Connector Module Shielding Springs for Flexible Earthing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing plug connector modular systems face challenges with complex assembly and replacement of modules, insufficient electrical shielding, and the inability to retrofit shielding connections, leading to interference issues with high-frequency signals and difficulties in adapting to changing earthing concepts in complex electrical systems.
Innovation Solution
A plug connector module with a cuboid insulating member and integrated contact springs that can be locked onto the module, allowing for flexible earthing and easy connection or disconnection from the plug connector modular frame, enabling selective earth connection and shielding without disassembling the elementary connectors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If plug connector modules are inserted into a modular frame with retention means and through-openings, then the modules can be securely retained and replaced, but the assembly and replacement process becomes complex requiring disassembly of the entire frame
Solution Approach 1:
The modular frame is divided into multiple individual retention positions, each with its own independent retention means (clamps or springs). This allows individual modules to be accessed and replaced without affecting other modules, eliminating the need to disassemble the entire frame structure.
Solution Approach 2:
The retention means are designed as dynamic elements (movable clamps or springs) that can be independently actuated at each retention position. This enables selective opening and closing of retention means for individual modules, providing flexible access while maintaining secure retention for all modules.
2Strength
If a metal modular frame is used for structural strength and grounding, then mechanical stability is improved, but electrical shielding of individual modules cannot be selectively configured
Solution Approach 1:
The shielding capability is segmented and assigned to individual modules through integrated shielding elements or contact springs, rather than requiring a fully enclosed metal frame. This allows selective shielding configuration for each module based on its specific electrical requirements.
Solution Approach 2:
Different modules can have different shielding configurations tailored to their specific needs. High-frequency signal modules can be equipped with shielding elements and contact springs for electromagnetic shielding, while other modules can operate without such shielding, optimizing both electrical performance and cost.
3Reliability
If existing modules are replaced in a secured modular frame, then system reliability is maintained, but all modules must be removed and reinstalled even if only one needs replacement
Solution Approach 1:
The retention system is segmented into independent retention means for each module position. This allows the targeted module to be released and replaced by actuating only its specific retention means, while other modules remain securely retained without requiring removal or reinstallation.
Solution Approach 2:
The dynamic retention means can be independently actuated to release or secure individual modules. This enables rapid replacement of single modules by simply opening the relevant clamp or spring, replacing the module, and closing the retention means, significantly reducing replacement time.

AI summary
In order to be able to modify earthing concepts as quickly, flexibly and easily as possible, the earth connection of the shielding housings (20, 20′) of a connector module is produced by contact springs (3) that can be clipped onto and removed from the short side of the module's insulating body (1, 1′) from the exterior.
