A triangular optical cable as shown in figure 1 specifically comprises:
the sheath 100, the reinforcing member cladding 200 and the core wire are arranged in sequence from outside to inside;
the sheath 100 is a triangular special-shaped sheath, a water drop-shaped cavity 101 is arranged in the sheath 100, the tip of the water drop-shaped cavity 101 faces the tip of the top of the sheath 100, and the round head 1012 faces the side opposite to the tip;
the reinforcing part cladding 200 consists of a supporting rib 202 and an annular cladding 201, the annular cladding 201 is arranged at the round head 1012 part of the water drop-shaped cavity 101 and is abutted against the inner wall of the round head 1012 part of the water drop-shaped cavity 101, an opening is arranged in the direction facing the tip 1011 of the water drop-shaped cavity 101, two ends of the opening extend towards the tip 1011 part of the water drop-shaped cavity 101 to form the supporting rib 202, and the two formed supporting ribs 202 are abutted against each other, are in sealing contact with each other and extend to the tip 1011 end of the water drop-shaped cavity 101 and are abutted against the inner wall of the tip 1011 end of the water drop-shaped cavity 101;
the inner ends of the support ribs 202 are shown as being in rounded connection with the annular envelope 201, and the inner ends of the two support ribs 202 are shown as being separated from each other in fig. 3;
the core wire comprises a plurality of optical fibers 300 fixed by a tape layer 400, and the optical fibers 300 are optical fiber bundles formed by single optical fibers or a plurality of optical fibers;
the wrapping layer 400 is made of common materials such as a non-woven fabric wrapping tape and is used for accommodating and fixing the optical fibers 300;
the wrapping layer 400 is externally provided with a tooth-shaped structure 500, the tooth-shaped structure 500 is a circular rubber tube, the outer diameter of the tooth-shaped structure is slightly smaller than the inner diameter of the annular wrapping layer 201, the inner surface of the tooth-shaped structure is provided with a tooth-shaped structure 501 pointing to the axis, and the tooth-shaped structure 501 is uniformly arranged along the circumference of the axis and is abutted against the outer surface of the wrapping layer 400.
The optical cable with the structure has the characteristics of easy arrangement, high stability and the like, is not easy to translocate when being laid in places with complex environments such as disaster relief sites, mining areas and the like, and enables the optical fiber 300 in the core wire not to be directly influenced by impact force under the action of the supporting ribs 202 and the annular cladding 201;
in particular, the method comprises the following steps of,
after the optical cable with the above structure is normally laid and used, the supporting ribs 202 are necessarily arranged upwards, therefore, when the strong impact force acts on the base, the strong impact force acts on the base from top to bottom, under the action of the strong impact force, the support rib 202, as the main stress portion, is inevitably pressed down to form a certain displacement, the displacement is first of all damped by the tooth structure 500, and in the process, as shown in FIG. 2, the opening of the ring-shaped covering 201 opens towards both sides, which drives the deformation of the supporting rib 202 to make the vertical downward guiding force change rapidly, gradually forming the guiding force of the tangential core wire, driving the deformation of the water-drop-shaped cavity 101 of the integral sheath 100, the impact force is dispersed through the instant response deformation and the force guiding after the initial stress, and the force is actually guided downwards along the tangential direction of the core wire in an inclined way, so that the direct stress of the core wire after the initial stress is avoided;
meanwhile, as shown in fig. 2, the tooth-shaped structure 500 with the tooth-shaped structure 501 inside is selected, which is more favorable for promoting the deformation of the annular cladding 201 and changing the force guiding direction of the supporting rib 202, because the tooth-shaped structure 500 is changed from a circle to an ellipse after being stressed compared with a conventional round rubber tube, and only changes the shape, the tooth-shaped structure 501 at the upper end and the lower end in the radial cross section of the optical cable is extruded towards the left side and the right side after being stressed, actually, the thickness of the tooth-shaped structure is reduced, or the filling density is reduced, while the tooth-shaped structures 501 at the left side and the right side are folded, although the absolute thickness is not directly increased, a part with larger relative thickness is obviously formed, the filling density is increased, which is favorable for driving the annular cladding 201 to open towards the left side and the right side, and then driving the inner end of the supporting rib 202 to move towards the left side and the right side, changing the supporting angle of the supporting rib 202, and then changing the inward conducting direction of the impact force, so that it gradually becomes a guiding force.
In addition, compared to the tooth structure 501a shown in fig. 4, the tooth structure 501a at the top end is just separated from the opening of the annular cladding 201, and cannot be effectively deformed in time to form the thickness difference and the packing density difference of the tooth structure 500a, so the effect is poor, and therefore, the tooth structure 500 with the tooth structure 501 on the inner wall has a better use effect.
Further, in the above-mentioned case,
the two corners of the bottom edge of the sheath 100 are correspondingly provided with the bevel-shaped cavities 102, the bevel angles of the bevel-shaped cavities 102 are equal to those of the two corners of the bottom edge of the sheath 100, the whole body is arranged in an equiangular mode, the bevel walls are parallel to the edges of the sheath 100, bevel reinforcing pieces 600 are arranged in the bevel-shaped cavities 102, the bevel reinforcing pieces 600 are in bevel shapes on the radial cross sections of the optical cables and are tightly attached to the inner walls of the bevel-shaped cavities 102, but the inner side walls of the corner parts of the bevel-shaped cavities 102 are separated from the bevel reinforcing pieces 600, and deformation buffer areas are formed;
after setting up foretell dog-ear cavity 102 and dog-ear reinforcement 600, can make the optical cable receive strong impact force, whole sheath 100 is compressed from top to bottom after, reduce the compression degree of water droplet shape cavity 101, when making sheath 100 bottom compression deformation increase form better cushioning effect, promote the broadening deformation of water droplet shape cavity 101 button head 1012 part, make support rib 202 can change external force more fast more effectively, avoid sheath 100 extrusion heart yearn to lead to signal transmission to be obstructed scheduling problem to take place simultaneously.
