Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of optical fiber cables, in particular to a flat central tube communication optical cable. Background Technique
[0002] A communication optical cable is composed of a cable core formed by several (cores) of optical fibers (generally from several cores to thousands of cores) and an outer protective layer. Compared with traditional symmetrical copper loops and coaxial copper loops, optical fibers have much larger transmission capacity, less attenuation, longer transmission distance, smaller volume, lighter weight, no electromagnetic interference, and lower cost. They are the most promising current communication transmission media. Currently, communication optical cables include central tube communication optical cables.
[0003] The existing central tube communication optical cable still has the following problems in use: Since there is a central tube in the communication optical cable and the outer polyethylene sheath is usually also arranged in a cylindrical shape, when the actual communication optical cable is arranged, it often needs to be arranged close to the wall, and its cylindrical outer side is not easy to fit tightly with the installation surface. In addition, to increase the mechanical strength of the overall communication optical cable, two steel wires are usually penetrated through the outside of the wire core of the communication optical cable. However, due to its actual small stress area, when the communication optical cable is stressed at the end face and the side, the auxiliary bearing capacity of the two steel wires on both sides is limited and cannot play a good role in preventing pressure on the internal wire core mechanism. Content of the Utility Model

[0005] In view of the deficiencies of the prior art, the utility model provides a flat central tube communication optical cable, which solves the problems put forward in the background technique.
[0006] (II) Technical Solutions

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.
[0022] Please refer to Figures 1 to 4 , in the embodiment of the present utility model, a flat central tube communication optical cable includes an outer protection mechanism 1; a core mechanism 2, which is arranged inside the outer protection mechanism 1. The outer protection mechanism 1 includes a polyethylene sheath 11. The upper, lower, and both side end faces of the polyethylene sheath 11 are provided with fitting planes. A group of air guide grooves 12 are opened at both the upper and lower ends of the polyethylene sheath 11. A group of air guide grooves 12 are two and are symmetrically arranged. The outer polyethylene sheath 11 of the overall communication optical cable is arranged in a flat shape. Its core mechanism 2 is arranged in the middle of its polyethylene sheath 11, and the upper, lower, and both side end faces of its polyethylene sheath 11 are provided with fitting planes, which is conducive to arranging it by fitting against the wall. At the same time, since a group of air guide grooves 12 are opened at both the upper and lower ends of its polyethylene sheath 11, it is conducive to the air circulation at the polyethylene sheath 11, and further conducive to the heat dissipation of the core mechanism 2 inside its polyethylene sheath 11 through the polyethylene sheath 11.
[0023] The core mechanism 2 includes an inner polyethylene sleeve 21 fixedly sleeved on the inner wall of the polyethylene sheath 11. A core body is arranged at the middle position inside the inner polyethylene sleeve 21. Two groups of steel wire strips 24 are arranged through the inner polyethylene sleeve 21. The two groups of steel wire strips 24 are located outside the core body and are symmetrically arranged. One group of steel wire strips 24 has two and is symmetrically arranged up and down. An arc-shaped steel wire sheet 25 is fixedly connected between the end faces of one group of two steel wire strips 24 close to the core body. Steel wire bearing mechanisms are arranged at both ends of the inner polyethylene sleeve 21, that is, two groups of steel wire strips 24 are symmetrically arranged at both ends inside the inner polyethylene sleeve 21. Each group of steel wire strips 24 has two and is symmetrically arranged up and down. At the same time, an arc-shaped steel wire sheet 25 is used to connect between each group of two steel wire strips 24. When the overall communication optical cable end face and side are stressed, the steel wire structures on both sides can effectively assist in bearing, thereby playing a good role in preventing pressure on the internal core body.
[0024] A through groove 26 for fixing the core body is opened at the middle position inside the inner polyethylene sleeve 21. The core body includes a corrugated steel strip 27 fixedly connected to the inner wall of the through groove 26. A water-blocking tape 28 is fixedly connected to the inner side wall of the corrugated steel strip 27. A loose tube 29 is fixedly connected to the inner side wall of the water-blocking tape 28. A fiber core 211 is arranged at the center position inside the loose tube 29. Five fiber cores 211 are arranged at equal angles outside the central fiber core 211. An insulating filler 210 is filled outside the six fiber cores 211 and inside the loose tube 29. The overall flat type central tube communication optical cable can transmit optical fiber signals through the multiple fiber cores 211 of its core body.
[0025] First fitting grooves 22 for fixedly installing the steel wire strips 24 are opened at both ends inside the inner polyethylene sleeve 21. Second fitting grooves 23 for fixedly installing the arc-shaped steel wire sheets 25 are opened at both ends inside the inner polyethylene sleeve 21, playing a role in firmly installing the steel wire bearing mechanism inside the inner polyethylene sleeve 21.
[0026] The working principle of the present utility model is as follows: The overall flat center tube type communication optical cable can transmit optical fiber signals through multiple optical fiber cores 211 of its core body. Since the outer polyethylene sheath 11 of the overall communication optical cable is arranged in a flat shape, its core mechanism 2 is arranged in the middle of its polyethylene sheath 11, and the upper, lower, and both side end faces of its polyethylene sheath 11 are provided with fitting planes, which is conducive to arranging it by fitting against the wall. At the same time, since air guiding grooves 12 are provided at both the upper and lower ends of its polyethylene sheath 11, it is conducive to the air circulation at the polyethylene sheath 11, and further conducive to the heat dissipation of the core mechanism 2 inside its polyethylene sheath 11 through the polyethylene sheath 11. In addition, steel wire bearing mechanisms are arranged at both ends of its inner polyethylene sleeve 21, that is, two groups of steel wire strips 24 are symmetrically arranged at both ends inside the inner polyethylene sleeve 21, each group of steel wire strips 24 has two and is symmetrically arranged up and down, and at the same time, the two steel wire strips 24 in each group are connected by an arc-shaped steel wire sheet 25. When the end face and side of the overall communication optical cable are stressed, the steel wire structures on both sides can effectively assist in bearing, thereby playing a good role in preventing pressure on the internal core body.
[0027] The above is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, making equivalent substitutions or changes, should be covered by the protection scope of the present utility model.
