For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0062] like Figure 1 The data cable structure shown includes at least three ports, which are connected to each other.

[0063] The port types of each of the three ports can be the same or different, and the port types include, but are not limited to, USB-Type A, USB-Type B, USB-Type C, Lightning, Micro-USB and other interfaces.

[0064] like Figure 2The data cable structure shown includes a first port comprising a first power line Vbus1, a first switch S1, a second switch S2, and a first power converter 201.

[0073] Specifically, when the microprocessor chip 310 determines, based on the first configuration information, the second configuration information, and the third configuration information, that the first port is connected to the adapter and the second and third ports are respectively connected to the terminal device, the microprocessor chip 310 outputs a first signal through the switch control interface 315; when the microprocessor chip 310 determines, the second port is connected to the adapter and the first and third ports are respectively connected to the terminal device, the microprocessor chip 310 outputs a second signal through the switch control interface 315; when the microprocessor chip 310 determines, the third port is connected to the adapter and the first and second ports are respectively connected to the terminal device, the microprocessor chip 310 outputs a third signal through the switch control interface 315.

The microprocessor chip 310 identifies the port connected to the adapter according to the configuration information of the first configuration interface 312, the second configuration interface 313, and the third configuration interface 314, and sends the charging request to the adapter through the corresponding signal interface. Taking the first port connected to the adapter and the second and third ports connected to the terminal device as an example, the microprocessor chip 310 receives the charging request of the terminal device through the second signal interface 317 and the third signal interface 318 respectively, and sends the charging request to the first port through the first signal interface 316.
