Electrical Terminal Interference Lug Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing electrical terminals, especially U-shaped power terminals, are prone to deformation, leading to alignment issues with soldering holes on circuit boards, causing assembly difficulties and poor positioning, especially when multiple power terminals are involved.
Innovation Solution
The electrical terminal and connector design incorporates interference lugs and guiding protrusions to ensure correct positioning and alignment, with interference lugs extending outwardly and guiding grooves to prevent deformation, allowing for secure insertion and fixation within the installation troughs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the U-shaped body is made simple and easy to manufacture, then manufacturing cost is reduced, but the body becomes prone to deformation and positioning accuracy deteriorates
Solution Approach 1:
The terminal body is divided into functional segments: the U-shaped body for basic function, interference lugs for positioning, and guiding grooves for alignment. This segmentation allows each part to perform its specific function while maintaining overall manufacturing simplicity.
Solution Approach 2:
The interference lugs and guiding grooves are pre-formed on the terminal body during manufacturing. This preliminary action ensures that positioning and alignment features are built-in from the start, preventing deformation issues during assembly while keeping the manufacturing process straightforward.
2Device complexity
If the U-shaped body structure is simplified, then device complexity is reduced, but positioning and fixation reliability deteriorates
Solution Approach 1:
The terminal body is divided into functional segments: the U-shaped body for basic function, interference lugs for positioning, and guiding grooves for alignment. This segmentation allows each part to perform its specific function while maintaining overall manufacturing simplicity.
Solution Approach 2:
The interference lugs act as intermediary elements between the terminal body and the installation trough, providing a mechanical interface that ensures reliable positioning without adding complex structures. The guiding grooves similarly mediate the alignment process.
3Manufacturing precision
If interference lugs and guiding grooves are added to improve positioning, then positioning accuracy is improved, but device complexity increases
Solution Approach 1:
Instead of making the entire terminal body complex, the interference lugs and guiding grooves are added only at specific critical locations where positioning and alignment are needed. This local quality approach improves positioning accuracy without significantly increasing overall device complexity.
Solution Approach 2:
The interference lugs extend in a direction perpendicular to the longitudinal axis of the terminal body, adding a dimensional element for positioning that does not require increasing the overall size or complexity of the main body structure.
