[0009] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited to the following embodiments. That is, the components in the following embodiments include those that can be easily imagined by a person skilled in the art or those that are substantially the same, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention.

[0010] In the following description, of the X, Y, and Z directions shown in the drawings, the X direction will be referred to as the "extension direction X," the Y direction will be referred to as the "width direction Y," and the Z direction will be referred to as the "height direction Z." The extension direction X, width direction Y, and height direction Z are all perpendicular to one another. The extension direction X corresponds to the extension direction of the band clamp 1, the first member 2, and the second member 3. The width direction Y corresponds to the width direction of the band clamp 1, the first member 2, and the second member 3. The height direction Z corresponds to the height direction of the band clamp 1, the first member 2, and the second member 3. Unless otherwise specified, the directions used in the following description will be described as directions when the various parts of the band clamp 1 are assembled.

[0011] [Embodiment] 1 to 5 is fixed to, for example, the body of a vehicle and has the function of regulating the routing path of a wire harness WH. The wire harness WH is, for example, a collective component made by bundling together multiple wiring materials W used for power supply and signal communication to connect various devices mounted on the vehicle, and the multiple wiring materials W are connected to each device with connectors or the like (not shown).

[0012] The wiring material W is composed of, for example, a conductive linear core wire and an insulating covering portion that covers the outside of the core wire. The wiring material W is, for example, an insulated electric wire in which the core wire is covered with a covering portion. The core wire is composed of a plurality of wires made of a conductive metal, such as copper, copper alloy, aluminum, or aluminum alloy, bundled together. The core wire may also be a twisted core wire in which a plurality of wires are twisted together. The covering portion is an electric wire covering that covers the outer side of the core wire. The covering 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.).

[0013] The band clamp 1 is made of an insulating resin material or the like. The band clamp 1 of this embodiment is composed of two members: a first member 2 and a second member 3 formed to be able to fit into the first member 2.

[0014] First, we will explain the first member 2. The first member 2 is a member that bundles the wire harness WH. The first member 2 has a band-shaped portion 10 and a main body portion 11 that is formed integrally with the band-shaped portion 10.

[0015] As shown in Fig. 2, the band-shaped portion 10 is a portion that is wound around the outer periphery of the wire harness WH. The band-shaped portion 10 extends in a band shape from the main body portion 11 and is capable of binding the wire harness WH by being locked to the main body portion 11 in a state where it is wound around the wire harness WH. The base end of the band-shaped portion 10 is connected to the main body portion 11, and extends in a direction away from the main body portion 11 in an unbound state where the first member 2 does not bind the wire harness WH.

[0016] The strip portion 10 has a substantially rectangular cross section perpendicular to the thickness direction, and is formed to have the same thickness along the extension direction X. A portion of the tip end of the strip portion 10 is formed so that its cross section is smaller, tapering toward the tip end.

[0017] The band-shaped portion 10 is flexible in the thickness direction. The band-shaped portion 10 is wound around the wire harness WH in the circumferential direction, and is inserted into an insertion hole 12 provided in a main body 11 (described later), with an excess portion extending from the insertion hole 12 in a direction (height direction Z in FIG. 2) intersecting the extending direction of the wire harness WH (width direction Y in FIG. 2).

[0018] The band-shaped portion 10 also has a plurality of sawtooth-shaped teeth 14 on one flat surface. The teeth 14 are provided on the inside of the band-shaped portion 10. The teeth 14 have the same shape and extend in a direction perpendicular to the flat surface of the band-shaped portion 10. The teeth 14 are arranged in a straight line at intervals in the extension direction X of the band-shaped portion 10. When the band-shaped portion 10 is inserted into the insertion hole 12 of the main body portion 11, the locking protrusions 12a lock into the teeth 14 of the band-shaped portion 10. The locking protrusions 12a lock into the teeth 14, restricting the movement of the band-shaped portion 10 in the direction of removal from the insertion hole 12.

[0019] The main body 11 is a base of the first member 2. The main body 11 is formed in a hollow box shape and has an internal space 11a inside. The main body 11 includes an insertion hole 12 that does not communicate with the internal space 11a, and five fitting holes 15 that are provided separately from the insertion hole 12.

[0020] The insertion hole 12 is a through-hole formed to allow the band-shaped portion 10 to pass therethrough and to lock the band-shaped portion 10 along the extension direction X of the band-shaped portion 10. In this embodiment, the insertion hole 12 extends in the height direction Z of the main body 11 and has a locking protrusion 12a on its inner surface. When the band-shaped portion 10 is inserted into the insertion hole 12, the locking protrusion 12a locks the tooth 14 of the band-shaped portion 10.

[0021] The fitting hole 15 is a through-hole provided separately from the insertion hole 12, and is a hole that communicates between the internal space 11a of the main body 11 and the external space. The fitting hole 15 is formed in a rectangular shape, and is formed so that a part of the second member 3 can be fitted therein. As shown in FIGS. 1 to 5, one fitting hole 15 is formed in each of the five fitting surfaces 13A, 13B, 13C, 13D, and 13E.

[0022] The mating surfaces 13A to 13E are flat surfaces that face and abut against a portion of the second member 3, and are provided on the main body 11 facing in different directions. The mating surface 13A is formed facing the opposite side of the strip portion 10, which is on one side in the extension direction X. The mating surfaces 13B and 13E are formed on one side and the other in the height direction Z. The mating surfaces 13C and 13D are formed on one side and the other in the width direction Y.

[0023] Next, we will explain the second member 3. The second member 3 is formed separately from the first member 2, and is a member that is fixed to a fixed object 4 such as a vehicle body. The second member 3 has a fitting portion 20 and a fixing portion 21 that is formed integrally with the fitting portion 20.

[0024] 1, the fitting portion 20 is a portion that fits into the fitting hole 15 of the first member 2. The fitting portion 20 is formed in an anchor shape, and includes a support portion 22 and a pair of arm pieces 23.

[0025] The support portion 22 supports the pair of arm pieces 23. The support portion 22 is formed in a columnar shape and extends outward from the fixed portion 21 toward the fitting hole 15. The pair of arm pieces 23 are connected to the support portion 22.

[0026] The pair of arm pieces 23 are engaged with the main body 11 of the first member 2 when the support portion 22 is inserted into the fitting hole 15. Each of the pair of arm pieces 23 is formed to be elastically deformable. For example, one end of each of the pair of arm pieces 23 is fixed in a cantilevered manner to the tip end of the extension direction of the support portion 22, and the other end is configured as a free end, and is formed to expand from one end side to the other end side in a width direction perpendicular to the extension direction. When the pair of arm pieces 23 are inserted into the fitting hole 15, they are compressed in the width direction to match the size of the fitting hole 15, and after compression, they return to their original shape when they are removed from the fitting hole 15. At this time, the pair of arm pieces 23 are engaged with the first member 2 with the wall portion forming the main body 11 sandwiched between each arm piece 23 and the fixing portion 21.

[0027] 1, the fixing portion 21 is formed integrally with the fitting portion 20 and is configured to be able to be fixed to the fixing target 4. The fixing portion 21 is formed in an anchor shape and includes a main body portion 24 and a pair of arm pieces 25.

[0028] The main body 24 supports the pair of arm pieces 25. The main body 24 is formed in a substantially rectangular parallelepiped shape. The pair of arm pieces 25 are connected to the main body 24.

[0029] As shown in FIGS. 1 and 5 , the pair of arm pieces 25 are engaged with the object 4 with their main body portions 24 inserted into mating holes 4a provided in the object 4. Each of the pair of arm pieces 25 is formed to be elastically deformable. For example, one end of each of the pair of arm pieces 25 is fixed in a cantilevered manner to the distal end of the extension direction of the main body portion 24, and the other end is configured as a free end, and is formed to expand from one end side to the other end side in a width direction perpendicular to the extension direction. When inserted into the mating holes 4a of the object 4, the pair of arm pieces 25 are compressed in the width direction to match the size of the mating holes 4a. After compression, the pair of arm pieces 25 return to their original shape by removing from the mating holes 4a. At this time, the pair of arm pieces 25 are engaged with the object 4 with a wall portion forming the object 4 sandwiched between each arm piece 25 and the main body portion 24.

[0030] The second member 3 of this embodiment can be fitted into the fitting holes 15 provided on each of the five fitting surfaces 13A to 13E. In conventional clamps, the first member 2 and the second member 3 are integrally formed, so the mounting direction of the wire harness WH relative to the object 4 is fixed. Therefore, clamps of various shapes are prepared to accommodate the mounting direction of the wire harness WH and the state of the object 4, naturally resulting in a large number of clamp types. The band clamp 1 of this embodiment is configured such that the first member 2 that fastens the wire harness WH and the second member 3 that is fixed to the object 4 are separate members, and the second member 3 is configured so that it can be fitted into the first member 2 from different directions. This allows the band clamp 1 to be mounted in five different directions, making the band clamp 1 more versatile. Furthermore, the above configuration of the band clamp 1 makes it possible to reduce the number of types of band clamps.

[0031] Furthermore, when the fixing portion 21 of the second member 3 is inserted into the fitting hole 4a of the object 4, the pair of arm pieces 25 are compressed in the width direction to fit the size of the fitting hole 4a, and then return to their original shape by coming out of the fitting hole 4a. As a result, the second member 3 is fixed to the object 4, with the wall portions that form the object 4 sandwiched between each arm piece 25 and the main body portion 24.

[0032] 6 and 7, the second member 3 can also be fixed by fitting the anchor-shaped fitting portion 20 into a fitting hole 15A provided in a member other than the first member 2. In other words, when it is desired to fix the second member 3, by providing a fitting hole 15A similar to the fitting hole 15 in the object to be fixed, it is possible to fix the second member to an object to be fixed other than the first member 2. In the example of FIGS. 6 and 7, by providing a fitting hole 15A in an exterior member such as a corrugated tube or a protector attached to the wire harness WH and assembling the second member 3 into the fitting hole 15A, it becomes possible to easily fix the wire harness WH to an object to be fixed 4 such as a vehicle body via the second member 3.

[0033] Furthermore, by dividing the band clamp 1 into two parts, the first member 2 and the second member 3, it becomes possible to use the first member 2 as a common part and freely change the shape of the second member 3.

[0034] As described above, the band clamp 1 of this embodiment comprises a first member 2 having a main body 11 including a strip-shaped portion 10 wound around the outer periphery of the wire harness WH, an insertion hole 12 formed integrally with the strip-shaped portion 10, through which the strip-shaped portion 10 is inserted and which can engage the strip-shaped portion 10 along the extension direction of the strip-shaped portion 10, and an engagement hole 15 provided separately from the insertion hole 12, and a second member 3 having an engagement portion 20 formed separately from the first member 2 and which engages with the engagement hole 15, and a fixing portion 21 formed integrally with the engagement portion 20 and which can be fixed to the object to be fixed 4.

[0035] By dividing the band clamp 1 into two parts, the first member 2 and the second member 3, the shape of each member can be changed, and by standardizing the first member 2 and changing only the second member 3, it becomes easy to match the attachment direction of the wire harness WH to the fixed object 4 and the state of the fixed object 4. As a result, there is no longer a need to prepare band clamps of various shapes, and the band clamp 1 can be made more versatile.

[0036] Furthermore, in the band clamp 1 according to this embodiment, the main body 11 includes a plurality of fitting holes 15 that are provided facing in different directions. This allows the band clamp 1 to fit the second member 3 to the first member 2 from different directions, making it possible to adjust the fixing position of the wire harness WH depending on, for example, the shape of the object 4 to be fixed and the surrounding environment.

[0037] In the above embodiment, the fitting hole 15 is formed with a rectangular opening, but is not limited to this and may be circular or elliptical.

[0038] Furthermore, the shape of the arm piece 25 is not limited to the illustrated example, and can be changed to suit the shape of the object 4 to be fixed and the attachment direction to the object 4 to be fixed.

[0039] Furthermore, the fixing part 21 is not limited to the structure described above and shown in the drawings, and may have any structure that can be fixed to the object 4. For example, the fixing part 21 may have a structure in which it is temporarily fixed to the object 4 and then fixed to the object 4 by wrapping a tape member or the like around it.
