The front cover 101 may be mounted to the front case 103 constituting the inner case. The front cover 101 and the front case 103 may be attached by an adhesive or an adhesive member without using a separate fastening member or the like.

A portion of the front case 103 constituting the inner case may be configured to be exposed to the outside of the portable terminal. As shown in FIG. 2A, the edge of the front case 103 may be configured to be exposed to the outside to form an edge of the portable terminal.

A circuit board P may be provided between the front case 103 and the rear case 104 constituting the inner case. The front case 103 and the rear case 104 are fastened by a fastening member, and a circuit board P having a PCB shape can be accommodated therebetween.

The circuit board P may be installed at a position which does not overlap in the thickness direction of the battery mounting unit 104g and the portable terminal. This is to minimize the thickness of the portable terminal.

Accordingly, as shown in FIGS. 3 and 4, the circuit board P is disposed at an upper portion of a space between the front case and the rear case, and the battery mounting portion is provided at a lower rear surface of the rear case 104. Thus, the battery and the circuit board P may not overlap each other in the thickness direction.

The first user input unit 131 may be mounted between the front case 103 and the rear case 104, and the front cover 101 and the front case 103 may include the first user input unit 131. Mounting holes 103h and 151h for mounting may be formed, respectively.

The antenna module 200 may include an antenna carrier 210 having a housing shape and a pattern unit 220 provided on a surface of the antenna carrier 210.

The pattern unit 220 may be mounted on the surface of the antenna carrier 210 or may be provided by coating or printing on the surface of the antenna carrier 210.

The conventional method of mounting the antenna module 200 uses a method such as mounting on the circuit board, but there is a problem that increases the thickness of the portable terminal.

In addition, when the circuit board and the antenna module are directly connected to each other, the antenna module and the circuit board are disposed deep inside the main body of the portable terminal, and thus the reception sensitivity of the antenna may be reduced. Since the method of directly mounting the antenna module to the circuit board is for the electrical connection between the antenna module and the circuit board, if the electrical connection between the circuit board and the antenna module is replaced with a flexible circuit board, the circuit board and the antenna module are moved in the thickness direction of the portable terminal. The method of stacking and connecting directly can be avoided.

In addition, if the antenna module is directly mounted on a circuit board or the like, the number of labor for mounting the antenna module to the PCB circuit board or the like increases.

3 and 4, it is shown that the antenna carrier 210 of the antenna module 200 is detachably mounted to the lower bottom of the rear case 104 constituting the inner case.

Of course, a method of integrating the rear case 104 and the antenna carrier is also possible. However, when the failure rate of the antenna module is not small, waste of unnecessary material is caused.

The portable terminal according to the present invention includes an inner case, and the antenna module 200 is detachably configured to the inner case. Specifically, when the rear cover 102 is detachable from the portable terminal body due to the replacement of a battery or a card, the portable terminal should include at least one inner case, and the portable terminal according to the present invention is an antenna module. A method of detachably mounting 200 to an inner case is used.

3 and 4, the antenna module 200 is detachably mounted to the antenna mounting unit 104m provided under the rear case 104, and the antenna mounting unit 104m is detachably mounted. It may have a shape corresponding to the inner surface shape of the antenna carrier 210, when the antenna module 200 is fastened to the antenna mounting portion 104m, the antenna mounting portion 104m and the antenna carrier 210 may be combined. have.

Therefore, even when the antenna module 200 is mounted on the rear case 104 by overlapping, the increase in thickness due to the mounting of the antenna module 200 can be minimized.

As a method of mounting the antenna module 200 on the antenna mounting unit 104m, a fastening member may be used.

The fastening member may be a fastening bolt or the like. In the embodiment shown in FIGS. 3 and 4, an upper fastening member ub and a lower fastening member lb are shown.

The upper fastening member ub fastens the rear case 104 to the front case 103, and the lower fastening member lb fastens the antenna carrier 210 to the rear case 104. At the same time, the rear case 104 is fastened to the front case 103.

That is, since the lower fastening member lb fastens the antenna carrier 210, the rear case 104, and the front case 103 at the same time, the antenna module 200 is mounted on the rear case 104 which is an inner case. The separate fastening process can be omitted.

Specifically, the upper fastening member ub is fastened to the fastening holes 103h and 104h respectively formed at the top of the front case 103 and the rear case 104, and the lower fastening member lb is the antenna module. Fastening holes 220h and 103h formed in the antenna carrier 210, the lower part of the front case 103 and the antenna mounting part 104m of the rear case 104 while the 200 is mounted to the antenna mounting part. 104mh).

5 illustrates an assembly process of a portable terminal according to the present invention.

After the front cover 101, the display unit 151, the front case 103, the circuit board (P) and the rear case 104 are assembled in sequence, the upper fastening member (ub) The front case 103 and the rear case 104 are fastened, the antenna module 200 is seated on the antenna mounting part 104m, and the antenna module 200 is formed using the lower fastening member lb. ), The rear case 104 and the front case 103 may be fastened simultaneously to complete the assembly of the portable terminal body except for the rear cover 102.

The rear surface of the rear case 104 is provided with a battery mounting portion (104g) can be mounted to the battery as the power supply unit 190 in a state where the rear cover is removed.

In addition, at least one card mounting socket may be provided on the rear surface of the rear case 104. In the embodiment illustrated in FIG. 5, two card mounting sockets cs1 and cs2 are provided. Therefore, in the state in which the rear cover 102 is removed, the card can be mounted or removed together with the battery.

6 is a perspective view after the fastening process of the portable terminal shown in FIG.

The antenna module 200 is fastened together with the front case 103 and the rear case 104 which are inner cases, and a battery or various cards as the power supply unit 190 are connected to the battery mounting unit or the card mounting sockets cs1 and cs2. I can attach it.

Since the rear cover 102 is detachable from the rear case 104, the user can easily replace the card or battery.

When the antenna module 200 is broken or damaged, only the antenna module 200 may be separated from the rear case 104 and replaced, thereby minimizing maintenance costs.

While the present invention has been particularly shown and described with reference to preferred embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined in the following claims. . It is therefore to be understood that the modified embodiments are included in the technical scope of the present invention if they basically include elements of the claims of the present invention.

100: portable terminal 101: front cover
102: rear cover 103: front case
104: rear case 200: antenna module
210: antenna carrier 220: pattern portion
