[0037] This application provides an electronic device 100, which includes, but is not limited to, laptops, tablets, desktop computers, or smart cars, etc. The specific type of electronic device 100 is not limited here.

[0038] Figure 1 This is a schematic diagram of the structure of the electronic device 100 according to an embodiment of this application. See also Figure 1 As shown, the electronic device 100 in this embodiment of the application includes a first TYPE-C interface 110, a universal serial bus controller 121, a wired local area network controller 131, and a first controller 141.

[0039] The first Type-C interface 110 includes a first pin group 111, a second pin group 112, and a detection pin 113. The detection pin 113 is configured to generate a first signal when the target connector 200 is connected to the first Type-C interface 110 via its own second Type-C interface 210 in a preset manner. The target connector 200 includes a network interface 231 connected to the second Type-C interface 210 and at least one USB interface 221. Figure 3As shown. Optionally, the network interface 231 may include, but is not limited to, an RJ45 interface or an RJ11 interface, etc. Optionally, the USB interface 221 may include, but is not limited to, a USB TYPE-A interface, a USB TYPE-B interface, a USB TYPE-C interface, etc.

[0040] Optionally, the preset method may include connecting the first TYPE-C interface 110 to the second TYPE-C interface 210 in a preset direction. For example, both the first TYPE-C interface 110 and the second TYPE-C interface 210 include an A side and a B side. When the A side of the first TYPE-C interface 110 is connected to the A side of the second TYPE-C interface 210, and the B side of the first TYPE-C interface 110 is connected to the B side of the second TYPE-C interface 210, it can be considered that the second TYPE-C interface 210 is connected to the first TYPE-C interface 110 in a preset manner. At this time, the detection pin 113 generates a first signal.

[0041] A Universal Serial Bus (USB) controller 121 is connected to the first pin group 111 via a first switch unit 122. The USB controller 121 is used for serial communication based on the Universal Serial Bus protocol. A wired local area network (LAN) controller 131 is connected to the second pin group 112 via a second switch unit 132. The LAN controller 131 is used for wired network communication based on the Ethernet protocol. Optionally, both the first switch unit 122 and the second switch unit 132 can be formed using signal switch chips.

[0042] The first controller 141 is connected to the detection pin 113, the first switch unit 122, and the second switch unit 132, respectively. When the first signal is received, the first controller 141 is configured to activate the first switch unit 122 and the second switch unit 132, enabling the Universal Serial Bus controller 121 to connect to the USB interface 221 of the target connector 200 via the first pin group 111, forming a first communication channel conforming to the Universal Serial Bus protocol. Simultaneously, the wired LAN controller 131 is connected to the network interface 231 of the target connector 200 via the second pin group 112, forming a second communication channel conforming to the Ethernet protocol. Optionally, the first controller 141 can be formed, for example, by an embedded controller; alternatively, it can be formed by other components with control functions in the electronic device 100, such as a southbridge chip.

[0043] In use, the second TYPE-C interface 210 of the target connector 200 can be plugged into the first TYPE-C interface 110 in a preset manner. The detection pin 113 sends a first signal to the first controller 141. The first controller 141 turns on the first switch unit 122 and the second switch unit 132. The universal serial bus controller 121 is connected to the USB interface 221 of the target connector 200 through the first pin group 111 of the first TYPE-C interface 110. The wired local area network controller 131 is connected to the network interface 231 of the target connector 200 through the second pin group 112 of the first TYPE-C interface 110.

[0044] At this time, electronic device 100 connects to the wired local area network (LAN) through the network interface 231 of the target connector 200. Since the wired LAN controller 131 is mounted on electronic device 100, and electronic device 100 has a fixed MAC address, it can meet the requirement of binding a MAC address to a fixed IP address. Simultaneously, electronic device 100 can also connect to external devices or other electronic devices 100 through the USB interface 221 of the target connector 200 for serial communication.

[0045] Cooperate Figure 1 and Figure 2As shown, in some embodiments, the first pin group 111 includes at least TX+, TX-, RX+, RX-, VBUS, D+, D-, CC, and GND pins. The second pin group 112 includes at least TX+, TX-, RX+, RX-, SBU1, SBU2, D+, and D- pins. Optionally, the first TYPE interface may include a side A and a side B. Side A may have twelve pins, A1 to A12, which may be GND, TX1+, TX1-, VBUS, CC1, D+, D-, SBU1, VBUS, RX2-, RX2-, and GND pins, respectively. Side B can be configured with twelve pins, from B1 to B12, which can be GND, TX2+, TX2-, VBUS, CC2, D+, D-, SBU2, VBUS, RX1-, RX1-, and GND, respectively. Detection pin 113 can be formed from the GND pin at position A1. The first pin group 111 can include the TX1+, TX1-, VBUS, CC1, D+, and D- pins from side A, and the RX1- and RX1+ pins from side B. The second pin group 112 can include the SBU1, RX2-, and RX2- pins from side A, and the TX2+, TX2-, D+, D-, and SBU2 pins from side B. Thus, Ethernet communication and serial communication can be performed simultaneously through this first TYPE-C interface 110 without interference. In addition, the first TYPE-C interface 110 also has the functions of a regular TYPE-C interface and can be connected to a regular TYPE-C interface.

[0046] For example, taking the network interface 231 as an example of using an RJ45 interface, the connection relationship between some pins of the universal serial bus controller 121 and the pins in the first pin group 111, the connection relationship between the pins of the wired local area network controller 131 and the second pin group 112, and the connection relationship between the first controller 141 and the detection pin 113 can be shown in the following table.

[0047] Table 1

[0048]

[0049] In some embodiments, the detection pin 113 is formed through a GND pin. When the second TYPE-C interface 210 is connected to the first TYPE-C interface 110 in a preset manner, the detection pin 113 switches from a high potential to a low potential to generate the first signal. Optionally, the potential of the GND pin can be pulled high by the motherboard of the electronic device 100, so that when the first TYPE-C interface 110 is not connected to the second TYPE-C interface 210 or is not connected to the second TYPE-C interface 210 in a preset manner, the GND pin is at a high potential. When the second TYPE-C interface 210 is connected to the first TYPE-C interface 110 in a preset manner, the potential of the GND pin is pulled low, switching to a low potential. At this time, the first controller 141 turns on the first switch unit 122 and the second switch unit 132. The structure is simple and easy to implement.

[0050] In some embodiments, the first switch unit 122 is configured to be normally open, and the second switch unit 132 is configured to be normally closed. Thus, when the first TYPE-C interface 110 is not connected to any other TYPE-C interface, the first switch unit 122 connects the Universal Serial Bus controller 121 and the first pin group 111, while the second switch unit 132 switches the wired LAN controller 131 and the second pin group 112. When a user plugs a conventional TYPE-C interface into the first TYPE-C interface 110, the first controller 141 does not need to perform switching control, and the conventional TYPE-C interface can be connected to the first TYPE-C interface 110. When the second Type-C interface 210 is incorrectly connected to the first Type-C interface 110, the first controller 141 does not need to perform switching control, thus avoiding connection errors in the wired LAN controller 131. The first controller 141 only needs to activate the second switch unit 132 when the second Type-C interface 210 is correctly connected to the first Type-C interface 110. This simplifies the control logic of the first controller 141 and prevents data transmission errors in the wired LAN controller 131.

[0051] In some embodiments, the electronic device 100 further includes a prompting device 142 connected to the first controller 141; the detection pin 113 is further configured to send a second signal to the first controller 141 when the target connector 200 is not detected or the second TYPE-C interface 210 is not connected to the first TYPE-C interface 110 in a preset manner; the first controller 141 is further configured to control the prompting device 142 to perform a prompting operation when it receives the second signal. Optionally, the prompting device 142 includes, but is not limited to, an indicator light, a buzzer, a vibrator, or a display. For example, when the first TYPE-C interface 110 is idle, connected to a regular TYPE-C interface, or when the second TYPE-C interface 210 is correctly plugged into the first TYPE-C interface 110, the first controller 141 can control the indicator light to display green. When the second TYPE-C interface 210 is incorrectly plugged into the first TYPE-C interface 110, the first controller 141 can control the indicator light to display red to remind the user that the second TYPE-C interface 210 is inserted in the wrong direction.

[0052] This application also provides a connector 200 for connection to the electronic device 100 as described in any of the above embodiments. Figure 3 This is a structural block diagram of the connector 200 according to an embodiment of this application. See also... Figure 3 As shown, the connector 200 in this embodiment includes a second TYPE-C interface 210, a network interface 231, and at least one USB interface 221; the second TYPE-C interface 210 includes a third pin group 211 connected to the USB interface 221 and a fourth pin group 212 connected to the network interface 231.

[0053] The third pin group 211 corresponds to the first pin group 111, and the fourth pin group 212 corresponds to the second pin group 112. The number of pins in the third pin group 211 and the first pin group 111 may be the same or different. Similarly, the number of pins in the fourth pin group 212 and the second pin group 112 may be the same or different. For example, the number of pins in the third pin group 211 may be greater than the number of pins in the first pin group 111.

[0054] Optionally, the network interface 231 may include, but is not limited to, an RJ45 interface or an RJ11 interface, etc. Optionally, the USB interface 221 may include, but is not limited to, a USB Type-A interface, a USB Type-B interface, a USB Type-C interface, etc.

[0055] When the second TYPE-C interface 210 is connected to the first TYPE-C interface 110 in a preset manner, the third pin group 211 is connected to the first pin group 111, the fourth pin group 212 is connected to the second pin group 112, and the detection pin 113 is connected to the ground pin of the second TYPE-C interface 210 and generates the first signal.

[0056] Optionally, the ground pin of the second TYPE-C interface 210 can be pulled low or high to raise the potential of the detection pin 113, causing the detection pin 113 to send a first signal to the first controller 141. The first controller 141 can then activate the first switching unit 122 and the second switching unit 132. At this time, the universal serial bus controller 121 can communicate with the USB interface 221, and the wired LAN controller 131 can communicate with a network interface 231, such as an RJ45 interface. When the user plugs the network cable into the network interface 231 of the connector 200, the electronic device 100 can perform wired network communication based on the Ethernet protocol. Moreover, since the wired LAN controller 131 is located on the electronic device 100, the electronic device 100 has a MAC address, which can meet the usage requirements of binding the MAC address to a fixed IP address. The user can also plug external devices or other electronic devices 100 into the USB interface 221 of the connector 200, and they can also perform serial communication synchronously without interference.

[0057] Cooperate Figure 3 and Figure 4 As shown, in some embodiments, the third pin group 211 includes at least the TX+ pin, TX- pin, RX+ pin, RX- pin, VBUS pin, D+ pin, D- pin, CC pin, and GND pin.

[0058] Optionally, the second TYPE interface may include a side A and a side B. Side A may have twelve pins, A1 to A12, which may be GND, TX1+, TX1-, VBUS, CC1, D+, D-, SBU1, VBUS, RX2-, RX2-, and GND, respectively. Side B may have twelve pins, B1 to B12, which may be GND, TX2+, TX2-, VBUS, CC2, D+, D-, SBU2, VBUS, RX1-, RX1-, and GND, respectively.

[0059] The third pin group 211 may include the GND pin, TX1+ pin, TX1- pin, VBUS pin, CC1 pin, D+ pin, D- pin, and GND pin on side A, and the GND pin, VBUS pin, CC2 pin, VBUS pin, RX1- pin, RX1- pin, and GND pin on side B. The second pin group 112 may include the SBU1 pin, RX2- pin, and RX2- pin on side A, and the TX2+ pin, TX2- pin, D+ pin, D- pin, and SBU2 pin on side B. Thus, Ethernet communication and serial communication can be performed simultaneously through the first TYPE-C interface 110 without interference. Furthermore, the first TYPE-C interface 110 also has the functionality of a conventional TYPE-C interface and can be connected to a conventional TYPE-C interface.

[0060] In some embodiments, the connector 200 includes a plurality of USB interfaces 221, which are connected to the third pin group 211 via an adapter 223; the network interface 231 is connected to the fourth pin group 212 via a network filter 232, which is used to filter out noise to improve communication quality. For example, the connector 200 may include two Type-A interfaces and one third Type-C interface, which can be connected to the third pin group 211 via the adapter 223 (HUB). This expands the number of USB interfaces 221.

[0061] In some embodiments, the third pin group 211 includes at least a CC pin and a VBUS pin. The CC pin of the USB interface 221 is connected to the fast charging unit 226 via a power conversion circuit 224. The fast charging unit 226 is connected to the CC pin of the third pin group 211. The VBUS pin of the USB interface 221 is connected to the VBUS pin of the third pin group 211 via the power conversion circuit 224. The power conversion circuit 224 is used to change power parameters; for example, it can be used to adjust voltage, current, or perform AC / DC conversion. Optionally, the power conversion circuit 224 may include, for example, a BUCK-BOOST circuit or other circuits capable of adjusting power parameters. The fast charging unit 226 is configured to interact with the electronic device 100 based on a power transfer protocol, controlling the USB interface 221 to transmit power to the electronic device 100 based on the power transfer protocol. Thus, the connector 200 also enables fast charging functionality, further expanding its usability and improving the user experience.

[0062] Taking the connector 200, which includes two TYPE-A interfaces and one third TYPE-C interface, as an example, the two TYPE-A interfaces and the third TYPE-C interface can be connected to the third pin group 211 via an adapter 223 (HUB). Simultaneously, the CC1 and VBUS pins of the third TYPE-C interface can be connected to the power distribution circuit 224. The power distribution circuit 224 can be connected to the VBUS pin of the third pin group 211 via the adapter 223, and the power distribution circuit 224 is connected to the CC1 pin of the third pin group 211 via a fast charging unit 226. The fast charging unit 226 can communicate with the electronic device 100 via the CC1 pin of the third pin group 211 and can control the power distribution circuit 224 to transmit power to the electronic device 100 via the VBUS pin of the third pin group 211.

[0063] Optionally, a third switch unit 222 may be provided between the power supply circuit 224 and the third TYPE-C interface. The third switch unit 222 can connect or disconnect the power supply circuit 224 and the third TYPE-C interface. For example, if it is determined that the electronic device 100 supports fast charging and the power adapter connected to the third TYPE-C interface also supports fast charging, the third switch unit 222 can be turned on; otherwise, the third switch unit 222 can be turned off.

[0064] Optionally, the transformer circuit 224 is connected to the VBUS pin of the third pin group 211 via a voltage regulator circuit 225. The voltage regulator circuit 225 regulates the VBUS pin voltage, which helps improve charging efficiency and safety. Optionally, the voltage regulator circuit 225 can be formed using, for example, a SY8089 chip or other voltage regulator circuits 225. The type of voltage regulator circuit 225 is not limited here, as long as it can stabilize the voltage of the VBUS pin.

[0065] The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. The scope of protection of this application is defined by the claims.
