Porous Insulating Medium Structure for Stable High-Speed Cables
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-speed cables face a challenge in balancing structural stability with signal transmission attenuation, as gaps within the shielding layer lead to poor stability and performance variation when bent or twisted, while a fully filled interior with insulating medium results in significant signal loss.
Innovation Solution
The insulating medium structure incorporates axially symmetric pores, allowing for a balance between structural stability and reduced signal attenuation by maintaining an air-filled internal structure, similar to a lotus root core design, ensuring mechanical strength and effective signal transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If gaps are formed inside the shielding layer with air as transmission medium, then signal transmission attenuation is reduced, but structural stability deteriorates and performance varies when bent or twisted
Solution Approach 1:
The insulating medium is designed with a porous structure containing multiple air cavities distributed throughout the material body. This allows the medium to maintain structural integrity and stability while containing air regions that reduce signal transmission attenuation. The porous structure combines the mechanical strength of solid material with the electrical benefits of air as transmission medium.
Solution Approach 2:
The insulating medium employs a composite structure combining solid insulating material and air cavities. This composite approach leverages the mechanical strength and stability of the solid material while utilizing the low attenuation properties of air for signal transmission, achieving both structural stability and reduced signal loss simultaneously.
2Stability of the object's composition
If the interior of the shielding layer is completely filled with insulating medium, then structural stability is optimized, but signal transmission attenuation increases significantly
Solution Approach 1:
The insulating medium is designed with a porous structure containing multiple air cavities distributed throughout the material body. This allows the medium to maintain structural integrity and stability while containing air regions that reduce signal transmission attenuation. The porous structure combines the mechanical strength of solid material with the electrical benefits of air as transmission medium.
Solution Approach 2:
Different regions of the insulating medium have different properties: solid material regions provide structural support and stability, while air cavity regions minimize signal attenuation. This local differentiation of material properties allows the insulating medium to simultaneously achieve structural stability and low signal loss by optimizing each region for its specific function.

AI summary
Disclosed are an insulating medium structure and a high-speed cable, the insulating medium structure includes an insulating medium body and pores, where the pores include a first pore and a second pore, a pair of the first pores are formed in the insulating medium body and arranged in an axially symmetric manner, and used for passing a pair of conductors as a differential pair; and at least three second pores are formed in the insulating medium body, and each of the second pores are arranged in an axially symmetric manner relative to a symmetry axis of the pair of the first pores. By preparing the insulating medium into a structure having pores, the insulating medium structure is conducive to ensuring the structural stability of the high-speed cable, thereby avoiding the problem of performance variation of the high-speed cable when being bent and twisted, and reducing signal transmission loss and attenuation.
