Description

Hose quick-insertion fluid connector

Technical Field

The invention relates to the technical field of connectors, in particular to a hose quick-insertion fluid connector.

Background

The fluid connector is generally used at the junction of a cooling mechanism and a main circulation system in a liquid cooling system, and generally consists of two parts, namely a socket of the cooling mechanism and a plug of the main circulation system. The cooling mechanism is used as a key part of the liquid cooling system, is provided with a heating element and exchanges heat with the cooling liquid in the cooling mechanism, so that the purposes of heat dissipation and cooling are achieved. Generally, the piping system of the better cooling mechanism is composed of a fluid connector, a rubber hose with a metal braid and a metal hard pipe, and the maximum working pressure of the internally circulated cooling liquid is generally 4 Mpa. The cooling mechanism is generally used in military industry or high-end high-power civil industry, has high cooling efficiency and relatively high cost. There are also relatively low end cooling mechanisms on the market which, due to cost constraints, choose to use standard plastic hoses on the market directly, with a maximum working pressure of 2 Mpa. In the choice of fluid connectors, there are generally two options: firstly, a fluid connector with the application number of 200910065155.2 or the application number of 201710496577.X and the like is selected to be buckled or locked by steel balls, and a cooling mechanism is formed by matching threaded buckling and hose connection. Such fluid connectors are costly and complicated to connect to the hose. And the second is that a pneumatic quick connector with the application number of 201610769945.9 is selected. The joint is commonly used in the pneumatic industry, the installation is convenient, the hose can be directly inserted into the connector, the cost is low, but the maximum working pressure is 0.9Mpa, and when the pressure is more than 0.9Mpa, the hose and the quick connector are easy to fall off to cause leakage. There is a need for a fluid connector that can meet a maximum operating pressure of 2Mpa, and that can be easily connected to a plastic hose at a relatively low cost.
