Description

Technical Field

[0001] This utility model relates to the field of optical fiber communication technology, and in particular to a high-strength, pressure-resistant optical fiber cable. Background Technology

[0002] Plastic optical fiber has the following structure: a core fiber containing transparent resin is surrounded by a sheath layer containing resin with a refractive index lower than that of the transparent resin. This sheath layer serves as a medium for transmitting optical signals within the core by reflecting light at the boundary between the core and the sheath layer. Compared to silica glass optical fiber, plastic optical fiber offers advantages such as superior flexibility and the ability to utilize the advantages of larger diameter fibers that facilitate core overlap during connection.

[0003] The prior art (announcement number: CN108008482B, announcement date: 2020.06.30) discloses a plastic optical fiber cable, which has excellent durability in harsh environments and effectively suppresses transmission loss.

[0004] However, neither the above solutions nor existing technologies improve the structure of the cable itself. Ordinary cables have poor compressive strength, while the above solutions use material improvements to make the cables wear-resistant. However, the cables are still prone to breakage, deformation, and damage when subjected to pressure. Therefore, it is necessary to design a high-strength compressive strength structure for optical fiber cables to suit different application scenarios. Utility Model Content

[0005] To overcome the shortcomings mentioned above, this utility model provides a technical solution that can solve the above problems.

[0006] A high-strength, pressure-resistant optical fiber cable includes an outer sheath, inside which is provided an elastic support and a plurality of hexagonal conduits, the elastic support and the plurality of hexagonal conduits forming a honeycomb structure; adjacent hexagonal conduits are separated by an elastic support, and the plurality of hexagonal conduits form a staggered avoidance structure.

[0007] When the outer sheath is compressed, the elastic support undergoes elastic deformation, causing several hexagonal conduits to squeeze against each other.

[0008] Furthermore: the elastic support is integrally formed with a pressure-resistant tube, and several hexagonal conduits are arranged inside the pressure-resistant tube, with an outer sheath fitted and installed on the outside of the pressure-resistant tube.

[0009] Furthermore: the outer sheath has a circular cross-section, and the pressure-resistant tube has a hexagonal cross-section; when the outer sheath is under pressure, the upper arm of the pressure-resistant tube is under pressure inside the outer sheath and rotates to a state parallel to the pressure surface.

[0010] Furthermore, the wall thickness of the hexagonal conduit is greater than the wall thickness of the elastic support, so that the elastic support between three adjacent hexagonal conduits forms a triangular structure.

[0011] Furthermore: the six corners of the outer edge of the hexagonal conduit are all fixedly connected to the elastic bracket;

[0012] Under normal conditions, the elastic support between three adjacent hexagonal conduits forms a triangular structure. Under pressure, the elastic support between the three adjacent hexagonal conduits changes from a triangular structure to a trapezoidal structure.

[0013] Furthermore: a cable core is installed inside the hexagonal conduit, and bonding adhesive is installed in the gap between the hexagonal conduit and the cable core.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The outer sheath, elastic support, and hexagonal conduit are used to provide compression resistance to the cable core. When the outer sheath is compressed, the adjacent hexagonal conduits are separated by the elastic support, so the hexagonal conduits will not make rigid contact with each other. The elastic support has a certain elastic force and can elastically return to the honeycomb structure after being compressed, thus having a better compression resistance.

[0016] 2. Because the internal hexagonal conduit is much stiffer than the elastic support, it can provide effective support for the cable core. At the same time, it can use the elastic support for compression resistance and recovery, which is convenient for practical use and has a high-strength compression resistance effect.

[0024] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.

[0026] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] like Figure 1-4As shown, this utility model discloses a high-strength pressure-resistant optical fiber cable, including an outer sheath, an elastic support and a plurality of hexagonal conduits are provided inside the outer sheath, and the elastic support and the plurality of hexagonal conduits form a honeycomb structure; two adjacent hexagonal conduits are separated by an elastic support, and the plurality of hexagonal conduits form a staggered avoidance structure.

[0030] When the outer sheath is compressed, the elastic support undergoes elastic deformation, causing several hexagonal conduits to squeeze against each other.

[0031] The principle is as follows: the outer sheath, elastic support, and hexagonal conduit are used to provide compression resistance to the cable core. When the outer sheath is compressed, the adjacent hexagonal conduits are separated by the elastic support, so they do not come into rigid contact with each other. The elastic support has a certain elastic force and can elastically return to the honeycomb structure after being compressed, which has a better compression resistance. Since the internal hexagonal conduit is much harder than the elastic support, it can provide effective support to the cable core. At the same time, the elastic support can be used for compression resistance and recovery, which is convenient for practical use and has a high-strength compression resistance.

[0032] Furthermore: the elastic support is integrally formed with a pressure-resistant tube, and several hexagonal conduits are set inside the pressure-resistant tube. The outer sheath is sleeved and installed on the outside of the pressure-resistant tube; it can play a sufficient role in resisting pressure and ensure the stable sleeve assembly of the outer sheath on the elastic support.

[0033] Furthermore: the outer sheath has a circular cross-section, and the pressure-resistant tube has a hexagonal cross-section; when the outer sheath is compressed, the upper arm of the pressure-resistant tube is compressed inside the outer sheath and rotates to a state parallel to the pressure surface. If the compression speed is fast, the upper arm of the pressure-resistant tube cannot quickly rotate to a state parallel to the pressure surface, but the elastic support can still provide pressure-resistant buffer for the hexagonal conduit, and the elastic support can quickly reset after compression, thereby realizing the restoration of the optical fiber cable.

[0034] Furthermore, the wall thickness of the hexagonal conduit is greater than the wall thickness of the elastic support, so that the elastic support between three adjacent hexagonal conduits forms a triangular structure; this can form a stable triangular structure for support, resulting in better compressive strength.

[0035] Furthermore: the six corners of the outer edge of the hexagonal conduit are all fixedly connected to the elastic bracket;

[0036] Under normal conditions, the elastic support between three adjacent hexagonal conduits forms a triangular structure. Under pressure, the elastic support between the three adjacent hexagonal conduits changes from a triangular structure to a trapezoidal structure.

[0037] When under pressure, the cross-section of the outer sheath changes from a circle to an ellipse. At this time, the ellipse of the outer sheath stretches the pressure-resistant tube of the elastic support into the corresponding shape, thereby pulling the side of the elastic support that is parallel to the pressure surface, making it parallel to the pressure surface. At this time, the elastic support of the three adjacent hexagonal conduits changes from a triangular structure to a trapezoidal structure. After changing to a trapezoidal structure, several hexagonal conduits can still be supported by the elastic support, thereby achieving the technical effect of high strength pressure resistance.

[0038] Furthermore: a cable core is installed inside the hexagonal conduit, and bonding adhesive is installed in the gap between the hexagonal conduit and the cable core; this ensures the stable installation of the cable core inside the hexagonal conduit.

[0039] This embodiment does not impose any limitation on the shape, material, structure, etc. of this utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model shall fall within the protection scope of this utility model.
