Abstract

A mobile terminal comprises: a metallic frame; a first cover and a second cover coupled to a front surface and a rear surface of the metallic frame, respectively; and a first waterproof layer and a second waterproof layer formed between the first cover and the metallic frame, and between the second cover and the metallic frame, respectively, wherein the metallic frame includes: a base portion configured to support a display unit formed on the front surface of the metallic frame; and an edge portion formed along an outer periphery of the base portion so as to radiate heat generated from the base portion, and exposed to outside of the mobile terminal between the first cover and the second cover.

First claim

What is claimed is:

1. A mobile terminal, comprising:
a wireless communication unit including one or more components and configured to permit wireless communications between the mobile terminal and a wireless communication system or between the mobile terminal and a network within which the mobile terminal is located;
a window coupled to a display unit;
a first cover including a window mounting portion for mounting the window and the display unit inserting portion for inserting the display unit;
a metallic case including a base portion and an edge portion;
a non-metallic coupling, wherein the base portion of the metallic case is partitioned from the edge portion of the metallic case by the non-metallic coupling;
a first waterproof layer arranged between the window and a first side of the window mounting portion of the first cover;
a second waterproof layer arranged between a second side of the window mounting portion that is opposite to the first side of the window mounting portion of the first cover and the metallic case;
a main printed circuit board including an electronic device,
wherein the edge portion of the metallic case is configured to emit heat generated by the electronic device of the mobile terminal and includes a plurality of radiation portions configured to radiate wireless signals at different frequency bands,
wherein the base portion of the metallic case is configured to operate as a ground of the main printed circuit board or the plurality of radiation portions,
wherein the non-metallic coupling is formed as a single structure between the base portion of the metallic case and the edge portion of the metallic case, and
wherein a portion of the non-metallic coupling joins the edge portion of the metallic case with the base portion of the metallic case.

2. The mobile terminal of claim 1 , wherein the metallic case is provided with ribs disposed at a rear side of the metallic case, and the ribs divide a first region where the main printed circuit board is mounted from a second region where a battery is mounted,
wherein the non-metallic coupling is formed as a single structure at a front side and the rear side of the metallic case,
wherein the metallic case is provided with a hole penetrating between the front side and the rear side, and
wherein a portion of the non-metallic coupling passes through the hole and joins the non-metallic coupling on the front side with the non-metallic coupling on the rear side.

3. The mobile terminal of claim 1 , wherein the non-metallic coupling is formed as a single structure at a front side and a rear side of the metallic case, and
wherein the metallic case includes a hole penetrating between the front side of the metallic case and the rear side of the metallic case.

4. The mobile terminal of claim 1 , wherein the plurality of radiation portions include a first radiation portion and a second radiation portion, and the first radiation portion and the second radiation portion are respectively configured to operate at different frequency bands, and
wherein the first and second radiation portions form radiators together with first and second conductive patterns consecutive to the first and second radiation portions respectively, and the first and second conductive patterns are formed at a carrier disposed between the first cover and a second cover disposed at a rear side of the metallic case.

5. The mobile terminal of claim 1 , wherein the wireless communication unit is further configured to transceive signals corresponding to a voice service of the mobile terminal or a long term evolution (LTE) service of the mobile terminal.

6. The mobile terminal of claim 1 , wherein the metallic case is provided with ribs disposed at a rear side of the metallic case, and the ribs divide a first region where the main printed circuit board is mounted from a second region where a battery is mounted.

7. The mobile terminal of claim 6 , further comprising a sub printed circuit board disposed at a third region divided from the second region by the ribs,
wherein the metallic case is provided with a first through portion for passing a first flexible printed circuit board therethrough, and the first flexible printed circuit board is configured to connect the display unit to the sub printed circuit board.

8. The mobile terminal of claim 1 , wherein the metallic case is thermally coupled to the electronic device by a thermal member disposed between the electronic device and the metallic case.

9. The mobile terminal of claim 1 , wherein the first waterproof layer is disposed to fill a gap between the first cover and the metallic case.

10. A mobile terminal, comprising:
a wireless communication unit including one or more components and configured to permit wireless communications between the mobile terminal and a wireless communication system or between the mobile terminal and a network within which the mobile terminal is located;
a window coupled to a display unit;
a metallic case having a front side, a rear side, a top side, a bottom side, a base portion and an edge portion, and forming at least part of an appearance of a terminal body of the mobile terminal;
a non-metallic coupling, wherein the base portion of the metallic case is partitioned from the edge portion of the metallic case by the non-metallic coupling;
a cover for covering the rear side of the metallic case;
a first waterproof layer arranged between the window and the front side of the metallic case;
a second waterproof layer arranged between the rear side of the metallic case and the cover;
a main printed circuit board including an electronic device; and
a slit in the edge portion of the metallic case, wherein the slit is disposed at at least one of the top side of the metallic case or the bottom side of the metallic case,
wherein the edge portion of the metallic case is configured to emit heat generated by the electronic device of the mobile terminal and includes a plurality of radiation portions configured to radiate wireless signals at different frequency bands,
wherein the base portion of the metallic case is configured to operate as a ground of the main printed circuit board or the plurality of radiation portions,
wherein the non-metallic coupling is disposed in the slit and between the base portion of the metallic case and the edge portion of the metallic case, and
wherein a portion of the non-metallic coupling joins the edge portion of the metallic case with the base portion of the metallic case.

11. The mobile terminal of claim 10 , wherein the metallic case is provided with ribs disposed at the rear side of the metallic case, and the ribs divide a first region where the main printed circuit board is mounted from a second region where a battery is mounted,
wherein the non-metallic coupling is formed as a single structure at the front and rear sides of the metallic case,
