Connector Structure Metal Plate Spring Vibration Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connector structures face issues with reduced elastic repulsive force over time due to the use of resin-based packing, leading to reduced vibration resistance and potential electrical connection reliability, especially under vehicle vibrations.
Innovation Solution
A connector structure incorporating a metal plate spring member and a playing regulating member with inclined surfaces, which compresses and deforms to maintain a stable elastic repulsive force, eliminating clearance in the lock mechanism and preventing rattling, even after aging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a resin-based packing is used to prevent rattling, then the initial vibration resistance is improved, but the elastic repulsive force is reduced due to deterioration over long-term use, leading to reduced electrical connection reliability
Solution Approach 1:
The patent changes the material parameter from resin-based packing to a metal plate spring member. This material substitution fundamentally alters the elastic properties, providing superior long-term durability while maintaining the necessary elastic repulsive force for preventing rattling and ensuring electrical connection reliability.
Solution Approach 2:
The invention uses a composite structure combining the metal plate spring member with the housing and terminal components. The metal plate spring member works in conjunction with the housing structure to provide both mechanical support and elastic functionality, achieving both initial vibration resistance and long-term durability.
2Reliability
If the plate spring member is compressed to eliminate clearance in the lock mechanism, then the vibration resistance is improved by preventing rattling, but the insertion force required increases
Solution Approach 1:
The plate spring member is designed to provide partial compression that eliminates clearance in the lock mechanism without requiring excessive insertion force. The elastic deformation is controlled to achieve the minimum necessary compression for preventing rattling while keeping the insertion force within acceptable limits.
Solution Approach 2:
The plate spring member provides dynamic elastic deformation during insertion and maintains a controlled compressed state during operation. This dynamic behavior allows the system to adapt to the insertion process, reducing the peak insertion force required while still achieving the necessary clearance elimination for vibration resistance.
