Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a fireproof and tensile-resistant cable. Background Art

[0002] Cable is a device for transmitting electric energy or signals, usually composed of several or several groups of wires. Aluminum alloy cable is a new type of power cable with improved bending performance, creep resistance and corrosion resistance, which can ensure that the cable maintains continuous performance stability when overloaded and overheated for a long time, and its application is gradually becoming more and more widespread.

[0003] However, the current cables still use a close-fitting distribution method for the multiple groups of cores inside. The cores affect each other. When a group of cores has a safety problem, the other cores are interfered with each other. The fire safety performance is insufficient and there are certain limitations in use. In order to have fire-resistant properties, a flame-retardant layer is usually provided. During use, the cable will be stretched and stressed, causing the material to break and the fire-resistant effect to be reduced. Utility Model Content

The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0024] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed at will, and the component layout may also be more complicated.

[0025] Example 1

[0026] like Figures 1-2 As shown:

[0027] A fireproof and tensile-resistant cable, comprising

[0028] The battery cell 1 comprises a central battery cell 11 and a peripheral battery cell 12; the central battery cell 11 is located at the center; the peripheral battery cell 12 is wrapped around the central battery cell 11; a fireproof layer 2 is arranged outside the central battery cell 11 and the peripheral battery cell 12; the fireproof layer 2 is arranged as a mica tape. Mica tape is a fire-resistant insulating material, mainly used for insulation of motors and cables. It has excellent high temperature resistance and combustion resistance, and can basically not produce harmful smoke when burning with an open flame. The purpose is to increase flame retardancy.

[0029] A sheath 3 is provided on the outside of the peripheral battery core 12. A wrapping tape 6 is also provided between the outside of the peripheral battery core 12 and the sheath 3. A steel cable 4 is also provided in the wrapping tape 6. A groove 41 is provided between the outsides of the fireproof layers 2 of adjacent peripheral battery cores 12; the steel cable 4 is located in the groove 41. In this solution, four steel cables 4 are provided, and the purpose is to increase the tensile strength of the cable by means of built-in steel cables 4. At the same time, the steel cable 4 is provided on the inside of the wrapping tape, so that the overall cable can be structurally enhanced. The four steel cables form a square space, sandwiching the cable in the middle to improve the structural strength.

[0030] The peripheral cells 12 are arranged in at least one group and are symmetrically arranged outside the central cell 11. Specifically, in this solution, the peripheral cells 12 are arranged in four groups, each group is arranged in a fan-shaped structure, and is arranged around the central cell 11. The purpose of setting the peripheral cells 12 in a symmetrical structure is to offset electromagnetic interference.

[0031] An insulating layer 5 is sleeved between the central battery core 11 and the fireproof layer 2. The insulating layer 5 is made of XLPE. Specifically, the wrapping tape is a halogen-free tape, which is used for various types of smoke-free, low-smoke, clean, highly flame-retardant cables and fire-resistant cables, in order to prevent the generation of harmful substances when the temperature is too high.

[0032] A filling layer is provided in the gap between the wrapping tape 6 and the fireproof layer 2. The filling layer is provided with inorganic fibers. Inorganic fibers, especially inorganic fibers used to make composite materials, have the most important properties of super hardness, strength and low density, and the purpose is to increase the strength between cables and improve the torsional and tensile properties of cables.

It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
