Technical Field

[0002] Liquid-cooled charging gun cables are new energy vehicle charging cables that achieve efficient heat dissipation through built-in liquid circulation, primarily used to improve charging efficiency and ensure safety. Through a coolant circulation system, the liquid-cooled charging gun cable effectively transfers heat during charging, preventing overheating that could lead to performance degradation or safety hazards.

[0003] In existing technologies, such as Chinese Patent No. CN222762696U, an 800A liquid-cooled integrated cable for a charging gun is described. This cable has a DC+ liquid-cooled charging wire, a DC- liquid-cooled charging wire, a grounding wire, and several auxiliary wires wrapped inside its insulating outer sheath. Coolant channels and conductors are provided within the DC+ and DC- liquid-cooled charging wires, connecting the liquid-cooled terminals and liquid-cooled electrodes. There are two DC+ and two DC- liquid-cooled charging wires, and the two coolant channels within the two DC+ or two DC- liquid-cooled charging wires are connected through the liquid-cooled terminals, forming a cooling circuit. This liquid-cooled integrated cable significantly reduces the wire diameter to only 26mm while safely carrying 800A of current, with a bending radius within 200mm. The optimized layout of the conductors not only reduces gaps and increases the roundness of the cable but also eliminates anisotropy in the bending direction. This liquid-cooled integrated cable is thin, lightweight, and flexible, significantly improving the flexibility and user experience of charging operations. A patent application for the same invention was filed on the same day.

[0004] While the above solution has the advantages mentioned above, its disadvantages are that the design lacks partitioning of the wiring. After long-term use, the internal wiring will become tangled and difficult to manage, increasing the difficulty of maintenance. In addition, the design lacks waterproof and anti-static features for the protective cover, posing a significant safety hazard during charging. Utility Model Content

[0013] As a preferred embodiment, the slot one is formed on one side of the curved panel.

[0014] The technical effect of adopting the above-mentioned further solution is that the slot provides displacement space for the pull plate.

[0015] In a preferred embodiment, the partitioning component further includes: The second slot is formed at the bottom of the inner wall of the first slot; The second slot penetrates the curved panel and corresponds to the positioning hole.

[0016] The technical effect of adopting the above-mentioned further solution is that the second slot provides displacement space for the limiting post, so that the limiting post can be smoothly embedded in the positioning hole to fix the position of the curved panel.

[0017] In a preferred embodiment, a pull plate is slidably embedded in the slot, and a limit post is installed on one side of the pull plate.

[0018] The technical effect of adopting the above-mentioned further solution is that the displacement state of the limiting column is controlled by the pull plate.

[0025] Compared with the prior art, the advantages and positive effects of this utility model are as follows: This invention places a central ring inside a protective sleeve and uses multiple T-shaped clips to partition different circuits. Pulling the pull plate upwards along the inner wall of slot one causes the spring to be compressed, displacing the limiting post to the same side and pulling it out of the positioning hole. The T-shaped clips are then manually moved, and when two T-shaped clips close together, the pull plate is released. The elasticity of the spring pushes the limiting post into the positioning hole, thus fixing the T-shaped clips in place. In this design, the partitioning assembly divides the circuits inside the protective sleeve into sections, and the size of each section can be manually adjusted to fully utilize the internal space for easier maintenance later.

[0026] This invention features a flame-retardant layer made of halogen-free flame-retardant polyolefin material containing a special flame retardant. It is halogen-free, low-smoke, and non-toxic.

The waterproof layer employs a waterproof and breathable GL-series membrane material, which allows for ventilation and heat dissipation through its microporous structure and possesses extremely high waterproofness, preventing external water from entering the protective sleeve. This design utilizes the combined action of multiple materials to effectively prevent external water from entering the protective sleeve while simultaneously avoiding internal current leakage.

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. Example

[0030] Please see Figures 1-6This embodiment provides a liquid-cooled charging gun cable, the specific concept of which is as follows: A liquid-cooled charging gun cable includes a protective sleeve 1, and the liquid-cooled charging gun cable also includes a central ring 101 and a partitioning assembly.

[0031] The central ring 101, which serves as the center, is located inside the protective sleeve 1, and one end of it can be connected to the inside of the charging gun.

[0032] Meanwhile, the partitioning component is located on the central ring 101 to partition and plan different types of lines within the protective sleeve 1.

[0033] As examples, in this embodiment, the partitioning component includes: an annular groove 102, multiple positioning holes 103, multiple curved panels 2, multiple T-shaped buckles 201, slot one 202, slot two 203, pull plate 204, and spring 206.

[0034] The annular groove 102, which serves a spatial function, is formed on the protective sleeve 1.

[0035] To secure the T-shaped buckle 201, multiple positioning holes 103 are provided on the inner wall of the annular groove 102.

[0036] Meanwhile, multiple curved panels 2 that serve a sliding function are slidably embedded in the annular groove 102.

[0037] In addition, multiple T-shaped clips 201 are installed on the top of the curved panel 2.

[0038] It should be noted that each T-shaped buckle 201 has a notch on one side of its top, which can be matched with the top side of another T-shaped buckle 201.

[0039] In this design, a slot 202 is also provided on one side of the curved panel 2.

[0040] Among them, the second slot 203, which serves as the track, is opened at the bottom of the inner wall of the first slot 202.

[0041] It should be added that the second slot 203 penetrates the curved panel 2 and corresponds to the positioning hole 103.

[0042] Furthermore, the pull plate 204, which is used for pulling action, is slidably embedded in the slot 202, and a limit post 205 is installed on one side of the pull plate 204.

[0043] In addition, a spring 206 that provides elasticity is installed on the other side of the pull plate 204.

[0044] It should be noted that the limiting post 205 is embedded in the second slot 203 and can fit with the positioning hole 103, and the other end of the spring 206 is connected to the top of the first slot 202.

[0045] In this embodiment, the central ring 101 is first placed inside the protective sleeve 1, and multiple T-shaped buckles 201 are used to divide different circuits. Then, the pull plate 204 is pulled upward along the inner wall of the slot 202. The spring 206 is pressed by the pull plate 204, and the limiting post 205 is moved to the same side under the action of the pull plate 204 and pulled out from the positioning hole 103. The T-shaped buckles 201 are manually moved, and when the two T-shaped buckles 201 are combined, the pull plate 204 is released. Finally, the elastic action of the spring 206 is used to push the limiting post 205 into the positioning hole 103, thus completing the position fixation of the T-shaped buckles 201. Example

[0046] Please see Figures 1-6 Based on Embodiment 1, this embodiment provides a liquid-cooled charging gun cable, the specific idea of ​​which is as follows: the liquid-cooled charging gun cable also includes a protective component, which is located inside the protective sleeve, and is used to prevent internal current leakage and to resist external water flow.

[0047] As examples, in this embodiment, the protective components include: a flame-retardant layer 3, an antistatic layer 301, an insulating layer 302, and two waterproof layers 303.

[0048] To prevent the interior from being affected by unexpected high temperatures from the outside, a flame-retardant layer 3 is provided inside the protective sleeve 1, close to the outer layer.

[0049] The partition is made of halogen-free flame-retardant polyolefin material, which contains special flame retardants, is low in smoke and non-toxic, and can effectively insulate against external high temperatures to prevent safety accidents caused by heat entering the protective sleeve 1.

[0050] To effectively prevent internal static electricity, an antistatic layer 301 is provided inside the protective sleeve 1 near the middle layer.

[0051] In this partition, Kevlar tensile fiber material is used, which has the characteristics of high strength, so it is placed in the middle layer, and its surface resistivity was measured to be 10 under experimental conditions. 6 Ω can effectively resist electrostatic current.

[0052] To prevent leakage of induced current between internal circuits, an insulating layer 302 is provided as the innermost layer inside the protective sleeve 1.

[0053] YJ-type cross-linked polyolefin material was used in this partition layer. Its dielectric strength was measured to be greater than 30kV / mm in experiments, so it can be used as an insulating core layer to prevent internal current leakage.

[0054] In this design, two waterproof layers 303 are also provided on both sides of the antistatic layer 301.

[0055] The two waterproof layers 303 use waterproof and breathable membrane GL series material, which has extremely high waterproof properties, with an air permeability of ≥5000g / m²·24h and can withstand water pressure of over 50kPa, thus having highly efficient waterproof properties.

[0056] Working principle: When it is necessary to partition the wiring inside the protective sleeve 1, the central ring 101 can be placed inside the protective sleeve 1, and different wiring can be manually placed between the two T-shaped clips 201. When it is necessary to adjust the partition, the pull plate 204 can be manually pulled to move upward along the inner wall of the slot 202. In this movement state, the spring 206 is in a compressed state, and the limiting post 205 moves upward in a straight line under the drive of the pull plate 204 and disengages from the positioning hole 103. At this time, the T-shaped clips 201 can be moved so that the curved panel 2 slides in the annular groove 102. When the two T-shaped clips 201 merge, the pull plate 204 is released, and the spring 206 in a compressed state uses its own elasticity to push the limiting post 205 into the corresponding positioning hole 103, thus fixing the position of the T-shaped clips 201. At this time, the two T-shaped clips 201 merge one partition and expand the space of the remaining partitions.

[0057] In the design of the protective sleeve 1, the main material of the flame-retardant layer 3 is halogen-free flame-retardant polyolefin, which is a polyolefin material made by adding special flame retardants. It does not contain halogen elements and has the characteristics of low smoke and non-toxicity. The main material of the antistatic layer 301 is Kevlar tensile fiber, which has permanent antistatic properties. This property comes from its poly(p-phenylene terephthalamide) molecular chain structure, which can effectively eliminate electrostatic interference. In the innermost insulating layer 302 of the protective sleeve 1, the main material is YJ-type cross-linked polyolefin, which has the characteristics of impact resistance, corrosion resistance, and excellent insulation performance. It is mainly used as the core insulation layer of wires and cables and is suitable for power transmission and signal transmission scenarios. The waterproof layer 303 mainly uses waterproof and breathable membrane GL series material, which achieves the effects of breathability and heat dissipation through the polymer microporous structure. It is suitable for scenarios such as charging gun sockets and can quickly balance the pressure difference between the inside and outside of the equipment.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art.
