Vorzugsweise verdeckt das Deckelelement in der Ruheposition die gesamte Zugangsseite und nicht etwa nur einzelne zu Kontaktelementen führende Bohrungen. Ferner sind typischerweise zwei oder mehr Deckelelemente vorgesehen, wobei sich hier und im Folgenden eine Bezugnahme auf "das Deckelelement" immer auf alle Deckelelemente einer solchen größeren Anzahl erstrecken sollen. Des Weiteren betrifft die Erfindung eine Verschlusseinrichtung gemäß Merkmal b) der elektrischen Steckvorrichtung der vorstehend beschriebenen Art, da diese eine eigenständige Komponente für eine solche Steckvorrichtung darstellt. Alle auf eine elektrische Steckvorrichtung gerichteten Ansprüche und/oder Aussagen gelten daher analog auch für deren Verschlusseinrichtung. In the rest position, the cover element preferably covers the entire access side and not just individual bores leading to contact elements. Furthermore, typically two or more cover elements are provided, wherein here and in the following a reference to "the cover element" should always extend to all cover elements of such a larger number. Furthermore, the invention relates to a closure device according to feature b) of the electrical plug-in device of the type described above, since this represents an independent component for such a plug-in device. All claims and / or statements directed to an electrical plug-in device therefore also apply analogously to their closure device.
Die Erfindung betrifft ferner ein Verfahren zum Schutz der Zugangsseite des Kontaktbausteines einer elektrischen Steckvorrichtung, insbesondere einer Steckvorrichtung der oben beschriebenen Art. Gemäß dem Verfahren wird mindestens ein Deckelelement vor der Zugangsseite vorgesehen, das in einer Ruheposition die Zugangsseite bedeckt und das beim Einführen eines The invention further relates to a method for protecting the access side of the contact module of an electrical plug device, in particular a plug-in device of the type described above.

Die erfindungsgemäße elektrische Steckvorrichtung und das beschriebene The electrical plug-in device according to the invention and described
Verfahren haben den Vorteil, dass ein Kontaktbaustein bei Nichtbenutzung durch ein Deckelelement geschützt wird, wobei dieses Deckelelement jedoch Methods have the advantage that a contact module is protected when not in use by a cover element, but this cover element

Steckvorrichtungselementes in eine Öffnungsposition bewegt wird, in der es den Steckvorgang ermöglicht. Außer dem normalen Einführen des komplementären Steckvorrichtungselementes ist somit keine besondere zusätzliche Aktivität des Benutzers erforderlich, beispielsweise kein Öffnen eines Klappdeckels. Dies erhöht den Bedienungskomfort und erlaubt zum Beispiel ein einhändiges Plug device element is moved to an open position in which it allows the mating process. Thus, apart from the normal insertion of the complementary plug-in device element, no special additional activity of the user is required, for example no opening of a hinged lid. This increases the ease of use and allows, for example, a one-handed

Die "automatische" Bewegung des Deckelelementes von der Ruheposition in die Öffnungsposition wird beim Einführen des komplementären Steckvorrichtungselementes veranlasst. Dabei kann Hilfsenergie eingesetzt werden, beispielsweise durch Aktivierung eines elektrischen Antriebes. Vorzugsweise wird jedoch die notwendige Energie zur Bewegung des Deckelelementes vom eingeführten komplementären Steckvorrichtungselement aufgebracht, d. h. letztendlich vom Benutzer. The "automatic" movement of the lid member from the rest position to the open position is caused upon insertion of the complementary male member. In this case, auxiliary energy can be used, for example by activation of an electric drive. Preferably, however, the energy required to move the lid member is introduced from complementary plug device element applied, ie ultimately by the user.
Im Folgenden werden verschiedene Weiterbildungen der Erfindung beschrieben, die gleichermaßen für die elektrische Steckvorrichtung, für deren In the following, various developments of the invention will be described, which are equally for the electrical connector, for the
Verschlusseinrichtung, sowie für das Verfahren gelten und angewendet werden können. Closure device, and apply to the process and can be applied.
Gemäß einer ersten bevorzugten Ausführungsform wird das Deckelelement durch die entlang der Steckachse gerichtete Bewegung eines in den Kontaktbaustein eingeführten komplementären Steckvorrichtungselementes von der Ruheposition in die Öffnungsposition bewegt. Bei dieser Variante liefert somit die Bewegung des komplementären Steckvorrichtungselementes die Energie für die Bewegung des Deckelelementes. Ferner erfolgt das Öffnen der Verschlusseinrichtung According to a first preferred embodiment, the cover element is moved from the rest position into the open position by the movement of a complementary plug-in device element, which is directed along the plug-in axis, into the complementary plug-in device element. In this variant, thus, the movement of the complementary plug-in device element provides the energy for the movement of the cover element. Furthermore, the opening of the closure device takes place
vorteilhafterweise allein durch die "normale" Bewegung des Steckvorrichtungselementes in Richtung der Steckachse, d. h. ohne Zusatzbewegungen wie beispielsweise ein Schwenken oder Drehen des Steckvorrichtungselementes vor oder beim Einführen. advantageously solely by the "normal" movement of the plug-in device element in the direction of the plug-in axis, d. H. without additional movements such as pivoting or rotating the plug-in device element before or during insertion.
Das Deckelelement kann auf verschiedene Weise ausgestaltet und beweglich gelagert werden. Beispielsweise kann es schwenkbeweglich um eine oder mehrere Schwenkachsen gelagert sein, wobei die Schwenkachse insbesondere parallel oder senkrecht oder in jeder anderen Neigung zur Steckachse liegen kann. Wenn mehrere Deckelelemente vorhanden sind, kann jedes an einer eigenen individuellen Schwenkachse gelagert sein, oder es können zwei oder mehrere der Deckelelemente an einer gemeinsamen Schwenkachse gelagert sein. The lid member can be configured in various ways and movably mounted. For example, it may be pivotally mounted about one or more pivot axes, wherein the pivot axis may in particular be parallel or perpendicular or in any other inclination to the thru-axle. If a plurality of cover elements are present, each may be mounted on its own individual pivot axis, or it may be mounted on a common pivot axis two or more of the cover elements.
Alternativ kann das Deckelelement linear beweglich in einer Führung gelagert sein. Eine Linearbewegung des Deckelelementes kann vorzugsweise senkrecht zur Steckachse erfolgen, um das Deckelelement möglichst schnell aus der Zugangsseite herauszuführen. Gemäß einer besonders bevorzugten Ausführungsform weist das Deckelelement eine schräg zur Steckachse liegende Gleitfläche auf, mit der ein komplementäres Steckvorrichtungselement bei der Einführung in den Kontaktbaustein in Berührung kommt. Durch die Schräge der Gleitfläche wird beim Steckvorgang eine radial von der Steckachse nach außen gerichtete Kraftkomponente auf das Deckelelement ausgeübt, durch welche es aus der Ruheposition heraus in die Öffnungsposition gedrängt wird. Die Gleitfläche kann optional auch sehr schmal, d. h. annähernd linienförmig sein. Alternatively, the lid member may be mounted linearly movable in a guide. A linear movement of the cover element can preferably take place perpendicularly to the plug-in axis in order to bring the cover element out of the access side as quickly as possible. According to a particularly preferred embodiment, the cover element has a sliding surface lying obliquely to the plug-in axis, with which a complementary plug-in device element comes into contact with the introduction into the contact module. Due to the bevel of the sliding surface, a force component directed radially outwards from the plug-in axis is exerted on the cover element during the insertion process, by means of which it is forced out of the rest position into the open position. The sliding surface can optionally also be very narrow, ie approximately linear.
Das Deckelelement ist vorzugsweise in die Ruheposition vorgespannt, so dass es diese von selbst annimmt, wenn keine äußeren Kräfte einwirken. Die The lid member is preferably biased to the rest position so that it automatically assumes it when no external forces act. The
Vorspannung kann beispielsweise durch ein auf das Deckelelement wirkendes Federelement erzeugt werden. Preload can be generated for example by acting on the cover element spring element.
Während es grundsätzlich möglich ist, die Verschlusseinrichtung mit einem einzigen Deckelelement zu realisieren, werden vorzugsweise zwei oder mehr Deckelelemente verwendet. Der von jedem einzelnen Deckelelement von der Ruheposition bis zur Öffnungsposition zurückzulegende Weg wird auf diese Weise verkleinert. Besonders bevorzugt ist es, wenn die mehreren Deckelelemente symmetrisch bezüglich der Steckachse angeordnet sind. In diesem Falle kann erreicht werden, dass während eines Steckvorganges keine Kräfte resultieren, die ein komplementäres Steckvorrichtungselement von der Steckachse abdrängen. While it is basically possible to realize the closure device with a single cover element, preferably two or more cover elements are used. The distance traveled by each individual lid member from the rest position to the open position is reduced in this way. It is particularly preferred if the plurality of cover elements are arranged symmetrically with respect to the plug-in axis. In this case, it can be achieved that during a plug-in operation, no forces result that displace a complementary plug-in device element from the plug-in axis.
Wenn die Verschlusseinrichtung mindestens zwei bewegliche Deckelelemente aufweist, greifen diese in der Ruheposition vorteilhafterweise in ihrem If the closure device has at least two movable cover elements, these grip in the rest position advantageously in their

beispielsweise durch eine Nut und Feder Konstruktion realisiert werden. Der formschlüssige Eingriff erhöht die Stabilität in der Ruheposition und die Dichtheit gegenüber dem Eindringen von Fremdkörpern und/oder Feuchtigkeit. be realized for example by a tongue and groove construction. The positive engagement increases the stability in the rest position and the tightness against the ingress of foreign bodies and / or moisture.
Bei einer anderen bevorzugten Ausführungsform der Erfindung ist das In another preferred embodiment of the invention that is
Deckelelement geschützt hinter einer Blende angeordnet, d. h. zwischen der Blende und dem Kontaktbaustein. Die Blende kann insbesondere Teil eines Gehäuses sein, in welches der Kontaktbaustein eingebaut ist. Vorzugsweise gibt die Blende nicht mehr als die Querschnittsfläche frei, die zur Einführung eines komplementären Steckvorrichtungselementes in den Kontaktbaustein notwendig ist. In diesem Falle verschwindet das Deckelelement in seiner Öffnungsposition vollständig hinter der Blende. Das Deckelelement und sein Lagerungsmechanismus sind dann optimal vor Störungen geschützt. Lid element protected behind a panel arranged, ie between the panel and the contact block. The panel may in particular be part of a housing in which the contact module is installed. Preferably there the aperture no more than the cross-sectional area free, which is necessary for the introduction of a complementary plug-in device element in the contact module. In this case, the cover element disappears in its open position completely behind the panel. The cover element and its storage mechanism are then optimally protected against interference.
Gemäß einer weiteren Ausführungsform der Erfindung kann das According to a further embodiment of the invention, the
Steckvorrichtungselement einen Antrieb enthalten zur aktiven Bewegung des Deckelelementes von der Ruheposition in die Öffnungsposition oder umgekehrt. Insbesondere kann ein elektrisch betriebener Aktuator (Motor) für diesen Zweck vorgesehen sein, der über einen geeigneten Schaltmechanismus beim Einführen bzw. Annähern eines komplementären Steckvorrichtungselementes ausgelöst wird. Plug device element comprise a drive for active movement of the cover element from the rest position to the open position or vice versa. In particular, an electrically operated actuator (motor) may be provided for this purpose, which is triggered by a suitable switching mechanism during insertion or approach of a complementary plug-in device element.
Des Weiteren kann das Deckelelement optional in der Ruheposition arretierbar sein. Erst nach Lösen dieser Arretierung wird es dann möglich, das Deckelelement in die Öffnungsposition zu überführen und damit einen Steckvorgang freizugeben. Die Arretierung stellt somit eine zusätzliche Sicherung der Steckvorrichtung gegen unbefugte und/oder unsachgemäße Benutzung dar. Der Arretiermechanismus kann beispielsweise durch einen vom Benutzer anzuwendenden Schlüssel kontrolliert werden. Insbesondere kann er auch durch eine elektronische Furthermore, the cover element can optionally be locked in the rest position. Only after releasing this locking it is then possible to transfer the cover element in the open position and thus release a plug-in operation. The locking thus represents an additional safeguard of the plug-in device against unauthorized and / or improper use. The locking mechanism can be controlled, for example, by a key to be used by the user. In particular, he can also by an electronic
Steuerung kontrolliert werden, mit welcher beispielsweise die Autorisierung eines Nutzers überprüft wird. Controlled, for example, with which the authorization of a user is checked.

Geeignete Ausführungsformen von Kontaktbausteinen sind von herkömmlichen Steckvorrichtungen her bekannt. Der Übersichtlichkeit halber ist der Kontaktbaustein in allen anderen Figuren weggelassen. A contact module 1, which is indicated schematically in Figure 4. The contact module 1 can be configured, for example, as a socket part with electrical contact sockets. Suitable embodiments of contact components are known from conventional plug devices ago. For clarity, the contact module is omitted in all other figures.
Eine optionale Blende 2. Hierbei kann es sich beispielsweise um die An optional aperture 2. This may be, for example, the
Frontseite eines nicht weiter dargestellten Gehäuses handeln, in das die Steckvorrichtung eingebaut ist.  Front of a housing not shown act, in which the plug-in device is installed.
Eine Verschlusseinrichtung 10, welche zwischen der Blende 2 und dem Kontaktbaustein 1 angeordnet ist. In das Steckvorrichtungselement 100 kann von der Vorderseite her entlang einer Steckachse X ein komplementäres Steckvorrichtungselement (angedeutet als "SE" in Figur 4) durch eine "Zugangsseite" ZS in den Kontaktbaustein 1 eingeführt werden, wobei die Verschlusseinrichtung 10 die Zugangsseite ZS wahlweise verschließt oder freigibt. Die genannte Zugangsseite wird in Figur 4 durch den mit "ZS" bezeichneten Kragen an der Rückseite der Verschlusseinrichtung 10 umschlossen. Nachfolgend wird die Verschlusseinrichtung 10 insbesondere unter Bezugnahme auf die Figuren 5 und 6 näher erläutert. A closure device 10, which is arranged between the panel 2 and the contact module 1. In the plug-in device element 100, a complementary plug device element (indicated as "SE" in Figure 4) can be inserted through a "access side" ZS in the contact module 1 from the front along a plug axis X, wherein the closure device 10, the access side ZS either closes or releases , The mentioned access side is enclosed in FIG. 4 by the collar designated "ZS" on the rear side of the closure device 10. In the following, the closure device 10 will be explained in more detail with reference to FIGS. 5 and 6 in particular.
Die Verschlusseinrichtung 10 enthält zwei Deckelelemente 1 1 a, 1 1 b, die sich in der Ruheposition (Figuren 1 , 3, 5) vor die Zugangsseite ZS des Kontaktbausteins 1 legen und diese somit schützend verschließen. Vorzugsweise wird hierdurch ein Schutz nach Norm IP44 erreicht. The closure device 10 includes two cover elements 1 1 a, 1 1 b, which lie in the rest position (Figures 1, 3, 5) in front of the access side ZS of the contact module 1 and thus protectively close this. Preferably, this provides protection to IP44 standard.
Die beiden Deckelelemente 1 1 a, 1 1 b sind in einem gemeinsamen Gelenkpunkt 23 hinter der Blende 2 gelagert. Durch den Gelenkpunkt 23 wird eine Schwenkbewegung der Deckelelemente 1 1 a, 1 1 b um eine Schwenkachse A möglich, die parallel zur Steckachse X verläuft. The two cover elements 1 1 a, 1 1 b are mounted in a common hinge point 23 behind the panel 2. By the hinge point 23 is a pivotal movement of the cover elements 1 1 a, 1 1 b possible about a pivot axis A, which is parallel to the insertion axis X.
Im Gelenkpunkt 23 ist vorzugsweise ein Federelement wie beispielsweise eine Schenkelfeder (nicht dargestellt) vorgesehen, welches die Deckelelemente 1 1 a, 1 1 b in die Ruheposition vorspannt. Ein Auseinanderbewegen der Deckelelemente in die Öffnungsposition muss daher entgegen einer Rückstellkraft erfolgen. In the hinge point 23 is preferably a spring element such as a leg spring (not shown) is provided, which biases the cover elements 1 1 a, 1 1 b in the rest position. A movement apart of the cover elements in the open position must therefore be carried out against a restoring force.
Wie in Figur 5 erkennbar ist, sind die beiden Deckelelemente 1 1 a, 1 1 b As can be seen in Figure 5, the two cover elements 1 1 a, 1 1 b
vorzugsweise mit schrägen Gleitflächen 21 a, 21 b versehen, die trichterförmig in Richtung des Kontaktbausteines weisen und zur Steckachse einen Winkel α bilden von typischerweise zwischen 20° und 80°, besonders bevorzugt zwischen 40° und 50°. Ein in die Steckvorrichtung eingeführtes komplementäres preferably provided with inclined sliding surfaces 21 a, 21 b, which point in a funnel shape in the direction of the contact block and the plug axis form an angle α of typically between 20 ° and 80 °, more preferably between 40 ° and 50 °. An inserted into the plug-in complementary
Steckvorrichtungselement SE, beispielsweise ein Stecker, gleitet dann bei einer Bewegung entlang der Steckachse X auf den schrägen Flächen 21 a und 21 b, wodurch die Deckelelemente 1 1 a, 1 1 b von der Steckachse X weg radial nach außen gedrückt und in eine Öffnungsposition überführt werden. Vorteilhafterweise erfolgt dies "automatisch" beim normalen Einstecken des Steckvorrichtungs- elementes SE, d. h. bei einer Bewegung entlang der geraden Steckachse X. Plug device element SE, for example, a plug, then slides during a movement along the through-axle X on the inclined surfaces 21 a and 21 b, whereby the cover elements 1 1 a, 1 1 b pushed away from the plug-in axis X radially outward and transferred to an open position become. advantageously, this is done "automatically" during the normal insertion of the plug-in device element SE, ie during a movement along the straight plug-in axis X.
Wie in Figur 6 angedeutet ist, weisen die Deckelelemente 1 1 a und 1 1 b in ihrem Berührungsbereich eine Nut 22b bzw. einen Steg 22a auf, die nach dem Nut und Feder Prinzip in der Ruheposition formschlüssig ineinandergreifen. Auf diese Weise wird die Dichtheit und Stabilität der Anordnung erhöht. As indicated in FIG. 6, the cover elements 11a and 11b have, in their area of contact, a groove 22b or a web 22a, which intermesh positively in the rest position according to the tongue and groove principle. In this way, the tightness and stability of the arrangement is increased.
Die Deckelelemente 1 1 a, 1 1 b könnten selbstverständlich auch anders als dargestellt ausgestaltet sein. So könnten beispielsweise statt der Gleitflächen 21 a, 21 b lediglich linienförmige Kontaktrippen vorgesehen sein. Weiterhin könnte eine andere Anzahl an Deckelelementen vorliegen, oder die Deckelelemente könnten um andere Achsen schwenkbeweglich sein oder linear beweglich sein. The cover elements 1 1 a, 1 1 b could of course also be designed differently than shown. For example, instead of the sliding surfaces 21a, 21b, only linear contact ribs could be provided. Furthermore, there could be a different number of cover elements, or the cover elements could be pivotable about other axes or linearly movable.
Wie aus Figur 1 erkennbar ist, liegt die Verschlusseinrichtung 10 mit den As can be seen from Figure 1, the closure device 10 is located with the
Deckelelementen 1 1 a, 1 1 b hinter der Blende 2, so dass der gesamte Cover elements 1 1 a, 1 1 b behind the panel 2, so that the entire
Mechanismus dieser Einrichtung optisch und mechanisch durch die Blende 2 geschützt wird. Mechanism of this device is visually and mechanically protected by the aperture 2.
