Interweave Cable Separator Structure for Crush Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional thermoplastic-sheathed cables lack sufficient mechanical integrity, particularly in terms of crush resistance, which is crucial for reliable electrical performance and safety in residential and commercial applications.
Innovation Solution
Incorporating interweave, outer, and ground assembly separators made of materials like paper, folded along creases, between conductors and the jacket of the cable to enhance mechanical integrity, specifically through improved crush resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional thermoplastic-sheathed cables are constructed without additional separators, then the cable structure remains simple and manufacturing cost is low, but the mechanical integrity and crush resistance are insufficient
Solution Approach 1:
The patent introduces assembly separators as intermediary elements positioned between the conductors and the outer jacket. These separators act as mediators that transfer and distribute mechanical stresses, preventing direct compression of the conductors and improving overall crush resistance without fundamentally changing the cable's basic structure
Solution Approach 2:
The cable assembly is segmented into distinct functional zones by introducing separators between the conductor bundle and the outer jacket. This segmentation allows each component to perform its specific function while collectively enhancing the cable's mechanical integrity and crush resistance
2Reliability
If assembly separators are added to enhance mechanical integrity, then crush resistance improves, but manufacturing complexity and production time increase
Solution Approach 1:
The assembly separators are pre-formed and pre-positioned within the cable structure during the manufacturing process. This preliminary action ensures that the separators are already in place before final assembly, reducing on-site complexity and ensuring consistent mechanical integrity without significantly increasing production time
3Strength
If multiple types of separators (interweave, outer, ground) are incorporated, then structural integrity under stress is maximized, but the number of components and assembly steps increase
Solution Approach 1:
Different types of separators (interweave, outer, ground) are strategically placed at specific locations within the cable assembly where different mechanical stresses are expected. This local quality approach ensures that each separator type addresses the specific structural needs of its position, maximizing overall structural integrity with minimal component variety

AI summary
A cable with a conductor assembly separator may be provided. The cable may comprise an assembly, a jacket, and a conductor assembly separator comprising an interweave assembly separator. The assembly may comprise a first conductor, a second conductor, and a ground. The interweave assembly separator may be disposed between the first conductor and the ground, the second conductor and the ground, a first side of the assembly and the jacket, and a second side of the assembly and the jacket.
