Referring to fig. 1, fig. 1 is a schematic diagram of an adapter (adapter)100 with multiple connectors according to a first embodiment of the present invention, in which the adapter 100 includes a first connector 102, two second connectors 104, 106, a power delivery controller 108 and a multiplexer 110, the power delivery controller 108 is coupled to the first connector 102 and the second connectors 104, 106, the multiplexer 110 is coupled to the power delivery controller 108, the first connector 102 and the second connectors 104, 106, the first connector 102 is a C-Type (Type C) connector of a Universal Serial Bus (USB), the second connector 104 is a Display Port (DP) connector, and the second connector 106 is a High Definition Multimedia Interface (HDMI) connector. In addition, the present invention is not limited to the adapter 100 comprising two second connectors 104, 106, that is, the adapter 100 may comprise more than two second connectors, for example, the adapter 100 may comprise a display port connector, a high-definition multimedia interface connector and a universal serial bus Type C (Type C) connector. In addition, as shown in fig. 1, the multiplexer 110 is coupled to the power transmission controller 108 through a general purpose input/output pin GPIOP, but the present invention is not limited to the multiplexer 110 being coupled to the power transmission controller 108 through a general purpose input/output pin GPIOP. In another embodiment of the present invention, the multiplexer 110 may be connected to an Integrated circuit bus (Inter-Integrated circuit)2C) Coupled to the power delivery controller 108. Additionally, in the following embodiments of the present invention, the present invention will utilize the 18 th pin of the hot plug technology disclosed in the prior art in the second connector 104 (the display port connector) and the 20 th pin of the second connector 104 (the power pin of the display port connector), and utilize the second connector 106 (the high-definition multimedia interface is connected to the high-definition multimedia interface)Connector) and the 18 th pin (the power pin of the hdmi connector) of the second connector 106, and VBUS (the power pin of the type C connector of the usb) of the first connector 102 (the type C connector of the usb).
Referring to fig. 2, fig. 2 is a schematic diagram illustrating a first electronic device 202 connected to the first connector 102 and a second electronic device 204 connected to the second connector 104. As shown in fig. 2, when the second electronic device 204 is connected to the second connector 104, the power transmission controller 108 may detect that the second connector 104 is connected to the second electronic device 204 and the second connector 106 is not connected to any electronic device according to the hot swap technique disclosed in the prior art, and the power transmission controller 108 may determine the type of the second connector 104 according to the pin definition of the display port connector or the pin definition of the hdmi connector. In more detail, since the first connector 102, the second connector 104 and the second connector 106 have different pin definitions under the hot plugging technique disclosed in the prior art, when one of the second connector 104 and the second connector 106 is connected to an electronic device, the power transmission controller 108 can detect that the one is connected to the electronic device according to the hot plugging technique disclosed in the prior art. That is, the power transmission controller 108 does not know in advance which of the second connectors 104, 106 is connected to the second electronic device 204, so when the second electronic device 204 is connected to the second connector 104, the power transmission controller 108 needs to detect that the second connector 104 is connected to the second electronic device 204 according to the hot plug technology disclosed in the prior art. At this time, because the first connector 102, the second connector 104 and the second connector 106 have different pin definitions under the hot plug technology disclosed in the prior art, when a first predetermined pin in the second connector 104 (i.e. the 18 th pin of the second connector 104 under the hot plug technology disclosed in the prior art) is enabled and the second connector 106 is not enabled at the 19 th pin of the hot plug technology disclosed in the prior art (because the second connector 106 is not connected to any electronic device), the power transmission controller 108 may determine that the second connector 104 is the display port connector according to the pin definition of the display port connector (because the 18 th pin defined by the pin of the display port connector is a hot plug detection pin). Then, the power transmission controller 108 still needs to determine whether each of the first electronic device 202 and the second electronic device 204 is a master (host) or slave (slave) device. Because the power transmission controller 108 receives a first power transmitted by the first electronic device 202 through the VBUS pin of the first connector 102 (the power pin of the C-Type connector of the usb), the power transmission controller 108 can determine that the first electronic device 202 is a first host (host), for example, the first electronic device 202 is a notebook computer having a C-Type (Type C) connector of the usb. In addition, since the second electronic device 204 does not transmit a second power to the power transmission controller 108 through the second connector 104, the power transmission controller 108 can determine that the second electronic device 204 is a second slave (slave) device according to the determination, for example, the second electronic device 204 is a monitor having a display port connector. After the power transmission controller 108 determines that the first electronic device 202 is the first master and determines that the second electronic device 204 is the second slave, the multiplexer 110 may control the first connection configuration between the first connector 102 and the second connector 104 according to the first determination result of the power transmission controller 108 and the type of the second connector 104 (i.e., the displayport connector). For example, the multiplexer 110 controls the USB Super Speed (Super Speed) pins SSTX1, SSRX1, SSTX2 and SSRX2 of the first connector 102 to be connected to the pins ML2, ML3, ML1 and ML0 of the second connector 104, respectively (as shown in table one), that is, the signal of the USB Super Speed pin SSTX1 of the first connector 102 can be transmitted to the pin ML2 of the second connector 104, and vice versa. Similarly, the signal of the USB superspeed pin SSRX1 of the first connector 102 can be transmitted to the pin ML3 of the second connector 104, the signal of the USB superspeed pin SSTX2 of the first connector 102 can be transmitted to the pin ML1 of the second connector 104, and the signal of the USB superspeed pin SSRX2 of the first connector 102 can be transmitted to the pin ML0 of the second connector 104. Therefore, when the first electronic device 202 is the first host and the second electronic device 204 is the second slave, the adapter 100 can be used as a Type C (Type C) connector/display port connector cable (Type C-to-DP cable) of a universal serial bus between the first electronic device 202 and the second electronic device 204 through the first connection configuration. In addition, the first electronic device 202 (the first host) and the second electronic device 204 (the second slave) may negotiate that the second connector 104 and the display port connector of the second electronic device 204 operate in a display port standby mode. In addition, those skilled in the art will appreciate that the superspeed pins SSTX1, SSRX1, SSTX2, and SSRX2 and pins ML2, ML3, ML1, and ML0 are differential signal pair pins. In addition, when the first electronic device 202 is connected to the first connector 102, the second electronic device 204 is connected to the second connector 104, the first electronic device 202 is the first host, and the second electronic device 204 is the second slave, the present invention is not limited to the first connection configuration. In addition, in another embodiment of the present invention, when the power transmission controller 108 receives the first power transmitted by the first electronic device 202 through the pin VBUS of the first connector 102, the power transmission controller 108 can transmit the first power to the second electronic device 204.

In another embodiment of the present invention, as shown in fig. 3, when a third electronic device 302 is connected to the first connector 102 and a fourth electronic device 304 is connected to the second connector 104, if the power transmission controller 108 receives a fourth power transmitted by the fourth electronic device 304 through a second predetermined pin of the second connector 104 (e.g. the power pin of the second connector 104 (i.e. the 20 th pin of the second connector 104)), the power transmission controller 108 determines that the fourth electronic device 304 is a fourth host, and determines that the second connector 104 is the display port connector according to the pin definition of the display port connector (because the 20 th pin defined by the pin of the display port connector is used for transmitting the fourth power), for example, the fourth electronic device 304 is a notebook computer having a display port connector. In addition, since the third electronic device 302 does not transmit a third power to the power transmission controller 108 through the first connector 102, the power transmission controller 108 can determine that the third electronic device 302 is a third slave device according to the third power, for example, the third electronic device 302 is a monitor having a universal serial bus Type C (Type C) connector. At this time, since the fourth electronic device 304 transmits the fourth power to the power transmission controller 108, the first predetermined pin of the second connector 104 (e.g., the hot plug detection pin of the second connector 104 (i.e., the 18 th pin of the second connector 104)) is turned off. After the power transmission controller 108 determines that the third electronic device 302 is the third slave and determines that the fourth electronic device 304 is the fourth master, the multiplexer 110 may control the second connection configuration between the first connector 102 and the second connector 104 according to the second determination result of the power transmission controller 108 and the type of the second connector 104 (i.e., the display port connector), for example, the multiplexer 110 controls the USB super speed (SuperSpeed) pins SSTX1, SSRX1, SSTX2 and SSRX2 of the first connector 102 to be respectively connected to the pins ML3, ML2, ML0 and ML1 of the second connector 104 (as shown in table two), that is, the signal of the USB super speed pin SSTX1 of the first connector 102 may be transmitted to the pin ML3 of the second connector 104, or vice versa. Similarly, the signal of the USB superspeed pin SSRX1 of the first connector 102 can be transmitted to the pin ML2 of the second connector 104, the signal of the USB superspeed pin SSTX2 of the first connector 102 can be transmitted to the pin ML0 of the second connector 104, and the signal of the USB superspeed pin SSRX2 of the first connector 102 can be transmitted to the pin ML1 of the second connector 104. Therefore, when the third electronic device 302 is the third slave device and the fourth electronic device 304 is the fourth master device, the adaptor 100 can be used as a Type C connector cable (DP-to-Type C cable) of a displayport connector/usb between the third electronic device 302 and the fourth electronic device 304 through the second connection configuration. In addition, the fourth electronic device 304 (the fourth master) and the third electronic device 302 (the third slave) may negotiate that the displayport connector of the second connector 104 and the fourth electronic device 304 is operated in the displayport standby mode. In addition, when the third electronic device 302 is connected to the first connector 102, the fourth electronic device 304 is connected to the second connector 104, the third electronic device 302 is the third slave device, and the fourth electronic device 304 is the fourth master device, the present invention is not limited to the second connection configuration. In addition, in another embodiment of the present invention, when the power transmission controller 108 receives the fourth power transmitted by the fourth electronic device 304 through the second predetermined pin of the second connector 104, the power transmission controller 108 can transmit the fourth power to the third electronic device 302.

As shown in fig. 4, if the power transmission controller 108 receives a fifth power transmitted by the fifth electronic device 402 via the VBUS pin of the first connector 102 (the power pin of the Type C connector of the usb), the power transmission controller 108 can accordingly determine that the fifth electronic device 402 is a fifth host, for example, the fifth electronic device 402 is a notebook computer having a Type C (Type C) connector of the usb. In addition, since the sixth electronic device 404 does not transmit a sixth power to the power transmission controller 108 through the second connector 106, the power transmission controller 108 can determine that the sixth electronic device 404 is a sixth slave device according to the sixth power, for example, the sixth electronic device 404 is a monitor having a hdmi connector. In addition, since the sixth electronic device 404 does not transmit the sixth power to the power transmission controller 108 through the second connector 106, and a third predetermined pin (i.e., the 19 th pin of the second connector 106) of the second connector 106 is enabled, the power transmission controller 108 can determine that the second connector 106 is the hdmi connector according to the pin definition of the hdmi connector (because the 19 th pin defined by the pin of the hdmi connector is a hot plug detection pin). After the power transmission controller 108 determines that the fifth electronic device 402 is the fifth master and determines that the sixth electronic device 404 is the sixth slave, the multiplexer 110 may control the third connection configuration between the first connector 102 and the second connector 106 according to the third determination result of the power transmission controller 108 and the type of the second connector 106 (i.e., the high-quality multimedia interface connector), for example, the multiplexer 110 controls USB super speed (super speed) pins SSTX1, SSRX1, SSTX2, and SSRX2 of the first connector 102 to be respectively connected to pins TMDS1, TMDS2, tmdslk, and TMDS0 of the second connector 106 (as shown in table three), that is, the signal of the USB super speed pin SSTX1 of the first connector 102 may be transmitted to the TMDS1 of the second connector 106, or vice versa. Similarly, the signal of the USB superspeed pin SSRX1 of the first connector 102 can be transmitted to the pin TMDS2 of the second connector 106, the signal of the USB superspeed pin SSTX2 of the first connector 102 can be transmitted to the pin tmdslk of the second connector 106, and the signal of the USB superspeed pin SSRX2 of the first connector 102 can be transmitted to the pin TMDS0 of the second connector 106. Therefore, when the fifth electronic device 402 is the fifth master and the sixth electronic device 404 is the sixth slave, the adaptor 100 can be used as a Type C (Type C) connector/high-definition multimedia interface connector cable (Type C-to-HDMI cable) of a universal serial bus between the fifth electronic device 402 and the sixth electronic device 404 through the third connection configuration. In addition, the fifth electronic device 402 (the fifth master) and the sixth electronic device 404 (the sixth slave) negotiate that the HDMI connector of the second connector 106 and the sixth electronic device 404 operate in an HDMI alternate mode. In addition, it should be understood by those skilled in the art that the superspeed pins SSTX1, SSRX1, SSTX2 and SSRX2 and pins TMDS0, TMDS1, TMDS2 and TMDSLK are all differential signal pair pins.

step 606: one of the electronic device and the other electronic device supplies power to the power delivery controller 108;
step 608: when the electronic device supplies power to the power transmission controller 108, the power transmission controller 108 judges that the electronic device is a master and the other electronic device is a slave, and when the other electronic device supplies power to the power transmission controller 108, the power transmission controller 108 judges that the other electronic device is another master and the electronic device is another slave;
step 610: the multiplexer 110 controls a connection configuration between the first connector 102 and the second connector according to the determination result of the power transmission controller 108 and the type of the second connector, wherein the connection configuration is used for transmitting signals between the electronic device and the other electronic device;
step 612: and (6) ending.
In step 602, take the first electronic device 202 connected to the first connector 102 and the second electronic device 204 connected to the second connector 104 as an example. In steps 604-608, as shown in fig. 2, when the second electronic device 204 is connected to the second connector 104, if the power transmission controller 108 receives the first power transmitted by the first electronic device 202 through the VBUS pin of the first connector 102, the power transmission controller 108 can determine that the first electronic device 202 is the first host according to the first power. In addition, since the second electronic device 204 does not transmit the second power to the power transmission controller 108 through the second connector 104, and the first predetermined pin (i.e. the 18 th pin of the second connector 104) of the second connector 104 is enabled, the power transmission controller 108 can determine the type of the second connector 104 as the displayport connector according to the pin definition of the displayport connector. In step 610, after the power transmission controller 108 determines that the first electronic device 202 is the first master and determines that the second electronic device 204 is the second slave, the multiplexer 110 may control a first connection configuration (as shown in table one) between the first connector 102 and the second connector 104 according to the first determination result of the power transmission controller 108 and the type of the second connector 104 (i.e., the display port connector). Therefore, when the first electronic device 202 is the first host and the second electronic device 204 is the second slave, the adapter 100 can be used as a Type C (Type C) connector/display port connector cable (Type C-to-DP cable) of a universal serial bus between the first electronic device 202 and the second electronic device 204 through the first connection configuration.
In step 602, for example, the third electronic device 302 is connected to the first connector 102 and the fourth electronic device 304 is connected to the second connector 104. In steps 604-608, as shown in fig. 3, when the fourth electronic device 304 is connected to the second connector 104, if the power transmission controller 108 receives a fourth power transmitted by the fourth electronic device 304 through a second predetermined pin (e.g., a connector power pin of the second connector 104 (i.e., the 20 th pin of the second connector 104)) of the second connector 104, the power transmission controller 108 may determine that the second connector 104 is the display port connector and determine that the fourth electronic device 304 is the fourth host according to the pin definition of the display port connector. In addition, since the third electronic device 302 does not transmit the third power to the power transmission controller 108 through the first connector 102, the power transmission controller 108 can determine that the third electronic device 302 is the third slave device accordingly. At this time, since the fourth electronic device 304 transmits the fourth power to the power transmission controller 108, the first predetermined pin of the second connector 104 (e.g., the hot plug detection pin of the second connector 104 (i.e., the 18 th pin of the second connector 104)) is turned off. In step 610, after the power transmission controller 108 determines that the third electronic device 302 is the third slave and determines that the fourth electronic device 304 is the fourth master, the multiplexer 110 may control a second connection configuration (as shown in table two) between the first connector 102 and the second connector 104 according to the second determination result of the power transmission controller 108 and the type of the second connector 104 (i.e., the display port connector). Therefore, when the third electronic device 302 is the third slave device and the fourth electronic device 304 is the fourth master device, the adapter 100 can be used as a Type C (Type C) connector cable of a displayport connector/usb between the third electronic device 302 and the fourth electronic device 304 through the second connection configuration.
In step 602, for example, the fifth electronic device 402 is connected to the first connector 102 and the sixth electronic device 404 is connected to the second connector 106. In steps 604-608, as shown in fig. 4, if the power transmission controller 108 receives the fifth power transmitted by the fifth electronic device 402 through the pin VBUS of the first connector 102, the power transmission controller 108 determines that the fifth electronic device 402 is the fifth host. In addition, since the sixth electronic device 404 does not transmit the sixth power to the power transmission controller 108 through the second connector 106, and a third predetermined pin (i.e. the 19 th pin of the second connector 106) in the second connector 106 is enabled, the power transmission controller 108 can determine that the sixth electronic device 404 is the sixth slave device accordingly, and can determine that the second connector 106 is the hdmi connector according to the pin definition of the hdmi connector. At this time, since the sixth electronic device 404 is connected to the second connector 106, a third predetermined pin of the second connector 106 (e.g., a hot plug detect pin of the second connector 106 (i.e., the 19 th pin of the second connector 106)) is enabled. In step 610, after the power transmission controller 108 determines that the fifth electronic device 402 is the fifth master and determines that the sixth electronic device 404 is the sixth slave, the multiplexer 110 may control a third connection configuration between the first connector 102 and the second connector 106 according to the third determination result of the power transmission controller 108 and the type of the second connector 106 (i.e., the hdmi connector) (as shown in table three). Therefore, when the fifth electronic device 402 is the fifth master and the sixth electronic device 404 is the sixth slave, the adaptor 100 can be used as a Type C (Type C) connector/hdmi connector cable of the usb between the fifth electronic device 402 and the sixth electronic device 404 through the third connection configuration.
In step 602, for example, the seventh electronic device 502 is connected to the first connector 102 and the eighth electronic device 504 is connected to the second connector 106. In steps 604-608, if the power transmission controller 108 receives an eighth power from the eighth electronic device 504 via a fourth predetermined pin of the second connector 106 (e.g., the power pin of the second connector 106 (i.e., the 18 th pin of the second connector 106)), the power transmission controller 108 determines that the eighth electronic device 504 is the eighth host and determines that the second connector 106 is the hdmi connector according to the pin definition of the hdmi connector. In addition, since the seventh electronic device 502 does not transmit the seventh power to the power transmission controller 108 through the first connector 102, the power transmission controller 108 can determine that the seventh electronic device 502 is the seventh slave device accordingly. In step 610, after the power transmission controller 108 determines that the seventh electronic device 502 is the seventh slave and determines that the eighth electronic device 504 is the eighth master, the multiplexer 110 may control a fourth connection configuration between the first connector 102 and the second connector 106 (as shown in table four) according to a fourth determination result of the power transmission controller 108 and the type of the second connector 106 (i.e., the hdmi connector). Therefore, when the seventh electronic device 502 is the seventh slave device and the eighth electronic device 504 is the eighth master device, the adaptor 100 can be used as a Type C (Type C) connector cable of the hdmi connector/usb between the seventh electronic device 502 and the eighth electronic device 504 through the fourth connection configuration.
