It is formed in a substantially U shape (or a substantially U shape) smaller than the water rib 61q. Here, the second lower-side water blocking rib 61r has a distal end bent to a side wall surface 61e in the depth direction. The first lower water stop rib 61q and the second lower water stop rib 61r are connected to each other at both ends of a substantially U-shape (or a substantially U-shape) to form a closed end.

  Therefore, in the electrical junction box 1, the first upper side water stop rib 7k, the second upper side water stop rib 7l and the first lower side water stop rib 61q provided in the vicinity of the vertical overlapping portion 10 are arranged in the depth direction. The first maze-like structure that overlaps and overlaps is formed, and the second upper side water stop rib 7l, the third upper side water stop rib 7m, and the second lower side water stop rib 61r overlap each other in the depth direction. A complex maze-like second maze is formed. As a result, the electrical junction box 1 suppresses water from entering the housing space 62 side from the outside through the gap between the second lid portion 7b of the upper cover 7 and the upper wall surface 61a of the lower cover 6. .

  Here, the first partition wall 61s formed in the main body 61 of the lower cover 6 partitions the drainage passage 61t on the upper side in the vertical direction of the housing space 62 as shown in FIGS. . The first partition wall 61s is formed in a rectangular plate shape. The first partition wall 61s is formed on the lower side of the upper wall surface 61a with respect to the height direction at a predetermined interval from the upper wall surface 61a. The first partition wall 61s is formed to extend between the second opening 64 and the side wall surface 61e in the depth direction. The drainage passage 61t is partitioned through the first partition wall 61s on the upper side in the vertical direction of the accommodation space 62. As shown in FIGS. 1, 10, 11 and the like, the drainage passage 61t has one end in the depth direction communicating with the gap between the first lower water stop rib 61q and the second lower water stop rib 61r, and the other end. Opens to the outside of the main body 61, here in the side wall surface 61e in the depth direction. Accordingly, the drainage passage 61t functions as a flow path for discharging water that has entered the second opening 64 from the first lower water blocking rib 61q to the outside of the main body 61. Here, the drainage passage 61t is divided into three passages by reinforcing ribs 61u (see FIG. 11) formed along the depth direction between the upper wall surface 61a and the first partition wall 61s, but is not limited thereto. Absent.

  As described above, the drain passage 61t is partitioned by the upper wall surface 61a that is the upper wall surface of the main body 61 in the vertical direction and the first partition wall 61s, and extends along the horizontal direction. And the main-body part 61 of this embodiment has the return recessed part 61t 'formed in the vertical direction lower side on both sides of the 1st partition wall 61s in the opening of the exterior side of the drainage channel 61t, as shown in FIG. Thus, the splash of water from the outside side is prevented from entering the opening of the drainage passage 61t.

  Further, here, the third upper-side water blocking rib 7m is formed at a position slightly deviated from the vertical overlapping portion 10 as described above, and is thereby exposed in the accommodation space portion 62. And the 3rd upper side water stop rib 7m is formed so that a vertical direction lower end part may be located in the perpendicular direction upper side of the dripping allowable position removed from electronic component 4 of electronic component unit 2 stored in storage space part 62. The Here, the third upper-side water blocking rib 7 m is positioned at the upper side in the vertical direction between the fuse 41 as the electronic component 4 and the relay 42 as the electronic component 4 at the lower end in the vertical direction. That is, here, the dripping allowable position that is removed from the electronic component 4 is a position between the fuse 41 and the relay 42. Thereby, even if the electrical junction box 1 is a case where water intrudes into the accommodation space 62 side beyond the second lower-side water blocking rib 61r, the dripping position of the invading water from the electronic component 4 can be changed. It is possible to control to the dropping allowable position.

  Further, as shown in FIGS. 3, 9, 12, and the like, the electrical connection box 1 has an upper cover 7 and a lower cover 6 that have a horizontal overlapping portion 11, and in the vicinity of the horizontal overlapping portion 11, A fourth upper water stop rib 7n as a four lid member side rib, a first guide passage 7o, and the like are provided.

  The horizontal overlapping portion 11 is configured such that, in the upper cover 7 and the lower cover 6, the upper cover 7 extends along the edge along the vertical direction of the first opening 63 in a state where the upper cover 7 is assembled to the lower cover 6. This is a portion that is located outside 61 and overlaps in the horizontal direction. Here, in the horizontal overlapping portion 11, the side wall surfaces 7 c and 7 d of the upper cover 7 and the side wall surfaces 61 c and 61 d of the lower cover 6 overlap each other along the edge of the first opening 63 along the vertical direction. Thus, a pair is formed linearly on both sides in the width direction of the electrical junction box 1. The lower side guide portions 61j and 61k and the upper side guide portions 7e and 7f described above also constitute a part of the horizontal overlapping portion 11.

  The 4th upper side water stop rib 7n is provided in each horizontal direction overlap part 11, respectively. Each of the fourth upper-side water blocking ribs 7n is formed in the vicinity of the side wall surfaces 61c and 61d on the inner surface in the depth direction of the first lid portion 7a of the upper cover 7, that is, the surface facing the accommodating space 62. The Each of the fourth upper-side water blocking ribs 7n is located on the housing space 62 side of the main body 61 in each horizontal overlapping portion 11 in a state where the upper cover 7 is assembled to the main body 61 of the lower cover 6 and is in the closed position. The first opening 63 extends along the edge along the vertical direction. Each fourth upper-side water blocking rib 7n protrudes from the inner surface in the depth direction of the first lid portion 7a to the side wall surface 61e in the depth direction and extends in the height direction in each horizontal overlapping portion 11. Each 4th upper side water blocking rib 7n is comprised so that it may overlap with the side wall surfaces 61c and 61d and the side wall surfaces 7c and 7d in the width direction. Here, as shown in FIG. 12, the lower cover 6 and the upper cover 7 are configured such that, in one horizontal overlapping portion 11, the side wall surface 7 c and the side from the outside toward the accommodation space 62 side with respect to the width direction. The wall surface 61c and the fourth upper water stop rib 7n overlap in this order. Similarly, the lower cover 6 and the upper cover 7 are the side wall surface 7d, the side wall surface 61d, and the fourth upper side from the outside toward the housing space 62 side in the width direction in the other horizontal overlapping portion 11. It overlaps in order of the water stop rib 7n. As a result, in the electrical junction box 1, the fourth upper water blocking ribs 7 n, the side wall surfaces 7 c and 7 d, and the side wall surfaces 61 c and 61 d are staggered in the horizontal overlapping portion 11 between the lower cover 6 and the upper cover 7. A maze-like structure is formed, and water is prevented from entering the housing space 62 side from the outside through a gap between the side wall surfaces 7c and 7d and the side wall surfaces 61c and 61d.

  The first guide passages 7o are respectively formed in the horizontal overlapping portions 11. Each first guide passage 7o has the above-described fourth upper-side water-stopping ribs 7n on the side in the horizontal direction of the housing space 62 in a state where the upper cover 7 is assembled to the main body 61 of the lower cover 6 and is in the closed position. This is a flow path that guides water that has entered the housing space 62 side through the gap between the side wall surfaces 7c, 7d and the side wall surfaces 61c, 61d of the horizontal overlapping portion 11 in the vertical direction. Each first guide passage 7o is partitioned by each fourth upper water blocking rib 7n and the side wall surfaces 61c and 61d and extends in the height direction. As a result, the electrical junction box 1 has intruded even if water has entered the housing space 62 side from the outside through the gap between the side wall surfaces 7c and 7d and the side wall surfaces 61c and 61d. By guiding the water downward in the vertical direction, the invading water is prevented from moving and adhering to the electronic component unit 2 side accommodated in the accommodation space 62.

  In addition, as shown in FIG. 12, the electrical junction box 1 further includes ribs 61v and ribs so as to sandwich the holding plate-like portion 52 of the block 5 in the width direction in the vicinity of the side wall surfaces 61c and 61d of the main body 61. 61w is formed. Each rib 61v and each rib 61w extend along the depth direction. Each 4th upper side water stop rib 7n is located between each rib 61v and each rib 61w with respect to the width direction, and each rib 61w of each 4th upper side water stop rib 7n with respect to the depth direction It extends to the vicinity. Thus, in the electrical junction box 1, the ribs 61v and the ribs 61w and the fourth upper water stop ribs 7n cooperate with each other so that the gaps between the side wall surfaces 7c and 7d and the side wall surfaces 61c and 61d are eliminated. Even when water enters from the outside to the accommodation space 62 side, the intruded water is prevented from wrapping around and adhering to the electronic component unit 2 side accommodated in the accommodation space 62.

  Furthermore, as shown in FIGS. 1, 2, and 4, in the electrical junction box 1, the main body portion 61 of the lower cover 6 includes a second partition wall 61 x and a second guide passage 61 y. The second partition wall 61x and the second guide passage 61y are provided on both sides of the main body 61 in the width direction. Each of the second partition walls 61x and each of the second guide passages 61y are formed on the upper side in the height direction from the portion where the electronic component unit 2 is held. Each of the second partition walls 61x partitions each of the second guide passages 61y on the lateral side of the accommodation space 62. Each second partition wall 61x is formed in a rectangular plate shape. Each of the second partition walls 61x is formed on the inner side of each of the side wall surfaces 61c and 61d (that is, the accommodation space portion 62 side) with respect to the width direction with a predetermined distance from each of the side wall surfaces 61c and 61d. Each second partition wall 61x is formed to extend in the depth direction and the height direction. Each of the second guide passages 61y is partitioned through the second partition walls 61x on the side in the horizontal direction of the accommodation space 62. More specifically, each second guide passage 61y is partitioned by each second partition wall 61x and each side wall surface 61c, 61d. Each of the second guide passages 61y functions as a flow path that guides water that has entered the storage space 62 side between the second opening 64 and the upper cover 7 downward in the vertical direction. Thereby, even if the electrical junction box 1 is a case where water infiltrates from the outside side to the accommodation space part 62 side between the 2nd opening part 64 and the upper cover 7, the said water which penetrate | invaded By guiding to the lower side in the vertical direction, the invaded water is prevented from moving and adhering to the electronic component unit 2 side accommodated in the accommodation space 62.

  The water guided downward in the vertical direction through the first guide passages 7o, the second guide passages 61y, etc. falls on the lower side wall surface 61b by its own weight, for example, and is formed on the lower side wall surface 61b. It is discharged to the outside of the main body 61 through the inserted opening 61g and the like.

  In the electrical junction box 1 configured as described above, the electronic component unit 2 is configured by assembling the electronic component 4 to the block 5, and the electronic component unit 2 is accommodated in the lower cover 6 through the first opening 63. Inserted into the part 62. At this time, the electronic component unit 2 is slid and inserted along the depth direction so that each holding plate-like portion 52 of the block 5 is inserted into each receiving portion 61f from the first opening 63, and is accommodated by each receiving portion 61f. It is held in the space 62. And after connecting the electric wire extended from the height direction lower side of the electronic component unit 2 to the insertion port 61g, the semi-cylindrical part division body 61i is assembled | attached to the electrical junction box 1. As shown in FIG. As described above, the electric connection box 1 has a rattling with respect to the vertical direction (height direction) because the holding plate-like portions 52 of the electronic component unit 2 are sandwiched and held by the receiving portions 61f in the height direction. It can be set as the structure which is easy to reduce. For example, when the electrical junction box 1 is mounted on a vehicle, the vibration along the vertical direction tends to be relatively large. However, as described above, the electrical connection box 1 can be configured to easily reduce the backlash in the vertical direction. The electronic component unit 2 can be properly held.

  The electrical connection box 1 is configured such that the front end portions of the lower side guide portions 61j and 61k of the lower cover 6 are inserted into the openings at the lower ends of the upper side guide portions 7e and 7f of the upper cover 7 in the height direction. Is assembled to the lower cover 6. The upper cover 7 can be slid to the open position and the closed position along the height direction while the upper side guide portions 7e and 7f are guided by the lower side guide portions 61j and 61k. In the electrical junction box 1, the first opening 63 and the second opening 64 are closed in a state where the upper cover 7 is located at the closed position, and the housing space 62 for housing the electronic component unit 2 is open to the outside. It becomes a closed space. On the other hand, the electrical connection box 1 visually observes the fuse 41 as the electronic component 4 assembled to the cavity 51 through the second opening 64 from the upper side in the height direction with the upper cover 7 positioned at the open position. The fuse 41 can be operated, and for example, the fuse 41 can be replaced through the second opening 64. That is, in the electrical junction box 1, as described above, the sliding direction of the upper cover 7 and the insertion direction of the electronic component unit 2 through the first opening 63 are orthogonal, and the sliding direction of the upper cover 7 and the block 5 are The attachment / detachment direction of the electronic component 4 coincides.

  According to the electric junction box 1 described above, the electronic component unit 2 in which the electronic component 4 is assembled to the block 5, the body portion 61 formed in a hollow shape, and the electronic component unit 2 formed inside the body portion 61 A housing space 62 to be housed, a first opening formed in the main body portion 61 that allows the outside of the main body portion 61 to communicate with the housing space portion 62 so that the electronic component unit 2 can be inserted into the housing space portion 62 along the depth direction. The electronic component 4 assembled to the block 5 in a state in which the electronic component unit 2 is accommodated in the accommodating space portion 62, formed in the portion 63 and the main body portion 61, and communicating with the outside of the main body portion 61 and the accommodating space portion 62. And a lower cover 6 having a second opening 64 facing along the height direction intersecting the depth direction, the first opening 63 and the first cover 63 by being assembled to the main body 61 and moving along the height direction. 2 And a upper cover 7 can be opened and closed the mouth 64.

  Therefore, in the electrical junction box 1, the electronic component unit 2 in which the electronic component 4 is assembled to the block 5 can be inserted into the accommodation space 62 along the depth direction through the first opening 63, while the block 5 Work can be performed on the electronic component 4 through the second opening 64 facing the electronic component 4 assembled in the height direction along the height direction. And the electrical junction box 1 can open and close the 1st opening part 63 and the 2nd opening part 64 because the upper cover 7 moves along a height direction, ie, the opening-and-closing track of the upper cover 7 Can be a linear track along the height direction, the space required to open and close the upper cover 7 can be made relatively small. As a result, the electrical connection box 1 can be used for the electronic component 4 accommodated therein even when it is difficult to secure a space for opening and closing the upper cover 7 around the electrical connection box 1, for example. Can work properly. Thereby, the electrical junction box 1 can perform replacement | exchange etc. of the electronic component 4 easily, for example, and can improve the workability | operativity at the time of a maintenance.

  In the electrical junction box 1, the electronic component unit 2 is inserted into the accommodation space 62 along the depth direction via the first opening 63, and the upper cover 7 intersects the insertion direction of the electronic component unit 2. Since it is configured to open and close by moving in the direction, for example, the occurrence of biting of the electric wire when the upper cover 7 is opened and closed can be suppressed.
