Thereby, in the locking mechanisms 10R and 10L, the first protrusion main body portion 84 is directed upward with respect to the first receiver main body portion 33, and the second protrusion main body portion 85 is directed upward with respect to the second receiver main body portion 34. In addition, the two guide projections 86 can be moved upward with respect to the two guide portions 35, and the locking of the adjacent block 8 to the box body 3 is released. Next, the worker pulls out the adjacent block 8 from the second opening 3c to the outside of the box body 3 in a state where the locking by the locking mechanisms 10R and 10L is released, and as shown in FIG. 8 is removed from the housing 2 by positioning it outside the housing 2. At this time, in the restriction mechanisms 11R and 11L, the restriction projections 87R and 87L are removed from the upper direction with respect to the restriction receiving parts 74R and 74L, and the target block 7 can be moved to the non-overlapping region S2 by the slide mechanisms 9R and 9L. It becomes a state. Next, the worker moves the target block 7 located in the overlapping area S1 to the non-overlapping area S2 by the slide mechanisms 9R and 9L as shown in FIG. At this time, in the slide mechanisms 9R and 9L, the slide protrusions 31R and 31L come out from the near side with respect to the slide receiving portions 73R and 73L, and the guidance of the target block 7 is finished in the non-overlapping region S2. As a result, the target block 7 is not restricted in any direction in the non-overlapping region S2. Next, the worker pulls out the target block 7 from the second opening 3c to the outside of the box body 3 in a state where the guidance by the slide mechanisms 9R and 9L is completed, and as shown in FIG. It is removed from the housing 2 by being positioned outside the body 2. As a result, the target electronic component 72 to be replaced can be replaced for each target block 7 or for each electronic component. As shown in FIG. 7, the worker positions the replaced target block 7 on the lower side of the box body 3. Next, the worker inserts the replaced target block 7 into the internal space 3a of the box body 3 through the second opening 3c, and places the replaced target block 7 in the non-overlapping area S2 as shown in FIG. Position. Next, the worker moves the replaced target block 7 from the non-overlapping area S2 to the overlapping area S1 by the slide mechanisms 9R and 9L as shown in FIG. Next, the worker positions the adjacent block 8 on the upper side of the box body 3. Next, the worker inserts the adjacent block 8 into the internal space 3a of the box body 3 through the second opening 3c, and positions the adjacent block 8 in the non-overlapping region S2, as shown in FIG. At this time, in the locking mechanisms 10R and 10L, first, the two guide protrusions 86 are inserted into the two guide parts 35 from above, and then the second protrusion main body part 85 is Further, the first receiving main body portion 33 gets over the first protrusion main body portion 84, and the first protrusion main body portion 84 is inserted into the first receiving main body portion 33. Further, in the regulation mechanisms 11R and 11L, the regulation projections 87R and 87L are inserted from above with respect to the regulation receivers 74R and 74L. Thereby, the adjacent block 8 is locked in the attaching / detaching direction with respect to the box body 3 by the locking mechanisms 10R and 10L, and is disposed in the non-overlapping region S2. Further, the target block 7 is connected to the adjacent block 8 by the restriction mechanisms 11R and 11L, and is arranged in the overlapping region S1. Next, as shown in FIG. 1, the worker locks the second upper cover 6 with respect to the box body 3 by the locking mechanism R3.

  As described above, the electrical junction box 1 according to the present embodiment suppresses the gap between the housing 2 and the vehicle component 200 because the housing 2 overlaps the vehicle component 200 in the attaching / detaching direction in the overlapping region S1. be able to. Moreover, since the target block 7 (target electronic component 72) can be arranged in the overlapping area S1, it is possible to suppress the formation of a useless space in the overlapping area S1 in the internal space portion of the housing 2. . Further, the second upper cover 6 can be removed, the target block 7 (target electronic component 72) can be removed from the housing 2 through the second opening 3c, and can be disposed again in the internal space of the housing 2. Accordingly, the target block 7 (target electronic component 72) can be replaced, and the vehicle interior space 300 can be effectively used.

  Moreover, since the adjacent block 8 (adjacent electronic component 82) can regulate the movement of the target block 7 (target electronic component 72) located in the overlapping region S1 in the sliding direction, the target in the internal space portion of the housing 2 can be controlled. The positioning of the block 7 (target electronic component 72) can be ensured. Further, the second upper cover 6 can be removed, the adjacent block 8 (adjacent electronic component 82) can be removed from the housing 2 through the second opening 3c, and can be disposed again in the internal space of the housing 2. As a result, the adjacent block 8 (adjacent electronic component 82) can be replaced, and the vehicle interior space 300 can be effectively utilized.

  In addition, since the target electronic component 72 is handled in units of the target block 7, the time required for replacing the target electronic component 72 can be shortened as compared with the case where a plurality of target electronic components 72 are handled individually.

  Since the wire harness 100 described above includes the electrical junction box 1, the target block 7 (target electronic component 72) can be replaced, and the vehicle interior space 300 can be effectively used.

  In addition, although the electrical junction box 1 which concerns on the said embodiment made one object block 7 arrange | positioned in duplication area | region S1, it is not limited to this, A plurality may be sufficient. In this case, the plurality of target blocks 7 are preferably arranged in parallel in the sliding direction with respect to the box body 3. Thereby, when exchanging the target block 7 close | similar in the slide direction with respect to the adjacent block 8, the target block 7 located in the back | inner direction rather than the target block 7 used as the exchange object is the target block 7 used as the exchange target It can suppress that it removes.

  Further, an urging means may be provided between the target block 7 and the box body 3 in the sliding direction. For example, the biasing means is attached to the inner wall surface in the back direction of the box body 3 so as to face the side surface in the back direction of the block body 71, and the target block 7 is disposed in the overlapping region S1, A biasing force in the front direction is applied to the target block 7 against the box body 3. As a result, it becomes easy to move the target block 7 located in the overlapping area S1 to the non-overlapping area S2 by the urging force of the urging means, and therefore workability in the replacement work of the target block 7 (target electronic component 72). Can be improved.

  Note that the electrical junction box 1 according to the present embodiment is provided in the vehicle interior space 300 such that a part of the housing 2 on the back side in the sliding direction overlaps the protruding portion 201 of the vehicle component 200 in the attachment / detachment direction. Although it is accommodated, it is not limited to this. For example, the electrical junction box 1 becomes a second region closer to the worker who replaces the target block 7 (target electronic component 72) of the electrical junction box 1 in the vehicle interior space 300, and a first region farther away. You may accommodate. In other words, the second region may be the side where workers can easily reach, and the first region may be the side difficult to reach. In this case, the first region may not overlap the protrusion 201 in the attaching / detaching direction.
