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.
The present invention relates to a contactor constructed as follows:
  • 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 each.
  • 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.
The present invention further relates to a load branch consisting of a contactor of the type described above and an auxiliary device,
  • 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 region 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.

Weiter ist aus dem Dokument WO 01/39232 A ein Niederspannungs-Leistungsschalter mit einem eine Vorder- und eine Rückwand aufweisenden Gehäuse bekannt, dessen Vorderwand der Rückwand gegenüberliegt und als eine Bedienseite ausgebildet ist. Das Gehäuse umfasst weiter zwei Seiten- sowie eine Boden- und eine Deckfläche, die die Vorder- mit der Rückwand verbinden. Die Seitenflächen liegen einerseits einander gegenüber und die Boden- und die Deckfläche liegen andererseits einander gegenüber. Am Boden der Gehäuserückwand ist ein Kabelkanal integriert, der sich im wesentlichen über die gesamte Breite des Niederspannungs-Leistungsschalters erstreckt und in Richtung zur Gehäusevorderwand eine oder mehrere Durchtrittsöffnungen zum Hindurchführen von Verbindungsleitungen zwischen Stromwandlern und einer frontseitigen elektronischen Auslöseeinheit aufweist.Next is from the document WO 01/39232 A a low-voltage circuit breaker having a front and a rear wall having housing, the front wall of the rear wall opposite and is formed as an operating side. The housing further comprises two side and a bottom and a top surface, which connect the front and the rear wall. The side surfaces are on the one hand opposite each other and the bottom and the top surface are on the other hand opposite each other. At the bottom of the housing back a cable channel is integrated, which extends substantially over the entire width of the low-voltage circuit breaker and in the direction of the housing front wall has one or more passages for passing connecting lines between current transformers and a front electronic trip unit.

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 the 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.

Schematisch dargestellte Hauptklemmen 13, 13', die mit Lastkontakten 14 des Schützes 1 verbunden sind, weisen Hauptaufnahmeöffnungen 15, 15' auf. In die Hauptaufnahmeöffnungen 15, 15' sind Hauptleitungen 16, 16' einführbar. Die Einführbarkeit ist hierbei von je einer der Hauptanschlussflächen 8, 8' aus gegeben.Schematically illustrated main terminals 13, 13 ', which are connected to load contacts 14 of the contactor 1, have main receiving openings 15, 15'. In the main receiving openings 15, 15 'are main lines 16, 16' insertable. The insertability is in this case given by one of the main connection surfaces 8, 8 '.

Das Schütz 1 weist weiterhin schematisch angedeutete Zusatzklemmen 17, 17' auf. Über die Zusatzklemmen 17, 17' sind Zusatzleitungen 18, 18' an das Schütz 1 anschließbar.

Die Zusatzklemmen 17, 17' weisen Zusatzaufnahmeöffnungen 19, 19' auf, in welche die Zusatzleitungen 18, 18' einführbar sind. Die Zusatzleitungen 18, 18' sind hierbei von je einer der Zusatzanschlussflächen 12, 12' aus in die Zusatzaufnahmeöffnungen 19, 19' einführbar.The contactor 1 further comprises schematically indicated additional terminals 17, 17 '. About the additional terminals 17, 17 'additional lines 18, 18' to the contactor 1 can be connected. The additional lines 18, 18 'are used, for example, the tapping of auxiliary signals, supplying a power supply and optionally the separate supply of a control signal for the contactor 1. The additional terminals 17, 17' have additional receiving openings 19, 19 ', in which the additional lines 18, 18th 'are insertable. The additional lines 18, 18 'are in this case of one of the additional connection surfaces 12, 12' from in the additional receiving openings 19, 19 'insertable.

In vielen Fällen sind die Hauptklemmen 13, 13' als Schraubklemmen ausgebildet. Insbesondere in diesem Fall sind Hauptbetätigungselemente 20, 20' (nämlich Schrauben), mittels derer die Hauptklemmen 13, 13' betätigbar sind, von den Randbereichen 11, 11' aus zugänglich.In many cases, the main terminals 13, 13 'are designed as screw terminals.

Der Leitungskanal 23 weist zwei Kanalwände 25, 25' auf. Die eine Kanalwand 25 ist der einen Seitenfläche 9 zugewandt, die andere Kanalwand 25' der anderen Seitenfläche 9'. Die der anderen Seitenfläche 9' zugewandte Kanalwand 25' ist näher an der einen Seitenfläche 9 angeordnet als an der anderen Seitenfläche 9'. Der Leitungskanal 23 ist in der Ausgestaltung der FIG 2 und 3 somit vollständig näher an der einen Seitenfläche 9 angeordnet als an der anderen Seitenfläche 9'.The duct 23 has two channel walls 25, 25 '. The one channel wall 25 faces the one side surface 9, the other channel wall 25 'of the other side surface 9'. The other side surface 9 'facing channel wall 25' is arranged closer to the one side surface 9 than on the other side surface 9 '. The duct 23 is in the embodiment of FIGS. 2 and 3 thus completely closer to the one side surface 9 arranged as on the other side surface 9 '.

Der Leitungskanal 23 ist vorzugsweise mittels einer Klappe 26 abdeckbar. Hierbei ist vorzugsweise mittels der Klappe 26 ausschließlich der Leitungskanal 23 abdeckbar.

In this case, preferably only by means of the flap 26, the conduit 23 can be covered. It would be, however alternatively possible to cover also other elements - in particular the entire central region 10 - with the flap 26.

Das Schütz 1 weist einen Stößel 27 auf. Der Stößel 27 ist gemäß FIG 3 vom Mittelbereich 10 aus zugänglich. Der Stößel 27 ist hierbei näher an der anderen Seitenfläche 9' angeordnet als an der einen Seitenfläche 9. Er ist also ebenfalls außermittig angeordnet. Mittels des Stößels 27 kann ein Hilfsgerät betätigt werden, das bedienseitig an das Schütz 1 ansetzbar ist.The contactor 1 has a plunger 27. The plunger 27 is according to FIG. 3 accessible from the central area 10. The plunger 27 is in this case arranged closer to the other side surface 9 'than on the one side surface 9. It is thus also arranged off-center. By means of the plunger 27, an auxiliary device can be actuated, the operator side of the contactor 1 can be attached.

Die Ausgestaltung gemäß den FIG 4 bis 6 entspricht im Wesentlichen der Ausgestaltung der FIG 1 bis 3. Die einzigen Unterschiede bestehen darin,

  • dass das Zusatzgerät 2 nicht als Leistungsschalter, sondern als Überlastrelais ausgebildet ist und
  • dass das Zusatzgerät 2 dem Schütz 1 nicht vorgeschaltet, sondern nachgeschaltet ist.
The embodiment according to the FIGS. 4 to 6 corresponds essentially to the embodiment of 1 to 3 , The only differences are
  • that the attachment 2 is not designed as a circuit breaker, but as an overload relay and
  • that the attachment 2 is not upstream of the contactor 1, but downstream.

Die beiden Unterschiede der Ausgestaltung der FIG 4 bis 6 im Verhältnis zur Ausgestaltung der FIG 1 bis 3 sind prinzipiell unabhängig voneinander realisierbar. In der Regel werden sie jedoch kombiniert realisiert.The two differences in the design of the FIGS. 4 to 6 in relation to the design of the 1 to 3 are in principle independently feasible. As a rule, however, they are realized in combination.

Die obige Beschreibung dient ausschließlich der Erläuterung der vorliegenden Erfindung. Der Schutzumfang der vorliegenden Erfindung soll hingegen ausschließlich durch die beigefügten Ansprüche bestimmt sein.The above description is only for explanation of the present invention. The scope of the present invention, however, is intended to be determined solely by the appended claims.
