Plug Connector Spring Contact Portions Current Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electrical connectors face challenges in miniaturization while maintaining effective power supply current distribution, leading to heat generation issues due to concentrated current paths.
Innovation Solution
The design incorporates a pair of integrally formed spring contact portions with a bent-plate shape, arranged symmetrically to face each other, with offset mounting portions and a connecting plate-like structure, allowing for efficient power supply current division and reduced heat generation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single contact portion is used for power supply, then the structure is simple, but the power supply current is concentrated causing heat generation
Solution Approach 1:
The power supply contact is divided into multiple contact portions (first and second contact portions) instead of using a single contact portion. This segmentation distributes the power supply current across multiple paths, reducing current concentration and preventing heat generation while maintaining structural simplicity
2Temperature
If the size of power supply contacts is increased to prevent heat generation, then heat generation is reduced, but miniaturization cannot be achieved
Solution Approach 1:
Instead of increasing the size of individual contacts, the invention segments the contact into multiple smaller portions. This allows the connector to maintain a compact size while distributing current across multiple contact points, preventing heat generation without sacrificing miniaturization
3Temperature
If three contact portions are provided to divide power supply current, then current division is achieved, but uneven shape causes current concentration on larger contact portion
Solution Approach 1:
The invention uses two contact portions of equal size and shape (symmetrical design) rather than uneven configurations. This symmetrical arrangement ensures balanced current distribution across both contact portions, preventing current concentration on any single portion and effectively preventing heat generation
