Embodiment Construction

[0017] see figure 1 : A novel radio frequency coaxial cable structure suitable for use at the test level, comprising a wire core 1, the wire core 1 is a multi-strand wire core, and the wire core 1 is wound with an insulator 2 and an outer conductor-3 successively , outer conductor two 4, sheath one 5, spring 6, braiding layer 7, sheath two 8, transition layer 9 and sheath three 10, the transition layer 9 is an intermediate layer with rubber, and the material of the insulator 2 is low Density PTFE film band, the material of described spring 6 is high-strength stainless steel material.

[0018] In the present invention, the spring 6 is made of high-strength stainless steel, and the metal braiding layer wound outside has a braiding density of more than 90%. Due to the small braiding pitch, the torsion resistance of the spring can be strengthened. The interior adopts spring + braiding layer. Although the outside of the spring is restrained by the braiding layer, there is still a ...

Abstract

The invention relates to a structure of radio frequency coaxial cables, in particular to a novel structure of radio frequency coaxial cables suitable for testing. The conventional structure of radio frequency coaxial cables has defects of poor testing precision and short practical service life. The novel structure of the radio frequency coaxial cables suitable for testing comprises a core and is characterized in that: an insulator, an outer conductor 1, an outer conductor 2, a sheath 1, a spring braid layer, a sheath 2, an intermediate layer, and a sheath 3 are wound on the core sequentially. The spring structure is adopted and sheathes and a nylon rayon mesh are tightly connected through an adhesive layer, so the influence of external force or torsion on internal cables is basically eliminated, the precision of tested cables is guaranteed, influence on the performance index of tested cables because of testing error of tested cables can be reduced, the mechanical bent service life of tested cables can be prolonged because of the outer protection structure of cables.

Description

1. Technical field: [0001] The invention relates to a structure of a radio frequency coaxial cable, in particular to a novel structure of a radio frequency coaxial cable suitable for testing level. 2. Background technology: [0002] In recent years, with the rapid development of microwave communication technology, the whole equipment has put forward many new requirements for radio frequency transmission components. As far as radio frequency coaxial connectors and cable assemblies are concerned, DC-Block connectors, radio frequency switch connectors, Multifunctional connectors such as signal lightning protection connectors have been widely used in the whole system, and the market for phase-stable cables and cable assemblies is also growing rapidly. These new microwave components are of great help to improve the quality of radio frequency signal transmission and the signal quality of the whole system , Simplifying the structure of the whole machine plays a very important role....
