Abstract
The utility model relates to the field of electrical engineering, in particular to a power supply switcher of a router. The power supply switcher comprises a control circuit board and a power adapter, and is characterized in that a self-switching module, a boosting module and an overcurrent protection module are arranged on the control circuit board which is provided with two USB interfaces and a router connecting line port, the self-switching module is connected with the power adapter, the two USB interfaces are used for supplying power to the router via laptop power, and the self-switching module can be connected via two Schottky diodes with low voltage-drop. When in power supply, the USB interfaces are clamped via a power source of the adapter and can be supplied with power automatically after power off. In addition, the power supply switcher has the advantages of reasonable structure, simple operation, convenient use and the like.
Description
Technical field
The utility model relates to the electrical engineering field, is a kind of power supply switch of router specifically.
Background technology
As everyone knows; current router, switch, adsl router on the market adopts 220V to exchange usually changes direct current supply; wherein common direct voltage has 5v, a 9v; 12v; for conventional router; in some place of rationing the power supply, and burst has a power failure, when cutting off the power supply, will cause and can't surf the Net in school or life office occasion.
Summary of the invention
The utility model is at the deficiency that prior art exists, and proposes a kind of power supply switch of router of surfing the Net can realize cutting off the power supply the time.
A kind of power supply switch of router; comprise control circuit board, power supply adaptor; it is characterized in that control circuit board is provided with adaptive switched module, boost module, overcurrent protection module; adaptive switched module is connected with current adapter, and control circuit board is provided with USB interface and router connecting line mouth.
The utility model control circuit board is provided with two USB interface, is used to realize that laptop powers to router.
The utility model in use; with modal router supply power voltage 9V power supply on the market is representative; by the USB interface on the control circuit board is connected with notebook computer; router connecting line mouth on the control circuit board is connected with router; thereby the power supply in the use notebook computer is powered to router; wherein the power supply parameter of USB interface is 5.0v/500ma; because the USB supply current of general notebook is all greater than this value; therefore use the driving router that two USB interface can be successful; the processing of notebook voltage that USB interface provides boost module on control circuit board obtains the voltage a little less than 9V; overcurrent protection module on the control circuit board is used for USB interface is carried out overcurrent protection simultaneously; adaptive switched module in the utility model; can adopt the Schottky diode of two low pressure drops to connect; adaptor power supplies is clamped to the USB mouth during power supply; automatically transfer the USB power supply after the outage to, the utlity model has rational in infrastructure; simple to operate; the significant advantage of grade easy to use.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is further described.
Accompanying drawing is a structural representation of the present utility model.
Reference numeral: control circuit board 1, power supply adaptor 2, adaptive switched module 3, boost module 4, overcurrent protection module 5, USB interface 6, router connecting line mouth 7
