[0026] like Figure 1 and Figure 2 As shown, the conductor includes a core 8, which is located at one end of the inner cavity of the first circular shell 1 and the second circular shell 2, passes through a through hole 7 and is wound around the first limiting groove 5 and the second limiting groove 6. The side wall of the core 8 is provided with an insulating film 9, the side wall of the insulating film 9 is provided with an anti-interference film 10, the side wall of the anti-interference film 10 is provided with a waterproof layer 11, and the side wall of the waterproof layer 11 is provided with a rubber layer 12.

[0027] When the anti-interference film 10 is provided on the wire core 8, the materials commonly used include insulating materials such as polyethylene or polyvinyl chloride. The principle of these anti-interference films 10 is mainly to provide an isolation layer to reduce the interference of external electromagnetic radiation on the wire core 8 and maintain the stability and reliability of signal transmission;

[0028] The anti-interference film 10 is usually made of metal material, such as aluminum foil or copper foil, as a shielding layer around the wire core 8, which can effectively block external electromagnetic radiation and improve the anti-interference ability of the wire.

[0029] like Figure 4 and Figure 5 As shown, the first limiting groove 5 and the second limiting groove 6 are located on the outer side of the wire core 8 and are adhered with insulating glue 21 .

[0030] Specifically, the winding method of the insulating adhesive 21 can be manually or with the help of some external tools, and the material and structure of the insulating adhesive 21 belong to the existing technology and will not be described in detail here.

It has a simple structure, is easy to install on site, and has great flexibility.

[0035] Working principle: When docking the wire cores 8, first insert the wire cores 8 on both sides into the first conductive tube 3 and the second conductive tube 4 respectively, then pass through the through hole 7 and wrap around the first limiting groove 5 and the second limiting groove 6, and use the insulating glue 21 to insulate the exposed wire core 8 part, then rotate the screw 16 to drive the push plate 15 to squeeze the sealing block 14, and the sealing block 14 is squeezed to move closer to the side of the wire core 8 through the inclined surface of the annular groove 13, exerting an extrusion force on it, and forming a ring to seal it to prevent external dust and moisture from entering, and then the first circular shell 1 and the second circular shell 2 are rotationally connected through the screw sleeve 19 and the screw hole 20, and at the same time, the first conductive tube 3 enters the second conductive tube 4 through the thread for stable connection, effectively avoiding interference from external factors such as loose connections, thereby improving its stability.
