Figure 3 shows conventional examples of drainage structures for electrical junction boxes such as junction boxes and relay boxes.
This will be explained using FIG. In the figure, reference numeral 1 denotes a busbar circuit board which has busbar circuits 2 on the front and back sides.
3 is a front cover with multiple connector housings 4, 4
... has been established. A plurality of tab terminals 5, 5, . . . project from the busbar circuit 2 both above and below the busbar circuit board 1. Tab terminal 5 is connected to connector housing 4
or 8, to form an electrical connection box. After being connected to external electric wires, etc., a waterproof cover 7 is attached to the electrical junction box to prevent water from penetrating inside. However, if the usage conditions are poor, for example when the connector housing is used for electrical wiring in the engine room of a car, the connector housing may be damaged due to rainwater or temperature changes.
There may also be cases where water or water vapor enters through the terminal receiving hole 4a and becomes liquefied. Such water droplets stay on the inner bottom surface 9, touch the busbar circuit 2, and generate leakage current, causing trouble. Alternatively, the remaining moisture evaporates again due to heat generation in the electrical connection box, contacts the busbar circuit 2, condenses, and becomes water droplets, generating leakage current.
これを防止するために、内底面９に傾斜をつけ
て、滞留した水滴を排水孔１０から排除できるよ
うにしている。 In order to prevent this, the inner bottom surface 9 is sloped so that accumulated water droplets can be removed from the drain hole 10.

One embodiment of the present invention will be described with reference to FIG. In the figure, 1 is a busbar circuit board with busbar circuits 2 arranged on the front and back sides of a single board, 3 is a busbar circuit board 4 that connects relays, etc.
4. This is a front cover with... A plurality of tab terminals 5, 5, . . . project from the busbar circuit 2 in both the upper and lower directions of the busbar circuit board 1. A connector housing 8 is integrally formed on the inner bottom surface 9 so as to penetrate through the inner bottom surface 9. The busbar circuit board 1 is sandwiched between the front cover 3 and the inner bottom surface 9 of the electrical junction box main body 6, and the tab terminals 5 are fitted into the terminal receiving holes 4a, 8a of the connector housing 4 or 8, and the electrical junction box main body 6 is inserted. is formed. Fuses, relays, etc. are fitted into the connector housing 4, a waterproof cover 7 is attached to the upper part of the electrical junction box body, and the connector housing 8 is also connected to an external electric wire from below in the figure (not shown). are fitted.

However, water droplets tend to remain at the position A where the corner 8' of the connector housing 8 and the inner bottom surface 9 intersect, and therefore, the drainage hole 10 A narrow groove 11 towards
is drilled. FIG. 2 is a detailed view of this part, and an enlarged part 12 in the shape of a funnel is formed at the end A of the groove 11 on the corner 8' side. The narrow groove 11 easily absorbs water droplets by capillary action. The water absorbed by this groove 11 flows toward the drainage hole 10 and is discharged outside the electrical connection box. In addition,
Even if the groove 11 does not reach the drain hole 10, if the surface tension of the groove 11 or the inner bottom surface is small, the water will flow to the drain hole, but if this is not the case, draining will be more reliable if the groove 11 is drilled up to the drain hole.
