Abstract
A housing for receiving an electronic device in an explosive atmosphere may include a first housing part and second housing part coupled to one another via at least one screw connection defining a housing interior for receiving the electronic device. The screw connection may include a screw and a separate threaded pin. A recess may be defined in first housing part. A first threaded bush may be arranged in the recess for receiving the screw. A through-opening may be defined in the second housing part concentric to the recess and a second threaded bush may be arranged in the through-opening for partially receiving the screw and the threaded pin. The screw may be arranged in the through-opening and screwed into the first threaded bush coupling the first housing part and the second housing part to one another. The threaded pin may be screwed into the second threaded bush.
