Description

Fiber optic cable

The present invention is a fiber optic cable for transmitting optical signals, and in particular, a fiber optic cable that can prevent fiber breakage caused by pulling, squeezing, and bending when the cable is disposed.

As shown in the first and second figures, a conventional optical fiber cable 10 includes a skin layer 11 which is internally covered with a plurality of beam tubes 12, and at least one or more of the inner tubes 12 are disposed inside. The optical fiber 13 is covered with a tensile wire 14 inside the outer skin layer 11.

In the above-mentioned conventional optical fiber cable 10, when the cable is arranged, the tensile strength of the optical fiber cable 10 can be improved by using the tensile wire 14 coated on the inner surface of the outer skin layer 11 to prevent the cable from being pulled through the bundle tube. 12 The inner fiber 13 is broken, but since the beam tube 12 is a hollow circular tube, the tube wall is made thin, and is made of a flexible plastic material, so when the beam tube 12 is worn inside When the optical fiber 13 is separately drawn from the outer skin layer 11 for the cable arrangement, the fiber 12 is easily broken due to pulling, squeezing, and bending.

The purpose of the present invention is to improve the lack of the above-mentioned conventional optical fiber cable, and to provide a fiber optic cable which can avoid fiber breakage caused by pulling, squeezing and bending when the cable is arranged.

In order to achieve the above object, the optical fiber cable of the present invention comprises an outer skin layer, The inside of the outer skin layer is covered with a plurality of protective sleeves, and the inner center of each protective sleeve is covered with a bundle of tubes, and at least one or more optical fibers are disposed inside each of the inner protective tubes, and the inner sides of each protective sleeve are separately coated There is a tensile line.

With the above configuration, the optical fiber sheathed inside the bundle tube can be further protected by the protective cover covering the outside of the bundle tube, thereby avoiding the breakage of the optical fiber caused by pulling, pressing and bending when the cable is arranged.

The technical means and structure of the present invention for achieving the purpose, together with the embodiment shown in Figures 3 to 6, will be described in detail as follows: as shown in Figures 3 and 4, the optical fiber in the embodiment The cable 20 is illustrated by a fiber optic cable suitable for indoor use. The fiber optic cable 20 includes an outer skin layer 21, and the outer skin layer 21 is internally covered with a plurality of protective sleeves 22, the inner center of each protective sleeve 22. A bundle of tubes 23 is disposed, and at least one or more optical fibers 24 are disposed in the interior of each of the bundles of tubes 23. Each of the two sides of the protective sleeve 22 is respectively coated with a tensile wire 25.

The preferred embodiment of the protective cover 22, as shown in FIG. 5, is made of a plastic material having flexibility, high hardness and low friction coefficient, and is a strip body having a slightly rectangular cross section.

The preferred embodiment of the protective cover 22, as shown in Fig. 5, is provided with a symmetrical V-shaped groove 26 in the center of the upper and lower sides thereof.

The preferred embodiment of the tensile wire 25 is an FRP tensile wire, but is not limited thereto.

As shown in FIG. 6, another embodiment of the present invention, the optical fiber cable 20 further includes a hanging wire 30, the outer surface of the hanging wire 30 is covered with a skin layer 31, and the outer skin layer 31 is provided with a sling 32 and a fiber optic cable. The outer skin layers 21 of the wires 20 are joined together to form a fiber optic cable suitable for outdoor use.

The outer sheath 31 and the sling 32 are coated on the outer surface of the suspension wire 30, and the preferred embodiment is integrally formed with the outer layer 21 of the optical fiber cable 20.

With the above configuration, the present invention can further protect the optical fiber 24 pierced inside the beam tube 23 by the protective cover 22 coated on the outside of the beam tube 23, so as to avoid pulling, when being pulled out of the outer skin layer 21 for the cable arrangement. Extrusion and bending cause breakage of the optical fiber 24.

Therefore, as can be seen from the above, the present invention can avoid the occurrence of the breakage of the bare fiber of the optical fiber due to pulling, squeezing, and bending when the cable is arranged; therefore, the present invention has a prior art compared with the prior art. Significant progress, and its construction is indeed unprecedented, Cheng has already met the requirements of the new patent, 提出 filed a patent application according to law, and prayed for a patent for prayer, to the sense of virtue.

However, the above description is only a feasible embodiment of the present invention, and the embodiment is mainly for exemplifying the technical means and the structure used for the purpose of the present creation, and thus is not It is possible to limit the scope of protection of this creation, and all equivalent changes or modifications in accordance with this creation specification and the scope of patent application shall remain the protection scope covered by this creation.
