Multi-Directional HV Junction Box Connector for Flexible Battery I/O
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current high-voltage electronic boxes have non-configurable battery input/output, limiting their applications due to a fixed orientation of the battery cable, which restricts the versatility and adaptability of the HV electronic box in various applications.
Innovation Solution
A multi-directional connector assembly that allows for configurable connections between a high-voltage electronic box and a battery, enabling multiple orientations and configurations by using bus bars and leads that can be connected in various configurations within the HV electronic box, allowing for flexible positioning of terminals and leads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed orientation battery cable connection is used in high-voltage electronic boxes, then the structural simplicity is maintained, but the adaptability and versatility are limited
Solution Approach 1:
The connector assembly is designed with multiple bus bars (first and second positive bus bars, first and second negative bus bars) that can be configured in different orientations, allowing a single connector type to serve multiple connection directions and applications, thereby achieving universality without requiring separate connectors for each orientation
2Adaptability or versatility
If multiple bus bars and leads are used to enable multi-directional connections, then the configurability is improved, but the device complexity increases
Solution Approach 1:
Multiple bus bars and leads are integrated into a single connector assembly that is housed together with the electronic box, merging what would otherwise be separate components into one unified structure, thereby reducing the number of discrete parts and simplifying installation while maintaining multi-directional connectivity
