As shown in Fig. 1, the electrical junction box 1 includes a case 2 having a first opening 21 and a second opening 22 (= openings) for inserting a wire harness (= electric wires) not shown, a base 4 housed in the case 2 and to which a bus bar 3 (= conductor) is attached, and a sealing plug 5 that closes the first opening 21 and the second opening 22.

[0012] The case 2 is formed from a conductive material such as aluminum, and includes a lower case 23 and an upper case 24 that covers the upper opening of the lower case 23. As shown in Fig. 2, the lower case 23 has a bottom wall 231 and a side wall 232 (wall) that stands upward from the entire periphery of the bottom wall 231, and is open at the top. The bottom wall 231 is provided with a positioning portion 233 that determines the position of a base 4 (described later) relative to the lower case 23. In this embodiment, two positioning portions 233 are provided (Fig. 2 shows one of the two positioning portions 233, and the other is hidden by the side wall 232).

[0013] In this embodiment, the positioning portion 233 is provided in the shape of a pin protruding upward from the bottom wall portion 231, and is inserted into a hole provided in a positioning portion 44 (see FIG. 7) of the base 4, which will be described later. One of the two positioning portions 233, not shown in FIG. 2, protrudes toward a second closing portion 52 of the sealing plug 5, which will be described later, as shown in FIG.

[0014] The side wall portion 232 is provided with a first opening 21 and a second opening 22. A wire harness is passed through each of the first opening 21 and the second opening 22. The first opening 21 and the second opening 22 penetrate the side wall portion 232 in the front-rear direction and extend to the upper end of the side wall portion 232. The first opening 21 and the second opening 22 are provided side by side in the left-right direction, independent of each other and not in communication with each other. In this embodiment, the first opening 21 and the second opening 22 are provided to have the same size and the same shape.

[0015] The upper case 24 has a top wall 241 and a side wall 242 extending downward from the entire periphery of the top wall 241, and is open on the bottom. The top wall 241 covers the upper opening of the lower case 23. The side wall 242 is placed on the outside of the side wall 232 of the lower case 23. The upper openings of the first opening 21 and the second opening 22 provided in the lower case 23 are closed by the upper case 24.

[0016] The base 4 is made of an insulating material such as synthetic resin, and has a bottom wall 41, a side wall 42 standing upward from the periphery of the bottom wall 41, and a partition wall 43 standing upright from the bottom wall 41. A bus bar 3 is disposed on the bottom wall 41 of the base 4. The bus bar 3 is connected to a wire harness inserted into the case 2 through the first opening 21 and the second opening 22. The side wall 42 of the base 4 has openings formed in positions facing the first opening 21 and the second opening 22 formed in the lower case 23 in the front-rear direction.

[0017] The bottom wall 41 of the base 4 is provided with a positioning portion 44 (see FIG. 7) that determines the position of the base 4 relative to the lower case 23, and a locking hole 45 into which a sealing plug 5, which will be described later, is locked. As shown in FIG. 7, the positioning portion 44 protrudes from the bottom wall 41 toward the bottom wall 231 of the lower case 23, and is provided with a hole into which a pin-shaped positioning portion 233 provided on the lower case 23 is inserted. As shown in FIG. 2, the locking hole 45 passes through the bottom wall 41 in the vertical direction, and is semicircular on the rear side and rectangular on the front side.

[0018] The sealing plug 5 is made of an elastic material such as rubber and closes the first opening 21 and the second opening 22 to prevent foreign matter from entering the case 2 through the first opening 21 and the second opening 22. In the manufacturing process of the electrical junction box 1, the base 4 is housed in the case 2, and the case is transported to a factory where the bus bars 3 and the wire harnesses are attached with the base 4 housed in the case 2 and the first opening 21 and the second opening 22 closed by the sealing plug 5. In the factory, the sealing plug 5 is removed, and the bus bars 3 and the wire harnesses are attached.

[0019] 3 and 4, the sealing plug 5 has a first closing portion 51, a second closing portion 52, a first locking protrusion (=locking protrusion) 53, a connecting portion 54, a gripping portion 55 (=protrusion portion), and a second locking protrusion 56. The first closing portion 51 has a first insertion portion 511 (=insertion portion) inserted into the first opening 21, a first outer portion 512 (=outer portion) connected to the rear side of the first insertion portion 511 and disposed outside the case 2, and a first inner portion 513 connected to the front side of the first insertion portion 511 and disposed inside the case 2.

[0020] The second blocking portion 52 has a second insertion portion 521 (= insertion portion) inserted into the second opening 22, a second outer portion 522 (= outer portion) connected to the rear side of the second insertion portion 521 and arranged outside the case, and a second inner portion 523 connected to the front side of the second insertion portion 521 and arranged inside the case 2. The first and second insertion portions 511, 512 are provided to have the same size and shape as each other and are provided in a cylindrical shape so as to block the first opening 21 and the second opening 22.

[0021] The first outer portion 512 and the second outer portion 522 are provided to have the same size and shape as each other, and are provided in the shape of a cube with a rectangular cross section. As shown in Figures 6 and 7, the lower ends of the first outer portion 512 and the second outer portion 522 are provided to protrude downward (towards the bottom wall portion 231) beyond the first insertion portion 511 and the second insertion portion 521.

[0022] The first interior 513 and the second interior 523 are formed in a cubic shape with a rectangular cross section. The first interior 513 and the second interior 523 are formed to have the same lengths in the up-down direction and the left-right direction.

[0023] Before continuing to explain the structure of the sealing plug 5, the partition wall 43 provided on the base 4 will be described. As shown in FIG. 5, the base 4 is provided with a partition wall 43 facing the right side of the first interior 513 and a partition wall 43 disposed in the gap between the first interior 513 and the second interior 523. A side wall 42 faces the left side of the second interior 523. Returning to the structure of the sealing plug 5, the first interior 513 and the second interior 523 described above are each provided with a pair of ribs 514, 514 and 524, 524 on their left and right side surfaces. The ribs 514, 514 are positioned at the same position in the front-to-rear direction. The ribs 524, 524 are also positioned at the same position in the front-to-rear direction. Furthermore, the distance from the first opening 21 to the pair of ribs 514, 514 provided in the first interior 513 is shorter than the distance from the second opening 22 to the pair of ribs 524, 524 provided in the second interior 523.

[0024] As a result, the rib 514 provided in the first interior 513 and the rib 524 provided in the second interior 523 are positioned differently in the front-to-rear direction. If the ribs 514 and 524 were positioned at the same position in the front-to-rear direction, the gap between the first interior 513 and the second interior 523 would need to be wider than the width of two ribs, and the sealing plug 5 would be larger in the left-to-right direction. In contrast, according to this embodiment, the positions of the ribs 514 and 524 in the front-to-rear direction are different, so the gap between the first interior 513 and the second interior 523 can be wider than the width of one rib, allowing for a more compact sealing plug 5. This also allows the length of the first interior 513 in the front-to-rear direction to be shorter than the length of the second interior 523 in the front-to-rear direction. That is, the length of the first closing portion 51 from the first opening 21 to the tip inside the case 2 is shorter than the length of the second closing portion 52 from the second opening 22 to the tip inside the case 2.

[0025] As shown in Fig. 4, the first locking projection 53 is provided to protrude from the first interior 513 of the first closing portion 51 toward the bottom wall portion 231 (downward) of the lower case 23. The first locking projection 53 has a projection 531 provided on its front side surface. As shown in Fig. 6 and other figures, when the first locking projection 53 is engaged with the locking hole 45, the projection 531 is positioned below the bottom wall portion 41 of the base 4 (toward the bottom wall portion 231 of the lower case 23). The projection 531 is provided with a first tapered surface 532 that is provided closer to the bottom wall portion 231 (lower side) than the apex and whose height decreases with increasing distance from the apex, and a second tapered surface 533 that is provided on the side farther from the bottom wall portion 231 than the apex (upper side) and whose height decreases with increasing distance from the apex.

[0026] 3 and the like, the connecting portion 54 connects the lower ends of the first outer portion 512 and the second outer portion 522. The grip portion 55 is provided so as to extend from the lower ends of the first outer portion 512 and the second outer portion 522, which are arranged outside the case 2, to the connecting portion 54, and protrudes rearward (outside the case 2). The lower ends of the first outer portion 512 and the second outer portion 522 are arranged to protrude downward further than the first insertion portion 511 and the second insertion portion 521, and therefore the grip portion 55 is arranged lower than the first insertion portion 511 and the second insertion portion 521.

[0027] 4 and 5, the second locking projection 56 is provided continuously from the upper surface of the first inner portion 513 to the upper surface of the second inner portion 523, and protrudes upward. The second locking projection 56 protrudes upward further than the first insertion portion 511 and the second insertion portion 512.

[0028] Next, a procedure for attaching the above-mentioned sealing plug 5 to the first opening 21 and the second opening 22 will be described. First, with the upper case 24 removed from the lower case 23, the base 4 is housed in the lower case 23. At this time, as shown in FIG. 7 , when the positioning portion 233 provided on the lower case 23 is inserted into the positioning portion 44 provided on the base 4, the base 4 is positioned relative to the lower case 23.

[0029] Thereafter, the lower case 23 and the base 4 are fixed together by screwing or the like. In this state, the first insertion portion 511 and the second insertion portion 521 of the sealing plug 5 are inserted from the upper openings of the first opening 21 and the second opening 22 of the lower case 23. Furthermore, the first locking protrusion 53 is inserted into the locking hole 45. At this time, the protrusion 531 is deformed along the first tapered surface 532 of the protrusion 531, and the protrusion 531 can pass through the locking hole 45 smoothly.

[0030] When the protrusion 531 passes through the locking hole 45 and is positioned below the bottom wall portion 41 of the base 4, the first locking protrusion 53 is locked with the locking hole 45. At this time, the second locking protrusion 56 is locked with the side wall portion 232 between the first opening 21 and the second opening 22 in the front-to-rear direction, as shown in FIG. 5 . Thereafter, the upper case 24 is attached and fixed to the lower case 23, whereby the sealing plug 5 can be attached to the first opening 21 and the second opening 22.

[0031] Next, the procedure for removing the sealing plug 5 from the first opening 21 and the second opening 22 will be described. First, the upper case 24 is removed from the lower case 23. Then, an operator grasps the gripping portion 55 and pulls it diagonally upward. At this time, the protrusion 531 deforms along the second tapered surface 533 of the protrusion 531, and the protrusion 531 can be smoothly passed through the locking hole 45 and removed from the base 4.

[0032] According to the embodiment described above, the locking protrusion 53 of the sealing plug 5 is locked in the locking hole 45 provided in the case 2. Therefore, when mounted, the sealing plug 5 is unlikely to come off the first opening 21 and the second opening 22, and the sealing plug 5 can be easily removed by releasing the lock between the first locking protrusion 53 and the locking hole 45. In practice, a plurality of first openings 21 and second openings 22 are provided, and depending on the vehicle specifications, some of the first openings 21 and second openings 22 may be unused and left blocked by the sealing plug 5 when mounted on the vehicle. According to the embodiment described above, the sealing plug 5 is locked to the base 4, and therefore will not come off even when the upper case 24 is opened, improving workability.

[0033] According to the embodiment described above, the first locking projection 53 is provided to protrude downward, and the locking hole 45 is provided to penetrate in the up-down direction. This allows the first locking projection 53 to be easily locked or unlocked from the locking hole 45 by passing the first locking projection 53 through the locking hole 45 from the up-down direction.

[0034] According to the embodiment described above, the protrusion 531 of the first locking protrusion 53 is provided with the first tapered surface 532 and the second tapered surface 533. As a result, the protrusion 531 deforms along the first tapered surface 532 when locked (attached), and the protrusion 531 deforms along the second tapered surface 533 when unlocked (removed), making it possible to lock or unlock the locking protrusion 53 and the locking hole 45 even more easily.

[0035] According to the embodiment described above, the sealing plug 5 has a first closing portion 51 that covers the first opening 21, a second closing portion 52 that covers the second opening 22, and a connecting portion 54 that connects the first closing portion 51 and the second closing portion 52. This allows one sealing plug 5 to close two openings, the first opening 21 and the second opening 22.

[0036] According to the embodiment described above, the first locking projection 53 is provided in the first interior 513 of the first blocking portion 51. A force is applied to the sealing plug 5 due to vibration or the like, with the first insertion portion 511 acting as a fulcrum. However, since the first locking projection 53 is provided in a position close to the first insertion portion 511, the insertion / removal force of the first locking projection 53 in the locking hole 45 is increased, making it even more difficult for the sealing plug 5 to come off.

[0037] According to the embodiment described above, the positioning portion 233 provided on the lower case 23 protrudes toward the second interior 523 of the second closing portion 52, and the first locking projection 53 protrudes from the first interior 513 of the first closing portion 51. This prevents interference between the positioning portion 233 and the first locking projection 53.

[0038] According to the above-described embodiment, the sealing plug 5 is provided with the grip portion 55. This allows the sealing plug 5 to be easily removed by holding the grip portion 55. Furthermore, by providing the grip portion 55 closer to the bottom wall portion 231 than the first and second insertion portions 511 and 521, the distance between the fulcrum (the first and second insertion portions 511 and 521) and the point of action (the grip portion 55) is increased, making it possible to remove the sealing plug 5 even more easily.

[0039] 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.

[0040] For example, in the above-described embodiment, one sealing plug 5 is used to close the first opening 21 and the second opening 22, which are arranged side by side, but this is not limiting. The first opening 21 and the second opening 22 may be closed by separate sealing plugs 5.
