Embodiment
Referring to figs. 1 through Fig. 4 the plug socket of the utility model is described.
Plug socket like Fig. 1 and the utility model shown in Figure 4 comprises plug 200, power line 300 and jack body 100.Be provided with supply module 1 USB module 21 that be connected with at least one, that external equipment is charged in the jack body 100 with supply module.Jack body 100 is provided with the usb 1 01 corresponding with USB module 2.
As shown in Figure 2, supply module 1 comprises: the interchange input rectification circuit 11, high frequency DC converting circuit 12 and the current rectifying and wave filtering circuit 13 that connect successively.Wherein, exchanging input rectification circuit 11 is used for converting the AC energy of input into direct current energy.High frequency DC converting circuit 12 with exchange input rectification circuit 11 and link to each other, high frequency DC converting circuit 12 is used for the direct current after the rectification is carried out step-down.Current rectifying and wave filtering circuit 13 links to each other with USB module 2 with high frequency DC converting circuit 12 respectively.
As shown in Figure 3, high frequency DC converting circuit 12 comprises: transformer T1 and the direct current 300V end 121 and pulsewidth modulated intergrated circuit end 122 that are connected with the two ends of the primary coil of transformer T1 respectively.
Current rectifying and wave filtering circuit 13 comprises: diode D1, inductance L 1 and capacitor C 1.The positive pole of diode D1 is connected with first end of the secondary coil of transformer T1, and the two ends of inductance L 1 are connected with USB module 2 with the negative pole of diode D1 respectively.One end of capacitor C 1 is connected with the negative pole of diode D1, and the other end of capacitor C 1 is connected and ground connection with second end of the secondary coil of transformer T1.
During practical implementation, plug socket can be Europlug, American plug-in unit, English socket and GB socket etc., a plurality of USB modules 2 can be set as required and the corresponding usb 1 01 of a plurality of and USB module 2 is set.
The plug socket of the utility model is owing to have USB module 2 and usb 1 01, and the user can directly charge to external equipments such as MP3 player, MP4 player and mobile phones through the data wire that has USB interface after the energized.Simple, convenient, improved user satisfaction.The problem and the loaded down with trivial details problem of switch computation of waste of energy when having solved through the charging of data wire connection computer.This plug socket cost is lower, can make the plug socket of the USB charging of satisfying different capacity according to requirement of client.
The above is the embodiment of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also are regarded as the protection range of the utility model.
