[0039] Figure 1 This is a schematic diagram of the phase shifter assembly provided in an embodiment of the present invention. Figure 2 This is a schematic diagram of a partial structure of the phase shifter assembly provided in an embodiment of the present invention. Figure 3 This is an exploded view of a portion of the structure of the phase shifter assembly provided in this embodiment of the present invention, combined with... Figures 1 to 3 As shown, the phase shifter assembly includes a first circuit board 1, a second circuit board 2, a first limiting structure 3, and a second limiting structure 4. It should be noted that... Figure 4 This is a schematic diagram of the first circuit board provided in an embodiment of the present invention, as shown below. Figure 4 As shown, the first circuit board 1 has a first strip 11. Correspondingly, Figure 5 This is a schematic diagram of the second circuit board provided in an embodiment of the present invention, as shown below. Figure 5As shown, the second circuit board 2 has a second stripline 21. It should be noted that both the first circuit board 1 and the second circuit board 2 are single-sided networks. It is easily understood that the second circuit board 2 is placed on the first circuit board 1, and the second stripline 21 is located on the side facing the first circuit board 1 for contact electrical connection with the first stripline 11. Further, the first limiting structure 3 is fixed to the first circuit board 1 and presses the second circuit board 2 towards the first circuit board 1, thereby allowing the second circuit board 2 to be movably clamped between the first limiting structure 3 and the first circuit board 1, while also helping to ensure stable contact electrical connection between the first stripline 11 and the second stripline 21. Further still, the second limiting structure 4 is fixed to the second circuit board 2 and is configured to push the second circuit board 2 relative to the first circuit board 1, thereby allowing the second stripline 21 to contact electrical connection with different positions of the first stripline 11 for phase shifting. Thus, the phase shifter assembly achieves a simplified structure through the cooperation of the first limiting structure 3 and the second limiting structure 4, which helps to improve assembly efficiency and reduce material costs, while also enabling high-precision phase control to improve antenna performance consistency.

[0040] Combination Figures 1 to 3 As shown, in one embodiment, the first limiting structure 3 includes a first main body 31, and the first main body 31 is located on the second circuit board 2. Specifically, Figure 6 This is a schematic diagram of the first main component provided in an embodiment of the present utility model. Figure 7 This is a schematic diagram of the first main body provided in an embodiment of the present utility model from another perspective, combined with... Figure 6 and Figure 7 As shown, the first main body 31 is provided with a first buckle 311. It should be noted that the first buckle 311 is configured as a hook-shaped structure, and its number and position can be set as needed. For example, six first buckles 311 are provided and symmetrically distributed on both sides of the first main body 31. Further, the first buckles 311 are fastened to the side of the first circuit board 1 facing away from the second circuit board 2, thereby clamping the second circuit board 2 between the first circuit board 1 and the first main body 31. Thus, when the second circuit board 2 moves relative to the first circuit board 1, the first main body 31 can prevent the second circuit board 2 from losing contact with the first circuit board 1, thereby avoiding loose connections and ensuring the reliability of the electrical connection.

[0041] Combination Figure 6 and Figure 7As shown, in one embodiment, the first main body 31 is further provided with an elastic pressure plate 312. It should be noted that the elastic pressure plate 312 presses the second circuit board 2 towards the first circuit board 1, thereby further ensuring that the second circuit board 2 does not lose contact with the first circuit board 1, thus improving the reliability of the electrical connection. That is, while the first main body 31 clamps the second circuit board 2 and the first circuit board 1 through the first buckle 311, the elastic pressure plate 312 can apply greater pressure to the second circuit board 2 using its own elasticity, thereby making the contact between the second circuit board 2 and the first circuit board 1 tighter.

[0042] Combination Figure 6 and Figure 7 As shown, in one embodiment, the first main body 31 has a perforation 315, and an elastic pressure plate 312 is disposed within the perforation 315 to press the second circuit board 2. It is readily understood that the number of perforations 315 is the same as the number of elastic pressure plates 312. Furthermore, the perforations 315 are located inside the first latch 311, thereby ensuring that the elastic pressure plate 312 is located inside the first latch 311, thus ensuring that the elastic pressure plate 312 can accurately press against the second circuit board 20.

[0043] Combination Figures 1 to 3 As shown, in one embodiment, the first limiting structure 3 further includes a rivet 32 ​​and an elastic clip 33. Specifically, the rivet 32 ​​fixes the first main body 31 and the first circuit board 1, thereby clamping the second circuit board 2 between the first main body 31 and the first circuit board 1. Further, the elastic clip 33 is located on the side of the first circuit board 1 facing away from the second circuit board 2. By clamping the rivet 32, it achieves the purpose of fixing the first main body 31 and the first circuit board 1 with the rivet 32, thereby ensuring that the second circuit board 2 can be in close contact with the first circuit board 1. Exemplarily, the rivet 32 ​​passes through the first main body 31, the second circuit board 2, and the first circuit board 1 in sequence, and the end of the rivet 32 ​​is fixed by the elastic clip 33. The elastic clip 33 applies force to the rivet 32 ​​using its own elasticity while abutting against the first circuit board 1, thereby enhancing the fastening effect of the rivet 32 ​​on the first main body 31 and the first circuit board 1, and further clamping the second circuit board 2 between the first main body 31 and the first circuit board 1, that is, making the contact between the second circuit board 2 and the first circuit board 1 tighter.

[0044] like Figure 5 As shown, in one embodiment, the second circuit board 2 is provided with a guide groove 22. Further, as... Figure 7As shown, a guide block 313 extends toward the first circuit board 1. Further, a rivet 32 ​​passes through the guide block 313. It is readily understood that the guide block 313 is movably located within the guide groove 22, and moves relative to the guide groove 22 when the second circuit board 2 moves relative to the first circuit board 1. That is, the guide block 313, in conjunction with the guide groove 22, can limit the linear movement direction of the second circuit board 2, thereby ensuring the reliability of the electrical connection between the first circuit board 1 and the second circuit board 2.

[0045] Figure 8 This is a schematic diagram of the rivet provided in an embodiment of the present invention, as shown below. Figure 8 As shown, in one embodiment, the rivet 32 ​​includes a rod 321 and a cap 322. Specifically, the rod 321 is cylindrical and has an annular groove 3211 at its first end, which engages with an elastic clamping piece 33. On the other hand, the cap 322 is located at the second end of the rod 321, and the cross-sectional dimension of the cap 322 is larger than that of the rod 321. Thus, corresponding to a circular cross-section, the diameter of the cap 322 is larger than the diameter of the rod 321. The cap 322 can abut against the first main body 31, while the rod 321 is clamped by the elastic clamping piece 33 and subjected to force, thereby achieving a clamping effect.

[0046] Figure 9 This is a schematic diagram of the elastic compression sheet provided in an embodiment of the present invention, as shown below. Figure 9 As shown, in one embodiment, the elastic clip 33 is configured with a dome-shaped structure and has a through hole 331 at its center. Further, the elastic clip 33 also has a plurality of slits 332, and the slits 332 are arranged around the through hole 331. Even further, as... Figure 8 As shown, the end face of the first end of the rod 321 is spherical, and a portion of it protrudes to form a connecting portion 3212. It is readily understood that the connecting portion 3212 and the slot 332 are matched and connected so that the rod 321 passes through the through hole 331, allowing the elastic clip 33 to be clamped within the annular groove 3211. It should be noted that the elastic clip 33 arches away from the top cap 322, thereby applying force to the rivet 32. It should be noted that in this embodiment, there are four slots 332 arranged in a cross shape, and the connecting portion 3212 is correspondingly formed in a cross structure. Optionally, there may be two, three, five, or more slots 332, and the shape of the connecting portion 3212 is set according to the number and arrangement of the slots 332.

[0047] like Figure 6As shown, in one embodiment, the first main body 31 is provided with a receiving groove 314 for accommodating the top cap 322. It is easy to understand that the receiving groove 314 matches the outer dimensions of the top cap 322. Thus, the top cap 322 can be prevented from protruding and occupying space, and it can also play a positioning role for the rivet 32.

[0048] Combination Figure 6 and Figure 7 As shown, in one embodiment, the bottom of the receiving groove 314 is provided with a first positioning hole 316 that penetrates the guide block 313. Correspondingly, as... Figure 4 As shown, the first circuit board 1 is provided with a second positioning hole 14. Thus, when the rivet 32 ​​is installed, the top cap 322 of the rivet 32 ​​is placed in the receiving groove 314, and the shank 321 of the rivet 32 ​​passes through the first positioning hole 316, the guide groove 22, the second positioning hole 14 and the through hole 331 in sequence, so that the rivet 32 ​​can cooperate with the elastic clip 33 to achieve a clamping effect without affecting the movement of the second circuit board 2.

[0049] like Figure 4 As shown, in one embodiment, the first circuit board 1 is provided with a clearance groove 12. Specifically, the first latch 311 passes through the clearance groove 12, thereby enabling it to be fastened to the side of the first circuit board 1 opposite to the second circuit board 2. It should be noted that the position of the clearance groove 12 matches the size of the second circuit board 2, so that the first latch 311 can abut against the edge of the second circuit board 2 while fastening the first circuit board 1, thereby preventing the second circuit board 2 from deviating from the predetermined path when moving.

[0050] Combination Figures 1 to 3 As shown, in one embodiment, the second limiting structure 4 includes a second main body 41, and the second main body 41 is located on the second circuit board 2. Further, Figure 10 This is a schematic diagram of the second main body component provided in an embodiment of the present utility model. Figure 11 This is a schematic diagram of the second main body provided in an embodiment of the present utility model from another perspective, combined with... Figure 10 and Figure 11 As shown, the second main body 41 is provided with a second latch 411. Specifically, the second latch 411 is fastened to the side of the second circuit board 2 facing the first circuit board 1. It should be noted that the number and position of the second latches 411 can be adjusted as needed. Thus, by setting the second latches 411, the second main body 41 can limit the movement of the second circuit board 2 and at the same time help drive the second circuit board 2 to move.

[0051] like Figure 4As shown, in one embodiment, the first circuit board 1 is provided with a limiting groove 13 to accommodate the second latch 411. It is readily understood that the shape and size of the limiting groove 13 are adapted to the movement path of the second latch 411 and also help guide the movement of the second circuit board 2.

[0052] like Figure 11 As shown, in one embodiment, the second main body 41 extends toward the first circuit board 1 and is formed with mounting posts 412. Further, as... Figure 5 As shown, the second circuit board 2 is provided with mounting holes 23. It is easy to understand that the mounting holes 23 are matched with the mounting posts 412. Thus, the second main body 41 can be fixedly assembled with the second circuit board 2 through the mounting posts 412, and the mounting posts 412 can also apply force to the second circuit board 2 to drive the second circuit board 2 to move.

[0053] like Figure 1 As shown, in one embodiment, the phase shifter assembly further includes a drive mechanism 5. Specifically, the drive mechanism 5 is connected to the second limiting structure 4, thereby pushing the second circuit board 2 relative to the first circuit board 1 through the second limiting structure 4. More specifically, the drive mechanism 5 includes a motor 51, a transmission member 52, and a connecting member 53. Further, as... Figure 10 As shown, the second main body 41 of the second limiting structure 4 is provided with a connecting post 413. Furthermore, the connecting member 53 is connected to the connecting post 413, and the transmission member 52 is connected to the motor 51 and the connecting member 53 respectively. Thus, the drive mechanism 5 can drive the second circuit board 2 to move. It should be noted that the transmission member 52 in this embodiment is a ball screw, which can ensure motion accuracy, thereby achieving high-precision phase control and improving antenna performance consistency.

[0054] This utility model provides a phase shifter assembly, including a first circuit board, a second circuit board, a first limiting structure, and a second limiting structure. The first circuit board has a first stripline, and the second circuit board is placed on the first circuit board with a second stripline on its side facing the first circuit board. The second stripline is electrically connected to the first stripline. The first limiting structure is fixed to the first circuit board and presses the second circuit board towards the first circuit board, clamping the second circuit board between the first limiting structure and the first circuit board. The second limiting structure is fixed to the second circuit board and pushes the second circuit board relative to the first circuit board, causing the second stripline to make electrical connections with the first stripline at different positions, thus performing phase shifting. Therefore, the phase shifter assembly achieves a simplified structure, helps improve assembly efficiency and reduce material costs, while enabling high-precision phase control to improve antenna performance consistency.

[0055] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art.
