Generally, a mobile communication terminal is provided with an antenna for transmitting and receiving radio waves. Various types of antennas can be used, but a helical antenna having a helical antenna line for transmitting and receiving radio waves has been mainly used in the antenna body.

Since the helical antenna has a relatively large size, there is a problem against the trend of miniaturization and simplification of the mobile communication terminal.

In accordance with such a problem, a built-in antenna is mounted on a mobile communication terminal. Such a built-in antenna has a problem in that a high frequency band can not be processed in the process of pressing the metal thin film to the body.

In order to solve such a problem, an insert antenna in which a radiator made of a conductive film or a conductive metal is inserted into a metal mold and a radiator is embedded in the body through injection molding is often used.

As mobile communication terminals are miniaturized, a space that can be allocated for installing an insert antenna is rapidly decreasing.

Since the insert antenna is required to transmit and receive electromagnetic waves while maintaining electrical connection with the internal circuit of the wireless device, it is completely embedded in the limited space inside the wireless device. Can not.

Therefore, it is very important that the insert antenna maintain stable electrical connection with the internal circuit, including the main PCB, provided inside the wireless device.

The conventional insert antenna is assembled by mounting a C-clip as a coupling part on the main PCB and forming a contact point on the mounted clip.

The contact point of the insert antenna and the main PCB may cause instability of connection and thus the maximum performance of the antenna can not be realized.

Also, since the C-clip mounted on the main PCB increases the thickness of the wireless communication device, there is a problem in designing the shape of the wireless communication device.

The antenna frame 120 is made of an insulating material and has holes formed therein to insert the radiator 110 therein.

A molding rib (not shown) is formed in a mold for injection molding the radiator 110 and the antenna frame 120 so that a curvature or a bent shape can be formed in the radiator pattern 112.

The radiator pattern 112 forms a curved shape or a curved shape bent by the molding ribs formed in the mold.

The radiator 110 is inserted and fixed in the mold, and the flat radiator 110 can be naturally folded or curved by the forming ribs.

In the step of forming the insert injection molded product, the insert antenna 100 having the antenna frame 120 integrated with the radiator 110 inserted and fixed through a process of injecting a casting material into the inner space of the mold is formed. Casting materials can be applied to general PC, PC + Glass Fiber, PC / ABS and LCP.

After the radiator 110 and the antenna frame 120 are coupled by the insert injection method, the contact contact member 130 is joined to one side of the radiator 110.

2 and 3, a predetermined shape of the radiator pattern 112 is embedded in the upper surface of the antenna frame 120, and the radiator pattern 112 is exposed in the upper surface direction of the antenna frame 120 Holes 122 are formed at a certain depth from one side of the lower surface of the antenna frame 120 to partially expose the embedded radiator pattern 112 on the upper surface of the antenna frame 120.

The contact contact member 130 is inserted into the hole 122 formed at one side of the lower surface of the antenna frame 120 and is coupled to the partially exposed radiator pattern 112 through the hole 122.

The predetermined shape of the radiator pattern 112 is embedded in the side surface of the antenna frame 120 and the radiator pattern 112 is exposed in the lateral direction of the antenna frame 120. The contact contact member 130 is coupled to the exposed radiator pattern 112 in the lateral direction of the antenna frame 120.

The contact contact member 130 is inserted into the hole 122 formed at one side of the upper surface of the antenna frame 120 and is coupled to the partially exposed radiator pattern 112 through the hole 122. [

In this case, a corresponding connection portion such as the main PCB is seated in the hole 122 formed in the antenna frame 120, so that the connection is stably maintained.

4 to 6 are views showing the construction of a contact contact member according to an embodiment of the present invention.

The contact contact member 130 according to the embodiment of the present invention has a contact structure that allows the radiator 110 itself to contact the PCB.

The contact contact member 130 includes a fixed portion 140 fixed to the radiator 110, a movable portion 160 having a contact portion 161 serving as a contact point with the PCB, one end of the fixed portion 140, And an elastic part 150 for providing an elastic restoring force to the movable part 160. [

The contact contact member 130 has a structure to directly contact an internal circuit, such as a main PCB, provided inside the wired / wireless terminal or a metal body of the external housing (a ground portion of the wireless communication device).

The contact contact member 130 can be used as a metal such as stainless steel, beryllium copper, titanium copper, and phosphor bronze, and can be plated with nickel plating, gold plating, or the like.

The fixing part 140 includes a flat plate part 141 formed on a flat surface coupled to one surface of the radiator 110 and a flat plate part 141 bent and extended in the vertical direction from both side ends of the flat plate part 141, The left and right sides form the anti-slip portions 142 and 143 formed of '⊂' and '⊃' shapes.

The anti-slip portions 142 and 143 prevent the problem that the contact contact member 130 is lifted and damaged by enhancing the fixing force of the contact contact member 130 when the contact contact member 130 is electrically connected to the ground portion of the PCB or the wireless device.

The position fixing protrusions 144 and 145 protrude in a direction perpendicular to the direction in which the anti-slip portions 142 and 143 are formed and are positioned and fixed by being in contact with the radiator 110 at one end of the flat plate portion 141 .

The position fixing protrusions 144 and 145 can firmly fix the contact contact member 130 to the radiator 110 without disturbing the position of the contact contact member 130 when the radiator 110 is engaged.

The elastic portion 150 extends from one end of the fixing portion 140 to an upper portion and has a rounded shape, and the rear end of the movable portion 160 is connected to the upper end of the elastic portion 150.

The elastic part 150 elastically supports the entire movable part 160 and exerts an elastic force to always restore the contact part 161 to the initial position.

The movable part 160 is formed as a semi-circular shape upwardly connected to one end of the elastic part 150 and has a contact part 161 contacting the ground of the printed circuit board or the wireless communication device, And a plate 162 formed parallel to the plate portion 141 and spaced apart from the plate portion 141 by a predetermined distance.

The plate 162 is located in the space between the flat plate portion 141 and the anti-slip portions 142, 143.

The contact portion 161 contacts a terminal of another electronic component or an electronic device. When a terminal such as an electronic component touches an upper end of the contact portion 161 and applies a downward force, the movable portion 160 as a whole touches the elastic portion 150, The contact portion 161 descends.

The contact portion 161 exerts upward force due to the restoring force of the elastic portion 150 during the descent, so that the contact portion 161 exhibits a high contact force with the external terminal. Further, when the contact state of the external terminal is released, the contact portion 161 rises due to the restoring force of the elastic portion 150.

An upper surface of the contact portion 161 is provided with an embossing 163 for enhancing the contact force with the external terminal to be contacted to minimize the contact resistance and to transmit the signal stably.

The embodiments of the present invention described above are not implemented only by the apparatus and / or method, but may be implemented through a program for realizing functions corresponding to the configuration of the embodiment of the present invention, a recording medium on which the program is recorded And such an embodiment can be easily implemented by those skilled in the art from the description of the embodiments described above.
