Abstract
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.
Claims17
A waterproof box structure, comprising:
- a composite plate comprising a chemical curing layer and a thermoplastic resin layer adhered to each other, the composite plate having a through hole, the through hole penetrating the chemical curing layer and the thermoplastic resin layer, wherein a diameter of the through hole in the thermoplastic resin layer is smaller than a diameter of the through hole in the chemical curing layer, such that a portion of the thermoplastic resin layer around the through hole is exposed by the chemical curing layer to form a flange;
- and
- a soft film covering the through hole, wherein an outer rim of the soft film covers the flange and is coupled to the flange.
A waterproof box structure manufacturing method, comprising the steps of:
- a. providing a composite plate, wherein the composite plate comprises a chemical curing layer and a thermoplastic resin layer adhered to each other;
- b. forming a through hole in the composite plate, wherein the through hole penetrates the chemical curing layer and the thermoplastic resin layer;
- c. removing a portion of the chemical curing layer from an inner rim of the through hole so as expose a portion of the thermoplastic resin layer around the through hole, wherein the exposed portion of the thermoplastic resin layer forms a flange;
- and
- d. forming a soft film covering the through hole such that an outer rim of the soft film covers the flange and is coupled to the flange.
