Description of the Related Art In this type of electrical junction box, as shown in FIG. 4, an upper case 2 is inserted into a lower case 1 to lock an outer wall 1a of the lower case 1 and an outer wall 2a of the upper case 2. In some cases, the bus bar 3 and the insulating plate 4 may be stacked and housed inside. FIG.
In the electric junction box of No. 2, the lower case 1 and the upper case 2 are locked by locking the locking claws 5 protruding from the inner surface of the lower case outer wall 1a on the upper surface of the upper case 2.

点がある。In order to form the lock claw 5, unless a slide mold is used for the bottom wall 1b of the lower case 1 which is resin-molded with a mold, a die-cut hole shown by an imaginary line (chain line) in FIG. 6 inevitably occurs. Therefore, as shown in FIG. 4, if the lower case bottom wall 1b has a structure in which the die-cutting hole 6 is not formed, the molding die becomes complicated and the cost becomes high.

Although the cost can be reduced by molding, there is a problem that the die-cutting hole 6 is opened in the lower case bottom wall 1b and water is generated from the die-cutting hole 6 into the case. Therefore, as shown in FIG. 5, it is necessary to further attach the lower cover 7 below the lower case 1 to prevent the die-cutting hole 6 from being exposed to the outer surface.

できる。In the electrical junction box according to the first aspect of the present invention, the upper case is incorporated inside the lower case, and in that case,
For the lock claw protruding from the inner surface of the outer wall of the lower case,
The locked claw protruding from the outer surface of the outer wall of the upper case is pushed downward, and the lock claw is locked to the upper surface of the locked claw to assemble and fix the lower case and the upper case. In this assembled and fixed state, the lower claw bottom wall has a lock claw molding die-cutting hole at a position along the outer wall facing the lock claw, and the inside of the case of the opening is the first waterproof frame wall. being surrounded. Further, the outer wall of the upper case extends along the inner surface of the outer wall of the lower case, and at the position of the die-cutting hole, the second waterproof frame wall which is continuous with the outer wall of the upper case and projects inside the case surrounds the first waterproof frame wall. Therefore, the infiltration of water into the case surrounded by the outer case outer wall from the die-cutting hole is first blocked by the first waterproof frame wall, and further,
A second waterproof frame wall of the upper case blocks the housing portion such as the bus bar and the insulating plate. In this way, it is possible to reliably prevent water from entering the inside of the case from the lock claw molding die-cutting hole.

高密度に収容することができる。Further, the housing portion for the bus bar and the insulating plate is surrounded by the outer wall of the upper case and the second waterproof frame wall to ensure waterproofness, but the outer wall of the upper case has a locked claw protruding from the outer surface. And since the second waterproof frame wall extends along the inner surface of the outer wall of the lower case except for the portion protruding toward the inner side, the volume of the accommodating portion can be increased, and the electric junction box is enlarged accordingly. Without
It can be housed in high density.

浸水が生じることはない。According to a second aspect of the present invention, the first waterproof frame wall surrounding the die-cutting hole for forming the lock claw has a horizontal U-shaped cross section, which is erected upward from the bottom wall and is continuous with the outer wall. The water that tries to enter from the bottom of the lower case must pass through the inside of the square tube, so to speak, and must enter the inside of the case until it exceeds its upper end. Therefore, if the upward pressure from below is not strong, it must enter the inside. I can't. Further, even if water is flooded over the first waterproof frame wall, since the second waterproof frame wall of the upper case exists continuously with the outer wall of the upper case, it is surrounded by the outer wall and the second waterproof frame wall. No water will enter the housing of the busbar and the insulating plate.

続させている。The upper case 11 is positioned so as to face the first waterproof frame wall 15 of the lower case 10, that is, directly below the locked claws 17, so as to substantially contact the inner surface of the first waterproof frame wall 15 on the case side. A second waterproof frame wall 18 having a U-shaped cross section is formed continuously with the outer wall 11a. That is, both ends 18a of the second waterproof frame wall 18 are connected to the lower part of the outer wall 11a along the lower case outer wall 10a, and the second waterproof frame wall 18 is formed with a part of the lower part of the outer wall 11a recessed inwardly of the case. And the upper surface 18b of the second waterproof frame wall 18 is continuous with the lower surface 11c of the concave portion 11b provided with the locked claw 17.
