Abstract
An explosion-proof assembly () is provided for guiding at least one conductor device () through a wall without ignition transmission. The assembly () has at least one bushing part () arranged in the wall having one or more bushing openings, each of which is delimited in the circumferential direction by a bushing surface. A connecting body () is associated with each conductor device () coaxially surrounds a mounting portion of the conductor device () in a flamegap-free connection. The connecting body () has a first outer delimiting surface and the bushing opening defines a second delimiting surface. A flameproof Ex gap () is formed between the two delimiting surfaces by at least partial insertion of the connecting body () into the bushing opening. Bushing openings without a connecting body () are closed in a flameproof manner by a closure member (). A securing device () secures the connecting body () in the bushing opening ().
