Die DE 698 00453 T2 (EP 896 387 B1 ) zeigt ein mehrpoliges elektrisches Schaltgerät mit einem nicht weiter ausgeführten Schaltgerätegehäuse, aus dessen Anschlussseite Anschlussschienen ragen. Über die Anschlussschienen sind Rahmenklemmen zu schieben, die von einem kastenartigen Klemmengehäuse aufgenommen werden. Das Klemmengehäuse ist am Schaltgerätegehäuse befestigbar und anschlussseitig von einem abnehmbaren und mit Kabeleintrittöffnungen ausgestatteten Deckel verschließbar.DE 698 00453 T2 (EP 896 387 B1) shows a multi-pole electrical switchgear with a switchgear housing, which is not further elaborated, from whose connection side connection rails protrude. Box terminals are to be pushed over the connecting rails and are received in a box-like terminal housing. The terminal housing can be attached to the switchgear housing and can be closed on the connection side by a removable cover equipped with cable entry openings.
Zur anschlusstechnischen Komplettierung der bekannten Schaltschütze sind jeweils zwei Klemmengehäuse und ein am Gehäuseoberteil zu befestigender Gehäusedeckel zu montieren. Daraus leitet sich als Aufgabe der Erfindung die Vereinfachung der anschlusstechnischen Komplettierung ab.To complete the connection of the known contactors, two terminal housings and a housing cover to be attached to the upper housing part must be installed. From this, the task of the invention is derived to simplify the completion of the connection technology.
Ausgehend von einem Schaltschütz der eingangs genannten Art wird die Aufgabe er- findungsgemäß durch die Merkmale des unabhängigen Anspruches gelöst, während den abhängigen Ansprüchen vorteilhafte Weiterbildungen der Erfindung zu entnehmen sind.Starting from a contactor of the type mentioned in the introduction, the object is achieved according to the invention by the features of the independent claim, while advantageous developments of the invention can be found in the dependent claims.
Die erfindungsgemäße Integration der Klemmengehäuse in einem zweiteiligen Ge- h usedeckel führt zu einer Verminderung der zur anschlusstechnischen Komplettierung notwendigen Gehäuseteile um ein Drittel. Die mit den Rahmenklemmen bestückten Deckelhälften sind in einfacher Weise auf dem Gehäuseoberteil zu befestigen. Es ist für das Zusammenfügen von Deckelhälften und Gehäuseoberteil von Vorteil, wenn an den Seitenwänden und an den Klemmengehäusen miteinander in Wirkverbindung, insbesondere in Klemmverbindung, tretende Führungs- und Gegenfüh- rungsmittel, insbesondere zur Frontseite parallel verlaufende Führungsleisten an den Seitenwänden und Führungsnuten an den Deckelhälften, vorgesehen sind.The inventive integration of the terminal housings in a two-part housing cover leads to a reduction in the housing parts required for the connection-related completion by a third. The cover halves equipped with the box clamps can be easily attached to the upper part of the housing. It is advantageous for the joining of the cover halves and the upper housing part if guide and countermeasures which act in operative connection with one another, in particular in a clamp connection, on the side walls and on the terminal housings, in particular guide strips on the side walls and guide grooves on the cover halves which run parallel to the front , are provided.
Eine vorteilhafte Weiterbildung der Erfindung besteht darin, dass die Seitenwände des Gehäuseoberteils die als Klemmengehäuse ausgebildeten anschlussseitigen De- ckelschenkel seitlich umgreifen und mit diesen eine Rastverbindung eingehen. Hierbei ist es wiederum vorteilhaft, wenn in den Seitenwänden die mit den an den anschlussseitigen Deckelschenkeln vorgesehenen Rastmitteln zusammenwirkenden Gegenrastmittel ausgebildet sind.An advantageous further development of the invention consists in that the side walls of the upper housing part laterally grip around the connection-side cover legs, which are designed as terminal housings, and engage with them in a snap-in connection. Here, it is again advantageous if the counter-locking means cooperating with the locking means provided on the connection-side cover legs are formed in the side walls.

In Fig. 1 und Fig. 2 sind von dem Schaltgerätegehäuse des erfindungsgemäßen dreipoligen Schaltschützes ein Gehäuseoberteil 2 und zwei Deckelhälften 4 und 6 darge- stellt. Das Gehäuseoberteil 2 wird auf ein Gehäuseunterteil aufgesetzt, ist jedoch als für die Erfindung unwesentlich nicht dargestellt und nimmt den Magnetantrieb des Schaltschützes auf. Im Oberteil 2 sind Anschlussschienen 8 befestigt, die auf jeder Anschlussseite 10 bzw. 12 nach außen ragen. Im Inneren des Gehäuseoberteils 2 enden die Anschlussschienen 8 mit feststehenden Kontakten, die polweise über ebenfalls nicht dargestellte Kontaktbrücken, die von dem Magnetantrieb betätigt werden, verbunden bzw. getrennt werden.1 and 2 show an upper housing part 2 and two cover halves 4 and 6 of the switching device housing of the three-pole contactor according to the invention. The upper housing part 2 is placed on a lower housing part, but is not shown as not essential to the invention and takes up the magnetic drive of the contactor. In the upper part 2, connecting rails 8 are fastened, which project outwards on each connection side 10 or 12. Inside the upper housing part 2 The connecting rails 8 end with fixed contacts which are connected or disconnected in poles via contact bridges, also not shown, which are actuated by the magnetic drive.
Die Deckelhälften 4 und 6 sind als sich gegenüberstehende räumliche Rechteckwinkel ausgebildet. Die Deckelhalften 4 und 6 bestehen jeweils aus einem mit der Frontseite 14 des Schaltschützes abschließenden frontseitigen Deckelschenkel 16 und aus einem mit der jeweilige Anschlussseite 10 bzw. 12 abschließenden anschlussseitigen Deckelschenkel 18.The cover halves 4 and 6 are designed as opposing spatial rectangular angles. The cover halves 4 and 6 each consist of a front cover leg 16, which closes with the front side 14 of the contactor, and a cover leg 18, which ends with the respective connection side 10 and 12, respectively.
Weiterhin sind für jede Anschlussseite 10 und 12 drei Rahmenklemmen 20 vorgesehen. Die metallischen Rahmenklemmen 20 bestehen in üblicherweise aus einem Klemmrahmen 22, einem Klemmbügel 24 und einer Klemmschraube 26. Nach Fig. 3 und Fig. 5 weisen die kastenartig ausgebildeten anschlussseitigen Deckelschenkel 18 quaderförmige Aufnahmeräume 28 auf, in welche die Rahmenklemmen 20 entgegengesetzt zur Frontseite 14 eingeführt werden. Die anschlussseitigen Deckelschenkel 18 dienen damit als Klemmengehäuse. An den Innenwänden der Aufnahmeräume 28 sind gemäß Fig. 5 gegenüberliegend spitznasige Noppen 30 ausgebildet, zwischen denen die Rahmenklemmen 20 über ihren Klemmrahmen 22 klemmend gehalten werden.Furthermore, three box terminals 20 are provided for each connection side 10 and 12. The metallic frame clamps 20 usually consist of a clamping frame 22, a clamping bracket 24 and a clamping screw 26. According to FIGS. 3 and 5, the box-shaped connection-side cover legs 18 have cuboid-shaped receiving spaces 28, into which the frame clamps 20 are inserted opposite to the front side 14 become. The connection-side cover legs 18 thus serve as a terminal housing. According to FIG. 5, pointed-nosed knobs 30 are formed on the inner walls of the receiving spaces 28, between which the frame clamps 20 are held by their clamping frame 22.
Die mit den Rahmenklemmen 20 bestückten Deckelhälften 4 und 8 werden mit einer seitlichen Bewegung in Richtung zu den Anschlussschienen 8 auf das Gehäuseoberteil 2 geschoben. Dabei umfangen die Klemmrahmen 22 die Anschlussschienen 8. An den Innenseiten der gegenüberstehenden Seitenwänden 32 des Gehäuseoberteils 2 sind parallel zur Frontseite 14 verlaufende Führungsmittel 34 in Form von Führungsleisten ausgebildet. An den seitlichen Außenflächen der frontseitigen Deckelschenkel 16 sind parallel zur Frontseite 14 verlaufende Gegenführungsmittel 36 in Form von Führungsnuten ausgebildet. Beim Aufschieben der Deckelhälften 4 und 6 greifen die Führungsmittel 34 in die Gegenführungsmittel 36. An den anschlussseitigen Deckelschenkeln 18 sind auf jeder seitlichen Außenfläche zwei Rastmittel 38 in Form von Rastnoppen ausgebildet, die beim Aufschieben der Deckelhälften 4 und 6 in jeweils zwei Gegenrastmittel 40 in Form von an den Seitenwänden 32 ausgebilde- ten Rastöffnungen einrasten und damit die Deckelhälften 4 und 6 stabil am Geh useoberteil 2 halten.The cover halves 4 and 8 equipped with the frame clamps 20 are pushed onto the upper housing part 2 with a lateral movement in the direction of the connecting rails 8. In this case, the clamping frames 22 enclose the connecting rails 8. On the inner sides of the opposite side walls 32 of the upper housing part 2, guide means 34 in the form of guide strips are formed which run parallel to the front side 14. On the lateral outer surfaces of the front-side cover legs 16, counter-guiding means 36 running parallel to the front side 14 are formed in the form of guide grooves. When the cover halves 4 and 6 are slid on, the guide means 34 engage in the counter-guide means 36. Two latching means 38 in the form of latching knobs are formed on the connection-side lid legs 18 on each lateral outer surface, each of which forms two counter-latching means 40 when the lid halves 4 and 6 are slid on of trained on the side walls 32 Engage the ten locking openings and thus hold the cover halves 4 and 6 stably on the upper housing part 2.
Im fertig montierten Zustand des Schaltschützes werden die Enden anzuschließender Leiter über Zuführöffnungen 42, die in den anschlussseitigen Deckelschenkeln 18 ausgespart sind, in die Rahmenklemmen 20 eingeführt. Durch Andrehen der Klemmschrauben 26 mittels eines Schraubwerkzeuges, das über in den frontseitigen Deckelschenkeln 18 vorgesehene Zutrittsöffnungen 44 eingeführt wird, werden die Leiterenden anschließend festgeklemmt. In the fully assembled state of the contactor, the ends of the conductors to be connected are inserted into the frame terminals 20 via feed openings 42 which are recessed in the connection-side cover legs 18. By tightening the clamping screws 26 by means of a screwing tool, which is inserted through access openings 44 provided in the front cover legs 18, the conductor ends are then clamped.
