Patent ID: 11374390

Abstract:
The invention relates to an explosion-proof assembly (20) designed to guide at least one conductor device (21) through a wall in a flameproof manner. The assembly (20) has a bushing part (24) with a bushing opening (48) having a bushing surface (49). The bushing part (24) is arranged in the wall. The bushing opening (48) has an associated connecting body (23) with at least one conductor channel (29) through which a conductor device (21) extends. The connecting body (23) has a connecting portion (30), which is connected to the conductor (22) in a frictionally engaged and/or form-fitting manner by plastic deformation. A first delimiting surface (32) is formed on the plastically deformed connecting portion (30), and the bushing surface (49) defines a second delimiting surface (33). A flameproof Ex gap (34) is formed between the two delimiting surfaces (32, 33) by inserting the connecting portion (30) into the bushing opening (48).
