Electrical Connector Shielding via Integrated Grounding Net
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connector assemblies for high-speed and high-frequency applications have inadequate shielding, leading to increased interference, and complex structures do not effectively prevent signal interference.
Innovation Solution
An electrical connector assembly with an insulative housing, terminals, and a grounding route on the mating surface, where a shielding device is exposed in receiving holes and electrically connects with the grounding route, forming a matrix of grounding elements around pads on both the chip module and printed circuit board to create a comprehensive shielding network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a complex socket body structure with multiple shielding plates is used, then the shielding coverage is increased, but the device complexity increases and manufacturing becomes more difficult
Solution Approach 1:
The patent combines multiple separate shielding plates into a single integrated shielding plate that spans across multiple receiving holes. This merging approach maintains comprehensive shielding coverage while simplifying the overall structure, reducing the number of components, and easing manufacturing complexity compared to using multiple separate shielding plates for each receiving hole
Solution Approach 2:
The shielding plate is designed to serve multiple functions simultaneously: it provides shielding for multiple receiving holes, acts as a structural support element, and creates a unified grounding path. This multi-functionality reduces the need for additional separate components, thereby simplifying the device while maintaining effective shielding
2Object-affected harmful factors
If multiple separate shielding plates are assembled between adjacent contacts, then shielding coverage is provided, but the manufacturing precision requirements increase
Solution Approach 1:
By merging multiple shielding functions into a single shielding plate, the patent eliminates the need for precise positioning and assembly of multiple separate shielding plates. The unified structure reduces cumulative positioning errors and simplifies manufacturing tolerance requirements, thereby reducing overall manufacturing precision demands while maintaining effective shielding coverage
3Object-affected harmful factors
If grounding elements are placed around each pad, then shielding effectiveness is improved, but the device complexity increases
Solution Approach 1:
The patent merges individual grounding elements into a unified grounding network formed by the integrated shielding plate that connects all grounding elements together. This approach provides comprehensive grounding coverage around all pads while simplifying the overall grounding structure, reducing the number of separate grounding components, and easing assembly complexity
