Optical Transceiver Receptacle Stop Member for Secure Latch Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Optical transceiver modules face challenges in securely retaining LC connector plugs due to the flexible latch arm's tendency to return to a fully relaxed state, leading to potential disconnection issues.
Innovation Solution
The optical transceiver module housing incorporates a stop member within the receptacle's latchway to restrain the flexible latch arm between its fully flexed and fully relaxed states, preventing the latch arm from fully relaxing and ensuring secure plug retention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the latch arm is allowed to fully relax, then the connector plug can be easily inserted, but the connector plug may become loose or disconnect
Solution Approach 1:
The stop member is positioned in advance within the latchway to prevent the latch arm from returning to its fully relaxed state. This preliminary constraint counteracts the natural tendency of the latch arm to flex outward, ensuring the latch arm remains in a partially flexed, latched position that secures the connector plug while still allowing easy insertion
2Reliability
If the latch arm is restrained in a partially flexed state, then the connector plug is securely retained, but the module profile increases due to latch arm extension
Solution Approach 1:
The stop member is positioned within the latchway at a specific location that constrains the latch arm's movement in the lateral dimension. By strategically placing the stop member, the latch arm is prevented from extending beyond the module's external轮廓, thus maintaining a low profile while still achieving secure retention of the connector plug
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
This solution effectively prevents the LC connector plug from being easily removed, maintaining a secure connection and allowing for closer packing of transceiver modules without latch arm interference, while maintaining a low profile.
Implementation Method 1
latch arm 12 can be flexed from a relaxed or unflexed state shown in solid line to a fully flexed state shown in broken line. The force thus loads latch arm 12 with a return spring force or resilient bias force.

AI summary
An optical communications module includes a receptacle with a stop member. The receptacle has a keyway and a latchway. The keyway is configured to receive and guide a body of the connector plug in a direction along a keyway axis. The latchway is defined by a total flexure range of the flexible latch arm between a fully flexed state and a fully relaxed state. The latchway is configured to receive and guide the flexible latch arm through a range of movement having a directional component perpendicular to the keyway axis. The stop member extends from a wall of the receptacle into the latchway. The stop member is configured to restrain the flexible latch arm in a latched state between the fully flexed state and the fully relaxed state.
