Technical Field

[0001] This utility model relates to the field of network cable technology, and in particular to a network cable and connector. Background Technology

[0002] When troubleshooting network cables, it's often necessary to quickly identify both ends of the same cable. Currently, a common method for tracing cables is to insert a light-guiding optical fiber inside the cable, plugging both ends of the fiber into the RJ45 connectors at both ends of the cable. A light source is then used to illuminate the RJ45 connector at one end of the cable, and the other end of the cable is identified by the light spot emitted from the RJ45 connector at the other end.

[0003] However, existing optical fibers are limited by their own structure and installation location within network cables, making it difficult for light source emitting devices to illuminate the optical fibers, which in turn leads to difficulties in tracing the cables. Utility Model Content

[0004] The main purpose of this invention is to propose a network cable that aims to solve the problem that existing light source emitting devices have difficulty illuminating the optical fiber, leading to difficulties in cable tracing.

[0005] To solve the above problems, this utility model proposes a network cable, including a transmission line body twisted together, an optical fiber, and a protective sleeve fitted over the transmission line body and the optical fiber.

[0006] The optical fiber is located on the inner edge of the protective sleeve.

[0007] In one embodiment, the cross-section of the optical fiber is circular.

[0008] In one embodiment, the diameter of the optical fiber is D, wherein 0.6 mm <D<0.9mm。

[0009] In one embodiment, the optical fiber includes an optical fiber body and a coating layer, wherein the coating layer is wrapped around the outer periphery of the optical fiber body.

[0010] In one embodiment, the network cable includes a ground wire and a first shielding layer. The first shielding layer is sleeved on the outer periphery of the optical fiber, the transmission line body, and the ground wire, and the protective sleeve is sleeved on the outer periphery of the first shielding layer.

[0011] In one embodiment, the network cable includes a protective layer that wraps around the outer periphery of the optical fiber and the transmission line body, a first shielding layer that is sleeved on the outer periphery of the protective layer, and a ground wire that is disposed between the protective layer and the first shielding layer.

[0012] In one embodiment, the network cable includes a second shielding layer disposed between the first shielding layer and the protective sleeve.

[0013] In one embodiment, the first shielding layer is made of aluminum foil;

[0014] And / or, the second shielding layer is a woven mesh structure;

[0015] And / or, the protective layer is Mylar.

[0016] In one embodiment, the network cable includes a tear cord disposed between the second shielding layer and the protective sleeve;

[0017] And / or, the network cable includes a plurality of the transmission line bodies, the network cable includes a cross frame, the cross frame is disposed within the protective layer, and the plurality of the transmission line bodies are spaced apart at the four corners of the cross frame.

[0018] This utility model also proposes a connector, including a network cable and two crystal heads. The network cable is the network cable as described above. Each of the two crystal heads has a plug portion at the end away from the network cable. The two crystal heads are respectively installed at both ends of the network cable.

[0030] When troubleshooting network cables, it's often necessary to quickly identify both ends of the same cable. Currently, the common method for tracing cables involves inserting a light-guiding optical fiber inside the cable and connecting both ends to the RJ45 connectors at both ends. A light source is then used to illuminate one RJ45 connector, and the other end of the cable is identified by the resulting light spot. However, the existing optical fiber's structure and its placement within the cable limit its ability to effectively illuminate the light source, making cable tracing difficult.

[0031] To address the aforementioned problems, this utility model proposes a network cable designed to solve the issue that existing light source emitting devices struggle to illuminate the optical fiber, leading to difficulties in cable tracing.

[0032] like Figure 1 In one embodiment, the network cable includes a twisted transmission line body 10, an optical fiber 20, and a protective sleeve 30 sleeved on the transmission line body 10 and the optical fiber 20, with the optical fiber 20 located on the inner edge of the protective sleeve 30.

[0033] In this embodiment, the transmission line body 10 is a twisted pair formed by two insulated copper wires twisted together, which improves the signal transmission quality of the transmission line body 10 itself and reduces external electromagnetic interference to the transmission line body 10. The optical fiber 20 is made of a soft, transparent material, such as transparent plastic, which ensures the light guiding efficiency of the optical fiber 20 and gives it high flexibility, making it easy to insert into the designated position of the external RJ45 connector so that it can be illuminated by an external light source. The protective sleeve 30 can be made of polyvinyl chloride or polyethylene to give it good wear resistance, corrosion resistance, and flame retardancy, preventing external damage to the transmission line body 10 and the optical fiber 20, while further reducing external electromagnetic interference and improving the service life of the network cable. Specifically, the optical fiber 20 is located on the inner edge of the protective sleeve 30, which allows the optical fiber 20 to be closer to the designated insertion position of the external RJ45 connector, improving the insertion efficiency of the optical fiber 20 and thus improving the cable routing efficiency.

[0034] The network cable proposed in this utility model includes a twisted transmission line body 10, a light guide fiber 20, and a protective sleeve 30 sleeved on the transmission line body 10 and the light guide fiber 20. The light guide fiber 20 is located on the inner edge of the protective sleeve 30, and its two ends extend out of the protective sleeve 30. When two crystal heads are inserted into the two ends of the network cable, the two ends of the light guide fiber 20 can be quickly inserted into the crystal heads, which facilitates the external light source emitting device to illuminate the light guide fiber 20 and reduces the difficulty of tracing the cable.

[0035] like Figure 1, in one embodiment, the cross-section of the light guiding optical fiber 20 is circular.

[0036] In this embodiment, the light guiding optical fiber 20 is a cylindrical cable. The circular cross-section setting can ensure a uniform light propagation path inside the optical fiber, thereby improving the transmission quality of the optical signal. At the same time, the circular cross-section enables the light guiding optical fiber 20 to have better strength and stability for bending. The circular cross-section can also make the light guiding optical fiber 20 easily match the corresponding insertion interface on the crystal head, thereby improving the insertion convenience of the light guiding optical fiber 20 and the crystal head and increasing the wire tracing efficiency.

[0037] Such as Figure 1 , in one embodiment, the diameter of the light guiding optical fiber 20 is D, where 0.6mm < D < 0.9mm.

[0038] In this embodiment, on the one hand, the light guiding optical fiber 20 needs to be bent and then inserted into the designated position of the crystal head. Therefore, to ensure the flexibility of the light guiding optical fiber 20 itself, the diameter of the light guiding optical fiber 20 should not be too large. On the other hand, to ensure the light guiding efficiency of the light guiding optical fiber 20 itself, the diameter of the light guiding optical fiber 20 should not be too small. Therefore, the range of the diameter D of the light guiding optical fiber 20 is set to 0.6mm < D < 0.9mm, such as 0.65mm, 0.75mm, 0.85mm, etc.

[0039] Such as Figure 1 , in one embodiment, the light guiding optical fiber 20 includes an optical fiber main body and a coating layer, and the coating layer is wrapped around the outer peripheral side of the optical fiber main body.

[0040] In this embodiment, the optical fiber main body plays a role in transmitting light. The coating layer is wrapped around its outer peripheral side. This coating layer can improve the flexibility of the optical fiber main body itself and further improve the insertion convenience of the light guiding optical fiber 20. At the same time, the setting of this coating layer can play a certain optical role, reducing the reflection and scattering between the optical fiber main body and the external environment, thereby improving the transmission efficiency of the optical signal. In addition, the coating layer can also reduce the wear of the optical fiber main body, thereby increasing the service life of the light guiding optical fiber 20.

[0041] Such as Figure 1 And Figure 2 , in one embodiment, the network cable includes a ground wire 40 and a first shielding layer 50. The first shielding layer 50 is sleeved on the outer peripheral sides of the light guiding optical fiber 20, the transmission line main body 10, and the ground wire 40, and the protective sleeve 30 is sleeved on the outer peripheral side of the first shielding layer 50.

[0042] In this embodiment, the ground wire 40 can be made of copper or other conductive materials. The ground wire 40 provides a grounding path for the network cable, improving its operational safety. The first shielding layer 50 is sleeved on the outer periphery of the optical fiber 20, the transmission line body 10, and the ground wire 40, forming a protective barrier. The first shielding layer 50 further prevents external electromagnetic interference from entering the cable and also prevents signals inside the cable from radiating outward, thereby improving the stability and confidentiality of signal transmission.

[0043] like Figure 1 and Figure 2 In one embodiment, the network cable includes a protective layer 60, which wraps around the outer periphery of the optical fiber 20 and the transmission line body 10. A first shielding layer 50 is sleeved on the outer periphery of the protective layer 60, and a ground wire 40 is disposed between the protective layer 60 and the first shielding layer 50.

[0044] In this embodiment, the protective layer 60 wraps around the outer periphery of the optical fiber 20 and the transmission line body 10 to improve the installation stability of the optical fiber 20 and the transmission line body 10 within the protective sleeve 30, while further reducing wear on the optical fiber 20 and the transmission line body 10 and improving their service life. The ground wire 40 is separately disposed between the protective layer 60 and the first shielding layer 50 to ensure its own grounding function.

[0045] like Figure 1 and Figure 2 In one embodiment, the network cable includes a second shielding layer 70, which is disposed between the first shielding layer 50 and the protective sleeve 30.

[0046] In this embodiment, a second shielding layer 70 is additionally provided between the first shielding layer 50 and the protective sleeve 30. The provision of the second shielding layer 70 further enhances the anti-interference capability of the network cable, making it adaptable to application scenarios with complex electromagnetic environments or extremely high requirements for signal transmission.

[0047] like Figure 1 and Figure 2 In one embodiment, the first shielding layer 50 is made of aluminum foil;

[0048] And / or, the second shielding layer 70 is a woven mesh structure;

[0049] And / or, the protective layer 60 is Mylar.

[0050] In this embodiment, the first shielding layer 50 is made of aluminum foil. Aluminum foil has good conductivity and shielding performance, which can effectively prevent external electromagnetic interference from entering the inside of the network cable and at the same time prevent the signal inside the network cable from radiating outward.

[0051] With or without the above embodiments, the second shielding layer 70 is a metal braided mesh. The metal wires in the metal braided mesh have good conductivity and can absorb and reflect electromagnetic waves, thereby reducing the impact of electromagnetic interference on signal transmission. At the same time, the metal braided mesh is more flexible than a solid metal shielding layer, and can be bent and stretched, making it suitable for cables and equipment that need to be bent or moved. This makes the second shielding layer 70 more convenient to install and can adapt to various complex wiring environments.

[0052] With or without the above embodiments, the protective layer 60 is made of Mylar material, which is a plastic material with good flexibility and abrasion resistance, enabling the protective layer 60 to provide additional physical protection while ensuring the flexibility of the network cable, making it easy to install.

[0053] like Figures 1 to 3 In one embodiment, the network cable includes a tear cord 80, which is disposed between the second shielding layer 70 and the protective sleeve 30;

[0054] And / or, the network cable includes multiple transmission line bodies 10, and the network cable includes a cross frame 90, which is disposed within the protective layer 60, and the multiple transmission line bodies 10 are spaced apart at the four corners of the cross frame 90.

[0055] In this embodiment, the tear cord 80 can be made of nylon or other high-strength fiber materials to give it good abrasion resistance and tensile strength. The tear cord 80 is disposed between the second shielding layer 70 and the protective sleeve 30 to facilitate the stripping of the protective sleeve 30 for easy installation and maintenance of the network cable.

[0056] With or without the above embodiments, the cross frame 90 is a plastic frame to give it good mechanical strength and corrosion resistance. The cross frame 90 is located inside the protective layer 60 and is used to support and separate multiple transmission line bodies 10. The multiple transmission line bodies 10 are spaced apart at the four corners of the cross frame 90 to ensure that there is sufficient spacing between each transmission line body 10 and to reduce crosstalk and signal interference.

[0057] This utility model also proposes a connector, which includes a network cable and two RJ45 connectors. Each RJ45 connector has a plug portion at its end furthest from the network cable. The two RJ45 connectors are respectively installed at both ends of the network cable. One end of a light-guiding optical fiber 20 is inserted into a plug portion. When an external light source emitting device illuminates one of the plug portions, the optical fiber, transmitted through the light-guiding optical fiber 20, causes a light spot to be generated at the other end of the RJ45 connector, thereby completing the cable tracing. The specific structure of this network cable is as described in the above embodiments. Since this network cable adopts all the technical solutions of all the above embodiments, it possesses at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated further here.

[0058] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
