BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire twister device that prevents noise and noise on signal transmission due to an electromagnetic field by twisting a plurality of wires used as a power supply and signal transmission device of an automobile.

Wiring harnesses, which are generally used as power supplies and signal transmission devices for automobiles, have a number of processes including a wire cutting process, a process of crimping a terminal, ie, a terminal and a wire, and a process of connecting a multicap. Produced. As such, wires in which terminals are crimped, which is one of the main components of the wire harness manufacturing process, are arranged in close proximity to each other in the device. Thus, when the wires are closely connected to each other, electromagnetic fields generated from each other are generated. ), They interfere with each other, causing noise.

Therefore, in order to remove the cause of the noise caused by the electromagnetic field between the adjacent wires, the adjacent wires have been twisted with each other to cancel the noise caused by the mutual electromagnetic fields.

 1 is a diagram showing a conventional wire twister device used to twist between wires. In the conventional wire twister device, as shown in FIG. 1, one end of the wires 131 and 132 is fixed to the fixing body 120 and the wires are rotated by the rotation of the rotating body 110 according to the rotational force of the twisted motor 100. I had a twisted structure. As a result of twisting the wire using the conventional wire twister device, a twist wire as shown in FIG. 2 is formed. As a result, a wire loosening phenomenon occurs due to elastic force as time passes. When the wire unwinding phenomenon occurs as described above, there was a problem that the electric field noise is generated due to the unsatisfactory condition of the pitch indicating the twist cycle interval. In order to solve the problem as described above, the wire unwinding prevention measures to prevent wire unwinding over time by taping at a predetermined distance (interval) as shown in FIG. 3. However, after twisting the wires as described above, taping 301 at regular intervals as shown in FIG. 3 results in inefficiency of the work and consequently cannot be a fundamental measure against wire loosening.

The present invention has been made to solve the above problems, and an object of the present invention is to propose a wire twister device and an operation process for preventing the twisting of the wires used in the wiring of the harness of the vehicle.

In order to achieve the above object, the present invention, after connecting the front end of the first wire used in the vehicle harness wiring to the first rotating body and fixing the front end of the other second wire to the main body, and then rotating the first rotating body A first twist motor which twists only the first wire by itself, and a rear end of the first wire and a rear end of the second wire to a single second rotating body, and then rotates the second rotating body to Receives and displays a second twist motor for twisting each other between the first twisted wire and the second twisted wire that are not twisted with each other, and the number of turns N to be twisted, and displays the twist of the first wire. After the completion of the casting, the first twisted motor and the second twist so that the first twisted wires and the second twisted wires which are not twisted with each other are twisted with each other. Includes the emitter the twist motor control unit for supplying a rotational drive force in accordance with the sense of Soo received input individually.

In addition, the present invention is a step of receiving the number of turns (N) to be twisted to display the same, and according to the twisting operation request by rotating the first rotating body connected to the front end of the first wire itself to the first wire Twisting, and the rear end of the first wire and the rear end of the second wire rotate the second rotating body connected to the single second rotating body so as not to twist the first and self twisting wires. Twisting the second wires together.

Hereinafter, the detailed description of the preferred embodiments of the present invention will be described with reference to the accompanying drawings. In the following description of the reference numerals to the components of the drawings it should be noted that the same reference numerals as possible even if displayed on different drawings.

4 is a diagram illustrating a wire twister according to an embodiment of the present invention.

The present invention has a structure in which only one wire twists itself, and then twists it again between the wires. That is, the first twisted motor 410 twists only the first wire 431 itself, and the second twisted motor 420 twists the first wire 431 and the second wire 432 with each other to finally twist the first wire 431 itself. To complete the twisted wire. Conventional wire twister device has a structure of twisting the wires with each other without twisting the wire itself, the present invention has a structure of twisting the wire itself first and then twisting the wires with each other. Twisting the wire itself as described above is the same as the principle of the spring handset of the telephone. That is, in the case of the spring handset of the telephone, the telephone line is folded in half when twisted down when the receiver is turned in the turned state, but the self-twisting state is maintained unless the handset is lifted and rotated again in the opposite direction. In the present invention, this self-twisting principle is used.

Referring to FIG. 4, a first wire 431 and a second wire 432 are connected to the first twist motor 410, and the front end of the second wire 432 is the first wire. The twisted motor 410 is fixedly connected to the main body, and the front end of the first wire 431 is connected to the first rotating body 411. In addition, the rear ends of the first wire 431 and the second wire 432 are fixedly connected to a single second rotating body 421 connected to the second twist motor 420. Accordingly, when the first rotating body 411 is rotated according to the rotational force of the first twisted motor 410 after the second rotating body 421 is fixed, the first wire is rotated by the first rotating body 411. Only 431 has a structure that is twisted a predetermined number of times.

After the first wire 431 is self-twisted by the first rotating body 411 as described above, the second rotating body 421 is rotated by the rotational force of the second twisting motor 420, The first wire 431 and the second wire 432 connected to the second rotating body 421 are twisted with each other to finally form a twisted wire.

The twist motor control unit 500 is a unit for supplying the rotational force of the first twist motor 410 and the second twist motor 420, as shown in Figure 5, the control unit 506, display unit 501, sense A number input button 502, a start button 503, a first twist motor driver 504, and a second twist motor driver 505 are provided.

When the number of turns for twisting the wire is received from the user through the number of turns input button 502, the number of turns received is displayed on the display unit 501. When the start button 503 is pressed by the user after the winding number input is completed, the first twist motor driver 504 supplies a rotational driving force to the first twist motor 410 according to the winding number, and similarly, According to the number of turns, the second twist motor driver 505 supplies a rotational driving force to the second twist motor 420. Each of the above processes is performed according to a control algorithm of the controller 506. The operation algorithm is illustrated in FIG.

FIG. 6 is a flowchart showing the operation steps of the twisted motor control unit, and FIG. 7 is a diagram showing the timing pulses in each operation step.

Referring to FIGS. 6 and 7, first, when the N-number push push input S602 is received through the number-of-number input button, the number of times of the number-of-number input button is pressed is displayed on the display unit. Is displayed (S604). When the start button is input from the user after the winding number input is completed (S606), the first twisted motor driver 504 supplies a rotational driving force to rotate the clockwise N times to the first twisted motor 410 to transmit the first wire. Twist itself N times clockwise (S608). After the N twisting with respect to the first wire 431 is completed, the second twist motor driver 505 supplies a rotation driving force for rotating N times in a counterclockwise direction to the second twist motor 420 to supply the first twisted wire. The wire 431 and the second wire 432 are twisted N times in the counterclockwise direction (S610).

In the above, the first twist motor twisting only the first wire 431 is rotated in a clockwise direction, and the second twist motor twisting each other between the first wire 431 and the second wire 432 is counterclockwise. It is only one embodiment of the invention. As another embodiment of the present invention, the first twist motor may be rotated counterclockwise, and the second twist motor may be rotated clockwise.

After twisting only the first wire through the above steps and then twisting the first and second wires together, the loosening does not occur when the connector is assembled at both ends of the wire in this state. After mounting, wire loosening does not occur on the same principle.

Meanwhile, when the two wires 431 and 432 are twisted with each other by using the wire twister of FIG. 4, since the lengths of the two wires are different, the degree of deformation during rotation is different. In addition, since the first wire 431 has its own small additional deformation once than the second wire 432, there is a concern about a change in wire characteristics and a difference in characteristics between the two wires. Therefore, there is a disadvantage that the noise can be introduced into the wire due to the above characteristics difference. In another embodiment of the present invention to overcome the above disadvantages, a wire twister device as shown in FIG. 8 is proposed.

8 is a diagram illustrating a wire twister device according to another embodiment of the present invention.

Unlike the wire twister of FIG. 4, the wire twister of FIG. 8, which is another embodiment of the present invention, twists the first wire 431 and the second wire 432 individually through the first twist motor 410. The second twisted motor 420 then twists the two wires 431 and 432 with each other. To this end, unlike the wire twister of FIG. 4, the wire twister of FIG. 8 has a feature in which the first twist motor 410 includes the first-first rotor 811 and the first-second rotor 812. . The front end of the first wire 431 is connected to the first-first rotating body 811 and the front end of the second wire 432 is connected to the first-second rotating body 812 so that the wires are individually Twisting is done. FIG. 9 is a perspective view illustrating an internal configuration of the first twister motor 410, and includes a first-first gear 911 and a first-second rotor 812 for rotating the first-first rotor 811. The first and second gears 912 for rotating the gears are interlocked with the motor gears 910. When the motor gears 910 rotate in the counterclockwise direction, the first to first gears 911 and the first to second gears 911 are rotated. 912 can be rotated individually clockwise.

Referring to the operation process of the wire twister of FIG. 8 briefly, when the number of times of the number of push input button is received through the number of turns input button, the number of turns N is pressed on the display unit as many times as the number of turns of the input button is pressed. Is displayed. When the start button is input by the user after the winding number input is completed, the first twist motor driver 504 supplies a rotation driving force to rotate the N times in the counterclockwise direction to the first twist motor 410 for the first time. The first wire 431 and the second wire 432 are individually twisted N times in the clockwise direction by rotating the whole 811 and the first-second rotating body 812, respectively. FIG. 10 shows the self-twisting of N times for the first wire 431 and the second wire 432.

 After the self-twisting of the respective wires is completed as described above, after the rotation of the first twister motor 410 is stopped and fixed, the second twist motor driver 505 rotates N times in a counterclockwise direction. It is supplied to the second twist motor 420 to rotate a single second rotating body 421 to twist the first wire 431 and the second wire 432 N times in the counterclockwise direction. Complete together.

As described above, by rotating the second twist motor 420 in the fixed state of the first twist motor 410, the two wires 431 and 432 are twisted with each other by the elasticity to return to the circular state. Thus, although a small deformation occurs, each strand of the twisted wire that has completed all the above steps is restored to a circular state so that no further deformation occurs.

In the foregoing description of the present invention, specific embodiments have been described, but various modifications may be made without departing from the scope of the present invention. Therefore, the scope of the present invention is not to be determined by the embodiments described above, but will be apparent in the claims as well as equivalent scope.

As described above, the present invention is applied to the twisting of the wires used in the harness wiring of the vehicle by applying the elasticity and the mating of the object, thereby preventing the loosening of the twisted wire. Therefore, by preventing the loosening of the twisted wire has the effect of preventing the induction of electric field noise to improve product quality and performance.
