Elastic Sealing Lip for Conductor Moisture Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing plastic sealing covers for conductor connections lack an effective mechanism to ensure a moisture-tight seal, particularly at the interface between conductors, which can lead to moisture penetration and compromised electrical connections.
Innovation Solution
A plastic sealing sleeve with a tapered section and circumferential sealing lip is designed to fit over the conductor, providing a secure seal by contacting the cable sheathing and encasing the connection area, with optional additional sealing methods such as a hinged cover or encapsulation with insulating materials, allowing for easy installation and removal without damaging the connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a rigid sealing sleeve is used, then structural stability is improved, but ease of installation deteriorates
Solution Approach 1:
The sealing sleeve transitions from a rigid structure to a dynamically adaptable one through the elastic sealing lip that can deform during installation and then maintain a stable sealed state, combining ease of installation with structural stability
Solution Approach 2:
The patent employs a flexible sealing lip made of elastomeric material that can conform to the conductor surface, providing both easy installation through flexibility and stable sealing when in contact with the conductor
2Reliability
If a thick-walled sealing casing is used, then sealing effectiveness is improved, but device complexity increases
Solution Approach 1:
The sealing structure is segmented into a simple cylindrical body and a separate sealing lip function, where the thin-walled body provides structural support and the dedicated sealing lip provides the sealing function, reducing overall complexity while maintaining effectiveness
Solution Approach 2:
The sealing lip is concentrated at specific locations (opening edges) rather than distributing thickness throughout the entire casing, providing effective sealing at critical points while keeping the overall structure simple and thin-walled
3Ease of repair
If the sealing sleeve is designed to be removable, then ease of repair is improved, but reliability deteriorates
Solution Approach 1:
The elastic sealing lip provides a dynamic sealing mechanism that maintains reliable contact during normal operation but allows for controlled removal when needed, balancing reliability with ease of repair
Solution Approach 2:
The elastic material of the sealing lip self-adjusts to maintain sealing contact, ensuring reliability, while the overall simple design allows the entire assembly to be easily removed and reinstalled for repairs without special tools or procedures
