High-Voltage Spring Clip for Threadless Busbar Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-voltage electrical connections in three-phase electric machines often require time-consuming threaded connections with clinch nuts and screws, which can be cumbersome and inefficient for assembly and disassembly.
Innovation Solution
A spring clip with corrugated and ribbed gripping members, joined by a trapezoidal member, allows for a threadless connection that secures busbars with a resilient friction grip, facilitating easy assembly and disassembly using a tool to separate the gripping members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If threaded connections with clinch nuts and screws are used, then connection reliability under vibration is improved, but assembly time and device complexity increase
Solution Approach 1:
The patent extracts and eliminates the threaded connection components (clinch nuts and screws) from the electrical connection system, replacing them with a spring-loaded gripping mechanism that achieves reliable vibration-resistant connections without requiring threading operations
Solution Approach 2:
The spring clip mechanism is designed to automatically maintain electrical connections through its resilient spring force, which self-adjusts to keep conductive members securely engaged without requiring additional fastening operations or components
2Reliability
If threaded connections with clinch nuts and screws are used, then connection reliability under vibration is improved, but device complexity increases
Solution Approach 1:
The patent merges multiple functions into a single integrated spring clip component that simultaneously provides mechanical clamping force, electrical contact, and vibration resistance, eliminating the need for separate clinch nuts, washers, and screws
Solution Approach 2:
The invention removes the complex threaded connection subsystem (clinch nuts, washers, screws) and replaces it with a simplified spring-loaded gripping mechanism that achieves the same reliability through elastic deformation and friction grip
3Stability of the object's composition
If threaded connections are used, then connection stability is improved, but ease of operation deteriorates
Solution Approach 1:
The patent employs a dynamic spring-loaded mechanism that automatically adapts to connection forces and vibrations, maintaining stable electrical contact through continuous elastic adjustment rather than rigid threaded fastening
Solution Approach 2:
The spring clip mechanism self-regulates the connection pressure through its resilient properties, automatically maintaining optimal contact force without requiring manual adjustment or additional fastening operations
Applied Scientific Principles

AI summary
A spring clip for securing busbars of an electrical connector. The spring clip may include gripping members which exert pressure on the busbars, preventing the busbars from uncoupling. The spring clip provides a threadless means for joining the busbars, which is desirable for ease-of-assembly when coupling and uncoupling the electrical connector. The spring clip may include raised members for separating apart the gripping members using an external tool. The gripping members may include corrugated portions which engage with the busbars. The gripping members may also include rib members which may stiffen the gripping members.
