The cable body is provided with a positive conductor and a negative conductor. An insulation layer is provided around the positive conductor and the negative conductor. A cooling layer is provided around the insulation layer. A flow channel for coolant to pass through is formed between the cooling layer and the insulation layer. The charging head is provided with a positive cavity, a negative cavity and an isolation cavity. The isolation cavity is connected to the positive cavity and the isolation cavity is connected to the negative cavity. A first one-way valve is provided between the isolation cavity and the positive cavity. A second one-way valve is provided between the isolation cavity and the negative cavity.

[0004] During the charging process, if the charging pile cable needs to be moved, it often involves dragging and pulling. This frequent dragging will cause the cable to experience continuous friction at the contact point with the ground. Over time, the cable surface is easily worn, affecting its subsequent durability and performance, and adversely affecting the long-term application of the cable. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a charging pile cable that features the ability to install an appropriate number of protective mechanisms to protect the cable based on its length, and the ability to replace the protective sleeve individually if it is damaged.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a charging pile cable, comprising a cable for transmitting electrical energy from the charging pile to the battery pack of an electric vehicle, wherein a protective mechanism is provided on the cable for protecting the cable, the protective mechanism comprising:

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-6 This utility model provides a charging pile cable technical solution: a charging pile cable, including a cable 1 for transmitting electrical energy from the charging pile to the battery pack of an electric vehicle, wherein a protective mechanism 2 is provided on the cable 1 for protecting the cable 1, and the protective mechanism 2 includes:

[0029] The protective component 21 includes several interconnected protective sleeves 211 sleeved and installed on the cable 1, several plugs 212 fixed on the outer wall of the front end of the protective sleeve 211 and distributed circumferentially, several slots 213 distributed circumferentially on the inner wall of the rear end of the protective sleeve 211, a slot 214 opened on one side inside the slot 213, several mounting grooves 215 opened on the outer wall of the protective sleeve 211, and grooves 216 opened on both sides inside the mounting grooves 215.

[0030] Abrasion-resistant component 22 is disposed on protective component 21 and is used to contact the ground.

[0031] In this embodiment, multiple protective sleeves 211 are installed on the cable 1. The rear protective sleeve 211 is inserted into the slot 213 of the front protective sleeve 211 through a plug 212. The rear protective sleeve 211 is then rotated slightly so that the plug 212 on the rear protective sleeve 211 engages with the slot 214 on the front protective sleeve 211, thereby connecting the adjacent protective sleeves 211. This allows for the installation of an appropriate number of protective mechanisms 2 to protect the cable 1 according to its length. Furthermore, the protective sleeves 211 can be replaced individually when damaged during daily use.

[0032] Specifically, the wear-resistant component 22 includes a wear-resistant strip 221 inserted into the mounting slot 215.

[0033] In this embodiment, when the protective mechanism 2 is installed on the cable 1 and comes into contact with the ground during dragging, a portion of the wear-resistant component 22 can come into contact with the ground, thereby reducing the wear on the protective sleeve 211. The wear-resistant component 22 can be replaced separately after it wears out.

[0034] Specifically, the wear-resistant component 22 also includes protrusions 222 fixed at both ends of the wear-resistant strip 221, and the protrusions 222 cooperate with the grooves 216.

[0035] In this embodiment, when the wear-resistant strip 221 is inserted into the mounting groove 215, the protrusion 222 is engaged in the groove 216, thereby preventing the wear-resistant component 22 from loosening from the protective component 21; and when adjacent protective components 21 are connected to each other, the wear-resistant component 22 on each protective component 21 can be fixed.

[0036] Specifically, the wear-resistant component 22 also includes several notches 223 that are equidistantly distributed at the outer end of the wear-resistant strip 221.

[0037] In this embodiment, without affecting the contact between the wear-resistant strip 221 and the ground, the material used in the wear-resistant strip 221 can be reduced by opening multiple notches 223 on the wear-resistant strip 221, thereby reducing the cost.

[0038] Specifically, the protective mechanism 2 also includes a clamp 23 fitted onto the protective component 21 and used to fix the protective component 21 to the cable 1.

[0039] In this embodiment, multiple protective components 21 are fitted onto the cable 1, and adjacent protective components 21 are connected to each other. Then, clamps 23 are fitted onto the frontmost and rearmost protective components 21, and the frontmost and rearmost protective components 21 are fixed onto the cable 1 by the clamps 23, thereby fixing multiple interconnected protective components 21 onto the cable 1.

[0040] Specifically, the cable 1 includes a cable core 12 fixed inside the insulation layer 11, a filling layer 13 filling the space between the insulation layer 11 and the cable core 12, and a shielding layer 14 wrapped around the outside of the filling layer 13.

[0041] Specifically, the cable 1 also includes an oxygen barrier layer 15 wrapped around the shielding layer 14, and a sheath 16 wrapped around the oxygen barrier layer 15.

[0042] In this embodiment, the oxygen barrier layer 15 prevents oxygen from entering the interior of the cable 1, thereby significantly enhancing the flame retardant performance of the cable 1.

[0043] The working principle and usage process of this utility model are as follows: First, multiple protective sleeves 211 are installed on the cable 1. The rear protective sleeve 211 is inserted into the slot 213 of the front protective sleeve 211 through a plug 212. Then, the rear protective sleeve 211 is rotated slightly so that the plug 212 on the rear protective sleeve 211 engages with the slot 214 on the front protective sleeve 211, thereby connecting the adjacent protective sleeves 211. Next, clamps 23 are fitted on the frontmost and rearmost protective components 21, and the frontmost and rearmost protective components 21 are fixed to the cable 1 through the clamps 23, thereby fixing multiple interconnected protective components 21 together on the cable 1. This achieves the installation of an appropriate number of protective mechanisms 2 to protect the cable 1 according to its length. Furthermore, the protective sleeve 211 can be replaced individually when it is damaged during daily use. During dragging, when it comes into contact with the ground, a portion of the wear-resistant component 22 can contact the ground, thereby reducing the wear on the protective sleeve 211. The wear-resistant component 22 can also be replaced individually when it is worn.
