Connector Ground Layout for Resonance Shielding in High-Speed Signals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional connectors experience high resonance due to limited return paths for ground terminals, affecting the quality and reliability of high-speed signal transmission.
Innovation Solution
A connector design with multiple ground terminals connected to a conductive member in at least two places, featuring a conductive member and insulating body with a slot for plugging, signal and ground terminals arranged along a direction, and at least two ground terminals between each pair of signal terminals, enhancing the return paths for resonance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional ground terminal configuration with single return path is used, then device complexity is reduced, but shielding effect against resonance is insufficient
Solution Approach 1:
The ground terminal is divided into multiple contact parts (first contact part and second contact part) that connect to the conductive member at different locations. This segmentation creates multiple return paths for ground current, improving shielding effectiveness without requiring a complete redesign of the ground terminal structure
Solution Approach 2:
The conductive member extends in a direction perpendicular to the signal terminals, creating a new dimensional path for ground current return. This vertical dimension adds additional return paths that are independent of the traditional horizontal ground paths, enhancing shielding without increasing planar complexity
2Reliability
If multiple ground terminals are added between signal terminals, then shielding effect is improved, but device complexity increases
Solution Approach 1:
Multiple ground terminals are merged with a single conductive member that serves as a common return path. The conductive member integrates the function of multiple separate ground connections, allowing multiple ground terminals to work together while sharing a unified structural element, thus improving shielding without proportionally increasing overall device complexity
3Reliability
If conductive member is added to provide multiple return paths, then shielding effect is enhanced, but manufacturing complexity increases
Solution Approach 1:
The conductive member serves multiple functions simultaneously: it acts as a ground connection for multiple ground terminals, provides a return path for high-frequency signals, and serves as a structural support element within the connector housing. This multi-functionality reduces the need for additional separate components, simplifying manufacturing despite the enhanced shielding capability
