detailed description

The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

Referring to Figures 1 to 3, the portable charger of the present invention includes a first component 1 and a second component 2. The first component 1 is provided with a first insulative housing 11 , and the first insulative housing 11 is provided with a high voltage circuit and a USB male port 12 electrically connected to the high voltage circuit. The first insulative housing 11 is movably connected, and the USB male port 12 extends outside the first insulative housing 1 1 and can be received in the first insulative housing 1 1 .

A first fastening post 111 and a first fastening slot 112 are respectively disposed on the two sides of the USB insulative housing 12, and a cross-sectional area of the free end of the first fastening post 111 It is larger than the cross-sectional area of the middle of the first fastening post 111. The width of one end of the first fastening groove 112 away from the notch is larger than the width of the notch. One end of the first insulating housing 1 1 is provided with a first through hole 13 13 so that the first insulating housing 11 forms a hangable hanging piece. The first component 1 is connected to a plug electrically connected to the high voltage circuit, the plug is provided with two pins, and the plug is rotatable and received in the first insulating housing, so that the pin can be received in the The first insulating housing 1 1 is described.

The second component 2 is provided with a second insulative housing 21, and the second insulative housing 21 is provided with a low voltage circuit and a USB female port 22 and a charging socket 23 electrically connected to the low voltage circuit. The USB female port 22 is corresponding to the position of the USB male port 12, and the second insulating housing 21 is disposed on the two sides of the USB female port 22 with a second fastening post 211 and a second fastening slot 212 respectively. , The second fastening post 211 and the second fastening slot 212 are opposite to the first fastening post 1 11 and the first fastening slot 112 respectively.
