Description
Deckelgehäuse für elektrische Einrichtungen In schlagwetter- und explosionsgefährdeten Räumen müssen Geräte, an denen betriebsmäßig Funken auftreten, druckfest gekapselt sein. Bei anderen, nichtfunkenden elektrischen Einrichtungen ist dagegen eine einfache Kapselung zulässig. Wenn nun elektrische Einrichtungen beider Arten in .einer Anlage zusammen verwendet werden sollen, so müssen entweder beide druckfest gekapselt werden, oder es müssen getrennte Gehäuse vorgesehen werden.Cover housing for electrical equipment in firedamp and explosion endangered areas In rooms, devices where sparks occur during operation must be encapsulated in a pressure-tight manner be. In the case of other, non-sparking electrical devices, on the other hand, a simple one is used Encapsulation permitted. If now electrical equipment of both types in one system are to be used together, either both must be encapsulated in a pressure-tight manner, or separate housings must be provided.
Gemäß der Erfindung ergibt sich eine Vereinfachung sowie eine Ersparnis an Platz, Werkstoff und Kosten dadurch, daß der Dekkel eines nicht druckfesten Gehäuses auf seiner Innenseite als druckfestes Gehäuse zur Aufnahme von Schaltgeräten, wie Schalter, Schütze, Relais, Sicherungen u. d-1., ausgebildet wird.According to the invention, there is a simplification and a saving in terms of space, material and costs in that the lid of a non-pressure-resistant housing on its inside as a pressure-resistant housing to accommodate switching devices such as Switches, contactors, relays, fuses and the like.
Ein Ausführungsbeispiel zeigen die Abb. i und 2, und zwar Abb. i in Vorderansicht, Abb. 2 im Schnitt in einer dazu senkrechten Ebene.An embodiment is shown in Figs. I and 2, namely Fig. I in Front view, Fig. 2 in section in a plane perpendicular thereto.
Der Unterkasten i eines nicht druckfesten Gehäuses für eine Kreuzdose enthält im Inneren Verteilungsklemmen 2. Durch einen Scharnierdeckel .4 ist das Gehäuse mittels einer Dreikantschraube 3 verschließbar. Aus der Innenseite des Deckels sind vier Seitenwände 8 hochgezogen, die mit Dichtungsflanschen 12 versehen sind. Mit diesen ist die Rückwand 9 des druckfesten Gehäuses mittels der Schrauben ii druckfest verschraubt.The lower box i of a non-pressure-resistant housing for a junction box contains distribution terminals inside 2. Through a hinge cover .4 this is Housing can be closed by means of a triangular screw 3. From the inside of the lid four side walls 8, which are provided with sealing flanges 12, are raised. With these the rear wall 9 of the pressure-resistant housing is by means of the screws ii screwed pressure-tight.
In dem druckfesten Gehäuse ist ein Schwenktastschalter 7 eingebaut, dessen Achse 6 druckfest durch die Vorderwand des Deckels hindurchgeführt ist und von vorn mittels des Schwenkgriffes 5 betätigt werden kann. Die Leitungsdurchführungen i o sind durch eine oder mehrere Seitenwände des druckfesten Gehäuses hindurchgeführt.A toggle switch 7 is built into the flameproof housing, whose axis 6 is passed through the front wall of the cover in a pressure-proof manner and can be operated from the front by means of the swivel handle 5. The cable bushings i o are passed through one or more side walls of the pressure-resistant housing.
An Stelle des Schalters 7 können auch irgendwelche anderen druckfest zu kapselnden Geräte eingebaut sein.Instead of the switch 7, any other pressure-proof can also be used devices to be encapsulated.
