By starting the light strip 14, its line can be quickly found among many lines, which is convenient for maintenance personnel to repair.

[0025] Refer to Figure 1 , Figure 2 and Figure 3, the attenuation reduction mechanism 2 includes a plurality of heat-melt mylar 202. The plurality of heat-melt mylar 202 are fixedly connected to the inner wall of the nylon thread 201. A metal strip 203 is arranged on the outer wall of the heat-melt mylar 202. An insulating layer 204 is fixedly connected to the inner wall of the metal strip 203. A plurality of conductors 205 are fixedly connected to the inner wall of the insulating layer 204; an insulating cylinder 12 is fixedly connected to the inner wall of the rotating barrel 7, and the conductor 205 penetrates through the insulating cylinder 12;

[0026] Specifically, the nylon thread 201 can improve its firmness. The heat-melt mylar 202 can provide mechanical protection for the coaxial cable and also has the ability to prevent water and moisture. The metal strip 203 can enhance its shielding effect, improve the anti-electromagnetic radiation ability and waterproof performance. The insulating layer 204 can prevent signal interference and external corrosion. The conductor 205 can transmit electrical signals. The insulating cylinder 12 can wrap the conductor 205 when the connection is released.

[0027] Refer to Figure 1 , Figure 2 and Figure 4 , a switch 20 is fixedly connected to the outside of the left fixed disk 6. The switch 20 is electrically connected to the lamp strip 14; fixing screws 15 are arranged on the inner wall of the fixing plate 3, and a backing plate 16 is arranged on the outside of the fixing screws 15; the top of the bottom baffle 4 is rotatably connected to the top baffle 17.

[0028] Specifically, the switch 20 can control the startup and operating power of the lamp strip 14.

[0029] Working principle: Before using this device, first of all, this fixed plate 3 can easily fix the bottom plate 1 on the wall, which ensures the stability of the coaxial cable and also avoids communication interruption caused by cable loosening or falling off. At the same time, in order to further improve the stability of the coaxial cable, through the bottom baffle 4, this baffle can firmly fix the cable on the wall to prevent it from moving due to external force or gravity. The design of the baffle 4 also takes into account the diameter and material of the cable to ensure that coaxial cables of different specifications can be properly fixed. In terms of connecting devices, connect the coaxial cable together with the rotating barrel 7, and then combine the rotating barrel 7 with the contact post 8 to achieve the connection between the cable and the device. Moreover, the threaded connection between the rotating barrel 7 and the contact post 8 also enhances the firmness of the connection and effectively prevents accidental detachment. In order to facilitate maintenance personnel to quickly find the target line among numerous lines, when maintenance or repair is required, just start the light strip 13, and the required line can be quickly located. This not only improves the maintenance efficiency but also reduces the operation difficulty. At the same time, the brightness and color of the light strip 13 can also be adjusted according to needs to adapt to different working environments and requirements. And through the nylon thread 201, the firmness of the coaxial cable can be enhanced. As a high-strength material, the nylon thread 201 has good tensile and wear-resistant characteristics, can effectively resist external physical impacts, protect the cable from damage, and significantly improve the service life and stability of the cable. Secondly, the heat-melted mylar 202 plays an important mechanical protection role for the coaxial cable. The mylar material has good tensile and tear resistance properties. Through the heat-melting technology, it is tightly wrapped on the surface of the cable to form a strong barrier. In addition, the heat-melted mylar 202 also has excellent waterproof and moisture-proof capabilities. Even in harsh environmental conditions, it can effectively protect the internal structure and function of the cable from being affected. With the introduction of the metal strip 203, not only the shielding effect of the coaxial cable is enhanced, but also the anti-electromagnetic radiation and waterproof performance can be significantly improved. The metal strip 203 can form a continuous conductive layer to effectively block the intrusion of external electromagnetic interference and ensure the purity and stability of the signal. At the same time, the waterproof function of the metal strip 203 can also keep the cable working normally in a humid environment and prevent moisture from damaging the internal circuit. At the same time, the insulating layer 204 can prevent signal interference and external corrosion and ensure the transmission quality and stability of the signal. Finally, the conductor 205, as the core part of the coaxial cable, undertakes the important task of transmitting electrical signals.

[0030] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model.
