DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wiring device having a function portion and an insertion port, which is used by inserting a plug blade into an outlet.

[0002]

2. Description of the Related Art Wiring devices of a type in which a plug blade is inserted into a wall-embedded outlet and which can be used as an indicator lamp have been conventionally known.

FIG. 8 is a perspective view showing a conventional wiring apparatus of this kind.

[0004] In the figure, 81 is a case, 82 is a plug blade, and 83 is a display unit.

[0005] The case 81 includes a base 81a and a cover 81b.
And a space is formed inside.

The plug blade 82 protrudes rearward from the back of the base 81a, and can be inserted into an outlet (not shown).

The display unit 83 is a small light source (not shown) housed in the internal space of the case 81 and connected to the plug blade 82, and a display panel arranged at the center of the front surface of the case 81 and covering the light source. 83a. In addition,
Reference numeral 84 denotes a light receiving window of the photo switch, in which a photoconductor and a control circuit (both are not shown) are incorporated, and the light source is automatically controlled in accordance with the surrounding illuminance.

Further, an insertion port (not shown) is provided on the lower surface of the case so that a plug of an electric device can be inserted into the indicator light.

[0009]

However, the conventional indicator light has a problem that its position is difficult to understand because the insertion port is on the lower surface of the case.

Further, by providing the insertion port, even if the position of the insertion port is on the lower surface, it is difficult to make the display portion as large as possible in a given size of the case for the following reasons. Met. That is, a space for accommodating the receiving blade disposed inside the insertion port and the wiring member extending from the plug blade to the receiving blade must be secured in the internal space of the case while maintaining electrical insulation. Because.

For this reason, the light source used for the display unit also uses one neon glow lamp, and the display unit can display the position of the wall embedded outlet at most. On the other hand, there are nightlights that are equipped with a light bulb of about 5 W in order to obtain sufficient brightness, but the bulb and the glove part need to protrude forward from the case, and become considerably large, and not much from the wall. If it protrudes, there is a problem that not only is it dangerous to hit people and objects, but also the wiring device is easily undesirably dropped.

However, in this type of wiring device, there is a strong demand to use a wiring device that is as small as possible and that does not compromise on required functions.

[0013] The present invention provides a wiring device which can secure a sufficient space for a functional portion in spite of a relatively small size of a case, and also has an insertion port arranged on the front of the case to make its existence easy to understand. The purpose is to:
