Problems solved by technology

These two cables have the following problems when applied to 5G signal coverage: Although the HCAAYZ-50-12 cable meets the operating frequency range of 0-6GHz, due to its small structure size, high-frequency transmission signal attenuation is large, and the transmission distance is short. It is suitable for use as a 5G high-frequency signal transmission line; HCTAYZ-50-22 is limited in frequency due to its relatively large structural size, and the large structural size of the cable has bending properties, which makes installation and wiring difficult, and is not suitable for 5G high-frequency Signal transmission lines are used, so we propose a low-loss flexible feeder coaxial cable for 5G indoor distribution to solve the above problems

Abstract

The low-loss flexible feeder coaxial cable comprises an inner conductor layer, an insulating layer, an outer conductor layer and a sheath layer which are sequentially arranged from inside to outside, and the inner conductor layer, the insulating layer, the outer conductor layer and the sheath layer are coaxially arranged and connected with one another. The outer conductor layer and the inner conductor layer are both of a regular spiral embossed copper pipe structure, the insulating layer is a large-foaming-degree polyolefin foaming insulating layer, low direct-current resistance and low insulating dielectric constant can be kept, the transmission loss of the cable is greatly reduced, and the bending performance of the cable is optimized. The technical field of coaxial cables is adapted.

Description

Technical field [0001] The present invention relates to the field of coaxial cable technology, in particular to a low loss flexible feeder coaxial cable applied to 5G chamber division. Background [0002] Feeder coaxial cable is used in the field of wireless communication, and there are also wide applications in indoor wireless signal coverage. At present, the structure of the coaxial cable covered by indoor signals is used: the inner and outer conductors are made of solid copper-clad aluminum or air copper tubes, the insulation is made of foamed polyethylene, and the outer conductors are annular rolled copper tubes, and the specific product models are HCAAYZ-50-12 and HTAYZ-50-22. These two cables have the following problems when applied to 5G signal coverage: although the HCAAYZ-50-12 cable meets the frequency range of 0~6GHz, it is not suitable for use as a 5G high-frequency signal transmission line due to its small structure size, large attenuation of high-frequency transmiss...
