A micro-miniature pressurized plug fluid connector

Abstract

A micro-miniature pressurized plug fluid connector, including a plug and a socket, the plug includes a plug housing and a sealing assembly, the sealing assembly includes a sleeve and a sealing block, the rear end of the plug housing is provided with a positioning sleeve, and the positioning sleeve passes through the first The spring is in contact with the sleeve, the inner wall of the front end of the plug housing is provided with a first limiting part, and the first sealing ring is provided between the sealing block and the plug housing; the socket includes a socket housing and a sealing rod assembled in the socket housing, The sealing rod is covered with a second spring and a sealing ring. The front end of the second spring is in contact with the sealing ring, and the rear end is in contact with the sealing rod. The sealing ring forms a seal with the sealing rod, and the front end of the sealing rod is provided with a plurality of through holes. The invention does not expose any sealing ring to the fluid during operation, thereby avoiding the sealing ring from being washed away; in addition, the special sealing component not only improves the stability of the connector, but also reduces the flow resistance of the fluid and improves the fluid flux.

Description

technical field [0001] The invention belongs to the technical field of fluid connectors, in particular to a miniature pressurized plug fluid connector. Background technique [0002] With the continuous development of high-frequency, high-density, and high-integration electronic components in equipment, the problem of how to achieve efficient heat dissipation for equipment is becoming more and more prominent. Liquid cooling technology has become the first choice to solve this problem. Liquid cooling technology has been widely used in aviation, aerospace, electronics, ships, communications, wind power, electric vehicles and other fields. [0003] With the development of technology, electronic equipment tends to be miniaturized, and there is an urgent need for micro-miniature fluid connectors to realize the transmission of fluid between the cooled module and the chassis, but such existing connectors have the following problems during operation: [0004] 1. The size of the O-ri...

AI Technical Summary

Problems solved by technology

[0004] 1. The size of the O-ring of the miniature fluid connector is small, and the O-ring is easily washed out during the plugging and unplugging process, resulting in seal failure

[0005] 2. Due to the size limitation of micro-miniature fluid connectors, adding an O-ring protection sleeve structure will affect the flow performance of the connector

However, in actual use, it is found that the structure of using a separate sealing block and spring is not stable. Due to the fast internal liquid circulation and strong impact force when the connector is working, it will continuously impact the sealing block set in the center of the fluid channel through the spring. In addition, the sealing block needs to form a liquid channel with the plug housing, so the sealing block does not contact the inner wall of the plug housing, which provides space for the radial displacement of the sealing block under the action of external force

The above comprehensive factors may cause the sealing block to be impacted by high-speed liquid, causing its radial displacement or even breaking away from the spring
