Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electrical connectors with electromagnetic shields suffer from low performance due to excessive and oversized openings, which compromise their shielding effectiveness during signal transmission.
Innovation Solution
The design incorporates a socket with a grounding part, a first shielding part, a plastic core, and a terminal, where the first shielding part is arranged closely around the plastic core with minimal gap and coupled with a second shielding part to reduce openings, enhancing electromagnetic shielding performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If openings are provided on electromagnetic shields for component assembly, then ease of manufacture is improved, but electromagnetic shielding performance deteriorates
Solution Approach 1:
The shielding structure is divided into multiple segments: grounding part with grounding openings, first shielding part with first openings, second shielding part with second openings, and plastic core with third openings. Each segment has strategically placed openings that allow component assembly while maintaining overall shielding effectiveness through the layered configuration.
Solution Approach 2:
The shielding structure employs nested configuration where the first shielding part is disposed on the grounding part, the second shielding part is coupled to the first shielding part, and the plastic core is disposed in the first and second shielding parts. This nested arrangement allows openings at different levels to be positioned without compromising each other's shielding effectiveness.
2Reliability
If multiple shielding parts are coupled together, then electromagnetic shielding performance is improved, but device complexity increases
Solution Approach 1:
The first shielding part and second shielding part are coupled together to form an integrated multi-layer shielding structure. The grounding part, first shielding part, second shielding part, and plastic core are combined in a nested configuration, merging multiple shielding functions into a unified assembly that enhances electromagnetic shielding performance while managing complexity through integrated design.
