1. An insertion plug with at least a pair of one blade and another blade to: connect to a terminal of a power source cord; project from a connection surface of an insulating plug case; and be inserted to an outlet connected to a power source, thereby establishing a connection between the power source cord and the power source, the insertion plug comprising:
a rotor fixed around the one blade, and housed freely revolvably in the insulating plug case; a guide unit that: is provided in the insulating plug case; and guides the rotor freely revolvably around an axis that extends in a longitudinal direction of the one blade and within a rotation angle of at least 90 degrees or larger between a first rotation position at which the one blade becomes substantially parallel with the other blade and a second rotation position at which the one blade becomes substantially orthogonal to the other blade; and a positioning unit that positions, at the first rotation position or the second rotation position, the rotor that revolves between the first rotation position and the second rotation position, wherein if the rotor is positioned at the first rotation position, the one blade and the other blade are caused to project from a position of the connection surface at which the one blade and the other blade are freely insertable to an AC power source outlet to connect to a commercial use AC power source, and if the rotor is positioned at the second rotation position, the one blade and the other blade are caused to project from a position of the connection surface at which the one blade and the other blade are freely insertable to a DC power source outlet to connect to a commercial use DC power source. |
