Integrated Optical Fiber Connector Fixing Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing optical fiber connector assemblies with flexible protection members have numerous connection points that are prone to cracking during field installation and use due to the snap-fit connections, leading to reliability issues.
Innovation Solution
A connector assembly featuring a single integrated fixing device with a connection part and a flexible protection part, where the connection part is connected to the rear body of the connector in a snap-fit manner, and the flexible protection part is designed to protect the cable, eliminating intermediate connection points and enhancing durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the flexible protection member includes two flexible half bodies connected in a snap-fit manner to the connector and fixing seat, then the connector assembly can be assembled, but there are too many connection points that easily crack during field installation and use
Solution Approach 1:
The patent combines the two separate flexible half bodies into a single integrated flexible protection member. This eliminates the connection points between half bodies and the connector, and between half bodies and the fixing seat, thereby removing the sources of cracking while maintaining the protective function and assembly capability.
2Ease of operation
If multiple snap-fit connections are used on the flexible protection member, then the connector assembly can be assembled, but the numerous connection points reduce the durability during field installation and use
Solution Approach 1:
The flexible protection member is designed as a single integrated piece rather than multiple connected parts. This eliminates intermediate connection points that would reduce durability, while the snap-fit connection at the single interface with the connector body maintains ease of assembly.
3Ease of manufacture
If the flexible protection member has multiple connection points to the connector and fixing seat, then the assembly can be completed, but the connection points create weak points that crack during installation
Solution Approach 1:
The patent integrates the flexible protection member as a single unified component that eliminates internal connection points. The snap-fit connection is consolidated to a single interface with the connector body, removing multiple weak points and significantly improving crack resistance while maintaining assembly completeness.

AI summary
A connector assembly includes a connector and a fixing device. The connector has a housing, a ferrule mounted in the housing, and a rear body inserted into a rear end of the housing. The fixing device is connected to the rear body of the connector. The fixing device has a fixture formed in a single integrated piece. The fixture includes a connection part located at a front end of the fixture and configured to be connected to the rear body of the connector and a flexible protection part disposed adjacent to the connection part and configured to protect a cable passing therethrough.
