[0014] The present patent can be further understood through the specific embodiments given below, but they are not intended to limit the present patent.

[0015] Example 1: An IoT sensor connection cable includes: at least two signal transmission cores 1, at least two power cores 2, a ground wire 3, and an outer sheath 4. The outer sheath 4 covers the outside of the cable core formed by twisting the signal transmission cores 1, power cores 2, and outer sheath 4. A first outer shielding layer 5 and a second outer shielding layer 6 are stacked sequentially between the cable core and the outer sheath 4. A first inner shielding layer 7 covers the outside of the signal transmission cores 1, and a second inner shielding layer 8 covers the outside of the power cores 2. Signal transmission and power transmission are shielded separately, which can further reduce the impact of cable transmission on signal transmission and has better anti-electromagnetic interference performance. The first inner shielding layer 7 further includes a metal braided layer 71 and elastic substrate layers 72 respectively disposed on both sides of the metal braided layer 71. The metal braided layer 71 and the elastic substrate layers 72 are connected by adhesive bonding.

[0016] The second inner shielding layer 8 is a metal braided shielding layer; the first outer shielding layer 5 is a metal braided shielding layer; and the second outer shielding layer 6 is formed by overlapping double-sided aluminum foil strips wrapped around the outside of the first outer shielding layer 5.

[0017] Example 2: An IoT sensor connection cable includes: at least two signal transmission cores 1, at least two power cores 2, a ground wire 3, and an outer sheath 4. The outer sheath 4 covers the outside of the cable core formed by twisting the signal transmission cores 1, power cores 2, and outer sheath 4. A first outer shielding layer 5 and a second outer shielding layer 6 are stacked sequentially between the cable core and the outer sheath 4. A first inner shielding layer 7 covers the outside of the signal transmission cores 1, and a second inner shielding layer 8 covers the outside of the power cores 2. The first inner shielding layer 7 further includes a metal braided layer 71 and elastic substrate layers 72 respectively disposed on both sides of the metal braided layer 71. The metal braided layer 71 and the elastic substrate layers 72 are connected by adhesive bonding.

[0018] The aforementioned signal transmission core wire 1 and power core wire 2 each include a conductor made of multiple strands of conductive filaments twisted together. They are made of Category 6 ultra-fine oxygen-free copper wire, with a positive and negative composite twisted structure of Z-twisted strands and S-twisted strands. The overall structure has high flexibility and high bending resistance.

[0019] The second inner shielding layer 8 is an aluminum foil wrapped shielding layer; the outer sheath 4 is a polyurethane sheath, preferably a high-strength, scratch-resistant polyether flame-retardant polyurethane.

[0020] Further explanation: This application only improves the structure of the cable. The improved cable structure can be produced and processed using existing production equipment and corresponding product lines. Therefore, the processing procedure is not described in detail.

[0021] The IoT sensor connection cable described above improves overall anti-interference performance and shielding performance during long-term use, especially the stability of signal transmission shielding performance, through the combination of inner and outer shielding layers and signal transmission shielding layers.
