The functional mechanism 3 includes an insulating layer 301, and a magnetic shielding functional layer 302 is attached to the lower end face of the insulating layer 301. The functional mechanism 3 can play a dual role among multiple strip main layers 2. The insulating layer 301 can block the electrical connection between the strip main layers 2 to prevent short circuits, while the magnetic shielding functional layer 302 can absorb and weaken the stray magnetic field generated when the strip main layers 2 are working, reducing interference to surrounding equipment. The insulating layer 301 is made of polyimide film material.

Reference Figure 4 and Figure 5The protective mechanism 5 includes a priority heat dissipation layer 504, which is made of thin aluminum foil. Utilizing the excellent thermal conductivity of the thin aluminum foil, the priority heat dissipation layer 504 directly adheres to the outer wall of the iron core 4, rapidly conducting the heat generated during the iron core's operation and providing an initial channel for heat dissipation, thus improving heat dissipation efficiency. A noise reduction layer 503, made of butyl rubber damping tape, is adhered to the outer wall of the priority heat dissipation layer 504. The noise reduction layer 503 absorbs noise generated by vibration during the iron core's operation through the elasticity and damping characteristics of the butyl rubber damping tape, reducing noise propagation intensity and improving the working environment.
