Description

Technical Field

[0001] The present invention relates to the field of cables, and more particularly to cables stacked one above the other. Background Art

[0002] Cables are commonly used conductors in daily life, transmitting electricity or information from one place to another. At present, with the development of society, electricity consumption has also increased, and the requirements for cables have become higher and higher. When a certain load current passes through the cable, it will definitely heat up. As the load current increases, the surface temperature of the cable becomes higher. If the current carrying capacity of the wire and cable exceeds its maximum carrying capacity, it may cause a fire due to untimely heat dissipation, resulting in loss of life and property.

[0003] Existing stacked cables have more cable cores, which will increase their heat generation. Due to their stacked structure, heat will accumulate, which will prevent the heat from being dissipated in time, thus easily causing safety accidents. Utility Model Content

A cavity is opened inside the protective layer, and the inner wall of the cavity is fixedly connected to a braided layer. The three conductive components are all arranged inside the braided layer, and the heat dissipation component is in contact with the braided layer.

[0007] By adopting the above technical solution, the three conductive components are arranged inside the protective layer for protection, and a braided layer is arranged between the protective layer and the conductive components. The arrangement of the braided layer is convenient for protecting the conductive components while facilitating the cooperation with the heat dissipation components to assist the cable in heat dissipation.

[0008] The conductive component comprises a heat-conducting insulating layer, and a cable core is installed inside the heat-conducting insulating layer.

[0010] The heat-conducting insulating layer is in contact with the braided layer, and the braided layer is formed by braiding a plurality of copper wires.

[0011] By adopting the above technical solution, the heat generated by the cable core is transferred to the braided layer through the heat-conducting insulating layer, and the braided layer improves the efficiency of heat transfer by weaving copper wires.

[0012] The heat dissipation assembly includes a heat dissipation sleeve, and a plurality of heat conducting sheets are fixedly connected to the inner wall of the heat dissipation sleeve, and a plurality of heat dissipation grooves distributed at equal distances are opened on the outer wall of the heat dissipation sleeve.

[0013] By adopting the above technical solution, the contact area between the heat dissipation sleeve and the air is increased by the heat dissipation grooves on the outer wall of the heat dissipation sleeve, and the arrangement of the heat conducting sheet facilitates the transfer of heat from the cable to the heat dissipation sleeve.

[0014] The heat conducting sheet is embedded in the protective layer, and one end of the heat conducting sheet is fixedly connected to the braided layer.

[0015] By adopting the above technical solution, the heat conducting sheet and the braided layer are connected, and the braided layer absorbs the heat of the cable core and transfers it to the heat dissipation sleeve through the heat conducting sheet.

[0016] The protective layer includes a wear-resistant layer, and the inner wall of the wear-resistant layer is fixedly connected to the waterproof layer, the inner wall of the waterproof layer is fixedly connected to the protective layer, and the inner wall of the protective layer is fixedly connected to the insulating layer.

[0017] By adopting the above technical solution, the wear resistance of the cable is improved by setting the wear-resistant layer in the protective layer, the waterproof layer is conveniently set to improve the waterproof performance of the cable, and the insulating layer is set to improve the insulation performance of the cable.

[0018] The insulating layer is in contact with the braided layer, and the outsides of the copper wires in the braided layer are coated with insulating paint.

[0019] By adopting the above technical solution, the insulation performance of the cable is improved by coating the copper wires in the braided layer with insulating varnish.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0031] Reference Figure 2-3 A cavity is provided inside the protective layer 1, and a braided layer 7 is fixedly connected to the inner wall of the cavity. The setting of the cavity facilitates the installation of the braided layer 7. The three conductive components 3 are all arranged inside the braided layer 7. The heat dissipation component 2 is in contact with the braided layer 7. The braided layer 7 protects the conductive component 3, thereby improving the service life of the conductive component 3. The thermal insulation layer 8 is in contact with the braided layer 7. The braided layer 7 is formed by weaving multiple copper wires. The braided layer 7 woven with copper wires facilitates the heat dissipation efficiency of the auxiliary conductive component 3.

[0032] Reference Figure 2-3 The conductive component 3 of the main body of the cable includes a thermally conductive insulating layer 8, and a cable core 9 is installed inside the thermally conductive insulating layer 8. The cable core 9 is wrapped by the thermally conductive insulating layer 8. The setting of the thermally conductive insulating layer 8 protects the cable core 9 while facilitating the timely discharge of the heat generated by the cable core 9.

[0033] Reference Figure 2-3 The heat dissipation component 2 includes a heat dissipation sleeve 4, and the inner wall of the heat dissipation sleeve 4 is fixedly connected to a plurality of heat conductive plates 6. The outer wall of the heat dissipation sleeve 4 is provided with a plurality of heat dissipation grooves 5 distributed at equal distances. The heat conductive plates 6 are embedded in the protective layer 1, and one end of the heat conductive plates 6 is fixedly connected to the braided layer 7.

[0034] When in use, the heat conducting sheet 6 and the braided layer 7 are connected. The braided layer 7 absorbs the heat of the cable core 9 and transfers it to the heat dissipation sleeve 4 through the heat conducting sheet 6. The heat dissipation groove 5 on the outer wall of the heat dissipation sleeve 4 increases the contact area between the heat dissipation sleeve 4 and the air. The setting of the heat conducting sheet 6 facilitates the transfer of heat from the cable to the heat dissipation sleeve 4.

[0035] Reference Figure 4 The protective layer 1 of the protective cable includes a wear-resistant layer 10, and the inner wall of the wear-resistant layer 10 is fixedly connected to a waterproof layer 11, the inner wall of the waterproof layer 11 is fixedly connected to a protective layer 12, and the inner wall of the protective layer 12 is fixedly connected to an insulating layer 13. The insulating layer 13 is in contact with the braided layer 7, and the outside of the copper wire in the braided layer 7 is coated with insulating paint.

[0036] When in use, the wear resistance of the cable is improved by setting the wear-resistant layer 10 in the protective layer 1, the waterproof layer 11 is conveniently set to improve the waterproof performance of the cable, the insulating layer 13 is set to improve the insulation performance of the cable, and the copper wire in the braided layer 7 is coated with insulating paint, thereby improving the insulation performance of the cable.

[0037] The implementation principle of the upper and lower stacked cables in the embodiment of the present application is: when in use, when the cable is working, a large current passes through the three conductive components 3 at the same time, which directly causes the cable core 9 in the conductive component 3 to generate a large amount of heat. The heat generated by the conductive component 3 is absorbed by the braided layer 7, and the braided layer 7 transfers the heat to the heat dissipation sleeve 4 through the heat conductive sheet 6. A plurality of heat dissipation grooves 5 are provided on the heat dissipation sleeve 4. The setting of the heat dissipation grooves 5 increases the contact area between the heat dissipation sleeve 4 and the air, thereby expanding the heat dissipation efficiency of the heat dissipation sleeve 4, and improves the heat dissipation efficiency of the cable through the multiple heat dissipation components 2 on the cable.
