Terminal Assembly Asymmetry for Signal Integrity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional connectors fail to achieve excellent signal integrity (SI) performance due to the equal width of ground and signal terminals, which leads to inadequate shielding and signal energy loss.
Innovation Solution
A terminal assembly with alternately arranged ground and signal terminals, where the ground terminals have additional ground assembling pins to increase their width, effectively shielding the signal terminals and enhancing SI performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the width of ground terminal is made equal to the width of signal terminal for simplified manufacturing, then the manufacturing complexity is reduced, but the signal integrity performance deteriorates due to inadequate shielding
Solution Approach 1:
The patent applies asymmetry by making the ground terminal width different from the signal terminal width. Specifically, the ground terminal includes additional ground assembling pins that extend beyond the signal terminal boundaries, creating an asymmetric structure where the ground terminal is wider than the signal terminal. This asymmetric design provides enhanced shielding for the signal terminal while maintaining manufacturing feasibility through standardized pin configurations.
2Reliability
If additional ground assembling pins are added to increase ground terminal width for better shielding, then the signal integrity performance is improved, but the device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the ground terminal into multiple functional segments: the main ground terminal body and multiple ground assembling pins. These pins are arranged in a segmented pattern around the signal terminal, with some pins positioned at corners and others at midpoints of sides. This segmented approach allows the ground terminal to provide comprehensive shielding coverage without requiring a monolithic complex structure, as each pin segment independently contributes to the overall shielding effect.
