In mobile terminals with enhanced waterproofness, the battery cover is often adhered to the housing using a waterproof double-sided tape. If the battery cover is adhered with the double-sided tape, the user of the portable terminal cannot replace the battery. On the other hand, if the battery cover is attached to the housing so that the battery cover can be removed by the user, and then the waterproofness of the mobile terminal is secured, the structure of the mobile terminal becomes complicated, and it is difficult to reduce the thickness of the mobile terminal. becomes.

An object of one aspect of the disclosed technology is to provide a portable terminal that can be thinned while ensuring waterproofness and allowing the user to replace the battery.

One aspect of the disclosed technology is exemplified by the following mobile terminal. The portable terminal includes a camera module having a lens, a battery, a metal plate member having a first opening in which the camera module is arranged, and a second opening in which the battery is arranged, a locking a battery lid having claws; a frame member provided on one surface of the battery lid and made of an elastic material; a front case adhered to the front surface of the plate member by a waterproof first double-sided tape; Prepare. The camera module is adhered to the plate member with a waterproof second double-faced tape in a state in which the photographing direction of the lens faces the rear side of the plate member. The battery cover is attached to the rear side of the second opening by engaging the locking claws with the plate member in a state in which the frame member is compressed by the plate member.

The configuration of the embodiment shown below is an example, and the disclosed technology is not limited to the configuration of the embodiment. A mobile terminal according to an embodiment has, for example, the following configuration. A mobile terminal according to the present embodiment includes a camera module having a lens, a battery, a first opening in which the camera module is arranged, and a second opening in which the battery is arranged. A metal plate member, a battery lid having an engaging claw, a frame member provided on one side of the battery lid and formed of an elastic material, and a waterproof first double-sided tape are used to hold the plate member together. a front case adhered to the front surface.

The camera module is adhered to the plate member with a waterproof second double-faced tape in a state in which the photographing direction of the lens faces the rear side of the plate member. The battery cover is attached to the rear side of the second opening by engaging the locking claws with the plate member in a state in which the frame member is compressed by the plate member.

In the portable terminal described above, the battery lid is not adhered to the plate member, but is attached to the plate member by means of locking claws. Therefore, the battery lid can be removed simply by releasing the engagement of the locking claw with the plate member, and the battery can be easily replaced. Here, when the battery lid is attached to the plate member, the frame member is in a compressed state, so that the frame member closes any gap that may occur between the battery lid and the plate member. Therefore, the mobile terminal can prevent water from entering the mobile terminal from between the battery cover and the plate member, and can maintain the waterproof performance of the mobile terminal. In addition, since the camera module and the battery can be arranged side by side on the plate member, the portable terminal can be easily made thinner.
