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 a such a shift lever connection becomes a synchronous actuation the pole of a multi-pole switching device is reached. Is preferred such a shift lever connection in switching devices, such as especially line fault current or motor protection switches from Low voltage distributors used. Such switches have often two, three, four or possibly even more than four like 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 takes on a prior art of shift lever connection Reference, as in that of the patent applicant in autumn 1989 published manual "Innovative installation with smissline" is shown on p.6. The shift lever connection after the Prior art contains a sheet bent as a U-shape trained bridge part. This sheet is two or three around a common axis swiveling and each as an operating handle trained lever arms of the shift lever of a two-or three-pole circuit breaker and thus causes the rigid coupling of the shift 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.In DE-A-25 40 745 a shift lever connection is described in of the individual shift levers 6 with a bridge part 9 molded nubs 8 are interconnected. The knobs 8 have lugs 15, which with fixation of the bridge part 9 in Windows 14 of the centrally guided recesses 7 of the shift lever are locked. Such a shift lever connection is relative elaborate because the complicated, window-like in each gear lever extended, centrally guided recess is to be made, and there the bridge part is 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 set out in claim 1 lies the task is based on a gear lever connection of the beginning Specify the type mentioned in a simple and one for one 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.

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 Figures 1 and 2 does not have a pin 1 and three about a common axis 2 of the Switching device shown pivotable shift lever 3. The Shift levers 3 are made of a plastic, typically one Thermoplastic, for example based on an amide, and are formed each in a pole housing, also not shown Switchgear pivoted about axis 2. The three poles can be designed as circuit breakers if the switchgear is designed for example, the three phases of a three-phase system. Each of the three shift levers 3 is designed with two arms and has each with an actuating element, not shown on a contact arrangement acting lever arm 4 and a trained as a handle 5 and from the pole housing of the switching device further lever arm led to the outside. To a synchronous switching of the independently manufactured Switch poles to enable guided phases have the Lever handles each have an elastically deformable expansion part 6 and is in the expansion parts 6 parallel to the pivot axis 2nd aligned pin 1 pressed.

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 in the handle 5 as an expansion part 6 two through a slot 7 spaced apart, bendable legs 8 are formed. Of the Slot 7 has an adapted to the profile of the pin 1 Undercut 9, which in the area of the free ends of the two legs 8 is provided. The opposing ones free ends of the legs 8 each have a beveled Surface 10, which is inclined towards the interior of the slot 7. The two bevelled surfaces form an insertion aid for the Pin 1 when assembling the gear lever connection. The slot 7 is in the axial direction through the shift lever 3 and in radially outward direction to that of the Swivel axis 2 remote end of the lever handle 5 out. The bevelled surfaces 10 intersect with those on the handle 5 guided boundary surfaces of the slot 7 in two Undercut 9 to the outside bounding edges. The Undercut 9 widens behind these two edges initially on 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 pen is preferably cylindrical. Instead of a round profile but he can also any other in the undercut 9 of the Have slot 7 matching profile and, for example, elliptical, semicircular, square or rectangular cross-section exhibit. It is particularly important that the pen after spreading the leg 8 of the expansion part 6 in this way in the undercut 9 is stored in such a way that it can no longer be adjusted without great effort can be removed outside. Depending on the diameter of the pin 1 and The size of the undercut is pin 1 in the undercut 9 spread and pinched or only spread held. These different brackets cannot manufacturing tolerances to be avoided. In order to prevent the only by the spreading effect of Leg 8 held pin 1 optionally in the direction of Pivot axis 2 can be removed from the undercuts 9, the pin 1 has at least one between two shift levers arranged thickening 11. This thickening 11 can be special can be produced simply and inexpensively by notching. in the in general, for example, three or three is enough four notches 12 to produce a side removal of the Pin 1 with great security preventing thickening 11th already out.

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 special be manufactured easily and inexpensively. On the one hand, this is therefore possible, because in the manufacture of the in general injection molded shift lever 3 used the slot 7 and the undercut 9 are molded in without additional effort can be. On the other hand, this is also possible because the Pin 1 is easily cut to a desired length adjusted and the cut pin under rigid coupling of the three shift levers 3 without great assembly effort across Swivel axis 2 into the slots 7 or the undercuts 9 can be fitted.
