The present invention relates to earphone wire automatic winding, and more particularly, to a rotating part, a connector, a rotating center part, a driving part.

In addition, the earphone wire is made to be miniaturized and lightweight at the time of the wire rewinding by minimizing the volume by using an ultra-fine cable, it can be embedded in devices such as portable audio equipment, mobile phones, laptops.

In the conventional portable telephone or audio equipment, it was mainly used as a voice transmission function for a call, such as a general universal earphone or an earphone equipped with a remote control, or a earphone for hanging around the neck. In addition, there is no commercially available portable phone or audio device that can listen to high quality and high volume with earphones and has a function of automatically winding or unwinding microphone and earphone wires.

Existing products were not easy to carry and use because they were not organized, and they were also lost. The frequency of breakage due to entanglement and twisting of microphone and earphone wires was high, and the sound quality and volume were low. There was a lot of inconvenience.

Especially when carrying or talking on the phone while carrying earphones or hands-free, if the surrounding noise and noise are too low or the sound is too small, most of the time, you can take out the earphone and pick up the phone directly, or immerse yourself in the conversation. This phenomenon has led to a decrease in concentration, leading to an increase in safety accidents.

However, while recognizing the need, there was a tendency to avoid the use due to inconvenience and troublesome. In addition, technically, wire winding was not simplified and reliability was guaranteed. Existing materials were limited to thinning the microphone and earphone wires to reduce the volume, and to improve the performance of earphones with high quality sound and volume. As a result, it was not technically difficult to realize miniaturization, light weight, high performance, low cost production, and the like.

If the development of wire auto-reel applying the commercially available microphone and earphone wires as it is becoming increasingly smaller and lighter, it is hard to carry portable devices due to the increase in the size and weight of the wire auto-reel due to the thickness of the microphone and earphone wires. There is a problem that is difficult to embed in.

Therefore, the present invention is to solve all the disadvantages and problems of the prior art as described above, the earphone wire automatic reel is briefly as a rotating part, a connector, a rotating center part and a driving part through an optimized design for realizing miniaturization and reliability Configured. In addition, by applying a DC motor, a spiral steel spring or a manual gear, the drive unit can be wound or unwound the wire automatically or manually, as well as the length can be adjusted, thereby causing damage due to tangling and twisting of the wire Lowered the frequency.

In addition, the earphone wire is an object of the present invention to provide an automatic wire winding of the earphone wire which can be manufactured or built into a portable device by improving the miniaturization, light weight and reliability of the wire reel by using a thin, flexible and excellent ultra-fine cable. .

The object of the present invention is a rotating unit 110, the earphone wire is wound; A rotation center 130 which is fixed to the PCB while being the axis of rotation so that the rotation unit can rotate; A connector 120 which is in electrical connection with the rotation center part in a state of being connected to the earphone wire and has a simple coupling with the rotation part; And by the automatic winding of the earphone wire consisting of a drive unit 140 for rotating the rotating unit.

The PCB may be a PCB of an audio device to which earphone wires such as a mobile phone, an MP3, a portable CD player, and the like are applicable.

The rotating part is a gear wheel 112, a manual gear wheel (143-1) or a spring wheel (according to the method of the drive unit 140 is selected to wind or unwind the rotating part as a basic component of the wheel 111, the earphone wire winding) 145) to select and attach.

The driving unit is divided into a DC motor 141, a spiral steel spring 144, and a manual gear 143-1, respectively, by directly engaging the gear wheel, the spring wheel and the manual gear wheel or connecting a belt to the power to the wheel. Will be delivered.

The solder lead terminal 132 and the contact terminal 133 of the rotation center are electrically connected inside the rotation center, and the number is the same as the number of channels of sound.

The contact lead terminal 122 and the micro terminal 123 of the connector are electrically connected inside the connector, the number of which is equal to the number of channels of sound.

Details of the above object and technical configuration of the present invention and the effects thereof according to the present invention will be more clearly understood by the following detailed description with reference to the drawings showing preferred embodiments of the present invention.

1 is an exploded perspective view of a built-in earphone wire automatic reel using a DC motor.

First, the center of rotation 130 is fixed to the PCB, the soldering lead terminal 132 for the PCB connection for electrical connection to the PCB, and fixed to the PCB by the PCB fixing support 131. When the rotation center part is fixed to the PCB, the wheel 111 of the rotation part 110 in which the wire is wound is coupled to the rotation center part, and the gear wheel 112 is attached and fixed to the top of the wheel 111. After assembly, the DC motor is fixed to the PCB so that the motor gear 141-2 of the DC motor and the gear wheel 112 of the rotating unit engage with the DC motor 141-1, which is the driving unit 140, to engage the motor. The rotating unit is rotated by driving. If the motor gear 141-2 and the gear wheel 112 cannot be assembled to engage, the power of the motor gear can be transmitted to the gear wheel by using a separate belt.

Combination of the wheel 111 and the rotation center 130 of the rotating unit is made through the fixing unit 116 for the rotation center portion of the wheel, and after the rotation center and the wheel is coupled, to the connector coupling fixture 114 of the wheel Insert the connector 120 is coupled to the fixed lock (121). However, before the connector is coupled to the wheel, the earphone wire 200 is previously connected to the micro terminal 123 of the connector by soldering.

The earphone wire 200 is a wire end display (200-1), according to the purpose can be added to the configuration having other functions, such as the microphone 300 and the remote control.

The connector 120 is composed of a fixed lock 121 and a contact lead terminal 122 for electrical connection with the contact terminal 133 of the rotation center portion for coupling with the wheel. When the connector including the contact lead terminal 122 made of high-elastic copper alloy is inserted toward the contact terminal of the center of rotation shown through the connector coupling fixture 114 of the wheel, the contact lead terminal of the connector and the center of rotation of the connector The contact terminals are coupled so that they are electrically connected. The contact lead terminal was processed into a high-elastic copper alloy in the form of an open end, and then plated with gold, silver or platinum having excellent conductivity, so that the signal could be transmitted without noise.

In addition, the micro terminal 123 of the connector is equal to the number of contact terminals of the rotation center and the contact lead terminal 122 of the connector, and if the earphone wires are connected in accordance with the number of the micro terminal, the sound of the multi-channel You can hear it.

The contact terminals 133 of the rotation center are arranged in a concave-convex shape at regular intervals in the form of a circular ring in a small cylindrical shape at the top of the rotation center for electrical contact with the connector. The contact terminal may be made of a metal having excellent conductivity such as gold, silver, or platinum, or may be plated to transmit an electrical signal without noise. Since the contact terminals have a concave-convex shape, after the contact lead terminals of the connector are coupled, the contact lead terminals of the connector are in a continuous electrical connection state without detachment from the contact terminal of the rotation center despite the rotation of the rotating unit. . In addition, the contact terminal of the rotation center portion and the contact lead terminal of the connector is manufactured by engineering plastic molding precisely by using each mold to move smoothly without rotation during rotation.

The number of solder lead terminals and contact terminals for the PCB connection part and the contact lead terminals and micro terminals of the connector corresponds to the number of channels of sound. That is, the number of terminals is increased or decreased according to the number of channels.

Finally, in order to be able to adjust the winding and unwinding the earphone wire, the lock gear wheel 113 is fixed to the top of the gear wheel 112 of the rotating part coupled to the rotation center portion and then fixed to the top of the lock gear wheel After the stopper 150 is coupled to the center of rotation, the fixing screw 135 is screwed into the screw hole 134 of the center of rotation. The stopper is composed of a stop ring 151, a spring for stopping action 152 and the wire winding button 153. When the stop device is coupled as described above, the stop ring 151 by the stop action spring 152 is always caught only in the rotational direction in which the earphone wire is wound around the lock gear wheel 113, so that the wire is wound. Only when the button 153 is pressed, the earphone wire is wound to adjust the rotation of the rotating unit by using the wire winding button 153.

Of course, when the earphone wire is released, the stop ring is locked only in the rotational direction in which the earphone wire is wound, so the rotating part rotates without pressing the wire winding button so that the earphone wire is released.

Connect one end of the spiral steel spring 144 to the spring fixing wheel 146, and then tighten the spiral steel spring as much as possible to wind the spiral around the spring fixing wheel, and then roll the steel plate spring with the clip so that the wound steel spring is not released. Tie it up. After attaching and fixing the spring fixing wheel in which the steel spring is spirally wound to the center of rotation, it is combined with the spring fixing wheel in which the steel spring is wound, and then one end of the steel spring wound around the spring fixing wheel is connected to the spring wheel. . Next, after attaching and fixing the wheel 111 to the top of the spring wheel, the lock gear wheel 113 is fixed to the top of the wheel.

The spring wheel 145 and the spring fixing wheel 146 to be fixed to a high elastic spiral steel plate spring 144, between the spring wheel and the spring fixing wheel is a high elastic steel spring is wound in a spiral state. When the wheel 111 is rotated and the earphone wire is wound, the spiral steel spring is released. On the contrary, when the earphone wire is released, the spiral steel spring is wound. The length of the steel sheet spring is the length that the winding of the steel sheet spring is not finished until the earphone wire is completely wound.

The coupling process to the stop device 150 is the same as the built-in automatic wire reel using the DC motor.

When the coupling is finished until the stopper is released, the steel wire spring is released and the earphone wire is wound as the steel plate spring is released. Built-in automatic wire reel using a spring, when unwinding the earphone wire by pulling by hand, when winding the wire winding button (153) by pressing.
