[0010] [Embodiment] FIG. 1 is a perspective view of a wire harness WH to which an electric junction box 1 according to an embodiment is applied in a first usage form P1, and FIG. 2 is a perspective view of the wire harness WH in a second usage form P2. The electric junction box 1 of the present embodiment shown in FIGS. 1 and 2 is incorporated into a wire harness WH that is wired in a vehicle such as an automobile. Here, the wire harness WH is, for example, a bundle of wiring materials W used for power supply and signal communication for connection between each device mounted on a vehicle, and the wiring materials W are connected to each device by connectors or the like. The wire harness WH of the present embodiment includes, for example, a wiring material W having conductivity and an electric junction box 1 electrically connected to a terminal of the wiring material W. In addition, the wire harness WH may be configured to include various components such as grommets, protectors, fixtures, and connectors.

[0011] In the following description, among the first, second, and third directions intersecting each other, the first direction is referred to as the "extension direction X", the second direction is referred to as the "width direction Y", and the third direction is referred to as the "height direction Z". Here, the extension direction X, the width direction Y, and the height direction Z are approximately perpendicular to each other. The extension direction X typically runs along the depth direction (front-rear direction) of the electric junction box 1, the extension direction (longitudinal direction) of the first block 20 and the second block 30 of the electric junction box 1 described later, and the like. The width direction Y typically runs along the width direction (left-right direction) of the electric junction box 1, the width direction of the first block 20 and the second block 30, and the like. The height direction Z typically runs along the height direction (up-down direction) of the electric junction box 1, the height direction of the first block 20 and the second block 30, and the like. In addition, each direction used in the following description will be described as a direction in a state in which the electric junction box 1 is assembled to a vehicle, unless otherwise specified.

[0012] The wiring material W is configured to include, for example, a wire bundle in which a plurality of electric wires are bundled together, and a corrugated tube as a cylindrical exterior material that covers the wire bundle. The wiring material W has relatively high flexibility and good bendability in an attached state in which the corrugated tube is attached to the wire bundle. The wiring material W of this embodiment is covered by a side cover 60, and is attached to the electrical connection box 1 in a state where it is integrated with the side cover 60. The side cover 60 protects the wiring material W inserted inside the side cover 60, and regulates the wiring path of the wiring material W.

[0013] The electrical connection box 1 includes, for example, a housing 10, a first block 20, and a second block 30. The housing 10 accommodates the first block 20 and the second block 30 therein, and is formed of an insulating synthetic resin material or the like. The housing 10 includes, for example, a frame 11 having an accommodation space 12, an upper cover that covers the accommodation space 12 of the frame 11 from one side in the height direction Z, a lower cover that covers the accommodation space 12 of the frame 11 from the other side in the height direction Z, and a pair of lid members 15 (described later) that openably and closably cover a pair of notches 11f formed in the frame 11.

[0014] The first block 20 is, for example, an electronic component unit on which a plurality of electronic components 21 are mounted, and is accommodated in the accommodation space 12 of the housing 10. The first block 20 is provided with a plurality of openings that are open toward one side in the height direction Z and into which the electronic components 21 are inserted. The electronic components 21 are, for example, fuses, relays, etc. The electrical connection box 1 is what is called a relay box, junction box, etc., and is, for example, attached to a load unit provided in a vehicle, and is capable of passing or cutting off a current flowing through the load unit.

[0015] The second block 30 is, for example, a connection unit provided with a terminal connection portion 31 that is electrically connected to the electronic component 21 of the first block 20 and is electrically connected to a terminal 40 provided at the end of the wiring material W, and is accommodated in the accommodation space portion 12 of the housing 10. In this embodiment, the second block 30 is provided with the above-mentioned terminal connection portion 31 at one end in the extension direction X, while the second block 30 is provided with a component mounting portion 32 at the other end in the extension direction X on which components 50 related to the electronic component 21 are mounted. The component mounting portion 32 is formed with a plurality of openings that are open toward one side in the height direction Z and into which the components 50 related to the electronic component 21 are inserted. The components 50 related to the electronic component 21 are, for example, spare fuses for replacement, relays, and the like, as well as pullers and the like as attachment and detachment tools used when removing fuses.

[0016] In such a configuration, the wire harness WH of the present embodiment is configured to be usable in at least two usage forms, a first usage form P1 (see FIG. 1) and a second usage form P2 (see FIG. 2), depending on the specifications of the vehicle to which it is applied. That is, in the first usage form P1 according to the specifications of the vehicle to which it is applied, the second block 30 is installed with respect to the first block 20 in a state in which the terminal connection portion 31 is located at one end of the extension direction X and the component mounting portion 32 is located at the other end of the extension direction X. In this case, the housing 10 is used in a state in which one cover member 15 separated from the terminal connection portion 31 closes the notch portion 11f and the other cover member 15 adjacent to the terminal connection portion 31 opens the notch portion 11f. Then, the side cover 60 is attached so as to cover the other notch portion 11f adjacent to the terminal connection portion 31, and the terminal 40 provided at the end of the wiring material W is electrically connected to the terminal connection portion 31.

[0017] On the other hand, in the wire harness WH of the present embodiment, in a second usage form P2 according to the specifications of the vehicle to which it is applied, the second block 30 is installed in a state inverted with respect to the first block 20 from the first usage form P1 in which the component mounting portion 32 is located at one end in the extension direction X and the terminal connection portion 31 is located at the other end in the extension direction X. In this case, the housing 10 is used in a state in which the other cover member 15 separated from the terminal connection portion 31 closes the notch portion 11f and one cover member 15 adjacent to the terminal connection portion 31 opens the notch portion 11f. Then, the side cover 60 is attached so as to cover one cutout portion 11f adjacent to the terminal connection portion 31, and the terminal 40 provided at the end of the wiring material W is electrically connected to the terminal connection portion 31.

[0018] FIG. 3 is a plan view of the wire harness WH to which the electric connection box 1 according to the embodiment is applied in a first usage form P1, and FIG. 4 is a plan view of the wire harness WH according to the embodiment in a second usage form P2. As shown in FIGS. 3 and 4, the frame 11 of the housing 10 is formed, for example, in a substantially rectangular box shape with the extension direction X being the long side direction. The frame 11 has a plurality of walls such as a bottom wall 11a, a pair of first side walls 11b, 11d, and a pair of second side walls 11c, 11e. The bottom wall 11a, the pair of first side walls 11b, 11d, and the pair of second side walls 11c, 11e are structures for partitioning the housing space 12 of the housing 10. The housing space 12 is a space in which the first block 20 and the second block 30 are accommodated.

[0019] The lower wall 11a extends along a direction perpendicular to the height direction Z and constitutes the lower end of the frame 11. The pair of first side walls 11b, 11d each extend along a direction perpendicular to the extension direction X and are provided parallel to each other with a gap in the extension direction X. One of the first side walls 11b, 11d, the first side wall 11b, is connected to one end of the lower wall 11a in the extension direction X and constitutes the front end of the frame 11. The other of the first side walls 11b, 11d, the first side wall 11d, is connected to the other end of the lower wall 11a in the extension direction X and constitutes the rear end of the frame 11. The pair of second side walls 11c, 11e each extend along a direction perpendicular to the width direction Y and are provided parallel to each other with a gap in the width direction Y. The second side wall 11c of the second side walls 11c, 11e is connected to one end of the bottom wall 11a in the width direction Y and constitutes the left end of the frame 11. The other second side wall 11e of the second side walls 11c, 11e is connected to the other end of the bottom wall 11a in the width direction Y and constitutes the right end of the frame 11.

[0020] Further, the first side wall 11b is provided with a first cutout portion 11f1 (see FIG. 8) constituting one of the pair of cutout portions 11f described above. The first cutout portion 11f1 is provided at one end (upper end) of the first side wall 11b in the height direction Z, and penetrates the first side wall 11b along the extension direction X. The first cutout portion 11f1 is formed so as to expose the terminal connection portion 31 at the first position when the terminal connection portion 31 is attached to the first block 20 at the first position in the first usage form P1. That is, the first cutout portion 11f1 is provided at a position close to the terminal connection portion 31 at the first position when the terminal connection portion 31 is attached to the first block 20 at the first position. The first cutout portion 11f1 is covered by the first cover member 15A constituting one of the pair of cover members 15 described above in an openable and closable manner.

[0021] Further, the second side wall 11e is provided with a second cutout 11f2 (see FIG. 9) constituting the other of the pair of cutouts 11f described above. The second cutout 11f2 is provided at one end (upper end) of the second side wall 11e in the height direction Z, and penetrates the second side wall 11e along the width direction Y. The second cutout 11f2 is formed so as to expose the terminal connection part 31 at the second position when the terminal connection part 31 is attached to the first block 20 at the second position in the second usage form P2 (see FIG. 4). That is, the second cutout 11f2 is provided at a position close to the terminal connection part 31 at the second position when the terminal connection part 31 is attached to the first block 20 at the second position. The second cutout 11f2 is covered by the second cover member 15B constituting the other of the pair of cover members 15 described above in an openable and closable manner.

[0022] Fig. 5 is an exploded perspective view of the first block 20 and the second block 30 of the electric junction box 1, Fig. 6 is a perspective view of the first block 20 and the second block 30 in a first usage configuration P1, and Fig. 7 is a perspective view of the first block 20 and the second block 30 in a second usage configuration P2. As shown in Figs. 5 to 7, the first block 20 includes, for example, a first block body 20b, a plurality of electronic components 21, a first bus bar 22, and a stud bolt 23.

[0023] The first block body 20b is formed, for example, in a substantially rectangular parallelepiped shape with the extension direction X being the long side direction. The first block body 20b is provided with a plurality of openings 20a that are open toward one side in the height direction Z and into which the electronic components 21 are inserted. The plurality of openings 20a are arranged at intervals from each other in the extension direction X and the width direction Y in the first block body 20b. The first block body 20b is also provided with a protrusion 20c that protrudes from a substantial center portion in the extension direction X toward the other side in the width direction Y (the second block 30 side).

[0024] The first bus bar 22 includes, for example, one end provided in the multiple openings 20a and electrically connected to each of the electronic components 21, the other end provided exposed on the tip surface of the protrusion 20c, and an intermediate portion connecting the one end and the other end. The first bus bar 22 is a conductive member for electrically connecting the multiple electronic components 21 and the terminal connection portion 31 together with the second bus bar 33 on the second block 30 side. The stud bolt 23 is provided at the other end of the first bus bar 22 and protrudes toward the second block 30 along the width direction Y. The stud bolt 23 is, for example, engaged with an engagement groove portion formed in the first bus bar 22 in the width direction Y and is electrically connected to the first bus bar 22.

[0025] The second block 30 includes, for example, a second block body 30a, a terminal connection portion 31, a component mounting portion 32, and a second bus bar 33. The second block body 30a is formed, for example, in a substantially rectangular parallelepiped shape with the extension direction X being the long side direction. The second block body 30a is provided with the terminal connection portion 31 at one end in the extension direction X, and with the component mounting portion 32 at the other end in the extension direction X. In addition, a slit is formed in the substantially central portion between the terminal connection portion 31 and the component mounting portion 32 of the second block body 30a, which extends along the extension direction X and engages with the other end of the second bus bar 33.

[0026] The second bus bar 33 includes, for example, one end electrically connected to the terminal connection portion 31, the other end provided with an opening 33a through which the stud bolt 23 is inserted in the width direction Y, and an intermediate portion connecting the one end and the other end. The opening 33a is provided in a substantially central portion between the terminal connection portion 31 and the component mounting portion 32 of the second block 30 in the extension direction X. The terminal connection portion 31 is provided at one end of the second bus bar 33 and protrudes upward along the height direction Z. The terminal connection portion 31 is, for example, a stud bolt or the like, and is engaged with an engagement hole portion formed in the second bus bar 33 in the height direction Z and is electrically connected to the second bus bar 33.

[0027] The component mounting section 32 is a space in which the components 50 related to the electronic component 21 are mounted. The component mounting section 32 is formed with a plurality of openings 32a that are open toward one side in the height direction Z, for example, and into which the components 50 related to the electronic component 21 are inserted. The components 50 related to the electronic component 21 are, for example, spare fuses for replacement, relays, and pullers as attachment / detachment tools used when removing fuses. In this way, in this embodiment, by installing the components 50 related to the electronic component 21 in the component mounting section 32, the replacement work of the electronic component 21 can be performed more easily, more smoothly, or more quickly.

[0028] In this embodiment, the second block 30 can be electrically connected to the electronic component 21 in each of the first usage form P1 (see FIG. 6) and the second usage form P2 (see FIG. 7) by fastening the first block 20 together with the nut 70 with the stud bolt 23 inserted through the opening 33a. At this time, in this embodiment, the opening 33a is provided in the center between the terminal connection portion 31 and the component mounting portion 32 of the second block 30 in the extension direction X, so that the space in the center of the first block 20 and the second block 30 in the extension direction X can be effectively used to provide a fastening structure between the stud bolt 23, the opening 33a, and the nut 70.

[0029] Fig. 8 is an exploded perspective view of the wire harness WH to which the electric junction box 1 is applied, in which the second cover member 15B is positioned in the closed position P3, and Fig. 9 is an exploded perspective view of the wire harness WH to which the electric junction box 1 is applied, in which the second cover member 15B is positioned in the open position P4. As shown in Figs. 8 and 9, in this embodiment, the first cover member 15A is supported rotatably between the closed position P3 and the open position P4 via the hinge 19 relative to the first side wall 11b, and the second cover member 15B is supported rotatably between the closed position P3 and the open position P4 via the hinge 19 relative to the second side wall 11e. The hinge 19 of the first cover member 15A has a rotation center extending along the width direction Y, and the hinge 19 of the second cover member 15B has a rotation center extending along the extension direction X.

[0030] The housing 10 also has a first locking portion 16 (see FIG. 9) that locks the second cover member 15B in the closed position P3, and a second locking portion 17 that locks the second cover member 15B in the open position P4. The first locking portion 16 includes, for example, a pair of claws 16a provided on the inner surface of the second cover member 15B, and a locked portion (see FIG. 3) provided on the periphery of the second cutout portion 11f2 in the second side wall 11e. The pair of claws 16a have locking surfaces that face the locked portions in the width direction Y, and the locking surfaces and the locked portions are locked to restrict movement (rotation) of the second cover member 15B from the closed position P3 to the open position P4 relative to the second side wall 11e.

[0031] The second locking portion 17 includes, for example, an engagement protrusion 17a provided on the outer surface of the second side wall 11e, and a slit 17b provided on the second cover member 15B and engaged with the engagement protrusion 17a. The engagement protrusion 17a is provided with a groove 17a1 facing the upper end of the slit 17b, and the groove 17a1 and the upper end of the slit 17b are engaged with each other, so that the second cover member 15B is locked in an inclined position relative to the second side wall 11e in the open position P4. Specifically, the second cover member 15B is inclined toward the other side in the width direction Y as it approaches the other side (lower side) in the height direction Z in the open position P4. This allows the second cover member 15B to function as, for example, a splash prevention member for water or the like.

[0032] In this embodiment, the housing 10 has a first locking portion 16 that locks the first cover member 15A in the closed position P3, and a second locking portion 17 that locks the first cover member 15A in the open position P4. The first locking portion 16 is configured to include a pair of claw portions 16a and a locked portion similar to the first locking portion 16 on the second cover member 15B side, and the second locking portion 17 is configured to include an engagement projection 17a and a slit 17b similar to the second locking portion 17 on the second cover member 15B side.

[0033] In this embodiment, an opening 60a is provided at the tip of the side cover 60, penetrating in the extension direction X. A terminal 40 provided at the end of the wiring material W is inserted into the opening 60a, and the terminal 40 is engaged with the peripheral portion of the opening 60a, thereby restricting the movement (detachment) of the terminal 40 and the wiring material W in the extension direction X relative to the side cover 60. In addition, the wiring material W is fixed to the first cover member 15A or the second cover member 15B positioned in the open position P4 by wrapping tape or the like in a state in which the side cover 60 is attached so as to cover the first notch 11f1 of the first side wall 11b or the second notch 11f2 of the second side wall 11e. The terminal 40 is configured by a so-called round terminal (LA terminal) or the like.

[0034] As described above, in the electric junction box 1 and the wire harness WH of the present embodiment, the second block 30 is configured to be able to be installed in the housing space 12 in a state electrically connected to the electronic component 21 in at least two usage configurations: a first usage configuration P1 in which the terminal connection portion 31 is located at one end in the extension direction X and the component mounting portion 32 is located at the other end in the extension direction X with respect to the first block 20; and a second usage configuration P2 in which the component mounting portion 32 is located at one end in the extension direction X and the terminal connection portion 31 is located at the other end in the extension direction X. With this configuration, the electric junction box 1 and the wire harness WH can share the first block 20 and the second block 30 among electric junction boxes 1 of a plurality of specifications in which the attachment positions of the terminal connection portion 31 with respect to the first block 20 are different, for example. As a result, the electric junction box 1 and the wire harness WH can share components.

[0035] Here, if, for example, two terminal connection parts 31 are mounted on the housing 10 to accommodate a plurality of specifications (FIGS. 3 and 4) in which the mounting positions of the terminal connection parts 31 relative to the first block 20 are different, only one of the two terminal connection parts 31 is used depending on the specifications, and there is a risk that the mounting space for the components 50 will be reduced by the space of the unused terminal connection part 31. In this regard, according to this embodiment, the component mounting part 32 is provided on the opposite side to the terminal connection parts 31 of the second block 30 in the extension direction X, and therefore, there is an advantage that the component mounting part 32 can secure space for mounting the components 50 related to the electronic components 21.

[0036] In addition, in the electrical connection box 1 and wire harness WH of this embodiment, the first block 20 has a first bus bar 22 electrically connected to the electronic component 21, and a stud bolt 23 provided at an end of the first bus bar 22 and protruding along the width direction Y, and the second block 30 has a second bus bar 33 electrically connected to the terminal connection portion 31 and provided with an opening 33a through which the stud bolt 23 is inserted in the width direction Y, and the second block 30 is electrically connected to the electronic component 21 in each of the first usage form P1 and the second usage form P2 by being tightened together with the first block 20 by a nut 70 with the stud bolt 23 inserted into the opening 33a. With this configuration, the electrical connection box 1 and the wire harness WH can be relatively easily electrically connected to the electronic component 21 in each of the first usage form P1 and the second usage form P2, which are inverted relative to each other, by, for example, the first bus bar 22 and the stud bolt 23 on the first block 20 side, and the second bus bar 33 and the nut 70 on the second block 30 side.

[0037] In the electric junction box 1 and wire harness WH of this embodiment, the opening 33a is provided in the center between the terminal connection portion 31 and the component mounting portion 32 of the second block 30 in the extension direction X, and the stud bolt 23 is provided in the center of the first block 20 in the extension direction X. With this configuration, the electric junction box 1 and wire harness WH can provide a fastening structure between the stud bolt 23, the opening 33a, and the nut 70 by effectively utilizing the space in the center of the first block 20 and the second block 30 in the extension direction X, and can thus obtain a configuration that can be electrically connected to the electronic component 21 more easily or efficiently in each of the first usage configuration P1 and the second usage configuration P2 that are inverted from each other.

[0038] In the electric junction box 1 and the wire harness WH of this embodiment, the housing 10 is configured to be usable in at least two usage configurations: a first usage configuration P1 in which the second cover member 15B closes the second cutout portion 11f2 and the first cover member 15A opens the first cutout portion 11f1, and a second usage configuration P2 in which the first cover member 15A closes the first cutout portion 11f1 and the second cover member 15B opens the second cutout portion 11f2. With this configuration, the electric junction box 1 and the wire harness WH can share the housing 10 among electric junction boxes 1 of different specifications in which, for example, the attachment position of the terminal connection portion 31 relative to the first block 20 is different.

[0039] In this embodiment, the second block 30 is configured to be able to be installed in the storage space 12 in a state electrically connected to the electronic components 21 in two usage forms, namely, the first usage form P1 and the second usage form P2, relative to the first block 20. However, this is not limited to the example, and for example, the second block 30 may be configured to be able to be installed in the storage space 12 in a state electrically connected to the electronic components 21 in three or more usage forms relative to the first block 20.

[0040] Although the embodiment of the present invention has been illustrated above, the above embodiment is merely an example and is not intended to limit the scope of the invention.
