Optical Connector Plug Shutter Mechanism Preventing Deformation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical connector plugs with shutters can be deformed or damaged due to weak elastic forces in the coupling claw or improper insertion, especially when the shutter holding member moves to the center of the optical connector adapter, leading to interference between the shielding plate and other components.
Innovation Solution
An optical connector plug with a push-on coupling system featuring a plug frame and a housing that includes a grip member and a shutter holding member, where the shutter member is biased to maintain a shield position in the extension state and transitions to a non-shield position in the reduction state, preventing interference with the optical connector adapter's sleeve holding portion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the shutter holding member is pushed by the coupling claw during insertion, then the shutter member can be moved to expose the ferrule end face, but the shutter holding member may move to the center portion of the optical connector adapter causing the shielding plate to be deformed or damaged
Solution Approach 1:
The patent applies preliminary action by pre-positioning the shutter holding member with its front end at the front side of the optical connector adapter body before insertion occurs. This preliminary positioning ensures that during the insertion process, the shutter holding member cannot move to the center portion of the adapter, thereby preventing the shielding plate from being deformed or damaged while still allowing the shutter to be properly exposed for coupling
2Force
If the elastic force of the coupling claw is weak or the interval of coupling claws is large, then the coupling may be insufficient, but the shutter holding member moves to the center portion causing shielding plate damage
Solution Approach 1:
The patent applies preliminary action by pre-positioning the shutter holding member with its front end at the front side of the optical connector adapter body before insertion occurs. This preliminary positioning ensures that during the insertion process, the shutter holding member cannot move to the center portion of the adapter, thereby preventing the shielding plate from being deformed or damaged even when the coupling claw's elastic force is weak or the interval between coupling claws is large
3Strength
If the optical connector plug is strongly inserted to ensure coupling, then the connection is secure, but the shielding plate is deformed or damaged when the shutter holding member is in the wrong position
Solution Approach 1:
The patent applies preliminary action by pre-positioning the shutter holding member with its front end at the front side of the optical connector adapter body before insertion occurs. This preliminary positioning ensures that during strong insertion, the shutter holding member cannot move to the center portion of the adapter, thereby preventing the shielding plate from being deformed or damaged while still allowing secure coupling
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution ensures the shutter member does not deform or get damaged, even when the shutter holding member passes through the coupling claw, maintaining high safety and preventing light leakage, while allowing easy connection and disconnection without damaging the shutter.
Implementation Method 1
the elastic force of the coupling claw of the optical connector adaptor is weak

AI summary
In an optical connector plug, a front end of the shutter member can move between a shield position to shield a front end face of a ferrule in an extension state and a non-shield position to expose the front end face of the ferrule to the front side of a housing in a reduction state, when a plug frame and a shutter holding member move between the extension state and the reduction state. In the optical connector plug, in a course in which the shutter holding member is engaged with holding portions protruding in an axial direction of the optical connector adaptor and a grip member moves from the extension state to the reduction state, the front end of the shutter member is spaced to face front ends of the holding portions in the axial direction.
