Referring to fig. 2 and 3, fig. 8 and 9, and fig. 2 and 3 respectively show a schematic view when the support frame of the portable power source in fig. 1 rotates to the first position, and a schematic view when the charging connector of the portable power source rotates to a state to be charged. When charging is needed, the charging connector 420 is rotated to extend out of the extending slot 114, and is in the state shown in fig. 3, and is inserted into a charging port of the electronic device. After the charging is completed, the charging connector 420 is rotated in the reverse direction to be accommodated in the protruding slot 114, and is in the state shown in fig. 2.

The connector portion 421 and the printed circuit board 300 are both located on the same side of the main body portion 422, for example, in the view of fig. 5, the connector portion 421 and the printed circuit board 300 are both located on the left side of the main body portion 422, and the battery cell 200 is located on the right side of the main body portion 422. One end of the flexible circuit board 500 is electrically connected to the main body portion 422, and the other end is electrically connected to the printed circuit board 300.

When charging connector 420 is in the state shown in fig. 3, flexible circuit board 500 is curled, and when charging connector 420 is in the state shown in fig. 8, flexible circuit board 500 is stretched.

After one end of the flexible circuit board 500 is connected to the end of the main body 422, the flexible circuit board is bent downward to the lower side of the charging connector 420 and extends to the printed circuit board 300. Although the flexible printed circuit board 500 may be connected to other positions of the charging connector 420, the length of the flexible printed circuit board 500 may be made larger when the flexible printed circuit board is arranged as described above. When the charging connector 420 rotates relative to the connecting frame 410, the flexible circuit board 500 can be curled to a greater extent, the obstruction to the rotation of the charging connector 420 is smaller, and the free rotation of the charging connector can be ensured.

The through groove 4121 is disposed to limit and guide the flexible circuit board 500, and when the charging connector 420 rotates, the flexible circuit board 500 passes through the through groove 4121 to be curled or stretched, so as to avoid a messy shape when the flexible circuit board is curled. However, unlike the aforementioned structure, when charging connector 420 is in the state shown in fig. 3, flexible circuit board 500 is stretched, and when charging connector 420 is in the state shown in fig. 10, flexible circuit board 500 is curled.
