A kind of compact power
Technical field
The utility model relates to a kind of power supply, especially a kind of compact power.
Background technology
At present, because people use to such an extent that portable digital equipment kind is more and more, for example MP3, MP4 and mobile phone etc., this kind equipment all is equipped with a charger, but works as people outdoor, in the time of can't using socket, then can't use this type of charger to carry out the charging of above-mentioned digital equipment, and because the function of above-mentioned digital equipment is more and more, and screen is also more and more meticulousr, the increasing problem of power consumption has appearred also thereupon.
In order to solve outdoor charging problem, so occurred a kind of compact power on the market, this type of compact power generally comprises a shell, portion is provided with a rechargeable battery in the enclosure, shell is provided with and is used for to the AC plug of this rechargeable battery charging and the power line that is used to connect the equipment of being recharged, give after this compact power charging, this compact power can the linking number decoding apparatus and logarithmic code equipment charge, thereby the situation of having avoided digital equipment can't use in outdoor outage.But the power line of existing portable charger generally all is scattered in outside the compact power, more mixed and disorderly when depositing, perhaps charger housing and power line are separable structure, can separately deposit, but this kind situation easily cause losing of power line and can't use.
Summary of the invention
The purpose of this utility model provides a kind of power line and carries compact power convenient and that can not lose.
To achieve these goals, the utility model adopts following technical scheme:
It comprises upper casing and lower casing, described upper casing and lower casing are formed an accommodation space, are provided with pcb board and rechargeable battery in the described accommodation space, and described pcb board connects a power line, its improvement is: the junction of described upper casing and lower casing is provided with a winding slot, and described power line is around in this winding slot.
Preferably, described loam cake or under cover and be provided with male lid, place the joint of power line in the described male lid.
Preferably, described rechargeable battery connection one AC that can directly charge directly fills plug.
Preferably, described AC plug is a Collapsible structure, loam cake or cover down to be provided with and stir the flexible shifting block of AC plug.
Owing to adopted said structure, compact power described in the utility model can be around in power line in the winding slot obsolete the time, thereby avoided power line mixed and disorderly be scattered in the compact power outside, and because on connection of an end of power line and the pcb board, so both guaranteed the convenience that carries, and made power line can not lose again.
Description of drawings
Fig. 1 is the design of part schematic diagram of the utility model embodiment;
Fig. 2 is the combining structure schematic diagram of the utility model embodiment.
The utility model purpose, function and advantage will be in conjunction with the embodiments, are described further with reference to accompanying drawing.
Embodiment
As shown in Figures 1 and 2, embodiment of the present utility model comprises upper casing 1 and lower casing 2, described upper casing 1 and lower casing 2 are formed an accommodation space, be provided with pcb board 4 plates and rechargeable battery 5 in the described accommodation space, described pcb board 4 connects a power line 41, the junction of described upper casing 1 and lower casing 2 is provided with a winding slot 6, and described power line 41 is around in this winding slot 6.
Because an end of power line need be provided with a structure that is connected with digital equipment, this structure is greater than the diameter of power line, can't wind as in the winding slot 6, in order further to realize high portability, described loam cake 1 of present embodiment or lower cover 2 are provided with male lid 7, place the joint of power line 41 in the described male lid 7.
Existing compact power is general or connecting computer by the usb data line charges, or charges by connecting a power source special, the modest charger that needs to connect computer or USB straight cutting AC, and the latter needs power source special, and is all inconvenient.So present embodiment also comprises an AC and directly fills plug 3, this AC is directly filled plug 3 insertion sockets can charge to rechargeable battery.
Because when AC plug 3 often is exposed to housing exterior, when carrying, may scratch the screen of digital equipment, portable in order further to strengthen, the described AC plug 3 of present embodiment is a Collapsible structure, and loam cake 1 or lower cover 2 are provided with stirs the shifting block 31 that AC plug 3 stretches.When not using, can stir shifting block 31 the AC plug is withdrawn into enclosure interior.
The above only is a preferred embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to be done; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
