Description

Technical Field

[0001] This utility model relates to the field of network communication cable technology, and in particular to an outdoor high-shield and high-stability communication cable. Background Technology

[0002] With the rapid development of the global information superhighway, local area network (LAN) digital cables have been further applied on a large scale. The rapid growth of network technology and the leapfrog development of access network technology have placed higher demands on information transmission media. Communication cables are cables used to transmit telephone, telegram, fax documents, television and radio programs, data, and other electrical signals. They have advantages such as large communication capacity, high transmission stability, good confidentiality, and less susceptibility to natural conditions and external interference.

[0003] Considering that outdoor communication cables need to meet multiple requirements such as strong anti-interference capability, corrosion resistance, and waterproofing, it is difficult to achieve these requirements using ordinary materials and processes. Currently, the commonly used cable insulation and sheath structures are made of polyolefin-based waterproof and protective layers. The cable cores in this type of cable are generally close together, making them prone to damage under pressure, resulting in weak anti-interference capability and making them susceptible to corrosion or water ingress, thus failing to meet the increasingly complex outdoor usage environment. Furthermore, due to the ultra-thin copper conductors, breakage is likely during copper stranding. Utility Model Content

[0004] To address the aforementioned issues, this invention provides an outdoor high-shield, high-stability communication cable that enhances the electromagnetic interference resistance of the communication cable and effectively protects the copper-clad aluminum core from breakage.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An outdoor high-shield and high-stability communication cable includes an outer protective layer, a stabilizing frame, and a core. The outer protective layer has a first shielding layer embedded within it. The stabilizing frame is disposed within the outer protective layer and includes a plurality of stabilizing components. One end of each stabilizing component is connected to the others and is located at the axis of the outer protective layer. The other end of each stabilizing component faces the outer protective layer, so that adjacent stabilizing components form a cavity, and each cavity is evenly distributed around the perimeter.

[0007] The wire core is provided with several wire cores, and the wire cores are located inside the cavity.

[0008] Furthermore, the outer protective layer includes a PET outer sheath and a PVC outer sheath. The PET outer sheath wraps around the stabilizer, and the outer wall of the PET outer sheath is connected to the inner wall of the first shielding layer. The inner wall of the PVC outer sheath is connected to the outer wall of the first shielding layer.

[0009] Furthermore, the outer diameter of the PVC outer sheath is 6mm; the layer thickness of the PVC outer sheath is 0.3mm.

[0010] Furthermore, the wire core includes an aluminum core, a copper core, and an inner sheath, with the aluminum core embedded inside the copper core and the inner sheath covering and connected to the copper core.

[0011] Furthermore, the inner protective layer includes a PET inner sheath and a second shielding layer. The PET inner sheath covers the copper core and is connected to the copper core, and the second shielding layer covers the outside of the PET inner sheath and is connected to the PET inner sheath.

[0012] Furthermore, the outer diameter of the second shielding layer is 1.3 mm; the thickness of the PET inner sheath is 0.3 mm.

[0013] Furthermore, the diameter of the aluminum core is 0.1-0.13 mm.

[0014] Furthermore, the first shielding layer and the second shielding layer are aluminum foil shielding layers.

[0015] Furthermore, the stabilizer is made of PET material.

[0016] The beneficial effects of this utility model are:

[0017] The stable structure is designed in a star-shaped support structure. By placing the wire core inside the cavity, the wire core does not need to be twisted into copper strands, which effectively protects the wire core from breakage. The first shielding layer effectively prevents external electromagnetic interference from entering and also prevents internal signals from radiating out and interfering with the operation of other parallel wire groups, thus playing a good role in resisting electromagnetic interference and ensuring stable signal transmission of the communication cable. By setting a second shielding layer outside the PET inner sheath, the electromagnetic interference resistance of the communication cable can be further enhanced. Attached Figure Description

[0022] Please see Figure 1 The outdoor high-shield and high-stability communication cable of this preferred embodiment includes an outer protective layer 1, a stabilizing frame 2, and a wire core 3.

[0023] The outer protective layer 1 is embedded with a first shielding layer 101. In this embodiment, the outer protective layer 1 includes a PET outer sheath 11 and a PVC outer sheath 12. The PET outer sheath 11 is wrapped around the stabilizer 2 and is connected to the inner wall of the first shielding layer 101. The inner wall of the PVC outer sheath 12 is connected to the outer wall of the first shielding layer 101.

[0024] The outer diameter of the PVC outer sheath 12 is 6mm; the layer thickness of the PVC outer sheath 12 is 0.3mm.

[0025] The stabilizer 2 is set inside the outer protective layer 1, and the stabilizer 2 includes a number of stabilizers 21. One end of each stabilizer 21 is connected to each other and is located at the axis of the outer protective layer 1. The other end of the stabilizer 21 faces the outer protective layer 1 so that a cavity 211 is formed between adjacent stabilizers 21, and each cavity 211 is evenly distributed around the perimeter.

[0026] In this embodiment, the stabilizer 21 is made of PET material.

[0027] The conductor 3 has several conductors, and the conductor 3 is located inside the cavity 211.

[0028] In this embodiment, the wire core 3 includes an aluminum core 31, a copper core 32 and an inner sheath 33. The aluminum core 31 is embedded in the copper core 32, and the inner sheath 33 covers the copper core 32 and is connected to the copper core 32.

[0029] The stabilizer 2 forms a star-shaped support structure. By placing the wire core 3 within the cavity 211, the wire core 3 does not need to be stranded in copper, effectively protecting it from breakage. Simultaneously, the aluminum core 31 and copper core 32 are tightly bonded together through a precise die-casting process, forming a high-performance copper-clad aluminum composite wire core. This copper-clad aluminum composite wire core design not only optimizes material utilization efficiency but also significantly reduces dependence on expensive copper raw materials, lowering production costs.

[0030] In this embodiment, the inner sheath 33 includes a PET inner sheath 331 and a second shielding layer 332. The PET inner sheath 331 covers the copper core 32 and is connected to the copper core 32. The second shielding layer 332 covers the outside of the PET inner sheath 331 and is connected to the PET inner sheath 331.

[0031] The outer diameter of the second shielding layer 332 is 1.3 mm; the thickness of the PET inner sheath 331 is 0.3 mm.

[0032] The first shielding layer 101 can effectively prevent external electromagnetic interference from entering, and also prevent internal signals from radiating out and interfering with the operation of other parallel line groups, so as to play a good role in resisting electromagnetic interference and ensure the stable signal transmission of the communication cable. By setting a second shielding layer 332 outside the PET inner sheath 331, the electromagnetic interference resistance of the communication cable can be further enhanced.

[0033] Preferably, the first shielding layer 101 and the second shielding layer 332 are aluminum foil shielding layers, and shielding layers made of aluminum foil have the characteristics of high shielding performance.

[0034] The outdoor high-shield, high-stability communication cable in this embodiment is stabilized by a star-shaped support structure 2.

[0035] The stabilizer 2 forms a star-shaped support structure, effectively increasing the stability of the cable; the shielding layer made of aluminum foil has high shielding performance, and the wire made of a composite material of copper-clad aluminum wire core has high stability, low network latency, and low price. The combination of these features results in a highly shielded and stable communication cable with high shielding performance, good stability, low network latency, and low price.
