Description

[Technical Field]

[0001] The present invention relates to a fixing structure for a wire harness that includes a bracket fixed to a fixing 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. [Background technology]

[0002] Conventionally, when wiring a wire harness (i.e., an electrical junction box, a sub-harness, etc.) in an automobile, the electrical junction box may be fixed to the body frame of the automobile, etc. For example, one conventional electrical junction box has a fixing arm portion that extends from the outer wall of the electrical junction box, and this arm portion and the body frame are fastened with bolts (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Publication No. 2022-14260 Summary of the Invention [Problem to be solved by the invention]

[0004] In the conventional electrical junction box described above, a fixing arm portion is provided on the electrical junction box for routing a wire harness (i.e., fixing to a vehicle body). However, since the shape of the vehicle body frame generally varies depending on the type and specifications of the vehicle in which the electrical junction box will be installed, conventional electrical junction boxes have to be prepared in a specific shape for each type and specification of vehicle. From the perspective of further improving the productivity of electrical junction boxes and the ease of routing (fixing) wire harnesses using such electrical junction boxes to vehicles, there is a need for a versatile wire harness fixing structure that allows the same electrical junction box to be used for different types and specifications of vehicles.

[0005] An object of the present invention is to provide a versatile fixing structure for a wire harness. [Means for solving the problem]

[0006] In order to achieve the above-mentioned object, the fixing structure of the wire harness according to the present invention has the following features.

[0007] A fixing structure for a wire harness, comprising: a bracket having a fixing portion to a fixing object; one or more electric junction boxes attached to the bracket; and a sub-harness extending from each of the one or more electric junction boxes, Each of the one or more electrical connection boxes is A locking part with a common shape for attachment to the bracket an insertion portion through which the sub-harness is inserted; and The bracket is a plurality of mounting locations to which the one or more electrical connection boxes can be mounted; and a locked portion provided at each of the plurality of mounting locations and having a shape corresponding to the locking portion; a box-shaped main body portion on which the plurality of attachment points and the locking portion are provided; and a recess portion formed by cutting out a wall portion of the main body portion in a concave shape; and The insertion portion and the recessed portion are forming an annular insertion space through which the sub-harness is inserted; When the fixing structure of the wire harness includes a plurality of the electric connection boxes, The plurality of electrical connection boxes include: The electrical connection box includes an electrical connection box of a predetermined size and an electrical connection box of a size different from the predetermined size. The wire harness must be fixed in place. [Effects of the Invention]

[0008] According to the wire harness fixing structure of the present invention, the bracket has a fixing portion (e.g., a bolt fastening hole) to a fixing object (e.g., a vehicle body frame) and multiple mounting locations for attaching electrical junction boxes. Meanwhile, one or more electrical junction boxes attached to the bracket have a locking portion of a common shape. The multiple mounting locations of the bracket are provided with lockable portions shaped to correspond to the locking portions of the electrical junction boxes. Therefore, for example, by providing a locking portion of a common shape to an electrical junction box of a general-purpose shape (e.g., a simple rectangular parallelepiped shape), it is possible to increase or decrease the number of electrical junction boxes attached to the bracket or change the electronic components stored in the electrical junction box depending on the specifications of the vehicle. In other words, the electrical junction box can be made versatile. Meanwhile, although the bracket has a different shape depending on the specifications of the vehicle, the bracket does not require a structure for storing electronic components inside it like an electrical junction box, so the impact on overall productivity is limited. As such, the wire harness fixing structure of this configuration allows for general-purpose electrical junction boxes while enabling various wire harnesses to be constructed and the wire harnesses to be fixed to a fixing object. Therefore, the fixing structure of the wire harness having this configuration is highly versatile.

[0009] The present invention has been briefly described above. The details of the present invention will become clearer by reading the detailed description of the invention below in conjunction with the accompanying drawings. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

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

[0012] For ease of explanation, the terms "front," "rear," "left," "right," "upper," and "lower" are defined below as shown in FIG. 1 and elsewhere. The front-to-rear, left-to-right, and upper-to-lower directions are perpendicular to one another. In this example, the upper-to-lower direction corresponds to the mounting direction of the electrical junction box 20 to the bracket 10, and the "upper" and "lower" sides correspond to the "upper" and "lower" sides of the automobile when the bracket 10 is fixed to the automobile body frame. However, these directions are defined merely for ease of explanation; the upper-to-lower direction does not necessarily correspond to the mounting direction, and the upper and lower sides do not necessarily correspond to the upper and lower sides of the automobile when the bracket 10 is fixed to the automobile body frame. The configuration of each component used in the fixing structure of the wire harness 1 will be described below.

[0013] First, the electrical junction box 20 will be described. As shown in Figs. 1 and 2, the electrical junction box 20 has a resin housing that is approximately rectangular parallelepiped and extends in the front-rear, left-right, and up-down directions. The housing of the electrical junction box 20 may be formed from a single resin molded body, or may be formed by combining multiple resin molded bodies. The surface of the housing of the electrical junction box 20 does not have any portions for fixing electric wires, connectors, etc. (i.e., auxiliary mounting portions, which will be described later). The electrical junction box 20 is equipped with multiple types of electronic components 21, etc. for controlling the vehicle (see Figs. 1 and 2).

[0014] The front surface (front-facing surface) and rear surface (rear-facing surface) of the electrical junction box 20 are provided with locking portions 22 (see FIGS. 1 and 2) that engage with locked portions 13 (13a, 13b) (see FIG. 3, etc.) of the bracket 10, which will be described later. In this example, the locking portions 22 are composed of a first locking portion 22a provided on the front surface of the electrical junction box 20 and a second locking portion 22b provided on the rear surface of the electrical junction box 20 (see FIG. 2). The structures of the first and second locking portions 22a, 22b are different from each other in this example, but they may be the same.

[0015] An electric wire insertion portion 23 is provided at the lower right end of the front surface of the electric junction box 20 (see FIGS. 1 and 2). From the electric wire insertion portion 23, electric wires 30 (i.e., sub-harness) electrically connected to the electronic components 21 and the like mounted on the electric junction box 20 extend forward from the inside of the electric junction box 20 to the outside (see FIG. 2).

[0016] The housings of one or more electric junction boxes 20 included in the wire harness 1 each have a common, generally rectangular parallelepiped shape. Each of the one or more electric junction boxes 20 included in the wire harness 1 can be attached to either of two attachment locations 12 (12a, 12b) (see FIG. 3) of the bracket 10, which will be described later, but each has different electric circuit specifications.

[0017] Each of the one or more electric junction boxes 20 (electrical junction boxes 20A, 20B) included in the wire harness 1 has a locking portion 22 (first locking portion 22a+second locking portion 22b) of a common shape. Each of the locking portions 22 (first locking portion 22a+second locking portion 22b) of the one or more electric junction boxes 20 included in the wire harness 1 can engage with a locked portion 13 (13a, 13b) provided at either of the two mounting portions 12 (12a, 12b) included in the bracket 10.

[0018] Next, the bracket 10 will be described. The bracket 10 is a resin molded body, and as shown in FIGS. 1 and 3, has a roughly rectangular parallelepiped box-shaped main body 11 that extends in the front-rear, left-right, and up-down directions and is open upward. As shown in FIG. 3, two mounting locations 12 are defined in the roughly rectangular parallelepiped hollow portion of the main body 11 and are aligned adjacent to each other in the left-right direction. Each of the two mounting locations 12 has a common roughly rectangular parallelepiped shape to which an electrical junction box 20 can be attached. Hereinafter, when it is necessary to distinguish between the two mounting locations 12, the left and right mounting locations 12 will be referred to as "mounting location 12a" and "mounting location 12b," respectively.

[0019] Each mounting location 12 is provided with a locked portion 13 corresponding to the locking portion 22 of the electrical connection box 20 (see FIG. 3). In this example, the locked portion 13 is composed of a first locked portion 13a provided on the inner surface (rear-facing surface) of the front wall that defines the main body 11 in correspondence with the first locking 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 11 in correspondence with the second locking portion 22b. Each mounting location 12 has locked portions 13 of a common shape (first locked portion 13a+second locked portion 13b).

[0020] 1, the electric junction box 20 is attached to the attachment location 12 from above. When the electric junction box 20 is attached to the attachment location 12, the locked portion 13 (first locked portion 13a+second locked portion 13b) and the locking portion 22 (first locking portion 22a+second locking portion 22b) engage with each other, thereby preventing the electric junction box 20 from being separated (disconnected) upward from the bracket 10 (main body portion 11).

[0021] At each mounting location 12, a wire insertion recess 14 is provided in a portion of the front wall defining the main body 11, in correspondence with the wire insertion portion 23 of the electric junction box 20, by cutting out a recess facing downward (see FIGS. 1 and 3, etc.). When the electric junction box 20 is mounted at the mounting location 12, the root portions of the electric wires 30 extending forward from the wire insertion portion 23 of the electric junction box 20 are housed in the wire insertion recess 14 (see FIG. 1). The electric wires 30 extending from the wire insertion portion 23 are connected to corresponding electrical equipment (not shown) mounted on the automobile.

[0022] 1 and 3, a plurality of auxiliary mounting points 15 for fastening auxiliary components (such as electric wires and connectors) different from the electrical junction box are provided on the outer surface (the surface facing rearward) of the rear wall that defines the main body 11 of the bracket 10, and on the leg portions 16. Because such auxiliary mounting points 15 are provided on the bracket 10 side, as described above, there is no need for a portion on the electrical junction box 20 side for fastening electric wires, connectors, etc.

[0023] As shown in Figures 1 and 3, etc., legs 16 extend integrally from each of a plurality of locations (two locations in this example) on the outer surface of main body 11 of bracket 10. One or more bolt holes (through holes) 17 are formed at the tip of each leg 16. When bracket 10 is attached to the body frame of an automobile, bolts (not shown) are inserted into these bolt holes 17 to fasten bracket 10 to the body frame of the automobile. The configuration of each component used in the fixing structure of wire harness 1 has been described above.

[0024] As described above, each of the one or more electrical junction boxes 20 included in the wire harness 1 can be attached to either of the two attachment locations 12a, 12b (see FIG. 3 ) of the bracket 10, but has different electrical circuit specifications. Therefore, for example, an electrical junction box 20 can be prepared in advance for each specific system (specification) of the automobile to which the wire harness 1 is applied. That is, each of the one or more electrical junction boxes 20 may store electronic components 21 corresponding to electrical equipment (not shown) that realizes the specific system of the automobile to which the wire harness 1 is applied. In other words, the electric wires 30 extending from each of the one or more electrical junction boxes 20 may be connected to the electrical equipment that realizes the specific system of the automobile to which the wire harness 1 is applied.

[0025] Specifically, for example, assume that a standard electrical junction box 20A corresponding to electrical components related to devices that are installed as standard in an automobile (hereinafter referred to as "standard electrical components") and an optional electrical junction box 20B corresponding to electrical components related to devices that are selectively installed in an automobile (hereinafter referred to as "optional electrical components") are prepared as electrical junction boxes 20 (see FIGS. 4 and 5). Examples of standard electrical components include electrical components used in engine-equipped automobiles, and examples of optional electrical components include electrical components used in hybrid-equipped automobiles.

[0026] In this case, the standard-use electrical junction box 20A is attached to one of the two mounting locations 12a, 12b, and a corresponding option-use electrical junction box 20B is attached to the other of the two mounting locations 12a, 12b depending on the selected optional electrical equipment. In the example shown in FIG. 4, the standard-use electrical junction box 20A is attached to the mounting location 12a, and an option-use electrical junction box 20B corresponding to the selected optional electrical equipment is attached to the mounting location 12b. In the example shown in FIG. 5, the standard-use electrical junction box 20A is attached to the mounting location 12a, but the option-use electrical junction box 20B is not attached because no optional electrical equipment is installed. The electric wires 30 extending from the standard-use electrical junction box 20A are connected to the standard electrical equipment, and the electric wires 30 extending from the option-use electrical junction box 20B are connected to the selected optional electrical equipment.

[0027] In this way, depending on the selected optional electrical equipment, a corresponding optional electrical junction box 20B can be added to the wire harness 1. This eliminates the need for electrical wires and the like (so-called throw-away circuits) that are preliminarily installed in the wire harness 1 regardless of whether or not the optional electrical equipment is installed.

[0028] Furthermore, instead of preparing an electric junction box 20 for each system (specification) of the automobile, an electric junction box 20 can be prepared in advance for each specific area of ​​the automobile to which the wire harness 1 is applied. That is, each of one or more electric junction boxes 20 may store electronic components 21 corresponding to electrical equipment (not shown) installed in the specific area of ​​the automobile to which the wire harness 1 is applied. In other words, the electric wires 30 extending from each of one or more electric junction boxes 20 may be connected to electrical equipment installed in the specific area of ​​the automobile to which the wire harness 1 is applied.

[0029] This allows the electric wires 30 to be separated for each specific area of ​​the automobile. This not only makes it easier to route the electric wires 30, but also improves the maintainability of the wire harness 1 because, if a problem occurs with the electric wire 30 corresponding to a specific area, only that electric wire 30 needs to be repaired or replaced, thereby improving the maintainability of the wire harness 1. Furthermore, as long as the electrical equipment installed in a specific area is the same, the same electric wires 30 can be used even if the automobile model is different, thereby improving the versatility of the wire harness 1.

[0030] <Actions and Effects> As described above, according to the wire harness 1 according to the embodiment of the present invention, the bracket 10 has a fixing portion (e.g., bolt holes 17 for bolt fastening) to a fixing target (e.g., a vehicle body frame) and a plurality of mounting locations 12 for mounting the electrical junction boxes 20. Meanwhile, one or more electrical junction boxes 20 mounted on the bracket 10 have locking portions 22 of a common shape. The plurality of mounting locations 12 of the bracket 10 are provided with lockable portions 13 having shapes corresponding to the locking portions 22 of the electrical junction boxes 20. Therefore, for example, by providing the locking portions 22 of a common shape to electrical junction boxes 20 having a general-purpose shape (e.g., a simple rectangular parallelepiped shape), it is possible to increase or decrease the number of electrical junction boxes 20 mounted on the bracket 10 or to change the electronic components stored in the electrical junction boxes 20 depending on the specifications of the automobile. In other words, the electrical junction boxes 20 can be made versatile. Meanwhile, although the bracket 10 has a different shape depending on the specifications of the automobile, the bracket 10 does not require a structure for storing electronic components therein, as the electrical junction boxes 20 do, and therefore the impact on overall productivity is limited. In this way, the fixing structure of the wire harness 1 of this configuration can configure various wire harnesses 1 and fix the wire harness 1 to a fixing object while generalizing the electric junction box 20. Therefore, the fixing structure of the wire harness 1 of this configuration is excellent in versatility.

[0031] Furthermore, since the main body 11 of the bracket 10 is box-shaped, a mounting 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 an auxiliary mounting point 15 can be provided outside the bracket 10 to secure other electrical wires, connectors, etc.

[0032] <Other forms> It should be noted that the present invention is not limited to the above-described embodiments, and various modifications can be adopted within the scope of the present invention. For example, the present invention is not limited to the above-described embodiments, and modifications, improvements, etc. are possible as appropriate. In addition, the material, shape, dimensions, number, location, etc. of each component in the above-described embodiments are arbitrary and not limited as long as the present invention can be achieved.

[0033] In the above embodiment, the main body 11 of the bracket 10 has a box-like shape with the mounting location 12 inside (hollow portion). In contrast, as shown in Figs. 6 and 7, the main body 11 of the bracket 10 may have a rod-like shape with the mounting location 12 on the outside. In this case, the rod-like main body 11 may be made of metal or resin. In a first modified example shown in Fig. 6, the main body 11 has a rod-like shape that extends linearly in the front-rear direction, and in a second modified example shown in Fig. 7, the main body 11 has a rod-like shape that extends in the front-rear direction while curving in the left-right direction.

[0034] 6 and 7, the leg portions 16 are omitted, and bolt holes 17 are formed at a plurality of positions in the front-rear direction of the rod-shaped main body 11, through which bolts (not shown) are inserted to fasten the bracket 10 to the body frame of the automobile. Mounting positions 12 (12a, 12b, 12c) to which an electric junction box 20 can be mounted are provided at a plurality of positions (three positions) on the left and right side surfaces of the rod-shaped main body 11. Each mounting position 12 (12a, 12b, 12c) is provided with a commonly shaped locked portion 13 corresponding to the commonly shaped locking portion 22 of each of the plurality (three) electric junction boxes 20 (20A, 20B, 20C) of the wire harness 1. An electric wire 40 (different from the electric wire 30 extending from each electrical connection box 20) extending along the rod-shaped main body 11 is fixed to the main body 11 by a predetermined fixing portion (not shown) provided on the main body 11.

[0035] Each of the three electrical junction boxes 20 (20A, 20B, 20C) of the wire harness 1 can be attached to any of the three mounting locations 12 (12a, 12b, 12c) of the bracket 10, but has different electrical circuit specifications. The locking portion 22 of each of the three electrical junction boxes 20 (20A, 20B, 20C) of the wire harness 1 can be engaged with the locked portion 13 provided at any of the three mounting locations 12 (12a, 12b, 12c) of the bracket 10.

[0036] Each electrical junction box 20 is attached to the corresponding attachment location 12 from the side (left or right side). When the electrical junction box 20 is attached to the bracket 10, there are no walls or other components around the electrical junction box 20, which increases the degree of freedom in the shape of the electrical junction box 20.

[0037] 6 and 7, the rod-like shape of the main body 11 of the bracket 10 allows for a simplified shape of the bracket 10 itself. Furthermore, while providing a mounting location 12 for the electrical junction box 20 at a predetermined position on the side of the main body 11 of the bracket 10, an auxiliary mounting location 15 for fixing other electric wires, connectors, etc. can be provided at another position (side surface) of the main body 11 of the bracket 10 (see FIG. 7).

[0038] Furthermore, in the above embodiment, each of the housings of the multiple electrical junction boxes 20 included in the wire harness 1 has a common, approximately rectangular parallelepiped shape of the same size, and correspondingly, each of the multiple mounting locations 12 included in the main body 11 of the bracket 10 has a common, approximately rectangular parallelepiped shape of the same size. In contrast, as in a third modified example shown in Figures 8 and 9, each of the housings of the multiple electrical junction boxes 20 included in the wire harness 1 may have a generally rectangular parallelepiped shape with a size corresponding to the number of electronic components that can be stored, and correspondingly, each of the multiple mounting locations 12 included in the main body 11 of the bracket 10 may have a generally rectangular parallelepiped shape with a size corresponding to the size of the housing of the corresponding electrical junction box 20.

[0039] Specifically, in the example shown in FIGS. 8 and 9 , the wire harness 1 includes a plurality of electrical junction boxes 20, including an electrical junction box 20A capable of storing 10 electronic components, an electrical junction box 20B capable of storing 6 electronic components, and an electrical junction box 20C capable of storing 5 electronic components. The housing of the electrical junction box 20A is larger than the housing of the electrical junction box 20B, and the housing of the electrical junction box 20B is larger than the housing of the electrical junction box 20C. Each of the plurality of electrical junction boxes 20 (20A, 20B, 20C) can configure an electrical circuit with a different specification. The main body 11 of the bracket 10 has two mounting points 12a corresponding to the electrical junction box 20A, two mounting points 12b corresponding to the electrical junction box 20B, and six mounting points 12c corresponding to the electrical junction box 20C. The mounting points 12a are larger than the mounting points 12b, and the mounting points 12b are larger than the mounting points 12c. The two mounting points 12a are arranged adjacent to each other in the left-right direction, the two mounting points 12b are arranged adjacent to the right side of the right mounting point 12a and adjacent to each other in the left-right direction, and the six mounting points 12c are arranged adjacent to the rear sides of the two mounting points 12a and adjacent to each other in the left-right and front-rear directions.

[0040] Each of the multiple electrical junction boxes 20 (20A, 20B, 20C) included in the wire harness 1 has a locking portion 22 of a common shape, and correspondingly, each mounting location 12 (12a, 12b, 12c) is provided with a locked portion 13 of a common shape. The electrical junction box 20A can be attached to either of the two mounting locations 12a, the electrical junction box 20B can be attached to either of the two mounting locations 12b, and the electrical junction box 20C can be attached to any of the six mounting locations 12c. The locking portion 22 of the electrical junction box 20A can engage with the locked portion 13 provided at either of the two mounting locations 12a included in the bracket 10. The locking portion 22 of the electrical junction box 20B can engage with the locked portion 13 provided at either of the two mounting locations 12b included in the bracket 10. The locking portion 22 of the electrical junction box 20C can be engaged with the locked portion 13 provided at any of the six mounting locations 12c that the bracket 10 has.

[0041] In the example shown in Fig. 9, electrical junction boxes 20A are attached to all of the two mounting locations 12a, electrical junction boxes 20B are attached to all of the two mounting locations 12b, and electrical junction boxes 20C are attached to all of the six mounting locations 12c. However, depending on the specifications of the vehicle, electrical junction boxes 20A may be attached to only some of the two mounting locations 12a, or electrical junction boxes 20A may not be attached to any of the two mounting locations 12a. Electrical junction boxes 20B may be attached to only some of the two mounting locations 12b, or electrical junction boxes 20B may not be attached to any of the two mounting locations 12b. Electrical junction boxes 20C may be attached to only some of the six mounting locations 12c, or electrical junction boxes 20C may not be attached to any of the six mounting locations 12c.

[0042] As shown in FIG. 9, a cavity or the like may be provided in a location in the internal space of the bracket 10 other than each mounting location 12 (12a, 12b, 12c) to which various relays, connectors, etc. can be attached.

[0043] 8 and 9, by selecting and using an electric junction box 20 of an appropriate size according to the number of electronic components that can be stored, it is possible to increase or decrease the number of electric junction boxes 20 attached to the bracket 10 and to change the electronic components that can be stored in the electric junction boxes 20 according to the specifications of the automobile, and also to rationally utilize the space inside the bracket 10. This further improves the versatility of the fixing structure of the wire harness 1.

[0044] Here, the features of the embodiments of the fixing structure of the wire harness 1 according to the present invention described above will be briefly summarized and listed below in [1] to [7].

[0045] [1] A fixing structure for a wire harness (1) comprising: a bracket (10) having a fixing portion (17) to a fixing object; one or more electric junction boxes (20) attached to the bracket (10); and a sub-harness (30) extending from each of the one or more electric junction boxes (20), Each of the one or more electrical connection boxes (20) is A locking portion (22) of a common shape for attachment to the bracket (10) is provided. The bracket (10) is a plurality of mounting locations (12) to which the one or more electric connection boxes (20) can be mounted, and a locked portion (13) provided at each of the plurality of mounting locations (12) and having a shape corresponding to the locking portion (22), A fixing structure for a wire harness (1).

[0046] According to the wire harness fixing structure of the above-mentioned configuration [1], the bracket has a fixing portion (e.g., a bolt fastening hole) to a fixing object (e.g., a vehicle body frame) and multiple mounting locations for attaching electrical junction boxes. Meanwhile, one or more electrical junction boxes attached to the bracket have a locking portion of a common shape. The multiple mounting locations of the bracket are provided with lockable portions shaped to correspond to the locking portions of the electrical junction boxes. Therefore, for example, by providing a locking portion of a common shape to an electrical junction box of a general-purpose shape (e.g., a simple rectangular parallelepiped shape), it is possible to increase or decrease the number of electrical junction boxes attached to the bracket or change the electronic components stored in the electrical junction box depending on the specifications of the vehicle. In other words, the electrical junction box can be made versatile. Meanwhile, although the bracket has a different shape depending on the specifications of the vehicle, the bracket does not require a structure for storing electronic components inside it like an electrical junction box, so the impact on overall productivity is limited. Thus, the wire harness fixing structure of this configuration makes it possible to construct a wide variety of wire harnesses and fix the wire harnesses to a fixing object while making the electrical junction box versatile. Therefore, the fixing structure of the wire harness having this configuration is highly versatile.
