20080252255 | CHARGER WITH INPUT AND OUTPUT VOLTAGES ADJUSTABLE BY MEANS OF SINGLE CIRCUIT MATED PLUG-IN CARD TYPE SWITCH - The present invention provides a charger whose input and output voltages are adjusted by means of a single circuit mated plug-in card type switches, in particular relates to a charger that is suited for various input voltages adjusted by various plug-in cards to achieve charging, which has a function of adjusting output voltages by means of plug-in card-type switches to securely and properly charge various electronic terminals having various rated voltages, and whose voltages are universally used for charging electronic terminals. The charger is characterized by comprising a charger body, a DC input and output jack and a slot on one side of the charger body; a circuit main board, N battery packs and a display circuit built in the charger body; a plurality of plug-in cards and a plurality of DC input converters, or a plurality of plug-in cards and a plurality of DC output converters, mated with the DC input and output jack and the slot, and plug type DC jacks arranged at one end of the plurality of DC input converters and the plurality of DC output converters respectively; and a external power source and output wires connected to the plug type DC jacks respectively. The external power source is input into the built in electronic circuit through the plurality of input converters and the plurality of input plug-in cards, so that the input charging current can be adjust to charge the battery packs, and there also are electronic circuit arranged in the plurality of output plug-in cards, so that output voltage can be adjusted by changing values of electronic parts to satisfy the charging requirement of electronic terminals. | 10-16-2008 |
