Description

Slide-type mobile phone}

The present invention relates to a mobile phone, and more particularly to a mobile phone consisting of a main body portion and a folder portion, the folder portion is operated in a sliding manner and relates to a slide-type mobile phone opening and closing the main body portion.

In general, a mobile phone is a kind of advanced mobile communication means developed by a user so that the user can freely communicate wirelessly regardless of time and place. It has been evolved into flip type and folder type.

In addition, in recent years, a large LCD window is required to enjoy not only a simple call but also various multimedia functions with a mobile phone, and thus, a cellular phone having a small size and a light weight structure can be mounted on the mobile phone.

However, in order to use the folding mobile phone, there was an inconvenience in using the hinged fixed folder to open the main body, so to solve this problem, a slide that can be easily used while viewing the LCD window without having to open the folder in the related art. 3 is a perspective view of a conventional mobile phone.

As shown, the conventional slide-type mobile phone is provided with a plurality of input keys 11 on the front side, the microphone 12 is installed on the bottom and the battery unit 13 is mounted on the back and the main body 10, and It is provided in front of the main body portion 10 is provided with a large LCD window 21 on the front side and consists of a folder portion 20 is provided with a speaker 22 on the top.

At this time, the folder portion 20 is typically connected to the main PCB (not shown) and FPCB (not shown) built in the main body portion 10, the slide operation up and down by the normal transport means such as guide rails By opening and closing the front surface of the main body portion 10, the user can push up the folder to the upper side and use the mobile phone, and after use, it can be conveniently carried back.

In addition, the upper side of the main body 20 is provided with an antenna 30 for receiving radio waves, the conventional slide-type mobile phone as described above, because the antenna is protruding, interference caused by the antenna is caused to carry and store This inconvenience is not only an obstacle to the miniaturization and slimming of the mobile phone, but also serves as a spatial and functional limitation factor in the design of the mobile phone, making it difficult to apply various designs.

Accordingly, the present invention has been made to solve the above-mentioned conventional problems, the object is to provide a slide-type mobile phone that does not protrude the antenna while minimizing the appearance change of the mobile phone.

In order to achieve the above object, the present invention includes a main body in which the main PCB is built, a folder part provided to be slidable up and down on the front surface thereof, and an antenna for receiving a signal from the outside and transmitting the signal to the main PCB. In the slide-type mobile phone, the antenna is provided on the upper portion of the folder portion integrally formed so that the upper surface does not protrude to the upper surface of the folder portion, and the connection portion for connecting the antenna and the main PCB to transmit the received signal It is characterized by one.

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

1A and 1B show an embodiment of the present invention. FIG. 1A is a perspective view, FIG. 1B is a schematic cross-sectional view, and FIG. 2 is an operating state diagram according to FIG. 1B.

As shown, the present invention is provided with a plurality of input keys 11, the microphone 12 is installed on the lower portion of the main body portion 10 and the battery pack 13 is mounted on the back, and the main body portion 10 In the conventional slide-type mobile phone is provided in front of the large LCD window 21 is provided in the front and composed of a folder portion 20 is provided with a speaker 22 on the top, the antenna ( 30, but the upper surface is formed integrally so as not to protrude to the upper surface of the folder portion 20, the connecting portion 40 for transmitting the received signal by connecting the antenna 30 and the main PCB (14) Characterized in having a.

At this time, the folder portion 20 is connected to the main PCB 14 and the FPCB (not shown) built in the main body portion 10 as described above, and is moved up and down by the usual transport means such as guide rails. By being configured to open and close the front surface of the main body portion 10 while operating the slide, the user can use the mobile phone by pushing the folder upwards, and after use, it can be conveniently carried back.

Accordingly, since the antenna can be configured to not protrude while minimizing the appearance change of the mobile phone, unlike the conventional slide-type mobile phone having a protruding antenna, interference by the antenna can be prevented, so that the mobile phone can be easily carried and stored. In addition, it is possible to easily implement miniaturization and slimming.

In addition, the antenna 30 is configured such that one side thereof protrudes to the rear of the folder part 20, and a lower surface thereof covers the upper surface of the main body part 10 when the folder part descends.

In addition, the connection part 40 is provided on the upper part of the front surface of the main body part 10 and is connected to the PCB connection terminal 41 connected to the main PCB 14, and is provided on the upper part of the rear part of the folder part 20 and the folder part. The first connection terminal 42 which is in contact with the PCB connection terminal 41 when the lowering of the 20, and the first connection terminal 42 is provided in a line and the PCB when the folder portion 20 is raised The second connection terminal 43 is in contact with the connection terminal 41, and one side is connected to the antenna 30 and the connector 44 is sequentially connected to the first and second connection terminals (42, 43) do.

Accordingly, when the folder portion 20 is lowered and the front surface of the main body portion 10 is closed, the first connection terminal 42 connected to the antenna 30 side by the connector 44 is connected to the PCB connection terminal ( 41 is in contact with the antenna 30 to transmit the signal to the main PCB 14, when the folder 20 is raised to open the front surface of the main body portion 10 of the connector 44 The second connection terminal 43 connected to the lower end is brought into contact with the PCB connection terminal 41 to transmit the signal received by the antenna 30 to the main PCB 14.

As described above, the present invention is configured so that the antenna does not protrude while minimizing the appearance change in the slide-type mobile phone, unlike the prior art, it is easy to carry and store because it can prevent the interference by the antenna, miniaturization and slimming of the mobile phone Not only can be easily implemented, but has an effect that can be applied to a variety of designs.
