Swivel Jacket Optical Connector for Field Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical connector parts face difficulties in accessing the welding point and require complex assembly and precise manufacturing, necessitating well-trained personnel for field assembly, especially due to the challenge of centering and fixing the optical fiber and applying adhesive under field conditions.
Innovation Solution
A plug part with a sleeve-like pin holder featuring swiveling jacket parts and an adhesive layer for simplified assembly, allowing easy access to the welding point and protection against mechanical stress and environmental influences, using a pin receiving section and an optical waveguide receiving section with a joint for pivoting and a protective film to handle the adhesive layer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the connector part uses a conventional fixed structure, then the manufacturing precision is maintained, but the accessibility of the welding point deteriorates
Solution Approach 1:
The connector part employs a swivel joint that enables the optical waveguide receiving section to rotate between an operational position (angled relative to the plug pin) and a transport position (aligned with the longitudinal axis). This dynamic positioning allows the welding point to be easily accessible during operation while maintaining a compact, simple structure during transport and installation.
2Ease of manufacture
If the adhesive layer is applied under field conditions, then the assembly flexibility is improved, but the manufacturing precision and reliability deteriorate due to contamination risks
Solution Approach 1:
The adhesive layer is pre-applied to one of the jacket parts during factory manufacturing, protected by a release film. This preliminary action ensures precise, contamination-free adhesive application under controlled factory conditions, while still allowing flexible field assembly by simply removing the release film and joining the parts.
3Strength
If the jacket parts are designed to firmly enclose the optical waveguide, then the protection against mechanical stress is improved, but the accessibility for welding deteriorates
Solution Approach 1:
The jacket parts are designed with a swivel joint that allows them to rotate between a closed position (providing firm enclosure and protection of the welding point) and an open position (providing easy accessibility to the optical fiber end for welding operations). This dynamic design resolves the contradiction between protection and accessibility.
4Manufacturing precision
If the connector part requires precise manufacturing, then the manufacturing precision is improved, but the ease of manufacture deteriorates
Solution Approach 1:
The optical fiber is pre-centered and pre-fixed in the plug pin during factory pre-assembly, achieving precise manufacturing under controlled conditions. This preliminary action eliminates the need for complex centering and fixing operations during field assembly, significantly simplifying the manufacturing process while maintaining high precision.
