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