Connector with signal detection device

A connecting combination for providing a detecting signal to an electronic device, comprising:

• a socket positioned in said electronic device and comprising a central protruding conductor and an outer insulating portion, wherein said outer insulating portion comprises a first contacting flexible piece and a second contacting flexible piece;
• a connector plugged in said socket and comprising a first conducting portion for contacting with said central protruding conductor, a second conducting portion for contacting with said first contacting portion, and a third conducting portion for contacting with said second contacting portion, wherein said third conducting portion outputs a detecting signal for being recognized when said connector is plugged in said socket of said electronic device and said third conducting portion is contacted with said second contacting flexible piece, and said connector stands on said detecting signal to decide whether power is outputted to said electronic device or not.

A connector with a signal detection device for plugging in a corresponding socket of an electronic device, wherein said socket comprises plural contacting conducting portions, comprising:

• plural conducting portions having a corresponding relationship with said plural contacting conducting portions of said socket, wherein said plural conducting portions comprises a first number of conducting portion and a second number of conducting portion, when said connector is plugged in said socket of said electronic device, said first number of conducting portion outputs a first number of detecting signal and contacts with a first number of contacting conductor, and said connector stands on said detecting signal to decide whether power is outputted to said electronic device or not.

A connector with a signal detection device for plugging in a corresponding socket of an electronic device, wherein said connector comprises plural conducting portions and said socket comprises a recognizing portion, characterized in that:

• when said connector is connected to said socket and one of said plural conducting portions is contacted with said recognizing portion, said one of said plural conducting portion outputs a detecting signal and, said connector stands on said detecting signal to decide whether a power is outputted to said electronic device or not for completing an electrical conduction.
