Since the impedance of the first contact portion 411 is lowered after the first contact portion 411 is overlapped by the thickness of the second contact portion 711, the first distance L1 is greater than the second distance L2, the distance between the first contact portion 411 and the first shielding shell 42 can be increased, the impedance of the first contact portion 411 can be increased, the impedance difference between the first contact portion 411 and the first connecting portion 412 can be prevented from being too low, and the impedance consistency of the first signal terminal 41 can be improved. In this embodiment, the first shielding shell 42 includes two U-shaped shielding bodies 425 which are disposed oppositely and assembled with each other, and the side surfaces of the two U-shaped shielding bodies 425 jointly form the first shielding side 423 and the second shielding side 424 of the first shielding shell 42, which can facilitate the assembly of the first signal terminal 41 into the first shielding shell 42, but of course, in other embodiments, the first shielding shell 42 may be an integrally formed tubular structure or assembled by a structure with other shapes, and is not limited herein.

Referring to fig. 3 to 5, 9 and 10, each of the second terminal assemblies 7 includes two second signal terminals 71, a second insulating block 73 covering the two second signal terminals 71, and a second shielding shell 72 covering the two second signal terminals 71 and the second insulating block 73. The two second signal terminals 71 of each second terminal assembly 7 are arranged along the second direction Y to form a second differential pair, and each second signal terminal 71 has a second contact portion 711, a second lead-in portion 713, and a second connection portion 712 connecting the second contact portion 711 and the second lead-in portion 713. The second contact portion 711 sequentially extends from the second connection portion 712 to form a second connection portion 7111, a third bending section 7112, a third contact section 7113, a fourth bending section 7114 and a fourth contact section 7115, the bending directions of the third bending section 7112 and the fourth bending section 7114 are the same, and the bending direction of the third bending section 7112 is opposite to the bending direction of the first bending section 4112. In this embodiment, the second lead portion 713 is soldered to the surface of the second substrate 11 along the first direction X by the solder ball 9, so as to improve the coplanarity of the second signal terminals 71.
Referring to fig. 9, the second shielding shell 72 has a third shielding side 723 and a fourth shielding side 724 oppositely disposed along the first direction X, and a third main body surface 721 and a fourth main body surface 722 oppositely disposed along the third direction Z. In the present embodiment, the second shielding shell 72 is enclosed outside the second connecting portion 712 and the second contact portion 711.
Referring to fig. 3 and 4, the second connection portion 713 extends from the second connection portion 712, and the second connection portion 713 is offset along the third direction Z with respect to a center line between the third body surface 721 and the fourth body surface 722. Since the characteristic impedance is increased at the moment when the signal is output from the second substrate 11 to the second conducting portion 713 of the second differential pair, the second conducting portion 713 is relatively offset from the center line between the third body surface 721 and the fourth body surface 722 along the third direction Z, so that the distance between the second conducting portion 713 and the second shielding shell 72 can be shortened, the impedance at the second conducting portion 713 can be reduced, and the problem that the impedance of the signal at the second conducting portion 713 is too large to cause large signal loss can be avoided. Further, the second connecting portion 712 and the second connecting portion 7111 are located at the same horizontal plane, the second guiding portion 713 is soldered on the second substrate 11 by a solder ball 9, and the second connecting portion 712 and the solder ball 9 overlap in the first direction X projection. When the first contact portion 411 and the second contact portion 711 are inserted into and removed from each other, the insertion and removal force applied to the second contact portion 711 is transmitted to the second connection portion 712 along the first direction X, and transmitted to the second guiding connection portion 713, compared with the second connection portion 712 and the solder ball 9 which are completely staggered in the first direction X, the second connection portion 712 and the solder ball 9 of the present invention have relatively small position deviation in the third direction Z, and more insertion and extraction force can act on the second guiding connection portion 713 along the first direction X, rather than more, the torsion force in the third direction Z or the second direction Y acts on the second guiding portion 713, so as to reduce the risk of the solder ball 9 being cracked or the second guiding portion 713 and the solder ball 9 being split when the first connector 200 and the second connector 300 are unplugged and plugged.

Therefore, the first pitch I1 provides a larger space for the solder balls 9 soldered by the two second lead portions 713, so as to prevent the two solder balls 9 from contacting each other and affecting signal transmission; meanwhile, since the impedance is larger as the pitch between two second signal terminals 71 is larger, the impedance is larger as the width of the second signal terminals 71 is larger, and the second contact part 711 is overlapped by the thickness of the first contact part 411 when transmitting signals, so that the thickness of the second contact part 711 is reduced, the first pitch I1> the second pitch I2> the third pitch I3, and the first width W1> the second width W2> the third width W3 of the present invention enable the impedance of the second lead part 713 to the second contact part 711 to gradually transition from large to small when transmitting signals at the second signal terminals 71, thereby avoiding the impedance from abrupt change at the second signal terminals 71 to cause signal distortion.

In this embodiment, each of the second insulating blocks 73 has two second supporting portions 732 respectively abutting against the third bent sections 7112 of the two second contact portions 711 of the second differential pair, but in other embodiments, each of the second insulating blocks 73 may also extend one second supporting portion 732 to simultaneously abut against the third bent sections 7112 of the two second contact portions 711. The second contact portion 711 is supported by the second support portion 732, so that elastic fatigue of the second contact portion 711 is avoided, and a support force is provided for the second contact portion 711 to make more stable contact with the first contact portion 411; meanwhile, the second supporting portion 732 extends beyond the third bent section 7112, so that the second signal terminal 71 can be prevented from being damaged due to the excessive bending of the third bent section 7112.

4. The position deviation of the second connection portion 712 and the solder ball 9 in the third direction Z can be relatively small, and the insertion/extraction force can act on the second connection portion 713 along the first direction X more, rather than turning to act on the second connection portion 713 more in the third direction Z or the second direction Y, so as to reduce the risk of the solder ball 9 being cracked or the second connection portion 713 and the solder ball 9 being split when the first connector 200 and the second connector 300 are inserted or extracted.
5. The third distance L3 is not greater than the fourth distance L4, the fifth distance L5 is not greater than the sixth distance L6, so as to avoid that the moment arm at the first position is too short and causes the second contact section 4115 to generate a large deformation when the first contact section 4113 deforms, and avoid that the moment arm at the second position is too short and causes the third contact section 7113 to generate a large deformation when the fourth contact section 7115 deforms, thereby further improving the stability of the double-point contact between the first contact part 411 and the second contact part 711.
