Description

Technical Field

[0001] The invention relates to the field of cable straightening, and in particular to a high-frequency semi-rigid cable straightening device and a process method. Background Art

[0002] With the continuous development of electronic technology, the requirements for signal transmission are getting higher and higher. Early cables had many problems in high-frequency signal transmission, such as large loss and weak anti-interference ability. In order to meet the needs of high-frequency and high-speed signal transmission, semi-rigid cables came into being. They have been improved and innovated on the basis of traditional cables and gradually become an important solution for high-frequency signal transmission. High-frequency semi-rigid cables are usually semi-rigid cables with RF connectors installed at one or both ends of the semi-rigid cables. High-frequency semi-rigid cables are usually bent into a circle for transportation. When they need to be used, they usually need to be straightened with a straightening device. A Chinese patent discloses a cable straightener (application number: 2023229264407). The patent clamps the cable by adjusting the position of the straightening roller 1 and the straightening roller 2, which can adapt to cables of different diameters. When the cable moves, the horizontal and vertical directions of the cable are straightened together, and the straightening efficiency is high; However, the above patent can only straighten cables without connectors at both ends. When RF connectors are installed at both ends of the cable, it cannot be straightened. At the same time, it can only straighten cables of a single diameter and it is difficult to straighten cables of different diameters.
