Abstract
A cable-winding charger includes a housing, a main circuit board, a plug, a pivot base, a torsion spring, and a data cable. The main circuit board is in the housing and includes conductive rings. The conductive rings are coaxially arranged around the column of the housing. The plug is pivotally connected to the housing and electrically connected to the main circuit board. The pivot base is pivotally connected to the housing. Each conductive piece of the pivot base contacts the corresponding conductive ring. One end of the torsion spring is fixed to the column, and the other end of the torsion spring is fixed to the pivot base. One end of the cable body of the data cable is electrically connected to the conductive pieces, and the other end of the cable body is electrically connected to the connection port.
