, thus the connector, again separated, thus from the in Fig. 5 shown position in a like in Fig. 4 shown converted position, the process described above is reversible and runs accordingly in reverse order from.

Hierdurch wird während, vor und nach jedem Steckvorgang gewährleistet, dass kein Schmutz in den Kontaktaufnahmeraum bzw. an die Kontaktflächen gelangen kann und eine Funktionsfähigkeit des Steckverbinders gewährleistet ist.This ensures during, before and after each mating process that no dirt can get into the contact receiving space or to the contact surfaces and a functionality of the connector is guaranteed.

Das zuvor beschriebene Ausführungsbeispiel ist nur exemplarisch, nicht abschließend zu verstehen. Somit können auch andere Steckverbinderformen und andere Kontaktanordnungen entsprechend der Idee der vorliegenden Erfindung ausgebildet sein.The embodiment described above is only an example, not to be understood. Thus, other connector shapes and other contact arrangements may be formed in accordance with the idea of the present invention.
