Description

Die Erfindung betrifft eine elektrische Verbindungsvorrichtung nach der im Oberbegriff von Anspruch 1 näher definierten Art.The invention relates to an electrical connection device according to the closer defined in the preamble of claim 1.

Eine Verbindungsvorrichtung dieser Art ist in der WO 9508910 A1 beschrieben.A connecting device of this type is in the WO 9508910 A1 described.

Durch die elastische Anordnung der Kontaktelemente wenigstens einer Einrichtung lassen sich auch mehrere Kontakte optimal zueinander ausrichten und ein sehr guter Flächenkontakt herstellen. Auf diese Weise lassen sich auch höhere Amperezahlen übertragen bzw. weiterleiten.Due to the elastic arrangement of the contact elements of at least one device, it is also possible to optimally align a plurality of contacts with one another and to produce a very good surface contact. In this way, even higher ampere numbers can be transmitted or forwarded.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, die vorbekannte elektromechanische Verbindungsvorrichtung weiter zu verbessern, insbesondere für eine Serienfertigung und für eine Vielzahl von Kontaktverbindungen noch geeigneter zu machen.The present invention has for its object to further improve the previously known electromechanical connection device, in particular for mass production and for a variety of contact connections to make even more appropriate.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, dass eine Vielzahl von Kontaktelementen wenigstens einer der beiden Einrichtungen nebeneinander in einer rasterförmigen Ausgestaltung angeordnet sind, dass die in die rasterförmige Ausgestaltung eingesetzten Kontaktelemente elastisch gelagert sind, und dass die rasterförmige Ausgestaltung auf der von den Kontaktelementen abgewandten Seite an einer Pressbrücke anliegt.According to the invention this object is achieved in that a plurality of contact elements of at least one of the two devices are arranged side by side in a grid-shaped configuration, that the contact elements used in the grid-shaped configuration are elastically mounted, and that the grid-shaped configuration on the side facing away from the contact elements a pressing bridge is applied.

Durch die Anordnung der Kontaktelemente wenigstens einer Einrichtung in der rasterförmigen Ausgestaltung lassen sich auf engstem Raum eine Vielzahl von Kontaktverbindungen schaffen. Praktisch sind die Kontaktelemente wie Lettern einer Druckerpresse nebeneinander angeordnet, wobei die Länge praktisch beliebig gewählt werden kann. Durch die elastische Lagerung sind die einzelnen Kontaktelemente frei voneinander beweglich, wodurch sich optimale Kontaktverbindungen mit Flächenberührung ergeben. Die Pressbrücke sorgt ebenfalls für einen einwandfreien Flächenkontakt aufgrund der gemeinsamen Lagerung bzw. Abstützung der Kontaktelemente auf ihrer Rückseite. Die erforderliche Elastizität für die Kontaktelemente kann in einer sehr vorteilhaften Ausgestaltung der Erfindung dadurch erreicht werden, dass die Pressbrücke elastisch ausgebildet ist. Durch eine elastische Pressbrücke können neben einem sehr guten Flächenkontakt auch Toleranzungenauigkeiten ausgeglichen werden. Gleichzeitig wird dabei der Druck gleichmäßig auf die einzelnen Kontaktelemente verteilt.The arrangement of the contact elements of at least one device in the grid-shaped configuration can be created in a confined space a plurality of contact connections. Practically, the contact elements such as letters of a printing press are arranged side by side, wherein the length can be chosen practically arbitrary. Due to the elastic mounting the individual contact elements are freely movable from each other, resulting in optimal contact connections with surface contact. The pressing bridge also ensures a perfect surface contact due to the common storage or support of the contact elements on its back. The required elasticity for the contact elements can be achieved in a very advantageous embodiment of the invention in that the press bridge is formed elastically. Through an elastic pressing bridge tolerance inaccuracies can be compensated in addition to a very good surface contact. At the same time the pressure is evenly distributed to the individual contact elements.

Zusätzlich oder alternativ können die Kontaktelemente wenigstens teilweise in einer elastischen Umhüllung eingebettet sein.Additionally or alternatively, the contact elements may be at least partially embedded in an elastic sheath.

Im Bedarfsfalle lässt sich die Vorrichtung entsprechend dem rasterförmigen Gerippe beliebig verlängern, ähnlich wie Schriftdrucklettern.If necessary, the device according to the grid-shaped skeleton can be extended as desired, much like typographic letters.

In einer vorteilhaften Ausgestaltung der Erfindung kann vorgesehen sein, dass die Strom- oder Datengebereinrichtung und die Stromabnahme- oder Datenabnahmeeinrichtung jeweils mit Magnetkörpern versehen sind, wobei die Magnetkörper der Stromabnahme- oder Datenabnahmeeinrichtung gegenüberliegend zu den Magnetkörpern der Stromgeber- oder Datengebereinrichtung angeordnet sind.In an advantageous embodiment of the invention can be provided that the power or data generator device and the power take-off or data pickup each with Magnet bodies are provided, wherein the magnetic body of the power take-off or data pickup device are arranged opposite to the magnetic bodies of the current generator or data-generating device.

Mit der erfindungsgemäßen Vorrichtung lässt sich ein punktgenaues flächenförmiges Kontaktieren, auch blind, auf sehr kurzer Strecke und unter Duldung von größeren Toleranzen der elektrisch zu verbindenden Teile erreichen.With the device according to the invention can be a pinpoint surface contact, even blind, achieve a very short distance and tolerated by larger tolerances of the parts to be electrically connected.

In einer vorteilhaften konstruktiven Ausgestaltung kann vorgesehen sein, dass die rasterförmige Ausgestaltung durch ein Gerippe gebildet ist, wobei das Gerippe wenigstens annähernd eine mit rechtwinkligen Windungen verlaufende Mäanderform aufweisen kann.In an advantageous structural embodiment, it can be provided that the grid-shaped configuration is formed by a skeleton, wherein the skeleton can have at least approximately a meandering shape running with right-angled turns.

Durch die erfindungsgemäße Mäanderform lässt sich praktisch als Meterware ein rasterförmiges Gerippe bilden, welches entsprechend in beliebiger Länge abgelängt werden kann. In die einzelnen Mäander werden dann die Kontaktelemente eingeschoben und in vorteilhafter Weise im Spritzgussverfahren mit der elastischen Umhüllung versehen, wobei die einzelnen Mäander entsprechend mit dem Spritzguss aufgefüllt werden können. Man kann die nach hinten offenen Mäander jedoch auch freilassen, womit durch den damit vorliegenden Luftspalt eine Erhöhung der Elastizität erreicht wird. Wenn man die Mäanderbreite dabei geringfügig enger macht, als die Dicke der Kontaktelemente, dann werden diese durch Klemmwirkung sicher in den nach vorne ragenden Mäandern gehalten.As a result of the meandering mold according to the invention, a grid-shaped skeleton can be formed practically by the meter, which can be cut to length in any desired length. In the individual meanders, the contact elements are then inserted and provided in an advantageous manner by injection molding with the elastic sheath, wherein the individual meanders can be filled in accordance with the injection molding. However, it is also possible to leave open the meander which is open to the rear, thus increasing the elasticity due to the air gap therewith. If you make the meander width slightly narrower than the thickness of the contact elements, then they are held by clamping action safely in the forward projecting meanders.

Zur Flächenkontaktvergrößerung kann vorgesehen sein, dass zwei nebeneinander liegende Kontaktelemente durch ein leitendes Brückenteil miteinander verbunden sind.For surface contact enlargement can be provided that two adjacent contact elements are interconnected by a conductive bridge part.

Selbstverständlich werden in diesem Falle auch zwei Kontaktelemente der jeweils anderen Einrichtung ebenfalls mit einem leitenden Brückenteil miteinander verbunden. Auf diese Weise wird eine deutlich größere Kontaktfläche geschaffen, wodurch an dieser Stelle noch höhere Ströme übertragen werden können.Of course, in this case, two contact elements of the other device are also connected to each other with a conductive bridge part. In this way, a significantly larger contact area is created, whereby even higher currents can be transmitted at this point.

Anstelle einer Verbindung der Strom- oder Datengebereinrichtung mit der Stromabnahme-.oder Datenabnahmeeinrichtung über die Magnetkörper durch Erzeugung einer magnetischen Haftkraft können die beiden Einrichtungen selbstverständlich auch auf beliebig andere Weise miteinander verbunden werden, wie z.B. eine kraft- oder formschlüssige Verbindung mit oder ohne Verriegelungen.Of course, instead of connecting the power or data-generating device to the power take-off device via the magnetic bodies by generating a magnetic force, the two devices can be interconnected in any other way, e.g. a non-positive or positive connection with or without locks.

Vorteilhafte Weiterbildungen und Ausgestaltungen ergeben sich aus den übrigen Unteransprüchen und aus dem nachfolgend anhand der Zeichnung prinzipmäßig beschriebenen Ausführungsbeispiel.Advantageous developments and refinements emerge from the remaining dependent claims and from the exemplary embodiment described in principle below with reference to the drawing.

Die Figuren 1 und 2 zeigen jeweils eine Strom- oder Datengebereinrichtung 1 mit einem Gehäuse 2, in welchem eine Vielzahl von nebeneinander als Flächenkontakte ausgebildete Kontaktelemente 3 angeordnet sind. In dem Gebergehäuse 2 sind zwei oder im Bedarfsfalle auch mehrere Magnetkörper 4 in Form von Eisenkernen oder von Magneten auf Abstand voneinander angeordnet.The FIGS. 1 and 2 each show a power or data supply device 1 with a housing 2, in which a plurality of juxtaposed as surface contacts contact elements 3 are arranged. In the transmitter housing 2, two or, if necessary, a plurality of magnetic body 4 in the form of iron cores or magnets are arranged at a distance from each other.

Für eine elektrische Verbindung wird eine Stromabnahme- oder Datenabnahmeeinrichtung 5 mit einem Nehmergehäuse 6 derart der Strom- oder Datengebereinrichtung 1 gegenüberliegend angeordnet, dass Magnete oder Magnetkörper 7, die in dem Nehmergehäuse 6 angeordnet sind, den Magnetkörpern 4, die in dem Gebergehäuse 2 angeordnet sind, gegenüber liegen. Wenn die Magnetkörper 7 als Magnete ausgebildet sind, und die Magnetkörper 4 als Eisenkerne, ist es nicht erforderlich, auf eine Gegenpoligkeit zu achten. Falls die Magnetkörper 4 ebenfalls als Magnete ausgebildet sind, ist dafür zu sorgen, dass jeweils entgegengesetzt gerichtete Pole gegenüberliegend angeordnet werden.For an electrical connection, a current collection or data removal device 5 with a slave housing 6 is arranged opposite the current or data supply device 1 such that magnets or magnetic bodies 7 which are arranged in the slave housing 6, the magnetic bodies 4, which are arranged in the encoder housing 2 , lie opposite. When the magnetic bodies 7 are formed as magnets, and the magnetic bodies 4 as iron cores, it is not necessary to pay attention to a mutual pole. If the magnetic bodies 4 are also designed as magnets, it must be ensured that oppositely directed poles are arranged opposite one another.

Zur Verstärkung der Magnetkraft können die Magnete 7 zusätzlich noch mit einem Eisenmantel 8 ummantelt werden, damit sich eine Magnetkrafterhöhung ergibt. Derartige Ausgestaltungen von Magneten sind allgemein bekannt, weshalb hier nicht näher darauf eingegangen wird.To strengthen the magnetic force, the magnets 7 can be additionally sheathed with an iron sheath 8, thus resulting in a Magnetkrafterhöhung. Such embodiments of magnets are well known, which is why will not be discussed here in detail.

Zur Vereinfachung wird nachfolgend nur von einer Strömgebereinrichtung 1 und einer Stromabnahmeeinrichtung 5 gesprochen. Selbstverständlich sind die beiden Einrichtungen auch für eine Datenübertragung im Sinne einer Datengebereinrichtung und einer Datenabnahmeeinrichtung geeignet.For the sake of simplicity, only a flow device 1 and a power take-off device 5 will be discussed below. Of course, the two devices are also suitable for data transmission in the sense of a data-generating device and a data-picking device.

Mit Magnetkörper werden ganz allgemein Magnete, magnetisierbare Teile oder magnetische Teile bezeichnet, welche unter dem Einfluss eines Magneten magnetisch reagieren. Wesentlich ist lediglich, dass die Magnetkörper 4 der Stromgebereinheit 1 und der Stromabnahmeeinrichtung 5 derart zusammenwirken, dass sich eine Magnethaftkraft auf beide Teile durch ein magnetisches Feld ergibt.Magnetic bodies generally designate magnets, magnetizable parts or magnetic parts which react magnetically under the influence of a magnet. It is only essential that the magnetic body 4 of the current generator unit 1 and the current collecting device 5 cooperate in such a way that a magnetic force force results on both parts through a magnetic field.

Die Stromabnahmeeinrichtung 5 ist ebenfalls mit Kontaktelementen 9 in Form von Flächenkontakten versehen, welche in dem Nehmergehäuse 6 derart nebeneinander angeordnet sind, dass sie bei einer Verbindung der Stromgebereinrichtung 1 mit der Stromabnahmeeinrichtung 5 jeweils den Kontaktelementen 3 der Stromgebereinheit 1 gegenüberliegend angeordnet sind.The power take-off device 5 is likewise provided with contact elements 9 in the form of surface contacts, which are arranged in the slave housing 6 next to one another in such a way that, when the current-carrying device 1 is connected to the current-collecting device 5, they are respectively arranged opposite the contact elements 3 of the current transmitter unit 1.

Die Figuren 1 und 2 zeigen jeweils die Position kurz vor Kontaktierung der Stromgebereinrichtung 1 mit der Stromabnahmeeinrichtung 5 und damit kurz vor einer Kontaktverbindung zwischen den Kontaktelementen 3 und 9.The FIGS. 1 and 2 each show the position shortly before contacting the power supply device 1 with the current collection device 5 and thus shortly before a contact connection between the contact elements 3 and 9.

Die Kontaktelemente 3 der Stromgebereinrichtung 1 sind in einer rasterförmigen Ausgestaltung in Form eines rasterförmigen Gerippes 10 in dessen Aussparungen angeordnet. Das rasterförmige Gerippe 10 weist eine Mäanderform mit rechtwinkligen Windungen auf, wobei die Kontaktelemente 3 jeweils in einem Mäander bzw. einer Aussparung zwischen zwei Rippen 11 und 12 eingelegt, vorzugsweise eingeklemmt, werden. Aufgrund der Mäanderform ergibt sich jeweils zu dem nächsten Mäander mit dem nächsten Kontaktelement 3 entsprechend rückseitig ein Spalt 13, durch den eine Beweglichkeit der Kontaktelemente 3 gegeben ist. In die vorderen Mäander, die der Stromabnahmeeinrichtung 5 zugewandt sind, sind die Kontaktelemente 3 eingeklemmt.The contact elements 3 of the current-carrying device 1 are arranged in a grid-shaped configuration in the form of a grid-shaped skeleton 10 in its recesses. The grid-shaped frame 10 has a meandering shape with rectangular turns, wherein the contact elements 3 each inserted in a meander or a recess between two ribs 11 and 12, preferably clamped. Due to the meandering shape, a gap 13 results in each case corresponding to the rear side on the next meander with the next contact element 3, by means of which a mobility of the contact elements 3 is provided. In the front meander, which are facing the current collection device 5, the contact elements 3 are clamped.

Zusätzlich sind zur besseren Führung, jedoch unter Einhaltung einer Elastizität, die Kontaktelemente 3 jeweils im vorderen Bereich von einer elastischen Umhüllung 14 umgeben sein, welche sich bis kurz vor die Kontaktflächen 15 jedes Kontaktelementes 3 erstreckt.In addition, for better guidance, but in compliance with an elasticity, the contact elements 3 are each surrounded in the front region by an elastic sheath 14, which extends to just before the contact surfaces 15 of each contact element 3.

Die elastische Umhüllung 14 kann z.B. als Kunststoff im Spritzgussverfahren auf- bzw. eingebracht werden. Selbstverständlich kann die elastische Umhüllung auch auf andere Weise aufgebracht werden, wie z.B. in einer vorgefertigten Weise, wobei dann in den Kunststoff entsprechend die Kontaktelemente eingebracht werden. Auch hier sind beliebige Längen des auf diese Weise gebildeten rasterförmigen Gerippes möglich.The elastic wrap 14 may be e.g. be introduced or introduced as plastic by injection molding. Of course, the elastic covering may also be applied in other ways, e.g. in a prefabricated manner, in which case the contact elements are introduced into the plastic accordingly. Again, any lengths of the grid-shaped ridges formed in this way are possible.

Das rasterförmige Gerippe 10 wird in nicht näher dargestellter Weise, z.B. durch Verkleben, mit einer Pressbrücke 16 auf seiner Rückseite verbunden. Anstelle eines rasterförmigen Gerippes können selbstverständlich im Rahmen der Erfindung auch andere Ausgestaltungen vorgesehen werden. Wesentlich ist lediglich, dass eine Vielzahl von Kontaktelementen 3 rasterartig hintereinander in einer elastischen Umhüllung angeordnet sind.The grid-shaped frame 10 is in a manner not shown, for example by gluing, with a press bridge 16th connected on its back. Instead of a grid-shaped skeleton, other embodiments may of course be provided within the scope of the invention. It is only essential that a plurality of contact elements 3 are arranged like a grid in succession in an elastic envelope.

Die Pressbrücke 16 kann elastisch und leicht konkav als Gummibrücke ausgebildet sein und ist entsprechend in dem Gebergehäuse 12 zwischen den beiden Magnetkörpern 4 angeordnet, womit sie sich über die gesamte Länge des rasterförmigen Gerippes 10 erstreckt.The pressing bridge 16 may be formed elastically and slightly concave as a rubber bridge and is arranged correspondingly in the encoder housing 12 between the two magnetic bodies 4, whereby it extends over the entire length of the grid-shaped skeleton 10.

Durch die elastische Umhüllung 14, die Luftspalte 12 und die Pressbrücke 16 wird beim Verbinden der Stromgebereinrichtung 1 mit der Stromabnahmeeinrichtung 5 ein sicherer Flächenkontakt für alle Kontaktelemente 3 mit den Kontaktelementen 9 der Stromabnahmeeinrichtung 5 erreicht. Die elastische Umhüllung 14 kann auch für eine feuchtigkeits- bzw. wasserdichte Verbindung sorgen. Gleichzeitig dient sie als Korsett für die Kontaktelemente 3 bei Beibehaltung einer Elastizität.By the elastic sheath 14, the air gaps 12 and the pressing bridge 16, a secure surface contact for all contact elements 3 with the contact elements 9 of the current collection device 5 is achieved when connecting the power supply device 1 with the current collection device 5. The elastic sheath 14 can also provide a moisture or water-tight connection. At the same time it serves as a corset for the contact elements 3 while maintaining elasticity.

Wie ersichtlich, ist dies dabei unabhängig von der Anzahl der nebeneinander angeordneten Kontaktelementen 3 bzw. 9.As can be seen, this is independent of the number of juxtaposed contact elements 3 and 9.

Bei dem vorliegenden Ausführungsbeispiel wurden die Kontaktelemente 3 der Stromgebereinrichtung 1 als elastisch in dem rasterförmigen Gerippe 10 angeordnet beschrieben. Selbstverständlich ist es im Rahmen der Erfindung klar, dass als Alternative dazu auch die Stromabnahmeeinrichtung 5 mit entsprechend elastisch angeordneten Kontaktelementen 9 versehen sein kann, während die Kontaktelemente 3 der Stromgebereinrichtung 1 fest in dem Gebergehäuse 2 angeordnet sind. Ebenso ist es auch möglich, alle Kontaktelemente 3 und 9 elastisch in rasterförmigen Gerippen 10 zu lagern.In the present embodiment, the contact elements 3 of the current-carrying device 1 have been described as being arranged elastically in the grid-shaped frame 10. Of course, it is clear in the context of the invention that as an alternative to the current collection device 5 with correspondingly elastically arranged contact elements 9 may be provided while the contact elements 3 of the power supply device 1 are fixedly arranged in the transmitter housing 2. Likewise, it is also possible to elastically store all contact elements 3 and 9 in grid-like ribs 10.

Wie aus der Fig. 2 ersichtlich ist, können die Kontaktelemente 9, ebenso jedoch auch die Kontaktelemente 3, in Form von dünnen Scheiben mit seitlichen Verlängerungen 17 ausgebildet sein. Über die seitlichen Verlängerungen 17 erfolgt dann über Zu- bzw. Ableitungen 18 die Stromzuführung bzw. Stromweiterleitung zu einem nicht dargestellten Verbraucher.Like from the Fig. 2 it can be seen, the contact elements 9, as well as the contact elements 3, in the form of thin disks with lateral extensions 17 may be formed. About the lateral extensions 17 then takes place via supply and discharge lines 18, the power supply or power transmission to a consumer, not shown.

Das rasterförmige Gerippe 10 kann aus einem elastischen Kunststoffteil gebildet sein. Für die Kontaktelemente 3 bzw. 9 lassen sich Messingteile, evtl. versilbert, als einfache Stanzteile verwenden.The grid-shaped frame 10 may be formed of a resilient plastic part. For the contact elements 3 and 9, brass parts, possibly silver plated, can be used as simple stamped parts.

Zur genauen mechanischen Zuführung bzw. Verbindung der Stromgebereinrichtung 1 mit der Stromabnahmeeinrichtung 5 kann die Stromgebereinrichtung 1 mit ein oder mehreren konusartigen Aussparungen 19 versehen sein, an deren unteren Ende jeweils ein Magnetkörper 4 liegt. Umgekehrt weist die Stromabnahmeeinrichtung 5 ein oder mehrere konusartige Erweiterungen 20 auf, die an die Konuswinkel der konusartigen Aussparungen 19 angepasst sind. In jeder konusartigen Erweiterung 20 befindet sich jeweils ein Magnetkörper 7. Zur elektrischen Verbindung werden die konusartigen Erweiterungen 20 entsprechend in die konusartigen Aussparungen 19 selbstzentrierend eingeführt, wobei am Ende der Einführung die Magnetkörper 4 und 7 aufeinander liegen und dabei die Kontaktverbindungen zwischen den Kontaktelementen 3 und 9 stabil und sicher herstellen. Durch diese Ausgestaltung wird praktisch eine "blinde" Kontaktierung der Kontaktelemente 3 und 9 ohne Fehlermöglichkeit erreicht.For the exact mechanical supply or connection of the current-carrying device 1 to the current-collecting device 5, the current-carrying device 1 can be provided with one or more conical recesses 19, at whose lower end a respective magnetic body 4 is located. Conversely, the current collection device 5 has one or more conical extensions 20, which are adapted to the cone angle of the conical recesses 19. In each cone-like extension 20 is in each case a magnetic body 7. For electrical connection, the cone-like extensions 20 are introduced in accordance self-centering in the cone-like recesses 19, wherein at the end of the introduction, the magnetic body 4 and 7 lie on each other and thereby the contact connections between the contact elements 3 and 9 stable and make sure. As a result of this configuration, a "blind" contacting of the contact elements 3 and 9 is achieved without possibility of error.

Wenn sehr hohe Ströme übertragen werden sollen, kann man zwei nebeneinander liegende Kontaktelemente 3 durch eine leitende Kontaktbrücke 21 miteinander verbinden. (siehe gestrichelte Darstellung in Fig. 1). Gleiches gilt dann für die damit zusammenarbeitenden Kontaktelemente 9. Eine Kontaktbrücke 21 kann auch für die Fälle verwendet werden, bei denen von einem gemeinsamen Eingangsstrom auf zwei (oder mehrere, bei längeren Kontaktbrücken) gleiche Ausgangsströme oder umgekehrt weitergeleitet werden soll.If very high currents are to be transmitted, two adjacent contact elements 3 can be connected to one another by a conductive contact bridge 21. (see dashed line in FIG Fig. 1 ). The same applies then to the contact elements 9 cooperating therewith. A contact bridge 21 can also be used for cases in which the same output currents or vice versa are to be forwarded from a common input current to two (or more, for longer contact bridges).

Eine weitere Sicherheit gegen fehlerhafte Verbindungen bzw. eine Kontaktierung von nicht zueinander passenden Stromgebereinrichtungen 1 mit Stromabnahmeeinrichtungen 5 wird erreicht, wenn die Magnetkörper 4 und 7 "kodiert" ausgebildet sind. Mit "kodiert" ausgebildet ist gemeint, dass jeder Magnetkörper aus mehreren Einzelmagnetteilchen unterschiedlicher Polarität zusammengesetzt ist, wobei die sich gegenüberliegenden Magnetkörper 7 und 4 jeweils gegenpolig angeordnet sind. Eine derartige Kodierung ist z.B. aus der WO 01/03249 A1 in Fig. 3 ersichtlich. Auch in der EP 0 573 471 (12.10.94) sind derart kodierte Magnete beschrieben. Auf diese Weise kann eine Kontaktverbindung nur dann erfolgen, wenn die richtig kodierten Magnete aufeinandertreffen.A further security against faulty connections or a contacting of mismatching power supply devices 1 with power take-off devices 5 is achieved when the magnetic bodies 4 and 7 are "coded" formed. By "coded" is meant that each magnetic body is composed of a plurality of individual magnetic particles of different polarity, wherein the opposing magnetic bodies 7 and 4 are each arranged opposite to each other. Such a coding is for example from the WO 01/03249 A1 in Fig. 3 can be seen. Also in the EP 0 573 471 (12.10.94) magnets coded in this way are described. In this way, a contact connection can only take place when the correctly coded magnets meet.

Das vorstehend beschriebene Ausführungsbeispiel ist in Kombination mit den Magnetkörpern 4 und 7 beschrieben. Selbstverständlich können die Magnetkörper 4 und 7 im Bedarfsfalle auch entfallen und nach einem Aufsetzen der Stromabnahme- oder Datenabnahmeeinrichtung auf die Strom- oder Datengebereinrichtung kann eine Verbindung bzw. Haltekraft zwischen den beiden Einrichtungen auch auf andere Weise durchgeführt werden, wie z.B. Verriegelungen oder Verrastungen.The embodiment described above is described in combination with the magnetic bodies 4 and 7. Of course, the magnetic body 4 and 7 can also be omitted in case of need and after setting up the power take-off or data collection device to the power or data supply device, a connection or holding force between the two devices can also be performed in other ways, such as locks or latches.
