USB port 61 is 2100mA and 4200mA respectively. Compared with electrical components with small output current from theUSB port 61, the IC chip 69, thetransformer 64, the twocapacitors 68, theword inductor 67, thecommon mode inductor 66, theY capacitor 62 and theX capacitor 65 in this embodiment are lager in terms of size and power, and the distance between a high voltage circuit and a low voltage circuit is more than 6mm. Thus, in this embodiment, the internal structure of the wall outlet needs to be better arranged in order to provide enough space for these electrical components. - As shown in
Fig. 5 , if the prefabricated cylinder inside the wall for installing the electric wall socket is not deep enough, causing thepanel 10 of the wall outlet to protrude from a wall too much and the backside surface of thepanel 10 cannot contact surface of the wall, apad frame 80 can be added between thepanel 10 and the mountingrack 20 to fill in the gap between thepanel 10 and the wall, so as to adapt the depth of the prefabricated cylinder inside the wall. -

panel 10 and thebottom cover 70 provides the USB charging device, the live wiremetallic strip 51, the null wiremetallic strip 52 and the earth wiremetallic strip 53. The USB charging device comprises the USB charging circuit board and twoUSB ports 61. The twoUSB ports 61 correspond to the location of the twoUSB charging sockets 12 of thepanel 10 respectively. - Given the reason that the center of the
power slot 11 deviates from the center of thepanel 10 towards the lower end, the live wiremetallic strip 51, the null wiremetallic strip 52 and the earth wiremetallic strip 53 are all moved downwards, thus space is saved above the live wiremetallic strip 51, the null wiremetallic strip 52 and the earth wiremetallic strip 53. - As shown in
Fig. 8 , aUSB bracket 30 is provided on top of the earth wiremetallic strip 53, appearing in "II" shape overall.
