Sliding Outlet Bus Bar Connection Eliminates Wire Nuts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional outlet and switch boxes require the use of wire nuts to connect wires, resulting in a bulky and cumbersome setup, and pose challenges in connecting wires between junction boxes and outlets or switches.
Innovation Solution
The implementation of bus bars within the outlet or switch boxes allows for direct connection of three-conductor wires without wire nuts, and a sliding engagement mechanism between the outlet or switch and the junction box, eliminating the need for wires and wire nuts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wire nuts are used to connect wires between outlet boxes, then electrical connections can be made, but the wiring becomes bulky and cumbersome
Solution Approach 1:
The patent extracts and eliminates wire nuts from the wiring system by implementing a wireless connection mechanism. The outlet box is designed with integrated contact points that directly engage with corresponding contacts on the outlet device, removing the need for traditional wire nut connectors and significantly reducing wiring complexity.
Solution Approach 2:
The patent introduces an intermediary mechanical engagement structure between the outlet box and outlet device. This intermediary mechanism consists of aligned contact points and engagement features that facilitate direct electrical connection without requiring wire nuts, thereby simplifying the overall wiring process while maintaining connection reliability.
2Reliability
If wire nuts are used to connect multiple wires, then electrical connections are achieved, but the installation process becomes time-consuming and labor-intensive
Solution Approach 1:
The patent implements preliminary action by pre-configuring the outlet box with integrated contact points and engagement features before the wiring process. This pre-prepared structure allows for rapid connection of the outlet device without requiring time-consuming wire nut installation, significantly reducing installation time while ensuring reliable electrical connections.
Solution Approach 2:
The outlet box design incorporates self-aligning and self-securing features that automatically position and secure the electrical connections. The engagement mechanism includes features that guide the outlet device into proper alignment and automatically secure the connection, eliminating the need for manual wire nut installation and reducing installation time.
3Reliability
If traditional wiring with wire nuts is used, then electrical connections can be made, but the aesthetic appearance is compromised due to exposed wires and connectors
Solution Approach 1:
The patent applies the nesting principle by integrating the electrical connection mechanism within the outlet box structure itself. The contact points and engagement features are nested inside the outlet box, allowing wires to be concealed within the housing rather than exposed externally. This nested design maintains reliable electrical connections while improving aesthetic appearance by hiding the wiring components.
Solution Approach 2:
The patent extracts visible wire nuts and exposed wiring from the final assembly by implementing a wireless connection system. The electrical connections are made through integrated contact points that remain concealed within the outlet box structure, eliminating the need for visible wire nuts and improving the overall aesthetic appearance while maintaining connection reliability.

AI summary
A sliding outlet engages an outlet box having three bus bars, one for each of the hot, neutral, and ground wires of a three conductor wire. Extension portions of the sliding outlet achieve a friction fit to the bus bars so that the outlet is energized without the need for wire nuts.
