[0069] In order to better understand the technical solution of the present application, the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0070] It should be clear that the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the protection scope of the present application.

[0071] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms of "a", "the" and "said" used in the embodiments of the present application and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise.

[0072] It should be understood that the term " / and" used herein is only a description of the associated relationship of the associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " herein generally represents an "or" relationship between the associated objects before and after.

[0073] Before describing the embodiments of the present application, the related technologies and their technical problems will be described first. Figure 1 Schematic diagram of a device in the related technology, as Figure 1As shown, a peripheral module S and a terminal product M are shown. Both the peripheral module S and the terminal product M include seven terminals, and the terminals can also be referred to as pins. The peripheral module S is provided with seven terminals S1 to S7 in order from top to bottom. The peripheral module S further includes a peripheral module S8, and the peripheral module S8 includes four ports S81 to S84, which are respectively used to transmit the power supply voltage VCC, the second differential signal D-, the first differential signal D+, and the ground voltage GND. S81 is electrically connected to S4, S82 is electrically connected to S3 and S5, S83 is electrically connected to S2 and S6, and S84 is electrically connected to S1 and S7. The terminal product M is provided with seven terminals M1 to M7 in order from top to bottom, which are respectively used to transmit GND, D+, D-, VCC, D-, D+, and GND. When the peripheral module S is connected to the terminal product M, regardless of whether it is a forward plug or a reverse plug between the seven terminals on the terminal product M side and the seven terminals on the peripheral module S side, the correct signal can be transmitted, thus realizing the forward and reverse plug function. However, this will result in a relatively large number of terminals for plugging, resulting in a large occupied space and high cost of the device.

[0074] In order to reduce the occupied space of the device and lower the cost, the embodiments of the present application provide a system, a first electronic device, and a second electronic device. Figure 2 As shown in the structural schematic diagram of a system provided by an embodiment of the present application, Figure 2 As shown, the system A includes a first electronic device B and a second electronic device C.

[0075] The first electronic device B includes: a first connector B1, and the first connector B1 includes a first terminal B11, a second terminal B12, a third terminal B13, a fourth terminal B14, and a fifth terminal B15 arranged in sequence. The first electronic device B further includes a first signal end B2, a second signal end B3, a first voltage end B4, a second voltage end B5, and a switching circuit B6. The first voltage end B4 is used to provide a first voltage, and the second voltage end B5 is used to provide a second voltage. First, taking the first voltage as a low level and the second voltage as a high level as an example for illustration, the first voltage end B4 is the ground voltage GND with a low level, the second voltage end B5 is the power supply voltage VCC with a high level. The first signal end B2 is used to transmit the first differential signal, and the second signal end is used to transmit the second differential signal. The first voltage end B4 is electrically connected to the third terminal B13.

[0076] The second electronic device C includes: a second connector C1, where the second connector C1 includes a sixth terminal C11, a seventh terminal C12, an eighth terminal C13, a ninth terminal C14, and a tenth terminal C15 arranged in sequence; the sixth terminal C11 is electrically connected to the eighth terminal C13; a functional device C2, where the functional device C2 includes a third signal terminal C21, a fourth signal terminal C22, a third voltage terminal C23, and a fourth voltage terminal C24, the third signal terminal C21 is electrically connected to the seventh terminal C12, the fourth signal terminal C22 is electrically connected to the ninth terminal C14, the third voltage terminal C23 is electrically connected to the sixth terminal C11 and the eighth terminal C13, and the fourth voltage terminal C24 is electrically connected to the tenth terminal C15; the third signal terminal C21 is used to transmit a first differential signal D+, the fourth signal terminal C22 is used to transmit a second differential signal D-, the third voltage terminal C23 is used to transmit a first voltage, and the fourth voltage terminal C24 is used to transmit a second voltage.

[0077] As Figure 3 shown, when the first connector B1 and the second connector C1 are plugged in the forward direction, B11 - B15 are respectively connected to C11 - C15. Therefore, the first voltage terminal B4 is connected to the third voltage terminal C23 through the third terminal B13 and the eighth terminal C13 to achieve the transmission of GND, and the first voltage terminal B4 is connected to the first terminal B11 through the third terminal B13, the eighth terminal C13, and the sixth terminal C11. Therefore, the voltage of the first terminal B11 is GND, and the switching circuit B6 can determine that the first terminal B11 is connected to the first voltage terminal B4 according to the voltage of the first terminal B11 being GND. The switching circuit B6 is used to control the first signal terminal B2 to be connected to the second terminal B12 when the first terminal B11 is connected to the first voltage terminal B4, that is, to connect the first signal terminal B2 to the third signal terminal C21 through the second terminal B12 and the seventh terminal C12 to achieve the transmission of the first differential signal D+, control the second signal terminal B3 to be connected to the fourth terminal B14, that is, to connect the second signal terminal B3 to the fourth signal terminal C22 through the fourth terminal B14 and the ninth terminal C14 to achieve the transmission of the second differential signal D-, and control the second voltage terminal B5 to be connected to the fifth terminal B15, that is, to connect the second voltage terminal B5 to the fourth voltage terminal C24 through the fifth terminal B15 and the tenth terminal C15 to achieve the transmission of VCC. It can be seen that through the forward plugging between the first connector B1 and the second connector C1, the first electronic device B can supply power to the second electronic device C and achieve data transmission between the two.

[0078] As Figure 4As shown, when the first connector B1 and the second connector C1 are reversely plugged, B11 - B15 are respectively connected to C15 - C11. Therefore, the first voltage terminal B4 is connected to the third voltage terminal C23 through the third terminal B13 and the eighth terminal C13, realizing the transmission of GND. And the first voltage terminal B4 is connected to the fifth terminal B15 through the third terminal B13, the eighth terminal C13 and the sixth terminal C11. Therefore, the voltage of the fifth terminal B15 is GND. The switching circuit B6 can determine that the fifth terminal B15 is connected to the first voltage terminal B4 according to the fact that the voltage of the fifth terminal B15 is GND. The switching circuit B6 is used to control the first signal terminal B2 to be connected to the fourth terminal B14 when the fifth terminal B15 is connected to the first voltage terminal B4, that is, the first signal terminal B2 is connected to the third signal terminal C21 through the fourth terminal B14 and the seventh terminal C12, realizing the transmission of the first differential signal D+. The second signal terminal B3 is controlled to be connected to the second terminal B12, that is, the second signal terminal B3 is connected to the fourth signal terminal C22 through the second terminal B12 and the ninth terminal C14, realizing the transmission of the second differential signal D-. The second voltage terminal B5 is controlled to be connected to the first terminal B11, that is, the second voltage terminal B5 is connected to the fourth voltage terminal C24 through the first terminal B11 and the tenth terminal C15, realizing the transmission of VCC. It can be seen that through the reverse plugging between the first connector B1 and the second connector C1, the first electronic device B can also supply power to the second electronic device C and realize data transmission between the two.

[0079] In the embodiments of the present application, the first electronic device and the second electronic device can be in a connected state or in a to - be - connected state. The first electronic device includes but is not limited to computers, mobile phones, wearable devices, etc. The second electronic device includes but is not limited to pluggable camera devices, microphone devices, speaker devices, etc. The embodiments of the present application can be applied to any circuit, connector or interface that requires adaptive direction selection for power supply and signal channels. For example, the first electronic device includes a laptop computer and the second electronic device includes a pluggable camera device. The connection interface between the first electronic device and the second electronic device can be a Universal Serial Bus (USB) interface or other interfaces that use at least two ports for power supply and two ports for data transmission. The first electronic device is the master device among them, called Master or Host, and the second electronic device is the slave device among them, called Slave or Device.

[0080] The system, the first electronic device, and the second electronic device in the embodiments of the present application. Among them, the first electronic device includes 5 terminals. Taking the third terminal as the center of symmetry, the switching circuit can control the first voltage terminal to be connected to the first terminal and the second voltage terminal to be connected to the fifth terminal through the power supply polarity, or control the first voltage terminal to be connected to the fifth terminal and the second voltage terminal to be connected to the first terminal, so as to realize the adaptive switching of the power conduction path through the switching circuit. The switching circuit can control the first signal terminal to be connected to the second terminal and the second signal terminal to be connected to the fourth terminal through the power supply polarity, or control the first signal terminal to be connected to the fourth terminal and the second signal terminal to be connected to the second terminal, so as to realize the adaptive switching of the signal channel through the switching circuit. By adopting this solution, the power conduction path and the signal channel can be determined simultaneously through the power supply polarity, reducing the number of terminals of the first electronic device. Therefore, adaptive switching can be realized with very few devices, reducing the space occupied by the connection terminals in the first electronic device, thereby reducing the cost. The second electronic device includes 5 terminals, with the third signal terminal used to transmit the first differential signal, the fourth signal terminal used to transmit the second differential signal, the third voltage terminal used to transmit the first voltage, and the fourth voltage terminal used to transmit the second voltage, thereby reducing the space occupied by the terminals in the second electronic device, thereby reducing the cost.

[0081] In a possible implementation manner, as Figure 5 shown, Figure 5 is a schematic diagram of a first electronic device provided by an embodiment of the present application. The switching circuit B6 includes: a first switching module B61. The first switching module includes a selection signal terminal B611, and the selection signal terminal B611 is electrically connected to the first terminal B11.

[0082] As Figure 6 shown, when the first connector B1 and the second connector C1 are plugged in forward, the first terminal B11 and the selection signal terminal B611 are at the first voltage, such as GND. The first switching module B61 is used to control the first signal terminal B2 to be connected to the second terminal B12 and the second signal terminal B3 to be connected to the fourth terminal B14 when the selection signal terminal B611 is at the first voltage, such as GND. That is, through the first switching module B61, according to the first voltage GND of the selection signal terminal B611, the second terminal B12 transmits the first differential signal D+, and the fourth terminal B14 transmits the second differential signal D-, so as to realize the correct data transmission path when the connectors are plugged in forward. The switching circuit B6 further includes a second switching module B62. The second switching module B62 is used to control the second voltage terminal B5 to be connected to the fifth terminal B15 when the first terminal B11 is at the first voltage, such as GND. That is, through the second switching module B61, according to the first voltage GND of the first terminal B11, the second voltage VCC is provided for the fifth terminal B15, so as to provide the correct power supply path when the connectors are plugged in forward.

[0083] As Figure 7 shown, when the first connector B1 and the second connector C1 are reversely plugged, the fifth terminal B15 is the first voltage GND. The second switching module B62 is configured to, when the fifth terminal B15 is the first voltage GND, control the second voltage terminal B5 to be connected to the first terminal B11 to provide the second voltage VCC for the first terminal B11 and the selection signal terminal B611. That is, the second switching module B62 is used to provide the second voltage VCC for the first terminal B11 according to the first voltage GND of the fifth terminal B15, so as to provide a correct power supply path when the connectors are reversely plugged. The first switching module B61 is configured to, when the selection signal terminal B611 is the second voltage VCC, control the first signal terminal B2 to be connected to the fourth terminal B14 and control the second signal terminal B3 to be connected to the second terminal B12. That is, the first switching module B61 is used to transmit the second differential signal D- through the second terminal B12 and transmit the first differential signal D+ through the fourth terminal B14 according to the second voltage VCC of the selection signal terminal B611, so as to achieve a correct data transmission path when the connectors are reversely plugged.

[0084] In some embodiments, as Figure 5 shown, the first switching module B61 may include a double-pole double-throw switch.

As Figure 6 shown, when the selection signal terminal B611 is the first voltage, the first input terminal b01 is connected to the first output terminal b61, and the second input terminal b02 is connected to the third output terminal b63. As Figure 7 shown, when the selection signal terminal B611 is the second voltage, the first input terminal b01 is connected to the second output terminal b62, and the second input terminal b02 is connected to the fourth output terminal b64. It can be understood that the first switching module B61 can also be implemented by other circuits or the like. The first switching module B61 may also include a Universal Serial Bus (USB) switch. For example, the USB switch includes a USB2.0 switch or a USB3.0 switch. The specific implementation manner of the first switching module B61 in the embodiments of the present application is not limited, and the double-pole double-throw switch is only an example.

For example, the first voltage terminal B4 is a ground voltage GND, GND is, for example, 0V, and the second voltage terminal B5 is a high-level power supply voltage VCC, for example, 3.3V.

[0087] In some embodiments, as Figures 5 to 7 shown, the first switching unit Q1 and / or the second switching unit Q2 is a P-type transistor, for example, a P-channel metal oxide semiconductor field effect transistor (positive channel Metal Oxide Semiconducto, PMOS). One of the first end and the second end of the switching unit is the source electrode, and the other is the drain electrode. The control end is the gate electrode. The P-type transistor is a device that is turned on by a low level and turned off by a high level, that is, in response to a high level at the gate electrode, it is turned off between the source electrode and the drain electrode, and in response to a low level at the gate electrode, it is turned on between the source electrode and the drain electrode. The above respective resistor modules are resistor devices.

[0088] The following describes Figures 5 to 7 the specific working process and principle of the circuit in

[0089] As Figure 5 shown, when the first connector B1 is not plugged in, since the first terminal B11 and the fifth terminal B15 are floating, the first switching unit Q1 and the second switching unit Q2 do not meet the conduction conditions, so the channel is cut off. Both the first terminal B11 and the fifth terminal B15 maintain a weakly pulled-up high level due to the connection through a resistor to the second voltage terminal B5.

[0090] As Figure 6 shown, when the first connector B1 is plugged in positively with the second connector C1, since the first terminal B11 is connected to the first voltage terminal B4 through the second electronic device, the voltage of the first terminal B11 is pulled down. And since GND is strongly pulled down, the gate voltage of the second switching unit Q2 is pulled down, so that the second switching unit Q2 meets the conduction conditions and conducts. The high level of the second voltage terminal B5 provides VCC to the fifth terminal B15 through the conducting second switching unit Q2, and then provides VCC to the second electronic device through the tenth terminal C15. Additionally, GND is provided to the second electronic device through the eighth terminal C13, that is, a power supply path for the second electronic device is realized. At this time, the gate voltage of the first switching unit Q1 remains pulled up, so it remains in the cut-off state. Figure 6 The thickened path in the figure is the high-level path, that is, the VCC path, and the dotted path is the low-level path, that is, the GND path. The selection signal terminal B611 of the first switching module B61 is connected to the first terminal B11, so it is pulled down, making the first input terminal b01 connected to the first output terminal b61, and the second input terminal b02 connected to the third output terminal b63, so that the signal channels of the first signal terminal B2 and the second signal terminal B3 are correctly connected to the second electronic device, that is, a data signal path for the second electronic device is realized.

[0091] As Figure 7 shown, when the first connector B1 is plugged in reversely with the second connector C1, since the fifth terminal B15 is connected to the first voltage terminal B4 through the second electronic device, the voltage of the fifth terminal B15 is pulled down. And since GND is strongly pulled down, the gate voltage of the first switching unit Q1 is pulled down, so that the first switching unit Q1 meets the conduction conditions and conducts. The high level of the second voltage terminal B5 provides VCC to the first terminal B11 through the conducting first switching unit Q1, and then provides VCC to the second electronic device through the tenth terminal C15. Additionally, GND is provided to the second electronic device through the eighth terminal C13, that is, a power supply path for the second electronic device is realized. At this time, the gate voltage of the second switching unit Q2 remains pulled up, so it remains in the cut-off state. Figure 7The thickened path is the high-level path, i.e., the VCC path, and the dotted-dashed path is the low-level path, i.e., the GND path. The selection signal terminal B611 of the first switching module B61 is connected to the first terminal B11 and is thus pulled high, causing the first input terminal b01 to be connected to the second output terminal b62 and the second input terminal b02 to be connected to the fourth input terminal b64, enabling the signal channels of the first signal terminal B2 and the second signal terminal B3 to be correctly connected to the second electronic device, i.e., realizing the data signal path for the second electronic device.

[0092] It can be seen that the paths of the first differential signal D+ and the second differential signal D- will be adaptively switched by the first switching module B61 according to the detection result of the plugging direction of the connector. The two outermost terminals B11 and B15 in the first connector B1 serve as the positive path of the VCC power supply and the negative path of the GND power supply respectively. Through the second switching module B62, it is detected which terminal among B11 and B15 is connected to GND, thereby determining the plugging direction of the connector, and the power supply channel of the other terminal is switched according to the plugging direction.

[0093] As Figures 5 to 7 shown, on the one hand, the third resistor module R3, the fourth resistor module R4, and the fifth resistor module R5 can buffer between two components, reducing the impact of electrostatic from the pins on the devices in the circuit. For example, as Figure 5 shown, the fourth resistor module R4 can buffer between the gate of the second switching unit Q2 and the pin of the first terminal B11, capable of reducing the voltage impact of electrostatic from the pin of the first terminal B11 on the gate of the second switching unit Q2. On the other hand, the resistance values of R3 to R5 can be related to the parameters of the transistor. For example, the resistance value of the corresponding third resistor module R3 can be set according to the conduction threshold of Q1 to cooperate with the first resistor module R1 for voltage division, enabling the gate of Q1 to control the on and off states according to the voltage after voltage division. Assuming VCC = 3.3V and GND = 0V, in the Figure 6 shown state, the gate voltage of Q1 is 0.7V through the voltage division of R1 and R3, still belonging to the low level and less than the threshold voltage of Q1. At this time, Q1 can be controlled to turn off. The voltage division principle of R4 is similar and will not be elaborated. Generally, the resistance value of R3 is less than that of R1, and the resistance value of R4 is less than that of R2.

[0094] It can be seen that the third resistor module R3, the fourth resistor module R4, and the fifth resistor module R5 are all optional resistor modules. For the second switching module B62, any one or more of the third resistor module R3, the fourth resistor module R4, and the fifth resistor module R5 can also be omitted. For example Figure 8As shown, the control terminal of the first switch unit Q1 can be directly electrically connected to the fifth terminal B15, the gate of the second switch unit Q2 can be directly electrically connected to the first terminal B11, and the selection signal terminal B611 can be directly electrically connected to the first terminal B11. Figure 8 The working principle of the circuit structure shown is the same as that of Figure 5 For example, when the first connector B1 is inserted forward with the second connector C1, the gate of Q2 is at a low level to control Q2 to conduct, and the gate of Q1 is at a high level to control Q1 to cut off; when the first connector B1 is inserted reversely with the second connector C1, the gate of Q1 is at a low level to control Q1 to conduct, and the gate of Q2 is at a high level to control Q2 to cut off.

[0095] In some embodiments, as Figures 9 to 11 shown, the first voltage is at a high level and the second voltage is at a low level. For example, the first voltage terminal B4 is the power supply voltage VCC at a high level, VCC is 3.3V for example, and the second voltage terminal B5 is the ground voltage GND at a low level, GND is 0V for example. That is to say, the first voltage terminal B4 is used to provide VCC, the second voltage terminal B5 is used to provide GND, the third voltage terminal C23 is used to transmit VCC, and the fourth voltage terminal C24 is used to transmit GND. Figures 9 to 11 The embodiment shown is similar to that of Figures 2 to 4 shown, the difference is only that VCC and GND are exchanged. In the embodiment shown in Figures 2 to 4 GND is transmitted through the terminal in the middle of the first connector B1, and the forward or reverse insertion of the second connector C1 is judged by the GND voltage on the terminals at both ends, and then the corresponding power supply path and signal path are provided according to the insertion direction; in the embodiment shown in Figures 9 to 11 VCC is transmitted through the terminal in the middle of the first connector B1, and the forward or reverse insertion of the second connector C1 is judged by the VCC voltage on the terminals at both ends, and then the corresponding power supply path and signal path are provided according to the insertion direction. The specific process and principle are similar and will not be elaborated here.

[0096] In some embodiments, as Figures 12 to 14As shown, the first voltage is at a low level and the second voltage is at a high level. For example, the first voltage terminal B4 is the power supply voltage VCC at a high level, such as 3.3V, and the second voltage terminal B5 is the ground voltage GND, and GND is, for example, 0V. The first switching unit Q1 and / or the second switching unit Q2 is an N-type transistor, such as an N-channel metal oxide semiconductor field effect transistor (Negative channel Metal Oxide Semiconducto, NMOS). One of the first end and the second end of the switching unit is the source electrode, and the other is the drain electrode, and the control end is the gate electrode. The N-type transistor is a device that conducts when the level is high and cuts off when the level is low, that is, in response to the low level of the gate electrode, the conduction between the source electrode and the drain electrode is cut off, and in response to the high level of the gate electrode, the conduction between the source electrode and the drain electrode is turned on. Figure 12 Similar to Figure 8 the structure shown, the difference is only that the voltages provided by the first voltage terminal B4 and the second voltage terminal B5 are exchanged, and Q1 and Q2 are changed from P-type transistors to N-type transistors. The specific working process and principle of the circuit shown below will be described. Figures 12 to 14 the circuit shown will be described.

[0097] As Figure 12 shown, when the first connector B1 is not plugged in, since the first terminal B11 and the fifth terminal B15 are floating, the first switching unit Q1 and the second switching unit Q2 do not meet the conduction conditions, so the channel is cut off.

[0098] As Figure 13 shown, when the first connector B1 is plugged in positively with the second connector C1, since the first terminal B11 is connected to the first voltage terminal B4 through the second electronic device, the voltage of the first terminal B11 is pulled up, and since the first terminal B11 is directly connected to the gate electrode of the second switching unit Q2, the gate voltage of the second switching unit Q2 is pulled up, so that the second switching unit Q2 meets the conduction conditions and conducts. The low level of the second voltage terminal B5 provides GND to the fifth terminal B15 through the conducting second switching unit Q2, and then provides GND to the second electronic device through the tenth terminal C15. In addition, VCC is provided to the second electronic device through the eighth terminal C13, that is, the power supply path for the second electronic device is realized. At this time, the gate voltage of the first switching unit Q1 remains pulled low, so it remains in the cut-off state. Figure 13 The thickened path in [] is the high-level path, that is, the VCC path, and the dotted path is the low-level path, that is, the GND path. The selection signal terminal B611 of the first switching module B61 is connected to the first terminal B11, so it is pulled up, making the first input terminal b01 connected to the first output terminal b61, and the second input terminal b02 connected to the third input terminal b63, so that the signal channels of the first signal terminal B2 and the second signal terminal B3 are correctly connected to the second electronic device, that is, the data signal path for the second electronic device is realized.

[0099] like Figure 14 As shown, when the first connector B1 and the second connector C1 are reversely plugged in, the fifth terminal B15 is connected to the first voltage terminal B4 through the second electronic device, so the voltage of the fifth terminal B15 is pulled up, and since the fifth terminal B15 is directly connected to the gate of the first switch unit Q1, the gate voltage of the first switch unit Q1 is pulled up, so that the first switch unit Q1 meets the turn-on condition and is turned on. The low level of the second voltage terminal B5 provides GND to the first terminal B11 through the turned-on first switch unit Q1, and then provides GND to the second electronic device through the tenth terminal C15. In addition, VCC is provided to the second electronic device through the eighth terminal C13, that is, the power supply path for the second electronic device is realized. At this time, the gate voltage of the second switch unit Q2 remains low, and therefore remains in the off state. Figure 14 The bold path is the high-level path, namely the VCC path, and the dotted-line path is the low-level path, namely the GND path. The select signal terminal B611 of the first switching module B61 is connected to the first terminal B11, thereby being pulled low. This connects the first input terminal b01 to the second output terminal b62, and the second input terminal b02 to the fourth input terminal b64. This ensures that the signal paths between the first signal terminal B2 and the second signal terminal B3 are properly connected to the second electronic device, thus completing the data signal path for the second electronic device.

[0100] exist Figures 12 to 14 On the basis of that, the first voltage terminal B4 is the high level power supply voltage VCC, the second voltage terminal B5 is the ground voltage GND, as shown in FIG. Figure 15 As shown, the gate of Q1 is electrically connected to the fifth terminal B15 through the third resistor module R3, the gate of Q2 is electrically connected to the first terminal B11 through the fourth resistor module R4, and the selection signal terminal B611 is electrically connected to the first terminal B11 through the fifth resistor module R5. Figure 15 The structure and Figure 5 The structure is similar to that of FIG. 1 , except that the voltages provided by the first voltage terminal B4 and the second voltage terminal B5 are swapped.

[0101] It should be noted that the above Figures 2 to 8 The embodiments are described with the first voltage terminal B4 being the ground voltage GND as an example. In other possible embodiments, the first voltage terminal B4 may also be other reference voltages, as long as a voltage difference with VCC is formed to provide a power path. Figures 9 to 15 The embodiments are described with the second voltage terminal B5 being the ground voltage GND as an example. In other possible embodiments, the second voltage terminal B5 may also be other reference voltages as long as a voltage difference with VCC is formed to provide a power path.

[0102] The embodiments of the present application do not limit the specific implementation manners of the above-mentioned first switch unit and second switch unit. For example, they can be various types of switching devices such as MOS transistors, bipolar transistors, load switches, etc.

[0103] In some embodiments, the second electronic device is a peripheral device that can be connected to the first electronic device. For example, the first electronic device is a laptop computer, and the second electronic device is a magnetically attached camera device. Figure 16 A schematic diagram of a plug-in provided by an embodiment of the present application, as Figure 16 shown, the laptop computer and the magnetically attached camera device are converted from a state to be connected to a connected state. Among them, Figure 16 the left half part shows the forward plug-in of the laptop computer and the magnetically attached camera device, Figure 16 the right half part shows the reverse plug-in of the laptop computer and the magnetically attached camera device. The laptop computer includes a screen part, and the top of the screen part includes a first connector B1; the bottom of the magnetically attached camera device includes a second connector C1, and the functional device C2 includes a camera. When the side of the camera is aligned with the screen side of the screen part, align the second connector C1 with the first connector B1 and slowly approach. The magnetically attached camera device will be automatically adsorbed by the magnetic force. After adsorption, the forward plug-in of the laptop computer and the magnetically attached camera device can be realized; when the side of the camera is aligned with the protective case side of the screen part, align the second connector C1 with the first connector B1 and slowly approach. The magnetically attached camera device will be automatically adsorbed by the magnetic force. After adsorption, the reverse plug-in of the laptop computer and the magnetically attached camera device can be realized. Thus, the laptop computer includes 5 terminals, and the magnetically attached camera device also includes 5 terminals. Whether the laptop computer and the magnetically attached camera device are plugged in forward or reversely, the laptop computer adaptively selects the corresponding power supply path and signal path to be connected to the magnetically attached camera device through extremely few devices, and reduces the space occupied by the laptop computer and the magnetically attached camera device, and also reduces the cost.
