Electrical Connector Shielding Loop Crosstalk Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors suffer from crosstalk during signal transmission due to unconnected shielding sheets, which limits their shielding effectiveness.
Innovation Solution
The electrical connector design includes electrically connected first and second shielding sheets within each terminal group, with the second shielding sheet of one group connected to the first shielding sheet of an adjacent group, forming a larger ground loop to reduce crosstalk.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If shielding sheets are used to shield signal terminals, then shielding effect is improved, but crosstalk occurs when shielding sheets are not electrically connected
Solution Approach 1:
The patent merges multiple separate shielding sheets into a unified electrically connected system. The first and second shielding sheets within each terminal group are electrically connected, and the first shielding sheet of one terminal group is electrically connected to the second shielding sheet of an adjacent terminal group, forming a continuous ground loop that eliminates crosstalk while maintaining shielding effectiveness.
2Object-affected harmful factors
If multiple shielding sheets are used for each terminal group, then shielding coverage is improved, but manufacturing complexity increases
Solution Approach 1:
The patent combines multiple shielding sheets into a single integrally formed component. The first and second shielding sheets are connected through extending portions that are formed as one piece, eliminating the need for separate assembly steps and reducing manufacturing complexity while maintaining comprehensive shielding coverage.
Solution Approach 2:
The shielding structure is segmented into functional regions (first shielding sheet for one side, second shielding sheet for another side) that are nevertheless integrally formed and electrically connected, allowing each region to perform its specific shielding function while maintaining overall structural simplicity and ease of manufacturing.
