It is configured to be connected.

In addition, a lower case 5A and an upper case 5 are formed on the first board 1 and the fourth board 1C in a folded state, and the second board 1A and the first board 5 are formed in the folded state. Side walls 50 having predetermined heights are formed on the outer peripheries of the upper and lower cases 5 and 5A so that all the boards including the three boards 1B can be accommodated.

Along with the lower case 5A, a cradle 7 may be rotatably mounted to a terminal such as a personal digital assistant (PDA) and a mobile phone, and the cradle 7 may have an upper portion. It is configured to be supported while forming a predetermined angle of inclination by the support (6) rotatably formed on the side.

In addition, the cradle (7) is a common connector (4) so that when the terminal is mounted, it can be connected and connected to the first, second, third, fourth board (1) (1A) (1B) (1C) in a circuit Is integrally formed, and the connection port 4 is provided with a connection jack 4A so as to be connected to a connection jack of a computer, and the connection port 4 and the connection jack 4A are flexible passives. Is connected to and connected to a printed circuit board (not shown) in the first board 1.

And when folded as shown in Figure 2, the lower end of the upper case 5 of the fourth board (1C), the locking jaw 52 is formed so that the support (6) of the cradle 7 can be fixed by the locking and In addition, the through hole 51 is formed on the upper side of the upper case 5 so that the holder 7 is not interfered by the upper case 5. Here, reference numeral 8 denotes a first connection connector, and 8A is a second connection connector, which will be described in detail later.

The present invention configured as described above is used by mounting the terminal on the holder 7 in the unfolded state as shown in FIG. 1 or by plugging the jack for computer connection into the connection jack 4A formed in the connector 4.

In this state, when folding and carrying as shown in FIG. 2, first, the second board 1A is folded inward with respect to the hinge 2 on the first board 1 and the second board ( The third board 1B is folded outwards on 1A, and then folded again by folding the fourth board 1C on the third board 1B inward to overlap each other. The second and third boards 1A and 1B including the 1 and 4 boards 1 and 1C are accommodated inside the upper and lower cases 5 and 5A.

Then, the holder (7) is folded inward for fixing between the folded board, wherein the holder (7) is folded without interference by the through groove 51 formed in the upper case (5), again The support 6 connected to the holder 7 is fixed to the hanging jaw 52 formed at the lower case 5A, thereby completing a series of folding processes.

Figure 3 shows a connection structure between the board of the present invention, Figure 3a is a cross-sectional view showing the structure of the first connection connection portion of the present invention.

As shown in the drawing, the first connection connecting portion 8 has a first side wall A 81A and a second side wall A 82A on each end side of the first and second lower covers 81 and 82 of the boards which are mutually opposed to each other. The first side wall B, which is formed to protrude upward with each other, and is in contact with the first side wall A 81A and the second side wall A 82A on the upper side of the first and second lower covers 81 and 82. First and second upper covers 83 and 84 are formed so that 83A and the second side wall B 84A protrude downward on the end side. The first side wall A 81A and the second side wall are provided between the first upper and lower cover 83 and 81 and the printed circuit board 85 provided between the second upper and lower cover 84 and 82. It is configured to be interconnected by the flexible PCB 3 passing the upper side of A 82A.

3B is a cross-sectional view showing the structure of the second connection connector according to the present invention. As shown therein, the second connection connector 8A is formed at each end of the first and second upper covers 83 and 84 of the board which are mutually replaced. The first side wall B (83A) and the second side wall B (84A) are projected downward on the side facing each other, and the first, second upper cover (83, 84) on the lower side of the linear first, second Lower covers 81 and 82 are provided. The first side wall B 83A and the second side wall B are disposed between the first upper and lower cover 83 and 81 and the printed circuit board 85 provided between the second upper and lower covers 84 and 82. Interconnected by a flexible PCB 3 passing between 84A and the first and second lower covers 81 and 82.

The present invention configured as described above is configured for the circuit connection of the first, second, third, and fourth boards 1, 1A, 1B, 1C interconnected by the hinge 2, as shown in FIG. The first board 1 and the second board 1A are interconnected and connected by the first connection connector 8, and the second board 1A and the third board 1B are the second connection connector 8A. The third board 1B and the fourth board 1C are interconnected and connected by the first connection connector 8.

The mixing of the first connection connecting portion 8 and the second connection connecting portion 8A in this way is attributable to the rotational direction of each board around the hinge 2. That is, the second board 1A is folded inward, and the third board 1B is folded outward, and when it is not formed in such a structure, external force acts on the flexible PCB 3 so that the connection is broken or In order to prevent this, lengthening the length of the flexible PCB (3) is caused by the appearance of poor appearance by the protrusion thereof.

Figure 4 is a perspective view showing a coupling structure of the present invention, as shown in the support 6 of the present invention is formed of a wire (6A) bent in parallel in both directions in the same direction, the upper end of the cradle 7 Insertion holes 71 are formed on both sides so that the end side of the wire 6A can be inserted. In addition, a support jaw 72 is formed at an acute angle with respect to the vertical direction on the lower side holder 7 of the insertion hole 71 so that the wire 6A inserted into the insertion hole 71 of the holder 7 is caught. It is configured to support the cradle (7) at a predetermined inclination angle by the supporting force.

As described above, the present invention provides a personal portable terminal by allowing a user to fold and carry it in a pocket size while having the same character arrangement as a personal computer, and to access data such as a keyboard of a personal computer by connecting to a terminal in an unfolded state. And data input such as letters, numbers, symbols of the terminal such as a mobile phone can be made more quickly, thereby increasing the amount of data input within a limited time and the effect of making it easy to use.
