Abstract
Description
Technical Field

[0002] Coaxial cables are often used for signal transmission in various electronic products, especially in the fields of RF signal transmission and antennas. The board-end connector is soldered on the circuit board of the electronic product. The line-end connector includes a line-end center terminal and a line-end shielding terminal. The line-end center terminal is electrically connected to the center conductor (usually called the core wire) of the coaxial cable, and the line-end shielding terminal is electrically connected to the outer conductor of the coaxial cable. The line-end connector can be mated to the board-end connector.
[0003] In order to ensure the sealing and waterproof performance of the cable and its connector, the RF coaxial cable assembly is generally covered with a heat shrink tubing at the connection between the cable and its connector for protection. However, the heat shrink tubing on the surface is prone to cracking or even damage after long-term use, resulting in a short service life of the heat shrink tubing, thereby reducing the protection capability of the RF coaxial cable assembly and shortening the service life of the RF coaxial cable assembly. In addition, the existing RF coaxial cable assembly has insufficient anti-interference ability and is prone to signal leakage. Utility Model Content

The inner surfaces of the two side blocks 602 are slidably connected to the outer protection sleeve 605.
[0027] The heat shrink sleeve 5 needs to be protected. First, the side protection sleeve 601 is sleeved on the outer surface of the heat shrink sleeve 5, and then the inner protection sleeve 604 is pulled to rotate to the other side inside the side protection sleeve 601. The inner protection sleeve 604 rotates under the guidance of the first arc block 603, thereby covering the other side of the heat shrink sleeve 5, and then the outer protection sleeve 605 is rotated on the inner side wall of the block 602 and the outer surface of the side protection sleeve 601. The outer protection sleeve 605 drives the second arc block to rotate inside the second arc groove on the outer surface of the side protection sleeve 601, and then the inner protection sleeve 604 and the outer protection sleeve 605 are fixed to the surface of the side protection sleeve 601 by the limiting bolt 608, thereby achieving the effect of protecting the heat shrink sleeve 5, thereby improving the protection capability of the RF coaxial cable assembly and extending the service life of the RF coaxial cable assembly.
[0028] In order to fix the inner protective sleeve 604 and the outer protective sleeve 605, as shown in FIG.
