Since the first body 12 and the second body 22 are not easy to be dislocated, the sealed connection between the first body 12 and the second body 22 can be ensured.

On the other hand, since the floating end follows the fixed end to adjust its position, there will be a force to return to the original position at the floating end, so that there will be an interaction force perpendicular to the connection direction between the first body 12 and the second body 22. During long-term use , the first body 12 and the second body 22 are easily deformed gradually, resulting in reduced sealing between the first body 12 and the second body 22; and, when there is an elastic seal between the first body 12 and the second body 22 , the interaction force perpendicular to the connection direction between the first body 12 and the second body 22 will cause the elastic seal to be in a state of excessive local stress for a long time, resulting in excessive local deformation of the elastic seal and irreversibility, the elastic seal The tightness of the parts is reduced. In the embodiment of the present application, since the male end 1 and the female end 2 will not shift relative to each other under the restriction of the first guide part 13, the force of returning to the original position generated by the floating end of the male end 1 and the female end 2 is controlled by the first guiding part 13. A guide part 13 bears, effectively reduces or even eliminates the interaction force perpendicular to the connection direction between the first body 12 and the second body 22, so that the first body 12 and the second body 22 are not easily deformed after long-term use, and the elastic seal It is not easy to fatigue due to excessive local deformation, thereby improving the sealing performance of the connector.
