Description

A cable guiding apparatus and a portable computer provided with the apparatus

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cable guiding device and a portable computer provided with a cable guiding device, and more particularly, to a cable guiding device, a main body, and a display panel installed at a portion where bending motion occurs in a cable used in an electronic device. A portable computer electrically connected via an additional cable.

With the development of electronic technology, various types of computers are spreading and widely used. In particular, portable computers, such as laptop computers, notebook computers, and palmtop computers, are being widely used because they have mobility in place of desktop computers.

In general, as shown in FIG. 1, the portable computer 1 includes a body portion 2 in which various electronic elements are housed. In this case, the electronic elements include a keyboard, a central processing unit (CPU) of a computer, and a battery comprising a plurality of key switches and at least one printed circuit board having a matrix electrically connected to the key switches. Power supplies and suitable storage devices such as hard disks or floppy disks. The portable computer 1 also generally includes a display panel portion 4 which is coupled to be folded into the body portion 2 via some form of hinge structure. In this case, the display panel 4 serves as a cover that protects key elements of the keyboard exposed to the top of the main body 2 when the display panel 4 is covered on the top of the main body 2. do. When the display panel 4 is opened, the display panel 4 serves as a holder for accommodating the display unit seen by the computer user. The display unit may be formed of a display device such as a video monitor or a liquid crystal display.

On the other hand, various electronic elements of such portable computers need to be electrically connected. For example, a keyboard and a display are devices in which each other should work organically. Connections similar to this type of structure are generally referred to as flexible cables in a relatively flat configuration in the industry, and use some form of electrical cable, including cables that are sometimes referred to as flexible circuits. By doing so. Among the various electrical cables, in today's computer industry, the capacity can be increased particularly, and the use of flat cables in a flat form with various advantages is increasing.

As shown in FIG. 2, the conventional portable computer 10 in which the main body 12 and the display panel 14 are hingedly coupled to each other may electrically connect the main body 12 and the display panel 14 to each other. Cable 20 is used for this purpose.
