LC Dustproof Adapter Shutter and Slider Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional fiber optic adapters have a large gap between the shutter and the socket, which is not ideal for dust prevention.
Innovation Solution
The LC dustproof adapter features a dustproof mechanism with a shutter and a slider, both equipped with elastic resetting members, which reduces the gap and enhances dust protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a traditional single-shrapnel shutter structure is used, then the device complexity is low, but the gap between the shutter and socket is large resulting in poor dust prevention
Solution Approach 1:
The dustproof mechanism is divided into two independent components: a shutter and a slider. The shutter is rotatably disposed at the bottom of the socket while the slider is slidably disposed at the top. This segmentation allows each component to independently control the gap closure, achieving better dust prevention compared to a single-shrapnel structure.
Solution Approach 2:
The shutter is designed to rotate rather than move linearly, allowing it to dynamically adjust and close the gap more effectively. The rotatable design enables the shutter to conform to the socket geometry and maintain optimal sealing contact, improving dust prevention while managing the complexity through smooth rotational motion.
2Reliability
If elastic resetting members are added to both the shutter and slider, then the reliability of opening and closing is improved, but the device complexity increases
Solution Approach 1:
Elastic resetting members are pre-installed on both the shutter and the slider to automatically restore them to their initial positions after operation. The elastic arm on the shutter and the spring on the slider are configured to exert restoring forces that ensure reliable return to the closed position, improving reliability without requiring complex external resetting mechanisms.
Solution Approach 2:
The elastic resetting members enable the shutter and slider to self-reset to their initial positions after being actuated. The elastic arm and spring automatically generate the restoring force needed to close the gaps, allowing the dustproof mechanism to reset itself without external intervention, thereby improving reliability while keeping the structure relatively simple.
