Patent ID: 7646577

Claim:
A power plugging device for releasing charges from electric surges comprising a housing ( 13 ); a circuit board ( 14 ) having a plurality of electric elements ( 141 ) and being inlaid into the housing ( 13 ); a medium layer ( 12 ) formed with a base ( 16 ); the medium layer ( 12 ) being formed with a plugging aperture ( 121 ); a receiving component ( 17 ) formed in the medium layer ( 12 ); and the receiving component ( 17 ) having a predetermined indentation ( 171 ); a pair of the oblique-flat-blade plugging terminals ( 11 ) extended from a lower side of the medium layer ( 12 ); upper ends of the plugging terminals ( 11 ) being wrapped within the receiving component ( 17 ); a pair of oblique-flat-blade terminal ends ( 18 ) being received in the receiving component ( 17 ); each terminal end ( 18 ) having a discharging tip ( 181 ); the two discharging tips ( 181 ) being arranged so that the two discharging tips ( 181 ) point to one another; a cover ( 15 ) propping up the circuit board ( 14 ) and covering the medium layer ( 12 ) formed with the base ( 16 ); a shape of the cover ( 15 ) being similar to a triangle so as to match the design of the oblique-flat-blades type plugging terminals ( 11 ); the cover ( 15 ) comprising a tenon ( 151 ) which can be aligned to and buckled with the plugging aperture ( 121 ) of the medium layer ( 12 ); the cover ( 15 ) having an electric discharging hole ( 152 ) at center portion thereof; wherein the cover ( 15 ) covers upon the receiving component ( 17 ); the electric discharging hole ( 152 ) of the cover ( 15 ) is aligning to the center of the indentation ( 171 ); wherein the receiving component ( 17 ) includes three areas; a first area ( 17 a ) serves for receiving the plugging terminals ( 11 ); a symmetric second area is located next to the first area ( 17 a ) for receiving the end portions ( 18 ) and allowing the terminal ends ( 18 ) to be electrically connected with the plugging terminals ( 11 ); a third area ( 17 c ) is formed with the indentation ( 171 ); and wherein discharging tips ( 181 ) of the terminals ( 18 ) exposes from the indentation ( 171 ) and opposite to each other for a certain distance; and the terminals ( 18 ) being naked within the indentation ( 171 ) and being capable of executing a point discharging while a spike occurs.
