Description

  According to the present invention, a pair of half magnetic bodies having a shape obtained by dividing a cylindrical body into two along the axial direction is combined with each of the half magnetic bodies as the cylindrical body, and the axis of the cylindrical body It is related with the holding tool hold | maintained in the state by which the electric wire was inserted in the through-hole along.

  Conventionally, as a device that absorbs noise flowing in an electric wire, a pair of ferrite cores, which are half-divided magnetic bodies obtained by dividing a cylindrical body into two along the axial direction, are externally fitted around the electric wire and flow into the electric wire by the ferrite core. Ferrite clamps that absorb noise current are known. As this ferrite clamp, a pair of plastic cases that individually hold each ferrite core is connected by a hinge, and the pair of cases are closed to hold each ferrite core in a position where it is combined as the cylindrical body. There is something.

  Many ferrite clamps of this type are equipped with a lock mechanism that holds a pair of cases closed. To prevent the lock mechanism from coming off, a binding band is further attached to the peripheral surface of the closed ferrite clamp. May be wound and tightened (see, for example, Patent Document 1).

JP 2012-99707 A

  However, in the case of a binding band using a ratchet, for example, the length of the inner circumference of the ring formed by the binding band can be adjusted only to a discontinuous value, for example, for each tooth of the ratchet. For this reason, there has been room for improvement in strength for fastening the ferrite clamp or the ferrite core (half magnetic material). Further, even if a binding band whose length of the inner circumference of the ring can be arbitrarily adjusted is used, the ferrite clamp or the ferrite core (stronger than the case where the binding band is simply wound and tightened) You may want to tighten a half magnetic body.

  The technology described below is intended to solve the above-described problems, and one of its purposes is a pair of half-split magnetic bodies or a pair of cases holding the half-split magnetic bodies individually. An object of the present invention is to provide a holder that can be tightened with good strength.

  The holder described below includes a pair of halved magnetic bodies having a shape obtained by dividing a cylindrical body into two along the axial direction, and each of the halved magnetic bodies is combined as the cylindrical body. A holder for holding an electric wire inserted in a through hole along the axis of the cylindrical body, and the peripheral surface of the cylindrical body or each of the halved magnetic bodies is combined as the cylindrical body A pair of belts for fastening the pair of half magnetic bodies or the pair of cases, and an opening of the through hole. An engaging portion that engages with the electric wire protruding from the opening at the facing position; and a connecting portion that connects the band and the engaging portion; and the connecting portion is connected to the band. From the center of the part, when the engaging part is engaged with the electric wire, the electric wire Direction leading to a position where the mind is disposed is in a natural state where an external force to the holder is not acting, and wherein the intersecting at an angle different from that of the 90 ° to the longitudinal direction of the band body.

  In the holder configured in this way, the circumferential surface of the cylindrical body formed by combining a pair of half magnetic bodies, or each half magnetic body so that each half magnetic body is combined as a cylindrical body. A belt is wound around the peripheral surfaces of the pair of cases held in the box. The belt body fastens the pair of half magnetic bodies or the pair of cases. Moreover, an engaging part engages with the electric wire which protruded from the said opening part in the position facing the opening part of the through-hole of the said cylindrical body.

  And the said band and the said engaging part are connected via the connection part. The direction from the center of the portion where the connecting portion is connected to the belt body to the position where the center of the electric wire is disposed with respect to the engaging portion when the engaging portion is engaged with the electric wire In a natural state where no external force is applied to the device, it intersects at an angle different from 90 ° with respect to the longitudinal direction of the band. For this reason, the angle is different from 90 ° when the belt is wound around the cylindrical body or the peripheral surface of the case and the engaging portion is engaged with the electric wire (hereinafter referred to as a mounted state). As a result, the belt body is twisted. This twist reduces the inner circumference of the ring formed by the band, and improves the strength with which the band clamps the peripheral surface of the cylindrical body or the case. Therefore, when this holder is used, a pair of half magnetic bodies or a pair of cases each holding the half magnetic bodies can be tightened with good strength.

  The angle may be any angle between 75 ° and 85 °. When the angle is 75 ° or more (less than 90 °), the mounting work of the holder is easier. Moreover, the effect by the said twist will appear favorably that the said angle is 85 degrees or less. Therefore, in this case, the workability of the mounting work can be further improved, and the pair of half magnetic bodies or the pair of cases holding the half magnetic bodies individually can be tightened with better strength. . In addition, these angles do not have critical significance, but are angles shown as approximate guidelines.

  In addition, the connecting portion and the belt are configured in a long plate shape, and when the connecting portion and the belt are developed in a planar shape, even if the plate thickness direction of the connecting portion and the belt is aligned. Good. In that case, the force that causes the twist in the mounted state acts along the surface of the plate-like member (that is, along the direction in which the bending rigidity is large), and the twist can be generated more satisfactorily. . Therefore, in this case, the pair of half magnetic bodies or the pair of cases individually holding the half magnetic bodies can be tightened with better strength.

  Further, a pair of the engaging portions are provided corresponding to the opening portions of the through holes, and the connecting portion is a series of connecting the one engaging portion, the belt body and the other engaging portion sequentially. You may be comprised by the elongate plate-shaped member. In that case, a pair of engaging portions are disposed on both end sides of the through hole of the cylindrical body, and in the mounted state, connecting portions are disposed so as to connect the pair of engaging portions. For this reason, the force which produces the said twist in the said mounting state generate | occur | produces more favorably. Therefore, in this case, the pair of half magnetic bodies or the pair of cases individually holding the half magnetic bodies can be tightened with better strength.

  In addition, when a pair of engaging portions are provided in this way, when a pair of engaging portions are engaged with the electric wires, a line connecting the positions where the centers of the electric wires are disposed with respect to the engaging portions. Even if it intersects at an angle different from 90 ° with respect to the longitudinal direction of the strip in a natural state where no external force is applied to the holder, the strip is similarly twisted. For this reason, a pair of halved magnetic bodies or a pair of cases holding the halved magnetic bodies individually can be tightened with good strength even in the following holders.

  That is, a pair of half magnetic bodies having a shape obtained by dividing the cylindrical body into two along the axial direction are combined with each of the half magnetic bodies as the cylindrical body, and along the axis of the cylindrical body. A holder that holds the electric wire inserted into the through-hole, and the circumferential surface of the cylindrical body, or the half magnetic bodies so that the half magnetic bodies are combined as the cylindrical body. Wound around the peripheral surfaces of a pair of cases holding the bodies individually, at a position opposite to the pair of half magnetic bodies or the band body for fastening the pair of cases, and the pair of openings of the through holes, A pair of engaging portions that respectively engage with the electric wires protruding from the openings, and a connecting portion that sequentially connects the one engaging portion, the belt body, and the other engaging portion; When the engaging portions are engaged with the electric wires, the center of the electric wires is arranged with respect to the engaging portions. In the natural state in which an external force does not act on the holder, the line connecting the positions to be cut intersects with the longitudinal direction of the band at an angle different from 90 °. The effect of.

  Moreover, the said engaging part may be wound and fixed to the said electric wire. In that case, the position of the said cylindrical body is also positioned in the predetermined position on an electric wire by fixing an engaging part to an electric wire. Therefore, the absorption of noise current by the cylindrical body formed by combining a pair of halved magnetic bodies is performed more satisfactorily.

  Next, an embodiment of the present invention will be described with an example. In the following description, the side that contacts the ferrite clamp 90 when mounted on the ferrite clamp 90 (see FIGS. 3, 5, 7, 11, and 13) is referred to as the upper side. In addition, a direction in which the ferrite clamp 90 is disposed along the central axis when the ferrite clamp 90 is mounted is a front-rear direction. However, each of these directions is only a direction defined in order to briefly explain the relative positional relationship between the respective parts constituting the holder. When actually using the holder, the direction in which the holder is oriented is arbitrary. For example, the vertical direction shown in the figure is used in a state where the vertical direction does not match the gravity. It doesn't matter.

[First Embodiment]
A holder 10 shown in FIGS. 1A to 1F includes a belt body 11, engagement portions 13 and 14 disposed before and after the belt body 11, engagement portions 13, the belt body 11, And a connecting portion 15 that sequentially connects the engaging portions 14 and is integrally formed of synthetic resin. In the present embodiment, the belt body 11, the engaging portion 13, and the engaging portion 14 are all configured as a binding band.

  That is, the engaging part 14 is configured in a band shape. Then, as shown in FIGS. 2A and 1 as a cross-sectional view taken along line AA in FIG. 1C, the length of the engaging portion 14 extends from the vicinity of the center to the vicinity of the tip 14S (the left end in FIG. 1). A plurality of teeth 14A are arranged on the upper surface side along the direction. A buckle 14B that locks the teeth 14A is provided at the base end 14K (the right end in FIG. 2A) of the engaging portion 14. The buckle 14B is formed with a hole 14C through which the tip 14S can penetrate in the vertical direction. A claw 14D that engages with the teeth 14A when the tip 14S is inserted into the hole 14C from below is formed in the lower portion of the inner wall surface of the hole 14C.

  The claw 14D is configured to be elastically deformable. Further, the contact surface of the claw 14D with the tooth 14A is inclined so that the opening diameter of the hole 14C becomes wider toward the lower side. For this reason, when the tip 14S is inserted into the hole 14C of the buckle 14B from below, the claw 14D allows the teeth 14A to get over when the engaging portion 14 is pushed into the hole 14C from below to above. For this reason, the diameter of the ring including the engaging portion 14 in which the tip 14S is inserted into the hole 14C can be reduced by pulling the tip 14S. On the other hand, the claw 14D engages and suppresses the teeth 14A when the engaging portion 14 is about to be pulled out from the hole 14C from the upper side to the lower side. For this reason, after the diameter of the ring formed of the engaging portion 14 is reduced as described above, the increase in the diameter is suppressed. As shown in FIG. 1, the engaging portion 13 includes teeth 13 </ b> A and a buckle 13 </ b> B, and is configured similarly to the engaging portion 14.

  As shown in the cross-sectional view along the line BB in FIG. 2B, the belt body 11 is configured in the same manner. However, the buckle 11 </ b> B of the band body 11 has a hole 11 </ b> C into which the tip 11 </ b> S of the band body 11 can be inserted along the lower surface of the band body 11. When the tip 11S is inserted into the hole 11C of the buckle 11B from the base end 11K side, the band 11 forms a ring, and the claw 11D formed inside the hole 11C reduces the diameter of the ring. While suppressing the expansion of the diameter of the ring.

  As shown in FIGS. 1A to 1F, the connecting portion 15 is formed in a long rectangular plate shape, and the engaging portions 13 and 14 are connected to both ends in the longitudinal direction. The engaging portions 13 and 14 are connected to the front end and the rear end of the connecting portion 15 at portions adjacent to the front ends 13S and 14S with respect to the buckles 13B and 14B. Moreover, although the engaging parts 13 and 14 are arrange | positioned so that it may orthogonally cross in the elongate direction of the connection part 15, the engaging part 13 is arrange | positioned so that the front-end | tip 13S may face the right direction, The tip 14S is arranged so as to face leftward.

  The belt body 11 is connected at its longitudinal center part to the longitudinal center part of the connecting part 15. The band 11 intersects the connecting portion 15 at an angle of 80 ° in plan view in a natural state where no external force is applied to the holder 10. As shown in FIGS. 1A to 1F, the belt body 11, the engaging portion 13, the engaging portion 14, and the connecting portion 15 are connected with the plate thickness direction aligned, and the connecting portion 15 is The belt body 11, the engaging portion 13, and the engaging portion 14 are configured to be thicker than the portions other than the buckles 11B, 13B, and 14B. For this reason, the connecting portion 15 has higher rigidity than the band body 11, the engaging portion 13, and the engaging portion 14.

  Next, the usage method and effect of the holder 10 configured as described above will be described. FIG. 3 shows an example in which the holder 10 is attached to the ferrite clamp 90. As shown in FIG. 3, the ferrite clamp 90 includes a pair of cases 91 and 92 each holding a ferrite core (not shown: an example of a half-split magnetic body) having a shape obtained by dividing a cylinder into two. The ferrite cores held in the cases 91 and 92 have the same shape as the cases 91 and 92 and are slightly smaller. That is, the cases 91 and 92 are configured in a half-cylindrical shape along the outer periphery of the ferrite core, and are connected to each other via a hinge (not shown).

  Further, the electric wire 100 is inserted into the through hole along the axis of the cylindrical body formed by combining the pair of ferrite cores, and the semicircular cutout 91A for allowing the case 100 to pass through the electric wire 100 is also inserted. , 92A are formed. Although only one is shown in FIG. 3, the notches 91 </ b> A and 92 </ b> A are formed on both sides of the cases 91 and 92 in the axial direction. For this reason, the electric wire 100 protruding from the openings at both ends of the through hole of the cylindrical body further protrudes from a circular hole (wire insertion hole) formed by the notches 91A and 92A at both ends of the ferrite clamp 90.

  The cases 91 and 92 in the state shown in FIG. 3 individually hold the ferrite cores so that the pair of ferrite cores are combined as a cylindrical body. The holder 10 is used by winding the belt 11 around the peripheral surfaces of the cases 91 and 92. The band 11 is fastened to the peripheral surfaces of the cases 91 and 92 using a ratchet mechanism including the teeth 11A and the buckle 11B. At this time, the strip 11 is disposed along a plane orthogonal to the axis of the ferrite clamp 90.

  Subsequently, the engaging portions 13 and 14 are similarly formed on the electric wire 100 protruding from the circular hole formed by the notches 91A and 91B at both ends of the ferrite clamp 90 (hereinafter simply referred to as protruding from both ends of the ferrite clamp 90). Tightened. Then, the connection part 15 is arrange | positioned in the direction along the axis | shaft of the ferrite clamp 90 so that a pair of engaging parts 13 and 14 may be connected. In other words, the belt body 11 and the connecting portion 15 are about to be disposed at orthogonal positions. As described above, in a natural state in which no external force is applied to the holder 10, the belt body 11 and the connecting portion 15 intersect at an angle of 80 °. At this time, at this time, FIGS. ) As shown in FIG.

  That is, when the engaging portions 13 and 14 are engaged with the electric wire 100 from the center of the portion where the connecting portion 15 is connected to the belt body 11 (the portion indicated by the arrow X in FIG. 1A), the engaging portion The direction to the position where the center of the electric wire 100 is disposed with respect to 13 and 14 (the position indicated by the arrow Y in FIG. 1A) is a band in a natural state where no external force is applied to the holder 10. 11 intersect with the longitudinal direction at an angle different from 90 °. Thus, due to the positional relationship between the engaging portions 13, 14 defined by the connecting portion 15 and the band body 11, the band body 11 is twisted as described above when mounted on the ferrite clamp 90 and the electric wire 10.

  This twist reduces the inner circumference of the ring formed by the band 11 and improves the strength with which the band 11 clamps the peripheral surface of the ferrite clamp 90. That is, the looseness of the belt body 11 for one ratchet (one tooth of the teeth 11A) can be absorbed. In addition, there is a case where the tightening strength can be further improved. Therefore, when the holder 10 is used, the ferrite clamp 90 can be tightened with good strength.

  Further, the holder 10 can be fixed at a predetermined position of the electric wire 100 together with the ferrite clamp 90 when the engaging portions 13 and 14 tighten the electric wire 100. Therefore, the ferrite core can be fixed at an appropriate position so that the noise current can be more satisfactorily absorbed.

[Second Embodiment]
The holder 20 shown in FIGS. 4A to 4F is different from the holder 10 in that engaging portions 23 and 24 are provided at both ends of the connecting portion 15 instead of the engaging portions 13 and 14. The others are configured similarly to the holder 10. In addition, in each following embodiment, the same structure as the holder 10 is attached | subjected to the location with the same referential mark as FIGS. 1-3 in a corresponding drawing, and detailed description of a structure is abbreviate | omitted. Hereinafter, differences will be described.

  The engaging portions 23 and 24 are raised upward from both ends of the connecting portion 15 in the front-rear direction, and V-shaped cuts 23A and 24A are formed at the centers of the tips. As shown in FIG. 5, the holder 20 configured as described above is configured such that after the electric wires 100 protruding from both ends of the ferrite clamp 90 are respectively inserted into the notches 23 </ b> A and 24 </ b> A, the band 11 is rotated around the ferrite clamp 90. Tightened to the surface.

  In a natural state where no external force is applied to the holder 20, the connecting portion 15 and the belt body 11 intersect at an angle of 80 °. Therefore, before the belt body 11 is tightened, the belt body 11 is connected to the ferrite clamp 90. Arranged along a plane that intersects the axis at an angle of 80 °. However, as the band 11 is tightened, the band 11 is gradually displaced so as to be disposed along a plane perpendicular to the axis of the ferrite clamp 90. For this reason, also in the holder 20, as the band body 11 is tightened more strongly, the band body 11 is twisted, and like the holder 10, the ferrite clamp 90 can be tightened with good strength.

[Third Embodiment]
The holder 30 shown in FIGS. 6 (A) to 6 (F) is held at the point where the connecting portion 15 and the belt 11 are orthogonal to each other and at the positions where the notches 33A and 34A are formed in the engaging portions 33 and 34. Unlike the tool 20, the rest is configured in the same manner as the holder 20. That is, the cut 33A is formed by cutting into a V shape from a position on the right side of the tip of the engaging portion 33, and the cut 34A is formed by cutting into a V shape from a position on the left side of the tip of the engaging portion 34. Has been.

  For this reason, in the holder 30, in a natural state where no external force is applied to the holder 30, the line connecting the centers of the cuts 33 </ b> A and 34 </ b> A intersects the longitudinal direction of the band 11 at an angle of 85 °. Yes. Further, when the engaging portions 33 and 34 are engaged with the electric wire 100 from the center of the portion where the connecting portion 15 is connected to the belt body 11, the center of the electric wire 100 is disposed with respect to the engaging portions 33 and 34. In the natural state where no external force is applied to the holder 30, the direction to reach the position (the center of the cuts 33 </ b> A and 34 </ b> A) intersects with the longitudinal direction of the band 11 at an angle different from 90 °. . Therefore, in the holder 30, although the connection part 15 and the strip | belt body 11 are orthogonal, the effect similar to the holder 20 arises. That is, the ferrite clamp 90 can be tightened with good strength by twisting the band 11 as shown in FIG.

[Fourth Embodiment]

In addition, this invention is not limited to the said embodiment at all, It can implement with a various form in the range which does not deviate from the summary of this invention. For example, the angle is not limited to 80 °, and any angle other than 90 ° has an effect. However, when the angle is 65 ° or more (preferably 75 ° or more), the attaching operation of the holder is easier. Further, when the angle is less than 90 ° (desirably 85 ° or less), the tightening effect due to the twist appears well. Therefore, when the angle is any angle between 65 ° and less than 90 ° (preferably 75 ° to 85 °), the workability of the mounting operation is further improved, and the ferrite clamp 90 is further improved. It can be tightened with strength.

  In each of the above embodiments, the ferrite clamp 90 is tightened and held, but the ferrite core into which the electric wire is inserted may be directly tightened and held.

  Moreover, the form of a connection part and a strip | belt body can be changed variously. However, in each said embodiment, the connection parts 15,45,55 and the strip | belt bodies 11 and 41 are comprised by the elongate plate shape. Moreover, when the connecting portions 15, 45, 55 and the strips 11, 41 are deployed in a planar shape as shown in FIGS. 1, 4, 6, 8, and 12, the connecting portions 15, 45, 55 and the thickness direction of the strips 11 and 41 are aligned. For this reason, in each said embodiment, the force which produces the twist to the strips 11 and 41 when it mounts | wears with the ferrite clamp 90 is along the surface of a plate-shaped member (namely, along the direction where bending rigidity is large). And the twist can be generated more satisfactorily. Therefore, in each of the embodiments, the ferrite clamp 90 can be tightened with a better strength. Further, only one of the engaging portions may be provided.

  Further, the engaging portions 53 and 54 of the holder 50 do not necessarily require mechanical strength like the engaging portions of the other holders 10 to 40. The band 11 can be replaced with a surface fastener such as the band 41. Therefore, you may comprise a holder by punching a hook-and-loop fastener so that it may become the shape similar to the holder 50 (however, the part of the buckle 11B is made into the same thickness as another part).
