In such conventional waterproof outlets, the outlet is covered with a canopy that makes it difficult to see, making it inconvenient to operate when inserting a plug.

On the other hand, there is a known waterproof wiring device in which the eaves protruding from the lower part of the bulge are made of a transparent material so that the insertion port can be seen, for example, as seen in Japanese Utility Model Publication No. 56-52622. It is being This product is convenient and allows you to insert the plug while looking through the eaves in a brightly lit area, which greatly improves work efficiency. However, on the other hand, there is a drawback that in dark places such as at night, the insertion port cannot be seen even through the transparent eaves.

Further, Japanese Utility Model Publication No. 49-34705 describes an electrical outlet in which a light-shielding portion is provided on the front surface of a translucent lid having an outlet, and light from an indicator light provided at the rear is guided to the outlet. This device has the advantage that the socket can be seen even in the dark, but on the other hand, it lacks a transparent visor and requires a light-shielding part on the lid to reflect light and guide it to the socket.

[The problem that the idea aims to solve]

As described above, although the technology described in Utility Model Publication No. 56-52622 made the eaves transparent, it still had the disadvantage that the insertion port could not be seen in a dark place.
The technology described in Japanese Patent Publication No. 34705 lacks waterproofness because it lacks a transparent eaves, and also has a complicated structure and is troublesome to manufacture because it requires a light-shielding part.

This invention provides a transparent window in the eaves to make the operating section visible, and a light emitting element is installed to combine the function of a pilot lamp and the function of illuminating the operating section, so that the operating section can be clearly seen through the transparent window even in the dark.

It is placed opposite. Thus, the front plate 41 closes the opening of the bulge 3. Furthermore, it is fixed within the bulge 3 by a support piece 31 that projects from the inner surface of the bulge 3 .

The eaves 5 has a window portion 55 made of transparent synthetic resin.
The base portion is fixed to the opening edge of the bulging portion 3 by means of thermocompression bonding or the like so as to protrude and cover the front plate 41 . As shown in FIGS. 4 and 5, one end 51 of the window 55 is located within the bulge 3, and its edge forms a slope and faces the light-receiving element 6.
Further, the inner surface of the other end of the window portion 55 of the eaves 5 is formed with a light guide portion 53 forming a slope facing the front plate 41. Note that if the light guide portion 53 has a rough surface, it will be more convenient for light guide. Also,
Surfaces from which light is not desired to be emitted, such as the tip end surface 54 of the eaves 5, may be made light reflective.

Next, the function of this waterproof outlet will be explained with reference to FIG. When the power receiving terminal (not shown) is connected to a power source, conduction is established to the receiving metal fitting 43 of the functional section 4, and the light emitting element 6 emits light. Then, the light from this light emitting element 6 is transmitted from the light receiving section 52 to the window section 5 of the eaves 5.
