Description

Die Erfindung bezieht sich auf ein Schaltgerät mit einem Kontaktsystem, das eine Rahmenklemme und ein Kontaktstück umfasst, das fest eingebettet und mit einem angeschlossenen Leiter nicht mehr abhebbar ist, wobei die mechanische und elektrische Verbindung von Rahmenklemme (1) und Kontaktstück (2) in einer innigen Steckverbindung besteht. Ein gattungsgemäßes Schaltgerät ist aus der DE 295 01 277 U bekannt. Hier ist ein Sicherungslasttrenner mit Sicherungskontakten als Kontaktsystem offenbart, an die elektrisch leitende Verbindungsschienen angekoppelt sind. Das Kontaktsystem ist hier mit dem Gehäuse nicht fest verbunden, so daß es mit einem angeklemmten Leiter abhebbar ist.The invention relates to a switching device with a contact system, which comprises a box clamp and a contact piece, that firmly embedded and connected with one Head can no longer be lifted, the mechanical and electrical connection of box clamp (1) and contact piece (2) consists of an intimate plug connection. A generic switching device is from DE 295 01 277 U known. Here is a fuse switch disconnector with fuse contacts disclosed as a contact system to the electrically conductive Connection rails are coupled. The contact system is not firmly connected to the housing here, so that it with a clamped conductor can be lifted off.

Aus der DE 94 02 823 U ist ein Kontaktstück mit einer Kontaktfeder bekannt.DE 94 02 823 U describes a contact piece with a contact spring known.

Ein Schaltgerät, gemäß Oberbegriff des Anspruchs 1, ist aus GB-A-2059 191 bekannt.A switching device according to the preamble of claim 1 is from GB-A-2059 191 known.

Der Erfindung liegt die Aufgabe zugrunde, ein Schaltgerät mit einem Kontaktsystem der obengenannten Art zu schaffen, das bei einfachem Aufbau fest eingebettet und mit einem angeschlossenen Leiter nicht mehr abhebbar ist und geringe Übergangswiderstände gewährleistet.The invention has for its object to provide a switching device to create a contact system of the type mentioned above, the with a simple structure, firmly embedded and with a connected one Conductor can no longer be lifted and low contact resistance guaranteed.

Die Aufgabe wird mit den Merkmalen nach Anspruch 1 gelöst.The object is achieved with the features of claim 1.

Eine besonders einfache Ausführungsform besteht, wenn die Rahmenklemme über außenseitige Nuten mit dem Kontaktstück verbunden ist.A particularly simple embodiment is when the Box clamp via external grooves with the contact piece connected is.

Weitere vorteilhafte Ausgestaltungen der Erfindung sind den Unteransprüchen 2 und 3 zu entnehmen. Further advantageous embodiments of the invention are the Subclaims 2 and 3 can be found.

Ein Ausführungsbeispiel der Erfindung wird im folgenden anhand einer Zeichnung näher erläutert. Es zeigen:

FIG 1, 2, 3
verschiedene Ansichten eines beim erfindungsgemäßen Schaltgerät eingesetzten Kontaktsystems,
FIG 4
eine Vorderansicht der Rahmenklemme des Kontaktsystems,
FIG 5

An embodiment of the invention is explained below with reference to a drawing. Show it:
1, 2, 3
different views of a contact system used in the switching device according to the invention,
FIG 4
a front view of the box clamp of the contact system,
FIG 5
a plan view of the frame clamp of the contact system,
FIG 6
a switching device according to the invention with built-in contact system.

In FIG 1 ist die Vorderansicht eines aus einer Rahmenklemme 1 und einem Kontaktstück 2 zusammengesetzten Kontaktsystems dargestellt. Die Rahmenklemme 1 ist über außenseitige Nuten 3 mit dem Kontaktstück 2 verbunden. Hierzu weist das Kontaktstück 2 Schlitze 4 auf (siehe auch FIG 3), in die die Rahmenklemme 1 unter Eingriff des Kontaktstücks 2 in die Nuten 3 der Rahmenklemme 1 aufgeschoben ist.1 is a front view of a frame clamp 1 and a contact piece 2 composite contact system shown. The box clamp 1 is via grooves 3 on the outside connected to the contact piece 2. For this purpose, the contact piece 2 slots 4 (see also FIG 3) into which the box clamp 1 with the engagement of the contact piece 2 in the grooves 3 the box clamp 1 is pushed on.

FIG 2 bzw. 3 zeigen die Seitenansicht bzw. Draufsicht des Kontaktsystems. Die Rahmenklemme 1 weist gemäß FIG 4 ein Fenster 5 mit Schrägen 6 zur Zentrierung eines anzuklemmenden Leiters auf. FIG 5 zeigt eine Draufsicht der Rahmenklemme 1 mit einer Bohrung 7, die zum Leiteranschluß mit einem Gewinde ausgeführt ist.2 and 3 show the side view and top view of the Contact system. 4, the box terminal 1 has a window 5 with bevels 6 for centering a to be clamped Head on. 5 shows a top view of the box clamp 1 with a bore 7 leading to the conductor connection with a thread is executed.

Die Rahmenklemme 1 läßt sich aus einem gezogenen Profil herstellen, was eine Ablängung in beliebiger Länge gemäß dem Anwendungsfall ermöglicht.The box clamp 1 can be made from a drawn profile, what a length of any length according to the application allows.

Das vorbeschriebene Kontaktsystem ist gemäß FIG 6 in einer Kammer 8 eines Schaltgerätegehäuses 9 derart fixiert, daß das Kontaktstück 2 über zwei gegenüberliegene Ränder 9 in Nuten 10 von Seitenwänden 11 der Kammer 8 eingeschoben ist. Hierdurch wird ein optimaler Verdrehschutz für das Kontaktsystem gewährleistet. Das Kontaktsystem (1,2) ist fest eingebettet und mit einem angeschlossenen Leiter nicht mehr abhebbar.The contact system described above is shown in FIG Chamber 8 of a switchgear housing 9 fixed in such a way that Contact piece 2 over two opposite edges 9 in grooves 10 of side walls 11 of the chamber 8 is inserted. hereby becomes an optimal anti-twist protection for the contact system guaranteed. The contact system (1,2) is firmly embedded and can no longer be lifted off with a connected conductor.

Obwohl die vorliegende Erfindung unter Bezugnahme auf die in der beigefügten Zeichnung dargestellte Ausführungsform erläutert ist, sollte berücksichtigt werden, daß damit nicht beabsichtigt ist, die Erfindung nur auf die dargestellte Ausführungsform zu beschränken, sondern alle möglichen Änderungen, Modifizierungen und äquivalente Anordnungen, soweit sie vom Inhalt der Patentansprüche gedeckt sind, einzuschließen.Although the present invention with reference to the in of the accompanying drawing illustrated embodiment , it should be borne in mind that this is not intended is, the invention only to the illustrated embodiment to limit, but all possible changes, Modifications and equivalent arrangements insofar as they are from Contents of the claims are covered.
