A double-layer self-contained buckle phase shifter

Abstract

The invention discloses a double-layer buckle-containing phase shifter bracket comprising a bracket body and multiple buckles mounted on the two sides of the bracket body. The bracket body is equipped with positioning columns and mounting studs. Upper and lower layers of PCB are mounted on the bracket body. Phase shifter wire clips are inserted into the positions at the two ends of the PCB, and the phase shifter wire clips fix cables through the buckles. The PCB is provided with positioning holes and mounting holes, the positioning columns on the bracket body are inserted into the positioning holes, and the mounting studs on the bracket body are inserted into the mounting holes. A plastic nut is screwed on each mounting stud. According to the double-layer buckle-containing phase shifter bracket of the invention, the problem that the space is not enough and cables are super-long when phase shifters are arranged separately is solved through a double-layer arrangement structure. Because of the special structure of the buckles, the mold structure is greatly simplified and the mold cost is greatly reduced on the premise of ensuring firm cable clamping.

Description

technical field [0001] The invention relates to a double-layer phase shifter with buckles. Background technique [0002] With the rapid development of wireless communication technology, phase-adjustable antennas are being used more and more due to their huge advantages over fixed-tilt antennas in terms of site location, number of antennas, and installation and use. There are various types of phase shifters, but the PCB phase shifter has become the first choice of a large part of people because of its cost, ease of processing and debugging. However, limited by its own material, the PCB board and the welding place between the board and the cable will also produce a certain relative vibration during the vibration of the antenna, which will affect the stability of the entire antenna. In severe cases, there will be a welding layer at the welding place between the board and the cable. The fracture mechanism disables the phase shifter. At the same time, the phase shifters are use...

AI Technical Summary

Problems solved by technology

[0006] But for the first method, its function is only to support the phase shifter, and the plate and the vibration of the plate and cable welding cannot be solved. At the same time, multiple phase shifters can only be arranged separately, and the space and cable length cannot be solved. problem; although the second method solves the vibration problem of the phase shifter PCB board itself, it cannot effectively solve the problem of vibration at the plate and cable welding, as well as the problem of space and line length
