Further, the second bending portion 12 penetrates through the board surface to form a first through groove 121, the first through groove 121 extends from the intersection of the first bending portion 11 and the second bending portion 12 to the intersection of the second bending portion 12 and the third bending portion 13, the fourth bending portion 14 penetrates through the surface to form two parallel second through grooves 141, and each of the second through grooves 141 extends from the intersection of the third bending portion 13 and the fourth bending portion 14 to the intersection of the fourth bending portion 14 and the fifth bending portion 15, so that the socket terminal 100 with firm plugging force dissipates heat, the elastic force of the first bending portion 11, the second bending portion 12, the third bending portion 13, the fourth bending portion 14 and the fifth bending portion 15 is also increased, and the base 1 is convenient to disassemble and assemble the plugging panel. Further, the plate surface of the fifth bending portion 15 protrudes outward to form a boss 151, and the end surface thereof is bent away from the fourth bending portion 14 to form two clamping portions 152, the boss 151 and the clamping portions 152 make the base 1 better elastically cooperate with the socket panel by virtue of the elastic force of the base, so that when the assembly is reduced, the internal stress generated by rigid extrusion of the base 1 is reduced, and the durability of the socket terminal 100 with firm plugging force is improved.
