Receptacle Connector Shield Structure for Ground Pad Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Receptacle connectors face challenges in maintaining electromagnetic compatibility (EMC) due to damage from ground springs or ground pads during coupling with plug connectors, leading to buckling and damage of EMC shields.
Innovation Solution
Incorporating a protruding part on the support part of the mold structure that extends in front of the EMC shields, which guides and protects the ground pads of the plug connector, preventing damage to the shields and ensuring secure coupling while maintaining EMC functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the EMC shield is disposed on the support part without additional protective structures, then the device complexity is reduced, but the reliability of the EMC shield is worsened due to damage from ground springs or ground pads during coupling
Solution Approach 1:
The protruding part is formed in advance on the support part to create a protective structure that guides the ground pads during coupling. This preliminary structural preparation prevents damage to the EMC shield before the damaging interaction can occur, resolving the contradiction by adding a simple protective feature rather than complex shielding mechanisms
Solution Approach 2:
The protruding part acts as an intermediary element between the ground pads and the EMC shield. It provides a contact surface for the ground pads, preventing direct contact with the EMC shield and thus protecting it from damage while maintaining the coupling function
2Reliability
If the protruding part is added to guide and protect the ground pads, then the reliability of EMC shield is improved, but the device complexity increases due to additional structural features
Solution Approach 1:
The support part is segmented into distinct functional regions: a flat part for general support and a protruding part for protective guidance. This segmentation allows each region to perform its specific function efficiently while keeping the overall structure simple and manufacturable
Solution Approach 2:
The protruding part is localized at the front end of the support part where the ground pads make contact. This local structural modification provides protection exactly where needed without adding complexity to the entire support part or other regions of the connector
