Optical Fiber Connector Latch for Reversible Polarity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical fiber connectors for duplex cables are often unidirectional, making it cumbersome and time-consuming for installers to correct cross-over errors between transmitting and receiving cables, and difficult to remove connectors from high-density panels due to limited space and complex locking mechanisms.
Innovation Solution
A connector design featuring a latch with a curved profile that can be unlocked by applying a biasing force through a boot, allowing for reversible polarity and easier removal by changing the length and curvature of the latch, facilitating easier installation and removal without the need for complex reorientation or replacement.

Engineering Contradiction Analysis
1Reliability
If traditional unidirectional connectors are used, then connection stability is improved, but ease of operation deteriorates when polarity correction is needed
Solution Approach 1:
The connector transitions from a static unidirectional design to a dynamic bidirectional design. The housing and latch mechanism are designed to allow insertion and locking in either orientation (0 degrees or 180 degrees), enabling polarity correction by simply removing and reinserting the connector in the opposite orientation without requiring replacement or complex reconfiguration.
2Area of stationary object
If high-density panel configurations are used, then space utilization is improved, but ease of operation deteriorates for connector removal
Solution Approach 1:
The latch mechanism incorporates a curved profile (arc shape) rather than a straight linear design. This curved geometry allows the latch to be actuated from multiple angular directions, enabling operators to access and manipulate the latch from various angles in tight spaces around high-density panel connectors, thereby improving ease of removal despite limited workspace.
3Ease of manufacture
If straight latch profiles are used, then manufacturing simplicity is improved, but force requirements worsen for unlocking
Solution Approach 1:
The latch is designed with a curved arc profile instead of a straight line. This curvature provides mechanical advantage by distributing the unlocking force along an arc path, reducing the peak force required at any single point. The curved geometry also allows for more gradual engagement and disengagement, making the unlocking process easier while maintaining manufacturing feasibility through standard molding techniques.

AI summary
A connector for optically connecting an optical fiber to an optical fiber port at a leading edge of the connector, the connector comprising: a housing configured to receive the optical fiber; a latch coupled to the housing and extending from the housing toward the leading edge of the connector; and a handle coupled to the latch, the handle operable to move the latch between locked and unlocked positions with respect to the optical fiber port, wherein moving the handle away from the leading edge of the connector unlocks the latch from the optical fiber port.
