Technical Field

[0001] This utility model relates to a video cable for intelligent robots, belonging to the field of new energy and energy-saving technology. Background Technology

[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.

[0003] Currently, most video cables on the market consist of a data transmission cable made by twisting two single-core insulated wires together and a power cable made of two insulated core wires, which are then braided and sheathed. 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

[0004] The technical problem to be solved by this utility model is to provide a video cable for intelligent robots. This video cable for intelligent robots can improve shielding performance, reduce skin effect, and improve overall bending resistance while reducing cable outer diameter.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a video cable for intelligent robots, comprising: a data transmission line composed of at least two signal transmission cores, a power line composed of at least two power transmission cores, and a sheath covering the outside of the data transmission line and the power line. Each of the signal transmission cores and the power transmission cores includes a conductor and an insulation layer covering the outside of the conductor. A shielding strip is wrapped around the outside of the cable core formed by twisting at least two signal transmission cores and at least two power transmission cores. The shielding strip includes a substrate layer with one side surface attached to the cable core and an aluminum foil layer attached to the other side surface of the substrate layer by an adhesive layer. A metal braided layer is disposed between the shielding strip and the sheath layer, which is in contact with the aluminum foil layer of the shielding strip. The metal braided layer is obtained by braiding several conductor strands, each conductor strand including 4 to 6 conductor single wires. The conductor single wire is obtained by tightly winding several round conductor single wires around several fiber single wires.

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

[0007] 1. In the above scheme, the circular conductor monofilament is a tin-plated copper monofilament with a diameter of 0.05mm to 0.08mm.

[0008] 2. In the above scheme, the fiber monofilament is an aramid monofilament or a polyarylate fiber monofilament.

[0009] 3. In the above scheme, the entanglement coverage between the circular conductor monofilament and the fiber monofilament is 100%.

[0010] 4. In the above scheme, the weaving angle of the metal braided layer is no greater than 45 degrees.

[0011] 5. In the above scheme, the diameter of the single conductor wire is 0.2mm~0.25mm.

[0012] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0013] This utility model relates to a video cable for intelligent robots. The cable core, formed by twisting together at least two signal transmission cores and at least two power transmission cores, is wrapped with a shielding strip. The shielding strip includes a substrate layer with one side surface in contact with the cable core and an aluminum foil layer attached to the other side surface of the substrate layer via an adhesive layer. A metal braided layer, in contact with the aluminum foil layer of the shielding strip, is disposed between the shielding strip and the sheath layer. The metal braided layer is obtained by braiding several conductor strands, each conductor strand including 4-6 conductor single wires. Each conductor single wire is obtained by tightly winding several round conductor single filaments around several fiber single filaments. This design improves shielding performance, reduces the skin effect, and enhances overall bending resistance while reducing the cable's outer diameter. Attached Figure Description
