That is, when the plug connector 20 is installed in the vehicle diagnostic device, the plug connector 10 is disposed on the connection line of the electronic device. Conversely, when the plug connector 10 is disposed in the vehicle diagnostic device, the plug connector 20 is disposed on the connection line of the electronic device. The specifications of the above connecting lines are USB (Universal Serial Bus) connection lines, Mini-USB, Micro-USB, RS serial wiring (such as RS-232, RS-485, RS-468, etc.).

The plug connector 10 is provided with a device under test 11, and the device under test 11 is disposed on the plug connector 10. When the plug connector 10 is inserted into the socket 20, the device under test 11 is adjacent to the socket 20.

The connection interface 21 is used for plugging the connector 10, the socket control unit 22 is connected to the connection interface 21 and the sensing unit 23. The sensing unit 23 is disposed on the socket 20, and the plug connector 10 is inserted into the socket. At 20 o'clock, the sensing unit 23 will be adjacent to the device under test 11.

The above-mentioned device under test 11 is used to provide this physical signal. When the plug connector 10 is inserted into the socket 20, the socket control unit 22 drives the sensing unit 23, and the sensing unit 23 continues to sense whether or not the physical signal is sensed. This socket control The unit 22 performs a line setting behavior between the connection interface 21 and the plug connector 10 according to the sensing result of the sensing unit 23.

When the sensing unit 23 acquires the physical signal, a sensing value (eg, a high potential signal) is sent to the outlet control unit 22. When the socket control unit 22 obtains the sensed value, it is determined that the device under test 11 exists. The line setting behavior performed by the socket control unit 22 includes forming a path for the data transmission path between the connection interface 21 and the plug connector 10, so that the vehicle diagnostic device and the electronic device can perform data transmission and interaction.

Conversely, the plug connector 10 is not provided with the above-described device under test 11, and the sensing unit 23 does not acquire a physical signal. The sensing unit 23 does not send the sensed value or sends another sensed value (eg, a low potential signal) to the outlet control unit 22. At this time, the line setting behavior performed by the socket control unit 22 includes: causing the data transmission path between the plug connectors 10 of the connection interface 21 to form an open circuit, and the vehicle diagnostic device and the electronic device cannot perform any data transmission and interaction.

In some embodiments, the docking station 20 includes a power supply module 24 that is connected to a power line 12 of the plug connector 10 through the connection interface 21 . When the sensing unit 23 acquires the physical signal, a sensing value (eg, a high potential signal) is sent to the outlet control unit 22. When the socket control unit 22 obtains the sensed value, it is determined that the device under test 11 exists. The line setting behavior performed by the outlet control unit 22 includes causing the power supply module 24 to provide power transmission to the power line 12. When the docking station 20 is installed in the vehicle diagnostic device, the plug connector 20 can be powered by the power supply module 24 to the connected electronic device through the plug connector 10 connected to the docking station 20. The power source of the power supply module 24 may be a battery that it has, an external power supply device connected to the power supply module 24, or a supply power of the vehicle diagnostic device. Alternatively, when the docking station 20 is disposed on the electronic device connected to the vehicle diagnostic device, the plug connector 20 can be powered by the power supply module 24 to the connected vehicle diagnostic device through the plug connector 10 connected to the docking station 20. The power source of the power supply module 24 may be a battery that it has, an external power supply device connected to the power supply module 24, or a power supply of the electronic device.

Conversely, the plug connector 10 is not provided with the above-described device under test 11, and the sensing unit 23 does not acquire a physical signal. The sensing unit 23 does not send the sensed value or sends another sensed value (eg, a low potential signal) to the outlet control unit 22. At this time, the line setting behavior performed by the socket control unit 22 includes: stopping the power supply module 24, and the power supply module 24 no longer supplies any power to the power line 12. A device connected at either end of the cable will no longer receive power from the power module 24.

Further, regardless of whether the power supply module 24 is powered, the outlet control unit 22 still forms a path for the data transmission path between the connection interface 21 and the plug connector 10.

Please refer to the hardware structure diagram of the second vehicle diagnostic interface plug structure shown in FIG. 3 and the block diagram of the second vehicle diagnostic interface plug structure shown in FIG. 4 .

When the plug connector 10 is inserted into the socket 20, the socket control unit 22 sends a setting data to the plug control unit 13 to communicate with the plug control unit 13 to set the connection interface 21 regardless of whether the power supply module 24 is powered. A data transmission path is formed with the plug connector 10 to form a path.

Please also refer to FIG. 3 and FIG. 4 . In some embodiments, when the sensing unit 23 obtains the physical signal, a sensing value (eg, a high potential signal) is sent to the outlet control unit 22 . When the socket control unit 22 obtains the sensed value, it is determined that the device under test 11 exists. The line setting behavior performed by the socket control unit 22 includes: transmitting a setting data to the plug control unit 13, and setting a data transmission path forming path between the connection interface 21 and the plug connector 10 by interacting with the plug control unit 13 The vehicle diagnostic device and the electronic device can perform data transmission and interaction.

Conversely, the plug connector 10 is not provided with the above-described device under test 11, and the sensing unit 23 does not acquire a physical signal. The sensing unit 23 does not send the sensed value or sends another sensed value (eg, a low potential signal) to the outlet control unit 22. At this time, the line setting by the outlet control unit 22 The behavior includes: the configuration data is not sent, and the plug control unit 13 cannot obtain the setting data, so that the data transmission path between the plug connector 10 of the connection interface 21 forms an open circuit, and the vehicle diagnostic device and the electronic device cannot perform any data transmission and interaction.

However, the above-mentioned data transmission path and disconnection, and the line setting behavior of the power supply module 24 for power supply, can be designed and operated separately, or integrated and designed to operate in the vehicle diagnostic interface plug structure.
