- a switching device which can be actuated via a so-called stepping mechanism.
- a stepping mechanism typically comprises a switching wheel which can be actuated by a slide switch or switch ram and which is further rotated in each direction by a generally fixed angle in a direction of rotation. The often star-like or polygonal circumference of the ratchet acts on the switching contact and moves it between its switching positions.
- a switch position display comprises at least one color-coded and / or provided with a word message display field, which in at least one Display position is visible through a housing window from the outside.
- a number of display fields is provided corresponding to the number of possible operating states, whereby, depending on the current operating state, the corresponding display field is always visible from the outside.
- An equivalent variant for displaying the current operating state is that a display field or display element in the manner of a pointer in several display positions through the housing window is visible, and the current operating state is done by the position of the display panel within the window area.
- Switch position display Core requirements for a switch position display are that it should show the operating status of the device in a clear way. Furthermore, the mechanism required for the switch position display should not impair the device function.

Description
Die Erfindung bezieht sich auf ein elektrisches Schaltgerät, insbesondere Reiheneinbaugerät, mit einer Schaltstellungsanzeige, durch welche der Betriebszustand des Schaltgeräts nach außen hin sichtbar angezeigt wird.The invention relates to an electrical switching device, in particular DIN rail mounted device, with a switch position display, by which the operating state of the switching device is visibly displayed to the outside.
Bei einem solchen Schaltgerät ist es oftmals wünschenswert, den Betriebszustand des Gerätes, d.h. die aktuelle Schaltstellung seines Schaltkontakts für einen Anwender auf markante Weise sichtbar zu machen. Insbesondere bei Reiheneinbaugeräten, die häufig in Gruppen von vielen Einzelschaltgeräten eingesetzt werden, dient eine solche Schaltstellungsanzeige der besseren Übersicht und somit z.B. der schnelleren Auffindung von Fehlerquellen etc. Eine Schaltstellungsanzeige ist vor allem bei einem fernbetätigbaren Schaltgerät erforderlich, bei welchem entweder kein Handbetrieb vorgesehen ist, oder bei dem der Betriebszustand des Geräts nicht eindeutig an der Stellung des Handbetätigungselements abzulesen ist.In such a switching device, it is often desirable to control the operating state of the device, i. To make the current switching position of its switch contact for a user in a striking way visible. In particular, in the case of DIN rail mounted devices, which are frequently used in groups of many individual switching devices, such a switching position indicator serves for a better overview and thus, for the faster finding of sources of error, etc. A switch position indicator is required especially in a remotely controllable switching device in which either no manual operation is provided, or in which the operating state of the device is not clearly read on the position of the manual element.
Zur letztgenannten Gruppe zählt ein Schaltgerät, das über ein sogenanntes Schrittschaltwerk betätigbar ist. Ein solches ist an sich beispielsweise aus der
Üblicherweise umfasst eine Schaltstellungsanzeige mindestens ein farblich gekennzeichnetes und/oder mit einer Wortbotschaft versehenes Anzeigefeld, welches in mindestens einer Anzeigestellung durch ein Gehäusefenster von außen sichtbar ist. Häufig ist eine der Anzahl von möglichen Betriebszuständen entsprechende Anzahl von Anzeigefeldern vorgesehen, wobei je nach aktuellem Betriebszustand stets das korrespondierende Anzeigefeld von außen sichtbar ist.Usually, a switch position display comprises at least one color-coded and / or provided with a word message display field, which in at least one Display position is visible through a housing window from the outside. Frequently, a number of display fields is provided corresponding to the number of possible operating states, whereby, depending on the current operating state, the corresponding display field is always visible from the outside.
Eine äquivalente Variante zur Anzeige des aktuellen Betriebszustandes besteht darin, dass ein Anzeigefeld oder Anzeigeelement nach Art eines Zeigers in mehreren Anzeigestellungen durch das Gehäusefenster sichtbar ist, und der aktuelle Betriebszustand durch die Stellung des Anzeigefeldes innerhalb der Fensterfläche geschieht.An equivalent variant for displaying the current operating state is that a display field or display element in the manner of a pointer in several display positions through the housing window is visible, and the current operating state is done by the position of the display panel within the window area.
Kernanforderungen an eine Schaltstellungsanzeige sind, dass diese den Betriebszustand des Geräts in eindeutiger Weise zeigen soll. Weiterhin soll die für die Schaltstellungsanzeige erforderliche Mechanik die Gerätefunktion nicht beeinträchtigen. Aus wirtschaftlichen Erwägungen heraus sollte die Schaltstellungsanzeige ferner möglichst einfach aufgebaut sein, um die Materialkosten und den Montageaufwand gering zu halten.Core requirements for a switch position display are that it should show the operating status of the device in a clear way. Furthermore, the mechanism required for the switch position display should not impair the device function. For economic considerations, the switch position indicator should also be as simple as possible to keep the cost of materials and assembly costs low.
Der Erfindung liegt die Aufgabe zugrunde, ein elektrisches Schaltgerät mit einer im Hinblick auf die oben genannten Anforderungen ertüchtigten Schaltstellungsanzeige anzugeben.The invention has for its object to provide an electrical switching device with an improved in view of the above requirements switch position indicator.
Das Dokument
Die Aufgabe wird erfindungsgemäß gelöst durch die Merkmale des Patentanspruchs 1. Danach umfasst die Schaltstellungsanzeige einen schwenkbar gelagerten Anzeigehebel mit einem Anzeigefeld, welches in mindestens einer Anzeigestellung des Anzeigehebels durch ein Gehäusefenster von außen sichtbar ist. Ein Antriebsteil des Anzeigehebels wirkt dabei derart mit dem Schaltrad eines Schrittschaltwerks zusammen, dass das Antriebsteil in einem, dem Betriebszustand eindeutig zuordbaren Radius von der Drehachse des Schaltrads gehalten ist.The object is achieved by the features of claim 1. Thereafter, the switch position indicator comprises a pivotally mounted indicator lever with a display panel which is visible in at least one display position of the indicator lever by a housing window from the outside. A drive part of the indicator lever acts in such a way with the ratchet wheel of a stepping mechanism that the drive part is held in a, the operating state uniquely assignable radius of the axis of rotation of the ratchet wheel.
Durch einen solchen Anzeigehebel ist eine einfache, insbesondere sehr wenige Teile umfassende Mechanik zur Anzeige des Betriebszustandes realisiert. Ein besonderer Vorteil liegt darin, dass der Anzeigehebel antriebsmäßig mit dem Schaltrad verbunden ist, welches bei einem Schrittschaltwerk häufig ohnehin vorhanden ist.By such a display lever a simple, in particular very few parts comprehensive mechanism for displaying the operating state is realized. A particular advantage is that the indicator lever is drivingly connected to the ratchet, which is often present anyway in a stepper.
In einer leichtgängigen und fehlfunktionssicheren Ausführung der Erfindung ist eine in eine Stirnseite des Schaltrads eingebrachte Kulissenführung vorgesehen, in die ein Führungszapfen des Anzeigehebels als Antriebsteil hineinragt. Bevorzugt ist diese Kulissenführung dabei durch eine ringartig geschlossene Führungsnut gebildet.In a smooth and malfunction-resistant embodiment of the invention, a sliding guide introduced into an end face of the indexing wheel is provided, into which a guide pin of the indicating lever projects as a drive part. Preferably, this link guide is formed by a ring-like closed guide.
Eine sternartige oder polygonartige Formgebung der Kulissenführung ist besonders vorteilhaft, zumal hierbei der Abstand zwischen der Drehachse des Schaltrads und dem Eingriffspunkt des Antriebsteils in die Kulissenführung bei einer Drehung des Schaltrads kontinuierlich variiert wird. Durch ausgerundete Ecken der Stern- oder Polygonform ist eine reibungsarme und verkantungsfreie Führung des Antriebsteils sichergestellt.A star-like or polygonal shape of the slotted guide is particularly advantageous, especially since the distance between the axis of rotation of the ratchet wheel and the point of engagement of the drive member in the slotted guide in a rotation of the ratchet wheel is continuously varied. By rounded corners of the star or polygon shape a low-friction and tilt-free guidance of the drive member is ensured.
Zur Vereinfachung des Montageaufwands ist der Anzeigehebel bevorzugt einstückig ausgeführt.To simplify the assembly work, the indicator lever is preferably made in one piece.
Hinsichtlich der Materialeigenschaften, insbesondere Elastizität und Materialfestigkeit ist Kunststoff, insbesondere Polyoxymethylen (POM) oder Polyamid (PA) als Material für den Anzeigehebel besonders geeignet. Damit ist insbesondere die Herstellung des Anzeigehebels als preisgünstiges Spritzteil ermöglicht.With regard to the material properties, in particular elasticity and material strength, plastic, in particular polyoxymethylene (POM) or polyamide (PA) is particularly suitable as material for the indicator lever. Thus, in particular the production of the display lever is made possible as a low-cost molded part.
