Terminal Assembly Plug End Segmentation for Signal Integrity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The SI performance of conventional connectors is affected by the length of the plug end part, which impacts the characteristic impedance, insertion loss, return loss, near-end crosstalk, and far-end crosstalk.
Innovation Solution
A terminal assembly with a first terminal component and a second terminal component, where the first plug end part and second plug end part are shortened, and extension protectors are used as insulators to prevent deformation and enhance structural strength, while maintaining SI performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the plug end part length is increased, then the structural strength is improved, but the SI performance deteriorates
Solution Approach 1:
The plug end part is segmented into two functional zones: a shortened metal conductor portion (plug elastic sheet) for optimal SI performance, and an extended insulator portion (extension protector) for enhanced structural strength and protection. This segmentation allows each material to fulfill its optimal function without compromising the other.
Solution Approach 2:
The plug end part uses a composite structure combining metal conductor material (for electrical connectivity) and insulator material (for protection and structural support). The extension protector made of insulator material complements the metal plug elastic sheet, creating a composite component that simultaneously achieves electrical performance and mechanical strength.
2Reliability
If the plug end part length is shortened, then the SI performance is improved, but the structural strength deteriorates
Solution Approach 1:
The protective function is segmented from the metal conductor and assigned to the extension protector (insulator portion). This allows the metal plug end to be shortened for better SI performance while the insulator extension compensates for the lost structural strength and provides continued protection.
Solution Approach 2:
The extension protector acts as an intermediary element that provides structural support and protection to the shortened plug end part. It mediates between the need for short length (for SI performance) and the need for structural strength, allowing the metal conductor to be short while maintaining overall component strength through the insulator extension.
