Figure 1 When observing, the observer's left front side is designated as "front," the observer's right rear side as "rear," the observer's left rear side as "left," the observer's right front side as "right," the observer's top as "up," and the observer's bottom as "down." It should be noted that the terms "front end," "rear end," "left side," "right side," "middle," "above," and "below" in this text indicate orientations or positional relationships based on the accompanying drawings. These are merely for the purpose of clearly describing the present invention and do not indicate or imply that the structure or component referred to must have a specific orientation or be constructed in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," "third," and "fourth" are used only for the purpose of clarity or simplification of description and should not be construed as indicating or implying relative importance or quantity.

[0021] In the prior art, the flexibility and bendability of cables are only improved by insulation and sheath materials. However, this invention increases the cable's texture, making it easier to bend and greatly increasing its service life. At the same time, the cable conductor, signal core, and control core use a sixth type of conductor, thus making the cable easy to bend.

[0022] See Figure 1 , Figure 2 This utility model provides an easy-to-bend AC charging gun cable, including a cable core and an outer sheath that wraps around the cable core. The cable core includes a cable conductor 1, a signal line assembly 2, and a control line assembly 3. An outer protective layer 6 is provided in the outer sheath, and the outer surface of the outer protective layer 6 is provided with texture. When the cable is bent, the cable can bend along the texture of the outer protective layer 6.

[0023] Specifically, the number of cable conductors 1 is 3; the three cable conductors 1 are symmetrically arranged at the center of the cable core, forming a triangular shape. Specifically, the signal line assembly 2 and the control line assembly 3 are arranged between the cable conductors 1 and the outer sheath.

[0024] As a preferred embodiment of this utility model, see [link to relevant documentation]. Figure 2 The texture is a continuous thread provided on the outer protective layer 6. The continuous thread is a concave pattern. The continuous thread spirals upward on the outer protective layer 6 and is an unbroken line.

[0025] Specifically, cable conductor 1 is further provided with a conductor insulation layer, which wraps around the outer layer of cable conductor 1; cable conductor 1 is made of stranded monofilaments of the sixth type of soft conductor in GB / T 3956 standard; the conductor insulation layer is an ethylene propylene rubber layer. Specifically, signal line assembly 2 includes a signal wire core and a signal wire insulation layer wrapping the signal wire core; the signal wire core is made of stranded monofilaments of the sixth type of soft conductor in GB / T 3956 standard, and the signal wire insulation layer is an ethylene propylene rubber layer. Specifically, control line assembly 3 includes a control wire core and a control wire insulation layer wrapping the control wire core; the control wire core is made of stranded monofilaments of the sixth type of soft conductor in GB / T 3956 standard, and the control wire insulation layer is an ethylene propylene rubber layer.

[0026] The cable conductors 1, signal cores, and control cores use the sixth type of soft conductor monofilament in GB / T 3956 standard. These monofilaments are regularly twisted into a single strand, and then each strand is re-twisted, resulting in excellent bending performance, no loosening, more stable production in subsequent processes, and superior products.

[0027] The insulation layers of the cable conductors, signal lines, and control lines are made of high-quality ethylene propylene rubber. This material has excellent insulation and mechanical properties, as well as corrosion resistance, cold resistance, high temperature resistance, oil resistance, and water resistance. As a type of rubber, it also has good flexibility and is easy to bend.

[0028] Specifically, the cable core also includes filler 4, which is placed in the gaps between the wires in the cable core to fill and fix them. Filler 4 is PP filler rope. The use of PP filler rope serves to fill and round the cable.

[0029] Specifically, the outer sheath consists of a wrapping and fixing layer 5 and an outer protective layer 6, arranged from the inside out. Specifically, the wrapping and fixing layer 5 is a non-woven fabric layer, and the outer protective layer 6 is a TPU layer.

[0030] Non-woven fabric is used for wrapping, and the three cable conductors, one signal wire core, and one control wire core are twisted into one cable core for wrapping and fixing.

[0031] The outer protective layer 6 is a TPU layer, which has a tensile strength of up to 20 N / mm², an elongation of up to 300%, and is also wear-resistant, aging-resistant, hydrolysis-resistant, and waterproof. After extrusion, before cooling, the outer protective layer 6 is molded to create a corrugated texture, allowing the cable to bend according to the texture during bending.

[0032] This utility model relates to an easily bendable AC charging gun cable, characterized by its excellent bending performance. During bending, the cable can bend according to the texture of the outer protective layer. The use of ethylene propylene rubber as the insulation layer provides excellent bending properties, while TPU as the outer protective layer material offers wear resistance, water resistance, and anti-aging effects, allowing for long-term use and increasing the cable's lifespan. The advantages of the cable are as follows: 1. The cable conductors 1 (signal and control wires) use a sixth type of conductor, with thin single filaments and good bending performance; 2. The insulation layers of the cable conductors, signal wires, and control wires are made of ethylene propylene rubber, giving the cable excellent flexibility; 3. The outer protective layer 6 uses TPU material, which is fire-resistant, waterproof, and has superior mechanical properties compared to other common materials, increasing the cable's lifespan; 4. The outer protective layer 6 features a threaded texture, allowing the cable to bend according to the texture during bending, achieving a good bending effect, enhancing the cable's bending performance, and increasing its lifespan.

[0033] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
