Description

A floating blind plug fluid connector

technical field

The utility model relates to the field of fluid connectors, in particular to a floating blind plug fluid connector.

Background technique

With the trend of miniaturization and modularization of military equipment in our country, the power density of equipment is getting higher and higher, so the heat dissipation requirements for electronic equipment are also increasing. Air cooling has been replaced by a new cooling system - liquid cooling. At present, many key model projects in my country are using liquid cooling systems. The fluid connector is used to quickly connect or disconnect the coolant circulation system between different high-power modules or between the module and the equipment rack. It is a connector that can realize the fluid connection or disconnection of the pipeline without tools. It is a liquid cooling key elements of the system. Fluid connectors are divided into bayonet connectors, blind plug connectors and push-pull connectors according to the connection method. The ring is sealed. The sealing principle is: the plug and socket of the fluid connector are each equivalent to a one-way valve, with a valve core inside, a sealing ring on the plug valve core, and a sealing ring on the socket guide post. When not plugged in, The one-way valve closes automatically, the plug and the socket are sealed, and the liquid in the pipeline cannot flow out. When the plug is pushed into the socket, the spring is compressed, and the spools of the plug and socket are pushed open at the same time, the pipeline is connected, and the fluid can be released. circulation. The floating principle of the floating blind plug fluid connector is: there is a sealing ring in the lower part of the valve body and the connecting sleeve. Using the elasticity of the sealing ring, when there is a gap between the bottom of the valve body and the bottom of the mounting hole, the two sealing rings form a floating joint together. Structure, the valve body can have a certain float in the installation hole. The floating amount is determined by the gap between the structural parts and the wire diameter of the sealing ring. Since the sealing ring on the valve body acts as a seal at the same time, it forms a radial outer peripheral seal (piston seal) with the wall of the installation hole. Therefore, products with this structure The radial floating amount will not be very large. When the plug and socket have the floating function at the same time, the floating amount can reach up to φ0.5mm. Because of the small size of the fluid connector with a diameter of 3mm, the diameter of the sealing ring is thin. To ensure the sealing, generally use The socket is fixed and the plug is floating, and the floating amount can only reach φ0.2mm. Considering the tolerance distribution of each size, the mounting holes for installing fluid connectors are required to have high machining accuracy, so users very much hope to have a blind plug fluid connector with a large floating amount, which can reduce the machining dimensional accuracy and save costs.

The utility model patent application number ZL201310567735.8 discloses a floating blind plug fluid connector which is divided into two parts: a plug and a socket. Generally, plugs and sockets of products with diameters above 5mm adopt a floating structure. Fluid connectors with a diameter of 3mm are small in size and the diameter of the sealing ring is thin. To ensure sealing, the structure of fixed socket and floating plug is generally adopted. As shown in Figure 1, the plug is mainly composed of a pressure sleeve 15, a first snap ring 14, three sealing rings 3, a first connecting sleeve 17, a first valve core 13, a first valve body 11 and a spring 16. The first connecting sleeve 17 The interface thread adopts metric fine thread, which is used to install the plug in the installation hole of the module. There is a sealing ring 3 in the front end of the first valve body 11 and the first connecting sleeve 17 respectively. Using the elasticity of the sealing ring 3, when the first When there is a gap between the front end of the valve body 11 and the mounting hole, the two sealing rings form a floating structure together, and the valve body 11 can float in the mounting hole to a certain extent, and the floating amount is determined by the gap between the structural parts and the wire diameter of the sealing ring Decision; the sealing ring 3 between the first valve core 13 and the first valve core 11 and the first valve core 13 seal the first valve body 11 under the action of the spring force when the plug and the socket are not mated, forming a radial Peripheral seal (piston seal), the sealing ring 3 at the front end of the valve body 11 acts as a seal at the same time, and forms a radial peripheral seal (piston seal) with the wall of the installation hole, so that the liquid inside the system will not leak. As shown in Figure 2, the socket is mainly composed of four sealing rings 3, the second valve core 23, the second valve body 21, the guide column 25, the second connecting sleeve 27, the second spring 26 and the second snap ring 24; and the plug Similarly, the thread of the second connection sleeve 27 adopts metric fine thread, which is used to install the socket in the mounting hole of the frame, and a sealing ring 3 is respectively installed in the rear end of the second valve body 21 and the second connection sleeve 27 , using the elasticity of the sealing ring, when there is a gap between the rear end of the second valve body 21 and the mounting hole, the two sealing rings 3 play the role of floating, and the second valve body 21 can have a certain amount of floating in the mounting hole. The size of the seal ring is determined by the gap between the structural parts and the wire diameter of the seal ring. The seal ring 3 at the rear end of the second valve body 21 acts as a seal at the same time, and forms a radial peripheral seal (piston seal) with the wall of the installation hole; the second valve core 23 1. The sealing ring 3 in the second valve body 21 and the sealing ring 3 on the guide column seal the second valve body 21 under the action of spring force when the plug and the socket are not mated, forming a radial outer peripheral seal (piston seal ) and inner peripheral seal (piston rod seal); one end of the second spring 26 is positioned by the second valve core 23, the other end is fixed by the guide post 25, and the guide post 25 is fixed on the second valve body by the second snap ring 24 Within 21. The floating of the above-mentioned fluid connector is due to the elasticity of the two sealing rings leaning against the valve body and the corresponding connecting sleeve. When there is a gap between the valve body and the mounting hole, the two sealing rings together form a floating structure, and the valve body can float to a certain extent in the mounting hole. The amount of floating is determined by the gap between the structural parts and the wire diameter of the sealing ring. The product with this structure will not have a large radial floating amount, which cannot meet the requirements for applications with large floating amount.
