How Do Push-in Terminal Blocks Reduce The Workload Of Assembly Operations?

In electrical cabinet assembly workshops, traditional screw-type terminal wiring requires workers to repeatedly use screwdrivers, performing hundreds of tightening actions daily. push in terminal block wire connector replaces threaded fastening with a spring clamping mechanism, simplifying the wiring process to a single insertion and fundamentally changing the way the work is done. This structural innovation is based on both ergonomic and contact mechanics considerations.

push connector block has an internal pre-compression spring sheet. The spring automatically opens when the wire is inserted and springs back to clamp it in place. The entire process typically requires a thrust of 8-12 Newtons, equivalent to the force of holding a pen. In contrast, with screw-type terminals, workers need to apply 15-20 Newtons of torque to achieve the specified crimping force and rotate the screwdriver 6-8 times. Biomechanical tests show that the rotational motion places 3.2 times the load on the wrist joint and forearm muscles compared to a linear push-in motion.

In distribution cabinet assembly scenarios, a single cabinet contains an average of 120 wiring points. Using a push fit connector block to complete all wiring takes approximately 18 minutes, while screw terminals require more than 45 minutes. While the time was shortened, the worker's muscle fatigue index decreased by 60%, and surface electromyography signal analysis showed that the activation intensity of the wrist flexor muscles was significantly reduced.
