Receptacle Release Mechanism for Small Plug Connector Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fiber optic communication systems face challenges in delivering high bandwidth capabilities due to the need for pre-terminated cables to pass through narrow paths, requiring smaller plug connectors that can be easily routed and mated without mechanical release mechanisms.
Innovation Solution
A plug receptacle system with a movable plug lock and a release member that allows for the retention or release of plug connectors, utilizing a biasing mechanism and actuation system to facilitate easy insertion and removal, while ensuring proper alignment and orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If pre-terminated cables are threaded through narrow ducts and small holes, then the connector size must be reduced, but the connector becomes harder to grip and manipulate for insertion and removal
Solution Approach 1:
A release member acts as an intermediary between the user and the plug connector. Instead of directly gripping the small connector body, the user actuates the release member which then manipulates the locking mechanism. This intermediary allows indirect control of the connector retention system, solving the problem of how to easily remove small connectors without direct manual manipulation of the connector itself.
2Ease of operation
If a release mechanism is integrated into the plug connector, then the connector can be easily removed, but the connector size increases and it becomes harder to route through narrow paths
Solution Approach 1:
The release function is segmented from the plug connector body and placed in the receptacle. The plug connector remains a simple, compact mating component while the complex release mechanism with moving parts is located separately in the receptacle. This segmentation allows the connector to maintain its small size for easy routing while still providing easy removal capability through the separate release member actuated in the receptacle.
3Volume of moving object
If the plug connector is made smaller to fit narrow ducts, then routing capability improves, but the structural integrity and alignment precision may be compromised
Solution Approach 1:
The locking mechanism provides excessive retention force once engaged, ensuring secure connection despite the small connector size. The release member with biasing mechanism ensures that the locking action is definitive and precise, compensating for the reduced size by providing stronger engagement forces and more precise positioning when locked.

Function Achieved in This Case
Enables efficient routing of optical and electrical connectors through narrow spaces by allowing easy insertion and removal without mechanical protrusions, maintaining connector integrity and alignment.
Implementation Method 1
the plug lock is biased to the locking position... the release member is biased to the non-actuated position... In certain examples, the plug lock is biased to the locking position through a natural resiliency of the material of the plug lock

AI summary
A release member is mounted at the port of a plug receptacle to enable removal of a plug connector from the port. The plug connector is devoid of releasing structure to enable removal of the plug. The release member moves parallel to or coaxial with a plug insertion axis of the port. The release member is biased to a non-actuated position separately from a plug lock being biased to a locking position. The release member can carry a polarity indicator for the port; various shaped actuation sections; and/or a biasing member for the release member.
