Description

Technical Field

[0001] This utility model belongs to the field of network communication equipment technology, and in particular relates to a Category 5 shielded network cable. Background Technology

[0002] Category 5 shielded network cable is a transmission cable that adds a metal shielding layer (such as aluminum foil) to the Category 5 unshielded network cable. The shielding layer reduces electromagnetic interference and signal crosstalk. It has a transmission frequency of 100MHz, supports a speed of 100Mbps, and can be used for gigabit transmission under auto-negotiation. The transmission distance is usually ≤100 meters, making it suitable for cabling scenarios with complex electromagnetic environments.

[0003] The components include shielded RJ45 connectors, information modules, couplers, etc., all of which use metal shielded shells and are electrically connected to the cable shielding layer to form a complete shielded link. For example, the shielded crystal head is grounded through the metal shell to prevent signal leakage. The shielded module shell is fully shielded 360°. Matching grounding components ensure anti-interference effect. Full-link shielding is required to achieve performance.

[0004] Currently, while existing technologies include five types of shielded network cables and components that can reduce electromagnetic interference and ensure stable signal transmission through metal shielding layers, they still have limitations in actual installation. If the cables are exposed to the outdoors for a long time, continuous sunlight will accelerate the aging of the cable sheath, and friction with objects can easily cause wear on the shielding layer. At the same time, due to the lack of convenient fixing structures, the cables are prone to loosening of connections or breakage of the shielding layer when subjected to force and pulling, which in turn leads to rapid damage to components and affects the stability and service life of network transmission.

[0005] To address the aforementioned issues, this application proposes a Category 5 shielded network cable. Utility Model Content

[0006] The purpose of this invention is to provide a Category 5 shielded network cable, which solves the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model relates to a Category 5 shielded cable, comprising a Category 5 shielded cable with a protective sleeve covering its outer surface. Two sun-protective sleeves are fixedly connected to the outer surface of the protective sleeve. An extension sleeve is slidably connected inside each sun-protective sleeve. A tension limiting ring is fitted onto the outer surface of each sun-protective sleeve. A reinforcing sleeve is slidably connected to the outer surface of the protective sleeve. A fixing sleeve is fixedly connected to the outer surface of the reinforcing sleeve. A rotating sleeve is rotatably connected to the outer surface of the fixing sleeve.

[0009] Furthermore, the left and right ends of the protective sleeve are both fixedly connected to fixing rings, and the inner wall of each fixing ring is fixedly connected to the outer surface of the Category 5 shielded wire.

[0010] Furthermore, two auxiliary plates are fixedly connected to the outer surface of each of the tensioning and limiting rings, and rubber pads are fixedly connected to the front and back of each of the auxiliary plates.

[0011] Furthermore, two push-pull rings are fixedly connected to the outer surface of the reinforcing sleeve, and each push-pull ring has anti-slip holes arranged at equal intervals on its outer surface.

[0012] Furthermore, the outer surface of the reinforcing sleeve is provided with a threaded pin, the end of which near the reinforcing sleeve is threaded through the reinforcing sleeve and abuts against the outer surface of the protective sleeve.

[0013] Furthermore, two connecting plates are fixedly connected to the outer surface of the rotating sleeve, and a connecting frame is fixedly connected to the side of each set of connecting plates that is far apart from each other.

[0014] Furthermore, each of the two connecting frames is provided with two fixing pins on the side that is close to each other, and the ends of each set of fixing pins that are far apart from each other pass through the connecting frame and extend to the outside of the connecting frame.

[0015] This utility model has the following beneficial effects:

[0016] This utility model forms a multi-layered protective structure by setting a PVC protective sleeve, a UV-resistant PVC sunshade sleeve, and a UV-resistant PVC extension sleeve on the outside of the Category 5 shielded cable. The protective sleeve isolates the cable from the external environment, while the sunshade sleeve and extension sleeve block sunlight through their UV-resistant materials. The elastic metal retaining ring tightly hugs and holds the sunshade sleeve against the protective sleeve, allowing for flexible adjustment of the sun protection range and fixing the sleeve position through the elastic force of the metal. This effectively solves the problems of aging and shielding layer damage caused by long-term outdoor exposure of the cable. The reinforced sleeve made of metal tube can reduce local friction and wear, improve the cable's resistance to external pulling force, and prevent loose connections or shielding layer breakage.

[0017] This utility model forms an adjustable fixed structure by rotating a metal fixed sleeve and a metal rotating sleeve through a bearing connection. This structure can adapt to the installation angle requirements of different scenarios and ensure the continuous electromagnetic interference suppression performance through a full-link shielding design.

[0018] In summary, this utility model, through the synergistic design of materials and structure, significantly improves the durability and transmission stability of Category 5 shielded network cables and components in complex environments, providing a solution with both anti-interference and long lifespan for outdoor cabling, industrial communication and other scenarios.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0029] Please see Figure 1-4 As shown, this utility model is a Category 5 shielded wire, including a Category 5 shielded wire 1. The outer surface of the Category 5 shielded wire 1 is covered with a protective sleeve 6. Two sun protection sleeves 2 are fixedly connected to the outer surface of the protective sleeve 6. An extension sleeve 4 is slidably connected inside each sun protection sleeve 2. A tension limiting ring 3 is fitted onto the outer surface of each sun protection sleeve 2. A reinforcing sleeve 5 is slidably connected to the outer surface of the protective sleeve 6. A fixing sleeve 11 is fixedly connected to the outer surface of the reinforcing sleeve 5. A rotating sleeve 12 is rotatably connected to the outer surface of the fixing sleeve 11.

[0030] In this embodiment, the fixed sleeve 11 is securely mounted on the outer surface of the protective sleeve 6 to form a basic fixed support. At the same time, the rotating sleeve 12 can rotate flexibly around the protective sleeve 6. The combination of the two not only ensures the stability of the structural connection, but also gives the component angle adjustment flexibility through the rotation characteristics, so that the overall structure has both installation adaptability on the fixed basis.

[0031] The protective sleeve 6 is fixedly connected to both the left and right ends with fixing rings 8. The inner wall of each fixing ring 8 is fixedly connected to the outer surface of the Category 5 shielded wire 1. In this embodiment, the fixing rings 8 form a rigid connection between the protective sleeve 6 and the two ends of the Category 5 shielded wire 1, which ensures that the protective sleeve 6 will not slide along the wire axis, and the ring structure of the fixing rings 8 can provide physical protection for the shielding layer of the Category 5 shielded wire 1, avoiding wear of the shielding layer caused by relative displacement between the protective sleeve 6 and the wire.

[0032] Each tension limiting ring 3 has two auxiliary plates 17 fixedly connected to its outer surface. Each auxiliary plate 17 has a rubber pad 7 fixedly connected to its front and back. In this embodiment, the auxiliary plate 17 increases the area of ​​force applied by the fingers. Combined with the anti-slip texture of the rubber pad 7, it is convenient for construction personnel to manually pinch or move the tension limiting ring 3 so that it can slide along the sun protection sleeve 2 to adjust the sun protection coverage.

[0033] Two push-pull rings 10 are fixedly connected to the outer surface of the reinforcing sleeve 5. Each push-pull ring 10 has anti-slip holes 9 arranged at equal intervals on its outer surface. In this embodiment, the push-pull rings 10 provide a gripping fulcrum for construction workers. The anti-slip holes 9 increase the contact friction between the fingers and the push-pull rings 10, making it easier to push and pull the reinforcing sleeve 5 to adjust its position when laying the network cable.

[0034] The outer surface of the reinforcing sleeve 5 is provided with a threaded pin 16. The end of the threaded pin 16 near the reinforcing sleeve 5 is threaded through the reinforcing sleeve 5 and abuts against the outer surface of the protective sleeve 6. In this embodiment, by rotating the threaded pin 16, its tip is pressed tightly against the protective sleeve 6, and the reinforcing sleeve 5 is fixed in the designated position of the protective sleeve 6 by friction.

[0035] Two connecting plates 13 are fixedly connected to the outer surface of the rotating sleeve 12. Each pair of connecting plates 13 has a connecting frame 14 fixedly connected to one side away from the other. In this embodiment, the connecting frame 14 is rigidly connected to the rotating sleeve 12 through the connecting plates 13, so that the connecting frame 14 can rotate around the axis of the protective sleeve 6 with the rotating sleeve 12. The extended design of the connecting frame 14 provides an installation interface for external fasteners. When it is necessary to adjust the laying angle of the network cable, the rotating sleeve 12 can drive the connecting frame 14 to rotate to the target position, realizing the flexibility of multi-angle installation. At the same time, the symmetrical structure of the connecting plates 13 ensures that the connecting frame 14 is evenly stressed, avoiding displacement during rotation.

[0036] Two fixing pins 15 are provided on the side of each of the two connecting frames 14 that are close to each other. The ends of each pair of fixing pins 15 that are far apart from each other pass through the connecting frame 14 and extend to the outside of the connecting frame 14. In this embodiment, the connecting frame 14 is connected and fixed to the external fixing structure by means of fixing pins 15. The exposed parts at both ends of the fixing pins 15 can be locked with fasteners such as nuts and washers to ensure a stable connection between the connecting frame 14 and the external structure. The design of double fixing pins 15 forms two-point support, which enhances the torsional strength of the connecting frame 14 and avoids tilting or loosening caused by single-point force. At the same time, the detachable feature of the fixing pins 15 facilitates on-site installation and later maintenance, and improves the engineering applicability of the component.

[0037] Understandably, the outer PVC protective sleeve 6 serves as a basic barrier, isolating the Category 5 shielded network cable 1 from direct environmental damage. Simultaneously, the outer UV-resistant PVC sun-protective sleeve 2 and the extension sleeve 4 form a double sun-protective barrier. Combined with the elastic metal tension limiting ring 3, the sun-protective coverage can be flexibly adjusted according to needs, and the sleeve position can be secured through elastic fastening force, effectively delaying cable aging caused by sunlight and preventing damage to the shielding layer. The metal reinforcing sleeve 5, with its rigid structure and wear-resistant properties, reduces friction loss between the network cable and external objects, enhancing its resistance to external pulling forces. Furthermore, the bearing-driven rotating connection between the metal fixed sleeve 11 and the rotating sleeve 12 provides multi-angle installation flexibility, adapting to diverse scenarios, ensuring the integrity of the entire shielding structure, continuously and efficiently suppressing electromagnetic interference, and providing reliable protection for network transmission in complex environments.

[0038] One specific application of this embodiment is as follows: In use, first, the Category 5 shielded cable 1 is passed through the protective sleeve 6. The sleeve is then fixed to the outer surface of the Category 5 shielded cable 1 by the fixing rings 8 at both ends, ensuring that the protective sleeve 6 will not slide axially. Subsequently, according to the needs of the outdoor wiring scenario, the extension sleeve 4 is slid along the sun protection sleeve 2. The tension limiting ring 3 is moved by the pinching assist plate 17 to adjust the sun protection coverage. Then, the position of the extension sleeve 4 is fixed by the clamping force of the elastic metal tension limiting ring 3, forming a double-layer UV protection structure. During installation, the construction worker can hold the push-pull ring 10 and slide the reinforcing sleeve 5 along the protective sleeve 6, pressing down on the sun protection sleeve 5 by rotating the threaded pin 16. The protective sleeve 6 fixes the reinforcing sleeve 5 in a position prone to friction, using the rigid structure of the metal tube to buffer external scratches. When it is necessary to fix the network cable, the angle of the connecting frame 14 is adjusted by rotating the sleeve 12 around the fixed sleeve 11. Then, the fixing pin 15 is passed through the connecting frame 14 and the external bracket, and locked with the nut to form an adjustable multi-point fixing structure. After the entire link is installed, the protective sleeve 6, the fixed sleeve 11 and other metal structures are electrically connected to the network cable shielding layer to build a complete shielded link, suppressing electromagnetic interference at a transmission frequency of 100MHz. At the same time, the multi-layer protective structure delays cable aging and improves the transmission stability and service life in outdoor scenarios.
