An electrical connector includes a pedestal terminal which has a base board, two fastening boards extending upward from two sides of the base board, and two elastic boards extending upward from two free ends of the fastening boards and inclined gradually away from each other in process of extending upward, and a connecting terminal having two elastic arms and a bent portion connecting the elastic arms together to make the connecting terminal show a substantial inverted-V shape. Two free ends of the elastic boards are bent inward to form two restraining portions. Two free ends of the elastic arms are arched outward to form two interfering portions. The connecting terminal is movably engaged with the pedestal terminal with the elastic arms restrained between the restraining portions, the interfering portions abutting against insides of the corresponding elastic boards and the bent portion projecting upward beyond the pedestal terminal.
