Electrical Connector EMI Shielding via Elastic Member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors face challenges in effectively shielding electromagnetic interference (EMI) due to the limited coverage of shielding members, which can lead to EMI leakage, especially when external devices are moved or connected.
Innovation Solution
An electrical connector design featuring a conductive elastic shielding member that contacts both the inner surface of the male connector and the outer surface of the female connector, providing EMI shielding at two points by forming an 'L' shape with inclined surfaces, and being seated in a groove on the female connector, enhancing adhesion and shielding performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a shielding member is disposed at a gap between the female connector and the male connector, then EMI shielding is provided at that location, but EMI leakage occurs in other directions due to limited coverage
Solution Approach 1:
The shielding member is configured to contact both the inner surface of the male connector and the outer surface of the female connector simultaneously, extending the shielding coverage from a single point to multiple dimensions. The first surface contacts the inner surface of the male portion while the second surface contacts the outer surface of the female portion, creating multi-directional EMI shielding coverage
Solution Approach 2:
The shielding member is divided into multiple functional surfaces: a first surface for contacting the inner surface of the male portion, a second surface for contacting the outer surface of the female portion, and an inclined surface connecting them. This segmentation allows each surface to address EMI shielding in different directions and locations
2Stability of the object's composition
If the shielding member is made rigid for stable contact, then contact stability is improved, but adaptability to connector movement and connection state changes deteriorates
Solution Approach 1:
The shielding member is made of an elastic material, changing the physical parameter of rigidity to flexibility. This allows the shielding member to deform and adapt to different connection states and movements while maintaining stable contact with both the male and female connectors throughout the coupling process
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design effectively shields EMI at two points in different directions, improving the overall shielding performance and preventing leakage, even during device movement or connection changes.
Implementation Method 1
a portion of the shielding member is disposed between the inner surface of the male portion and an outer surface of the female portion so as to be in contact with the inner surface of the male portion and the outer surface of the female portion
Implementation Method 2
the shielding member is formed of a conductive elastic body
