Abstract

A mobile terminal includes a display unit, a front case configured to be combined with the display unit using a front side of the front case, a main board configured to be combined with a rear side of the front case, a rear case configured to be combined with a rear side of the main board, a boss in which a internal screw thread formed on both a left side and a right side of the front case and the internal screw thread heading a rear side is formed, a connection hole formed on a position corresponding to the internal screw thread of the rear case, a screw configured to be connected with the internal screw thread in a manner of passing through the connection hole, a boss bump configured to be positioned at an outer circumstance of the boss and a boss accommodation part configured to be formed on both a left side and a right side of the main board and correspond to a shape of the boss and a shape of the boss bump. It is able to reduce thickness of the mobile terminal by omitting a frame. And, it is able to prevent the case from making a gap in a horizontal direction via a stable connection structure. Moreover, it is also able to prevent the front case and the rear case from being separated from each other via the stable connection structure.

Claims

1. A mobile terminal comprising:

a display unit;

a front case having an opening formed there through, wherein the front case is configured to permit the display unit to be viewed through the opening from a front side of the front case;

a main board configured to be combined with a rear side of the front case;

a rear case configured to be combined with a rear side of the main board;

a boss projecting inward from an edge portion of the front case, the boss having a rear-facing opening formed therein with an internal screw thread on an inner surface of the rear-facing opening, and the rear case including a connection hole formed to align with the rear-facing opening in the boss;

a screw configured to pass through the connection hole and engage the internal screw thread; and

a boss bump,

wherein the main board includes a boss accommodation part that abuts the side surface of the boss, the boss accommodation part having a shape that is configured to accommodate the shape of the boss and the boss bump.

2. The mobile terminal of claim 1, wherein the boss accommodation part comprises a boss groove, and wherein the boss bump projects laterally from a side surface of the boss and into the boss groove, the boss groove having a recessed shape configured to accommodate the shape of the boss bump.

3. The mobile terminal of claim 2, wherein the boss bump projects diagonally from the side surface of the boss relative to a horizontal line perpendicular to the edge portion of the front case.

4. The mobile terminal of claim 2, wherein the boss comprises a plurality of boss bumps projecting from the side surface of the boss.

5. The mobile terminal of claim 2, wherein the boss bump has a rear surface and the boss has a rear surface, and wherein the rear surface of the boss is further rearward than the rear surface of the boss bump.

6. The mobile terminal of claim 1, wherein the boss accommodation part comprises a bump hole formed there through, the bump hole having a shape configured to receive and accommodate the shape of the boss bump which projects rearward from the rear surface of the front case through the bump hole.

7. The mobile terminal of claim 1, wherein the boss is configured such that a rear surface of the boss projects further in a rearward direction than a rear surface of the main board and a rear surface of the boss bump.

8. The mobile terminal of claim 1, wherein the boss bump has a curved or polygonal shape.

9. The mobile terminal of claim 1, wherein the front case comprises a plurality of bosses projecting inward from an edge portion thereof, and at least one connection hook projecting inward from the edge portion of the front case and contacting the rear surface of the main board;

and wherein the rear case comprises at least one connection groove, each connection groove aligning with and configured to receive a corresponding connection hook.

10. The mobile terminal of claim 1, wherein the main board is configured to contact a rear side of the display unit via an opening formed at the center of the front case.
