[0036] like Figure 3 , Figure 4 and Figure 5 As shown, the conductive shielding component 3 is located between two adjacent signal terminals 2. Specifically, two adjacent signal terminals 2 along the second direction among the multiple signal terminals 2 form a signal terminal pair, and the conductive shielding component 3 is located between the two adjacent signal terminal pairs, and the projection of the conductive shielding component 3 along the second direction overlaps with the projection of the signal body 21. The grounding member 4 is fixed to the conductive shielding member 3, and along the third direction, the projection of the grounding member 4 overlaps with the projection of the conductive shielding member 3.

[0044] In summary, the present invention has the following effects:
[0045] 1. The conductive shielding member 3 is arranged between two adjacent signal terminals 2, and the projection of the conductive shielding member 3 along the second direction overlaps with the projection of the signal body 21, and the projection of the second bent portion 411 of the grounding member 4 along the second direction overlaps with the projection of the first bent portion 221 of the signal terminal 2, that is, the conductive shielding member 3 shields the signal body 21, and the grounding member 4 shields the first bent portion 221, and the conductive shielding member 3 and the grounding member 4 cooperate with each other, and both shield the signal terminal 2 in the second direction at the same time; on this basis, after the docking element 200 is inserted into the slot 11, the outer arc surface 413 abuts against the arc surface 311, which not only shortens the grounding loop from the second contact portion 4121 to the conductive shielding member 3, but also the arc surface to arc surface design can make the gap between the conductive shielding member 3 and the grounding member 4 smaller, thereby enhancing the shielding effect of the conductive shielding member 3 and the grounding member 4, and can better reduce the crosstalk received by the signal terminal in the second direction and eliminate resonance.
[0046] 2. The curvature of the abutting arc surface 311 is consistent with the curvature of the outer arc surface 413. After the outer arc surface 413 abuts against the abutting arc surface 311, the outer arc surface 413 is basically in contact with the abutting arc surface 311, that is, there is almost no gap between the outer arc surface 413 and the abutting arc surface 311, which enhances the shielding effect of the conductive shielding member 3 and the grounding member 4 on the signal terminal 2. The conductive shielding member 3 has a corresponding structure with the same profile as the grounding spring arm 41, the extension part 42, and the fixing part 43 on the side close to the slot 11, and the corresponding structure of the conductive shielding member 3 is in contact with the grounding spring arm 41, the extension part 42, and the fixing part 43 one by one, which makes the conductive shielding member 3 and the grounding member 4 closely combined, and the two have multiple contact points, which further enhances the shielding effect of the conductive shielding member 3 and the grounding member 4.
[0047] 3. A first clamping portion 44 is provided at the end of the grounding member 4 to clamp the connecting portion 32, so that the end of the grounding member 4 is connected to the conductive shielding member 3. While adding a new grounding loop, the induced current at the end of the grounding member 4 is prevented from gathering to form a new interference source, thereby enhancing the shielding effect of the grounding member 4 and eliminating resonance.
[0048] 4. The first shielding member 5 can shield the signal terminal 2 in the third direction, and the first shielding member 5 is provided with a second clamping portion 52 fixed to the conductive shielding member 3, and the second clamping portion 52 clamps the top of the conductive shielding member 3, so that the top of the conductive shielding member 3 is connected to the first shielding member 5, and the induced current gathered at the top of the conductive shielding member 3 can be discharged through the second clamping portion 52, so that the shielding combination effect of the first shielding member 5 and the conductive shielding member 3 is better. The second shielding member 6 has two side plates 61 located between the conductive shielding member 3 and the shielding plate 51, so that the side plates 61 are filled in the gap between the first shielding member 5 and the conductive shielding member 3, further improving the shielding effect of the signal terminal 2 and reducing crosstalk.
[0049] 5. A stopper 131 is provided in the signal receiving slot 13. A slope 1311 extending close to the slot 11 is provided near the slope 222 of the stopper 131. The slope 1311 can limit the slope 222 to prevent excessive deformation of the signal terminal 2 when the docking element docks with the slot 11. On the other hand, the stopper 131 can adjust the impedance of the signal terminal 2 to match the impedance of the slope 222 of the signal terminal 2 and the signal body 21, thereby improving the high-frequency performance of the connector. The insulating member 7 has a protruding portion 72 extending in the direction close to the slope 222. The slope 222 of the signal terminal 2 is located between the protruding portion 72 and the slope 1311. The protruding portion 72 can further limit the signal terminal 2 and adjust the impedance of the signal terminal 2.
