Fibre-Optic Adapter Sleeve for Sealed Connections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fiber optic adapters can only securely connect fiber optic cables with different types of connectors and lack protection against environmental influences for cables with the same type of connector, limiting their application and exposure to moisture.
Innovation Solution
A fiber optic connection arrangement featuring a dual-section adapter with distinct external and internal sections, utilizing external and internal threads for secure alignment and sealing, allowing connection of cables with the same type of connectors while maintaining protection against environmental influences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fiber optic adapter is designed with different connection devices for external and internal cables, then it can securely connect cables with different connector types, but it cannot securely connect two cables with the same connector type
Solution Approach 1:
The adapter is divided into an outer section with a first connection device for external cables and an inner section with a second connection device for internal cables. The outer section can be detached to expose the inner section, allowing the same adapter to securely connect two internal cables with identical connector types by using only the inner connection devices.
2Object-affected harmful factors
If the second connection device is arranged in an inner area not exposed to environmental influences, then internal cables are protected from moisture, but the adapter cannot provide sealed protection for external cable connections
Solution Approach 1:
The adapter is segmented into an outer section and an inner section that can be detached from each other. The outer section includes sealing means that can be engaged to provide a sealed connection for external cables, while the inner section provides protection for internal cables. This segmentation allows the adapter to provide sealed protection for external cable connections when needed.
3Object-affected harmful factors
If sealing means are added to the first connection device for external cables, then moisture protection is achieved, but the device complexity increases
Solution Approach 1:
The outer section is designed with multi-functionality: it provides mechanical connection for external cables, incorporates sealing means for moisture protection, and includes attachment means for detaching from the inner section. This universal design allows a single component to perform multiple functions without proportionally increasing overall device complexity.
