Steel wires are interlaced inside the reinforcing layer 107, and a friction layer 108 is provided on the outer side of the reinforcing layer 107. The interlaced steel wires inside the reinforcing layer 107 have high tensile strength, effectively bearing and dispersing external tensile force, thereby protecting the internal structure of the cable assembly 1, improving the tensile performance of the cable assembly 1, reducing damage to the internal structure of the cable assembly 1 caused by tensile force, extending the service life of the cable assembly 1, reducing the frequency and cost of replacing the cable assembly 1, and ensuring the continuous and stable power transmission of the cable assembly 1, thus ensuring the normal use of the cable assembly 1.

[0022] like Figure 4As shown, a filling layer 103 is provided on the outer side of the inner sheath 102. Multiple heat sinks 104 are evenly distributed on the outer side of the filling layer 103. Through holes are opened in the interior of the heat sinks 104.

The shielding layer 105 helps to block the influence of external electromagnetic fields on the internal transmission signals of the cable assembly 1, prevents the high-frequency signals inside the cable assembly 1 from radiating electromagnetic energy outward, avoids interference with nearby electronic equipment, and reduces energy waste. The outer sheath 106 helps to protect the cable assembly 1 from damage such as friction and scratches, and extends its service life.

[0027] The usage and working principle of this device are as follows: Heat sinks 104 are evenly distributed on the outside of the filling layer 103, creating a cavity inside the cable assembly to transfer the heat generated by the cable assembly 1, accelerating heat dissipation. The shielding layer 105 acts as a barrier to block external electromagnetic fields from affecting the internal signal transmission of the cable assembly 1. The outer sheath 106 protects the cable assembly 1 from damage such as friction and scratches, extending its service life. The reinforcing layer 107 has interlaced steel wires with high tensile strength, effectively bearing and dispersing external tension, thus protecting the internal structure of the cable assembly 1 and improving its tensile performance. Protrusions 109, in conjunction with friction pads 110, are distributed on the outside of the friction layer 108, increasing the friction between the cable assembly 1 and external objects, preventing the cable assembly 1 from sliding in the laying environment, ensuring accurate laying position, and reducing damage caused by shaking or collisions with other objects.
