Abstract
Description
Technical Field
[0001] This utility model relates to the field of communication equipment technology, and in particular to an integrated radio frequency elbow. Background Technology
[0002] Radio frequency (RF) elbows are widely used RF connectors in the communications field, enabling RF coaxial transmission lines to bend at various angles. The most common RF coaxial elbow is the right-angle elbow, or 90° elbow. Currently, the most common RF coaxial elbows on the market are coaxial cable structures, consisting of an inner coaxial conductor and a coaxial outer shell. The inner conductor supports the insulator. In practical engineering applications, when connecting coaxial transmission lines, the inner conductor ferrule, clamp, and hose clamp are required for locking to ensure the stability and reliability of the coaxial transmission line connection.
[0003] Currently, the housings of RF elbows on the market are all welded. The welding process may generate deformation and residual stress, which may affect the dimensional accuracy and performance of the product. The heat-affected zone of the weld may cause changes in the material structure and properties, reducing the overall performance of the housing.
[0004] Furthermore, the excessive use of accessories in the connection of the RF system can easily lead to unstable connections during engineering installation. For example, at the coaxial connection of the RF elbow, the inner conductor may overheat under working conditions, resulting in excessive load and excessive reflection, which can damage the RF devices. Therefore, we propose an integrated RF elbow. Utility Model Content
[0005] The main purpose of this utility model is to provide an integrated RF elbow. By setting up a main body unit and an installation unit, it solves the problems that the outer shell of the RF elbow is made by welding. During the welding process, deformation and residual stress may occur, which will affect the dimensional accuracy and performance of the product. In addition, too many accessories are used when connecting to the RF system, which can easily cause unstable connection during engineering installation.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] An integrated radio frequency elbow includes a main body unit, a mounting unit disposed at the end of the main body unit, and a first connecting unit and a second connecting unit disposed inside the main body unit;
[0008] The main body unit includes an outer shell and a third inner conductor installed inside the outer shell;
[0009] The mounting unit includes a first stepped tube installed at one end of the housing, a second stepped tube installed at the other end of the housing, and a mounting plate disposed between the two first stepped tubes and the second stepped tube.
[0010] Preferably, the mounting unit further includes mounting holes formed on the surface of the mounting plate.
[0011] Preferably, the first connection unit includes a first insulator installed at the end of the third inner conductor and located inside the first stepped tube, and a first inner conductor installed at the end opposite to the first insulator and the third inner conductor.
[0012] Preferably, the second connection unit includes a second insulator installed at the other end of the third inner conductor and located inside the second stepped tube, and a second inner conductor installed at the end opposite to the third inner conductor of the second insulator.
[0013] Preferably, both the first inner conductor and the second inner conductor have through holes inside, and each of the first inner conductor and the second inner conductor has eight through holes around the through holes.
[0014] Preferably, both the first and second stepped tubes have limiting steps inside.
[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] In this invention, the outer shell, first stepped tube, mounting plate, and second stepped tube are integrally formed through the main body unit and the installation unit. This allows for the completion of the entire product forming process in one step, reducing subsequent welding, grinding, and other processing steps and improving production efficiency. The integrally formed shell has high dimensional accuracy and surface quality. The integral forming of the shell can minimize errors and fit problems during assembly. The mounting plate between the first and second stepped tubes, as well as the mounting plate itself, reduces the need for hose clamps and clamp accessories, greatly improving engineering installation efficiency. Limiting steps are provided inside both the first and second stepped tubes, improving the reliability and stability of the inner conductor connection. Attached Figure Description
