The grounding terminal 121 has a second electrical connection section 1211 and a second fixing section 1212 connected to each other in a V shape. The second fixing section 1212 is plug-in type and has an insertion section 12121 extending longitudinally toward the second electrical connection section 1211.

[0042] like Figure 1 and Figure 7As shown, the signal elastic portion 33 includes a first signal side edge 331 and a second signal side edge 332 opposite to each other. The first signal side edge 331 is located behind the second signal side edge 332, and the first signal side edge 331 and the second signal side edge 332 are positions of the signal elastic portion 33 corresponding to two opposite signal cutting edges of the signal terminal 3. In other embodiments, the first signal side edge 331 and the second signal side edge 332 are positions of the signal elastic portion 33 corresponding to two opposite signal board edges of the signal terminal 3.

[0043] like Figure 1 and Figure 7 As shown, the grounding terminal 4 includes two opposite grounding plate edges (unnumbered) and two opposite grounding cutting edges (unnumbered), and the grounding plate edges and the grounding cutting edges are connected. The distance between the two opposite grounding plate edges is defined as the thickness of the grounding terminal 4, and the distance between the two opposite grounding cutting edges is defined as the width of the grounding terminal 4. The grounding plate edge of the grounding terminal 4 is directly opposite to the signal plate edge of the signal terminal 3 in the left-right direction. When viewed from the left-right direction, the projection of the entire signal terminal 3 in the front-to-back direction is located within the projection of the entire grounding terminal 4. Specifically, in this embodiment, not only when viewed from the left-right direction, the entire grounding terminal 4 in the front-to-back direction can shield the entire signal terminal 3, but also the distance between the two grounding cutting edges is required to be greater than the distance between the two signal cutting edges, and does not include the case where the distance between the two grounding cutting edges is equal to the distance between the two signal cutting edges. In other embodiments, the grounding plate edge of the grounding terminal 4 is directly opposite to the signal cutting edge of the signal terminal 3 in the left-to-right direction. Not only when viewed from the left and right directions, the entire ground terminal 4 can shield the entire signal terminal 3 along the front and back directions, but also the distance between the two ground cutting edges must be greater than the distance between the two signal board edges, and does not include the situation where the distance between the two ground cutting edges is equal to the distance between the two signal board edges.

[0044] like Figure 2 As shown, the grounding terminal 4 includes a grounding body portion 41, a grounding contact portion 42, a grounding elastic portion 43 connecting the grounding body portion 41 and the grounding contact portion 42, and a grounding conductive portion 44 connected to one end of the grounding body portion 41 away from the grounding elastic portion 43. The grounding terminal 4 of the first terminal row also includes a shielding portion 45 bent and extended from the grounding body portion 41. The grounding body portion 41 of the grounding terminal 4 of the first terminal row is fixed forward to the insulating body 1, the grounding contact portion 42 protrudes from the grounding receiving groove 142 to the card insertion groove 13, and is used to abut the first electronic component 200, and the grounding conductive portion 44 is used to abut the second electronic component 300.

[0045] like Figure 2 and Figure 8As shown, the grounding main body 41 includes a grounding extension portion 411 extending downward from the grounding elastic portion 43 and a grounding fixing portion 412 extending forward from the grounding extension portion 411. The grounding extension portion 411 includes a riveted portion 4111 connected to the rear end of the grounding fixing portion 412 and a connecting portion 4112 extending upward from the riveted portion 4111. The shielding portion 45 is bent and extended forward from the rear end of the connecting portion 4112, the first clamping portion 212 clamps the shielding portion 45 and the connecting portion 4112 of the same grounding terminal 4, and the second clamping portion 222 clamps the riveted portion 4111. The grounding fixing portion 412 is received forward in the grounding fixing groove 1422, and then assembled and fixed to the insulating body 1.

[0046] like Figure 3 to Figure 4 As shown, the grounding elastic portion 43 of the grounding terminal 4 of the first terminal row includes a first section 431 extending upward and forward obliquely from the riveting portion 4111, a second section 432 extending forward by bending from the first section 431, and a notch 433 located only in the first section 431. In other embodiments, the notch 433 may extend from the first section 431 to the second section 432. The notch 433 passes through the first section 431 in the left-right direction, corresponds to a part of the signal elastic portion 33 in the left-right direction, and the shielding portion 45 shields the notch 433 in the left-right direction, and the projection of the signal elastic portion 33 is located within the common projection of the shielding portion 45 and the grounding elastic portion 43. The shielding portion 45 and the first section 431 are both located outside the grounding accommodation groove 1421. In this embodiment, the shielding portion 45 is located on the left side of the first section 431, and in other embodiments, the shielding portion 45 may be located on the right side of the first section 431. The riveting portion 4111 is connected to the first section 431, and the connecting portion 4112 is located behind the first section 431 and there is a gap 434 between the connecting portion 4112 and the first section 431, and the gap 434 is connected to the notch 433. Without changing the terminal size, the length of the grounding elastic portion 43 can be extended, which is beneficial to reduce the positive force and the yield. The second section 432 is accommodated in the grounding receiving groove 1421 from the back to the front, and the grounding contact portion 42 protrudes downward from the second section 432 to the card slot 13 and abuts against the first electronic component 200 downward.

[0047] like Figure 5 and Figure 7As shown, the grounding elastic portion 43 of the first terminal row also includes a first grounding side edge 435 and a second grounding side edge 436. The first grounding side edge 435 is located behind the second grounding side edge 436, and the first grounding side edge 435 and the second grounding side edge 436 are two opposite grounding cut edges of the grounding terminal 4 corresponding to the position of the grounding elastic portion 43. When viewed from the left and right direction, the distance D1 from the first grounding side edge 435 to the second grounding side edge 436 is greater than the distance D2 from the first signal side edge 331 to the second signal side edge 332. In this embodiment, the notch 433 is recessed from the first grounding side edge 435 of the first section 431 to the second grounding side edge 436 of the first section 431, and the shielding portion 45 is bent and extended along the first grounding side edge 435 toward the second grounding side edge 436; in other embodiments, the notch 433 is recessed from the second grounding side edge 436 of the first section 431 to the first grounding side edge 435 of the first section 431; and in some other embodiments, the notch 433 is located between the first grounding side edge 435 and the second grounding side edge 436.

[0048] like Figures 5 and 6As shown, the length D3 of the notch 433 along the extension direction of the first section 431 is greater than the distance D1 between the first grounding side 435 and the second grounding side 436, which is conducive to reducing the normal force and yield. The notch 433 includes an inner edge 4331, and the inner edge 4331 connects the first grounding side 435 and the connecting portion 4112. In this embodiment, the shortest distance D4 between the second grounding side 436 and the inner edge 4331 is less than half of the distance D1 between the first grounding side 435 connecting one end of the inner edge 4331 and the second grounding side 436; in other embodiments, the shortest distance between the second grounding side 436 and the inner edge 4331 is equal to half of the distance between the first grounding side 435 connecting one end of the inner edge 4331 and the second grounding side 436; the above two embodiments are conducive to reducing the normal force of the grounding elastic portion 43. The distance between the first grounding side edge 435 connected to one end of the inner edge 4331 and the second grounding side edge 436 is the width of the grounding elastic portion 43 before the recessed notch 433, and the shortest distance between the second grounding side edge 436 and the inner edge 4331 is the minimum width of the grounding elastic portion 43 after the recessed notch 433. The shielding portion 45 includes a third grounding side edge 451 close to the first grounding side edge 435 and a fourth grounding side edge 452 close to the second grounding side edge 436. The third grounding side edge 451 and the fourth grounding side edge 452 are opposite to each other and the third grounding side edge 451 is located behind the fourth grounding side edge 452. In this embodiment, when viewed from the left and right directions, the distance D5 between the third grounding side edge 451 and the second grounding side edge 436 is greater than the distance D1 between the first grounding side edge 435 and the second grounding side edge 436; in other embodiments, when viewed from the left and right directions, the distance between the third grounding side edge 451 and the second grounding side edge 436 is equal to the distance between the first grounding side edge 435 and the second grounding side edge 436; both of the above two embodiments can ensure a good shielding effect at the notch 433 of the grounding terminal 4. When viewed from the left and right directions, the fourth grounding side edge 452 is within the projection of the grounding elastic portion 43, ensuring a good shielding effect at the notch 433 of the grounding terminal 4.

[0049] like Fig. 9As shown, the insulating body 1 is further provided with a stop surface 15 located right in front of the signal elastic part 33, and an extension surface 16 extending from the stop surface 15 to the ground terminal 4 in the left-right direction. The stop surface 15 and the extension surface 16 are located in the same plane. The extension surface 16 is located between the signal elastic part 33 and the shielding part 45 in the front-to-back direction, and the extension surface 16 is located in front of the shielding part 45. The insulating body 1 is further provided with a clearance space 17, and a guide inclined surface 18 connecting the clearance space 17 and the extension surface 16. The clearance space 17 is located right in front of the extension surface 16 and makes way for the front of the shielding part 45. In the front-to-back direction, the extension surface 16 is located between the signal elastic part 33 and the shielding part 45, and the extension surface 16 is located in front of the shielding part 45. In the left-to-right direction, the extension surface 16 makes way for the shielding part 45, and the clearance space 17 is located in front of the extension surface 16 and makes way for the front of the shielding part 45.

[0050] In summary, the electrical connector 100 of the present invention has the following beneficial effects:

[0051] 1. When viewed along the direction in which the plurality of signal terminals 3 and the plurality of grounding terminals 4 are arranged, the distance D1 between the first grounding side edge 435 and the second grounding side edge 436 is greater than the distance D2 between the first signal side edge and the second signal side edge, which is beneficial to ensuring the shielding effect of the grounding terminal 4. However, it will cause the positive force of the grounding elastic portion 43 to be greater than the positive force of the signal elastic portion 33. In order to reduce the positive force of the grounding elastic portion 43, a notch 433 is recessed in the grounding elastic portion 43 and is through the direction in which the plurality of signal terminals 3 and the plurality of grounding terminals 4 are arranged. However, since the notch 433 corresponds to a part of the signal elastic portion 33, the signal emitted by the signal elastic portion 33 is easily passed through the notch 433, thereby affecting the shielding effect of the grounding terminal 4. The shielding portion 45 is bent and extended from the grounding main body portion 41. The shielding portion 45 shields the notch 433. The projection of the signal elastic portion 33 is located within the common projection of the shielding portion 45 and the grounding elastic portion 43. The signal emitted by the signal elastic portion 33 can be effectively shielded, signal interference is reduced, and the shielding effect of the grounding terminal 4 is ensured.

[0052] 2. Since the notch 433 is recessed from the first grounding side edge 435 to the second grounding side edge 436, compared with the shielding portion 45 bending and extending along the second grounding side edge 436 toward the first grounding side edge 435, the shielding portion 45 bending and extending along the first grounding side edge 435 toward the second grounding side edge 436 can save materials to the maximum extent while ensuring the shielding effect.

[0053] 3. Since the first section 431 is connected to the grounding main body 41, and the grounding main body 41 is fixed to the insulating body 1, the stress concentration is mainly concentrated in the first section 431. Compared with the notch 433 being only set in the second section 432, the notch 433 being only set in the first section 431 can effectively reduce the yield stress; if the notch 433 is set in both the first section 431 and the second section 432, the shielding portion 45 is also set on one side of the second section 432 to shield the notch 433, and the grounding accommodating groove 1421 simultaneously accommodates the shielding portion 45 and the second section 432, which will affect the size and structural strength of the grounding accommodating groove 1421. Therefore, compared with the notch 433 being set in the first section 431 and the second section 432 at the same time, the notch 433 of the present application is only set in the first section 431, and the shielding portion 45 is located on one side of the first section 431 along the left-right direction, and the shielding portion 45 and the first section 431 are located outside the grounding accommodating groove 1421, which can avoid affecting the size and structural strength of the grounding accommodating groove 1421.
