After fastening, alternating current reaches the first coil 1122 through first connecting portion 114, first circuit board 113, in exchange electro ultrafiltration
Under, the first coil 1122 generates changing magnetic field, while the first magnetic part 1123 generates alternating flux；The alternating flux
Across second magnetic part 1223, and then second coil 1222 is made to generate induced current, the induced current is through second
Circuit board 123, second connecting portion 124 are sent to electronic equipment.
Specifically, please refer to 11A, Figure 11 B, Figure 12 A and Figure 12 B, when first connector 11 connects alternating current
Afterwards, the safe standby state in zero loss, under such state.After second connector 12 is contacted with the first connector 11, it is set to
The first induction module 1161 on first connector 11 senses that the second connector 12 is close, and control inductive switch 1154 is closed,
Alternating current is converted to direct current through the first rectification module 1151, while first control module 1155 receives DC signal,
It controls the first switch 1156 to close for the first time, realizes that 11 circuit of the first connector is instantaneously connected to；Direct current is through the first filtering
It is again converted to alternating current after module 1152 and the first conversion module 1153 and reaches first coil 1122, the first coil 1122
Changing magnetic field is generated, while the first magnetic part 1123 generates alternating flux；The alternating flux passes through second connector
12 the second magnetic part 1223, and then second coil 1222 is made to generate induced current, the induced current to described second
Second conversion module 1252 is converted into direct current in connector 12, and reaches the second control module 1251, the second control mould
Block 1251 controls the signal radiated element 126 and emits optical signal, the second induction module 1162 sense of first connector 11
The optical signal should be arrived, and is sent to the first control module 1155, first control module 1155 controls the first switch
1156 second of closing, make the alternating current of first connector 11 repeat the above process continual communication power supply, and described second connects
The sustainable reception electric current of fitting 12 is to power supply unit.
Wherein, when the first switch 1156 is closed for the first time, this closed state is only maintained in a flash, to ensure the second company
Fitting 12 can emit optical signal；After first connector 11 receives the optical signal of the second connector 12 transmitting, institute
Second of first switch 1156 closing is stated, this closed state is continuously off state, until optical signal disappears.
The first switch 1156 closing be twice in order to more accurately judge the second connector 12 whether connection, with efficient
Power supply.Because of the case where in actual use, touching the first 11 first induction module 1161 of connector there are chaff interferent,
In such cases, the first switch 1156 can occur to close for the first time, but chaff interferent can not emit corresponding optical signal,
So 1,156 second of first switch closing can not be stimulated, the connection of 11 circuit of the first connector can not achieve, first connects
Fitting 11 reduces unnecessary energy loss still in safe standby state, also reduces energy and assembles in the first connector 11
Increase safety in utilization.
