Description

Die Erfindung betrifft ein Anschlussmodul für Niederspannungs-Leistungsschalter, nach dem Oberbegriff von Anspruch1.The invention relates to a connection module for low-voltage circuit breaker, according to the preamble of Anspruch1.

Von der Firma Moeller GmbH werden mehrpolige Leistungsschalter vom Typ NZM7 vertrieben, die sowohl auf der Einspeiseseite als auch auf der Abgangsseite ein Anschlussmodul mit gegeneinander isolierten Anschlussräumen aufweisen, die für unterschiedliche Anschlussarten zurüstbar sind. Vom Inneren der Leistungsschalters reichen mit einer Durchgangsbohrung versehene Anschlussschienen in die Anschlussräume. Um das Anschließen von Rundleitern zu ermöglichen, sind frontseitig in die Anschlussräume einsetzbare Rahmenklemmen vorgesehen, die mit dem Ansetzen des Anschlussmoduls an das Leistungsschaltergrundgehäuse um die Anschlussschienen greifen. Die Rahmenklemmen werden durch erste Führungselemente, die senkrecht zur Frontseite des Leistungsschalters verlaufen, und einer frontseitigen Abdeckhaube sowie den zur Bodenwand des Leistungsschalters gewandten Anschlussraumböden gehalten. Um das Anschließen von Flachleitern oder Kabelschuhen zu ermöglichen, sind entgegen der Anschlussseite in die Anschlussräume einsetzbare Schraubplatten vorgesehen. Die Schraubplatten werden klemmend durch zweite Führungselemente, die an den Anschlussraumböden parallel zur Bodenwand verlaufend ausgebildet sind, gehalten. Erste Anschlussschrauben reichen über Anschlussbohrungen der Flachleiter bzw. Kabelschuhe, die Durchgangsbohrungen der Anschlussschienen und Gewindebohrungen der Schraubplatten in Durchtrittsöffnungen, welche die Anschlussraumböden mit der Bodenwand verbinden. Um das Anschließen von Stromschienen eines bodenseitig mit dem Leistungsschalter zu verbindenden Sammelschienenadapters zu ermöglichen, sind Anschlusshülsen vorgesehen. Die zylindrischen Anschlusshülsen treten von der Bodenwand in die Durchtrittsöffnungen, stoßen einerseits an die Anschlussschienen und reichen anderseits aus der Bodenwand zu Anschlussbohrungen der Stromschienen. Zweite Anschlussschrauben greifen über die Durchgangsbohrungen der Anschlussschienen und durch die Anschlusshülsen in Muttergewinde der Stromschienen. Eine Abdeckhaube weist Zutrittsöffnungen auf, über welche die Klemmschrauben der Rahmenklemmen oder die ersten oder die zweiten Anschlussschrauben mittels eines Schraubwerkzeuges zu betätigen sind. Um die erforderlichen Luft- und Kriechstrecken zwischen den Anschlussräumen zu gewährleisten sind bei einem dreipoligen Leistungsschalter sechs bzw. bei einem vierpoligen Leistungsschalter acht einzelne Verschlussstopfen vorgesehen, die bei Anschluss über Rahmenklemmen oder über Schraubplatten in die Durchtrittöffnungen von der Bodenwand einzusetzen sind.Moeller GmbH distributes NZM7 multi-pole circuit breakers, which have a connection module on the infeed side as well as on the outgoing side with mutually insulated terminal compartments that can be equipped for different types of connection. From the inside of the circuit breaker with a through hole provided connecting rails rich in the terminal compartments. In order to enable the connection of round conductors, insertable frame terminals are provided on the front in the terminal compartments, which engage with the attachment of the connection module to the circuit breaker base housing to the connecting rails. The frame terminals are held by first guide elements that run perpendicular to the front of the circuit breaker, and a front cover and facing the bottom wall of the circuit breaker terminal compartment floors. In order to enable the connection of flat conductors or cable lugs, insertable screw plates are provided opposite the connection side in the terminal compartments. The screw plates are clamped by second guide elements which are formed to run parallel to the bottom wall of the terminal compartment floors held. The first connection screws extend over the connection holes of the flat conductors or cable lugs, the through holes in the connection rails and threaded holes in the screw plates in the openings, which connect the connection floor panels to the bottom wall. In order to enable the connection of busbars of a busbar adapter to be connected to the bottom of the circuit breaker, connecting sleeves are provided. The cylindrical connection sleeves pass from the bottom wall into the passage openings, abut on the one hand to the connection rails and on the other hand reach from the bottom wall to connection bores of the busbars. Second connecting screws reach over the through holes of the connecting rails and through the connecting sleeves in the female thread of the busbars. A cover hood has access openings, via which the clamping screws of the frame clamps or the first or the second terminal screws are to be actuated by means of a screwing tool. In order to ensure the required clearance and creepage distances between the terminal compartments are provided in a three-pole circuit breaker six or a four-pole circuit breaker eight individual plugs, which are to be inserted in the passage openings of the bottom wall when connected via box terminals or screw plates.

Der Erfindung liegt die Aufgabe zugrunde, die erforderlichen Luft- und Kriechstrecken ohne besondere Einzelteile in der Art bodenseitig einzusetzender Verschlussstopfen zu gewährleisten.The invention has for its object to ensure the required clearance and creepage distances without special items in the type bottom-side inserted stopper.

Ausgehend von einem Anschlussmodul der eingangs genannten Art wird die Aufgabe erfindungsgemäß durch die Merkmale des Anspruches 1 gelöst, während den Unteransprüchen vorteilhafte Weiterbildungen zu entnehmen sind..Starting from a connection module of the type mentioned, the object is achieved by the features of claim 1, while the subclaims advantageous developments are shown ..

Das erfindungsgemäße Anschlussmodul ist in an sich bekannter Weise für das Anschließen von Rundkabeln mittels Rahmenklemmen, von Flachleitern oder Kabelschuhen mittels Schraubplatten und von Stromschienen eines Sammelschienenadapters mittels Anschlusshülsen geeignet. Bei der Verwendung von Schraubplatten werden die Schraubenenden der ersten Anschlussschrauben von den zylindrischen Aufnahmen aufgenommen. Bei den mittels der Rahmenklemmen und der Schraubplatten vorzunehmenden Anschlussarten bleiben die Aufnahmen durch die ausbrechbaren Wandteile verschlossen. Zur Realisierung der mittels der Anschlusshülsen vorzunehmenden Anschlussart, sind in einfacher Weise - beispielsweise mittels eines Schraubendrehers - die ausbrechbaren Wandteile zu entfernen, um danach die Anschlusshülsen durch die Aufnahmen zu führen. Zur Gewährleistung der erforderlichen Luft- und Kriechstrecken zwischen den Anschlussräumen sind keine zusätzlichen Vorkehrungen in Form von verschließenden Zusatzteilen erforderlich.The connection module according to the invention is suitable in a conventional manner for the connection of round cables by means of frame terminals, flat conductors or cable lugs by means of screw plates and busbars of a busbar adapter by means of connecting sleeves. When using screw plates, the screw ends of the first connection screws are received by the cylindrical receptacles. In the connection types to be carried out by means of the frame clamps and the screw plates, the receptacles remain closed by the break-out wall parts. In order to realize the type of connection to be made by means of the connecting sleeves, the break-off wall parts are to be removed in a simple manner-for example by means of a screwdriver-in order subsequently to guide the connecting sleeves through the receptacles. To ensure the required clearances and creepage distances between the connection spaces, no additional measures in the form of closing additional parts are required.

Die Anschlusshülsen können je nach Ausgestaltung von der Bodenseite oder von der Frontseite durch die Aufnahmen geführt werden. Einerseits ist es von Vorteil, die zur Frontseite weisende Stirnseite der Anschlusshülsen zur Verminderung des elektrischen Übergangswiderstandes zu den Anschlussschienen kragenförmig aufzuweiten. Anderseits ist es von Vorteil, die zu den Stromschienen reichende Stirnseite der Anschlusshülsen zur Bildung eines stabilen Positionierung gegenüber der Bodenwand kragenförmig aufzuweiten. Bei mehrkantig-zylindrischer Ausbildung der Aufnahmen können statt Schraubplatten als Normteile erhältliche Sperrzahnmuttern verwendet werden, die vor Anbringen des Anschlussmoduls an das Grundgehäuse in die Aufnahmen einzulegen sind.Depending on the design, the connection sleeves can be guided from the bottom side or from the front side through the receptacles. On the one hand, it is advantageous to widen the front side of the connecting sleeves facing the front in order to reduce the electrical contact resistance to the connecting rails like a collar. On the other hand, it is advantageous to widen the end face of the connecting sleeves extending to the busbars in a collar-like manner in order to form a stable positioning relative to the bottom wall. In polygonal-cylindrical design of recordings can be used instead of screw as standard parts available ratchet nuts, which are to be inserted before attaching the connection module to the basic housing in the recordings.

Nach Fig. 1 weist das boden- und anschlussseitig dargestellte, aus einem Kunststoff geformte dreipolige Anschlussmodul 2 eine im wesentliche quaderförmige Form auf. In dem Anschlussmodul 2 sind drei Anschlussräume 4 ausgebildet, die seitlich von Trennwänden 6 begrenzt werden. Das Anschlussmodul weist weiterhin eine geräteseitige hintere Wand 8 sowie eine Bodenwand 10 auf. In Verlängerung eines jeden Anschlussraumes 4 ist die Bodenwand mit einem ausbrechbaren Wandteil 11 versehen. Wie nach Fig. 2 bis Fig. 4 für nur eine Anschlussseite dargestellt, wird an beide Anschlussseiten eines nur fragmentarisch dargestellten Grundgehäuses 12 eines nicht weiter dargestellten dreipoligen Leistungsschalters je ein Anschlussmodul 2 über Feder-Nut-Verbindungen 14 befestigt. Aus dem Inneren des Grundgehäuse 12 ragt jeweils eine Anschlussschiene 16 in jeden Anschlussraum 4. Die Anschlussschienen 16 sind endseitig gefaltet und weisen eine Durchgangsbohrung 18 auf. Zur fronseitigen und teilweise anschlussseitigen Begrenzung der Anschlussräume 4 wird eine Abdeckhaube 20 auf das Anschlussmodul 2 aufgesetzt und mittels Schrauben befestigtTo Fig. 1 has the ground and connection side shown, molded from a plastic three-pin connection module 2 in a substantially cuboid shape. In the connection module 2 three connection spaces 4 are formed, which are bounded laterally by partitions 6. The connection module furthermore has a device-side rear wall 8 and a bottom wall 10. In extension of each terminal space 4, the bottom wall is provided with a breakable wall portion 11. As after Fig. 2 to Fig. 4 shown for only one connection side, a connection module 2 is attached via spring-groove connections 14 to both connection sides of a fragmentary illustrated housing 12 of a three-pole circuit breaker, not shown. From the interior of the base housing 12 in each case a connecting rail 16 projects into each terminal space 4. The connecting rails 16 are folded at the ends and have a through hole 18. For fronseitigen and partially connection-side boundary of the connection spaces 4, a cover 20 is placed on the connection module 2 and secured by screws

Nach Fig. 2 ist das Anschlussmodul 2 zum Anschließen von Rundleitern 21 ausgestattet. Dazu sind vor Aufsetzen der Abdeckhaube 20 auf das Anschlussmodul 2 und vor Anbringen des Anschlussmoduls 2 an das Grundgehäuse 12 frontseitig Rahmenklemmen 22 in die Anschlussräume 4 einsetzt worden. Jede Rahmenklemme 22 besteht in üblicher Weise aus einem Klemmrahmen 24, aus einer in diesem über eine Gewindeführung 23 geführte Klemmschraube 26 und aus einer an deren Ende drehbar befestigten Klemmplatte 28. Die Rahmenklemmen 22 werden durch leistenförmige seitliche Führungselemente 30 (Fig. 1), die in den Trennwänden 6 senkrecht zur Frontseite 32 des Grundgehäuses 12 verlaufen, der Abdeckhaube 20 und den Anschlussraumböden 34 gehalten. Nach dem Aufclipsen des Anschlussmoduls 2 an das Grundgehäuse 12 greifen die Klemmrahmen 24 um die Anschlussschienen 16. Die Klemmschrauben sind frontseitig über in der Abdeckhaube 20 eingelassene Schraubzugangsöffnungen 36 zu betätigen. Die ausbrechbaren Wandteile 11 werden für die gezeigte Zurüstung des Anschlussmoduls 2 mit Rahmenklemmen 22 beibehalten.To Fig. 2 the connection module 2 is equipped for connecting round conductors 21. For this purpose, before mounting the cover 20 on the connection module 2 and before attaching the connection module 2 to the base housing 12 front frame clamps 22 have been used in the connection spaces 4. Each frame clamp 22 consists in the usual way of a clamping frame 24, a guided in this via a threaded guide 23 clamping screw 26 and from a rotatably mounted at the end of the clamping plate 28. The frame clamps 22 are formed by strip-shaped lateral guide elements 30 (FIGS. Fig. 1 ), which extend in the partitions 6 perpendicular to the front side 32 of the base housing 12, the cover 20 and the terminal compartment bottoms 34 are held. After clipping the connection module 2 to the base housing 12, the clamping frames 24 engage around the connecting rails 16. The clamping screws are to be actuated on the front side via screw access openings 36 embedded in the covering hood 20. The break-out wall parts 11 are retained for the shown equipment of the connection module 2 with frame clamps 22.

Nach Fig. 3 ist das Anschlussmodul 2 zum Anschließen von Flachleitern oder Kabelschuhen 38 ausgestattet. Dazu sind vor dem Anbringen des Anschlussmoduls 2 am Grundgehäuse 12 von der hinteren Wand 8 zwischen Anschlussschienen 16 und Anschlussraumböden 34 einsetzbare Schraubplatten 40 vorgesehen. Die Schraubplatten 40 werden durch schwalbenschwanzförmige, bodenseitige Führungselemente 42 (Fig. 5), die an den Anschlussraumböden 34 parallel zur Bodenwand 10 verlaufend ausgebildet sind, klemmend gehalten. Erste Anschlussschrauben 44 reichen über Anschlussbohrungen 46 der Flachleiter bzw. Kabelschuhe 38, die Durchgangsbohrungen 18 der Anschlussschienen 16 und Gewindebohrungen 48 der Schraubplatten 40 in Aufnahmen 50. Die achtkantig zylindrisch ausgebildeten Aufnahmen 50 gehen von den Anschlussraumböden 34 aus, verlaufen konzentrisch zu den Durchgangsbohrungen 18 der Anschlussschienen 16 und sind bodenseitig durch die ausbrechbaren Wandteile 11 verschlossen. Die ersten Anschlussschrauben 44 sind frontseitig über die Schraubzugangsöffnungen 36 in der Abdeckhaube 20 zu betätigen.To Fig. 3 the connection module 2 is equipped for connecting flat conductors or cable lugs 38. For this purpose, 34 insertable screw plates 40 are provided before attaching the connection module 2 on the base housing 12 of the rear wall 8 between connecting rails 16 and terminal compartment floors. The screw plates 40 are dovetail-shaped, bottom guide elements 42 (FIG. Fig. 5 ), which are formed running parallel to the bottom wall 10 at the terminal compartment floors 34, clamped. First terminal screws 44 extend over connecting holes 46 of the flat conductor or cable lugs 38, the through holes 18 of the connecting rails 16 and threaded holes 48 of the screw 40 in receptacles 50. The octagonal cylindrically shaped receptacles 50 start from the terminal compartment floors 34, extend concentrically to the through holes 18 of Connecting rails 16 and the bottom side are closed by the break-out wall parts 11. The first connection screws 44 are to be actuated on the front side via the screw access openings 36 in the cover hood 20.

Nach Fig. 4 ist das Anschlussmodul 2 zum Anschließen von Stromschienen 52 eines bodenseitig mit dem Leistungsschalter zu verbindenden, nicht weiter dargestellten Sammelschienenadapters ausgestattet. Hierzu sind zylindrische Anschlusshülsen 54 vorgesehen. Nachdem die ausbrechbaren Wandteile 11 (Fig. 1) herausgebrochen worden sind, werden die Anschlusshülsen 54 von der Bodenwand 10 durch die Aufnahmen 50 geführt. Die fronseitige Stirnseite 56 der Anschlusshülsen 54 haben über je eine Zwischenscheibe 58 elektrischen Kontakt mit den Anschlussschienen 16. Die bodenseitige Stirnseite der Anschlusshülsen 54 ist zu einem Kragen 60 aufgeweitet und liegt mit dem Kragen 60 bündig von außen an der Bodenwand 10 an. Zweite Anschlussschrauben 62 greifen über die Durchgangsbohrungen 18 der Anschlussschienen 16, durch die Zwischenscheiben 58 und durch die Anschlusshülsen 54 in ein Muttergewinde 64 der Stromschienen 52 . Auch die zweiten Anschlussschrauben 62 sind frontseitig über die Schraubzugangsöffnungen 36 zu betätigen. Alternativ zu den vorstehend beschriebenen Anschlusshülsen 54, können die Anschlusshülsen auch so gestaltet sein, dass sie auch oder nur allein mit einem frontseitigen, zur Anschlussschiene 16 gerichteten Kragen versehen sind.To Fig. 4 is the connection module 2 for connecting busbars 52 of a bottom side to be connected to the circuit breaker, not shown busbar adapter equipped. For this purpose, cylindrical connecting sleeves 54 are provided. After the break-off wall parts 11 ( Fig. 1 ) have been broken, the ferrules 54 are guided by the bottom wall 10 through the receptacles 50. The fronseitige end face 56 of the connecting sleeves 54 have via an intermediate disc 58 electrical contact with the connecting rails 16. The bottom end face of the connecting sleeves 54 is flared to a collar 60 and is flush with the collar 60 from the outside to the bottom wall 10. Second connecting screws 62 engage over the through-holes 18 of the connecting rails 16, through the intermediate disks 58 and through the connecting sleeves 54 into a female thread 64 of the busbars 52.
