SUMMARY OF THE INVENTION

It therefore object present invention provide favorable electrical junction box which intrusion water prevented without incurring rise cost.

In order achieve above object, according present invention, there provided electrical junction box comprising:

a main body, having contain portion for containing electric function components therein;

a lid member, covering open part main body;

a fixing leg, provided so extend side wall main box being near butting area which lid member engaged with main body, fixing leg mounted exterior structure;

a water prevention wall, provided upper face base part fixing leg so prevent intrusion water into butting area.

Preferably, water prevention wall integrally formed with fixing leg.

Preferably, water prevention wall provided so project upwardly parallel with side wall main body.

Preferably, water prevention wall formed shape rectangular flat plate.

Preferably, water prevention wall formed shape curved plate.

Preferably, convex portion provided outer face water prevention wall.

In above configuration, because water prevention wall provided upper face base part fixing leg projecting manner, water flowing along upper face fixing leg collide against water prevention wall, even case where high pressure cleaning water been splashed over this fixing leg.

Then, water which collided against water prevention wall not flow into gap butting area between body electric junction box lid with strong force, because running force water decreased or direction flow dispersed, hence, intrusion water into interior electrical junction box prevented.

Further, water prevention wall provided projecting manner by integral molding with body electrical junction box, there no need employing separate part such packing, rise cost due increase components number assembling works avoided.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

An embodiment invention described detail referring attached drawings.

FIG. 1 perspective view showing general structure electrical junction box according embodiment invention, FIG. 2 sectional view essential part electrical junction box shown FIG. 1, FIG. 3 enlarged sectional view part denoted by III FIG. 2.

The electrical junction box 11 present embodiment fuse box for containing electrical function components such fuses, relays containing space which defined by body 12 electrical junction box made synthetic resin lid member 13 covering upper open part body 12 electrical junction box made synthetic resin.

It noted that inside containing space body 12 electrical junction box, there installed fixed relay fuse storing part (not shown) which includes plurality fuse connector parts relay connector parts for engaging mounting fuses or relays, terminal connecting parts wire harness.

The electrical junction box 11 fixed with bolts or like vehicle panel (an exterior structure) or like engine room, by way plurality fixing legs 14 , 15 which are provided so extend body 12 electrical junction box.

As shown FIG. 1, pair fixing legs 15 back face side are provided near butting area 17 body 12 electrical junction box against lid member 13 so extend diagonally upwardly shape curved arm, because places for electrical junction box fixed with bolts are positioned relatively high.

Moreover, each fixing legs 15 water prevention wall 20 provided upper face its base part projecting manner, for preventing intrusion water into butting area 17 . The water prevention wall 20 integrally formed with body 12 electrical junction box well fixing legs 15 , when body 12 formed by injection molding.

The water prevention wall 20 provided so project upwardly parallel with side walls lid member 13 body 12 electrical junction box, formed such size shape, shown FIG. 3, that water (an arrow A) flowing along upper face fixing leg 15 reliably blocked.

When electrical junction box 11 mounted vehicle panel, fixing leg 14 provided lower end front face body 12 electrical junction box, pair fixing legs 15 provided near butting area 17 upper part back face are fastened with bolts fix electrical junction box.
