The present invention relates to a radio switch provided in a mobile phone, and more particularly, to minimize the abnormality of the radio switch due to the fall of the mobile phone and to increase the space utilization of the rear case to the maximum as well as the use of the radio switch It relates to a radio switch of the mobile phone to improve the durability.

In general, a mobile phone is a mobile communication means developed to allow a user to freely communicate wirelessly regardless of time and place, and according to a user's preference, a flip type and a clamshell type have a gradually smaller volume from a bulky radio type in the early stage of development. As the terminal has a structure having such a structure and the like, in recent years, a mobile phone having various functions equipped with an auxiliary device such as a digital camera as well as a wireless internet connection is available.

The structure of the foldable mobile phone 100 which is commonly used among the mobile phones usefully described above will be described schematically with reference to FIG. 5, which transmits a keypad 102 and a voice for inputting various information on the upper surface. The receiver 104 is provided, and an antenna 105 for receiving a radio wave is installed at one side of the upper end, and a main circuit board (not shown) for controlling an electrical signal is installed therein, and a rechargeable battery pack is provided at the rear side thereof. A rear case 110 provided with 106; The front case 120 is provided with an LCD window 112 for displaying visual information such as various characters and figures on a surface facing the rear case, and a talker 114 for outputting a received voice.

In the above, a volume switch (not shown) is installed on one side of the rear case.

In the conventional clamshell-type mobile phone configured as described above, information input through the keypad is displayed on the LCD window through the main circuit board and simultaneously transmitted to the outside through the antenna, and the information received through the antenna passes through the main circuit board. In addition to operating the device, it was displayed on the LCD window, making the phone useful for its needs.

In addition, according to the trend of the times, the function that can be used for the purpose of the radio (PUSH TO TALK) by synchronizing the frequency in advance between users so that they can communicate between mobile phones without going through the base station where more additional functions are required. It was easily used in areas such as mountainous areas where communication is not possible or where there is no base station to make a call, or where call sensitivity is low.

In addition, in the case of a mobile phone having a radio function as described above, a radio switch connected to the main circuit board built into the side of the rear case is arbitrarily installed and used, the conventional radio switch used in the mobile phone is A conventional tap switch directly connected to the main circuit board installed inside the rear case was used.

As a result, the size of the mobile phone gradually decreases, which causes a problem of securing a space for installing the tap switch into a narrow space of the rear case.

In addition, when the drop test after the production of the mobile phone or when the user drops the mobile phone in use, the crack occurs between the main circuit board and the tap switch, or due to the lifting of the parts to lose the function as a radio use.

In addition, since the tap switch is always pressed and used for the use of the radio, the durability of the tap switch is also very weak.

Accordingly, the present invention has been made to solve the conventional problems as described above, the purpose is to minimize the abnormality of the switch for the radio due to the fall of the mobile phone and at the same time to maximize the space utilization of the rear case and the radio It is to improve the durability according to the use of the switch, and to support the metal dome switch unit with a greater supporting force.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a schematic cross-sectional side view showing the main part of the present invention, FIG. 2 is a schematic cross-sectional view of the main part showing the back side according to FIG. 1, and FIG. 3 is a schematic main enlarged cross-sectional view of the present invention.

As shown, the LCD circuit board (LCD FPCB) 121 built into the front case 120 is integrally connected to the main circuit board 101 embedded in the conventional rear case 110 and the rear case ( In the mobile phone 100 having a switch for the radio on the side of 110,

According to the present invention, a terminal switch 12 is mounted on a radio switch of the transceiver installed on the side of the case 110. The main PCB 101 and the LCD PC 121 are integrally connected with each other. The terminal frame 15 formed by insert molding a well-known switch frame 14 including an integrally bent and formed on the terminal pattern 12 of the switch frame 14 by pressing a button described later on the terminal pattern ( A metal dome switch unit 10 formed by stacking a conventional metal dome 16 connected to 12;

A support bracket (20) having a support piece (24) formed on the main circuit board (101) so that one end is inserted into and fixed to the main circuit board (101), and the other end supports the rear surface of the bent terminal portion (15);

Installed on the rear case 110 is shown to consist of a button 30 is formed with a pressing projection 32 for pressing the metal dome 16.

Radio switch of the present invention configured as described above is configured by applying the structure of the known metal dome switch, the conditions that can make the most of the utilization space in the rear case, that is, the main circuit board and the built-in The internal part of the rear case is secured to the maximum by forming the metal dome switch part loaded with the metal dome integrally formed by integrally bending the terminal part with the terminal pattern and the switch frame on the part where the LCD PC embedded in the front case is integrally connected. To maximize space utilization.

In addition, since the terminal portion of the metal dome switch unit is integrally formed with the LCD FPC, it is also provided with a condition that no crack or part is lifted due to the impact of the drop of the mobile phone.

In addition, as the metal dome of the metal dome switch unit is pressed by the pressing protrusion of the button as the button is pressed to be used for the radio use, the terminal pattern of the terminal may be connected to the terminal pattern to smoothly use the radio as well as the The pressing force generated by the button has a condition excellent in durability by the corresponding force of the support bracket for supporting the terminal portion.

Therefore, it is possible to maximize the utilization of the interior space of the rear case of the mobile phone and to minimize the failure rate of the radio switch installed on the side of the rear case and to provide improved durability according to the use of the radio switch.

4 is a main view showing another embodiment of the present invention.

In the above configuration as shown, to have a greater bearing capacity of the metal dome switch portion according to frequent use for the radio,

The other side of the support bracket 20 shows that the support bracket 20 is supported by a reinforcing piece 40 integrally formed from a rib meat which is usually formed on the inner surface of the rear case.

Accordingly, even when the terminal portion of the metal dome switch portion is frequently used by a button, the support bracket for supporting the terminal portion is frequently supported from both sides by a reinforcing piece integrally formed from the ribs of the main circuit board and the rear case. It will have sufficient responsiveness to the pressing force according to the use and will also have the conditions that can be used easily without a long period of time.

As described above, the present invention is configured by applying a metal dome switch structure of the radio switch installed in the rear case side of the mobile phone, it is possible to maximize the utilization of the internal space of the rear case, as well as the failure rate due to the fall of the mobile phone In addition to minimizing and providing improved durability to frequent use of the radio switch, the support bracket for supporting the terminal part of the metal dome switch part is supported by both the main circuit board and the reinforcing piece so that the radio switch can be It also has the effect of having a minimum failure rate even during frequent use and long service life.
