Similarly, form two second rhones 36 on the upper surface of main part 30, extend its end since the front groove 35F of first rhone 35, makes front groove 35F to the linearly prolongation of arm 31 1 sides (lateral surface of electric connection box P).The prolongation end of second rhone 36 arrives the lateral surface of arm 31.The groove width of second rhone 36 is greater than the groove width of front groove 35F, and it is continuous that the medial surface of the front side of the medial surface of the front side of front groove 35F and second rhone 36 is a face.The drainage path that is made of this first rhone 35 and second rhone 36 is provided with a pair of as follows: go up devices spaced apart at the length direction (left and right directions) of the upper surface of main part 30 and be configured, and extend in the opposite direction, until arm 31 (lateral surface of electric connection box P).
And as shown in Figure 6, in the groove bottom of first rhone 35 and second rhone 36, form the inclined plane 37 that is inclined relative to horizontal.Inclined plane 37 integral body tilt as follows: liquid flows to aftermentioned drainage path 38 through second rhone 36 from first rhone 35.Particularly, in the front groove 35F and rear groove 35R of first rhone 35, be inclined plane 37F, the 37R of descending grade (promptly being inclined relative to horizontal) through its total length formation side (arm 31) outside the Width mediad of main part 30.And, in the groove 35S of left and right sides portion of first rhone 35, form the inclined plane 37S that is descending grade (promptly being inclined relative to horizontal) from rear groove 35R to front groove 35F through its total length.Further, in second rhone 36, form the inclined plane 37A that is descending grade (promptly being inclined relative to horizontal) from first rhone, 35 1 lateral drainage paths 38 (arm 31) through its total length.Remain in the water of first rhone 35, second rhone 36, mobile along with the gradient of inclined plane 37A, F, R, S to the direction of arrow of Fig. 6, arrive drainage path 38.In addition, about the angle of inclination of each inclined plane 37A, F, R, S, its from the top on this inclined plane to being fixing angle bottom, but in the top on inclined plane between bottom, it is different that the angle of inclination also can part.And at inclined plane 37A, F, R, S each other, the angle of inclination can be mutually the same angle, also can be the angle of inclination that differs from one another.
In the lateral surface of each arm 31, be formed on above-below direction (direction parallel) and go up the drainage path 38 that extends with the bearing of trend of arm 31.Until the lower end, except most of zone of upper end, it is poroid to be the perforation of having surrounded above-below direction all around in the drainage path 38 from the upper end of arm for drainage path 38.The upper end of drainage path 38 is communicated with the end of above-mentioned second rhone 36.The bottom of drainage path 38 is as discharge outlet 39 openings.And, in the medial surface (face relative) of arm 31, be formed on the swing restrictions 40 (with reference to Fig. 4) of the groove shape that linearity extends on the above-below direction with the lateral edge portion of framework 21.
Similarly, in the lateral surface of arm 31, form pair of right and left banking motion restrictions 41 in the form of slot.Begin to form this banking motion restrictions 41 from the upper end of arm 31, and it is gone up linearity at above-below direction (being inserted into the identical direction of direction of insertion of housing H with electric connection box P) and extends until the lower end.And, in roughly the latter half zone of banking motion restrictions 41, form a pair of crush rib 42 of extending to the inside from this edge of opening.Further, formation extends to cantilever-shaped elasticity fastening piece 43 downwards on the bottom of banking motion restrictions 41.On the lateral surface of elasticity fastening piece 43, form and fasten projection 43a.
Described fuse box 23 is assembled from the top near framework 21.In assembling process, lateral surface by two arms 31 and the left and right sides edge part of framework 21 slips (two arms 31 are from left and right sides clamping framework 21), and with respect to framework 21 fuse box 23 is located on left and right directions, and by chimeric between the swing restrictions 29,40 that makes framework 21 and fuse box 23, limit arm 31 with respect to the lateral edge portion of framework 21 to the oblique displacement of fore-and-aft direction (banking motion) of intersecting with its length direction, thereby with respect to framework 21 fuse box 23 is located on fore-and-aft direction.And by swing chimeric between the restrictions 29,40, fuse box 23 is directed into predetermined assembling position with respect to framework 21.When fuse box 23 arrives regular assembling position, by screw the bottom of arm is fixed to framework 21, then fuse box 23 and framework 21 keep assembled states.
Under assembled state, the lower end discharge outlet 39 of drainage path 38 in the bottom of framework 21 (casing 20) under shed.
Housing H has: lid 50A; The loam cake 50B open with lower surface, it is assembled on this lid 50A, to cover its upper surface.Lid 50A has: the support component 51 that lower surface is open; With bottom 58, be assembled on this support component 51, to block the opening of its lower surface.
The board 51a of the level of formation and electric connection box P correspondence in support component 51.On board 51a, form pair of right and left and be used to expose the peristome 51H of accessory resettlement section 34, begin at the whole guide portion 52b that forms the angle tubular that downward (inside of first rhone 35) extends that encloses from the edge of opening of each peristome 51H, and begin to form make progress (side opposite) and the bulkhead 52a of guide portion 52b at the angle tubular that a face extends with guide portion 52b whole the circle from the edge of opening of peristome 51H.This bulkhead 52a and guide portion 52b become the tubular fitting portion 52 (location division of the present invention) of the general square shape tubular that board 51a is connected on above-below direction.
And, in the medial surface of support component 51, be formed on the upwardly extending pair of right and left banking motion of upper and lower restrictions 53.Banking motion restrictions 53, by constituting the drain tank 56 of formation above-below direction on the inner surface of back-up block portion 54 for the back-up block portion 54 of lengthwise bulk with from both sides of the edge, the front and back portion a pair of restriction rib 55 that direction is outstanding forwards, backwards of this back-up block portion 54 from the medial surface of support component 51 is outstanding.The formation zone of drain tank 56 begins to form buckling parts 57 until slightly leaning on last position than the lower end on the bottom of drain tank 56 from the upper end of back-up block portion 54.Upper end near the position of the lower surface opening of support component to board 51a forms described banking motion restrictions 53.Form embeded slot 59 on the periphery of bottom 58, it is upwards open, and direction is slenderly extended to the left and right.
When accommodating electric connection box P in the housing H, at first, bottom 58 is unloaded from support component 51, insert electric connection box P, the upper end of the banking motion restrictions 41 of fuse box 23 is fitted to the bottom of banking motion restrictions 53 from the opening of the lower surface of support component 51.Chimeric by between this banking motion restrictions 41,53, restriction electric connection box P is with respect to the banking motion (displacement relatively) of the fore-and-aft direction of support component 51.When this state carried out the insertion of electric connection box, electric connection box P by the fastening between the banking motion restrictions 41,53, was directed to support component 51 with predetermined posture and along predetermined insertion path movement.And, in the second half of insert action, fasten by crush rib 42 and restriction rib 55, become arm 31 (electric connection box P) with respect to the support component 51 confined state of the banking motion of direction (displacement relatively) to the left and right.
And, when electric connection box P arrives regular assembling position, the accessory resettlement section 34 of the upper surface of fuse box 23 is chimeric with the tubular fitting portion 52 of support component 51, thereby restriction electric connection box P is with respect to the support component 51 relative displacement of left and right directions (being inserted into the direction that the direction of support component 51 is intersected with electric connection box P) forwards, backwards.And, the fastening projection 43a of elasticity fastening piece 43 is from fastening to buckling parts 57 simultaneously, thereby limited electric connection box P and fallen (breaking away from from support component 51) downwards with respect to support component 51, electric connection box P remains the state that all is housed in the support component 51 except its bottom.
Afterwards, after bottom 58 being assembled into the opening of lower surface of support component 51, constitute lid 50A, except the upper surface (being used to load and unload the opening of fuse 33) of the accessory resettlement section 34 of upwards exposing from tubular fitting portion 52, the roughly integral body of electric connection box P is housed in the lid 50A.And along with the assembling of bottom 58, the enchasing plate 44 of the lower surface of electric connection box P and the embeded slot 59 of bottom 58 are chimeric.At last, go up to cover its upper surface (opening of the upper surface of accessory resettlement section 34), then finish housing H, and electric connection box P finishes with respect to the operation of accommodating of housing H, finish electric power distribution system if loam cake 50B is assembled into lid 50A.
Electric connection box P is being housed under the state of lid 50A, the upper surface of accessory resettlement section 34 is positioned at the top of board 51a, and the outer peripheral face of this accessory resettlement section 34 is surrounded by bulkhead 52a.And the upper end of bulkhead 52a is positioned at the height roughly the same with the upper end of accessory resettlement section 34.And bulkhead 52a and guide portion 52b have minim gap and in opposite directions mode is surrounded this accessory resettlement section 34 with the outer peripheral face with respect to accessory resettlement section 34.Further, guide portion 52b is towards the outstanding state in the inside of first rhone 35.
In the present embodiment, under the state of electric connection box P being accommodated in the lid 50A, accessory resettlement section 34 is exposed to the outside in the peristome 51H of the upper surface of lid 50A (tubular fitting portion 52), therefore be attached to the water of the upper surface of this lid 50A, the upper surface of the casing 20 (main part 30 of fuse box 56) that may be immersed in electric connection box P from peristome 51H and the gap between the accessory resettlement section 34 of lid 50A.
But, in the present embodiment, on the upper surface of casing 20, be formed with rhone 35,36 until the drainage path 38 of the lateral surface of casing 20, on the groove bottom of rhone 35,36, be formed with the inclined plane 37 that is descending grade towards drainage path 38, therefore the water that remains in the upper surface of casing 20 (main part 30) flow in the rhone 35,36, on inclined plane 37, flow, thus draining conscientiously.
Particularly in the present embodiment, with rhone 35,36 as the pair of right and left of devices spaced apart on the length direction of the upper surface of electric connection box P drainage path and being provided with independently, therefore the structure that forms a rhone with traverse total length substantially on the upper surface of electric connection box is compared, and the longest drainage path that arrives drainage path 38 shortens.Therefore has good drainage performance.
And, because the outer peripheral face of accessory resettlement section 34 and with the inner peripheral surface of first rhone 35 of its encirclement in a face continuously, therefore the water that is attached to the outer peripheral face of accessory resettlement section 34 can not be attached on the upper surface of main part 30, and can be directed to effectively in first rhone 35.
Further, in the present embodiment, accessory resettlement section 34 projects upwards from the upper surface of lid 50A, but owing to be formed with the bulkhead 52a that erects from the edge of opening that makes the peristome 51H that accessory resettlement section 34 exposes among the lid 50A, the water that therefore can prevent to remain in the upper surface of lid 50A (the board 51a of support component 51) is attached to upper surface, the outer peripheral face of accessory resettlement section 34.
Further, in the present embodiment, formed the guide portion 52b that extends towards the inside of first rhone 35 from the edge of opening of peristome 51H downwards, even therefore just in case water is attached to the inner peripheral surface of bulkhead 52a, also can make water flow to the inner peripheral surface of guide portion 52b, thereby can be directed to effectively in first rhone 35 from bulkhead 52a.
And, flow into the water of rhone 35,36, utilization arrives this path of the bottom of casing 20 through drainage path 38 from the upper surface of casing 20 (fuse box 23), carry out draining, even therefore, in this electrical contacts, can not be short-circuited at the lateral surface of casing 20, positive configuration electrical contacts yet.And because drainage path 38 is and connects poroidly, even therefore electric connection box is vibrated, water also can not be exposed to the outside of drainage path 38.
And casing 20 has: framework 21 is configured along the periphery that makes the plate face towards the circuit substrate 11 of vertical direction; With fuse box 23, make arm 31 from extending in mode downwards along the lateral edge portion of framework 21 along the main part 30 of framework 21 upper edge configurations, and in the present embodiment, utilize the form of this fuse box 23, on the main part 30 of fuse box 23, form rhone 35,36, and on arm 31, form drainage path 38, and then the swing restrictions 40 of arm 31 is fastened in the swing restrictions 29 of lateral edge portion of framework 21, having limited fuse box 23 thus is that fulcrum is in the motion that has upwardly sloped front and rear sides with respect to framework 21 with main part 30.In the present embodiment, arm 31 as the formation parent of drainage path 38, therefore with the banking motion limiting unit of fuse box 23 the banking motion limiting unit that is also used as fuse box 23 is compared with the device that arm 31 forms separately respectively, can simplify the shape of fuse box 23.
In the present embodiment, on the holding member 50A of the upper end-face edge portion of electric connection box P and housing H, be provided with location division (accessory resettlement section 34 and tubular fitting portion 52), its by mutual fastening limit electric connection box P in holding member 50A to moving all around, in the support component 51 of holding member 50A and electric connection box P, banking motion restrictions 41 is set, 53, it is configured on the position of leaving downwards from the location division, can to limit the fitting portion that electric connection box P shows location division (resettlement section 34 and tubular fitting portion 52) greatly be the fulcrum banking motion by chimeric mutually.So, be inserted into the electric connection box P in the support component 51, in location division disconnected from each other (resettlement section 34 and tubular fitting portion 52) and banking motion restrictions 41,53, fasten with support component 51, therefore prevented that electric connection box P from being the fulcrum banking motion of direction forwards, backwards with the fitting portion between location division (resettlement section 34 and tubular fitting portion 52).
And, banking motion restrictions 41,53 is extended along the direction of insertion that electric connection box P is inserted in the support component 51, therefore when being inserted into electric connection box P in the support component 51, chimeric by between the banking motion restrictions 41,53, electric connection box P is directed to support component 51 along predetermined insertion path, can make (resettlement section 32 and tubular fitting portion 52) fastening between the location division of electric connection box P and support component 51 effectively.
And the banking motion restrictions 53 of support component 51 1 sides is set near the opening of support component 51, therefore is inserted in the process of support component 51 at electric connection box P, can be by the chimerism of Visual Confirmation banking motion restrictions 41,53.
And, different with present embodiment, when being formed on the different parts with the banking motion restrictions when the location division, because the assembling tolerance of both sides' parts, location division and banking motion restrictions produce position deviation, consequently, when electric connection box P is inserted into support component 51, possibly can't fasten smoothly between the location division.But in the present embodiment, location division of electric connection box P one side (accessory resettlement section 34) and banking motion restrictions 41 are formed on the accessory (fuse box 23), therefore can be because of the fastening generation obstacle of the assembling tolerance between the accessory to (accessory resettlement section 34 and tubular fitting portion 52) between the location division.
(execution mode 2)
Next with reference to Figure 14 the execution mode 2 that the present invention is specialized is described.The electric connection box P of present embodiment 2 is in the electric connection box of above-mentioned execution mode 1, has formed the device of connectivity slot 60 on the upper surface of the main part 30 of fuse box 23.Therefore other structures are identical with above-mentioned execution mode 1, are marked with identical label for identical structure, and omit the explanation of its structure, effect and effect.
So that the mode that is communicated with between pair of right and left first rhone 35 forms connectivity slot 60, its end from the rear groove 35R of each first rhone 35 begins to extend, and makes rear groove 35R to prolonging with arm 31 opposite sides (central authorities' one side of Width) linearity.The medial surface of the rear side of the medial surface of the rear side of connectivity slot 60 and rear groove 35R is a face continuously.And the groove width of the groove width of connectivity slot 60 and rear groove 35R is basic identical, and less than the medial surface of the front side of the front groove 35F interval to the medial surface of the rear side of rear groove 35R.Also form the inclined plane 61 that is inclined relative to horizontal on the groove bottom of this connectivity slot 60, it is similar with the inclined plane 37 on the groove bottom that is formed on first rhone 35 and second rhone 36.This inclined plane 61, cross direction (length direction of main part 30) go up with about the substantial middle position of two first rhones 35 be crestal line 62, (arm 31 sides) are with the descending grade slight inclination towards left and right sides side.That is, pair of right and left inclined plane 62, continuous with chevron in one end (crestal line 62), and in the other end, with respect to the inclined plane 37R of rear groove 35R sleekly or samely link to each other planarly.In addition, the angle of inclination on the angle of inclination of the inclined plane 37R of rear groove 35R and the inclined plane 61 of connectivity slot 60 can be identical angle, also different angles.
Because electric connection box P is equipped on the motor vehicle, therefore when stopping because the road surface tilts or under steam because the vehicle inclination such as rotate, swing, pitch, electric connection box P is sometimes with the big angle tilt of the gradient than the inclined plane 37 of rhone 35,36.In this case, about the water of first rhone 35 that is positioned at a higher side (upside of inclination) in two first rhones 35, may remain on the end of in this first rhone 35 and the opposite side of lateral surface main part 30 (arm 31).But in present embodiment 2, because a pair of first rhone 35 is communicated with by connectivity slot 60, therefore the water of first rhone 35 that is positioned at the upside of inclination passes through connectivity slot 60, can flow into first rhone 35 of the downside that is positioned at inclination, and be discharged to the lateral surface of main part 30 effectively.
And, the inclined plane 62 of connectivity slot 60, with the centre position (the about middle position of the Width of the upper surface of main part 30) of two first rhones 35 is that crestal line 62 tilts with descending grade to both sides, rhone 35,36 clamping crestal lines 62 separately are provided with a pair of to both sides, therefore the water that flow in the connectivity slot 60 can not rest in the connectivity slot 60, and can flow into effectively in the rhone 35,36, and be discharged to outside the main part 30.
(execution mode 3)
Next, with reference to Figure 15 and Figure 16 the execution mode 3 that the present invention is specialized is described.The electric connection box P of present embodiment 3, be in the electric connection box of above-mentioned execution mode 2, with a pair of connectivity slot 63F in front and back, the 63R device that devices spaced apart is provided with on the fore-and-aft direction that the detaching direction (left and right directions) with a pair of rhone 35 intersects of almost parallel each other.The groove width size of this connectivity slot 63F, 63R is greater than front groove 35F and rear groove 35R, the inner surface of the front side of the connectivity slot 63F of front side is a face with respect to the inner surface of the front side of front groove 35F continuously, and the inner surface of the rear side of the connectivity slot 63R of rear side is a face with respect to the inner surface of the rear side of front groove 35R continuously.That is, the medial surface of the medial surface of the front side of the front groove 35F of the medial surface of the front side of the connectivity slot 63F of front side, first rhone 35 and the front side of second rhone 36 is from being connected to the straight line shape.In addition, in first rhone 35, form the slot part that is equivalent to the side slots 35S of connectivity slot 60 sides of formation in above-mentioned execution mode 1 and 2.That is, the flat shape of first rhone 35 is roughly " U " font.And, forming pair of angled face 64 in the groove bottom of each connectivity slot 63F, 63R respectively, it is descending grade from crestal line 65 to first rhone 35.In present embodiment 3, owing to be provided with two connectivity slot 63F, 63R, so drainage efficiency is better.In addition, therefore other structures are identical with above-mentioned execution mode 2, identical structure are marked with identical label, and omit the explanation of its structure, effect, effect.
