Casing structure for electronic devices
View Patent ↗An aspect provides a method, including: fixing a laminated panel, which has been cut into a predetermined shape, to a mold, said laminated panel having an expanded layer disposed between layers made of a conductive resin; injection of molding non-conducting resin into the mold in which the laminated panel has been fixed; wherein a non-conductive region and a conductive region are joined to form a bottom surface of a display casing, said display casing having an inner and outer surface; and wherein an antenna mounting space is formed in the non-conductive region. Other aspects are described and claimed.
1. A method, comprising:
fixing a laminated panel, which has been cut into a predetermined shape, to a mold, said laminated panel having an expanded layer disposed between layers made of a conductive resin;
injection of molding non-conducting resin into the mold in which the laminated panel has been fixed;
wherein a non-conductive region and a conductive region are joined to form a bottom surface of a display casing, said display casing having an inner and outer surface; and
wherein an antenna mounting space is formed in the non-conductive region.
2. The method according to claim 1 , wherein the conductive resin comprises a carbon fiber reinforced plastic.
3. The method according to claim 1 , wherein the non-conductive resin comprises a glass fiber reinforced plastic.
4. The method according to claim 1 , wherein the conductive and non-conductive regions are butt jointed to form the bottom surface area.
5. The method according to claim 1 , wherein the conductive and non-conductive regions are lap jointed to form the bottom surface area.
6. The method according to claim 1 , wherein the non-conductive resin partially comes into the expanded layer causing them to become firmly joined to each other.
7. The method according to claim 1 , wherein the thickness of the antenna mounting space is made to be smaller than the thickness of the joint portions and the conductive resin region.
8. The method according to claim 1 , wherein the conductive region includes a camera region for mounting a camera.
9. The method according to claim 1 , wherein the outer surface of the display casing is coated with paint so that the joint portions are invisible from the outside.
10. A method comprising:
fixing a laminated panel, which has been cut into a predetermined shape, to a mold, said laminated panel having an expanded layer disposed between layers made of carbon fiber reinforced plastic; and
injection molding glass fiber reinforced plastic into the mold in which the laminated panel has been fixed;
wherein a glass fiber reinforced plastic region and a carbon fiber reinforced plastic region are butt joined to form a bottom surface of a display casing; and
wherein an antenna mounting space is formed in the glass fiber reinforced plastic region.
