Abstract

The mobile terminal includes a first part, a second part, a connection structure, and a flexible circuit bar. A signal is transmitted between the first part and the second part through the flexible circuit board. The flexible circuit board includes a first end and a second end. The first end is electrically connected to the first part, and the second end is electrically connected to the second part. The flexible circuit board passes through the connection structure, and a part of the flexible circuit board in the connection structure maintains a regular bending structure.

First claim

1 .- 18 . (canceled)
