Definitions
- the invention relates to a switch disconnector, the phase has two box terminals on a connector.
- the invention is therefore based on the object of providing a switch disconnector of the type mentioned above with improved connection technology which is simple to manufacture and which enables a plurality of electrical conductors to be connected.
- This object is achieved in that the connecting pieces each have at least two connecting webs formed by slots, and that each connecting web serves as a switching piece of a box terminal.
- the box terminals with the associated connecting webs are captively caulked. In this way, an inexpensive but completely adequate connection between the box terminals and the connecting webs is achieved in a simple manner.
- a particularly simple embodiment is obtained when two connecting webs are formed by a single slot in the outwardly directed broad side of the elongated connecting piece.
- One embodiment which enables a lateral exit of the conductors to be clamped, is obtained in that the connecting webs are formed by slots in at least one of the long sides of the elongated connecting piece.

Abstract
Description
Die Erfindung bezieht sich auf einen Lasttrennschalter, der Phase zwei Rahmenklemmen an einem Anschlußstück aufweist.The invention relates to a switch disconnector, the phase has two box terminals on a connector.
Eine derartige Ausführung ist in einem Herstellerkatalog (HOLEC, 1993, LOW-VOLTAGE SWITCHGEAR COMPONENTS) veröffentlicht. Unter anderem sind hier Anschlußstücke in Verbindung mit zwei Rahmenklemmen gezeigt. Damit ergibt sich die Möglichkeit, über ein Anschlußstück eines Lasttrennschalters zwei Leiter anzuschließen. Dem Katalog ist nicht zu entnehmen, in welcher Weise die feste Verbindung zwischen den beiden Rahmenklemmen und dem Anschlußstück hergestellt wird, sei es z.B. durch Verlötung oder Verschraubung. Diese Verbindung stellt jedenfalls eine zusätzliche kostensteigernde Maßnahme dar. Weiterhin ist zu bedenken, daß nur bis zu zwei Leiter angeklemmt werden können und darüber hinaus gehende Forderungen von der Anwenderseite her nicht erfüllt werden können.Such a version is published in a manufacturer catalog (HOLEC, 1993, LOW-VOLTAGE SWITCHGEAR COMPONENTS). Among other things, connectors are shown here in connection with two box terminals. This results in the possibility of connecting two conductors via a connection piece of a switch disconnector. The catalog does not show how the fixed connection between the two box terminals and the connector is made, e.g. by soldering or screwing. In any case, this connection represents an additional cost-increasing measure. Furthermore, it should be borne in mind that only up to two conductors can be connected and that further requirements cannot be met by the user.
Der Erfindung liegt daher der Aufgabe zugrunde, einen Lasttrennschalter der obengenannten Art mit verbesserter Anschlußtechnik zu schaffen, die in der Herstellung einfach ist und die einen Anschluß einer Vielzahl von elektrischen Leitern ermöglicht. Diese Aufgabe wird dadurch gelöst, daß die Anschlußstücke jeweils mindestens zwei durch Schlitze gebildete Anschlußstege haben, und daß jeder Anschlußsteg als Schaltstück einer Rahmenklemme dient. Gemäß einer vorteilhaften Ausführungsform sind die Rahmenklemmen mit den zugeordneten Anschlußstegen unverlierbar verstemmt. Hierdurch wird auf einfache Weise eine kostengünstige, jedoch völlig ausreichende Verbindung zwischen den Rahmenklemmen und den Anschlußstegen erreicht. Eine besonders einfache Ausführungsform erhält man, wenn zwei Anschlußstege durch einen einzigen Schlitz in der nach außen gerichteten Breitseite des länglich ausgeführten Anschlußstücks gebildet sind. Eine Ausführungsform, die einen seitlichen Abgang der anzuklemmenden Leiter ermöglicht, erhält man dadurch, daß die Anschlußstege durch Schlitze in mindestens einer der Längsseiten des länglich ausgeführten Anschlußstücks gebildet sind.The invention is therefore based on the object of providing a switch disconnector of the type mentioned above with improved connection technology which is simple to manufacture and which enables a plurality of electrical conductors to be connected. This object is achieved in that the connecting pieces each have at least two connecting webs formed by slots, and that each connecting web serves as a switching piece of a box terminal. According to an advantageous embodiment, the box terminals with the associated connecting webs are captively caulked. In this way, an inexpensive but completely adequate connection between the box terminals and the connecting webs is achieved in a simple manner. A particularly simple embodiment is obtained when two connecting webs are formed by a single slot in the outwardly directed broad side of the elongated connecting piece. One embodiment which enables a lateral exit of the conductors to be clamped, is obtained in that the connecting webs are formed by slots in at least one of the long sides of the elongated connecting piece.
Eine Ausführungsform der Neuerung wird im folgenden anhand einer Zeichnung näher erläutert. Es zeigen:

- FIG 2
- das Anschlußstück nach FIG 1
- FIG 3
- ein Anschlußstück für einen seitlichen Abgang
- FIG 4
- eine Seitenansicht eines geschlitzten Anschlußstückes mit aufgesteckter Rahmenklemme
- FIG 5
- die Draufsicht auf das mit einer Rabmenklemme versehene Anschlußstück gemäß FIG 4
- FIG. 1
- a switch disconnector with four connection options per connector
- FIG 2
- the connector according to FIG. 1
- FIG 3
- a connector for a side outlet
- FIG 4
- a side view of a slotted connector with attached box clamp
- FIG 5
- the top view of the connector provided with a Rabmenklemme according to FIG. 4th
In FIG 4,5 ist eine Ausführungsform gezeigt, bei der die Rahmenklemme 1 mit dem zugeordneten Anschlußstück 2 unverlierbar verstemmt ist, indem das Ende des Anschlußsteges 3, auf dem die Rahmenklemme 1 steckt, verquetscht ist.An embodiment is shown in FIG.
Sollten zum Beispiel die Raumverhältnisse einen seitlichen Abgang der anzuklemmenden Leiter erfordern, so ist dies möglich, indem das Anschlußstück 2 an seiner Längsseite mit Schlitzen 4 versehene wird, durch die wiederum Anschlußstege 3 für Rahmenklemmen 1 geschaffen werden (s. FIG 3).If, for example, the spatial conditions require a lateral outlet of the conductors to be clamped, this is possible by providing the
