Abstract

A housing, a method for manufacturing the housing, and a mobile terminal having the housing include a substrate including a metal area, a slot defined in the metal area of the substrate and penetrating through the substrate, and a filling layer received in the slot and including an insulating layer and a paint layer on the insulating layer.

First claim

What is claimed is:

1. A housing comprising:
a substrate comprising a metal area;
a slot defined in the metal area of the substrate and penetrating through the substrate; and
a filling layer received in the slot and comprising an insulating layer and a paint layer on the insulating layer;
wherein the paint layer comprises:
a base paint layer formed on the insulating layer;
a colored paint layer formed on the base paint layer, wherein the colored paint layer is configured to determine the color of the paint layer; and
a top paint layer formed on the colored paint layer, wherein the top layer is configured to protect the colored paint layer.

2. The housing of claim 1 , wherein the paint layer has the same width as the insulating layer.

3. The housing of claim 1 , wherein the paint layer has a width larger than the insulating layer.

4. The housing of claim 3 , wherein the width the paint layer is 0.02 mm-0.06 mm larger than that of the insulating layer.

5. The housing of claim 1 , wherein the paint layer has a thickness of 0.2 mm-0.3 mm.

6. The housing of claim 1 , wherein the colored paint layer has substantially the same color as the outer surface of the substrate, to cause an outer surface of the paint layer has the same color as an outer surface of the substrate.

7. The housing of claim 1 , wherein an outer surface of the paint layer is flush with an outer surface of the substrate.

8. The housing of claim 6 , wherein the top paint layer is further configured to render the color of the paint layer richer.

9. The housing of claim 8 , wherein the base paint layer, the colored paint layer, and the top paint layer each comprises at least one sub-layer.

10. The housing of claim 9 , wherein the base paint layer, the colored paint layer, and the top paint layer each comprises different numbers of sub-layers.

11. A mobile terminal comprising a housing and an antenna accommodated in the housing, wherein the housing comprises:
a substrate comprising a metal area;
a slot defined in the metal area of the substrate and penetrating through the substrate; and
a filling layer received in the slot and comprising an insulating layer and a paint layer on the insulating layer, the filling layer being configured to provide a passage for signals of the antenna;
wherein the paint layer comprises:
a base paint layer formed on the insulating layer;
a colored paint layer formed on the base paint layer, wherein the colored paint layer is configured to determine the color of the paint layer; and
a top paint layer formed on the colored paint layer, wherein the top layer is configured to protect the colored paint layer.

12. The mobile terminal of claim 11 , wherein an outer surface of the paint layer has the same color as an outer surface of the substrate, and is flush with the outer surface of the substrate.
