Connector Ferrite Housing Segmentation Vibration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional connectors using ferrites for noise reduction face issues with ferrite contact due to vibration, as they are held by biasing arms which can cause changes in ferrite properties and mutual contact between adjacent ferrites.
Innovation Solution
The connector design incorporates ferrites with rounded corner portions and a housing featuring accommodating portions with projections on facing wall portions, allowing ferrites to be individually accommodated without biasing arms, thus preventing escape and minimizing property changes, while also reducing the connector's size and weight by partitioning adjacent ferrites with intermediate walls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If ferrites are held by biasing arms in the housing, then the ferrites can be secured in position, but the ferrites may contact each other due to vibration and their properties may change
Solution Approach 1:
The housing is divided into multiple accommodating portions, each independently holding a ferrite. The accommodating portions are separated by intermediate walls, creating isolated spaces for each ferrite. This segmentation prevents ferrites from contacting each other while maintaining individual positioning stability without requiring biasing arms that could cause property changes.
2Object-affected harmful factors
If intermediate walls are disposed between adjacent accommodating portions, then ferrite mutual contact is prevented, but the connector size and complexity increase
Solution Approach 1:
The intermediate walls are integrated directly into the housing structure as a unified component rather than separate elements. The housing forms a single molded piece where the intermediate walls are built-in features that naturally separate the accommodating portions. This merging approach prevents ferrite contact while avoiding additional assembly steps or separate components, thus not increasing overall device complexity.
