The Door Lock Of The African Rural Lighting Ready Board Should Be Firmly Connected To The Door Body And Box Body, And The Tensile Strength Of The Door Lock Should Not Be Less Than How Many Newtons?
Tensile strength standard for door locks of rural lighting ready boards in Africa
The lighting ready board for outdoor harsh working conditions in rural Africa has clear mechanical and rigid indicators for the firmness of the door lock, door body, and box connection structure. The overall tensile strength of the door lock should not be less than 500N. The universal acceptance standard for export complete Ready Board Box is based on this, and the recommended high anti-theft demand model number is ≥ 800N.
This value is suitable for the use environment in African rural areas with frequent sandstorms, children's casual touching, violent tearing of simple tools, and transportation bumps and collisions. It is formulated according to the low-voltage outdoor ready board and IEC 61439 matching door lock specifications. During testing, apply a continuous tensile force along the direction of the cabinet door opening for 1 minute. The door lock, lock tongue, and installation base must not break, detach, or permanently deform, and the cabinet door locking function must remain intact.
The assembly of the box and door lock requires reinforcement design: a reinforcing lining plate is added to the lock hole of the door body, and the lock buckle is welded/riveted to the load-bearing reinforcement position of the box body to prevent single point tearing under force. The basic zinc alloy tongue lock meets the minimum requirement of 500N; 304 stainless steel lock bodies are selected for high corrosion areas along the coast and mining areas, with a tensile strength of over 800N and a salt spray resistance of ≥ 500 hours, balancing strength and weather resistance.
If the tensile strength is less than 500N, external force pulling in rural areas can easily cause door locks to fall off, cabinet doors to open, and internal wiring to be exposed, posing risks of electric shock, short circuit, and fire. Each unit needs to undergo tensile testing for factory inspection, with an additional 100000 opening and closing durability tests for type testing. Only when the tensile strength meets the standard can it be exported to rural distribution projects in Africa.
