BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile communication terminal, and more particularly, to reduce the overall thickness of a slide-type mobile communication terminal equipped with a built-in antenna and to improve the communication signal transmission / reception performance of the built-in antenna. A slide module of a communication terminal.

In general, a mobile communication terminal is a wireless communication device that allows a user to carry a voice call with a specific person, and transmits a call message including a unique number of a receiver mobile communication terminal through a base station call channel to call a specific mobile communication terminal. After that, when a response is received from the mobile communication terminal, the system is configured to enable a call between the sender and the receiver.

In recent years, such mobile communication terminals have undergone many changes and developments in their functions and forms.In the functions of mobile communication terminals, only mobile phones can be used to play games, video on demand, electronic dictionary, and MP3. The latest mobile communication terminals capable of implementing the latest functions, such as players.

In addition, the mobile terminal has been developed from a bar-type mobile communication terminal to a flip-type, folder-type, and dual-foldable mobile terminal. In recent years, a slide-type mobile communication terminal in which a cover part of the mobile communication terminal is slidably moved is opened and closed. It is developed and released.

Herein, the structure of the slide-type mobile communication terminal that has been recently developed and released among the above-described mobile communication terminal will be described with reference to FIG. 1.

1 is a side cross-sectional view showing an internal configuration of a conventional mobile communication terminal.

As shown in FIG. 1, a conventional slide-type mobile communication terminal includes a display module 111 and a display module such as an LCD (Liquid Crystal Display; LCD) module for outputting an image signal. The cover 110 and the key input unit (not shown) provided with the printed circuit board 112 for processing the electrical signal of the (111) and the basic operation functions of the mobile communication terminal and to control the electrical signal of the display module 111 A main printed circuit board 121 having a plurality of chipsets (not shown) and a main body 120 having a built-in antenna module 200 are slide-coupled to form an appearance thereof.

In the slide type mobile communication terminal 100 having the above-described configuration, the cover 110 is slidably coupled to the upper portion of the main body 120, and the cover 110 is slidably moved with respect to the main body 120. Slide module 300 for slidingly coupling the cover 110 and the main body 120 between the cover 110 and the main body 120 so as to open and close the front surface of the main body 120. ) Is provided.

Here, the slide module 300 which slides the cover part 110 and the main body part 120 is a slider 320 and the cover part 110 fixed to be exposed on the front surface of the main body part 120. It is composed of a slide rail 310 mounted to be exposed to the outside through the slider groove 103 provided on the rear surface 102 of the) and slide coupled to the slider 320.

However, the coupling means for fixing the slide rail 310 constituting the slide module 300 provided in the above-described conventional mobile communication terminal 100 to the rear surface 102 of the cover portion 110 has a predetermined height. Since the screw 311 having the head portion 311a (refer to FIG. 5) formed is used, the height of the head portion 311a (refer to FIG. 5) is between the display module 111 and the slide rail 310. There is a problem that the space (D) is generated and the space (D) acts as an increase factor of the thickness of the cover portion as it is.

In addition, in the slide module 300 provided in the conventional slide-type mobile communication terminal 100 described above, the cover 110 is slid with respect to the main body 120 so that the main body 120 is moved.
