AI Technical Summary

Technical Problem

Existing fluid connectors have low spring motion stability, are prone to scraping the walls, resulting in unstable connections and unreliable seals.

Method used

A fluid connector is designed in which the first end face of the plug's movable valve core abuts against the first end of the plug spring and fully covers the projected contour of the plug spring. The support part is clearance-fitted with the inner wall of the plug housing to form a stable support structure. The socket assembly adopts a double sealing structure and a rolling element limiting groove to ensure a reliable connection between the plug assembly and the socket assembly.

Benefits of technology

This improves the connection stability and sealing reliability of the fluid connector, prevents the spring from scraping against the inner wall of the housing during extension and retraction, and ensures smooth fluid transmission and zero leakage.

Abstract

The application discloses a fluid connector and a liquid cooling system. The fluid connector comprises a plug assembly, a plug movable valve core and a first spring. The plug assembly is internally formed with a plug fluid passage. The plug movable valve core and the first spring are arranged in the plug fluid passage. When the plug fluid passage is in a cut-off state, the plug movable valve core seals the plug fluid passage. The first end of the first spring is connected to the plug movable valve core and the inner wall of the plug housing. The first direction is the axis direction of the plug fluid passage. The plug movable valve core has a first end face in the first direction. The first end face is in abutment with the first end of the first spring. The plug movable valve core is configured to support the first spring in the first direction. The projection profile of the first end face in the first direction covers the projection profile of the first spring in the first direction. The fluid connector provided by the application can improve the connection stability.
