The shield skirt 69 of the upper cover 61 surrounds the entire side surface of the main body exposed to the outside. And the position where the large current terminal is exposed is wrapped by the protective guide 71 extending further toward the lower cover 51 than the shield skirt (69).

When water is introduced into the vehicle in such a state, the water flowing down the outer surface of the upper cover 61 is first collected in the drain groove 65 of the flange 63. Therefore, water is permeated by the flange 63 between the upper cover 61 and the main body and prevents water from penetrating into the junction box 50.

In addition, the water collected in the drain groove 65 flows down to a desired position through the drain hole 67 because the drain hole 67 is formed only on a portion of the bottom surface of the flange 63. At this time, since the shielding skirt 69 shields the side surface of the main body, water flowing through the drain hole 67 of the flange 63 does not penetrate into the junction box 50.

In addition, since the front of the large current terminal is shielded by the protection guide 71 extending further toward the lower cover 51 than the shielding skirt 69, the water flowing down through the opening of the large current terminal to the junction box ( 50) Penetration into the interior is also prevented.

Within the scope of the basic technical idea of the present invention, many other modifications are possible to those skilled in the art, and the scope of the present invention is interpreted based on the appended utility model claims. Should be.

As described in detail above, according to the drainage structure of the upper cover of the junction box according to the present invention, the following effects can be expected.

According to the present invention, a flange having a drain hole formed on an outer surface of the upper cover is configured such that water flows through the drain hole of the flange primarily when water is introduced into the vehicle. Therefore, the water can flow down to a desired position, thereby preventing the water from penetrating into the junction box on the outer surface of the upper cover, thereby improving the operation reliability of the junction box.

In addition, the upper cover is further provided with a shielding skirt and a protective guide. Therefore, the shielding skirt surrounds the entire side surface of the main body to prevent the water flowing through the drain hole of the flange from penetrating into the junction box through the lower cover and the main body. In addition, the protection guide prevents water from entering the inside of the junction box by wrapping a portion of the large current terminal exposed to the outside. Therefore, the waterproofness of the junction box is increased, thereby increasing the durability and operation reliability of the junction box.
