Patent ID: 7537488

Claim:
A plug connector comprising: a standard terminal provided on a first insulator surface in compliance with a standard of terminal configuration; an additional terminal provided in association with a second insulator surface, and provided not in compliance with said standard, said second insulator surface being not in plane with said first insulator surface, said second insulator surface being not parallel with said first insulator surface; and a metal shield at least partially covering said standard terminal and said additional terminal, wherein said first insulator surface is a surface of a protrusion, said protrusion being formed on an inner surface of said metal shield and extending in a plug direction of said connector, wherein said second insulator surface is not parallel with said plug direction and is a surface of an insulation body formed on said protrusion, said additional terminal having a contact point thereof provided at said second insulator surface, said contact point being positioned to provide electrical connection with a corresponding contact point of a terminal of a receptacle connector when said plug and said receptacle connectors plugged with each other, and said body extending in said plug direction for a length smaller than a length of said protrusion along said plug direction.
