Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a wiring device that is used while being fixed outdoors.

[Background technology]

2. Description of the Related Art Conventionally, a wiring device having the configuration shown in FIG. 2 has been used as a wiring device that is fixed outdoors, such as an automatic blinker for a security light or a street light.

However, in the wiring device having this configuration, since the joint surface 6 between the body 1 and the cover 3 has a simple structure, water and dust may penetrate into the wiring device through the joint surface 6.

Water and dust that have entered the interior not only cause the wiring equipment to malfunction, but also may destroy electrical and electronic components such as internal circuits.

[Purpose of the invention]

The object of the present invention is to provide a wiring device that prevents accidents and breakdowns because it is difficult for water and dust to enter, and in which a cover and a body are firmly joined.

[Disclosure of the invention]

In order to achieve the above object, the present invention provides a wiring device that includes a body that houses an internal circuit and other parts, and a cover that covers the body, and the connection between the two is made at their respective peripheral walls. In the joint surface of both,
A fitting structure is formed consisting of a groove provided on the peripheral wall that will be the upper side when installed, and a first rib provided on the peripheral wall that will be the lower side when installed. The gist of the wiring device is that a second rib inscribed in the peripheral wall of the wiring device is provided over the entire circumference of the lower peripheral wall.

The following is the first part describing this invention and one embodiment thereof.
This will be explained based on the diagram. This example is an automatic flasher LE
E switch).

In normal use, the body 1 is fixed to construction materials or the like by means of metal fittings 2, and a cover 3 is joined to the lower side thereof. Inside the body 1, an internal circuit 4 and other electronic and electrical components 5 are housed.

A continuous groove 7 is provided on the joint surface 6 of the body 1 with the cover 3 with its opening facing downward, and the cover 3
is provided with a continuous first rib 8 at a position corresponding to the groove 7, and the body 1 and the cover 3 are provided with a groove 7 and the first rib 8 provided at the joint portion thereof. They are joined and fixed by forming a fitting structure in which they are fitted into each other.

In the wiring device of the present invention, it is possible to achieve fixation between the body 1 and the cover 3 using only the fitting structure shown above, but as in the embodiment shown in the figure, the side surface of the groove 7 By providing a fitting locking means consisting of a recess 9 and an engaging protrusion 10 fitted into the recess 9 on the side surface of the first rib 8, the body l and the cover 3 can be more firmly fixed. be able to.

The cover 3 is provided with a continuous second rib 11 on the inside of the first rib 8 over the entire circumference of the peripheral wall of the cover 3. When the body 1 and the cover 3 are joined, this second rib 11 The rib 11 is now inscribed with the peripheral wall of the body 1 without any gaps.

The first rib 8 and the second rib 11 are provided at the joint between the body 1 and the cover 3, and most of the water and dust that have entered this joint are absorbed by the double ribs. Since the above infiltration is prevented, accidents and malfunctions caused by infiltration of water and dust into the inside of the wiring device can be reduced.

The conventional electronic switch has a body 1 as shown in Figure 2.
Since the outer surfaces of the cover 3 and the cover 3 were uneven near the joint surface 6, it was not only unsightly, but also had the possibility that the cover 3 would easily come off if something came into contact with the uneven protrusions. In this regard, at the joint between the body 1 and the cover 3 in this embodiment, means related to the joint, such as ribs and grooves, are not exposed to the outside, and this alone improves the appearance. If the outer surfaces of the body 1 and the cover 3 are flush with each other at their joints as in the embodiment shown in the figure, the appearance will be even better.
Since there is no protrusion at the joint between the cover 3 and the cover 3, there is no fear that the cover 3 will come off from the body 1 due to contact with an object.

In the groove 12 between the first rib 8 and the second rib 11,
A space is provided between the bottom surface and the joint surface 6 of the body fitted into this groove 12, and by providing a notch in a part of the first rib 8 that forms this groove 12, At least the bottom of this space is open to the outside of the wiring device.

Although this space and the notch in the first rib 8 are not necessarily necessary in the wiring device of the present invention, if a space is provided at the bottom of the groove 12, the capillary beyond the first rib 8 can be formed. Intrusion of water due to this phenomenon can be prevented in this space, and if the first rib 8 is cut out, water and dust in the groove 12 can be constantly removed to the outside of the wiring device. The effect can be further enhanced.

In the wiring device of the present invention, if the member on the upper side of the joint is provided with the groove 7 and the member on the lower side is provided with the two ribs 8 and 11 in its normal use state, whichever of the upper and lower members has the internal Although circuits, etc. may be housed therein, it is better to have the member (body) housing the internal circuits, etc. on the upper side with its opening facing down, as in the embodiments shown above, so that the cover 3 can be closed after installation. Even if the device is lost, the internal circuits etc. can be protected from the rain by the body 1, and since rainwater does not accumulate inside the body 1, it is possible to reduce accidents caused by rainwater.

〔Effect of the invention〕

The wiring device according to the present invention is constructed as described above, and is firmly joined by the double rib provided at the joint and the groove fitted into it, and water and dust do not escape from this joint. Since it is difficult for the metal to penetrate, accidents and failures do not occur, and the appearance can be improved because the means related to joining are not exposed to the outside.
