Title: EXPLOSION-PROOF ASSEMBLY AND METHOD FOR PRODUCING SAME
Abstract:
The invention relates to an explosion-proof assembly (20) which is designed to guide at least one line device (21) through a wall without the break-through of a flame. The assembly (20) has at least one guide-through part (24) with one or multiple guide-through openings, each of which is delimited in the circumferential direction by a guide-through surface. The at least one guide-through part (24) is designed to be arranged in the wall. A connecting element (23) is assigned to each line device (21) and coaxially surrounds the line device (21) in an attachment section by forming an spark gap-free connection. The connecting element (23) has a first boundary surface. The guide-through surface represents a second boundary surface. A flame-proof Ex gap (34) is formed between the two boundary surfaces by the at least partial insertion of the connecting element (23) into the guide-through opening. The guide-through openings of the guide-through part (24), in which no connecting element (23) is arranged without a spark gap, are sealed in a flame-proof manner by a sealing means (70). A securing device (52) secures the connecting elements (23) in the guide-through opening (48).
