Pluggable Module Unlocking Structure for Cable-Attached Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pluggable modules in communication equipment face challenges with the rotation bail type, where modules cannot be plugged or unplugged with cables attached, and the direct-pull type lacks control over the unlocking status, leading to potential misoperations and line failures.
Innovation Solution
An unlocking structure featuring a sliding unlocking plate with a detention edge and a motion block piece, including a reset bulge, along with a push/pull handle that rotates to separate the detention bulge from the detention edge, allowing for module unlocking and resetting while maintaining cable attachment, and incorporating a return spring for automatic resetting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the rotation bail type is used for unlocking, then the module can be securely locked, but the module cannot be plugged or unplugged with cables attached
Solution Approach 1:
The unlocking mechanism is divided into separate functional components: a push/pull handle for operation, an unlocking plate with unlocking edge for engaging the leaf spring, and a motion block piece with detention bulge for controlling the unlocking state. This segmentation allows the module to be unlocked without removing cables while maintaining structural integrity.
Solution Approach 2:
The motion block piece is designed to move between a first position (where the detention bulge detains the unlocking plate) and a second position (where detachment occurs). This dynamic movement enables controlled unlocking while preventing accidental disconnection, allowing cable-attached plugging and unplugging.
2Ease of operation
If the direct-pull type is used for unlocking, then the module can be easily removed, but there is no control over the unlocking status leading to misoperations and line failures
Solution Approach 1:
The motion block piece provides visual and tactile feedback about the unlocking status. When the detention bulge is in the first position, the module is locked; when moved to the second position, the module is unlocked. This feedback mechanism prevents misoperations by making the unlocking state clearly identifiable.
Solution Approach 2:
The motion block piece must be moved to the second position before the module can be removed. This preliminary action ensures that the unlocking process is intentional and controlled, preventing accidental line failures while maintaining easy removal when properly initiated.
3Ease of operation
If the unlocking plate is allowed to slide freely for unlocking, then the module can be unlocked, but accidental removal or dislocation may occur
Solution Approach 1:
The motion block piece in the first position exerts a preliminary anti-action by detaining the unlocking plate, preventing it from sliding backward and causing accidental removal. This constraint is released only when the motion block piece is intentionally moved to the second position, ensuring stable connection during normal operation.
Solution Approach 2:
The motion block piece acts as an intermediary between the push/pull handle and the unlocking plate. It mediates the unlocking process by controlling when the unlocking plate can slide, thereby preventing accidental dislocation while enabling reliable unlocking when needed.

AI summary
An unlocking structure for a pluggable module (1XA) which mainly comprises a push/pull handle (11A), an unlocking plate (12), a casing (13, 14), and a part incorporating a motion block piece (15X). Pushing the push/pull handle (11A) moves the unlocking plate (12) toward the rear end of the casing (13, 14) to unlock the module, and then pulling the push/pull handle (11A) allows the module to be removed; in the unlocked state, the unlocking plate (12) can be reset by means of rotating the push/pull handle (11A). This unlock and reset operation provides a complete operation mechanism for the module, as not only is it able to plug in and unplug the module with cable attached, but also able to conveniently operate a reset in situ, while maximally avoiding misoperations and accidents, and the related operations being simple and easy.
