Connector Housing Structure for Pin Terminal Rebound Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pin terminals in electrical connectors experience positional instability due to rebounding of bent portions after removal from bending jigs, leading to tolerance issues.
Innovation Solution
A connector housing with accommodating channels and blocking structures that prevent the bent portion of pin terminals from rebounding, using protrusions and buffer openings to securely hold the bent portions in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If pin terminals are bent using a bending jig, then the pin terminal shape is formed, but the bent portion rebounds after jig removal causing position instability
Solution Approach 1:
The blocking structure is designed to apply preliminary counter-action to the rebound force of the bent portion. The protrusion extends into the accommodating channel to block the rebound movement, and the buffer opening provides controlled deformation space to absorb residual stress, preventing position drift after bending.
Solution Approach 2:
The blocking structure acts as an intermediary element between the bent portion and the accommodating channel. It mediates the interaction by providing a blocking surface that limits rebound while allowing controlled deformation through the buffer opening, ensuring stable positioning without direct rigid constraint.
2Stability of the object's composition
If blocking structures are added to prevent rebound, then position stability is improved, but device complexity increases
Solution Approach 1:
The blocking structure is merged with the accommodating channel as an integrated feature of the connector housing. The protrusion and buffer opening are formed as part of the housing structure rather than separate components, reducing assembly steps and overall device complexity while maintaining the rebound prevention function.
Solution Approach 2:
The blocking structure serves multiple functions: it blocks rebound movement, provides controlled deformation space through the buffer opening, and maintains positioning stability. This multi-functionality reduces the need for additional separate components, simplifying the overall device structure.
