Solution Overview
Problem
Existing electricity connectors for LGA chip modules suffer from terminal fatigue leading to unstable connections and complex assembly processes due to the design of C-shaped terminals with elastic arms.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If C-shaped terminals with elastic arms are used to connect LGA chip modules, then electrical connection is achieved, but terminal fatigue occurs after long-term compression leading to unstable connections
Solution Approach 1:
The terminal is divided into distinct functional segments: a contacting portion for electrical contact, a retaining portion for structural support, and an elastic portion for flexibility. This segmentation allows each part to perform its specific function optimally, reducing stress concentration and fatigue in the elastic arms while maintaining connection stability over extended periods
Solution Approach 2:
The patent modifies the terminal structure by changing the geometric parameters and material distribution within the terminal body. The retaining portions are designed with specific shapes that distribute compression forces more evenly, and the elastic portions are optimized for flexibility without excessive deformation, thereby extending the terminal's service life under long-term compression
2Reliability
If C-shaped terminals with elastic arms are used, then electrical connection is established, but assembly between terminals and insulation body becomes comparatively complicated
Solution Approach 1:
The contacting portion, retaining portion, and elastic portion are merged into a single integrated terminal structure rather than separate components. This unified design eliminates the need for complex assembly steps between multiple parts, allowing the terminal to be inserted as one piece into the insulation body while still providing both electrical connection and structural retention functions
Solution Approach 2:
The terminal structure is designed to be self-retaining through its integrated retaining portions that automatically engage with the insulation body upon insertion. The elastic portions provide self-adjusting compression force, eliminating the need for additional fastening mechanisms or complex assembly procedures, thereby simplifying manufacturing while ensuring reliable electrical connection

AI summary
An electricity connector to connect two electronic devices abutted to each other includes an insulation body and multiple conductor terminals, and multiple channels disposed on the insulation body to accommodate the conductor terminals; each conductor terminal including an upper contacting portion, a lower contacting portion, and a retaining portion each on both sides to enable the conductor terminal maintaining better flexibility, warrant improved electricity connection between two abutted electronic devices, and allow easier assembly.
