If the wire connected to the earphone and plug occurs due to the external structure, it is not appropriate to store the wire connected to the earphone when it is not used in various electronic products, so put it in the user's pocket, bag, handbag, etc. The wires are entangled with each other and inherent in use, and they have a lot of inconvenience when storing and carrying.

Therefore, in recent years, in order to eliminate such inconvenience, various methods have been proposed to draw and wind the wire connected to the earphone from the housing by a predetermined length, but this is a housing for drawing and drawing only the wire connected to the earphone and connecting to various portable electronic products. The plug connected to the wire drawn out to the outside by a certain length from the case is always exposed even when the earphone is not used.Therefore, there is a risk of disconnection or damage, and it is kept unordered. The case of a loss occurs.

In addition, the conventional mobile phone, MP3, CD player, etc. has the disadvantage that the position should always be located in the plug that is always fixed to the outside exposed by a predetermined length from the housing case.

That is, it has been proposed to provide a case having a predetermined shape so that the wire can be stored and used in a more orderly and safe state, but by winding the wire therein so that the wire can be taken out and wound as needed.

Therefore, the present invention is to solve the above problems, the invention is a modified design of the patent application No. 2002-56298 filed by the applicant of the present invention in the form of a reel of the contact around the rotating shaft inside the housing case having a predetermined shape Each wire into the housing case is configured as each bobbin is configured to draw and wind each wire connected to the earphone and the plug from the housing case while maintaining the flow of the signal and maintaining homeostasis according to the contact state of the terminal. It is to provide a wire winding structure that is applied to earphones and plugs that can be handled neatly in order to facilitate user satisfaction with storage and portability.
