Wherein, the X-axis, Y-axis and Z-axis are perpendicular to each other.

[0037] Please refer to Figure 1 and Figure 9 As shown in the figure, it is a floating shield connector assembly disclosed by the present application, comprising: an insulating body 1, a plurality of terminals 2 fixed with the insulating body 1, a docking substrate 3 and a shielding shell 4. Wherein the docking substrate 3 can be a adapter board, but also can be a circuit substrate inside the device. Specifically, the insulating body 1 is made of insulating material by injection molding and is defined to form a front end face 101 and a rear end face 102 corresponding to the front-back direction, a left side face 103 and a right side face 104 corresponding to the left-right direction perpendicular to the front-back direction, and an upper end face 105 and a lower end face 106 corresponding to the up-down direction perpendicular to the front-back direction and the left-right direction. The insulating body 1 is formed with a plurality of terminal holes 10 along the front-back direction.

[0038] Wherein, each terminal 2 includes a terminal spring segment 21, a terminal implant segment 22 connected to one end of the terminal spring segment 21, and a terminal connecting segment 23 connected to the other end of the terminal spring segment 21, at least part of the terminal implant segment 22 is implanted and fixed to the insulating body 1. The terminal spring segment 21 is preferably designed to be a circuitous curved shape of non-linear extension, so as to be able to realize elastic deformation in multiple directions. The terminal implant segment 22 integrally extends a contact portion 24, and the contact portion 24 is configured to be used for docking with a docking connector (not shown).

[0039] The terminal connecting sections 23 are correspondingly connected and fixed to the docking substrate 3. The terminal spring sections 21 are elastically deformable to enable the whole insulation body 1 to float relative to the docking substrate 3. Further, the plurality of terminals 2 include at least two signal terminals 201 and one shielding terminal 202. The terminal implant sections 22 of the at least two signal terminals 201 are arranged side by side.

In a preferred embodiment, the terminal spring sections 21 of the shielding terminal 202 are four, two of which are integrally connected to the front end edges of the terminal implant section 22 and arranged in the left-right direction, and the other two of which are integrally connected to the rear end edges of the terminal implant section 22 and arranged in the left-right direction. Each of the terminal spring sections 21 of the shielding terminal 202 is formed with at least one terminal connecting section 23 (in the illustrated embodiment, each of the terminal spring sections 21 of the shielding terminal 202 is formed with one terminal connecting section 23).
