For ease of explanation, the front-rear direction, left-right direction, and up-down direction are defined below as shown in FIG. 1. The front-rear direction, left-right direction, and up-down direction are perpendicular to one another.

[0012] 1, the fuse box 1 includes a fuse 2 as an example of an electrical component, a pair of bus bars 3, a housing 5 that accommodates the fuse 2, and a bracket 8. In the fuse box 1, an electric wire terminal TA connected to an end of an electric wire W shown in FIG. 8 is electrically connected to a fuse terminal 22 shown in FIG. 3 via the bus bar 3.

[0013] 3, the fuse 2 has a cylindrical fuse body 21 extending in the left-right direction and fuse terminals 22 protruding from both ends of the fuse body 21. Each fuse terminal 22 has a substantially square plate shape and has a through-hole 22a formed in the center. A bolt B is inserted into this through-hole 22a to fasten the fuse 2 to the housing 5.

[0014] 4, the housing 5 has a bottomed box-shaped fuse accommodating portion 51 that accommodates the fuse 2, and a fixing wall portion 4 that extends from the fuse accommodating portion 51, and is made of insulating resin such as synthetic resin. In the present disclosure, the bottomed box-shaped configuration may be any shape that has at least a bottom and side surfaces, and the shapes of the bottom and side surfaces are not limited to rectangular.

[0015] The fuse accommodating section 51 is an example of an electrical component accommodating section. The fuse accommodating section 51 has a generally rectangular parallelepiped shape with an open top, and a recess 51a for accommodating the fuse main body 21 is provided at the center of the bottom 511 in the front-rear and left-right directions. Nuts 52 that screw onto bolts B are embedded in the bottom 511 on the left and right sides of the recess 51a.

[0016] The fixing wall 4 has a wall main body 41 in the shape of a substantially rectangular plate, and the rear wall of the fuse accommodating portion 51 stands upright from the bottom 511 along the vertical direction, which is the direction in which the fuse 2 is accommodated. The fixing wall 4 stands upright adjacent to the fuse accommodating portion 51. The fixing wall 4 has an opening 7 cut out in a U-shape in the center of the upper side of the wall main body 41.

[0017] As shown in FIG. 2 , the wall main body 41 has, on its rear surface, a pair of guide grooves 42, a pair of guide grooves 43, and a pair of bosses 44. The left and right side edges of the plate-shaped bracket 8 are inserted into and held in the guide grooves 42 and 43. The boss 44 is a cylindrical member that protrudes rearward, i.e., toward the bracket 8, from the rear surface of the wall main body 41. The boss 44 is inserted into the boss insertion portion 9b of the vehicle-side fixing member 9 through the insertion hole 8b of the bracket 8. The pair of guide grooves 42, the pair of guide grooves 43, and the pair of bosses 44 are each arranged symmetrically with respect to a line that passes through the fastening hole 8a in the up-down direction when the bracket 8 is held by the wall main body 41.

[0018] As shown in Fig. 5, a pair of bus bars 3 are provided symmetrically. The bus bar 3 has a bus bar body 31 which is a bent conductive metal plate, and a bolt 32 fixed to the bus bar body 31. The bus bar body 31 has a first portion 311 extending in the up-down direction and a second portion 312 extending in the front-rear and left-right directions.

[0019] The first portion 311 is provided with a bolt 32 that extends in the front-rear direction and to which an electric wire terminal TA is connected. The first portion 311 and the bolt 32 function as an electric wire connection portion that is connected to an electric wire W. The second portion 312 is provided with a through hole 33 through which a bolt B is inserted. The portion of the second portion 312 that is provided with the through hole 33 functions as a terminal connection portion that is connected to the fuse terminal 22.

[0020] As shown in FIG. 6 , the bracket 8 has a flat plate-like shape and a bracket main body 81 that extends in the left-right direction and the up-down direction, which is the extension direction of the fixing wall 4. The bracket 8 is fixed to the rear side of the fixing wall 4. The bracket 8 is formed, for example, by stamping a metal plate, but may also be formed from a resin that is more rigid than the fixing wall 4 of the housing 5. The bracket main body 81 has a substantially rectangular narrow portion 82 and a wide portion 83 that is wider than the narrow portion 82, and both ends in the width direction, i.e., the left-right direction, are stepped. The bracket 8 has a fastening hole 8a above the narrow portion 82 and located centrally in the left-right direction. The fastening hole 8a functions as a first fastening hole through which a bolt 6 is inserted in the thickness direction of the bracket 8, i.e., the front-rear direction, and fastens the bolt 6 to the vehicle-side fixing member 9.

[0021] 7, the vehicle-side fixing member 9 has a flat plate shape, and has an insertion hole 9a, through which the bolt 6 is inserted, provided at the center in the left-right direction at the top, and a pair of boss insertion portions 9b, through which the pair of bosses 44 are inserted, provided below the insertion hole 9a. The vehicle-side fixing member 9 is an example of an object to which the fuse box 1 is attached.

[0022] Next, the assembly of the fuse box 1 will be described.

[0023] First, the worker places a pair of bus bars 3 on the housing 5. Each bus bar 3 is placed on the housing 5 so that the first portion 311 contacts the front surface of the fixing wall portion 4 and the through hole 33 of the second portion 312 is positioned on the nut 52 on the bottom portion 511. Next, the worker places the fuse 2 on the bus bar 3. The fuse 2 is positioned so that the fuse main body 21 is accommodated in the recess 51a of the housing 5 and the through hole 22a of each fuse terminal 22 corresponds to the position of the through hole 33 of the bus bar 3. As a result, the nuts 52, the through holes 33, and the through holes 22a are aligned vertically and overlapping each other. Then, the bolt B is inserted through the through hole 33 and the through hole 22a and screwed into the nut 52, thereby fastening and fixing the fuse 2 and bus bar 3 to the housing 5.

[0024] The worker attaches the bracket 8 to the rear surface of the fixing wall 4 of the housing 5. The bracket 8 is inserted into the insertion holes 8b so that the bosses 44 protruding rearward from the housing 5 contact the upper edges of the insertion holes 8b, and the front surface of the bracket body 81 abuts against the rear surface of the fixing wall 4. At this time, the bracket 8 is positioned so that the left and right shoulders 821 of the narrow portion 82 are positioned below the pair of guide grooves 42 and the left and right shoulders 831 of the wide portion 83 are positioned below the pair of guide grooves 43. When the worker slides the bracket 8 upward in this state, the bracket 8 is guided by the pair of guide grooves 42 and the pair of guide grooves 43 and moves upward, until the shoulders 831 abut against the upper walls of the guide grooves 43. In this state, the bracket 8 is clamped between the guide grooves 42, 43 and fixed to the fixing wall 4 of the housing 5.

[0025] Next, the connection and fixation of the fuse box 1 assembled as above to the vehicle-side fixing member 9 will be described.

[0026] The worker brings the bracket 8 of the fuse box 1 close to the vehicle-side fixing member 9. The bracket 8 is positioned so that the fastening holes 8a of the bracket 8 are aligned with the insertion holes 9a of the vehicle-side fixing member 9 in the front-rear direction and so that the pair of bosses 44 are inserted into the pair of boss insertion portions 9b. The worker then inserts the bolts 6 from the front into the fastening holes 8a and the insertion holes 9a and screws them into nuts N1 (see FIG. 8 ) arranged on the rear side of the vehicle-side fixing member 9. When the bolts 6 are screwed into the nuts N1, the housing 5 is fastened to the vehicle-side fixing member 9 via the bracket 8 held on the rear surface of the fixing wall 4. Note that the bolts 6 may also be inserted in the opposite direction, that is, from the rear side of the bracket 8 and vehicle-side fixing member 9, and screwed into the nuts N1 arranged on the front side.

[0027] When the bracket 8 fixed to the fixing wall 4 of the housing 5 is connected to the vehicle-side fixing member 9 with the bolt 6, torque generated in the bolt 6 tends to rotate the bracket 8. This torque is received by the pair of bosses 44 inserted into the pair of boss insertion portions 9b of the vehicle-side fixing member 9. Therefore, when the housing 5 is attached to the vehicle-side fixing member 9 with the bolt 6, rotation of the housing 5 fixed to the bracket 8 can be suppressed. Therefore, even if the fuse box 1 connected to the vehicle side is affected by vehicle vibrations or the like, rattles can be suppressed.

[0028] Next, the worker fastens the electric wire terminals TA. The electric wire terminals TA are round terminals with through holes, and are attached to one end of the electric wires W. As shown in FIG. 8 , each electric wire terminal TA is clamped and fixed between the first portion 311 of the bus bar 3 and the nut N2, with a bolt 32 inserted into the through hole. Fastening the electric wire terminals TA to the bus bar 3 in this manner electrically connects the bus bar 3 to an external load connected to the other end of the electric wire W.

[0029] When fixing the fuse box 1 to the vehicle-side fixing member 9 by tightening the bolts 6 and tightening the electric wire terminals TA to the bolts 32 of the bus bar 3, the worker tightens the bolts 6 from the direction of the arrow D1 and tightens the electric wire terminals TA from the direction of the arrow D2, as shown in Fig. 8. In this way, the tightening direction of the electric wire terminals TA fastened to the bolts 32 of the bus bar 3 and the tightening direction of the bolts 6 are both the front-to-rear direction and coincide with each other, so the worker can perform installation without changing his / her working posture, improving workability.

[0030] In addition, in the fuse box 1, the fixing wall 4 of the housing 5 is fastened to a vehicle-side fixing member 9 via a bracket 8 by a bolt 6 arranged in an opening 7. Therefore, as shown in FIG. 8, the bolt 6 is prevented from protruding directly above the fuse 2, which makes it possible to replace the fuse 2 without removing the fuse box 1, improving workability.

[0031] As described above, according to the fuse box 1 of this embodiment, the housing 5 accommodating the fuse 2 is fastened to the vehicle-side fixing member 9 via the bracket 8 fixed to the fixing wall 4. With this configuration, the housing 5 and the vehicle-side fixing member 9 can be connected in a direction corresponding to the extending direction of the fixing wall 4. Therefore, by appropriately setting the extending direction of the fixing wall 4 according to the requirements of the vehicle, the mounting position of the fuse box 1 on the vehicle can be freely set without being restricted by the connecting direction with the vehicle.

[0032] Furthermore, with the fuse box 1, the fixing wall 4 is erected in the vertical direction, which is the direction in which the fuse 2 is accommodated, so the bracket 8 can be attached along the accommodation direction and fastened to the vehicle-side fixing member 9. Therefore, compared to an electrical component storage box in which a portion of the housing 5 that accommodates the fuse 2 protrudes, for example, in the front-to-rear direction to provide a vehicle coupling portion, and a fastening member is inserted through the vehicle coupling portion to secure the box to the vehicle, the amount of protrusion of the vehicle coupling portion can be reduced, thereby enabling the fuse box to be made more compact.

[0033] The present invention is not limited to the above-described embodiments, and can be appropriately modified, improved, etc. In addition, the material, shape, dimensions, numerical values, form, number, location, etc. of each component in the above-described embodiments are arbitrary and not limited as long as they can achieve the present invention.

[0034] In the above-described embodiment, the fixing wall portion 4 is formed by extending the side wall of the fuse accommodating portion 51 upward, but the fixing wall portion may be formed by extending the bottom wall of the fuse accommodating portion 51 in the front-to-back or left-to-right direction, as long as it is extended into the fuse accommodating portion 51.
