Description

The power supply of safety keyboard
Technical field
The utility model relates to the power supply of safety keyboard.
Background technology
The DC power supply of the upper use of circuit board mostly is 5V at present, 12V's and so on, the power supply that a lot of people adopt test chamber to provide, or special-purpose stabilized voltage power supply.Because test chamber, stabilized voltage power supply are larger, and be very inconvenient when debugging circuit board, also is not easy to carry.
The utility model content
The purpose of this utility model provides a kind of power supply of safety keyboard, and power supply brings when reducing debug circuit trouble and inconvenience utilize the USB line of charger for mobile phone to transform the device of 5V DC power supply as.
The utility model is achieved through the following technical solutions: the power supply of this safety keyboard comprises mobile electronic equipment charger, the USB interface that is connected with this mobile electronic equipment charger, the data wire of connection USB interface and safety keyboard circuit board.
Power line in the data wire and ground wire access security keyboard pcb.
Beneficial effect: the utility model is simple in structure, be easy to carry, and the charger that can take full advantage of the electronics mobile device is transformed, and has satisfied the user demand of actual safety keyboard, has improved economic benefit.
Description of drawings
In order to be easy to explanation, the utility model is done to describe in detail by following specific embodiment and accompanying drawing.
Fig. 1 is the utility model structural representation.
Embodiment
As shown in Figure 1, the power supply of this safety keyboard comprises mobile electronic equipment charger 1, the USB interface 2 that is connected with this mobile electronic equipment charger 1, the data wire 4 of connection USB interface 2 and safety keyboard circuit board 3.Power line in the data wire 4 and ground wire access security keyboard pcb 3.
Take waste and old charger for mobile phone as example, waste and old charger for mobile phone is got involved the 220V alternating current in the present embodiment, after USB interface 2 conversions, form the direct current of 5V between blue white two colo(u)r streaks in the data wire 4, access security keyboard pcb 3 is for it.The USB interface that has is 5 lines, behind the alternating current of charger for mobile phone access 220V, carefully detects in twos with universal instrument, can obtain the DC power supply of 5V.
The utility model is simple in structure, be easy to carry, and the charger that can take full advantage of the electronics mobile device is transformed, and has satisfied the user demand of actual safety keyboard, has improved economic benefit.
The above only be embodiment of the present utility model, but protection range of the present utility model is not limited to this, and any variation or replacement of expecting without creative work all should be encompassed within the protection range of the present utility model.Therefore, protection range of the present utility model should be as the criterion with the protection range that claims were limited.
