Electrical Connector Integrated Metal Shielding Sandwich
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors with separate metallic shells and shielding plates lack sufficient mechanical securing and electrical grounding effectiveness.
Innovation Solution
An electrical connector design featuring an insulative housing with assembled contacts, metallic top and bottom shells, and a metallic shielding plate, where the shells and shielding plate are securely connected via ears to form a sandwiched structure, enhancing mechanical strength and electrical grounding through integrated grounding bars and spring latches.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If separate metallic shells and shielding plate are used, then device complexity is reduced, but mechanical securing and electrical grounding effectiveness deteriorate
Solution Approach 1:
The patent merges the top shell, bottom shell, and shielding plate into a single integrated metal assembly where the shielding plate is sandwiched between the two shells and secured together through welded ears. This combination creates a unified structure that simultaneously provides mechanical protection and electrical grounding without requiring separate mounting operations.
2Ease of manufacture
If separate metallic shells and shielding plate are used, then ease of manufacture is improved, but electrical grounding effectiveness deteriorates
Solution Approach 1:
The metal assembly integrates the shielding plate between top and bottom shells with welded ear connections, creating a pre-assembled unit that maintains electrical grounding integrity while simplifying the overall manufacturing process through single-unit installation.
Solution Approach 2:
The shielding plate is nested between the top and bottom shells, with all three components secured together through welded ears. This nested configuration ensures intimate electrical contact and mechanical bonding, providing effective grounding while maintaining a compact integrated structure.
3Device complexity
If separate metallic shells and shielding plate are used, then device complexity is reduced, but electrical grounding effectiveness deteriorates
Solution Approach 1:
The patent combines the shielding plate with top and bottom shells into a single welded metal assembly, ensuring intimate electrical contact between all components. This merged structure provides superior electrical grounding while maintaining relatively simple device architecture through the integrated design.

AI summary
An electrical connector includes an insulative housing, a plurality of contacts assembled in the housing, opposite metal top and bottom shells attached upon opposite top face and bottom face of the housing, and a metallic shielding plate inserted into the housing and between two rows of contacts. The top shell, the bottom shell and the shielding plate have corresponding ears secured together in an intimately sandwiched manner.
