Description

With the mobile charging wiring board of USB interface
Technical field
The utility model relates to a kind of wiring board, particularly relates to a kind of mobile charging wiring board with USB interface.
Background technology
Wiring board is the necessary article of each household family, but along with the high speed development of science and technology, increasing small household appliances start to adopt USB interface, wiring board traditional at present can only provide common civil power, be not with and can supply mobile phone, MP3, the equipment charges such as MP4 power autonomous, be not with USB to connect jack, and electric power connection line and patch panel main body connect together, and non-dismountablely get off, when to the charging of mobile devices such as mobile phone, MP3, MP4, necessary external power supply transducer and data wire, when out on tours or office, carry very inconvenient.And there is no energy storage device in traditional wiring board, when have a power failure and do not have power supply unit local time, wiring board cannot work, so traditional wiring board can not meet present instructions for use.
Utility model content
The technical problems to be solved in the utility model is to power to USB interface for wiring board in prior art, the defect of electricity cannot be stored, a kind of mobile charging wiring board with USB interface is provided, also can powers to USB interface while exporting civil power, and with storing the function of electricity.
The utility model solves the technical scheme that its technical problem adopts:
The utility model provides a kind of mobile charging wiring board with USB interface, it is characterized in that, comprise patch panel main body, this patch panel main body is provided with multiple cities electric jack and at least one USB interface, this patch panel main body inside is provided with energy storage device, and the current rectifying and wave filtering circuit to be connected with this energy storage device, USB interface is connected with this current rectifying and wave filtering circuit, and this current rectifying and wave filtering circuit is also electrically connected with city by transformer.
Described patch panel main body is provided with mains switch, charge switch and discharge switch, charge switch is connected with energy storage device, and discharge switch is connected with USB interface.
This patch panel main body is also provided with electric source line interface, and the plug of wiring board is removably connected by power line and this electric source line interface.
Described patch panel main body is provided with multiple electric energy indicator light, this electric energy indicator light is connected with energy storage device.
The beneficial effect that the utility model produces is: a kind of mobile charging wiring board with USB interface of the present utility model, by civil power is changed into low voltage, and through inner current rectifying and wave filtering circuit, the function of powering to USB interface while realizing exporting civil power, wiring board is built-in energy storage device also, realizing when not connecing external power source is the independently-powered function of USB interface, simple to operate, easy to use.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail, in accompanying drawing:
Fig. 1 is the planar structure schematic diagram of the mobile charging wiring board of the utility model example belt USB interface;
Fig. 2 is the schematic block circuit diagram of the mobile charging wiring board of the utility model example belt USB interface.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, the mobile charging wiring board of the utility model band USB interface, comprise patch panel main body 2, this patch panel main body 2 is provided with multiple cities electric jack 8 and at least one USB interface 6, this patch panel main body inside is provided with energy storage device 11, and the current rectifying and wave filtering circuit 9 to be connected with this energy storage device 11, USB interface 6 is connected with this current rectifying and wave filtering circuit 9, and this current rectifying and wave filtering circuit 9 is also electrically connected with city by transformer 10.When connecting external power source, civil power input is powered for energy storage device 11 and USB interface 6 by after current rectifying and wave filtering circuit 9, and when not connecting external power source, passing through current rectifying and wave filtering circuit 9 by energy storage device 11 is that USB interface 6 is independently-powered.
In an embodiment of the present utility model, patch panel main body 2 being provided with mains switch 3, charge switch 4 and discharge switch 5, when connecting external power source, turning on the power switch 3, city's electric jack 8 and USB interface 6 just can start power supply; Open charge switch 4, civil power input, just by the adjustment by transformer 10 and current rectifying and wave filtering circuit 9, is charged to energy storage device 11; When not connecting external power source, open discharge switch 5, the electricity in energy storage device 11 just by by after the adjustment of current rectifying and wave filtering circuit 9, is exported by USB interface 6.
Patch panel main body 2 and plug 1 connection are provided with an electric source line interface 12, plug 1 is removably connected by power line and this electric source line interface 12, thus realize plug 1 and can be separated with patch panel main body 2 at any time, such patch panel main body 2 just independently can use as a portable power source, powers to USB interface 6.
Patch panel main body 2 is also provided with multiple electric energy indicator light 7, for showing charged state and the information about power of energy storage device 11, when connecting external power source and charging to energy storage device 11, many brighten by electric energy indicator light 7, when whole electric energy indicator lights 7 all brightens, represent that the electricity of energy storage device 11 is full of; When not connecting external power source, open discharge switch 5, electric energy indicator light 7 by according to the quantity lighted to represent the dump energy in energy storage device 11.
Patch panel main body 2 inside is provided with transformer 10, this transformer is arranged between civil power input and current rectifying and wave filtering circuit 9, civil power input first will pass through transformer 10 step-down, utilize electromagnetic induction principle, convert civil power to lower voltage, at this moment voltage is mixed and disorderly, must again through rectifier circuit rectifies, general employing full bridge rectifier, convert alternating current to direct current, but voltage is still unstable, if directly connect power consumption equipment, the fluctuation of voltage can damage power consumption equipment, at this moment a L-C filter circuit will be added, pass through inductance, the effect of electric capacity, reduce the fluctuation of voltage, make voltage stabilization a less scope.
In sum, the utility model is by changing into low voltage by civil power, and through inner current rectifying and wave filtering circuit, the function of powering to USB interface while realizing exporting civil power, wiring board is built-in energy storage device also, realizing when not connecing external power source is the independently-powered function of USB interface, simple to operate, easy to use.
Should be understood that, for those of ordinary skills, can be improved according to the above description or convert, and all these improve and convert the protection range that all should belong to the utility model claims.
