The upper end of the sealing ring 2 is set as a tubular structure, and the lower end is provided with a tubular skirt 3. The thickness of the skirt 3 is thinner than that of the sealing ring 2, and at least two protrusions 4 are provided at the end of the skirt 3 away from the sealing ring 2. The protrusions 4 extend from the skirt 3 to the socket base shell 1, and there is a certain gap between adjacent protrusions 4, so that the button-type fluid connector is plugged and unplugged under pressure. In the connected state, the liquid can flow back to the cavity from the notch position at the cross section, thereby preventing leakage caused by liquid splashing caused by pressure and ensuring the sealing of the connector product.

[0034] Optionally, the sealing ring 2 can be cut and modified from an existing sealing ring, that is, the raised portion at the end of the skirt 3 can be cut along a plane tangent to the side of the sealing ring 2. This allows the sealing ring that has been manufactured but not assembled to be modified, thereby reducing costs.

In the prior art, the raised portion 4 at the end of the skirt 3 of the sealing ring 2 enables the sealing ring 2 to play a sealing role, while the structural strength of the raised portion 4 of the present application is reduced after the improvement, which can easily cause deformation of the sealing ring 2 under high pressure. Therefore, a plurality of support members 5 are arranged to improve the overall structural strength and extend the service life.

[0038] On the basis of the above embodiment, the protrusion 4 is an arc-shaped protrusion, the width of the protrusion 4 in the horizontal direction gradually decreases from the skirt 3 to the socket base housing 1, and the radius of the protrusion 4 is greater than the radius of the sealing ring 2.
