Collecting work, if test point is selected in one end that the output end of charger for mobile phone is namely connected with mobile phone, output end
Wherein single line will pass through Hall sensor, so this with line just into private cable, use is extremely inconvenient, such as clicks test
If one end that the input i.e. charger of charger for mobile phone are connected with power supply, external charger and cable do not have and changed
Dynamic, any one charger for mobile phone can be used directly.Therefore, test point is selected in the input of charger for mobile phone.Data are adopted
Collection work seeks to determine the size of current of several states of mobile phone charging.After power outlet single line one ammeter of series connection
Tested, it was therefore concluded that：1st, alternating current 220V end electric current is 1.2mA during charger zero load.2nd, DC5V 500mA charging is exported
Alternating current 220V end electric current is 5mA when device charges, and alternating current 220V end electric current is 2mA when fully charged rear charger charges.3rd, export
Alternating current 220V end electric current is 7mA during DC5V 1A charger charging, and alternating current 220V end electric current is when fully charged rear charger charges
2mA, in view of mobile phone is full of per se with charge protector is automatically stopped charging, and newly battery suggestion was full of 8 hours, therefore,
1mA is arranged to by protective current is offline, due to the 1mA threshold values drawn based on science detection so that the present apparatus has practicality.
3rd, this patent also includes latching circuit using the safe socket for recharging, and the latching circuit includes master switch
SBon, the master switch SBon one end are connected to charging inlet wire one end, and the master switch SBon other ends are connected to relay
Ks contact one end, one end of another contact of master switch SBon one end connection relay K1, the relay K1's
The other end of another contact is connected to the master switch SBon other ends, because the present apparatus is by meter housing, switch, supply hub, electricity
The composition such as detection module, relay is flowed, self-locking (providing power supply for module) is built using relay and interlock circuit (breaks power supply
Connection) coordinate with current detection module and realize current detecting and act control point progresss is corresponding, due to latching circuit and mutual
The cooperation of lock circuit, improve the stability of charging circuit power supply.
4th, this patent also includes emergency cut-off circuit using the safe socket for recharging, and the emergency cut-off circuit includes tight
Anxious button SBoff, described danger button SBoff one end are connected to charging inlet wire one end, and its other end is connected to relay K2's
Coil one end, the coil other end of the relay K2 are connected to the charging inlet wire other end, contact one end of the relay K2
The other end that normally-closed contact one end is connected to relay K1 another contact is connected to, its other end is connected to master switch SBon

In wire through overcurrent in normal range (NR), relay K does not work in module, and cell phone intelligent charging socket normally charges for mobile phone
Device provides alternating current 220V voltage.Detected when charger for mobile phone disconnects the Hall sensor on current detection module with mobile phone
Changed through its wire magnetic flux, and be converted into electric signal, analyzed in this wire and pass through through current detection module
Electric current be less than setting electric current lower limit, relay K adhesives in module, time relay KS is powered when reaching the delay of setting
Between adhesive, time relay KS normally-closed contact disconnects, and relay K1 powers off its normally opened contact K1 disconnections, alternating current 220V output end
Power-off.Because AC/DC power transfer modules are in parallel with relay K1, now power transfer module power-off is not examined for electric current
Survey module and dc source is provided, current detection module is stopped, so as to ensure that whole equipment is in fully powered-off state.When
During charger for mobile phone short circuit occurred inside failure, the Hall sensor on current detection module detects the wire magnetic flux through it
Amount is changed, and is converted into electric signal, and the electric current passed through in this wire is analyzed through current detection module higher than setting electricity
Stream higher limit cell phone intelligent charger can make above-mentioned action, disconnect alternating current 220V out-put supply.For a mobile phone it is fully charged
As long as want to continue as connecting mobile phone during another mobile phone charging in the delay time of setting afterwards, the Hall on current detection module
Sensor detects to change through its wire magnetic flux, and is converted into electric signal, is analyzed through current detection module
The electric current passed through in this wire recovers normal, and relay K disconnects in module, and time relay KS power-off, its normally-closed contact KS is not
It can disconnect, alternating current 220V output end is by continued power.There is any time of voltage output by close key in alternating current 220V output end
Electrical equipment K2 adhesives, the normally-closed contact K2 that relay K2 cut-in relay K1 feeder ears form interlocking disconnect, whole down circuitry, risen
To the effect that can close power supply at any time, the utility model solves prior art and prior art be present in the presence of because people ignore
