摘　　要：介绍了一种无接触供电的无线鼠标设计电路,无接触电能发射装置采用USB供电,通过自激振荡电路产生了138 kHz的高频振荡电压;无接触电能接收装置采用感应耦合方式获取电能。无线鼠标用无线模块nRF24E1构成信号发射和接收电路,该电路除具备有线鼠标全部功能外,还可以离开电脑远距离灵活操纵鼠标。A kind of contactless power supply wireless mouse design electric circuit is introduced in this paper. The contacfless electrical energy launching device uses the USB power supply, produces about the 138 kHz higher mode of oscillation voltage through the autodyne, the contactless electrical energy receiving device uses the induction coupling way gain electrical energy. The wireless mouse with the wireless module nRF24EI constitution signal launch and the accepting circuit, this electric circuit besides has the wired mouse complete function, but also may leave the computer long-distance range to operate the mouse nimbly.
