Referring to fig. 4 and 5, a schematic structural diagram of a power terminal and a schematic structural diagram of a metal member of the socket of the present utility model are shown. The utility model relates to a board-to-board socket electric connector, which mainly comprises an insulating base 20, a plurality of socket terminals 22, a socket power terminal 24 and a metal piece 26, wherein the insulating base 20 comprises a pair of base side walls 200 and a pair of base end walls 202, each base side wall 200 and each base end wall 202 enclose an inserting space 204, a guide post 206 is arranged in the inserting space 204, each socket terminal 22 is respectively arranged at two sides of each base side wall 200 and the guide post 206, the socket power terminal 24 defines a power welding part 240, a fixing part 241, an elastic contact part 242 and a coating structure 243, the power welding part 240 is arranged at the bottom of the base end wall 202, the fixing part 241 extends from the power welding part 240 and is buried in the insulating base 10, each elastic contact part 242 extends from two sides of the fixing part 241 towards the base side wall 200, and the coating structure 243 extends from one side of the fixing part 241 towards the guide post 206 and is used for coating one end of the guide post 206.

The metal piece 26 defines a first welding portion 260, a second welding portion 261, an extension portion 262 and a guiding portion 263, the first welding portion 260 is located at the outer side of the base end wall 202, the second welding portion 261 is located at the outer side of the base side wall 200, the extension portion 262 extends from the first welding portion 260 and the second welding portion 261 and is disposed on the top surfaces of the base end wall 202 and the base side wall 200, and the guiding portion 263 is bent towards the inserting space 204 from the extension portion 262 located on the base end wall 202 and the base side wall 200, wherein the two first welding pins 2600 on the first welding portion 260 and the two second welding pins 2610 on the second welding portion 261 are both welded on the circuit board.

The first welding portion 260 has a first barb structure 2602 formed on at least one side, the first barb structure 2602 interferes with the insulating base 10 structurally, the second welding portion 261 has a second barb structure 2612 formed on at least one side, the second barb structure 2612 interferes with the insulating base 10 structurally, and when the metal piece 26 is assembled on the base end walls 202 at two ends of the insulating base 10 through the above structure, the structural fastening effect on the insulating base 10 can be achieved through the first barb structure 2602 and the second barb structure 2612, so as to avoid possible detachment or loosening of the metal piece 26.
