FIG. 8 is a left side view of the electrical component arrangement structure 1, and FIG. 9 is a perspective view of the electrical component arrangement structure 1 viewed diagonally from the upper left.

Mainly referring to FIGS. 3 to 5, the electrical component layout structure 1 includes a fuse insertion portion 3 into which a fuse 2A is inserted, a fuse holding portion 4 in which a fuse 2B is held, and a coupler insertion portion in which a coupler 5 is held. 6, and a fuse box 8. When viewed in direction d1, the fuse box 8 is arranged behind the front battery 120, and behind the fuse box 8, the fuse inserting portion 3, the fuse holding portion 4, and the coupler inserting portion 6 are arranged. The fuse inserting portion 3, the fuse holding portion 4, and the coupler inserting portion 6 are arranged in a line in the d2 direction, and the order of arrangement is the fuse inserting portion 3, the coupler inserting portion 6, and the fuse holding portion 4 from the right. Therefore, the coupler inserting portion 6 is arranged between the fuse inserting portion 3 and the fuse holding portion 4 in the d2 direction.

The fuse box 8 has a plurality of fuse insertion portions 8a arranged in the d2 direction. A fuse different from the fuses 2A and 2B (blade-type fuse not shown in the present embodiment) is inserted in each fuse insertion portion 8a in the d3 direction. Each fuse insertion portion 8a is provided with a pair of electrical connection terminals connected via a blade type fuse. A lid (not shown) is attached to the fuse box 8 to cover the fuse insertion portion 8a.

The fuse insertion portion 3 has a rectangular tubular shape with an open top, and a cable C1 is connected to the bottom portion thereof. A pair of electrical connection terminals 3a (one of the electrical connection terminals 3a is indicated by a dashed line in FIG. 4) is provided in the fuse insertion portion 3 for connecting the wires in the cable C1. The fuse 2A is inserted into the fuse insertion portion 3 in the insertion direction Id1, and electrically connects a pair of electrical connection terminals 3a in the fuse insertion portion 3. As shown in FIG. In this embodiment, the insertion direction Id1 is the d3 direction. The fuse insert 3 is fixed to the wall of the fuse box 8 .

FIG. 10 shows two perspective views of the fuse 2A from different viewpoints. The fuse 2A is a slow-blow fuse in this embodiment, and is a block member having a rectangular parallelepiped shape as a whole. Specifically, fuse 2A includes head 20 and body 21 . The head portion 20 has a rectangular plate shape, and the body portion 21 has a quadrangular prism shape slightly smaller than the head portion 20 . A bottom surface 21a of the body portion 21 is provided with a pair of insertion openings 22 to which a pair of electrical connection terminals 3a are connected. The fuse 2A has the L1 direction as its longitudinal direction (full length direction) and the L2 direction and the L3 direction as its lateral direction (width direction). The lengths of the fuse 2A in the longitudinal and lateral directions satisfy the relationship of length L1>length L2>length L3.

The fuse 2A is removably inserted into the fuse insertion portion 3 with the L1 direction as the insertion direction. As shown in FIGS. 4 and 5, when the fuse 2A is inserted into the fuse insertion portion 3, most of the body portion 21 of the fuse 2A is fitted into the fuse insertion portion 3, and the head portion 20 is fitted into the fuse insertion portion 3. exposed to the outside. Since the head portion 20 protrudes in the L2 and L3 directions with respect to the body portion 21, the operator can easily pull out the fuse 2A from the fuse insertion portion 3 upward by hooking the finger on the head portion 20. . When the fuse 2A is inserted into the fuse insertion portion 3 and in its use state, the longitudinal direction L1 of the fuse 2A is oriented in the d3 direction, the lateral direction L2 is oriented in the d1 direction, and the lateral direction L3 is oriented in the d2 direction. are doing.

The fuse holding portion 4 is a member for holding the fuse 2B. Fuse 2B is a spare fuse for fuse 2A and is the same fuse as fuse 2A. The fuse 2B is inserted and held in the fuse holding portion 4 in the insertion direction Id3. In this embodiment, the insertion direction Id3 is the d3 direction. As will be described later, the fuse 2B is held in the fuse holding portion 4 in a posture different from that of the fuse 2A inserted in the fuse insertion portion 3 .

The coupler 5 is provided at one end of the cable C2, and the other end of the cable C2 is connected to a control unit (not shown) of the vehicle 100. As shown in FIG. Coupler 5 is connected to a dedicated tool when diagnosing vehicle 100 or the like, and cable C2 has a communication line between the dedicated tool and the control unit of vehicle 100 . Therefore, coupler 5 and cable C2 are not used when vehicle 100 is in use. The coupler inserting portion 6 is a member for holding the coupler 5 in one place so that the coupler 5 and the cable C2 do not behave unintentionally when the coupler 5 is not connected to the dedicated tool.

The coupler 5 has a square prism shape and includes a thin portion 5a on the cable C2 side, a thick portion 5b on the tip side, and a hook-shaped claw portion 5c extending from the thick portion 5b to the tip side. A thick portion is inserted into the coupler inserting portion 6 and held. The claw portion 5c is an engagement claw that engages with a claw portion (not shown) on the dedicated tool side to prevent the coupler 5 from falling off from the dedicated tool.

In the case of this embodiment, the fuse holding portion 4 and the coupler insertion portion 6 are one member, and the holder 7 integrally includes the fuse holding portion 4 and the coupler insertion portion 6 . 11 is a plan view of the holder 7, and FIG. 12 is a perspective view of the holder 7. FIG.

The fuse holding portion 4 has a wall portion 41 defining a housing space 40 for the fuse 2B and a bottom portion 42 . The accommodation space 40 holds the fuse 2B in a posture in which the longitudinal direction L1 of the fuse 2B intersects the insertion direction Id1 of the fuse 2A. In the case of this embodiment, the fuse 2B is held so that the longitudinal direction L1 of the fuse 2B is orthogonal to the insertion direction Id1 of the fuse 2A, and the longitudinal direction L1 of the fuse 2B is oriented in the d2 direction. The fuse 2A is inserted into the fuse insertion portion 3 in a vertical position (standing position), while the fuse 2B is held in a horizontal position (lying position).

The accommodation space 40 is open upward and has a left space 40a in which the head 20 of the fuse 2B is accommodated and a right space 40b in which the body 21 is accommodated. The wall portion 41 has a rectangular cylindrical shape, and has a left wall portion 41a, a right wall portion 41b, a front wall portion 41c, and a rear wall portion 41d. A plurality of linear ribs 44 extending in the depth direction (d3 direction in this embodiment) of the accommodation space 40 are provided on the inner surface 43 of the wall portion 41 so as to be spaced apart in the circumferential direction of the accommodation space 40 . The fuse 2B is fitted into the housing space 40 by the rib 44 coming into contact with the fuse 2B.

Cutouts 45 and 46 are formed in the left wall portion 41a and the right wall portion 41b, respectively. The notch 45 is formed to open the upper portion of the left wall portion 41a in the d1 direction central portion, and the notch 46 is formed to open the upper portion of the right wall portion 41b in the d1 direction central portion. The notch 45 increases the amount of exposure of the head 20 of the fuse 2B held by the fuse holding portion 4, and the notch 46 increases the amount of exposure of the bottom surface 21a of the fuse 2B.

The coupler inserting portion 6 has a wall portion 61 defining an accommodation space 60 for the coupler 5 and a bottom portion 62 . The accommodation space 60 is open upward. The wall portion 61 has a rectangular cylindrical shape, and has a left wall portion 61a, a right wall portion 61b, a front wall portion 61c, and a rear wall portion 61d. A slit 63 is formed in the right wall portion 61b to avoid interference between the claw portion 5c and the right wall portion 61b. The coupler 5 is inserted into the coupler inserting portion 6 in the inserting direction Id2 (FIG. 4) from above the coupler inserting portion 6 and held therein. The insertion direction Id2 is the d3 direction and parallel to the insertion direction Id1.

The holder 7 is arranged adjacent to the fuse box 8 and is fixed to the rear wall of the fuse box 8 in this embodiment. The rear wall of the fuse box 8 is provided with an engaging portion 8b, and the holder 7 is provided with an engaging portion 7a. The holder 7 is fixed to the fuse box 8 by engaging the engaging portion 7a with the engaging portion 8b. The engaging portion 7a is formed integrally with the fuse holding portion 4, and particularly formed integrally with the front wall portion 41c.

The electrical component arrangement structure 1 having the above configuration has the advantage that the fuse 2A in use and the fuse 2B as a spare fuse can be visually distinguished easily.

Specifically, the fuse in use and the spare fuse are generally the same fuse, such as the fuse 2A and the fuse 2B. However, in the present embodiment, the fuse 2B is held in the fuse holding portion 4 in such a posture that the longitudinal direction L1 of the fuse 2B intersects the insertion direction Id1 of the fuse 2A, and the postures of the fuse 2A and the fuse 2B are different. ing. As best shown in FIG. 3, the fuse 2A inserted in the fuse insertion portion 3 and the fuse 2B held in the fuse holding portion 4 are viewed in the insertion direction Id1, which is the viewing direction of the worker during the replacement work. In this case, the shape of the head 20 of the fuse 2A appears in a plan view, and the shape of the head 20 and the body 21 of the fuse 2B appear in a side view. Since the long side of the fuse 2B is exposed and the short side of the fuse 2A is exposed, the fuse 2B appears longer than the fuse 2A. Especially in this embodiment, since the fuse 2B is held in a posture in which the longitudinal direction L1 of the fuse 2B is orthogonal to the insertion direction Id1 of the fuse 2A, the fuse 2B is held in a posture in which the fuse 2B appears to be the longest.

Therefore, the difference between the fuse 2A and the fuse 2B can be seen at a glance, making it easier to visually distinguish between the two. In addition, since the fuse 2A and the fuse 2B have different postures, they can be easily illustrated in a maintenance manual or the like, and can be easily understood by the operator.

The coupler inserting portion 6 is arranged adjacent to the fuse holding portion 4 . In general, if the mounting portions of parts are adjacent to each other, workers may misunderstand. However, in this embodiment, the insertion direction Id2 of the coupler 5 intersects the longitudinal direction L1 of the fuse 2B held by the fuse holding portion 4, and is particularly orthogonal. Since the mounting attitudes of the coupler 5 and the fuse 2B with respect to the coupler insertion portion 6 and the fuse holding portion 4 are greatly different, it is possible to prevent the coupler insertion portion 6 from being mistaken for the fuse holding portion 4.例文帳に追加

The coupler inserting portion 6 is arranged between the fuse inserting portion 3 and the fuse holding portion 4 in the d2 direction. Of these three configurations, the fuse holding portion 4 is positioned on the left outer side, so that the coupler inserting portion 6 and the coupler 5 inserted into the coupler inserting portion 6 are relatively unobstructed when the fuse 2B is attached and detached. The coupler 5 has a narrow portion 5a and a thick portion 5b. As shown in FIG. 4, the thick portion 5b is located at a height H2, which is lower than the height H1 of the upper end of the fuse 2B. When attaching and detaching the fuse 2B, the space for inserting the operator's finger is widened, and the presence of the coupler 5 is relatively unobtrusive.

As shown in FIGS. 4 and 5 , the claw portion 5 c of the coupler 5 faces the fuse insertion portion 3 when the coupler 5 is inserted into the coupler insertion portion 6 . Since the claw portion 5c is surrounded by the coupler inserting portion 6 and the fuse inserting portion 3, it is possible to prevent breakage and protect it. In addition, the coupler insertion portion 6 may be configured so that the claw portion 5 c faces the fuse holding portion 4 . However, the fuse insertion portion 3 is long in the insertion direction Id1, the insertion direction Id2 of the coupler 5 is parallel to the insertion direction Id1, and the claw portion 5c extends in the Id2 direction. With the configuration in which the portion 5c faces the fuse insertion portion 3, a sufficient length in the d3 direction can be secured for the range surrounding the claw portion 5c, and the protective performance can be improved.

Since the holder 7 integrally includes the fuse holding portion 4 and the coupler insertion portion 6, the number of parts can be reduced, and a more compact electrical component arrangement structure 1 can be provided. Further, as shown in FIG. 4, the width W1 of the holder 7 in the d2 direction is shorter than the width W2 of the fuse box 8, and the holder 7 is within the width W2 of the fuse box 8 in the d2 direction. A more compact electrical component arrangement structure 1 can be provided.

The holder 7 is fixed to the fuse box 8 via the engaging portions 7a and 8b, and as best shown in FIG. is formed in In the holder 7, the degree of constraint on the fuse holding portion 4 side can be increased relative to the coupler insertion portion 6, and the fuse 2B can be prevented from falling off from the fuse holding portion 4 due to vibration or the like.

The fuse 2B is held by a plurality of ribs 44 within the accommodation space 40. As shown in FIG. Since the fuse 2B is held by the line contact between the rib 44 and the fuse 2B, the fuse 2B can be firmly held while reducing the detachment resistance of the fuse 2B. Further, when the fuse 2B is held by surface contact with the wall portion 41, rattling may occur due to deterioration over time.

7 to 9, notches 45 and 46 are formed in the walls 41a and 41b that define the housing space 40. As shown in FIGS. An operator can easily grasp the fuse 2B through the cutouts 45 and 46 and easily take out the fuse 2B. The notch may be provided only in one of the wall portions 41a and 41b located at the end of the fuse 2B in the longitudinal direction L1. By providing the cutouts 45 and 46, the operator can easily pick up the fuse 2B by sandwiching the head 20 and the bottom 21a of the fuse 2B, and can easily take out the fuse 2B.
