Explosion-proof electrical equipment items, in particular light and distributor boxes, in the monitored electrical circuits with plug connections

摘要

Explosion-proof equipment for use in monitored circuits are intended to be improved in such a way that the cabling of the operating medium is simplified and hence is more easily serviced and the - and entkabeln during operation by means of preventing the creation of ignition sparks is made possible.For this improvement, it is proposed that at the factory a plug connector in the housing and to connect to integrate in the housing, so that the cabling likewise via cables provided with plug-in connectors can be effected with the plug connectors of the resources are connected, without the operating medium must be opened for this purpose, cables, have to be stripped and connected, and the operating medium must be closed again.Furthermore, it is proposed that the contact pin or the female contact of the monitoring conductor (ul) is shorter than the other contact pins, so that the latter contact pins and the corresponding contact sockets only can be brought together or separated from the voltage.
