The invention relates to a power plug with neutral wire leakage protection. The power plug comprises a base, a plug assembly, a leakage protection device and an upper cover. The plug assembly comprises a plug body and a plug matched with a supply socket, the plug is embedded on a lower end face of the plug body, upper surface of the plug body is provided with two fixed legs which are arranged in the reverse V-shape, free ends of the two fixed legs respectively extend along with an axial direction of the plug body to form an extension part, the extension part is respectively provided with through holes along with the axial direction, the lower end face of the plug body is also respectively provided with elastic sheet metal which is eclectically connected with the plug, the plug body runs through the base from top to bottom, and a firm screw sequentially passes through the base and the thorough holes on the extension part of the plug body, and then fixed on the leakage protection device. The power plug with neutral wire leakage protection greatly improves adaptability of the power plug as the plug on the plug assembly can be very conveniently replaced so as to adapt to British, American, European and Chinese supply outlet systems.
Description
technical field [0001] The invention relates to a power plug, in particular to a power plug with neutral line leakage protection. Background technique [0002] The existing electric leakage protection power plug has the function of electric leakage protection and can effectively prevent personal electric shock, so it is widely used. [0003] Power plugs with leakage protection function are generally used in humid environments, such as swimming pools, shower rooms, kitchens, toilets, etc. With the development of science and technology, power plugs with leakage protection are becoming more and more high-performance, high-sensitivity, multi-adaptive and multi-functional The direction of protection is developing. The existing leakage protection power plugs are generally simple in structure, low in sensitivity and poor in protection performance. Especially the plug part, in order to ensure the safety of use, the plug part is generally cast as one with the base, so that the power...
