Through adopting technique scheme; The utility model has following beneficial effect at least: through at power supply adaptor set inside rechargeable battery; And corresponding charging and charge/discharge control circuit are set, thus can connect civil power, when corresponding electronic products being supplied power the inner rechargeable battery charging of adapter as the adapter of routine; In the time can't connecting civil power; Can be the electronic product power supply/charge by this rechargeable battery, no matter at home, travel, go on business, can ensure effectively that all electricity consumption products such as mobile phone, MP3, PSP game machine have sufficient power supply to use at any time.
Description of drawings
Fig. 1 is the decomposing schematic representation of the utility model power supply adaptor.
Fig. 2 is the plug decomposing schematic representation of the utility model power supply adaptor.
Embodiment
Please refer to an embodiment of Fig. 1 and the utility model shown in Figure 2; The utility model provides a kind of power supply adaptor, comprises housing 1, is located at pcb board 2 in the housing 1 with in the plug 3 that is used for being plugged to electricity network of being located at housing 1 one sides, the power supply port 4 that links to each other with pcb board 2 and be located in the said housing and the rechargeable battery 5 that is electrically connected with pcb board 2.
Said housing 1 is fastened with lower casing 12 by upper casing 10 and forms.And on the said pcb board 2 except the essential circuit of adapters such as the AC-DC change-over circuit of routine, transforming circuit, also be provided with charging and charge/discharge control circuit that control rechargeable battery 5 discharges and recharges.Also can be provided with protective circuit on the said pcb board, this protective circuit has overvoltage, cross put, multiple protection functions such as overcurrent, excess temperature, short circuit.
Preferably, said rechargeable battery 5 is a polymer Li-ion battery, has the big characteristics of volume low capacity.
Preferably, said plug 3 is sides that are slidedly arranged on housing 1 removably.For ease of the said plug 3 of slidingly assemble removably; Side at housing 1 is provided with slide rail 14; Slide rail 14 be provided with first contact flat spring 16,18; Be provided with plug guide pin bushing 30 and state plug 3, institute's plug guide pin bushing 30 1 sides are provided with the chute 300 that is complementary with slide rail 14, and said plug 3 cooperates with slide rail 14 through said chute 300 and is located at slidably on the said guide rail 14.Be provided with in the plug 3 and the pin of plug 3 31,32 corresponding second contact flat springs 34,36 that link to each other, and said second contact flat spring 34,36 has and is convexly set in the said chute 300, is used for the elasticity abutting part 340,360 with corresponding first contact flat spring, 16,18 elasticity butts.Because plug 3 can be pulled down, and changes the plug of country variant standard easily, for example: Chinese national standard plug, U.S. mark plug, Europe superscript plug etc., variant country uses in the world thereby can satisfy.
