Description

[0001] MOBILE TERMINAL [0002]

The present invention relates to a mobile terminal.

A terminal can be divided into a mobile terminal (mobile / portable terminal) and a stationary terminal according to whether the terminal can be moved. The mobile terminal can be divided into a handheld terminal and a vehicle mounted terminal according to whether the user can directly carry the mobile terminal.

The functions of mobile terminals are diversified. For example, there are data and voice communication, photographing and video shooting through a camera, voice recording, music file playback through a speaker system, and outputting an image or video on a display unit. Some terminals are equipped with an electronic game play function or a multimedia player function. In particular, modern mobile terminals can receive multicast signals that provide visual content such as broadcast and video or television programs.

Such a terminal has various functions, for example, in the form of a multimedia device having multiple functions such as photographing and photographing of a moving picture, reproduction of a music or video file, reception of a game and broadcasting, etc. .

In order to support and enhance the functionality of such terminals, it may be considered to improve the structural and / or software parts of the terminal.

On the other hand, the mobile terminal frequently falls on the floor due to the characteristics of being held in a user's hand or stored in a bag or the like. Therefore, the impact caused by the drop is transmitted to the electronic parts disposed inside the mobile terminal, and the parts that are impacted are likely to be broken.

According to the conventional mobile terminal impact prevention structure, a cover is placed on a case of a mobile terminal, or a shock pad is provided between a case and an electronic part to prevent an impact transmitted to an electronic part disposed inside the mobile terminal.

However, these methods have a problem that the esthetics of the mobile terminal are lowered and the manufacturing cost of the mobile terminal is increased. Particularly, in the case of the buffer pads, the internal electronic parts can be more impacted when they are not attached properly in the mobile terminal, which limits the reliability of the product.

Disclosure of Invention Technical Problem [8] The present invention has been proposed in order to solve the above-mentioned problems, and it is an object of the present invention to provide a mobile terminal which can safely protect a mobile terminal from an external impact.

According to an aspect of the present invention, there is provided a mobile communication terminal comprising: a terminal body; A display unit disposed on a front surface of the terminal body and outputting an image or an image; A battery disposed on one side of a rear surface of the terminal main body and in contact with a power source element formed on the terminal main body; A board unit disposed on another side of the rear surface of the terminal main body and on which various electronic components are mounted; A rear cover covering the rear surface of the terminal body; And a flexible substrate provided between the terminal body and the rear cover for electrically connecting the substrate unit to the battery and the display unit, the flexible substrate comprising: a body; And a bending portion that is extended from one side of the body and is bent so that one side of the body is in contact with the body.

The mobile terminal according to the present invention has the following effects.

First, a space for shock absorption is formed through the bent portion of the flexible substrate, so that the terminal can be safely protected even if the terminal is dropped.

Secondly, the number of components required for shock absorption can be reduced, and the manufacturing process is simplified, and the manufacturing cost is reduced.
