Die Erfindung betrifft ein Installationsschaltgerät gemäß dem Oberbegriff des Anspruches 1. Ein Installationsschaltgerät der eingangs erwähnten Art wurde durch die DE 199 06 236 A bekannt. Bei diesem bekannten Schaltgerät ist als Hilfsschalter ein Mikroschalter vorgesehen, der über ein mit einem beweglichen Hauptkont.3kt gesteuertes Koppelelement betätigbar ist. Bei dieser Lösung ergibt sich das Problem, dass das Koppelelement, das als Schieber ausgebildet ist, einerseits eine Fehlerquelle darstellt und andererseits, da von außen auf das Installationsschaltgerät aufgesteckt, dessen Raumbedarf vergrößert. Außerdem weist ein Mikroschalter nur einen sehr kleinen Kontaktabstand auf, sodass der Mikroschalter aufgrund dessen geringer Baugröße nicht zum Schalten großer Betriebsströme verwendet werden k.ann Durch den geringen Abstand den dessen Schaltkontakte zueinander aufweisen kann eine sichere Trennung der an den Hilfsschalter angeschlossenen Leitungen nicht gew.ährleistet werden. Aufgabe der Erfindung ist es, diese Nachteile zu vermeiden und ein Installationsschaltgerät der eingangs erwähnten Art vorzuschlagen, bei dem der Hilfsschalter möglichst direkt in das elektrische Installationsschaltgerät integriert werden kann und auf einfache und teilesparende Weise den tatsächlichen Zustand der Schaltkontakte des elektrischen Installationsschaltgeräts anzeigt bzw. übernimmt. Weitere Aufgaben der Erfindung sind es, dass der Hilfsschalter eine sichere Trennung der Schaltkontakte ermöglicht bzw. aufweist und der Raumbedarf des Installationsschaltgerätes trotz Hilfsschalter im wesentlichen unvermdert bleibt. Erfindungsgemäß wird dies bei einem Installationsschaltgerät der eingangs erwähnten Art durch die kennzeichnenden Merkmale des Anspruches 1 erreicht.The invention relates to a service switching device according to the preamble of claim 1. An installation switching device of the type mentioned was known from DE 199 06 236 A.

In this solution, there is the problem that the coupling element, which is designed as a slide, on the one hand represents a source of error and on the other hand, as plugged from the outside on the service switching device, its space requirement increases. In addition, a microswitch has only a very small contact spacing, so that the microswitch can not be used for switching large operating currents due to its small size. The safe separation of the lines connected to the auxiliary switch can not be ensured by the small distance between the switching contacts. be ensured. The object of the invention is to avoid these disadvantages and to propose an installation switching device of the type mentioned, in which the auxiliary switch can be integrated as directly as possible in the electrical service switching device and displays the actual state of the switching contacts of the electrical service switching device in a simple and partially-saving manner , Other objects of the invention are that the auxiliary switch allows or has a safe separation of the switching contacts and the space required by the service switching device despite the auxiliary switch remains substantially unchanged. This is achieved according to the invention in an installation switching device of the type mentioned by the characterizing features of claim 1.
Durch die vorgeschlagenen Maßnahmen ist sichergestellt, dass der bewegliche Kontakt des Hilfsschalters direkt mit den Hauptkontakten durch die Schaltnocke gesteuert wird. Damit ist ein sehr direkter Zusammenhang zwischen der Stellung der Hauptkontakte und des Kontaktes des Hilfsschalters sichergestellt.The proposed measures ensure that the movable contact of the auxiliary switch is controlled directly to the main contacts through the switching cam. This ensures a very direct relationship between the position of the main contacts and the contact of the auxiliary switch.
Durch die kennzeichnenden Merkmale des Anspruches 2 ergibt sich durch den großen Ab- st.and der Kont.akte des Hilfsschalters eine sichere Trennung ebendieser Kontakte des Hilfsschalters, die durch einen Mikroschalter nicht zu erreichen ist. Damit brauchen an die Auslegung des dem Hilfsschalter nachgeordneten Stromkreises keine besonderen Anforderungen gestellt zu werden.Due to the characterizing features of claim 2 results from the large Ab.and the Kont.akte the auxiliary switch a safe separation ebendieser contacts of the auxiliary switch, which can not be reached by a microswitch.

Fig. 4 und 5 perspektivische Darstellungen des Hilfsschalters von zwei verschiedenen Seiten. Die besonders bevorzugte Ausfuhrungsform des erfindungsgemäßen Installationsschaltgeräts, z.B. eines Fehlerstrom-Schutzschalters, eines Leitungsschutzschalters od. dgl., weist ein Gehäuse 2 auf, das an seiner Rückseite eine Ausnehmung 3 für eine Montageschiene (nicht dargestellt) aufweist, wobei eine nicht dargestellte federnde Rasteinrichtung zur Nerrastung des Schaltgerätes 1 an der Montageschiene vorgesehen ist. In dem Gehäuse 2 sind Anschluss- klemmen 4 gehalten und es sind auch Aufnahmen 8 zum Aufstecken des Schaltgerätes an eine übliche Nerteilschiene mit Anschlusszungen vorgesehen. Weiters ist in dem Gehäuse 2 ein Hilfsschalter 5 eingesteckt, in dessen Anschlussklemmen 18 ein Anschlußstück 6 eingesteckt sein kann, was jedoch nicht unbedingt erforderlich ist. An der Norderseite des Schaltgerätes 1 sind Bedienorgane 9 und gegebenenfalls Anzeigen angeordnet (Fig. 2). Das Schaltgerät 1 enthält üblicherweise feste und bewegliche Kontakte (nicht dargestellt), von denen die letzteren über eine Schaltnocke, Schaltwelle oder Schaltwalze 10 (Fig. 3) gesteuert sind. Diese Schaltnocke ist von einem Bedienorgan 9, z.B. einer Handhabe gesteuert, wobei auch eine nicht dargestellte Auslöseeinrichtung auf die Schaltnocke 10 einwirkt. Die Schaltnocke 10, die mit ihren Steuerflächen 11 die nicht dargestellten Hauptkontakte steuert, weist eine mit einem Schlitz 12 ausgebildete Schaltscheibe 29 auf, in welchen Schlitz 12 ein beweglicher Kontakt 13, des Hilfsschalters 5, mit einer Zunge 14 eingreift, wodurch sichergestellt ist, dass der bewegliche Kontakt 13 des Hilfsschalters 5 sich stets in einer Stellung befindet, die jener der Schaltnocke 10 entspricht und damit auch der Stellung der Hauptkontakte des Schaltgerätes 1. Der Hilfsschalter 5 wird daher mit dem Schaltgerät 1 mitgeschalten.4 and 5 are perspective views of the auxiliary switch from two different sides. The particularly preferred embodiment of the installation switching device according to the invention, eg a residual current circuit breaker, a circuit breaker. The like., Has a housing 2, on its rear side a recess 3 for a mounting rail (not shown), wherein a not shown resilient locking device for Nerrastung the switching device 1 is provided on the mounting rail. In the housing 2 connection terminals 4 are held and there are also receptacles 8 provided for attaching the switching device to a conventional Nerteilschiene with connection tabs. Furthermore, an auxiliary switch 5 is inserted in the housing 2, in the terminals 18, a connector 6 may be inserted, which is not absolutely necessary. On the north side of the switching device 1 controls 9 and optionally displays are arranged (Fig. 2). The switching device 1 usually includes fixed and movable contacts (not shown), the latter of which are controlled via a switching cam, selector shaft or shift drum 10 (Figure 3). This switching cam is controlled by an operating element 9, for example a handle, wherein a triggering device, not shown, acts on the switching cam 10. The switching cam 10, which controls the main contacts, not shown, with its control surfaces 11, has a slot 12 formed with a switching disk 29, in which slot 12, a movable contact 13, the auxiliary switch 5, engages with a tongue 14, which ensures that the movable contact 13 of the auxiliary switch 5 is always in a position corresponding to that of the switching cam 10 and thus also the position of the main contacts of the switching device 1. The auxiliary switch 5 is therefore mitgeschalten with the switching device 1.
Der bewegliche Kontakt 13 des Hilfsschalters 5 ist mit einem durch eine Feder 15 bestimmten Sprungschaltwerk 16 versehen, wobei der bewegliche Kontakt 13 auf einer elektrisch leitenden gabelförmigen Aufnahme 17 sitzt. Dabei ist der bewegliche Kontakt 13 mit randoffenen Ausnehmungen versehen, die zur Aufnahme der beiden Zungen der gabelförmigen Aufnahme 17 vorgesehen sind.The movable contact 13 of the auxiliary switch 5 is provided with a designated by a spring 15 snap-action mechanism 16, wherein the movable contact 13 is seated on an electrically conductive fork-shaped receptacle 17. In this case, the movable contact 13 is provided with open-edged recesses which are provided for receiving the two tongues of the fork-shaped receptacle 17.
Diese gabelförmige Aufnahme 17 ist über eine Schiene 22 einstückig mit einem der gehäuse- seitig nach außen freigestellten Anschlußkontakte 18 (Fig. 2) des Hilfsschalters 5 verbunden. Erfindungsgemäß kann auch eine andere Ausführung des Sprungschaltwerkes vorgesehen sein.This fork-shaped receptacle 17 is connected in one piece via a rail 22 to one of the housing contacts 18 (FIG. 2) of the auxiliary switch 5 which is exposed to the outside of the housing. According to the invention, another embodiment of the snap-action mechanism can also be provided.
Dieser Hilfsschalter 5 ist als Wechselkontakt ausgebildet. Der bewegliche Kontakt 13 des Hilfsschalters 5 liegt daher an jeweils einem von zwei festen Kontakten 19, 20 an, die ebenfalls einstückig über Schienen 23, 24 mit weiteren Anschlußkontakten 18 des Hilfsschalters 5 verbunden sind.This auxiliary switch 5 is designed as a changeover contact. The movable contact 13 of the auxiliary switch 5 is therefore applied to one of two fixed contacts 19, 20, which are also integrally connected via rails 23, 24 with further connection contacts 18 of the auxiliary switch 5.
Zum Zwecke der Kontaktierung dieser Anschlußkontakte von außen wird - gegebenenfalls - das Anschlußstück 6 auf die Anschlußkontakte 18 aufgesteckt, wobei die Anschlußkontakte 18 dann zu Anschlussklemmen 7 durchverbunden sind .For the purpose of contacting these terminal contacts from the outside - if necessary - the connector 6 is attached to the terminal contacts 18, wherein the terminal contacts 18 are then connected through to terminals 7.
Das Gehäuse 21 des Hilfsschalter ist, wie aus der Fig. 5 zu ersehen ist, im wesentlichen L- formig ausgebildet, wobei ein in das Gehäuse 2 des Schaltgerätes 1 einschiebbarer Schenkel 30 mit einer vorspringenden Leiste 23 versehen ist, die in eine Nut 24 des Gehäuses 2 des Schaltgerätes 1 einschiebbar ist. Der zweite Schenkel des Gehäuses 21 des Hilfsschalters 5 liegt im eingeschobenen Zustand des Hilfsschalters 5 an der einen Anschlagfläche 25 des Gehäuses 2 an. Der Schenkel 30 des Gehäuses 21 weist an seiner einen Seite eine Freistellung 26 auf, durch die hindurch die Zunge 14 des beweglichen Kontaktes 13 tritt.The housing 21 of the auxiliary switch is, as can be seen from Fig. 5, formed substantially L-shaped, wherein a retractable into the housing 2 of the switching device 1 leg 30 is provided with a projecting strip 23 which in a groove 24 of Housing 2 of the switching device 1 can be inserted. The second leg of the housing 21 of the auxiliary switch 5 is in the inserted state of the auxiliary switch 5 at the one stop surface 25 of the housing 2 at. The leg 30 of the housing 21 has on its one side an exemption 26 through which the tongue 14 of the movable contact 13 passes.
Die Kontaktspalte zwischen dem beweglichen Kontakt 13 und den feststehenden Kontakten 19 und 20 sind ausreichend groß bemessen, um eine sichere Trennung der Kontakte zu gewährleisten. Dabei kann vorgesehen sein, dass der Hilfsschalter 5 einen ersten festen Kontakt 19 und einen zweiten festen Kontakt 20 aufweist, und dass der Abstand des ersten festen Kontakts 19 zum zweiten festen Kontakt 20 zumindest der Funkenstrecke bei der vorgesehenen Betriebsspannung, vorzugsweise zumindest der doppelten Funkenstrecke, entspricht. Durch den Kontaktspalt welcher bei einer besonders bevorzugten Ausfuhrungsform wenigstens lmm, vorzugsweise wenigstens 2mm, insbesondere wenigstens 3mm, beträgt, kann der nicht geschaltete Kontakt 19, 20 sicher elektrisch von dem, mit dem beweglichen Kontakt 13 in Verbindung stehenden festen Kontakt 20, 19 getrennt werden. Aufgrund des großen Öffnungsweges von einem festen Kontakt 19 zum andern festen Kontakt 20 den ein derartiger Schalter aufweist ist ein Überschlag von einem festen Kontakt 19, 20 zu einem anderen festen Kontakt 20, 19, bei den üblichen Betriebssp.annungen nicht zu erwarten. Unter Öf hungsweg wird der Abstand der beiden festen Kontakte 19, 20 zueinander verstanden.The contact gaps between the movable contact 13 and the fixed contacts 19 and 20 are dimensioned sufficiently large to ensure a secure separation of the contacts. It can be provided that the auxiliary switch 5 has a first fixed contact 19 and a second fixed contact 20, and that the distance of the first fixed contact 19 to the second fixed contact 20 at least the spark gap at the intended operating voltage, preferably at least twice the spark gap, equivalent. Due to the contact gap, which in a particularly preferred embodiment is at least 1 mm, preferably at least 2 mm, in particular at least 3 mm, the non-switched contact 19, 20 can be reliably electrically separated from the fixed contact 20, 19 which is in contact with the movable contact 13 , Due to the large opening path from a fixed contact 19 to the other fixed contact 20 having such a switch is a rollover of a fixed contact 19, 20 to another fixed contact 20, 19, not to be expected at the usual Betriebsssp.annungen.
