[0026] See also Figure 2 , a resilient terminal 3, a power terminal 4, and a pair of signal terminals 5 are respectively embedded in the socket connector 1 and the plug connector 2. The resilient terminal 3 of the socket connector 1 is electrically connected to the power terminal 4 of the plug connector 2, the power terminal 4 of the socket connector 1 is electrically connected to the resilient terminal 3 of the plug connector 2, and the signal terminal 5 of the socket connector 1 is electrically connected to the signal terminal 5 of the plug connector 2.

[0027] Please see again Figures 3 to 5 ,like Figure 3 As shown, the elastic terminal 3 is formed by stamping and bending a metal plate, and the elastic terminal 3 includes a rectangular base 31 and an elastic structure 32 extending forward from the front end of the base 31. The base 31 includes a top plate 311, two side plates 312 extending vertically downward from the two side edges of the top plate 311, and a bottom plate 313 arranged at the bottom edges of the two side plates 312. The elastic structure 32 includes an upper elastic arm 321 extending forward from the front edge of the top plate 311, a lower elastic arm 322 extending forward from the front edge of the bottom plate 313, and four side elastic arms 323 extending forward from the front edges of the two side plates 312.

Furthermore, the front ends of the upper elastic arm 321 , the lower elastic arm 322 and the side elastic arm 323 are respectively bent inward to form a contact portion 324 , so the elastic terminal 3 in this embodiment is provided with six contact portions 324 in total.

[0028] And as Figure 5As shown, the power terminal 4 is provided with a connecting portion 41, a stopper portion 42 and at least one barb 43. The connecting portion 41 is provided in a rectangular body and is placed at the front end of the power terminal 4, and the connecting portion 41 extends into the interior of the elastic terminal 3 to be electrically connected with the contact portion 324. The stopper portion 42 and the barb 43 are both formed by protruding outward from the outer surface of the power terminal 4, and the barb 43 is located at the front end of the stopper portion 42.

[0029] Therefore, when the socket connector 1 is docked with the plug connector 2, the connecting portion 41 and the contact portion 324 abut against each other, causing the elastic structure 32 to expand and deform along the outer surface of the power terminal 4, thereby forming a larger contact area with the power terminal 4 to reduce the impedance during current transmission and avoid overheating problems, thereby improving the signal transmission stability of the electrical connector group 100.

[0030] See also Figure 6 and Figure 7 The socket connector 1 comprises a socket body 11, which is a rectangular shell made of insulating material.
