Pluggable Connector Latch Mechanism for Optical Module Testing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable connectors for optoelectronic modules lack the ability to be easily attached and removed, making modular level testing difficult.
Innovation Solution
A pluggable connector system that includes a clip to securely attach and detach a ferrule-based optical cable to an optoelectronic module without disassembling the module, allowing for easy engagement and disengagement of optical fibers with a lens assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cable connector is permanently attached to the optoelectronic module, then connection reliability is improved, but ease of operation for modular testing deteriorates
Solution Approach 1:
The connector employs a latch mechanism that transitions between engaged and disengaged states, allowing the connection to be dynamically changed from permanent to removable as needed. The latch can be actuated to release the connector from the receptacle, enabling easy attachment and removal for modular testing while maintaining secure connection during operation.
2Ease of operation
If the connector structure is simplified for easy attachment, then ease of operation is improved, but device complexity increases to achieve removable functionality
Solution Approach 1:
The connector is divided into separate components including a connector body, latch mechanism, and ferrule assembly. This segmentation allows the complex functionality to be distributed across multiple simple parts that work together, making the overall system easier to manufacture and assemble while providing the required removable attachment capability.

AI summary
In an embodiment, a pluggable connector configured to removably couple an end of an optical cable to an optoelectronic module includes a first portion and a second portion. The first portion is configured to engage a latch slot of the optoelectronic module to retain within the optoelectronic module a ferrule optically coupled to optical fibers of the optical cable. The second portion is configured to engage the ferrule to prevent removal of the ferrule from within the optoelectronic module when the first portion engages the latch slot.
