The second elastic hole 5121 is located on the side of the second elastic portion 5122 away from the second contact wall 2121. The second elastic hole 5121 increases the elasticity of the second elastic portion 5122, which is beneficial to the stability of the second elastic portion 5122 abutting against the second contact wall 2121. The second elastic hole 5121 is located within the projection of the second shielding wall 2122 in the left-right direction, which can reduce the signal interference caused by the signal emitted by the signal exposed portion 31 passing through the second elastic hole 5121 to other signal exposed portions 31.

[0054] like Figures 4 to 8As shown, after the first connector 100 and the second connector 200 are mated in the vertical direction, the signal exposed portion 31 elastically abuts downward against the circuit board 400, and the ground exposed portion 21 abuts against the grounding component 5. In the horizontal direction, the signal exposed portion 31 is located within the common projection of the ground exposed portion 21 and the grounding component 5. Specifically, in the front-back direction, the first contact wall 2111 abuts against the first supporting portion 511, and in the vertical direction, the second contact wall 2121 abuts against the second supporting portion 512. In the horizontal direction, the contact position of the first contact wall 2111 and the first supporting portion 511 is located within the projection of the first shielding wall 2112. The second supporting portion 512 is guided downward to the circuit board 400. The separating rib 422 is located between the two signal exposed portions 31 of the differential signal pair. The separating rib 422 engages with the slot 222 of the base 22, allowing the base 22 to extend downward without being obstructed by the separating rib 422. The shielding member 4141 is located between the two shielding parts 221. Along the front-to-back direction, the shielding member 4141 shields multiple slots 222, reducing signal interference emitted by the exposed signal parts 31 through the slots 222. The bottom surfaces of multiple second notches 4222 abut against the first insulating body 1, providing support and preventing tilting. Multiple support parts 423 abut against the first insulating body 1, serving not only to fix the grounding support part 51 but also to support the first insulating body 1, preventing tilting. Furthermore, viewed from the left-to-right direction, the base 22 extends downwards beyond the contact position of the second contact wall 2121 and the second support part 512, allowing for greater shielding against signal interference emitted between the exposed signal parts 31 of the two rows of differential signal pairs. The first plate surface 3111 abuts downward against the circuit board 400. The base 22 extends downward between the first plate surface 3111 and the second plate surface 3112. The base 22 can shield more effectively from signal interference emitted between the exposed signal portions 31 of the two rows of differential signal pairs. Multiple signal bonding portions 32 are located between the main body 52 and the base 22 along the front-to-back direction. The main body 52 and the base 22 work together to shield the multiple signal bonding portions 32 from the front-to-back direction, effectively reducing signal interference emitted by the signal bonding portions 32. The main body 52 extends upward and downward beyond the signal bonding portions 32, ensuring that the main body 52 can shield the multiple signal bonding portions 32 along the vertical direction, further effectively reducing signal interference emitted by the signal bonding portions 32.

[0055] In summary, the connector assembly of the present invention has the following beneficial effects:

[0056] 1. The shielding component 2 includes a plurality of exposed ground portions 21 arranged in the left-right direction and a base 22 integrally connected to the plurality of exposed ground portions 21. The base 22 is located between the exposed signal portions 31 of two rows of differential signal pairs in the front-back direction. After the first connector 100 and the second connector 200 are mated in the vertical direction, the exposed signal portions 31 in the left-right direction are located within the common projection of the exposed ground portions 21 and the grounding component 5. The exposed ground portions 21 and the grounding component 5 work together to shield the exposed signal portions 31 of the differential signal pairs from three sides, reducing crosstalk between the exposed signal portions 31 of different differential signal pairs. The base 22 and the exposed ground portions 21 are integrally connected, and the connection position of the base 22 and the exposed ground portions 21 can also shield the exposed signal portion 31 of a differential signal pair, reducing the exposure of different differential signal pairs. Crosstalk between parts 31; the ground exposed part 21 includes a first groove 211 recessed in the front-back direction. The first groove 211 includes a first contact wall 2111 and a first shielding wall 2112 connecting the first contact wall 2111. The contact position of the first contact wall 2111 and the first abutment 511 in the left-right direction is located within the projection of the first shielding wall 2112, reducing the signal interference caused by the signal emitted by the signal exposed part 31 passing through the contact position of the first contact wall 2111 and the first abutment 511 to other signal exposed parts 31; the first contact wall 2111 abuts the first abutment 511 in the front-back direction, and the second contact wall 2121 abuts the second abutment 512 in the up-down direction, which can not only ensure the contact stability between the ground exposed part 21 and the grounding member 5, but also realize multi-point contact and increase the grounding area.

[0057] 2. By setting the first elastic hole 5111 and the second elastic hole 5121 to be interconnected, the abutting elasticity of the first elastic part 5112 and the second elastic part 5122 can be enhanced to ensure stable abutting. At the same time, it is also beneficial to the stability of the position where the first elastic part 5112 and the second elastic part 5122 are connected to the position where the first contact wall 2111 and the second contact wall 2121 are connected.

[0058] 3. The second elastic hole 5121 is located between the second elastic part 5122 and the third elastic part 5123. The second elastic hole 5121 can not only increase the elasticity of the second elastic part 5122, but also increase the elasticity of the third elastic part 5123, which is beneficial to the stability of the third elastic part 5123 abutting against the circuit board 400.

[0059] 4. The separator rib 422 is located between the two exposed parts 31 of the same differential signal pair, which can increase the dielectric constant between the two exposed parts 31, thereby increasing the capacitance between the two exposed parts 31, thereby weakening the signal emitted by the differential signal, and ultimately reducing the crosstalk between different differential signal pairs.

[0060] 5. After the first connector 100 and the second connector 200 are mated in the vertical direction, multiple signal bonding sections 32 are located between the main body 52 and the base 22 in the front-back direction. The main body 52 and the base 22 work together to shield the signals emitted by the multiple signal bonding sections 32 from the front-back direction, effectively reducing the signal interference emitted by the signal bonding sections 32. The main body 52 extends upward and downward beyond the signal bonding sections 32, ensuring that the main body 52 can shield the multiple signal bonding sections 32 in the vertical direction, further effectively reducing the signal interference emitted by the signal bonding sections 32.

Therefore, all equivalent technical changes made using the content of this invention's specification and illustrations are included within the patent scope of this invention.
