Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a tail fastener for a radio frequency connector. Background Art

[0002] At present, the following several methods are adopted for fastening the tail of a radio frequency connector: 1. Using a C-shaped cable clamp for connection and fastening. The disadvantage is that it is easy to cause uncontrollable damage to the cable outer skin during clamping. The C-shaped cable clamp is relatively large in size, resulting in a large change in the cable outer diameter, and it is difficult to process the braided wire for shielding, and it is easy to cause pulling off; 2. Using an O-shaped rubber ring in cooperation with a retaining ring type tail clip. The disadvantage is that it is difficult to install the tail rubber ring, has high requirements for the stripping length of the cable, the operation is complicated, and the risk of falling off is relatively large; 3. Using a shielding ring and adopting a crimping type fixation. The disadvantage is that different models need to be paired with special crimping tools. The crimping operation has high requirements for the trimming length of the cable shielding wire, and it is easy to cause damage to the connector during crimping. Therefore, it is necessary to provide a tail fastener for a radio frequency connector to solve or at least partially solve the above problems. Summary of the Utility Model
