Description

[Technical Field]

[0001] The present invention relates to an electrical junction box. [Background technology]

[0002] A conventional electrical junction box as described above is proposed in Patent Document 1. The electrical junction box of Patent Document 1 contains a block housing (component holding portion) that houses electronic components such as fuses, a bolt block (bolts), and an FL bolt block attachment / detachment portion (bolt holding portion) that holds the bolt block.

[0003] In conventional electrical junction boxes, the direction in which fuses are attached to and detached from the block housing is the same as the direction in which the bolts of the bolt block protrude. Therefore, when accommodating multiple bolt blocks, the bolt blocks must be arranged in a direction that intersects with the attachment and detachment direction. This results in a large projected area of ​​the FL bolt block attachment and detachment section as seen from the attachment and detachment direction, resulting in poor space efficiency.

[0010] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An electric junction box 1 is mounted with electronic components such as fuses and relays and is disposed in an engine compartment of a vehicle.

[0011] For the sake of convenience, the following definitions are used for "front," "rear," "left," "right," "upper," and "lower" as shown in Figures 1 to 4. The "front-rear direction," "left-right direction," and "upper-lower direction" are perpendicular to one another. The upper-lower direction corresponds to the "attachment / detachment direction" of the present invention, the front-rear direction corresponds to the "arrangement direction" of the present invention, and the left-right direction corresponds to the "protrusion direction" of the present invention.

[0012] As shown in Fig. 1, the electrical junction box 1 includes a component holding section 2 that holds electronic components, a plurality of bolt blocks 3, a bolt holding section 4 that holds the plurality of bolt blocks 3, and a case 5 that houses the component holding section 2 and the bolt holding section 4. Also, as shown in Fig. 2, the electrical junction box 1 includes a bus bar 6 connected to the electronic components, terminals 7R, 7L, and electric wires 8 to which the terminals 7R, 7L are attached.

[0013] As shown in FIGS. 1 to 3, the component holder 2 is made of insulating synthetic resin and is provided with a plurality of accommodation chambers 21 for accommodating electronic components. Each accommodation chamber 21 is formed in a substantially rectangular tubular shape with openings in the vertical direction. Electronic components are detachably held in the accommodation chambers 21 through the upper opening. That is, the vertical direction is the direction in which electronic components are attached to and detached from the component holder 2. In this embodiment, the plurality of accommodation chambers 21 are arranged side by side in the front-to-rear and left-to-right directions.

[0014] 2, the bolt block 3 has a conductive bolt 31, a nut (not shown) that is screwed onto the bolt 31, and a substantially rectangular parallelepiped block portion 32. The block portion 32 is made of synthetic resin and is attached to the head of the bolt 31. In this embodiment, two bolt blocks 3 are provided.

[0015] The bolt holding portion 4 is provided with two storage chambers 41, 41 that store the block portions 32 of the bolt block 3. Each of the two storage chambers 41, 41 is formed in a substantially rectangular cylindrical shape with openings in the left and right directions. When the block portion 32 is stored through the opening on the right side of the storage chamber 41, the bolt 31 is held so that it protrudes to the right from the bolt holding portion 4. The two storage chambers 41, 41 are arranged side by side in the vertical direction, and the bolt holding portion 4 holds a plurality of bolt blocks 3 lined up along the vertical direction.

[0016] The right side surface of the block portion 32 is exposed from the right opening of the accommodation chamber 41. A bus bar 6 connected to an electronic component is placed on the right side surface of the block portion 32. The bolt 31 passes through a through hole or a notch (not shown) provided in the bus bar 6 and protrudes to the right of the bus bar 6.

[0017] The component holder 2 and bolt holder 4 are arranged side by side in the front-to-rear direction. In this embodiment, the component holder 2 is arranged on the front side, and the bolt holder 4 is arranged on the rear side. The bolt holder 4 is provided so as to protrude upward from the component holder 2. The component holder 2 and the bolt holder 4 may be integrally molded from resin, or may be provided as separate parts.

[0018] As shown in FIG. 1 , the case 5 includes a frame 51 made of insulating synthetic resin, an upper cover (not shown), a lower cover 52, and side covers 53. The frame 51 has a front wall 511 and a rear wall 512 that face each other and are spaced apart in the front-to-rear direction, a right wall 513 that connects the right ends of the front wall 511 and the rear wall 512, and a left wall 514 that connects the left ends of the front wall 511 and the rear wall 512, and is formed in a substantially rectangular tubular shape with openings in the vertical direction. The component holder 2 is housed within the rectangular tubular frame 51. The lower end of the bolt holder 4 is housed within the frame 51, but the two bolts 31 are located above the upper end of the frame 51.

[0019] The upper cover closes the upper opening of the frame 51. The lower cover 52 closes the lower opening of the frame 51. In this embodiment, a side cover 53 is attached to a rear wall portion 512 of the frame 51. The upper end of the side cover 53 protrudes upward beyond the upper end of the frame 51 and covers the rear side of the bolt holding portion 4 and the bolt 31. As shown in FIG. 4 , when the side cover 53 is removed, the terminals 7R, 7L fastened to the bolt 31, the electric wires 8 attached to the terminals 7R, 7L, the bolt holding portion 4, and the bolt 31 are exposed.

[0020] The two terminals 7R, 7L are fastened to two bolts 31, 31, respectively. As shown in FIG. 2 and other figures, the terminals 7R, 7L each have a bolt connection portion 71R, 71L, a coupling portion 72R, 72L, and an electric wire connection portion 73R, 73L, and are provided in a substantially L-shape when viewed from above (see FIG. 3). The bolt connection portions 71R, 71L are overlapped with the bus bar 6, and have notches 74R, 74L at their front ends. The bolts 31 are inserted into the notches 74R, 74L.

[0021] The connecting portions 72R, 72L are continuous with the rear ends of the bolt connecting portions 71R, 71L and face the rear outer surface of the bolt holding portion 4 in the front-rear direction. The connecting portion 72L connected to the upper bolt 31 is provided with a longer width in the left-right direction than the connecting portion 72R connected to the lower bolt 31. In other words, the left end of the connecting portion 72L connected to the upper bolt 31 is located to the left of the left end of the connecting portion 72R connected to the lower bolt 31.

[0022] The electric wire connection portions 73R, 73L are connected to the lower sides of the coupling portions 72R, 72L and are connected to the electric wires 8. The electric wire connection portion 73L connected to the upper bolt 31 is disposed to the left of the electric wire connection portion 73R connected to the lower bolt 31. One end of the electric wire 8 is connected to the electric wire connection portions 73R, 73L and is drawn out from the lower sides of the electric wire connection portions 73R, 73L.

[0023] Next, the bolt tightening procedure for the terminals 7R, 7L described above will be described. First, the terminals 7R, 7L are brought close to each other from the rear side of the bolt 31, and the bolt 31 is inserted from the front end of the notch 74R, 74L, so that the bolt connection portions 71R, 71L overlap the bus bar 6. When the bolt 31 is inserted up to the rear end of the notch 74R, 74L, the connecting portions 72R, 72L and the rear outer surface of the bolt holding portion 4 face each other in the front-to-rear direction. Next, when the nut is screwed onto the bolt 31, the terminals 7R, 7L and the bus bar 6 are sandwiched between the block portion 32 and the nut. This allows the terminals 7R, 7L and the bus bar 6 to be electrically connected.

[0024] In the conventional case, when the bolt 31 is held so that it protrudes upward and multiple bolts 31 are aligned in the left-right direction, the length of the bolt holding portion 4 in the left-right direction becomes long when viewed from the top-bottom direction. In contrast, according to the above-described embodiment, the multiple bolts 31 are held so that they protrude from the bolt holding portion 4 in a direction intersecting the up-down direction (the left-right direction in this embodiment), and the bolt holding portion 4 holds two bolts 31 aligned in the up-down direction. This reduces the projected area of ​​the bolt holding portion 4 when viewed from the top-bottom direction, thereby improving space efficiency. In other words, compared to the conventional case, the electrical junction box 1 of this embodiment creates free space, as shown by the diagonally shaded area in FIG. 3 . This free space can be used to mount other components or the frame 51 can be reshaped to eliminate the free space, thereby improving space efficiency. This embodiment is particularly useful when the electrical junction box 1 is installed in a space with sufficient vertical space but limited front-to-back or left-to-right space.

[0025] According to the embodiment described above, the two bolts 31, 31 are held so as to protrude rightward from the bolt holding portion 4. This allows the electrical junction box 1 to be made smaller in the front-to-rear direction than when the two bolts 31, 31 are held so as to protrude rearward from the bolt holding portion 4.

[0026] According to the above-described embodiment, the terminals 7R, 7L have the bolt connection portions 71R, 71L, the connecting portions 72R, 72L facing the outer surface of the rear side of the bolt holding portion 4 in the front-rear direction, and the wire connection portions 73R, 73L continuing downward from the connecting portions 72R, 72L and connected to the wires 8. As a result, even if the bolt 31 protrudes to the right, the wires 8 can be drawn out from the rear side of the case 5 without increasing the space in the front-rear direction.

[0027] According to the above-described embodiment, the bolt connection portions 71R, 71L are provided at their front ends with notches 74R, 74L into which the bolt 31 is inserted. As a result, even if there is no space in the protruding direction (rightward) of the bolt 31, the terminals 7R, 7L can be moved closer to the rear side of the bolt 31 to insert the bolt 31 into the notches 74R, 74L.

[0028] The present invention is not limited to the above-described embodiments, and can be appropriately modified, improved, etc. Furthermore, the material, shape, size, 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.

[0029] According to the above-described embodiment, the bolts 31, 31 are held so as to protrude to the right from the bolt holding portion 4, but this is not limited thereto. The bolts 31, 31 may be held so as to protrude to the left from the bolt holding portion 4. Furthermore, the bolts 31, 31 may be held so as to protrude rearward from the bolt holding portion 4.

[0030] According to the above-described embodiment, the terminals 7R, 7L are provided with the connecting portions 72R, 72L and are bent into a substantially L-shape when viewed from above, but this is not limiting. The terminals 7R, 7L may be provided with a bolt connection portion provided with a through-hole for the bolt 31 and an electric wire connection portion, as in a normal LA terminal, and fastened with the bolt so that the electric wire connection portion faces forward.

[0031] In the above-described embodiment, the bolt connection portions 71R, 71L of the terminals 7R, 7L are provided with the notches 74R, 74L, but this is not limiting. If there is space to the right of the bolt 31, the bolt connection portions 71R, 71L may be provided with a through-hole that passes through the bolt 31. In this case, the terminals 7R, 7L are brought close to the right side of the bolt 31, and the bolt 31 is passed through the through-hole.
