Description

FPC connection device for portable terminal {APPARATUS CONNECTING FPCB FOR PORTABLE TERMINAL}

The present invention relates to an FPC connection device of a portable terminal, and in particular, a portable terminal capable of minimizing the space required for the FPC to move when a camera rotatably installed in a predetermined angle range in the portable terminal is rotated. Of the FPC connection device.

In general, portable terminals such as cellular phones and PDAs have recently been equipped with a camera for storing and transmitting image information by capturing a person or an object. The rotating structure is configured to adjust the angle in a predetermined range so that the inside or the outside can be photographed.

In addition, the printed circuit board of the camera is connected to a printed circuit board of the main body by a signal connection line such as a flexible printed circuit board (FPCB) for transmitting signals, and adjusts the angle of the camera. As the length of the FPC is connected to be variable, and if the camera rotates, the space for the FPC is required.

In addition, when the barrel of the camera is coupled to the middle of the hinge part for opening and closing the folder in the folder type mobile phone terminal and rotates a predetermined angle based on the center line of the hinge part, the FPC is rolled up so that the camera can be rotated smoothly. In such a form, the space occupied by the FPC will change as the camera rotates, and sufficient space for the FPC to be deformed according to the rotation of the camera should be secured. However, there is a difficulty in minimizing the space while allowing the FPC to move sufficiently in a portable terminal that is gradually miniaturized.

The present invention was conceived in view of the conventional problems as described above, the camera barrel is coupled to the rotatable structure in the middle of the hinge portion for opening and closing the folder, the camera in the portable terminal connected to transmit a signal by FPC An object of the present invention is to provide an FPC connection device of a portable terminal to minimize the space required for the FPC to move when rotating.

In order to achieve the above object, the FPC connection device of a portable terminal according to the present invention has a camera body coupled to the portable terminal body so as to be rotatable in a predetermined angle range. It is configured so as to minimize the space for moving the FPC to move the FPC (preferably 2 to 5 times) to transfer the FPC.

Hereinafter, with reference to the accompanying drawings, the present invention will be described in detail as follows.

1 to 5 is a view of the FPC connection device of the portable terminal of the portable terminal according to the present invention, Figure 1 is a perspective view showing a portable terminal to which the present invention device is applied in the inside photographing state, Figure 2 the present invention device A perspective view of the portable terminal to which the portable terminal is applied from the outside photographing state is shown, respectively, and FIG. 3 is a partially cutaway perspective view of the portable terminal to which the present invention device is applied, and FIGS. 4 and 5 illustrate one embodiment of the present invention. Configuration and operation schematics are respectively shown.

The portable terminal illustrated in FIG. 2 is rotatably coupled to the main body 10 by the hinge part 30 to the main body 10, and the center of the hinge part 30 of the main body 10 of the portable terminal body 10 in the center axis direction. The barrel 50 to which the camera 40 is attached is coupled to rotate in a predetermined angle range.

In addition, the FPC 70 for transmitting a signal to the outside of the one side extension part 51 of the barrel part 50 is connected in a wound form, and to secure a space for the FPC 70 to move. In this case, the FPC 70 is preferably wound two or more times.

The FPC 70 has one end fixed to the barrel 50, and the other end has a connector 71 for connecting a signal with a circuit part of the terminal body 10, for example.

When the camera 40 faces inward as shown in FIG. 1, the portable terminal photographs the inward direction while the user looks at the screen, and when the camera 40 faces outward as shown in FIG. While looking at the image taken in the outward direction to store or transmit the image.

4 illustrates a form in which the FPC 70 is wound twice on the barrel portion 50 of the camera 40, for example. FIG. 5 rotates the barrel portion 50 by about 100 degrees in the state of FIG. 4. It showed form.

In addition, FIG. 6 shows a form in which the FPC 70 is wound once on the barrel portion 50 of the camera 40, for example. FIG. 7 shows the barrel portion 50 at about 100 degrees in the state of FIG. 5. It shows a rotated form.

As shown in FIG. 4 to FIG. 7, when the FPC 70 is wound twice, the FPC 70 is rotated when the barrel portion 50 is rotated as compared to when the FPC 70 is wound once. It can be seen that the space occupied by is reduced.

As described above, when the wound is used two or more times to rotate the camera 40, the space to move the FPC 70 may be reduced and the space to be secured for the movement of the FPC 70 may be minimized. .

For example, when comparing the space required for the movement of the FPC 70 when the barrel portion 50 of the camera 40 is rotated half a turn, that is, 180 degrees, the barrel portion 50 of the camera 40 is compared to the barrel portion 50 of the camera 40. When the FPC 70 is wound once, the radial size change of the circle on which the FPC 70 is wound becomes R as shown in FIG. 7, and when the FPC 70 is wound twice, the radius of the circle on which the FPC 70 is wound Directional change is 1 / 3R as shown in FIG. If it is wound three times, it is 1 / 5R. Therefore, as the FPC 70 is wound two or more times, the space required for the movement of the FPC 70 is reduced.

The FPC connection device of the portable terminal as described above is coupled to the rotatable structure of the camera barrel in the middle of the hinge portion for opening and closing the folder, the camera rotates in the portable terminal connected to transmit a signal by the FPC In this case, it is possible to minimize the space required for the FPC to move, thereby contributing to the miniaturization of the portable terminal.
