Description is being not limited to scope of the present application for the purpose of the rule for illustrating the application.The protection domain of the application
When subject to appended claims institute defender.
Fig. 1 is please referred to, external controlled with quick charge of the mobile device of the utility model switchs, including：Switch control mould
Block, the switch control module connect power switch, and the power switch is connected across on positive pole as defined in usb protocol, fills
Between electric appliance and mobile device.
Preferably, the mobile device be can only mobile phone, between mobile phone and charger be inserted into a controlled mechanical electric
Source switch, electronic switch, the position of the switch are to be connected across on positive pole as defined in usb protocol, charger and mobile phone it
Between, control terminal is labeled as K1（Similarly hereinafter）.The function of K1 is to control the opening and closing that switch is concatenated on power cord as defined in usb protocol.
Preferably, two controlled line switch signals are inserted between mobile phone and charger, mechanical switch, electronic switch are equal
Can, the position of the switch is to be connected across respectively on two signal wires as defined in usb protocol, between charger and mobile phone, control terminal point
Biao Ji not be, K3（Similarly hereinafter）.Since the control logic of K2 and K3 is identical, the same time control of the same control signal may be used
K2 and K3 processed are labeled as K23（Similarly hereinafter）.K23（K2 and K3）Function be control usb protocol as defined in two signal wires connection
And disconnection.
As shown in Fig. 2, the switch control module of this specific embodiment includes：Triode Q1, emitter connect R1 and R3,
The base stage of R3 connecting triodes Q2, there is over-current and -load short-circuit protection function.When load overload or short circuit, the current collection of Q1
Electrode current increases, and the emitter resistance R1 of Q1 will produce higher pressure drop, the high voltage meeting of this overload or short circuit generation
Q2 saturation conductions are allowed by R3, prevent overload from damaging to allow Q1 cut-offs to stop output.As shown, T1 transformers are inductance members
Part, Q1 are operated on off state, when Q1 ends, very high voltage can be induced in collector, this voltage may be up to
1000 volts or more, this can make Q1 punch through damage, and now with high speed switch tube D5, this voltage can charge to C4, absorb this
A high pressure can be discharged by R5 immediately after C4 chargings, and such Q1 will not have been damaged because of the high electrical breakdown of collector with 1 Europe
Resistance F1 plays the role of fuse, and rectified action is completed with a diode D1.After powering on, C1 has 300V's or so
DC voltage provides electric current by R2 to the base stage of Q1, the emitter of Q1 have R1 current sense resistors R1, Q1 base stage obtain it is electric after,
T1 can be passed through（3、4）Collector current is generated, and simultaneously T1's（5、6）（1、2）Upper generation induced voltage, the two are secondary
The identical coil of the number of turns of insulation, wherein T1（1、2）Output after D7 rectifications, C5 filtering by passing through USB powering loads；Wherein
T1（5、6）Pass through IC1 after D6 rectifications, C2 filtering（Actually 4.3V voltage-stabiliser tubes）, Q2 composition sampling comparison circuit, detection output electricity
Pressure height；Wherein T1（5、6）, C3, R4 also form the positive-feedback circuits of Q1 triodes, allow Q1 to be operated in the higher-order of oscillation, ceaselessly
To T1（3、4）Switch power supply.When load lightens or output voltage is caused to increase for the high any reason of supply voltage change, T1
（5、6）, IC1 samplings compare Q2 caused to be connected, Q1 base currents reduce, and collector current reduces, and load capacity becomes smaller, to lead
Output voltage is caused to reduce；After output voltage reduces, it can end again after Q2 samplings, the load capacity of Q1 becomes strong, and output voltage is again
It can increase；Play the role of automatic voltage regulation in this way.
