Fiber Optic Connector Assembly for Multi-Style Ruggedized Interfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fiber optic connectors lack versatility in compatibility with different styles or types of fiber optic connectors or adapters, and there is a need for secure and reliable assembly features to ensure proper connection and environmental sealing.
Innovation Solution
A system for making fiber optic connectors that allows pre-terminated cables to be configured with various shrouds, housings, and fasteners, including turn-to-engage fasteners, snap-fit fasteners, and different sealing arrangements, with retention arrangements and boot configurations for strain relief and secure assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a pre-terminated fiber optic cable is made compatible with multiple connector styles through selective mounting of different outer assemblies, then the adaptability and versatility of the connector system is improved, but the device complexity and assembly difficulty increase
Solution Approach 1:
The connector core assembly is designed with a universal interface that can accommodate multiple styles of outer assemblies (shrouds, housings, fasteners). The core contains standardized mounting features including threaded holes, bayonet-style engagement surfaces, and snap-fit receptacles that work with different connector configurations, allowing a single core design to support various connector types through interchangeable outer components.
Solution Approach 2:
The fiber optic connector is divided into separable components: a pre-terminated connector core assembly and interchangeable outer assemblies. This segmentation allows the core (containing the terminated fiber) to remain fixed while different outer assemblies are selectively mounted to achieve compatibility with various connector styles, simplifying the overall system by separating the fixed termination function from the variable interface function.
2Reliability
If robust fastening arrangements and environmental sealing are added to ruggedized fiber optic connectors, then the reliability and durability for outdoor use is improved, but the ease of assembly and manufacturing complexity deteriorate
Solution Approach 1:
The sealing function is merged with the fastening mechanism. The outer assemblies include integrated seals (such as gaskets or sealing rings) that are incorporated into the fastening structure itself, so that when the robust fastening arrangement is assembled, the sealing action occurs simultaneously. This eliminates the need for separate sealing components and steps, maintaining reliability while simplifying manufacturing.
Solution Approach 2:
Sealing surfaces and sealing elements are pre-positioned and pre-configured on the outer assemblies before final assembly. The sealing interfaces are designed with alignment features that ensure proper positioning automatically during assembly, so that the sealing function is established as part of the fastening process rather than requiring separate precision alignment steps.
