Description

[Technical field]

[0001] The present invention relates to a wiring bracket used for routing linear members such as wires and piping to vehicle components mounted on a vehicle. [Background technology]

[0002] Wiring such as harnesses is arranged in vehicle components such as the engine and transmission of a vehicle. This wiring is protected by a protective member such as a corrugated tube, and may be arranged along the shape of the vehicle component. Patent Document 1 discloses a protective structure for a harness arranged in such an engine. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2020-176541 A Summary of the Invention [Problem to be solved by the invention]

[0004] As disclosed in Patent Document 1, wiring such as a harness has a branch point where the harness branches. When protecting the wiring with a corrugated tube, it may be difficult to protect the wiring with the corrugated tube at the branch point due to the complex structure of the corrugated tube. Therefore, measures such as wrapping tape around the wiring are taken.

[0005] However, when wiring is attached to vehicle components that generate vibration, such as an engine or a transmission, there is a risk that the wiring at the branch point may come into contact with other components, such as a bracket, due to variations in component shape and assembly. If the wiring at the branch point comes into contact with other components, friction will occur at the contact points due to vibration, etc., leading to the risk of damaging the wiring. This is not limited to wiring, but also applies to piping that is routed to vehicle components.

[0006] The present invention was devised with an eye to the above-mentioned problems, and its object is to provide a bracket for wiring in a vehicle that can prevent linear members arranged in vehicle components such as wiring and piping from coming into contact with other components. [Means for solving the problem]

[0007] The present invention can be realized as the following application examples. The vehicle wiring bracket of this application example is a structure of a vehicle wiring bracket for attaching a linear member (including wiring and piping) and a protective member for the linear member to a vehicle part, and has a recess or a cut portion, and the recess or the cut portion is positioned at a branch point where the linear member is exposed from the protective member.

[0008] The wiring bracket of the vehicle in this application example has a recess or cut portion that is positioned at the branching point where the linear member is exposed from the protective member, thereby reducing the risk of the linear member exposed from the protective member coming into contact with the wiring bracket at the branching point. Effect of the Invention

[0009] According to the vehicle wiring bracket according to this application example, the risk of the linear member exposed from the protective member coming into contact with the wiring bracket is reduced, and the risk of the linear member being damaged can be suppressed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] The embodiment of the present invention will be described with reference to the drawings. This embodiment is merely an example, and is not intended to exclude various modifications or application of techniques not specified in the following embodiment. Each configuration of this embodiment can be modified in various ways without departing from the spirit of the invention. In addition, they can be selected or combined as necessary.

[0012] [1. Configuration] Fig. 2 is a schematic side view of an engine equipped with a wiring bracket of a vehicle according to an embodiment. As shown in Fig. 2, harnesses (wiring) 21-25 (in the case where they are not individually distinguished, they are indicated by the reference symbol 20) as linear members may be wired on a vehicle component (vehicle part) that generates vibration, such as an engine 1. In this case, various parts of the harness 20 are fixed with a number of bands 50 in order to fix the harness 20 appropriately along the complex component shape. At this time, the harness 20 is fixed at key points using guide brackets (wiring brackets) 30, 40.

[0013] Fig. 3(a) is an enlarged view of part A in Fig. 2, and Fig. 3(b) is a view corresponding to an enlarged view of part B in Fig. 2, which is a portion where the guide bracket 30 or a guide bracket 40 described below is used. As shown in Figs. 3(a) and (b), the harness 20 to be fixed is covered in advance with a corrugated tube (protective member) 60, and is fixed from the outside of the corrugated tube 60 with a band 50.

[0014] 3(a) and (b), the harnesses 20 are appropriately bundled, covered with a corrugated tube 60, and fixed with a band 50, but because the wiring destinations of the harnesses 20 are different, a branching section (or a junction) 70 occurs. At such a branching section 70, the harnesses 20 cannot be covered with the corrugated tube 60. At such a branching section 70 where the harnesses 20 cannot be covered with the corrugated tube 60, the harnesses 20 are generally protected by wrapping tape 80 around them.

[0015] 3 and 1, 4 and 5 described later, the area where the tape 80 is wound is shown with a dotted background pattern. In these figures, the harnesses 20 and the corrugated tubes 60 are shown broken in the middle, but as shown in FIG. 2, they extend to a point not shown.

[0016] In this embodiment, the harness 20 is fixed at key points including the branching portion 70 using the guide bracket 30 or a guide bracket 40 described below. The guide brackets 30, 40 have guide portions 31, 41 that are fixed to the engine 1 at fixing points (not shown) and are arranged along the wiring position of the harness 20. In the portion where the guide brackets 30, 40 are used, the harness 20 is arranged along the guide portions 31, 41 of the guide brackets 30, 40, and the harness 20 is fixed to the guide portions 31, 41 with a band 50.

[0017] As shown in Fig. 3(a), the harness 20 with the corrugated tube 60 may be fixed onto the guide bracket 30 by a band 50. Normally, the harness 20 at the branching portion 70 has a smaller diameter than the outer diameter of the corrugated tube 60, so that at the branching portion 70, there is a gap between the harness 20 and the linear guide portion 31 of the guide bracket 30 and the harness 20 does not come into direct contact with the guide portion 31. Therefore, even if the branching portion 70 is not protected by the corrugated tube 60, the harness 20 is unlikely to be damaged.

[0018] However, as shown in Fig. 3(b), there are cases where the wiring must be made to have a multi-branch at the branching portion 70, where three or more harnesses 20 branch out. In such cases, since each branch is covered with tape, the shape of the branching portion 70 varies depending on the product variation of the harness 20 itself and the variation in assembly to the vehicle. For this reason, as shown in Fig. 3(b), there are cases where the harnesses 20 cross each other, causing some harnesses (harnesses 23, 24) to ride up on other harnesses (harnesses 21, 22).

[0019] 3(b), a part of the harness 20 at the branching portion 70 may protrude beyond the outer diameter of the corrugated tube 60 and come into contact with the linear guide portion 31 of the guide bracket 30 without any protection (no gap between the guide bracket 30 and the harness 20). If the component (engine 1) vibrates in this contact state, friction and wear will occur between the guide bracket 30 and the tape 80 and the wire coating, which may damage the harness 20.

[0020] Therefore, in this embodiment, at the multiple branching points of the harness 20 where there is a risk of wear occurring in the harness 20, a guide bracket 40 having the structure shown in FIG. 1 is used instead of the guide bracket 30. The guide bracket 40 has a recess 42 at the middle of a guide portion 41 that is disposed along the wiring position of the harness 20 and is spaced apart from the harness 20. The recess 42 is disposed at a position corresponding to a branch portion 70 where the harness 20 is exposed from the corrugated tube 60 and is covered only with the tape 80.

[0021] In this embodiment, the recess 42 is composed of bent portions 44a, 44b bent in a direction away from the harness 20 with respect to both end portions 43a, 43b of the guide portion 41, and a separation portion 45 located between the bent portions 44a, 44b. Both end portions 43a, 43b and the separation portion 45 are disposed parallel to the wiring direction of the harness 20.

[0022] [2. Actions and Effects] As described above, the guide bracket 40 according to this embodiment has the recess 42 separated from the harness 20 in the middle of the guide portion 41 that is disposed so as to follow the wiring position of the harness 20, and the recess 42 is disposed at a location corresponding to the branch portion 70 that is covered only with the tape 80. Therefore, the recess 42 separates the guide portion 41 of the guide bracket 40 from the branch portion 70.

[0023] Therefore, as described above, even if the branch portion 70 is multi-branched and a part of the harness 20 at the branch portion 70 protrudes beyond the outer diameter of the corrugated tube 60, the risk of the branch portion 70, which is covered only with the tape 80, coming into contact with the guide portion 41 of the guide bracket 40 is reduced. This reduces the risk of damage to the harness 20 due to friction and wear between the guide bracket 40 and the tape 80 and the wire coating.

[0024] [3. Modifications] Below, modified examples of the guide bracket 40 will be described.

[0025] [3.1. First modified example] FIG. 4 is a view showing a guide bracket 40A according to a first modified example. 4, in this guide bracket 40A, the recess 42A of the guide portion 41A of the guide bracket 40A is configured by a curved portion that is curved in a curved shape relative to both end portions 43a, 43b of the guide portion 41A in a direction away from the harness 20. The recess 42A is disposed at a position corresponding to the branch portion 70 that is covered only with the tape 80. In this structure as well, the risk of the branch portion 70 coming into contact with the guide portion 41A of the guide bracket 40A is reduced, similarly to the embodiment.

[0026] [3.2. Second Modification] FIG. 5 is a view showing a guide bracket 40B according to a second modified example. As shown in Figure 5, similar to the embodiment, this guide bracket 40B is composed of bent portions 44c, 44d in which the recess 42B of the guide portion 41B of the guide bracket 40B is bent in a direction away from the harness 20 relative to both end portions 43c, 43d of the guide portion 41B, and a separating portion 45a located between the bent portions 44c, 44d and parallel to the harness 20 and both end portions 43c, 43d.

[0027] However, in this modification, both ends 43c, 43d of the guide portion 41B are arranged with each edge inclined in a direction away from the branch portion 70, and the harness 20 guided by both ends 43c, 43d is also arranged bent in a direction away from the branch portion 70. In other words, by using the guide bracket 40B according to the second modification, the branch portion 70 can be separated from the separation portion 45a of the guide bracket 40C without significantly shifting the separation portion 45a in a direction away from the branch portion 70. This modified example is effective when there is no space to recess the separation portion 45a in a direction away from the branching portion 70 due to the presence of other components 90, and similar to the embodiment, the risk of the branching portion 70 coming into contact with the guide portion 41B of the guide bracket 40B is reduced.

[0028] [3.3. Third Modification] FIG. 6 is a view showing a guide bracket 40C according to a third modified example. 6, the guide bracket 40C includes a cut portion 42C formed by removing a middle portion of a guide portion 41C of the guide bracket 40C. The cut portion 42C is disposed at a position corresponding to the branch portion 70 that is covered only with the tape 80. In this structure as well, the risk of the branch portion 70 coming into contact with the guide portion 41C of the guide bracket 40C is reduced, similarly to the embodiment.

[0029] [4.Other] The above-described embodiment is merely an example, and each configuration of the above-described embodiment can be modified in various ways without departing from the spirit of the embodiment. In addition, some of the elements can be selected as necessary, or can be combined with other known techniques.

[0030] For example, in the above embodiment, the guide brackets 30, 40 are used at the two branching portions 70, but the guide brackets 30, 40 may be used in places other than the branching portions 70. In addition, in each of the above embodiments, the engine 1 is given as an example of a component that generates vibration and is the wiring target of the harness 20, but the present invention is not limited to this. A vehicle may have other components in addition to the engine 1, such as a transmission, and the wiring bracket may be applied to any of these components. Furthermore, in the above embodiment, the harness (wiring) 20 is exemplified as a linear member, but the linear member may be any linear member that is arranged in a vehicle component, and may also include, for example, piping.
