  • Publication number: 20210075140
    Abstract: An electrical terminal includes a base, a first elastic arm and a second elastic arm formed side by side by extending upwardly from an upper end of the base, and a protruding portion. The first elastic arm has a mating portion, and the second elastic arm has a contact portion. The protruding portion protrudes and extends from a first side of the first elastic arm, and the first side of the first elastic arm is adjacent to the second elastic arm. A lower surface of the protruding portion has a contact surface overlapping with the contact portion in a vertical direction, such that the contact portion upwardly abuts the contact surface. When the chip module presses downwardly on the electrical terminal, the contact portion can move on the contact surface, such that the chip module does not need to press downwardly on the contact portion with a relatively large pressure.
