Solution Overview
Problem
Existing electrical connectors require significant time and effort to connect multiple wires to electrical devices, especially when large amounts of wire need to be managed within an electrical box, and existing solutions like twist-on wire connectors are cumbersome and difficult to use.
Innovation Solution
A push wire connector with a spring biasing member that allows for quick and secure termination of electrical wires without the need for tools, featuring a housing with conductive contact assemblies that receive both blade contacts and wires, ensuring electrical continuity by biasing the wires against contact members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional twist-on wire connectors are used to connect plug wires to building wires, then reliable electrical connection is achieved, but significant time and effort are required for each connection
Solution Approach 1:
The patent replaces the traditional mechanical twisting action with a spring-based mechanical system. The spring member automatically engages and secures the wire through elastic deformation, eliminating the need for manual twisting motions while maintaining secure electrical connection. This substitution of mechanical systems reduces connection time while preserving reliability.
2Reliability
If traditional wire connectors are used, then secure wire termination is achieved, but large amounts of wire must be inserted and managed in the electrical box
Solution Approach 1:
The patent extracts the wire insertion and securing function into a compact connector assembly that requires minimal wire length. The spring member and contact structure are designed to engage wires in a confined space, eliminating the need for long wire extensions that were previously required for traditional twist-on connectors. This extraction of function to a compact form reduces the quantity of wire material needed.
3Reliability
If multiple individual wire connections are made using traditional connectors, then each wire is securely terminated, but the overall device complexity and difficulty of installation increase
Solution Approach 1:
The patent merges multiple wire termination functions into a single integrated connector assembly. The housing contains multiple contact members and spring members that can simultaneously secure multiple wires through a unified structure. This consolidation reduces installation complexity by replacing multiple separate connector operations with a single integrated component installation.
4Reliability
If traditional wire connectors are used, then electrical continuity is established, but the process requires significant manual effort and is difficult to operate
Solution Approach 1:
The patent implements a self-service mechanism where the spring member automatically engages and secures the wire upon insertion. The elastic properties of the spring provide automatic clamping force without requiring manual tightening or twisting actions. This self-service feature eliminates the need for complex manual operations while maintaining reliable electrical continuity, significantly improving ease of operation.
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
Enables rapid and tool-free connection of multiple electrical wires to an electrical device, providing secure and efficient electrical continuity, reducing the complexity of wire management within electrical boxes.
Implementation Method 1
A spring member disposed in the housing is connected to the contact member. The spring member has a first opening through which a wire is passed to electrically engage the contact member. The spring member biases the inserted wire against the second end of the contact member.
Data Source
AI summary
An electrical connector includes a housing and a conductive contact assembly disposed in the housing. A first contact member of the contact assembly receives a blade contact of an electrical device. A second contact member receives an electrical wire through a push-in connection. The electrical connector is receivable by an aperture in a rear surface of the electrical device.
