Electrical Connector Terminal Structure for Heat and Shielding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connector sets do not adequately address the improvement of electrical characteristics, particularly in terms of heat generation due to overcurrent and shielding properties.
Innovation Solution
The electrical connector set includes a first substrate with a first conductor and a first internal terminal having two mounting portions and a projecting portion, and a second substrate with a second conductor and a second internal terminal with a recessed portion, allowing for the dispersion of electricity and improved fitting and contact pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single mounting portion is used for internal terminals, then the device complexity is reduced, but the electrical characteristics deteriorate due to concentrated current causing heat generation
Solution Approach 1:
The internal terminals are divided into multiple mounting portions (first mounting portion and second mounting portion) instead of using a single mounting portion. This segmentation disperses the concentrated current across multiple contact points with the circuit board, reducing heat generation at any single point while maintaining structural feasibility
Solution Approach 2:
Different portions of the internal terminals are given different functions: the first and second mounting portions are optimized for electrical contact with the circuit board, while the projecting portion is optimized for connection with the connector housing. This local differentiation allows each portion to be optimized for its specific function, improving overall electrical characteristics
2Ease of manufacture
If internal terminals are simply mounted on substrates, then the ease of manufacture is improved, but the shielding properties deteriorate due to insufficient current dispersion
Solution Approach 1:
The internal terminals incorporate multiple mounting portions that segment the current path, improving shielding properties by dispersing electromagnetic interference and reducing concentrated current effects, while still maintaining relatively simple assembly procedures
Solution Approach 2:
The internal terminals extend in multiple dimensions with mounting portions at different locations and a projecting portion extending toward the connector housing. This multi-dimensional configuration improves shielding properties by creating distributed current paths in three-dimensional space, while the overall structure remains manufacturable
3Reliability
If the internal terminals have extended projecting portions, then the electrical characteristics are improved through better contact, but the device complexity increases due to additional structural elements
Solution Approach 1:
The internal terminal integrates multiple functions into a single component: electrical connection to the circuit board through mounting portions, mechanical support through the body portion, and connection to the connector housing through the projecting portion. This merging reduces overall device complexity compared to using separate components for each function while maintaining reliable electrical characteristics

AI summary
An electrical connector set includes a first substrate having a first conductor, and a first internal terminal having a first mounting portion and a second mounting portion that are mounted on the first conductor of the first substrate and a projecting portion extending in a curved shape between the first mounting portion and the second mounting portion. The electrical connector set further includes a second substrate having a second conductor, and a second internal terminal having a third mounting portion that is mounted on the second conductor of the second substrate and a recessed portion forming the third mounting portion at a bottom portion, in which the projecting portion of the first internal terminal and the recessed portion of the second internal terminal are configured to be fitted to each other.
