Utility model content
The purpose of this utility model is to provide a kind of USB deconcentrator control board, to improve the problem that the multiple USB interface of common USB deconcentrator control board can not independently control.
The USB deconcentrator control board that the utility model provides comprises circuit board, multiple USB output interface, the multiple switch controlling described USB output interface power supply and USB power source input interface, described USB output interface, described switch and described USB power source input interface are fixed on described circuit board, described USB output interface is connected by described circuit board with described USB power source input interface, the quantity of described switch is identical with the quantity of described USB output interface, and a described Switch Controller should control the power supply of a described USB output interface.
Further, described USB deconcentrator control board also comprises second source input interface, described second source input interface is 12V power input interface, and described second source input interface is fixed on described circuit board, and described second source input interface is connected with described USB output interface; Further, described USB deconcentrator control board also comprises multiple indicator light being used to indicate described switch corresponding to described USB output interface and whether opening, and described indicator light quantity is identical with the quantity of described USB output interface; Further, a described USB output interface, a described switch and a described indicator light form a control unit, between multiple described control unit mutually and connect; Further, multiple described control unit is equidistantly fixed on described circuit board.
The USB deconcentrator control board that the utility model provides, comprise multiple USB interface, by the control of switch, can arbitrarily cut off the power supply be connected with USB interface, power supply input and output are all fixed on circuit boards, and circuit board component and USB interface are if any damage, be convenient for changing, add a power input interface simultaneously, avoid the situation occurring that electricity is under-supply, and user can select suitable power input interface according to service condition.
For making above-mentioned purpose of the present utility model, feature and advantage become apparent, preferred embodiment cited below particularly, and coordinate appended accompanying drawing, be described in detail below.
Accompanying drawing explanation
The structural representation of the USB deconcentrator control board that Fig. 1 provides for the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
As shown in Figure 1, a kind of USB deconcentrator control board that the utility model embodiment provides, comprise circuit board 101, multiple USB output interface 102, control multiple switches 103 and the USB power source input interface 104 of described USB output interface 102 power supply, described USB output interface 102, described switch 103 and described USB power source input interface 104 are fixed on described circuit board 101, described USB output interface 102 is connected by described circuit board 101 with described USB power source input interface 104, the quantity of described switch 103 is identical with the quantity of described USB output interface 102, described switch 103 correspondence controls the power supply of a described USB output interface 102.
As the optimal way of the present embodiment, described USB deconcentrator control board also comprises second source input interface 105, described second source input interface 105 is 12V power input interface, described second source input interface 105 is fixed on described circuit board 101, and described second source input interface 105 is connected with described USB output interface 102.
Add a power input interface, avoid the situation occurring that electricity is under-supply, and user can select suitable power input interface according to service condition.
As the optimal way of the present embodiment, described USB deconcentrator control board also comprises the indicator light 106 whether multiple described switch 103 being used to indicate described USB output interface 102 correspondence is opened, and described indicator light 106 quantity is identical with the quantity of described USB output interface 102.
The power supply supply which USB output interface 102 user just more intuitively can arrive by indicator light 106 is opened, very convenient.
