[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1 Please see Figure 1-4 As shown, a modular and configurable radio frequency module includes a housing 1, and a cover 2 is provided on the top of the housing 1; The housing 1 has an installation groove 5 inside, the upper surface of the installation groove 5 extends to the outside of the housing 1, the installation groove 5 is provided with an RF module body 3, the connecting parts on the front and rear surfaces of the RF module body 3 extend to the outside of the housing 1 and the cover 2, and an installation assembly is provided between the housing 1 and the cover 2. The mounting assembly includes four slots 6 located on the left and right sides, front and rear of the top of the housing 1, respectively. Insert plates 7 are inserted into the slots 6, with their tops fixedly connected to the bottom of the housing cover 2. A snap-fit ​​assembly is provided between the insert plates 7 and the slots 6. During operation, when the housing cover 2 needs to be assembled with the housing 1, the insert plates 7 fixedly connected to the bottom of the housing cover 2 are inserted into the slots 6 on the top of the housing 1. During insertion, the snap-fit ​​assembly securely mounts the housing cover 2 and the housing 1, ensuring stable installation and facilitating subsequent disassembly. This allows for easy disassembly, inspection, and maintenance of the RF module body 3 in the mounting slot 5 inside the housing 1. Furthermore, after the RF module body 3 is installed between the housing 1 and the housing cover 2, the connecting parts on both the front and rear surfaces of the RF module body 3 extend to the outside, facilitating configuration and installation with external devices during subsequent use.

[0020] The substrate of the RF module body 3 has multiple evenly distributed and through-holes 12. The lower surface of the mounting groove 5 is fixedly connected to the corresponding position of the through-holes 12, and the top of the through-hole 11 passes through the through-hole 12. During operation, when the RF module body 3 is placed inside the mounting groove 5, the through-hole 11 fixedly connected to the lower surface of the mounting groove 5 will be inserted into the through-hole 12 inside the substrate of the RF module body 3. Through the cooperation of the through-hole 12 and the through-hole 11, the RF module body 3 can be initially positioned and fixed, preventing the RF module body 3 from shaking inside the mounting groove 5 and ensuring the stability of the RF module body 3 installation.

[0021] A limiting rod 10 is fixedly connected to the lower inner surface of the cover 2, corresponding to the insertion rod 11. The limiting rod 10 has an opening at its bottom, and the top end of the insertion rod 11 is inserted into the opening. The bottom end of the limiting rod 10 is in contact with the top of the RF module body 3. During operation, when the cover 2 is assembled with the housing 1, the limiting rod 10 fixedly connected to the lower inner surface of the cover 2 will gradually approach the RF module body 3 as the cover 2 moves downward, until the opening at the bottom of the limiting rod 10 fits over the top end of the insertion rod 11, and the bottom end of the limiting rod 10 is in contact with the top of the RF module body 3. At this time, the limiting rod 10 and the insertion rod 11 cooperate with each other to limit and fix the RF module body 3 from both the top and bottom, further enhancing the stability of the RF module body 3 inside the mounting slot 5, avoiding problems such as poor contact caused by shaking of the RF module body 3 during subsequent use, and ensuring that the RF module can work normally and stably.

[0022] The snap-fit ​​assembly includes two sliding grooves 15 respectively formed on both sides of the inside of the insert plate 7. One side of the sliding groove 15 extends to the outside of the insert plate 7. A sliding ring 17 is slidably connected inside the sliding groove 15, and a fixed ring 21 is fixedly connected inside the sliding groove 15. A spring 18 is fixedly connected between the sliding ring 17 and the fixed ring 21. A connecting rod 16 slides through the fixed ring 21. One end of the connecting rod 16 passes through the spring 18 and the sliding ring 17 and is fixedly connected to the sliding ring 17. A locking block 14 is fixedly connected to one end of the connecting rod 16. Slots 13 are formed on both sides of the inside of the slot 6. The outer surface of the locking block 14 engages with the inside of the slot 13. During operation, when the insert plate 7 is inserted into the slot 6, the locking block 14 is initially positioned in the sliding groove. 15 is located near the outer side of the insert plate 7. As the insert plate 7 is inserted, the inner wall of the slot 6 will press the locking block 14. After the locking block 14 is pressed, it will drive the sliding ring 17 to slide in the slide groove 15 through the connecting rod 16. At the same time, it will compress the spring 18 between the sliding ring 17 and the fixed ring 21. When the locking block 14 moves to the position corresponding to the slot 13 opened on both sides of the slot 6, under the elastic force of the spring 18, the spring 18 will push the sliding ring 17 to slide in the opposite direction in the slide groove 15, thereby driving the connecting rod 16 and the locking block 14 to move, so that the outer surface of the locking block 14 is locked in the slot 13, realizing the fixed connection between the insert plate 7 and the slot 6, thus completing the assembly of the cover 2 and the housing 1. This locking method makes the connection and disassembly of the cover 2 and the housing 1 more convenient.

[0023] The outer surface of the locking block 14 and the inside of the locking groove 13 are both set in a semi-circular shape, and the bottom of the cover 2 is attached to the top of the housing 1. During operation, the outer surface of the locking block 14 and the inside of the locking groove 13 are both set in a semi-circular shape, so that the locking block 14 can be inserted into the locking groove 13 more smoothly, reducing the occurrence of jamming and making the assembly process smoother. At the same time, the bottom of the cover 2 is attached to the top of the housing 1, so that the cover 2 and the housing 1 can be disassembled and installed.

[0024] An inner groove 19 is formed between the two sliding grooves 15. The upper surface of the inner groove 19 extends to the outside of the housing 1. A limiting plate 8 is inserted into the inner groove 19. A through groove 22 is formed inside the housing cover 2 at a position corresponding to the inner groove 19. The top of the limiting plate 8 passes through the through groove 22 and extends to the top of the housing cover 2. A limiting bolt 4 passes through the limiting plate 8. A threaded hole 20 is formed on the lower surface of the inner groove 19. The bottom end of the limiting bolt 4 is inserted into the threaded hole 20 and threadedly connected to the threaded hole 20. During operation, after the insert plate 7 is inserted into the slot 6 and initially fixed by the snap-fit ​​assembly, in order to further enhance the stability of the connection between the housing cover 2 and the housing 1, the limiting plate 8 is inserted into the two sliding grooves 15. In the inner groove 19 between the slots 15, the top of the limiting plate 8 will pass through the corresponding through slot 22 inside the shell cover 2 and extend to the top of the shell cover 2. At this time, after the limiting bolt 4 passes through the limiting plate 8, the limiting bolt 4 is rotated so that its bottom end is inserted into the threaded hole 20 opened on the lower surface inside the inner groove 19 and is threadedly connected with the threaded hole 20. Through the cooperation of the limiting plate 8 and the limiting bolt 4, the shell cover 2 and the shell 1 can be prevented from moving relative to each other in the horizontal direction, which further ensures the stability of the connection between the shell cover 2 and the shell 1 and ensures the reliability of the entire radio frequency module structure. At the same time, the limiting of the limiting plate 8 and the limiting bolt 4 makes the locking block 14 securely engaged in the slot 13, and the locking block 14 will not disengage from the slot 13 when the shell cover 2 is moved.

[0025] A sealing frame 9 is fixedly connected to the bottom of the cover 2. The sealing frame 9 is inserted into the mounting groove 5 and is located outside the RF module body 3. During operation, after the cover 2 and the housing 1 are assembled, the sealing frame 9 fixedly connected to the bottom of the cover 2 will be accurately inserted into the mounting groove 5 opened inside the housing 1. The sealing frame 9 surrounds the outside of the RF module body 3. The sealing frame 9 is made of a material with good sealing performance, which can effectively prevent external dust, moisture and other impurities from entering the mounting groove 5, thereby protecting the RF module body 3 and avoiding the impact of impurities on the performance and service life of the RF module body 3. This ensures that the RF module can work stably and reliably in various environments. At the same time, the insertion design of the sealing frame 9 also increases the sealing between the cover 2 and the housing 1, further improving the protection level of the entire RF module.

[0026] Example 2 Please see Figure 5 As shown in the first embodiment, as another implementation of this utility model, a rectangular label slot 23 is provided at the center of the top of the cover 2.
