Wire-Bending Connector Housing for Stable Miniaturized Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Miniaturization of connectors for vehicles leads to reduced strength of locking components, causing terminals to rattle due to external forces transmitted through wires, and potentially damaging the terminals themselves.
Innovation Solution
A connector design featuring a lower housing and upper cover with guide portions that bend wires upon assembly, absorbing external forces and reducing transmission to terminals, while allowing for efficient manufacturing through rotatable and movable parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the connector size is reduced for miniaturization, then the connector can be equipped in vehicles with space constraints, but the strength of locking components is reduced causing terminals to rattle due to external forces
Solution Approach 1:
The guide portions are designed to bend the wires before the terminals are fully inserted into the housing. This preliminary bending action pre-absorbs external forces, so when the terminals are locked in place, the forces have already been mitigated, preventing rattling and damage to the miniaturized locking components
Solution Approach 2:
The guide portions act as intermediary elements between the wires and the terminals. By introducing these guide portions that bend the wires, external forces are absorbed and redirected before reaching the terminals and the weakened locking components, effectively mediating the force transmission path
2Volume of moving object
If the terminal size is reduced for miniaturization, then the connector can be equipped in vehicles with space constraints, but the strength of terminals themselves is reduced making them vulnerable to damage from external forces
Solution Approach 1:
The guide portions bend the wires before the external forces are transmitted to the terminals. This preliminary action of bending the wires absorbs and redirects forces, protecting the miniaturized terminals from damage before the forces can affect them
Solution Approach 2:
The guide portions serve as intermediary elements that intercept external forces applied to the wires. By bending the wires within the guide portions, the forces are absorbed and redirected away from the vulnerable miniaturized terminals, protecting them from damage
