Aus der deutschen Patentschrift
Mit der Erfindung soll ein Steckverbindersystemgeschaffen werden, bei dem der Stecker sicher in der Buchse gehaltenist und bei dem dennoch bei Überschreiteneiner bestimmten Zugkraft am Anschlusskabel der Stecker ohne Gefahrvon Beschädigungenvon der Buchse gelöstwerden kann.The invention aims to provide a connector systembe created in which the plug is held securely in the socketand with which it is nevertheless exceededa certain tensile force on the connection cable of the plug without dangerof damagedetached from the socketcan be.
Erfindungsgemäß ist hierzu ein Steckverbindersystemmit einer Buchse, einem in die Buchse einführbaren und mit einem Anschlusskabelverbindbaren Stecker und Haltemitteln zum lösbaren Halten des Steckersin der Buchse vorgesehen, bei dem die Haltemittel wenigstens einenim Stecker und/oder der Buchse angeordneten Magneten aufweisen.According to the invention, this is a connector systemwith a socket, an insertable into the socket and with a connection cableconnectable plugs and holding means for releasably holding the plugprovided in the socket, in which the holding means at least onehave magnets arranged in the plug and / or the socket.
Auf diese Weise kann die Sicherungdes Steckers in der Buchse durch Magnetkraft erfolgen. Infolgedessenkann auf Verriegelungselemente verzichtet werden und die zum Lösen desSteckers erforderliche Zugkraft ist unabhängig von Verschleiß oder Verschmutzungvon Verriegelungselementen. Wenn eine Zugkraft auf das Anschlusskabeldie Haltekraft des Magneten überschreitet,kann sich der Stecker von der Buchse lösen. Da die Haltekraft durchden Magneten vorgegeben ist, ist die Einhaltung der maximalen Zugkraftsichergestellt und der Stecker kann sich in der Buchse nicht verklemmen. Daserfindungsgemäße Steckverbindersystemkann fürelektrische Anschlüsse,informationstechnische Anschlüsseund beispielsweise auch fürLichtwellenleiter verwendet werden.This way the backupof the plug in the socket by magnetic force. Consequentlycan be dispensed with locking elements and for releasing thePlug's required tensile force is independent of wear or dirtof locking elements. If a pull on the connection cablethe holding force of the magnet exceedsthe plug can come loose from the socket. Because the holding force bythe magnets are given, the maximum pulling force must be observedensured and the plug cannot get stuck in the socket. TheConnector system according to the inventioncan forelectrical connections,IT connectionsand for example also forOptical fibers are used.
In Weiterbildung der Erfindung sindim Stecker und der Buchse Elemente zum Führen eines magnetischen Feldsvorgesehen, wobei in vollständigin die Buchse eingesteckten Zustand des Steckers zwischen Steckerund Buchse ein geschlossener magnetischer Kreis gebildet ist.In further development of the inventionin the plug and the socket elements for guiding a magnetic fieldprovided, being in completethe plug inserted into the socket between the plugand socket a closed magnetic circuit is formed.
Das Vorsehen von Elementen zum Führen einesmagnetischen Felds im Stecker und Buchse ermöglicht es, eine ausreichendeHaltekraft zu er zeugen bzw. kleinere Magneten vorsehen zu können. DieElemente sind vorzugsweise als Eisenbügel oder Eisenjoche ausgeführt.The provision of elements for leading onemagnetic field in the plug and socket allows sufficientHolding power to testify or to be able to provide smaller magnets. TheElements are preferably designed as iron brackets or iron yokes.
In Weiterbildung der Erfindung istim Stecker und/oder in der Buchse ein jochartiges Element zum Führen desmagnetischen Feldes vorgesehen.In development of the inventionin the plug and / or in the socket a yoke-like element for guiding themagnetic field provided.
Auf diese Weise kann ein geschlossenermagnetischer Kreis überStecker und Buchse realisiert werden, der aus dem Magneten, demjochartigen Element in Stecker oder Buchse, weiteren Elementen zumFührendes Magnetfelds sowie den gegebenenfalls vorhandenen Luftspaltenzwischen den aneinander gegenüberliegendenEnden der jochartigen oder bügelartigenElemente von Stecker und Buchse besteht.In this way, a closedmagnetic circle overPlug and socket can be realized from the magnet, theyoke-like element in plug or socket, further elements forTo leadof the magnetic field and any air gaps that may be presentbetween the opposing onesEnds of yoke-like or bow-likeThere are elements of plug and socket.
In Weiterbildung der Erfindung istder wenigstens eine Magnet als Permanentmagnet ausgebildet.In development of the inventionthe at least one magnet is designed as a permanent magnet.
Auf diese Weise kann die Haltekraftpermanent und ohne zusätzlicheEnergiezufuhr erzeugt werden.In this way, the holding forcepermanently and without additionalEnergy supply can be generated.
In Weiterbildung der Erfindung istder wenigstens eine Magnet als Elektromagnet ausgebildet.In development of the inventionthe at least one magnet is designed as an electromagnet.
Der Einsatz eines Elektromagneten,als einziger Magnet oder in Verbindung einem Permanentmagneten,erlaubt es, die Haltekraft einzustellen und gegebenenfalls auchwährenddes Betriebs zu verändern.Beispielsweise kann die Haltekraft dadurch verringert werden, dassein Elektromagnet entgegengesetzt zu einem Permanentmagnet im elektrischen Kreisgepolt wird. Es ist aber beispielsweise auch möglich, zum Abwerfen des Steckerslediglich einen Elektromagneten abzuschalten oder seine Haltekraft zuverringern.The use of an electromagnet,as the only magnet or in connection with a permanent magnet,allows the holding force to be adjusted and, if necessary, alsowhilechange the operation.For example, the holding force can be reduced in thatan electromagnet opposite to a permanent magnet in the electrical circuitis poled. However, it is also possible, for example, to eject the plugjust switch off an electromagnet or its holding forcereduce.
In Weiterbildung der Erfindung istim Stecker und/oder der Buchse wenigstens ein gegen die Haltekraftdes wenigstens einen Magneten wirkendes Auswerferfederelement vorgesehen.In development of the inventionat least one against the holding force in the plug and / or the socketof the at least one magnet acting ejector spring element is provided.
Auf diese Weise kann die Abwurfkraftzum Abwerfen des Steckers durch ein Federelement erzeugt werdenund um das Abwerfen auszulösen,ist lediglich eine Verringerung der Magnethaltekraft erforderlich.Das Vorsehen eines Auswerferfederelements erlaubt es, mit einfachenMitteln eine der magnetischen Haltekraft entgegengerichtete Auswurfkraftzu erzeugen und einen Abwurfvorgang durch einfaches Verringern dermagnetischen Haltekraft auszulösen.In this way, the ejection forcebe generated by a spring element for ejecting the plugand to trigger the dropping,only a reduction in the magnetic holding force is required.The provision of an ejector spring element allows simpleAverage an ejection force opposite to the magnetic holding forceto generate and throw off by simply reducing thetrigger magnetic holding force.
In Weiterbildung der Erfindung istzwischen Stecker und Buchse und ein geschlossener magnetischer Kreisgebildet und wenigstens ein Magnetfeldsensor zur Erfassung des Magnetfelsim magnetischen Kreis ist vorgesehen.In a development of the invention is between the plug and socket and a closed magneti shear circle and at least one magnetic field sensor for detecting the magnetic field in the magnetic circuit is provided.
Mittels des Magnetfeldsensors kannbeispielsweise festgestellt werden, ob ein Stecker ordnungsgemäß eingestecktist oder ob sich überhaupt einStecker in der Buchse befindet. Beispielsweise ist hierzu sowohlim Stecker als auch in der Buchse ein Permanentmagnet vorgesehen,so dass sich bei eingestecktem Stecker das Magnetfeld im magnetischenKreis deutlich verändert.By means of the magnetic field sensorFor example, it can be determined whether a plug is properly insertedis or whether there is anyPlug is in the socket. For example, this is botha permanent magnet is provided in both the plug and the socket,so that when the plug is inserted, the magnetic field in the magneticCircle changed significantly.
In Weiterbildung der Erfindung istzwischen Stecker und Buchse ein geschlossener magnetischer Kreisgebildet und im magnetischen Kreis ist ein Elektromagnet vorgesehen,der unter Steuerung eines Steuergeräts ansteuerbar ist.In development of the inventiona closed magnetic circuit between plug and socketformed and an electromagnet is provided in the magnetic circuit,which can be controlled under the control of a control unit.
Auf diese Weise kann mittels desSteuergerätsein Abwerfen des Steckers ausgelöstwerden, beispielsweise wenn bei einem Brand sämtliche elektrischen Geräten vonihrer Stromversorgung getrennt werden sollen. Eine Ansteuerung desElektromagneten kann im Sinne einer Umpolung oder auch im Sinneeiner Verringerung der Haltekraft erfolgen.In this way, by means ofECUthe plug was ejected, for example, if all electrical devices fromtheir power supply should be disconnected. A control of theElectromagnets can be used in the sense of polarity reversal or in the sensea reduction in the holding force.
In Weiterbildung der Erfindung istzwischen Stecker und Buchse ein geschlossener magnetischer Kreisgebildet und ein Magnetfeldsensor ist für den magnetischen Kreis vorgesehen,wobei ein Steuergerätin Abhängigkeitdes Ausgangssignals des Magnetfeldsensors ein Zustandsignal ausgibt.In development of the inventiona closed magnetic circuit between plug and socketformed and a magnetic field sensor is provided for the magnetic circuit,being a control unitdependent onoutputs a status signal of the output signal of the magnetic field sensor.
Auf diese Weise kann über dasZustandsignal des Steuergerätsfestgestellt werden, ob sich ein Stecker in einer bestimmten Buchsebefindet und beispielsweise auch, ob dieser Stecker ordnungsgemäß eingestecktist. Beispielsweise kann in einer Überwachungszentrale in einfacherWeise festgestellt werden, ob beispielsweise ein Patiententerminalin einem bestimmten Zimmer eingesteckt ist und dieses Zimmer dadurchfür eineBettenbelegung vorbereitet ist. In Abhängigkeit des Ausgangssignalsdes Magnetfeldsensors kann beispielsweise auch der Elektromagnetangesteuert werden.That way, about thatStatus signal of the control unitdetermine whether there is a plug in a particular socketand, for example, whether this connector is properly insertedis. For example, in a monitoring center it can be easierHow to determine whether, for example, a patient terminalis plugged into a certain room and this roomfor oneBedding is prepared. Depending on the output signalthe magnetic field sensor can, for example, also the electromagnetcan be controlled.
