Description

Technical Field

[0001] The utility model relates to the field of cables, in particular to a radio frequency coaxial cable connector installation tool and a radio frequency coaxial cable. Background Art

[0002] RF coaxial cable is a cable specially used for transmitting electromagnetic energy in the RF range. It has the characteristics of wide transmission bandwidth, high protection against external interference, small antenna effect, small radiation loss, simple structure, convenient installation and good economy. RF coaxial cable plays an important role in the RF transmission of radio communications, broadcasting and television.

[0003] However, relying solely on the structure of the cable itself cannot fully meet the needs of practical applications. When connecting, branching or transferring cables, RF connectors are needed to ensure stable signal transmission and connection reliability. RF connectors are devices specially designed to connect RF coaxial cables. Their function is to ensure electrical connection between cables and minimize signal loss and interference.

[0004] RF coaxial cables need to be installed with RF connectors before they can be connected and used in communication links. Since a large number of RF coaxial cables are needed in wireless communication indoor distribution systems, the installation efficiency and quality of the cable connectors are crucial. The outer conductor structure of the RF coaxial cable with a copper tube type of outer conductor corrugated portion is a wavy curved surface structure. The annular curved surface is a dimensional structure in which the crests, troughs, and pitches are kept consistent according to design requirements. During the installation of the RF connector, the crest position needs to be cut in a circular manner. The usual method is to use a saw for manual cutting, but in actual operation, the technical requirements for manual labor are relatively high. During circular cutting, the cut surface can easily deviate from the crest position if not carefully cut, which has an adverse effect on the construction quality and efficiency.
