Power Terminal Widened Thinner Lower Section Embedding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors face challenges in embedding power terminals effectively due to their design, which often results in inadequate current conduction and unreliable connections between terminals.
Innovation Solution
The electrical connector features power terminals with a widened section that is thinned and lowered, allowing for easier embedding and reliable contact with adjacent grounding terminals, while maintaining a consistent thickness with signal and grounding terminals for proper exposure and connection.

Engineering Contradiction Analysis
1Reliability
If the power terminal is widened for large current conduction, then the current conduction capability is improved, but the embedding process becomes difficult and the terminal thickness becomes inconsistent
Solution Approach 1:
The power terminal is designed with a stepped structure that extends in multiple dimensions: it widens horizontally for current conduction, thins vertically to match adjacent terminal thickness, and lowers its bottom surface to enable proper embedding. This multi-dimensional geometric configuration allows the terminal to achieve large current conduction capability while maintaining ease of manufacture and consistent thickness with adjacent terminals.
2Reliability
If the power terminal is widened for large current conduction, then the current conduction capability is improved, but the terminal thickness becomes inconsistent with adjacent terminals
Solution Approach 1:
The power terminal features a stepped structure where different sections have different thicknesses: the upper portion is thinned to match the thickness of adjacent grounding and signal terminals for consistent exposure, while the lower portion maintains greater thickness to provide adequate current conduction capability. This local differentiation of thickness allows the terminal to simultaneously achieve both current conduction performance and thickness consistency with adjacent terminals.
3Reliability
If the power terminal is lowered for proper embedding, then the embedding reliability is improved, but the terminal structure becomes more complex
Solution Approach 1:
The stepped structure of the power terminal combines multiple functions into a single integrated component: the widened section provides current conduction, the thinned section ensures consistent thickness with adjacent terminals, and the lowered bottom surface enables proper embedding. By merging these multiple geometric features into one stepped structure, the design achieves high embedding reliability without requiring additional separate components or complex assembly steps.
