[0002] In electrical cabinet cooling systems, the connection of the liquid circuit is crucial, requiring connectors to link rigid pipes and flexible hoses. Traditionally, flexible hose connectors and rigid pipe connectors are assembled together using threaded connections. This separate structure has several drawbacks: firstly, the assembly process is cumbersome, increasing manual labor costs and time, and threaded connections are prone to loosening, affecting connection reliability; secondly, the separate structure is weak in positioning, installation, and sealing / dustproofing, making it difficult to meet the stringent stability and sealing requirements of electrical cabinet cooling systems. Therefore, there is an urgent need for an integrated, more functional connector to solve these problems. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example 1

[0025] like Figure 1 , Figure 2 As shown, a specific embodiment of the integrated positioning and sealing joint of this utility model includes:

[0026] Rigid pipe connection end 1: Used to connect rigid pipes in liquid circuits. The outer surface of rigid pipe connection end 1 is provided with external threads, and the inner cavity is a tapered sleeve 2. In actual use, rigid pipe connection end 1 is connected to a compression sleeve steel pipe (not shown in the figure) with a nut. The tapered sleeve 2 is sleeved with the compression sleeve steel pipe, and the external threads are connected and fixed with the nut. By utilizing the structural characteristics of the tapered sleeve 2 and cooperating with the nut, a quick and stable connection of the rigid pipe can be achieved, ensuring the sealing of liquid transmission.

[0027] The connector body 3: The rigid pipe connection end 1 is fixedly installed on the left side of the connector body 3. The connector body 3 is designed in the shape of a hexagonal nut, which makes it easy for operators to rotate and disassemble with tools, thus improving the convenience of installation and maintenance. A sealing groove 4 is provided on the right end face of the connector body 3. A sealing ring 5 is installed in the sealing groove 4. The sealing ring 5 is used for sealing and dust prevention, which can effectively prevent external dust and impurities from entering the connector connection part, improve the connection stability, and extend the service life.

[0028] Positioning threaded post 7: used to be inserted into the mounting hole on the main board (not shown in the figure). It is fixedly set on the right side of the connector body 3, and plays the role of positioning and initially fixing the connector, laying the foundation for subsequent tightening by flat nut 6.

[0029] Flat nut 6: Its threads are installed on the positioning threaded post 7. After the positioning threaded post 7 is inserted into the main board mounting hole, the connector can be firmly fixed on the main board by tightening the flat nut 6, ensuring that the connector is stable in position during use and avoiding displacement due to vibration or other factors.

[0030] Hose connection end 8: It is used to connect the hose in the liquid circuit. The hose connection end 8 is fixedly installed on the right side of the positioning threaded post 7. An annular limiting protrusion 9 is fixedly provided on the hose connection end 8. There are two limiting protrusions 9. The two limiting protrusions 9 can better limit the hose, prevent the hose from falling off during use, and improve the reliability of the hose connection.

[0031] Example 2

[0032] like Figure 3As shown, the difference between this embodiment and Embodiment 1 is that an annular boss 10 is provided between the connector body 3 and the positioning threaded post 7. The annular boss 10 is used to fit into the mounting hole on the motherboard, further improving the stability of the connector and motherboard installation. The right end face edge of the annular boss 10 is provided with a slanted assembly surface 11, which is used to facilitate quick insertion into the motherboard mounting hole during assembly and reduce assembly difficulty. A dividing slit 12 is provided laterally on the annular boss 10. The dividing slit 12 can compensate for deformation such as thermal expansion and contraction during use, ensuring connection stability and sealing. Three dividing slits 12 are set at equal intervals around the annular boss 10.

[0033] The working principle of this utility model:

[0034] Rigid pipe connection: Select a suitable ferrule steel pipe with a nut, insert the ferrule steel pipe into the tapered sleeve 2 of the rigid pipe connection end 1, so that the ferrule steel pipe and the tapered sleeve 2 fit tightly, and then screw the nut onto the external thread of the rigid pipe connection end 1 and tighten the nut. By using the cooperation between the nut and the external thread, as well as the constraint of the tapered sleeve 2 on the ferrule steel pipe, a stable connection of the rigid pipe can be achieved.

[0035] Motherboard Installation: Align the positioning threaded post 7 of the connector with the mounting hole on the motherboard. Using the inclined mounting surface 11 on the right end face of the annular boss 10, insert the annular boss 10 into the mounting hole. At this point, the positioning threaded post 7 is inserted into the mounting hole, and the annular boss 10 and the mounting hole are fitted together. Next, screw the flat nut 6 onto the positioning threaded post 7 and gradually tighten the flat nut 6 so that the connector body 3 is tightly fitted with the motherboard mounting hole through the annular boss 10 until the connector is firmly fixed to the motherboard. During the assembly process, the dividing slot 12 of the annular boss 10 allows it to undergo moderate elastic deformation, better adapting to the mounting hole and ensuring installation stability.

[0036] Hose connection: Select a suitable hose, put the hose on the hose connection end 8, and use the two annular limiting protrusions 9 to limit the hose and prevent it from falling off, thus completing the hose connection.

[0037] All components mentioned in this article are general standard parts or components known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods, so they will not be described in detail here.

[0038] While the specific embodiments of this utility model have been described in detail above, this utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this utility model. Modifications or variations that do not involve creative labor are still within the protection scope of this utility model.
