Segmented Shielded Cable Structure for Stable 60 GHz Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional data transmission cables have low high-frequency test bandwidth and unstable high-frequency performance, requiring inefficient winding of outer and shielding layers, which limits their ability to meet higher-frequency data transmission requirements.
Innovation Solution
The cable features a pair of conductors with a single extruded inner insulating layer and a conductive shielding layer and outer insulating layer arranged in semi-longitudinal circumferential halves, improving fit and stability, and increasing frequency bandwidth to 60 GHz or higher by eliminating conventional wrapping structures and enhancing production efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional winding structure is used for outer insulating layer and shielding layer, then ease of manufacture is improved, but high-frequency test bandwidth is reduced and production efficiency is reduced
Solution Approach 1:
The outer insulating layer and shielding layer are divided into two separate circumferential halves rather than being wound as continuous layers. Each half is positioned and fixed independently, eliminating the winding structure and enabling higher frequency bandwidth while simplifying the manufacturing process through modular assembly.
2Ease of manufacture
If conventional winding structure is used for outer insulating layer and shielding layer, then ease of manufacture is improved, but production efficiency is reduced
Solution Approach 1:
The cable structure is segmented into discrete halves that can be assembled efficiently. The two circumferential halves of the shielding layer and outer insulating layer are positioned and fixed in a streamlined manner, eliminating time-consuming winding operations and significantly improving production efficiency.
3Device complexity
If conventional winding structure is used, then manufacturing process is simplified, but high-frequency performance stability is reduced
Solution Approach 1:
Dividing the shielding and insulating layers into separate halves allows for precise positioning and stable fixation, eliminating the performance instability caused by conventional winding structures. This segmentation provides a more reliable structure for high-frequency data transmission.
4Adaptability or versatility
If winding process is used for outer insulating layer and shielding layer, then manufacturing flexibility is maintained, but production efficiency is reduced
Solution Approach 1:
The segmented half-layer structure maintains manufacturing flexibility by allowing independent positioning and assembly of components, while simultaneously eliminating the time-consuming winding process to achieve high production efficiency.

AI summary
A cable includes a pair of conductors extending longitudinally and spaced apart from each other, an inner insulating layer circumferentially wrapped around an outside of the conductors and fixing the conductors, a conductive shielding layer circumferentially wrapped around an outside of the inner insulating layer, and an outer insulating layer circumferentially wrapped around an outer peripheral surface of the conductive shielding layer. At least one of the conductive shielding layer and the outer insulating layer includes a pair of diametrically opposed circumferential halves. Each circumferential half surrounds a part of a circumference of the inner insulating layer and extends longitudinally.
