[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 a first 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 90 may be a vehicle body or a member or part attached to the vehicle body. The object 90 may be, for example, a vehicle body manufactured by large-scale casting using Gigacast. More specifically, the object 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 90 has a fixed portion 91. The fixed portion 91 is a plate-like portion formed on the object 90, and is formed, for example, protruding from a surface 90A of the object 90. The fixed portion 91 is formed as a plate without any fixing holes. In FIG. 1 , the fixed portion 91 is a single plate, but it may be a plurality of plates arranged in the extension direction Y, or a plate with protrusions or projections on its surface. By providing a ridge or protrusion on the surface of the fixed portion 91, the fixing by the fixing device 1 can be performed more firmly.

[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 main body 21 and a binding portion 22. The main body 21 is a plate extending along the extension direction Y, and is disposed along the extension direction Y of the electric wire 10. The binding portion 22 is provided by winding the electric wire 10 together with the main body 21, and is a member that attaches the fixing device 1 to the electric wire 10. For example, a tape is used as the binding portion 22. Note that the binding portion 22 may be a member other than a tape, such as a band. Furthermore, 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 part 3 is a part that fixes the fixing part 3 to the fixing target 90 and is provided integrally with the electric wire attaching part 2. The fixing part 3 has a base part 31 and a cover part 32 and is fixed to the fixing target 90 by adhesive force. The base part 31 is joined to the main body 21 of the electric wire attaching part 2. The base part 31 and the cover part 32 are formed in a plate shape and sandwich the fixing target 91 between them to fix the fixing part 3. The cover part 32 is a movable part that is provided so as to be movable toward and away from the base part 31, and sandwiches the fixing target 91 between itself and the base part 31 when it is close to the base part 31. For example, the cover part 32 is provided so as to be rotatable relative to the base part 31 around a position near the electric wire attaching part 2. Specifically, a hinge part 33 is provided at the base end position of the cover part 32. The hinge part 33 is a hinge that rotatably supports the cover part 32. The cover part 32 is rotatable by the hinge part 33 about an axis extending in the extension direction Y. When the cover part 32 is rotated to a position away from the base part 31 in the open state, the fixing part 3 positions the fixed part 91 between the cover part 32 and the base part 31, and when the cover part 32 is rotated to a position close to the base part 31 in the closed state, the fixing part 3 sandwiches the fixed part 91 between the base part 31 and the cover part 32.

[0016] The base portion 31 has a main body portion 311 and an adhesive portion 312. The main body portion 311 is provided as a plate body. The adhesive portion 312 is provided on the inside of the main body portion 311, and is provided at a position where it comes into contact with the fixed portion 91. For the adhesive portion 312, an adhesive such as butyl rubber is used, for example. Furthermore, the adhesive portion 312 may use an adhesive other than butyl rubber as long as it can fix the fixing device 1 to the fixed portion 91. The adhesive portion 312 fixes or adheres anything it comes into contact with by its adhesive force.

[0017] The cover part 32 has a main body part 321 and an adhesive part 322. The main body part 321 is provided as a plate body. The adhesive part 322 is provided on the inside of the main body part 321, and is provided at a position where it comes into contact with the fixed part 91. For the adhesive part 322, an adhesive such as butyl rubber is used, for example. Furthermore, the adhesive part 322 may use an adhesive other than butyl rubber as long as it can fix the fixing device 1 to the fixed part 91. The adhesive part 322 fixes or adheres anything it comes into contact with by its adhesive force.

[0018] 3, adhesive portion 312 and adhesive portion 322 are formed to be larger than the insertion range of fixed portion 91 when fixed portion 91 is sandwiched between base portion 31 and cover portion 32. As a result, adhesive portion 312 and adhesive portion 322 come into contact with each other while in contact with fixed portion 91. Therefore, adhesive portion 312 and adhesive portion 322 are strongly bonded together, and separation of base portion 31 and cover portion 32 is suppressed.

[0019] Next, a fixing method for the fixing device 1 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] 2, the fixing part 3 is brought into an open state in which the base part 31 and the cover part 32 are separated from each other, and is brought close to the fixing part 91 so that the fixing part 91 is positioned between the base part 31 and the cover part 32. Then, the base part 31 is positioned below the fixing part 91, and the cover part 32 is rotated to sandwich the fixing part 91 between the cover part 32 and the base part 31.

[0022] 3, the fixed portion 91 is sandwiched between the base portion 31 and the cover portion 32. At this time, the adhesive portions 312 and 322 are adhered to and fixed to the surface of the fixed portion 91. The adhesive portions 312 and 322 are also in contact with and fixed to each other, which prevents the base portion 31 and the cover portion 32 from separating.

[0023] As a result, the fixing device 1 is fixed to the object 90 by the fixing portion 3, and can fix the electric wire 10 to the object 90. The fixing device 1 is fixed to the object 91 by the adhesive force of the adhesive portion 312 and the adhesive portion 322, so that the fixing can be performed appropriately without damaging the object 91. Furthermore, the fixing device 1 can perform fixing even if no hole is formed in the object 91. Therefore, the fixing device 1 is suitable for fixing to the object 90 manufactured by Gigacast.

[0024] As described above, the fixing device 1 according to the first embodiment is provided with a fixing part 3 having adhesive parts 312 and 322, and thereby fixes the fixing device 1 to the fixing object 90 by adhesive force. Therefore, fixing can be performed on fixing objects 90 that do not have fixing holes formed therein, and fixing can be performed appropriately without damaging the fixing object 90.

[0025] Next, a fixing device 1A according to a second embodiment will be described.

[0026] As shown in FIG. 4, the fixing device 1A according to the second embodiment is configured in almost the same manner as the fixing device 1 according to the first embodiment described above, but differs in that the fixing portion 3 is provided with a locking mechanism 4.

[0027] The locking mechanism 4 is a mechanism that restricts separation between the base portion 31 and the cover portion 32 when the base portion 31 and the cover portion 32 sandwich the fixed object 90, and has a locking portion 41 and a locked portion 42. The locking portion 41 is provided on the base portion 31. For example, the locking portion 41 is provided on an end portion of the main body portion 311 of the base portion 31 in the extension direction Y, and is formed as a protrusion that protrudes in the extension direction Y. The locked portion 42 is provided on the cover portion 32. For example, the locked portion 42 is provided on an end portion of the main body portion 321 of the cover portion 32 in the extension direction Y, and is formed as a member that forms a hole 421 that penetrates in the extension direction Y. When the base portion 31 and the cover portion 32 are closed, the locking portion 41 fits into the hole 421 of the locked portion 42, thereby entering a locked state and restricting separation between the base portion 31 and the cover portion 32. The locking portion 41 may be provided on the cover portion 32, and the locked portion 42 may be provided on the base portion 31. Furthermore, the locking mechanism 4 may use a mechanism other than the locking portion 41 and the locked portion 42, as long as it can regulate the separation between the base portion 31 and the cover portion 32.

[0028] Similar to the fixing device 1 according to the first embodiment described above, the fixing device 1A according to this embodiment sandwiches the fixed object 90 between the base portion 31 and the cover portion 32, and can appropriately fix the fixed object 90 by the adhesive force of the adhesive portions 312 and 322. Furthermore, the fixing device 1A according to this embodiment has a locking mechanism 4 that restricts the separation of the base portion 31 and the cover portion 32 of the fixing portion 3 from each other, thereby reliably maintaining the fixed state of the base portion 31 and the cover portion 32 relative to the fixed object 90.

[0029] The fixing device according to the present invention is not limited to the above-described embodiments, and various modifications are possible within the scope of the claims. The fixing device according to each embodiment may be configured by appropriately combining the components of the above-described embodiments and modified examples.

[0030] For example, in the above-described embodiments, the fixing devices 1, 1A are 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]
