Abstract

A mobile terminal comprises: a case that has an insertion hole formed on a side surface thereof; a metal beam that includes a side metal covering the side surface of the case, and a connection bridge penetrating the insertion hole and extending towards the inside of the case from the side metal; a fixing device that is inserted into a fixing hole formed on the connection bridge so as to be fastened to the case; and a waterproof packing that is interposed between the side surface of the case and the side metal, and that has an opening part through which the connection bridge passes. As a result, water cannot get inside the terminal, and malfunctioning due to water permeation can be prevented thereby.

First claim

The invention claimed is:

1. A mobile terminal comprising:
a case comprising a side surface that defines an insertion hole;
a metal beam including a side metal that covers the side surface of the case and a connection bridge that extends from the side metal into the case, that is inserted through the insertion hole of the case, and that passes through the side surface of the case;
a fastener that is inserted into a fixing hole defined in the connection bridge and that is fastened to the case; and
a waterproof packing that is interposed between the side surface of the case and the side metal and that defines an opening through which the connection bridge passes.

2. The mobile terminal of claim 1 , further comprising:
a connection substrate positioned inside the case and having one end in contact with the connection bridge.

3. The mobile terminal of claim 2 , wherein the connection substrate comprises an opening through which the fastener passes, the connection substrate being interposed between the case and the connection bridge.

4. The mobile terminal of claim 2 , further comprising:
a main board mounted inside the case;
a first connecting clip formed on a first surface of the main board and in contact with an opposite end of the connection substrate;
a second connection clip formed on a second surface of the main board and electrically connected to the first connection clip; and
an antenna in contact with the second connection clip.

5. The mobile terminal of claim 4 , wherein the connection bridge comprises:
a first connection bridge connected to one side of the antenna; and
a second connection bridge spaced apart from the first connection bridge and connected to a second portion of the antenna.

6. The mobile terminal of claim 2 , further comprising:
a ground electrically connected to the connection bridge.

7. The mobile terminal of claim 1 , wherein the fastener comprises a fixing pin having a diameter corresponding to the fix hole and a head larger than the diameter of the fixing pin.

8. The mobile terminal of claim 1 , wherein the side metal faces the side surface of the case and is disposed outward of the side surface of the case.

9. The mobile terminal of claim 1 , wherein an extension length of the connection bridge from the side metal is greater than a thickness of a side wall of the case that defines the side surface of the case.

10. The mobile terminal of claim 1 , wherein the case comprises:
a front case comprising a first surface configured to seat a display unit, a second surface opposite to the first surface, and a side wall that connects the first surface to the second surface and that defines the side surface of the case; and
a rear case coupled to the second surface of the front case, and
wherein the connection bridge passes through the side wall of the front case.

11. The mobile terminal of claim 1 , wherein the connection bridge has a flat shape, and a width of the insertion hole is greater than a height of the insertion hole.

12. The mobile terminal of claim 11 , wherein the opening of the waterproof packing has a shape corresponding to the flat shape of the connection bridge.

13. A mobile terminal comprising:
a case that defines an insertion hole in a side surface thereof;
a metal beam comprising a side metal that covers the side surface of the case and a connection bridge that extends from the side metal into the case through the insertion hole;
a fastener that is inserted into a fixing hole defined in the connection bridge and that is fastened to the case;
a waterproof packing that is interposed between the side surface of the case and the side metal and that defines an opening through which the connection bridge passes;
an auxiliary bridge positioned on an outer surface of the case; and
an auxiliary fastener fastened to the case by passing through the auxiliary bridge.

14. The mobile terminal of claim 13 , wherein the case comprises:
a front case allowing a display unit to be seated on one surface thereof; and
a rear case coupled to a rear surface of the front case to define an internal space,
wherein the fastener passing through the connection bridge is coupled on an opposite surface of the front case, and
wherein the auxiliary fastener passing through the auxiliary bridge is coupled on the one surface of the front case.

15. The mobile terminal of claim 14 , wherein an end portion of the auxiliary fastener is in the same plane as the one surface of the front case.
