摘要： An explosion-proof electrical apparatus comprises two enclosures containing electrical devices. The enclosures are physically interconnected by a one-piece or two-piece hollow sleeve member which is screwed into threaded holes of the enclosures. A fitting assembly mounted in the sleeve member comprises a hollow feedthrough bushing screwed into the sleeve member, a hollow feedthrough seal member screwed into the feedthrough bushing, and a plurality of conductors extending through the feedthrough seal member and electrically connected to the electrical devices. The conductors are embedded in sealing compound which occupies the feedthrough seal member. During assembly of the fitting assembly, the feedthrough seal member is positioned within the sleeve, and the feedthrough bushing is screwed along the feedthrough seal member and is simultaneously screwed into the sleeve.
