Abstract
Description
Schlagwettersichere Steckvorrichtung In Bergwerkbetrieben müssen zwecks Vermeidung von Schlagwetterexplosionen die elektrischen Schaltvorrichtungen und Maschinen derart ausgebildet sein, daß die beim Schalten entstehenden Funken mit der Außenluft nicht in Berührung kommen können. Anschlußstecker müssen, um schlagwettersicher zu sein und Funkenbildung zu *rmeiden, mit einem besonderen Schalter ersehen sein. Das Gehäuse für diese Schalter muß entsprechend dicke Wände von genügender Druckfestigkeit besitzen, um den im Innern entstehenden Explosionen Widerstand zu bieten.Fire-weather-proof plug-in device In mines, for the purpose of Avoiding firedamp explosions the electrical switching devices and Machines be designed in such a way that the sparks produced when switching are also used cannot come into contact with the outside air. Connector plugs must be firedamp proof and to avoid sparking, be seen with a special switch. The housing for these switches must have correspondingly thick walls with sufficient pressure resistance to offer resistance to the explosions occurring inside.
Die Erfindung betrifft einen schlagwettersicheren Stecker, bei 'dem weder ein besonderer Schalter noch eine' besondere- Ausbildung des Gehäuses erforderlich ist. Nach der Erfindung wird ein Stecker, durch den in an sich bekannter Weise die Übertragung von der Speiseleitung zu der Verbraucherleitung mittels eines eingebauten Transformators auf induktivem Wege erfolgt, aus zwei Gehäusehälften bestehend ausgebildet, von denen jede Hälfte eine Magnetjochhälfte und eine Transformatorwicklung enthält. Beim Verbinden oder Trennen der Gehäusehälften wird der Eisenweg des Transformators geschlossen oder unterbrochen und damit die Verbraucherleitung unter Spannung gesetzt oder spannungslos gemacht, ohne den sonst beim Ein- und Ausschalten durch Schließen und Öffnen des Stromkreises unvermeidlichen Funken zu ziehen.The invention relates to a firedamp proof plug in which neither a special switch nor a 'special training of the housing required is. According to the invention, a connector through which in a known manner the Transmission from the feed line to the consumer line by means of a built-in Transformer is carried out inductively, formed from two housing halves, each half of which contains a magnetic yoke half and a transformer winding. When connecting or disconnecting the housing halves, the iron path of the transformer becomes closed or interrupted and thus the consumer line is energized or de-energized, without the otherwise when switching on and off by closing and opening the circuit to draw inevitable sparks.
Mit der Steckvorrichtung gemäß der Erfindung ist gleichzeitig der Vorteil verbunden, daß die Verbrauchsleitung die gleiche Spannung haben kann wie die Speiseleitung, daß sie aber auch verschiedene Spannungen haben können. Die Verbindung der Gehäusehälften erfolgt in bekannter Weise, z. B. durch Reibungs-, Bajonettverbindung o. dgl.With the connector according to the invention is at the same time Advantage connected that the consumption line can have the same voltage as the feed line, but that they can also have different voltages. The connection the housing halves are carried out in a known manner, for. B. by friction, bayonet connection or the like
Die Erfindung ist in der Zeichnung in einem Ausführungsbeispiel dargestellt. Innerhalb der beiden Steckergehäuse 2 und 3 befindet sich ein Transformator, dessen Magnetjoch aus zwei Teilen 6 und 7 besteht. Dieser Transformator stellt eine Verbindung zwischen dem Netz q. und der Verbrauchsleitung 5 dar. In geschlossenem Zustande des Steckers liegen die Schenkel 6 und 7 des Magnetjochs fest aufeinander, so daß der Eisenweg geschlossen ist. Soll die Verbrauchsleitung abgeschaltet werden, so werden die Steckerhälften r und 2 und damit auch die Schenkel 6 und 7 getrennt. Durch diese Unterbrechung .des Eisenweges des Magnetjochs wird die Kupplung zwischen Netz und Verbraucher funkenlos aufgehoben.The invention is shown in the drawing in an exemplary embodiment. Inside the two connector housings 2 and 3 there is a transformer whose Magnet yoke consists of two parts 6 and 7. This transformer makes a connection between the network q. and the consumption line 5. In the closed state of the plug, the legs 6 and 7 of the magnet yoke lie firmly on top of one another, so that the iron road is closed. If the consumption line is to be switched off, so the connector halves r and 2 and thus also the legs 6 and 7 are separated. Through this interruption of the iron path of the magnet yoke, the coupling between Network and consumers are lifted without a spark.
