Description

Technical Field

[0001] This utility model relates to a video transmission cable for a 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 video transmission cable for an embodied robot. This video transmission cable for the embodied robot can improve the ability to shield against interference signals and the range of signal shielding, and ensure the reliability of video and data transmission in complex scenarios. It can also effectively avoid wear and interference to the metal braided layer caused by relative sliding between layers.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a video transmission cable for a 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. The cable core formed by twisting at least two signal transmission cores and at least two power transmission cores is wrapped with a first shielding strip. A metal braided layer and a wrapping layer are sequentially arranged between the first shielding strip and the sheath layer. The sheath layer is slidably wrapped around the outside of the wrapping layer.

[0006] A second shielding strip is wrapped around the outside of a data cable core formed by twisting at least two signal transmission cores and a current-guiding core. The first shielding strip and the second shielding strip each include a substrate layer and an aluminum foil layer attached to one side of the substrate layer by an adhesive layer. The aluminum foil layer of the first shielding strip is in contact with the metal braided layer, and the aluminum foil layer of the second shielding strip is in contact with the current-guiding core.

[0007] The following are further improvements to the above technical solution:

[0008] 1. In the above scheme, the wrapping layer is formed by overlapping PTFE raw material tape around the outside of the metal braided layer.

[0009] 2. In the above scheme, the overlap rate of the PTFE raw material tape wrapping is 40%~60%.

[0010] 3. In the above scheme, the sheath layer is a TPU sheath layer.

[0011] 4. In the above scheme, the metal braided layer is a tin-plated copper braided layer with a braiding angle of no more than 45 degrees.

[0012] 5. In the above scheme, 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.

[0013] 6. In the above scheme, the insulation layer of the signal transmission core wire is a TPX insulation layer or a PP insulation layer, and the insulation layer of the power transmission core wire is a PP insulation layer or an HDPE insulation layer.

[0014] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0015] The video transmission cable of this utility model for an embodied robot comprises a cable core formed by twisting at least two signal transmission cores and at least two power transmission cores, with a first shielding strip wrapped around its outer side. A metal braided layer and a wrapping layer are sequentially disposed between the first shielding strip and the sheath layer. The sheath layer slidably covers the outside of the wrapping layer. A second shielding strip is wrapped around the outer side of a data cable core formed by twisting at least two signal transmission cores and a current-carrying core. Both the first and second shielding strips include a base material layer and are attached to one side of the base material layer by an adhesive layer. The aluminum foil layer of the first shielding strip is in contact with the metal braided layer, and the aluminum foil layer of the second shielding strip is in contact with the current-carrying core wire. Through the combination of the double-layer shielding strips and the mutual cooperation between the shielding strips and the current-carrying core wire, as well as between the metal braided layer and the outer shielding strip and the wrapping layer, it can not only improve the shielding capability and the range of signal shielding and ensure the reliability of video and data transmission in complex scenarios, but also effectively avoid the wear and interference of the metal braided layer caused by the relative sliding between the layers, and improve the overall mechanical strength, flexibility and roundness.
