The housing 11 of the arc extinguishing device is in a housing of the not shown in detail Low voltage switch installed. The shift shaft unit 9 serves to establish an electrical connection between the two Produce current conductors 16.

    Die Schaltwelleneinheit 9 besteht im wesentlichen aus einem zylindrisch ausgebildeten Schaltwellenkörper 2, an dem ein S-förmiger Kontakthebel 3 mittels einer in diesem Körper eingebauten Lagerachse 5 drehbar abgestützt ist. Die ganze Schaltwelleneinheit 9 ist in einem nicht dargestellten Aufnahmeabschnitt des Gehäuses 11 drehbar gelagert, wobei die besondere Art dieser Lagerung im Rahmen der nachfolgenden Darstellung des konstruktiven Aufbaus der Schaltwelleneinheit im einzelnen erläutert wird.The shift shaft unit 9 consists essentially of a Cylindrical switching shaft body 2, on which an S-shaped Contact lever 3 by means of one in this body built-in bearing axis 5 is rotatably supported. The whole Switch shaft unit 9 is not shown in one Receiving section of the housing 11 rotatably supported, the special type of this storage within the scope of the following Representation of the design of the shift shaft unit in the individual is explained.

    Die Schaltwelleneinheit 9 ist mittels eines Gelenks 10 betätigbar, um den in Fig. 1 gezeigten eingeschalteten Zustand oder den in Fig. 2 gezeigten ausgeschalteten Zustand des Schalters zu erreichen.The shift shaft unit 9 is by means of a joint 10 can be actuated to the switched-on state shown in FIG. 1 or the switched-off state of the To reach the switch.

    Wie der Fig. 3a im einzelnen zu entnehmen ist, besteht die Schaltwelleneinheit 9 aus einem Schaltwellenkörper 2, der rotationssymmetrisch, in etwa zylindrisch, ausgebildet ist. Die Achse des zylindrischen Schaltwellenkörpers 2 fällt mit der geometrischen Achse der Lagerachse 5 zusammen, an dem der Kontakthebel 3 schwenkbar gelagert ist. Der Kontakthebel 3 ist in einer sich senkrecht zur Achse des Schaltwellenkörpers 2 erstreckenden Aussparung 2e aufgenommen, die den Schaltwellenkörper 2 diametral durchsetzt.As can be seen in Fig. 3a in detail, there is Shift shaft unit 9 from a shift shaft body 2, the is rotationally symmetrical, approximately cylindrical. The Axis of the cylindrical shift shaft body 2 coincides with the geometric axis of the bearing axis 5 together, on which the Contact lever 3 is pivotally mounted. The contact lever 3 is in a direction perpendicular to the axis of the selector shaft body 2 extending recess 2e added to the Switch shaft body 2 penetrated diametrically.

    Auf beiden Stirnseiten des zylindrischen Schaltwellenkörpers 2 sind Vertiefungen 2c vorgesehen, die sich diametral und parallel zueinander erstrecken und kanalförmig ausgebildet sind. An den Enden der kanalförmigen Vertiefungen 2c sind jeweils in der Wandung zwischen der mittigen Aussparung 2e und des Bodenabschnitts der jeweiligen Vertiefung 2c U-förmige Schlitze 2d eingearbeitet, die zur Aufnahme von Stiften.6 vorgesehen sind. Auf jedem Stift 6 ist in etwa mittig eine Rolle 6a drehbar gelagert, die in der Aussparung 2e gleitend aufgenommen ist. In den kanalförmigen Vertiefungen 2c sind Feder 7 aufgenommen, die beidseitig an den Spannstiftenden auf jeder Stirnseite des Schaltwellenkörpers 2 eingehängt sind. Die Länge der Schlitze 2d ist dabei im Vergleich zu der Breite des mittigen Lagerabschnitts des S-förmigen Kontakthebels 3 so bemessen, daß unabhängig vom Betriebszustand des Schalters die Stifte 6 unter keinen Umständen bis zum Anschlag an den Böden der U-förmigen Schlitze 2d zusammengezogen werden können. Eine Verdrehung des Schaltwellenkörpers 2 führt dazu, daß die Rollen 6a der Stifte 6 auf den jeweils anliegenden Scheiteln des S-förmigen Kontakthebels 3 abrollen und dabei entgegen der die Spannstifte 6 zusammenziehenden Kraft der Feder 7 in den Schlitzen 2d auseinandergedrückt werden, um dadurch eine ständige Spannkraft auf den Kontakthebel 3 entgegen dem Uhrzeigersinn auszuüben.On both ends of the cylindrical shift shaft body 2 recesses 2c are provided, which are diametrical and parallel extend to each other and are channel-shaped. To the Ends of the channel-shaped depressions 2c are each in the Wall between the central recess 2e and Bottom portion of the respective recess 2c U-shaped slots 2d incorporated, which is intended to hold pins. 6 are. On each pin 6 there is a roller 6a approximately in the center rotatably mounted, which slidably received in the recess 2e is. Spring 7 is located in the channel-shaped recesses 2c added on both sides at the spring pin ends on each Front of the switching shaft body 2 are hooked. The length the slots 2d is compared to the width of the central bearing section of the S-shaped contact lever 3 so dimensioned that regardless of the operating state of the switch Under no circumstances pins 6 up to the stop on the floors the U-shaped slots 2d can be contracted. A Rotation of the shift shaft body 2 causes the rollers 6a of the pins 6 on the respective adjacent vertices of the S-shaped Roll the contact lever 3 while doing it against the Spring pins 6 contracting force of the spring 7 in the Slits 2d are pushed apart to form one constant clamping force on the contact lever 3 against the Exercise clockwise.

    Der Schaltwellenkörper 2 weist des weiteren eine Aufnahmeöffnung 2b auf, in welcher ein stabförmiger Stift 1 aufgenommen ist. Diametral entgegengesetzt zu der Aufnahmeöffnung 2b sind auf beiden Stirnseiten des Schaltwellenkörpers 2 U-förmige Aussparungen 2a eingearbeitet. The switching shaft body 2 also has a receiving opening 2b, in which a rod-shaped pin 1 is received. Diametrically opposite to the receiving opening 2b are on two end faces of the shift shaft body 2 U-shaped Cutouts 2a incorporated.

    Auf beiden Seiten des zylindrischen Schaltwellenkörpers 2 sind Kappen 8 vorgesehen. Jede Kappe 8 hat einen umfangseitigen, zylindrischen Kragenabschnitt 8e und ist an ihrer Innenseite mit einem Paar in etwa diametral verlaufenden Verstärkungsrippen 8c sowie einem unabhängig von diesen ausgebildeten U-förmigen Rippenabschnitt 8a versehen.

Der zylindrische Abschnitt 8b befindet sich diametral entgegengesetzt zu dem hervorstehenden U-förmigen Rippenabschnitt 8a und hat einen Außendurchmesser, der in etwa dem Innendurchmesser der im Schaltwellenkörper 2 ausgebildeten Aufnahmeöffnung 2b entspricht. Die den Mittelpunkt des zylindrischen Abschnitts 8b mit dem Mittelpunkt des U-förmigen Rippenabschnitts 8a verbindende Linie schließt mit der zwischen den Rippen 8c hypothetisch gezogenen Diametrallinie den gleichen Winkel, wie der Winkel zwischen der die Aussparung 2a mit der Aufnahmeöffnung 2b verbindende Linie und der Mittellinie der kanalförmigen Vertiefung 2c. Dieser Winkel liegt grundsätzlich zwischen 20° und 70°, vorzugsweise bei ca. 65°.The cap 8 also has an opening through it extending cylindrical on the inside of the cap Section 8b is formed. The cylindrical section 8b is diametrically opposite to the protruding one U-shaped rib portion 8a and has an outer diameter, which is approximately the inside diameter of the one in the selector shaft body 2 trained receiving opening 2b corresponds.

Auf der stirnseitigen Außenfläche einer jeden Kappe sind zwei diametral entgegengesetzt zueinander liegende Öffnungen 8g ausgebildet, die zur Druckentlastung des Schaltwellenkörpers 2 dienen. Eine der Kappen 8 weist an ihrem Kragenabschnitt 8e einen vorspringenden Abschnitt 8h auf, der gleichzeitig zur Markierung der richtigen Montagestellung der Kappe und umfangseitigen Abdeckung der Schlitze 2d und der Rollen 6a im Schaltwellenkörper 2 dient.Each cap 8 is on its outside with a journal 8f provided for the axial mounting of the shift shaft unit 9 in the not shown receiving portion of the switch housing 11 serves. On the face of each cap are two diametrically opposed to each other Openings 8g formed to relieve the pressure on the Switch shaft body 2 serve. One of the caps 8 has on her Collar section 8e has a projecting section 8h which at the same time to mark the correct mounting position of the Cap and circumferential cover of the slots 2d and Rollers 6a in the shift shaft body 2 is used.

    Bei der Montage der Schaltwelleneinheit 9 wird zunächst der Kontakthebel 3 in die Aussparung 2e des Schaltwellenkörpers 2 so eingepaßt, daß der als Gelenkachse dienende Stift 5 von außen durch den Schaltwellenkörper 2 und eine nicht im einzelnen dargestellte Lageröffnung des Kontakthebels 3 durchgeschoben werden kann. Daraufhin werden die Stifte 6 in die Schlitze 2d eingesetzt und die Feder 7 auf beide Seiten des Schaltwellenkörpers an den Stiftenden unter leichtes Auseinanderziehen der Feder eingehängt. Anschließend werden die zwei Kappen 8 zunächst soweit auf beiden Stirnseiten des Schaltwellenkörpers 2 zusammengedrückt, bis der auf der Innenseiten der Kappen vorgesehene U-förmige Rippenabschnitt 8a, die Rippen 8c und der zylinderförmige Abschnitt 8b entsprechend in die U-förmige Aussparung 2a, die kanalförmige Vertiefung 2c und die Aufnahmeöffnung 2b eingepaßt werden. Die Kappen 8 sind vorzugsweise aus Kunststoff gefertigt, so daß die auf der Innenseite der Kappen vorgesehenen erhabenen Abschnitte 8a, 8c und 8a unter leichtem Preßdruck auf beiden Seiten des Schaltwellenkörpers 2 eingesetzt werden können und daher keine zusätzliche Mittel zur Befestigung dieser Kappen am Schaltwellenkörper erforderlich sind.When assembling the shift shaft unit 9, the Contact lever 3 in the recess 2e of the shift shaft body 2 so fitted that the pin 5 serving as the hinge axis from the outside through the switching shaft body 2 and one not in detail pushed through the illustrated bearing opening of the contact lever 3 can be. The pins 6 are then inserted into the slots 2d used and the spring 7 on both sides of the Switch shaft body at the pin ends under light Pull the spring apart. Then the two caps 8 initially so far on both ends of the Switch shaft body 2 compressed until the on the U-shaped rib section 8a provided on the inside of the caps, the ribs 8c and the cylindrical portion 8b accordingly into the U-shaped recess 2a, the channel-shaped recess 2c and the receiving opening 2b are fitted. The caps 8 are preferably made of plastic, so that on the Raised portions 8a, 8c provided on the inside of the caps and 8a under slight pressure on both sides of the Switch shaft body 2 can be used and therefore none additional means for attaching these caps to the Switch shaft body are required.

    Die auf diese Weise zusammengebaute Schaltwelleneinheit 9 wird dann in das Gehäuse 11 der Lichtbogenlöscheinrichtung in einem in Fig. 1 nicht im einzelnen gezeigten Aufnahmeabschnitt so angeordnet, daß die sich auf beiden Seiten der Schaltwelleneinheit axial erstreckenden Lagerzapfen 8f in entsprechende Konturen mit Gleitlagerabschnitten des Aufnahmeabschnitts aufgenommen werden können. Daraufhin wird das in Fig. 1 gezeigte Gelenk 10 auf einer Außenseite des Gehäuses 11 so angebracht, so daß der stabförmige Stift 1 in eine am unteren Ende des Gelenks 10 ausgebildete Öse und eine mit der Öse fluchtend ausgerichtete Öffnung eines der zylindrischen Abschnitte 8b der Kappen 8 eingesetzt werden kann.The shift shaft unit 9 assembled in this way becomes then in the housing 11 of the arc extinguishing device in one 1 not shown in detail in the receiving section arranged that the on both sides of the Shift shaft unit axially extending bearing pin 8f in corresponding contours with plain bearing sections of the Recording section can be included.

    Die Figuren 4a und 4b zeigen eine weitere Ausführungsform der erfindungsgemäßen Schaltwelleneinheit 9. Diese Ausführungsform der Schaltwelleneinheit unterscheidet sich von der ersten in den Figuren 3a und 3b gezeigten Ausführungsform im wesentlichen durch die andersartige Ausbildung der Stirnseiten des Schaltwellenkörpers und der Kappen.Figures 4a and 4b show a further embodiment of the switching shaft unit 9 according to the invention. This embodiment the shift shaft unit differs from the first in the Figures 3a and 3b embodiment shown essentially due to the different design of the end faces of the Switch shaft body and the caps.

    Der in den Figuren 4a und 4b dargestellte Schaltwellenkörper 22 hat eine sich senkrecht zur Achse des Schaltwellenkörpers erstreckende Aussparung 22e, in der der Kontakthebel 23 mit den Kontaktelementen 24 aufgenommen und auf einem Stift 25 gelagert ist. In der gleichen Art und Weise wie bei der ersten Ausführungsform gelangen die erweiterten zylindrischen Abschnitte 26a der Stifte 26 in Anlage mit den Scheitelflächen des S-förmigen Kontakthebels 23, wie das in der Darstellung der Fig. 1 angedeutet ist, um bei einer Verdrehung des Schaltwellenkörpers 22 entgegen dem Uhrzeigersinn eine elastische Anpreßkraft auf den Kontakthebel in seiner Schließstellung auszuüben. Dieser Mechanismus wurde bereits bei der ersten Ausführungsform erläutert.The selector shaft body 22 shown in FIGS. 4a and 4b has a perpendicular to the axis of the shift shaft body extending recess 22e in which the contact lever 23 with the Contact elements 24 added and stored on a pin 25 is. In the same way as the first Embodiment arrive the extended cylindrical Portions 26a of pins 26 abut the apex surfaces of the S-shaped contact lever 23, as in the illustration of the Fig. 1 is indicated to a rotation of the Switch shaft body 22 counterclockwise one elastic contact pressure on the contact lever in its Exercise closed position. This mechanism was already in use of the first embodiment.

    Auf einer jeden Stirnseite des Schaltwellenkörpers 22 sind jeweils 2 in etwa rechteckige Vorsprünge 22a, 22b diametral zueinander entgegengesetzt ausgebildet. Die auf beiden Stirnseiten des Schaltwellenkörpers 22 ausgebildeten Vorsprünge 22b bilden die Ausläufe eines im Schaltwellenkörper 22 zur Aufnahme eines stabförmigen Stiftes 21 vorgesehenen Bohrungsabschnitts, während in den diametral dazu entgegengesetzt ausgebildeten Vorsprüngen 22a lediglich Öffnungen 22g ausgebildet sind. Zwischen den Vorsprüngen 22a und 22b ist eine diametral verlaufende kanalförmige Vertiefung 22c zur Aufnahme der Feder 27 ausgebildet. Entlang der zueinander gegenüberliegenden Seiten der Vorsprünge 22a, 22b sind in den Stirnseiten des Schaltwellenkörpers 22 schlitzförmige Vertiefungen 22f ausgebildet.On each end face of the switching shaft body 22 are 2 each approximately rectangular projections 22a, 22b diametrically opposite to each other. The one on both End faces of the switching shaft body 22 formed projections 22b form the outlets of one in the switching shaft body 22 Provided a rod-shaped pin 21 provided Bore section, while in the diametrical to this opposite projections 22a only Openings 22g are formed. Between the projections 22a and 22b is a diametrically extending channel-shaped depression 22c designed to receive the spring 27. Along the each other opposite sides of the protrusions 22a, 22b are shown in FIGS End faces of the shift shaft body 22 slit-shaped Wells 22f formed.

    Auf beiden Seiten des Schaltwellenkörpers 22 sind aus flachem Material ausgebildete tellerförmige Kappen 28 vorgesehen. Diese Kappen haben eine im wesentlichen flache Scheibenform mit diametral zueinander entgegengesetzt ausgebildeten Ausschnitte 28a, 28b, die beim Aufsetzen der Kappen dazu geeignet sind, die an den Stirnseiten des Schaltwellenkörpers 22 ausgebildeten Vorsprünge 22a, 22b aufzunehmen. Die U-förmigen Ausschnitte 28a, 28b haben in ihrem Bodenbereich zu der Montageseite der Kappen 28 hin abgewinkelten Abschnitte 28c, die ihrer Länge nach der Breite der Ausschnitte 28a, 28b entsprechenden, zur festen Anbringung der Kappen an die Stirnseiten des Schaltwellenkörpers 22 in die schlitzförmigen Vertiefungen 22f steckbar sind und gleichzeitig zur Erhöhung der Kriech- und Luftstrecken im Schalter dienen.On both sides of the shift shaft body 22 are made of flat Material-shaped plate-shaped caps 28 are provided. This Caps have an essentially flat disc shape with Cutouts diametrically opposed to each other 28a, 28b, which are suitable when fitting the caps, the formed on the end faces of the switching shaft body 22 To receive projections 22a, 22b. The U-shaped cutouts 28a, 28b have in their bottom area to the mounting side of the caps 28 angled sections 28c, the length of the Width of the cutouts 28a, 28b corresponding to the fixed Attach the caps to the front of the selector shaft body 22 can be inserted into the slot-shaped recesses 22f and at the same time to increase the creepage distances and clearances in the Serve switches.

    In einer jeden Innenfläche der Kappen 28, die jeweils einer der Stirnseiten des Schaltwellenkörpers 22 zugewandt ist, ist außerdem eine X-förmige Vertiefung 28e ausgebildet, die unabhängig von der Stirnseite, an welcher die Kappe anzubringen ist, dazu geeignet ist, einen von der Stirnfläche des Schaltwellenkörpers nach außen hin vorstehenden Abschnitt der Feder 27 aufzunehmen. Diese Ausbildung der Vertiefung 28e gestattet eine Austauschbarkeit der auf beiden Seiten des Schaltwellenkörpers 22 anzubringenden Kappen 28. Wie der Darstellung in Figur 4b zu entnehmen ist, entspricht der Durchmesser der tellerförmigen Kappen 28 dem Durchmesser des zylinderförmigen Schaltwellenkörpers 22, so daß im montierten Zustand die Ränder der Kappen 28 bündig mit der zylindrischen Umfangsfläche des Schaltwellenkörpers 22 ausgerichtet sind.In each inner surface of the caps 28, each one of the End faces of the switching shaft body 22 is facing also formed an X-shaped recess 28e, the regardless of the face to which the cap is to be attached is suitable to one of the end face of the Switch shaft body outwardly projecting section of Take up spring 27. This formation of the recess 28e allows interchangeability of the on both sides of the Switch shaft body 22 to be attached caps 28. How the 4b shows, corresponds to the Diameter of the plate-shaped caps 28 the diameter of the cylindrical switching shaft body 22, so that in the assembled Condition the edges of the caps 28 flush with the cylindrical Circumferential surface of the switching shaft body 22 are aligned.

    Auf der Außenseite einer jeden der Kappen 28 ist ein Lagerzapfen 28f vorgesehen, mittels dessen die Schaltwelleneinheit in einem entsprechend ausgebildeten, in Fig. 1 nicht im einzelnen gezeigten Lagerabschnitt des Gehäuses 11 drehbar gelagert werden kann.On the outside of each of the caps 28 is a journal 28f provided, by means of which the shift shaft unit in one appropriately trained, in Fig. 1 not in detail Bearing section of the housing 11 shown are rotatably supported can.

    Durch die oben im einzelnen dargestellte Ausbildung der Schaltwelleneinheit ist zugleich eine konstruktiv einfach gestaltete Lagerung der Schaltwelleneinheit im Schaltergehäuse und gleichzeitig ein zuverlässiger Schutz der beweglichen Teile im Schaltwellenkörper gegen elektrische Entladungen bei Überschlägen gewährleistet. Außerdem werden die Kriech- und Luftstrecken von dem Kontakthebel 3, den Federn 7 und den Stiften 6 zum stabförmigen Stift 1, der bei einem einpoligen Schalter einen nicht im einzelnen dargestellten Antrieb mit der Schaltwelleneinheit verbindet und bei mehrpoligen Schaltern sowohl diesen Antrieb mit den Schaltwelleneinheiten als auch die Schaltweleneinheiten untereinander verbindet, erhöht. Die Kappen sind so ausgebildet, daß sie eine zuverlässige Verbindung mit dem Schaltwellenkörper gewährleisten. Der Zugang der bei Kurzschlüssen entstehenden Gase zur beweglichen Teile des Schalters und der Schaltwelleneinheit ist dadurch erschwert und eine verbesserte Abschirmung von einer benachbarten Schaltereinheit gewährleistet.Due to the training of the Shift shaft unit is also a structurally simple designed storage of the switching shaft unit in the switch housing and at the same time reliable protection of the moving parts in the switching shaft body against electrical discharges Rollovers guaranteed. In addition, the creep and Clearances from the contact lever 3, the springs 7 and Pins 6 to the rod-shaped pin 1, the one-pole Switch a drive not shown in detail with the Switching shaft unit connects and with multi-pole switches both this drive with the shift shaft units as well Schaltwelen units connecting with each other, increased. The caps are designed so that they have a reliable connection with ensure the switching shaft body. The access of the at Gases generated by short circuits to the moving parts of the Switch and the switching shaft unit is difficult and an improved shielding from an adjacent one Switch unit guaranteed.

    Eine Fehlmontage der Kappen ist unmöglich, weil diese entweder äußerlich voneinander deutlich unterscheidbar sind und daher einer bestimmten Seite des Schaltwellenkörpers zugeordnet werden können, oder eine identische Form aufweisen, dann aber an einer beliebigen Stirnseite des Schaltwellenkörpers anbringbar sind. Incorrect assembly of the caps is impossible because they either are clearly distinguishable from each other and therefore be assigned to a specific side of the shift shaft body can, or have an identical shape, but then on a any end face of the shift shaft body can be attached.

    Bei einer nicht im einzelnen dargestellten Ausführungsform der erfindungsgemäßen Schaltereinheit kann zur Vereinfachung der Herstellung auf die abnehmbaren Kappen verzichtet werden, indem die Spannvorrichtung zwar außerhalb des den Kontakthebel aufnehmenden Bereiches der Aussparung 2e, 22e, jedoch noch geschützt im Inneren des Schaltwellenkörpers untergebracht ist.In an embodiment of the Switch unit according to the invention can be used to simplify the The removable caps can be dispensed with by manufacturing the clamping device outside of the contact lever receiving area of the recess 2e, 22e, however, still is protected inside the switch shaft body.
