[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. 1 is a perspective view of the fixing device 1 with the fixing portion 3 in a provisionally locked state, and Fig. 2 is a rear view of the fixing device 1 with the fixing portion 3 in an open state.

[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, and is made of 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 part to be fixed 91. The part to be fixed 91 is a plate-like portion formed on the object to be fixed 90, and is formed, for example, so as to protrude from a surface 90A of the object to be fixed 90. The part to be fixed 91 is formed as a plate without any holes for fastening.

[0014] The fixing device 1 includes a wire attachment portion 2, a fixing portion 3, and a locking mechanism 4. The 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 a free end that can be engaged with the joint portion 21. The bundling portion 22 can be wound around the electric wire 10 and the tip end engaged with the joint portion 21, thereby attaching the fixing device 1 to the electric wire 10. Note that the 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 part to be fixed 90, and is provided integrally with the electric wire attachment part 2. The fixing part 3 has a base part 31 and a cover part 32, and sandwiches and holds the part to be fixed 91 between the base part 31 and the cover part 32 to fix the part to the part to be fixed 90. The base part 31 is joined to the joint part 21 of the electric wire attachment part 2. The base part 31 and the cover part 32 are formed in a plate shape, and sandwich and fix the part to be fixed 91. The cover part 32 is a movable part that is provided so as to be rotatable so as to move towards and away from the base part 31, and sandwiches the part to be fixed 91 between itself and the base part 31 when it is close to the base part 31.

[0016] The fixed part 3 is provided with a hinge part 33. The hinge part 33 is a part that rotatably supports the cover part 32 with respect to the base part 31, and is provided by connecting an end part of the base part 31 and an end part of the cover part 32. The hinge part 33, for example, connects an end part of the base part 31 in the extension direction Y and an end part of the cover part 32 in the extension direction Y, and supports the cover part 32 rotatably about an axis along the connection direction X. The main body part 311 of the base part 31, the main body part 321 of the cover part 32, and the hinge part 33 are made of resin and are integrally formed, for example, by resin molding.

[0017] The base portion 31 has a main body portion 311 and an elastic portion 312. The main body portion 311 is provided as a plate and is joined to the hinge portion 33. The elastic portion 312 is provided inside the main body portion 311 at a position where it contacts the fixed portion 91. The elastic portion 312 is formed of an elastically deformable material, such as rubber or foam, that has a larger coefficient of friction than the main body portion 311. The elastic portion 312 may be provided by being attached to the main body portion 311 as a separate member, or may be provided by being molded integrally with the main body portion 311 by two-color molding or the like. By providing the elastic portion 312 on the base portion 31, it is possible to firmly hold the fixed portion 91.

[0018] The cover part 32 has a main body part 321 and an elastic part 322. The main body part 321 is provided as a plate body and is joined to the hinge part 33. The elastic part 322 is provided inside the main body part 321 at a position where it contacts the fixed part 91. The elastic part 322 is formed of an elastically deformable material, such as rubber or foam, that has a larger coefficient of friction than the main body part 321. The elastic part 322 may be provided by being attached to the main body part 321 as a separate member, or may be provided by being molded integrally with the main body part 321 by two-color molding or the like. By providing the elastic part 322 on the cover part 32, it is possible to firmly hold the fixed part 91.

[0019] The locking mechanism 4 is a mechanism for engaging the base portion 31 with the cover portion 32, and for example, engages the base portion 31 with the cover portion 32 in a state in which the cover portion 32 is close to the base portion 31. The locking mechanism 4 has an engaged portion 41 and an engaging portion 42. The engaged portion 41 is provided on the base portion 31. For example, the engaged portion 41 is provided on an end portion of the main body portion 311 of the base portion 31 in the extension direction Y, on the opposite end portion to where it is joined to the hinge portion 33. The engaged portion 41 has an engaging hole 411 for inserting the engaging portion 42. The engaging hole 411 is formed so as to pass through the engaged portion 41 along the height direction Z, for example.

[0020] The locking portion 42 is provided on the cover portion 32. For example, the locking portion 42 is provided at an end of the main body portion 321 of the cover portion 32 in the extension direction Y, on the opposite end to where the hinge portion 33 is joined. The locking portion 42 is formed as a rod-like or plate-like body extending from the end of the main body portion 321 of the cover portion 32 in the rotation direction. The locking portion 42 has a temporary locking projection 421 and a full locking projection 422. The temporary locking projection 421 and the full locking projection 422 are projections that protrude from the side surface of the locking portion 42 and are formed in a lance shape that tapers toward the tip side of the locking portion 42. The temporary locking projection 421 is formed closer to the tip side of the locking portion 42 than the full locking projection 422. Therefore, when the locking portion 42 is inserted into the locking hole 411 , the temporary locking projection 421 is inserted into the locking hole 411 before the full locking projection 422 .

[0021] The locking mechanism 4 rotates the cover part 32 so as to approach the base part 31, and engages the locking part 42 with the locked part 41 to restrict the rotation of the cover part 32. The locking mechanism 4 can lock the cover part 32 at a full locking position where the fixed part 91 is sandwiched between the base part 31 and the cover part 32, and at a temporary locking position where the cover part 32 is spaced apart from the base part 31 compared to the full locking position. For example, the locking mechanism 4 can lock the cover part 32 to the base part 31 at the temporary locking position by inserting the temporary locking projections 421 of the locking parts 42 into the locking holes 411 to lock them. The locking mechanism 4 can also lock the cover part 32 to the base part 31 at the full locking position by inserting the full locking projections 422 of the locking parts 42 into the locking holes 411 to lock them.

[0022] Next, the fixing of the fixing device 1 according to this embodiment to the fixed object 90 will be described.

[0023] First, 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.

[0024] Then, as shown in FIG. 4A , the fixing part 3 is brought into a provisionally locked state by the locking mechanism 4. That is, as shown in FIG. 2 , the cover part 32 is rotated about the hinge part 33 and rotated so as to approach the base part 31. Then, as shown in FIG. 3 , the locking part 42 is engaged with the locked part 41, and the locking mechanism 4 is brought into a provisionally locked state. Specifically, the locking part 42 is inserted into the locking hole 411 of the locked part 41, the provisionally locked protrusion 421 is inserted into the locking hole 411, and the provisionally locked protrusion 421 is engaged with the locked part 41, thereby bringing the fixing part 3 into a provisionally locked state. By bringing the fixing part 3 into a provisionally locked state, a large space is formed between the base part 31 and the cover part 32 for inserting the fixed part 91 therethrough. This allows the fixed part 91 to be smoothly inserted between the base part 31 and the cover part 32.

[0025] 1, the fixing part 3 is disposed so as to face the fixed part 91, and is moved so that the fixed part 91 is inserted between the base part 31 and the cover part 32. At this time, the base part 31 and the cover part 32 are locked in the provisional locking position by the locking mechanism 4, so that the fixed part 91 can be smoothly inserted between the base part 31 and the cover part 32.

[0026] Then, the fixed portion 91 is sandwiched between the base portion 31 and the cover portion 32, and the fixed portion 91 is held by the base portion 31 and the cover portion 32. At this time, because the base portion 31 and the cover portion 32 sandwich the fixed portion 91 from the temporary locking position, the fixed portion 91 can be held by the base portion 31 and the cover portion 32 without rotating the cover portion 32 significantly. For example, as shown in FIG. 4B , by pressing the base portion 31 and the cover portion 32 toward each other, the temporary locking state changes to the final locking state, and the fixed portion 91 is held. That is, by pressing the base portion 31 and the cover portion 32 toward each other, the final locking protrusions 422 are inserted into the locking holes 411 and are locked to the locked portion 41, thereby achieving the final locking state. The base part 31 and the cover part 32 can be moved from the provisionally locked position (provisionally locked state) to the fully locked position (fully locked state) with one hand, so the fixing operation can be performed easily and smoothly.

[0027] 4(C), when the base portion 31 and the cover portion 32 are in a fully locked state, the fixed portion 91 is firmly held by the base portion 31 and the cover portion 32, completing the fixing of the fixing device 1. At this time, the elastic portions 312 and 322 contact and hold the fixed portion 91, so that even if the fixed portion 91 is tightly clamped, the fixed portion 91 is prevented from being damaged. Furthermore, because the coefficient of friction of the elastic portions 312 and 322 is greater than that of the main body portions 311 and 321, the fixed portion 91 is prevented from slipping out from between the base portion 31 and the cover portion 32, and can be properly fixed to the fixed portion 91.

[0028] As described above, the fixing device 1 according to this embodiment can be properly fixed to the object 90 by clamping the fixed part 91 with the fixing part 3 to fix it, even if no fixing hole is formed in the fixed part 91. Furthermore, the fixing device 1 according to this embodiment can be smoothly fixed to the object 90 by allowing the locking mechanism 4 to lock the base part 31 and the cover part 32 in the provisional locking position.

[0029] Furthermore, in the fixing device 1 according to this embodiment, the base portion 31 and the cover portion 32 have the elastic portion 312 and the elastic portion 322, so that the fixed portion 91 can be properly sandwiched and held by the base portion 31 and the cover portion 32.

[0030] 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.

[0031] 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]
