Ruggedized Fiber Optic Connectors for Multi-Adapter Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fiber optic connectors for outside environmental use lack effective compatibility with various ruggedized adapter configurations, are difficult to install and uninstall, and do not provide adequate environmental sealing and robustness against temperature variations, pulling loads, and side loading.
Innovation Solution
The fiber optic connector system includes a release sleeve and ramped notches for easy insertion and removal, a sealing arrangement with O-ring seals, and a protective shell for environmental protection, allowing compatibility with multiple adapter configurations and enhancing durability and ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If ruggedized fiber optic connectors are designed for outside environmental use, then environmental sealing and robustness are improved, but compatibility with various adapter configurations deteriorates
Solution Approach 1:
The connector body is designed with a standardized interface that can accommodate multiple adapter configurations (SC, LC, ST, etc.) through a universal coupling mechanism. This allows the same ruggedized connector to work with various adapter types while maintaining environmental sealing integrity.
Solution Approach 2:
The connector is divided into modular components including a reusable ruggedized connector body and interchangeable adapter-specific interfaces. This segmentation allows the core environmental protection features to remain consistent while adapting to different connector types through interchangeable elements.
2Strength
If robust fastening arrangements are implemented to withstand pulling loads and side loading, then mechanical strength is improved, but ease of installation and removal deteriorates
Solution Approach 1:
The fastening mechanism transitions from a static rigid connection to a dynamic system with controlled engagement and disengagement phases. During installation, the mechanism allows easy insertion with gradual engagement, while during removal, it provides controlled release to maintain strength during operation but ease of installation.
Solution Approach 2:
The connector incorporates pre-positioned alignment features and guide structures that automatically orient and position the connector during insertion. This preliminary alignment action simplifies the installation process while the subsequent fastening phase provides robust mechanical strength for withstanding loads.
3Strength
If robust fastening arrangements are implemented to withstand side loading, then mechanical strength is improved, but ease of removal deteriorates
Solution Approach 1:
The fastening mechanism employs dynamic characteristics with different engagement levels for installation versus removal. During normal operation, the mechanism maintains strong engagement to resist side loading, while during removal, a release mechanism allows easy disengagement by overcoming a controlled barrier.
Solution Approach 2:
The removal mechanism inverts the engagement approach by using a release action that reverses the installation process. Instead of requiring force to overcome the strong engagement, a simple release action (such as pressing a button or moving a lever) inverts the force direction to facilitate easy removal while maintaining strength during operation.

AI summary
Example fiber optic connector systems have rugged, robust designs that are environmentally sealed and that are relatively easy to install and uninstall in the field. Some connector systems can be configured in the field to be compatible with different styles of fiber optic adapters. Some connectors include a first seal (90) on a release sleeve; and a second seal (88) between the release sleeve and a connector body. Other connectors include a seal (139) and a flexible latch (136) on a connector. Other connectors include a protective structure (228, 328, 428) that mounts over the fiber optic connector. Other connectors include a protective outer shell (528, 860) and a sealing and attachment insert (570, 570A, 876). Other connectors include a protective outer shell (728) and a fastener (780).
