Male Ground Terminal Resonance Path for Connector Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors face challenges in achieving sufficient isolation characteristics without increasing the connector size, particularly when adjacent signal terminals are spaced farther apart or when using U-shaped ground terminals with cavity areas.
Innovation Solution
The electrical connector design incorporates a male ground terminal with a first and second lengthwise extending part, a laterally connecting part, and a connection path forming a resonance path, which enhances isolation characteristics without increasing the connector's size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the distance between adjacent signal terminals is increased to prevent signal interference, then isolation characteristics are improved, but the connector size increases
Solution Approach 1:
A ground terminal is introduced as an intermediary element disposed between adjacent signal terminals. This ground terminal acts as a mediator to provide electromagnetic shielding and prevent signal interference, allowing the signal terminals to maintain smaller spacing while achieving sufficient isolation characteristics without increasing connector size.
Solution Approach 2:
The ground terminal is designed with specific structural parameters including a resonance path formed by the connection path, first lengthwise extending part, second lengthwise extending part, and laterally connecting part. By optimizing these parameters, the ground terminal achieves effective signal isolation at high frequencies while maintaining compact dimensions.
2Ease of manufacture
If a U-shaped ground terminal with cavity area is used, then ease of manufacture is improved, but isolation characteristics are insufficient
Solution Approach 1:
The ground terminal is segmented into distinct functional parts: first lengthwise extending part, second lengthwise extending part, laterally connecting part, and connection path. This segmentation allows each part to contribute specifically to forming the resonance path, achieving effective isolation characteristics while maintaining manufacturability through modular design.
Solution Approach 2:
The ground terminal incorporates a resonance path that utilizes electromagnetic resonance to enhance isolation characteristics. The connection path and extending parts are dimensioned to create resonant structures that effectively suppress signal interference at specific frequency ranges, transforming the ground terminal from a simple shielding element to an active isolation mechanism.
