Patent 5684600

A device that is used outdoors, such as a vehicle, is required to have a mechanism that prevents rainwater from entering. In the lighting device described in Patent Document 1, a water stop structure of the light source itself is described in which water entering through the harness is stopped by packing.
In the conventional lighting device, it is only the water stop structure of this light source itself, and nothing is described about the water stop between the light source and the design cover.

  As a water blocking structure between the light source and the design cover, generally, a cushioning seal member is sandwiched between the two. In particular, in the illumination device having a configuration in which the light source is disposed on the surface of the design cover, the seal member is disposed on the surface of the design cover, and the light source is disposed on the surface.

In the configuration in which the seal member is sandwiched, since the seal member is exposed, water pressure is directly applied to the seal member. Then, deterioration of the seal member itself is promoted. Further, the gap is generated by the thickness of the seal member, and the appearance is deteriorated.
Furthermore, the seal member is often annular in order to obtain a water blocking structure, and such a shape has a problem that the assemblability (workability at the time of attachment) is low.

  The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a charging device which is excellent in waterproofness between a light source (illumination unit) and a design cover (wall member) to which the light source is fixed. Do.

The charging device of the present invention for solving the above problems is
A wall member having a current-carrying connector portion to which a plug-in plug connected to an external power source is connected,
An illumination unit which is received by the wall member and irradiates light to the conduction connector;
A joint having a double-sided adhesive tape for joining and fixing the lighting unit to the wall member;
A charging device having
The lighting unit includes a main body including a light emitting unit that emits light, and a connector unit that penetrates the wall member and through which electricity flows to the light emitting unit.
At least one of the wall member and the facing surface of the lighting unit has a stepped portion separated from the other on the outer periphery of the through hole through which the connector portion penetrates the wall member, and the double-sided adhesive tape is compressed The light emitting device is characterized in that the wall member and the illumination portion are in close contact with each other on the outer periphery of the step portion, while being disposed in the step portion in a state of being closed.

  In the charging device of the present invention, the illumination unit for irradiating the conductive connector with light is provided on the wall member provided with the conductive connector to which the plug is connected. For this reason, light can be irradiated to the electricity supply connector part, and the insertion position of the electricity supply connector part can be visually recognized reliably.

  And in the charging apparatus of the present invention, at least one of the facing surfaces of the wall member and the lighting unit has a stepped portion separated from the other on the outer periphery of the through hole where the connector portion penetrates the wall member, The double-sided adhesive tape is disposed in the step portion in a compressed state, and the wall member and the illumination portion are in close contact with the outer periphery of the step portion. The close contact between the wall member and the illumination portion on the outer periphery of the step portion prevents a gap from being generated between the wall member and the illumination portion, and foreign matter intrudes into the connector portion and the through hole through the gap. Is being suppressed.

In addition, the charging device of the present invention is provided in the step portion in a compressed state even if a liquid such as water (indeterminate foreign matter) or a fine foreign matter intrudes between the wall member and the illumination unit. The double sided adhesive tape suppresses further penetration.
As a result, the charging device of the present invention exerts the effect of suppressing foreign matter from entering the inside of the charging device 1 through the through hole.
