a plurality of terminals, a ground terminal and a signal terminal which are adjacently arranged on the left and right, and are respectively and correspondingly accommodated in the accommodating holes, each ground terminal comprises a main body part positioned in the accommodating hole, an upper elastic arm which is bent upwards and extends from the main body part, and a lower elastic arm which is bent downwards and extends from the main body part, an upper groove penetrates through the upper elastic arm, so that the upper elastic arm is divided into two upper parts positioned on the left and right sides of the upper groove by the upper groove, each upper part comprises a first section which is bent upwards and extends from the main body part, and a second section which is outward extended and extends forwards from the first section, the distance between the two second sections is larger than the distance between the two first sections, the two first sections are positioned between the two corresponding side walls along the projection of the vertical direction, the two second sections extend outwards to exceed the corresponding side walls, and extend upwards from the left and right sides of the main body part to form two material connecting parts, the connecting part is used for connecting the material belt, the two first sections are positioned between the two connecting parts, the tail end of the connecting part which is connected with the two second sections is a free end, and the connecting part backwards and upwards extends to form an upper abutting part which is used for upwards abutting against the abutting element, and the upper abutting part is positioned right above the upper groove.
10. The electrical connector of claim 9, wherein the signal terminal has a base portion, an upper extending portion bent upward from the base portion, an upper contact portion bent upward from the upper extending portion and extending forward to abut the mating member upward, a distance between left and right sides of the upper extending portion is greater than a distance between left and right sides of the upper contact portion, and the upper contact portion overlaps the second section in a left-right direction when projected in the up-down direction.
