The plurality of side walls protrude upward along the periphery of the substrate, and the nesting portion protrudes upward from the middle portion of the base plate, and the series of side walls and the nesting portion enclose a receiving space. A plurality of mounting holes are formed in the nesting portion relative to the first terminal slot. The first terminal has a first base portion, a first solder tail portion, a holding portion and a first elastic contact portion. The first solder tail portion extends from the first base portion in an extending direction of the first base portion toward the socket in the first terminal slot. The main body is electrically connected to the circuit board, and the first base portion extends upwardly from the inner side of the first solder tail portion to the holding portion, and the other end of the first base portion is bent substantially vertically upward to extend into the first elastic contact portion, and is received in the nesting portion. In the mounting hole, the top end of the first elastic contact portion has a contact head that protrudes into the receiving space. However, the above structural design makes that in the process of soldering the first terminal of the socket and the circuit board by soldering, due to uneven distribution of tin, some first solder tails may be distributed with more tin at the first solder tail. At the time, the excess of the 5 M308518 base and the tin remaining to the terminal may cause poor contact by the first solder tail through the contact area of the first contact. [New content] The present invention provides a board-to-board connector for the above-mentioned deficiencies, comprising: an insulative body having a bottom plate, the bottom plate of which protrudes upwardly from opposite sides, opposite to the first side wall and the opposite ends of the bottom plate Projecting upwardly—for the second side wall, the bottom plate protrudes upward from the middle portion—the nesting portion, and the nesting portion forms a receiving cavity with the first and second side walls, and the opposite sides of the insulating body respectively Each of the terminal slots includes a first receiving slot formed in the bottom plate, and the first receiving slot extends laterally inwardly into the outer side of the bottom of the nesting portion, and extends outwardly through the first side wall to communicate with the outside.
