Electrical Contact with Curved Solder Joint for CPU Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical contacts lack flexibility in adjusting the horizontal offset relation between the contacting region and the solder pad, making them less adaptable to different CPUs and PCBs.
Innovation Solution
An electrical contact with a planar main body, a supporting arm, a curved spring arm, and a solder part with a vertical section and horizontal solder pad, allowing for adjustable angle adjustments between the solder part's components to accommodate various CPU and PCB configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the solder part is rigidly connected to the main body, then the manufacturing precision is improved, but the adaptability to different CPU and PCB configurations deteriorates
Solution Approach 1:
The solder part is designed with a curved connection section that enables flexible angle adjustment between the vertical section and horizontal solder pad. This dynamic adjustment capability allows the electrical contact to adapt to different offset arrangements between the contacting region and solder pad, while maintaining manufacturing precision through controlled flexibility in the curved connection section.
Solution Approach 2:
The curved connection section allows changing the angle parameter between the vertical section and horizontal solder pad. By adjusting this angle parameter, the electrical contact can accommodate different CPU and PCB configurations with varying offset relations, resolving the contradiction between fixed positioning precision and adaptive versatility.
2Device complexity
If the solder part has fixed angle configuration, then the device complexity is reduced, but the ease of operation for alignment deteriorates
Solution Approach 1:
The curved connection section provides controlled flexibility that enables angle adjustment during assembly operations. This dynamic feature improves ease of operation for alignment without significantly increasing device complexity, as the flexibility is integrated into the existing solder part structure rather than adding separate adjustment mechanisms.

AI summary
An electrical contact includes a main body, a supporting arm extending upwardly from an upper edge thereof, and a spring arm extending curvedly and upwardly from a lower edge thereof with a contacting region at a free end. The spring arm will contact the supporting arm when the spring arm is downwardly pressed by the CPU. A solder part is sidewardly connected to a downward extension formed on a lower portion of the main body and located beside the spring arm, and includes a vertical section extending from the side edge of the downward extension, a horizontal solder pad extending from a lower edge of the vertical direction wherein a curved joint is formed between the downward extension and the vertical section for easy adjusting the angle formed between the downward extension and the vertical section, thus being adapted to fit different CPUs and PCBs.
