Description

Technical Field

[0001] This utility model relates to the field of electromagnetic shielding technology, specifically to an anti-electromagnetic interference remote sensing image data transmission antenna cover device. Background Technology

[0002] A shielding cover is a tool used to shield electronic signals. Its function is to shield the influence of external electromagnetic waves on internal circuits and to prevent the radiation of electromagnetic waves generated internally outwards.

[0003] In the prior art, Chinese utility model publication CN222107014U discloses an antenna radome capable of shielding electromagnetic signals from the back, comprising a radome body and a base. A protective edge is integrally connected to the bottom of the radome body, and an electromagnetic shielding structure is provided inside the radome body. This electromagnetic shielding structure includes a first electromagnetic shielding cover and a second electromagnetic shielding cover. The first electromagnetic shielding cover is attached to the inner wall of the radome body, and the second electromagnetic shielding cover is attached to the inner wall of the first electromagnetic shielding cover. A sleeve is fixedly connected to the top of the first electromagnetic shielding cover, penetrating the radome body. A first turntable is fixedly installed on the outside of the sleeve, and a rotating rod is fixedly installed on the top of the second electromagnetic shielding cover. This utility model's antenna radome capable of shielding electromagnetic signals from the back can provide electromagnetic shielding for the antenna, preventing interference from external magnetic fields. Furthermore, the first and second electromagnetic shielding covers can be rotated and misaligned via the first and second turntables, allowing adjustment of the electromagnetic shielding range as needed.

[0004] The above technical solution mainly relies on the first electromagnetic shielding cover and the second electromagnetic shielding cover for electromagnetic shielding protection. However, the bottom of both the first electromagnetic shielding cover and the second electromagnetic shielding cover is an open design, which results in insufficient shielding range.

[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. 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.

[0024] This utility model provides, for example Figures 1-5 The electromagnetic interference-resistant remote sensing image data transmission radome device shown includes:

[0025] Antenna radome body;

[0026] The antenna radome body includes a top cover 1, a U-shaped frame 2 and a base plate 3. The top cover 1 is provided with a top metal shielding mesh 4, the base plate 3 is provided with a bottom metal shielding mesh 5, and the U-shaped frame 2 is provided with a U-shaped metal shielding mesh 6 that connects the top metal shielding mesh 4 and the bottom metal shielding mesh 5. The U-shaped frame 2 and the bottom plate are installed on both sides of the circuit board 19.

[0027] By disassembling the radome body into a top cover 1, a U-shaped frame 2, and a base plate 3, with the U-shaped frame 2 and the base plate 3 located on both sides of the circuit board 19, and then connecting the top metal shielding mesh 4, the U-shaped metal shielding mesh 6, and the bottom metal shielding mesh 5 inside the top cover 1, the U-shaped frame 2, and the base plate 3, an all-round metal shielding cover is formed to provide electromagnetic shielding protection for the circuits in the circuit board 19. At the same time, the radome body is also very convenient to disassemble and assemble.

[0028] Among them, such as Figure 3-5 As shown:

[0029] The top metal shielding mesh 4, the bottom metal shielding mesh 5, and the loop-shaped metal shielding mesh 6 all include a mesh body 7. One end of the mesh body 7 in the top metal shielding mesh 4 and the bottom metal shielding mesh 5 is provided with multiple sets of first guide posts 8. Both ends of the mesh body 7 in the loop-shaped metal shielding mesh 6 are provided with second guide posts 9 that are aligned with the first guide posts 8. The end of the first guide post 8 is provided with a groove 10, and the end of the second guide post 9 is inserted into the groove 10. By setting the structure of the top metal shielding mesh 4, the loop-shaped metal shielding mesh 6, and the bottom metal shielding mesh 5, it is convenient to ensure that the top metal shielding mesh 4, the loop-shaped metal shielding mesh 6, and the bottom metal shielding mesh 5 can be stably connected to form a mesh shielding cover when connecting the top cover 1, the loop-shaped frame 2, and the base plate 3.

[0030] Furthermore, such as Figure 2 , Figure 4 and Figure 5 As shown:

[0031] The top cover 1 has a fastener 11 integrally formed around its bottom. The upper end of the side wall of the U-shaped frame 2 has a slot 12 that engages with the fastener 11. The fastener 11 and the slot 12 work together to easily connect the top cover 1 to the U-shaped frame 2. The circuit board 19 can be maintained without removing most of the structure of the antenna cover.

[0032] Preferred, such as Figure 2 As shown:

[0033] The top four corners of the U-shaped frame 2 are provided with countersunk holes 13, and mounting screws 14 are movably installed in the countersunk holes 13. The circuit board 19 is provided with through holes 15 for the second guide post 9 and the mounting screws 14 to pass through. The base plate 3 is provided with threaded holes 16 that cooperate with the mounting screws 14. By cooperating with the mounting screws 14 and the threaded holes 16, the U-shaped frame 2 and the base plate 3 can be easily installed on both sides of the circuit board 19.

[0034] It is worth noting that, such as Figure 2 and Figure 4 As shown:

[0035] The bottom of the herringbone frame 2 is fixed with positioning posts 17 around its perimeter. The circuit board 19 has positioning grooves 18 that cooperate with the positioning posts 17. The cooperation between the positioning posts 17 and the positioning grooves 18 facilitates the positioning of the herringbone frame 2 and prevents the herringbone frame 2 from sliding on the circuit board 19, which would cause the second guide post 9 to bend and make it difficult to connect with the first guide post 8.

[0036] In a further preferred embodiment, such as Figure 4 As shown:

[0037] The four corners of the mesh body 7 in the U-shaped metal shielding mesh 6 are provided with collapsed areas. The collapsed areas are located outside the countersunk holes 13. The outer sides of the top metal shielding mesh 4, the bottom metal shielding mesh 5, and the U-shaped metal shielding mesh 6 are all wrapped with an insulating protective layer. The design of the collapsed areas facilitates the misalignment of the countersunk holes 13 so as not to affect the use of the mounting screws 14. At the same time, the design of the insulating protective layer facilitates the isolation of the top metal shielding mesh 4, the U-shaped metal shielding mesh 6, and the bottom metal shielding mesh 5 from the top cover 1, the U-shaped frame 2, and the base plate 3, so as to realize two independent electromagnetic shielding systems.

[0038] In practical use, the loop frame 2 is placed on one side of the circuit board 19, and the loop frame 2 is limited by the positioning post 17 and the positioning groove 18. Then, the mounting screw 14 is placed in the countersunk hole 13, and the base plate 3 is placed on the other side of the circuit board 19. The mounting screw 14 is aligned with the threaded hole 16 on the base plate 3, and the loop frame 2 and the base plate 3 are installed on both sides of the circuit board 19. Then, the top cover 1 is placed on top of the loop frame 2, and the top cover 1 and the loop frame 2 are snapped and fixed by the fastener 11 and the slot 12. During this period, the first guide post 8 and the second guide post 9 are connected to connect the top metal shielding mesh 4, the loop metal shielding mesh 6 and the bottom metal shielding mesh 5, so as to provide electromagnetic shielding protection for the circuit in the circuit board 19 in all directions.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
