High Speed Electrical Connector Shielding Member Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electrical connectors lack support for their shielding members, making them prone to deformation under external forces when mounted on a printed circuit board.
Innovation Solution
The electrical connector design includes an elongated housing with first and second conductive modules, each comprising transmission wafers with insulating frames and shielding members, where the shielding members are retained by retaining structures on the insulating frames, preventing deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the shielding member is fastened to the insulating frame without retaining structures, then the assembly process is simple, but the shielding member is easily deformed by external forces
Solution Approach 1:
The insulating frame is segmented into multiple retaining structures (retaining ribs) that are distributed along the bottom end portion. These segmented retaining structures provide localized support points for the shielding member, enhancing deformation resistance while maintaining assembly simplicity through the modular retaining structure design
Solution Approach 2:
The retaining structures extend in a direction perpendicular to the main mounting direction, creating a three-dimensional support system. The retaining ribs protrude from the bottom end portion of the insulating frame in the height direction, providing support from multiple spatial dimensions to prevent shielding member deformation during mounting
2Device complexity
If the pins of the shielding member are not supported by any component, then the structure is simple, but the pins are easily deformed during mounting
Solution Approach 1:
The retaining structures act as intermediary support elements between the insulating frame and the shielding member pins. These retaining ribs provide intermediate support points that distribute and bear the mounting forces, preventing direct transmission of deformation forces to the pins while maintaining overall structural simplicity
Solution Approach 2:
The retaining structures are pre-configured on the insulating frame before mounting to provide beforehand support and cushioning for the shielding member pins. This prior support structure prevents deformation by absorbing and distributing external forces during the mounting process
