Description

Technical Field

[0001] The utility model belongs to the technical field of power cables, and more specifically, it particularly relates to an anti-rolling cable. Background Art

[0002] Wire and cable, abbreviated as cable, is an important infrastructure in urban construction and industrial production. Cables used for transmitting electricity are used in various environments. The quality of the cable determines the basic guarantee of industrial and domestic electricity. Currently, cables have characteristics such as waterproof and wear-resistant. However, since some cables contain multiple stranded cores stacked together, being crushed or stepped on by the outside world easily causes displacement and deformation between the stranded cores, and over time, it is prone to damage or short circuit of the line.

[0003] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and an anti-rolling cable is provided in order to achieve a more practical value purpose. Summary of the Utility Model

[0004] In order to solve the above technical problems, the utility model provides an anti-rolling cable to solve the problem that the stranded cores are prone to displacement and deformation when the cable is crushed or stepped on by the outside world.

[0005] The purpose and effect of an anti-rolling cable of the utility model are achieved by the following specific technical means:

[0006] An anti-rolling cable includes a multi-stranded core formed into a multi-prismatic strip. Each stranded core includes multiple wire cores wrapped by an insulating layer. A multi-prismatic core is arranged between the multi-stranded cores. The multi-stranded cores are wrapped by an outer layer, and a compression bar is clamped between the outer layer and adjacent two stranded cores. The remaining part between the outer layer and the stranded cores is filled with a filling layer.

[0007] Further, the compression bar is in a triangular prism shape, and the inside of the compression bar is hollow to form a multi-prismatic hole.

[0008] Further, the cross-section of the multi-prismatic hole is in an irregular rhombus or triangle shape.

[0009] Further, the outer layer includes a waterproof layer and a wear-resistant layer. The wear-resistant layer is arranged outside the waterproof layer, and the thickness of the wear-resistant layer is greater than that of the waterproof layer.

[0010] Further, a buffer layer is also wrapped on the insulating layer of the stranded core.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] Through the setting of the multi-faceted core, the multi-faceted core is clamped between multiple cable cores to form an anti-extrusion inner core, and the multi-faceted setting prevents dislocation and offset between the multiple cable cores. In addition, the compression-resistant strips increase the structural strength between the cable cores, making the outer layer surrounding the cable cores not easily deformed due to rolling and extrusion.

[0021] Example:

[0022] As shown in the attachedFigure 1 to the attached Figure 3 as shown in:

[0023] The utility model provides an anti-rolling cable, which includes a multi-strand core 1 formed into a multi-prismatic strip. Each strand core 1 includes multiple wire cores wrapped by an insulating layer 2, which plays an insulating role for the wire cores and at the same time prevents interference between other strand cores 1. A buffer layer 3 is further wrapped on the insulating layer 2 of the strand core 1. The thickness of the buffer layer 3 is much larger than that of the insulating layer 2. The buffer layer 3 can be made of solid styrene-butadiene rubber material or hollow styrene-butadiene rubber, and elastic foam plastic is used as the internal filling, which plays an elastic buffering role and has a fast shape recovery, preventing the cable from being rolled and causing the internal strand core 1 to be displaced.

[0024] A multi-prismatic core 4 is arranged between the multi-strand cores 1. The edges of the multi-prismatic core 4 also make the strand cores 1 in contact with it not easy to be displaced. And the multi-prismatic core 4 is made of rubber material, which has compressive resistance and anti-aging properties. The multi-strand cores 1 are wrapped by an outer layer, and a compressive strip 5 is clamped between the outer layer and two adjacent strand cores 1. As Figure 2 and Figure 3 shown, the compressive strip is in a triangular prism shape, and a multi-prismatic hole 501 is formed inside the compressive strip 5. The multi-prismatic hole 501 can be an irregular rhombus or a triangle, which has a strengthening structure and is not easy to collapse, protecting the problem that the vulnerable part of the gap between adjacent strand cores 1 is easy to sink and collapse.

[0025] The rest of the part between the outer layer and the strand core 1 is filled with a filling layer 6 to increase the tightness of the overall structure and the compressive capacity of the cable.

[0026] Among them, the outer layer includes a waterproof layer 7 and a wear-resistant layer 8. The wear-resistant layer 8 is arranged outside the waterproof layer 7, and the thickness of the wear-resistant layer 8 is greater than that of the waterproof layer 7. The waterproofness and wear-resistant surface layer increase the service life of the cable.

[0027] The embodiments of the present utility model are given for the purpose of illustration and description, and are not exhaustive or limit the present utility model to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present utility model, and enable those of ordinary skill in the art to understand the present utility model and thus design various embodiments with various modifications suitable for specific purposes.
