Description
Technical field
The utility model relates to a kind of USB charging combination insert row.
Background technology
At present, charger for mobile phone generally all comprises for the interface that inserts mobile phone, USB connector, charging module, is used for inserting the plug of socket.The volume ratio of general charger for mobile phone is bigger, carries very inconvenient.Thereby much people usually only carry charging wire, have at desktop computer, notebook computer etc. on the electronic equipment of USB interface, are cell-phone charging.But, open electronic equipment if aim at cell-phone charging, can waste electric power.And generally all do not have the USB charging inlet on the socket, and have only the civil power interface, need the adapted charger for mobile phone to charge, thereby make cell-phone charging that inconvenience quite be arranged.
The utility model content
The utility model is the weak point that exists in the above-mentioned prior art for avoiding, and a kind of USB charging combination insert row is provided, and can not be problems such as cell-phone charging by USB interface to solve existing socket.
The utility model be the technical solution problem by the following technical solutions.
USB charging combination insert row, its design feature be, comprises circuit board, is connected with on the circuit board for the city's plug that connects outside mains power socket; Described circuit board includes a plurality of sockets, indicator light, push switch, charging module and a plurality of USB interface; Described push switch comprises for the push switch S1 of the switch of control city plug and is used for controlling the push switch S2 of the switch of charging module and USB interface.
The design feature of USB charging combination insert row of the present utility model also is:
Described indicator light comprises a plurality of LED, is serially connected with a resistance on each LED.
Described a plurality of LED comprises whether be used to indicate city's plug connects the indicator light LED0 of mains supply, is used to indicate socket and whether connects the indicator light LED1 of power supply and be used to indicate the LED2 whether USB interface connects power supply; Be connected in parallel respectively on described indicator light LED0, the LED1 and be useful on diode D0, the D1 that prevents inverse overvoltage.
Compared with the prior art, the utility model beneficial effect is embodied in:
USB charging combination insert row of the present utility model, the USB interface that charging module is set on the basis of conventional socket and is used for charging has the USB charging wire namely to can be electronic equipment chargings such as mobile phone as long as need not charger.
Insert row is made up in USB charging of the present utility model, has had the function of commercial power socket and USB charging inlet concurrently, has made things convenient for the charging of electronic equipments such as mobile phone, has made things convenient for people's work and life.
Description of drawings
Fig. 1 is the circuit structure diagram of USB charging combination insert row of the present utility model.
Below pass through embodiment, and the utility model is described in further detail by reference to the accompanying drawings.
Embodiment
As shown in Figure 1, USB charging combination insert row comprises circuit board, is connected with on the circuit board for the city's plug that connects outside mains power socket; Described circuit board includes a plurality of sockets, indicator light, push switch, charging module and a plurality of USB interface; Described push switch comprises for the push switch S1 of the switch of control city plug and is used for controlling the push switch S2 of the switch of charging module and USB interface.
Described indicator light comprises a plurality of LED, is serially connected with a resistance on each LED.
Described a plurality of LED comprises whether be used to indicate city's plug connects the indicator light LED0 of mains supply, is used to indicate socket and whether connects the indicator light LED1 of power supply and be used to indicate the LED2 whether USB interface connects power supply; Be connected in parallel respectively on described indicator light LED0, the LED1 and be useful on diode D0, the D1 that prevents inverse overvoltage.
USB charging combination insert row of the present utility model, the USB interface that charging module is set on the basis of conventional socket and is used for charging.By the USB charging inlet, can use the USB connecting line to be the charging of electronic equipments such as mobile phone easily, increased the function of socket.A plurality of indication LED are set on the socket, can show the electriferous state of socket easily.By a plurality of push switches, control the on/off of socket and charging USB mouth respectively, the convenient use.Be serially connected with resistance R on the LED, can be the LED dividing potential drop, LED is not burnt with protection.In addition, because LED0 and LED1 directly connect mains supply, be connected in parallel to the diode that prevents inverse overvoltage at LED0, LED1, avoid LED to be reversed puncture and burn out.
As shown in Figure 1, LED 0 is used to indicate city's plug and whether connects mains supply, and LED0 is connected in series with resistance R 0, and LED0 and diode D0 are connected in parallel.LED 1 is used to indicate socket and whether has connected power supply, and LED1 is luminous when city's plug is connected mains supply and switch S 1 and pressed, and LED1 is connected in series with resistance R 1, and LED1 and diode D1 are connected in parallel.LED 2 is used to indicate charging module and whether USB interface has connected power supply, and LED2 is luminous when city's plug is connected mains supply and switch S 2 and pressed, and LED2 is connected in series with resistance R 2.Charging module is used for and will offers USB interface after the line voltage step-down current limliting, and the input voltage of charging module is the 100V-240V alternating voltage, is output as the direct voltage of 5V, 2A.A plurality of sockets are used for connecting the plug of power consumption equipment.
Insert row is made up in USB charging of the present utility model, has had the function of commercial power socket and USB charging inlet concurrently, has made things convenient for the charging of electronic equipments such as mobile phone, has made things convenient for people's work and life.
