Optical Transceiver Latch Mechanism for Smooth Cage Ejection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical transceivers face difficulties in smoothly inserting and ejecting from a cage due to interference between the rotating latch mechanism and other parts of the cage, leading to unstable latching and ejection operations.
Innovation Solution
The optical transceiver design incorporates a slider and latch mechanism where the latch rotates along a shaft intersecting the insertion direction, with a first face engaging the cage and a second face locking the slider, ensuring the latch is restricted during insertion and becomes rotatable during ejection, avoiding interference with other cage parts by maintaining a shorter distance from the housing during rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the latch rotates along a direction intersecting the insertion direction at the center of a shaft, then the latching function is improved, but the latch interferes with other parts of the cage during rotation
Solution Approach 1:
The latch rotation axis is positioned at the center of the shaft, which is located at or beyond the position of the first face engaging the cage. This dimensional positioning ensures that the rotation path of the latch does not extend beyond the cage boundaries, eliminating interference with other cage parts while maintaining effective latching engagement.
2Reliability
If the latch is locked to the slider during insertion, then the latching stability is improved, but the ejection operation becomes difficult
Solution Approach 1:
The latch mechanism transitions between two dynamic states: during insertion, the latch is locked to the slider providing stable latching; during ejection, the latch becomes rotatable allowing smooth operation. This dynamic state change is achieved through the slider's movement relative to the latch, which automatically transitions the latch from a locked to an unlocked state based on the insertion/ejection cycle.
3Object-affected harmful factors
If the shaft position is at the same position as the first face or beyond, then the latch rotation path is reduced avoiding interference, but the latch structure becomes more constrained
Solution Approach 1:
The shaft is positioned at a specific location (center of the shaft at or beyond the first face position) that optimizes the rotation path. This localized positioning creates a quality difference in the latch structure, where the constrained shaft location provides beneficial interference-free rotation while the rest of the latch maintains its functional geometry for effective latching engagement.

AI summary
An optical transceiver which is inserted and ejected with respect to a cage is disclosed. The optical transceiver comprises a slider, a housing supporting the slider to slid the slider along the first direction, and a latch rotating along a second direction intersecting with the first direction at the center of a shaft. The latch has a first face engaging the cage and a second face locking the slider, and is supported by the housing. The latch controls the rotating by locking the second face to the slider when the slider is in a first position, and uncontrols the rotating when the slider is in a second position farther than the first position ejected a direction. A position of the shaft is the same position as a position of the first face or more than a position ejected in case of locking the second face to the slider.
