What is the insertion and extraction force of the terminal block in the lighting electrical ready board? Is it convenient for wiring and maintenance?

The African rural lighting electrical ready board is equipped with plug-in terminal blocks, which are suitable for local 1.5 mm ² and 2.5 mm ² lighting wiring scenarios, taking into account the narrow space inside the outdoor box and the manual operation conditions of on-site electricians. The peak pull-out force of a single pole terminal should not exceed 40 N, and the insertion force should not exceed 35 N. At the same time, the minimum pull-out force should not be less than 15 N to resist transportation and operational vibrations and prevent accidental loosening of the terminal.

This indicator is different from the wire clamping and holding tension specified in IEC 60947-7-1, and is specifically designed for the insertion and extraction operation force of on-site wiring, fault diagnosis, maintenance and replacement. The on-site tool conditions in rural Africa are limited, and excessive insertion and extraction force can easily cause cracking of terminal plastic shells, deformation of contacts, and rework of wiring; Reasonably control the insertion and extraction force of terminals inside the electrical ready board, achieve convenient manual insertion and extraction, reduce maintenance difficulty, improve the operation and maintenance efficiency of rural lighting projects in Africa, and achieve a balance between contact reliability, anti loosening performance, and user-friendly operation
