Fiber Optic Mounting Bracket With Adjustable Cable Clearance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mounting bracket systems for fiber optic drop terminals are not versatile enough to accommodate various terminal sizes, do not allow for adjustable distance between the terminal and overhead cables, and lack adequate storage for excess fiber optic cables.
Innovation Solution
A mounting bracket system that includes a telecommunications enclosure with a removable cover and a base featuring a mechanical interface, paired with a mounting bracket arrangement that has a main bracket, an aerial strand mount unit, and a cable storage unit. The system allows for selective orientation of the enclosure, adjustable positioning relative to overhead cables, and storage of excess cables through coiled configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional mounting brackets are used, then mounting functionality is provided, but they cannot accommodate various drop terminal sizes
Solution Approach 1:
The mounting bracket is designed with a universal interface system comprising a bracket body with a first interface and a terminal interface with a second interface that mates with the first. The interface includes positioning features such as protrusions and recesses that enable the same bracket design to accommodate multiple drop terminal sizes through standardized coupling mechanisms, eliminating the need for size-specific bracket variations.
2Ease of operation
If fixed mounting distance is used, then installation is simplified, but access and ventilation of the drop terminal are compromised
Solution Approach 1:
The mounting bracket incorporates an adjustable mounting distance mechanism featuring a first mounting position and a second mounting position relative to the overhead cable. The bracket can be positioned at different distances from the cable to optimize access and ventilation requirements, transforming a static mounting system into a dynamic one that adapts to operational needs.
3Adaptability or versatility
If no cable storage is provided, then the mounting structure remains simple, but excess fiber optic cable cannot be stored at the site
Solution Approach 1:
The mounting bracket integrates a cable storage unit directly into the bracket structure, combining the mounting function with the cable storage function in a single integrated component. The storage unit is positioned adjacent to the drop terminal mounting area, allowing excess fiber optic cable to be stored at the installation site without requiring separate storage infrastructure.

AI summary
A fiber optic system includes an enclosure and a mounting bracket that cooperate to define a mechanical coupling interface including a slide interface and a snap-fit interface. The slide interface allows the enclosure to mount to the bracket along a first dimension and retains the enclosure at the bracket along second and third dimensions that are transverse to the first dimension and transverse to each other. The snap-fit interface, once triggered, retains the enclosure at the bracket along the first dimension.
