Description

Technical Field

[0001] The utility model relates to the technical field of network cables, in particular to the technical field of CAT6A network cables with ultra-long-distance power supply at POE++ level.

Background Art

[0002] CAT6A super six-category shielded network cables are applicable to enterprise networks of all scales, including large commercial centers, data centers, hospitals, schools, etc. The super six-category shielded network cables not only have high speed and high bandwidth, but also have unparalleled anti-interference ability and stability. Traditional network cables are generally used for signal transmission and can supply power through POE over a short distance. The power supply power of the connected devices is relatively low, and it cannot well meet various application scenarios. For CAT6A super six-category network cables in China, most use the S / FTP double-layer shielding structure, with each pair of wires shielded + the total shielding of aluminum-magnesium alloy wires, which can reduce the radiation of external complexity to the network cable. However, on the other hand, the shielding structure also has disadvantages. After the network cable is connected, especially after using POE power supply, the electromagnetic wave will form obvious reflection in the shielding cavity, forming electromagnetic interference to the core wire, thus affecting the transmission performance of the network cable.

The outside of the fine conductor stranded pair is coated with a first aluminum foil shielding layer. The outside of the single strand of the thick conductor stranded pair is coated with a second aluminum foil shielding layer. A sealing edge buckle is arranged at the joint of the second aluminum foil shielding layer. The outside of the second aluminum foil shielding layer is coated with a self-adhesive PET layer. The outside of the self-adhesive PET layer is coated with an inner insulating sheath layer. The outside of the first aluminum foil shielding layer and the self-adhesive PET layer is coated with a braided mesh layer. The outside of the braided mesh layer is coated with an outer insulating sheath layer.

[0005] Preferably, the braided mesh layer is a copper wire braided mesh layer, and the braided mesh layer is fixedly adhered to the inner side of the outer insulating sheath layer.

[0006] Preferably, the sealing edge buckle and the second aluminum foil shielding layer are of an integral structure, and the sealing edge buckle is composed of two reverse hook edges spliced together.
