The present invention generally relates to a power device and, in particular to a smart power device.
An electric appliance is usually in standby mode without powering off automatically when not in use. However, electrical appliances will still cause power loss even if they are not running; thus, it does not satisfy the environmental protection requirements of energy conservation and carbon reduction.
Moreover, with the popularity of cloud computing platforms, power management and power control also keep up with the times. Therefore, power products need to be adjusted internally in response to system instructions, such as shutdown, startup, or status reporting, etc. to meet requirements of the cloud computing. In addition, the appearance of today's products requires miniaturization. In this regard, how to provide a miniature smart power device is the research motivation of the inventor.

The communication circuit is capable of receiving a wireless signal for generating a command signal. The control circuit generates a control signal according to the command signal. The switching circuit has a first cable and a second cable and is capable of conducting or interrupting the first cable and the second cable according to the control signal. The power transfer unit is electrically connected with the switching circuit for receiving an AC input voltage and will supply an output voltage according to the control signal. The power transfer unit comprises a main shell seat, a first conductive sheet, a second conductive sheet, a separation shell seat and a separation conductive sheet.

In an embodiment of the present invention, the first conductive sheet 22, the second conductive sheet 23, the separation conductive sheet 25 and the grounding conductive sheet 26 are U-shaped conductive sheets separately. Moreover, the first receiving slot 211, the second receiving slot 212, the separation shell seat 24 and the grounding slot 214 are open slots separately for increasing creepage distances by recessed structures. Therefore, the safety of the invention will be enhanced while using.
Specifically, the insertion portion 213 is located at a side of the second receiving slot 212. The main shell seat 21 has formed with a positioning block 2121 at the second receiving slot 212.
