Abstract

A connection between levers (3) for a multipole switch moving on a common axis (2) uses a gripper (5) on each lever and a pin (1) passing between each gripper. The grippers are elastically deformable, with an axial slot between two legs into which the pin is pressed. The slot has an undercut to match the profile of the pin, sited near the free end. The outside edges of the legs are chamfered to ease the insertion of the pin into the slot. The pin is thicker over the distance between the grippers than within the slots. This is created by notching the pin.

Description

TECHNISCHES GEBIETTECHNICAL AREA

Bei der Erfindung wird ausgegangen von einer Schalthebelverbindung nach dem Oberbegriff von Patentanspruch 1. Mit einer derartigen Schalthebelverbindung wird eine synchrone Betätigung der Pole eines mehrpoligen Schaltgerätes erreicht. Bevorzugt wird eine solche Schalthebelverbindung in Schaltgeräten, wie insbesondere Leitungs- Fehlerstrom- oder Motorschutzschaltern von Niederspannungsverteilern verwendet. Solche Schalter weisen häufig zwei, drei, vier oder gegebenenfalls sogar mehr als vier gleichartige Pole auf.The invention is based on a shift lever connection according to the preamble of claim 1. With such a shift lever connection, a synchronous actuation of the poles of a multi-pole switching device is achieved. Such a switching lever connection is preferably used in switching devices, such as, in particular, line fault current or motor protection switches of low-voltage distributors. Such switches often have two, three, four or possibly even more than four identical poles.

STAND DER TECHNIKSTATE OF THE ART

Die Erfindung nimmt auf einen Stand der Technik von Schalthebelverbindung Bezug, wie er in dem vom Patentanmelder im Herbst 1989 herausgebenen Handbuch "Innovativ installieren mit smissline" etwa auf S.6 abgebildet ist. Die Schalthebelverbindung nach dem Stand der Technik enthält ein als U-förmig gebogenes Blech ausgebildetes Brückenteil. Dieses Blech ist auf zwei bzw. drei um eine gemeinsame Achse schwenkbare und jeweils als Betätigungsgriff ausgebildete Hebelarme der Schalthebel eines zwei-oder dreipoligen Leitungsschutzschalters gesteckt und bewirkt so die starre Kopplung der Schalthebel und damit eine synchrone Betätigung der einzelnen Schalterpole. Die Herstellung und Montage eines derartigen Brückenteils ist relativ aufwendig.The invention relates to a state of the art of shift lever connection, as is shown in the manual "Innovative installation with smissline" published by the patent applicant in autumn 1989, for example on page 6. The shift lever connection according to the prior art contains a bridge part designed as a U-shaped sheet. This plate is placed on two or three lever arms of the switching lever of a two- or three-pole circuit breaker, which can be pivoted about a common axis and each designed as an actuating handle, and thus causes the rigid coupling of the switching levers and thus a synchronous actuation of the individual switch poles. The manufacture and assembly of such a bridge part is relatively complex.

In DE-A-25 40 745 ist eine Schalthebelverbindung beschrieben, bei der die einzelnen Schalthebel 6 über ein Brückenteil 9 mit angeformten Noppen 8 miteinander verbunden sind. Die Noppen 8 weisen Nasen 15 auf, welche unter Fixierung des Brückenteils 9 in Fenstern 14 der zentral geführten Ausnehmungen 7 der Schalthebel verrastet sind. Eine solche Schalthebelverbindung ist relativ aufwendig, da in jeden Schalthebel die komplizierte, fensterartig erweiterte, zentral geführte Ausnehmung einzubringen ist, und da das Brückenteil mit Noppen und Rastnasen zu versehen ist.DE-A-25 40 745 describes a shift lever connection in which the individual shift levers 6 are connected to one another via a bridge part 9 with molded knobs 8. The knobs 8 have lugs 15, which are locked in place by fixing the bridge part 9 in windows 14 of the centrally guided recesses 7 of the shift lever. Such a shift lever connection is relatively complex since the complicated, window-like, centrally guided recess has to be made in each shift lever, and since the bridge part has to be provided with knobs and locking lugs.

KURZE DARSTELLUNG DER ERFINDUNGSUMMARY OF THE INVENTION

Der Erfindung, wie sie in Patentanspruch 1 angegeben ist, liegt die Aufgabe zugrunde, eine Schalthebelverbindung der eingangs genannten Art anzugeben, die in einfacher und in einer für eine Massenfertigung geeigneten Weise hergestellt werden kann.The invention, as specified in claim 1, is based on the object of specifying a shift lever connection of the type mentioned at the outset which can be produced in a simple manner and in a manner suitable for mass production.

Die Schalthebelverbindung nach der Erfindung zeichnet sich dadurch aus, dass sie durch einfaches Einpressen des Stiftes in die Spreizteile der zu verbindenden Schalthebel äusserst einfach und kostengünstig in einem für Massenfertigung geeigneten Verfahren hergestellt werden kann. Die solchermassen hergestellte Verbindung zeichnet sich durch hohe Festigkeit und eine grosse Betriebssicherheit auch bei starken Beanspruchungen aus. Zudem beeinträchtigt sie weder die Handhabbarkeit der Schalthebelgriffe noch das ästhetische Design des mehrpoligen Schaltgerätes. Darüber hinaus ist diese Schalthebelverbindung nach der Erfindung völlig unabhängig von der Beschaffenheit der Schalthebel und kann durch einfaches Ablängen des Stiftes sehr einfach an unterschiedlich breite Schalterpole sowie an Schaltgeräte mit beliebig vielen Schalterpolen angepasst werden.The shift lever connection according to the invention is characterized in that it can be manufactured extremely simply and inexpensively in a process suitable for mass production by simply pressing the pin into the expansion parts of the shift lever to be connected. The connection produced in this way is characterized by high strength and a high level of operational reliability even under heavy loads. In addition, it does not affect the manageability of the shift lever handles or the aesthetic design of the multi-pole switching device. In addition, this shift lever connection according to the invention is completely independent of the nature of the shift lever and can be easily adapted to switch poles of different widths and to switching devices with any number of switch poles by simply cutting the pin to length.

WEGE ZUR AUSFÜHRUNG DER ERFINDUNGWAYS OF CARRYING OUT THE INVENTION

Die in den Figuren 1 und 2 dargestellte Schalthebelverbindung weist einen Stift 1 und drei um eine gemeinsame Achse 2 des nicht dargestellten Schaltgerätes schwenkbare Schalthebel 3 auf. Die Schalthebel 3 sind aus einem Kunststoff, typischerweise einem Thermoplast, etwa auf der Basis eines Amides, geformt und sind jeweils in einem ebenfalls nicht dargestellten Polgehäuse des Schaltgerätes um die Achse 2 schwenkbar gelagert. Die drei Pole können bei Ausbildung des Schaltgerätes als Leitungsschutzschalter beispielsweise die drei Phasen eines Drehstromsystems sein. Jeder der drei Schalthebel 3 ist zweiarmig ausgebildet und weist jeweils einen mit einem nicht dargestellten Betätigungselement auf eine Kontaktanordnung wirkenden Hebelarm 4 auf sowie einen als Griff 5 ausgebildeten und aus dem Polgehäuse des Schaltgerätes nach aussen geführten weiteren Hebelarm. Um ein synchrones Schalten der in unabhängig voneinander gefertigten Schalterpolen geführten Phasen zu ermöglichen, weisen die Hebelgriffen jeweils ein elastisch verformbares Spreizteil 6 auf und ist in die Spreizteile 6 der parallel zur Schwenkachse 2 ausgerichtete Stift 1 eingepresst.The shift lever connection shown in FIGS. 1 and 2 has a pin 1 and three shift levers 3 pivotable about a common axis 2 of the switching device, not shown. The shift levers 3 are formed from a plastic, typically a thermoplastic, for example based on an amide, and are each pivoted about the axis 2 in a pole housing of the switching device, which is also not shown. When the switching device is designed as a line circuit breaker, the three poles can be, for example, the three phases of a three-phase system. Each of the three shift levers 3 is designed with two arms and each has one with an actuating element, not shown lever arm 4 acting on a contact arrangement and a further lever arm designed as a handle 5 and guided outward from the pole housing of the switching device. In order to enable synchronous switching of the phases which are carried out independently of one another in the switch poles, the lever handles each have an elastically deformable expansion part 6 and the pin 1, which is aligned parallel to the pivot axis 2, is pressed into the expansion parts 6.

Wie aus Fig.2, insbesondere aber aus Fig.3 zu erkennen ist, sind in den Griff 5 als Spreizteil 6 zwei durch einen Schlitz 7 voneinander beabstandete, biegbare Schenkel 8 eingeformt. Der Schlitz 7 weist eine an das Profil des Stifts 1 angepasste Hinterschneidung 9 auf, welche im Bereich der freien Enden der beiden Schenkel 8 vorgesehen ist. Die einander gegenüberstehenden freien Enden der Schenkel 8 weisen jeweils eine angeschrägte Fläche 10 auf, die zum Inneren des Schlitzes 7 hin geneigt ist. Die beiden angeschrägten Fläche bilden eine Einführhilfe für den Stift 1 bei der Montage der Schalthebelverbindung. Der Schlitz 7 ist in axialer Richtung durch den Schalthebel 3 hindurch und in radial nach aussen verlaufender Richtung auf das von der Schwenkachse 2 abgewandte Ende des Hebelgriffs 5 geführt. Die angeschrägten Flächen 10 schneiden sich mit den auf den Griff 5 geführten Begrenzungsflächen des Schlitzes 7 in zwei die Hinterschneidung 9 nach aussen begrenzenden Kanten. Die Hinterschneidung 9 weitet sich hinter diesen beiden Kanten zunächst auf und verjüngt sich dann kontinuierlich bis auf die Breite des Schlitzes 7.As can be seen from FIG. 2, but in particular from FIG. 3, two flexible legs 8 spaced apart from one another by a slot 7 are formed in the handle 5 as an expansion part 6. The slot 7 has an undercut 9 adapted to the profile of the pin 1, which is provided in the region of the free ends of the two legs 8. The opposite free ends of the legs 8 each have a beveled surface 10 which is inclined towards the interior of the slot 7. The two beveled surfaces form an insertion aid for pin 1 when assembling the shift lever connection. The slot 7 is guided in the axial direction through the shift lever 3 and in the radially outward direction to the end of the lever handle 5 facing away from the pivot axis 2. The beveled surfaces 10 intersect with the boundary surfaces of the slot 7 guided on the handle 5 into two edges which delimit the undercut 9 towards the outside. The undercut 9 initially widens behind these two edges and then tapers continuously down to the width of the slot 7.

Aus Fig.4 ist der Aufbau des Stifts 1 ersichtlich. Dieser Stift ist vorzugsweise zylinderförmig ausgebildet. Statt rundes Profil kann er aber auch irgendein anderes in die Hinterschneidung 9 des Schlitzes 7 passendes Profil aufweisen und beispielsweise elliptischen, halbrunden, quadratischen oder rechteckigen Querschnitt aufweisen. Wichtig ist vor allem, dass der Stift nach Aufspreizen der Schenkel 8 des Spreizteils 6 derart in der Hinterschneidung 9 gelagert ist, dass er ohne grossen Kraftaufwand nicht mehr nach aussen entfernt werden kann. Je nach Durchmesser des Stifts 1 und Grösse der Hinterschneidung ist der Stift 1 in der Hinterschneidung 9 eingespreizt und eingeklemmt oder lediglich eingespreizt gehalten. Diese unterschiedlichen Halterungen können durch nicht zu vermeidende Fertigungstoleranzen hervorgerufen werden. Um zu verhindern, dass der lediglich durch die Spreizwirkung der Schenkel 8 gehaltene Stift 1 gegebenenfalls in Richtung der Schwenkachse 2 aus den Hinterschneidungen 9 entfernt werden kann, weist der Stift 1 mindestens eine zwischen zwei Schalthebeln angeordnete Verdickung 11 auf. Diese Verdickung 11 kann besonders einfach und kostengünstig durch Kerbwirkung erzeugt werden. Im allgemeinen reicht das Einprägen von beispielsweise drei oder vier Kerben 12 zur Erzeugung einer das seitliche Entfernen des Stiftes 1 mit grosser Sicherheit verhindernden Verdickung 11 bereits aus.The structure of the pin 1 can be seen from FIG. This pin is preferably cylindrical. Instead of a round profile, it can also have any other profile that fits into the undercut 9 of the slot 7 and, for example, can have an elliptical, semicircular, square or rectangular cross section. It is particularly important that after the legs 8 of the expansion part 6 have been spread open, the pin in the undercut 9 is stored so that it can no longer be removed from the outside without great effort. Depending on the diameter of the pin 1 and the size of the undercut, the pin 1 is spread and clamped in the undercut 9 or is only kept spread. These different brackets can be caused by unavoidable manufacturing tolerances. In order to prevent the pin 1, which is only held by the spreading action of the legs 8, from being removed from the undercuts 9 in the direction of the pivot axis 2, the pin 1 has at least one thickening 11 arranged between two switching levers. This thickening 11 can be produced particularly easily and inexpensively by the notch effect. In general, the embossing of, for example, three or four notches 12 is sufficient to produce a thickening 11 which prevents the lateral removal of the pin 1 with great certainty.

Die Schalthebelverbindung nach der Erfindung kann besonders einfach und kostengünstig hergestellt werden. Dies ist zum einen deswegen möglich, da in das zur Herstellung des in allgemeinen spritzgegossenen Schalthebels 3 verwendete Werkzeug der Schlitz 7 und die Hinterschneidung 9 ohne zusätzlichen Aufwand eingeformt werden können. Zum anderen ist dies auch deswegen möglich, da der Stift 1 durch Ablängen leicht an eine erwünschte Baulänge angepasst und der abgelängte Stift unter starrer Kopplung der drei Schalthebel 3 ohne grossen Montageaufwand quer zur Schwenkchse 2 in die Schlitze 7 bzw. die Hinterschneidungen 9 eingepasst werden kann.The shift lever connection according to the invention can be produced particularly simply and inexpensively. On the one hand, this is possible because the slot 7 and the undercut 9 can be molded into the tool used to manufacture the generally injection-molded shift lever 3 without additional effort. On the other hand, this is also possible because the pin 1 can be easily adapted to a desired overall length by cutting to length and the cut pin can be fitted into the slots 7 or the undercuts 9 transversely to the swivel axis 2 without rigid assembly of the three shift levers 3 .
