Abstract

A connecting device (ganging device), which is constructed in a U-shape for simultaneous operation of the switching toggles (16, 17), which can rotate about a rotation axis (shaft) (14, 15), of at least two switches (10, 11) which are arranged in a row, has limbs which surround the switching toggles on both sides in the assembled state. Formed regions in the form of tabs (34) are integrally formed on the inner surfaces of the limbs, which tabs (34) engage in corresponding depressions (19, 20) which are arranged on side surfaces (which lie parallel to the rotation axis) of the switching toggles, partially covering the side surfaces in the direction of the rotation axes, and open into an end wall (21, 22), which lies at right angles to the rotation axis, of the switching toggles, it being possible to install the connecting device from only one side of the switch, in the direction of the rotation axes. The connecting device (23) is formed from plastic and has a latching tab (35) which is integrally formed on the inside of the U-shape at the end which is located at the front seen in the installation direction, so that, once the tabs have been installed in the depressions, the connecting device is prevented from being pulled off both in the installation direction and in the direction of the switching toggles (P1), and the latching tab prevents pulling off in the opposite direction to the installation direction. <IMAGE>

Description

Die Erfindung betrifft ein elektrisches Schaltgerät gemäß dem Oberbegriff des Anspruches 1.The invention relates to an electrical switching device according to the preamble of claim 1.

Ein Schaltgerät mit einer U-förmigen Verbindungsvorrichtung der eingangs genannten Art ist aus der DE-AS 25 32 192 bekannt geworden. Mit dieser Vorrichtung werden die Schaltknebel mehrerer Schalter zur Bildung z. B. eines mehrpoligen Schaltgerätes miteinander verbunden. Sie ist aus gestanztem und U-förmig gebogenem Blech gebildet und besitzt an den Innenwänden der Schenkel Ausklinkungen, die in entsprechende Vertiefungen am Schaltknebel eingreifen. Dadurch kann die Vorrichtung in einer Richtung auf die in einer Reihe hintereinander liegenden Schaltknebel aufgeschoben werden; zur Verhinderung eines Abziehens entgegen der Montagerichtung ist eine Zunge am Steg der U-Form vorgesehen, die im montierten Zustand gegen die benachbarte Stirnfläche des benachbarten Schaltknebels abgebogen wird. Insbesondere die Umbiegung der Zunge bringt Bruchgefahr mit sich, da das Blech mit relativ hoher Kraft mittels eines Stanz- oder Biegewerkzeugs am montierten Schaltgerät umzubiegen ist. Darüberhinaus ist die Betätigungsfläche zur Betätigung der Schaltknebel gegenüber der Schaltknebelhöhe nur um den Betrag der Blechdicke, ca. 0,5 mm vergrößert, so daß die Handhabung relativ schwer ist.A switching device with a U-shaped connecting device of the type mentioned is known from DE-AS 25 32 192. With this device, the switch toggle of several switches to form z. B. a multi-pole switching device connected to each other. It is formed from stamped and U-shaped sheet metal and has notches on the inner walls of the legs, which engage in corresponding recesses on the shift knob. As a result, the device can be pushed in one direction onto the switching toggles lying in a row; To prevent pulling against the assembly direction, a tongue is provided on the web of the U-shape, which is bent against the adjacent end face of the adjacent switching knob in the assembled state. In particular, the bending of the tongue entails a risk of breakage, since the sheet metal has to be bent with a relatively high force by means of a punching or bending tool on the assembled switching device. In addition, the actuating surface for actuating the switch toggle is only increased by the amount of the sheet thickness, about 0.5 mm, compared to the switch toggle height, so that handling is relatively difficult.

Aufgabe der Erfindung ist es, ein Schaltgerät der eingangs genannten Art mit einer U-förmigen Verbindungsvorrichtung zu schaffen, bei dem die Verbindungsvorrichtung einfacher und unter Vermeidung einer Bruchgefahr zu montieren ist und bei der die Betätigungsfläche auf einfache Weise erhöht werden kann.The object of the invention is to provide a switching device of the type mentioned at the outset with a U-shaped connecting device in which the connecting device is easier to assemble and avoid the risk of breakage and in which the actuating area can be increased in a simple manner.

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

Im Gegensatz zu der Verbindungsvorrichtung des Schaltgerätes nach der DE-AS 25 32 192 ist die erfindungsgemäße Verbindungsvorrichtung aus Kunststoff gebildet. Hierdurch ist es möglich, anstatt eines umzubiegenden Lappens als Mittel zur Verhinderung des Abziehens in die der Montagerichtung entgegengesetzten Richtung eine an der Innenseite der U-Form angeformte Nase vorzusehen, die beim Montieren über den benachbarten Schaltknebel hinüberrutscht und im montierten Zustand hinter den Schaltknebel verrastet ist. Damit kann die Verbindungsvorrichtung weder in Richtung der Drehachsen der Schaltknebel noch in Richtung der Schaltknebel senkrecht zu ihren Drehachsen abgezogen werden. Eine Verschiebung der Verbindungsvorrichtung in eine Richtung wird durch die Zusammenwirkung der Ausformungen am Schaltknebel und der Ausformungen an den Innenflächen der U-förmigen Verbindungsvorrichtung verhindert, wobei diese auch ein Abziehen senkrecht zu den Drehachsen verhindern; ein Abziehen in die entgegengesetzte Richtung wird durch die Nase verhindert.In contrast to the connecting device of the switching device according to DE-AS 25 32 192, the connecting device according to the invention is made of plastic. This makes it possible to provide a nose formed on the inside of the U-shape instead of a flap to be bent as a means of preventing pulling off in the direction opposite to the assembly direction, which nose slides over the adjacent shift knob during assembly and is locked behind the shift knob in the assembled state . Thus, the connecting device can be pulled off neither in the direction of the axes of rotation of the shift knob nor in the direction of the shift knob perpendicular to their axes of rotation. A displacement of the connecting device in one direction is prevented by the interaction of the formations on the switching knob and the formations on the inner surfaces of the U-shaped connecting device, these also preventing pulling off perpendicular to the axes of rotation; peeling in the opposite direction is prevented by the nose.

Eine vorteilhafte Ausgestaltung der Erfindung kann dahin gehen, daß die Verbindungsvorrichtung in ihrem mittleren Bereich zur Verstärkung und besseren Handhabbarkeit einen Bereich größerer Höhe aufweist. Zu diesem Zweck besitzt die Außenfläche des Steges der U-Form einen mittig angeordneten, etwa dachförmigen Aufsatz.An advantageous embodiment of the invention can be such that the connecting device has an area of greater height in its central area for reinforcement and better manageability. For this purpose, the outer surface of the web of the U-shape has a centrally arranged, approximately roof-shaped attachment.

In zweckmäßiger Weise ist die Nase an der Innenfläche des Steges angeformt. Sie wird dadurch gebildet, daß im Steg eine durch vom freien Ende der Vorrichtung ausgehende Stütze gebildete Zunge vorgesehen ist, an der die Nase angeformt ist.The nose is expediently molded onto the inner surface of the web. It is formed in that a tongue is provided in the web, formed by a support extending from the free end of the device, on which the nose is molded.

Weitere vorteilhafte Ausgestaltungen und Verbesserungen sind den weiteren Unteransprüchen zu entnehmen.Further advantageous refinements and improvements can be found in the further subclaims.

Anhand der Zeichnung, in der ein Ausführungsbeispiel der Erfindung dargestellt ist, sollen die Erfindung sowie weitere vorteilhafte Ausgestaltungen und Verbesserungen der Erfindung und weitere Vorteile näher erläutert und beschrieben werden.On the basis of the drawing, in which an embodiment of the invention is shown, the invention as well as further advantageous refinements and improvements of the invention and further advantages are to be explained and described in more detail.

Es sei nun Bezug genommen auf die Figur 5. Man erkennt zwei nebeneinander aufgereihte Leitungsschutzschalter 10 und 11 in Ansicht auf die Schmalseiten. Aus einer Vertiefung 12 und 13 ragen um Drehachsen 14 und 15 schwenkbare Schaltknebel 16 und 17 heraus, von denen der Schaltknebel 16 des Schalters 10 vollständig und der Schaltknebel 17 des Schalters 11 nur teilweise sichtbar ist. Die DrehachsenReference is now made to FIG. 5. Two line circuit breakers 10 and 11 are lined up next to one another in a view of the narrow sides. From a recess 12 and 13, pivoting toggles 16 and 17 protrude about axes of rotation 14 and 15, of which the toggle 16 of the switch 10 is completely visible and the toggle 17 of the switch 11 is only partially visible. The axes of rotation

14 und 15 der beiden Schaltknebel fluchten miteinander. Jeder Schaltknebel 16, 17 besitzt auf seinen parallel zu den Drehachsen 14 und 15 verlaufenden Seitenflächen - bei dem Schaltknebel 16 ist lediglich die Seitenfläche 18 sichtbar - Vertiefungen 19 und 20; die Vertiefung 20 ist nicht sichtbar. Diese Vertiefungen 19 und 20 verlaufen parallel zu den Drehachsen 14 und 15 und überdecken lediglich den halben Bereich der Seitenfläche 18, so daß sie in die gleiche Stirnfläche 21 und 22 jedes Schaltknebels 16, 17 einmünden. Die Vertiefungen 19 und 20 können, wie oben angedeutet, auf beiden Seitenflächen der Schaltknebel 16 und 17 angeordnet sein; sie können sich natürlich auch nur auf einer Seite, beispielsweise der dem Betrachter zugewandten Seitenfläche 18 der Schaltknebel 16 und 17 befinden. Bei den in der Figur 5 dargestellten Schaltern 10 und 11 sind die Vertiefungen 19 und 20 auf beiden Seitenflächen der Schaltknebel 16, 17 vorgesehen.14 and 15 of the two control knobs are aligned. Each switching knob 16, 17 has on its side surfaces running parallel to the axes of rotation 14 and 15 - in the switching knob 16 only the side surface 18 is visible - depressions 19 and 20; the recess 20 is not visible. These recesses 19 and 20 run parallel to the axes of rotation 14 and 15 and only cover half the area of the side surface 18, so that they open into the same end surface 21 and 22 of each switching knob 16, 17. The depressions 19 and 20 can, as indicated above, be arranged on both side surfaces of the switching knobs 16 and 17; they can of course also be located on only one side, for example the side surface 18 of the switching knobs 16 and 17 facing the viewer. In the switches 10 and 11 shown in FIG. 5, the depressions 19 and 20 are provided on both side surfaces of the switching knobs 16, 17.

Die beiden Schaltknebel 16 und 17 sind von einer Verbindungsvorrichtung 23 überdeckt, die anhand der Figuren 1 bis 4 näher beschrieben werden soll.The two switching knobs 16 and 17 are covered by a connecting device 23, which will be described in more detail with reference to FIGS. 1 to 4.

Die Verbindungsvorrichtung 23 besitzt eine U-Form mit einem Steg 24 und zwei daran angeformten Schenkeln 25, 26, die einen spitzen Winkel miteinander einschließen, der in Richtung der offenen Seite der U-Form geöffnet ist. Der Steg 24 besitzt etwa in der Mitte der Verbindungsvorrichtung 23 einen Aufsatz 27, der eine Dachform bildet und der zur Vergrößerung der Höhe H der Verbindungsvorrichtung 23 dient. Die vergrößerte Höhe ist mit H1 bezeichnet. An dem in der Figur 1 bzw. 2 links befindlichen Ende besitzt der Steg 24 zwei parallele Schlitze 28 und 29, die eine Zunge 30 zwischen sich nehmen, an deren innerem, der U-Form zugewandten Ende eine in der Figur 1 strichliert dargestellte Rastnase 35 angeformt ist. Die Schlitze 28 und 29 befinden sich so am Steg 24, daß sie direkt an den Innenseiten der Schenkel 25 uns 26 anschließen.The connecting device 23 has a U-shape with a web 24 and two legs 25, 26 formed thereon, which form an acute angle with one another, which is open in the direction of the open side of the U-shape. The web 24 has an attachment 27 approximately in the middle of the connecting device 23, which forms a roof shape and which serves to increase the height H of the connecting device 23. The increased height is designated H 1 . At the end located on the left in FIGS. 1 and 2, the web 24 has two parallel slots 28 and 29, which take a tongue 30 between them is molded. The slots 28 and 29 are so on the web 24 that they connect directly to the inside of the legs 25 and 26.

In einem dem Abstand zweier Schaltknebel 16 und 17 zweier nebeneinander aufgereihter Leitungsschutzschalter 10 und 11 entsprechenden Abstand sind an der Innenseite der Schenkel 25 und 26 senkrecht zu der Schenkelfläche vorspringende, sich jeweils gegenüberliegende Nasenpaare 31 und 32 bzw. 33 und 34 vorgesehen, die so bemessen sind, daß sie in die Vertiefungen 19 und 20 hineinpassen. Wie insbesondere aus der Figur 5 ersichtlich, paßt die Nase 34 exakt in die Vertiefung 20, wobei die Nase 34 an der etwa in der Mitte befindlichen Endwand 20a der Vertiefung 20 zum Anschlag gelangen kann. Eine entsprechende Endwand besitzt auch die Vertiefung 19; sie ist mit der Bezugsziffer 19a bezeichnet.At a distance corresponding to the distance between two switching toggles 16 and 17 of two line circuit breakers 10 and 11 lined up next to one another, on the inside of the legs 25 and 26 projecting, opposite nose pairs 31 and 32 or 33 and 34 are provided, perpendicular to the leg surface, and dimensioned in this way are that they fit into the recesses 19 and 20. As can be seen in particular from FIG. 5, the nose 34 fits exactly into the depression 20, the nose 34 being able to come to a stop on the end wall 20a of the depression 20 which is approximately in the middle. A corresponding end wall also has the recess 19; it is designated by the reference number 19a.

Um die Verbindungsvorrichtung zu montieren, werden die beiden Schaltknebel 16 und 17 miteinander fluchtend gestellt, beispielsweise in Einschalt- oder Ausschaltstellung. Sodann wird die Verbindungsvorrichtung 23 senkrecht zu den Drehachsen 14, 15 so über die Schaltknebel 16 und 17 geschoben, daß die Nasen 31, 32; 33, 34 vor den Vertiefungen 19 und 20 zu liegen kommen. Dabei besteht die Möglichkeit, daß die Rastnase 35 auf der Stirnkante des Schaltknebels aufliegt, wobei die Zunge 30 verformt ist. Sodann wird die Verbindungsvorrichtung 23 nach links, in Pfeilrichtung P, verschoben, so daß die Nasen 31, 32; 33, 34 in die jeweiligen Vertiefungen 19, 20 eingreifen, und zwar soweit, bis die Nasen 31, 32 bzw. 33, 34 an den Stirnflächen 19a bzw. 20a der Vertiefungen 19 und 20 zum Anschlag kommen. Wenn dies der Fall ist, wird die Nase 32 hinter die linke Stirnfläche 21a des Schaltknebels 16 greifen und auf diese Weise dahinter verrasten, so daß die Verbindungsvorrichtung 23 entgegen der Pfeilrichtung P nicht mehr von den Schaltknebeln 16, 17 abgezogen werden kann. Die Stirnflächen 19a und 20a verhindern eine weitere Verschiebung der Verbindungsvorrichtungen in Pfeilrichtung P und dadurch, daß die Nasen 31 bis 34 in die Vertiefungen 19 und 20 eingreifen, wird auch ein Abziehen der Verbindungsvorrichtung 23 in Richtung der Schaltknebel 16, 17, Pfeilrichtung P1, verhindert.In order to assemble the connecting device, the two switching knobs 16 and 17 are placed in alignment with one another, for example in the on or off position. Then the connecting device 23 is pushed perpendicular to the axes of rotation 14, 15 over the switching knob 16 and 17 so that the lugs 31, 32; 33, 34 come to rest in front of the recesses 19 and 20. There is the possibility that the locking lug 35 rests on the front edge of the shift knob, the tongue 30 being deformed. Then the connecting device 23 is moved to the left, in the direction of arrow P, so that the lugs 31, 32; 33, 34 engage in the respective recesses 19, 20, namely until the lugs 31, 32 and 33, 34 come to abut against the end faces 19a and 20a of the recesses 19 and 20. If this is the case, the nose 32 will grip behind the left end face 21a of the switching knob 16 and in this way latch behind it, so that the connecting device 23 can no longer be pulled off the switching knobs 16, 17 in the opposite direction of the arrow P. The end faces 19a and 20a prevent further displacement of the connecting devices in the direction of the arrow P, and the fact that the lugs 31 to 34 engage in the recesses 19 and 20 also means that the connecting device 23 is pulled off in the direction of the switching knobs 16, 17, arrow direction P 1 , prevented.

In der Figur 4 bzw. 2 sind Durchbrüche 40, 41 bzw. 42, 43 zu sehen, die sich genau über den Nasen 31 bis 34 befinden. Diese Stege haben lediglich werkzeugtechnische Gründe. Zu einer gewissen Materialersparnis tragen sie selbstverständlich auch bei.Openings 40, 41 and 42, 43 can be seen in FIGS. 4 and 2, respectively, which are located exactly above the lugs 31 to 34. These webs have only tool-technical reasons. Of course, they also contribute to a certain saving in material.

Mit der erfindungsgemäßen Verbindungsvorrichtung ist eine einfache Montage möglich und aufgrund der Herstellung durch Spritzgießen ist auch eine einfachere Herstellung der Verbindungsvorrichtung 23 möglich. Der mittlere Ansatz bzw. Aufsatz 27 dient sowohl zur Vergrößerung der Betätigungsfläche als auch zur Erhöhung der Steifigkeit der Verbindungsvorrichtung 23.Simple assembly is possible with the connecting device according to the invention, and simpler production of the connecting device 23 is also possible due to the production by injection molding. The middle approach or attachment 27 serves both to enlarge the actuating area and to increase the rigidity of the connecting device 23.

Die Figuren 1 bis 5 zeigen eine Verbindungsvorrichtung 23, mit der lediglich zwei Schaltknebel 16 und 17 zweier nebeneinander aufgereihter Leitungsschutzschalter 10, 11 verbunden werden, so daß hierdurch ein zweipoliger Leitungsschutzschalter gebildet wird. Es ist selbstverständlich möglich, die Verbindungsvorrichtung so auszugestalten, daß drei oder vier nebeneinander liegende Leitungsschutzschalter miteinander verbunden werden können; zu diesem Zweck sind drei bzw. vier Nasenpaare vorgesehen, die den Nasen 31/32, 33/34... entsprechen. Dadurch wird die Verbindungsvorrichtung lediglich länger.FIGS. 1 to 5 show a connecting device 23, with which only two switching knobs 16 and 17 of two line circuit breakers 10, 11 are lined up next to one another, so that a two-pole line circuit breaker is thereby formed. It is of course possible to design the connection device so that three or four adjacent circuit breakers can be connected to each other; For this purpose, three or four pairs of noses are provided, which correspond to the noses 31/32, 33/34 ... This only makes the connecting device longer.

Selbstverständlich kann die Erfindung auch bei allen anderen Schaltgeräten angewendet werden, die je einen Schaltknebel aufweisen und zu mehreren zur Bildung einer Mehrpoligkeit nebeneinander aufgereiht werden.Of course, the invention can also be applied to all other switching devices which each have a switching knob and are lined up in a row to form a multipole.

Die Erfindung ist auch dann verwirklicht, wenn an den Seitenflächen der Schaltknebel vorspringende Nasen und an den Innenflächen der Schenkel der Verbindungsvorrichtung an die Nasen angepaßte Vertiefungen vorgesehen sind.The invention is also realized if protruding lugs are provided on the side surfaces of the switching toggles and recesses adapted to the lugs are provided on the inner surfaces of the legs of the connecting device.
