Problems solved by technology

[0002] Coaxial cable is an important connection material in communication engineering. When coaxial cable is required, the space span is relatively large, the signal strength is limited, and the anti-interference ability of the signal is poor. Therefore, the impedance, attenuation and anti-interference ability of the communication cable The requirements for standing wave capability are relatively high. Traditional cables are constantly improving in this direction, but the effect is limited.
[0003] In some occasions, due to the small space, the coaxial cable needs to be highly flexible, which can be bent arbitrarily to a certain extent, but the traditional coaxial cables do not have good flexibility.

Abstract

A method for producing flexible low-standing-wave corrugated coaxial cables is characterized by comprising the following steps of manufacturing inner conductors, manufacturing insulating media, manufacturing outer conductors and manufacturing a sheath. The flexible low-standing-wave corrugated coaxial cables produced by means of the method adopt through an accurate control manufacture process, stability consistency is ensured, and good impedance uniformity and standing wave stability are guaranteed. An insulating layer is stable in foaming degree and has very good electrical performance, and especially high-frequency attenuation performance is low. The outer conductors are good in bending performance.

Description

technical field [0001] The invention relates to a production method of a flexible low standing wave corrugated coaxial cable, which belongs to the communication field. Background technique [0002] Coaxial cable is an important connection material in communication engineering. When coaxial cable is required, the space span is relatively large, the signal strength is limited, and the anti-interference ability of the signal is poor. Therefore, the impedance, attenuation and anti-interference ability of the communication cable The requirements for standing wave capability are relatively high. Traditional cables are constantly improving in this direction, but the effect is limited. [0003] In some occasions, due to the small space, the coaxial cable needs to be highly flexible and can be bent arbitrarily to a certain extent, but the traditional coaxial cables do not have good flexibility. Contents of the invention [0004] In order to solve the problems in the prior art, the...
