Problems solved by technology

However, the structure and size of the RG141 cable determine that its attenuation is too large, so it is not suitable for high-gain antennas; and if the RG250 is used instead of the RG141 cable, the cost of the coaxial cable used in the antenna will increase by nearly 200%, and the larger size of the RG250 will cause The cable bending radius increases, which is also not conducive to the wiring inside the antenna
[0003] In addition, the outer conductor of the high-temperature cable in the prior art usually adopts the process of braiding tinned copper wire + immersion tin. The outer conductor of this structure will crack after repeated bending, and such as figure 1 As shown, the strength of the connector root of the high-temperature cable assembly used in the antenna and the welding part of the cable is poor, and it is easy to cause cracking of the outer conductor of the cable when it is bent. question

Abstract

The invention relates to a high temperature resistance cable for a mobile base station and belongs to the technical field of mobile base station fittings. The high temperature resistance cable for the mobile base station comprises an inner conductor, a PTFE insulation layer, an outer conductor and a sheath, wherein the PTFE insulation layer has at least one hollow channel extending along an inner conductor extension direction, the multiple hollow channels and the inner conductor are parallel, and the multiple hollow channels are symmetrically arranged around the inner conductor. The high temperature resistance cable is advantaged in that dimensions of the high temperature resistance cable are similar to those of routine semi-flexible cables, high strength, excellent bendability, low intermodulation and low loss are realized, and the high temperature resistance cable can excellently adapt to miniaturization and large gain trend requirements of the mobile base station.

Description

technical field [0001] The invention relates to the technical field of mobile base station accessories, and more specifically, the invention relates to a high temperature resistant cable for a mobile base station. Background technique [0002] In the field of mobile communication, the miniaturization and large gain of mobile base station antennas are the future development trend. At present, the conventional high-temperature cables used in base station antennas have the characteristics of high temperature resistance, low intermodulation, good bending performance, and good mechanical phase stability, such as RG141 semi-flexible cables. However, the structure and size of the RG141 cable determine that its attenuation is too large, so it is not suitable for high-gain antennas; and if the RG250 is used instead of the RG141 cable, the cost of the coaxial cable used in the antenna will increase by nearly 200%, and the larger size of the RG250 will cause The increased bending radi...
