Abstract

In the case of this terminal block, whose conductor connections (2) are connected via socket contacts (5) by means of a plug-on module (7) which contains a switching device, the desired interruption point (12) in the upper region of the plug-on module (7) is arranged to be freely visible from above and accessible, above the wiring plane of the terminal block. Easy handling of the interrupter lever (15) of the interruption point (12) is possible. In the event of damage in the region of the interruption point, it is sufficient to replace the plug-on module (7). <IMAGE>

Description

Die Erfindung betrifft eine Reihenklemme mit einem Klemmengehäuse aus Isolierstoff, mindestens einem darin angeordneten Leiteranschluß sowie darin angeordneten Anschlüssen und einem mit diesen kontaktierbaren, eine Schalteinrichtung beinhaltenden Aufsteckmodul sowie mit einer Trennstelle. Derartige Reihenklemmen mit Aufsteckmodul sind beispielsweise aus der DE 32 33 255 C2 bekannt. Dort ist zur Vermeidung der Gefahr von Fehlschaltungen an der Trennstelle das Klemmengehäuse so erweitert, daß die Trennstelle in diesem Gehäuse Platz findet. Die Trennstelle ist somit in der Klemme selbst integriert. Soweit dort eine Aneinanderreihung mehrerer Reihenklemmen vorgesehen ist, ist ferner einer größeren Anzahl derartiger aneinander angereihter Klemmen ein gemeinsamer Aufsteckmodul zugeordnet. Zwar ist bei dieser Ausgestaltung infolge der Integration der Trennstelle in der Klemme eine die Gefahr von Fehlschaltungen herabsetzende Zuordnung möglich, doch ist bei dieser Ausgestaltung die Trennstelle unten in der Klemme, bezogen auf die gesamte Schaltanlage, schlecht zugänglich, da die die Reihenklemmen tragenden Tragschienen in der Regel zwischen den Kabelkanälen, also mitten in der Leiterführung angeordnet sind. Neben der ungünstigen Zugänglichkeit ist auch damit eine schlechte Sicht auf den Trennhebel verbunden, was die Handhabung stört. Wenn darüber hinaus an der recht empfindlichen Trennstelle ein Schaden auftritt, muß bei dieser Anordnung die gesamte Klemme aus dem Klemmenverband herausgenommen und es muß ihre Verdrahtung gelöst werden. Bei der vorbekannten Ausführungsform ist auch keine Kodiermöglichkeit vorgesehen.The invention relates to a terminal block with a terminal housing made of insulating material, at least one conductor connection arranged therein as well as connections arranged therein and a plug-in module which can be contacted with them and contains a switching device, and with a separation point. Such terminal blocks with plug-on module are known for example from DE 32 33 255 C2. In order to avoid the risk of incorrect switching at the disconnection point, the terminal housing is expanded so that the disconnection point can be accommodated in this housing. The separation point is thus integrated in the terminal itself. Insofar as a series connection of several terminal blocks is provided, a common plug-on module is also assigned to a larger number of such clamped modules. Although in this embodiment, the integration of the isolating point in the terminal makes it possible to reduce the risk of incorrect switching, in this embodiment the isolating point at the bottom of the terminal is difficult to access, based on the entire switchgear, since the mounting rails carrying the terminal blocks in generally between the cable ducts, i.e. in the middle of the conductor routing. In addition to the unfavorable accessibility, this also has a poor view of the separating lever, which interferes with handling. If, moreover, at the quite sensitive separation point If damage occurs, the entire terminal must be removed from the terminal assembly with this arrangement and its wiring must be disconnected. In the known embodiment, no coding option is also provided.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Reihenklemme mit Aufsteckmodul der gattungsgemäßen Art zu schaffen, die eine wesentlich erleichterte Handhabung und gegebenenfalls Auswechselbarkeit der Trennstelle ermöglicht.The present invention has for its object to provide a terminal block with plug-on module of the generic type, which enables much easier handling and, if necessary, interchangeability of the separation point.

Die erfindungsgemäße Lösung besteht darin, daß die Trennstelle im oberen Bereich des Aufsteckmodules, oberhalb der Verdrahtungsebene der Reihenklemme, angeordnet ist.The solution according to the invention consists in that the separation point is arranged in the upper area of the plug-on module, above the wiring level of the terminal block.

Dank dieser Ausgestaltung ist der der Trennstelle zugeordnete Trennhebel sehr gut sichtbar und frei zugänglich. Im Falle der Beschädigung der Trennstelle kann die Reihenklemme in der Anordnung verbleiben. Es braucht auch ihre Verdrahtung nicht gelöst zu werden. Es genügt ein Auswechseln des Aufsteckmoduls, wobei danach infolge der angegebenen Lage innerhalb des Aufsteckmodules hier dann auch eine Reparatur oder ein Auswechseln der Trennstelle innerhalb des Aufsteckmodules problemlos möglich ist. In weiterer zweckmäßiger Ausgestaltung sind zur Aufnahme des Aufsteckmodules in der Kontaktebene der Klemme Buchsenkontakte vorgesehen, die Nuten haben, mit deren Hilfe eine die Fehlsteckung zwischen Aufsteckmodul und Reihenklamme verhindernde Kodierung mit Hilfe in die Nuten einzusteckender Kodierstücke problemlos möglich ist. In weiterer Ausgestaltung ist im Aufsteckmodul im oberen Bereich noch mindestens ein Prüfkontakt vorgesehen, der damit gut sichtbar und frei zugänglich liegt. Gemäß einer weiteren bevorzugten Ausgestaltung hat das Klemmengehäuse einseitig einen emporstehenden Führungssteg mit Führungen für die Hinleitung des Aufsteckmodules zu seinen Anschlüssen im Klemmengehäuse, so daß sich unter schonender Hinführung eine sichere Kontaktierung des Aufsteckmodules mit der Reihenklemme ergibt.Thanks to this configuration, the separation lever assigned to the separation point is very clearly visible and freely accessible. If the separation point is damaged, the terminal block can remain in the arrangement. There is also no need to disconnect their wiring. It is sufficient to replace the plug-on module, after which, as a result of the position specified within the plug-on module, repair or replacement of the separation point within the plug-on module is then possible without any problems. In a further expedient embodiment, socket contacts are provided for receiving the plug-on module in the contact level of the terminal, which have grooves, with the aid of which a coding which prevents the incorrect connection between the plug-on module and the terminal block is easily possible with the aid of coding pieces to be inserted into the grooves. In a further embodiment, at least one test contact is provided in the plug-in module in the upper area, which is therefore clearly visible and freely accessible. According to a further preferred embodiment the terminal housing has an upstanding guide bar on one side with guides for routing the plug-in module to its connections in the terminal housing, so that the plug-in module is safely contacted to the terminal block while being gently guided.

In einer Anreihung von Reihenklemmen hat in zweckmäßiger Ausgestaltung jede Klemme einen eigenen Steckmodul. Dies hat den Vorteil, daß innerhalb der Reihenklemmenanordnung die Reihenklemmen selbst völlig einheitlich ausgebildet sein können. Man benötigt nur eine Reihenklemmenausführung. Ob im entspresprechenden Stromkreis eine Trennstelle notwendig ist oder nicht, kann der Anwender bei der Endmontage selbst entscheiden, wenn man ihm Aufsteckmodule unterschiedlicher Ausführung einmal mit und einmal ohne Trennstelle zur Verfügung stellt.In a row of terminal blocks, each terminal has its own plug-in module in a practical embodiment. This has the advantage that the terminal blocks themselves can be designed completely uniform within the terminal block arrangement. You only need a terminal block version. During the final assembly, the user can decide whether or not a disconnection point is necessary in the corresponding circuit by providing plug-in modules of different designs with or without a separation point.

Die Reihenklemme hat ein Klemmengehäuse 1 aus Isolierstoff, in dem im dargestellten Ausführungsbeispiel zwei Leiteranschlüsse 2 für ankommende und abgehende elektrische Leiter vorgesehen sind. Auf der Eingangsseite ist der Leiteranschluß 2 über ein elektrisches Verbindungsstück 3 mit dem Kontakt 4 eines Buchsenkontaktes 5 verbunden, mit dem der Steckkontakt 6 eines eine Schalteinrichtung beinhaltenden Aufsteckmoduls 7 in Steckverbindung gebracht werden kann. Im elektrischen Kreis des Aufsteckmodules 7 ist ausgangsseitig ein weiterer Steckkontakt 6 vorgesehen, für den die Reihenklemme einen weiteren Buchsenkontakt 5 mit innenliegendem Kontakt 4 trägt, der seinerseits über ein elektrisches Verbindungsstück 8 mit dem ausgangsseitigen Leiteranschluß 2 verbunden ist.The terminal block has a terminal housing 1 made of insulating material, in which two conductor connections 2 are provided for incoming and outgoing electrical conductors in the exemplary embodiment shown. On the input side, the conductor connection 2 is connected via an electrical connector 3 to the contact 4 of a socket contact 5, with which the plug contact 6 of a plug-in module 7 containing a switching device can be connected. In the electrical circuit of the plug-on module 7, a further plug contact 6 is provided on the output side, for which the terminal block carries a further socket contact 5 with an internal contact 4, which in turn is connected to the output-side conductor connection 2 via an electrical connector 8.

Das Klemmengehäuse 1 hat ferner einseitig, im dargestellten Ausführungsbeispiel eingangsseitig, einen emporstehenden Führungssteg 9, an dem sich innenseitig Führungsstücke, beispielsweise Schwalbenschwanzführungsstücke 10, befinden, in denen über entsprechende Führungsstücke 11 das Gehäuse des Aufsteckmodules 7 in der Einsteckphase, d. h. bei der Hinführung der Steckkontakte 6 zu den Buchsenkontakten 5 in zuverlässiger Führung bewegen kann.The terminal housing 1 also has on one side, in the exemplary embodiment shown on the input side, an upstanding guide web 9, on the inside of which there are guide pieces, for example dovetail guide pieces 10, in which the housing of the plug-on module 7 is in the insertion phase, in other words via corresponding guide pieces 11. H. when moving the plug contacts 6 to the socket contacts 5 can move in reliable guidance.

Eine zugehörige Trennstelle 12 ist nun im oberen Bereich, vorzugsweise im oberen vorderseitigen bzw. eingangsseitigen Bereich des Aufsteckmodules 7 vorgesehen, so daß sich diese Trennstelle, wie insbesondere die Figur 3 zeigt, bei aufgestecktem Aufsteckmodul frei sichtbar und gut handhabbar deutlich oberhalb der unten liegenden Verdrahtungsebene der Reihenklemme befindet. im dargestellten Ausführungsbeispiel sind an der Trennstelle 12, wie insbesondere aus Figur 4 ersichtlich, Stromschienenstücke 13a und 13b vorgesehen, zwischen denen ein Trennkontakt 14 drehbar gelagert ist, und zwar über einen Trennhebel 15, der in diesem oberen vorderen Bereich aus dem Aufsteckmodul 7 tritt. Wie in Figur 4 illustriert, kann der Trennkontakt in eine die Stromschienenstücke 13a, 13b kontaktierende Lage sowie in eine die Kontaktierung unterbrechende Lage mittels des Trennhebels 15 gedreht werden. Die Anordnung des Trennhebels 15 zum Trennkontakt 14 ist so getroffen, daß in der Trennstellung der Trennhebel 15, wie in Figur 4 gestrichelt dargestellt, deutlich und gut sichtbar aus dem Aufsteckmodul 7 hervorsteht, während in der Kontaktlage der Trennhebel 15 eng an den Aufsteckmodul 7 angeschwenkt liegt. Versieht man dessen Gehäuse noch mit seitlichen schmalen Vorsprüngen 16, liegt der Trennhebel 15 in der Kontaktlage gegen unbeabsichtigte Betätigung geschützt zwischen diesen Vorsprüngen.An associated disconnection point 12 is now provided in the upper area, preferably in the upper front or input area of the plug-on module 7, so that this disconnect point, as shown in particular in FIG the terminal block. In the exemplary embodiment shown, busbar pieces 13a and 13b are provided at the disconnection point 12, as can be seen particularly in FIG. 4, between which a disconnection contact 14 is rotatably mounted, specifically via a disconnection lever 15 which emerges from the plug-on module 7 in this upper front region. As illustrated in FIG. 4, the isolating contact can be rotated into a position contacting the busbar pieces 13a, 13b and into a position interrupting the contacting by means of the isolating lever 15. The arrangement of the isolating lever 15 to the isolating contact 14 is such that, in the disconnected position, the isolating lever 15, as shown in dashed lines in FIG. 4, protrudes clearly and clearly from the plug-on module 7, while in the contact position, the isolating lever 15 swings close to the plug-on module 7 lies. If the housing is still provided with narrow lateral projections 16, the separating lever 15 is in the contact position, protected against unintentional actuation, between these projections.

Derartige Reihenklemmen mit Aufsteckmodul müssen im Regelfall Prüfmöglichkeiten, d. h. Prüfkontakte haben, in die Prüfstecker eingesteckt werden können. In diesem Sinn sind im dargestellten Ausführungsbeispiel oben im Aufsteckmodul 7 im Bereich der Trennstelle 12 durch entsprechende Steckbohrungen in den Stromschienenstücken 13a und 13b zwei Prüfkontakte 17 ausgebildet, in die Prüfstecker 18 gesteckt werden können. Der Aufsteckmodul hat damit eine Prüfebene, die sehr gut sichtbar und frei von oben, wieder weit oberhalb der Verdrahtungsebene der Klemme, zugänglich ist.Such terminal blocks with a plug-on module must generally have test facilities, ie test contacts, into which test plugs can be inserted. In this sense, two test contacts 17, into which test plugs 18 can be inserted, are formed in the exemplary embodiment shown above in the plug-in module 7 in the area of the separation point 12 by corresponding plug bores in the conductor rail pieces 13a and 13b. The plug-on module thus has a test level that is very clearly visible and freely accessible from above, again far above the wiring level of the terminal.

Auch der Reihenklemme selbst sind zweckmäßig sowohl eingangsseitig wie ausgangsseitig Prüfkontakte 19 und 20 zugeordnet, in die Prüfstecker 18 gesteckt werden können. In zweckmäßiger Ausgestaltung ist der Prüfkontakt 19 auf der Eingangsseite der Reihenklemme im oberen Ende des eingangsseitig vorgesehenen Führungssteges 9 angeordnet.Test terminals 19 and 20, into which test plugs 18 can be inserted, are also expediently assigned to the terminal block itself, both on the input side and on the output side. In an expedient embodiment, the test contact 19 is arranged on the input side of the terminal block in the upper end of the guide web 9 provided on the input side.

In weiterer zweckmäßiger Ausgestaltung weisen die Buchsenkontakte 5, in die der Aufsteckmodul 7 einsteckbar ist, Nuten 21 auf, in die Kodierstücke gesteckt werden können, so daß die zuverlässig zu treffende Verbindung einer Reihenklemme mit dem erforderlichen Aufsteckmodul über Kodierung gesichert werden kann.In a further expedient embodiment, the socket contacts 5, into which the plug-on module 7 can be inserted, have grooves 21 into which coding pieces can be inserted, so that the connection of a terminal block to the required plug-in module which is to be reliably made can be secured via coding.

Reihenklemmen der in Frage stehenden Art werden üblicherweise in Anreihung aneinander auf Tragschienen aufgerastet. Es ist nun ferner vorgesehen, daß in einer derartigen Anreihung von Reihenklemmen jede einzelne Klemme ihren eigenen Aufsteckmodul 7 hat, wie insbesondere aus Figur 2 ersichtlich. Es liegen dabei auch praktisch die Aufsteckmodule 7 in Anreihung aneinander. Da nicht in jedem Stromkreis einer derartigen Anreihung von Reihenklemmen eine Trennstelle notwendig ist, werden zweckmäßig zwei Modulausführungen vorgesehen, und zwar ein Aufsteckmodul 7 mit der Trennstelle 12 sowie auch ein Aufsteckmodul oder eine solche Trennstelle. Die Reihenklemmenausführung als solche kann immer die gleiche bleiben. Der Anwender kann bei der Endmontage entscheiden, ob er in der Anreihung der Reihenklemmen jeweils einen Aufsteckmodul mit Trennstelle oder einen solchen ohne Trennstelle einsetzt. Abweichend von der vorstehend beschriebenen Ausführungsform ist es auch möglich, mehreren Reihenklemmen der Anreihung einen gemeinsamen blockartigen Aufsteckmodul zuzuordnen. Das ermöglicht eine vereinfachte Bauweise und ergibt einen großen Innenraum für einen derartigen Aufsteckmodul, z. B. in Form eines standardisierten Relais.Terminal blocks of the type in question are usually snapped onto mounting rails in a row. It is now further provided that in such a series of terminal blocks, each individual terminal has its own plug-on module 7, as can be seen in particular from FIG. There are also practically the plug-in modules 7 in a row. Since a disconnection point is not necessary in each circuit of such a series of terminal blocks, two module designs are expediently provided, namely a plug-on module 7 with the disconnection point 12 and also a plug-on module or such a disconnection point. The terminal block version as such can always remain the same. During final assembly, the user can decide whether to use a plug-on module with a separating point or one without a separating point in the series connection of the terminal blocks. Deviating from the embodiment described above, it is also possible to assign a common block-type plug-in module to a plurality of terminal blocks in the series. This enables a simplified design and results in a large interior space for such a plug-on module, for. B. in the form of a standardized relay.
