Description

Technical Field

[0001] The utility model relates to the technical field of glass optical fibers, in particular to a high-transmittance multi-component glass optical fiber. Background Art

[0002] High-transmittance multi-component glass optical fiber is an optical fiber composed of a combination of multiple glass materials to optimize its optical performance. By carefully selecting different components, this optical fiber can achieve high transmittance within a specific wavelength range (especially the short wavelength region), thereby effectively transmitting optical signals and reducing optical loss. In addition, its design gives the optical fiber a small numerical aperture, which enables it to achieve more precise light beam transmission and is suitable for high-resolution imaging, narrow range lighting, and various optical sensor applications. High-transmittance multi-component glass optical fiber has broad application potential in modern science and technology, medical imaging, industrial detection and other fields.

[0003] Existing glass optical fibers are usually protected by a rubber sheath. The rubber sheath is relatively simple, and the overall toughness of the glass optical fiber is poor. When the glass optical fiber is used, it is prone to excessive bending, which makes the glass optical fiber easily damaged, affecting the long-term use of the glass optical fiber. To this end, we propose a high-transmittance multi-component glass optical fiber. Utility Model Content

[0004] The purpose of the present invention is to provide a high-transmittance multi-component glass optical fiber to solve the problem in the above-mentioned background art that the rubber sheath is simple in configuration but has poor toughness.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a high-transmittance multi-component glass optical fiber, comprising an outer sheath, a multi-layer inner sheath arranged inside the outer sheath, an inner lining layer arranged inside the multi-layer inner sheath, an optical fiber body arranged inside the inner lining layer, side pieces embedded in the side walls of the multi-layer inner sheath, a bending strip arranged inside the side pieces, and a plurality of rubber strips arranged on the side walls of the bending strip.

[0006] Preferably, the multi-layer inner skin includes a first rubber layer, a breathable membrane, a second rubber layer, a heat-insulating membrane and a third rubber layer.

[0007] Preferably, the breathable membrane is arranged between the first rubber layer and the second rubber layer, and the heat-insulating membrane is arranged between the second rubber layer and the third rubber layer.

[0008] Preferably, the side wall of the side piece is provided with a wire coil, and the inside of the side piece is provided with a cavity that matches the bending strip.

[0009] Preferably, a wire mesh is embedded in the inner lining layer.

[0010] Preferably, the bending strip has a wavy structure, and the bending strip and the side piece are of equal length.

[0011] Preferably, the side pieces are fitted into the interior of the outer skin, and the side pieces are in a rectangular parallelepiped structure.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The present invention provides side members between the outer skin and the multi-layer inner skin, and provides bending strips and rubber strips that cooperate with the bending strips inside the side members. When the glass optical fiber bends, the bending strips can be deformed inside the side members in coordination with the bending strips. The deformation of the bending strips in the cavity inside the side members can thereby enhance the overall toughness of the glass optical fiber, prevent the glass optical fiber from being excessively bent, and protect the glass optical fiber.

[0014] 2. The present invention simultaneously utilizes the multi-layer structure inside the multi-layer outer skin and the silk mesh inside the inner lining layer, and utilizes the silk mesh and the multi-layer structure to enhance the overall puncture resistance of the glass optical fiber, thereby solving the problem that common glass optical fibers have a simple outer skin but poor puncture resistance, and is conducive to the long-term use of high-transmittance multi-component glass optical fibers.
