  • wobei der Schalter im Baugruppengehäuse angeordnet ist,
  • wobei der Zuführkontakt und der erste Weiterleitungskontakt über den Schalter und der Rückführkontakt und der zweite Weiterleitungskontakt direkt miteinander verbunden sind,
  • wobei der Zuführkontakt und der Rückführkontakt Bestandteile einer ersten und die Weiterleitungskontakte Bestandteile einer zweiten vorkonfektionierten Steckverbindung sind,
  • wobei die Steckverbindungen von außerhalb des Baugruppengehäuses zugänglich sind und derart ausgebildet sind, dass die erste Steckverbindung einer ersten erfindungsgemäßen Baugruppe mit der zweiten Steckverbindung einer zweiten erfindungsgemäßen Baugruppe zusammensteckbar ist,
  • wobei durch das Zusammenstecken der Steckverbindungen je einer der Weiterleitungskontakte der zweiten Baugruppe mit dem Zuführkontakt und dem Rückführkontakt der ersten Baugruppe verbunden werden.
The present invention relates to an assembly comprising an assembly housing, a switch, a feed contact, a return contact and a first and a second relay contact,
  • wherein the switch is disposed in the package housing,
  • wherein the feed contact and the first relay contact are directly connected via the switch and the return contact and the second relay contact,
  • wherein the supply contact and the return contact are components of a first and the forwarding contacts components of a second prefabricated connector,

Derartige Baugruppen sind bekannt.Such assemblies are known.

Im Rahmen der Sicherheitstechnik werden oftmals mittels Schaltern sicherheitsrelevante Schaltzustände von Baugruppen erfasst und überwacht. In manchen Fällen ist es hierbei zulässig, die Schalter der Baugruppen elektrisch in Reihe zu schalten.As part of safety technology, safety-related switching states of modules are often detected and monitored by means of switches. In some cases, it is permissible to connect the switches of the modules electrically in series.

Im Stand der Technik ist bekannt, die Schalter einzeln manuell zu verdrahten. Diese Vorgehensweise ist mühsam, umständlich und fehlerträchtig.It is known in the prior art to manually wire the switches individually. This approach is cumbersome, cumbersome and error prone.

Baugruppen der obenstehend beschriebenen Art stellen bereits einen erheblichen Fortschritt dar, da der Serienkreis in diesem Fall durch das Zusammenstecken der ersten und der zweiten Steckverbindung automatisch verlängert wird. Auch bei dieser Ausgestaltung ist es jedoch erforderlich, den Serienkreis zu schließen, das heißt die Weiterleitungskontakte der letzten Baugruppe elektrisch leitend miteinander zu verbinden.Assemblies of the type described above already represent a significant advance, since the series circuit is automatically extended in this case by the mating of the first and the second connector. However, in this embodiment, too, it is necessary to close the series circuit, that is, to connect the relay contacts of the last module to one another in an electrically conductive manner.

Die Aufgabe der vorliegenden Erfindung besteht darin, eine Baugruppe der eingangs genannten Art derart auszugestalten, dass der vollständige Serienkreis automatisch gebildet wird.The object of the present invention is to design an assembly of the type mentioned in such a way that the complete series circuit is automatically formed.

Die Aufgabe wird bei einer Baugruppe der eingangs genannten Art dadurch gelöst,

  • dass die Baugruppe zusätzlich eine Schalteinrichtung sowie ein erstes und ein zweites Betätigungselement aufweist,
  • dass die Schalteinrichtung im Baugruppengehäuse angeordnet ist,
  • dass das erste Betätigungselement Bestandteil der ersten und das zweite Betätigungselement Bestandteil der zweiten Steckverbindung sind und
  • dass durch das Zusammenstecken der Steckverbindungen das erste Betätigungselement der ersten Baugruppe derart auf das zweite Betätigungselement der zweiten Baugruppe einwirkt, dass die Schalteinrichtung der zweiten Baugruppe einen Strompfad vom ersten zum zweiten Weiterleitungskontakt der zweiten Baugruppe unterbricht.
The object is achieved in an assembly of the type mentioned, characterized
  • the assembly additionally has a switching device and a first and a second actuating element,
  • that the switching device is arranged in the module housing,
  • that the first actuating element is part of the first and the second actuating element part of the second connector and
  • in that the first actuating element of the first module acts on the second actuating element of the second module as a result of the mating of the plug-in connections, that the switching device of the second module interrupts a current path from the first to the second relay contact of the second module.

Im einfachsten Fall ist die Schalteinrichtung als mechanische Schalteinrichtung ausgebildet und sind die Betätigungselemente als mechanische Betätigungselemente ausgebildet. Alternativ ist es jedoch möglich, dass die Schalteinrichtung als elektronische Schalteinrichtung ausgebildet ist und die Betätigungselemente als elektrisch zusammenwirkende Kontakte ausgebildet sind.In the simplest case, the switching device is designed as a mechanical switching device and the actuating elements are designed as mechanical actuating elements. Alternatively, however, it is possible that the switching device is designed as an electronic switching device and the actuating elements are designed as electrically cooperating contacts.

Das Baugruppengehäuse ist oftmals quaderförmig ausgebildet. Bei einer derartigen Ausgestaltung ist es von Vorteil, wenn die Steckverbindungen derart angeordnet sind, dass die erste Steckverbindung der ersten Baugruppe und die zweite Steckverbindung der zweiten Baugruppe beim Ansetzen der ersten Baugruppe an die zweite Baugruppe automatisch zusammengesteckt werden.The module housing is often cuboid. In such an embodiment, it is advantageous if the connectors are arranged such that the first connector of the first module and the second connector of the second module are automatically assembled when attaching the first module to the second module.

Wenn die Baugruppe ein Schütz aufweist, wird vorzugsweise der Schalter durch das Ansteuern des Schützes geöffnet. In diesem Fall ist das Schütz der Baugruppe auf ordnungsgemäßes Abfallen im ansteuerfreien Zustand überwachbar.If the module has a contactor, the switch is preferably opened by the activation of the contactor. In this case, the contactor of the module can be monitored for proper dropout in the drive-free state.

Die Baugruppe kann als Motorabzweig ausgebildet sein. Diese Ausgestaltung stellt einen häufigen Anwendungsfall dar.The module can be designed as a motor branch. This embodiment represents a frequent application.

Weitere Vorteile und Einzelheiten ergeben sich aus der nachfolgenden Beschreibung von Ausführungsbeispielen in Verbindung mit den Zeichnungen. Es zeigen in Prinzipdarstellung:

Further advantages and details will become apparent from the following description of exemplary embodiments in conjunction with the drawings. In a schematic representation:

FIG. 5

Gemäß FIG 1 weist eine Anordnung mehrere Baugruppen 1, 2, 3 auf, beispielsweise mehrere Motorabzweige 1, eine Stromversorgungsbaugruppe 2 und eine Steuerbaugruppe 3. Die Motorabzweige 1 sind über ein Einspeiseschütz 4 und einen dem Einspeiseschütz 4 vorgeordneten Leistungsschalter 5 mit einem Drehstromnetz 6 verbunden. Sie werden von der Steuerbaugruppe 3 angesteuert, so dass sie - je nach Ansteuerzustand - elektrische Motoren 7 an das Drehstromnetz 6 anschalten oder nicht. Die Stromversorgungsbaugruppe 2 stellt den Motorabzweigen 1 Hilfsspannungen zur Verfügung, welche die Motorabzweige 1 im Betrieb benötigen.According to FIG. 1 has an arrangement of a plurality of modules 1, 2, 3, for example, several motor branches 1, a power supply module 2 and a control module 3. The motor branches 1 are connected via a feed contactor 4 and a power contactor 4 upstream power switch 5 with a three-phase network 6. They are controlled by the control module 3, so that they - depending on the driving state - turn on electric motors 7 to the three-phase network 6 or not. The power supply module 2 provides the motor branches 1 auxiliary voltages that require the motor branches 1 in operation.

Die Motorabzweige 1 weisen intern unter anderem einen Kurzschlusstrenner, einen Überstromschutz sowie ein Schaltschütz 8 auf. Der Kurzschlusstrenner und der Überstromschutz können beispielsweise zu einem üblichen Leistungsschalter 9 zusammengefasst sein. Das Schaltschütz 8 ist von der Steuerbaugruppe 3 ansteuerbar. Sein Ansteuerzustand bestimmt bei ordnungsgemäßem Funktionieren der Gesamtschaltung des jeweiligen Motorabzweigs 1, ob der jeweilige Motor 7 an das Drehstromnetz 6 angeschaltet ist oder nicht.Among other things, the motor branches 1 have inter alia a short-circuit disconnector, an overcurrent protection and a contactor 8 on. The short-circuit disconnector and the overcurrent protection can be combined, for example, to form a conventional circuit breaker 9. The contactor 8 can be controlled by the control module 3. Its drive state determines, with proper functioning of the overall circuit of the respective motor branch 1, whether the respective motor 7 is connected to the three-phase network 6 or not.

Bei sicherheitsgerichteten Anwendungen muss der tatsächliche Schaltzustand des Schaltschützes 8 erfasst werden, damit beispielsweise das Einspeiseschütz 4 geöffnet werden kann, wenn Hauptkontakte 10 des Schaltschützes 8 verschweißt sind. Zu diesem Zweck ist dem Schaltschütz 8 ein Hilfskontakt 11 zugeordnet, der zusammen mit den Hauptkontakten 10 des Schaltschützes 8 betätigt wird. Der Hilfskontakt 11 entspricht einem Schalter 11 im Sinne der vorliegenden Erfindung. Er ist vorzugsweise als Öffner ausgebildet, wird also durch das Ansteuern des Schaltschützes 8 geöffnet. Sein Schaltzustand wird von der Steuerbaugruppe 3 überwacht. Hierzu ist der Hilfskontakt 11 in einen baugruppenübergreifenden Überwachungskreis eingeschleift. Die Art und Weise, wie dieser Überwachungskreis gebildet wird, ist Kerngegenstand der vorliegenden Erfindung. Der Kerngegenstand wird nachfolgend in Verbindung mit FIG 2 näher erläutert.For safety-related applications, the actual switching state of the contactor 8 must be detected so that, for example, the feed-in contactor 4 can be opened when main contacts 10 of the contactor 8 are welded. For this purpose, the contactor 8 is associated with an auxiliary contact 11 which is actuated together with the main contacts 10 of the contactor 8. The auxiliary contact 11 corresponds to a switch 11 in the sense of the present invention. It is preferably designed as an opener, so it is opened by the driving of the contactor 8. Its switching state is monitored by the control module 3. For this purpose, the auxiliary contact 11 is looped into a cross-module monitoring circuit. The manner in which this monitoring circuit is formed is the core of the present invention. The core article will be described below in connection with FIG. 2 explained in more detail.

In FIG 2 sind eine erste und eine zweite erfindungsgemäße Baugruppe 1, 1' dargestellt. Soweit es den Aufbau der einzelnen Baugruppen 1, 1' betrifft, wird nachfolgend nur der Aufbau der ersten Baugruppe 1 näher erläutert. Die zweite Baugruppe 1' ist - soweit es den Gegenstand der vorliegenden Erfindung betrifft - analog ausgebildet. Die Elemente der zweiten Baugruppe 1' sind daher mit den gleichen Bezugszeichen versehen wie die jeweils korrespondierenden Elemente der ersten Baugruppe 1, jedoch zusätzlich mit einem Apostroph.In FIG. 2 are a first and a second inventive assembly 1, 1 'shown. As far as the structure of the individual modules 1, 1 'is concerned, only the structure of the first module 1 will be explained in more detail below. The second module 1 'is - as far as the object of the present invention is concerned - formed analog. The elements of the second assembly 1 'are therefore provided with the same reference numerals as the respective corresponding elements of the first assembly 1, but in addition with an apostrophe.

Gemäß FIG 2 weist die erste Baugruppe 1 ein Baugruppengehäuse 12, den Schalter 11, einen Zuführkontakt 13, einen Rückführkontakt 14, einen ersten Weiterleitungskontakt 15 und einen zweiten Weiterleitungskontakt 16 auf. Die Baugruppe 1 weist weiterhin eine Schalteinrichtung 17, ein erstes Betätigungselement 18 und ein zweites Betätigungselement 19 auf. Der Schalter 11 entspricht, wie bereits erwähnt, dem Hilfskontakt 11 des Schaltschützes 8. Er ist im Baugruppengehäuse 12 angeordnet. Auch die Schalteinrichtung 17 ist im Baugruppengehäuse 12 angeordnet.According to FIG. 2 For example, the first module 1 has a module housing 12, the switch 11, a feed contact 13, a return contact 14, a first relay contact 15 and a second forwarding contact 16. The assembly 1 further comprises a switching device 17, a first actuating element 18 and a second actuating element 19. The switch 11 corresponds, as already mentioned, the auxiliary contact 11 of the contactor 8. It is arranged in the assembly housing 12. The switching device 17 is arranged in the module housing 12.

Der Zuführkontakt 13 und der erste Weiterleitungskontakt 15 sind über den Schalter 11 miteinander verbunden. Der Rückführkontakt 14 und der zweite Weiterleitungskontakt 16 sind direkt miteinander verbunden. Der Zuführkontakt 13, der Rückführkontakt 14 und das erste Betätigungselement 18 sind Bestandteile einer ersten vorkonfektionierten Steckverbindung 20. Die Weiterleitungskontakte 15, 16 und das zweite Betätigungselement 19 sind Bestandteile einer zweiten vorkonfektionierten Steckverbindung 21.The feed contact 13 and the first relay contact 15 are connected to each other via the switch 11. The return contact 14 and the second relay contact 16 are connected directly to each other. The feed contact 13, the return contact 14 and the first actuating element 18 are components of a first prefabricated plug connection 20. The forwarding contacts 15, 16 and the second actuating element 19 are components of a second prefabricated plug connection 21.

Die Steckverbindungen 20, 21 sind von außerhalb des Baugruppengehäuses 12 zugänglich. Sie sind derart ausgebildet, dass die erste Steckverbindung 20 der ersten Baugruppe 1 mit der zweiten Steckverbindung 21' der zweiten Baugruppe 1' zusammensteckbar ist. Dies ist sehr deutlich aus den FIG 3 bis 5 ersichtlich.The connectors 20, 21 are accessible from outside the module housing 12. They are designed such that the first connector 20 of the first module 1 with the second connector 21 'of the second module 1' is plugged together. This is very clear from the 3 to 5 seen.

Durch das Zusammenstecken der ersten Steckverbindung 20 der ersten Baugruppe 1 und der zweiten Steckverbindung 21' der zweiten Baugruppe 1' wird zunächst der erste Weiterleitungskontakt 15' der zweiten Baugruppe 1' mit dem Zuführkontakt 13 der ersten Baugruppe 1 verbunden. Weiterhin wird durch das Zusammenstecken.der zweite Weiterleitungskontakt 16' der zweiten Baugruppe 1' mit dem Rückführkontakt 14 der ersten Baugruppe 1 verbunden. Schließlich wirkt das erste Betätigungselement 18 der ersten Baugruppe 1 auf das zweite Betätigungselement 19' der zweiten Baugruppe 1' ein. Die Einwirkung ist derart, dass die Schalteinrichtung 17' der zweiten Baugruppe 1' einen Strompfad 22' unterbricht, der sich vom ersten zum zweiten Weiterleitungskontakt 15', 16' der zweiten Baugruppe 1' erstreckt.By the mating of the first connector 20 of the first module 1 and the second connector 21 'of the second module 1', the first relay contact 15 'of the second module 1' is first connected to the Zuführkontakt 13 of the first module 1. Furthermore, by plugging together the second relay contact 16 'of the second module 1' is connected to the feedback contact 14 of the first module 1. Finally, the first actuating element 18 of the first module 1 acts on the second actuating element 19 'of the second module 1'. The action is such that the switching device 17 'of the second module 1' interrupts a current path 22 ', which differs from the first to the second relay contact 15 ', 16' of the second module 1 'extends.

Die Schalteinrichtung 17 der zweiten Baugruppe 1' kann beispielsweise als mechanische Schalteinrichtung ausgebildet sein. In diesem Fall ist die Schalteinrichtung 17' ein einfacher Öffner, der durch das zweite Betätigungselement 19' der zweiten Baugruppe 1' geöffnet wird, wenn das erste Betätigungselement 18 der ersten Baugruppe 1 auf das zweite Betätigungselement 19' der zweiten Baugruppe 1' einwirkt.The switching device 17 of the second module 1 'may be formed, for example, as a mechanical switching device. In this case, the switching device 17 'is a simple opener, which is opened by the second actuating element 19' of the second module 1 'when the first actuating element 18 of the first module 1 acts on the second actuating element 19' of the second module 1 '.

Alternativ kann die Schalteinrichtung 17' als elektronische Schalteinrichtung ausgebildet sein. Die Betätigungselemente 18, 19' sind in diesem Fall als elektrisch zusammenwirkende Kontakte ausgebildet. Beispielsweise kann das Betätigungselement 18 der ersten Baugruppe 1 als Kontaktbrücke ausgebildet sein, das Betätigungselement 19' der zweiten Baugruppe 1' als Kontaktpaar. Das Stecken der Steckverbindungen 20, 21' bewirkt in diesem Fall das Schließen eines Stromkreises. Das Schließen des Stromkreises bewirkt, dass das elektronische Schaltelement 17' hochohmig geschaltet wird. Auch andere Ausgestaltungen (z. B. Unterbrechen einer Lichtschranke oder Herstellen einer induktiven Kopplung) sind möglich.Alternatively, the switching device 17 'may be formed as an electronic switching device. The actuators 18, 19 'are formed in this case as electrically cooperating contacts. For example, the actuating element 18 of the first module 1 can be designed as a contact bridge, the actuating element 19 'of the second module 1' as a contact pair. The insertion of the connectors 20, 21 'causes in this case the closing of a circuit. The closing of the circuit causes the electronic switching element 17 'is switched high impedance. Other configurations (eg interrupting a light barrier or producing an inductive coupling) are also possible.

Gemäß der in den FIG 3 bis 5 dargestellten bevorzugten Ausgestaltung ist das Baugruppengehäuse 12 quaderförmig ausgebildet. Die Steckverbindungen 20, 21 sind derart angeordnet, dass die erste Steckverbindung 20 der ersten Baugruppe 1 und die zweite Steckverbindung 21' der zweiten Baugruppe 1' beim Ansetzen der ersten Baugruppe 1 an die zweite Baugruppe 1' automatisch zusammengesteckt werden. Beispielsweise kann entsprechend der Darstellung der FIG 3 und 5 die zweite Steckverbindung 21 in einem Vorsprung 23 angeordnet sein, der auf einer Seite des Baugruppengehäuses 12 angeordnet ist. Die erste Steckverbindung 20 ist in diesem Fall entsprechend der Darstellung der FIG 4 und 5 in einer Einbuchtung 24 angeordnet, die auf einer zweiten Seite des Baugruppengehäuses 12 angeordnet ist. Die erste und die zweite Seite liegen hierbei einander gegenüber.
