FIG.

An antenna pattern forming housing having improved waterproof performance according to the present invention is a housing 10 constituting an outer appearance of a mobile communication apparatus 100. The housing includes an antenna pattern portion 12 formed on a front surface of the housing 10, A through hole 14 is formed in the housing 10 to electrically connect the antenna pattern portion 12 and the terminal pattern portion 20 to the terminal pattern portion 20 formed on the back surface of the terminal pattern portion 10, And the through-hole insertion member 16 is inserted into the through-hole 14.

The housing 10 is a housing constituting a part of the entire mobile communication apparatus housing 100. An antenna pattern 12 is formed on a front surface of the housing 10 and a terminal pattern 20 is formed on a back surface of the housing.

A through hole 14 for passing current between the antenna pattern 12 and the terminal pattern 20 is formed through the housing 10. A terminal protrusion 22 is formed at an end of the terminal pattern 20, Can be formed.

Here, the antenna pattern 12 and the terminal pattern portion 20 are formed by a plating or printing process.

In general, an electroplating apparatus is a device in which a plated body to be plated is connected to a negative electrode (-), a metal plate made of a plated film is connected to a positive electrode (+), and a plated body The metal ions are put on the surface of the object to be plated, thereby plating the object to be plated.

In the process of forming the antenna pattern on the surface of the housing 10, first, the surface of the housing 10 is irradiated with a laser beam so that a portion to be formed with the antenna pattern is cut to a predetermined depth.

At this time, in order to increase the adhesion of the plating metal and the surface of the housing 10 in the antenna pattern portion formed by plating, the surface of the antenna pattern portion formed at an engraved depth by laser light is roughly formed.

Thus, the surface area of the portion where the pattern is formed is increased to increase the adhesion to the plating metal.

Alternatively, the antenna pattern 12 may be formed by a printing method of printing an antenna pattern on the surface of the housing 10 using conductive ink.

A terminal pattern portion 20 for connecting a terminal portion of a PCB to be disposed in the mobile communication device is disposed on the back surface of the housing 10 and a terminal pattern portion 20 for connecting the terminal pattern portion 20 and the antenna pattern (14) is formed for energization between the electrodes (12).

The diameter d of the through hole 14 may be in the range of 0.3 mm to 0.8 mm. The diameter d of the through-hole 14 may be in the range of 0.3 mm to 0.8 mm.

When the diameter d of the through-hole 14 is less than 0.3 mm, it becomes very difficult to manufacture the metal mold and insert the through-hole inserting member 16 into the through-hole 14.

When the diameter d of the through hole 14 is greater than 0.8 mm, a conductive metal layer is formed in the through hole 14, and when the through hole insertion member 16 is inserted, Foreign matter such as moisture or dust can be intruded through the gap between the insertion member 16 and the through hole 14. [

5, the through holes 14 are formed in the upper portion 14-1 of the through hole, whereas the through holes 14 are formed in the upper portion 14-1 of the through hole, And the width is formed to be larger than the width of the lower portion 14-2.

Thus, when the through-hole 14 is formed by an injection process using a mold, the mold portion formed with a small width or a diameter d (0.3 to 0.8 mm) is minimized to prevent breakage of the mold do.

The through-hole insertion member 16 is not easily detached from the through-hole 14 when the through-hole insertion member 16 is inserted into the through-hole 14.

The part of the housing 10 on which the through hole 14 is formed is placed in the plating tank so that the plating metal layer 12 or a conductive metal is printed on the antenna pattern 12 and the through hole 14 to form a metal layer.

At this time, in order to prevent foreign substances such as moisture or dust from being introduced into the mobile communication apparatus through the through hole 14, a through hole insertion member 16 is inserted into the through hole 14 do.

As the material of the through-hole inserting member 16, a synthetic resin material such as silicone or a paint or the like may be used.

At this time, preferably, the synthetic resin material such as silicone or the coating material is filled in the through-hole 14 in a state of the liquid phase and then cured by time elapse through contact with air or irradiation with ultraviolet rays, (14).

Meanwhile, the inner housing 30 may be disposed at a portion where the housing 10 (outer housing) is disposed, and the inner through hole 32 may be formed in the inner housing 30.

In addition, the PCB 50 included in the mobile communication device may be disposed inside the inner housing 30.

The internal housing 30 is provided with an internal through hole 32 for disposing a terminal portion 52 provided on the PCB 50, The terminal portion 52 is connected to the terminal pattern portion 20 or the terminal projecting portion 22 in a state where the terminal portion 52 is disposed.

In this case, in order to more reliably prevent foreign matter such as water flowing into the through-hole 14 from intruding into the mobile communication device, the center C1 of the through-hole 14 is formed in the inner through- And the center C2 of the base portion 32 is disposed at a position shifted on the side end face.

Thus, foreign matter such as moisture penetrated into the through-hole 14 can be prevented from intruding into the internal through-hole 32 immediately.

That is, in a state where the through holes 14 formed in the outer housing 10 and the inner through holes 32 formed in the inner housing 30 are disposed at positions separated from each other in cross section, the outer housing 10 The inner surface of the inner housing 30 and the outer surface of the inner housing 30 are brought into close contact with each other via the terminal pattern portion 20 so that the water intruded through the through hole 14 is directed toward the inner through hole 32 So that it can not be introduced.

As described above, the antenna pattern on the surface of the housing 10 irradiates a laser beam to cut the portion to be formed with the antenna pattern to a predetermined depth.

At this time, in order to increase the adhesion of the plating metal and the surface of the housing 10 in the antenna pattern portion formed by plating, the surface of the antenna pattern portion formed at an engraved depth by laser light is roughly formed.

Alternatively, an antenna pattern may be formed by applying a conductive ink to the antenna pattern portion by a printing method.

The terminal pattern portion 20 is formed on the back surface of the housing 10 to be connected to the terminal portion 52 of the PCB of the mobile communication device, A plating layer may be formed directly on the back surface of the housing 10 or in a state where the portion where the terminal pattern portion 20 is formed is cut away using laser light.

Alternatively, the terminal pattern portion 20 may be formed by directly printing the conductive ink.

The diameter of the through hole 14 may be in the range of 0.3 mm to 0.8 mm. The diameter of the through hole 14 may be in the range of 0.3 mm to 0.8 mm when the housing 10 is formed by an injection process using a metal mold. .

The housing 10 in which the through hole 14 is formed is placed in the plating tank and the antenna pattern portion and the portion of the through hole 14 The plating metal layer 12 is formed.

Alternatively, a conductive ink is applied to portions of the antenna pattern 12 and portions of the through holes 14 by a printing method to form a conductive metal layer.

Thereafter, in order to prevent foreign matter such as moisture or dust from entering the inside of the mobile communication apparatus through the through hole 14, a synthetic resin material such as silicone or a through material of a paint material The hole insertion member 16 is inserted and arranged.
