DETAILED DESCRIPTION OF THE INVENTION

[0010] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. However, the present invention is not limited to these embodiments. Furthermore, the components in the following embodiments include those that are easily replaceable by those skilled in the art, or those that are substantially the same.

[0011] [Embodiment 1] A first embodiment will be described with reference to Figures 1 to 5. As shown in Figure 1, a wire harness WH includes a wiring material W to be routed to a fixed object 100, and a clamp 1 attached to the wiring material W to fix the wiring material W to the fixed object 100. The wire harness WH in this embodiment is configured to connect the wiring material W used for power supply and signal communication to each device mounted on a vehicle, for example, using a connector or the like (not shown). The wire harness WH may also include a grommet, a protector, etc. (not shown).

[0012] The wiring material W of this embodiment is an insulated electric wire that includes a conductive conductor portion (core wire) and an insulating insulating coating portion, and the conductor portion is coated with the insulating coating portion. The conductor portion here is a stranded wire formed by twisting together multiple wires made of a conductive metal. The insulating coating portion is formed, for example, by extrusion molding an insulating resin material (PP, PVC, cross-linked PE, etc., appropriately selected taking into consideration abrasion resistance, chemical resistance, heat resistance, etc.). The conductor portion of the wiring material W may be a bundle of multiple wires. The wiring material W may be a single wire, or a wiring material bundle of two or more wires. The wiring material W may be exteriorly covered with a tubular body such as a corrugated tube.

[0013] The wiring material W is fixed to the clamp 1 by wrapping adhesive tape TP around the wiring material holding portion 20, which is a plate-shaped wiring material, provided on the clamp 1. The wiring material holding portion 20 is formed in the shape of a long rectangular plate. The wiring material W that holds the wiring material W in this manner is arranged in the wiring material holding portion 20 with the extension direction of the wiring material W aligned with the longitudinal direction of the wiring material holding portion 20. The adhesive tape TP is wrapped around the wiring material holding portion 20 at two locations on both ends of the anchor portion 10 of the clamp 1. Note that the wiring material W may be fixed to the wiring material holding portion 20 using a cable tie or the like instead of adhesive tape TP.

[0014] The fixing object 100 may be, for example, a vehicle body in which a wire harness WH is routed. The fixing object 100 is provided with a recess 101. The recess 101 is, for example, a concave circular hole that does not penetrate the fixing object 100. Therefore, inside the recess 101, a peripheral wall surface 102 having a cylindrical inner peripheral surface shape is provided.

[0015] The wire harness WH is fixed to the object 100 by inserting the anchor portion 10 of the clamp 1 into the recess 101 of the object 100. The clamp 1 fixed to the object 100 can be removed from the recess 101 by strongly pulling it out. In the following explanation, the direction in which the anchor portion 10 is attached to or removed from the recess 101 is referred to as the attachment direction IS. In addition, in the attachment direction IS, the opening side of the recess 101 (the wiring material W side of the wire harness WH) will be described as the upper side, and the bottom side of the recess 101 (the clamp 1 side of the wire harness WH) will be described as the lower side.

[0016] As shown in Figures 2 and 3, the clamp 1 has an anchor portion 10, a wiring material holding portion 20, and a flange 30. In this embodiment, the wiring material holding portion 20 and the flange 30 are integrally formed from a hard resin material. The flange 30 includes a connection portion 31, which will be described later. On the other hand, the anchor portion 10 is formed from a flexible and compressible material such as rubber. The clamp 1 is formed by combining the wiring material holding portion 20 and flange 30, which are integrally formed, with the anchor portion 10. In this way, the anchor portion 10, or at least the elastically deforming portion 12a, is typically formed from a soft resin material (e.g., rubber) having relatively high elasticity compared to the wiring material holding portion 20. In other words, the wiring material holding portion 20, including the flange 30, is typically formed from a hard resin material having relatively high rigidity compared to the anchor portion 10, or at least the elastically deforming portion 12a.

[0017] The anchor part 10 is provided with a substantially cylindrical shaft part 11. The axis CL of the shaft part 11 of the anchor part 10 is arranged along the mounting direction IS when the clamp 1 is attached to or detached from the recessed part 101. In other words, the axis CL is provided along the mounting direction IS to the recessed part 101.

[0018] The lower tip portion of the shaft portion 11 is formed in a substantially bullet-shaped form. A plurality of ribs 12 are provided on the outer peripheral surface of the shaft portion 11. Each rib 12 is formed in the form of a vertical rib extending in the direction of the axis CL (in other words, the mounting direction IS). The plurality of ribs 12 are provided radially around the axis CL. In other words, each rib 12 is formed in the form of a plate with its plate surface facing around the axis CL. The plurality of ribs 12 are provided in a pleated form. The lower portion of each rib 12 is formed in a curved form that follows the bullet-shaped form of the tip portion of the shaft portion 11. This, together with the bullet-shaped form of the shaft portion 11, makes it easier to insert into the recess 101. Furthermore, the upper side of each rib 12 is formed at a substantially right angle.

[0019] Each rib 12 includes an elastically deformable portion 12a that can be pressed against a peripheral wall surface 102 of a recess 101 provided in the object 100 to be fixed. The anchor part 10, which includes the multiple ribs 12 and the shaft part 11, is integrally formed from a flexible and compressible material such as rubber. The elastically deformable portion 12a of each rib 12 is at least a region near an end face 12b of each rib 12 on the radially outer side of the shaft part 11. More specifically, the outer diameter D1 of the multiple ribs 12 is set to be larger than the diameter DA of the recess 101 (see FIG. 4). The elastically deformable portion 12a is a portion that compresses and bends to absorb the difference (D1-DA) between the outer diameter D1 of the multiple ribs 12 and the diameter DA of the recess 101 when the anchor part 10 is inserted into the recess 101, i.e., a portion that elastically deforms.

[0020] The flange 30, which is integrally formed with the wiring material holding portion 20, is formed in a disk shape. A cylindrical connecting portion 31 is provided on the flange 30, protruding concentrically from the underside of the flange 30. The connecting portion 31 is formed with the same diameter as the shaft portion 11 of the anchor portion 10. The upper end face of the shaft portion 11 is connected to the lower end face of the connecting portion 31 of the flange 30. The flange 30, the connecting portion 31, and the shaft portion 11 are concentrically connected at the axis CL. The connecting portion 31 and the shaft portion 11 can be connected by, for example, adhesive bonding, welding, or a locking structure. In this way, the wiring material holding portion 20, which holds the wiring material W, is connected to the anchor portion 10. The flange 30 is provided between the wiring material holding portion 20 and the anchor portion 10. A predetermined interval S1, which is the distance between the underside of the flange 30 and the upper end of the rib 12, is the length of the connecting portion 31 in the direction of the axis CL. The length of the wiring material holding portion 20 in the short direction is formed to be slightly larger than the diameter of the flange 30. The size and shape of the wiring material holding portion 20 are set appropriately in accordance with the wiring material W.

[0021] FIG. 4 shows a cross section of the recess 101 and the wiring material W of the object 100, and a side view of the clamp 1. The adhesive tape TP is indicated by a two-dot chain line. The same applies to FIGS. 8, 12, and 16, which illustrate other embodiments. As shown in FIG. 4, the wire harness WH is fixed to the object 100 by inserting the anchor portion 10 into the recess 101 along the mounting direction IS. At this time, the lower surface of the flange 30 abuts against the peripheral edge 103 of the opening of the recess 101, covering and sealing the opening. In other words, the flange 30 is formed larger than the opening of the recess 101 so that it can abut against the peripheral edge 103. This appropriately prevents the anchor portion 10 from entering the recess 101, even if the depth of the recess 101 is sufficiently longer than the length of the anchor portion 10. The positions of the multiple ribs 12 in the mounting direction IS of the recess 101 can be appropriately set at a predetermined interval S1.

[0022] 5, when anchor portion 10 is inserted into recess 101, end face 12b of each rib 12 is pressed against peripheral wall surface 102 of recess 101, and elastically deforming portion 12a is compressed and elastically deformed as described above. The amount of deformation of elastically deforming portion 12a is set to an extent that clamp 1 cannot be easily removed from recess 101 due to the frictional force between end face 12b and peripheral wall surface 102 generated by the pressing force of end face 12b of each rib 12 against peripheral wall surface 102.

[0023] [Embodiment 2] Next, a second embodiment will be described with reference to Figures 6 to 9. A clamp 201 of the second embodiment has ribs 212 inclined in one direction around the axis CL instead of the vertical rib-like ribs 12 of the clamp 1 of the first embodiment. In the following, members and parts common to the first embodiment will be given the same reference numerals, and their description will be omitted or simplified.

[0024] As shown in FIGS. 6 and 7, the ribs 212 extend in the direction of the axis CL. The ribs 212 are arranged around the axis CL. When viewed from the direction of the axis CL, each rib 212 is inclined in one direction around the axis CL with respect to the radial direction of the stem 11. In this embodiment, as shown in FIG. 7, the ribs 212 are inclined counterclockwise when viewed from below in the direction of the axis CL. In other words, the center CT of each rib 212 in the thickness direction is disposed at a predetermined angle θ1 in the counterclockwise direction with respect to the radial direction DM of the stem 11. The thickness of each rib 212 is gradually reduced from the base end side (the stem 11 side) to the tip end side (the side opposite the base end in the direction in which each rib 212 extends as viewed from the direction of the axis CL). The outer diameter D2 of the ribs 212 is greater than the diameter DA of the recess 101.

[0025] As shown in Figures 8 and 9, when the anchor portion 10 of the clamp 201 is inserted into the recess 101 to fix the clamp 201, most of the outer side surfaces 212b of the ribs 212 are pressed against the peripheral wall surface 102 of the recess 101, causing each rib 212 to elastically deform and compress, further tilting in the tilting direction. In other words, each rib 212 is formed in a folded shape so that it is folded in the tilting direction. The entirety of each rib 212 serves as an elastically deformable portion 212a that can be pressed against the peripheral wall surface 102. By forming each rib 212 so that its thickness gradually decreases outward, the base end of each rib 212 has increased elasticity and is firmly pressed against the peripheral wall surface 102, while the thinner outer side is in close contact with the peripheral wall surface 102, generating high friction.

[0026] [Embodiment 3] Next, a third embodiment will be described with reference to Figures 10 to 14. A clamp 301 of the third embodiment has a rib 312 formed in a disk shape and arranged concentrically with the axis CL, instead of the vertical rib-like rib 12 of the clamp 1 of the first embodiment. In the following, members and parts common to the first embodiment will be given the same reference numerals, and their description will be omitted or simplified.

[0027] As shown in FIG. 10, a plurality of ribs 312 are provided, and each rib 312 is formed in a substantially circular plate shape. The ribs 312 are provided at equal intervals along the axis CL and concentrically about the axis CL. As shown in FIG. 11, which is an encircled view of part P2 in FIG. 10, a peripheral edge portion 312b near the radially outer edge of each rib 312 is formed thinner than a portion radially inward from the peripheral edge portion 312b. In this embodiment, the thin peripheral edge portion 312b serves as an elastically deformable portion 312a. The outer diameter D3 of each rib 312 is larger than the diameter DA of the recess 101.

[0028] As shown in FIG. 12 , when the anchor portion 10 of the clamp 301 is inserted into the recess 101, the peripheral edge 312b elastically deforms and rolls up. During insertion of the anchor portion 10, as shown in FIG. 13 , a portion of the lower surface 312b1 of the peripheral edge 312b of each rib 312 comes into contact with the peripheral wall surface 102, and the anchor portion 10 can be inserted by sliding along this contact surface. After the clamp 301 is attached to the recess 101, when an upward force in the attachment direction IS acts on the clamp 301, as shown in FIG. 14 , the peripheral edge 312b elastically deforms such that the upper surface 312b2 of the peripheral edge 312b comes into contact with the peripheral wall surface 102. As the peripheral edge 312b elastically deforms from FIG. 13 to FIG. 14 , it is compressed radially between the peripheral wall surface 102 and the peripheral wall surface 102, thereby increasing the force with which the peripheral edge 312b presses against the peripheral wall surface 102. Therefore, the frictional force between the peripheral edge portion 312b and the peripheral wall surface 102 is also increased, and the anchor portion 10 does not easily come out of the recess 101.

[0029] Each rib 312 may be entirely made of a soft resin material of uniform thickness. However, by forming each rib 312 so that the elastic force of the peripheral edge portion 312b is lower than that of the inner portion of the peripheral edge portion 312b as in this embodiment, it is possible to make the anchor portion 10 easy to insert into the recess 101 while making it difficult to remove, as described above.

[0030] [Embodiment 4] Next, a fourth embodiment will be described with reference to Figures 15 and 16. A clamp 401 of the fourth embodiment has a rib 412 spirally arranged around an axis CL instead of the vertical rib-like rib 12 of the clamp 1 of the first embodiment. In the following, members and parts common to the first embodiment will be given the same reference numerals, and their description will be omitted or simplified.

[0031] An outer diameter D4 of the rib 412 is larger than a diameter DA of the recess 101. When the anchor portion 10 is inserted into the recess 101, a peripheral edge portion 412b on the radially outer side of the spiral rib 412 elastically deforms, and an end face 412c and a lower face 412d of the rib 412 are pressed against the peripheral wall surface 102. Therefore, the elastically deforming portion 412a of the rib 412 can be the peripheral edge portion 412b.

[0032] When the clamp 401 is inserted into the recess 101, the peripheral edge 412b first receives a reaction force F1 from the object 100 at a contact point FT between the rib 412 and the opening edge of the recess 101, and begins to elastically deform. The contact point FT moves upward along the spiral rib 412, as indicated by the arrow FS, as the anchor part 10 moves downward in the attachment direction IS.

[0033] Furthermore, when the anchor part 10 is inserted into the recess 101, the space surrounded by the pitches of the spiral of the rib 412 and the peripheral wall surface 102 is compressed due to elastic deformation of the peripheral edge part 412b. As the space is compressed, the pressure in the space increases, but the air in the space passes between the pitches of the spiral as shown by arrow FA and is discharged to the outside of the recess 101. Therefore, the resistance encountered when the clamp 401 is inserted into the recess 101 can be reduced.

[0034] When the anchor part 10 is inserted into the recess 101 until the flange 30 abuts against the peripheral edge part 103 and the clamp 401 is completely attached to the object 100, the end face of the peripheral edge part 412b of the rib 412 presses against the peripheral wall surface 102, generating a high frictional force. This fixes the clamp 401 in place and prevents it from easily coming out of the recess 101.

[0035] The clamps 1, 201, 301, 401 described above have a shaft portion 11 provided with ribs 12, 212, 312, 412 including elastically deforming portions 12a, 212a, 312a, 412a that can be pressed against a peripheral wall surface 102 of a recess 101 provided in a fixed object 100, and are equipped with an anchor portion 10 whose axis center CL is provided along an attachment direction IS to the recess 101, and a wiring material holding portion 20 connected to the anchor portion 10 and holding a wiring material W. Also, a wire harness WH is equipped with a wiring material W to be routed to the fixed object 100, and the clamps 1, 201, 301, 401 attached to the wiring material W and fixing the wiring material W to the fixed object 100. This allows the ribs 12, 212, 312, 412 to be pressed against and fixed to the peripheral wall surface 102 of the recess 101, so that the clamps 1, 201, 301, 401 can be properly fixed to the object 100 to which they are to be fixed, and the wiring material W can be routed.

[0036] Conventionally, when attaching a clamp for a wire harness to a pressed body of a vehicle or the like, a method has been adopted in which a through-hole is formed in the body by pressing, and the edge of the opening of the through-hole is clamped and hooked to secure the wire harness. However, in recent years, vehicle bodies have sometimes been manufactured using a molding method called Gigacast, which makes it difficult to form a through-hole in the body and hook the clip's engagement claws into the opening of the hole. Therefore, the clamps 1, 201, 301, and 401 of the present embodiment are designed to properly secure the wire harness WH to the body or the like by pressing the elastically deformable portions 12a, 212a, 312a, and 412a of the ribs 12, 212, 312, and 412 against the peripheral wall surface 102, generating frictional force, even in cases where the opening of the hole is a recessed portion with a bottom that does not allow the clip's engagement claws to hook.

[0037] Furthermore, the clamps 1, 201, 301, and 401 are provided with a flange 30 that is provided between the wiring material holding portion 20 and the anchor portion 10 and can abut against the peripheral portion 103 of the opening of the recess 101. This allows the anchor portion 10 of the clamps 1, 201, 301, and 401 to be pushed into the recess 101 until the flange 30 abuts against the peripheral portion 103 of the recess 101, thereby improving the efficiency of the installation work of the clamps 1, 201, 301, and 401 into the recess 101.

[0038] Furthermore, the ribs 12 are vertical ribs extending in the installation direction IS, and are provided in multiple numbers radially around the axis CL. This allows the clamp 1 to be fixed in the recess 101 while air inside the recess 101 is discharged to the outside of the recess 101 from between adjacent ribs 12 when the anchor part 10 is inserted into the recess 101, thereby reducing resistance when the clamp 1 is installed.

[0039] Furthermore, a plurality of ribs 212 are provided, extending in the mounting direction IS and inclined in one direction around the axis CL. This reduces the amount of elastic deformation that occurs when elastically deforming portions 212a of rib 212 are crushed when anchor part 10 is inserted, thereby reducing the force required when inserting clamp 201 into recess 101, and also increases the frictional force that occurs when side surfaces 212b of rib 212, which have a large area, come into contact with peripheral wall surface 102, thereby increasing the force required to pull out clamp 201, making it more difficult for it to come out.

[0040] Furthermore, the ribs 312 are formed in a disk shape, and a plurality of ribs 312 are provided concentrically about the axis CL. As a result, when the clamp 301 tries to come out of the recess 101, the peripheral edge 312b of the rib 312 comes into surface contact with the entire periphery of the peripheral wall surface 102, making it difficult for the clamp 301 to come out.

[0041] Furthermore, rib 412 is provided spirally around axis CL, thereby reducing the resistance when clamp 401 is inserted into recess 101, and further improving the efficiency of the clamp 401 fixing operation.

[0042] The clamp and the wire harness according to the embodiment of the present invention described above are not limited to the above embodiment, and various modifications are possible within the scope of the claims.

[0043] In the above description, the wiring material holding portion 20 is formed in a plate shape and the wiring material W is fixed with adhesive tape TP, but this is not limited to this and various methods can be adopted, such as a method of fixing the wiring material W with a band or a method of fixing the wiring material W with a clip.

[0044] Furthermore, although the clamps 1, 201, 301, and 401 are provided with the flange 30, the flange 30 can be omitted. Instead of the flange 30, a plate-shaped wiring material holding portion 20 can be abutted against the peripheral edge portion 103 to restrict the anchor portion 10 from entering the recess 101. The connecting portion 31 can also be omitted as appropriate. For example, the anchor portion 10 can be configured to be directly connected to the wiring material holding portion 20.

[0045] In addition, in this embodiment, the clamps 1, 201, 301, 401 are formed by forming the wiring material holding portion 20, flange 30, and connection portion 31 from a hard resin material, and connecting the shaft portion 11 of the anchor portion 10 made of rubber or the like to the connection portion 31.However, for example, the wiring material holding portion 20, flange 30, connection portion 31, and shaft portion 11 of the anchor portion 10 can be formed from a hard resin material, and the ribs 12, 212, 312, 412 including the elastic deformation portions 12a, 212a, 312a, 412a can also be formed from a flexible and compressible material. Furthermore, a part of the ribs 12, 212, 312, 412 (for example, the base end part connected to the shaft 11) together with the wiring material holding portion 20, the flange 30, the connecting portion 31, and the shaft 11 may be formed of a hard resin material, and only a part of the ribs 12, 212, 312, 412 including the elastically deforming portions 12a, 212a, 312a, 412a may be formed of a flexible and compressible material. That is, it is sufficient that at least the elastically deforming portions 12a, 212a, 312a, 412a of the ribs 12, 212, 312, 412 of the clamps 1, 201, 301, 401 are formed of a flexible and compressible material. The clamps 1, 201, 301, 401 can be manufactured, for example, by two-color molding, in which the hard resin material portion (wiring material holding portion 20, flange 30, etc.) and the soft resin material portion (at least the elastic deformation portion 12a, 212a, 312a, 412a) are integrally molded.

[0046] The clamp and the wire harness according to this embodiment may be configured by appropriately combining the components of the above-described embodiments and modified examples. [Explanation of symbols]
