  • Patent number: 9702536
    Abstract: An explosion-proof lamp cable gland is disposed in a channel of a coupling portion of an explosion-proof lamp for a cable to pass through, and includes a first explosion-proof member disposed at one end of the channel remote from an opening of the coupling portion and a compact member disposed at another end of the channel close to the opening of the coupling portion to connect to the first explosion-proof member. The explosion-proof lamp cable gland of the invention thus formed is simpler in structure and smaller in size, and can achieve explosion-proof effect as a conventional connector that is bulkier in size. Thus not only the cost is lower, but serial connection among the explosion-proof lamps also can be accomplished easily to make application versatile.
