AI Technical Summary
In the existing coil wiring structure, the clamping force at the plug end is unstable, causing the terminal block to tilt, resulting in poor assembly stability and reliability. At the same time, the winding end structure is complex and inconvenient for assembly.
Using elastic elements as coil connectors, combined with a helical spring structure and limit block design, provides stable clamping force and uniform contact pressure, prevents the connector from tipping over, and simplifies the winding process.
It improves the assembly stability and reliability of the terminal block, simplifies the assembly process, and enhances the stability and reliability of electrical connections.
