The width of the waterproof wall 50 is slightly wider to the left and right than the width of the lower connector 40 and the region where the horizontal portions 15A of the plurality of lower bus bar terminals 15 are disposed. Further, the edge of the waterproof wall 50 on the cover 30 side reaches to the vicinity of the back surface of the lid plate portion 31, while the edge on the circuit component 10 side has a potting material (see FIG. (Not shown). The upper surface of the waterproof wall 50 is a tapered surface 52 that is inclined downward toward the left and right ends with the substantially central position in the left-right direction as the peak of the mountain. The waterproof side wall 53 is suspended from the left and right ends of the waterproof wall 50, and the lower end of the waterproof wall 50 extends to a position reaching the ceiling 42 of the lower connector 40.

Further, a water blocking wall 54 protruding upward is provided at the edge on the cover 30 side, and this water blocking wall 54 substantially contacts the lower surface of the guide piece 33 provided on the back surface of the cover 30 described later. It protrudes to the position where it touches. The water blocking wall 54 is formed across the entire width of the waterproof wall 50.

この防水壁５０の下部には、変位規制部５５が防水壁５０と一体的に設けられている。この変位規制部５５は、水平部１５Ａを上側から押さえることにより、ハウジング４１への外部コネクタの嵌合に伴って水平部１５Ａが上方へ変位するのを防止している。変位規制部５５は、左右方向の幅が水平部１５Ａが並列されている範囲にわたる板状をなし、その左右方向幅における略中央部と枠体２１の下枠部２１Ｂとの間には架橋部５６が差し渡されている。そして、変位規制部５５の下面５７（水平部１５Ａとの対向面）には、各水平部１５Ａに対応する位置毎に第２リブ５８が設けられ、この第２リブ５８の下面が各水平部１５Ａに対し上側から当接している。この第２リブ５８については第１リブ４５と併せて後ほど詳しく説明する。   A displacement restricting portion 55 is provided integrally with the waterproof wall 50 at a lower portion of the waterproof wall 50. The displacement restricting portion 55 prevents the horizontal portion 15A from being displaced upward in accordance with the fitting of the external connector to the housing 41 by pressing the horizontal portion 15A from above. The displacement restricting portion 55 has a plate shape in which the width in the left-right direction extends in a range in which the horizontal portions 15A are arranged in parallel, and a bridging portion is provided between the substantially central portion in the left-right width and the lower frame portion 21B of the frame body 21. 56 is handed over. And the 2nd rib 58 is provided in the lower surface 57 (surface facing the horizontal part 15A) of the displacement control part 55 for every position corresponding to each horizontal part 15A, and the lower surface of this 2nd rib 58 is each horizontal part.

The guide piece 33 protrudes from the back surface of the cover plate portion 31 toward the back surface side, and the protruding end reaches a position slightly above the water blocking wall 54 in the back surface direction. The upper surface of the guide piece 33 is a guide surface 34 that is inclined downward toward the protruding end side of the guide piece 33.

さて、前述した第１リブ４５および第２リブ５８について詳しく説明する。図５には、下側バスバー端子１５の水平部１５Ａが第１リブ４５と第２リブ５８とによって挟まれた状態を表す部分拡大断面図を示した。   Now, the first rib 45 and the second rib 58 will be described in detail. FIG. 5 is a partially enlarged cross-sectional view showing a state in which the horizontal portion 15A of the lower bus bar terminal 15 is sandwiched between the first rib 45 and the second rib 58.

第１リブ４５は、それぞれ下部コネクタ４０の上面４４から上方に突設され、各水平部１５Ａに対し下側から当接している。そして、各第１リブ４５の左右方向（水平部１５Ａの並列方向に沿う方向）幅は、各水平部１５Ａの左右方向幅よりも狭くされている。これにより、各第１リブ４５において水平部１５Ａに当接している当接面４７の左右方向幅は、各水平部１５Ａの左右方向幅よりも狭くなっている。   The first ribs 45 project upward from the upper surface 44 of the lower connector 40 and are in contact with the horizontal portions 15A from below. The width of each first rib 45 in the left-right direction (the direction along the parallel direction of the horizontal portions 15A) is narrower than the width in the left-right direction of each horizontal portion 15A. Thereby, the left-right direction width | variety of the contact surface 47 contact | abutted to the horizontal part 15A in each 1st rib 45 is narrower than the horizontal direction width | variety of each horizontal part 15A.

また、各第１リブ４５間は、それぞれ第１リブ４５の突出高さ分だけ当接面４７より下方に凹んだ第１溝部４８となっている。この各第１溝部４８の底面４９には、各第１溝部４８の長さ方向、言い換えると各第１リブ４５の長さ方向に沿って傾斜する傾斜部４９Ａが設けられている。この傾斜部４９Ａは、回路基板１１側に向かって下っている。   Further, a space between the first ribs 45 is a first groove portion 48 that is recessed downward from the contact surface 47 by the protruding height of the first rib 45. The bottom surface 49 of each first groove portion 48 is provided with an inclined portion 49A that is inclined along the length direction of each first groove portion 48, in other words, along the length direction of each first rib 45. The inclined portion 49A is lowered toward the circuit board 11 side.

一方、第２リブ５８は、それぞれ変位規制部５５の下面５７から下方に突設され、各水平部１５Ａに対し上側から当接している。各第２リブ５８は、図３に示すように、それぞれ各水平部１５Ａの延出方向に沿う細長い形状をなし、その左右方向（水平部１５Ａの並列方向に沿う方向）幅は各水平部１５Ａの左右方向幅よりも幅狭に形成されている。また、各第２リブ５８間は、それぞれ第２リブ５８の突出高さ分だけ第２リブ５８の下面よりも上方に凹んだ第２溝部５９とされている。   On the other hand, the second ribs 58 project downward from the lower surface 57 of the displacement restricting portion 55, and are in contact with the horizontal portions 15A from above. As shown in FIG. 3, each of the second ribs 58 has an elongated shape along the extending direction of each horizontal portion 15A, and the width in the left-right direction (the direction along the parallel direction of the horizontal portions 15A) is equal to each horizontal portion 15A. It is formed narrower than the width in the left-right direction. Further, a space between the second ribs 58 is a second groove portion 59 that is recessed above the lower surface of the second rib 58 by the protruding height of the second rib 58.

次に、上記のように構成された本実施形態の作用および効果について説明する。
降雨や車両の洗浄等によって電気接続箱１内に水滴が浸入すると、その水滴が、下部コネクタ４０の上面４４に至り、水平部１５Ａ周辺に付着してしまうことがある。 Next, the operation and effect of the present embodiment configured as described above will be described.
If water droplets enter the electrical junction box 1 due to rain or vehicle washing, the water droplets may reach the upper surface 44 of the lower connector 40 and adhere to the periphery of the horizontal portion 15A.

一の水平部１５Ａ周辺に付着した水滴は、下部コネクタ４０の上面に沿って隣接する水平部１５Ａの方へ伝わっていく。ここで、水平部１５Ａ間に第１溝部４８がない場合、この水平部１５Ａ周辺に付着した水滴は、天井部４２の上面４４を水平方向に広がることになるから隣りに配されている水平部１５Ａに達しやすい。特に、スペースの都合等により下側バスバー端子１５間ができるだけ狭く配されている場合においては、水平部１５Ａ間の沿面距離は十分に確保されず、少量の水分が付着しただけであっても隣り合う下側バスバー端子１５が短絡してしまう可能性がある。しかし、本実施形態では、各第１リブ４５間の凹み分だけ水平部１５Ａ間における沿面距離を稼ぐことができるから、一の水平部１５Ａ周辺に付着した水分が隣接する水平部１５Ａに到達しにくくなり、下側バスバー端子１５間の短絡が回避される。   Water droplets attached to the periphery of one horizontal portion 15 </ b> A travel along the upper surface of the lower connector 40 toward the adjacent horizontal portion 15 </ b> A. Here, when there is no first groove portion 48 between the horizontal portions 15A, the water droplets adhering to the periphery of the horizontal portion 15A spread in the horizontal direction on the upper surface 44 of the ceiling portion 42. It is easy to reach 15A. In particular, when the space between the lower bus bar terminals 15 is as narrow as possible due to space or the like, the creepage distance between the horizontal portions 15A is not sufficiently secured, and even if only a small amount of moisture adheres, it is adjacent. The matching lower bus bar terminal 15 may be short-circuited. However, in the present embodiment, the creepage distance between the horizontal portions 15A can be increased by the amount of the recess between the first ribs 45, so that moisture attached to the periphery of one horizontal portion 15A reaches the adjacent horizontal portion 15A. It becomes difficult and a short circuit between the lower bus bar terminals 15 is avoided.

また、第１リブ４５が水平部１５Ａより幅広に形成され、当接面４７が水平部１５Ａより幅方向外側に張り出していると、この当接面４７と水平部１５Ａの側面（当接面４７に対して垂直な面）とによって水平部１５Ａの周りに角部が形成され、この角部に水分が溜まることがある。しかし、本実施形態においては、第１リブ４５の当接面４７の左右方向幅は、各水平部１５Ａの左右方向幅よりも狭くされており、水平部１５Ａの周りに角部が形成されないから、このような事態は回避される。   Further, when the first rib 45 is formed wider than the horizontal portion 15A and the contact surface 47 protrudes outward in the width direction from the horizontal portion 15A, the contact surface 47 and the side surface (contact surface 47 of the horizontal portion 15A). Corners are formed around the horizontal portion 15A, and moisture may accumulate in the corners. However, in the present embodiment, the lateral width of the contact surface 47 of the first rib 45 is narrower than the lateral width of each horizontal portion 15A, and no corner is formed around the horizontal portion 15A. This situation is avoided.

さらに、第１溝部４８に落下した水滴は、その底面４９に設けられている傾斜部４９Ａによって第１溝部４８における回路基板１１側の端縁、つまり下部コネクタ４０の上面４４における背面側の縁部に導かれ、そこから下部コネクタ４０の背面側へ流れ落ちる。こうして水滴は、第１溝部４８の底面４９から容易に排水されるから、第１溝部４８、つまり水平部１５Ａ間に水滴が溜まることはなく、確実に下側バスバー端子１５間の短絡を防止できる。   Further, the water droplets that have fallen into the first groove 48 are inclined by the inclined portion 49A provided on the bottom surface 49 thereof, so that the edge on the circuit board 11 side of the first groove 48, that is, the edge on the back side of the upper surface 44 of the lower connector 40. From there, it flows down to the back side of the lower connector 40. Thus, since the water droplets are easily drained from the bottom surface 49 of the first groove portion 48, the water droplets are not collected between the first groove portion 48, that is, the horizontal portion 15A, and the short circuit between the lower bus bar terminals 15 can be surely prevented. .

また、変位規制部５５の下面５７には第２リブ５８が設けられ、各第２リブ５８間はそれぞれ上方に凹んだ第２溝部５９とされている。ここで、変位規制部５５の下面５７が第２溝部５９のないべた面であって、全面にわたって水平部１５Ａの上面に当接していると、水平部１５Ａ周辺に付着した水滴は、その下面５７と第１溝部４８の底面４９との間で押しつぶされつつその狭い隙間を水平方向に広がることになる。しかし、本実施形態によれば、水平部１５Ａ周辺に付着した水滴は第２溝部５９の深さ分だけ上方に逃げることができるから、その分水平方向への広がりが抑えられる。したがって、隣り合う水平部１５Ａ間に水滴が行き渡り、下側バスバー端子１５間を短絡させることを確実に回避できる。   Further, a second rib 58 is provided on the lower surface 57 of the displacement restricting portion 55, and a space between the second ribs 58 is a second groove portion 59 that is recessed upward. Here, if the lower surface 57 of the displacement restricting portion 55 is a solid surface without the second groove portion 59 and is in contact with the upper surface of the horizontal portion 15A over the entire surface, water droplets adhering to the periphery of the horizontal portion 15A will be removed from the lower surface 57. And the narrow gap between the first groove 48 and the bottom surface 49 of the first groove 48 spread in the horizontal direction. However, according to the present embodiment, since the water droplets attached to the periphery of the horizontal portion 15A can escape upward by the depth of the second groove portion 59, the spread in the horizontal direction is suppressed accordingly. Therefore, it is possible to reliably avoid a water droplet from spreading between adjacent horizontal portions 15A and short-circuiting between the lower bus bar terminals 15.

以上説明したように本実施形態によれば、下部コネクタ４０の天井部４２の上面４４には、下側バスバー端子１５の水平部１５Ａに対応する位置毎に、各水平部１５Ａに対し下側から当接する第１リブ４５が突設され、各第１リブ４５間はそれぞれ下方に凹んだ第１溝部４８とされている。これにより、各第１リブ４５間の凹み分だけ隣り合う下側バスバー端子１５の水平部１５Ａ間における沿面距離を稼ぐことができる。したがって、一の水平部１５Ａに付着した水滴が隣接する水平部１５Ａに到達しにくくなり、下側バスバー端子１５間の短絡が回避される。   As described above, according to the present embodiment, the upper surface 44 of the ceiling portion 42 of the lower connector 40 has a position corresponding to the horizontal portion 15A of the lower bus bar terminal 15 from the lower side with respect to each horizontal portion 15A. First ribs 45 that abut on each other protrude from the first ribs 45, and first groove portions 48 are recessed downward. Thereby, the creeping distance between the horizontal portions 15 </ b> A of the lower bus bar terminals 15 adjacent to each other by the recesses between the first ribs 45 can be earned. Therefore, water drops attached to one horizontal portion 15A are unlikely to reach the adjacent horizontal portion 15A, and a short circuit between the lower bus bar terminals 15 is avoided.

さらに、第１溝部４８の底面４９には、各第１溝部４８の長さ方向に沿って下る傾斜部４９Ａが設けられている。これにより、各第１溝部４８に伝わる水滴は、その底面４９に設けられた傾斜部４９Ａに誘導されて流れ落ち、下部コネクタ４０の天井部４２から容易に排水される。したがって、この天井部４２上に水が溜まった状態となることが回避され、下側バスバー端子１５間の短絡が確実に防止される。   Furthermore, the bottom surface 49 of the first groove portion 48 is provided with an inclined portion 49 </ b> A that descends along the length direction of each first groove portion 48. As a result, the water droplets transmitted to each first groove portion 48 are guided by the inclined portion 49 </ b> A provided on the bottom surface 49 and flow down, and are easily drained from the ceiling portion 42 of the lower connector 40. Therefore, it is avoided that water is accumulated on the ceiling portion 42, and a short circuit between the lower bus bar terminals 15 is reliably prevented.

また、変位規制部５５の下面５７には、水平部１５Ａに対応する位置毎に各水平部１５Ａに対し上側から当接する第２リブ５８が突設され、各第２リブ５８間はそれぞれ上方に凹んだ第２溝部５９とされている。これにより、水平部１５Ａに付着した水滴は、変位規制部５５の下面５７と第１溝部４８の底面４９との間の狭い隙間で押しつぶされることなく、第２溝部５９の深さ分だけ上方に逃げることができるから、その分水平方向への広がりが抑えられる。したがって、隣り合う水平部１５Ａ間に水分が行き渡り、下側バスバー端子１５間を短絡させることを回避できる。   In addition, on the lower surface 57 of the displacement restricting portion 55, second ribs 58 that abut against the horizontal portions 15A from the upper side are provided at positions corresponding to the horizontal portions 15A, and the spaces between the second ribs 58 are respectively upward. A recessed second groove 59 is formed. As a result, the water droplets adhering to the horizontal portion 15A are not crushed by the narrow gap between the lower surface 57 of the displacement restricting portion 55 and the bottom surface 49 of the first groove portion 48, but upward by the depth of the second groove portion 59. Since it can escape, the spread in the horizontal direction is suppressed accordingly. Therefore, it is possible to avoid short circuit between the lower bus bar terminals 15 due to moisture spreading between the adjacent horizontal portions 15A.
