Snap-Ring Quick Connect Fitting for Tight Electrical Box Knockouts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The connection of male threaded connectors or raceways to an electrical box is a laborious and time-consuming task, especially when multiple connections are required due to limited clearance between knockouts.
Innovation Solution
A quick connect fitting with a one-piece tubular body featuring a snap ring with locking and grounding tangs, allowing for a snap-in connection to the electrical box knockout, reducing the need for multiple locknuts and facilitating easier installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional locknuts are used to secure male threaded connectors to electrical box knockouts, then reliable mechanical connection is achieved, but installation time and labor cost increase significantly
Solution Approach 1:
The patent combines multiple functions (mechanical connection, grounding, and securing) into a single integrated fitting assembly that replaces the traditional two-locknut system. The fitting includes an integral body with threaded engagement features and grounding elements, allowing one-component installation that achieves both reliable connection and time savings.
Solution Approach 2:
The fitting is designed as a multi-functional component that simultaneously provides mechanical attachment to the knockout, threaded connection for the male connector, and electrical grounding path. This universal design eliminates the need for separate grounding wires or additional fastening elements.
2Adaptability or versatility
If multiple male threaded connectors are connected to one panel with minimal clearance between knockouts, then all connection points are served, but installation complexity and time increase substantially
Solution Approach 1:
The fitting is designed as a modular, self-contained unit that can be independently installed at each knockout location. The segmented design allows installers to work on one connection at a time without interference from adjacent connectors, even in tightly spaced configurations.
Solution Approach 2:
The fitting incorporates dynamic installation features including threaded engagement mechanisms that allow for adjustment and alignment during installation. The modular nature enables flexible positioning and orientation to accommodate varying knockout spacings and connector types.

AI summary
A quick connect fitting for connecting any male threaded connector or raceway to an electrical box. The quick connect fitting includes a one-piece tubular body having a leading end for connection to a knockout and a trailing end for accepting any male threaded connector or raceway. A seat on the leading end of the tubular body includes a snap ring thereon for quick connection to the knockout of an electrical box. One or more locking tangs on the snap ring facilitate connection of the leading end of the fitting of the to the electrical box. One or more grounding tangs on the quick connect fitting enhance grounding of the fitting to the electrical box to establish continuity between the connector body and any male threaded pipe or conduit secured into the female threads on the trailing end of the fitting.
