FASTENING DEVICES FOR EXPLOSION-PROOF ENCLOSURES

摘要

An enclosure can include a top enclosure portion having a top flange and a first top engagement feature. The enclosure can also include a bottom enclosure portion mechanically coupled to the top enclosure portion, where the bottom enclosure portion has a bottom flange that mechanically couples to the top flange and a first bottom engagement feature that mechanically couples to the first top engagement feature. The enclosure can further include a first fastening device mechanically and movably coupled to the first top engagement feature and the first bottom engagement feature. The first fastening device, in an engaged position, can maintain a flame path between the top flange and the bottom flange. The first fastening device, in a disengaged position, can fail to maintain a flame path between the top flange and the bottom flange.
