Description

Die Erfindung betrifft ein elektrisches Schaltgerät, insbesondere ein Reiheneinbaugerät zum Aufschnappen auf Profiltragschienen, mit einem Gehäuse in Schmalbauweise, mit einem an seiner Frontseite angeordneten Schaltgriff als Handbetätigungsorgan für wenigstens ein bewegliches Kontaktstück, welches mit wenigstens einem festen Kon­taktstück wenigstens eine Kontaktstelle bildet, mit we­nigstens zwei Anschlußklemmen, die über Verbindungslei­ter mit den Kontaktstücken verbunden sind und jeweils an den Schmalseiten des Gehäuses angeordnet sind, sowie mit einer an der Rückseite des Gehäuses angeordneten festen Rastnase und einem beweglichen Rastschieber, welche zur Befestigung an der Profiltragschiene dienen.The invention relates to an electrical switching device, in particular a modular device for snapping onto profile mounting rails, with a narrow housing, with a switching handle arranged on the front side as a manual actuating element for at least one movable contact piece, which forms at least one contact point with at least one fixed contact piece, with at least two Terminals which are connected to the contact pieces via connecting conductors and are each arranged on the narrow sides of the housing, as well as with a fixed latching lug arranged on the rear of the housing and a movable latching slide, which are used for fastening to the profile mounting rail.

Elektrische Schaltgeräte zum Einbau in Niederspannungs­verteilungen und in Zählerplätzen werden heute üblicher­weise in Schmalbauweise ausgeführt und aneinandergereiht auf Tragschienen befestigt. Für besondere Einsatzzwecke sind neben Selbstschaltern auch manuell betätigte Schaltgeräte im Einsatz, deren äußere Form der modulmä­ßigen Ausführung der Selbstschalter angepaßt ist, die aber bei voller Modulbreite mehrpolig ausgeführt sind. Dabei sind die einzelnen Schalterpole bei bekannten Ge­räten durch Isolierplatten, welche lose zwischen die Ge­hausehälften eingefügt sind, gegeneinander isoliert. Diese Isolierplatten, die als separates Teil vorgesehen sind, bestehen häufig aus Schichtstoff. Sie können aber auch als gespritzte Formplatte zum Einsatz kommen.Electrical switchgear for installation in low-voltage distributors and in metering stations are usually designed in a narrow construction today and attached to one another on mounting rails. For special purposes In addition to automatic switches, manually operated switching devices are also used, the external shape of which is adapted to the modular design of the automatic switch, but which are multi-pole with the full module width. In the case of known devices, the individual switch poles are isolated from one another by insulating plates which are loosely inserted between the housing halves. These insulating plates, which are provided as a separate part, often consist of laminate. However, they can also be used as a molded plate.

Bei derartigen mit zwischen den Gehäusehälften befindli­chen Isolierplatten kann es infolge von durch die Trenn­fuge der Gehäusehälften eindringenden Staub- und Schmutzpartikeln zu Kontaktunterbrechungen beim Ein­schalten des Gerätes kommen. In der Folge können ferner durch Anlagerung leitender Teilchen an den Isolierstoff­wänden, die durch die insbesondere bei hohen Stromstär­ken auftretenden Schaltlichtbögen verursacht sind, Kriechstromstrecken entstehen, welche zu unerwünschten Uberschlägen führen, was durch die dabei verringerten dielektrischen Abstände begünstigt ist.In the case of insulating plates of this type located between the housing halves, dust and dirt particles penetrating through the parting line of the housing halves can lead to contact interruptions when the device is switched on. As a result, conductive particles can also build up on the insulating walls, which are caused by the switching arcs that occur in particular at high currents, which can lead to undesired arcing, which is favored by the reduced dielectric spacing.

Unter Berücksichtigung der zuvor dargelegten Schwierig­keiten hat die Erfindung die Aufgabe, ein Schaltgerät der eingangs genannten Art anzugeben, das eine möglichst kostengünstige Herstellung erlaubt und bei dem die ge­schilderten Nachteile vermieden sind.Taking into account the difficulties outlined above, the object of the invention is to provide a switching device of the type mentioned at the outset which allows the most cost-effective production possible and in which the disadvantages described are avoided.

Die erfindungsgemäße Lösung der Aufgabe ist dadurch ge­kennzeichnet, daß das Gehäuse einen Mittelsockel be­sitzt, welcher die Kontaktstücke und die Anschlußklemmen aufnimmt und auf seinen Flachseiten sowie auf seiner Frontseite und Rückseite von zwei Deckeln umschlossen ist, die zur Frontseite hin den Mittelsockel überragen und zur Halterung des Schaltgriffes dienen.The inventive solution to the problem is characterized in that the housing has a central base, which receives the contact pieces and the terminals and is enclosed on its flat sides and on its front and back by two lids that protrude towards the front of the central base and to hold the Serve switch handle.

In vorteilhafter Ausgestaltung der Erfindung ist vorge­sehen, daß der Mittelsockel ein Bodenteil aufweist, wel­ches an der Rückseite des Gehäuses angeordnet ist und mit einer den Mittelsockel in einen ersten und in einen zweiten Bereich unterteilenden Zwischenwand, die zwi­schen den beiden Schmalseiten parallel zu den beiden Deckeln angeordnet ist, einstückig verbunden ist. Diese Zwischenwand besitzt auf ihren beiden Flachseiten spie­gelbildlich angeformte labyrinthartige Ansätze, die zur Aufnahme und Führung der Kontaktstücke, Verbindungslei­ter sowie der Anschlußklemmen dienen. Dabei erweist es sich als vorteilhaft, die Ansätze, welche die Anschluß­klemmen sowie die Verbindungsleiter und Kontaktstücke zumindest streckenweise beidseitig einfassen, in glei­cher Tiefe auszuführen, so daß sich eine ebene Montage­fläche am Zwischensockel ergibt, die eine Automatisie­rung der Montage ermöglicht.In an advantageous embodiment of the invention it is provided that the central base has a base part which is arranged on the rear of the housing and with an intermediate wall which divides the central base into a first and a second area and which is arranged parallel to the two covers between the two narrow sides is connected in one piece. This partition has, on its two flat sides, mirror-image shaped labyrinth-like approaches which serve to receive and guide the contact pieces, connecting conductors and the connecting terminals. It proves to be advantageous to carry out the approaches, which at least in sections on both sides connect the connecting terminals and the connecting conductors and contact pieces, at the same depth, so that there is a flat mounting surface on the intermediate base, which enables the assembly to be automated.

Bei einer bevorzugten Ausgestaltung der Erfindung kann vorgesehen sein, daß jeder Bereich einen Schieber zur Betätigung der diesen Bereich zugehörigen beweglichen Kontaktstücke aufweist, der mit dem Schaltgriff in Ein­griff steht. Ein solcher Schieber besitzt eine Schiebe­achse, die vertikal zum Bodenteil verläuft und beider­seits der Zwischenwand in deren Mitte angeordnet ist. Entsprechend vorbereitete Ansätze bilden hierbei eine Führung für den Schieber.In a preferred embodiment of the invention it can be provided that each area has a slide for actuating the movable contact pieces associated with this area, which slide is in engagement with the control handle. Such a slide has a sliding axis that runs vertically to the bottom part and is arranged on both sides of the intermediate wall in the middle thereof. Appropriately prepared approaches form a guide for the slide.

Gemäß einer anderen bevorzugten Ausgestaltung der Erfin­dung ist ein gemeinsamer Schieber für beide Bereiche des Mittelsockels vorgesehen, der zur gleichzeitigen Betäti­gung der auf beiden Seiten der Zwischenwand angeordneten beweglichen Kontaktstücke dient und ebenfalls mit dem Schaltgriff in Eingriff steht. Bei dieser Ausgestaltung ist der Schieber, der ebenfalls eine vertikal zum Boden­teil verlaufende Schieberachse besitzt, in einer in der Mitte der Zwischenwand vorgesehenen Ausnehmung, die sich vom Bodenteil bis zur Frontseite erstreckt, geführt. In diesem Fall ist der Schieber in einer solchen Dicke aus­geführt, daß er mit dem Mittelsockel jeweils bündig ab­schließt. Auch hier können zusätzliche Ansätze an der Zwischenwand vorgesehen sein, welche die Führung des Schiebers verbessern, z. B. um ein Verkanten zu verhin­dern.According to another preferred embodiment of the invention, a common slide is provided for both areas of the center base, which serves for the simultaneous actuation of the movable contact pieces arranged on both sides of the intermediate wall and is also in engagement with the control handle. With this configuration the slide, which also has a slide axis running vertically to the base part, is guided in a recess provided in the middle of the intermediate wall, which extends from the base part to the front. In this case, the slide is of such a thickness that it is flush with the center base. Here, too, additional approaches can be provided on the intermediate wall, which improve the guidance of the slide, e.g. B. to prevent tilting.

Gemäß der Erfindung erweist es sich als vorteilhaft, die Verbindungsleiter als Flachleiter auszuführen, deren Schmalseiten in die taschenähnlichen labyrinthartig ge­stalteten Ansätze an der Zwischenwand greifen und von diesen bezüglich ihrer Breite voll überdeckt sind.According to the invention, it proves to be advantageous to design the connecting conductors as flat conductors, the narrow sides of which engage in the pocket-like, labyrinth-like approaches on the intermediate wall and are completely covered by these with respect to their width.

Die Anschlußklemmen sind in bekannter Weise als Hubklem­men ausgebildet und werden in die von den paßgenau ange­formten Ansätzen gebildeten Räume mit leichtem Druck eingesetzt, wobei sich eine Klemmwirkung einstellt, die ein unbeabsichtigtes Herausgleiten der Anschlußklemmen aus dem Zwischensockel verhindert. Hierbei greifen die Verbindungsleiter, deren Breite der der Anschlußklemme entspricht, mit einem Ende in die Aufnahmeöffnung der Anschlußklemme. In vorteilhafter Weise ist hierbei an den beiden Schmalseiten jeweils eine Einformung vorgese­hen, der zufolge die Verbindungsleiter in diesem Bereich eine Breite entsprechend der lichten Weite der Aufnahme­öffnung der Anschlußklemme haben. Am Ende dieser Einfor­mung erreicht der jeweilige Verbindungsleiter wieder sein ursprüngliches Breitenmaß, so daß auf diese einfa­che Weise eine sichere formschlüssise Verankerung in der Anschlußklemme bereits ohne besonderen Klemmeffekt durch die Klemmschraube erreicht wird.The terminals are designed in a known manner as lifting terminals and are inserted into the spaces formed by the precisely formed approaches with slight pressure, a clamping effect being established which prevents the terminals from slipping unintentionally out of the intermediate base. Here, the connecting conductors, the width of which corresponds to that of the connecting terminal, engage with one end in the receiving opening of the connecting terminal. Advantageously, a molding is provided on each of the two narrow sides, according to which the connecting conductors in this area have a width corresponding to the clear width of the receiving opening of the connecting terminal. At the end of this shaping, the respective connecting conductor again reaches its original width dimension, so that in this simple manner a secure, form-fitting anchoring in the connecting terminal is achieved without a special clamping effect using the clamping screw.

In besonderer Ausgestaltung der Erfindung ist es ferner vorgesehen, die Kontaktstellen mit zwei festen Kontakt­stücken auszugestalten, die durch ein als Brückenelement ausgebildetes bewegliches Kontaktstück miteinander ver­bunden werden. Dieses bewegliche Kontaktstück ist an dem bereits erwähnten Schieber federnd befestigt, so daß un­abhängig von irgendwelchen toleranzbedingten Schieflagen sowohl der Kontaktstücke als auch des Schiebers die Kon­taktstücke jeweils mit ausreichender Auflage sowie Kon­taktkraft zusammenarbeiten.In a special embodiment of the invention, it is further provided to design the contact points with two fixed contact pieces which are connected to one another by a movable contact piece designed as a bridge element. This movable contact piece is resiliently attached to the already mentioned slide, so that regardless of any tolerance-related inclinations of both the contact pieces and the slide, the contact pieces each work together with sufficient support and contact force.

Eine bevorzugte Ausgestaltung der Erfindung sieht vor, daß die beim erfindungsgemäßen Schaltgerät zum Einsatz kommenden Kontaktstücke aus Flachleitern gebildet sind, die an ihren in die Kontaktstelle reichenden Ende mit einem Kontaktplättchen versehen sind, welches ausrei­chende Lichtbogenbeständigkeit aufweist. Dabei ist daran gedacht, die festen Kontaktstücke einstückig mit dem je­weiligen Verbindungsleiter zur zugeordneten Anschluß­klemme zu verbinden. Die beweglichen Kontaktstücke hin­gegen sind als Traversen aus Flachleitermaterial ausge­staltet, wobei ihre Länge auf den Abstand der Kontakt­plattchen der beiden einander zugeordneten Festkontakt­stücke angepaßt ist. An den beiden Enden der Traverse ist jeweils ein Kontaktplättchen befestigt, welches mit dem gegenüberliegenden am jeweils zugeordneten Festkon­taktstück befestigten Kontaktplättchen fluchtet. Zur Be­festigung der beweglichen Kontaktstücke besitzt der er­findungsgemäße Schieber Querschlitze, in welche die Tra­versen der beweglichen Kontaktstücke jeweils eingelegt und von in hierfür beiderseits der Zwischenwand vorgese­henen Ausnehmungen des Schiebers angeordneten Druckfe­dern derart beaufschlagt sind, daß die Traversen zwi­schen der Druckfeder und den Schlitzkanten jeweils ein­geklemmt sind. Ein seitliches Verrutschen der Traversen ist dadurch verhindert, daß an der Traverse jeweils beidseitig in der Mitte Vorsprünge angeformt sind, die in eine im Schieber hierfür vorgesehene Längsnut greifen und gleichzeitig in einer lagerichtig zugerodnet in den jeweiligen Deckel eingeformten Nut geführt sind.A preferred embodiment of the invention provides that the contact pieces used in the switching device according to the invention are formed from flat conductors which are provided at their end reaching into the contact point with a contact plate which has sufficient resistance to arcing. It is contemplated to connect the fixed contact pieces in one piece with the respective connecting conductor to the associated terminal. The movable contact pieces, on the other hand, are designed as traverses made of flat conductor material, their length being adapted to the distance between the contact plates of the two fixed contact pieces assigned to one another. A contact plate is attached to each of the two ends of the crossbar, which is aligned with the opposite contact plate attached to the associated fixed contact piece. To fasten the movable contact pieces, the slide according to the invention has transverse slots into which the traverses of the movable contact pieces are each inserted and acted upon by compression springs arranged in recesses of the slide provided on both sides of the intermediate wall such that the crossbars are clamped between the compression spring and the slot edges. Lateral slipping of the trusses is prevented by the fact that projections are formed on both sides in the middle of the crossmember, which engage in a longitudinal groove provided for this purpose in the slide and at the same time are guided in a groove formed in the correct position in the respective cover.

Die beiden Deckel sind gemäß der Erfindung ebenfalls mit labyrinthartigen Ansätzen versehen, die in den Mittel­sockel greifen und so eine zusätzliche Verankerung der Kontaktstücke, Verbindungsleiter sowie der Anschlußklem­men bewirken. An der Gehäuserückseite ist in die Deckel jeweils eine Ausnehmung eingelassen, die zur Aufnahme einer Tragschiene zum Aufschnappen dient. Hierzu besitzt jeder Deckel in spiegelbildlicher Anordnung zum gegen­überliegenden Deckel eine feste Rastnase, die ebenfalls an den flachen Bereich des Deckels angeformt ist und die halbe Gehäusedicke erreicht, sowie eine Führung für ei­nen zwischen die Deckel einzusetzenden beweglichen Rast­schieber, der die Tragschiene hintergreift und von bei­den Deckeln gehalten und geführt ist.According to the invention, the two lids are also provided with labyrinth-like approaches which engage in the central base and thus bring about additional anchoring of the contact pieces, connecting conductors and the connecting terminals. On the back of the housing there is a recess in the cover, which is used to hold a mounting rail for snapping on. For this purpose, each cover has a fixed locking lug in a mirror-image arrangement to the opposite cover, which is also molded onto the flat area of the cover and reaches half the thickness of the housing, as well as a guide for a movable locking slide to be inserted between the covers, which engages behind the mounting rail and from both covers is held and managed.

In vorteilhafter Weise ist beim erfindungsgemäßen Schaltgerät weiterhin vorgesehen, daß auf beiden Seiten des Zwischensockels wenigstens zwei voneinander unabhän­gige Schaltebenen vorgesehen sind, die übereinander, d. h. zwischen Bodenteil und Frontseite, angeordnet sind. Dementsprechend sind die an die Zwischenwand angeformten Ansätze angeordnet, wobei zwischen den zuvor erwähnten Schaltebenen ein als Trennwand dienender durchgehender Ansatz an die Zwischenwand angeformt ist, der lediglich von dem Schieber unterbrochen ist. Auf diese Weise sind auf jeder Seite des Zwischensockels zwei Schaltkammern gebildet, in welchen die Festkontakte wahlweise oben, d. h. zur Frontseite gerichtet, als Öffnerkontakte oder unten, d. h. zum Bodenteil gerichtet, als Schließerkon­takte vorgesehen sind. Damit ist es möglich vier voneinander unabhängige Schaltvorgänge, z. B. zwei Schließungen und zwei Öffnungen oder eine Öffnung und drei Schließungen, auszuführen. Gemäß einer weiteren vorteilhaften Ausgestaltung der Erfindung ist es vorgesehen, die Zwischenwand des Mittelsockels in den einzelnen Schaltkammern bedarfsweise mit Durchbrüchen zu versehen, welche nebeneinander liegende nur durch die Zwischenwand voneinander getrennte Schaltkammern miteinander verbinden und es gestatten, den Verbindungsleiter hindurchzuführen, so daß die Anschluß­klemme für eine Schaltkammer sowohl mit dem zu dieser Schaltkammer gehörigen Festkontakt als auch mit dem in der benachbarten Schaltkammer verbunden ist. Auch hier sieht die Erfindung vor, daß die Verbindungsleiter so geführt sein können, daß die Festkontakte wahlweise als Schließer- oder als Öffnerkontakte angeordnet sind. Auch ist es möglich, die Verbindungsleiter so zu gestalten, daß der Festkontakt in der einen Schaltkammer als Schließerkontakt hingegen in der benachbarten Schaltkam­mer als Öffnerkontakt bzw. umgekehrt geschaltet sind.In an advantageous manner, it is further provided in the switching device according to the invention that at least two mutually independent switching planes are provided on both sides of the intermediate base, which are arranged one above the other, ie between the base part and the front side. The lugs formed on the intermediate wall are arranged accordingly, a continuous lug serving as a partition being formed on the intermediate wall between the switching levels mentioned above, which is only interrupted by the slide. In this way, two switching chambers are formed on each side of the intermediate base, in which the fixed contacts optionally at the top, ie directed towards the front, as break contacts or below, ie directed towards the bottom part, are provided as make contacts. This makes it possible to perform four independent switching operations, e.g. B. two closings and two openings or one opening and three closings. According to a further advantageous embodiment of the invention, it is provided, if necessary, to provide the intermediate wall of the central base in the individual switching chambers with openings which connect adjacent switching chambers which are only separated from one another by the intermediate wall and allow the connecting conductor to be passed through, so that the connecting terminal for a switching chamber is connected both to the fixed contact belonging to this switching chamber and to that in the neighboring switching chamber. Here, too, the invention provides that the connecting conductors can be guided in such a way that the fixed contacts are arranged either as NO contacts or as NC contacts. It is also possible to design the connecting conductors in such a way that the fixed contact in the one switching chamber as the normally open contact is switched in the adjacent switching chamber as the normally closed contact or vice versa.

Der zur Betätigung der beweglichen Kontaktstücke vorge­sehene Schieber ist vorzugsweise als U-Profilstab aus Isolierstoff gebildet, wobei jeweils an seinen Enden und in der Mitte angeordnete Querstege vorgesehen sind, an welchen sich die Druckfedern für die Traversen der be­weglichen Kontaktstücke abstützen. Die Schlitze, in de­nen die Traversen im Schieber geführt sind, weisen vor­teilhafter Weise eine Schlitzbreite auf, die den Traver­sen ausreichendes Spiel gewährt zum Ausgleich unter­schiedlicher Kontaktlagen der Festkontaktstücke, wobei die Kontaktdruckfedern eine elastische Verbindung der Traversen mit den Schiebern herstellen.The slider provided for actuating the movable contact pieces is preferably formed as a U-shaped rod made of insulating material, transverse webs being provided at each of its ends and in the middle, on which the compression springs for the cross members of the movable contact pieces are supported. The slots in which the crossbeams are guided in the slide advantageously have a slot width which allows the crossbeams sufficient play to compensate for different contact positions of the fixed contact pieces, the contact pressure springs producing an elastic connection between the crossbeams and the slide bars.

Ein weiteres vorteilhaftes Merkmal der erfindungsgemäßen Ausgestaltung des Schiebers betrifft eine Feder, die den Schieber in einer Richtung beaufschlagt und dadurch ei­nerseits zur einwandfreien Kontaktierung beiträgt und andererseits definierte Schaltzustände sicherstellt, die über das an einem Ende des Schiebers angreifende Handbe­tätigungsorgan auf den Schieber übertragen werden. Vor­zugsweise ist vorgesehen, daß die den Schieber beauf­schlagende Feder eine Schraubendruckfeder ist, die zwi­schen dem Bodenteil des Mittelsockels und der diesem ge­genüberliegenden Stirnseite des Schiebers angeordnet ist. Auf der gegenüberliegenden Stirnseite des Schiebers greift das als schwenkbarer Schaltgriff ausgebildete Handbetätigungsorgan über einen Verbindungshebel an. Hierbei wird durch schwenken des Schaltgriffes aus der Schwenkbewegung mit Hilfe des Verbindungshebels dem Schieber eine translatorische Bewegung aufgeprägt, die die beweglichen Kontaktstücke aus der einen Schaltposi­tion in die andere Schaltposition bringt.Another advantageous feature of the design of the slide according to the invention relates to a spring which acts on the slide in one direction and thereby on the one hand contributes to proper contacting and on the other hand ensures defined switching states which are transmitted to the slide via the manual control element acting on one end of the slide. It is preferably provided that the spring acting on the slide is a helical compression spring which is arranged between the base part of the central base and the end face of the slide opposite this. On the opposite end of the slide, the manual control element, which is designed as a pivotable control handle, engages via a connecting lever. In this case, a translational movement is imparted to the slide by pivoting the switching handle from the pivoting movement with the aid of the connecting lever, which translates the movable contact pieces from one switching position to the other switching position.

In weiterer vorteilhafter Ausgestaltung des erfindungs­gemäßen Schaltgerätes kann eine Anzeigevorrichtung vor­gesehen sein, die an der Stirnseite des Gehäuses ange­ordnet ist. Es handelt sich dabei um ein Leuchtelement, welches elektrisch so geschaltet ist, daß es bei der einen Schaltposition leuchtet und beim Ubergang in die andere Schaltposition erlischt. Hierzu ist ferner vorge­sehen, daß in dem die Stirnseite übergreifenden Deckel des Gehäuses eine Ausnehmung angeordnet ist, die durch ein durchsichtiges Teil ausgefüllt ist, welches die An­zeige des Leuchtelementes erkennen läßt.In a further advantageous embodiment of the switching device according to the invention, a display device can be provided, which is arranged on the end face of the housing. It is a light-emitting element which is electrically switched so that it lights up in one switching position and goes out during the transition to the other switching position. For this purpose, it is further provided that a recess is arranged in the cover of the housing which overlaps the end face and is filled by a transparent part which shows the display of the lighting element.

Diese und weitere vorteilhafte Ausgestaltungen der Er­findung sind in den Unteransprüchen angegeben.These and further advantageous refinements of the invention are specified in the subclaims.

Anhand eines in der Zeichnung dargestellten Ausführungs­beispieles sollen die Erfindung, vorteilhafte Ausgestal­tungen und besondere Vorteile der Erfindung näher erläu­tert und beschrieben werden.The invention, advantageous refinements and particular advantages of the invention are to be explained and described in more detail with reference to an exemplary embodiment shown in the drawing.

In Figur 1 ist die Schrägansicht eines elektrischen Schaltgerätes 10 wiedergegeben, dessen in Schmalbauweise ausgeführtes Gehäuse 11 aus einem Mittelsockel 14 gebildet ist, der an seinen beiden Flachseiten von jeweils einem Deckel 12 und 16 bedeckt ist, die mittels durch auf den Flachseiten angeordneter Durchgangsbohrungen 16 geführter, nicht gezeigter Halteelemente zusammengehalten sind.In Figure 1, the oblique view of an electrical switchgear 10 is shown, the narrow housing 11 is formed from a center base 14, which is covered on its two flat sides by a cover 12 and 16, respectively, which is guided by through holes 16 arranged on the flat sides holding elements, not shown, are held together.

Der Mittelsockel 14 besitzt insgesamt vier Schalterpole 20, 22, 24, 26, die paarweise nebeneinander, getrennt durch eine Zwischenwand 15, in zwei Ebenen übereinander angeordnet sind und deren Anschlußklemmen 28 über Betä­tigungsöffnungen 30 zugänglich sind. Die Betätigungsöff­nungen 30 sind für die obere Ebene, wie in Figur 2 bzw. 4 erkennbar, versetzt gegenüber der unteren Ebene ange­ordnet, um so auch den Zugang zu den Anschlußklemmen 28 der unteren Ebene zu ermöglichen.The center base 14 has a total of four switch poles 20, 22, 24, 26, which are arranged in pairs next to one another, separated by an intermediate wall 15, in two levels one above the other and whose connecting terminals 28 are accessible via actuating openings 30. The actuating openings 30 for the upper level, as can be seen in FIGS. 2 and 4, are arranged offset with respect to the lower level, in order in this way also to allow access to the connecting terminals 28 of the lower level.

An der schmalen Frontseite des Schaltgerätes 10, die in den Figuren 1, 2, 3, 5 jeweils nach oben weist, ist ein Schaltgriff 32 zur Betätigung der Schalterpole 20, 22, 24, 26 des Schaltgerätes 10 angeordnet. Dieser Schaltgriff 32 ist schwenkbar in den beiden den Mittelsockel an der Frontseite überragenden Deckeln 12, 16 geführt, wobei der Deckel 16 eine quaderförmige angesetzte Haube 17 aufweist, die vom Schaltgriff 32 durchgriffen ist und den Mittelsockel 14 mit Ausnahme der Betätigungsöffnungen 30 frontseitig überdeckt und sich am gegenüberliegenden Deckel 12 abstützt. Unmittelbar neben dem Schaltgriff 32 ist ein lichtdurchlässiger Streifen 34 in die Haube eingesetzt, der zu einer Schaltstellungsanzeige gehört. Parallel hierzu ist eine ω -förmige Nut 36 in die Haube 17 eingeformt, die zur Aufnahme einer hier nicht gezeigten Gerätekennzeichnung dient.A switching handle 32 for actuating the switch poles 20, 22, 24, 26 of the switching device 10 is arranged on the narrow front side of the switching device 10, which points upwards in FIGS. 1, 2, 3, 5. This control handle 32 is pivotally guided in the two lids 12, 16 projecting beyond the central base on the front, the cover 16 having a cuboid-shaped hood 17 which is penetrated by the control handle 32 and which covers the central base 14 with the exception of the actuating openings 30 on the front and itself supported on the opposite cover 12. Immediately next to the control handle 32, a translucent strip 34 is inserted into the hood, which belongs to a switch position indicator. In parallel with this, an ω-shaped groove 36 is formed in the hood 17, which is used to hold a device identifier, not shown here.

An den seitlichen Schmalseiten des Schaltgerätes 10 sind Zuführungsöffnungen 38 vorgesehen, die den den einzelnen Schalterpolen 20, 22, 24, 26 zugehörigen Anschlußklemmen 28 zugeordnet sind. Wie aus den Figuren 2 und 3 zu ent­nehmen ist, befinden sich diese Zuführungsöffnungen 38 im Mittelsockel 14 und sind nach den Flachseiten hin jeweils von den Deckel 12, 16 abgedeckt. Im Bereich der zu den oberen Schalterpolen 20, 22 gehörigen Zuführungs­öffnungen 38 sind die Deckel 12, 16, jeweils mit vorge­kerbten Ausbruchflächen 39 versehen, welche bei Bedarf ausbrechbar sind, wie in Figur 1 rechte Seite gezeigt, und den Zugang zu den oberen Zuführungsöffnungen 38 von der Flachseite aus gestatten.On the narrow sides of the switching device 10, supply openings 38 are provided which are assigned to the connecting terminals 28 associated with the individual switch poles 20, 22, 24, 26. As can be seen from FIGS. 2 and 3, these feed openings 38 are located in the central base 14 and are each covered by the covers 12, 16 on the flat sides. In the area of the supply openings 38 belonging to the upper switch poles 20, 22, the covers 12, 16 are each provided with pre-notched cut-out surfaces 39, which can be broken out if necessary, as shown in the right side in FIG. 1, and provide access to the upper supply openings 38 from allow the flat side.

Die Kontur der das Schaltgerät 10 einfassenden Deckel 12, 16 ist angepaßt an die der bekannten Reiheneinbauge­räte in Schmalbauweise, z. B. von Leitungsschutzschal­tern, die auf Tragschienen aufschnappbar sind. Demgemäß besitzen auch die Deckel 12, 16 an ihrer der schmalen Frontseite entgegengesetzten Rückseite jeweils eine Ausnehmung 40, die zur Aufnahme einer nicht dargestellten Profiltragschiene dient und jeweils von einer festen Haltenase 42 und einem in Figur 2 erkennbaren, von beiden Deckeln 12, 16 geführten beweglichen Rastschieber 44 begrenzt ist.The contour of the switchgear 10 enclosing cover 12, 16 is adapted to that of the known modular devices in narrow construction, for. B. of circuit breakers that can be snapped onto mounting rails. Accordingly, the lids 12, 16 each have a recess 40 on their rear side opposite the narrow front side, which serves to receive a profile support rail, not shown, and each have a fixed retaining lug 42 and a movable lug, which can be seen in FIG. 2 and is guided by both lids 12, 16 Latch slide 44 is limited.

Während in Figur 1 die äußere Gestaltung des Schaltgerä­tes 10 gezeigt ist, zeigt Figur 2 die Ansicht der Flach­seite des Schaltgerätes 10 bei abgenommenen Deckel 12 und gibt so den Blick frei auf die diesseitigen Schal­terpole 22 und 26, die jeweils bewegliche Kontaktstücke 50 und feste Kontaktstücke 52 besitzen.While the external design of the switching device 10 is shown in FIG. 1, FIG. 2 shows the view of the flat side of the switching device 10 with the cover 12 removed and thus gives a clear view of the switch poles 22 and 26 on this side, the movable contact pieces 50 and fixed contact pieces 52 have.

Die bereits zuvor erläuterten Schalterbauteile des Schaltgerätes 10 sind jeweils mit denselben Bezugszif­fern versehen, so daß nur bedarfsweise hierauf noch wei­ter eingegangen werden soll.The switch components of the switching device 10 which have already been explained above are each provided with the same reference numerals, so that this will only be discussed further if necessary.

Zu erkennen ist die versetzte Anordnung der der oberen Ebene zugehörigen Anschlußklemmen 28 gegenüber denen der unteren Ebene, wobei in Figur 2 nur der Bereich des Mit­telsockels zu sehen ist, der zwischen der Zwischenwand 15 und dem Deckel 12 angeordnet ist. Die Zwischenwand 15 ist einstückig mit einem Bodenteil 13 verbunden, welches von einer Schmalseite des Mittelsockels 14 zur anderen Schmalseite reicht und an der Rückseite des Schaltgerä­tes 10 angeordnet ist.The staggered arrangement of the connecting terminals 28 belonging to the upper level can be seen compared to those of the lower level, only the area of the central base which is arranged between the intermediate wall 15 and the cover 12 being shown in FIG. The intermediate wall 15 is connected in one piece to a base part 13 which extends from one narrow side of the center base 14 to the other narrow side and is arranged on the rear side of the switching device 10.

In der Mitte zwischen beiden Schmalseiten besitzt die Zwischenwand 15 einen Spalt 46, der sich vom Bodenteil 13 bis zur Frontseite erstreckt und zur Aufnahme und Führung eines Schiebers 48 dient, der die als Traverse 51 ausgebildeten beweglichen Kontaktstücke 50 trägt. Zwischen dem Schieber 48 und dem Bodenteil 13 ist eine Schraubendruckfeder 49 angeordnet, die den Schieber 48 nach oben beaufschlagt, wo er sich über einen Verbin­dungshebel 31 am Schaltgriff 32 abstützt. Je nach Schwenkstellung des Schaltgriffs 32 befindet sich der Schieber 48 entweder in der in Figur 2 gezeigten oberen oder in einer unteren Position. Abhängig von der ge­wünschten Schaltfunktion und dementsprechend abhängig von der Lage der festen Kontaktstücke 52 sind die Schaltkontakte dann jeweils geöffnet oder geschlossen.In the middle between the two narrow sides, the intermediate wall 15 has a gap 46, which extends from the base part 13 to the front side and serves to receive and guide a slide 48 which carries the movable contact pieces 50 designed as a cross member 51. Between the slider 48 and the bottom part 13, a helical compression spring 49 is arranged, which acts on the slider 48 upwards, where it is supported on the control handle 32 via a connecting lever 31. Depending on the pivoting position of the control handle 32, the slide 48 is either in the upper position shown in FIG. 2 or in a lower position. Depending on the desired switching function and accordingly on the position of the fixed contact pieces 52, the switching contacts are then respectively opened or closed.

Die festen Kontaktstücke 52 sind ähnlich wie die als Traversen 51 ausgestalteten beweglichen Kontaktstücke 50 durch an einem Flachleiter befestigte Kontaktplättchen 54 gebildet. Dementsprechend sind auch flache Verbin­dungsleiter 57, 61 vorgesehen, die von den Anschlußklem­men 28 zu den Kontaktstellen geführt und jeweils an ih­ren Enden mit einem Kontaktplättchen 54 versehen sind, die 20 jeweils ein festes Kontaktstück 52 bilden.The fixed contact pieces 52 are formed in a similar way to the movable contact pieces 50 designed as traverses 51 by contact plates 54 fastened to a flat conductor. Accordingly, flat connecting conductors 57, 61 are also provided, which lead from the connecting terminals 28 to the contact points and are each provided at their ends with a contact plate 54, which each 20 form a fixed contact piece 52.

Wegen des geringeren Abstandes der Anschlußklemmen 28 auf der oberen Ebene gegenüber dem Abstand der auf der unteren Ebene angeordneten Anschlußklemmen 28 jeweils zu den Kontaktstellen infolge des für die Zugänglichkeit zur Betätigung der Anschlußklemmen erforderlichen Ver­satzes der Anschlußklemmen 28 sind die Verbindungsleiter 57 für die oberen Schalterpole 20, 22 kürzer und anders geformt als die Verbindungsleiter 61 für die unteren Schalterpole 24, 26.Because of the smaller distance between the connecting terminals 28 on the upper level compared to the distance between the connecting terminals 28 arranged on the lower level and the contact points as a result of the offset of the connecting terminals 28 required for accessibility for actuating the connecting terminals, the connecting conductors 57 for the upper switch poles 20 are 22 shorter and differently shaped than the connecting conductors 61 for the lower switch poles 24, 26.

In Figur 6 ist beispielhaft ein Verbindungsleiter 57 für die obere Schaltebene dargestellt, der von der Anschluß­klemme 28 kommend einen nach oben geführten Arm 56 be­sitzt, der für die Schaltfunktion "Öffnen" vorgesehen ist. Gleichzeitig ist ein horizontal geführter Arm 58 vorgeshen, der für die Schaltfunktion "Schließen" vorge­sehen ist. Die Schaltfunktionen werden hierbei jeweils von dem bereits erwähnten Schieber 48 ausgeführt.FIG. 6 shows, by way of example, a connecting conductor 57 for the upper switching level, which, coming from the connecting terminal 28, has an arm 56 which is guided upwards and is intended for the "open" switching function. At the same time, a horizontally guided arm 58 is provided, which is provided for the "closing" switching function. The switching functions are each carried out by the slide 48 already mentioned.

In gleicher Weise ist in Figur 8 ein Verbindungsleiter 61 für die untere Schaltebene dargestellt, dessen einer Arm 60 nach oben geführt ist und dessen zweiter Arm 62 horizontal geführt ist, wobei beide Arme jeweils an ih­rem Ende mit einem Kontaktplättchen 54 versehen sind.In the same way, a connecting conductor 61 for the lower switching level is shown in FIG. 8, one arm 60 of which is guided upward and the second arm 62 of which is guided horizontally, both arms being provided at their ends with a contact plate 54.
