Description

Technical Field

[0001] This application relates to the field of radio frequency coaxial relay technology, and more specifically, to a sealed structure and a radio frequency coaxial relay. Background Technology

[0002] Existing radio frequency coaxial relays mainly rely on applying sealant for sealing. However, the sealant layer is prone to peeling off after long-term corrosion, thus affecting the sealing effect. Some systems also use sealing gaskets for protection, such as the sealing structure of a radio frequency coaxial relay disclosed in application number CN202410793943.8. This structure includes a housing and a cavity. The cavity includes a base and a radio frequency connector connected to the base. The base is disposed within the cavity, and an annular sealing groove is formed on the outer wall of the base. A sealing ring is fitted into the annular sealing groove, with a portion of the sealing ring extending out of the annular sealing groove and in close contact with the inner wall of the housing.

[0003] The aforementioned RF coaxial relay uses only a single-structure sealing ring for sealing. Although it has better anti-corrosion effect compared to glue sealing, the simple structure of the sealing ring results in poor wrapping effect on the RF connector, which makes it easy for gaps to appear between the outer periphery of the RF connector and the internal core, thereby reducing the sealing and protection effect on the internal core. Utility Model Content

[0004] To overcome the above deficiencies, this application provides a sealing structure and a radio frequency coaxial relay, aiming to improve the problem in the related technology where the sealing ring structure is simple, the wrapping effect on the radio frequency connector is poor, and gaps easily appear in the area between the radio frequency connector and the internal core, thereby reducing the sealing and protection effect on the internal core.

[0005] This application provides a sealing structure, including a housing assembly and a sealing assembly.

[0010] In one specific implementation, the upper surface of the lower sealing gasket is provided with a groove, and the lower surface of the upper sealing gasket is provided with a protrusion that engages with the groove.

[0011] In one specific implementation, the outer corner of the bottom of the protrusion and the bottom corner of the inner side of the slot are both rounded.

[0012] In one specific implementation, a seat block is provided on the side of the outer shell, and an ear plate that cooperates with the seat block is provided on the side of the shell cover.

[0018] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0019] Please see Figures 1-8 This application provides a sealing structure, including a housing assembly 1 and a sealing assembly 2.

[0020] The housing assembly 1 includes an outer shell 11 and a cover 12. The outer shell 11 and the cover 12 are detachably fixed, and the surface of the cover 12 is provided with a mounting port I 17. The sealing assembly 2 includes a sealing gasket 21 and an inner retaining ring 24. The sealing gasket 21 is provided with a mounting port II 23, and the inner retaining ring 24 is provided inside the sealing gasket 21. The inner retaining ring 24 is installed inside the inner retaining ring 24 and is coaxially arranged with the mounting port II 23. The inner retaining ring 24 is provided with a break 22. The upper inner edge of the outer shell 11 is provided with a lower sealing groove 15 that mates with the sealing gasket 21, and the bottom of the cover 12 is provided with an upper sealing groove 16 that mates with the sealing gasket 21.

[0021] The cover 12 and the outer shell 11 are fixed together with bolts. The sealing gasket 21 between the outer shell 11 and the cover 12 is tightly fixed for sealing through the cooperation of the lower sealing groove 15 and the upper sealing groove 16. The mounting port I 17 on the cover 12 and the mounting port II 23 on the sealing gasket 21 are used to pass through the mounting joint. The inner retaining ring 24 is engaged with the outer periphery of the mounting port II 23, so that the inner wall of the mounting port II 23 is tightly fitted with the outer periphery of the joint. The break 22 provided on the inner retaining ring 24 gives the inner retaining ring 24 better locking force, so that the outer wall of the mounting port II 23 can be sealed and fitted with the outer periphery of the joint for a long time, resulting in better sealing effect.

[0022] In a specific configuration, the sealing assembly 2 also includes a gasket 26, which is disposed inside the cavity 25. The gasket 26 enhances the strength of the cavity 25 when it is compressed and reduces the deformation of the sealing gasket 21 when it is compressed.

[0023] Furthermore, the sealing assembly 2 also includes a sealing ring 27, which is disposed at the bottom of the sealing gasket 21. The sealing ring 27 and the bottom of the sealing gasket 21 form a right angle and engage with the bottom corner of the lower sealing groove 15. The sealing ring 27 increases the contact area with the inner wall of the housing 11, further improving the sealing effect of the sealing gasket 21.

[0024] In the above specific embodiment, the sealing gasket layer 21 includes a lower sealing gasket 211 and an upper sealing gasket 212, which are detachably disposed from each other. The upper surface of the lower sealing gasket 211 is provided with a groove 29, and the lower surface of the upper sealing gasket 212 is provided with a protrusion 28 that engages with the groove 29.

[0025] In one specific implementation, the outer corners of the bottom of the protrusion 28 and the inner bottom corners of the groove 29 are both rounded. The sealing gasket layer 21 serves as a removable lower sealing gasket 211 and upper sealing gasket 212, facilitating the installation of the inner retaining ring 24 and reducing costs for mass production. The protrusion 28 and the groove 29 ensure a tighter engagement between the lower sealing gasket 211 and the upper sealing gasket 212. The inner retaining ring 24 can be made of plastic or a metal ring with good toughness.

[0026] Specifically, a seat block 13 is provided on the side of the outer casing 11, and an ear plate 14 that mates with the seat block 13 is provided on the side of the casing cover 12. Both the seat block 13 and the ear plate 14 are provided with mounting holes for bolt engagement, allowing the outer casing 11 and casing cover 12 to be disassembled and assembled using bolt engagement.

[0027] This application also provides a radio frequency coaxial relay, including the sealing structure described above and a relay body assembly 3.

The battery module 31 is disposed inside the housing 11, and the radio frequency connector 32 is installed on the outside of the battery module 31, penetrating through mounting port I 17 and mounting port II 23. That is, the smooth outer ring of the radio frequency connector 32 contacts the inner wall of mounting port II 23 in the sealing gasket layer 21 to achieve a seal.

[0028] It should be noted that the specific model and specifications of the battery module 31 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0029] The sealing structure and the working principle of the RF coaxial relay are as follows: During use, the cover 12 and the outer shell 11 are fixed together with bolts. The sealing gasket 21 between the outer shell 11 and the cover 12 is tightly fixed for sealing through the cooperation of the lower sealing groove 15 and the upper sealing groove 16. The mounting port I 17 on the cover 12 and the mounting port II 23 on the sealing gasket 21 are used to pass through the mounting connector. The inner retaining ring 24 is engaged with the outer periphery of the mounting port II 23, so that the inner wall of the mounting port II 23 is tightly fitted with the outer periphery of the connector. The break 22 provided on the inner retaining ring 24 gives the inner retaining ring 24 better locking force, so that the outer wall of the mounting port II 23 can be sealed and fitted with the outer periphery of the connector for a long time, resulting in a better sealing effect.
