Abstract
The utility model relates to the field of connectors and particularly relates to a board-to-board connector, which comprises a base, an insulating body, a plurality of first terminals and a plurality of second terminals. The second nickel layer parts of the second terminals pass through the through holes of the insulating body, so that the holding force between the second terminals and the insulating body is effectively improved. Due to the adoption of the first nickel layer parts of the first terminals and the second nickel layer parts of the second terminals, the occurrence of poor phenomena during the welding process of the board-to-board connector, such as the tin-lying phenomenon and the like, can be effectively relieved, so that the performances of products are improved. The extra labor and material cost caused by the rework for the defected production can be lowered. Each first terminal is of a doubly corrugated structure formed by a mounting part and an elastic part, so that the spring characteristics of contact parts are ensured. As a result, the holding force between the second terminals and the first terminals is increased effectively. Meanwhile, the anti-falling resistance and the distortion resistance performance are improved.
