[0015] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0016] A specific embodiment of the present invention is as Figure 1 and Figure 2 shown:

[0017] Conductor 1: The main conductor is made of 0.20 ± 0.008 mm bare copper wire in regular stranding.

[0018] Insulating layer 2: Made of silicone rubber material at -50~200 °C. Silicone rubber has good softness and good heat dissipation performance, and is suitable for fixed bending laying in the vehicle for easy installation. In extremely harsh weather environments, it can also maintain good insulation performance.

[0019] Fixing wire: It is divided into longitudinal and transverse fixing wires. The longitudinal one adopts a symmetric semi-circular (semi-circular diameter R) shear type, as Figure 4 shown; the transverse fixing wire adopts a V-shaped (angle T) shear type, as Figure 3 shown. The longitudinal metal wires are all made of low-carbon steel wires, which have good plasticity, small deformation resistance, high strength, corrosion resistance, rain resistance, and at the same time have good toughness and excellent heat dissipation performance.

[0020] Longitudinal fixing wire 4: Each fixing wire has semi-circular shapes on both the front and back. Its operation is similar to that of the transverse one, except that the bending point can be at any point on the inner arc surface of the semi-circle, enabling bending from 0 to 180 degrees.

[0021] Transverse fixing wire 3: Each fixing wire has a certain number of positive and negative V-shaped patterns on it. The V-shaped patterns have a certain degree. When bent, the V-shaped patterns on the bending surface can close, enabling a bending degree of 30 to 60 degrees, and the V-shaped patterns on the opposite side open. This structure can achieve bending within a certain degree, and the bending point can be fixed at the V-shaped part. It can also achieve multi-point bending.

[0022] The dimensions of the transverse fixing wire and the longitudinal fixing wire are as follows in the table:

[0023] Conductor cross-sectional area Longitudinal fixing wire diameter Transverse fixing wire diameter Angle T Radius R 10~25mm² 5.0mm 1.5 mm 30° 2.00mm 26~50mm² 9.0mm 2.5 mm 35° 3.20mm 51~70mm² 12.0mm 4 mm 45° 4.50mm 71~95mm² 15.0mm 6 mm 60° 6.00mm

[0024] Fastening layer 5: A -40 to 150 °C thermoplastic polyester elastomer (TPEE) semi-sleeve is extruded outside the insulation and the fixing wire. This extrusion method can play a role in relieving stress during folding and shaping. This material has excellent anti-bending fatigue performance, good tear resistance and wear resistance, outstanding chemical resistance and weather resistance, prominent mechanical strength, excellent resilience, and a wide operating temperature range.
