the inner wall of the sheath layer 100 is uniformly provided with a plurality of arc-shaped arches 101 around the axial center of the cable, and the number of the arc-shaped arches 101 is even, so that the inner wall of the sheath layer 100 has a wave-shaped structure which is regular on the radial section of the cable and orderly connected end to end;
the sheet type explosion-proof layer 200 is coated on the outer layer of the gel layer 400, and the gel layer 400 coats the central composite conductive wire 300;
the sheet type explosion-proof layer 200 comprises an outer lamination 201 and an inner lamination 202, wherein the outer lamination 201 and the inner lamination 202 are of arc structures on the radial section of the cable, and are actually strip-shaped and arranged along the axial direction of the cable;
the outer laminations 201 are outwards arched along the radial direction and are embedded in the concave of the inner part of the sheath layer 100 with the wavy structure, the inner laminations 202 are correspondingly arranged on the radial inner side of the arc-shaped arch 101 and are separated from the arc-shaped arch 101, and the arc-shaped two ends of the inner laminations 202 are buckled on the inner sides of two adjacent outer laminations 201, namely, a second wave-like structure is formed;
the radial inner sides of the outer laminates 201 are provided with elliptical beam tubes 203 at intervals, the long axes of the elliptical beam tubes 203 are arranged along the radial direction of the optical cable, the elliptical beam tubes 203 are outwards abutted against the inner sides of the outer laminates 201 and inwards abutted against the outer surfaces of the gel layers 400, and the two ends of the elliptical beam tubes 203 in the short axis direction are abutted against the two circumferential sides of the adjacent inner laminates 202;
the elliptical beam tube 203 is provided with a constraint structure, so that the sheet type explosion-proof layer 200 can be prevented from scattering, the stability of the structure can be maintained to a certain extent, and a certain force guiding effect can be achieved.
Under the cooperation of the above structure, the sheet type explosion-proof layer 200 is a relatively loose structure, when the cable is subjected to strong impact force, the force dispersion can be realized through the structure vibration, the phenomenon that even the cable single point is subjected to the action of the excessively strong impact force is reduced, namely, as shown in fig. 2, when the outer lamination 201 is subjected to the action of the external force impact, the vibration can be generated, the inner lamination 202 which is buckled on the sheet type explosion-proof layer 200 conducts along the circumferential direction, the force dispersion is realized, meanwhile, the outer lamination 201 at the directly stressed part can deform and shrink inwards in the radial direction, a certain buffer effect is generated in a deformation and shrink mode, the cooperation setting mode of the outer lamination 201 and the inner lamination 202 and the cooperation setting mode of the outer lamination 201 and the oval beam tube 203 can drive the inner lamination 202 and the oval beam tube 203 to generate deformation motion as shown in fig. 3, the deformation of the inner lamination 202 and the oval beam tube 203 generates secondary buffer, the abutting part of the oval beam tube 203 generates the circumferential opposite acting force in the secondary buffer process, the similar structure stress is generated, the overall impact resistance performance of the explosion-proof cable is improved, and the overall impact resistance performance is concentrated, and the whole impact resistance performance of the cable is improved.
Further, the method comprises the steps of,
a buffer layer 500 is coated on the outer side of the gel layer 400;

by arranging the buffer layer 500 and the arch structure 501, an impact-resistant buffer effect can be further realized, after the sheet-type explosion-proof layer 200 of the cable is subjected to the action of external strong impact force, the sheet-type explosion-proof layer 200 can realize the buffer effect of multiple dispersion forces through the vibration effect and circumferential conduction of the sheet-type explosion-proof layer 200, but the oval beam tube 203 still generates a certain inward guide force, so that the central composite conductive wire 300 inside the cable is subjected to impact action to cause breakage, after the structure is arranged, a second structural stress concentration point is formed, namely, the abutting part of the oval beam tube 203 and the arch structure 501, because the inner lamination 202 is stressed, a certain radial inward extrusion action is generated on the arch structure 501, the extrusion action leads the arch structure 501 to form a certain circumferential expansion, and the oval beam tube 203 is expanded in the circumferential direction along the minor axis direction after being stressed, so that the expansion trends of the arch structure 501 and the oval beam tube 203 are opposite, the opposite movement expansion trends lead the two opposite acting points to generate opposite acting forces, and further lead the extrusion and the second stress concentration points of the two acting forces to counteract each other;
based on the above process, the cable of the present invention can effectively prevent the central composite conductive wire 300 from being directly stressed by the impact force of explosion, form multi-stage and multi-time buffering and dispersing, and can actually produce better use effect compared with the conventional hard explosion-proof and/or compression-resistant structure due to the characteristics of large impact force of explosion and short duration.
Still further, the method comprises the steps of,
the cavity 502 is arranged in the arch structure 501, the arrangement of the cavity 502 can further prevent the inner lamination 202 from conducting the acting force inwards by extruding the arch structure 501, and the arch structure 501 is more easily subjected to circumferential unfolding deformation generated after the acting force of the inner lamination 202, and better acts on the elliptical beam tube 203 to generate an oblique outward acting force on the elliptical beam tube 203, and meanwhile, the elliptical beam tube 203 is effectively prevented from conducting the acting force inwards in the radial direction.
