Connector Releasing Portion Arch Bridge Rigidity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connectors face challenges in ensuring the strength of the releasing portion when mounted on a panel, particularly due to the difficulty in maintaining the strength of the temporary holding releasing plate during deformation.
Innovation Solution
A connector design featuring a first housing with a resiliently deformable lock arm and a second housing with a space portion, leg portions, and a bridge portion that forms an arch structure, enhancing the rigidity of the releasing portion and allowing for miniaturization by overlapping the outer wall and receptacle in the front-rear direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the outer wall of the insertion path and receptacle are positioned to overlap in the front-rear direction for miniaturization, then the front-rear length of the connector is reduced, but the strength of the temporary holding releasing plate cannot be ensured due to deflection and deformation
Solution Approach 1:
The releasing portion is divided into multiple segments: the temporary holding releasing plate is separated from the outer wall structure, and the bridge portion is divided into leg portions and a connecting web. This segmentation allows each part to be optimized independently - the releasing plate can be made thin for miniaturization while the bridge portion provides structural support through its geometric configuration.
Solution Approach 2:
The bridge portion is designed with an arch-shaped curved structure connecting the leg portions. This curvature provides structural rigidity and resistance to deflection forces, allowing the releasing portion to maintain strength despite the overlapping positioning that enables miniaturization. The arch shape efficiently distributes mechanical loads.
2Device complexity
If the temporary holding releasing plate is provided on the outer wall of the insertion path for releasing the lock, then the connector structure is simplified, but the outer wall may be deflected and deformed making it difficult to ensure the strength of the releasing portion
Solution Approach 1:
The releasing portion is segmented into the temporary holding releasing plate and the bridge portion with leg portions. This allows the releasing plate to be thin and simple while the bridge portion provides the necessary structural strength through its geometric configuration, resolving the contradiction between structural simplicity and strength.
Solution Approach 2:
Different parts of the releasing portion have different thicknesses and structural properties. The temporary holding releasing plate is thin for simplicity, while the bridge portion has a thicker, arch-shaped configuration for strength. This local differentiation allows each part to optimize its function without compromising the other.
