Optical Fiber Connector with Movable Blade for Secure Holding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical fiber connectors either have weak holding power, making them prone to disconnection under moderate force, or are difficult to remove due to piercing mechanisms that embed into the fiber coating.
Innovation Solution
A connector design featuring a movable body and fixing member with a blade that cuts into the protection layer of the optical fiber, allowing secure attachment and easy release by moving between fixed and releasing positions, facilitated by guide grooves and projections for directional control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a cuneate projection is pierced into the coating of the optical fiber, then the holding power is strengthened, but the optical fiber becomes difficult to remove
Solution Approach 1:
The fixing member is designed to be movable between a fixing position (where the blade cuts into the protection layer for strong holding) and a releasing position (where the blade retracts to allow easy removal). This dynamic mechanism resolves the contradiction by allowing the system to switch between strong attachment and easy detachment states based on operational needs.
2Device complexity
If an optical fiber is pressed into an inserting part, then the structure is simple, but the holding power is weak
Solution Approach 1:
The fixing member is divided into a blade portion (for cutting into the protection layer) and a moving portion (for actuation). This segmentation allows the simple pressing action to be converted into an effective cutting action that provides strong holding power while maintaining operational simplicity.

AI summary
When a moving member moves to a fixing position, a fixing member moves to a second fixing position, a blade of the fixing member cuts into a protection layer of a cord, and thereby the cord is fixed. When the moving member moves to a releasing position, the fixing member moves to a second releasing position, the blade leaves the protection layer, and thereby the cord is released.
