Electrical Connector Elastic Arms Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors with C-shaped conductive terminals require high strength for stable connection due to low elasticity, making them difficult to mate with chip modules effectively.
Innovation Solution
The design incorporates two separate elastic arms at each conductive terminal with bending and widening portions to increase elasticity and prevent fatigue, allowing for easier pressing and improved high-frequency transmission performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a C-shaped base is used for the conductive terminal, then the structural strength is improved, but the elasticity deteriorates
Solution Approach 1:
The conductive terminal is divided into separate components: an insulating base and multiple independent elastic arms. This segmentation allows each elastic arm to independently provide elasticity while the insulating base provides structural support, resolving the contradiction between strength and elasticity.
Solution Approach 2:
The conductive terminal uses composite structure combining insulating material (base) and conductive elastic material (arms). This composite design allows the insulating base to provide structural strength while the conductive elastic arms provide the necessary elasticity and electrical conductivity.
2Strength
If the C-shaped base is made thicker to increase strength, then the structural strength is improved, but the elasticity deteriorates
Solution Approach 1:
By separating the structural support function (insulating base) from the elastic deformation function (elastic arms), the design allows thin elastic arms that are easy to press while the insulating base provides the necessary structural strength.
Solution Approach 2:
The insulating base is designed with localized reinforcing ribs or thickened portions at critical stress points, providing structural strength only where needed, while allowing the elastic arms to remain thin and highly elastic for ease of pressing.
3Reliability
If greater strength is applied to maintain stable connection, then the connection stability is improved, but the ease of operation deteriorates
Solution Approach 1:
The separation of insulating base and elastic arms allows the elastic arms to provide stable electrical connection through their elastic recovery force, while the insulating base provides mechanical support, reducing the overall force needed for mating.
Solution Approach 2:
The elastic arms are designed with optimized thickness and material properties to provide sufficient elastic recovery force for stable connection while maintaining low insertion force, achieving both connection stability and ease of operation through parameter optimization.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The enhanced elasticity facilitates easier pressing of the chip module, reduces fatigue, and improves impedance and compatibility for better high-frequency transmission performance.
Implementation Method 1
the elastic portion has a first elastic arm and a second elastic arm... the first elastic arm has a first bending portion bending toward one side thereof... the second elastic arm has a second bending portion bending toward one side thereof... elastic force produced by bending deformation of the C-shaped base functions as a normal force for supporting the chip module

AI summary
An electrical connector includes an upper insulating shell and a lower insulating shell, and at least one conductive terminal. The conductive terminal has an elastic portion located between the upper insulating shell and the lower insulating shell. The elastic portion has a first elastic arm and a second elastic arm. An upper connecting portion is located above the first elastic arm and the second elastic arm and accommodated in the upper insulating shell. The upper connecting portion extends to form an upper contact portion protruding out of the upper insulating shell. A lower connecting portion is located below the first elastic arm and the second elastic arm and accommodated in the lower insulating shell. The lower connecting portion extends to form a lower contact portion protruding out of the lower insulating shell.
