The width from right to left of bulkhead 61 (along the array of following bus-bar upper terminal 15) slightly is wider than the width from right to left of lower connector housing 50.That is to say that bulkhead 61 is formed on the zone of the slightly wide width of width with zone more set than following bus-bar upper terminal 15 (along the array of bus-bar upper terminal 15 down).The upper surface of bulkhead 61 forms conical surface 63, and it reaches the highest around in the middle of its width from right to left, and all descends towards right side and left side.And, be provided with the waterproof sidewall sections 64 that extends from the corresponding right-hand member and the left end of bulkhead 61 downwards.This waterproof sidewall sections 64 covers the side of corresponding outermost bus-bar upper terminal 15 down (be arranged on the array of the following bus-bar terminal 15 on the upper surface of lower connector housing 50 in the middle of outermost), and its end portion extends to the top 54 of lower connector housing 50.The distal portions of each left and right sides waterproof sidewall sections 64 is all partly removed on the side within it, thereby has prevented the corner interference at the top 54 of lower connector housing 50, and forms a slight clearance above the corner.So, formed the notch portion 64A that corresponding corner is fitted into them.
Next, the as above operation and the effect of the present embodiment of structure will be explained.
When having water to enter electric connection box 1 owing to rain, carwash etc., water flows down along the rear surface of lid 30, the surface of encapsulating material 26 etc.Water along the rear surface of lid 30 arrives the guide 65 that is arranged on down bus-bar upper terminal 15 tops, and is directed to jag along the inclined-plane of guide 66.Then, water drips from jag, falls on the bulkhead 61.On the other hand, arrive bulkhead 61 in the encapsulating material 26 that is embedded to down bus-bar upper terminal 15 tops along the water on the surface of encapsulating material 26.Then, water accumulates in from the bulkhead 61 at the top 54 of top covering lower connector housing 50 and by bulkhead 61 and stops, thereby can not arrive the top 54 of lower connector housing 50.Accumulate on the top 54 so prevented water, the result has prevented to be arranged on the short circuit between the following bus-bar upper terminal 15 on the top 54.In the present embodiment, because spatial limitation etc., following bus-bar upper terminal 15 is provided with at interval with short, and bus-bar upper terminal 15 also may be short-circuited even therefore there is a spot of water to arrive down.Therefore, in the case, bulkhead 61 is especially effective.
And bulkhead 61 is integrally formed with displacement restricted part 60, thereby under the situation that does not increase the number of components, has prevented distortion and short circuit between time bus-bar upper terminal 15.
Water on the bulkhead 61 is directed to right side or left side along the conical surface 63 on the upper surface that is formed on bulkhead 61, flows along waterproof sidewall sections 64 then, thus the outer wall surface of arrival lower connector housing 50.Because the width from right to left of bulkhead 61 slightly is wider than the width from right to left (along the width of the array that descends bus-bar upper terminal 15) in the zone that comprises following bus-bar upper terminal 15, so the water that drips from bulkhead 61 any sides all can be directed on the zone that bus-bar upper terminal 15 wherein is not set down.Waterproof sidewall sections 64 covers the side of bus-bar upper terminal 15 under the corresponding outermost, and extends to such an extent that make its elongated end be resisted against on the outer wall of lower connector housing 50.So the top 54 of bulkhead 61, waterproof sidewall sections 64 and lower connector housing 50 is around following bus-bar upper terminal 15.Thereby, prevented to be splashed to the inboard, and arrived bus-bar upper terminal 15 down from the water that the right side or the left side of bulkhead 61 flow down.
The water retaining wall 62 that projects upwards is arranged on lid 30 lateral edges of bulkhead 61.Thereby, prevented that being directed to the water of bulkhead 61 by guide 65 drips from the edge, front side (being guide 65 sides) of bulkhead 61, promptly turn back to the rear surface of cover plate part 31 grades, and arrive bus-bar upper terminal 15 down.And the rear side of bulkhead 51 (being circuit structure 10 sides) is edge embedded in encapsulating material 26.Therefore, between the surface of bulkhead 61 and encapsulating material 26, do not exist to be used for gap that water is passed through, thereby must make water be kept away from down the nearside (being that circuit structure 10 connects sides) of bus-bar upper terminal 15.And bulkhead 61 extends feasiblely, and its leading edge is located on the last front side of extension 15B of the lateral edges (that is the edge on the opposite side of circuit structure 10) that connects raised portion 15A.So the exposed portions serve of each raised portion 15A is whole to be covered by bulkhead 61, this exposed portions serve is outstanding from encapsulating material 26.Thereby, prevented that water from arriving raised portion 15A, that is to say, further must keep water away from following bus-bar upper terminal 15.Because the through hole 55 that also passes of bulkhead 61, arrive through hole 55 and invade in the housing 51 so prevented water from top covering extension 15B.
Water on the outer wall surface of lower connector housing 50 flows down along outer wall surface, and is discharged into the outside through drain outlet 25 or draining window 53.
According to present embodiment, as mentioned above, bulkhead 61 is formed on the displacement restricted part 60 that is provided for preventing down 15 displacements of bus-bar upper terminal, thereby from the upper surface of top covering lower connector housing 50.Thereby, having prevented that water from accumulating on the upper surface of lower connector housing 50, the result has prevented the short circuit between time bus-bar upper terminal 15.And, use single member just to realize preventing down distortion and short circuit between the bus-bar upper terminal 15.
The upper surface of bulkhead 61 forms from its conical surface 63 of descending towards left and right sides of the centre of width from left to right.Thereby the water on the bulkhead 61 is directed to by the inclined-plane along this conical surface 63 and comprises the outside in the zone of bus-bar upper terminal 15 down, is discharged from then.So, discharged the water that accumulates on the bulkhead 61, prevented the short circuit between time bus-bar upper terminal 15 simultaneously.
