In order not to affect other components, a shielding layer is added to shield this electromagnetic field inside the cable; the protective layer protects the wires and cables from the invasion of external impurities and moisture, and prevents direct damage to the wires and cables by external forces.

The connection plug plate 61 is fixed to one side wall of the splicing sheet layer 5, and the matching groove 62 is opened on the other opposite side wall of the splicing sheet layer 5. The connection plug plate 61 of one splicing sheet layer 5 is inserted and positioned in the matching groove 62 of another adjacent splicing sheet layer 5 to realize the splicing of adjacent splicing sheet layers 5, and thereby realize the circumferential connection of the protective layer 4.
