Connector Assembly Sealing for Wet Locations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connector assemblies for wet locations are susceptible to contamination from dust and moisture due to inadequate sealing between components, which compromises the protection of electrical and mechanical components.
Innovation Solution
A connector assembly comprising a cylindrical connector body, compression ring, compression nut, and sealing ring, where the compression nut presses against the compression ring, and the sealing ring forms a superior seal against the connector body and conduit, using threaded and irregular surfaces for secure gripping and enhanced compression, and optionally including a gasket, locknut, and bushing for additional protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a connector assembly is used to join conduits and components, then electrical and mechanical components can be connected through various angles and configurations, but the components are susceptible to contamination from dust and moisture due to inadequate sealing
Solution Approach 1:
The connector assembly is divided into multiple functional components: connector body, compression ring, compression nut, and sealing ring. Each component performs a specific function, with the sealing ring specifically dedicated to preventing contaminant ingress while the other components handle mechanical connection and compression functions.
Solution Approach 2:
A sealing ring is introduced as an intermediary component between the connector body and the conduit. This sealing ring acts as a mediator that specifically addresses the contaminant protection function without interfering with the mechanical connection capabilities of the other components.
2Object-affected harmful factors
If a sealing ring is added to improve contaminant resistance, then protection against dust and moisture is enhanced, but the device complexity increases
Solution Approach 1:
The connector assembly components are designed to serve multiple functions. The compression ring both secures the conduit and provides a mounting surface for the sealing ring. The connector body serves as both the structural housing and the sealing surface. This multi-functionality reduces the need for additional separate components.
Solution Approach 2:
The sealing function is merged into the existing connector structure rather than being a completely separate system. The sealing ring integrates with the compression mechanism, where the same compression force that secures the conduit also activates the sealing function, combining two protective functions into one integrated system.
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 assembly provides superior resistance to contaminants and moisture, effectively protecting electrical and mechanical components by forming a tight seal that secures conduits and cables, ensuring reliable operation in wet environments.
Implementation Method 1
the compression nut presses against the compression ring, the compression ring pressing against the sealing ring
Implementation Method 2
The nut first axial end 200 preferably has a nut first end inner surface 370 that is threaded. The connector first axial end 250 preferably includes a connector first end outer surface 350 that is threaded
Implementation Method 3
The nut second axial end 190 may have a nut second end outer surface 360 that is irregular to enhance gripping. The connector middle axial portion 240 may include a connector middle outer surface 380 that is irregular for easier gripping

AI summary
An exemplary connector assembly includes a connector body, a compression nut, a compression ring, and a sealing ring. A conduit may be inserted through the compression nut and the connector body. The compression ring may include a circumferential gap between two complementarily interfittable circumferential ends to allow it to compress, and the sealing ring may vary in diameter along its axial length. As the connector body screws into the compression nut, the compression nut presses against the compression ring, which in turn pushes the sealing ring against the connector body. The connector body may include a connector chamfer. The sealing ring pressing against the connector body, preferably against the connector chamfer, forms a seal between the conduit and the connector body. The seal resists contaminants such as dust and moisture. Compression of the compression ring around the conduit helps secure the conduit to the compression nut and the connector body.
