Im Informationstechnik- und Kommunikationstechnikbereich ist bereits der Einsatz konfektionierter Chips zur Realisierung von Zählerfunktionen und von Informationsspeichern zur Überprüfung von Zugangsberechtigungen für physikalische Resourcen bekannt. Dabei dienen die Chipkarten im wesentlichen der Speicherung von benutzerspezifischen Daten für eine bestimmte physikalische Resource, ohne dabei die Funktionalität der physikalischen Resource grundlegend zu verändern. Hauptsächlich werden in Abhängigkeit von einem bestimmten Benutzerprofil die durch eine physikalische Resource zur Verfügung ge- stellten Funktionalitäten entsprechend den auf der Chipkarte gespeicherten Informationen eingeschränkt. Eine derartige Kontrollvorrichtung ist beispielsweise aus EP 0 818 722 AI bekannt. Durch die auf der Chipkarte gespeicherten Informationen erfolgt dort keine grundlegende strukturelle Verände- rung von Aufbau und Funktionsweise der zu überwachenden physikalischen Resource. Insbesondere bei verhältnismäßig einfachen Aktoren - beispielsweise Relais - sind keine Vorrichtungen oder Verfahren zur Modifikation ihrer Funktionalitäten bekannt .In the field of information technology and communication technology, the use of ready-made chips for implementing counter functions and information stores for checking access authorizations for physical resources is already known. The chip cards essentially serve to store user-specific data for a specific physical resource, without fundamentally changing the functionality of the physical resource. Mainly depending on a specific user profile, the functionalities made available by a physical resource are restricted in accordance with the information stored on the chip card. Such a control device is known for example from EP 0 818 722 AI. Due to the information stored on the chip card, there is no fundamental structural change in the structure and functioning of the physical resource to be monitored. In particular with relatively simple actuators - for example relays - no devices or methods for modifying their functionalities are known.

Der große Vorteil des erfindungsgemäßen Relais liegt in der hohen Flexibilität bei der Fertigung, da die Grundkomponenten des Relais, wie Magnetsystem, Kontaktsystem, Anschlußelemente und Gehäuse für mehrere unterschiedliche Relaistypen verwendet werden können. Die einzelnen Relaistypen unterscheiden sich untereinander lediglich durch voneinander abweichende, durch die auswechselbaren Chipkarten implementierte Schaltungsfunktionen. Je nach applikationsspezifischen Anforderungen oder Kundenwünschen können auf einfache Weise individuelle Relaistypen realisiert werden, die weitgehend in einer gemeinsamen Fertigungslinie für mehrere Relaistypen einer Pro- duktlinie hergestellt werden. Hieraus resultiert eine deutliche Kostenreduktion.The great advantage of the relay according to the invention lies in the high flexibility in production, since the basic components of the relay, such as the magnet system, contact system, connection elements and housing, can be used for several different relay types. The individual relay types differ from one another only by different circuit functions implemented by the interchangeable chip cards. Depending on the application-specific requirements or customer requirements, individual relay types can be easily implemented, which are largely manufactured in a common production line for several relay types of a product line. This results in a significant cost reduction.
Es ist möglich, daß die Chipkarte ausschließlich passive elektronische Bauelemente aufweist. Je nach Anwendung kann jedoch notwendig sein, daß die Chipkarte sowohl passive als auch aktive elektronische Bauelemente aufweist (Smart Card) . Hiermit lassen sich beispielsweise Diagnoseschaltungen, Zeit-
relais und Relais-Rechner-Kombinationen realisieren. In einer vorteilhaften Ausgestaltung der Erfindung ist durch die auf der Chipkarte angeordneten elektronischen Bauelemente eine Kurzschluß- und Überlaststromüberwachungseinheit gebildet. In einer besonders bevorzugten Ausführungsform ist durch die auf der Chipkarte angeordneten elektronischen Bauelemente zusätzlich eine Kurzschluß- und Uberlaststrombegrenzungseinheit gebildet.It is possible that the chip card has only passive electronic components. Depending on the application, however, it may be necessary for the chip card to have both passive and active electronic components (smart card). This allows, for example, diagnostic circuits, time Realize relays and relay-computer combinations. In an advantageous embodiment of the invention, a short-circuit and overload current monitoring unit is formed by the electronic components arranged on the chip card. In a particularly preferred embodiment, a short circuit and overload current limiting unit is additionally formed by the electronic components arranged on the chip card.
Für die Integration der Chipkarten-Schnittstelle bestehen mehrere Möglichkeiten. Die Chipkarten-Schnittstelle kann in eine Kappe eines Relaisgehäuses integriert sein, welche eine Aufnahme für die Chipkarte bildet. Außerdem ist es möglich, daß die Chipkarten-Schnittstelle in einen Relaissockel inte- griert ist, welcher eine Aufnahme für die Chipkarte aufweist.There are several options for integrating the chip card interface. The chip card interface can be integrated in a cap of a relay housing, which forms a receptacle for the chip card. It is also possible for the chip card interface to be integrated in a relay base which has a receptacle for the chip card.

Es zeigt Figur 1 ein erfindungsgemäßes Relais mit einer unbestückten Chipkarten-Schnittstelle,The invention is explained in more detail below using exemplary embodiments with reference to the drawing. 1 shows a relay according to the invention with an unequipped chip card interface,
Figur 2 eine auswechselbare Chipkarte, mit welcher die Chipkarten-Schnittstelle des Relais gemäß Figur 1 bestückbar ist und Figur 3 das Relais gemäß Figur 1, dessen Chipkarten-Schnitt- stelle mit einer Chipkarte gemäß Figur 2 bestückt ist.FIG. 2 shows an exchangeable chip card with which the chip card interface of the relay according to FIG. 1 can be fitted, and FIG. 3 the relay according to FIG. 1, the chip card interface of which is equipped with a chip card according to FIG.
Das Relais gemäß Figur 1 weist eine Kappe 5 auf, welche zusammen mit einem Sockel, aus dessen Bodenseite Wicklungsanschlußelemente 1 und Anschlußelemente 2 für bewegliche und feststehende Kontaktelemente heraustreten, ein Relaisgehäuse bildet. Durch die Kappe 5 sind zwei Erregerspulen und ein Kontaktsatz, welcher die feststehenden und beweglichen Kontaktelemente aufweist, sowie ein mechanisch mit den beweglichen Kontaktelementen gekoppelter Anker verdeckt.The relay according to FIG. 1 has a cap 5, which together with a base, from the bottom side of which winding connection elements 1 and connection elements 2 for movable and fixed contact elements emerge, forms a relay housing. The cap 5 covers two excitation coils and a contact set, which has the fixed and movable contact elements, and an armature mechanically coupled to the movable contact elements.
Hinsichtlich einer expliziten Darstellung des Relaisinnenlebens wird auf DE 196 02 642 AI verwiesen. Das dort beschrie-
bene Relais besitzt einen Grundkörper, in welchem an einem Ende eine Kontaktanordnung verankert ist, während am anderen Ende ein Magnetsystem mit einer Spule, einem Kern, einem Joch und einem Anker montiert wird, wobei die Ankerbewegung über einen Schieber auf die Kontaktanordnung übertragen wird.With regard to an explicit representation of the interior of the relay, reference is made to DE 196 02 642 AI. That described there bene relay has a base body in which a contact arrangement is anchored at one end, while a magnet system with a coil, a core, a yoke and an armature is mounted at the other end, the armature movement being transmitted to the contact arrangement via a slide.
Ferner ist in die in Figur 1 dargestellte Kappe 5 des Relaisgehäuses eine Chipkarten-Schnittstelle 3 integriert, welche eine Aufnahme für eine in Figur 2 dargestellte Chipkarte 4 bildet. Die Chipkarte 4 weist Kontaktzonen 6 auf, welche mit auf der auswechselbaren Chipkarte 4 angeordneten elektronischen Bauelementen verbunden sind. Den Kontaktzonen 6 an der Chipkarte 4 stehen Gegenkontaktelemente 7 an der Chipkarten-Schnittstelle 3 gegenüber, welche mit den Bauelementen des Erreger- bzw. Lastkreises des Relais gekoppelt sind. Durch die auf der Chipkarte 4 angeordneten elektronischen Bauelemente können beispielsweise eine Kurzschluß- und Über- laststromüberwachungseinheit sowie eine Kurzschluß- und Überlaststrombegrenzungseinheit gebildet sein.Furthermore, a chip card interface 3 is integrated in the cap 5 of the relay housing shown in FIG. 1, which forms a receptacle for a chip card 4 shown in FIG. The chip card 4 has contact zones 6 which are connected to electronic components arranged on the exchangeable chip card 4. The contact zones 6 on the chip card 4 are opposed by counter-contact elements 7 on the chip card interface 3, which are coupled to the components of the excitation or load circuit of the relay. The electronic components arranged on the chip card 4 can, for example, form a short-circuit and overload current monitoring unit and a short-circuit and overload current limiting unit.
In Figur 3 ist das Relais gemäß Figur 1 dargestellt, dessen Chipkarten-Schnittstelle 3 mit der Chipkarte 4 gemäß Figur 2 bestückt ist. Für die Funktion des Relais ist es jedoch nicht unbedingt erforderlich, daß die Chipkarten-Schnittstelle 3 mit einer Chipkarte 4 bestückt ist. Der Zustand unkontaktier- ter Gegenkontaktelemente 7 könnte in diesem Fall durch eine im Relais enthaltene interne Verschaltung entsprechend ausgewertet werden, wobei in diesem Falle die Funktionalität des Relais auf dessen Basisfunktion zu beschränken wäre.
FIG. 3 shows the relay according to FIG. 1, the chip card interface 3 of which is equipped with the chip card 4 according to FIG. 2. For the function of the relay, however, it is not absolutely necessary for the chip card interface 3 to be equipped with a chip card 4. In this case, the state of uncontacted mating contact elements 7 could be evaluated accordingly by an internal connection contained in the relay, in which case the functionality of the relay would have to be restricted to its basic function.
