Title: EXPLOSION-PROOF ARRANGEMENT AND METHOD FOR PRODUCING SAME
Abstract:
The invention relates to an explosion-proof arrangement (20) which is designed to lead at least one line device (21) through a wall without an ignition flame. The arrangement (20) has at least one passage part (24) having at least one passage opening (48) which is bounded by a passage surface (49) in the circumferential direction. The at least one passage part (24) is designed to be arranged in the wall. Each passage opening (48) has an associated connecting body (23) through which at least one line channel (29) passes. A conductor (22) extends through the line channel (29). The connecting body (23) has a connecting section (30) which is connected to the conductor (22) in a force-fitting and/or interlocking manner by plastic deformation. A first boundary surface (32) is formed on the plastically deformed connecting section (30). The passage surface (49) constitutes a second boundary surface (33). An ignition flame-proof path (34) is formed between the two boundary surfaces (32, 33) by inserting the connecting section (30) into the passage opening (48).
