V-Shape Cable Assembly With Interposing Portion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable assemblies with insulated conductors face challenges in maintaining a predetermined distance between conductors without increasing the size of the cable assembly, particularly when requiring increased spacing, which often necessitates thicker covers and larger assemblies.
Innovation Solution
A cable assembly configuration featuring a first cable, two second cables, coupling portions, an interposing portion, and an outer cover, arranged in a V-shape, where the interposing portion extends along the cables and is in contact with them, allowing for adjustable spacing between conductors without enlarging the assembly's size, and enabling easy replacement or modification to match different characteristic impedances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the cover thickness is increased to maintain a predetermined distance between conductors, then the conductor spacing is improved, but the cable assembly size increases
Solution Approach 1:
An interposing portion is introduced between the first cable and the two second cables to maintain predetermined distances. This intermediary element allows precise conductor spacing control without requiring increased cover thickness, thereby preventing cable assembly enlargement while achieving the required manufacturing precision for differential signal transmission
Solution Approach 2:
The invention transitions from relying solely on cover thickness (one-dimensional solution) to utilizing the interposing portion positioned between cables (spatial arrangement in multiple dimensions). The V-shaped configuration with the interposing portion creates precise conductor spacing through geometric arrangement rather than uniform thickness increase, solving the contradiction between spacing precision and assembly size
2Manufacturing precision
If the cable assembly size is increased to maintain conductor distance, then the conductor spacing is improved, but the compactness deteriorates
Solution Approach 1:
The interposing portion serves as a mediator that enables precise conductor spacing maintenance within a compact form factor. By positioning this element between the cables in a V-shaped arrangement, the invention achieves required manufacturing precision without compromising cable assembly compactness
Solution Approach 2:
The interposing portion is strategically placed only where needed - between the first cable and the two second cables - to maintain predetermined distances locally. This localized intervention achieves the required conductor spacing precision without unnecessarily increasing the overall cable assembly dimensions, preserving compactness

AI summary
A cable assembly extends in a longitudinal direction. The cable assembly comprises a first cable, two second cables, two coupling portions, an interposing portion and an outer cover. The first cable has a first conductor and a first cover. Each of the second cables has a second conductor and a second cover. The coupling portions couple the second covers, respectively, with the first cover. The first cable, the two second cables and the two coupling portions are arranged in a V-shape in a plane perpendicular to the longitudinal direction. The interposing portion extends along the first cable and the two second cables and has a full length which is equal to that of each of the first cable and the two second cables. The interposing portion is brought into contact with all the first cable and the two second cables.
