摘要： An explosion-proof pressure-tight housing for electrical operating device has a rigid lower shell and an elastic upper shell terminating the lower shell in the manner of a cover, wherein the lower shell includes a base, preferably formed as a rounded rectangle, and also includes side walls, the outer surfaces of which are inclined inwardly by an acute angle, where the elastic upper shell has a cover base and side walls, which are splayed outwardly at the angle, the inside width of the upper shell is smaller than the outside width of the lower shell, and the upper shell is pressed with the lower shell such that a flameproof gap is formed between the side walls of the upper shell and the side walls of the lower shell.
