Closure Sealing Lever Mechanism for Compact Cable Compression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current sealing systems for telecommunications closures, while effective to some extent, still require improvements in environmental protection against moisture and contaminants, particularly in efficiently compressing and activating seals for pressure and water tightness.
Innovation Solution
A lever mechanism with hinge elements, leveraging elements, arm sections, biasing elements, and a handle is introduced, allowing the mechanism to transition from a non-actuated to an actuated position to couple with a spring-activated element and seal the closure, featuring a compact design with a stroke length less than 20 millimeters and pivotal engagement with a pre-loaded spring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional sealing system is used for telecommunications closures, then the closure provides basic environmental protection, but the sealing effectiveness against moisture and contaminants is insufficient
Solution Approach 1:
The sealing mechanism is pre-loaded with a spring that stores energy in advance. When activated, this pre-stored energy is released to compress the seal against the closure body, ensuring immediate and effective sealing action without requiring external power or complex actuation systems.
Solution Approach 2:
A lever mechanism serves as an intermediary between the activation force and the seal compression. The lever amplifies the applied force and translates it into the necessary compression motion, while the spring acts as an intermediary energy storage element that ensures consistent sealing force.
2Volume of moving object
If a compact sealing mechanism is designed with stroke length less than 20 millimeters, then the device size is reduced, but the force required to activate the seal must be precisely controlled
Solution Approach 1:
The sealing mechanism incorporates a spring element that provides dynamic force characteristics. The spring constant is selected to match the compact stroke length, creating a force-displacement relationship that achieves adequate seal compression within the limited 20mm stroke while maintaining controllable activation forces.
Solution Approach 2:
The spring pre-load force and lever arm ratios are optimized to transform a manageable activation force into sufficient seal compression force within the compact 20mm stroke constraint. This parameter optimization allows the small mechanism to generate the necessary sealing force despite its limited travel distance.

AI summary
A lever mechanism for sealing a telecommunications closure includes a plurality of hinge elements; a leveraging element extending upwardly from each hinge element; an arm section extending from the leveraging element; a biasing element downwardly extending from the arm section; and a handle coupled to the biasing element such that upon application of a compressive force to at least a portion of the handle, each hinge element, each leveraging element, each arm section, and each biasing element moves, allowing the lever mechanism to change from a non-actuated position to an actuated position. The lever mechanism is further configured to couple with a spring-activated element and environmentally seal the telecommunications closure.
