[0042] Please refer to Figure 1 and Figure 9 for a floating connector assembly disclosed in the present application, which comprises an insulating body 1, a plurality of terminals 2 fixed to the insulating body 1, a mating substrate part 3 and a shielding shell 4. The mating substrate part 3 can be a conversion board or a circuit substrate inside a device. Specifically, the insulating body 1 is made of an insulating material by injection molding and is defined to have a front end surface 101 and a rear end surface 102 corresponding to the front-back direction, a left side surface 103 and a right side surface 104 corresponding to the left-right direction perpendicular to the front-back direction, and an upper end surface 105 and a lower end surface 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 penetrating in the front-back direction.

[0043] Each terminal 2 comprises 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, and 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 in a meandering curved shape extending in a non-straight line, so as to be capable of elastic deformation in multiple directions. An integrated contact part 24 is formed on the terminal implant segment 22, and the contact part 24 is configured to mate with a mating connector (not shown).
