However, in the conventional folding type terminal as described above, the extension part is responsible for the electrical connection function between the LCD flexible circuit and the main board, and the extension part is not good in assembling and AS, and has a rather weak disadvantage in folder opening and closing quality. There is this. That is, during the terminal assembly process, the configuration in which the extension part is connected to the connector of the main body main board via the hinge device is not easy, which causes a decrease in productivity.

In particular, the portable terminal has a high risk of dropping when carrying, and often a folder is broken when it is dropped, and then the extension part is often broken. In this case, there is a disadvantage in that the entire LCD flexible circuit needs to be replaced.

In addition, since the extension part is integrally formed with the LCD flexible circuit, there is a problem in that a tensile force is generated to some extent during opening and closing of the folder, thereby causing disconnection.

Accordingly, an object of the present invention is to provide a board-to-board connection device that is convenient for the AS when the portable terminal is dropped and damaged.

Still another object of the present invention is to provide a board-to-board connection device in pursuit of improving folder opening and closing life.

Another object of the present invention is to provide a connection device between boards with improved assembly.

Still another object of the present invention is to provide a board-to-board connection device which minimizes the influence of the tensile force when opening and closing the folder.

In order to achieve the above objects, the present invention provides a folder-type terminal comprising a main body, a folder, and a hinge device connecting the main body and a folder.
