Connector and method for charging control with the connector

A method for power-supplying control with a connector for coupling a first electronic device and a second electronic device with a power source to enable the power source to provide a current to the first electronic device and the second electronic device, wherein the first electronic device is able to communicatively be connected to the second electronic device via the connector and supply power to the second electronic device, and the connector comprises:

• a first connector component configured to be coupled with the first electronic device;
• a second connector component configured to be coupled with the second electronic device;
• a third connector component configured to be coupled with the power source;
• a power line configured to be coupled with the first connector component, the second connector component, and the third connector component;
• a first data line configured to operatively couple any two of the first connector component, the second connector component, and the third connector component via a signal switching circuit;
• and
• the signal switching circuit is configured to:
• detect whether the third connector component is coupled with the power source;
• control the first connector component and the second connector component to be coupled via the first data line when it is not detected that the third connector component is coupled with the power source;
• and
• when it is detected that the third connector component is coupled with the power source:
• control the first connector component and the third connector component to be coupled via the first data line, to send a power source connection message to the first electronic device via the first data line;
• or
• control the second connector component and the third connector component to be coupled via the first data line, to send a power source connection message to the second electronic device via the first data line,
• wherein, the power source connection message is configured to indicate that the third connector component is coupled with the power source;
• wherein the method comprises:
• detecting whether the third connector component is coupled with the power source;
• controlling the first connector component and the second connector component to be coupled via the first data line when it is not detected that the third connector component is coupled with the power source;
• and
• when it is detected that the third connector component is coupled with the power source:
• controlling the first connector component and the third connector component to be coupled via the first data line, to send a power source connection message to the first electronic device via the first data line;
• or
• controlling the second connector component and the third connector component to be coupled via the first data line, to send a power source connection message to the second electronic device via the first data line,
• wherein, the power source connection message is configured to indicate that the third connector component is coupled with the power source.
