[0054] like Figures 4 to 8As shown, after the first connector 100 and the second connector 200 are connected in the up-down direction, the signal exposed portion 31 elastically abuts against the circuit board 400 downward, the ground exposed portion 21 abuts against the grounding member 5, and the signal exposed portion 31 is located in the common projection of the ground exposed portion 21 and the grounding member 5 in the left-right direction. Specifically, the first contact wall 2111 abuts against the first abutting portion 511 in the front-to-back direction, and the second contact wall 2121 abuts against the second abutting portion 512 in the up-to-down direction. The contact position of the first contact wall 2111 and the first abutting portion 511 in the left-to-right direction is located in the projection of the first shielding wall 2112. The second abutting portion 512 guides the circuit board 400 downward, and the partition rib 422 is located between the two signal exposed portions 31 of the differential signal pair. The partition rib 422 is engaged with the card slot 222 of the base 22, and the base 22 can extend downward without being blocked by the partition rib 422. The shielding member 4141 is located between the two shielding parts 221.

The main body 52 and the base 22 can cooperate to shield the multiple signal welding wire parts 32 from the front-to-back direction, effectively reducing the signal interference emitted by the signal welding wire parts 32. The main body 52 exceeds the signal welding wire parts 32 upward and downward, ensuring that the main body 52 can shield multiple signal welding wire parts 32 in the up and down directions, more effectively reducing the signal interference emitted by the signal welding wire parts 32.

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

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

[0057] 2. By arranging the first elastic hole 5111 and the second elastic hole 5121 to be connected to each other, the abutment elasticity of the first elastic part 5112 and the second elastic part 5122 can be enhanced to ensure the abutment stability. 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 abutment of the first contact wall 2111 and the second contact wall 2121.

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

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

[0060] 5. After the first connector 100 and the second connector 200 are docked in the up-down direction, a plurality of signal welding wire portions 32 are located between the main body portion 52 and the base portion 22 in the front-to-back direction. The main body portion 52 and the base portion 22 cooperate with each other to shield the signals emitted by the plurality of signal welding wire portions 32 from the front-to-back direction, thereby effectively reducing the signal interference emitted by the signal welding wire portions 32. The main body portion 52 exceeds the signal welding wire portion 32 upward and downward, thereby ensuring that the main body portion 52 can shield the plurality of signal welding wire portions 32 in the up-down direction, thereby more effectively reducing the signal interference emitted by the signal welding wire portions 32.

Therefore, all equivalent technical changes made by using the description and illustrations of this creation are included in the patent scope of this creation.
