Description

Die Erfindung bezieht sich auf ein Aufsatzgehäuse für elektromagnetische Schaltgeräte, das quer zur Frontseite geteilt und mit Anschlußdurchführungen für die Schutzbeschaltung des elektromagnetischen Schaltgerätes versehen ist.The invention relates to an add-on housing for electromagnetic switching devices, which is divided transversely to the front side and is provided with connecting bushings for the protective circuitry of the electromagnetic switching device.

Bei einem bekannten Aufsatzgehäuse der obengenannten Art (EP-A-0 189 924) ist in dem Aufsatzgehäuse eine Hilfsschalteranordnung vorgesehen, die es ermöglicht, die Anzahl der Hilfsschalter bei einem Schütz durch Aufsetzen des Gehäuses zu vergrößern. Um derartige elektromagnetische Schaltgeräte mit Zeitrelais zusammenschalten zu können, wurden diese bisher neben diesen angeordnet und getrennt verdrahtet. Der Erfindung liegt die Aufgabe zugrunde, eine Zeitrelaisbefestigung zu schaffen, die ohne weitere Montagefläche auskommt.In a known top housing of the type mentioned above (EP-A-0 189 924), an auxiliary switch arrangement is provided in the top housing, which makes it possible to increase the number of auxiliary switches in a contactor by fitting the housing. In order to be able to interconnect such electromagnetic switching devices with time relays, these have so far been arranged next to them and wired separately. The invention has for its object to provide a timing relay attachment that does not require any additional mounting surface.

Dies wird dadurch erreicht, daß in dem Aufsatzgehäuse zumindest eine parallel zur Frontseite in Nuten des Aufsatzgehäuses geführte Zeitrelaisplatine gehalten ist, die beim Einführen in die Nuten mit zumindest einem, mit ihr elektrisch und mechanisch verbundenen Lyrakontaktteil zumindest eine der Anschlußdurchführungen und/oder mit einem anderen Lyrakontaktteil mindestens einen Fortsatz einer Zeitrelaisanschlußklemme umgreift. Hierdurch ergibt sich weiterhin der Vorteil, daß durch die Beibehaltung der Anschlußdurchführungen der Anschluß von Bedämpfungsgliedern für die Schützspule, wie sie bei der Hilfsschalteranordnung üblich war, weiterhin möglich ist. Das Zeitrelais wird im allgemeinen in Reihe zur Spule des elektromagnetischen Schaltgerätes geschaltet. Da durch die Erfindung die Verbindung beim Aufsetzen des Gehäuses mehr oder weniger automatisiert wird, ist es von Vorteil, um Fehlanschlüsse zu vermeiden, wenn das Gehäuse mit einer Anformung versehen ist, die den einen Spulenanschluß des elektromagnetischen Schaltgerätes im aufgesetzten Zustand des Aufsatzgehäuses abdeckt. Um trotz des Aufbaus des Zeitrelais die Bedienung und Beobachtung des Schützes weiterhin ohne Schwierigkeiten zu ermöglichen, ist es von Vorteil, wenn in diesem ein die Frontseite mit einer Anformung durchdringender Schieber vorgesehen ist, der mit der Schaltstellungsanzeige des elektromagnetischen Schaltgerätes kuppelbar ist. Eine einfache Montage der Einstellelemente in bezug auf die Frontseite ergibt sich, wenn eine zweite Platine parallel zur Frontseite mit Einstellelementen vorgesehen ist, wobei die Einstellelemente die Frontseite zumindest teilweise durchdringen.This is achieved in that at least one timing relay board, which is guided parallel to the front in grooves of the top housing, is held in the top housing, which when inserted into the grooves with at least one, with it electrically and mechanically connected, Lyra contact part, at least one of the connection bushings and / or with another Lyra contact part encompasses at least one extension of a time relay connection terminal. This also has the advantage that the connection of attenuators for the contactor coil, as was customary in the auxiliary switch arrangement, is still possible by maintaining the connection bushings. The timing relay is generally connected in series with the coil of the electromagnetic switching device. Since the connection is more or less automated when the housing is put on by the invention, it is advantageous in order to avoid incorrect connections if the housing is provided with a molding which forms the one coil connection of the electromagnetic switching device in the attached state of the add-on housing. In order to continue to operate and monitor the contactor without difficulty despite the construction of the time relay, it is advantageous if a slider that penetrates the front side with a molding is provided in it, which can be coupled to the switch position indicator of the electromagnetic switching device. The adjustment elements can be easily installed with respect to the front side if a second circuit board with adjustment elements is provided parallel to the front side, the adjustment elements at least partially penetrating the front side.

Das in den FIG 1 bis 3 dargestellte elektromagnetische Schaltgerät oder Schütz 1 entspricht dem in der europäischen Patentschrift 0 189 924 dargestellten. Es besitzt an gegenüberliegenden Seiten die Anschlüsse 2 für die Kontakte und für den Spulenanschluß 3 und dazwischenliegend die entsprechenden Ausnehmungen für die Türme 4 und 5, die in den Abmessungen den Türmen der Hilfsschalteranordnung nach der europäischen Patentschrift entsprechen. Sie sind auch mit einer entsprechenden Verriegelungseinrichtung 6, die durch den Hebel 7 aufhebbar ist, ausgestattet. Das Aufsatzgehäuse 8 ist quer zur Frontseite zweigeteilt und besteht aus den Gehäusehälften 9 und 10. Anschlußdurchführungen 11 sind mit dem Aufsatzgehäuse 8 verbunden. Sie werden beim Aufsetzen des Aufsatzgehäuses auf das elektromagnetische Schaltgerät 1 mit den Spulenanschlüssen 3 des elektromagnetischen Schaltgerätes verbunden. An der Frontseite des Aufsatzgehäuses 8 sind diese Anschlußdurchführungen zugänglich, um - wie vorn geschildert - Bedämpfungsglieder für die Spule des elektromagnetischen Schaltgerätes anschliessen zu können. Zum Aufsetzen dieser Bedämpfungsglieder besitzt das Aufsatzgehäuse eine Ausnehmung 12, die durch eine Abdeckung 13 - siehe FIG 3 im Ausführungsbeispiel - abgedeckt ist. Das Aufsatzgehäuse 8 ist mit einer Anformung 14 ausgestattet, die einen der Spulenanschlüsse 3 im aufgesetzten Zustand abdeckt, so daß die Anschlußschraube mit dem Schraubendreher nicht mehr zugänglich ist. Im Aufsatzgehäuse 8 sind Nuten 15 bzw. 16 vorgesehen, in die Schaltungsplatinen 17 bzw. 18 einführbar sind. Die Schaltungsplatine 17 ist mit Bauelementen 19 bestückt. Die Schaltungsplatine 18 nimmt die Einstellelemente 20 auf, die durch die Frontseite des Ausatzgehäuses zumindest teilweise hindurchragen. Mit der Schaltungsplatine 17 sind zwei Lyrakontaktteile 21, 22 elektrisch und mechanisch verbunden. Der Lyrakontaktteil 21 umgreift beim Einschieben der Platine 17 die Anschlußdurchführung 11, wie in FIG 5 dargestellt. Der Lyrakontaktteil 22 kommt ebenfalls beim Einschieben mit einem Fortsatz 23, einer Zeitrelaisanschlußklemme 24 in Verbindung, die in dem Aufsatzgehäuse gehalten ist. Im aufgesetzten Zustand des Aufsatzgehäuses ist es lediglich erforderlich, Anschlußleitungen an die Zeitrelaisanschlußklemme 24 und an den einen Spulenanschluß 3 anzuschließen. Die Verbindung zwischen Zeitrelais und elektromagnetischem Schaltgerät erfolgt automatisch über die Anschlußdurchführungen. Im Aufsatzgehäuse 8 ist weiterhin ein Schieber 25 verschiebbar gelagert. Er ist über einen Ansatz 26 mit der Schaltstellungsanzeige des Schützes 1 kuppelbar. Eine Anformung 27 durchdringt die Frontseite des Aufsatzgehäuses 8, so daß die Stellung des Schaltgerätes an dieser Frontseite ersichtlich ist. Es ist auch ein mechanisches Einschalten des Schützes über die Anformung 27 möglich.The electromagnetic switching device or contactor 1 shown in FIGS. 1 to 3 corresponds to that shown in European Patent 0 189 924. It has on opposite sides the connections 2 for the contacts and for the coil connection 3 and in between the corresponding recesses for the towers 4 and 5, the dimensions of the towers of the auxiliary switch arrangement according to the European patent specification correspond. They are also equipped with a corresponding locking device 6, which can be released by the lever 7. The top housing 8 is divided into two parts transversely to the front side and consists of the housing halves 9 and 10. Connection bushings 11 are connected to the top housing 8. They are connected to the coil connections 3 of the electromagnetic switching device when the attachment housing is placed on the electromagnetic switching device 1. On the front of the top housing 8, these connection bushings are accessible in order - as described above - to be able to connect attenuators for the coil of the electromagnetic switching device. To attach these attenuators, the top housing has a recess 12, which is covered by a cover 13 - see FIG 3 in the embodiment. The top housing 8 is equipped with a molding 14 which covers one of the coil connections 3 in the attached state, so that the connecting screw is no longer accessible with the screwdriver. Grooves 15 and 16 are provided in the top housing 8, into which circuit boards 17 and 18 can be inserted. The circuit board 17 is equipped with components 19. The circuit board 18 accommodates the setting elements 20, which at least partially protrude through the front of the housing. With the circuit board 17, two Lyra contact parts 21, 22 are electrically and mechanically connected. When inserting the circuit board 17, the lyre contact part 21 engages around the leadthrough 11, as shown in FIG. The Lyrakontaktteil 22 also comes in connection with an extension 23, a timing relay terminal 24 in connection, which is held in the top housing. In the attached state of the top housing, it is only necessary to connect connecting lines to the timing relay connection terminal 24 and to the one coil connection 3. The connection between the time relay and the electromagnetic switching device is made automatically via the connection bushings. In the top housing 8, a slide 25 is also slidably mounted. It is connected to the switch position indicator of the contactor 1 via an extension 26 detachable. A molding 27 penetrates the front of the top housing 8, so that the position of the switching device on this front can be seen. It is also possible to switch the contactor on mechanically via the projection 27.
