Specific embodiment

Below it is only the preferred embodiment of the utility model, does not therefore limit the protection scope of the utility model.

Screen display charger please refers to shown in Fig. 1-3, comprising: shell 1, display screen 2, switch key 3, USB interface 6, pin 5 and circuit board 4, display screen 2, switch key 3, USB interface 6, pin 5 be electrically connected at circuit board 4.

Shell 1 is made of plastic material, and shell 1 is assembled using left and right fastening form, and USB interface 6 is installed on shell 1 And the access port of USB interface 6 is revealed in shell 1, is inserted into and connects for USB data line.

The pin 5 is articulated in shell, can rotate around shell 1, and shell 1 is equipped with accommodating groove 10, and pin 5 exists It screws out out of accommodating groove 10 when use, screws in accommodating groove 10 when not in use, and the specific national standard of pin 5 is not particularly limited, It is modified for different national standards.

The display screen 2 is set on shell 1, for showing current charge condition.

It please refers to shown in Fig. 3-6, the circuit board 4 is equipped with MCU control module 41, AC power supplies module 42, USB output Module 43, signal detection module 44, LED display module 45 and switch module 46, AC power supplies module 42, USB output module 43, Signal detection module 44, LED display module 45 and switch module 46 are all connected to MCU control module 41.

In the setting of hardware, switch key 3 is provided on shell 1, circuit board 4 can be divided into 401 He of first circuit board Second circuit board 402,402 connection switch key 3 of second circuit board, and second circuit board 402 are connection first circuit boards 401 , fluting is offered on first circuit board 401, second circuit board 402 is inserted into first circuit board 401 and is electrically connected, and the two is stablized Connection.And shell 1 has the left shell and right shell body being combined with each other, it, should in being provided on left shell or right shell body in snap-gauge 101 Snap-gauge 101 is protruded to first circuit board 401, and offers groove body on first circuit board 401, is passed through for snap-gauge 101, is enabled circuit Plate 401 is fixed on shell.

The function of the utility model is very more, can be realized by each circuit module automatically power off, power-off restarting, charging Status display etc. illustrates further below.

The utility model is with automatic circuit break function, all electricity under socket plug-in light condition, on circuit board 4 Road modular program self-test is opened, and display screen 2, LED light are all turned at this time；It is negative when being plugged on socket by USB interface 6 After load, display screen 2 shows electric current, voltage, and rotation is shown, to show charging situation.And open: is indicated certainly when LED light is bright Dynamic circuit breaker Electricity Functional is opened, and can be switched to non-automatic power down function by switch key 3, and indicator light extinguishes at this time.From dynamic circuit breaker Fully charged under Electricity Functional, display screen 2 and LED light are all extinguished after the LED light quick flashing several seconds, close output.
