The clip body 10 has a flat portion 12a of the pair of clip pieces 12 and 12 in contact with each other at the center, and slope portions 12b and 12b are opposed to each other in a V shape at both ends.

  2A and 2B are explanatory views showing the appearance of the clip piece 12 to which various members are attached. FIG. 2A is a plan view and FIG. 2B is a side view. 3 is a cross-sectional view of FIG. 2A, FIG. 3A is a cross-sectional view taken along line AA, and FIG. 3B is a cross-sectional view taken along line BB. For convenience of the following description, the surface of the clip piece 12 shown in FIG. In the clip piece 12 shown in FIG. 2A, a direction perpendicular to the longitudinal direction (X direction in FIG. 2A) is referred to as a width direction (Y direction in FIG. 2A). In the clip piece 12 shown in FIG. 2B, a direction perpendicular to the longitudinal direction (X direction in FIG. 2A) is referred to as a contact / separation direction (Z direction in FIG. 2B). The longitudinal direction, the width direction, and the contact / separation direction are perpendicular to each other.

  As shown in FIG. 2A, a recess 12c is formed at the boundary between the flat surface portion 12a and the slope portion 12b on the surface of the clip piece 12. Two recesses 12 c are formed on the surface of the clip piece 12. Moreover, the surface of the boundary part between the plane part 12a and the slope part 12b is formed in the circular arc surface.

  Further, a rectangular parallelepiped recess 12d extending in the longitudinal direction is formed in a region between the two recesses 12c on the surface of the flat portion 12a. This recess 12d corresponds to a first recess. A plurality of plate-like partition portions 12e are provided inside the recess portion 12d, and the recess portion 12d is partitioned into a plurality of partition recess portions 12f by the plurality of partition portions 12e. The plurality of partition recesses 12f are aligned at equal intervals along the longitudinal direction. In the present embodiment, five partition recesses 12f are formed. The number of the partition recesses 12f may be more or less than that, but is preferably at least three.

  Moreover, as shown to Fig.3 (a), the recessed part 12c is set to the magnitude | size in which the magnet 14 can be inserted. Further, the partition recess 12f is capable of accommodating the roller 16 and is formed deeper than the diameter of the roller 16. Further, two coil springs 18 are accommodated in the partition recess 12f.

  Moreover, as shown in FIG.3 (b), the long hole 12g is formed in the both sides | surfaces which oppose the width direction of the clip piece 12 in the internal side surface of the division recessed part 12f. The elongated hole 12g extends in the contact / separation direction.

  A magnet 14, a roller 16, a coil spring 18, a cap 20, and a rubber member 22 are attached to the clip piece 12 thus configured.

  The magnet 14 is a permanent magnet that is inserted into the recess 12 c of the clip piece 12. As the magnet 14, for example, a magnet having a high attractive force such as a neodymium magnet can be used. The shape of the magnet 14 is set so that the surface of the magnet 14 is flush with the surfaces of the inclined surface portion 12b and the flat surface portion 12a when the magnet 14 is fitted into the recess 12c. Further, the magnetic poles on the surface of the magnet 14 are made different from each other in the pair of clip pieces 12 and 12. Specifically, the magnetic poles on the surfaces of the magnets 14 and 14 of one clip piece 12 in the pair of clip pieces 12 and 12 are N poles, and the magnetic poles on the surfaces of the magnets 14 and 14 of the other clip piece 12 are S poles. Is set to be Thereby, a pair of clip pieces 12 and 12 are integrated as shown in FIG.

  FIG. 4 is a perspective view showing a structure for attaching the roller 16 and the coil spring 18 to the clip piece 12. The roller 16 includes a roller body 16a in which a cylindrical through hole is formed along the central axis, and a rotating shaft 16b that is inserted into the through hole of the roller body 16a and rotatably supports the roller body 16a. ing. On the roller surface of the roller body 16a, grooves extending in the central axis direction are formed side by side in the circumferential direction. A rotation shaft 16b extends from the center of both sides of the circular shape of the roller body 16a. Both ends of the rotating shaft 16b are loosely fitted into the long holes 12g shown in FIG. As a result, the roller 16 is rotatable inside the partition recess 12f, and a part of the roller 16 is accommodated so as to protrude from the partition recess 12f and be retractable. At this time, the rotating shaft 16b faces the width direction, and the rotating shafts 16b of the five rollers 16 are parallel and equally spaced. For this reason, the five rollers 16 rotate along the longitudinal direction of the clip piece 12.

  The coil spring 18 is disposed at both ends of the roller 16 in the rotation axis direction. As shown in FIG. 4, one end of the coil spring 18 is fixed to the bottom surface of the partition recess 12f, and the other end is the rotation shaft. It is fixed to 16b. Here, since the coil spring 18 is housed in the partition recess 12f in a state of being contracted in the contact / separation direction, the roller 16 is always urged by the coil spring 18 in a direction protruding from the partition recess 12f. For this reason, in the clip piece 12 alone, as shown in FIG. 2B, a part of the roller 16 protrudes from the surface of the flat portion 12a.

  2 and 3, the cap 20 is a member that covers the slope portions 12 b and 12 b, and when the indirect hot-line tool grips the slope portions 12 b and 12 b, the indirect hot-line tool is inclined to the slope portions 12 b and 12 b. For example, a rubber member having irregularities formed on the surface is applicable.

  The rubber member 22 is an elastic member that is fixed to the end of the partition portion 12e facing the clip piece, that is, the top surface of the partition portion 12e.

  The pair of clip pieces 12 and 12 to which the magnet 14, the roller 16, the coil spring 18, the cap 20, and the rubber member 22 are attached are opposed to each other, and the opposed magnets 14 and 14 are attracted to each other. Thereby, as shown in FIG. 1, the electric wire clip 1 is comprised.

  FIG. 5 is a cross-sectional view showing the internal configuration of the electric wire clip 1 of the first embodiment. In the electric wire clip 1 in the normal state, as shown in FIG. 5, the surfaces of the magnets 14, 14 arranged in the region of the flat portion 12 a of the pair of clip pieces 12, 12 are attracted and abutted by magnetic force. ing. At this time, the surfaces of the magnets 14 and 14 arranged in the region of the slope portions 12b and 12b of the clip piece 12 face each other in a state of being separated from each other. In the normal state, the direction in which the flat portions 12a of the pair of clip pieces 12 and 12 face each other coincides with the contact / separation direction.

  Further, in the electric wire clip 1 in the normal state, the rollers 16 and 16 facing each other abut against each other and are positioned inside the recess 12d. At this time, since the coil spring 18 is in a contracted state, the roller 16 is urged by the coil spring 18 toward the 12 flat surface portions of the opposing clip pieces, and the rollers 16 fixed to the pair of clip pieces 12 and 12 are in contact with each other. Are in contact with each other while being pressed against each other. Further, in the normal state, the top surfaces of the partition portion 12e face each other, so that the rubber members 22 fixed to the pair of clip pieces 12 and 12 come into contact with each other.

  Next, the attachment operation of the electric wire clip 1 of 1st Embodiment is demonstrated, referring FIG. 6, FIG.

  6 is an explanatory view showing a state in which the electric wire clip 1 is sandwiched between the hot wire tools 50, and FIG. 7 is an explanatory view showing a state in which the electric wire clip 1 is further sandwiched between the hot wire tools 50 from the state of FIG. .

  First, the operator operates the hot wire tool 50 and, as shown in FIG. 6, the caps 20, 20 facing each other at one end portion of the both ends of the electric wire clip 1 are attached to the hot wire tool 50. The caps 20 and 20 are brought into contact with each other by holding the caps 20 and 20 with the live tool 50 as shown in FIG. At this time, the pair of clip pieces 12 rotate around the portion where the magnets 14 and 14 in the vicinity of the inclined surface portion 12b held by the live tool 50 are adsorbed, and the inclined surfaces facing each other at the other end portion. The parts 12b and 12b are separated. At this time, the magnets 14 and 14 in the vicinity of the slope portions 12b and 12b are arranged at a distance that can be attracted to each other.

  Further, the operator operates the hot wire tool 50 in this state to position the electric wire 100 between the caps 20 and 20 facing each other at the other end of the electric wire clip 1 as shown in FIG. Then push in the electric wire clip 1. When the electric wire 100 passes between the rollers 16, the roller 16 rotates.

  Thereby, the electric wire 100 moves to one end side, is positioned at a predetermined portion in the flat portion 12a of the pair of clip pieces 12, and is sandwiched by the four rollers 16 protruding from the flat portion 12a of the clip piece 12. . Furthermore, the wire clip 1 is such that the opposing magnets 14 and 14 are attracted at one end of the wire clip 1 and the opposing magnets 14 and 14 are separated from each other at the other end of the wire clip 1. Maintained at.

  Finally, the operator operates the hot wire tool 50 to remove the hot wire tool 50 from the electric wire clip 1. Thereby, the attachment work of the electric wire clip 1 is completed.

  In the state where the electric wire clip 1 is attached to the electric wire 100, the opposing magnets 14 and 14 are separated from each other at the other end of the electric wire clip 1, but an attractive force acts between the opposing magnets 14 and 14. Yes. For this reason, the attractive force between the magnets 14, 14 at the other end of the electric wire clip 1 acts on the electric wire 100 via the roller 16 and the rubber member 22. Thereby, the electric wire 100 is pinched by the clip body 10 and is reliably supported by the plurality of rollers 16 and the rubber member 22.

  In the mounting operation described above, the caps 20, 20 facing each other at one end of the both ends of the electric wire clip 1 are held by the holding portion 50 a of the hot wire tool 50. It is also possible to attach the electric wire clip 1 to the electric wire 100 by holding the caps 20, 20 facing each other at the other end with the holding portion 50 a of the hot wire tool 50.

  Further, in the above-described mounting operation, the operator operates the hot wire tool 50 and, as shown in FIG. 7, the caps 20, 20 facing each other at one end of the both ends of the electric wire clip 1. , And the magnets 14 and 14 at the other end are separated from each other. However, the present invention is not limited to this. For example, the operator operates the hot wire tool 50 to hold one end at both ends of the electric wire clip 1 so that the magnets 14 and 14 at the other end are not separated from each other, as shown in FIG. The electric wire clip 1 is pushed in after positioning the electric wire 100 between the caps 20 and 20 at the other end while the magnets 14 and 14 at the other end are adsorbed. At this time, the electric wire 100 moves while separating the magnets 14 and 14 and reaches between the flat portions 12a. After the electric wire 100 passes through the magnets 14 and 14, an attractive force acts on the electric wire 100 via the roller 16 between the magnets 14 and 14 at the other end of the electric wire clip 1. Thereby, the electric wire 100 is reliably clamped by the electric wire clip 1.

  In addition, the operator may operate the hot wire tool 50 to hold one end of both ends of the electric wire clip 1 so that the magnets 14 and 14 at the other end are slightly separated from each other. . Thereby, the electric wire 100 can be easily passed between the magnets 14 and 14.

  In particular, when the electric wire clip 1 is attached to the electric wire 100 at a right angle and the electric wire 100 is gripped by the four rollers 16, even if the electric wire clip 1 tries to rotate due to its own weight, the electric wire 100 has two rollers 16, It will be difficult to get over 16. For this reason, when the electric wire clip 1 is attached to the electric wire 100, the electric wire clip 1 can be maintained in a state in which the electric wire clip 1 is oriented in a direction perpendicular to the electric wire 100, and movement of the electric wire clip 1 on the electric wire 100 can be reduced. It becomes possible.

  When removing the electric wire clip 1 from the electric wire 100, the operator operates the hot wire tool 50 to hold one of the caps 20, 20 on both sides of the electric wire clip 1. Then, the worker operates the hot wire tool 50 to pull the end of the electric wire clip 1. As a result, the electric wire 100 moves on the plane portion 12 a while rotating the roller 16, and passes between the magnets 14 and 14. Thereby, the electric wire clip 1 is removed from the electric wire 100.

  In addition, when removing the electric wire clip 1 from the electric wire 100, the hot wire tool 50 is operated to hold the caps 20 and 20 on the side where the magnets 14 and 14 are attracted, or the magnets 14 and 14 are Whether or not to hold the caps 20 and 20 at the end on the separated side may be appropriately determined by the worker according to the work environment.

  As described above, according to the first embodiment of the present invention configured as described above, when the magnets 14 and 14 at both ends of the pair of clip pieces 12 and 12 are attracted to each other, the rollers 16 facing each other. , 16 are in contact with each other when the coil spring 18 is urged. Further, when the electric wire is sandwiched between the electric wire clips 1, the slope portions 12b and 12b facing each other at one end portion of the clip body 10 are closed by using an indirect hot wire tool so that the other end portion is opened. In other words, the electric wire can be inserted from the other end. And when an electric wire is inserted in the electric wire clip 1, an electric wire is hold | gripped by the roller 16 which is mutually biased by the coil spring 18. As shown in FIG. Furthermore, when the indirect hot wire tool is removed from the electric wire clip 1, the other end portion of the clip body 10 is closed in a direction in which the other end portion closes due to an attractive force acting between the magnets 14 and 14 facing each other. Force acts. Thereby, when the electric wire clip 1 is attached, the electric wire is gripped by the attracting force of the magnets 14 and 14 and the urging force of the coil spring 18, so that the electric wire clip 1 can be reliably attached to the electric wire.

  Further, when the electric wire clip 1 is attached to and detached from the electric wire, the electric wire clip 1 is pushed or pulled with respect to the electric wire, so that the electric wire is rotated by the roller 16 and the plane portions 12a facing each other are rotated. Move between. For this reason, it becomes possible to provide the electric wire clip 1 which can reduce the friction load of an electric wire and the plane part 12a, and can perform attachment and removal with respect to an electric wire smoothly.

  Moreover, according to 1st Embodiment, the rollers 16 and 16 come to oppose reliably by providing the roller 16 inside the recessed part 12d formed in the plane part 12a. For this reason, it is possible to reliably hold the electric wire by the roller 16 of the electric wire clip 1. Further, the roller 16 protrudes and retracts into the recess 12d while rotating when the wire clip is attached to and removed from the wire. Thereby, it becomes possible for an electric wire to move easily between the plane parts 12a which mutually oppose.

  Moreover, according to 1st Embodiment, since the rubber member 22 is provided on the top of the partition part 12e, an electric wire comes to be clamped with the two rubber members 22 and 22 with the rollers 16 and 16 now. The electric wire clip 1 can be securely attached to the electric wire.

In the state where the magnets 14 of the pair of clip pieces 12 and 12 are attracted, a slight gap is formed between the flat portions 12a facing each other. Are formed, and the rollers 16 and 16 facing each other are in contact with each other.

  Next, the mounting operation of the electric wire clip 1 of the second embodiment will be described with reference to FIG.

  FIG. 9 is an explanatory view showing a state where the electric wire clip 1 is sandwiched between the hot wire tools 50. First, the operator operates the hot wire tool 50 to grip the caps 20 and 20 facing each other at one end portion of the both ends of the electric wire clip 1 with the grip portion 50a of the hot wire tool 50, As shown in FIG. 9, the caps 20 are brought into contact with each other.

  At this time, the magnets 14 and 14 on the side of the live tool 50 attracted to each other are drawn into the recess 12h, and the surfaces of the magnets 14 and 14 are flush with a part of the flat surface portion 12a and the inclined surface portion 12b. In addition, the pair of clip pieces 12 rotate around the portion where the magnets 14 and 14 near the slope portion 12b on the side held by the live tool 50 are attracted, and the slope portions face each other at the other end. 12b and 12b are separated.

  Here, when the pair of clip pieces 12 are rotating, the other end of the electric wire clip 1 protrudes from the recess 12h while the magnets 14 and 14 are attracted to each other, but the other end is predetermined. The magnets 14 and 14 are separated when they are separated by a distance or more. Here, since the attracting force acts even after the magnets 14 and 14 are separated from each other, the magnet 14 is maintained in a state of protruding from the recess 12h.

  Then, the worker operates the hot wire tool 50 in this state to bring the caps 20, 20 facing each other at the other end of the electric wire clip 1 closer toward the electric wire 100. Furthermore, an operator pushes in the electric wire clip 1 after positioning the electric wire 100 between the caps 20 and 20 at the other end.

  Thereby, the electric wire 100 moves to one end side of the electric wire clip 1 while rotating the roller 16, and is positioned at a predetermined portion in the flat surface portion 12a of the pair of clip pieces 12, and the electric wire clip of the first embodiment. 1 is attached to the electric wire 100.

  Further, the worker removes the hot wire tool 50 from the electric wire clip 1. At this time, the magnets 14, 14 project from the recess 12 h at one end of the electric wire clip 1, so that the pair of clip pieces 12 are slightly rotated and the magnets 14, 14 are at the other end of the electric wire clip 1. Approach and adsorb to each other. Thereby, as shown in FIG. 10, the electric wire 100 is gripped by the electric wire clip 1.

  When removing the electric wire clip 1 from the electric wire 100, the operator operates the hot wire tool 50 to hold one of the caps 20, 20 on both sides of the electric wire clip 1. Then, the worker operates the hot wire tool 50 to pull the end of the electric wire clip 1. Thereby, the electric wire 100 moves the flat part 12a, rotating the roller 16, passes between the magnets 14 and 14, and the electric wire clip 1 is removed from the electric wire 100. FIG.

  As described above, according to the second embodiment of the present invention configured as described above, the same effect as that of the electric wire clip 1 of the first embodiment can be obtained, and one of the slope portions 12b and 12b that make a pair in the clip body 10 can be obtained. Is closed and the other slopes 12b and 12b are separated from each other, the magnets 14 and 14 in the vicinity of the other slopes 12b and 12b protrude from the plane part 12a, so that the other slopes 12b and 12b The distance between the magnets 14 and 14 facing each other on the side is shortened. Thereby, since the attractive force between the magnets 14 and 14 acts strongly, it becomes possible to urge in the direction which closes the other slope part 12b and 12b side which is spaced apart. Thereby, it becomes possible to hold | grip the electric wire 100 reliably.

  In the second embodiment of the present invention, the clip 12 is formed with the recesses 12h and 12h, and the slider 40 is slid inside the recesses 12h and 12h. If it is the structure to project, it will not be restricted to said structure. For example, instead of the recesses 12h and 12h, grooves extending in the contact / separation direction are formed on the side surfaces of both ends in the longitudinal direction of the flat surface portion 12a of the clip piece 12, and the side plate portions 40a and 40a of the slider 40 are placed inside the grooves. The slider 40 may be slid and moved by positioning and sliding the side plate portions 40a and 40a of the slider 40 outside the clip piece 12.
