Solution Overview
Problem
Existing fiber optic connector light shielding structures are complex, difficult to assemble, and costly due to multiple parts and soft materials like plastics, silica gel, or rubber, which hinder marketability and automatic assembly.
Innovation Solution
A light screen comprising a metal framework with integrally formed first and second metal spring tabs, forming a spring tab opening-closing structure for light shielding, made of sheet metal for strength and ease of assembly, with a simple structure and production technique.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a light shielding structure with pivot gate and torsion spring is used, then light shielding function is achieved, but device complexity increases and assembly difficulty increases
Solution Approach 1:
The patent combines the light shielding function and the return function into a single integrated light screen structure. The light screen includes a shielding portion for light shielding and a return portion that automatically returns to the original position after being pushed by the connector plug, eliminating the need for separate pivot gate and torsion spring components.
Solution Approach 2:
The light screen serves multiple functions: it provides light shielding when the connector plug is not inserted, and simultaneously acts as a return mechanism to automatically return to the original position after being pushed. This multi-functional design replaces the complex combination of pivot gate and torsion spring.
2Reliability
If soft materials like plastics, silica gel or rubber are used for light screen, then light shielding is achieved, but ease of assembly decreases and cost increases
Solution Approach 1:
The patent changes the material parameter from soft materials (plastics, silica gel, rubber) to hard metal material. The light screen is made of metal with appropriate elasticity, providing better mechanical properties for automatic assembly while maintaining light shielding functionality.
Solution Approach 2:
The light screen uses metal material that combines rigidity for structural stability with elasticity for the return function. This metal composite structure provides both light shielding capability and automatic return functionality without requiring additional soft material components.
