Optical Connector Stop Ring with Stepped Through-Hole
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Optical fiber cords face challenges with low flex resistance and susceptibility to foreign substances and moisture when the outer jacket is cut to expose the optical fiber, leading to difficulties in using boots with low flexibility and unstable ferrule fixation.
Innovation Solution
An optical fiber cord with a stop ring featuring a through-hole with a stepwisely narrowing diameter from the crimping part to the ferrule side, allowing the optical fiber to be secured without cutting the outer jacket, combined with a crimping ring, ferrule, spring, plug frame, and grip, enhancing flexibility resistance and bending properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the outer jacket is cut to expose the optical fiber, then the optical fiber can be accessed for connection, but the flex resistance decreases and the cord becomes susceptible to foreign substances and moisture
Solution Approach 1:
The stop ring is divided into multiple sections along its longitudinal axis, with each section having a different diameter to create a stepped configuration. This segmentation allows the outer jacket to pass through the larger diameter sections while the optical fiber is secured in the smaller diameter section, eliminating the need to cut the outer jacket while still providing access to the optical fiber for connection.
Solution Approach 2:
The stop ring acts as an intermediary component between the outer jacket and the optical fiber connection point. Its stepped structure provides a transition zone where the outer jacket can pass through intact while the optical fiber is constrained and secured, serving as a mediator that allows fiber access without compromising the protective outer jacket.
2Ease of operation
If the outer jacket is cut to expose the optical fiber, then the optical fiber can be fixed to the ferrule, but the appearance is ruined and foreign substances can invade
Solution Approach 1:
The stop ring's segmented design with varying diameters allows the outer jacket to remain intact while passing through the larger sections. The optical fiber is secured in the smaller diameter section, enabling fixation to the ferrule without cutting the outer jacket, thus preventing foreign substance invasion and maintaining appearance.
Solution Approach 2:
Different sections of the stop ring have different diameters tailored to specific functions: larger diameters for passing the outer jacket intact, and a smaller diameter section for securing the optical fiber. This local differentiation of properties allows the system to achieve fiber fixation while maintaining the protective integrity of the outer jacket.
3Ease of operation
If a boot with exposed optical fiber cord is used, then the connection can be made, but the flexibility is reduced
Solution Approach 1:
The stop ring's segmented structure with progressive diameter changes allows the outer jacket to pass through without cutting, maintaining the boot's flexibility. The optical fiber is secured in the appropriate section, enabling connection capability while preserving the bending properties of the overall assembly.
