The utility model content
Carry inconvenience, preserve the low problem of loaded down with trivial details and traditional wiring board utilance for solving the USB power supply, the purpose of this utility model is to provide a kind of USB power supply wiring board.
For achieving the above object, the utility model is mainly by the following technical solutions:
A kind of USB power supply wiring board, comprise wiring board, described wiring board is provided with a plurality of USB socket parallel with one another, and this USB socket is made of USB output interface and power supply changeover device, the output of described power supply changeover device is connected with the USB output interface, and input is connected with the civil power input power cord.
Wherein said power supply changeover device includes transformer, rectification filtering module and voltage stabilizing circuit, and input voltage carries out rectifying and wave-filtering by rectification filtering module after the transformer step-down, and by outputing to the USB output interface after the voltage stabilizing circuit voltage stabilizing.
Wherein also include a plug, this plug is connected with wiring board by power line.
Compared with prior art, the utlity model has following beneficial effect:
1, the user only need carry the USB connecting line and can realize multiple digital electronic goods are charged or power, and has avoided carrying too much USB power supply changeover device joint, has alleviated user's burden.
2, the USB socket output voltage on the wiring board in the utility model only between 0～20V, is lower than the human safety voltage, has higher fail safe.
3, the USB socket quantity that can hold on the wiring board of identical size wants many more than the quantity of conventional power source wiring board institute attachment plug, has improved the utilance of wiring board greatly.

Identifier declaration among the figure: wiring board 101, USB socket 102, power line 103, plug 104, shell 201, USB socket 202, USB connecting line 203, body of wall 204, mains switch 205.
Embodiment
Core concept of the present utility model is: the utility model power supply wiring board is provided with a plurality of USB socket, USB power supply changeover device in these USB socket is connected in parallel each other, electric main is input to the direct current that is converted into 0～20V behind the USB power supply changeover device, and export by the output interface in the USB socket, the USB connecting line then can directly be connected with this output interface, thereby is embodied as power supply of external electrical product or charging.The utility model has carried out conventional power source wiring board and USB power supply to combine effectively, has improved the utilance of power supply wiring board, and is convenient for users to use.
For setting forth thought of the present utility model and purpose, the utility model is described further below in conjunction with the drawings and specific embodiments.
See also shown in Figure 3ly, Fig. 3 is the structural representation of the utility model first preferred embodiment.Wherein the wiring board shown in the figure is socket, mainly include plug 104, power line 103 and wiring board 101, described plug 104 is connected with wiring board 101 by power line 103, described wiring board 101 is provided with a plurality of USB socket parallel with one another 102, these USB socket 102 all are to be made of USB output interface and power supply changeover device, and described power supply changeover device is connected with said power 103.
Because the shared space of USB socket 102 is much smaller than the conventional socket jack, therefore the quantity of the USB socket 102 that is distributed on the wiring board 101 will be far more than the conventional socket jack, the wiring board of identical like this size the external electrical product that can connect simultaneously, the utility model is more than traditional wiring board.
As shown in Figure 4, Fig. 4 is the structural representation of the utility model second preferred embodiment.Wherein the wiring board among the figure is the plate that is installed in the body of wall 204, and it mainly includes shell 201, USB socket 202, USB connecting line 203 and is arranged on mains switch 205 on the shell 201.USB socket 202 has a plurality of, be installed in the shell 201, and the output port on the USB socket 202 is evenly distributed on the shell 201, and 203 of USB connecting lines are connected with above-mentioned output port, and the on off operating mode of above-mentioned USB socket 202 out-put supplies then is to control by mains switch 205.
