Friction between metal objects may generate static electricity, and static electricity discharge may generate electric sparks, causing accidents. Therefore, explosion-proof places require anti-static measures. When using a plug positioning structure in explosion-proof places, the plug positioning structure uses strong and pressure-resistant metal objects. During use, the plug positioning structure is prone to collision and friction, and when static electricity accumulates, a discharge phenomenon will occur, detonating combustibles. To avoid these situations, the common practice is to connect a conductive device (such as an iron chain) to the metal object, and the conductive device is grounded to prevent static electricity accumulation, but it is rather troublesome.
