Segmented Sealing Perimeter for Telecommunication Cable Closures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sealing systems for telecommunication closures, particularly dome-type closures, face challenges in providing a comprehensive and effective sealing solution for cables and perimeter areas, leading to potential environmental exposure and contamination.
Innovation Solution
The integration of an endcap with slotted areas and sealing segment assemblies, comprising inner and outer segments that mate to form a continuous sealing perimeter and seal cables routed through cable port openings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional sealing systems are used in telecommunication closures, then the structure is simpler and easier to manufacture, but the sealing effectiveness is insufficient and allows environmental contaminants to enter
Solution Approach 1:
The sealing system is divided into multiple sealing segments (first sealing segment, second sealing segment, third sealing segment) that are positioned in different slotted areas of the endcap. Each segment independently seals specific cable ports, and together they form a comprehensive sealing barrier. This segmentation allows the system to achieve superior sealing effectiveness while maintaining manageable complexity through modular design.
2Stability of the object's composition
If multiple sealing segments are used to cover all cable ports, then the sealing perimeter becomes more continuous and effective, but the device complexity increases
Solution Approach 1:
The sealing segments are designed with multi-functional capabilities. Each sealing segment can seal multiple cable ports simultaneously and can be positioned in different slotted areas depending on the configuration needs. The segments incorporate both inner and outer portions that work together to provide comprehensive sealing. This universality reduces the total number of components needed while achieving continuous sealing perimeter coverage.
3Adaptability or versatility
If sealing segments are positioned in slotted areas of the endcap, then the sealing system adapts better to different cable configurations, but the manufacturing precision requirements increase
Solution Approach 1:
The endcap is designed with multiple discrete slotted areas that can accommodate different numbers and configurations of sealing segments. This segmentation allows the sealing system to be configured for various cable port arrangements without requiring custom manufacturing for each configuration. The modular slot design enables flexible assembly while maintaining reasonable manufacturing tolerances.
Solution Approach 2:
The sealing segments are designed to be movable and repositionable within the slotted areas of the endcap. This dynamic positioning capability allows installers to configure the sealing segments according to different cable routing requirements. The segments can be adjusted during installation to achieve proper sealing without requiring high-precision pre-positioning, thereby reducing manufacturing precision requirements.

AI summary
A sealing system for a telecommunication closure includes an endcap having a plurality of slotted areas defined therein; and a plurality of sealing segment assemblies mounted to the endcap that when combined form a substantially continuous sealing perimeter around the endcap. Each sealing segment assembly is disposed in one of the plurality of slotted areas and includes an inner segment and an outer segment that when mated together are configured to seal at least one cable routed through a cable port opening.
