Board-to-Board Connector Grip Member for Damage-Free Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing printed wiring board connection structures risk damaging the boards during connection and disconnection operations due to the mechanical stress applied.
Innovation Solution
A board-to-board connector system with a grip member and spacers that allows for controlled insertion and withdrawal of terminals, preventing damage by distributing the force efficiently and ensuring accurate alignment and depth of insertion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If boards are pushed downward to make connection via interboard connector or lifted upward to break connection, then connection and disconnection operations can be performed, but boards may be bent and damaged during these operations
Solution Approach 1:
The grip member serves as an intermediary tool between the operator and the board. Instead of directly pushing or lifting the board, the operator grips the grip member which transmits the force to the board through the connector assembly. This intermediary structure distributes the mechanical stress and provides better control, preventing board damage during connection and disconnection operations
2Productivity
If force is applied directly to the board for connection operations, then connection can be made, but the board may be damaged due to concentrated stress
Solution Approach 1:
The grip member is divided into multiple functional segments: a grip portion for operator handling, connection portions for engaging the connector, and an extension portion for force transmission. This segmentation allows each part to perform its specific function efficiently - the grip portion provides leverage, the connection portions engage the connector terminals, and the extension portion transmits force along the connector axis, distributing stress away from the board
