[0002] The cable connector is a component in the cable line. It is used to connect two sections of cable and improve the electric field at the ends of the two cables. European cable connectors, that is, cable connectors that meet European standards, are divided into European cable front connectors and European cable rear connectors. The mainstream European rear connectors on the market have the following problems: 1. They cannot effectively prevent electromagnetic interference cables; 2. The cable connection is frequently pulled or the pulling force is maintained for a long time, which makes the connection loose, resulting in reduced waterproof sealing. In view of the above two points, the existing European rear connectors are improved and optimized. Utility Model Content

The stress cone is provided with at least one sealing ring installation groove for sleeve installation of the end sealing ring, a cable locking tooth group arranged around an arc interval and a magnetic ring positioning groove for positioning the anti-interference magnetic ring at the cable passing hole from bottom to top. The cable locking tooth group includes a large locking tooth and a small locking tooth. A shell upper limit protrusion and a shell lower limit protrusion for upper and lower limit of the stress cone are provided in the connector shell, and the stress cone assembly is injection molded in the connector shell insert.

[0005] The shell terminal includes a terminal body, a terminal cone portion and a terminal tightening portion, and the stress cone includes a stress cone body, a stress cone locking portion and a stress cone sealing portion which are sequentially fitted with the terminal body, the terminal cone portion and the terminal tightening portion, the stress cone body is provided with the magnetic ring positioning groove, the stress cone locking portion is provided with the cable locking tooth group, and the stress cone sealing portion is provided with the sealing ring installation groove.
