Prerequisites For Adjustable Pitch And Lead-out Angle Of Copper Terminal Blocks

For the design and selection of copper terminal block terminals, the pitch and exit angle settings must be based on the actual installation environment and wire layout to ensure that the structure and wiring space are compatible. For copper distribution block terminals, the pitch (i.e., the distance between the centers of adjacent terminals) should consider the wire diameter, insulation requirements, and assembly clearance. If the wire gauge is larger or a larger insulation gap is required, a larger pitch should be selected. If space is limited, it should be assessed whether a smaller pitch can be accommodated through reasonable arrangement and wiring, but contact reliability and mechanical strength must be guaranteed.

For the exit angle of copper terminal strip terminals, some installation spaces require wires to be led out from the side or in a specific direction. During the design phase, the interference relationship between the exit direction and the internal structure of the control cabinet/terminal box, and the positions of other components must be assessed. If the exit angle conflicts with the overall structure, the terminal block tilt angle should be adjusted or a rotatable/orientable terminal block structure should be selected to adapt to the space layout requirements.
