Description

Earphone wire twist prevention device {Earphone wire twist prevention device}

The present invention relates to an earphone wire twist prevention device, and more particularly, the connection portion of the first wire and the second wire, each of which connects the earphone speaker and the jack, to be energized, is coupled to allow slippage and twisting of the wire. The present invention relates to a device for preventing twisting of earphone wires.

In general, electric wires for supplying power are used in various electronic products such as lighting devices, telephones, and earphones.

However, since the ends of the wires used to supply power in various products are fixed, the handset that rotates the lighting fixture or configures the telephone repeatedly to control the direction of light irradiation is repeatedly used. In the case of being twisted as well as the appearance is bad, there is a problem that is very uncomfortable in use.

In addition, there is a serious problem that the power supply is cut off the wire strands if the twisting of the wire continues repeatedly.

In particular, since the earphone wire is thinner than other wires, the two wires are easily twisted, and there is a difficulty in releasing the twisted earphones even when the earphone is taken out and used.

Untie the earphones that were stored and connect them to the mobile phone. If you put two amplifiers in your ear, the string twists itself in the middle, causing inconvenience.

Also, while walking or playing with earphones, the strings are entangled by themselves. To solve this problem, you have to unplug the two amplifiers that are already plugged in and unplug them, or separate the phone and earphones and unplug them again. The downside is that you have to do something cumbersome every time the music breaks up and the strings get tangled. What's more, if your phone is in your pocket or bag, it's harder to unwrap it in the same way.

Accordingly, recently, Korean Utility Model Registration No. 20-0220516 (name: wire twist prevention device) has been proposed as a technology for preventing the twisting of the wire as described above.

The prior art of the Republic of Korea Utility Model Registration No. 20-0220516 is a bar body formed in step 2 is formed integrally at the bottom, the wire is embedded, but is connected to the electrode portion is formed interpolated at the bottom of the rod concrete; A connection body formed with a hole into which a rod is inserted, a connection rod inserting hole into which a connecting rod is inserted, and integrally connected to an electrode part and an electric wire formed at a position corresponding to the electrode part of the rod; The rod is inserted into the coupling body is formed with a flow hole to be grounded while the assembly and the connector is free to rotate, the connecting rod is formed with a fixed pin insertion hole is inserted into the fixing pin; And it is configured as a 'pin, by allowing the assembly and the connection to be rotated freely to prevent the twisting of the wire and at the same time it is to be easily released by simply rotating one side even if the wire is twisted.

However, in the above prior art, there is a problem in that the structure is very complicated as a separate electrode portion is to be formed inside the rod and the connecting body.

Accurate or absolute figures are used to assist in the prevention of unfair use by unscrupulous infringers.

1 is a perspective view showing an earphone to which the earphone wire twist preventing device of the present invention is applied, and FIG. 2 is a sectional view showing the earphone wire twist preventing device of the present invention.

First, as shown in Figures 1 and 2, the earphone wire twist prevention device of the present invention is the first wire 110, the first holder 130, the second holder 140, the second wire 120, the first terminal 150 and the second terminal. It consists of 160.

The first wire 110 and the second wire 120 is a general audio wire is applied.

Then, the speaker 11 and the jack 12 for earphones are installed at one end of the first wire 110 and the second wire 120, respectively.

The first wire 110 is connected to the first holder 130 and the second wire 120 is connected to the second holder 140.

Here, the first wire 110 and the second wire 120 are electrically connected to the first holder 130 and the second holder 140.

In addition, the first holder 130 and the second holder 140 are rotatably coupled to each other.

In addition, a first terminal 150 is installed on the inner circumference of the first holder 130 and is energized with the first wire 110, and a second terminal 160 contacting and slipping with the first terminal 150 is connected to the second wire 120. The first wire 110 and the second wire 120 maintain the contact state between the first terminal 150 and the second terminal 160 while idling the first holder 130 and the second holder 140.

Here, the first terminal 150 is provided with a plurality of brush terminals 151 at equal intervals to connect the internal wires 115 of the first wire 110 to each brush terminal 151, the second terminal 160 is a plurality of slip terminals 161, etc. The inner wires 115 of the second wire 120 are connected to each slip terminal 161 by being spaced apart from each other, and the brush terminal 151 and the slip terminal 161 may be in contact with each other and slip.

The second terminal 160, which is in contact with the first terminal 150 and slips, is connected to the second wire 120 so that the first wire 110 and the second wire 120 are idling with each other between the first holder 130 and the second holder 140. The contact state of the second terminal 160 is maintained.

In other words, the first wire 110 and the second wire 120 each consist of four internal wires 115.

Internal wire 115 is composed of power, positive power, negative power and sound wire.

The inner wires 115 of the first wire 110 and the second wire 120 should be connected to wires having the same purpose.

To this end, the first terminal 150 is installed in the inner space 132 of the first holder 130, the second terminal 160 is installed on the outer periphery of the second holder 140.

The first wire 110 is connected to the first terminal 150 and the second wire 120 is connected to the second terminal 160.

In this case, the first terminal 150 is provided with a plurality of brush terminals 151 at equal intervals to connect the internal wires 115 of the first wire 110 to each brush, the second terminal 160 is a plurality of slip terminals 161 at equal intervals. The inner wires 115 of the second wire 120 are connected to the slip terminals 161.

Here, the brush terminal 151 and the slip terminal 161 to be in contact with each other and slip.

In particular, the brush terminal 151 is made of a metal material and provided with a plurality of thin metal yarns are bundled in a bundle.

This enables the brush terminal 151 to be energized while having its own flexibility, thereby allowing the brush terminal 151 to maintain the energized state while maintaining elasticity in contact with the slip terminal 161.

In addition, an inlet 131 is formed in the inner space 132 of the first holder 130 to facilitate rotation of the first holder 130 and the second holder 140, and the inlet 131 and the bottom of the inner space 132 contacting the second holder 140. Install a bearing 170 in between.

As described above, the earphone wire twist prevention device 100 of the present invention is coupled to allow the slippage of the wires connected to the first wire 110 and the second wire 120 connecting the earphone speaker 11 and the jack 12 so as to enable electricity to twist the wires. It is effective to prevent this.

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications, and changes are possible within the scope without departing from the technical spirit of the present invention. It will be evident to those who have knowledge of.
