The invention discloses an embedded fluid connector capable of large floating and the spring is not exposed to the flow channel, comprising a male end connector and a female end connector matched with the male end connector, the male end connector includes a male end main shaft sleeve And the male end mounting nut, the female end connector includes the first female end spindle sleeve and the second female end spindle sleeve, when the male end connector and the female end connector are connected, the male end spindle sleeve extends into the second female end spindle sleeve and push the sleeve of the female end spool to move, and at the same time, the female end spool pushes the male end spool to move, so that the flow channels in the female end connector and the male end connector are in a connected state, because the male end spring is sleeved on the male end On the spool, the female end spring is sleeved on the female end spool shaft sleeve, so that when the female end connector and the male end connector are in a connected state, the influence of the male end spring and the female end spring on the flow in the flow channel is avoided, and at the same time, it is avoided. The spring is made of higher material, which saves cost and has a larger floating amount.
