[0009] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. However, the present invention is not limited to these embodiments. Furthermore, the components in the following embodiments include those that are easily replaceable by those skilled in the art, or those that are substantially the same.

[0010] [Embodiment] This embodiment relates to a fixing device. In the following description, of the first, second, and third directions that intersect with each other, the first direction is referred to as the "connection direction X," the second direction is referred to as the "extension direction Y," and the third direction is referred to as the "height direction Z." Here, the connection direction X, the extension direction Y, and the height direction Z are mutually perpendicular. The connection direction X corresponds to the direction in which the fixing device is connected to the object to be fixed. The extension direction Y corresponds to the direction in which the electric wires extend. Furthermore, unless otherwise specified, each direction used in the following description represents the direction in which each part is assembled to each other. Note that orthogonal here includes nearly orthogonal.

[0011] 1 and 2 show a fixing device 1 according to this embodiment. Fig. 2 is a cross-sectional view of the fixing device 1 taken along line II-II in Fig. 1.

[0012] As shown in FIGS. 1 and 2 , the fixing device 1 is a device or unit that fixes an electric wire 10 to an object 90, and is mounted on, for example, a vehicle for use. The fixing device 1 is attached to the electric wire 10 and fixed to the object 90, and fixes the electric wire 10 to the object 90. The fixing device 1 forms part of a wire harness when attached to the electric wire 10. In other words, the electric wire 10 and the fixing device 1 form the wire harness. The electric wire 10 may be a single electric wire, or may be provided as an electric wire bundle formed by bundling multiple electric wires. Furthermore, the electric wire 10 may be, for example, an electric wire bundle formed by bundling multiple electric wires and having a tape, a tube, a protector, or the like wrapped around the outer periphery thereof.

[0013] The object to be fixed 90 may be a vehicle body, or a member or part attached to the vehicle body. The object to be fixed 90 may be, for example, a vehicle body manufactured by large-scale casting using Gigacast. More specifically, the object to be fixed 90 is an aluminum die-cast, such as an aluminum alloy die-cast such as ADC1, ADC3, ADC5, ADC6, ADC10, ADC10Z, ADC12, ADC12Z, ADC14, or ADT10-F. The object to be fixed 90 has a portion to be fixed 91. The portion to be fixed 91 is a plate-like portion formed on the object to be fixed 90, and may be, for example, a protruding portion protruding from a surface 90A of the object to be fixed 90. The portion to be fixed 91 is formed as a plate without any fixing holes, and may, for example, be longer in the extension direction Y than in the height direction Z, and have a rectangular cross-sectional shape intersecting the connection direction X. The fixed portion 91 may have a shape other than a plate shape, such as a rod shape, and the cross section of the fixed portion 91 may have a shape other than a rectangle.

[0014] The fixing device 1 includes an electric wire attachment portion 2 and a fixing portion 3. The electric wire attachment portion 2 is a portion that is attached to the electric wire 10, and includes, for example, a joint portion 21 and a bundling portion 22. The joint portion 21 is formed, for example, in a block shape, and is joined to the fixing portion 3. The bundling portion 22 is a band member and has a length that allows it to be wound around the outer circumference of the electric wire 10. The base end side of the bundling portion 22 is fixed to the joint portion 21, and the tip side is engageable with the joint portion 21. The bundling portion 22 attaches the fixing device 1 to the electric wire 10 by winding the electric wire 10 around it and engaging the tip portion with the joint portion 21. The electric wire attachment portion 2 may have a structure other than that described above, as long as it is possible to attach the fixing device 1 to the electric wire 10.

[0015] The fixing portion 3 is a portion that fixes the object 90 to be fixed, and is formed, for example, from resin. By forming the fixing portion 3 from resin, damage to the object 90 to be fixed when fixing to the object 90 is suppressed. The fixing portion 3 has a main body 31 and a protrusion 32. The main body 31 is a portion through which the object 91 to be fixed is inserted and held, and is formed into a box shape by joining multiple wall portions 311. For example, the main body 31 has four wall portions 311, and is formed into a cylindrical shape with a rectangular cross section by joining the ends of adjacent wall portions 311 to each other. The main body 31 has an insertion hole 312 formed inside the wall portions 311.

[0016] The insertion hole 312 is a hole through which the fixed portion 91 is inserted to hold or fix the fixed portion 91, and is formed along the connection direction X. The insertion hole 312 is formed to penetrate the main body 31 along the connection direction X, and is configured so that the tip 91A of the inserted fixed portion 91 protrudes from the main body 31. That is, in the connection direction X, the length L2 of the insertion hole is formed to be shorter than the length L1 of the fixed portion 91. Therefore, the fixed portion 91 can pass through the insertion hole 312. When the fixed portion 91 is inserted into the insertion hole 312 of the main body 31 of the fixing part 3, the tip 91A of the fixed portion 91 protrudes from the main body 31, so that the fixing device 1 can confirm that the fixing part 3 is firmly fixed to the fixed portion 91.

[0017] The protrusion 32 is a protrusion that protrudes from the wall surface 311A ​​of the wall portion 311 into the insertion hole 312, and is formed, for example, with a mountain-shaped cross section with a tapered tip. The wall surface 311A ​​is the inner surface, or inside surface, of the wall portion 311. The protrusion 32 is a portion that presses the fixed portion 91 inserted into the insertion hole 312, and is provided, for example, on the wall surface 311A ​​of the wall portion 311 that faces the main surface 91B of the fixed portion 91. The protrusion 32 is formed, for example, as a ridge that extends along the connection direction X of the insertion hole 312, and is provided at the center of the wall surface 311A ​​in the extension direction Y.

[0018] 3, thickness T of fixed portion 91 is smaller than distance D1 between opposing wall surfaces 311A ​​and is larger than distance D2 between the tip of protrusion 32 and wall surface 311A. Therefore, when fixed portion 91 is inserted into insertion hole 312, fixed portion 91 is pressed into insertion hole 312 while being pressed by protrusion 32.

[0019] Next, the fixing of the fixing device according to this embodiment will be described.

[0020] As shown in Fig. 1, the fixing device 1 is attached to the electric wire 10 by the electric wire attaching part 2. At this time, the electric wire attaching part 2 is attached so that the fixing device 1 is located at the position of the fixed part 91 when the electric wire 10 is routed.

[0021] The fixing device 1 is then arranged so that the fixing portion 3 faces the fixed portion 91. The fixing portion 3 is then brought close to the fixed portion 91 so that the fixed portion 91 is inserted into the insertion hole 312.

[0022] The fixed portion 91 is inserted into the insertion hole 312. At this time, as shown in FIG. 5 , the fixed portion 91 is press-fitted into the insertion hole 312 while being pressed by the protrusion 32. At this time, as the fixed portion 91 is press-fitted into the insertion hole 312, the wall portion 311 forming the protrusion 32 is elastically deformed. That is, the protrusion 32 applies a reaction force to the wall portion 311 to strongly press and hold the fixed portion 91. Furthermore, the wall portion 311 forming the protrusion 32 is joined to the adjacent wall portions 311 and is restrained from moving, so that the protrusion 32 can be strongly pressed against the fixed portion 91. At this time, because the fixing portion 3 and the protrusion 32 are made of resin, damage to the fixed portion 91 can be prevented. Therefore, the fixing device 1 can prevent the fixed portion 91 from being damaged while the fixing portion 3 strongly presses the fixed portion 91, and can properly fix the fixed portion 91. Furthermore, since the fixing device 1 can fix the fixed portion 91 by inserting it through the insertion hole 312, the fixing portion 3 can be made small, and the entire device can be made smaller. Therefore, the fixing device 1 can fix the electric wire 10 in a space-saving manner.

[0023] Then, as shown in FIG. 4 , the fixed portion 91 penetrates the main body 31 of the fixing portion 3, with the tip 91A protruding from the main body 31. As a result, the fixing portion 3 is fixed to the fixed portion 91, the fixing device 1 is fixed to the object 90, and the electric wire 10 is fixed to the object 90 through the fixing device 1. At this time, by confirming that the tip 91A of the fixed portion 91 protrudes from the main body 31 of the fixing portion 3, it can be visually confirmed that the fixing device 1 is securely fixed to the object 90. For example, even if the fixed portion 91 is inserted into the fixing portion 3, if the tip 91A of the fixed portion 91 does not protrude from the fixing portion 3, it can be confirmed that the insertion of the fixed portion 91 is insufficient. In this case, by inserting the fixed portion 91 again so that it penetrates the fixing portion 3, the fixing by the fixing device 1 can be properly performed.

[0024] The fixing device 1 can fix the object 90 to the fixing target 90 by inserting the object 90 through the fixing portion 3. Therefore, the fixing device 1 can fix the object 90 even if no fixing hole is formed in the fixing target portion 91. Therefore, the fixing device 1 is suitable for fixing the object 90 to be fixed that is manufactured by Gigacast.

[0025] As described above, the fixing device 1 of this embodiment is provided with a fixing part 3 that is inserted into and holds the fixed part 91 of the fixed object 90, thereby allowing the fixing part 3 to be properly fixed to the fixed part 91 and the electric wire 10 to be fixed to the fixed object 90.

[0026] Furthermore, the fixing device 1 of this embodiment fixes the fixed portion 91 by passing it through the fixing portion 3 and causing the tip 91A of the fixed portion 91 to protrude from the fixing portion 3, making it easy to confirm that the fixing has been performed properly by the fixing portion 3.

[0027] Furthermore, the fixing device 1 according to this embodiment elastically deforms the wall portion 311 with the fixed portion 91 inserted through the insertion hole 312, pressing the protrusion 32 against the fixed portion 91 to hold the fixed portion 91. Therefore, the fixing device 1 can firmly hold and fix the fixed portion 91 while preventing the fixed portion 91 from being damaged.

[0028] The fixing device according to the present invention is not limited to the above-described embodiment, and various modifications are possible within the scope of the claims. The fixing device according to the embodiment may be configured by appropriately combining the components of the above-described embodiment and modified examples.

[0029] For example, in the above-described embodiment, the fixing device 1 is mounted on a vehicle, but the fixing device according to the present invention may be used without being mounted on a vehicle. [Explanation of symbols]
