WATERPROOF BOX STRUCTURE

摘要

A waterproof box structure includes a composite plate and a soft film. The composite plate includes a chemical curing layer and a thermoplastic resin layer adhered and coupled to each other. The composite plate has a through hole. The through hole penetrates the chemical curing layer and the thermoplastic resin layer. The thermoplastic resin layer extends from the inner rim of the through hole and toward the center of the through hole to form a flange. The soft film hides the through hole. The outer rim of the soft film encloses the flange and is coupled to the flange.
