Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The conventional fabrication of female connectors for high-speed transmission is complex due to the need for different types of insulating bodies and terminal groups, increasing fabrication difficulty as applications diversify.
Innovation Solution
A female connector design with an insulating body divided into upper, middle, and lower parts, allowing direct mounting of terminal groups and engagement via shielding cases to form an integrated connector body, which can accommodate various terminals and improve high-frequency performance with metal sheets and spring plates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different types of insulating bodies are fabricated to accommodate various terminal types, then the connector can receive diversified terminals, but the fabrication difficulty level increases greatly
Solution Approach 1:
The insulating body is designed with a universal structure that can accommodate multiple types of terminals (high-frequency, low-frequency, grounding terminals) through standardized mounting positions and engagement features. The upper and lower insulating bodies are configured with corresponding structures that allow different terminal groups to be mounted using the same fabrication process, eliminating the need for different insulating body types for different terminal applications.
2Device complexity
If the insulating body is integrally formed, then the structure is simple, but it cannot easily adapt to different terminal types
Solution Approach 1:
The insulating body is divided into an upper insulating body and a lower insulating body, which are engaged together to form the complete insulating structure. This segmentation allows each part to be optimized for specific functions while maintaining overall structural simplicity. The division enables flexible configuration of terminal groups by allowing different terminal types to be mounted on respective insulating bodies using standardized engagement features.
3Reliability
If the contact portion thickness of high frequency terminal pair is reduced, then high frequency performance is improved, but the structural strength may be compromised
Solution Approach 1:
The high frequency terminal pair features a locally optimized contact portion with reduced thickness specifically at the contact area to improve high frequency signal transmission by minimizing signal loss and interference. The reduced thickness is localized only where needed for electrical contact, while the overall terminal structure maintains adequate strength through its complete geometry and engagement features with the insulating body.
