[0008] Figure 1 This is a schematic structural diagram of a wire harness and a wire fixing member in one embodiment. Figure 2 This is a schematic side view of a wire harness and a wire fixing member in one embodiment. Figure 3 It is along Figure 2 Cross-sectional view along line 3-3. Figure 4This is a cross-sectional view of a wire harness and a wire fixing member in another example. DETAILED DESCRIPTION

[0009] [Description of Embodiments of the Invention] First, embodiments of the present invention will be described below. The electric wire fixing member of the present invention, [1] A wire harness arranged below an installation object is fixed to the installation object, wherein the wire fixing member includes a supporting member, the supporting member comprising: a plate-shaped supporting plate portion extending along an extension direction of the wire harness and capable of supporting the wire harness from below; and a fixing portion provided at a plurality of locations in the extension direction of the supporting plate portion, extending upward from the supporting plate portion and capable of being fixed to the installation object.

[0010] According to this structure, the supporting member of the wire securing member comprises a plate-shaped supporting plate portion extending in the direction in which the wire harness extends; and fixing portions provided at multiple locations in the extending direction of the supporting plate portion, extending upward from the supporting plate portion. The fixing portions are secured to the mounting object, and the wire harness is supported by the supporting plate portion. This simple structure prevents the wire harness from sagging.

[0011] [2] In the above [1], a holding and fixing member may be provided, the holding and fixing member holding a portion of the wire harness in the extending direction and being fixed to the support plate portion. According to this configuration, since the holding and fixing member is provided, and the holding and fixing member holds a portion of the wire harness in the extending direction and is fixed to the support plate portion, it is possible to prevent the wire harness from falling off the support plate portion.

[0012] [3] In the above [1] or [2], the fixing portion may include a first fixing portion and a second fixing portion, the first fixing portion extending upward from a first end portion in the width direction of the support plate portion, the second fixing portion extending upward from a second end portion in the width direction of the support plate portion, and the first fixing portion and the second fixing portion being alternately arranged in the extension direction of the support plate portion.

[0013] According to this structure, since the first fixing portions extending upward from the first widthwise end of the support plate and the second fixing portions extending upward from the second widthwise end of the support plate are alternately arranged along the extension direction of the support plate, the posture of the support plate is stabilized. Specifically, in a structure where the fixing portions are provided only at the first widthwise end of the support plate, the support plate may deflect with the second end facing downward, but this deflection is suppressed. Consequently, sagging of the wiring harness can be stably prevented.

[0014] [4] In the above [1] or [2], the fixing portion may be provided only at one end portion in the width direction of the support plate portion. According to this structure, the fixing portion is provided only at one end portion of the support plate in the width direction, so that, for example, it can be arranged in a smaller arrangement space. In other words, for example, in a structure in which the fixing portion is provided at both ends of the support plate in the width direction, sometimes fixing space is required on both sides of the support plate in the width direction, but this situation can be avoided.

[0015] [5] In any one of the above [1] to [4], the support member may include a side wall portion extending upward from an end portion in the width direction of the support plate portion. According to this configuration, the support member includes the side wall portion extending upward from the end portion in the width direction of the support plate portion, and thus it is possible to suppress the wire harness from falling off the support plate portion.

[0016] [6] In the above [5], the fixing portion may be provided only at the first end portion in the width direction of the support plate portion, and the side wall portion may be provided only at the second end portion in the width direction of the support plate portion.

[0017] According to this structure, since the fixing portion is provided only at the first end portion in the width direction of the support plate portion, it can be placed in a relatively small space, for example. Furthermore, since the side wall portion is provided only at the second end portion in the width direction of the support plate portion, the wiring harness can be prevented from falling off the second end portion of the support plate portion. Furthermore, the fixing portion extending upward from the support plate portion prevents the wiring harness from falling off the first end portion of the support plate portion.

[0018] [Details of Embodiments of the Invention] Specific examples of the wire fixing member of the present invention are described below with reference to the accompanying drawings. In each of the drawings, for ease of explanation, a portion of the structure is sometimes enlarged or simplified. In addition, the dimensional ratios of the various parts may sometimes differ in the various drawings. The terms "parallel," "orthogonal," or "perfect circle" in this specification include not only strictly parallel, orthogonal, or perfect circles, but also approximately parallel, orthogonal, or perfect circles within the scope of the effects of the present embodiment. In addition, the present invention is not limited to these examples, but is shown in the claims, and is intended to include all variations within the meaning and scope equivalent to the claims.

[0019] (Overall Structure of Wiring Harness 10) Figure 1The illustrated wire harness 10 electrically connects two or more electrical devices. For example, the wire harness 10 electrically connects an inverter 11 located at the front of a vehicle V, such as a hybrid vehicle or electric vehicle, and a high-voltage battery 12 located further rearward of the vehicle V than the inverter 11. The wire harness 10 is routed, for example, so as to pass beneath the floor of the vehicle V. For example, the longitudinal middle portion of the wire harness 10 is routed so as to pass beneath the underfloor panel P, to which it is installed, i.e., outside the vehicle cabin.

[0020] The inverter 11 is connected to an electric motor (not shown) that drives the wheels and serves as the vehicle's power source. The inverter 11 generates AC power from DC power from a high-voltage battery 12 and supplies this AC power to the electric motor. The high-voltage battery 12 can, for example, supply a voltage of several hundred volts.

[0021] like Figure 2 and Figure 3 As shown, the wire harness 10 includes a plurality of electric wires 20 for electrically connecting the above-mentioned electrical devices to each other, and a corrugated tube 30 as an exterior member that covers the outer periphery of the electric wires 20 .

[0022] (Structure of the Electric Wire 20) like Figure 3 As shown, the wire harness 10 of this embodiment includes two electric wires 20. The electric wires 20 have a core wire 21 and an insulating coating 22 covering the outer periphery of the core wire 21.

[0023] The core wire 21 is composed of, for example, a stranded wire obtained by twisting a plurality of conductive wires, a single core wire, etc. The core wire 21 is composed of, for example, a metal material such as copper or aluminum.

[0024] The insulating coating 22 covers, for example, the entire outer peripheral surface of the core wire 21. The insulating coating 22 is made of an insulating material such as a synthetic resin mainly composed of a polyolefin resin such as cross-linked polyethylene or cross-linked polypropylene.

[0025] (Structure of the bellows 30) The corrugated tube 30 is cylindrical. It has a corrugated structure with large-diameter portions and smaller-diameter portions alternately connected along the length of the corrugated tube 30. The corrugated structure is omitted in the figure, and the corrugated tube 30 is schematically illustrated. The corrugated structure makes the corrugated tube 30 flexible and easily bendable. The material of the corrugated tube 30 can be synthetic resins such as polyolefin, polyamide, polyester, and ABS resin. The corrugated tube 30 collectively covers the two wires 20, protecting them.

[0026] (Structure of the Wire Fixing Member 40) like Figure 2 and Figure 3As shown, the wire fixing member 40 fixes the wire harness 10 routed below the floor under panel P to the floor under panel P. The wire fixing member 40 includes a support member 50 and a band clamp 60 as a holding and fixing member.

[0027] (Structure of Support Member 50) The support member 50 includes a support plate portion 51 and first and second fixing portions 52 and 53. The support member 50 is made of a metal material. The support plate portion 51 is formed into a plate shape extending in the direction in which the wire harness 10 extends and capable of supporting the wire harness 10 from below.

[0028] The first fixing portion 52 and the second fixing portion 53 are provided at multiple locations in the extension direction of the support plate portion 51, extend upward from the support plate portion 51, and can be fixed to the floor underpanel P. In detail, the first fixing portion 52 extends upward from the first end portion 51a in the width direction of the support plate portion 51. The first fixing portion 52 has a first upper extension portion 52a extending upward from the first end portion 51a and a first fixing piece 52b extending from the upper end of the first upper extension portion 52a to the outside in the width direction. In addition, the second fixing portion 53 extends upward from the second end portion 51b in the width direction of the support plate portion 51. The second fixing portion 53 has a second upper extension portion 53a extending upward from the second end portion 51b and a second fixing piece 53b extending from the upper end of the second upper extension portion 53a to the outside in the width direction. In addition, the width direction of the support plate portion 51 is a direction intersecting the extension direction of the support plate portion 51, which is Figure 3 The first fixing portion 52 is fixed to the underfloor panel P by a bolt B that passes through the first fixing piece 52b and is screwed into an internally threaded hole Pa formed in the underfloor panel P. The second fixing portion 53 is fixed to the underfloor panel P by a bolt B that passes through the second fixing piece 53b and is screwed into an internally threaded hole Pa formed in the underfloor panel P.

[0029] like Figure 2 As shown, the first fixing portions 52 and the second fixing portions 53 are separated and alternately arranged in the extending direction of the support plate portion 51. In this embodiment, a total of four first fixing portions 52 and second fixing portions 53 are provided at equal intervals between the two end portions in the extending direction of the support plate portion 51.

[0030] (Structure with clamping member 60) The band clamp 60 holds a portion of the wire harness 10 in its extended direction and is secured to the support plate 51. The band clamp 60 includes a flexible, soft band portion 61, a locking portion 62 provided at the longitudinal end of the band portion 61, and a latching portion 63 provided on the locking portion 62. When the band portion 61 is inserted, the locking portion 62 restricts movement of the band portion 61 in the removal direction, which is the opposite direction of the insertion direction, thereby locking the band portion 61. The band clamp 60 holds a portion of the wire harness 10 in its extended direction by inserting the locking portion 62 while the band portion 61 covers the entire circumference of the corrugated tube 30. Furthermore, the latching portion 63 engages with a latching hole 51c provided in the support plate 51, securing the band clamp 60 to the support plate 51.

[0031] The belt clamps 60 are respectively arranged between the first fixing portion 52 and the second fixing portion 53 in the extending direction of the support plate portion 51. That is, the belt clamps 60 are provided between each of the first fixing portion 52 and the second fixing portion 53, which are provided four in total. In addition, Figure 2 In FIG, the wire harness 10 is schematically shown in a straight line shape, but depending on the slack state and the like, the wire harness 10 partially contacts the support plate portion 51 and is supported thereby.

[0032] Next, the operation of the electric wire fixing member 40 configured as described above will be described. The wire harness 10 is secured to the underfloor panel P via a wire securing member 40. Since the wire harness 10 is supported from below by a support plate portion 51 extending in the direction in which the wire harness 10 extends, a portion of the wire harness 10 in the direction in which it extends is prevented from sagging below the support plate portion 51. Furthermore, since the ground side of the wire harness 10 is covered by the support plate portion 51, for example, collision with foreign objects from the ground side is prevented.

[0033] Next, the effects of the above-described embodiment will be described below. (1) The support member 50 included in the wire securing member 40 includes a plate-shaped support plate portion 51 extending in the direction in which the wire harness 10 extends, and first and second fixing portions 52, 53 provided at multiple locations in the direction in which the support plate portion 51 extends and extending upward from the support plate portion 51. The first and second fixing portions 52, 53 are secured to the underfloor panel P, and the wire harness 10 is supported by the support plate portion 51. Thus, the wire harness 10 can be prevented from sagging with a simple structure.

[0034] (2) The wire fixing member 40 includes the band clamp 60 . The band clamp 60 holds a portion of the wire harness 10 in the extending direction and is fixed to the support plate 51 . This prevents the wire harness 10 from falling off the support plate 51 .

[0035] (3) The first fixing portion 52 extending upward from the first end portion 51a in the width direction of the support plate portion 51 and the second fixing portion 53 extending upward from the second end portion 51b in the width direction of the support plate portion 51 are alternately arranged in the extension direction of the support plate portion 51. Therefore, the posture of the support plate portion 51 is stable. That is, for example, in a structure in which the fixing portion is provided only at the first end portion 51a in the width direction of the support plate portion 51, the support plate portion 51 may bend in a manner such that the second end portion 51b side faces downward, but the bending of the support plate portion 51 can be suppressed. Therefore, the wire harness 10 can be stably prevented from sagging.

[0036] This embodiment can be implemented as the following modifications: This embodiment and the following modifications can be implemented in combination with each other within a range that does not technically conflict. In the above embodiment, the support member 50 includes the first fixing portion 52 and the second fixing portion 53 as fixing portions. However, the present invention is not limited thereto. For example, the support member 50 may not include either the first fixing portion 52 or the second fixing portion 53. In other words, the support member 50 may be provided only at one end portion in the width direction of the support plate portion 51.

[0037] For example, Figure 4 As shown, the support member 70 may also include only the first fixing portion 52 as a fixing portion. In this case, for example, it can be arranged in a smaller space. For example, in a structure where the fixing portions are provided at both ends of the support plate portion 51 in the width direction, sometimes fixing space is required on both sides of the support plate portion 51 in the width direction. However, this can be avoided.

[0038] In the above embodiment, the wire fixing member 40 includes the band clamp 60 that holds a portion of the wire harness 10 in the extending direction and is fixed to the support plate portion 51 . However, the present invention is not limited thereto and may be configured without the band clamp 60 .

[0039] For example, you can also Figure 4 In this example, the wire harness 10 is in contact with the support plate portion 51 and supported by the support plate portion 51 in the entire extending direction. The support members 50 and 70 of the above-described embodiment may include side wall portions extending upward from the widthwise end portions of the support plate portion 51 .

[0040] For example, Figure 4As shown, the support member 70 may also be configured to include only the first fixing portion 52 and the side wall portion 71 only at the second end portion 51b in the width direction of the support plate portion 51. In this case, the support member 70 includes the side wall portion 71 extending upward from the end portion in the width direction of the support plate portion 51, thereby preventing the wire harness 10 from falling off the support plate portion 51. In addition, in this example, the fixing portion is the first fixing portion 52 provided only at the first end portion 51a in the width direction of the support plate portion 51, and the second fixing portion 53 is not provided. Therefore, for example, it can be arranged in a smaller configuration space. In addition, since the side wall portion 71 is provided only at the second end portion 51b in the width direction of the support plate portion 51, it can prevent the wire harness 10 from falling off the second end portion 51b of the support plate portion 51. Furthermore, the first fixing portion 52 extending upward from the support plate portion 51 prevents the wire harness 10 from falling off the first end portion 51a of the support plate portion 51. The side wall portion 71 may be provided over the entire portion or partially over the extending direction of the support plate portion 51. Alternatively, the side wall portion 71 may be provided at the first end portion 51a.

[0041] In the above embodiment, the electric wire fixing member 40 is configured to include only one supporting member 50 , but the present invention is not limited thereto and may be configured to include two or more supporting members 50 in the extending direction of the wire harness 10 .

[0042] In the above embodiment, the bolts B that fix the first fixing portion 52 and the second fixing portion 53 are screwed into the internal threaded holes Pa formed in the underfloor panel P. However, the present invention is not limited thereto and, for example, the bolts B may be screwed into nuts disposed above the underfloor panel P.

[0043] In the above embodiment, the first fixing portion 52 and the second fixing portion 53 include the first fixing piece 52b and the second fixing piece 53b fixed by the bolts B. However, the present invention is not limited thereto and the first fixing portion 52 and the second fixing portion 53 may be fixed to the underfloor panel P using other structures.

[0044] In the above embodiment, the installation target is the underfloor panel P of the vehicle V, but the present invention is not limited thereto. The underfloor panel P may be another installation target under which the wire harness 10 is routed.

[0045] In the above embodiment, the wire harness 10 includes the corrugated tube 30, but the present invention is not limited thereto and may be configured without the corrugated tube 30. Furthermore, the corrugated tube 30 may be replaced with another exterior member such as a flexible hose.

[0046] In the above embodiment, the wire harness 10 includes two electric wires 20 , but the present invention is not limited thereto and may include only one electric wire 20 or three or more electric wires 20 .

[0047] The wire harness 10 of the above embodiment may include an electromagnetic shield member that covers the outer periphery of the electric wires 20 and is covered by the corrugated tube 30. As the electromagnetic shield member, for example, a braided wire obtained by braiding conductive wires into a cylindrical shape can be used.

[0048] ·exist Figure 3 、 4 In the illustrated non-limiting embodiment, the support plate portion 51 of the support member 50 can have a length corresponding to the predetermined length of the portion of the wire harness 10 excluding both ends. The support plate portion 51 can be configured to restrict downward warping of the wire harness 10 in the direction of gravity along the length of the support member 50 and is sometimes referred to as a bottom plate. For example, it can be a flat plate. The upper surface of the support plate portion 51 of the support member 50 is sometimes referred to as the bottom surface that supports the wire harness 10 and / or the belt clamp 60 from below. Figure 3 The first upward extension portion 52a and the second upward extension portion 53a of the support member 50 of the non-limiting embodiment shown can be configured to cooperate to limit the horizontal displacement of the wire harness 10. For example, the first upward extension portion 52a and the second upward extension portion 53a are Figure 3 The middle can be configured to limit the displacement to the left and the displacement to the right, and sometimes they are referred to as the first side stopper plate and the second side stopper plate, respectively, and both can be flat plates. Figure 4 The same applies to the first upward extending portion 52 a and the side wall portion 71 of the non-limiting embodiment shown.

[0049] In the non-limiting embodiment shown in the figures, the support member 50 may be a one-piece member, for example, a one-piece metal member. Description of Reference Numerals
