Description

Technical Field

[0001] This utility model relates to a transmission cable for a humanoid robot, 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 transmission cable for a humanoid robot, which improves the shielding performance and avoids problems such as wire breakage and wear caused by the relative slippage of the metal braided layer.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a transmission cable for a humanoid robot, 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 tape 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. A metal braided layer and a wrapping tape layer are sequentially arranged between the shielding tape and the sheath layer. The sheath layer is slidably wrapped around the outside of the wrapping tape layer.

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

[0007] 1. In the above scheme, the wrapping layer is formed by overlapping PTFE raw material tape around the outside of the metal braided layer.

[0008] 2. In the above scheme, the overlap rate of the PTFE raw material tape wrapping is 40%~60%.

[0009] 3. In the above scheme, the sheath layer is a TPU sheath layer.

[0010] 4. In the above scheme, the metal braided layer is a tin-plated copper braided layer.

[0011] 5. In the above scheme, the shielding strip includes a substrate layer whose one surface is bonded to the cable core and an aluminum foil layer bonded to the other surface of the substrate layer by an adhesive layer, wherein the aluminum foil layer is bonded and in contact with the metal braided layer.

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

[0013] The transmission cable for the humanoid robot of this utility model consists of a cable core formed by twisting together at least two signal transmission cores and at least two power transmission cores, with a shielding strip wrapped around the outside. Between the shielding strip and the sheath layer, a metal braided layer and a wrapping layer are arranged in sequence. The sheath layer can slidably cover the outside of the wrapping layer. While improving the shielding performance, this avoids interference and restraint on the relative sliding of the metal braided layer, and also avoids problems such as wire breakage and wear caused by the relative sliding of the metal braided layer, thus ensuring the stability of the cable performance.
