<p>PROBLEM TO BE SOLVED: To provide a plug conversion adapter that can open a shutter with ease even for a BF type AC power receptacle and that can be used for the other type AC power receptacle.SOLUTION: Since a gap between a pair of electrode pins 1A and 1B can be adjusted by operating a pair of first movable members 5A and 5B, a plug conversion adapter can be used for many types of AC power receptacles. Since a gap between the first movable members 5A and 5B is restricted to the maximum by a second movable member 3, a shutter can be opened with ease even for an AC power receptacle having such a structure that the shutter is opened by pressing both corners of an insertion port for the pair of electrode pins.</p> |
