Description

  The present invention relates to cable storage technology applied to electrical products, and in particular, a flexible printed circuit board can be used in place of some conventional power connection lines, and a cable can be wound and stored in one direction (unidirectional). The present invention relates to a cable winding device including a switch.

In general, when electrical products are connected to each other or to computer equipment, signal connection or electrical connection is possible between electrical products or between electrical products and computer equipment via a single connection line. become.
There are two types of connection lines: direct connection to the electrical product or extension cords connected in series. Usually, it is not easy to store the cable after use, so use electrical products There is also a problem that the cables are cluttered when not.
Therefore, cable winders are now widely used to accommodate these connecting wires.
According to the cable winder, the connecting wires can be quickly stored, and after the storage is completed, the cable can be prevented from being broken or damaged due to pulling.
