[0008] An insulating layer surrounds the two power lines;

[0009] The wrapping layer covers the outer perimeter of the two power lines after they are twisted together;

[0010] The filler material is used to fill the gap between the two power lines, the two twisted signal lines, and the wrapping layer within the wrapping layer;

[0011] The sheath tightly covers the outer layer of the strap.

[0012] The two power lines and two signal lines, which are covered by an insulation layer, are twisted together and then wrapped with a tape layer.

[0013] Two 16AWG power wires and two 28AWG signal wires constitute the conductor part of the composite cable, and both the power wires and signal wires are made of tin-plated copper.

[0024] In the diagram: 1. Power line; 2. Signal line; 3. Insulation layer; 4. Wrapping tape layer; 5. Filler material; 6. Sheath. Detailed Implementation

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] like Figure 1 As shown, the composite cable includes the following components:

[0027] It includes power line 1, signal line 2, insulation layer 3, wrapping layer 4, filler material 5, and sheath 6.

[0028] Signal line 2, two signal lines 2 are twisted together and connected;

[0029] Power line 1, the two power lines 1 are arranged outside the two twisted signal lines 2;

[0030] Insulation layer 3 covers the outside of the two power lines 1;

[0031] The wrapping layer 4 covers the outer periphery of the two power lines 1 after they are twisted together;

[0032] The filling material 5 is filled in the gap between the two power lines 1, the two twisted signal lines 2 and the wrapping layer 4 inside the wrapping layer 4;

[0033] Sheath 6 tightly covers the outer layer 4 of the strap.

[0034] In practice, the two power lines 1 and two signal lines 2, which are covered by the insulation layer 3, are twisted together and then wrapped with the wrapping layer 4. The two 16AWG power lines 1 and the two 28AWG signal lines 2 constitute the conductor part of the composite cable. Both the power lines 1 and the signal lines 2 are made of tin-plated copper. The conductor part uses 0.08mm tin-plated copper material in a twisted configuration. The two 16AWG wires are used to transmit power, and the pair of 28AWG wires are used to transmit signals.

[0035] Insulation layer 3 is made of ETFE (ethylene tetrafluoroethylene copolymer) with a thickness between 0.2 and 0.35 mm. In specific implementations, the design can be further customized according to actual needs to ensure sufficient insulation performance and torsional resistance.

[0036] The sheath 6 is made of polyurethane (PUR) material, with a thickness between 0.45 and 0.7 mm and a hardness between 80A and 90A. In specific implementations, the appropriate material can be selected based on the cable's operating environment and the robot's motion characteristics.

[0037] The total outer diameter and bending radius of the cable are optimized according to the design requirements of the humanoid robot to ensure a smooth cable layout inside the robot.

[0038] The tin-plated copper conductor ensures good conductivity and signal transmission quality, making it suitable for power and signal transmission. The ETFE insulation layer ensures safe use of the cable in harsh environments, extending its service life. The PUR sheath provides additional physical protection, reducing cable wear during robot movement.

[0039] This design gives the composite cable excellent insulation properties, high temperature resistance, chemical corrosion resistance and wear resistance, good abrasion resistance, tear resistance and flexibility, and can adapt to bending and twisting during robot movement.

[0040] Ultimately, the combined cable design meets the special requirements of humanoid robots for cables, improving the robot's reliability and stability.

[0041] In a specific implementation, the cable of this utility model is used as an electrical connection cable for a humanoid robot to transmit electrical signals and power for motion control of the humanoid robot. The test results are as follows.

[0042] Example: The composite cable is prepared according to the following steps:

[0043] 1) Twist the tinned copper conductors to 16AWG (power wire) and 28AWG (signal wire) specifications;

[0044] 2) Extruded ETFE insulation layer, with a controlled thickness of 0.25 mm;

[0045] 3) The power line and the twisted pair signal line are arranged coaxially, with a twist pitch of 15 mm for the power line and 8 mm for the signal line;

[0046] 4) Wrap an aramid fiber reinforcing layer around the stranded core;

[0047] 5) Extruded PUR sheath containing 3% carbon black, 0.6 mm thick.

[0048] Test results:

[0049] DC resistance: power line ≤13.2 Ω / km, signal line ≤227 Ω / km;

[0050] Withstand voltage: 3 kV / 5 min for power lines without breakdown;

[0051] Bending life: 6 million cycles (test standard UL 2556).

[0052] As can be seen from the results and parameters, the combined cable is particularly suitable for use with DC motors, ensuring the stability of power transmission and the accuracy of signal transmission.

[0053] The above embodiments are for illustrative purposes only and are not intended to limit the scope of this utility model. Those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope.
