Description

Technical Field

[0001] The utility model relates to the technical field of network cables, in particular to an anti-interference category 7 network cable. Background Art

[0002] Category 7 network cable is a high-performance network cable, usually used to support high-speed data transmission and network connection. In terms of anti-interference, most network cables currently adopt a double-shielded design, which contains two layers of shielding inside, namely, each twisted pair shielding and overall shielding. This design can effectively reduce external interference and provide more stable signal transmission. However, this anti-interference measure is insufficient in some occasions. It is also possible to improve its anti-interference ability by setting a magnetic ring, but most of the existing magnetic rings use ferrite magnetic rings, which require special equipment to be added in their production, and there are certain problems with the production integration with existing network cables. Removable magnetic rings can also be used. This magnetic ring is usually composed of two half rings, which can be clamped on the cable and are easy to install and disassemble. However, since they are two separate parts, there may be some gaps, which may cause some electromagnetic interference to pass through. In addition, it is often not possible to achieve a tight combination with the network cable, and it is easy to slip during use, causing unexpected risks. Utility Model Content
