EXPLOSION PROOF TYPE TERMINATION CONNECTION BOX

摘要

The present invention relates to an explosion proof type termination connection box. The explosion proof type termination connection box according to the present invention includes: an upper cover which is penetrated by a conductor withdrawal bar to expose the conductor; a porcelain tube which is connected to the upper cover to form an external wall, and receives a cable which is electrically connected to the conductor withdrawal bar; a stress cone which is formed along the outer surface of the cable in the porcelain tube and relaxes electric field concentration; a lower hinge which supports the lower part of the porcelain tube and is penetrated by the cable; and a support insulator which supports the lower hinge; and at least two discharge parts which discharge an internal pressure when the internal pressure of a space formed by the upper cover, the porcelain tube, and the lower hinge, is higher than a preset reference pressure.
