Abstract:
An explosion-proof arrangement (20) having a bushing part (23) with a bushing opening (24) that defines a bushing surface (25) and a structural unit (29) arranged in the bushing opening (24). The structural unit (29) includes a deformable inner body (31) with at least one conductor channel (32) extending through in a longitudinal direction (L), and a plastically deformable connecting sleeve (30) surrounding the inner body (31). At least one conductor (21) is guided through its own associated conductor channel (32) in the inner body (31). A connecting portion (33) of the connecting sleeve (30) is plastically deformed so that it presses radially inwardly on the inner body (31) and deforms it in a radial direction (R). A first delimiting surface (35) is formed on an outer circumference of the plastically deformed connecting portion (33). The bushing surface (25) forms a second delimiting surface (36). By arranging the structural unit (29) with the first delimiting surface (35) in the bushing opening (24), a flameproof Ex gap (37) is produced between the two delimiting surfaces (35, 36).
