A connector comprises a pair of terminals for clamping and electrically connecting to a first conductive member. A first terminal includes a plurality of first elastic arms arranged in a row, with each first elastic arm having a first contact and a third contact formed thereon. The second terminal is laminated on an outer side of the first terminal and includes a plurality of second elastic arms arranged in a row. Each second elastic arm includes a second contact formed thereon. Each second contact protrudes to an inner side of the first elastic arms from a gap between two adjacent first elastic arms. The plurality of second elastic arms respectively abut against the outer sides of the plurality of first elastic arms. The first contact, the second contact and the third contact are adapted to be in electrical contact with the inserted first conductive member simultaneously.
