Elastomeric Boot Longitudinal Slots Prevent Air Suction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional weatherproofing systems for coaxial cable connectors face challenges in providing a reliable seal over irregular surfaces and varying connector sizes, leading to air pocket formation and suction issues, which can result in weather-induced degradation and increased replacement costs due to the need for multiple boot sizes and complex installation processes.
Innovation Solution
A weatherproofing boot with longitudinal slots on its inner mold line surface reduces frictional engagement and allows air to escape, preventing suction and facilitating easy installation and removal, while accommodating various connector sizes with multiple diameters and materials like synthetic rubber or silicon-based materials, including a PVC layer to deter bird damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a soft silicone boot/sleeve is used to cover and protect the cable connection, then weather protection is improved, but the boot becomes difficult to install and remove due to air suction on irregular surfaces
Solution Approach 1:
The boot is segmented with longitudinal slots formed into the inner mold line surface, dividing the continuous elastomeric surface into separated sections. This segmentation allows air to escape through the slots during installation and removal, preventing air pockets and suction that would otherwise resist boot movement on irregular connector surfaces.
2Adaptability or versatility
If multiple boots varying in diameter are carried to accommodate different connector sizes, then adaptability is improved, but device complexity and inventory requirements increase
Solution Approach 1:
The boot design with longitudinal slots provides universal adaptability to accommodate connectors of varying sizes and irregular surfaces. The slots enable the boot to expand and contract freely during installation, allowing a single boot design to fit multiple connector types without requiring multiple specialized boots for different diameters.
3Productivity
If a boot is forcibly installed onto a connector, then installation speed is improved, but seal reliability deteriorates due to improperly mated surfaces
Solution Approach 1:
The longitudinal slots are pre-formed into the boot during manufacturing, creating air escape pathways before installation begins. This preliminary action ensures that during rapid installation, air can continuously escape through the slots, preventing vacuum formation that would otherwise resist boot expansion and compromise seal integrity when the boot is forcibly installed.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a flexible, cost-effective, and reliable environmental seal for coaxial cable connections, reducing inventory needs and installation time, while preventing weather and bird-induced damage, thus enhancing the durability and maintenance efficiency of telecommunications equipment.
Implementation Method 1
The longitudinal slots serve as a longitudinal passageway for the movement of trapped air from one IML surface to another so as to prevent the built-up of air and/or inducing a pocket of suction resisting the separation of the boot from the jumper cable
Implementation Method 2
The longitudinal slots function to reduce the surface area of frictional engagement between the intermediate surface and the corresponding peripheral surface of the coaxial cable connector

AI summary
A productive housing for a coaxial cable connector comprising an elastomeric housing disposed over and engaging a connector and having a plurality of longitudinal slots formed into the inner mold line (IML) surface of the elastomeric housing. The longitudinal slots function to reduce the surface area of frictional engagement between the intermediate surface and the corresponding peripheral surface of the coaxial cable connector. The longitudinal slots serve as a longitudinal passageway for the movement of trapped air from one IML surface to another so as to prevent the built-up of air and/or inducing a pocket of suction resisting the separation of the housing from the jumper cable.
