The protective tube 200 is constructed by sequentially connecting multiple corrugated tubes 210 end-to-end. Each corrugated tube 210 has an A-port 220 and a B-port 230 at both ends for mutual insertion and adaptation. The outer wall of the A-port 220 and the inner wall of the B-port 230 are respectively provided with a protrusion 2210 and a groove 2310 for snap-fit ​​fixing. The bushing 300 is composed of multiple foam tubes 310 spliced ​​together. The outer wall of the foam tubes 310 has an axial installation seam 320 for easy installation and adjustment. Specifically, during operation, the first... First, the signal cable 100, as the main body for signal transmission, is encased inside a bushing 300 composed of multiple foam tubes 310.
