Signal Transmission Component Thin Portion Connector Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional signal transmission components with external connectors are thick, making them cumbersome to connect to mother substrates and reducing connection reliability, and when connectors are omitted, joining processes become complicated and unreliable.
Innovation Solution
A signal transmission component with a laminate structure featuring a thin portion for connector placement, reducing overall thickness and improving connection reliability by directly mounting the connector on the signal conductor, while maintaining desired characteristic impedance and minimizing transmission loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a connector for external connection is arranged on the surface of the laminate, then connection reliability is improved, but the thickness of the signal transmission component increases
Solution Approach 1:
The connector is arranged on a thin portion of the laminate where the thickness is reduced by not providing a ground conductor, allowing the connector to be positioned on the surface without increasing the overall thickness of the signal transmission component
Solution Approach 2:
A thin portion is created locally on the laminate by omitting the ground conductor in that specific region, while the rest of the laminate maintains its full thickness with both ground conductors present, enabling connector placement without compromising overall structural integrity
2Length of moving object
If no connector for external connection is provided, then the thickness of the signal transmission component is reduced, but joining process becomes complicated and connection reliability decreases
Solution Approach 1:
The connector is positioned on the surface of the thin portion rather than being embedded within the laminate thickness, simplifying the joining process while maintaining reduced overall thickness
Solution Approach 2:
The thin portion with exposed signal conductor provides a localized area for simplified connector attachment, while the rest of the structure maintains its protective grounding configuration

AI summary
A signal transmission cable as a signal transmission component includes a laminate including a first thin portion on one of the opposite ends in a first direction and a second thin portion on the other end in the first direction. A portion between the first thin portion and the second thin portion in the laminate is a main line portion. The thickness of the first and second thin portions is thinner than the thickness of the main line portion. The surface on one end in the thickness direction of the laminate defined by the main line portion and the first and second thin portions is a continuous flat surface. A connector for external connection is arranged on the surfaces of the first and second thin portions, on the sides in which each of the thin portions and the main line portion have a difference in level.
