Description

Technical Field

[0001] The utility model relates to the technical field of antenna equipment, in particular to a phase shifter cavity structure. Background Art

[0002] The phase shifter of the base station antenna is the core component of the electrically adjustable antenna, which is used to adjust the phase of the base station antenna. The structure of the phase shifter usually includes a cavity, a phase shifting circuit board, a dielectric block, a connecting rod, and a transmission rod. Usually, the transmission rod extends from the openings at both ends of the cavity and is connected to the external drive rod to achieve the sliding of the dielectric block inside the phase shifter relative to the circuit board. This is also because the transmission rod of the entire cavity phase shifter needs to extend from the end. This method occupies a large amount of space in the length direction, which causes certain difficulties and restrictions on the layout of the entire base station antenna. It is necessary to further improve the flexibility of the transmission connection;

[0003] Therefore, it is necessary to design a phase shifter cavity structure to further reduce the space occupied by the layout and improve the installation flexibility. Summary of the invention

[0006] (II) Technical solution

[0007] To achieve the above objectives, the utility model is implemented through the following technical solutions: a phase shifter cavity structure, including a transmission connecting piece, a connecting rod, a cavity and a driving rod, the connecting rod is movably installed on the top of the inner side of the cavity, a slide groove is opened on the top of the cavity, the transmission connecting piece is movably installed inside the slide groove, and a limiting guide rail is set at the bottom of the cavity.

[0008] Preferably, two insert blocks are provided at the bottom of the transmission connection member, two slots are provided at the top of the connecting rod, and the two insert blocks correspond to the two slots.

[0011] (III) Beneficial effects

[0012] The utility model provides a phase shifter cavity structure. It has the following beneficial effects: the phase shifter cavity structure, the cavity bottom adds a limit guide rail of the transmission member, and then adds a slot at the bottom of the phase shifter, which can be quickly connected to the internal connecting rod with a specially designed transmission adapter. By opening a slide groove at the top of the cavity, the transmission connecting member is movably installed inside the slide groove, and then can be quickly connected to the internal connecting rod. When the driving rod drives the transmission adapter to move, the plug at its bottom drives the internal connecting rod to move. The connecting rod cooperates with the slider, thereby driving the slider to slide on the surface of the PCB circuit, thereby changing the phase amplitude of the circuit and realizing the function of changing the antenna radiation downtilt angle. There are multiple connecting rod grooves inside the phase shifter to choose from, which greatly compresses the space occupied by the length direction of the phase shifter. The external driving rod can also be installed in both horizontal and vertical directions, and the installation position can have multiple options according to the position of the phase shifter connecting rod, which greatly improves the freedom of layout of the base station antenna.
