MPO Push-Pull Boot With Transition Member For Damage-Free Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In densely packed fiber optic connector installations, existing strain relief boots can damage connectors when used to remove them, and smaller connectors become difficult to install and remove due to limited space and tangling of optical fibers.
Innovation Solution
A push-pull boot design for MPO fiber optic connectors featuring a rear portion, middle portion, transition portion, and front extensions with cross bars that engage the outer housing, allowing for secure installation and removal without pinching or damaging the optical fibers or the boot.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If fiber optic connectors become smaller to increase installation density, then the number of connectors that can be installed increases, but it becomes more difficult to install and remove them
Solution Approach 1:
The boot acts as an intermediary tool between the installer and the fiber optic connector. It provides a larger gripping surface area that allows installers to easily grasp and manipulate small connectors without directly handling the delicate connector components, thus resolving the contradiction between increased connector density and ease of installation/removal
Solution Approach 2:
The boot is divided into distinct functional segments: a gripping portion for manual manipulation, a transition portion for force transmission, and a engagement portion with tabs that interface with the connector. This segmentation allows each part to perform its specific function optimally, making the overall system easier to operate despite smaller connector sizes
2Ease of operation
If tabs are attached to outer sleeves for connector removal, then connectors can be easily grasped and removed, but optical fibers become tangled around the tabs
Solution Approach 1:
The boot serves as an intermediary gripping tool that eliminates the need for tabs attached to the connector itself. The tabs are integrated into the boot structure, allowing force application without direct contact with the connector or fibers, thus preventing fiber tangling while maintaining ease of removal
Solution Approach 2:
The boot extends the interaction dimension from direct connector manipulation to boot-mediated manipulation. The tabs extend radially outward from the boot body, providing a larger leverage arm that enables effective connector removal without requiring direct hand contact with the connector or causing fiber entanglement
3Reliability
If boots are used to push connectors into receptacles, then connectors can be securely installed, but pulling on boots may damage connectors if not properly connected
Solution Approach 1:
The boot acts as a safe intermediary for both push and pull operations. The tabs provide a dedicated interface that transmits pulling forces away from the connector body and fibers, ensuring that connectors can be removed without damage even though the boot itself is being pulled
Solution Approach 2:
The boot is pre-positioned over the connector during installation, establishing the force transmission path before any push or pull operations occur. This preliminary positioning ensures that subsequent removal forces are properly directed through the tabs rather than damaging the connector
4Adaptability or versatility
If traditional boots are used without proper connections to outer housing, then boots can be freely designed, but they cannot be used to safely remove connectors
Solution Approach 1:
The boot is designed with multi-functionality: the tabs serve dual purposes of securing the boot to the connector during push operations and providing a gripping interface for safe pull operations. This universal design enables both installation and removal functions without compromising design flexibility
Solution Approach 2:
The boot integrates multiple functions into a single component: strain relief, connector securing, and removal gripping. The tabs merge the securing function with the removal interface function, eliminating the need for separate removal mechanisms and maintaining design simplicity while enabling safe connector removal

AI summary
A push-pull boot for an MPO fiber optic connector has rear portion, a middle portion, a transition portion disposed therebetween, at least two front extensions extending from the middle portion and a cross bar between the at least two front extensions. The push-pull boot has a spine that extends from an end of a rear portion to the transition portion and parallel to a longitudinal axis. The push-pull boot may also have a rear facing surface that is configured to engage a forward facing surface on the outer housing during a pulling operation. It may also have a spring push seat located in the middle portion of the push-pull boot and configured to engage a spring push of the MPO fiber optic connector during a pushing operation of the MPO fiber optic connector.
