Liquid-Cooled Electrical Connector Terminal Structure for Signal Integrity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electrical connectors face challenges in maintaining signal integrity and preventing damage to conductive terminals in liquid-cooled environments, where the elastic arms need to be shortened to avoid improper abutment by the mating connector.
Innovation Solution
The electrical connector features a conductive terminal with an end portion bent from the contact portion, spaced apart from the bottom surface, and an end surface located outside the inner wall surface, along with a cooling liquid circulation groove and slot for heat dissipation, ensuring the end portion is not damaged by the mating connector while maintaining signal integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the elastic arm is lengthened to avoid improper abutment of the mating connector, then the reliability of the conductive terminal is improved, but the signal transmission integrity deteriorates in liquid-cooled environments
Solution Approach 1:
The end portion of the elastic contact arm is bent from the contact portion at a specific angle, transitioning from a linear configuration to a three-dimensional configuration. This dimensional change allows the end portion to be positioned away from the bottom surface of the insulating body, preventing improper abutment while maintaining a compact overall length that preserves signal integrity in liquid-cooled environments.
2Loss of information
If the elastic arm is shortened to improve signal transmission integrity, then the signal transmission integrity is improved, but the reliability of the conductive terminal deteriorates due to improper abutment
Solution Approach 1:
Instead of simply shortening the elastic arm, the invention bends the end portion from the contact portion to reposition it in three-dimensional space. This allows the elastic arm to be effectively shortened for signal integrity while the bent configuration prevents the end portion from contacting the bottom surface, avoiding improper abutment and maintaining reliability.
3Device complexity
If the end portion is positioned inside the inner wall surface for structural compactness, then the device complexity is reduced, but the end portion becomes vulnerable to damage from the mating connector
Solution Approach 1:
The end portion is bent from the contact portion and positioned to extend beyond the inner wall surface of the insulating body. This three-dimensional positioning protects the end portion from damage by the mating connector while maintaining a compact overall structure, as the bent configuration utilizes space more efficiently than a linear extension.
