Electrical Connector Shielding Orientation via Coding Means
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electrical plug-and-socket connectors in the automotive sector face durability issues due to folds in electromagnetic shielding, which interfere with mating connectors and lead to damage, and existing shieldings struggle with robust and permanent seating.
Innovation Solution
The use of coding means such as ribs and slots on the plug-and-socket connector body and shielding ensures correct orientation and positioning of the shielding, preventing electrical contact with folds and providing robust fastening, thus enhancing durability and preventing damage to contact arms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If resilient electrical contact arms are used to contact the shielding, then electrical contact is achieved, but the folds in the shielding cause damage to the contact arms and reduce durability
Solution Approach 1:
The shielding is pre-formed with coding means (protrusions and recesses) that guide its positioning before contact occurs. The fold is strategically positioned away from contact zones during assembly, preventing damage to contact arms while maintaining electrical connectivity.
Solution Approach 2:
The coding means act as an intermediary mechanism between the shielding and the connector body. The protrusions and recesses mediate the positioning process, ensuring the shielding settles in the correct orientation where folds do not interfere with contact arms.
2Object-affected harmful factors
If electromagnetic shielding is added to protect against spurious signals, then electromagnetic compatibility is improved, but the shielding creates folds that interfere with mating connectors
Solution Approach 1:
The shielding is segmented into functional zones: contact zones with coding means for positioning, and non-contact zones where folds are permitted for electromagnetic shielding effectiveness. This segmentation allows both protection and compatibility.
Solution Approach 2:
Different regions of the shielding have different properties: areas contacting the connector body have precise geometric coding means, while other areas accommodate folds for electromagnetic shielding. Each region is optimized for its specific function.
3Manufacturing precision
If coding means are added to position the shielding correctly, then positioning precision is improved, but the device complexity increases
Solution Approach 1:
The coding means are merged with the shielding structure itself rather than being separate components. The protrusions and recesses are integrated into the shielding, achieving precise positioning without adding external complexity.
Solution Approach 2:
The coding means serve multiple functions: they provide positioning guidance, ensure correct orientation, prevent misalignment, and facilitate assembly. This multi-functionality reduces the need for separate positioning mechanisms.
