Cable Sealing Module Structure for Re-Enterable Enclosure Seals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing telecommunications enclosures face challenges in effectively sealing cables while allowing re-entry without destruction, particularly in maintaining moisture and contaminant exclusion.
Innovation Solution
The development of cable sealing modules with sealant containment walls and pressurization structures that include overlapping mechanical interfaces, threaded fasteners, elastomeric resilient sheets, and linear combs to provide secure and adaptable sealing for cables of varying sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If pressurized gel-type seals are used to seal cable locations, then moisture and contaminant exclusion is improved, but the enclosure cannot be re-entered without destruction
Solution Approach 1:
The sealant containment structure is divided into multiple separable wall portions (first wall portion, second wall portion, third wall portion, fourth wall portion) that can be detached from each other. This segmentation allows the enclosure to be opened and re-entered without destroying the sealant, as the walls can be separated to access cables and then reassembled to restore the seal.
2Ease of manufacture
If a fixed sealant containment structure is used, then manufacturing simplicity is improved, but adaptability to different cable sizes is reduced
Solution Approach 1:
The sealant containment structure incorporates movable and adjustable elements, including the separable wall portions that can be configured in different arrangements. This dynamic design allows the same basic structure to adapt to different cable sizes and configurations while maintaining a relatively simple manufacturing process for each individual component.
