Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors with grounding structures are complicated to install and can affect the shielding effect due to improper overlap.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a grounding structure with multiple grounding terminals and shielding sheets is used, then the shielding effect is improved, but the installation complexity increases
Solution Approach 1:
The patent combines multiple grounding terminals into a single integrated grounding terminal structure that spans across the insulating housing. This single grounding terminal incorporates multiple contact points and integrates the functions of what would otherwise require multiple separate terminals and shielding sheets, thereby maintaining the shielding effect while significantly simplifying the installation process
Solution Approach 2:
The grounding terminal is designed with multi-functional capabilities: it provides grounding contact through its body, establishes electrical connection via the grounding pin, and maintains structural stability through the clamping structure. This universal design allows a single component to perform multiple functions that would traditionally require separate components, reducing installation complexity while preserving shielding effectiveness
2Object-affected harmful factors
If a grounding structure with overlapping shielding sheets is used, then the shielding effect is improved, but the installation precision requirement increases
Solution Approach 1:
The patent extracts the complex overlapping shielding sheet structure and replaces it with a simplified grounding terminal design. The grounding terminal directly contacts the insulating housing and establishes grounding connections without requiring multiple layers of shielding sheets to be precisely overlapped and positioned, thereby eliminating the high precision overlap requirement while maintaining shielding effectiveness
Solution Approach 2:
Instead of using multiple shielding sheets that require precise overlap from the outside in, the invention inverts the approach by using a single grounding terminal that establishes grounding from the inside out. The grounding terminal's clamping structure secures it firmly to the insulating housing, ensuring stable electrical contact without requiring external shielding sheets to be precisely aligned

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The improved grounding structure enhances the shielding effect and simplifies the installation process by using elastic arms and support platforms to secure the terminals effectively.
Implementation Method 1
an upper elastic arm extending upwardly from the transverse portion and then bending above the body portion, a lower elastic arm extending downwardly from the transverse portion and then bending below the body portion
