Terminal Assembly Asymmetric Ground Shielding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional connectors fail to achieve excellent SI performance due to the uniform width of ground and signal terminals, which affects signal transmission and susceptibility to environmental interference.
Innovation Solution
A terminal assembly with alternately arranged ground and signal terminals, where the ground terminals have additional assembling pins increasing their width and the distance between ground and signal assembling pins is smaller than between ground and signal pins, enhancing shielding and signal transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the width of ground terminal is the same as the width of signal terminal, then the manufacturing is simple, but the SI performance is poor
Solution Approach 1:
The ground terminal is designed with asymmetric structure by adding ground assembling pins that extend laterally beyond the signal terminal boundaries. This creates unequal widths where the ground terminal is wider than the signal terminal, providing enhanced shielding capability while maintaining manufacturing simplicity through the modular pin design
2Reliability
If the width of ground terminal is increased to improve shielding, then the SI performance is improved, but the device complexity increases
Solution Approach 1:
The ground terminal is segmented into distinct functional parts: a ground terminal body and multiple ground assembling pins. This segmentation allows the pins to be added as separate modular elements that extend the ground terminal width for better shielding, without complicating the overall manufacturing process or assembly procedure
