Description

Die Erfindung betrifft eine elektrische Sicherheitssteckverbindung gemäß dem Oberbegriff des Patentanspruches 1 und geht von der FR-A-2 157 379 aus.The invention relates to an electrical safety connector according to the preamble of claim 1 and is based on FR-A-2 157 379.

Auch die sogenannten Sicherheitssteckdosen (Schuke-Dosen) geben keine Gewähr dafür, daß nicht von unbefugter oder unerfahrener Hand in den Stecker unmittelbar oder mit metallischen Teilen gegriffen und dadurch eine leitende Verbindung zwischen Netz und der betreffenden Person hergestellt wird, was nicht nur zu erheblichen gesundheitlichen Schäden, sondern sogar zu Lebensgefähr führen kann.Even the so-called safety sockets (Schuke sockets) do not guarantee that unauthorized or inexperienced hands will not grip the plug directly or with metallic parts, thereby establishing a conductive connection between the network and the person concerned, which is not only a significant health hazard Damage, but can even lead to life-threatening.

Eine elektrische Sicherheitssteckverbindung der eingangs genannten Art (FR-A-2 157 379) weist zwei voneinander durch eine isolierende Trennwand getrennte Kammern auf. Durch einen Magnetbestandteil am Stecker und einen Magnetkörper innerhalb der Steckdose wird die elektrische Verbindung geschlossen, sobald der Stecker in die Steckdose eingesteckt wird. Beim Herausziehen des Steckers wird der magnetische Kontakt aufgehoben, so daß auch die Kontakte innerhalb der Steckdose von den Netzzuleitungen getrennt sind. Die Kammern mit dieser bekannten elektrischen Sicherheitssteckverbindung sind in Einsteckrichtung des Steckers hintereinander angeordnet, wobei der in der Steckdose beweglich gelagerte Magnetkörper sich in der vorderen Kammer, also in der Steckeraufnahmekammer befindet. Dieser Magnetkörper ist über eine mechanische Verbindung mit einem elastischen Bauteil gekoppelt, welches mit den Netzzuleitungen verbundene Kontaktierungselemente aufweist. Wird der Stecker in die vordere Steckeraufnahmekammer eingesteckt, so wird der Magnetkörper angezogen und dadurch das elastische Bauteil so gegen die Kontaktbrücken gedrückt, daß die Kontaktelemente in Anlage gelangen und damit der Stecker an die Netzzuleitungen elektrisch leitend angeschlossen ist. Der Magnetkörper, der in der Steckeraufnahmekammer angeordnet ist, ist über ein mechanisches und damit verschleißanfälliges Kupplungsglied mit einem weiteren, elastisch ausgebildeten Bauteil gekoppelt, so daß indirekt über den angezogenen Magnetkörper der elektrisch leitende Anschluß zwischen Stecker und Netz herbeigeführt wird.An electrical safety plug connection of the type mentioned at the beginning (FR-A-2 157 379) has two chambers separated from one another by an insulating partition. A magnetic component on the plug and a magnetic body inside the socket close the electrical connection as soon as the plug is inserted into the socket. When the plug is pulled out, the magnetic contact is released, so that the contacts within the socket are also disconnected from the mains leads. The chambers with this known electrical safety plug connection are arranged one behind the other in the direction of insertion of the plug, the magnet body movably mounted in the socket being located in the front chamber, that is to say in the plug receiving chamber. This magnetic body is coupled via a mechanical connection to an elastic component which has contacting elements connected to the supply leads. If the plug is inserted into the front plug receiving chamber, the magnet body is attracted and the elastic component is pressed against the contact bridges in such a way that the contact elements come into contact and the plug is thus connected to the power supply lines in an electrically conductive manner. The magnetic body, which is arranged in the plug receiving chamber, is coupled to a further, elastically designed component via a mechanical and therefore wear-prone coupling member, so that the electrically conductive connection between the plug and the mains is brought about indirectly via the attracted magnetic body.

Schließlich sind Hilfsmagnetkörper für die Rückführung von Magnetkörpern in Sicherheitssteckverbindungen allgemein bekannt (BE-A-694 071, DE-A-2 643 031), durch welche sichergestellt ist, daß nach dem Herausziehen des Steckers die Magnetkörper wieder in ihre Ausgangslage zurück gestellt werden.Finally, auxiliary magnetic bodies for the return of magnetic bodies in safety plug connections are generally known (BE-A-694 071, DE-A-2 643 031), by which it is ensured that the magnetic bodies are returned to their starting position after the plug has been pulled out.

Aufgabe der Erfindung ist es, eine elektrische Sicherheitssteckverbindung zu schaffen, die gewährleistet, daß nach dem Herausziehen des Steckers jedes von außen zugängliche Teile der Steckdose stromlos, das heißt vom Netz getrennt ist.The object of the invention is to provide an electrical safety plug connection which ensures that, after the plug has been pulled out, each part of the socket which is accessible from the outside is de-energized, that is to say disconnected from the mains.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die geschlossene Kammer in Steckrichtung des Steckers in der Steckdose senkrecht unterhalb der Aufnahmekammer angeordnet ist und den beweglichen Magnetkörper aufnimmt, der normalerweise auf dem Kammerboden ruht, nach oben frei beweglich aufgenommen ist, in Richtung der Netzanschlüsse und in Richtung der Kontaktbrücken weisende elektrische Verbindungselemente aufweist und nur in seiner oberen angezogenen Stellung die in der Trennwand angeordneten Kontakbrücken mit den Netzzuleitungen verbindet, und daß unterhalb der geschlossenen Kammer ein Hilfsmagnetkörper zur Rückführung des Magnetkörpers auf den Kammerboden nach Abziehen des Steckers angeordnet ist.This object is achieved in that the closed chamber is arranged in the plug direction of the plug in the socket vertically below the receiving chamber and receives the movable magnetic body, which normally rests on the chamber floor, is freely movable upwards, in the direction of the power connections and in Direction of the contact bridges pointing electrical connecting elements and only in its upper tightened position connects the contact bridges arranged in the partition to the power supply lines, and that an auxiliary magnetic body for returning the magnetic body to the chamber bottom after removing the plug is arranged below the closed chamber.

Da das die Verbindungselemente tragende Bauteil in der in sich abgeschlossenen Kammer bei ausgestecktem Stecker keinerlei Verbindung zur oberen Aufnahmekammer aufweist, ist es völlig ungefährlich, in diese obere Kammer einzugreifen, da zu ihr keinerlei Zuleitung aus dem Netz führt. Es ist somit eine absolute Sicherheit der Steckdose und damit der gesamten Steckerverbindung gewährleistet. Der Stromfluß von der Steckdose zum Verbraucher wird nach dem Einstecken des Steckers in die obere Kammer automatisch hergestellt, ohne daß irgendjemand die Möglichkeit hat, an die Kontaktstellen zu kommen, da diese so untergebracht werden können, daß erst nach völligem Einschub das Steckers in die Steckdose das Anziehen des Magnetkörpers in der darunterliegenden in sich geschlossenen Kammer erfolgt.Since the component carrying the connecting elements in the self-contained chamber has no connection to the upper receiving chamber when the plug is unplugged, it is completely harmless to intervene in this upper chamber, since no supply line leads to it from the network. This ensures absolute safety of the socket and thus of the entire plug connection. The current flow from the socket to the consumer is automatically established after inserting the plug into the upper chamber without anyone being able to get to the contact points, since these can be accommodated so that the plug is only fully inserted into the socket the magnetic body is tightened in the self-contained chamber below.

Der Magnetkörper in der geschlossenen Kammer kann selbstverständlich aus mehreren getrennt geführten, jeweils eines der Verbindungselemente enthaltenden Einzelkörpern bestehen. Der Stecker braucht nicht ein voll magnetischer Stecker zu sein, auf dem über entsprechende Isolierungen entsprechende Kontaktstreifen oder -Plättchen angeordnet sind, die nach dem Einstecken des Steckers mit den Kontaktbrücken in Berührung kommen. Es kann sich auch um einen Stecker mit Steckerstiften handeln, die auf einem entsprechenden Magnetkörper, gegebenenfalls diesen isoliert durchsetzend, angeordnet sind, Man kann aber die Steckerstifte selbst auch als Magnete ausbilden. Es ist dabei nicht von Bedeutung, daß der Magnetkörper in der geschlossenen Kammer tatsächlich ein Magnet ist. Es kann sich auch um ein Weicheisenteil handeln, das zwischen dem Magnetkörper des Steckers und den Hilfsmagnetkörpern angeordnet ist, wobei die Magnete in ihrer Magnetkraft selbstverständlich so bemessen sein müssen, daß bei eingestecktem Stecker dieser Teil in Richtung des Steckers angezogen wird.The magnetic body in the closed chamber can, of course, consist of several separate bodies, each containing one of the connecting elements. The plug does not need to be a fully magnetic plug on which corresponding contact strips or plates are arranged over corresponding insulations and come into contact with the contact bridges after the plug has been inserted. It can also be a plug with plug pins, which are arranged on a corresponding magnetic body, possibly penetrating it in an insulated manner. However, the plug pins themselves can also be designed as magnets. It is not important that the magnetic body in the closed chamber is actually a magnet. It can also be a soft iron part which is arranged between the magnetic body of the plug and the auxiliary magnetic bodies, the magnets of course having to be dimensioned in their magnetic force such that this part is attracted in the direction of the plug when the plug is inserted.

In einem Sockel 1 befindet sich eine durch die Begrenzungslinie 2 gekennzeichnete Ausnehmung oder ein entsprechender Aufsatz. Dort ist eine Kammer 3 ausgebildet, die in sich geschlossen ist und nach Fertigmontage der Steckdose nach äußen hin abgeschlossen wird. In diese Kammer münden die Anschlüsse +, - und Masse M ein. Oberhalb dieser Kammer 3 befindet sich eine Aufnahmekammer 4, die von der Kammer 3 durch eine Trennwand 5 getrennt ist, in der Kontaktbrücken 6, 7 und 8 angeordnet sind. Bei dem wiedergegebenen Ausführungsbeispiel wird davon ausgegangen, daß die Stromzufuhr über eine +-Leitung, eine --Leitung unter Sicherung durch eine Erd- oder Masseleitung erfolgt. Selbstverständlich ist das Erfindungsprinzip darauf nicht beschränkt und es ist jede Art und Vielzahl von entsprechenden Zuleitungen, auch in Wechsel- oder Drehstromausführung grundsätzlich denkbar.In a base 1 there is a recess identified by the boundary line 2 or a corresponding attachment. A chamber 3 is formed there, which is self-contained and is closed to the outside after the socket has been fully assembled. Connections +, - and ground M open into this chamber. Above this chamber 3 there is a receiving chamber 4 which is separated from the chamber 3 by a partition 5 in which contact bridges 6, 7 and 8 are arranged. In the exemplary embodiment shown, it is assumed that the current is supplied via a + line, a - line while being secured by an earth or ground line. Of course, the principle of the invention is not limited to this, and any type and number of corresponding supply lines, in principle also in AC or three-phase design, are basically conceivable.

Unterhalb der Kammer 3 ist ein Magnet 9 vorgesehen.A magnet 9 is provided below the chamber 3.

Wie Fig. 2 erkennen läßt, ist in der nach Fertigmontage völlig geschlossenen kammer 3 ein Magnetkörper 10 vorgesehen, in dem isoliert Kontaktelemente 11, 12 und 13 vorgesehen sind. Man erkennt aus Fig. 2 auch wenigstens teilweise die Anschlüsse +, - und M.As can be seen in FIG. 2, a magnetic body 10 is provided in the chamber 3, which is completely closed after assembly, in which isolated contact elements 11, 12 and 13 are provided. 2 also shows at least partially the connections +, - and M.

Fig. 3 zeigt die gleiche Anordnung nach Einstekken des Steckers 13, der in Richtung des Pfeiles XIII aus seitlich herausgezeichneten, perspektivisch dargestellten Lage in die Kammer 3 eingesteckt wird. Der Stecker 13 weist Kontaktierungsstellen 14, 15 und 16 auf, die mit Drähten oder Litzen verbunden sind, welche in dem isolierten Kabel 17 zum nicht gezeichneten Verbraucher, z.B. eine Lampe, führen. Außerdem enthält der Stecker 13 einen magnetischen Bestandteil 18, der nach vollständigem Einstecken des Steckers 13 in die Kammer 4 (Fig. 1 und 2) dafür sorgt, daß der Magnetkörper 10 nach oben angezogen wird. Das führt dazu, daß die Anschlüsse +, - und M (vgl. Fig. 1 und 2) über die Kontaktbrücken 6, 7 und 8 mit den Kontaktierungsstellen 14,15 und 16 des Steckers in Verbindung kommen und damit über das en den Stecker 13 angeschlossene Kabel 17 dem Verbraucher Strom zugeführt wird. Wird der Stecker herausgezogen, dann ist der Magnetschluß zwischen dem Magneten 18 und dem Magnetkörper 10 unterbrochen und der Magnetkörper 10 fällt nach unten ab, wobei dieses Abfallen durch den Hilfsmagneten 9 unterstützt wird. Nach dem Herausziehen des Steckers 13 befindet sich also kein nach außen hin zugänginger Teil der Steckdose in elektrischer Verbindung mit dem Netz, wodurch eine absolute Sicherheit gewährleistet ist.Fig. 3 shows the same arrangement after inserting the plug 13, which is inserted in the direction of arrow XIII from the side drawn out, perspective position shown in the chamber 3. The plug 13 has contact points 14, 15 and 16 which are connected to wires or strands which are connected in the insulated cable 17 to the consumer, not shown, e.g. a lamp, lead. In addition, the plug 13 contains a magnetic component 18 which, after the plug 13 has been fully inserted into the chamber 4 (FIGS. 1 and 2), ensures that the magnetic body 10 is attracted upward. The result is that the connections +, - and M (see FIGS. 1 and 2) via the contact bridges 6, 7 and 8 come into contact with the contact points 14, 15 and 16 of the plug and thus via the plug 13 connected cable 17 is supplied to the consumer power. If the plug is pulled out, then the magnetic connection between the magnet 18 and the magnet body 10 is interrupted and the magnet body 10 falls downwards, this falling off being supported by the auxiliary magnet 9. After the plug 13 has been pulled out, there is therefore no part of the socket which is externally accessible and is in electrical connection with the mains, which ensures absolute security.

Bei der Ausführungsform nach Fig. 4 sind die einzelnen Kontaktelemente 41, 42, 43 voneinander getrennt, aber mit entsprechenden Magneten 44, 45, 46 versehen, so daß nach dem Einstecken des Steckers 47 in die Kammer 4 wiederum das Anziehen dieser einzelnen Kontaktelemente und damit der Stromschluß zum Verbraucher erfolgt. Hier ist der Hilfsmagnet 49 gegebenenfalls als mehrteiliger Magnet ausgeführt, wie die Zeichnung erkennen läßt.In the embodiment according to FIG. 4, the individual contact elements 41, 42, 43 are separated from one another, but are provided with corresponding magnets 44, 45, 46, so that once the plug 47 has been inserted into the chamber 4, these individual contact elements are tightened again and thus the electrical connection to the consumer occurs. Here, the auxiliary magnet 49 is optionally designed as a multi-part magnet, as can be seen in the drawing.

Der Stecker 47 weist bei dieser Ausführungsform die Gestalt nach Fig. 5 auf und ist mit drei Steckerstiften 51, 52, 53 versehen, die in die entsprechenden Öffnungen +, -, M eingesteckt werden, so daß nach dem Anheben der entsprechenden Einzelmagnets 44, 45, 46 den Kontakt zwischen dem Kabel 58 und damit dem Verbraucher und dem an +, -, M anliegenden Netz hergestellt ist.5 and is provided with three connector pins 51, 52, 53, which are inserted into the corresponding openings +, -, M, so that after lifting the corresponding individual magnet 44, 45 , 46 the contact between the cable 58 and thus the consumer and the network connected to +, -, M is established.

Eine weitere Ausführungsform ist in den Fig. 6 bis 8 wiedergegeben. Die Anordnung der einzelnen Kammern ist die gleiche wie bei den vorhergehenden Ausführungsformen. Hier ist lediglich dafür gesorgt, daß am Stecker 81 nach Fig. 8 ein Magnetteil 82 vorgesehen ist, der von den einzelnen Steckerstiften 83, 84, 85 entsprechend isoliert ist. Wird dieser Stecker mit seinem Magnetteil 81 in die obere Aufnahmekammer eingesteckt, so sorgt der Magnetteil 81 für das Anziehen des Magnetkörpers 86, der die entsprechenden Kontaktelemente trägt, die die Verbindung zu den Steckerstiften 83, 84, 85 über die Öffnungen 87, 88, 89 in die die Steckerstifte 83, 84, 85 greifen, her. Auch hier ist wieder ein Hilfsmagnet 90 vorgesehen. Die Verbindung zwischen den Öffnungen 87, 88, 89 bzw. deren metallischen Boden oder metallischer Auskleidung liegt hinter der Zeichenebene und ist somit nicht sichtbar.Another embodiment is shown in FIGS. 6 to 8. The arrangement of the individual chambers is the same as in the previous embodiments. Here it is only ensured that a magnetic part 82 is provided on the connector 81 according to FIG. 8, which is correspondingly insulated from the individual connector pins 83, 84, 85. If this plug is inserted with its magnetic part 81 into the upper receiving chamber, then the magnetic part 81 ensures that the magnetic body 86, which carries the corresponding contact elements, connects the plug pins 83, 84, 85 via the openings 87, 88, 89 into which the plug pins 83, 84, 85 engage. An auxiliary magnet 90 is again provided here. The connection between the openings 87, 88, 89 or their metallic base or metallic lining lies behind the plane of the drawing and is therefore not visible.
