ABSTRACT:
An explosion-protected modular housing (3) for electrical and/or electronic components (29) includes at least one sand-filled chamber (28), in which the components are housed. The components (29) are protected in this manner in the safety mode known as "sand filling". Also provided on the housing (3) are connection devices (6, 7) for supply lines to the housing. To enable insertion or removal of a selected housing from a holder (2) at any time without shutting off the entire system of which the selected housing (3) is a part, the connection devices (5, 7) are part of a complementary two-part plug-and-receptacle arrangement (4), which is flame-proof. One part (6) of the arrangement is connected electrically with the components (29) in the housing (3), the other part (5) to a power distribution bus. The "not intrinsically safe" circuits are connected via this plug-and-receptacle arrangement (4). Serially connected encapsulated switch means (58, 67) operated upon coupling/uncoupling of the two parts (5, 6) prevent arcing at the plug-and-receptacle arrangement.
