Abstract
Description
Technical Field
[0001] This utility model relates to a power connection cable for a robot, belonging to the field of intelligent robot technology. Background Technology
[0002] Giant intelligent robots, also known as humanoid robots, have a wide range of applications in industry, military, medical, and service sectors. Precise control between the robot's joints is a key indicator of intelligent control. The motor power cables used in the rotating modules require low loss, interference resistance, torsion resistance, mechanical shock resistance, compression resistance, and wear resistance. Currently, most motor power cables on the market use two single-core insulated wires for power connection. This can lead to the insulation wires becoming tangled and interfering with each other during installation. Friction or misalignment can occur during the rotation or torsion of the robotic arm, potentially causing wire breakage and loss of conductivity in complex scenarios or at high speeds. Summary of the Invention
[0003] The technical problem to be solved by this utility model is to provide a power connection cable for a robot. This power connection cable reduces the laying space occupied during use and avoids adverse interference caused by mutual friction and misalignment between core wires in complex dynamic usage scenarios.
[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a power connection wire for a robot, comprising: a first insulated core wire and a second insulated core wire, each of the first and second insulated core wires comprising a conductor and an insulating layer covering the outside of the conductor, the first and second insulated core wires extending along their respective length directions being parallel and spaced apart, and the insulating layers of the first and second insulated core wires being connected by a rib extending along the length directions of the first and second insulated core wires.
[0005] The following are further improvements to the above technical solution:
[0006] 1. In the above scheme, the width of the rib is 0.1mm~0.3mm and the thickness is 0.2mm~0.5mm.
[0007] 2. In the above scheme, the reinforcing bar, the insulation layer of the first insulated core wire, and the insulation layer of the second insulated core wire are integrally formed.
[0008] 3. In the above scheme, the insulating layer tightly covering the outside of the conductor is a low dielectric constant elastic insulating layer.
[0009] 4. In the above scheme, the insulating layer is a PVC insulating layer, a TPE insulating layer, or a TPV insulating layer.
[0010] 5. In the above scheme, the conductor is an oxygen-free copper conductor, a copper-clad steel conductor, or a copper alloy conductor.
[0011] 6. In the above scheme, the conductor is a soft copper-clad steel conductor with a tensile strength ≥400MPa, elongation ≥20%, and conductivity ≥45%.
[0012] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:
[0013] The power connection cable of this utility model robot has a first insulated core wire and a second insulated core wire that extend parallel to each other and spaced apart along their respective lengths. The insulation layers of the first insulated core wire and the second insulated core wire are connected by a rib extending along the lengths of the first and second insulated core wires. The rib connects the two insulated core wires to form a flat cable with a fixed relative position between the core wires. This reduces the laying space occupied during use, avoids adverse interference caused by mutual friction and displacement between the core wires in complex dynamic use scenarios, and facilitates the connection operation between the two ends of the cable and the outside.
