Abstract: A terminal structure comprises a mounting portion, an inserting portion, and a contact portion. The mounting portion has two sides each having a positioning tooth; and the inserting portion is connected to a lower end the mounting portion. The contact portion is installed above the mounting portion, and a fork shape first arm and a fork shape second arm extends from an upper end of the mounting portion. The second arm has a connecting portion extending from a lower end at one side of the first arm for being formed as a suspending arm with a free upper end and slightly tilt to a front side or outer side of the terminal. The contact portion is connected to an upper end of the second arm. Therefore, a terminal is formed, which can achieve a preferred electric and mechanic connection with the electronic elements of a pin grid array (PGA) chip.
