Waterproof Optical Fiber Connector Assembly Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing waterproof optical fiber connectors are difficult to assemble and disassemble due to their complex designs, which hinder efficient connection and disconnection in outdoor environments with dust and moisture.
Innovation Solution
The design incorporates a fiber joining head, sleeve, housing, frame, cover, and boot forming a housing assembly with latching and unlocking mechanisms that allow for easy assembly and disassembly by guiding the optical fiber connector onto an adapter using latching and elastic arms, ensuring secure and error-free connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a waterproof case is used to protect the optical fiber connector from dust and moisture, then the reliability is improved, but the ease of operation deteriorates because assembly and disassembly become difficult
Solution Approach 1:
The waterproof connector is divided into separate components: a waterproof case, a connector body, and a protective cover. The connector body can be assembled and disassembled independently while the waterproof case remains sealed, allowing easy operation without compromising waterproof protection.
Solution Approach 2:
A protective cover acts as an intermediary element that seals the waterproof case when the connector is not in use, maintaining waterproof protection while allowing the connector body to be easily assembled and disassembled from the adapter.
2Reliability
If a complex design with multiple components is used to ensure waterproofing and secure connection, then the reliability is improved, but the device complexity increases making assembly and disassembly difficult
Solution Approach 1:
Multiple functions are merged into the connector body: the latching mechanism, alignment features, and connection interface are integrated into a single component that can be assembled and disassembled as one unit, reducing the effective complexity during operation while maintaining reliable waterproof connections.
Solution Approach 2:
The latching arm provides dynamic locking and unlocking functionality through simple mechanical movement. The elastic arm automatically engages with the adapter to secure the connector during assembly and can be easily released during disassembly, simplifying the operation despite the presence of multiple components.
3Reliability
If a latching mechanism is added to secure the connector to the adapter, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The latching mechanism is designed to automatically engage with the adapter when the connector is inserted, securing the connection without requiring additional manual operations. The elastic arm self-activates through the insertion motion itself, providing reliable locking with minimal added complexity.

AI summary
A waterproof optical fiber assembly includes an optical fiber connector mating with an optical fiber adapter. The optical fiber connector includes a fiber joining head, a sealing member, a sleeve, a housing, and a boot. The sleeve defines an annular groove for receiving the sealing member and two latching protrusions adjacent to the annular groove, the housing defines two unlocking grooves for the two latching protrusions, the fiber joining head is sleeved in the sleeve adjacent to the annular groove, the housing is fitted around an end of the sleeve away from the fiber joining head. The optical fiber adapter includes an assembling seat including a base board, a barrel, and two elastic arms.
