In some alternative embodiments of the present utility model, fig. 12 is an exemplary structural schematic diagram of a connector 10 provided in an exemplary embodiment of the present utility model. Wherein D1 to D7 represent body diodes of the first switching circuit 141, the second switching circuit 142, the third switching circuit 143, the fourth switching circuit 152, the fifth switching circuit 153, the sixth switching circuit 154, and the seventh switching circuit 155, respectively. Each of the switching circuits is based on a MOSFET implementation, the first switching circuit 141, the fourth switching circuit 152 and the fifth switching circuit 153 are all P-channel MOSFETs, the second switching circuit 142, the third switching circuit 143, the sixth switching circuit 154 and the seventh switching circuit 155 are all N-channel MOSFETs, and in practical applications, the types of MOSFETs may be set according to practical requirements, and are not limited to the setting mode of this example. D8 denotes a zener diode 1441, R1 to R14 denote resistors, C1 to C7 denote capacitors, and each resistor and capacitor serve as an auxiliary device in a corresponding switching circuit, assisting each switching circuit to perform a corresponding switching function better. For example, part of the auxiliary devices may act as a filter, making the transmitted signal smoother; part of auxiliary devices can act as a voltage reducing function to obtain the required voltage; etc. GND represents the reference voltage terminal Vref, and other symbols are as described above, and are not repeated here.

In the case that the external device 20 to which the interface 11 is coupled is a power adapter, and the power adapter is connected to an external power source, the controller 30 outputs a first control signal through the control terminal 12. In this example, the first control signal is a low level signal (for example, may be 0V). The interface 11 inputs a power supply, so that the voltage at the first end D11 of the first switch circuit 141 is vbus_in, and under the action of vbus_in, the body diode D1 of the first switch circuit 141 is turned on, and the voltage v12=vbus_in-VD 1 at the second end S12 of the first switch circuit 141 represents a voltage drop caused by the body diode D1. The voltage of the third terminal G33 of the third switch circuit 143 (i.e., the voltage of the first control signal) and the voltage of the second terminal S32 (i.e., the reference voltage) do not satisfy the on condition of the third switch circuit 143, and the third switch circuit 143 is turned off. The voltage at the battery terminal 13 is V12, so that the voltage at the first terminal V1 of the voltage stabilizing circuit 144 is V12, and by the action of the voltage stabilizing circuit 144, the voltage at the first common node m1 (i.e. the voltage at the third terminal G23 of the second switching circuit 142) and the voltage at the second terminal S22 of the second switching circuit 142 (i.e. the reference voltage) meet the conduction condition of the second switching circuit 142, and the first terminal D21 of the second switching circuit 142 and the second terminal S22 are conducted, so that the voltage at the third terminal G13 (i.e. the reference voltage) of the first switching circuit 141 and the voltage at the second terminal S12 (i.e. V12) meet the conduction condition of the first switching circuit 141, the first terminal D11 of the first switching circuit 141 and the second terminal S12 are conducted, and the body diode D1 IN the first switching circuit 141 is shorted, and the first switching circuit 141 completely transmits the power (the voltage at the interface 11 is vbus_in) to the battery terminal 13 for charging the battery 40. Meanwhile, the sixth switching circuit 154 and the seventh switching circuit 155 are turned off by the first control signal and the reference voltage. The sixth switching circuit 154 is turned off such that the voltages of the third terminal G53 and the second terminal S52 of the fifth switching circuit 153 cannot satisfy the on condition of the fifth switching circuit 153, and the fifth switching circuit 153 is turned off. EN in the current limiting module 151 indicates an enable terminal, high level enable, low level close, and thus, the current limiting module 151 is closed under the action of the first control signal. The fifth switching circuit 153 is turned off to prevent the power at the battery terminal from being transmitted to the current limiting module 151, thereby protecting the current limiting module 151. The seventh switching circuit 155 is turned off, so that the voltages at the third end G43 and the second end S42 of the fourth switching circuit 152 cannot meet the conduction condition of the fourth switching circuit 152, and therefore the fourth switching circuit 152 is turned off, so that the power input by the interface 11 is prevented from being transmitted to the current limiting module 151, and the current limiting module 151 is further protected.

In the case that the external device 20 coupled to the interface 11 is a data device of a preset type, the controller 30 outputs a second control signal to the control terminal 12, where the second control signal is a high level signal (for example, may be 1V, 3V, etc.). The voltage of the output power of the battery terminal 13 is VBUS. The sixth switching circuit 154, the seventh switching circuit 155, and the third switching circuit 143 are turned on by the second control signal and the reference voltage. The turning on of the third switch circuit 143 turns off the second switch circuit 142, and thus turns off the first terminal D11 and the second terminal S12 of the first switch circuit 141, so that the power source with the voltage VBUS cannot be directly transmitted to the data device of the preset type through the first switch circuit 141. Conduction of the sixth switching circuit 154 turns on the fifth switching circuit 153, passing VBUS power to the current limiting module 151. Meanwhile, the current limiting module 151 is enabled under the action of the second control signal, and limits the current of VBUS output through the battery terminal 13 to be the power of the preset current, and outputs the current through the first terminal D1, so that the body diode D4 of the fourth switching circuit 152 is turned on. Since the turn-on of the seventh switching circuit 155 causes the voltage of the third terminal G43 (i.e., the reference voltage) and the voltage of the second terminal S42 of the fourth switching circuit 152 to satisfy the turn-on condition of the fourth switching circuit 152, the first terminal D41 and the second terminal S42 of the fourth switching circuit 152 are turned on, the body diode D4 of the fourth switching circuit 152 is shorted, and the fourth switching circuit 152 transmits the power of the preset current outputted through the first terminal D1 of the current limiting module 151 to the interface 11, thereby supplying power to the data device of the preset type.
