Description

[Detailed Description of the Invention] The present invention relates to an earphone plug with a winding function, which has a function of winding an earphone cord around the plug.

The purpose of the present invention is to connect a cord pulled out from a point near the plug of an elongated insulating plug sheath through which the cord of the plug is passed, in an earphone device in which a plug is connected to one end of the cord and an earphone is connected to the other end. To provide an earphone plug which can be rolled up and stored between two annular flanges provided at a distance in the center of a sheath.

A handset is used to listen to audio from a radio or television receiver without outputting it through the speakers.

As shown in the example of FIG. 1, conventional telephone receivers generally have a lead wire 2 consisting of a pair of coated wires connected to an earphone 1, and the two ends of the lead wire 2 are connected to the tips 4 and 4 of a plug 3, respectively. It is connected to an insulated sleeve 5, and the lead wire 2 side of the plug 3 is covered with a cylindrical plug 6 for insulation and handling purposes.

Since this type of telephone receiver has a long code 2, processing the code 2 can be troublesome when not in use.

It is usually rolled up and tied, or folded and tied with a band.

When it is used again, the cord 2 is often tangled, which is inconvenient in use.

Also, if the cord is repeatedly folded and tied, the conductor of the cord may break, requiring careful handling, and may result in a lack of reliability.

In order to eliminate the drawbacks of the conventional technology, the present invention provides a winding frame with two annular flanges spaced apart from each other on the plug sheath.
This invention relates to an earphone plug in which an earphone cord is wound between two annular collars.

As shown in FIG. 2, an embodiment of the present invention, the plug 3 includes:
Chip 4 connecting one of the l pairs of conductors of code 2
, a sleeve 5 to which another conductor is connected and which becomes the ground side, and a plug terminal 7 for connecting to this sleeve 5 and mechanically fixing and holding the cord 2.

Therefore, in this embodiment, a recess 8 that prevents mutual rotation even when the plug terminal I is inserted into one end of the sheath, a pull-out hole 9 for letting the cord 2 out from inside the sheath, and two annular flanges are provided. 10.
A winding sheath 12 of insulating material is connected to the plug 3, provided with a winding frame 11 fixed at intervals of 10'.

The cord 2 connected to the plug 3 is taken out of the winding sheath 12 through the pull-out hole 9.

Furthermore, the plug sheath 6 is fitted into the winding sheath 12.

A ring-shaped convex portion 13 is provided on the inner surface of the other end of the other winding sheath 12.

Further, in the middle of the cord 2, there is a bundle rod 15 having a hole 14 through which the cord 2 passes, and a rotating tool 18 in which the bundle rod 15 is fixed around the periphery and several springs 17 having protrusions 16 at the tips are integrally fixed. Pass it through the cord 2, attach the earphone 1 to the end of the cord 2, and connect.

Furthermore, slits 19 are provided in the annular flanges 10, 10' on both sides of the winding frame 11 from the periphery toward the center as shown in FIG.

In this way, when the earphone of the present invention is not in use, the cord 2 is inserted into the slit 19 of the collar 10 using the rotating tool 18.
When the spring 17 is inserted into the end of the winding sheath 12, the spring 1
The protrusion 16 of 7 is housed in the convex portion 13 of the winding sheath 12.

When the bundle rod 15 is rotated, the cord 2 passing through the hole 14 at the tip of the bundle rod 15 is wound around the winding frame 11 in several layers.

Therefore, the cord 2 is not only organized in the end case, but also when the cord 2 is long, the length of the cord to be used can be freely adjusted by stopping the winding midway.

When using again, the cord 2 wound around the reel 11
All you have to do is turn the rotary tool 17 in the opposite direction to untie it.

In FIG. 2, the plug 3 and the winding sheath 12 are connected by the plug terminal 7 and the four parts 8, and are fixed by the plug sheath 6, but as another embodiment, as shown in FIG. ,
When the plug and the plug sheath are connected by a male thread 20 and a female thread 21, the female thread 21 may be provided so that the tip of the winding sheath 12 is fitted with the plug.

As described above, according to the present invention, there is no need for troublesome cord disposal when not in use, unlike in the past, and there is no need for cords to get tangled when used on the surface, and the cords can be wound up in an organized manner on the winding frame. Therefore, it is easy to handle, and in the case of a long cord, the length can be adjusted freely by winding it halfway, and it also prevents the cord from breaking due to handling, which increases reliability. There is.
