Shielding Elastic Piece Structure for Stable Connector EMI Contact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional connectors with elastic pieces for shielding electromagnetic interference (EMI) often experience poor and unstable performance due to inadequate contact between the elastic piece and the casing, leading to ineffective shielding.
Innovation Solution
A connector design featuring a housing with an outer shielding elastic piece that includes first and second contacting bumps, forming an angle, which is secured to the housing and contacts both the inner and outer surfaces of a mating connector, ensuring stable electromagnetic shielding by forming a frame configuration and electrical connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a local component of the elastic piece is connected to the casing to increase electromagnetic shielding performance, then the shielding performance is improved, but the contact between the elastic piece and the casing becomes poor or unstable
Solution Approach 1:
The elastic piece is designed to be deformable and adaptable, allowing it to dynamically adjust its shape to fit the housing cavity and maintain stable contact. The elasticity enables the piece to compensate for dimensional variations and ensure reliable electrical connection while maintaining shielding effectiveness.
Solution Approach 2:
The elastic piece features locally differentiated structures including protruding portions with contacting bumps at specific positions. These localized contacting bumps are designed to engage with corresponding recesses on the housing, creating reliable contact points while the rest of the elastic piece maintains its shielding function.
2Reliability
If the elastic piece is designed to contact both inner and outer surfaces of the mating connector, then the shielding stability is improved, but the device complexity increases
Solution Approach 1:
The elastic piece serves multiple functions simultaneously: it provides electromagnetic shielding, maintains electrical connection through contacting bumps, and adapts to fit the housing cavity. This multi-functionality is achieved through a single integrated component rather than multiple separate parts, thereby improving shielding stability without proportionally increasing complexity.
Solution Approach 2:
The elastic piece functions as a flexible shielding element that can deform to contact both inner and outer surfaces of the mating connector. This flexibility allows a single thin-walled component to achieve multiple contact points and maintain reliable shielding without requiring a complex rigid structure.
