Miniature fluid connector and miniature fluid connector assembly

The invention provides a miniature fluid connector and a miniature fluid connector assembly. The miniature fluid connector comprises valve bodies, valve cores arranged in the valve bodies and elasticmembers, the outer portion of each valve body is sleeved with a mounting shell in an axial direction, an annular floating gap is formed between the inner wall surface of the mounting shell and the outer peripheral surface of each valve body, the floating gap is separated by an elastic sealing ring arranged between each valve body and the mounting shell, and the plug-in end of each valve body is provided with a radial deviation rectifying structure used for being matched with an adapter connector. When the miniature fluid connector and the matched connector are mutually inserted, each valve body can be radially offset under the action of the radial deviation rectifying structure so that the miniature fluid connector is in proper butt joint with the matched connector, the sealing between each valve body and the moun
