Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connection systems face challenges in maintaining a continuous electrical connection between the metallic shield and a flexible conductive sheet, particularly when the shield has a polygonal cross-section, which is prone to electromagnetic interference.
Innovation Solution
An electrical connection system comprising a metallic shield with a polygonal cross-section, a flexible electrically conductive sheet, and an attachment system with rigid arms and adjustment mechanisms that adapt radially to fit tightly around the shield, ensuring a secure and uniform contact between the sheet and the shield.

1Object-affected harmful factors
If a flexible conductive sheet is used to surround the metallic shield, then electromagnetic interference protection is improved, but maintaining continuous electrical connection becomes difficult when the shield has a polygonal cross-section
Solution Approach 1:
The attachment system incorporates adjustment mechanisms that allow the rigid arms to move dynamically during assembly, adapting to the polygonal cross-section of the shield. This dynamic adjustment enables the system to achieve and maintain continuous electrical connection between the flexible sheet and the shield despite the non-circular geometry
Solution Approach 2:
The rigid arms with adjustment mechanisms serve as an intermediary between the flexible conductive sheet and the metallic shield. This intermediary component facilitates the establishment of continuous electrical connection by bridging the gap caused by the polygonal cross-section, allowing the flexible sheet to maintain reliable contact with the shield
2Reliability
If rigid arms with adjustment mechanisms are used to attach the flexible sheet to the polygonal shield, then electrical connection reliability is improved, but device complexity increases
Solution Approach 1:
The attachment system is segmented into multiple rigid arms that can be independently adjusted and assembled. This segmentation allows for simpler individual components that can be manufactured and assembled separately, reducing overall complexity while maintaining reliability through the collective action of multiple arms
Solution Approach 2:
The adjustment mechanisms provide controlled flexibility to the otherwise rigid structure. By introducing only the necessary degrees of freedom for adaptation to polygonal cross-sections, the system achieves reliability without excessive complexity - the mechanisms allow movement during assembly but maintain a stable, rigid connection during operation

AI summary
The electrical connector comprises a metallic shield (7) having a rear portion with a polygonal cross- section. The flexible sheet (13) has a flexible electrically conductive front section which surrounds the rear portion of the metallic shield. The attachment system surrounds the front section of the flexible sheet (13), and has rigid arms (16a, 16b) interconnected to correspond to the polygonal cross- section, and adjustment mechanisms adapted to guide adjacent rigid arms along a radial degree of freedom.
