On the other hand, any of the signal lines 205 of the flexible circuit board 200 connected to the connectors C1 and C2 should be connected to each connector 1: 1.

Therefore, when one of the signal lines 205 is branched to two or more signal lines 206 and 207 in regions (A, B, and H, baseline of the bent portion) where there is a risk of occurrence of disconnection, (E.g., 207), even if breakage occurs, the remaining connectors can be connected to each connector 1: 1 through the remaining branch lines (e.g., 206).

Further, as described above, the two or more branch signal lines 206 and 207 may be electrically connected through a plurality of bridges (not shown) whose both ends are electrically connected to the respective signal lines, (Bridge) described with reference to FIG. 8 and the embodiment (branch) described with reference to FIG. 8 may be combined.

9 is a conceptual view showing still another embodiment of a flexible circuit board 200 constituting a mobile terminal according to the present invention.

9, the flexible circuit board 200 positioned at the boundary between the first body 104 and the second body 101 is provided with three signal lines 221 222, and 223 may be provided.

The three signal lines 221, 222 and 223 may be electrically connected in a part of the flexible printed circuit board 200 located at the boundary between the first body 104 and the second body 101. By having such a structure, even if a signal line (for example, 221) is disconnected, the electrical connection relationship can be continuously maintained through the remaining signal lines (for example, 222 or 223).

As described above, a part of the area of the flexible printed circuit board 200 has two or more bent portions A and B, and three signal lines 221, 222 and 223 disposed in the bent portions A and B Can be electrically connected.

When the second body 101 is mounted on the first body 104 as a folder type, a hinge 107 is provided at a boundary between the first body 104 and the second body 101, The circuit board 200 includes a first region 201 disposed inside the hinge 107 and a second region 201 extending from both ends of the first region 201 at a predetermined angle, 151 and the second region 202 and the third region 203, respectively.

Here, the flexible circuit board 200 may be electrically connected to three signal lines 221 to 223 located in a boundary region A between the first region 201 and the third region 202.

For convenience, three signal lines are referred to as a first signal line 221, a second signal line 222 and a third signal line 223, respectively.

The three signal lines 210 and 211 may be electrically connected through a plurality of bridges 224 to 227 electrically connected to two signal lines 221 and 222, And a pair of bridges 224 and 225, 226 and 227 connecting the adjacent two signal lines may be respectively provided on both sides with respect to the center line H of the bent portions A and B . The pair of bridges 224 and 225, 226 and 227 are bent at the bent portions A and B because the possibility of disconnection near the center line H of the bent portions A and B is high, And are spaced apart from each other by a predetermined distance with respect to a center line H of each of the first and second electrodes.

The bridge connecting the first signal line 221 and the second signal line 222 for convenience is referred to as a first bridge 224 and a second bridge 225 and the second signal line 222 and the third signal line 222, The bridge connecting the second bridge 223 is referred to as a third bridge 226 and a fourth bridge 227.

As described above, one signal line of the flexible circuit board 200 connected to each connector C1 and C2 must be connected to each connector 1: 1. For example, the first signal line 221 and the second signal line 221 2 signal lines 222 are connected to the pair of bridges 224 and 225 at the regions where the breakage is likely to occur (A, B, and the H line of the bent portion of the bent portion), the first signal line 221 is broken The first signal line 221, the first bridge 224, the second signal line 222, the second bridge 225, and the first signal line 221, The line can be connected 1: 1 with each connector.

Accordingly, since the first to third signal lines 221 to 223 perform the same function, when the disconnection occurs in the second signal line 222, The transferred data may be transferred to the first signal line 224 through the first bridge 224 or to the third signal line 223 through the third bridge 226.

It is needless to say that the embodiment (branch) described with reference to FIG. 8 and the embodiment (bridge) connecting FIG. 9 may be used in combination.
