However, the existing light-conducting optical fiber is limited by its own structure and installation position in the optical fiber cable, which makes it difficult to install the light-conducting optical fiber into the brancher, thereby causing difficulty in searching for a line.

[0026] To solve the above problems, the present application provides an optical fiber connector, which aims to solve the problem that the light-conducting optical fiber in the existing optical fiber connector is difficult to install into the brancher, thereby causing difficulty in searching for a line.

[0027] As Figure 1In an embodiment, the optical fiber connector comprises an optical fiber cable and two branchers, the optical fiber cable comprises a transmission optical fiber 10, a light guide optical fiber 20 and a protective sleeve 30, the protective sleeve 30 is sleeved on the transmission optical fiber 10 and the light guide optical fiber 20, the two branchers are installed at two ends of the optical fiber cable, the two branchers are provided with mounting portions, the light guide optical fiber 20 is located at an inner side edge of the protective sleeve 30 close to the mounting portion, and one end of the light guide optical fiber 20 is inserted into one mounting portion.

[0028] In the embodiment, the transmission optical fiber 10 is responsible for signal transmission, ensures normal use of the optical fiber connector, and the material of the protective sleeve 30 can be selected from polyvinyl chloride or polyethylene, so that the protective sleeve 30 has good wear resistance, corrosion resistance and flame retardance, so as to prevent the transmission optical fiber 10 and the light guide optical fiber 20 from being damaged externally and improve the service life of the optical fiber cable. The light guide optical fiber 20 is made of soft transparent material, for example, transparent plastic, which can ensure the light guide efficiency of the light guide optical fiber 20 and make the light guide optical fiber 20 have high flexibility, so that the light guide optical fiber 20 can be bent and inserted into the mounting portion, the shape of the insertion port of the mounting portion is matched with the shape of the light guide optical fiber 20, and the insertion convenience of the light guide optical fiber 20 is further improved. Further, the light guide optical fiber 20 is arranged at the inner side edge of the protective sleeve 30 close to the mounting portion, so that the light guide optical fiber 20 is closer to the mounting portion, and the insertion efficiency of the light guide optical fiber 20 is improved; when the two ends of the light guide optical fiber 20 are inserted into the two mounting portions, only one mounting portion needs to be irradiated by the external light source emitting device, and the other mounting portion can generate a light spot, and then the line searching is completed.

[0029] The utility model provides a kind of optical fiber connector, including optical fiber cable and two branchers, wherein the optical fiber cable includes transmission optical fiber 10, light guide optical fiber 20 and protective sleeve 30 sleeved on transmission optical fiber 10 and light guide optical fiber 20, two branchers are installed at two ends of the optical fiber cable, two branchers are provided with mounting portion, and light guide optical fiber 20 is located at the inner side edge of protective sleeve 30 close to mounting portion, when two branchers are inserted into the two ends of the optical fiber cable, the two ends of light guide optical fiber 20 can be quickly inserted into the mounting portion of brancher, then it is convenient for external light source emitting device to irradiate to light guide optical fiber 20, reduce the difficulty of line searching.

[0030] As Figure 1 In an embodiment, the cross section of the optical fiber cable is circular.

[0031] In the embodiment, the light guide optical fiber 20 is a cylindrical cable, and the circular cross section can ensure uniform light propagation path inside the optical fiber, thereby improving the transmission quality of the optical signal; meanwhile, the circular cross section can make the light guide optical fiber 20 have good strength and flexibility, so as to be bent; meanwhile, the insertion port of the mounting portion is also circular, and the size of the insertion port is matched with the radial size of the light guide optical fiber 20, so as to insert the light guide optical fiber 20 into the mounting portion, thereby improving the line searching efficiency.

[0032] As Figure 1 In an embodiment, the diameter of the light guide optical fiber 20 is D, where 0.6mm<D<0.9mm.

[0033] In the embodiment, on the one hand, the light guide optical fiber 20 needs to be bent and then inserted into the mounting portion, so as to ensure the flexibility of the light guide optical fiber 20, and on the other hand, in order to ensure the light guiding efficiency of the light guide optical fiber 20, the diameter of the light guide optical fiber 20 should not be too small, so the diameter D of the light guide optical fiber 20 is set to be 0.6mm<D<0.9mm, for example, 0.65mm, 0.75mm, 0.85mm, etc.

[0034] As Figure 1 In an embodiment, the light guide optical fiber 20 includes an optical fiber body and a wear-resistant layer, and the wear-resistant layer is wrapped on the outer periphery of the optical fiber body.

[0035] In the embodiment, the optical fiber body plays a role of transmitting light, and the outer periphery of the optical fiber body is wrapped with a wear-resistant layer, which can reduce the damage of the optical fiber body in the use process and under the influence of the working environment, thereby improving the service life of the light guide optical fiber 20. In addition, the setting of the coating layer can also play a certain optical role, reducing the reflection and scattering of the optical fiber body and the external environment, thereby improving the transmission efficiency of the optical signal.

[0036] As Figure 1 In an embodiment, the optical fiber cable includes a first protective layer 40, the first protective layer 40 is wrapped on the outer periphery of the transmission optical fiber 10 and the light guide optical fiber 20, and the protective sleeve 30 is wrapped on the outer periphery of the first protective layer 40.

[0037] In the present embodiment, the optical fiber cable is further provided with a first protective layer 40, which is sleeved on the outer circumferential side of the transmission optical fibers 10 and the light-guiding optical fibers 20 to provide additional mechanical protection and environmental protection to prevent the transmission optical fibers 10 and the light-guiding optical fibers 20 from being physically damaged during installation and use. The thickness of the first protective layer 40 is determined by the number and radial size of the transmission optical fibers 10, and when the number and radial size of the transmission optical fibers 10 are larger, the thickness of the first protective layer 40 is correspondingly increased, and vice versa, the thickness of the first protective layer 40 is correspondingly reduced. The first protective layer 40 and the protective sleeve 30 form a double protection, ensuring the long-term stability and reliability of the optical fiber cable in harsh environments.

[0038] As Figure 1 In an embodiment, the first protective layer 40 is spirally arranged along the axial direction of the transmission optical fibers 10 and the light-guiding optical fibers 20.

[0039] In the present embodiment, since the optical fiber cable often needs to be bent during actual use, the spirally arranged first protective layer 40 can expand along the curved shape when the optical fiber cable is bent, thereby reducing the stress concentration on the internal optical fibers. This design allows the optical fiber cable to withstand a larger bending radius while maintaining its structural integrity without damaging the optical fibers. In addition, the spirally arranged first protective layer 40 can also provide better tensile strength. When the optical fiber cable is subjected to tension, the spiral shape can disperse the stress, thereby protecting the internal optical fibers from damage.

[0040] As Figure 1 In an embodiment, the material of the first protective layer 40 is stainless steel.

[0041] In the present embodiment, the material of the first protective layer 40 is stainless steel, which allows the first protective layer 40 to withstand larger mechanical stresses such as tension, pressure, and bending force. During installation and use of the optical fiber cable, the stainless steel protective layer can effectively prevent the optical fibers from being mechanically damaged externally, such as cutting, abrasion, and extrusion. At the same time, stainless steel has good corrosion resistance, allowing the first protective layer 40 to maintain its structural integrity in various harsh environments, thereby protecting the internal transmission optical fibers 10 and light-guiding optical fibers 20 from corrosion damage.

[0042] As Figure 1 In an embodiment, the optical fiber cable includes a second protective layer 50, which is sleeved between the first protective layer 40 and the protective sleeve 30.

[0043] In the embodiment, the second protective layer 50 is arranged between the first protective layer 40 and the protective sleeve 30, and forms a multi-layer protection system with the first protective layer 40. When the optical fiber cable is subjected to external impact or pressure, the optical fiber cable can disperse and absorb stress through different layers of the protective layer, thereby reducing damage to the internal transmission optical fiber 10 and the light guide optical fiber 20.

[0044] As Figure 1 In an embodiment, the second protective layer 50 is aramid.

[0045] In the embodiment, the material of the second protective layer 50 is aramid, so that the second protective layer 50 itself has good flexibility and tensile strength, so that the optical fiber cable can withstand greater stress when being stretched and bent, thereby protecting the internal optical fiber cable and transmission cable from being damaged, and further improving the service life of the optical fiber cable.

[0046] The above is only an exemplary embodiment of the utility model, and does not limit the patent range of the utility model, and any equivalent structural transformation made by using the utility model specification and the attached drawings, or direct / indirect application in other related technical fields is included in the patent protection range of the utility model.
