Design Evolution And Wiring Method Evolution Of Push-in Terminal Blocks

In current industrial control systems and power distribution devices, the mechanical structure of the push fit terminal exhibits a more compact design. The configuration between the spring element and the terminal body of the push fit terminal block connector is further optimized, allowing the wire to enter in a straight line during insertion. The spring then generates a reaction force to clamp the wire, and this direct contact design changes the dynamic process of wiring.

This structural change also manifests significantly in the details of wire connection. Compared to the previous method of securing wires with screws, the current push in connector block establishes contact with the wire through an internal spring, eliminating the need for additional steps and reducing inconsistencies in human operation.
