Description

Die Erfindung betrifft ein Installationsschaltgerät in Sockelbauweise gemäß dem Oberbegriff des Anspruches 1.The invention relates to a service switching device in base construction according to the preamble of claim 1.

Installationsschaltgeräte in diesem Zusammenhang sind insbesondere Leitungsschutzschalter oder Federstromschutzschalter, die wenigstens eine Einfach- oder Doppelkontaktstelle aufweisen und deren Gehäuse etwa eine T- Form aufweist.Installation switching devices in this context are in particular circuit breaker or spring current circuit breaker having at least a single or double contact point and the housing has approximately a T-shape.

Zur Erfassung und Anzeige der Schaltstellung des Installationsschaltgerätes werden Hilfsschalter verwendet, die normalerweise die gleiche Außenkontur aufweisen wie das Installationsschaltgerät selbst und die seitlich an eine der Breitseitenflächen angesetzt werden. Über geeignete Kopplungselemente wird die Schaltstellung des beweglichen Kontaktstückes oder gegebenenfalls der Kontaktbrücke auf den Hilfsschalter übertragen, wodurch die Schaltstellung angezeigt wird.For detecting and displaying the switching position of the service switching device auxiliary switches are used, which normally have the same outer contour as the service switching device itself and the side are attached to one of the broad side surfaces. About suitable coupling elements, the switching position of the movable contact piece or optionally the contact bridge is transmitted to the auxiliary switch, whereby the switching position is displayed.

Aus der DE 199 06 236 A 1 ist eine andere Ausgestaltung der Anbringung eines Hilfsschalters bekannt geworden; danach wird der Hilfsschalter an die hintere Schmalseitenfläche angesetzt. Der Hilfsschalter ist ein Mikroschalter und das Gehäuse weist einen Vorsprung auf, der in eine Anschlußklemmenöffnung eingesteckt werden kann. Über einen mit einer Schrägfläche versehenen Schieber steht der Stößel des Mikroschalters mit dem beweglichen Kontaktstück oder dem beweglichen Kontakthebel in Verbindung. Wenn das Installationsschaltgerät in Ausschaltstellung geht, wird der Schieber entgegen dem Druck einer Feder verschoben und betätigt über die Schrägfläche den Mikroschalter.From the DE 199 06 236 A 1 another embodiment of the attachment of an auxiliary switch has become known; then the auxiliary switch is attached to the rear narrow side surface. The auxiliary switch is a microswitch and the housing has a projection which can be inserted into a terminal opening. About a provided with an inclined slide valve is the plunger of the microswitch with the movable contact piece or the movable contact lever in conjunction. When the service switching device is in the off position, the slider is moved against the pressure of a spring and actuates the microswitch via the inclined surface.

Innerhalb des Gehäuses für den Mikroschalter befinden sich Anschlußklemmen, die von der Frontseite zum Anschließen von Signalleitungen betätigt werden.Within the housing for the microswitch are terminals that are actuated from the front for connecting signal lines.

Aufgabe der Erfindung ist es, ein Installationsschaltgerät mit einem Hilfsschalter der eingangs genannten Art zu schaffen, bei dem die Montage vereinfacht ist und darüber hinaus auch eine übermäßige manuelle Kraft beim Anziehen der Klemmschrauben des Hilfsschalters keine Auswirdungen auf den Hilfsschalter hat.The object of the invention is to provide a service switching device with an auxiliary switch of the type mentioned, in which the assembly is simplified and beyond an excessive manual force when tightening the clamping screws of the auxiliary switch has no Auswirdungen on the auxiliary switch.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruches 1 gelöst.This object is achieved by the features of claim 1.

Danach besitzt das Installationsschaltgerät an den der hinteren Schmalseite anschließenden Breitseiten je eine parallel zur Schmalseite verlaufende Nut oder Leiste und am Hilfsschaltergehäuse sind parallel zu den Breitseiten in Richtung zur Schmalseite vorspringende Wandungsabschnitte angeformt, die den Nuten oder Leisten angepaßt sind, so daß das Hilfsschaltergehäuse senkrecht zur Befestigungsebene an der Schmalseite durch Einschieben von vorn zur Befestigungsebene hin am Installationsschaltgerät montierbar ist, wobei die an dem Wandungsabschnitten angeformten Vorsprünge oder Leisten in den Nuten oder Leisten an den Breitseiten gleiten.Thereafter, the service switching device has on the rear narrow side subsequent broadsides each one parallel to the narrow side groove or strip and the auxiliary switch housing parallel to the broad sides towards the narrow side projecting wall sections are formed, which are adapted to the grooves or strips, so that the auxiliary switch housing perpendicular to Fixing level on the narrow side can be mounted by inserting from the front to the mounting plane towards the service switching device, wherein the integrally formed on the Wandungsabschnitten projections or strips in the grooves or strips on the broad sides.

Auf diese Weise wird ein Verdrehschutz erreicht, weil die Fixierung des Hilfsschalters nicht durch Verklemmen, sondern formschlüssig erzielt wird.In this way, a Verdrehschutz is achieved because the fixation of the auxiliary switch is not achieved by jamming, but positively.

Damit der Hilfsschalter beim Einfügen eine bestimmte Endstellung nicht überschreitet, sind die der Befestigungsebene des Installationsschaltgerätes entgegengesetzt liegenden Enden der Wandungsabschnitte mittels einer Querwandung miteinander verbunden.Thus, the auxiliary switch does not exceed a certain end position when inserting the opposite ends of the mounting plane of the service switching device ends of the wall sections are connected to each other by means of a transverse wall.

Dadurch wird beim Einschieben erreicht, daß die Querwand gegen das Installationsschaltgerät anschlägt und auf diese Weise ein weiteres Einschieben verhindert.As a result, it is achieved during insertion that the transverse wall abuts against the service switching device and thus prevents further insertion.

Gemäß einer weiteren Ausgestaltungsform sind an der Schmalseitenfläche und an der der Schmalseitenfläche benachbarten Wandung des Hilfsschaltergehäuses Rastmittel angeformt, die zu einem Verrasten des Hilfsschaltergehäuses in seiner Endstellung dienen. Dabei kann am Hilfsschaltergehäuse eine Nase angeformt sein, die in eine Ausnehmung am Installationsschaltgerät einrastet.According to a further embodiment locking means are formed on the narrow side surface and on the narrow side surface adjacent wall of the auxiliary switch housing, which serve to lock the auxiliary switch housing in its end position. In this case, a nose can be integrally formed on the auxiliary switch housing, which engages in a recess on the service switching device.

Gemäß einer weiteren Ausgestaltung der Erfindung ist das Hilfsschaltergehäuse zweiteilig aufgebaut, mit einem Gehäuseunterteil und einem Gehäuseoberteil, welches quasi als Deckel wirkt. Das Gehäuseunterteil besitzt die Wandungsabschnitte, die Querwand und die Nase, wogegen das Gehäuseoberteil die Zugangsöffnungen zu den Klemmschrauben aufweist.According to a further embodiment of the invention, the auxiliary switch housing is constructed in two parts, with a lower housing part and an upper housing part, which acts as a kind of cover. The lower housing part has the wall sections, the transverse wall and the nose, whereas the upper housing part has the access openings to the clamping screws.

Weitere vorteilhafte Ausgestaltungen der Erfindung und weitere Verbesserungen sind den weiteren Unteransprüchen zu entnehmen.Further advantageous embodiments of the invention and further improvements can be found in the further subclaims.

Anhand der Zeichnungen, in der ein Ausführungsbeispiel der Erfindung dargestellt ist, sollen die Erfindung so wie weitere vorteilhafte Ausgestaltungen und Verbesserungen der Erfindung und weitere Vorteile näher erläutert und beschrieben werden.Reference to the drawings, in which an embodiment of the invention is shown, the invention as well as further advantageous embodiments and improvements of the invention and further advantages are explained and described.
