Connector Assembly Shield Ring for EMI Shielding and Easy Molding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connector assemblies face challenges in preventing external electromagnetic interference (EMI) due to their metal housing, which complicates molding and processing, and they often require a non-metal material to address this issue while maintaining electrical connectivity.
Innovation Solution
A connector assembly with a main housing made of non-metal material, a shield case and a shield ring connected to a metal frame, where the shield ring electrically connects the metal frame to the shield case to block EMI, using a combination of non-metal and metal components for efficient EMI shielding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a metal housing is used for the connector assembly, then EMI shielding is effective, but molding and processing become difficult
Solution Approach 1:
The connector assembly uses a composite structure combining non-metal main housing material with metal shield case and shield ring components. This allows the main housing to be easily molded while the metal shielding components provide EMI protection, resolving the contradiction between ease of manufacture and EMI shielding effectiveness.
2Ease of manufacture
If a non-metal main housing is used, then molding and processing become easier, but EMI shielding capability is reduced
Solution Approach 1:
The invention combines non-metal main housing with metal shield case and shield ring to create a composite structure that maintains ease of molding while restoring EMI shielding capability through the metal components.
Solution Approach 2:
The housing is segmented into non-metal main housing components and metal shielding components (shield case and shield ring). This segmentation allows each part to be optimized for its specific function - the main housing for ease of molding and the metal components for EMI shielding.
3Object-affected harmful factors
If metal components are used for shield case and ring, then EMI shielding is improved, but device complexity increases
Solution Approach 1:
The shielding function is segmented into separate metal components (shield case and shield ring) that can be independently manufactured and assembled, making the complex EMI shielding requirement manageable through modular design.
Solution Approach 2:
The shield ring acts as an intermediary component that electrically connects the metal frame to the shield case, simplifying the overall connection architecture while maintaining effective EMI shielding through proper electrical continuity.
