Abstract

PROBLEM TO BE SOLVED: To make a cable be wound without use of a reel when not using the cable and maintain an extended state when using the cable.SOLUTION: On a cable body 1, a magnet 5 of which a surface is a positive pole is attached so that a length thereof becomes a half or less of a circumference of the cable body 1, and a magnet 6 of which a surface is a negative pole is attached so that a length thereof becomes a half or less of the circumference of the cable body 1. Then, a magnetic shield part 3 is attached to the cable body 1, which rotates from a position at which the magnetic shield part covers the magnet 5 to a position at which the magnetic shield part covers substantially half of the magnets 5 and 6. When using the cable, the magnetic shield part 3 is rotated to cover the magnet 5 so that magnetism of the magnet 5 is shielded, causing predetermined positions of the cable not to be attracted to each other and a state of the cable to be maintained. On the other hand, when not using the cable, the magnetic shield part 3 is rotated to cover substantially half of the magnets 5 and 6 so that magnetisms of both of the magnets 5 and 6 are not shielded, causing the predetermined positions of the cable to be attracted to each other and the cable to be wound without use of a reel.

Description

  The present invention relates to a cable used for an electronic device or the like, and more particularly to a cable that can be collected when not in use.

  Generally, a cable is used when power is supplied to an electronic device or when an electronic device that performs communication exchanges signals. An electronic device can be used by attaching an electronic device to one end of the cable and attaching an outlet, which is a power supply source, or a partner electronic device that exchanges signals to the other end. By the way, when the distance between the electronic device and the outlet or the distance between the electronic device and the partner electronic device is large, the length of the cable needs to be increased. In consideration of using the electronic device in various places, it is necessary to increase the length of the cable as well.

  However, when the length of the cable is increased, there is a problem that the cable is separated and becomes an obstacle when the electronic device is not used. In order to solve such a problem, a reel for winding a cable is provided between the electronic device and the outlet, the partner electronic device, between the electronic device and the outlet, and between the electronic device and the partner electronic device. A technique is known (for example, Patent Document 1).

  By providing a reel for winding the cable as in the prior art described in Patent Document 1, the cable is wound around the reel when the electronic device is not used, and therefore, the cable is separated and becomes an obstacle. Can be prevented. However, since a reel is required, an electronic device or an outlet is enlarged, or a separate reel is required, which causes a problem that the electronic device or a separately provided reel becomes an obstacle.

  In order to solve such a problem, a technique in which a sheath having magnetized positive and negative electrodes is formed on a part of a cable having a predetermined length, and the cable is wound by bringing the positive electrode of the magnet and the negative electrode of the magnet together. Is known (for example, Patent Document 2).

  However, although the conventional technique described in Patent Document 2 described above eliminates the need for a reel, even when an electronic device is used, the outer shell magnet provided on a part of the cable approaches and the outer shells are attracted to each other. There is a problem that the cables are stuck and cannot be maintained in the extended state.

  The present invention has been made to solve such problems. When the cable is not used, the reel is not required and winding is possible. When the cable is used, the cable is maintained in an extended state. The purpose is to be able to.

  In order to solve the above-described problem, in the present invention, a magnet having a positive surface is attached to a predetermined position of the cable body so that it is at least half of the outer peripheral portion, and at least half of the outer peripheral portion on the opposite side (angle) From a position that covers one of a magnet whose surface is a positive electrode or a magnet whose surface is a negative electrode and a surface whose surface is a negative electrode. It rotates to the position which covers substantially half of the magnet which becomes, and the magnetic shield part which shields the magnetism of a magnet is attached to the outer periphery of a cable main body.

  According to another aspect of the present invention, a magnet is attached to a predetermined position of the cable body so as to be at least half of the outer peripheral portion, and the magnetic body is attached so as to be at least half of the outer peripheral portion on the opposite side. It is attached and rotated from a position covering the magnet to a position covering substantially half of the magnet, and a magnetic shield portion for shielding the magnetism of the magnet is attached to the outer periphery of the cable body.

  According to the present invention configured as described above, the positive electrode and the negative electrode of the magnet are attached to the opposite side so as to be less than or equal to half of the outer periphery of the cable body, and the magnetic shield portion covers approximately half of the outer periphery of the cable body. Since the outer peripheral part of the cable body can be rotated as described above, when using the cable, by rotating the magnetic shield part so as to cover one of the magnet whose surface is a positive electrode or the surface is a negative electrode, The magnetism of the positive electrode or negative electrode of the magnet provided in the cable body is shielded. As a result, the cables are not attracted and can be maintained in an extended state. On the other hand, when the cable is not used, the positive and negative electrodes of the magnet provided on the cable body are shielded by rotating the magnetic shield part so as to cover approximately half of the magnet whose surface is positive and the magnet whose surface is negative. Disappear. As a result, the cables are attracted, and the cable can be wound up without using a reel.

  According to another aspect of the present invention, the magnet and the magnetic body are attached to the opposite side so as to be less than or equal to half of the outer periphery of the cable body, and the magnetic shield part covers substantially half of the outer periphery of the cable body. Since the outer periphery of the cable body can be rotated, when the cable is used, the magnetism of the magnet provided on the cable body is shielded by rotating the magnetic shield portion so as to cover the magnet. As a result, the cables are not attracted and can be maintained in an extended state. On the other hand, when the cable is not used, the magnet provided on the cable body is not shielded by rotating the magnetic shield portion so as to cover approximately half of the magnet. As a result, the cables are attracted, and the cable can be wound up without using a reel.

It is a figure which shows the structural example of the cable by this embodiment. It is a figure which shows the non-use state of the cable by this embodiment. It is a figure which shows the modification of the cable by this embodiment.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a diagram illustrating a configuration example of a cable according to the present embodiment. 1A is a side view showing a configuration example of the cable according to the present embodiment, FIG. 1B is a cross-sectional view taken along the line AA ′ showing a state when the cable according to the present embodiment is not used, and FIG. c) is an AA ′ cross-sectional view showing a state of the cable according to the present embodiment when used. In FIG. 1, 1 is a cable body 1, 2 is a rotating part, 3 is a magnetic shield part, 4 is a linear member such as a power line or a signal line, 5 is a magnet whose surface is a positive (N) pole, and 6 is a surface. Is a negative (S) pole magnet.

  The cable body 1 is linear, and for example, one end thereof is connected to an electronic device. The other end of the cable body 1 is connected to an outlet or a partner electronic device. The cable body 1 has a desired length. Here, the desired length is determined by the distance between the electronic device and the outlet, and the distance between the electronic device and the partner electronic device. In addition, four linear members 4 are embedded in the length direction of the cable main body 1 inside the cable main body 1, and power supply and signal exchange are performed by the linear members 4.

  A magnet 5 whose surface is a positive electrode is attached to a predetermined position of the cable body 1 so as to be at least half the size of the outer peripheral portion of the cable body 1. On the opposite side, a magnet 6 whose surface is a negative electrode is attached so as to be at least half the size of the outer peripheral portion of the cable body 1. Here, the magnets 5 and 6 are attached to a plurality of locations of the cable body 1.

  The rotating part 2 is attached so as to cover the magnets 5 and 6 provided at one place, and is rotatable with respect to the outer peripheral part of the cable body 1. Here, a groove (not shown) is formed in the rotating part 2 over a substantially half circumference, and the convex part provided in the cable body 1 is accommodated. Therefore, a stopper is constituted by the wall portion of the groove of the rotating portion 2 and the convex portion of the cable body 1, and the rotating portion 2 can be rotated over a substantially half circumference. The magnetic shield part 3 is for shielding magnetism, and is provided in a size approximately half of the circumferential direction of the rotating part 2. Here, since the well-known technique is used about the component of the magnetic shield part 3, description is abbreviate | omitted.

  When the rotating unit 2 configured in this manner rotates around the outer periphery of the cable body 1, the rotating unit 2 starts from a position where the magnet 5 whose surface is the positive electrode is covered with the magnetic shield unit 3 (see FIG. 1B). Then, the magnet 5 is rotated to a position (see FIG. 1C) where the magnetic shield part 3 covers substantially half of the magnet 5 whose surface is a positive electrode and the magnet 6 whose surface is a negative electrode. Here, when the rotating part 2 provided in one place is rotated in a certain direction, the rotating part 2 provided in another place also needs to be rotated in the same direction.

  When using the cable comprised in this way, as shown in FIG.1 (b), the magnetic shield part 3 rotates the rotation part 2 to the position which covers the magnet 5 whose surface becomes a positive electrode. Then, the magnetism of the magnet 5 whose surface is a positive electrode is shielded by the magnetic shield part 3. Therefore, the magnetism of the magnet 5 provided at a plurality of locations of the cable body 1 with the surface being the positive electrode becomes invalid and the magnetism of the magnet 6 with the surface being the negative electrode is effective, but the magnetism of the paired magnets 5 exists. The predetermined position of the cable is not attracted.

  On the other hand, when the cable configured as described above is not used, as shown in FIG. 1C, the magnetic shield portion 3 positions the magnet 5 whose surface is a positive electrode (see FIG. 1B). ) To rotate the rotating unit 2 to a position covering substantially half of the magnet 5 whose surface is a positive electrode and the magnet 6 whose surface is a negative electrode. Then, approximately half of the magnet 5 whose surface is a positive electrode is covered with the magnetic shield part 3, and approximately half of the magnet 6 whose surface is a negative electrode is also covered with the magnetic shield part 3. Therefore, the magnetism of the magnet 5 with the surface being the positive electrode and the magnet 6 with the surface being the negative electrode provided at a plurality of locations of the cable body 1 is effective, and the predetermined position of the cable is attracted, as shown in FIG. It can be wound up.

  As described above in detail, according to the present embodiment, the magnet 5 whose surface is a positive electrode is attached to a predetermined position of the cable body 1 so as to be at least half of the outer peripheral portion, and at least the outer peripheral portion on the opposite side is attached. The position where the magnet 6 whose surface is the negative electrode is attached so that the surface is less than half and covers the magnet 5 whose surface is the positive electrode, and the magnet 5 whose surface is the positive electrode and the position where the surface covers approximately half of the magnet 6 which is the negative electrode A magnetic shield portion 3 that rotates in a straight line is attached to the outer periphery of the cable body 1.

  Thereby, the magnet 5 whose surface is a positive electrode and the magnet 6 whose surface is a negative electrode are attached to the opposite side so as to be less than or equal to half of the outer periphery of the cable body 1, and the magnetic shield portion 3 is substantially the outer periphery of the cable body. The rotation part 2 can rotate the outer peripheral part of a cable main body so that half may be covered. Therefore, when the cable is used, the magnetism of the magnet 5 whose surface is positive is shielded by rotating the rotating portion 2 so that the magnetic shield portion 3 covers the magnet 5 whose surface is positive. The cables can no longer be attracted and can be maintained in the extended state. On the other hand, when the cable is not used, the rotating part 2 is rotated so that the magnetic shield part 3 covers approximately half of the magnet 5 whose surface is a positive electrode and the magnet 6 whose surface is a negative electrode, whereby a magnet whose surface is a positive electrode. 5 and the magnet 6 having a negative electrode on the surface are not shielded, so that the cables are attracted to each other, and the cable can be wound up without using a reel.

  In the present embodiment, when the rotating unit 2 rotates the outer periphery of the cable body 1, the rotating unit 2 covers the magnet 5 whose surface is the positive electrode with the shield unit 3 (see FIG. 1B). To a position where substantially half of the magnet 5 whose surface is a positive electrode and the magnet 6 whose surface is a negative electrode is covered by the shield portion 3 (see FIG. 1C), the rotation is not limited to this. . For example, when the rotating unit 2 rotates the outer periphery of the cable body 1, the rotating unit 2 covers the magnet 6 whose surface is a negative electrode with the shield unit 3, and the magnet 5 whose surface is a positive electrode and the surface is a negative electrode. You may make it rotate to the position which covers the substantially half of the magnet 6 which becomes the shield part 3. In this case, it is necessary to adjust the groove of the rotating part 2 and the position of the convex part of the cable body 1.

  Moreover, in this embodiment, although the four linear members 4 are embedded inside the cable main body 1, it is not limited to this. For example, one to three linear members 4 may be embedded in the cable body 1, or five or more linear members 4 may be embedded.

  In the present embodiment, the magnet 5 having a positive surface and the magnet 6 having a negative surface are provided at predetermined positions of the cable body 1 so as to be at least half of the outer peripheral portion. It is not limited to. For example, as shown in FIG. 3, the magnet 10 is attached to a predetermined position of the cable body 1 ′ so as to be at least half of the outer peripheral portion, and the magnetic body 11 is set to be at least half of the outer peripheral portion on the opposite side. May be attached to the outer periphery of the cable body 1 by rotating from a position covering the magnet 10 to a position covering substantially half of the magnet 10 to shield the magnetism of the magnet 10.

  In addition, the said embodiment is only what showed the example in implementation in implementing this invention, and, as a result, the technical scope of this invention should not be interpreted limitedly. In other words, the present invention can be implemented in various forms without departing from the spirit or main features thereof.
