Split Body Snap Connector for Adjustable Junction Box Orientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing snap engagement electrical connectors with solid connector bodies cannot be adjusted in orientation relative to the electrical box, leading to loose initial fits and potential misalignment, especially in restricted spaces.
Innovation Solution
A tubular snap engagement electrical connector with a split connector body and a spring-biased snap ring featuring locking tangs, allowing for adjustable initial engagement and rotation within the knockout hole of the junction box, secured by a threaded fastener.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a solid connector body is used, then the connector forms a rigid connection with the junction box, but the connector cannot be adjusted in orientation relative to the box
Solution Approach 1:
The connector body is divided into two separable halves that can rotate relative to each other around a hinge axis. This segmentation allows the connector to be inserted in one orientation and then rotated to achieve the desired final orientation while maintaining a secure connection.
2Reliability
If a solid connector body is used, then the connection is firm, but the initial fit is loose and allows unintended orientation changes
Solution Approach 1:
The connector transitions from a static solid body to a dynamic structure where one half can rotate relative to the other. Initially, the connector allows movement for orientation adjustment, then locks into a firm fixed position when the halves are secured together.
3Adaptability or versatility
If the connector is made adjustable for rotation, then orientation can be changed, but the connection may become loose
Solution Approach 1:
The connector is designed so that the two halves are initially held together by a latch mechanism that allows rotation. After the desired orientation is achieved, the halves are permanently secured together, preventing future movement while maintaining the adjusted orientation.
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
Provides a firm yet adjustable connection that allows for easy insertion, rotation, and reorientation of the connector without unintended disengagement, ensuring secure electrical continuity and ease of installation in confined spaces.
Implementation Method 1
A tubular split snap ring including one or more locking tangs is disposed and held thereon on the leading end of the connector body by a spring bias
Implementation Method 2
The trailing body portion includes a threaded aperture and a threaded fastener therein

AI summary
A electrical connector for connecting conduit or cables to a junction box. The connector includes a tubular connector body with a longitudinal slot extending substantially along the length of the connector body and dividing the tubular connector body into an upper half and a lower half. A lateral slot extends through the upper half of the connector body at the leading end thereby hinging the upper half to the lower half at the trailing end of the connector. A tubular snap ring including one or more locking tangs is disposed and held thereon on the leading end of the connector body by a spring bias. The trailing body portion includes a threaded aperture and a threaded fastener therein. When inserted into a knockout in a junction box, the leading end of the snap engagement connector is held firmly but adjustably therein by engagement of the locking tangs with the panel, thereby allowing the orientation of the connector with respect to the box to be adjusted as desired. A conduit may then be inserted into the trailing end of the connector and secured therein by the fastener. Tightening of the fastener upon the conduit forces the upper half of the connector body away from the lower half and spreads the leading end of the connector body and the snap ring into tight engagement with the electrical panel.
