Description

[Technical field]

[0001] The present invention relates to a clamp for a wire harness and a mounting structure thereof. [Background technology]

[0002] In a vehicle such as an automobile, a wire harness is arranged for power supply and signal communication. When the wire harness is arranged in the vehicle, a plurality of clamps are generally used for fixing the wire harness to the vehicle. It is important to accurately measure the length between the clamps for the wire harness to be arranged. For example, if the wire harness is measured shorter than the length between the clamps, it cannot be arranged. Conversely, if the wire harness is measured longer than the dimension between the clamps, the wire harness will be excessively long, and space will be wasted accordingly. For this reason, a mark such as a marker is generally attached to the measurement reference position of the clamp for the wire harness, and the dimension of the wire harness between the clamps is generally set to an appropriate length based on the mark (see Patent Document 1). In addition, such a measurement reference position is generally set to the center of the anchor part of the clamp.

[0003] However, when measuring the wire harness, the center of the anchor part is hidden by the wire harness and cannot be seen or is difficult to see. Also, the measurement reference position differs depending on the clamp and is not uniform. Therefore, the measurement location is usually checked in advance, the measurement reference position is measured by eye, and the measurement is performed from the approximate position. Therefore, it is considered that the conventional wire harness clamp has a structure that is prone to human error or error due to the way of looking. [Prior art documents] [Patent documents]

[0010] Hereinafter, the clamp for a wire harness according to the present embodiment will be described in detail with reference to the drawings. Note that the dimensional ratios in the drawings are exaggerated for the convenience of explanation and may differ from the actual ratios.

[0011] <Wire harness clamp> The wire harness clamp of the present embodiment includes a clamp body that holds the wire harness with a tape or band wrapped around it. The clamp body is provided with at least one protrusion that protrudes at a reference position when measuring the dimensions of the wire harness. Hereinafter, the wire harness clamp of the present embodiment will be described with reference to the drawings.

[0012] Fig. 1 to Fig. 3 show an example of a clamp for a wire harness according to the present embodiment. Fig. 1 shows a state before the clamp for a wire harness holds the wire harness. Fig. 2 and Fig. 3 show a state in which the clamp for a wire harness 10 shown in Fig. 1 holds a wire harness 20, with Fig. 2 being a perspective view and Fig. 3 being a top view.

[0013] The wire harness clamp 10 shown in Fig. 1 includes a plate-shaped clamp body 12 and an anchor portion 18. The clamp body 12 includes a protrusion 14 and a protrusion 16 protruding from approximately the center of the side surface. More specifically, the protrusions 14 and 16 protrude at a reference position X when measuring the dimensions of the wire harness. Note that, although the reference position X is located at the center of the clamp body 12 in Fig. 1, it does not necessarily have to be located at the center, and can be set arbitrarily as long as it is a position that serves as a reference for measuring the dimensions of the wire harness. The anchor portion 18 is erected so as to face downward from the clamp body 12, and is inserted into a hole in an attachment target (not shown), thereby fixing the wire harness clamp 10 to the attachment target. Examples of attachment targets include a panel inside an automobile, a mounting bracket, a support, etc. The anchor portion 18 is provided at a reference position X when measuring dimensions. Note that the anchor portion is not necessarily required in the wire harness clamp of this embodiment, and if there is no anchor portion, the clamp is fixed to the attachment target by another fixing means.

[0014] 2 and 3, the wire harness 20 is placed on the upper surface of the clamp body 12 and held in a wrapped state by tapes 22 and 24. Although an example in which the wire harness 20 is held by tapes 22 and 24 is shown in Fig. 2 and 3, the wire harness 20 may be held by a band instead of the tape. Note that in this embodiment, the tape and band are not particularly limited, and any tape or band that is generally used for fixing a wire harness may be used.

[0015] In this embodiment, as shown in Figs. 2 and 3, when the dimension of the wire harness 20 between the clamps is measured in a state where the wire harness 20 is held by the clamp 10 for the wire harness, the convex portion 14 and / or the convex portion 16 are used as a mark. That is, the convex portion 14 and the convex portion 16 are provided at the reference position X when measuring the dimension of the wire harness 20, and therefore serve as the reference position when measuring the dimension of the wire harness 20. Then, by measuring the dimension to the other clamps using the convex portion 14 and / or the convex portion 16 as the reference position, accurate measurement from the reference position X is possible. Therefore, it is possible to prevent the wire harness 20 from becoming shorter or longer between the clamps. In addition, when the reference position X when measuring is marked on the clamp body 12, even if the marking is hidden by the wire harness 20, the convex portion 14 and the convex portion 16 are provided so as not to interfere with the wire harness 20, so there is no problem with the measurement. In addition, Figures 1 to 3 show a configuration in which two protrusions, 14 and 16, are provided on both sides of the side surface of the clamp body 12, but there may be only one protrusion as long as the reference position for taking measurements can be recognized.

[0016] On the other hand, as shown in FIG. 3, the protrusions 14 and 16 have engagement parts 14A and 16A with which the tip of a tape measure can engage, respectively, at the same position as the reference position when measuring the dimension of the wire harness in the longitudinal direction of the wire harness 20. The engagement parts 14A and 16A are formed in a plane normal to the longitudinal direction of the wire harness. That is, the engagement parts 14A and 16A are formed of a surface extending perpendicularly to the side surface of the clamp body 12. Then, as shown in FIG. 4A and FIG. 4B, by engaging the engagement claw 28 at the tip of the tape measure 26 with the engagement part 16A of the protrusion 16, the engagement claw 28 is at the same position as the reference position, so that the dimension can be easily and accurately measured. Note that the engagement parts 14A and 16A are preferably planar when the engagement claw 28 at the tip of the tape measure 26 is engaged, but may not be planar as long as the tip of the tape measure can be engaged. As shown in FIG. 3, both the protrusions 14 and 16 have engaging portions 14A and 16A. When engaging the engaging claw 28 of the tape measure 26, the protrusions 14 and 16, which are shaped like right-angled triangles in a plan view, face in the opposite directions. The opposite sides of the engaging portions 14A and 16A of the protrusions 14 and 16 are inclined from the plane of the engaging portions, and the engaging claw 28 of the tape measure 26 does not engage with them. The engaging claw of the tape measure does not engage with the opposite sides of the engaging portions 14A and 16A, that is, it does not engage with positions deviating from the reference position. In other words, the tip of the tape measure only engages with the engaging portions of the protrusions, and therefore the tip of the tape measure can be engaged only at the reference position, preventing measurement errors.

[0017] In this embodiment, the measuring tape is not particularly limited as long as it can measure the dimensions of the wire harness and has a tip that can engage with the engaging portion of the protrusion. For example, a steel tape measure, a convex, etc. can be used. The tip of the measuring tape may be 0 mm (reference point), or 0 mm (reference point) may be set at a position a certain distance away from the tip.

[0018] As described above, the convex portion 14 and the convex portion 16 are shown as right-angled triangles in plan view from above, but they may be shaped as shown in Figs. 5A, 5B, and 5C. The convex portion 15A shown in Fig. 5A is shaped with a hole 17, the convex portion 15B shown in Fig. 5B is shaped as a polygon, and the convex portion 15C shown in Fig. 5C is shaped as a curve. In either case, the difference in the convex portion allows the clamp to be distinguished from other wire harness clamps. Existing clamps have a number of different shapes, and there is a concern that similar shapes may lead to the wrong clamp being used during assembly during production. However, by making the shape distinguishable from other convex portions as in Fig. 5A, etc., assembly errors can be suppressed.

[0019] <Mounting structure of clamp for wire harness> The mounting structure of the wire harness clamp of this embodiment is a mounting structure in which the above-described wire harness clamp of this embodiment is mounted to a mounting recess to be mounted. The shape of the mounting recess is set so that the wire harness clamp and the mounting recess are fitted together in a convex-concave relationship.

[0020] 6 is a perspective view for explaining the mounting structure of the wire harness clamp of this embodiment. The wire harness clamp 10 fits into a mounting recess 31 of a workpiece 30 to be mounted. That is, a concave-convex relationship is set so that the clamp body 12 of the wire harness clamp 10 fits into the mounting recess 31, the convex portion 14 of the clamp body 12 fits into the recess 32, and the convex portion 16 fits into the recess 34. The anchor portion is fixed by fitting into the through hole 36. In this way, by setting the wire harness clamp 10 and the mounting recess 31 to fit into each other in a concave-convex relationship, it is possible to prevent another wire harness clamp from being attached by mistake.

[0021] Although the present embodiment has been described above, the present embodiment is not limited to this, and various modifications are possible within the scope of the gist of the present embodiment. [Explanation of symbols]
