The welding points 24 facilitate the connection between the metal strips 23 on two adjacent protective sleeves 2. While the metal strips 23 connect the two adjacent protective sleeves 2, they also support the protective sleeves 2, which can improve the strength of the protective sleeves 2. The metal strips 23 also support the outer sheath 6, limit the bending angle of the cable, and reduce the probability of damage to the cable due to excessive bending. The setting of the metal strips 23 is also conducive to the connection between the protective sleeve 2 and external supporting components such as the bracket for installing the cable.

[0022] Among them, both ends of the protective sleeve 2 are provided with a plurality of tear lines 22 distributed in a ring shape around the center of the circle. A plurality of tear bodies are formed on the protective sleeve 2 through the tear lines 22. The tear bodies are wrapped around the metal strip 23. The existence of the tear lines 22 enables the tear bodies to be torn off from the protective sleeve 2, which is conducive to peeling the metal strip 23 out of the tear bodies, changing the length of the exposed metal strip 23, making the connection of the protective sleeve 2 more flexible, and not easy to damage the outer sheath 6 when peeling off the metal strip 23.

[0023] A heat dissipation channel 3 is formed between the inner wall of the protective sleeve 2 and the outer wall of the outer sleeve 6. The space between the two protective sleeves 2 is separated by a metal strip 23 to form a heat dissipation port connected to the heat dissipation channel 3. The heat dissipation channel 3 and the heat dissipation port are beneficial to the heat dissipation of the cable.

[0024] The protection sleeve 2 is further provided with a heat dissipation hole 21 connected with the heat dissipation channel 3 . There are a plurality of heat dissipation holes 21 . The provision of the heat dissipation holes 21 can further improve the heat dissipation capacity of the cable.

There is no specific limitation on the materials for making the inner elastic support layer 63 and the outer elastic support layer 61, and the inner elastic support layer 63 and the outer elastic support layer 61 can use the same material or different materials. For example, the inner elastic support layer 63 can be made of insulating silicone rubber material, and the outer elastic support layer 61 can be made of TPU material.

[0026] Among them, the wire core 1 includes a metal conductor 11, and the metal conductor 11 is wrapped with an insulating layer 12. The metal conductor 11 is generally a copper core.
