Description

Technical Field

[0001] This utility model relates to the field of optical fiber technology, specifically to an optical fiber structure with a reinforcing coating layer. Background Technology

[0002] The primary function of optical fiber is to transmit data via total internal reflection. Optical fibers are made of glass or plastic, and their internal structure includes a core, cladding, and protective sheath. The core has a high refractive index, while the cladding has a lower refractive index, allowing light to undergo total internal reflection within the core, thus transmitting data along the fiber. However, existing optical fiber structures are simple, resulting in poor tensile strength and susceptibility to damage, affecting usability. Furthermore, the protective sheath of optical fibers is typically black, leading to poor visibility and increasing the risk of multiple fibers crossing over during use. Utility Model Content

[0003] To address the technical problems existing in the background art, this utility model proposes an optical fiber structure with a reinforcing coating layer.

[0007] Preferably, the cladding surface is coated with a PEEK solution, and the PEEK solution condenses on the cladding surface to form an elastic reinforcing coating layer. Through the above improvements, the PEEK solution is coated on the cladding surface and then solidified on the cladding surface using a heating and drying device to form a reinforcing coating layer, thereby protecting the internal fiber core and significantly improving the structural strength and tensile strength of the optical fiber.

[0010] Preferably, a reinforcing steel wire is inserted into the protective part, thereby improving the overall structural strength of the optical fiber.

[0011] Preferably, the diameter of the reinforcing steel wire is 1.2 mm. Through the above improvements, it has higher structural strength and improves the service life of the optical fiber compared with the traditional 1.0 mm steel wire.

[0012] Preferably, the protective part is arranged in an arc shape, one of the protective parts is entirely in a first color, and the other protective part is entirely in a second color. Through the above improvements, the two protective parts are joined together to form a protective sleeve, one of the protective parts is in the first color, and the other protective part is entirely in the second color, for example, one is black and the other is red, thereby greatly improving the recognizability.

[0013] Preferably, the protective part is arranged in an arc shape, and the protective parts are partially joined to form a joint gap between the protective parts. The joint gap is filled with a filling joint part, and the filling joint part has a first color, while the protective part has a second color. Through the above improvement, the filling joint part is filled in the joint gap between the protective parts, thereby improving the reliability of the joint between the protective parts and improving the structural strength of the overall sheath. In addition, the filling joint part has a first color and the protective part has a second color, which also improves the visibility.

[0014] Preferably, a connecting portion is formed between the protective portions, the cladding is placed in the connecting portion, and the connecting portion has a first color and the protective portion has a second color. Through the above improvement, the protective portions are connected by the connecting portion, thereby ensuring structural strength. In addition, the connecting portion has a first color and the protective portion has a second color to ensure recognizability.

[0015] Compared with the prior art, the present invention has the following advantages and beneficial effects: By setting a reinforcing coating layer on the cladding surface, the protection of the fiber core is improved, and the tensile strength and structural strength of the optical fiber are increased. Furthermore, a first area with a first color and a second area with a second color are set on the sheath to improve the identification of the optical fiber and prevent multiple optical fibers from being intertwined and unable to be separated.

[0032] Example 2

The metal braided wires are three-dimensionally woven to form the structural reinforcement layer. The metal braided wires are woven into a metal mesh using a three-dimensional braiding device, and the metal mesh is placed around the outer periphery of the reinforcing coating layer to form the structural reinforcement layer, thereby further improving the structural strength of the optical fiber.
