Description

Technical Field

[0001] This utility model relates to the field of cable technology, specifically to a flame-retardant charging pile cable with high bending performance. Background Technology

[0002] Charging pile cables are cables specifically designed to connect charging piles and electric vehicles and provide power transmission. They are key components in the charging system and must meet special performance requirements such as high power transmission, wear resistance, high temperature resistance, and aging resistance. There are many types of cables, among which flame-retardant cables are widely used in industrial production. These cables can self-extinguish within a limited burning time. Their fundamental characteristic is that in the event of a fire, they limit the burning to a localized area, preventing it from spreading and protecting other equipment from greater losses. A flame-retardant cable is used in their application.

[0003] Based on this, a search on the patent website revealed that Chinese patent CN219085711U discloses a flame-retardant cable.

[0004] It is evident that the aforementioned patent application has shortcomings: the existing cables have relatively limited functions, and when used in high-temperature or high-pressure environments, they may be damaged, thus failing to adapt to different environments and greatly affecting their performance.

[0005] To address the aforementioned issues, a flame-retardant charging pile cable with high bending performance is proposed. Utility Model Content

[0006] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide a flame-retardant charging pile cable with high bending performance. By using this device, the problem of existing cables having relatively simple functions and being prone to damage when used in high-temperature or high-pressure environments is solved, thus making them unable to adapt to different environments and greatly affecting the performance of the cables.

[0007] The purpose of this utility model is achieved through the following technical solution: a flame-retardant charging pile cable with high bending performance, comprising a cable body jacket and a cable core disposed inside the cable body jacket, an outer flame-retardant layer fixedly connected to the inner side of the cable body jacket, an inner sleeve layer fixedly connected to the inner side of the outer flame-retardant layer, an inner sheath layer disposed inside the cable body jacket, and plugs fixedly connected to both ends of the cable body jacket, and a set of plugs having screws threadedly connected to the top.

[0008] Preferably, an inner flame-retardant layer is provided on the inner side of the inner sheath, and the inner flame-retardant layer is distributed on the outer side of the cable core.

[0009] The above-mentioned structural design, with the addition of an inner flame-retardant layer, gives the cable a certain degree of fire resistance, enabling it to adapt to different environments.

[0012] Preferably, an insulating layer is provided on the outer side of the inner sheath, and a cable spare core is provided on the inner side of the insulating layer. A fixing groove is provided on one side of one set of the plugs.

[0013] By adopting the above-described structure and adding an insulation layer, the insulation performance of the cable is further improved.

[0014] Preferably, one set of plugs has a fixing groove on one side, and the other set of plugs has a fixing block fixedly connected to one side, and multiple sets of fixing grooves and fixing blocks are provided.

[0015] The above-described structure, with its fixing slots and blocks, allows one set of plugs to be more easily connected to another set, improving efficiency.

[0016] Preferably, the fixing groove matches the fixing block, and a sealing gasket is fixedly connected to one side of the fixing block, and a plug body is fixedly connected to one side of the set of plugs.

[0017] The above-described structure, with the addition of a sealing gasket, provides a certain degree of sealing to the fixing groove, preventing external impurities from entering its interior.

[0018] Preferably, the other set of plugs has a socket on one side, and the plug body matches the socket.

[0019] The above-described structure, through the design of the plug-in interface and connector, ensures that there will be no other problems with the power supply of the two sets of cables, and saves manpower.

[0020] The beneficial effects of this utility model are as follows:

[0021] 1. This application achieves flame retardancy and pressure resistance for the cable by setting up an elastic layer, an inner sheath, and an insulation layer, thereby improving the cable's service life.

[0022] 2. This application achieves the connection of two sets of cables without complicated tools and steps by setting screws, plug interfaces, fixing slots and fixing blocks, which improves work efficiency and solves the problem that existing cables usually require tools such as wire strippers to connect, which makes it difficult for workers to connect cables quickly and affects their work efficiency.

[0028] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0029] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0030] Combination Figures 1-4 A flame-retardant charging pile cable with high bending performance includes a cable body jacket 1 and a cable core 2 disposed inside the cable body jacket 1. An outer flame-retardant layer 11 is fixedly connected to the inner side of the cable body jacket 1, and an inner sheath layer 12 is fixedly connected to the inner side of the outer flame-retardant layer 11. An inner sheath layer 13 is also disposed inside the cable body jacket 1. Plugs 14 are fixedly connected to both the left and right ends of the cable body jacket 1, and a screw 141 is threadedly connected to the top of a set of plugs 14.

[0031] The present invention will be further described below with reference to the embodiments.

[0032] Example 1

[0033] To address the issue that most existing cables have a simple structure and often lack resistance to flames and pressure, making them prone to damage during combustion, compression, or bending, thus affecting their performance, the following solution is disclosed. Please refer to the details. Figures 1-3 The inner sleeve 12 has an inner flame-retardant layer 121 on its inner side, and the inner flame-retardant layer 121 is distributed on the outer side of the cable core 2. The outer side of the inner sheath 13 is covered with an insulation layer 131, and the inner side of the insulation layer 131 is covered with a cable spare core 21. When the cable body sheath 1 is bent by external force, the cable body sheath 1 and the inner sleeve 12 are used. The cable body sheath 1 is made of elastic rubber material, while the inner sleeve 12 is made of polyurethane elastic material, which can prevent the cable from breaking during repeated bending. The outer flame-retardant layer 11 and the inner flame-retardant layer 12 are also used. The design of 121 enables the cable to have a certain fire-resistant function. The outer flame-retardant layer 11 and the inner flame-retardant layer 121 are composed of lightweight cross-linked polyolefin. When the external pressure is too high, the inner sheath 13 and the elastic layer 122 are provided. The inner sheath 13 is composed of polyvinyl chloride, which can resist the pressure. The elastic layer 122 is composed of silicone rubber, which can provide a certain buffering effect for the cable. This greatly improves the internal structure and protective strength of the cable without affecting the bending performance. It achieves the effect of flame retardancy and pressure resistance for the cable, and improves the service life of the cable.

[0034] Example 2

[0035] To address the issue that existing cable connections typically require tools like wire strippers, hindering workers' efficiency and preventing quick connections, the following solution is proposed. Please refer to the following for details. Figure 1 and Figure 4One set of plugs 14 has a fixing groove 142 on one side, and the other set of plugs 14 has a fixing block 143 fixedly connected to one side. Multiple sets of fixing grooves 142 and fixing blocks 143 are provided. The fixing grooves 142 and fixing blocks 143 are matched, and a sealing gasket 144 is fixedly connected to one side of the fixing block 143. One set of plugs 14 has a plug body 15 fixedly connected to one side, and the other set of plugs 14 has a plug interface 151 on one side. The plug body 15 matches the plug interface 151. When it is necessary to connect the two sets of cables, the plug 14 of one set is aligned with the plug of the other set. The plug 14 is inserted, and the fixing block 143 is moved into the fixing slot 142. At this time, the plug body 15 contacts the plug interface 151, which enables the two sets of cables to be energized. Then, the screw 141 is turned, and the screw 141 is fixed to the fixing block 143 to prevent the plug 14 of one set from falling off the plug 14 of the other set. When it is necessary to loosen, the screw 141 is turned in the opposite direction, so that the plug 14 of one set is disconnected from the plug 14 of the other set. This realizes the connection of two sets of cables without complicated tools and steps, improving work efficiency.

[0036] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this utility model are within the protection scope of this utility model.
