Abstract
Description
Technical Field
[0001] The invention relates to the technical field of pressure-resistant cables, in particular to a pressure-resistant cable with inner and outer armor layers. Background Art
[0002] In the prior art, the requirements for pressure-resistant cables are that they need to be able to withstand external squeezing forces, maintain the integrity of the internal cables, and prevent the internal cables from being damaged when subjected to strong external pressure. There are many types of pressure-resistant cables in the prior art.
[0003] For example, the “Compression-resistant cable inner core and compression-resistant wire and cable” disclosed in Publication (Announcement) No. CN209657828U includes a fixed core structure, an inner core, and a filler. The function of the fixed core structure is to improve the compression resistance of the inner core. The first support body and the second support body serve as a skeleton that can withstand greater pressure. The first support body and the second support body divide the fixed sleeve into independent accommodating cavities, thereby improving the independence of each conductor core and preventing short circuits. In addition, the fixed sleeve can also withstand pressure, further improving the compression resistance.
[0004] For example: the "compression-resistant cable with a pressure-resistant protection structure" disclosed in the publication (announcement) number: CN211929106U, includes a rectangular skeleton, two opposite surfaces of the rectangular skeleton are provided with convex arc grooves, the other two opposite surfaces are provided with concave arc grooves, a wire core one is provided in the center of the rectangular skeleton, and a wire core two is provided inside the two convex arc grooves and the two concave arc grooves, respectively. The outer side of the rectangular skeleton is sequentially coated with a polyurethane sleeve, an aluminum alloy strip interlocking armor layer, a composite insulation shielding layer and a UV-cured silicone rubber outer sheath layer, and the interior of the polyurethane sleeve is honeycomb-shaped. The utility model provides convex arc grooves and concave arc grooves on two pairs of opposite surfaces of the rectangular skeleton, which increases the strength of the rectangular skeleton. During use, the internal structure is more stable and not easily damaged by stretching. The internal structure is compact and has good pressure resistance. The composite insulation shielding layer ensures the softness and high temperature resistance of the cable.
[0005] Most of the above-mentioned technical solutions and existing technical solutions adopt the method of designing an internal skeleton to achieve the compressive resistance of the cable, but the skeleton design alone cannot completely protect the internal cable core structure; because in addition to having good compressive resistance, the cable also needs to have good anti-torsion and anti-deformation capabilities. Because many cables will cause torsion between the layered structures when they are subjected to rotational extrusion, even if a skeleton and other structures are set up inside, since there is no stabilizing mechanism, torsion and separation from the cable core will occur, causing damage to the internal cable core.
[0006] Therefore, in order to solve the above problems, it is necessary to develop a pressure-resistant cable with inner and outer armor layers that has a reasonable structure and can effectively protect the internal cable core from being damaged. Summary of the Invention
[0007] The purpose of the present invention is to provide a pressure-resistant cable with inner and outer armor layers to address the deficiencies in the prior art. The technical solution is as follows:
[0008] An inner and outer armored layer pressure-resistant cable, comprising an inner cable core, the outer portion of the inner cable core being coated with an inner reinforcement layer; the outer portion of the inner reinforcement layer being coated with an inner armor layer; the outer portion of the inner armor layer being coated with an outer armor layer; the outer portion of the outer armor layer being coated with an outer reinforcement layer; the outer portion of the outer reinforcement layer being coated with a wrapping layer; and the outer portion of the wrapping layer being coated with an outer sheath.
[0009] The outer wall of the inner reinforcement layer is provided with a plurality of inwardly recessed slots, and the inner armor layer is provided with a tubular structure. The inner wall of the inner armor layer is provided with a card block corresponding to the position of the card slot. When the inner armor layer is correspondingly covered on the outside of the inner reinforcement layer, the card block is correspondingly embedded in the card slot;
[0010] The outer wall of the inner armor layer is set to a continuous serrated structure, and the inner wall of the outer armor layer is also set to a matching serrated structure. When the outer armor layer is correspondingly covered on the inner armor layer, the serrated structures of the two armor layers are correspondingly fitted together.
[0011] Furthermore, the outer wall of the outer armor layer is a circular outer wall structure, and a plurality of evenly spaced support members are provided between the outer reinforcement layer and the outer armor layer. Through the support of the support members, a support gap is left between the outer reinforcement layer and the outer armor layer.
[0012] Furthermore, a number of support bars are correspondingly installed in the support gap between the outer reinforcement layer and the outer armor layer. The outer diameter of the support bar is adapted to the size of the support gap, and the outer reinforcement layer is correspondingly pressed on the support bar.
[0013] Furthermore, the support members are configured as elastic material structures with elasticity, and there are eight of them in total; correspondingly, there are also eight support gaps in total, and a support bar is correspondingly provided in each support gap.
[0014] Furthermore, the support bars are configured as steel bars made of metal.
[0015] Furthermore, the inner reinforcement layer and the outer reinforcement layer are both made of hard ceramic material; and the inner armor layer and the outer armor layer are both made of hard metal material.
[0016] Furthermore, the inner cable core includes an inner conductor, an inner insulating layer wrapped around the outer side of the inner conductor, an inner shielding layer wrapped around the outer side of the inner insulating layer, and an inner sheath wrapped around the outer side of the inner shielding layer.

The reinforcement layers are all provided as hard ceramic layers, and the armor layers are all provided as tubular metal layers. The four-layer structure effectively increases the external compressive resistance, and the structure is very stable and reliable.
[0019] 2) In the present invention, the outer armor layer and the outer reinforcement layer are not directly set as a layered structure, but are supported by support members, so that a support gap is formed between the two layered structures, and support bars are installed inside the support gap. The outer reinforcement layer is pressed against the support bars, and the stability of the overall structure is increased by the support bars, and the bending resistance of the overall structure is increased by setting the support bars. The overall structural setting is very reasonable and ingenious.
[0020] 3) The present invention also has good anti-deformation and anti-torsion capabilities; first, a card slot and a card block are set between the inner reinforcement layer and the inner armor layer in the present invention.

[0029] The outer wall of the inner reinforcement layer 2 is provided with a plurality of inwardly recessed slots 8, and the inner armor layer 3 is provided with a tubular structure. The inner wall of the inner armor layer 3 is provided with a clamping block 9 corresponding to the position of the clamping slot 8. When the inner armor layer 3 is correspondingly covered on the outside of the inner reinforcement layer 2, the clamping block 9 is correspondingly embedded in the clamping slot 8;
[0030] The outer wall of the inner armor layer 3 is set as a continuous serrated structure 10, and the inner wall of the outer armor layer 4 is also set as a matching serrated structure 10. When the outer armor layer 4 is correspondingly covered on the inner armor layer 3, the serrated structures 10 of the two armor layers are correspondingly fitted together.
[0031] The outer wall of the outer armor layer 4 is a circular outer wall structure, and a number of evenly spaced support members 11 are arranged between the outer reinforcement layer 5 and the outer armor layer 4. Through the support of the support members 11, a support gap 12 is left between the outer reinforcement layer 5 and the outer armor layer 4.
[0032] Several support bars 13 are installed in the support gap 12 between the outer reinforcement layer 5 and the outer armor layer 4 . The outer diameter of the support bar 13 matches the size of the support gap 12 , and the outer reinforcement layer 5 is pressed against the support bar 13 .
[0033] The supporting members 11 are configured as elastic materials with elasticity, and there are eight supporting members 11 in total. There are also eight corresponding supporting gaps 12 in total, and a supporting bar 13 is correspondingly provided in each supporting gap 12 .
[0034] The support bar 13 is configured as a metal reinforcement bar.
[0035] The inner reinforcement layer 2 and the outer reinforcement layer 5 are both made of hard ceramic material; while the inner armor layer 3 and the outer armor layer 4 are both made of hard metal material.
[0036] The inner cable core 1 includes an inner conductor 101 , an inner insulating layer 102 covering the outer side of the inner conductor 101 , an inner shielding layer 103 covering the outer side of the inner insulating layer 102 , and an inner sheath 104 covering the outer side of the inner shielding layer 103 .
