Abstract
Explosionsgeschützte Betriebsmittel zur Verwendung in überwachten Stromkreisen sollen dahingehend verbessert werden, dass die Verkabelung der Betriebsmittel vereinfacht und damit bedienungsfreundlicher wird und das Ver- und Entkabeln im laufenden Betrieb durch Verhinderung des Entstehens von Zündfunken ermöglicht wird. DOLLAR A Für diese Verbesserung wird vorgeschlagen, werksseitig Steckverbinder in das Gehäuse zu integrieren und im Gehäuse anzuschließen, sodass die Verkabelung über ebenfalls mit Steckverbindern versehene Kabel erfolgen kann, die mit den Steckverbindern der Betriebsmittel verbunden werden, ohne dass das Betriebsmittel dafür geöffnet werden muss, Kabel eingezogen, abisoliert und angeschlossen werden müssen und das Betriebsmittel wieder geschlossen werden muss. DOLLAR A Ferner wird vorgeschlagen, den Kontaktstift oder die Kontaktbuchse des Überwachungsleiters (ÜL) kürzer als die anderen Kontaktstifte auszuführen, sodass die letztgenannten Kontaktstifte und die entsprechenden Kontaktbuchsen nur spannungslos zusammengeführt oder getrennt werden können.Explosion-proof equipment for use in supervised circuits shall be improved so as to simplify the wiring of the equipment and thus be more user-friendly and to enable hot and cold cable decontrol by preventing the occurrence of sparks. DOLLAR A For this enhancement, it is proposed to factory-integrate connectors into the housing and connect them in the enclosure so that the wiring can be made via connectors also provided with connectors that connect to the equipment connectors without the need to open the equipment therefor, Cable must be pulled in, stripped and connected and the equipment must be closed again. DOLLAR A Furthermore, it is proposed to make the contact pin or the contact socket of the monitoring conductor (ÜL) shorter than the other pins, so that the latter pins and the corresponding contact sockets can only be merged or disconnected without tension.
Description
Zur elektrischen Installation in explosionsgefährdeten Bereichen werden unter anderem explosionsgeschützte elektrische Betriebsmittel, insbesondere Leuchten oder Verteilerkästen eingesetzt, die innerhalb überwachter Stromkreise verkabelt werden müssen.to electrical installation in potentially explosive atmospheres are subject to other explosion-proof electrical equipment, in particular lights or distribution boxes used, the within monitored Circuits must be wired.
Bisher erfolgt diese Verkabelung meistens, indem in dem elektrischen Betriebsmittel das Kabel an einer Anschlussklemme angeschlossen wird, durch eine Kabeleinführung am Gehäuse des Betriebsmittels herausgeführt, in die Kabeleinführung des nächsten Betriebsmittels eingeführt und an dessen Anschlussklemme angeschlossen wird, u.s.w.So far This wiring is usually done by putting in the electrical equipment the cable is connected to a terminal, through a cable entry on the housing of the equipment led out, into the cable entry of the next Operating resources introduced and is connected to the terminal, u.s.w.
Das Anschließen ist sehr umständlich und zeitintensiv, da dafür jedes Betriebsmittel geöffnet werden muss, Kabel abisoliert und an den Anschlussklemmen angeschlossen werden müssen und das Betriebsmittel wieder geschlossen werden muss.The Connect is very complicated and time-consuming, because of that every resource will be opened must, stripped cable and connected to the terminals have to be and the equipment must be closed again.

Der Erfindung liegt- das Problem zugrunde, die Verkabelung von explosionsgeschützten Betriebsmitteln zu vereinfachen und die Montagearbeitszeiten zu verkürzen und sicherzustellen, dass beim Zusammenführen oder Trennen von Stecker und Buchse mögliche entstehende Funken nicht zu einer Explosion führen oder das Entstehen von Zündfunken von vornherein unterbunden wird.Of the Invention is the problem underlying the wiring of explosion-proof equipment to simplify and shorten assembly times and Ensure that when merging or disconnecting plug and Socket possible sparks do not cause an explosion or the emergence of spark is prevented from the outset.
Nach der vorliegenden Erfindung wird dieses Problem durch die Merkmale des Anspruchs 1 gelöst. Der Kontaktstift oder die Kontaktbuchse, an dem oder an die der Überwachungsleiter (ÜL) des Stromkreises mit einer unter der Mindestzündspannung liegenden Spannung angeschlossen ist, ist kürzer als die anderen Kontaktstifte. Der Stromkreis wird erst geschlossen, wenn der ÜL-Kontaktstift mit der ÜL-Kontaktbuchse Kontakt bekommt, und zu diesem Zeitpunkt befinden sich alle anderen Kontaktstifte bereits in den entsprechenden Kontaktbuchsen. Umgekehrt wird der Stromkreis bereits unterbrochen, sobald der ÜL-Kontaktstift oder die ÜL-Kontaktbuchse keinen Kontakt mehr mit der ÜL-Kontaktbuchse oder dem ÜL-Kontaktstift hat, sodass alle übrigen Kontakte erst getrennt werden können, wenn sie bereits spannungslos sind. Somit wird durch die verkürzte Ausführung des ÜL-Kontaktstiftes oder der ÜL-Kontaktbuchse unterbunden, dass die anderen Kontakte unter Spannung zusammengeführt oder getrennt werden und Funken entstehen, die eine möglicherweise vorhandene explosive Atmosphäre zünden können.To The present invention addresses this problem by the features of claim 1. Of the Contact pin or the contact socket, on or to which the supervisor (OC) of the Circuit with a voltage below the minimum ignition voltage is connected is shorter than the other pins. The circuit is first closed, if the ÜL contact pin with the ÜL contact socket Get in touch, and at this point all others are Contact pins already in the corresponding contact sockets. Vice versa the circuit is already interrupted as soon as the ÜL contact pin or the ÜL contact socket no Contact more with the ÜL contact socket or the ÜL contact pin, so all the rest Contacts can only be separated if they are already tensionless. Thus, the shortened version of the ÜL contact pin or the ÜL contact socket prevented, that the other contacts merged under tension or be separated and sparks that may be explosive the atmosphere can ignite.
Desweiteren sind Schutzleiter(SL)-Kontaktstifte der Stecker oder die Schutzleiter(SL)-Kontaktbuchsen der Buchsen länger als die anderen Kontaktstifte oder Kontaktbuchsen ausgeführt.Furthermore are protective earth (SL) contact pins of the connectors or the protective conductor (SL) contact sockets the sockets longer than the other pins or contact sockets.
Das Betriebsmittel besitzt mindestens einen von vornherein ins Gehäuse integrierten und verdrahteten Steckverbinder in Flachbauweise, welcher entweder als Buchse oder als Stecker ausgebildet ist. Die Steckverbinder sind entweder fester Bestandteil des Betriebsmittelgehäuses oder nachträglich werksseitig von innen oder außen an dem Betriebsmittelgehäuse befestigt, z.B. angeschraubt. Die Steckverbinder haben eine federnd gelagerte Abdeckklappe, die vor dem Einstecken des Kabels geöffnet werden muss und die durch die Spannkraft der Feder wieder zuschnappt, wenn das Kabel herausgezogen worden ist.The Equipment has at least one integrated into the housing from the outset and wired flat-type connectors, which either is designed as a socket or plug. The connectors are either an integral part of the equipment housing or later factory from the inside or outside on the equipment housing attached, e.g. screwed. The connectors have a springy mounted cover flap, which must be opened before plugging in the cable and snapped back by the tension of the spring when the Cable has been pulled out.
Die Steckverbinderbuchse oder der Steckverbinderstecker des letzten Betriebsmittels am Ende eines Betriebsmittelstranges erhält als Abschluss eine kabellose Buchse oder einen kabellosen Stecker mit integriertem Endglied.The Connector socket or the connector plug of the last Equipment at the end of a resource strand receives as completion a wireless jack or a wireless plug with built-in End link.
Die Überwachung des Stromkreises kann wahlweise durch einen Beleuchtungswächter mit den Bausteinen Isolationsüberwachung, Schutzleiterüberwachung und/oder Strebstillsetzeinrichtung durchgeführt werden.The supervision of the circuit can optionally by a lighting monitor with the modules insulation monitoring, Protective earth monitoring and / or Strebstillsetzeinrichtung be performed.
Ein Ausführungsbeispiel der Erfindung ist in den Zeichnungen am Beispiel von explosionsgeschützten Langfeldleuchten dargestellt und wird im folgenden näher beschrieben.One embodiment The invention is in the drawings using the example of explosion-proof linear luminaires and will be described in more detail below.
