Claims

[Claims for Utility Model Registration] (1) A case with a built-in power supply circuit and a pair of socket terminals connected to the input end of the power supply circuit facing one side, and a case with a pair of socket terminals connected to the input end of the power supply circuit facing the socket terminal on one side of the case; at least two removably attached
The two types of plug bodies have one end of a pair of plug terminals connected to the socket terminal in a common shape, and the other end has a shape that meets the requirements of the AC power source. A power plug adapter characterized by having different shapes depending on the user's needs. (2) The case includes a rectifier circuit consisting of a diode bridge, a capacitor circuit consisting of a series connection of at least two capacitors connected between the rectified output, and the center point of the capacitor circuit and the input terminal of the rectifier circuit. 2. The power plug adapter according to claim (1), which is a registered utility model, and is characterized in that it has a built-in switching means for alternately switching between one of the AC power source and the AC power source. (3) The power plug adapter according to claim 2, wherein the switching means is switched by inserting the plug holding member into the case.
