Description

  The present invention relates to a fixture for fixing an IC tag to an electric wire.

  Conventionally, a system is known in which an IC tag is attached to an electric wire of a wiring facility, and the type of the electric wire, maintenance information, and the like are determined based on identification information transmitted from the IC tag (see, for example, Patent Documents 1 and 2). ). When constructing such a system, it is desirable that the IC tag can be stably fixed to the electric wire as well as the work load does not increase even if the number of installed IC tags increases due to the scale of the wiring equipment.

  By the way, as a technique for fixing the IC tag to an object, a technique for fixing via a band (for example, see Patent Document 3), a technique for fixing by an adhesive tape (for example, see Patent Document 4), and a technique for fixing via a clip. Various forms such as (see, for example, Patent Document 5) are known. Therefore, it is conceivable to apply these techniques to the use for fixing the IC tag to the electric wire.

JP 2004-38583 A JP 2001-69625 A JP 2004-112886 A JP 2007-328378 A JP 2002-140669 A

  However, for example, when the technique of Patent Document 3 is adopted, a complicated operation of winding and fastening a band around an electric wire is required. Moreover, when employ | adopting the technique of patent document 4, a problem may arise in durability from a material surface. Furthermore, when the technique of Patent Document 5 is adopted, it is necessary to widen the opening when the clip is attached to the electric wire, which requires a relatively large force. In that case, in order to improve the ease of insertion of the electric wire, it is conceivable to project a guide portion that expands in a tapered shape at the opening of the clip. However, when such a guide part is provided, workability when the clip is assembled to the electric wire is enhanced, but it is assumed that the guide part becomes an obstacle after the assembly. For example, when a plurality of electric wires are arranged in parallel, there is a possibility that a space problem may occur due to interference of the guide portion with an adjacent electric wire. For this reason, there is room for improvement no matter which fixing technique is adopted.

  This invention is made | formed in view of such a subject, The objective is what was excellent in the workability | operativity at the time of assembling to an electric wire, and the installation property after an assembly | attachment as a fixing tool for installing an IC tag in an electric wire. Is to provide.

  In order to solve the above problems, an IC tag fixture according to an aspect of the present invention is a fixture for installing an IC tag on an electric wire, and is made of a resin material and has a cylindrical shape having a C-shaped cross section. Main body, an opening for introducing an electric wire, and a support portion which is provided at a position different from the opening of the main body and can support an IC tag. And comprising. The opening is formed at a middle portion in the longitudinal direction of the main body and receives a first notch for receiving the electric wire so as to cross the main body, and a second notch extending from the first notch to one end of the main body. A notch and a third notch extending from the first notch to the other end of the main body, the opening positions in the circumferential direction of the main body being the second notch and the third notch And are different from each other.

  According to this aspect, the fixing tool can be assembled to the electric wire by a simple operation of attaching the main body obliquely to the electric wire via the first notch and rotating the main body in a direction parallel to the electric wire. it can. That is, by rotating the main body to the side where the second notch and the third notch are opened, a reaction force from the electric wire can be applied to the opening edge opposite to the rotation direction of the main body. it can. As a result, the opening of the main body is expanded at the positions of the second notch and the third notch. The electric wires can be introduced into the inside of the main body through the opening thus opened, and both can be assembled. In addition, since the first cutout portion functions as a guide when the wire is attached to the electric wire, it is not necessary to project the guide portion at the opening of the main body. That is, the interference part to the outside after assembling the fixing tool to the electric wire can be reduced, and an excellent installation property can be obtained.

  ADVANTAGE OF THE INVENTION According to this invention, what was excellent in the workability | operativity at the time of assembling | attaching to an electric wire and the installation property after an assembly | attachment can be provided as a fixing tool for installing an IC tag in an electric wire.

  The fixture according to the embodiment is made of a resin material, has a cylindrical main body having a C-shaped cross section, and is formed so as to open a side portion from one end to the other end of the main body, and an opening for introducing an electric wire And a support portion provided at a position different from the opening of the main body and capable of supporting the IC tag. The opening is formed at a middle portion in the longitudinal direction of the main body and receives a first notch for receiving the electric wire so as to cross the main body, and a second notch extending from the first notch to one end of the main body. A notch and a third notch extending from the first notch to the other end of the main body, the opening positions in the circumferential direction of the main body being the second notch and the third notch And different from each other.

  The “main body” may be made of a resin material so that the opening can be elastically deformed in the expanding direction by applying a certain load or more. The first notch portion may have a concave profile formed by the opening edges facing each other when viewed in the axial direction of the received electric wire. In that case, it is preferable that the profile is a shape along the side surface of the electric wire, such as an arc shape, from the viewpoint of stability when the fixture is attached to the electric wire. The second cutout portion and the third cutout portion extend in opposite directions from the first cutout portion, and an opening portion extending from one end of the main body to the other end is formed by these cutout portions. The second cutout portion and the third cutout portion may be opened so as to be biased toward the opposite sides with respect to the axis of the main body when the first cutout portion is viewed in a plan view. Furthermore, the second notch and the third notch are defined with respect to the center of the main body (center of the first notch) when the first notch is viewed in plan view. You may form in the position used as point symmetry.

  According to this aspect, the main body is placed obliquely on the electric wire at the position of the first notch, and then the main body is rotated in a direction parallel to the electric wire, so that the opening of the main body becomes the second A force due to a rotational moment is applied to the electric wire at the position of the notch and the third notch. As a result, the opening of the main body receives the reaction force from the electric wire, and elastically deforms in the direction in which each of the second notch and the third notch is expanded. Thereby, the electric wire can be easily guided to the inside of the main body by utilizing the state in which the opening is expanded. That is, the main body can be easily attached to the electric wire by rotating around the first notch.

  Specifically, the first cutout portion includes, on each of the opening edges facing along the longitudinal direction, a top portion serving as an introduction end in the receiving direction of the electric wire, a bottom portion for receiving the electric wire, and a top portion and a bottom portion. And a connecting portion connecting the two. And the depth of the bottom part on the basis of a top part is set so that it may be accepted in the main part beyond the half direction of the diameter of an electric wire. In the second notch, one of the opposed opening edges is connected to the bottom of one opening edge of the first notch, and the other is on the top of the other opening edge of the first notch. The distance between the opening edges facing each other is smaller than the diameter of the electric wire. In the third notch, one of the opposed opening edges is connected to the top of one opening edge of the first notch, and the other is on the bottom of the other opening edge of the first notch. The distance between the opening edges facing each other is smaller than the diameter of the electric wire.

  The “opening edge facing the notch” here forms an opening in the main body. The position where the second notch and the third notch form the opening is different in the circumferential direction of the main body. The “bottom portion of the first notch” corresponds to a portion that locks the electric wire in the receiving direction, that is, a portion that is located at the innermost position in the insertion direction when the electric wire is inserted. The “top portion of the first cutout portion” is a portion constituting the tip of the receiving port into which the electric wire is introduced, and corresponds to a portion of the first cutout portion that is farthest from the bottom in the electric wire insertion direction.

  According to this aspect, when the fixing tool is attached to the electric wire, half or more in the radial direction of the electric wire can be received in the first cutout portion at the stage of placing the main body on the electric wire. That is, when the main body is rotated, the contact point with the electric wire that becomes the base point of elastic deformation can be set to a position beyond the maximum diameter portion of the electric wire. As a result, the force acting on the electric wire from the main body can be directed to the inside of the main body. That is, the electric wire can be autonomously accommodated by the operation of rotating the main body, and the workability of attaching the fixture to the electric wire is improved.

  Further, when the main body is viewed in the axial direction, a straight line connecting the opening edge of the second notch portion extending from one bottom portion of the first notch portion and the axis line on the projection plane perpendicular to the axial direction; The angle formed by the straight line connecting the opening edge of the third cutout portion extending from the other bottom portion of the first cutout portion and the axis may be configured to be smaller than 180 degrees.

  According to this aspect, when the fixture is attached to the electric wire, when the fixture is placed on the electric wire at the position of the first notch, the insertion depth in the radial direction with respect to the main body of the electric wire is larger than the radius. Can be bigger. That is, at the stage of attaching the main body to the electric wire, more than half of the electric wire in the radial direction can be received in the first notch. As a result, as described above, the workability of attaching the fixture to the electric wire is improved.

  The second cutout portion may be formed such that an opening edge extending from one bottom portion of the first cutout portion toward one end of the main body is parallel to the axis of the main body. Similarly, the 3rd notch part may be formed so that the opening edge extended toward the other end of a main body from the other bottom part of a 1st notch part may become parallel to the axis line of a main body.

  According to this aspect, the one opening edge of the second notch and the other opening edge of the third notch can be arranged on the same plane passing through the bottom of the first notch. Therefore, when the main body is rotated, the opening edge is not uneven, the main body can be rotated smoothly, and workability when the fixing tool is attached to the electric wire is improved. On the other hand, the height of the opening edge is maximized in such a range that does not become an obstacle. For this reason, after a main body is assembled | attached to an electric wire, required rigidity can be ensured in the position of a 2nd notch part and a 3rd notch part, and the holding power of the fixing tool in an electric wire can be made high. .

From this state, the IC tag 2 can be attached to the hook portion 12. Alternatively, the IC tag 2 may be attached to the hook portion 12 in advance, and the clip 1 to which the IC tag 2 is fixed may be attached to the cable 3.

FIG. 3 is an explanatory diagram showing the configuration of the clip. (A) is a plan view, (B) is a left side view, (C) is a front view, (D) is a right side view, (E) is a bottom view, and (F) is an arrow AA view of (C). Cross-sectional views are shown respectively.
The clip 1 is obtained by integrally forming the main body 10 and the hook portion 12 by resin injection molding. Although the main body 10 has a cylindrical shape as a whole, the main body 10 has a C-shaped cross section over its entire length by providing an opening 14 opened in the longitudinal direction along the side surface. A hook 12 is provided on one side of the main body 10 and an opening 14 is provided on the opposite side.

  The hook portion 12 includes a pair of side wall portions 16 extending in the longitudinal direction of the main body 10, a locking portion 18 that bridges a longitudinal intermediate portion of the pair of side wall portions 16 in the circumferential direction, and extends forward from the locking portion 18. It has a locking piece 20. A rectangular parallelepiped housing space is formed by the opposing surfaces of the pair of side wall portions 16, and a flat mounting surface 22 is formed on the bottom thereof so as to project to the opposing side. The locking piece 20 has a claw portion 24 that extends in parallel between the pair of side wall portions 16 and protrudes to the mounting surface 22 side (the outer peripheral surface side of the main body 10) at the tip thereof. The IC tag 2 of the present embodiment has a rectangular plate shape, is inserted from the front of the hook portion 12, and is pushed along the placement surface 22 while elastically deforming the claw portion 24 outward. The IC tag 2 is supported so as to be sandwiched between the claw portion 24 and the locking portion 18 that have been elastically restored when the IC tag 2 is pushed beyond the claw portion 24.

  The opening 14 includes a notch 31 (corresponding to a “first notch”) formed in the longitudinal center of the main body 10, and a notch 32 (extending from the notch 31 to one end of the main body 10. And a notch 33 (corresponding to a “third notch”) extending from the notch 31 to the other end of the main body 10. That is, the opening 14 extending from one end of the main body 10 to the other end is formed by the notches 31, 32, 33.

  FIG. 4 is an explanatory diagram showing a specific configuration of the clip. (A) is a front view, (B) is a left side view as seen obliquely from the front, and (C) is a bottom view. 4 virtually shows a state in which the main body 10 is put on the set position of the cable 3 when the clip 1 is attached to the cable 3, and a two-dot chain line in the drawing indicates the cable 3. FIG. 4B shows a state in which the main body 10 is placed in the cable 3 and viewed in the axial direction of the cable 3.

  When attaching the clip 1 to the cable 3, as shown in the drawing, the clip 1 is placed obliquely with respect to the cable 3, and the clip 1 is attached so as to rotate on the cable 3 from this state. The clip 1 has a shape suitable for such an attachment method.

  That is, as shown in FIG. 4B, when the main body 10 is viewed from the axial direction of the cable 3, the cutout portion 31 serving as a receiving portion of the cable 3 has an arc shape along the outer shape of the cable 3. . That is, the notch 31 forms a semicircular projection shape by one of the opposing opening edges (opening edge 31a) and the other (opening edge 31b), and the setting position of the cable 3 is set along the shape. accept. As shown in FIG. 4C, when the main body 10 is placed on the cable 3, the main body 10 and the cable 3 cross each other at an angle. As a result, as shown in FIG. 4B, when viewed from the axial direction of the cable 3 introduced into the main body 10, the clip 1 opens downward and the cable 3 extends between the introduction end 31c and the introduction end 31d. And has a shape having bottom portions 34 and 35 above.

  Returning to FIG. 3, the notch 31 is provided so as to extend obliquely with respect to the longitudinal direction of the main body 10. As shown in FIG. 3 (F), the opening edge 31a of the notch 31 has a bottom 34 connected with the shortest circumferential length from the hook portion 12 on the left side in the drawing, and the longest circumference on the hook portion 12 on the right side in the drawing. It becomes the top part (introduction end 31c shown in FIG. 4) connected by length. Thus, as can be seen from the fact that the positions of the opening edge 31a are shifted on the right side and the left side in the figure, the top and bottom of the opening edge 31a are positioned so as to be shifted in the circumferential direction of the main body 10. Yes. Similarly, both the top and bottom of the opening edge 31 b are positioned so as to be displaced in the circumferential direction of the main body 10.

  In addition, one of the opposed opening edges (opening edge 32 a) of the notch 32 extends from the bottom 34 of the one opening edge 31 a of the notch 31 toward one end of the main body 10. On the other hand, one of the opening edges (opening edge 33 a) of the notch 33 extends from the bottom 35 of the other opening edge 31 b of the notch 31 toward the other end of the main body 10. As a result, as shown in FIG. 3E, the circumferential opening positions (opening ranges) of the notch 32 and the notch 33 in the main body 10 are different from each other (the center position of the circumferential opening range). Are different from each other). Specifically, the gap between the opening edge 32 a and the opening edge 32 b of the notch 32 and the gap between the opening edge 33 a and the opening edge 33 b of the notch 33 are on the axis L viewed from the bottom surface side of the main body 10. It is located on the opposite side. Furthermore, the gap between the notch 32 and the notch 33 is provided at a position that is point-symmetric with respect to the center O when the notch 31 is viewed in plan view. Further, the opening edge 32a and the opening edge 33a each extend in parallel with the axis L of the main body 10 and have a structure for improving workability for assembling the main body 10 to the cable 3. The description will be given later.

  More specifically, as shown in FIG. 4 (A), the substantial side (of the angle between the straight line l1 connecting the axis c1 of the main body 10 and the opening edge 32a and the straight line l2 connecting the axis c1 and the opening edge 33a ( The angle θ1 on the side on which the main body 10 is formed is configured to be smaller than 180 degrees (170 degrees in this embodiment). As shown in FIG. 4C, the angle θ2 formed by the axis c1 of the main body 10 and the axis c2 of the cable 3 is set to 45 degrees.

  Here, in the notch 31, the introduction end 31 c that is also a connection point with the opening edge 33 b corresponds to “one top of the notch”, and the introduction end 31 d that is also a connection point with the opening edge 32 b Corresponds to “the other top of the notch”. The semicircular shape described above is formed by the connecting portion that connects the introduction end 31 c and the bottom portion 34 and the connecting portion that connects the introduction end 31 d and the bottom portion 35. On the other hand, as shown in FIG. 4A, the distance w2 between the opening edges 32a and 32b facing each other in the notch 32 and the distance w3 between the opening edges 33a and 33b facing each other in the notch 33 are both cables. 3 to be smaller than the diameter d of 3. On the other hand, as shown in FIG. 4B, the width w1 of the introduction end of the cable 3 in the notch 31 is slightly larger than the diameter d of the cable 3, and it extends to the bottom with reference to the introduction end of the notch 31. The depth h is set to be slightly larger than the radius r of the cable 3.

  As a result, when the main body 10 is put on the cable 3 through the notch 31, the cable 3 is introduced until it abuts against the bottom portions 34 and 35 of the notch 31, and the axis c <b> 2 is inward of the main body 10. Come to be located. That is, at the stage where the clip 1 is put on the cable 3, more than half of the radial direction of the cable 3 can be received by the notch 31. In other words, the opening edges 32 b and 33 b of the main body 10 can be overhanged to a position exceeding the position of the maximum diameter (diameter) of the cable 3. Such a shape has a structure that improves workability for assembling the main body 10 to the cable 3, which will be described later.

Next, a method for fixing the clip 1 to the cable 3 will be described.
5-7 is explanatory drawing which shows the fixing method to the cable of a clip. FIG. 5 shows the plan view, FIG. 6 shows the side view, and FIG. 7 shows the bottom view. In each figure, (A) shows a state where the clip is put on the cable, (B) shows a state in the middle of attaching the clip to the cable by rotating the clip, and (C) shows that the clip has been fixed to the cable. Indicates the state.

  When the clip 1 is fixed to the cable 3, first, the clip 1 is placed on the set position of the cable 3 as shown in FIG. At this time, as shown in FIGS. 6A and 7A, the main body 10 is mounted so as to receive the cable 3 at the notch 31, and the main body 10 is inclined with respect to the notch 31. Placed. Further, as described above, the opening edges 32 b and 33 b of the main body 10 are overhanged to a position exceeding the position of the maximum diameter (diameter) of the cable 3.

  Subsequently, as shown in FIG. 5B, the clip 1 is applied with a fingertip in the normal direction as indicated by an arrow in the drawing until the main body 10 becomes parallel to the cable 3 (the axis of the main body 10 is connected to the cable). Rotate until it is parallel to the 3 axis. At this time, the opening edges 32 b and 33 b of the main body 10 act to apply a load that presses the side surface of the cable 3 at the contact position with the cable 3. Therefore, as shown in FIGS. 6B and 7B, the opening edges 32b and 33b receive a reaction force from the side surface of the cable 3 (see the solid line arrow), and the notch 32 and the notch A force in the expanding direction acts on the portion 33 (see a two-dot chain line arrow). As a result, the main body 10 is elastically deformed so as to expand the opening 14 at the positions of the notch 32 and the notch 33. At that time, since the contact position between the opening edges 32 b and 33 b and the cable 3 is beyond the position of the maximum diameter (diameter) of the cable 3, the cable 3 is pulled into the inside of the main body 10. A force acts (see the dashed line arrow). For this reason, the operation of rotating the clip 1 allows the main body 10 to introduce the cable 3 autonomously without particularly pressing the clip 1 against the cable 3.

  In this way, the clip 1 is fixed to the cable 3 at the same time as the main body 10 is rotated to a position parallel to the cable 3 as shown in FIG. At this time, as shown in FIGS. 6C and 7C, the main body 10 returns from the elastically deformed state. However, since the outer diameter of the cable 3 is slightly larger than the inner diameter of the main body 10, for example, as can be seen from a comparison between FIG. 4A and FIG. An appropriate tightening force acts at the position of the notch 33. For this reason, the clip 1 is stably fixed to the cable 3. That is, the IC tag 2 is stably fixed to the cable 3 via the clip 1. Further, in this embodiment, as shown in FIG. 6C, in the state where the clip 1 is fixed to the cable 3, the guide protrusions that are often seen in the prior art are not provided in the opening. For this reason, when installing the clip 1, it is possible to suppress interference with surrounding parts.

[Second Embodiment]
Next, the fixture according to the second embodiment will be described. Note that the fixture of this embodiment is almost the same as that of the first embodiment except that the configuration of the opening (notch) is different. For this reason, the same components as those in the first embodiment are denoted by the same reference numerals and the description thereof is omitted.
FIG. 8 is an explanatory diagram illustrating the configuration of the clip according to the second embodiment. (A) is a plan view, (B) is a left side view, (C) is a front view, (D) is a right side view, (E) is a bottom view, and (F) is an arrow AA view of (C). Cross-sectional views are shown respectively.
The clip 201 is a fixture for installing the IC tag 2 on an electric wire of a wiring facility, and is obtained by integrally forming the main body 210 and the hook portion 12 by resin injection molding. That is, the clip 201 has the same hook portion 12 as that of the first embodiment as a support portion, but the shape of the main body 210 is different from that of the main body 10 of the first embodiment.

  That is, the main body 210 has an opening 214 extending from one end to the other end on one side thereof. The opening 214 includes a notch 231 (first notch) formed in the longitudinal center of the main body 210 and a notch 232 (second notch) extending from the notch 231 to one end of the main body 210. Part) and a notch 233 (third notch) extending from the notch 231 to the other end of the main body 210. One opening edge 232 a of the notch 232 extends from the bottom 34 of one opening edge 231 a of the notch 231 toward one end of the main body 210. On the other hand, one opening edge 233 a of the notch 233 extends from the bottom 35 of the other opening edge 231 b of the notch 231 toward the other end of the main body 210.

  The gap between the opening edge 232a and the opening edge 32b of the notch 232 and the gap between the opening edge 233a and the opening edge 33b of the notch 233 are relative to the axis L viewed from the bottom side of the main body 210. Is located on the opposite side. However, the gap between the notches is smaller than that of the first embodiment, and the opening width of the opening 214 is smaller than that of the opening 14.

FIG. 9 is an explanatory diagram showing a specific configuration of the clip and a fixing method to the cable. (A)-(C) have shown the state which put the clip on the cable, and (D)-(F) has shown the state which fixing to the cable of a clip was completed.
When fixing the clip 201 to the cable 3, first, as shown in FIGS. 9A to 9C, the clip 201 is mounted so as to be put on the set position of the cable 3. At this time, the main body 210 is mounted so as to receive the cable 3 at the notch 231, and the main body 210 is placed obliquely with respect to the notch 231. However, in this embodiment, as shown in FIG. 9B, the width of the opening end of the notch 231 is smaller than the diameter of the cable 3, and the depth is based on the opening end of the bottom of the notch 231. Is set to be smaller than the radius of the cable 3. As a result, when the main body 210 is placed on the cable 3 via the notch 231, the cable 3 abuts against the bottoms 34 and 35 of the notch 231 as shown in the figure, but the radial direction of the cable 3 More than half of the cutouts 31 are not accepted.

  Subsequently, from this state, the clip 201 is rotated around its normal line as shown by an arrow in the drawing until the main body 210 is parallel to the cable 3. At this time, the opening edges 32 b and 33 b of the main body 210 act to apply a load that presses the side surface of the cable 3 at the contact position with the cable 3. Therefore, the opening edges 32b and 33b receive a reaction force from the side surface of the cable 3, but the contact position between the opening edges 32b and 33b and the cable 3 is on the near side of the position of the maximum diameter (diameter) of the cable 3. The cable 3 is subjected to a force that is pushed out of the main body 210.

  Therefore, in order to draw the cable 3 into the main body 210 in the configuration of the present embodiment, an operator needs to press the clip 201 toward the cable 3 side. By rotating the main body 210 while applying such a pressing force, a force in the expanding direction is applied to the notch portion 232 and the notch portion 233, and the cable 3 can be introduced to the inside of the main body 210. .

  In this way, the clip 201 is fixed to the cable 3 as shown in FIGS. At this time, since the outer diameter of the cable 3 is slightly larger than the inner diameter of the main body 210 also in this embodiment, an appropriate tightening force acts on the cable 3 at the positions of the notch 232 and the notch 233. For this reason, the clip 201 and thus the IC tag 2 are stably fixed to the cable 3.

  As described above, in this embodiment, since the opening width and depth of the notch portion 231 are reduced, it is difficult to fix the cable 3 by simply rotating the clip 201 as in the first embodiment. However, when the clip 201 is rotated while applying a certain pressing force, a force due to the rotational moment acts in the direction of expanding the opening 214. Therefore, the working efficiency is improved rather than pushing the cable 3 into the clip 201 without such rotation. In other words, as in the first embodiment, the clip 1 can be assembled to the cable 3 with a low load by setting the opening width and depth of the notch in the center appropriately large, and the work efficiency is remarkable. Can be improved.

  The present invention is not limited to the above-described embodiments, and various modifications such as design changes can be added to the embodiments based on the knowledge of those skilled in the art. Embodiments described may also be included within the scope of the present invention.

  In the first embodiment, as shown in FIG. 4B, an example in which the depth h of the notch 31 is slightly larger than the radius r of the cable 3 is shown. In the modification, the depth h may be the same as the radius r of the cable 3. Alternatively, the depth h may be considerably larger than the radius of the cable 3. Since the notch 31 is configured to penetrate the main body 10 obliquely, the depth h has a degree of freedom in design. However, if the depth h is increased more than necessary, the rigidity of the main body 10 is reduced, and therefore, the clip is set within a range in which the durability of the clip can be sufficiently secured.

  In each of the embodiments, the notch portion in the middle portion in the longitudinal direction of the main body is configured to intersect at an angle of about 45 degrees with respect to the axis of the main body, but other angles such as about 30 degrees or 60 degrees are used. You may comprise so that it may cross. Moreover, in each Example, although the notch part was formed in semicircle shape, you may form in rectangular shape and other shapes. Also in that case, it is preferable that the above-mentioned depth h is not less than the radius of the cable 3.

  In each example, the clip was formed by resin injection molding. In a modification, each part may be formed by cutting a cylindrical resin material. The hook portion may be manufactured separately from the main body and later assembled to the main body.
