[0010] Specific embodiments of the present invention will be described below with reference to the figures. The electrical junction box houses electronic components and is located in the engine compartment of the vehicle. The fuse module of this embodiment is housed in this electrical junction box.

[0011] For the sake of clarity, the terms "front," "back," "left," "right," "up," and "down" are defined below as shown in Figures 1 to 5. The "front-back direction," "left-right direction," and "up-down direction" are orthogonal to each other. The left-right direction corresponds to the "alignment direction" in this invention.

[0012] As shown in Figures 1 and 2, the fuse module 1 comprises a fuse 2 as an electronic component, a housing 3 for detachably housing the fuse 2, and a first magnet 4 and a second magnet 5. As shown in Figure 3, the fuse 2 comprises a fusible body 21 as the main body of an electronic component that melts when an overcurrent flows, a resin holding part 22 that houses the fusible body 21, and a pair of terminals 23, 23 that are connected to the fusible body 21 and protrude from the holding part 22.

[0013] The holding portion 22 is made of resin or the like and is provided in a substantially flat plate shape with the front-to-back direction being the thickness direction. The holding portion 22 is provided in a substantially rectangular flat plate shape when viewed from the front. The fusible body 21 is held approximately in the center of this holding portion 22. The upper ends of the pair of terminals 23, 23 are housed within the holding portion 22 and are connected to both ends of the fusible body 21, respectively. The lower ends of the pair of terminals 23, 23 protrude from the holding portion 22. In this embodiment, the pair of terminals 23, 23 are provided in a substantially flat plate shape with the front-to-back direction being the thickness direction and protrude side by side in the left-to-right direction.

[0014] As shown in Figure 1, the housing section 3 is provided in a roughly rectangular parallelepiped shape and houses the fuse 2. In this embodiment, the housing section 3 houses one fuse 2. The housing section 3 has a roughly rectangular cylindrical first housing section 31 provided at its lower end, a partition section 32 (Figure 4) that divides the inside of the first housing section 31 in the left-right direction, and a roughly rectangular cylindrical second housing section 33 provided above the first housing section 31. The first housing section 31 is provided in a rectangular cylindrical shape that is elongated in the left-right direction, and houses the terminals 23 of the fuse 2 as shown in Figure 4. In addition, a pair of connectors 6, 6 (see Figure 1) that are connected to the terminals 23 are detachably housed in the first housing section 31. The pair of connectors 6, 6 are attached to the ends of the electric wire 7.

[0015] As shown in FIG. 4, the partition portion 32 divides the rectangular tube-shaped first accommodation portion 31 in the left-right direction, and a pair of connectors 6, 6 are accommodated on the right side and the left side of the partition portion 32, respectively. The partition portion 32 is provided with a pair of locking arms 321, 321 that respectively lock with the pair of connectors 6, 6.

[0016] The second accommodation portion 33 is provided in a rectangular tube shape with a long left-right direction, and the holding portion 22 of the fuse 2 is accommodated therein. The width of the second accommodation portion 33 in the left-right direction is provided to be larger than the width of the first accommodation portion 31 in the left-right direction. The outer surfaces of the second accommodation portion 33 facing each other in the left-right direction protrude outward in the left-right direction from the outer surfaces of the first accommodation portion 31 facing each other in the left-right direction. As shown in FIG. 1, the widths of the first accommodation portion 31 and the second accommodation portion 33 in the front-rear direction are provided to be the same, and the outer surfaces of the first accommodation portion 31 and the second accommodation portion 33 facing each other in the front-rear direction are provided on the same plane. An opening 332 is provided in the wall portion of the second accommodation portion 33 facing each other in the front-rear direction, and the holding portion 22 of the fuse 2 can be visually recognized through the opening 332.

[0017] The first magnet 4 is fixed to the fuse 2. In the present embodiment, the first magnet 4 is fixed to a pair of outer surfaces of the holding portion 22 facing each other in the left-right direction, respectively. In the present embodiment, as shown in FIG. 4, a plurality of press-fitting protrusions 211 are provided on the outer surfaces of the holding portion 22 facing each other in the left-right direction, and the first magnet 4 is fixed to the fuse 2 by being press-fitted into the press-fitting holes 41 provided in the first magnet 4.

[0018] Also, in the present embodiment, as shown in FIG. 2, two first magnets 4, 4 are arranged side by side in the front-rear direction on the right outer surface of the holding portion 22. In the present embodiment, among the two first magnets 4, 4 fixed to the right outer surface of the holding portion 22, the front one is arranged such that the upper side is the S pole and the lower side is the N pole, and the rear one is arranged such that the upper side is the N pole and the lower side is the S pole.

[0019] Two first magnets 4, 4 are also arranged side by side in the front-to-back direction on the left outer surface of the holding portion 22. In this embodiment, of the two first magnets 4 fixed to the left outer surface of the holding portion 22, the front magnet is positioned so that its upper side is the south pole and its lower side is the north pole, while the rear magnet is positioned so that its upper side is the north pole and its lower side is the south pole.

[0020] The second magnet 5 is fixed to the housing 3. In this embodiment, the second magnet 5 is fixed to a pair of opposing inner surfaces of the second housing 33 in the left-right direction. In this embodiment, as shown in Figure 4, a plurality of press-fitting protrusions 331 are provided on the opposing inner surfaces of the second housing 33, and the second magnet 5 is fixed to the second housing 33 by being press-fitted into press-fitting holes 51 provided in the second magnet 5.

[0021] Furthermore, in this embodiment, as shown in Figure 2, two second magnets 5, 5 are arranged side by side in the front-to-back direction on the right inner surface of the second housing section 33. In this embodiment, of the two second magnets 5, 5 fixed to the right inner surface of the second housing section 33, the front magnet is positioned so that the upper side is the north pole and the lower side is the south pole, while the rear magnet is positioned so that the upper side is the south pole and the lower side is the north pole.

[0022] Two second magnets 5, 5 are also arranged side by side in the front-to-back direction on the left inner surface of the second housing section 33. In this embodiment, of the two second magnets 5, 5 fixed to the left inner surface of the second housing section 33, the front magnet is positioned so that its upper side is the north pole and its lower side is the south pole, while the rear magnet is positioned so that its upper side is the south pole and its lower side is the north pole.

[0023] As explained above, when the first magnet 4 and the second magnet 5 are arranged, as shown in Figure 4, when a fuse 2 of the correct capacity is inserted, the first magnet 4 and the second magnet 5 will face each other in the left-right direction. At that time, the opposite magnetic poles of the first magnet 4 and the second magnet 5 will face each other in the left-right direction.

[0024] On the other hand, as shown in Figure 5, a first magnet 4B with a different magnetic pole configuration than the first magnet 4 fixed to the fuse 2 is fixed to the fuse 2. In this embodiment, the north pole of the first magnet 4B is positioned where the south pole of the first magnet 4 is positioned, and the south pole of the first magnet 4B is positioned where the north pole of the first magnet 4 is positioned.

[0025] Next, the procedure for installing the fuse 2 into the housing section 3 with the above-described configuration will be explained. First, the fuse 2 is inserted through the insertion opening, which is the upper opening of the second housing section 33. As shown in Figure 4, when a fuse 2 of the correct capacity is installed, the lower side of the first magnet 4 and the upper side of the second magnet 5 face each other in the left-right direction during insertion. That is, since the same magnetic poles of the first magnet 4 and the second magnet 5 face each other in the left-right direction, there is resistance during insertion. However, as the fuse 2 is further inserted, the different magnetic poles of the first magnet 4 and the second magnet 5 face each other in the left-right direction, so the fuse 2 can be installed in the second housing section 33 without being pushed back into the insertion opening.

[0026] On the other hand, as shown in Figure 5, if a fuse 2B of the wrong capacity is installed, the lower side of the first magnet 4B and the upper side of the second magnet 5 will face each other in the left-right direction when inserted. That is, the different magnetic poles of the first magnet 4 and the second magnet 5 will face each other in the left-right direction. Furthermore, when the fuse 2B is inserted, the same magnetic poles of the first magnet 4 and the second magnet 5 will face each other in the left-right direction, generating a repulsive force that pushes the fuse 2B back into the insertion slot, preventing it from being housed in the second housing section 33.

[0027] According to the embodiment described above, the first magnet 4 is fixed to the fuse 2, and the second magnet 5 is fixed to the housing 3. The first magnet 4 and the second magnet 5 are fixed in positions opposite to each other in the left-right direction when the fuse 2 is housed in the housing 3. As a result, if an attempt is made to house a fuse 2B of the wrong capacity, the same magnetic poles of the first magnet 4 and the second magnet 5 will repel each other in the left-right direction, preventing the fuse 2B from being housed in the housing 3, thus preventing incorrect assembly. Conversely, if an attempt is made to house a fuse 2 of the correct capacity, the different magnetic poles of the first magnet 4 and the second magnet will attract each other in the left-right direction, allowing the fuse 2 to be housed in the housing 3.

[0028] In other words, by varying the arrangement of the S and N poles of the second magnet 5 fixed to the housing 3 for each capacity, and by changing the number of the second magnet 5, and by fixing the first magnet 4 so that the magnetic poles facing the second magnet 5 are different for the fuse 2 of the correct capacity, it is possible to prevent the insertion of a fuse 2 of the wrong capacity.

[0029] According to the embodiment described above, the first magnet 4 is fixed to both sides of the holding portion 22 in the left-right direction, which is the direction in which the pair of terminals 23, 23 are aligned. This makes it possible to make the fuse 2 thinner in the front-rear direction.

[0030] Furthermore, the present invention is not limited to the embodiments described above, and can be modified, improved, etc., as appropriate. In addition, 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.

[0031] In the embodiment described above, the electronic component consisted of a fuse, but it is not limited to this. The electronic component may also consist of a relay.

[0032] In the embodiment described above, the first magnet 4 and the second magnet 5 were fixed to the fuse 2 and the housing 3 so as to be opposite each other in the left-right direction when housed, but this is not the only configuration. The first magnet 4 and the second magnet 5 may also be fixed to the fuse 2 and the housing 3 so as to be opposite each other in the front-back direction or the up-down direction.

[0033] In the embodiment described above, one fuse 2 was housed in one housing 3, but this is not limited to this. Multiple fuses 2 may be housed in the housing 3.

[0034] In the embodiment described above, the housing section 3 was configured to detachably house a connector 6 connected to the fuse 2, but it is not limited to this. The housing section 3 may also house a busbar connected to the fuse 2.

[0035] In the embodiment described above, the fuse 2 was press-fitted into the first magnet 4 and the housing 3 was press-fitted into the second magnet 5 for fixation, but this is not the only method. It is sufficient that the first magnet 4 and fuse 2, and the second magnet 5 and housing 3 are each fixed, and they may be fixed with adhesive.
