A kind of Portable power source
Technical field
The utility model relates to the equipment that mobile terminal device is carried out to interim electric power supply, particularly a kind of Portable power source.
Background technology
For the user who improves the mobile terminal devices such as smart mobile phone experiences, these mobile terminal devices towards the future development of height configuration, multi-functional, large-screen, cause the electric quantity consumption of battery significantly to increase just day by day thus.Mobile terminal device is difficult to support for a long time product to use from the electric weight of charged pool usually, brings impact to the use of product.The appearance of portable power source, make the user also not worry that out of doors mobile terminal device does not have electricity, portable power source itself can storage of electrical energy, when the mobile terminal device power shortage portable power source can be easily, in time to being charged from charged pool of mobile terminal device, met people's demand.
Portable power source, comprise the power supply body at present, the storage battery, circuit board and the USB socket that in the power supply body, arrange, and USB socket is connected with circuit board, by USB socket, outwards exports electric weight.The cable that USB plug is set by two ends is connected portable power source with mobile terminal device, can realize the charging to mobile terminal device.
Above-mentioned existing portable power source, must use extra two ends that the cable of USB plug is set during charging, once leave behind cable can't use, use inconvenient; Simultaneously, the USB plug of its cable must be complementary with the USB socket of mobile terminal device, and the different mobile terminal device for USB socket needs to be equipped with different cables, uses inconvenience, and versatility is poor.
Summary of the invention
The purpose of this utility model is to provide a kind of Portable power source that additionally uses the USB cable just can directly be charged to the mobile terminal mobile terminal device that do not need, to improve the convenience of its use.
A kind of Portable power source described in the utility model, comprise battery and the circuit board installed in power supply body, power supply body, circuit board connects USB plug by data cable, the surface of power supply body arranges the groove that matches with the USB plug shape for fixing USB plug, USB plug is inserted data cable while being fixed in groove and is drawn the bottom in groove in, and USB plug data cable when groove is extracted is pulled out with circuit board and is connected from groove.
A kind of Portable power source described in the utility model, when mobile terminal device is charged, USB plug is extracted from the groove of fixing it, draw in the data cable of bottom portion of groove and also pull out thereupon, then USB plug is inserted to the USB socket of mobile terminal device and can be charged; After having charged, USB plug is extracted from USB socket, data cable folding and unfolding again, in bottom portion of groove, is inserted USB plug to be fixed in groove.It does not need to carry in addition the USB cable in the process that mobile terminal device is charged, and can directly to mobile terminal device, be charged, very easy to use.
The accompanying drawing explanation
Fig. 1 is a kind of Portable power source schematic diagram;
Fig. 2 is a kind of Portable power source schematic diagram.
Embodiment
As Fig. 1, a kind of Portable power source, the battery 2 and the circuit board that comprise power supply body 1, the 1 interior installation of power supply body, circuit board connects USB plug 4 by data cable 3, the surface of power supply body 1 arranges the groove 5 that matches with USB plug 4 shapes for fixing USB plug 4, USB plug 4 insertions be fixed on groove 5 when interior data cable 3 draw in the bottom of groove 5.Data cable 3 is spring wire, has both saved the space of store data cable 3, facilitates again the withdrawal of data cable 3, and when USB plug 4 is extracted from groove 5, data cable 3 is pulled out with circuit board and is connected from groove 5.
Groove 5 bottoms can arrange the elasticity winder, and described data cable 3 can be wrapped on the elasticity winder.Can reclaim more easily cable by the elasticity winder.
As Fig. 2, further, circuit board is connected with the USB plug 4 of two by two single data cables 3, and the surface of power supply body 1 arranges 5, two grooves 5 of two grooves and matches with two USB plug 4 shapes respectively.Two USB plug 4 can be the USB plug of common specification, and in order to be applicable to the USB plug of i Phone specification, another is the USB plug that is applicable to Samsung mobile phone specification, thereby can meet the charging demand of most of mobile terminal device as one, and versatility is good.
Described USB plug 4 and corresponding groove 5 also can be three even more, the specification of each USB plug 4 is different, by the USB plug 4 that different size is set, further strengthens applicability and the versatility of described Portable power source.
Further, cover one deck leather layer at the back side of power supply body 1.Make the profile of Portable power source more attractive in appearance, high-grade.
Again further, the front of power supply body 1 arranges mirror surface structure.Make Portable power source attractive in appearance, the fashion that seems, can print the information such as trade mark of businessman on mirror surface structure, meet the publicity demand of businessman simultaneously.
