Description

Technical Field

[0001] The utility model relates to the technical field of data transmission lines, in particular to an optical fiber high-definition line. Background Art

[0002] Optical fiber is the abbreviation of optical fiber. It is a fiber made of glass or plastic that can be used as a light transmission tool. The fine optical fiber is encapsulated in a plastic sheath so that it can bend without breaking. The existing Chinese utility model patent with application number 202020415620.2 discloses a high-definition data cable that improves the mechanical strength of optical fiber. It achieves the effect of facilitating the disassembly of the connector by setting threads, support blocks and fixing blocks, improves the efficiency of connector disassembly, ensures that the optical fiber body is easy to maintain, and improves the practicality of the equipment; however, in its structure, the rubber pad covers the protective pad. When in contact with the connector, the rubber pad needs to expand outward. Since the rubber pad is entirely covered on the outside of the protective pad, its end needs to be partially cut when expanding outward to ensure the expansion. The rubber pad is a whole, and it needs to be cut with the help of tools when cutting, which is inconvenient to install. Utility Model Content

[0003] The purpose of the utility model is to provide an optical fiber high-definition cable that is easy to install with a connector and ensures stability in view of the deficiencies in the above-mentioned background technology.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions for an optical fiber high-definition cable:

[0005] An optical fiber high-definition cable comprises a plurality of optical fiber bodies, an inner sheath layer is arranged on the outer side of the plurality of optical fiber bodies, a filler is arranged between the inner sheath layer and the optical fiber body, a buffer layer is arranged on the outer side of the inner sheath layer, an outer sheath layer is arranged on the outer side of the buffer layer, and a long strip-shaped groove is arranged on the outer side surface of the inner sheath layer, and a plurality of groups of grooves are arranged, and the buffer layer is divided into a plurality of sections, and positioning parts which are respectively inserted into adjacent grooves are arranged at both ends of each section of the buffer layer, and the adjacent positioning parts of two adjacent sections of the buffer layer are fitted together and inserted into a groove.

[0006] A further improvement of the optical fiber high-definition line of the utility model is that four groups of grooves are arranged evenly, and the buffer cushion layer is divided into four groups of arc cushion layers.

[0007] A further improvement of the optical fiber high-definition cable of the utility model is that a pressure-resistant layer is provided between the inner sheath layer and the filler.

[0008] A further improvement of the optical fiber high-definition line of the utility model is that a plurality of evenly distributed second grooves are arranged on the inner circumference of the inner sheath layer, a reinforcing member is arranged in the second groove, and the reinforcing member protrudes from the second groove to abut against the pressure-resistant layer.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] The buffer layer designed in the utility model is a split design. When the optical fiber is connected to the connector, the buffer layer can be easily separated, which is conducive to the outward expansion of the end when matching with the connector, thereby more conveniently ensuring the stability of the connection with the connector.

[0013] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0014] like Figure 1 As shown, an optical fiber high-definition cable includes a plurality of optical fiber bodies 1, an inner sheath layer 4 is arranged outside the plurality of optical fiber bodies, a filler 2 is arranged between the inner sheath layer and the optical fiber body, and the filler can be an existing waterproof compound material. A buffer layer 6 is arranged outside the inner sheath layer, an outer sheath layer 8 is arranged outside the buffer layer, and a long strip groove 5 is arranged on the outer surface of the inner sheath layer, and the grooves are arranged in multiple groups. The buffer layer is divided into a plurality of sections, and both ends of each section of the buffer layer are provided with positioning parts 7 respectively inserted into adjacent grooves, and the adjacent positioning parts of two adjacent sections of the buffer layer are fitted together and inserted into a groove.

[0015] Preferably, four groups of grooves are provided and evenly arranged, and the buffer pad layer is divided into four groups of arc-shaped pad layers.
