Zum Anschließen und/oder Verbinden von nicht dargestellten elektrischen Leitern, beispielsweise elektrische Leitungen in einem Schaltschrank, weist die Reihenklemme 1 Anschlussmittel 3a, 3b, 4a, 4b auf, die beispielsweise als Schraubklemmanschlüsse oder als Schneidklemmanschlüsse ausgeführt sind. Im gezeigten Ausführungsbeispiel sind die Anschlussmittel 3a und 3b über ein Verbindungsmittel 3c sowie die Anschlussmittel 4a und 4b über ein weiteres Verbindungsmittel 4c miteinander elektrisch leitend verbunden. Die Verbindungsmittel 3c, 4c sind beispielsweise als Metallstromleiter, insbesondere als Stromschienen, ausgeführt.For connecting and / or connecting electrical conductors, not shown, for example, electrical lines in a cabinet, has the
Die Anschlussmittel 3a, 3b, 4a, 4b und Verbindungsmittel 3c, 4c sind von einem mit dem Bezugszeichen 5 bezeichneten Gehäuse der Reihenklemme 1 gehalten, wobei die Verbindungsmittel 3c, 4c quer zur Richtung der Tragscheine 2 im Gehäuse 5 angeordnet sind.

Zur Erleichterung des Einbaus können der Einbauraum 8 und/oder das Modul 9 nicht dargestellte Führungsmittel aufweisen, beispielsweise kann der Einbauraum 8 mit Führungsschienen und das Modul 9 mit den Führungsschienen zugeordnete Führungsnuten aufweisen.

Zur Verhinderung von Falscheinbauten, d.h. um sicherzustellen, dass ein bestimmtes Modul 9 nur in einen bestimmten Einbauraum 8 einbaubar ist, können der Einbauraum 8 und/oder das Modul 9 Codierungsmittel aufweisen, beispielsweise kann das Modul 9 derart in seiner Form ausgestaltet sein, dass es sich nur in einen mit einem derart ausgeformten Modul 9 korrespondierenden Einbauraum 8 einbauen lässt. Entsprechendes gilt für die Einbauöffnung 15.To prevent false building, i. to ensure that a
Ein Beispiel für die Anwendung der Codierungsmittel sind unterschiedliche Überspannungsschutzvorschriften, die unterschiedliche Module 9 erfordern. Entsprechendes gilt für Module, die für unterschiedliche Spannungsbereiche ausgestaltet sind. Eine Codierung im oben beschriebenen Sinne kann auch durch eine farblicher Markierung von Einbauraum 8 und/oder Modul 9 erreicht werden, allein oder in Kombination mit den bereits geschilderten Codierungsmitteln.An example of the application of the coding means are different overvoltage protection regulations which require

Die Erfindung ist insbesondere nicht auf Reihenklemmen beschränkt, auch wenn die Erfindung aus Gründen der Verständlichkeit anhand einer solchen dargestellt wurde. Die Erfindung ist beispielsweise auch auf einen auf einer elektrischen Platine anordenbaren Anschlussblock anwendbar. Der externe Kontaktpunkt kann dann beispielsweise von einer auf der Platine angeordneten Massefläche gebildet werden.In particular, the invention is not limited to terminal blocks, even though the invention has been illustrated by way of clarity for the sake of clarity. For example, the invention can also be applied to a connection block which can be arranged on an electrical circuit board. The external contact point can then be formed, for example, by a ground plane arranged on the board.
Weiterhin ist es denkbar, den erfindungsgemäßen Anschlussblock mit weiteren funktionserweiternden Modulen zu bestücken. Im Rahmen der Erfindung ist es ebenfalls möglich den Anschlussblock so auszubilden, dass darin mehr als ein funktionserweiterndes Modul, beispielsweise ein Modul für einen Grob-Überspannungsschutz und ein Modul für einen Fein-Überspannungsschutz einbaubar sind.Furthermore, it is conceivable to equip the terminal block according to the invention with further function-expanding modules. In the context of the invention, it is also possible to design the terminal block in such a way that more than one function-expanding module, for example a module for a coarse overvoltage protection and a module for a fine overvoltage protection can be installed therein.
