Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors with shielding members suffer from weak electromagnetic interference (EMI) shielding due to gaps between the vertical ground plate and the outer shielding shell, leading to inadequate EMI protection.
Innovation Solution
An electrical connector design that includes a conductive member positioned between the ground plate and the shielding shell to fill the gap, enhancing EMI shielding by using an insulative housing, a shielding shell, a ground plate, and conductive members to prevent EMI leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a gap is maintained between the ground plate and the shielding shell, then assembly is easier and manufacturing is simpler, but EMI shielding performance deteriorates
Solution Approach 1:
A conductive member is introduced as an intermediary element between the ground plate and the shielding shell. This conductive member fills the gap that would otherwise exist between these two components, providing continuous EMI shielding while still allowing for simple assembly. The conductive member acts as a mediator that maintains electrical continuity without requiring precise manufacturing tolerances between the ground plate and shielding shell.
2Object-affected harmful factors
If the gap between ground plate and shielding shell is reduced to improve EMI shielding, then shielding performance improves, but manufacturing precision requirements increase
Solution Approach 1:
The conductive member serves as a compensating intermediary that eliminates the need for tight gap control between the ground plate and shielding shell. By placing this conductive material in the gap, the system achieves effective EMI shielding without requiring high manufacturing precision for the gap dimension itself.
Solution Approach 2:
The solution changes the physical state or form of the gap-filling approach. Instead of relying on precise dimensional control to minimize the gap, the invention introduces a conductive material that can adapt to the gap space, effectively changing the parameter from a dimensional constraint to a material property solution.
