Twin-Ax Connector Shield Plate Layout for Crosstalk Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connector assemblies fail to effectively suppress crosstalk between twin-ax cables and signal terminal pairs, and they often require multiple shield covers which increase complexity and cost.
Innovation Solution
A connector assembly design that incorporates a single shield plate connected to both the twin-ax cable and the terminal group, providing grounding and shielding, with the shield plate encircling the twin-ax cable to reduce electric field leakage and crosstalk, and using insert molding to integrate the shield plate and terminal group within a frame.

Engineering Contradiction Analysis
1Reliability
If multiple shield covers are used to improve shielding performance, then electrical performance is improved, but device complexity and cost increase
Solution Approach 1:
The patent combines multiple shield covers into a single integrated shield plate structure that provides comprehensive shielding for both the twin-ax cable and terminal group. This merged structure maintains the electrical performance benefits of multiple shields while eliminating the complexity and cost associated with assembling multiple separate components.
Solution Approach 2:
The shield plate is designed to perform multiple functions simultaneously: it shields the twin-ax cable, shields the terminal group, provides grounding connections, and structurally supports both components. This multi-functional design replaces what would traditionally require multiple separate shield covers, reducing overall device complexity while maintaining electrical performance.
