High-Speed Connector Shielding via Ground Terminal Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-speed connectors face challenges in achieving effective shielding to prevent signal cross-talk, as existing ground plates spaced apart and arranged separately do not provide a sufficient shielding effect.
Innovation Solution
A connector design featuring an insulating body with terminal modules and a shielding member, where the shielding member is inserted through holes in the insulating blocks of the ground terminal modules to couple with the ground terminals, enhancing the grounding area and shielding effect without interfering with signal terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If ground plates are spaced apart and arranged separately, then the structure is simple and easy to manufacture, but the shielding effect is insufficient and signal cross-talk increases
Solution Approach 1:
The patent combines multiple ground terminals into a unified ground terminal assembly with an integrated insulating body, merging previously separate ground plates into a single coordinated structure that provides continuous shielding coverage while maintaining manufacturing simplicity
Solution Approach 2:
The insulating body acts as an intermediary that connects multiple ground terminals while providing structural support and electrical isolation, enabling the ground terminals to work together as a unified shielding system without direct metal-to-metal contact
2Ease of manufacture
If ground plates are arranged separately, then manufacturing is easier, but signal cross-talk between adjacent signal terminals increases
Solution Approach 1:
By merging ground terminals into a coordinated assembly with shared insulating support, the design achieves continuous shielding coverage that effectively blocks signal cross-talk while maintaining ease of manufacture through modular assembly
Solution Approach 2:
The ground terminals are arranged in a multi-dimensional configuration around the signal terminals, creating a three-dimensional shielding network that more effectively blocks electromagnetic interference compared to traditional planar ground plate arrangements
