Cylindrical Optical Adapter with Bayonet Locking for Size Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical communication modules face challenges in size reduction due to the need for protective sleeve cases and latch mechanisms, which limit the fit between optical receptacles and plugs and increase the risk of foreign matter intrusion and axis misalignment.
Innovation Solution
A cylindrical adapter with a first groove and locking structure, including protrusions and recesses, is used to securely attach an optical plug to an optical communication module, allowing for bayonet mounting and easy detachment, while a split sleeve ensures efficient fiber alignment and protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If protective sleeve cases and latch mechanisms are provided, then protection against foreign matter intrusion and maintenance of fit between optical receptacle and plug is improved, but device size increases and size reduction is limited
Solution Approach 1:
The adapter integrates multiple functions into a single component: it provides protective coverage for the fiber stub and sleeve, incorporates the latch mechanism for maintaining fit, and serves as the structural interface for bayonet mounting. This merging eliminates the need for separate protective sleeve cases and reduces overall device volume while maintaining reliability.
Solution Approach 2:
The adapter serves multiple purposes simultaneously: it protects the optical components, provides mechanical locking through its latch mechanism, enables secure attachment via bayonet mounting, and maintains precise alignment. This multi-functionality reduces the number of separate components needed, thereby reducing device size while improving protection.
2Reliability
If protective sleeve cases and latch mechanisms are provided, then fit between optical receptacle and plug is maintained, but ease of operation for quick connection and detachment is reduced
Solution Approach 1:
The latch mechanism transitions from a static restrictive structure to a dynamic system that can be easily actuated. The bayonet mounting design allows for quick insertion and secure locking, while the latch can be manually actuated for easy detachment. This dynamic design maintains reliable fit during operation while enabling ease of connection and detachment when needed.
3Reliability
If conventional structures with multiple components are used, then protection is improved, but manufacturing complexity and assembly difficulty increase
Solution Approach 1:
The adapter consolidates multiple protective and functional components into a single integrated structure. The body, latch mechanism, and mounting features are all part of one piece, reducing manufacturing steps and assembly complexity while maintaining the protection against foreign matter that would otherwise require multiple separate components.

AI summary
An adapter is cylindrical and includes a first groove and a locking structure. The first groove is adjacent to an inner peripheral surface at one end of the adapter. The first groove extends in an axial direction of the adapter and turns in a circumferential direction. The locking structure is disposed in a circumferential direction at an outer peripheral surface at other end of the adapter. An optical plug includes an elastic member and a stopper. The elastic member is at a rear end of a holder. The stopper includes an annular portion that is in contact with the elastic member and arm portions bent toward the front end from an outer periphery of the annular portion. Each of the arm portions includes a hook at a front end of the stopper. The hook is configured to be locked into the adapter. The optical plug is attached via the adapter.
