【Embodiment】
Below in conjunction with the accompanying drawings and embodiment is further described the utility model：
As shown in Figure 1, the utility model it include connecting line, input interface 10 and output interface arranged on connecting line both ends
20, input interface 10 is used to be connected to Type-A interfaces or Type-C interfaces, that is, standard USB interface with charger 30, defeated
Outgoing interface 20, which is used to be connected with mobile phone, to use Micro-USB-B interfaces, Lightning interfaces or Type-C interfaces etc. to connect
One kind of mouth, specifically, using Type-C interfaces in the present embodiment.In charging wire shell is equipped with close to one end of output interface
Body, is equipped with control board in housing, control board including microprocessor 40, breaking device 50, current detecting unit 60, pull out
Except detection unit 70 and status indicator lamp 80.Sampling resistor is equipped with current detecting unit 60, sampling resistor collection signal is simultaneously
The ADC (analog-digital converter) inside microprocessor 40 is sent to detect the charging current of mobile phone.Pull out detection unit 70 and Wei Chu
Reason device 40 and output interface 20 are electrically connected and for detecting whether output interface 20 connects equipment.Specifically, breaking device 50 is
Power switch uses N-channel MOS FET, is controlled for out-put supply negative terminal.Microprocessor 40 makes closure/disconnection carry out the confession of mobile phone
Electrical circuit, breaking device 50 be arranged between output interface 20 and microprocessor 40 and respectively with microprocessor 40 and output interface 20
It is electrically connected.
When the upper mobile phone of charging wire connection charges, current detecting unit 60 sends the detection signal collected to microprocessor
40, the processing of microprocessor 40 judges whether mobile phone is fully charged, and microprocessor 40 is sent out to breaking device 50 after mobile phone is fully charged
Control signal is sent to make 50 disconnecting circuit of breaking device.Detection unit 70, which is pulled out, during breaking device 50 disconnects continues to monitor output
Whether interface 20 is connected with mobile phone, and mobile phone is disconnected with output interface 20 makes that monitoring signals, microprocessor can be sent to microprocessor 40
Sending control signal to breaking device 50 after the processing of device 40 makes 50 connection circuit of breaking device.Meanwhile control board is also connected with
Stateful indicator light 80, status indicator lamp 80 and microprocessor 40 are connected to the charged state and current supply circuit of instruction mobile phone
Off-state.
The foregoing is merely this patent preferred embodiment, not limits this patent scope, every using specification and attached
The equivalent structure or equivalent flow shift that figure content is made, is directly or indirectly used in other relevant technical fields, belongs to
