Fiber Optic Adapter Shielding Door That Avoids Fiber Core Contact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fiber optic connectors are prone to damage their fiber core when pushed into adapters, leading to instability, and exposure to communication light can harm the eye, while dust accumulation interferes with connections.
Innovation Solution
A fiber optic adapter design featuring a main body shell with a shielding door assembly, including a door body and an elastic member, where protective protrusions on the door body misalign with the fiber core, and a limiting protrusion prevents excessive rotation, combined with a snap-fitting mechanism for stability and alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a shielding door is used to block the installation passage, then the harmful light exposure and dust accumulation problems are solved, but the fiber core of the fiber optic connector is prone to damage
Solution Approach 1:
The patent introduces protective protrusions as intermediary elements between the fiber optic connector and the door body. These protrusions act as mediators that prevent direct contact between the connector's fiber core and the door body, thereby avoiding damage while still allowing the door to perform its shielding function. The protective protrusions are positioned on the door body to intercept the connector before it can contact the door body's main surface.
Solution Approach 2:
The patent applies protective protrusions only at specific locations on the door body where contact with the fiber optic connector occurs. This localized protection approach ensures that the fiber core is protected from damage while maintaining the overall functionality of the door body for blocking light and dust. The protective features are strategically positioned at the critical interaction points rather than protecting the entire door body uniformly.
2Object-affected harmful factors
If the door body is designed to block the installation passage, then dust accumulation is prevented, but the fiber optic connector may be damaged during insertion
Solution Approach 1:
The protective protrusions serve as intermediary elements that mediate between the fiber optic connector and the door body. During connector insertion, these protrusions make first contact with the connector, preventing the connector from directly contacting the door body's main surface. This intermediary contact allows the door to maintain its blocking function while preventing connector damage through the protective protrusions' distributed contact points.
Solution Approach 2:
The protective protrusions are positioned beforehand on the door body to provide cushioning protection before the fiber optic connector can contact the door body's main surface. This prior cushioning arrangement ensures that when the connector is inserted, the protective protrusions absorb and distribute the contact forces, preventing damage to the connector's fiber core before any harmful contact can occur.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Prevents damage to the fiber core by maintaining a gap between the connector and door body, ensuring stability and preventing dust interference, while protecting against harmful light exposure.
Implementation Method 1
the elastic member connects the door body and the main body shell. When the fiber optic connector abuts against the door body, the door body is squeezed to rotate and open the installation passage, to allow the elastic member to accumulate potential energy to drive the door body to maintain the tendency of blocking the installation passage

AI summary
A fiber optic adapter includes a main body shell and a shielding door assembly. The main body shell has an installation passage. The shielding door assembly includes a door body and an elastic member. The door body is located in the installation passage to block the installation passage; the door body is hinged to the main body shell, and the elastic member connects the door body and the main body shell. Protective protrusions are provided on one side of the door body abutted against by the fiber optic connector, and when the fiber optic connector abuts against the protective protrusions, the protective protrusions are misaligned with a fiber core of the fiber optic connector, the door body is not in contact with the fiber core of the fiber optic connector, and there is a gap between the door body and the fiber core of the fiber optic connector.
