Description

Technical Field

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

[0002] Wires and cables are wire products used to transmit electrical (magnetic) energy, information and realize electromagnetic energy conversion. Soft cables refer to cables made of multiple strands of fine copper wires. The cables usually have dozens of cores and a small bending radius.

When bent and stretched during installation, the cables may break or the surface may crack, thereby exposing the battery cells. This will not only affect the normal use of the flexible cables, but also reduce safety and shorten the service life of the cables. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4As shown, a tensile-resistant low-voltage soft cable comprises a filling shell 1, which is made of a flexible material. A cavity 2 is opened on one side of the filling shell 1. The number of cavities 2 is several and they are all distributed in a ring array at the center of the filling shell 1. The inner cavity of the cavity 2 is provided with a protective layer 3, and the inner cavity of the protective layer 3 is fixedly connected with a battery core 4. The protective layer 3 can protect the battery core 4, thereby improving the tensile strength of the battery core 4. The surface of the protective layer 3 is fixedly connected to the inner wall of the cavity 2. The protective layer 3 is designed with a polypropylene material. Under the action of the material of the protective layer 3, the tensile strength is extremely high, and it has excellent tensile resistance, rigidity, high temperature resistance and other characteristics. It can effectively protect the battery core 4, thereby reducing the possibility of the cable breaking during use, and effectively improving the cable. The service life of the cable can be improved, and the material can also isolate the battery core 4, so that the battery core 4 will not easily contact with other battery cores 4 when in use. At the same time, the material of the protective layer 3 has good insulation, which effectively improves the safety of the cable when in use. The inner cavity of the filling shell 1 is provided with a mounting strip 5, and the surface of the mounting strip 5 is fixedly connected to the inner wall of the filling shell 1. The mounting strip 5 is designed as a flexible steel wire. Under this effect, the tensile strength of the cable can be further improved, so that the filling shell 1 will not easily be over-stretched when the cable is over-stretched. The surface of the filling shell 1 is embedded with a stretching strip 6, and the number of the stretching strips 6 is several. The stretching strips 6 are designed with nylon material. Under the effect of the material, the filling shell 1 can be stretched and bent. The filling shell 1 will not break easily, so that the battery cells 4 will not contact each other and conduct electricity to each other, further improving the tensile strength of the filling shell 1. A braided layer 7 is arranged on the surface of the filling shell 1, and the inner wall of the braided layer 7 is fixedly connected to the surface of the filling shell 1. The braided layer 7 is made of glass fiber. Under the action of the material, the strength of the entire cable can be improved, and the bending of the cable is not affected under the action of the material. The tensile strength of the cable can also be improved. A protective layer 9 is arranged on the surface of the braided layer 7, and the inner wall of the protective layer 9 is fixedly connected to the surface of the braided layer 7. The protective layer 9 is made of rubber. Under this action, the parts inside the protective layer 9 can be protected to prevent water and foreign matter from entering the protective layer 9 and affecting the battery cells 4. In normal use, a positioning block 8 is fixedly connected to the surface of the braided layer 7, and a positioning groove 10 is provided on the inner wall of the protective layer 9. The cross-sectional shapes of the positioning block 8 and the positioning groove 10 are both T-shaped structural designs. The positioning block 8 is made of the same material as the braided layer 7. The positioning block 8 is used in conjunction with the positioning groove 10. Under the effect of the shape, the connection strength between the braided layer 7 and the protective layer 9 can be increased to prevent the protective layer 9 from easily separating from the surface of the braided layer 7, thereby improving the use strength of the cable. A wear-resistant layer 11 is provided on the surface of the protective layer 9. The inner wall of the wear-resistant layer 11 is fixedly connected to the surface of the protective layer 9. The wear-resistant layer 11 is designed with a polyurethane material. Under this effect, the cable can have high mechanical strength, wear resistance and impact resistance, so that it can withstand heavy pressure and frequent friction.In addition, polyurethane material has excellent chemical corrosion resistance and can resist corrosion from a variety of chemical substances such as acid, alkali, and salt, further improving the service life of the cable and increasing the applicability of the cable.

[0022] It is worth noting that the technical features such as the battery cell 4 proposed in this technical solution should be regarded as prior art. The specific structure, working principle, and possible control method and spatial layout method of these technical features can be selected according to conventional methods in the field, and this technical solution will not be further elaborated.

[0023] Working principle: First, when using the cable, the protective layer 3 can protect the battery core 4, so that the battery core 4 will not break easily when the cable is over-stretched, and with the cooperation of the mounting strip 5 and the stretching strip 6, the strength of the filling shell 1 can be increased, so that the cable will not undergo a large shape change when stretched, reducing the possibility of cable breakage, effectively improving the service life of the cable, and with the cooperation of the braided layer 7, the filling shell 1 can also be protected to avoid large-scale tensile deformation, thereby improving the protection effect on the battery core 4, and when using the cable, the normal bending of the cable will not be affected by the material of the mounting strip 5, the stretching strip 6, and the braided layer 7 itself, thereby increasing the applicability of the cable.
