Claims

[Scope of Claim for Utility Model Registration] A through screw hole with a female thread provided in a container wall of a flameproof explosion-proof electric device, the through screw hole, and a through screw hole provided inside the container wall so as to close the through screw hole. a battery storage plug having a battery side terminal and a battery side terminal having a cavity inside which can accommodate a battery and an external male screw that can be screwed into the through screw hole; When the battery storage plug "is attached to or removed from the hole, at the time when the circuit side contact of the circuit side terminal and the battery side contact of the battery side terminal start contacting or separating, the female thread of the through screw hole and the male screw of the battery storage plug and the number of threads of the screw fit are greater than or equal to the values necessary to maintain the explosion-proof property of the electrical equipment. A battery storage mechanism for a pressure-resistant and explosion-proof electrical device, characterized in that the battery-side contactor is disposed therein.
