Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
External vibrations can cause floating of the mating terminal relative to the electrical connector, leading to failed electrical connections and potential damage to the terminal or connector.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a rigid terminal structure is used, then manufacturing precision is improved, but reliability deteriorates due to inability to accommodate vibrations
Solution Approach 1:
The terminal is designed with elastic properties, transforming it from a rigid static structure to a dynamic component that can adapt to vibrations and positional variations, thereby maintaining reliable electrical connection without compromising manufacturing precision
Solution Approach 2:
The terminal material or structure is modified to introduce elasticity, changing the physical parameter of rigidity to allow controlled deformation that absorbs vibration energy while maintaining precise electrical contact
2Device complexity
If a fixed mounting structure is used, then device complexity is reduced, but reliability deteriorates due to floating caused by vibrations
Solution Approach 1:
The mounting structure incorporates elastic elements that allow controlled movement and absorption of vibration energy, transforming a static fixed structure into a dynamic system that maintains stable electrical connection while remaining relatively simple in design
3Reliability
If an elastic terminal is used, then reliability is improved by accommodating vibrations, but device complexity increases due to additional elastic mechanism
Solution Approach 1:
The elastic function is integrated directly into the terminal structure itself rather than being added as a separate mechanism, merging the electrical contact function with the vibration absorption function into a single unified component, thereby improving reliability without proportionally increasing device complexity

AI summary
An electrical connector adapted to be electrically connected with a mating terminal includes an outer housing, an inner housing, and an elastic terminal. The outer housing includes an outer cylindrical body, and an upper blocking disc and a lower blocking disc radially extending inwardly from opposite ends of the outer cylindrical body, the upper blocking disc has an outer through hole. The inner housing includes an inner cylindrical body and a mounting portion surrounding an outer periphery of the inner cylindrical body. The inner housing is formed with an inner through hole. The mounting portion is movably mounted in a space defined by the outer cylindrical body, the upper blocking disc, and the lower blocking disc. The elastic terminal is mounted within the inner cylindrical body and adapted to be electrically connected with the mating terminal inserted into the inner cylindrical body through the outer through hole and the inner through hole.
