Power Connector Fuse Position Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power connectors with built-in fuses lack a stable mechanism for maintaining the fuse position, which can lead to instability and potential failure in preventing overcurrents.
Innovation Solution
A power connector design featuring a main housing, internal body, and cover housing with clips and guide portions that securely accommodate and support cylindrical fuses, using elastically deformable terminals and a sealing member to ensure stable fuse placement and prevent moisture ingress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If a fuse is detachably mounted to the connector, then the fuse can be replaced after blowing, but the fuse position becomes unstable and may lead to failure in preventing overcurrents
Solution Approach 1:
The connector is divided into multiple functional parts: a housing, a removable fuse holder, and retaining structures. The fuse holder can be detached from the housing to replace the fuse, while the retaining structures ensure stable positioning during operation. This segmentation allows both ease of repair and operational reliability.
Solution Approach 2:
The fuse is pre-installed in the fuse holder with retaining structures that secure it in place before operation. The retaining structures are designed to automatically engage and hold the fuse securely, preventing position instability during use. This preliminary securing action ensures reliability while maintaining replaceability.
2Adaptability or versatility
If the connector includes multiple terminals and clips for power distribution, then power can be distributed to multiple devices, but the structure becomes more complex
Solution Approach 1:
The connector design uses universal clip structures and terminal configurations that can accommodate multiple fuses and distribute power to multiple devices. The clips and retaining structures serve dual purposes: securing fuses in place and providing structural support for power distribution. This multi-functionality increases versatility without proportionally increasing complexity.
Solution Approach 2:
The connector employs a nested structure where the fuse holder is contained within the housing, and multiple terminals are integrated into the same structural framework. The retaining structures are embedded within the housing to secure the fuse holder. This nesting approach allows multiple functions (power distribution, fuse mounting, retention) to coexist in a compact arrangement, managing complexity efficiently.
