Abstract

Provided is an electronic device case. The electronic device case includes a radiator including an antenna pattern portion transmitting or receiving a signal, and a connection terminal portion transmitting the signal to or receiving the signal from a circuit board of an electronic device, and an electronic device case frame manufactured by subjecting the radiator to injection-molding, supporting the radiator and forming an exterior of the electronic device. The antenna pattern portion includes an exposed portion exposed on the outermost edge of the electronic device case frame.

Claims

1. An electronic device case comprising:

a radiator including an antenna pattern portion transmitting or receiving a signal, and a connection terminal portion transmitting the signal to or receiving the signal from a circuit board of an electronic device; and

an electronic device case frame manufactured by subjecting the radiator to injection-molding, supporting the radiator and forming an exterior of the electronic device,

wherein the antenna pattern portion includes an exposed portion exposed on the outermost edge of the electronic device case frame.

2. The electronic device case of claim 1, wherein the exposed portion is formed in part of the antenna pattern portion.

3. The electronic device case of claim 1, wherein the exposed portion has at least one insertion hole serving to fix the radiator to a mold for injection-molding the electronic device case frame.

4. The electronic device case of claim 1, wherein the exposed portion is formed by bending the antenna pattern portion toward the outermost edge of the electronic device case frame in a stepped manner.

5. The electronic device case of claim 1, wherein the radiator includes a connection portion connecting the antenna pattern portion with the connection terminal portion as a part of the radiator,

wherein the connection portion is formed such that the antenna pattern portion is arranged on one side of the electronic device case frame, and the connection terminal portion is arranged on the other side of the electronic device case frame, which is opposite to the one side thereof.

6. The electronic device case of claim 1, wherein the connection terminal portion is in contact with and is supported by a radiator support portion protruding from the other side of the electronic device case frame, which is opposite to the one side on which the antenna pattern portion is arranged.

7. The electronic device case of claim 1, wherein the electronic device case frame includes a coating layer on the outermost surface thereof to protect the exposed portion.

8. The electronic device case of claim 1, further comprising a cover contacting one surface of the electronic device case frame and forming an exterior of a body.

9. A mobile communications terminal comprising:

an electronic device case including an electronic device case frame manufactured by subjecting a radiator including an antenna pattern portion and a connection terminal portion to injection-molding, wherein the antenna pattern portion includes an exposed portion exposed on the outermost edge of the electronic device case frame; and

a circuit board connected to the connection terminal portion and receiving a signal from or transmitting a signal to the radiator.

10. The mobile communications terminal of claim 9, wherein the exposed portion is formed in part of the antenna pattern portion.

11. The mobile communications terminal of claim 9, wherein the exposed portion has at least one insertion hole serving to fix the radiator to a mold for injection-molding the electronic device case frame.

12. The mobile communications terminal of claim 9, wherein the exposed portion is formed by bending the antenna pattern portion toward the outermost edge of the electronic device case frame in a stepped manner.

13. The mobile communications terminal of claim 9, wherein the radiator includes a connection portion connecting the antenna pattern portion with the connection terminal portion as a part of the radiator,

wherein the connection portion is formed such that the antenna pattern portion is arranged on one side of the electronic device case frame, and the connection terminal portion is arranged on the other side of the electronic device case frame, which is opposite to the one side thereof.

14. The mobile communications terminal of claim 9, wherein the connection terminal portion is in contact with and is supported by a radiator support portion protruding from the other side of the electronic device case frame, which is opposite to the one side on which the antenna pattern portion is arranged.

15. The mobile communications terminal of claim 9, wherein the electronic device case frame includes a coating layer on the outermost surface thereof to protect the exposed portion.

16. The mobile communications terminal of claim 9, further comprising a cover contacting one surface of the electronic device case frame and forming an exterior of a body.

17. A mold for manufacturing an electronic device case, the mold comprising:

an upper mold and a lower mold receiving a radiator including an antenna pattern portion receiving and transmitting a signal, a connection terminal portion contacting a circuit board of an electronic device, and a connection portion allowing the antenna pattern portion and the connection terminal portion to be arranged in difference planes; and

a resin material injection portion formed in the upper mold, the lower mold or the upper and lower molds so that, when the upper and lower molds are joined, a resin material is injected into an internal space between the upper and lower molds through the resin material injection portion and is applied to the radiator to thereby form an electronic device case,

wherein the upper mold comes into contact with the radiator so that the antenna pattern portion is exposed on the outermost edge of the electronic device case, and the electronic device case including the radiator is formed in the internal space.

18. The mold of claim 17, wherein the antenna pattern portion includes at least one insertion hole,

wherein the upper mold includes a coupling pin inserted into the insertion hole to fix the radiator in the internal space.

19. The mold of claim 17, wherein the coupling pin is formed of a magnet.

20. The mold of claim 17, wherein the internal space between the upper and lower molds receives the connection terminal portion, and a radiator support portion is formed in the internal space to support the connection terminal portion.
