Description

Technical Field

[0001] This utility model belongs to the field of fluid connectors, and specifically relates to a self-sealing ferrule assembly for fluid connectors. Background Technology

[0002] With the continuous innovation and development of microelectronics and large-scale integration technologies, weapon systems are becoming increasingly integrated and miniaturized. This has led to the densification and miniaturization of electronic devices, but the heat generated per unit volume has increased exponentially. The installation of numerous electronic devices in confined spaces inevitably generates a large amount of heat, and overheating is one of the main causes of electronic device failure, severely reducing performance, reliability, and lifespan. Common cooling methods for electronic devices include air cooling and liquid cooling. Considering space and heat dissipation efficiency, most equipment has adopted liquid cooling systems in recent years. Fluid connectors are key components of liquid cooling system interfaces, playing a crucial role in ensuring reliable and effective operation of the liquid cooling system. The importance of fluid connectors within electronic devices lies in two aspects: First, if the fluid connector has poor sealing performance, coolant leakage can corrode nearby components or pollute the system environment, reducing insulation and voltage withstand performance, and in severe cases, causing short circuits or open circuits in the circuit system. Second, if the fluid connector is damaged, the liquid cooling system will experience poor flow, reducing the cooling effect, and in severe cases, causing the system equipment to burn out due to excessive temperature rise. Therefore, the most crucial aspect for this product is to have extremely high technical standards to support it, so as to improve its reliability in various environments. Summary of the Invention

[0018] Figure 2 This is a schematic diagram of the insertion of the pin body into the straight tube of the hole. Detailed Implementation

[0019] The following will be based on the embodiments of this utility model. Figure 1-Figure 2The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art. It should be noted that in this utility model, "front end" or "front" refers to the opposite end of the straight tube 3 and the pin body 8, such as... Figure 1 The right side of the straight tube 3 and the left side of the pin body 8; "rear end" and "rear" refer to the ends of the straight tube 3 and the pin body 8 that are opposite to each other, such as Figure 1 The left side of the straight tube 3 and the right side of the pin body 8.

[0020] like Figure 1 A self-sealing ferrule assembly for a fluid connector includes a straight tube 3, a spring 4, a plug 6, and a pin body 8;

[0021] The plug 6 is slidably disposed inside the straight tube 3. The plug 6 has a connecting hole 5 on its side. The inner wall of the straight tube 3 has an inner protrusion. The connecting hole 5 fits against the wall of the inner protrusion. The spring 4 is disposed at the rear end of the plug 6.

[0022] When the pin body 8 is inserted into the straight tube 3, the end of the pin body 8 abuts against the plug 6, and the connecting hole 5 is moved to the rear of the inner protrusion by pushing the plug 6, so that the straight tube 3, the connecting hole 5 and the pin body 8 are connected.

[0023] The rear ends of the straight tube 3 and the pin body 8 are used to introduce fluid, such as coolant; both are hollow structures. The straight tube 3 and the pin body 8 are used to insert and mate to form a connector structure, which is used to connect different pipelines to form a fluid transport function. Figure 2 The diagram illustrates the state when the two parts are inserted. The inner convex part is annular, and its inner diameter is smaller than that of the straight tube 3. When the connecting hole 5 is against the wall of the inner convex part, the connecting hole 5 is covered and sealed. When the pin body 8 is inserted into the straight tube 3, the pin body 8 pushes the plug 6 to move, and the spring 4 is compressed, thereby causing the connecting hole 5 to move out of the coverage area of ​​the inner convex part. Thus, the connecting hole 5 connects the straight tube 3 and the pin body 8. It should be noted that both the straight tube 3 and the pin body 8 are hollow structures. The end of the plug 6 facing the pin body 8 has a chamber, and the connecting hole 5 connects to the chamber of the plug 6. When the straight tube 3 and the pin body 8 are disengaged, the spring 4 returns to its original position, the plug 6 returns to its original position, and the straight tube 3 is resealed. In addition, a sealing ring can be provided at the rear end of the inner convex part to improve the sealing performance.

[0024] In this invention, the spring 4 holds the plug 6 in place, and the connecting hole 5 and the inner protrusion provide a sealing effect. The insert body 8 is inserted into and pushes the plug 6, causing the plug 6 to retract and allowing liquid to flow. This prevents liquid leakage and creates a self-sealing function.

[0025] Furthermore, the rear end of the straight pipe 3 is detachably connected to a pipe interface 1, which communicates with the straight pipe 3 and abuts against the rear end of the spring 4. The pipe interface 1 is used to connect to an external pipe.

[0026] Furthermore, the pipe interface 1 is provided with a recessed portion, which is annular, and a sealing layer 2 is provided between the recessed portion and the inner wall surface of the straight pipe 3. The outer diameter of the recessed portion is smaller than that of the pipe interface 1. The pipe interface 1 and the straight pipe 3 can be connected by bolts, threads, snaps, etc. The sealing layer 2 can be a rubber ring, sealing filler, or other structures to form a seal at the rear end connection of the straight pipe 3.

[0027] Furthermore, the plug 6 has a plug portion at its rear end, which is inserted into the blind hole of the connector 10. The rear end of the connector 10 abuts against the front end of the spring 4, and the front end of the connector 10 abuts against the inner protrusion.

[0028] The plug 6 and the connector 10 abut against each other, forming a component that moves together. The design of the plug 6 and the connector 10 facilitates their installation and removal.

[0029] Furthermore, a limiting protrusion 601 is provided on the annular surface of the plug 6, the limiting protrusion 601 abuts against the rear end of the adjusting sleeve 9, and the adjusting sleeve 9 is threadedly connected to the front end of the straight pipe 3.

[0030] Furthermore, the rear end of the adjusting sleeve 9 is provided with an annular inner protrusion 901, which abuts against the limiting protrusion 601.

[0031] Both the limiting protrusion 601 and the annular inner protrusion 901 are annular, and the sleeve 9 has a hollow structure. By rotating the sleeve 9, the plug 6 can be moved through the cooperation of the limiting protrusion 601 and the annular inner protrusion 901. When the straight pipe 3 needs to drain water separately, it can be done by rotating the sleeve 9. After draining water, the sleeve 9 needs to be rotated to reset.

[0032] Furthermore, the front end of the pin body 8 is provided with an annular connecting groove 801, and a pin head 802 is formed in the annular connecting groove 801. The pin head 802 is used to abut against the end of the plug 6.

[0033] The annular connecting groove 801 is adapted to the front end of the straight tube 3. When the pin body 8 is inserted into the straight tube 3, the front end of the straight tube 3 is inserted into the annular connecting groove 801.

[0034] Furthermore, the adjusting sleeve 9 is located inside the straight tube 3. When the pin body 8 is inserted into the straight tube 3, the front end of the adjusting sleeve 9 is inserted into the annular connecting groove 801.

[0035] When the pin body 8 is inserted into the straight tube 3, the front ends of the adjusting sleeve 9 and the straight tube 3 are both located in the annular connecting groove 801 to form a sealing structure.

[0036] Furthermore, an O-ring 7 is provided on the outer wall surface of the pin head 802; the O-ring 7 is used to cooperate with the inner side of the adjusting sleeve 9, which further improves the sealing performance of this utility model.

[0037] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model.
