[0002] Humanoid robots, also known as embodied intelligent robots, have a wide range of applications in industry, military, medical, and service sectors. These robots perceive their surroundings through various sensors, cameras, and radar. The cameras, in particular, require sophisticated video and data transmission capabilities; therefore, the video transmission cables used must possess properties such as low loss, interference resistance, torsion resistance, mechanical shock resistance, compression resistance, and wear resistance.

These products have poor anti-interference capabilities and are prone to data loss or malfunction under dynamic bending and complex electromagnetic environments. Therefore, improving the safety and reliability of these products in complex application scenarios is essential. Summary of the Invention

The aluminum foil layer of the second shielding strip is in contact with the current-carrying core. The substrate layer of the second shielding strip is a PP film layer, and the substrate layer of the first shielding strip is a PET film layer.

[0006] The following are further improvements to the above technical solution:

[0007] 1. In the above scheme, the thickness of the aluminum foil layer of the first shielding strip and the second shielding strip is 0.012 mm ~ 0.016 mm.

[0008] 2. In the above scheme, the adhesive layers of the first shielding strip and the second shielding strip are both non-polar low-loss adhesives.

[0009] 3. In the above scheme, the insulation layer of the signal transmission core wire is a TPX insulation layer or a PP insulation layer.

[0010] 4. In the above scheme, the insulation layer of the power transmission core wire is a PP insulation layer or an HDPE insulation layer.

[0011] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0012] This utility model relates to an anti-interference robot video cable.
