Abstract
An explosion-proof connector (1) comprises a plug part (2) and a socket part (3), the plug part (2) comprising a plug housing (4) with at least two plug pins (6) arranged in a plug insert (5), and the socket part (3) comprising a socket housing (7) with matching socket contacts (9) arranged in a socket insert (8).In order to simplify such an explosion-proof connector in a way that it can be handled more easily especially when disconnecting plug part and socket part while maintaining explosion proofness, one housing (4, 7) comprises an outer sleeve (10) which is detachably connectable to the other housing (7, 4), a first gap (11) being formed between outer sleeve (10) and other housing (7, 4) and a second gap (12) between outer sleeve (10) and associated insert (4, 8) already before electrically contacting plug pins (6) and socket contacts (9) for realizing type of protection d, flameproof enclosure, and type of protection e, increased safety, respectively.
