Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network cable structures fail to effectively isolate electromagnetic crosstalk between twisted pairs and external cables, leading to reduced signal transmission efficiency and increased costs due to the need for additional isolation mechanisms.

1Object-affected harmful factors
If a cross-shaped isolation bracket is used to block crosstalk between twisted pairs, then crosstalk interference is effectively prevented, but the complementary effect between complementary twisted pairs is reduced and manufacturing cost increases
Solution Approach 1:
The isolation bracket is segmented into multiple independent isolation units, each corresponding to a specific twisted pair. Each isolation unit includes isolation walls extending from the base plate to divide the internal space into separate channels, preventing crosstalk while maintaining structural simplicity and allowing complementary twisted pairs to remain adjacent for signal enhancement.
Solution Approach 2:
The isolation walls are selectively positioned to provide localized isolation only where needed between non-complementary twisted pairs, while leaving complementary twisted pairs adjacent to each other. This localized approach prevents crosstalk interference without disrupting the complementary effect between paired twisted pairs.
2Device complexity
If a T-shaped isolation bracket is used to isolate crosstalk between twisted pairs, then the complementary effect is maintained, but external crosstalk interference from adjacent cables cannot be effectively avoided
Solution Approach 1:
The isolation bracket employs an asymmetric design with isolation walls of different heights positioned at different locations. The first isolation wall extends higher than the second isolation wall, creating asymmetric shielding that effectively blocks external crosstalk from adjacent cables while maintaining the complementary effect between twisted pairs within the same channel.
Solution Approach 2:
The isolation walls extend in the vertical dimension from the base plate, creating three-dimensional isolation channels. This vertical dimensionality provides effective shielding against external crosstalk from adjacent cables while maintaining horizontal adjacency of complementary twisted pairs for signal complementation.
3Speed
If network cables are densely arranged to increase transmission speed, then network capacity improves, but electromagnetic wave interference between cables increases
Solution Approach 1:
The cable structure segments electromagnetic fields into separate isolated channels using isolation walls, allowing multiple cables to be densely arranged without electromagnetic interference. Each twisted pair resides in its own isolated channel, enabling high-density cable arrangements while maintaining signal integrity and transmission speed.
Solution Approach 2:
The isolation walls act as intermediary barriers between adjacent twisted pairs and cables, blocking electromagnetic waves from propagating between them. This intermediary structure enables dense cable arrangements by mediating the electromagnetic interaction between adjacent cables.

AI summary
A cable structure includes a tubular body, a main spacer, a first spacer, a first protector, a second protector and a plurality of twisted pairs. The tubular body is disposed in the tubular body. The first spacer is substantially perpendicularly connected to the main spacer in a central position. The first protector and the second protector are disposed at two ends of the main spacer. A first channel is formed by the main spacer, the first protector and the second protector, a second channel is formed by the main spacer, the first protector and the first spacer, and a third channel is formed by the main spacer, the second protector and the first spacer. The twisted pairs are disposed in the first channel, the second channel and the third channel.
