Fluid connectors are usually used at the connection between the cooling mechanism and the main circulation system in the liquid cooling system. As a key component of the liquid cooling system, the cooling mechanism is equipped with heating components and allows it to exchange heat with its own internal coolant to achieve The purpose of heat dissipation and cooling.

Generally, the cooling mechanism is equipped with the male end of the fluid connector, and the main system is equipped with the female end of the fluid connector. During the manufacture and operation of application equipment, the cooling mechanism as a key component will involve countless operating tests including sealing, heat transfer performance, and related tests of heating elements on the cooling mechanism and their repair and maintenance in later operation ,replace. In these processes, it is necessary to unplug the fluid connector, and usually the cooling system is only in a shutdown state, and the pressure is not completely unloaded. At the same time, there is a certain residual pressure inside the unplugged cooling mechanism, which makes the fluid Connectors need to be unplugged under pressure.

In the prior art, both the male end joint and the female end joint of the fluid connector are provided with a movable spool, and the movable spool is arranged on the compression spring, and the other point of the compression spring is provided with a spring retaining ring or a fixed spool, and finally through The snap ring is stuck on the spring retainer or the end of the fixed valve core to achieve a fixed effect. With the current development trend of equipment miniaturization and modularization, the direct connection space between the male end and the female end of the connector is also greatly reduced. Radial floating space would otherwise require high precision in the mounting holes of the fluid connectors.

Most of the floating blind mate connectors now have a small floating amount, such as a commonly used floating blind mate connector with application number ZL201310567735.8 and a quick connector with application number 201610467763.6. The flexibility of the sealing ring is used to achieve the floating effect of the connector, and the floating amount is less than At the same time, this type of connector does not have the function of plugging and unplugging under pressure. Although the three types of joints with the application number 201510897675.5, the application number 201610470501.5 and the application number CN201811208734.3 can be plugged and unplugged under pressure, they have complex structures, large volumes, many parts, difficult processing and assembly, and are easily damaged when used. There are no connectors with smaller diameters, which is why this type of connectors are basically not seen on the market. In addition, there are some joints that can have a large radial float, such as a blind mating joint with a large radial float, such as the application number 201410786860.2 and the application number 201710296694.1. This type of fluid connector has a large radial Floating, the amount of floating can reach twice that of ordinary connectors, but it takes up a lot of space in the axial direction, and about 3/4 of the male end of the connector occupies the external space. And this type of connector also does not have the function of plugging and unplugging under pressure.

During the further insertion process, the inner sealing ring of the female end slides through the small flow channel hole on the female end spool that runs from the inside to the outside, and then the male end sealing ring also slides through the small flow hole on the female end spool that runs from the inside to the outside. The small channel hole makes the male end connector and the female end connector in a state of communication. During the connection process, all sealing rings are not exposed to the flow channel, so they will not be impacted by high-pressure fluid, which solves the current problem of fluid connectors being plugged and unplugged under pressure.

When the male and female connectors of the fluid connector are disconnected, each spring will spring back to the positioning position to ensure the original sealing surface and ensure that the circuit does not leak.

One or more technical solutions provided by this application have at least the following technical effects or advantages:

(1) The fluid connector in the present invention can realize plugging and unplugging under pressure; the main reason for realizing plugging and plugging under pressure is that the sealing ring is not exposed to the flow channel during the connection process and will not be impacted by the high-pressure fluid;

(2) The fluid connector in the present invention can be plugged and unplugged with a large float; to realize a large floating plug and plug, one is to rely on the groove of the connector plug-in guide slope at the right end of the main shaft sleeve at the female end, and the other is to rely on the floating structure of the male end so that The male-end floating retaining ring drives the male-end main shaft sleeve, and the male-end valve core relies on the male-end mounting nut to have a movable space of at least ±1mm. When the male-end floating retaining ring and the floating positioning boss of the male-end mounting nut have more space up and down And when the groove of the connector plug-in guide slope at the right end of the main shaft sleeve at the female end is larger, the floating amount of the connector can be larger.
