Abstract

The present invention relates to a handsfree or earphone for a mobile phone and a jack used for various audio devices.

According to the present invention, the detachable method of the jack of a car handsfree device or a mobile phone and earphones of various electronic devices can be easily and easily detached using a magnetic force of a magnet in a conventional insertion type. ② It is composed of magnetic joints.

Description

Magnetic Jack {MAGNETIC JACK}

The present invention relates to a jack of various earphones or hands free to facilitate the detachment of the jack using magnetic force.

In general, the detachment of earphones or hands-free, such as a mobile phone is a method of inserting the jack after removing the rubber cap ① for protecting the device of the mobile phone as shown in FIG.

In this case, the rubber cap is designed so small and difficult to peel off, which makes the jack detachable and cumbersome, and it is inconvenient to refit the rubber cap after use in order to prevent dust or foreign substances from entering the device at all times.

The purpose of the present invention is to improve the convenience of use by changing the detachable method of the jack from the insertion type to the magnetic contact type, and to help the vehicle safety operation by increasing the amount of use by the ease of use when using the hands free.

4 is an exemplary view showing a mounting method according to an embodiment of the present invention

According to the present invention, a jack-carrying part permanently mounted on the receptacle of various electronic devices for a mobile phone is shown in Fig. 3 ①, and a connecting portion incorporating a magnet in contact with this is shown in Fig. 3-2.

When described with reference to the accompanying drawings a preferred embodiment of the present invention as follows.

Figure 2 shows a mobile phone connected to the magnetic contact jack according to the present invention is composed of a jack connection portion ① that is permanently mounted by connecting to a receptacle such as a mobile phone and the connection portion ② of the magnetic built-in connected by this jack connection portion and magnetic force. .

Jack Connection Figure 3-① can be attached and detached by a gap and a receptacle for fixing a rubber stopper of a receptacle part such as a mobile phone, and is designed to be small in size. Afterwards, it was designed to be permanently installed in appearance and use.

Also, in order to increase the contact force and electrical conductivity based on the magnetic force generated in the magnet part of Fig. 3-④, the contact parts Fig. 3-③ and Fig. 3-⑤ are made of strong magnetic material, and the surface can be improved through plating of conductive material. Designed to be. And other parts except this contact part were designed to be nonmagnetic considering the influence of the device by magnetic force.

And when contact is connected, the projection part of Figure 3-⑤ is inserted into the groove of Figure 3-③ and is mounted in contact with the magnet part of Figure 3-④. .

Referring to Figure 4, which is a detailed view ...

Figure 4-1 of the anode portion and the microphone and earphone of Figures 3-2, 3 It consists of the cathode part and the insulators of FIGS. 3-4 and 5

Magnet built-in connection part Figure 3② is composed of magnet part ⓑ and anode ⓐ, cathode ⓒ, ⓓ insulation part ⓔ, ⓕ in Fig. 4, which is a detailed drawing. It is effective to increase the contact area by magnetically connected with the parts of Figure 4-2 by reducing the influence of the magnetic force of the ⓒ part in contact with the outside when it is not used by the gap to block the It is designed to enhance the size of the contact force.

In the case of the jack contact part (Fig. 3-②), the area of Fig. 3-⑤ part and Fig.3-③ part is designed to increase the contact force when the receptacle connection part is in contact with Fig. 3-①. It was designed to be. And in the case of Figure 4-ⓐ part and Figure 4-1 can be secured to increase the efficiency of the electrical contact through the spring device.

In the case of Fig. 4-1, it is designed to be recessed from the surface to prevent an error caused by the electrical contact between Figs. 4-2 and 3 and the human body or various conductors.

As described above, according to the present invention, the jacks of the earphones of various acoustic devices such as hands-free devices for mobile phones, earphones for mobile phones, or wireless communication devices are improved for the convenience of use and for the safe operation by encouraging the use of hands-free while driving the vehicle. I expect this to be.
