Description

Terminal {Terminal}

The present invention relates to a terminal with reinforced side strength.

Terminals may be divided into mobile / portable terminals and stationary terminals according to their mobility. The mobile terminal may be classified into a handheld terminal and a vehicle mount terminal according to whether a user can directly carry it.

As the functions are diversified, the terminal is implemented in the form of a multimedia player having a complex function such as taking a picture or video, playing a music or video file, playing a game, or receiving a broadcast. In addition, in addition to the complex functions as described above, there has been a recent trend toward miniaturization, slimness, and weight reduction of terminals. In particular, in the case of a portable terminal, development of a compact, slim, and lightweight terminal in consideration of portability may be an important factor in securing a product's competitiveness.

In general, the terminal includes a frame in which the control circuit of the terminal is placed, a front case positioned in front of the frame, and a rear case positioned behind the frame. The battery is inserted into a battery insertion unit provided in the rear case of the terminal, and a battery case is further provided at the rear of the rear case to cover the battery so as not to be exposed to the outside. The front case, the rear case and the frame may be coupled by a fastening member.

Recently, in order to miniaturize the terminal, there is a trend to decrease the thickness and width of the battery. In the case of increasing the width of the battery as described above, it is difficult to place the fastening member on both sides of the battery insert outside because of insufficient space. Therefore, in the conventional terminal, the battery insertion unit is eccentrically positioned in the rear case, one side of the rear case and the front case is coupled by a fastening member, and the other side is coupled by a hook method. However, the other side of the rear case and the front case coupled by the hook method has a disadvantage that the bending occurs by the external force. In particular, the other side of the rear case and the front case may be bent to the outside of the terminal by the force pushed by the battery when the battery is detached from the battery insertion unit. Due to the bending, there is a problem in that the hook coupling is loosened and the reliability of the terminal coupling may be lowered.

The present invention is to provide a terminal made of a rigid and easy assembly of the rear case, the frame and the front case.

Terminal according to an embodiment of the present invention comprises a front case to form a front appearance; A rear case coupled to the front case and having an insertion portion formed on an inner side thereof; And a frame positioned between the front case and the rear case and having a protrusion formed therein, wherein the protrusion is inserted into and supported by the insertion unit.

According to an embodiment of the present invention, the front case, the rear case and the frame through the coupling structure can be implemented a terminal that prevents the front case and rear case coupling portion is bent.

5 is a view showing a frame according to an embodiment of the present invention, Figure 6 is a view of the S2 of FIG.

5 and 6, the frame 150 is provided with a protrusion 151 that can be inserted into the insertion part 125. The protrusion 151 may be provided at a position corresponding to the position where the insertion portion 125 is formed. The protrusion 151 may be injection molded integrally with the frame 150.

FIG. 7 is a cross-sectional view taken along line AA ′ of FIG. 1.

Referring to FIG. 7, the frame 150 and the rear case 120 are seated on the front case 110, and the battery case 130 is seated on the rear case 120.

In detail, the front case 110 is provided with a seating portion 111 which may be in contact with the first rib 121 and the protrusion 124 of the rear case 120. The first rib 121 may be seated on an upper surface of the seating part 111, and the protrusion 124 may contact the inner surface of the seating part 111. The protrusion 124 is located on the inner surface of the seating part 111, so that the rear case 111 does not push to the outside (F1 direction) even when the rear case 120 receives a force in the F1 direction.

The frame 150 is located between the front case 110 and the rear case 120. One end of the frame 150 is provided with a protrusion 151 that can be inserted into the insertion portion 125 formed by the first rib 121 and the second rib 123 of the rear case 120. When the protrusion 151 is inserted into the insertion part 125, the second rib 123 is prevented from moving in the F2 direction by the protrusion 151 even when the rear case 120 receives the force in the F2 direction. not moving. Thus, the rear case 120 and the frame 150 may be coupled, and the rear case 120 may be prevented from being pushed or bent in the F2 direction by the force in the F2 direction.

As described above, through the coupling between the front frame 110 and the rear frame 120, and the coupling between the frame 150 and the rear frame 120, the rear frame 120 has the first end outside (F1, F2) The rear frame 120 and the front frame 110 may be firmly fixed so as not to push or bend in the outward direction even when the force is applied in the direction.

Meanwhile, the connection part 122 connecting the first rib 121 and the second rib 123 to the rear case 120 may be formed to correspond to the inner shape of the battery case 130. When the battery case 130 is mounted on the rear case 120, the connection part 122 is in contact with the inside of the battery case 130. As a result, the battery case 130 may be more stably seated on the rear case 120.
