In the utility model registration Application of Jitsugantaira 3-50974, received plug when in AC power plugs and sockets of the JIS, the blade of the attachment plug projecting the blade of metal, to elaborate the difference to the root of the blade receiving the plug receiving of around the blade receiving and Tsute disconnecting grip hands of the attachment plug, the cord contact portion main body was Kutsugaetsu with an insulator, by providing larger holes than the area of ​​the contact surface of the plug receiving and absolute of attachment plug to obscure a portion of the insertion tip of the body of the green product, during insertion, after insertion, the electric leakage and electric shock can be prevented, it has been claimed hole for causing a buried, protruding the blade metal from the hole to Tsute insertion and removal grip in the hands of the attachment plug, absolute green products in Kutsugaetsu was code contact part body itself is large, when the blade of metal does n

(57) [summary] [purpose] flat bar two protruding are the type of outlet plug body itself of metal, without entering larger than the hole in order to bury the electrical outlet plug body of usually of the same type, of metal Even if the flat two rods does not turn on until the root, flat metal rod that [construction] electricity demand to a stable demand to ensure electricity in the hole is larger than the plug body from the hole is projecting two type of outlet plug body itself there are, if the flat bar of two metal larger than the hole of the insertion portion to be buried the plug body itself usually of the same type does not turn on until the root, do not fall into the hole and the hole between the insertion body, the outlet plug and Hisakomi body of the same type that becomes the lid to fill the hole provided, and plug it into the hole, by plugging the outlet plug body of the same type that do not fall into the hole to the lid , it is possible to demand an electricity certainly more stable than the hole. It claims the outlet plug and Hisakomi body of the same type that becomes the lid to fill the hole. The size of the insertion and the insertion body itself isomorphic to a lid for filling the hole, the shape is assumed to stable without possible loose if you plug the holes.
