Threaded PCB Connector Ejector for Stuck Terminal Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Printed circuit board connectors often become stuck to terminals, making removal difficult due to lack of space and poor contact, which existing technologies fail to address effectively.
Innovation Solution
A printed circuit board connector ejector with a threaded body and actuation member that facilitates rotation and disengagement of the connector from the board, utilizing a low friction element and gripping features to assist in removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a connector is removed from a printed circuit board connection, then the connector can be reused or replaced, but the connector becomes stuck on the terminals making removal difficult
Solution Approach 1:
The ejector tool serves as an intermediary device between the operator and the stuck connector. It engages with the connector body through the passage and uses the threaded mechanism to apply controlled rotational force, mediating the removal process without requiring direct manipulation of the stuck connector terminals
Solution Approach 2:
The ejector transitions from a static engagement position to a dynamic rotating motion. The threaded passage converts rotational movement into linear extraction force, dynamically adapting the removal mechanism to overcome the static friction and adhesion causing the connector to stick
2Ease of operation
If more space is provided about the connector to enable good contact for removal, then removal becomes easier, but the printed circuit board layout becomes more complex and larger
Solution Approach 1:
The ejector approaches the connector from a lateral dimension through the passage rather than requiring access from the terminal ends. This dimensional shift allows removal operations without needing additional clearance space around the connector terminals on the board surface
3Ease of operation
If the ejector rotates relative to the electrical connector, then the connector can be disengaged from the printed circuit board, but friction between the ejector and connector may cause wear
Solution Approach 1:
The threaded passage replaces direct rotational contact between the ejector and connector. Instead of the ejector rotating against the connector body, the threads convert rotational motion into linear extraction through screw mechanics, reducing sliding friction and wear
