Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors with ground members struggle to maintain stable electrical communication due to potential gaps between ground plates and ground terminals caused by fabrication errors or distortion, leading to instability in electrical coupling.
Innovation Solution
The electrical connector features a retaining member with perforation portions between signal transmission paths, and a shorting member of electrically conductive plastics co-molded with ground members, ensuring stable electrical communication by shorting the ground members through the coupling portions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If ground plates are placed in gapless surface contact with ground terminals to ensure stable electrical communication, then electrical coupling balance is improved, but the configuration becomes sensitive to fabrication errors and distortion causing gaps
Solution Approach 1:
The ground plate contact surface is divided into multiple protrusions that engage with corresponding recesses in the ground terminal. This segmentation allows each protrusion-recess pair to independently maintain contact, reducing the impact of fabrication errors on overall electrical communication stability.
Solution Approach 2:
The invention changes the contact interface geometry from flat surface contact to protrusion-recess engagement. This parameter change in the contact surface topology enables tolerance compensation, where the protrusions can align with recesses even when fabrication variations exist, maintaining reliable electrical coupling.
2Object-affected harmful factors
If ground plates are bent to contact ground terminals to shield signal terminals, then crosstalk prevention is improved, but stable electrical communication between ground members becomes difficult to ensure
Solution Approach 1:
The ground plate is segmented into multiple protrusions that independently contact the ground terminal. This segmentation allows the ground plate to maintain shielding function while ensuring stable electrical communication through the protrusion-recess engagement mechanism.
Solution Approach 2:
The protrusions act as intermediaries between the ground plate and ground terminal, providing a reliable contact interface that ensures stable electrical communication while maintaining the shielding configuration for crosstalk prevention.
