Description

Die Erfindung betrifft eine Steckvorrichtung zum Anschluss eines Steckers, insbesondere in explosionsgefährdeten Bereichen. Die Steckvorrichtung kann eine Wandsteckdose, Flanschsteckdose, Kupplung oder dergleichen sein. Sie weist ein Gehäuse mit beispielsweise zumindest einer Flanschdose mit einem Steckdoseneinsatz mit mindestens einer Buchse auf.The invention relates to a plug device for connecting a plug, in particular in areas at risk of explosion. The plug device can be a wall socket, flange socket, coupling or the like. It has a housing with, for example, at least one flange socket with a socket insert with at least one socket.

Ein entsprechendes Material für solche Steckvorrichtungen, insbesondere deren Gehäuse, ist Polyamid, glasfaserverstärktes und schlagfestes Polyester, Edelstahl oder dergleichen. Die entsprechende Flanschdose kann zwei-, drei-, vier-, fünf- oder auch mehrpolig ausgebildet sein. In der Regel ist eine solche Flanschdose durch eine Schutzkappe lösbar verschlossen. Die Steckvorrichtung wird insbesondere zum Einsatz in gas- und staubexplosionsgefährdeten Bereichen verwendet und wird über einen separaten Gerätehalter an einer Wand, am Boden, einer Gitterrinne, einem Rohr oder dergleichen befestigt.A corresponding material for such plug-in devices, in particular their housing, is polyamide, glass fiber-reinforced and impact-resistant polyester, stainless steel or the like. The corresponding flange socket can be designed with two, three, four, five or even multiple poles. As a rule, such a flange socket is releasably closed by a protective cap. The plug-in device is used in particular for use in areas where there is a risk of gas and dust explosions and is attached to a wall, floor, mesh cable tray, pipe or the like via a separate device holder.

Die Steckvorrichtung dient über den Stecker zum Anschluss von mobilen oder auch festen Geräten in solchen Bereichen, wobei diese über die Steckvorrichtung mit Energie versorgt werden.The plug-in device is used via the plug to connect mobile or fixed devices in such areas, whereby these are supplied with energy via the plug-in device.

DE 200 21 374 U1 offenbart eine Steckvorrichtung, insbesondere elektrische Steckdose, zur Verbindung mit einem entsprechenden Stecker. Die Steckdose weist ein Steckdosengehäuse sowie einen Warnhinweis beispielsweise in Form einer Warnlampe auf. Diese soll beispielsweise bei einem entfernten Verriegelungsteil rot aufleuchten. Ebenfalls möglich ist ein lesbarer Warnhinweis, wie beispielsweise "nicht in explosionsgefährdeten Bereichen benutzen". DE 200 21 374 U1 discloses a plug device, in particular an electrical socket, for connection to a corresponding plug. The socket has a socket housing and a warning notice, for example in the form of a warning lamp. This should light up red, for example, when a locking part is removed. A legible warning such as "do not use in potentially explosive areas" is also possible.

Aufgabe vorliegender Erfindung ist, eine Steckvorrichtung der vorangehend beschriebenen Art dahingehend zu verbessern, dass für einen Benutzer in einfacher und sicherer Weise feststellbar ist, ob die Steckvorrichtung einsatzbereit ist.The object of the present invention is to improve a plug-in device of the type described above in such a way that a user can determine in a simple and reliable manner whether the plug-in device is ready for use.

Diese Aufgabe wird durch die Merkmale des Patentanspruchs 1 gelöst. Die erfindungsgemäße Lösung zeichnet sich insbesondere dadurch aus, dass auf einer Gehäuseaußenseite des Gehäuses der Steckvorrichtung wenigstens eine Anzeigelampe sichtbar ist. Diese kann beispielsweise anzeigen, dass die Steckvorrichtung zur Energieversorgung einsetzbar ist. Für eine solche Anzeige ist es generell ausreichend, wenn die Anzeigelampe ein- oder ausgeschaltet ist. Bei einer eingeschalteten Anzeigelampe ist dies ein Hinweis auf eine entsprechend verwendbare Energieversorgung mittels der Steckvorrichtung. Die Anzeigelampe ist an sich explosionsgeschützt ausgebildet. Die Abdeckung kann eingefärbt sein. Da Anzeigelampe auf einer Oberseite des Gehäuses angeordnet ist, ist sie in der Regel frei sichtbar, sodass bereits aus einem größeren Abstand feststellbar ist, ob die entsprechende Steckvorrichtung zur Energieversorgung einsatzbereit ist.This object is achieved by the features of claim 1. The solution according to the invention is particularly characterized in that at least one indicator lamp is visible on the outside of the housing of the plug-in device. This can indicate, for example, that the plug-in device can be used for energy supply. For such a display it is generally sufficient if the indicator lamp is switched on or off. When the indicator lamp is switched on, this is an indication of a correspondingly usable energy supply by means of the plug-in device. The indicator lamp is designed to be explosion-proof. The cover can be colored. Since the indicator lamp is arranged on an upper side of the housing, it is usually freely visible, so that It is already possible to determine from a greater distance whether the corresponding plug-in device is ready for use for the energy supply.

Erfindungsgemäß sind noch andere Parameter oder Informationen mittels der Anzeigelampe darstellbar. Solche Parameter beziehungsweise Informationen betreffen beispielsweise ob eine entsprechende Drei-Phasen-Wechselspannung oder ein entsprechender Drei-Phasen-Wechselstrom anliegt, ob eine Wartung erforderlich ist, ob bei Verbindung/Trennung der Energieversorgung diese korrekt ausgeführt wurde, ob die erforderliche Spannung anliegt, und dergleichen. Alle diese Parameter und Informationen sind insbesondere auch zusammen mit der Einsatzbereitschaft zur Energieversorgung anzeigbar, wenn die Anzeigelampe mit unterschiedlichen Farben und/oder Helligkeiten betreibbar ist. Dies kann beispielsweise bedeuten, dass bei einer roten Farbe der Anzeigelampe eine ausreichende Energieversorgung vorliegt, bei einer gelben Farbe der Anzeigelampe eine Wartung erforderlich ist usw. Dabei ist zur Variation der angezeigten Information mittels der Anzeigelampe, die Anzeigelampe in Dauer- und/oder Taktbetrieb einsetzbar. Dauerbetrieb bedeutet in diesem Zusammenhang, dass die Anzeigelampe konstant leuchtet, während sie im Taktbetrieb mit bestimmter Frequenz leuchtet beziehungsweise dunkel geschaltet ist. Um die Anzeigelampe von verschiedenen Positionen in einfacher Weise sehen zu können, kann die Anzeigelampe zumindest teilweise von der Gehäuseaußenseite vorstehen.According to the invention, other parameters or information can also be displayed by means of the display lamp. Such parameters or information relate, for example, to whether a corresponding three-phase alternating voltage or a corresponding three-phase alternating current is present, whether maintenance is required, whether the connection / disconnection of the power supply was carried out correctly, whether the required voltage is present, and the like . All of these parameters and information can in particular also be displayed together with the readiness for use of the energy supply if the display lamp can be operated with different colors and / or brightnesses. This can mean, for example, that there is sufficient energy supply if the indicator lamp is red, maintenance is required if the indicator lamp is yellow, etc. The indicator lamp can be used in continuous and / or cyclical operation to vary the information displayed by means of the indicator lamp . In this context, continuous operation means that the indicator lamp lights up constantly while it lights up or is switched to dark in cyclic operation with a certain frequency. In order to be able to see the indicator lamp from different positions in a simple manner, the indicator lamp can at least partially protrude from the outside of the housing.

Außerdem besteht die Möglichkeit, durch Variation der Helligkeit beispielsweise darzustellen, dass eine entsprechende Steckvorrichtung zwar einsatzbereit, aber bereits belegt ist. D. h., bei einer Einsatzbereitschaft leuchtet die Anzeigelampe gegebenenfalls heller und bei einer Belegung dunkler.There is also the possibility, for example, of varying the brightness to show that a corresponding plug-in device is ready for use but is already occupied. This means that the indicator lamp may be brighter when it is ready for use and darker when it is occupied.

Um insbesondere unterschiedliche Farben auch gegebenenfalls unabhängig voneinander darstellen zu können, kann die Anzeigelampe zwei, drei oder mehr Leuchtmittel aufweisen. Diese weisen unterschiedliche Farben auf und sind gegebenenfalls ebenso in ihrer Helligkeit variierbar.In order, in particular, to be able to display different colors also optionally independently of one another, the indicator lamp can have two, three or more illuminants. These have different colors and their brightness can also be varied if necessary.

In diesem Zusammenhang kann es weiterhin von Vorteil sein, wenn im Taktbetrieb unterschiedliche Taktfrequenzen einstellbar und/oder vorgegeben sind. D. h., falls beispielsweise die Taktfrequenz relativ niedrig ist, kann dies ein Hinweis auf eine Einsatzbereitschaft der Steckvorrichtung sein und gleichzeitig anzeigen, dass diese unbelegt ist. Ist die Tragfrequenz sehr hoch, kann dies bedeuten, dass die Steckvorrichtung belegt ist.In this context, it can also be advantageous if different clock frequencies can be set and / or specified in cyclic operation. That is, if, for example, the clock frequency is relatively low, this can indicate that the plug-in device is ready for use and at the same time indicate that it is unoccupied. If the load frequency is very high, this can mean that the connector is occupied.

Um alle entsprechenden Schaltmaßnahmen bei insbesondere mehreren Leuchtmitteln oder auch Taktbetrieb der Anzeigelampe in einfacher Weise zu ermöglichen, kann die Steckvorrichtung einen Mikrocontroller aufweisen.In order to enable all corresponding switching measures, in particular with a plurality of lighting means or also clock operation of the indicator lamp, in a simple manner, the plug-in device can have a microcontroller.

Bei einer Weiterentwicklung der Steckvorrichtung kann es sich als günstig erweisen, wenn der Mikrocontroller werkseitig und insbesondere drahtlos ansprechbar und programmierbar ist. Auf diese Weise lassen sich vor Auslieferung der Steckvorrichtung durch entsprechende Programmierung unterschiedliche Funktionen mittels der Anzeigelampe darstellen. Ebenso kann der Mikrocontroller direkt ansprechbar sein, um beispielsweise die Funktion der Anzeigelampe und deren Programmierung auch von entfernter Stelle abzurufen und zu überprüfen.In the case of a further development of the plug-in device, it can prove to be advantageous if the microcontroller can be addressed and programmed in the factory and, in particular, wirelessly. In this way, prior to delivery of the plug-in device, different functions can be represented by means of the indicator lamp by means of appropriate programming. Likewise, the microcontroller can be addressed directly, for example to call up and check the function of the indicator lamp and its programming from a remote location.

Es sind verschiedene Leuchtmittel für die Anzeigelampe denkbar. Ein Leuchtmittel mit niedrigem Energiebedarf und hoher Lebensdauer, welches ebenfalls in vielen Farben vorliegt, ist eine Licht emittierende Diode (LED). Eine solche LED kann als Einzel-LED oder auch als Gruppe von LEDs vorliegen. Dies gilt ebenfalls bei Leuchtmittel mit unterschiedlichen Farben, die ebenfalls durch LEDs realisiert werden können.Different light sources are conceivable for the indicator lamp. A light-emitting diode (LED) is a light source with low energy requirements and a long service life, which is also available in many colors. Such an LED can be present as a single LED or as a group of LEDs. This also applies to light sources with different colors, which can also be implemented using LEDs.

Im Folgenden werden vorteilhafte Ausführungsbeispiele der Erfindung anhand der in der Zeichnung beigefügten Figuren erläutert.In the following, advantageous exemplary embodiments of the invention are explained with reference to the figures enclosed in the drawing.

Figure 2

In Figur 1 ist eine perspektivische Seitenansicht eines ersten Ausführungsbeispiels dargestellt. Die entsprechende Steckvorrichtung 1 weist an einer nach rechts weisenden Seite eine Flanschdose 3 auf, die mittels einer Schutzkappe 9 verschließbar ist. Die entsprechende Flanschdose 3 steht aus einem Gehäuse 2 der Steckvorrichtung 1 vor und ist beispielsweise zwei-, drei-, vier-, fünf- oder mehrpolig ausgebildet. Das Gehäuse 2 ist in etwa kastenförmig und weist eine Gehäuseaußenseite 5 auf. Auf dieser und insbesondere auf einer Oberseite des Gehäuses 2 ist neben einem Schalter 11 eine Anzeigelampe 4 angeordnet. Diese ist insbesondere für den Einsatz in explosionsgefährdeten Bereichen mit einer explosionsgeschützten Abdeckung 6 ausgebildet, die im oberen Bereich einen kuppelförmigen und transparenten Abschnitt aufweist. Die Anzeigelampe 4 steht teilweise von der Gehäuseoberseite 7 vor. Das Gehäuse weist weiterhin seitliche Montagemittel 10 insbesondere zur Befestigung an Montageplatten auf, die in der Regel zur Befestigung der Steckvorrichtung 1 an einer Wand, an einer Gitterrinne, an einem Rohr oder dergleichen dienen.In Figure 1 is a perspective side view of a first embodiment shown. The corresponding plug-in device 1 has a flange socket 3 on a side pointing to the right, which can be closed by means of a protective cap 9. The corresponding flange socket 3 protrudes from a housing 2 of the plug-in device 1 and is, for example, two-, three-, four-, five-pole or multi-pole. The housing 2 is roughly box-shaped and has an outer side 5 of the housing. On this, and in particular on an upper side of the housing 2, an indicator lamp 4 is arranged next to a switch 11. This is designed in particular for use in potentially explosive areas with an explosion-proof cover 6, which has a dome-shaped and transparent section in the upper area. The indicator lamp 4 partially protrudes from the top 7 of the housing in front. The housing also has lateral mounting means 10, in particular for attachment to mounting plates, which are generally used to attach the plug-in device 1 to a wall, to a mesh cable tray, to a pipe or the like.

Innerhalb des Gehäuses 2 ist ein Mikrocontroller 8 angeordnet, der in Figur 1 gestrichelt dargestellt ist.A microcontroller 8 is arranged inside the housing 2, which is shown in FIG Figure 1 is shown in dashed lines.

Der entsprechende Schalter 11 dient zum Ein- beziehungsweise Ausschalten der Steckvorrichtung 1. Über die entsprechende Flanschdose 3 ist ein nicht dargestellter Stecker anschließbar. Dessen Befestigung und das entsprechende Freischalten der Spannungsversorgung mittels der Steckvorrichtung 1 erfolgt in der Regel über ein Einstecken des Steckers in die Flanschdose und ein Verdrehen des Schalters.The corresponding switch 11 is used to switch the plug device 1 on and off. A plug (not shown) can be connected via the corresponding flange socket 3. Its attachment and the corresponding activation of the voltage supply by means of the plug-in device 1 is usually carried out by inserting the plug into the flange socket and rotating the switch.

Die Anzeigelampe 4 dient zur Anzeige beispielsweise der Einsatzbereitschaft der Steckvorrichtung hinsichtlich einer entsprechenden Energieversorgung. Die Anzeigelampe kann allerdings auch weitere Informationen beziehungsweise Parameter hinsichtlich der Steckvorrichtung 1 zusätzlich zu dieser Bereitschaft zur Energieversorgung oder auch alternativ zu dieser anzeigen. Beispielsweise kann angezeigt werden, dass eine korrekte Drei-Phasen-Wechselspannungs- oder Wechselstromversorgung vorliegt. Es kann ebenfalls angezeigt werden, dass eine Wartung der Steckvorrichtung erforderlich ist. Weiterhin kann unter anderem dargestellt werden, dass die erforderliche Spannung anliegt.The indicator lamp 4 is used to display, for example, the readiness for use of the plug-in device with regard to a corresponding energy supply. The indicator lamp can, however, also display further information or parameters with regard to the plug-in device 1 in addition to this readiness for energy supply or also as an alternative to this. For example, it can be indicated that there is a correct three-phase AC voltage or AC power supply. It can also indicate that the connector needs servicing. Furthermore, it can be shown, among other things, that the required voltage is present.

Die Anzeigelampe weist ein entsprechendes Leuchtmittel auf, wobei auch zwei, drei oder mehr Leuchtmittel verwendet werden können. Ein Beispiel für ein solches Leuchtmittel ist eine LED, d. h. eine Licht emittierende Diode. Diese weist einen niedrigen Energiebedarf bei hoher Lebensdauer auf. Die Farbe des entsprechenden Leuchtmittels kann weiß oder auch farbig sein. Solche LEDs sind auch als weiße, rote, gelbe oder andersfarbige Leuchtmittel einsetzbar. Weiterhin besteht die Möglichkeit, dass die Anzeigelampe nicht im Dauerbetrieb eingesetzt wird, d. h. konstant Licht abgibt, sondern dass ein periodisches oder taktweises Aufleuchten erfolgt. D. h., die Anzeigelampe ist für den Dauer- und/oder Taktbetrieb einsetzbar. In Zusammenhang mit dem Taktbetrieb sind unterschiedliche Taktfrequenzen einstellbar oder vorgegeben, wobei eine entsprechende Einstellung oder Vorgabe mittels des Mikrocontrollers 8 erfolgen kann.The indicator lamp has a corresponding illuminant, it also being possible to use two, three or more illuminants. An example of such a light source is an LED, i. H. a light emitting diode. This has a low energy requirement with a long service life. The color of the corresponding light source can be white or colored. Such LEDs can also be used as white, red, yellow or other colored light sources. There is also the possibility that the indicator lamp is not used continuously, i. H. constantly emits light, but that it lights up periodically or in cycles. In other words, the indicator lamp can be used for continuous and / or cyclical operation. In connection with the cyclic operation, different clock frequencies can be set or specified, it being possible for a corresponding setting or specification to be made by means of the microcontroller 8.

Zur entsprechenden Steuerung oder Einstellung der Steckvorrichtung kann dieser Mikrocontroller werkseitig und insbesondere drahtlos ansprechbar und programmierbar sein.For the corresponding control or setting of the plug-in device, this microcontroller can be addressed and programmed in the factory and in particular wirelessly.

Außerdem besteht die Möglichkeit, dass insbesondere bei verschieden farbigen Leuchtmitteln der Anzeigelampe oder auch bei Verwendung von zwei oder mehr Anzeigelampen, mehrere entsprechende Parameter beziehungsweise Informationen unabhängig voneinander und gleichzeitig dargestellt werden, siehe die obigen Ausführungen zu solchen Parametern und Informationen.In addition, there is the possibility that, in particular with different colored illuminants of the indicator lamp or even when using two or more indicator lamps, several corresponding parameters or information are displayed independently and simultaneously, see the above explanations on such parameters and information.

In Figur 2 ist eine perspektivische Ansicht von schräg hinten auf ein zweites Ausführungsbeispiel einer erfindungsgemäßen Steckvorrichtung 1 dargestellt. Diese entspricht im Wesentlichen der Steckvorrichtung nach Figur 1 bis auf die Anordnung eines Schalters 11 auf der Oberseite 7 des Gehäuses 2. Auch bei diesem Ausführungsbeispiel der Steckvorrichtung ist eine entsprechende Anzeigelampe 4 mit einer explosionsgeschützten Abdeckung 6 auf der Oberseite 7 als Teil der Gehäuseaußenseite 5 des Gehäuses 2 angeordnet.In Figure 2 is a perspective view obliquely from the rear of a second embodiment of a connector 1 according to the invention. This essentially corresponds to the plug-in device Figure 1 except for the arrangement of a switch 11 on the upper side 7 of the housing 2. In this exemplary embodiment of the plug-in device, too, a corresponding indicator lamp 4 with an explosion-proof cover 6 is arranged on the upper side 7 as part of the outer side 5 of the housing 2.

Wie bereits ausgeführt, wird zum Einschalten der Energieversorgung mittels der Steckvorrichtung 1 ein entsprechender Stecker mit einem Steckdosenbuchseneinsatz verdreht, wobei auch eine Bestätigung einer korrekten Drehrichtung durch die Anzeigelampe 4 dargestellt werden kann.As already stated, in order to switch on the power supply by means of the plug device 1, a corresponding plug with a socket outlet insert is rotated, it also being possible for a confirmation of a correct direction of rotation to be displayed by the indicator lamp 4.

Die Ausführungen in Zusammenhang mit Figur 1 gelten ebenso für das Ausführungsbeispiel nach Figur 2.The explanations in connection with Figure 1 also apply to the embodiment according to Figure 2 .
