Summary of the Invention

Problems to be Solved by the Invention

[0004] In the above-described conventional electrical connection box, a fixing arm portion is provided in the electrical connection box for wiring the wire harness (i.e., fixing to the vehicle body). However, in general, since the shape of the vehicle body frame and the like differ depending on the type and specifications of the automobile on which the electrical connection box is to be mounted, in the conventional electrical connection box, a dedicated-shaped electrical connection box needs to be prepared for each type and specification of the automobile. From the viewpoint of further improving the productivity of the electrical connection box and the workability when wiring (fixing) the wire harness using the electrical connection box to the automobile, a fixing structure for a wire harness with excellent versatility is desired so that the electrical connection box can be shared even if the types and specifications of the automobiles are different.

[0005] One of the objectives of the present invention is to provide a wire harness fixing structure with excellent versatility. [Means for solving the problem]

[0006] To achieve the aforementioned objectives, the wire harness fixing structure according to the present invention is characterized by the following:

[0007] A wire harness fixing structure comprising: a bracket having a fixing portion to a fixed object; one or more electrical junction boxes attached to the bracket; and sub-harnesses extending from each of the one or more electrical junction boxes, Each of the one or more electrical connection boxes is: It has a locking mechanism of a common shape for attachment to the bracket, The aforementioned bracket is A plurality of mounting locations to which one or more of the aforementioned electrical connection boxes can be attached, and a locking mechanism provided at each of the plurality of aforementioned mounting locations having a shape corresponding to the locking mechanism, The locking mechanism and the locked mechanism are, The locking mechanism is configured to engage a first locking portion of the locked mechanism with a first locked portion of the locked mechanism, and while rotating the electrical connection box around the engagement point between the first locking portion and the first locked portion, the locking mechanism is configured to engage a second locking portion of the locked mechanism with a second locked portion of the locked mechanism. The wire harness must have a secure fixing structure. [Effects of the Invention]

[0008] According to the wire harness fixing structure of the present invention, the bracket has fixing points (e.g., holes for bolt fastening) to the object to be fixed (e.g., vehicle frame) and multiple mounting points for attaching an electrical junction box. On the other hand, one or more electrical junction boxes attached to the bracket have a locking mechanism of a common shape. The multiple mounting points of the bracket are provided with locking mechanisms of a shape corresponding to the locking mechanism of the electrical junction box. When attaching an electrical junction box to the bracket, the first locking part of the electrical junction box is engaged with the first locking part of the bracket, and while rotating the electrical junction box around the engagement point, the second locking part of the electrical junction box is engaged with the second locking part of the bracket. Therefore, for example, a common locking mechanism can be provided for an electrical junction box with a general-purpose shape (e.g., a simple rectangular parallelepiped shape), and the number of electrical junction boxes attached to the bracket can be increased or decreased, or the electronic components stored in the electrical junction box can be replaced, depending on the specifications of the automobile. In other words, the electrical junction box can be made general-purpose. On the other hand, although the bracket will have a different shape depending on the specifications of the automobile, the bracket does not require a structure that houses electronic components inside, like an electrical junction box, so the impact on overall productivity is limited. Furthermore, the engagement point that serves as the pivot point when attaching the electrical junction box to the bracket while rotating it does not require a complex shape such as a spring structure like a typical locking claw. Therefore, the structure of the locking mechanism and the locked mechanism can be simplified, improving the productivity of the electrical junction box and bracket. In this way, the wire harness fixing structure of this configuration allows for the generalization of the electrical junction box, the configuration of various wire harnesses, and the fixing of the wire harness to the target object.

[0009] The present invention has been briefly described above. Furthermore, the details of the present invention will be further clarified by referring to the attached drawings and reading through the embodiments for carrying out the invention described below (hereinafter referred to as "embodiments"). [Brief explanation of the drawing]

[0010] [Figure 1] Figure 1 is a perspective view illustrating a wire harness fixing structure according to an embodiment of the present invention. [Figure 2] Figure 2 is a view of the wire harness fixing structure shown in Figure 1, from the right side, with the right leg portion omitted from the illustration. [Figure 3] Figure 3 is a top view of the electrical junction box shown in Figure 1. [Figure 4] Figure 4 is a top view of the bracket shown in Figure 1. [Figure 5] Figure 5 is a top view showing the bracket with electrical junction boxes attached to each of its two mounting points. [Figure 6] Figure 6 is a top view showing a state in which an electrical junction box is attached to only one of the two mounting points on the bracket. [Modes for carrying out the invention]

[0011] <Embodiment> The fixing structure of the wire harness 1 according to an embodiment of the present invention will be described below with reference to the drawings. The wire harness 1 used in this fixing structure comprises one or more electrical connection boxes 20 attached to a bracket 10, and electric wires 30 extending from each of the one or more electrical connection boxes 20, as shown in Figure 1. This wire harness 1 is fixed to an object to be fixed, such as a vehicle body frame of an automobile, via the bracket 10. Note that the wire harness 1 may be considered to include the bracket 10, the electrical connection boxes 20, and the electric wires 30.

[0012] For the sake of clarity, the terms "front," "rear," "left," "right," "up," and "down" are defined below, as shown in Figure 1, etc. The front-rear, left-right, and up-down directions are orthogonal to each other. The up-down direction coincides with the mounting direction of the electrical junction box 20 to the bracket 10, and the "up" side and "down" side coincide with the "up" side and "down" side of the automobile when the bracket 10 is fixed to the automobile's body frame, respectively. The configuration of each component used in the fixing structure of the wire harness 1 will be described in order below.

[0013] First, the electrical connection box 20 will be described. As shown in FIGS. 1 to 3, the electrical connection box 20 has a substantially rectangular parallelepiped resin housing that extends in the front-rear direction, left-right direction, and up-down direction. The housing of the electrical connection box 20 may be composed of a single resin molded body or may be composed of a combination of a plurality of resin molded bodies. On the surface of the housing of the electrical connection box 20, there is no portion (i.e., an auxiliary attachment location described later) for fixing electric wires, connectors, etc. A plurality of types of electronic components 21 for controlling the vehicle are mounted on the electrical connection box 20 (see FIGS. 1 to 3).

[0014] On the front surface (the front-facing surface) and the rear surface (the rear-facing surface) of the electrical connection box 20, a locking mechanism 22 that engages with a later-described locked mechanism 13 (the first locked portion 13a + the second locked portion 13b. See FIGS. 4 etc.) of the bracket 10 is provided (see FIGS. 1 to 3). In this example, the locking mechanism 22 is composed of a first locking portion 22a provided on the front surface of the electrical connection box 20 and a second locking portion 22b provided on the rear surface of the electrical connection box 20 (see FIGS. 2 and 3). The structures of the first and second locking portions 22a, 22b are different from each other as will be described later.

[0015] An electric wire insertion portion 23 is provided at the lower right end of the front surface of the electrical connection box 20 (see FIGS. 1 and 3). From the electric wire insertion portion 23, an electric wire 30 (i.e., a sub-harness) electrically connected to the electronic components 21 etc. mounted on the electrical connection box 20 extends forward from the inside of the electrical connection box 20 to the outside (see FIG. 3).

[0016] Each of the housings of one or more electrical connection boxes 20 included in the wire harness 1 has a substantially rectangular parallelepiped common shape. Each of the one or more electrical connection boxes 20 included in the wire harness 1 can be attached to any of the two attachment locations 12 (12a, 12b) (see FIG. 4) that the bracket 10 has, while having different electrical circuit specifications from each other.

[0017] Each of the one or more electrical connection boxes 20 (electrical connection boxes 20A and 20B) of the wire harness 1 has a lock mechanism 22 of a common shape (first lock portion 22a + second lock portion 22b). The lock mechanism 22 (first lock portion 22a + second lock portion 22b) of each of the one or more electrical connection boxes 20 of the wire harness 1 can engage with the locked mechanism 13 (first locked portion 13a + second locked portion 13b) provided at any of the two attachment locations 12 (12a, 12b) of the bracket 10.

[0018] Next, the bracket 10 will be described. The bracket 10 is a resin molded body and has a substantially rectangular parallelepiped box-shaped main body portion 11 that extends in the front-rear direction, left-right direction, and up-down direction and opens upward as shown in FIGS. 1 and 4. In the substantially rectangular parallelepiped hollow portion of the main body portion 11, two attachment locations 12 arranged adjacent to each other in the left-right direction are defined as shown in FIG. 4. Each of the two attachment locations 12 has a substantially rectangular parallelepiped common shape to which the electrical connection box 20 can be attached. Hereinafter, when it is necessary to distinguish between the two attachment locations 12, the left and right attachment locations 12 are referred to as "attachment location 12a" and "attachment location 12b", respectively.

[0019] At each attachment location 12, a locked mechanism 13 is provided corresponding to the lock mechanism 22 of the electrical connection box 20 (see FIG. 4). In this example, the locked mechanism 13 includes a first locked portion 13a provided on the inner surface (rear-facing surface) of the front wall that defines the main body portion 11 corresponding to the first lock portion 22a, and a second locked portion 13b provided on the inner surface (front-facing surface) of the rear wall that defines the main body portion 11 corresponding to the second lock portion 22b. Each attachment location 12 has a locked mechanism 13 of a common shape (first locked portion 13a + second locked portion 13b).

[0020] The electrical junction box 20 is installed at the mounting location 12 by the following procedure. First, as shown in Figures 1 and 2, the electrical junction box 20 is tilted from a horizontal position so that its rear side is lower than its front side, and the second locking part 22b is engaged with the second locked part 13b. The dashed line in Figure 2 shows the position of the electrical junction box 20 when the second locking part 22b and the second locked part 13b are engaged and the electrical junction box 20 is tilted in this manner. Next, while rotating the electrical junction box 20 around the engagement points of the second locking part 22b and the second locked part 13b in a direction that returns it to a horizontal position (see the white arrows in Figures 1 and 2), the first locking part 22a is engaged with the first locked part 13a. This completes the installation of the electrical junction box 20 at the mounting location 12. When the electrical junction box 20 is attached to the mounting location 12, the locking mechanism 13 (first locking part 13a + second locking part 13b) and the locking mechanism 22 (first locking part 22a + second locking part 22b) engage with each other, preventing the electrical junction box 20 from separating (coming out) upward from the bracket 10 (main body part 11).

[0021] The second locking portion 22b and the second locked portion 13b may have any structure, as long as the second locking portion 22b is able to engage with the second locked portion 13b so that the second locking portion 22b is supported by the second locked portion 13b so that it can rotate around the second locked portion 13b, and the second locking portion 22b engaged with the second locked portion 13b is prevented from separating upward from the second locked portion 13b in the horizontal position of the electrical junction box 20. The first locking portion 22a and the first locked portion 13a may have any structure, as long as the first locking portion 22a is able to engage with the first locked portion 13a as the rotation of the electrical junction box 20 progresses in the direction of returning to the horizontal position, and the first locking portion 22a engaged with the first locked portion 13a is prevented from separating upward from the first locked portion 13a in the horizontal position of the electrical junction box 20.

[0022] Each mounting location 12 is provided with a wire insertion recess 14, which is cut out in a downward-facing concave shape (extending downward along the rotational direction of the electrical connection box 20) in a part of the front wall defining the main body 11, corresponding to the wire insertion section 23 of the electrical connection box 20 (see Figures 1 and 4, etc.). When the electrical connection box 20 is mounted on the mounting location 12, the base of the wire 30 extending forward from the wire insertion section 23 of the electrical connection box 20 is housed in the wire insertion recess 14 (see Figure 1). The wire 30 extending from the wire insertion section 23 is connected to the corresponding electrical component (not shown) installed in the automobile.

[0023] As shown in Figures 1, 2, and 4, the outer surface (rear-facing surface) of the rear wall defining the main body 11 of the bracket 10 and the leg portion 16 are provided with multiple auxiliary mounting points 15 for fixing auxiliary components other than the electrical junction box (for example, electric wires and connectors). Since these auxiliary mounting points 15 are provided on the bracket 10 side, as described above, there is no need for parts on the electrical junction box 20 side to fix electric wires, connectors, etc.

[0024] As shown in Figures 1 and 4, legs 16 extend integrally from multiple locations (two locations in this example) on the outer surface of the main body 11 of the bracket 10. One or more bolt holes (through holes) 17 are formed at the tip of each leg 16. The legs 16 (i.e., the bolt holes 17) are positioned so as not to interfere with the electric wires 30 extending from the electrical connection box 20 attached to the bracket 10 (see Figure 1). When the bracket 10 is attached to the vehicle frame, bolts (not shown) inserted through these bolt holes 17 are used to fasten and fix the bracket 10 to the vehicle frame. The configuration of each component used in the fixing structure of the wire harness 1 has been described above.

[0025] As described above, each of the one or more electrical junction boxes 20 of the wire harness 1 can be attached to either of the two mounting locations 12a, 12b (see Figure 4) of the bracket 10, while having different electrical circuit specifications. Therefore, for example, an electrical junction box 20 can be prepared in advance for each specific system (specification) of the vehicle to which the wire harness 1 is applied. That is, each of the one or more electrical junction boxes 20 may contain electronic components 21 corresponding to electrical components (not shown) that realize a specific system of the vehicle to which the wire harness 1 is applied. In other words, the wires 30 extending from each of the one or more electrical junction boxes 20 may be connected to electrical components that realize a specific system of the vehicle to which the wire harness 1 is applied.

[0026] Specifically, consider a case where, for example, two electrical junction boxes 20 are prepared: a standard electrical junction box 20A corresponding to electrical components related to equipment that is standard equipment on the vehicle (hereinafter referred to as "standard electrical components"), and an optional electrical junction box 20B corresponding to electrical components related to equipment that is selectively equipped on the vehicle (hereinafter referred to as "optional electrical components") (see Figures 5 and 6). Examples of standard electrical components include electrical components used in engine-powered vehicles, and examples of optional electrical components include electrical components used in hybrid vehicles.

[0027] In this case, the standard electrical junction box 20A is installed at one of the two mounting locations 12a and 12b, and the corresponding optional electrical junction box 20B is installed at the other mounting location 12a and 12b, depending on the selected optional electrical component. In the example shown in Figure 5, the standard electrical junction box 20A is installed at mounting location 12a, and the optional electrical junction box 20B corresponding to the selected optional electrical component is installed at mounting location 12b. In the example shown in Figure 6, the standard electrical junction box 20A is installed at mounting location 12a, while the optional electrical junction box 20B is not installed because no optional electrical component is installed. The wire 30 extending from the standard electrical junction box 20A is connected to the standard electrical component, and the wire 30 extending from the optional electrical junction box 20B is connected to the selected optional electrical component.

[0028] Thus, depending on the selected optional electrical component, the corresponding optional electrical connection box 20B should be added to the wire harness 1. This eliminates the need for spare wires (so-called disposable circuits) that are installed on the wire harness 1 regardless of whether or not optional electrical components are installed.

[0029] Alternatively, instead of preparing an electrical junction box 20 for each vehicle system (specification), the electrical junction boxes 20 can be prepared in advance for each specific area of ​​the vehicle to which the wire harness 1 is applied. That is, each of the one or more electrical junction boxes 20 may contain electronic components 21 corresponding to electrical equipment (not shown) installed in a specific area of ​​the vehicle to which the wire harness 1 is applied. In other words, the wires 30 extending from each of the one or more electrical junction boxes 20 may be connected to electrical equipment installed in a specific area of ​​the vehicle to which the wire harness 1 is applied.

[0030] This allows for the independent routing of the wires 30 to specific areas of the vehicle. This simplifies the wiring work of the wires 30, and if a problem occurs with the wires 30 corresponding to a specific area, only that wire 30 needs to be repaired or replaced, thus improving the maintainability of the wire harness 1. Furthermore, if the electrical components installed in a specific area are the same, the same wires 30 can be used even if the vehicle model differs, thus increasing the versatility of the wire harness 1.

[0031] <Effects and Actions> As described above, according to the fixing structure of the wire harness 1 according to the embodiment of the present invention, the bracket 10 has fixing parts (for example, bolt holes 17 for bolt fastening) to the object to be fixed (for example, the vehicle frame) and a plurality of mounting locations 12 for attaching the electrical connection box 20. On the other hand, one or more electrical connection boxes 20 attached to the bracket 10 have a locking mechanism 22 of a common shape. The plurality of mounting locations 12 of the bracket 10 are provided with a locking mechanism 13 that corresponds to the shape of the locking mechanism 22 of the electrical connection box 20. When attaching the electrical connection box 20 to the bracket 10, the second locking part 22b of the electrical connection box 20 is engaged with the second locking part 13b of the bracket 10, and while rotating the electrical connection box 20 around the engagement location, the first locking part 22a of the electrical connection box 20 is engaged with the first locking part 13a of the bracket 10. Therefore, for example, a locking mechanism 22 of a common shape can be provided on an electrical junction box 20 with a general-purpose shape (for example, a simple rectangular parallelepiped shape), and the number of electrical junction boxes 20 attached to the bracket 10 can be increased or decreased, or the electronic components 21 stored in the electrical junction box 20 can be replaced, depending on the specifications of the automobile. In other words, the electrical junction box 20 can be made general-purpose. On the other hand, although the bracket 10 will have different shapes depending on the specifications of the automobile, the bracket 10 does not require a structure that stores electronic components 21 inside like the electrical junction box 20, so the impact on overall productivity is limited. Furthermore, the engagement point that serves as the pivot point when attaching the electrical junction box 20 to the bracket 10 while rotating it does not require a complex shape such as a locking claw with a general spring structure. Therefore, the structure of the locking mechanism 22 and the locking mechanism 13 can be simplified, and the productivity of the electrical junction box 20 and the bracket 10 can be improved. In this way, the fixing structure of the wire harness 1 according to this embodiment makes the electrical junction box 20 general-purpose, while configuring various types of wire harnesses 1 and fixing the wire harness 1 to the object to be fixed.

[0032] Furthermore, the front wall of the bracket 10 has a wire insertion recess 14 that extends vertically along the rotational direction of the electrical junction box 20 when it is attached to the mounting location (see the arrows in Figures 1 and 2), corresponding to the wire 30. As a result, when the electrical junction box 20 is attached to the bracket 10 while rotating it, the wire 30 will naturally fit into the wire insertion recess 14 of the bracket 10. Therefore, the work of pulling the wire 30 out of the bracket 10 becomes easier, improving the work efficiency of attaching the electrical junction box 20 to the bracket 10.

[0033] Furthermore, the bracket 10 has legs 16 positioned so as not to interfere with the electric wires 30. This makes it less likely for the electric wires 30 to obstruct the work of routing the wire harness 1 with the electrical connection box 20 attached to the bracket 10 (i.e., the work of fixing the bracket 10 to the vehicle frame, etc.). Thus, the work efficiency of routing the wire harness 1 is improved.

[0034] Furthermore, because the main body 11 of the bracket 10 is box-shaped, an attachment point 12 for the electrical connection box 20 can be provided inside the bracket 10 (main body 11) to protect the electrical connection box 20, while auxiliary attachment points 15 for fixing other wires, connectors, etc. can be provided on the outside of the bracket 10.

[0035] <Other forms> It should be noted that the present invention is not limited to the embodiments described above, and various modifications can be adopted within the scope of the present invention. For example, the present invention is not limited to the embodiments described above, and can be modified, improved, etc. as appropriate. Furthermore, the material, shape, dimensions, number, placement, etc. of each component in the embodiments described above are arbitrary and not limited as long as they can achieve the present invention.

[0036] Here, the features of the embodiments of the fixing structure of the wire harness 1 according to the present invention described above are briefly summarized and listed below in [1] to [3].

On the other hand, one or more electrical junction boxes attached to the bracket have a locking mechanism of a common shape. The multiple mounting points of the bracket are provided with locking mechanisms of a shape corresponding to the locking mechanism of the electrical junction box. When attaching an electrical junction box to the bracket, the first locking part of the electrical junction box is engaged with the first locking part of the bracket, and while rotating the electrical junction box around the engagement point, the second locking part of the electrical junction box is engaged with the second locking part of the bracket. Therefore, for example, a common locking mechanism can be provided for an electrical junction box of a general-purpose shape (e.g., a simple rectangular parallelepiped shape), and the number of electrical junction boxes attached to the bracket can be increased or decreased, or the electronic components stored in the electrical junction box can be replaced, depending on the specifications of the automobile. In other words, the electrical junction box can be made general-purpose. On the other hand, although the bracket will have a different shape depending on the specifications of the automobile, the bracket does not require a structure that houses electronic components inside, like an electrical junction box, so the impact on overall productivity is limited. Furthermore, the engagement point that serves as the pivot point when attaching the electrical junction box to the bracket while rotating it does not require a complex shape such as a spring structure like a typical locking claw. Therefore, the structure of the locking mechanism and the locked mechanism can be simplified, improving the productivity of the electrical junction box and bracket. In this way, the wire harness fixing structure of this configuration allows for the generalization of the electrical junction box, the configuration of various wire harnesses, and the fixing of the wire harness to the target object.

Fixing structure for wire harness (1).

[0040] According to the wire harness fixing structure of the configuration described in [2] above, the outer wall of the bracket has a notch that extends along the direction of rotation of the electrical junction box when the electrical junction box is attached to the mounting location, at a location corresponding to the sub-harness. As a result, when the electrical junction box is attached to the bracket while rotating it, the sub-harness will naturally fit into the notch of the bracket. Therefore, the work of pulling the sub-harness out of the bracket becomes easier, and the work efficiency of attaching the electrical junction box to the bracket is improved.

As a result, the sub-harness is less likely to interfere with the work of routing the wire harness with the electrical junction box attached to the bracket (i.e., the work of fixing the bracket to the vehicle frame, etc.). Therefore, the workability of routing the wire harness is improved. [Explanation of Symbols]
