Cable Connecting Assembly Multi-Seal Water Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cable connecting assemblies fail to prevent water and moisture from entering in humid environments, leading to potential damage to cables.
Innovation Solution
The proposed cable connecting assembly features a hollow barrel member with an internal thread, a tubular member with annular grooves for seal rings, and a securing member with a coupling portion and abutment portion, along with multiple seal rings to create multiple barriers against water and moisture entry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single seal ring is used in the conventional cable connecting assembly, then the structure is simple, but water and moisture can still enter the accommodating space and receiving space in humid environments
Solution Approach 1:
The patent divides the sealing function into multiple segments by using three separate seal rings (first seal ring, second seal ring, and third seal ring) positioned at different locations. Each seal ring addresses specific potential leakage paths, collectively providing comprehensive sealing protection against water and moisture entry.
Solution Approach 2:
Different seal rings are positioned at different critical locations within the assembly to address local sealing needs. The first seal ring seals between the barrel member and tubular member, the second seal ring seals at the securing member interface, and the third seal ring provides additional sealing, ensuring each vulnerable area has appropriate sealing quality.
2Reliability
If multiple seal rings are added to prevent water and moisture entry, then sealing performance is improved, but the device complexity increases
Solution Approach 1:
The patent integrates multiple sealing functions into a unified sealing system where three seal rings work together in coordination. Rather than treating each sealing need as separate, the design merges them into a cohesive multi-barrier sealing architecture that prevents water and moisture through combined action.
Solution Approach 2:
The multiple seal rings are positioned in advance at critical interfaces to prevent water and moisture entry before it can reach the cable. This proactive sealing approach creates multiple preventive barriers that cushion against potential leakage paths before harmful effects occur.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration effectively prevents water and moisture from entering the accommodating and receiving spaces, thereby protecting the cable from damage.
Implementation Method 1
The seal unit includes two first seal rings that are respectively disposed in the annular grooves of the tubular member and that sealingly contact an inner surface of the main body of the barrel member, and a second seal ring that is sleeved on the coupling portion of the securing member and that sealingly contacts the inner surface of the main body and the abutment portion of the securing member

AI summary
A cable connecting assembly includes a tubular member, a securing member, a seal unit, and a hollow barrel member that defines an accommodating space. The tubular member is disposed in the accommodating space and has two annular grooves. The securing member has a coupling portion abutting against the tubular member and threadedly engaging the barrel member, and an abutment portion abutting against the barrel member. The seal unit includes two first seal rings respectively disposed in the annular grooves and sealingly contacting an inner surface of the barrel member, and a second seal ring sleeved on the coupling portion of the securing member and sealingly contacting the inner surface of the barrel member and the abutment portion of the securing member.
