LC Optical Connector Rigid Latch Mechanism Fatigue
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
LC optical connectors experience fatigue and reduced lifespan due to repeated flexing of flexible members, particularly in high-usage applications like test cords, which limits their operational life.
Innovation Solution
The design incorporates a rigid latch member with a retainer spring and latch retainer system that allows engagement and disengagement without flexing, extending the connector's life by using a rotatable latch mechanism and a duplex clip assembly for secure alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a flexible member is used to couple and decouple the optical connector, then ease of operation is improved, but reliability deteriorates due to fatigue from repeated flexing
Solution Approach 1:
The connector is divided into separate components: a rigid housing, a rigid latch member, and a retainer spring. The flexible member is removed entirely, and the latching function is segmented between the rigid latch member (for engagement) and the retainer spring (for maintaining force), eliminating fatigue while preserving operability.
Solution Approach 2:
Instead of using a flexible member that flexes to engage and disengage, the invention inverts the approach by using a rigid latch member that rotates about a pivot point. The flexibility is transferred to the retainer spring, which maintains engagement force without being the primary actuating element, thereby eliminating fatigue from repeated flexing of the engagement member.
2Reliability
If a rigid latch member with retainer spring is used instead of flexible member, then reliability is improved by eliminating fatigue, but device complexity increases
Solution Approach 1:
The retainer spring and latch member are combined into an integrated assembly where the spring is attached to the latch member. This merging reduces the number of separate components and simplifies the overall structure while maintaining the reliability benefits of the rigid latch mechanism with spring-loaded engagement force.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution enhances the durability and longevity of LC optical connectors by eliminating the need for flexible members to engage and disengage, thereby reducing wear and tear, and allows for secure and reliable alignment of fiber optic cables.
Implementation Method 1
a retainer spring having a first end abutting the housing and a second end abutting the latch member. The retainer spring is configured to provide a force that pushes the second end of the latch member away from the housing.
