In the application, the existence of the elevated component makes the elevated component overcome the defects in the prior art, the high extension of the elevated extension body increases the space and can form a plurality of accommodating cavities, but the reinforcement body does not need to be thick, so that the cost is saved, the weight is lightened, and the flexibility is better; the filling body realizes enough strength and firmer combination of the elevated body; the embodiments in fig. 10 to 14 of the present application not only achieve the quick replacement and assembly of the light-transmitting and electricity-transmitting components, but also achieve the quick replacement and assembly of the elevated body, so as to be more flexible and reliable, the compression and the stretching of the opening component enable the structure and the diameter of the product to be flexibly changed, the framework-type optical cable in the prior art must increase the integral diameter in order to achieve a large core number, the material cannot be reduced, the cost is high, the volume is large, and once the structure is formed, the structure cannot be changed, and once the local part is damaged, the whole structure needs to be changed; in the layer stranded optical cable in the prior art, the structure cannot be changed after the optical cable is formed, and the larger the core number is, the more the sleeves are required, the larger the diameter of the central reinforcing part is, so that the product has the defects of large diameter, high cost, heavy weight, poor flexibility, two-time cabling and the need of using a large amount of manpower, material resources, electric power, machine equipment and fields when the number is larger than twelve loose sleeves; in the application, the elevated components can be integrally formed or produced for standby and are relatively universal, and can be finished on one extrusion molding device, so that the investment of the device, the occupation of a field, the large use of personnel and the like are saved; when the device is used, the loose sleeve does not need to be withdrawn, the binding material is cut, and when the device is recovered, manual twisting and binding are not needed, only the required yarn is needed to be taken and put, so that the labor cost is saved, the efficiency is higher, and the speed is higher; the supporting cavity is formed, materials are obviously saved, and in addition, the reinforcing part does not need to be large and only needs to meet the strength requirement; through accurate accounting, compared with a layer stranded optical cable, the non-fiber comprehensive cost of the optical cable with more than 96 cores is saved by 30 percent.

The utility model discloses following main beneficial effect has: the cost is lower, the outer diameter is smaller, the soft bending performance is better, the universality is stronger, the manufacturing speed is faster, the required equipment and the required field are fewer, the technical requirement of production personnel is lower, and the inspection and construction efficiency is higher.

The above-mentioned embodiments are merely preferred technical solutions of the present invention, and should not be construed as limitations of the present invention. The protection scope of the present invention shall be defined by the claims and the technical solutions described in the claims, including the technical features of the equivalent alternatives as the protection scope. Namely, equivalent alterations and modifications within the scope of the invention are also within the scope of the invention.
