[0003] [Patent Document 1] Japanese Patent Application Publication No. 11-275743 Summary of the Invention [Problem to be solved by the invention]

[0004] Such clamps and wire harnesses have room for improvement in that they are difficult to assemble automatically. For example, if the clamp is to be attached to the wiring material by wrapping tape around it, the tape must be wrapped around the outer periphery of the wiring material in the circumferential direction, which makes the operation of winding the tape by a manufacturing robot or the like complicated. In addition, when considering the mounting strength of the clamp to the wiring material, the tape must be wrapped multiple times, which requires more complicated operations.

[0009] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited to this embodiment. In addition, the components in the following embodiments include those that are replaceable and easy for a person skilled in the art, or those that are substantially the same.

[0010] [Embodiment] This embodiment relates to a clamp and a wire harness. In the following description, among the first, second, and third directions that intersect with each other, the first direction is referred to as the "extension direction X", the second direction is referred to as the "insertion direction Y", and the third direction is referred to as the "height direction Z". Here, the extension direction X, the insertion direction Y, and the height direction Z are mutually perpendicular. The extension direction X corresponds to the extension direction of the wiring material. The insertion direction Y corresponds to the insertion direction of the wiring material into the clamp. The insertion direction Y and the height direction Z intersect with the extension direction X. In addition, each direction used in the following description represents a direction in a state in which each part is assembled with each other, unless otherwise specified. Note that the orthogonal here includes substantially orthogonal.

[0011] As shown in Figs. 1 to 3, the wire harness WH is a part or assembly that electrically connects devices and the like, and is mounted on, for example, a vehicle for use. The wire harness WH includes a clamp 1 and a wiring material 2. The wiring material 2 is a linear material that is wired to a vehicle body 10 that is a fixed object, and is configured to include, for example, an electric wire that transmits a signal or power. The wiring material 2 may be a bundle of multiple electric wires, or may be a single electric wire. The wiring material 2 may also be a bundle of multiple electric wires that is sheathed in a tubular body. The wiring material 2 extends in the extension direction X, and is fixed to, for example, the vehicle body 10. Note that, in Fig. 1, a panel of the vehicle body 10 is shown as the fixed object, but the fixed object may be a vehicle part or a vehicle component other than the vehicle body 10.

[0012] The clamp 1 is a part or member for fixing the wiring material 2 to the vehicle body 10, and is attached to the wiring material 2 when in use. The clamp 1 includes an anchor portion 3, a main body portion 4, and a clip portion 5. The clamp 1 has the anchor portion 3, the main body portion 4, and the clip portion 5 integrally formed, for example, by resin molding.

[0013] The anchor portion 3 is a portion for attaching the clamp 1 to the vehicle body 10. The anchor portion 3 is inserted into an installation hole 11 formed in the vehicle body 10 and engaged with the vehicle body 10. For example, the anchor portion 3 has an engagement portion 31 that is inserted into and engaged with the installation hole 11. Specifically, the engagement portion 31 is a pair of flexible engagement pieces provided in a tapered shape, and when inserted into the installation hole 11, the engagement portion 31 is engaged with the edge of the installation hole 11 to fix the clamp 1 to the vehicle body 10. In Figs. 1 and 3, the anchor portion 3 is illustrated in a state in which a packing 32 that seals the installation hole 11 is attached. Note that the anchor portion 3 may have a structure other than that described above as long as it can be attached to the vehicle body 10.

[0014] The main body 4 is joined to the anchor portion 3 and has a support surface 41 that contacts the wiring material 2. For example, the main body 4 is plate-shaped, has the support surface 41 formed on the front side, and has the anchor portion 3 joined to the back side. The support surface 41 is a surface that contacts and supports the wiring material 2 when the wiring material 2 is sandwiched and held between the main body 4 and the clip portion 5. A protrusion 411 protrudes from the support surface 41. The protrusion 411 protrudes toward the height direction Z, extends in a direction intersecting the extension direction X of the wiring material 2, and is formed at intervals along the extension direction X. The formation of the protrusion 411 on the support surface 41 increases the pull-out resistance of the wiring material 2 in the extension direction X. As a result, the wiring material 2 is less likely to come out of the clamp 1 in the extension direction X.

[0015] A protrusion 42 is formed on the main body 4. The protrusion 42 is a portion that suppresses the slipping out of the wiring material 2 that is held by being sandwiched between the main body 4 and the clip portion 5. The protrusion 42 is provided on the end 4A on the insertion side of the main body 4 and protrudes in the height direction Z. The end 4A on the insertion side of the main body 4 is the end on the side where the wiring material 2 is inserted. The protrusion 42 suppresses the slipping out of the wiring material 2 in the insertion direction Y. As shown in FIG. 3, the protrusion 42 rotates around the base end portion when the wiring material 2 is inserted, and can be tilted up and down. That is, the protrusion 42 is elastically deformed so as to fall down when pressed by the wiring material 2 from the upright state, allowing the wiring material 2 to be inserted into the main body 4. The protrusion 42 protrudes in a tilted state toward the holding position of the wiring material 2 of the main body 4 except when the wiring material 2 is inserted. In addition, an extension portion 421 extending horizontally is formed at the tip of the protrusion 42. The extension portion 421 prevents the wiring material 2 from going over the protrusion 42 and coming off the main body portion 4.

[0016] As shown in FIG. 3, the clip portion 5 is a portion that inserts the wiring material 2 between the main body portion 4 and the clip portion 5, and holds it by clamping it. The clip portion 5 is joined to the end portion 4B of the main body portion 4, and is provided so as to be rotatable about the end portion 5B with respect to the main body portion 4. The end portion 4B is the end portion opposite to the end portion 4A of the insertion side of the main body portion 4. The end portion 5B is the end portion opposite to the end portion 5A of the insertion side of the wiring material 2 in the clip portion 5. As shown in FIG. 2, for example, the clip portion 5 is joined to the end portion B of the main body portion 4 and is formed as a frame that surrounds the outer periphery of the main body portion 4. The clip portion 5 is elastically deformed by inserting the wiring material 2 between the main body portion 4 and the clip portion 5, and rotates at the end portion 5B around an axis along the extension direction X. The clip portion 5 allows the wiring material 2 to be inserted into the gap of the main body portion 4 by rotating.

[0017] The clip portion 5 is formed with an inclined portion 51. The inclined portion 51 is a portion for facilitating the insertion of the wiring material 2, and is formed at the end portion 5A of the clip portion 5 on the insertion side of the wiring material 2, and is inclined so as to move away from the main body portion 4 toward the tip. Therefore, the insertion opening for the wiring material 2 in the main body portion 4 and the clip portion 5 is wide open, making it easy to insert the wiring material 2.

[0018] A recess 52 is formed in the clip portion 5. The recess 52 is a portion for holding the wiring material 2, and is recessed away from the main body portion 4 at a position where the wiring material 2 is sandwiched. Therefore, the wiring material 2 is sandwiched and held between the main body portion 4 and the clip portion 5 at the position of the recess 52. Since the clip portion 5 is formed to surround the main body portion 4, two recesses 52 are formed to sandwich the main body portion 4. The recess 52 is formed, for example, in an inverted V shape with respect to the wiring material 2. That is, the recess 52 is formed by recessing the surface facing the main body portion 4 in an inverted V shape. Therefore, the recess 52 can suppress the movement of the sandwiched wiring material 2 in a direction intersecting the extension direction X (insertion direction Y). The V shape here includes an almost V shape.

[0019] Next, the assembly of the wire harness WH according to this embodiment will be described.

[0020] The assembly of the wire harness WH is performed by attaching a clamp 1 to a wiring material 2. The assembly of the wire harness WH is performed, for example, by automatic control of a manufacturing device such as a robot arm. Note that the assembly of the wire harness WH may also be performed, for example, by manual labor by an operator for part or all of the assembly process.

[0021] As shown in Fig. 4, the clamp 1 is disposed facing the wiring material 2. For example, the wiring material 2 is fixed so as not to move using a jig or the like, and the clamp 1 is disposed spaced apart in the radial direction of the wiring material 2. The clamp 1 is disposed with the inclined portion 51 of the clip portion 5 facing the wiring material 2.

[0022] Then, the clamp 1 is moved toward the wiring material 2. Then, as shown in Fig. 5, the clamp 1 inserts the wiring material 2 between the inclined portion 51 of the clip portion 5 and the main body portion 4. In this state, the clip portion 5 is not rotating.

[0023] Then, the clamp 1 is pressed further against the wiring material 2 so that the wiring material 2 is inserted up to the recess 52 of the clip portion 5. Then, as shown in Fig. 6, the clip portion 5 flexes and elastically deforms, rotating around the end portion 5B. At this time, the protrusion 42 is pressed by the wiring material 2 and falls down, allowing the wiring material 2 to enter. The wiring material 2 is inserted deep into the main body portion 4 against the restoring force of the elastic deformation of the clip portion 5.

[0024] Then, as shown in FIG. 3, when the wiring material 2 reaches the holding position of the recess 52 of the clip portion 5, the clip portion 5 returns to the position before deformation. The wiring material 2 enters the inside of the recess 52 and is sandwiched and held between the clip portion 5 and the main body portion 4. This completes the assembly of the clamp 1 to the wiring material 2, and the wire harness WH is manufactured. Note that the wire harness WH may be equipped with a part such as a protector as necessary. The assembly of the wire harness WH and the clamp 1 is performed by pressing the clamp 1 against the wiring material 2 to sandwich the wiring material 2 between the clip portion 5 and the main body portion 4. In other words, the clamp 1 can be assembled to the wiring material 2 by performing a process of moving the clamp 1 linearly relative to the wiring material 2. Therefore, the wire harness WH and the clamp 1 are easy to automate the assembly.

[0025] In this assembled state, the recess 52 of the clip portion 5 of the clamp 1 is formed in an inverted V shape, so that the movement of the clamp 1 in the insertion direction Y relative to the wiring material 2 is appropriately suppressed. In addition, the main body portion 4 of the clamp 1, which contacts the wiring material 2, is formed with a protrusion 411, so that the movement of the clamp 1 in the extension direction X relative to the wiring material 2 is suppressed.

[0026] As described above, the clamp 1 and wire harness WH according to this embodiment are held by inserting and sandwiching the wiring material 2 between the main body 4 and the clip portion 5. Therefore, the clamp 1 can be attached to the wiring material 2 by inserting the wiring material 2 between the main body 4 and the clip portion 5 of the clamp 1. Therefore, the clamp 1 and the wire harness WH can be easily assembled and automated.

[0027] In addition, in the clamp 1 and wire harness WH of this embodiment, the clip portion 5 of the clamp 1 has an inclined portion 51, making it easy to insert the wiring material 2 between the main body portion 4 and the clip portion 5, and making it easy to assemble the clamp 1 to the wiring material 2.

[0028] Furthermore, in the clamp 1 and the wire harness WH according to this embodiment, the recess 52 is formed in the clip portion 5 of the clamp 1, so that the clamp 1 can hold the wiring material 2 so as not to move.

[0029] Furthermore, in the clamp 1 and the wire harness WH according to this embodiment, the recess 52 is formed in an inverted V shape, so that it is possible to suppress movement of the sandwiched wiring material 2 in a direction intersecting the extension direction X. In addition, in the clamp 1 and the wire harness WH according to this embodiment, the protrusion 411 is formed in a direction intersecting the extension direction X of the wiring material 2, so that it is possible to suppress movement of the sandwiched wiring material 2 in the extension direction X.

[0030] The clamp and wire harness according to the present invention are not limited to the above-described embodiment, and various modifications are possible within the scope of the claims. The clamp 1 and wire harness WH according to this embodiment may be configured by appropriately combining the components of the above-described embodiment and modified examples.

[0031] For example, in the above embodiment, the clamp 1 and the wire harness WH are mounted on a vehicle, but the clamp and the wire harness according to the present invention may be used without being mounted on a vehicle. [Explanation of symbols]
