Connector module and electronic device using the same

An electronic device, comprising:

• a host;
• a power adaptor;
• a first connector selectively disposed at one of the host and the power adaptor, wherein the first connector includes a plug hole;
• a first electrode disposed in the plug hole;
• a second connector selectively disposed at the other one of the host and the power adaptor, wherein the second connector includes a connecting portion, and a projecting area of the connecting portion is larger than that of the plug hole;
• a second electrode disposed at the connecting portion;
• and
• a light emitting unit disposed at the second connector, and when the first electrode is electrically connected to the second electrode, the light emitting unit turns on;
• wherein when the connecting portion of the second connector is disposed in the first connector, the first electrode contacts the second electrode, and an inner wall of the plug hole restrains the connecting portion from detaching from the plug hole.
