Description

Technical Field

[0001] This utility model relates to the field of Category 5e data cable technology, specifically to a high-reliability Category 5e data cable. Background Technology

[0002] Category 5e data cable is a type of communication cable. Category 5e cable refers to Category 5e unshielded twisted pair (UTP) and shielded twisted pair (STP), which is an upgraded version of Category 5 cable. Category 5e data cables are cables that have improved upon some performance aspects of existing Category 5 data cables. Many performance parameters, such as near-end crosstalk, attenuation-to-crosstalk ratio, and return loss, have been improved. A search revealed existing technology (publication number: CN202121630899.7) for high-reliability Category 5e data cables. The paper states that "the serrated structure on the inner side of the sheath increases the friction between the sheath and the shielding layer, making the shielding layer relatively fixed, thereby stabilizing the position of the components inside the sheath and providing a physical structural basis for preventing signal interference. The shielding layer in this disclosure uses aluminum foil, providing reliable resistance to external crosstalk. Through the above special structural design, the core pairs are relatively fixed, reducing crosstalk and maintaining impedance stability, ensuring high reliability of data transmission." However, the aluminum foil shielding layer in existing Category 5e data cables has relatively weak mechanical strength, making it prone to wear against the metal braided layer, leading to a decrease in cable shielding effectiveness. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, a high-reliability Category 5e data cable is provided to solve the problem that the metal aluminum foil shielding layer of existing Category 5e data cables has weak mechanical strength and is prone to wear with the metal braided layer, resulting in a decrease in the cable shielding effect.

[0004] To achieve the above objectives, a high-reliability Category 5e data cable is provided, comprising: a data cable body, wherein the data cable body includes an outer structural layer and twisted-pair cores.

[0005] The outer surface of the twisted pair core is provided with a PI resin sheath layer. The inner side of the cable outer structural layer is wrapped with a Mylar tape layer. The outer surface of the data cable body is provided with an umbrella-shaped support. The outer surface of the Mylar tape layer is bonded with a conductive cloth layer. The outer surface of the conductive cloth layer is wrapped with a polyetheretherketone (PEEK) reinforcing layer. The outer end of the PEEK reinforcing layer is provided with a polyester waterproof layer. A copper wire braided mesh layer is provided between the PEEK reinforcing layer and the polyester waterproof layer.

[0006] Furthermore, the outer structural layer of the cable includes a polyvinyl chloride surface layer, a polyester waterproof layer, a polyetheretherketone reinforcing layer, a conductive cloth layer, a Mylar tape layer, and a copper wire braided mesh layer.

[0007] Furthermore, umbrella-shaped support strips are equidistantly bonded to the outer surface of the polyvinyl chloride surface layer.

[0008] Furthermore, the inner surface of the polyvinyl chloride layer is wrapped and bonded to the polyester waterproof layer.

[0009] Furthermore, the twisted pair core includes a conductor, an insulation layer, and a PI resin sheath layer.

[0010] Furthermore, the conductor surface is covered with an insulating layer.

[0011] Furthermore, two coiled conductors are provided on the inner side of the PI resin sheath layer.

[0012] The beneficial effects of this utility model are as follows: the high-reliability Category 5e data cable of this utility model utilizes a PI resin sheath layer, a conductive cloth layer, and a copper wire braided mesh layer to form multiple inner and outer shielding layers for the Category 5e data cable. This facilitates efficient shielding and resistance to external electromagnetic interference, ensuring the stability and accuracy of signal transmission in the Category 5e data cable. Furthermore, the umbrella-shaped support strips on the surface of the Category 5e data cable and the inner polyetheretherketone (PEEK) reinforcing layer further enhance the mechanical strength of the Category 5e data cable, ensuring the structural safety and stability of the Category 5e data cable, extending its service life, and improving its high reliability.

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.

[0019] Reference Figures 1 to 4 As shown, this utility model provides a high-reliability Category 5e data cable, including: a data cable body 1, which includes an outer structural layer 2 and twisted pair cores 3.

[0020] The outer surface of the twisted pair core 3 is provided with a PI resin sheath layer 33. The inner side of the cable outer structural layer 2 is wrapped with a Mylar tape layer 8.

[0021] The data cable body 1 consists of multiple shielding layers, including a PI resin sheath layer 33, a conductive cloth layer 7, and a copper wire braided mesh layer 9, forming a Category 5e data cable. This facilitates efficient shielding and resistance to external electromagnetic interference, ensuring the stability and accuracy of signal transmission in the Category 5e data cable. Furthermore, the umbrella-shaped support strips 4 on the surface of the data cable body 1 and the inner polyetheretherketone (PEEK) reinforcing layer 7 further enhance the mechanical strength of the Category 5e data cable, ensuring its structural safety and stability, extending its service life, and improving its high reliability.

[0022] In this embodiment, the outer structural layer 2 of the cable includes a polyvinyl chloride (PVC) surface layer 21, a polyester waterproof layer 5, a polyetheretherketone (PEEK) reinforcing layer 6, a conductive cloth layer 7, a Mylar tape layer 8, and a copper wire braided mesh layer 9. Umbrella-shaped support strips 4 are equidistantly bonded to the outer surface of the PVC surface layer 21. The inner surface of the PVC surface layer 21 is wrapped and bonded to the polyester waterproof layer 5.

The Mylar tape layer 8 is coated with a single-layer anti-interference coating. The conductive cloth layer 7 and the copper wire braided mesh layer 9 possess excellent anti-interference performance, effectively resisting external electromagnetic interference and ensuring the stability and accuracy of signal transmission in the data cable body 1. Thermally conductive fillers are added to the polyester waterproof layer 5, facilitating waterproofing while allowing the cable's heat to be conducted and dissipated outwards.

[0024] In this embodiment, the twisted pair core 3 includes a conductor 31, an insulation layer 32, and a PI resin sheath layer 33. The surface of the conductor 31 is covered with the insulation layer 32. Two coiled conductors 31 are disposed inside the PI resin sheath layer 33.

[0025] As a preferred implementation, the PI resin sheath layer 33 serves as an anti-interference structural layer for the wound conductors 31, preventing interference between the multiple sets of twisted pair cores 3 within the data cable body 1, ensuring that the electrical signal is subjected to as little interference as possible during transmission, thereby guaranteeing stable data transmission.

[0026] This utility model of a high-reliability Category 5e data cable effectively solves the problem in existing technologies where the metal aluminum foil shielding layer of Category 5e data cables has weak mechanical strength and is prone to wear with the metal braided layer, leading to a decrease in cable shielding effectiveness.
