Abstract
Description
Technical Field
[0001] This utility model relates to the field of phase shifter technology, and in particular to a phase shifter cavity suitable for antennas. Background Technology
[0002] In communication antenna systems, the phase shifter is a core functional component for antenna beamforming, direction adjustment, and coverage optimization. Its performance directly determines the signal coverage accuracy, network capacity, and energy efficiency of the base station antenna. With the iteration of 3G / 4G / 5G networks and the development of millimeter-wave and satellite communications, the design of phase shifters is constantly evolving towards "low loss, high integration, miniaturization, and low cost," becoming one of the key aspects of antenna technology breakthroughs.
[0003] However, in practical engineering applications, multi-band phase shifters face several challenges. Multi-band systems need to adapt to multiple operating frequency bands, requiring each phase shifter to connect to multiple coaxial cables. This surge in cable quantity leads to problems such as tangling, knots, and chaotic cable arrangement during installation. On one hand, cable positioning relies on manual visual alignment, and even millimeter-level cable length deviations directly reduce the consistency of phase differences across multiple channels, resulting in beamforming shift, signal voids in the coverage area, or overlapping interference. On the other hand, manually adjusting cable positions requires calibrating the phase of each cable individually, making the installation and debugging of a single phase shifter time-consuming. Therefore, we propose a phase shifter cavity suitable for antennas to address these issues. Utility Model Content
[0004] The purpose of this invention is to provide a phase shifter cavity suitable for antennas to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a phase shifter cavity suitable for antennas, comprising a phase shifter cavity shell, two sets of wire-laying brackets installed at the top of the phase shifter cavity shell, multiple sets of break slots provided between the two sets of wire-laying brackets, a guide rail fixed to the front exterior of the phase shifter cavity shell, multiple sets of guide slides installed inside the guide rail, a sleeve installed at the top of each guide slide, a reinforcing bracket connected to the sleeve via an elastic component, a locking rod installed at the rear end of the reinforcing bracket, a locking seat installed on the outer wall of the rear end of the phase shifter cavity shell, multiple sets of locking holes equally spaced on the locking seat, and the locking rod passing through the locking holes on the locking seat.
[0006] As an improved technical solution, the elastic component includes a connecting bracket that is movably inserted into the sleeve, a movable column fixed at the bottom end of the connecting bracket, the top end of the connecting bracket being connected to the bottom of the reinforcing bracket, and a return spring wound around the outside of the connecting bracket.
[0007] As an improved technical solution, the bottom of the reinforcing bracket is provided with two sets of positioning grooves, and both sets of positioning grooves are arc-shaped.
[0008] As an improved technical solution, the diameter of the locking rod is the same as the inner diameter of the lock hole.
[0009] As an improved technical solution, the surface of the reinforcing bracket is ground as a whole.
[0010] As an improved technical solution, the outer wall of the movable column is fully fitted with the inner wall of the sleeve, and the movable column and the inner wall of the sleeve are slidably connected.
[0011] As an improved technical solution, the two ends of the return spring are respectively connected to the outer wall of the top of the movable column and the top of the inner wall of the sleeve, and the movable column is elastically connected to the top of the inner wall of the sleeve through the return spring.
[0012] After adopting the above technical solution, the beneficial effects of this utility model are:
[0013] I. This utility model, by installing multiple sets of cable-laying brackets at the top of the phase shifter cavity shell, allows for the rapid positioning and arrangement of coaxial cables within two sets of cable-laying brackets, effectively preventing the coaxial cables from intertwining and tangling. Multiple separation slots are provided between the cable-laying brackets to facilitate cable docking within the brackets, ensuring accuracy during coaxial cable docking without relying on manual visual alignment, guaranteeing consistency of multi-channel phase differences, and effectively improving installation efficiency. Furthermore, a horizontally movable sleeve is installed on the side of the phase shifter cavity shell, and a liftable reinforcing bracket is installed on the sleeve. This allows the reinforcing bracket to quickly fix its position by inserting a locking rod into a corresponding locking hole. The reinforcing bracket is then moved to the top of the cable-laying bracket via an elastic component, maintaining downward pressure on the coaxial cable within the cable-laying bracket to prevent it from detaching.
[0014] II. This utility model has a liftable movable column installed inside the sleeve, which allows the return spring to release its elasticity, push the movable column to return to its original position, and allow the movable column to move the reinforcing bracket downwards, so that the reinforcing bracket and the cable in the cable laying bracket maintain flexible contact, thereby preventing phase shift caused by cable loosening and further improving the stability of the equipment during use.

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0023] This utility model provides a technical solution: such as Figures 1 to 6 As shown, in this embodiment, a phase shifter cavity suitable for an antenna includes a phase shifter cavity shell 1. Two sets of wire-laying brackets 2 are installed at the top of the phase shifter cavity shell 1. Multiple sets of break slots 3 are provided between the two sets of wire-laying brackets 2. A guide rail 4 is fixed to the front exterior of the phase shifter cavity shell 1. Multiple sets of guide slide plates 5 are installed inside the guide rail 4. A sleeve 6 is installed at the top of each guide slide plate 5. The sleeve 6 is connected to a reinforcing bracket 7 through an elastic component. A locking rod 9 is installed at the rear end of the reinforcing bracket 7. A locking seat 10 is installed on the outer wall of the rear end of the phase shifter cavity shell 1. Multiple sets of locking holes 11 are opened at equal intervals on the locking seat 10. The locking rod 9 passes through the locking holes 11 on the locking seat 10.
[0024] By installing multiple sets of cable trays 2 at the top of the phase shifter cavity shell 1, coaxial cables can be quickly positioned and arranged within the two sets of cable trays 2, effectively preventing the coaxial cables from intertwining. Multiple sets of break slots 3 are provided between the cable trays 2 to facilitate the connection of cables within the cable trays 2, ensuring the accuracy of coaxial cable connection without relying on manual visual alignment, ensuring the consistency of multi-channel phase difference, and effectively improving installation efficiency. Furthermore, by installing a horizontally movable sleeve 6 on the side of the phase shifter cavity shell 1, and installing a liftable reinforcing bracket 7 on the sleeve 6, the reinforcing bracket 7 can quickly fix the position of the reinforcing bracket 7 by inserting the locking rod 9 into the corresponding locking hole 11. Then, the reinforcing bracket 7 can be moved to the top of the cable tray 2 through the elastic component, so that the reinforcing bracket 7 maintains downward pressure on the coaxial cable within the cable tray 2, preventing the coaxial cable from detaching from the cable tray 2.
[0025] In other embodiments, the elastic component includes a connecting bracket 12 that is movably inserted into the sleeve 6, a movable column 13 fixed at the bottom end of the connecting bracket 12, the top end of the connecting bracket 12 connected to the bottom of the reinforcing bracket 7, and a return spring 14 wound around the outside of the connecting bracket 12.
[0026] By installing a liftable movable column 13 inside the sleeve 6, the reinforcing bracket 7 can be pulled, causing the reinforcing bracket 7 to slide upward within the sleeve 6 along with the movable column 13. The return spring 14 is compressed and deformed by the movable column 13, storing energy. When the tension on the reinforcing bracket 7 is released, the return spring 14 releases its elasticity, pushing the movable column 13 downward to reset, and causing the movable column 13 to move the reinforcing bracket 7 downward. This ensures that the reinforcing bracket 7 maintains flexible contact with the cable inside the cable feeding bracket 2, thereby preventing phase shift caused by cable loosening and further improving the stability of the equipment during use.
[0027] In other embodiments, the bottom end of the reinforcing bracket 7 is provided with two sets of positioning grooves 8, and both sets of positioning grooves 8 are arc-shaped.
[0028] This design allows the reinforcing bracket 7 to move to the upper end of the two sets of cable laying brackets 2, pressing down on the cable inside the cable laying bracket 2, thereby preventing the cable from bending angle deviation due to twisting and ensuring phase difference consistency.
[0029] In other embodiments, the diameter of the locking rod 9 is the same as the inner diameter of the lock hole 11;
[0030] With this design, when the locking rod 9 is inserted into the locking hole 11 on the lock seat 10, the locking hole 11 is locked to the position of the reinforcing bracket 7, ensuring the stability of the reinforcing bracket 7 during use.
[0031] In other embodiments, the entire surface of the reinforcing bracket 7 is ground.
[0032] This design increases the friction between the reinforcing bracket 7 and the hand, making it easier to pull the reinforcing bracket 7 effectively.
[0033] In other embodiments, the outer wall of the movable column 13 is fully fitted with the inner wall of the sleeve 6, and the movable column 13 and the inner wall of the sleeve 6 are slidably connected.
[0034] This design effectively prevents the movable column 13 from shaking significantly during its movement as it moves up and down inside the sleeve 6, thereby improving the stability of the movable column 13 in moving the reinforcing bracket 7.
[0035] In other embodiments, the two ends of the return spring 14 are respectively connected to the outer wall of the top of the movable column 13 and the top of the inner wall of the sleeve 6, and the movable column 13 is elastically connected to the top of the inner wall of the sleeve 6 through the return spring 14;
[0036] This design allows the return spring 14 outside the connecting bracket 12 to continuously apply downward elastic force to the movable column 13, enabling the movable column 13 to drive the reinforcing bracket 7 and the locking rod 9 to move downward, allowing the locking rod 9 to insert into the lock hole 11 above the lock seat 10, and allowing the reinforcing bracket 7 to maintain downward pressure on the coaxial cable inside the cable feeding bracket 2, preventing the coaxial cable from detaching from the cable feeding bracket 2.
[0037] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
