Screw Connection Design Logic For Push-in Terminals

push in type terminal block employs an engineered fixing device to control the contact interface between the screw and the conductor within a specific pressure range. This structure allows technicians to apply radial force to the wire using the screw during wiring, firmly embedding the wire into the metal conductor inside push in terminal block wire connector while maintaining the stability and continuity of the electrical path.

This connection method takes into full consideration the fit between the metal conductor and the push connector block conductive component. When the screw is screwed into the push fit connector block, the metal plate or clip moves along its helical axis, filling the tiny gaps between the wire and the conductor, promoting a tight fit of the electrical contact surfaces.

On the other hand, unlike structures that rely entirely on spring force, push fit terminal, combined with the screw, provides adjustable mechanical feedback during wire positioning.
