Abstract
Description
Die vorliegende Erfindung betrifft ein Schütz, das wie folgt aufgebaut ist:
- Es weist ein Gehäuse auf, das eine Montageseite, eine Bedienseite, zwei Hauptanschlussflächen und zwei Seitenflächen aufweist.
- Die Bedienseite liegt der Montageseite gegenüber und ist mit der Montageseite über die Hauptanschlussflächen und die Seitenflächen verbunden, wobei die Hauptanschlussflächen einander gegenüber liegen und die Seitenflächen einander gegenüber liegen.
- Die Bedienseite weist einen erhabenen Mittelbereich und zwei beidseits des Mittelbereichs an den Mittelbereich angrenzende Randbereiche auf, wobei die Randbereiche an die Hauptanschlussflächen angrenzen und mit dem Mittelbereich über je eine Zusatzanschlussfläche verbunden sind.
- Hauptklemmen, die mit Lastkontakten des Schützes verbunden sind, weisen Hauptaufnahmeöffnungen auf, in die von je einer der Hauptanschlussflächen aus Hauptleitungen einführbar sind.
- Zusatzklemmen, über die Zusatzleitungen an das Schütz anschließbar sind, weisen Zusatzaufnahmeöffnungen auf, in die von je einer der Zusatzanschlussflächen aus die Zusatzleitungen einführbar sind.
- It has a housing which has a mounting side, an operating side, two main connection surfaces and two side surfaces.
- The operating side faces the mounting side and is connected to the mounting side via the main connection surfaces and the side surfaces, with the main connection surfaces facing each other and the side surfaces facing each other.
- The operating side has a raised center region and two edge regions adjoining the middle region on both sides of the middle region, wherein the edge regions adjoin the main connection surfaces and are connected to the middle region via an additional connection surface.
- Main terminals, which are connected to load contacts of the contactor, have main receiving openings, in each of which one of the main connection surfaces of main lines can be inserted.
- Additional terminals, via the additional cables can be connected to the contactor, have additional receiving openings, in each of which one of the additional connection surfaces from the additional lines can be inserted.
Die vorliegende Erfindung betrifft weiterhin einen Lastabzweig, bestehend aus einem Schütz der obenstehend beschriebenen Art und einem Zusatzgerät,
- wobei das Zusatzgerät mit dem Schütz an einer der Hauptanschlussflächen mechanisch und elektrisch verbunden ist,
- wobei mindestens eine Zusatzleitung in einer der dem Zusatzgerät zugewandten Zusatzklemmen geklemmt ist.
- wherein the attachment is mechanically and electrically connected to the contactor on one of the main connection pads,
- wherein at least one additional line is clamped in one of the auxiliary device facing additional terminals.
Derartige Schütze und derartige Lastabzweige sind allgemein bekannt. Oftmals sind bei dem Schütz Hauptbetätigungselemente, mittels derer die Hauptklemmen betätigbar sind, von den Randbereichen aus zugänglich. Weiterhin sind oftmals Zusatzbetätigungselemente, mittels derer die Zusatzklemmen betätigbar sind, vom Mittelbereich aus zugänglich.Such contactors and such load branches are well known. Often, in the contactor main actuators, by means of which the main terminals are actuated, accessible from the edge regions. Furthermore, additional operating elements by means of which the additional terminals can be actuated are often accessible from the central area.
In der Regel werden in den Zusatzklemmen beider Zusatzanschlussbereiche Leitungen geklemmt. Zumindest diejenigen Zusatzleitungen, die in einer dem Zusatzgerät zugewandten Zusatzklemme geklemmt sind, müssen daher entweder über den Mittelbereich und den vom Zusatzgerät abgewandten Randbereich geführt werden oder über das Zusatzgerät. Diese Vorgehensweise ist nachteilig, weil sie den Zugang zu dem Schütz oder dem Zusatzgerät und den Einblick auf das Schütz oder das Zusatzgerät beeinträchtigt. Ferner ist diese Ausgestaltung unästhetisch.As a rule, cables are clamped in the additional terminals of both additional connection areas. At least those additional lines, which are clamped in an additional terminal facing the accessory, must therefore be performed either over the central region and the side facing away from the attachment edge area or on the attachment. This approach is disadvantageous because it affects access to the contactor or the attachment and the view of the contactor or the attachment. Furthermore, this embodiment is unaesthetic.
Die Aufgabe der vorliegenden Erfindung besteht darin, eine Möglichkeit zu schaffen, die oben genannten Nachteile zu vermeiden.The object of the present invention is to provide a way to avoid the disadvantages mentioned above.
Die Aufgabe wird bei einem Schütz der eingangs genannten Art dadurch gelöst, dass in den Mittelbereich ein Leitungskanal eingebracht ist, der sich von dem einen der Randbereiche zum anderen der Randbereiche erstreckt.The object is achieved in a contactor of the type mentioned above in that in the central region a duct is introduced, which extends from one of the edge regions to the other of the edge regions.
Hiermit korrespondierend wird die Aufgabe für den obenstehend beschriebenen Lastabzweig dadurch gelöst, dass das Schütz wie zuletzt beschrieben ausgebildet ist und die mindestens eine Zusatzleitung durch den Leitungskanal geführt ist.Correspondingly, the object for the load branch described above is achieved in that the contactor is designed as described last and the at least one additional line is guided through the duct.
In der Regel verläuft der Leitungskanal parallel zu den Seitenflächen. Er kann hierbei, bezogen auf die Seitenflächen, mittig angeordnet sein. Vorzugsweise jedoch ist der Leitungskanal näher an der einen Seitenfläche angeordnet als an der anderen Seitenfläche.As a rule, the duct runs parallel to the side surfaces. It can be arranged centrally in relation to the side surfaces. Preferably, however, the duct is located closer to one side surface than to the other side surface.
Der Leitungskanal weist eine der einen Seitenfläche zugewandte Kanalwand und eine der anderen Seitenfläche zugewandte Kanalwand auf. Vorzugsweise ist sogar die der anderen Seitenfläche zugewandte Kanalwand näher an der einen Seitenfläche angeordnet als an der anderen Seitenfläche.The duct has one of the side wall facing a channel wall and the other side surface facing channel wall. Preferably, even the channel wall facing the other side surface is arranged closer to the one side surface than to the other side surface.
Das Schütz weist einen Stößel auf. In vielen Fällen ist der Stößel vom Mittelbereich aus zugänglich. Vorzugsweise ist bei dem erfindungsgemäßen Schütz der Stößel näher an der anderen Seitenfläche angeordnet als an der einen Seitenfläche.The contactor has a plunger. In many cases, the plunger is accessible from the central area. Preferably, in the contactor according to the invention, the plunger is arranged closer to the other side surface than on the one side surface.
Der Leitungskanal kann mittels einer Klappe abdeckbar sein. Hierbei ist es möglich, dass die Klappe den Leitungskanal und weitere Elemente - beispielsweise den gesamten Mittelbereich - abdeckt. Vorzugsweise jedoch ist mittels der Klappe ausschließlich der Leitungskanal abdeckbar.The duct can be covered by a flap. It is possible that the flap covers the duct and other elements - for example, the entire central area. Preferably, however, by means of the flap only the duct can be covered.
