Abstract
The utility model discloses an electric connector terminal used for electrically connecting a chip module group and a printed circuit board, which comprises a fixing part, a welded part downward extending out from one end of the fixing part and a base part upward extending out from the other end of the fixing part. Both sides of the base part respectively extend out a first supporting part and a second supporting part. The tail-end upward extending out from the first supporting part is provided with a first elastic arm of a first contacting part. The tail-end upward extending out from the second supporting part is provided with a second elastic arm of a second contacting part. The first elastic arm and the second elastic arm are crosswise arranged. Arranging the two elastic arms can increase elasticity and the mechanical property of the whole electric connector terminal. The first contacting part and the second contacting part are arranged by extending toward each other, and at the same time are electrically communicated with the same conducting strip arranged on the chip module group, so that the resistance generated by the two elastic arms to the chip module group is automatically counteracted and the frictional resistance received by the whole chip module group is reduced.
