Plug 13 has multiple pins, and one end of the pin is fixedly connected on shell 14, and with the charging in shell 14
Protection portion is connected, in embodiment, and pin is two.
As shown in figure 1, USB connecting lines 20 are connected by USB interface with housing 10；USB connecting lines 20 include：USB plug
21st, data wire 22, charging plug for mobile phone 23.
USB plug 21 and charging plug for mobile phone 23 are separately positioned on the two ends of data wire 22.
Touch control unit is arranged on charging plug for mobile phone 23, in embodiment, and touch control unit is to be arranged on charging plug for mobile phone
On button 3.
Charge protection portion, is arranged in housing 10, and USB connecting lines 20 are connected by usb 11；Charge protection portion includes
Charging circuit, charging control unit, relay and built-in power.
Charging circuit connects civil power by relay, and charging control unit includes control circuit and is arranged in control circuit
Control unit, sensing element, control unit is connected with touch control unit, sensing element and relay respectively, for receiving simultaneously
Handle after the data from sensing element, obtain the control signal of control relay working condition.Sensing element is voltage sensor
Device or current sensor.In embodiment, sensing element is current sensor, and built-in power is control centered on battery, control unit
Coremaking piece.
Fig. 3 is charger control principle schematic diagram in embodiments of the invention.
Control circuit as shown in Figure 3, including power supply VCC, resistance R2, button 3, center control chip 5, diode D1,
Light emitting diode D2, resistance R1, electric capacity C1, triode Q1, relay RL1, central die input port 1 (P1.0), central die
Delivery outlet 2 (P2.0), central die input port 4 (P1.7), AD sampling modules 6, current sensor 7.
Button 3 is arranged on charging plug for mobile phone 23, and when user inserts USB connecting lines 20 to mobile phone, meeting nature is pinned
The button 3, sends the signal switched on power, and concrete principle is as follows：
Button 3 in control circuit is pressed, then the light emitting diode D2 in main current paths, and main circuit is bright.
Control the center control chip in circuit to detect the curtage of circuit, hand is not connected with when detecting charger
Machine, then main circuit is breaking, and the light emitting diode D2 in main circuit goes out.
As shown in figure 3, when button 3 is pressed, low level input center control chip input port 1, now, center control core
Piece delivery outlet exports high level, main current paths.Due to path, triode Q1 reaches full turn-on condition so as to saturation conduction, three
During pole pipe Q1 saturation conductions, left end control circuit pathways, electric capacity C1 is started to charge up, and relay RL1 obtains electric, in relay RL1
Portion's normally opened contact closure, the right main current paths, light emitting diode D2 is bright.
When the current sensor 7 in control circuit detects electric current, and corresponding current value is gathered by AD sampling modules 6,
When center control chip input port 4 receives sampled value, center control chip 5 is by the standard value of sampled value and charger normal work
After comparing, if both differences are larger, that is, detect charger and be not connected with mobile phone, now, the delivery outlet 2 of center control chip 5, output
Low level, main circuit can be regarded as in off state.Although breaking, electric capacity C1 discharges, of short duration maintenance triode Q1 and relay
Device RL1 is powered, until electric capacity C1 discharge offs, and triode Q1 becomes cut-off state, left side control circuit dead electricity, relay RL1
Dead electricity, so the right main circuit disconnects, main circuit open circuit, light emitting diode D2 goes out.(electric capacity C1 and diode D1 here is played
Protective effect, diode current flow when triode Q1 is changed into cut-off from conducting of sustained diode 1, by relay coil
Induced electromotive force is limited to a PN junction step-down so that triode Uce=VCC, avoids the induced electromotive force and power supply electricity of coil
Laminated adds damage triode.)
In addition, the circuit also includes battery one small, (volume very little, charge capacity requires also very low, is only used as instantaneously connecing
Circuit passband produces a pulse signal just), dispose battery (smaller chargeable) to allow for mobile phone in charger here complete
Do not have the extremity of electricity entirely and must not be not provided with.Originally it is intended to the dump energy in mobile phone to send charging signals, drives
What dynamic civil power was connected with charging circuit.
Mobile phone socket end set button (custom when being charged the phone according to people, this position be bound to by
Pressing).User can naturally touch button when charging, and this is to transmit a signal to center control chip, charging
Circuit is electrically connected with city.When user pulls up mobile phone, the data measured can be transmitted to center control core by voltage or current sensor
Piece, center control chip judges that meeting control relay is electrically disconnected with city by charging circuit not after charged state.
The effect of embodiment and effect
The energy-saving safety charger for mobile phone that the present embodiment is provided can realize charging circuit automatically when user stops charging
With the disconnection of civil power, realize fully powered-off；And be again electrically connected charging circuit with city in charging next time, realize charging
Function.
