Of course, other types of axial elastic members such as elastic rubber may be used instead of the compression spring.

In this embodiment, the male connector housing 11 has a front limit position and a rear limit position in the axial direction, when the male connector housing 11 is located at the front limit position, the rear limit surface 116 on the male connector housing 11 is in limit fit with the mounting sleeve fitting surface located at the rear side to limit the male connector housing 11 from moving forward, and when the male connector housing 11 is located at the rear limit position, the front limit surface 117 on the male connector housing 11 is in limit fit with the mounting sleeve fitting surface located at the front side.

In the present embodiment, there are both axial floating gaps and radial floating gaps between the male connector housing 11 and the male connector mounting sleeve 13, and in other embodiments, only axial floating gaps or only radial floating gaps may be provided therebetween as required.

The female joint 2 is also a floating fluid joint, the female joint 2 further comprises a female joint mounting sleeve 23, the female joint mounting sleeve 23 is in floating fit with the female joint shell 21, the specific fit relation is the same as the fit relation of the male joint mounting sleeve 13 and the male joint shell 11, the specific floating structure on the female joint 2 is the same as the floating structure of the male joint 1, details are omitted, and the mounting environment with larger errors can be adapted when the female joint 2 and the male joint 1 are both floating fluid joints.

In the embodiment of the floating fluid connector of the present invention, the structure of the floating fluid connector in this embodiment is the same as the structure of the male connector or the female connector described in the above embodiment of the connector assembly, and details are not repeated.
