Therefore, according to this invention, the protrusion amount of the sensor and the cover with respect to the wall surface can be made small.

〔Example〕

 Hereinafter, the wall mount type detector according to the present invention will be described in detail.

FIG. 2 is an exploded perspective view showing an embodiment of this wall-mounted detector. In the figure, 11 is a commercially available outlet box (or switch box), 12 is a commercially available mounting bracket, 13 is a connector block unique to this application, 14 is a commercially available plate, 15 is a commercially available decorative plate, and 16 is unique to this application. It is a cover.

FIG. 1 is a cross-sectional plan view of a main part showing how the wall-mounted detector 100 is mounted on the wall surface 3. Connector block 13
Is an element bracket 13-2 formed by mounting and fixing the sensor 13-1 as shown in the partially exploded cross-sectional plan view of FIG.
And the housing 13-3 combined with the element bracket 13-2. The combination state of the element bracket 13-2 and the housing 13-3 is from the both sides of the connecting brackets 13-4, 13 It is fixed by attaching -4. Then, the connector block 13 is attached to the mounting bracket 12 by using the connecting fittings 13-4, 13-4. On the other hand, the cover 16 is composed of a cover bracket 16-1 formed in a substantially U-shaped cross section and a decorative cover 16-2 whose peripheral surface is inclined inward. 2 is screwed to the cover bracket 16-1.

The element bracket 13-2, the housing 13-3, the cover bracket 16-1 and the decorative cover 16-2 are made of ABS resin. The element bracket 13-2 has silver plated on the entire front and back surfaces,
Lead wires 13-11 to 13-13 are led out from -1, and Faston terminals 17-1 to 17-3 with an insulating sleeve are connected to the ends thereof. Further, the cover bracket 16-1 of the cover 16 is the fourth
It is shaped like the perspective view in the figure, and has large air vents 16-11 and 16- on both sides 16-1L and 16-1R.
12 are formed. And this both sides 16-1L and 1
The tip side portions 16-13 and 16-14 of the 6-1R have a latch shape, and the latch portions 13-11 and 13-12 engaging with the tip side portions 16-13 and 16-14 are the housing 13 -3 is formed on the inner surface side (see FIG. 3). That is, by engaging the tip side portions 16-13 and 16-14 of the cover bracket 16-1 with the latch portions 13-11 and 13-12 of the housing 13-3, the cover 16 is attached to the connector block 13. The cover 16 is moved in the front-back direction by, for example, the side portion 16-1 of the cover bracket 16-1.
By pressing L with a flat-blade screwdriver or the like in the direction of the arrow shown in FIG. 4 (FIG. 4), the elasticity can be utilized. In this example,
In order to prevent the cover 16 from being removed by an unspecified number of people, the set screw 18 is tightened from the side of the housing 13-3.

Next, features of the wall-mounted detector 100 configured as described above will be described.

That is, according to the wall-mounted detector 100 according to the present embodiment, as is apparent from the figure, the amount of protrusion of the sensor 13-1 and the cover 16 from the wall surface 3 is small, and the size and thickness are reduced. is made of. Further, in terms of indoor design, even if it is provided with a lighting switch or the like, it is well balanced, does not impair the aesthetic appearance of the wall surface 3, and is not an obstacle. In addition, commercially available parts (outlet box 11, mounting bracket 1
2, the plate 14 and the decorative plate 15) are effectively used, and the total cost reduction can be promoted. The decorative plate 15 may be newly manufactured.

Further, in terms of performance, by moving the cover 16 in the front-back direction (see FIGS. 5 (a) and 5 (b)), the gap h between the cover 16 and the decorative plate 15 is 5 to 10 mm.
Can be adjusted freely within the range of
The amount of ventilation to 13-1 can be adjusted in multiple stages. Therefore, by appropriately adjusting the gap h according to the wind speed of the mounting location, it is possible to secure an appropriate amount of ventilation to act on the sensor 13-1, and the cover 16 pops out from the wall surface 3. You will be able to minimize the amount. In addition, the following effects (1) to (4) can be obtained by adjusting the gap h to give as much air flow as possible to the sensor 13-1.

 Response speed becomes faster.

The influence of heat radiation from the surroundings can be reduced.

 Has a heat dissipation effect such as self-heating.

In the above description, the airflow is taken into the sensor 13-1 smoothly along the inclined shape because the peripheral surface of the decorative cover 16-2 is inclined inward. In addition, at this time, since the ventilation port is secured in the cover bracket 16-1 in a shape close to the entire circumference, it is possible to cope with the vertical and horizontal air flows. On the other hand, in the conventional detector, as shown in FIG. 7, there is a drawback that the resistance at the ventilation port 2-1 is large and the air flow is difficult to enter.

Further, in the present embodiment, heat radiation to the sensor 13-1
The structure has reduced heat conduction. That is, since the entire front and back surfaces of the element bracket 13-2 are silver-plated, heat radiation from the outside is reflected by this silver-plated portion, and heat radiation to the sensor 13-1 is reduced. Becomes Further, since the housing 13-3 is interposed between the element bracket 13-2 and the bracket 12,
The housing 13-3 serves as a heat insulator and reduces heat conduction to the sensor 13-1. That is, with respect to the heat conducted to the bracket 12 by the conduit tube (not shown) and the switch box 11, the housing 13-made of ABS resin is used.
3 serves as a heat insulator and reduces heat conduction to the element bracket 13-2. Then, most of the heat conducted to the element bracket 13-2 is dissipated by the silver plating, so that the influence of heat conduction to the sensor 13-1 is almost eliminated. And such a sensor 13
The structure for reducing the heat radiation and heat conduction to -1 greatly contributes to the realization of the wall mount type detector 100 that is small and thin. That is, in the conventional detector, as can be seen from FIG. 7, in order to reduce the influence of the heat radiation from the wall surface 3, the detecting end 1 is devised so as to be separated from the wall surface 3. However, it was difficult to reduce the thickness. On the other hand, in the present embodiment, by adopting the structure for reducing heat radiation and heat conduction as described above, the desired performance can be ensured even if the connector block 13 is incorporated in the outlet box 11. Is made.

Further, in this embodiment, the cover 16 has a feature that the shape of the decorative cover 16-2 can be freely changed. That is, the decorative cover 16-2 is removed from the cover bracket 16-1 and, for example, FIGS.
It is possible to replace it with a decorative cover having a different shape as shown in (4), and it is possible to easily cope with diversification of designs according to customer's request. Also, FIG. 6 (d)
As shown in FIG. 5, the air permeability can be further improved by forming a large number of holes on the surface.

Incidentally, in the above embodiment, the element bracket
Although 13-2 is silver-plated, the silver plating is not limited to silver, and various platings can be applied as long as they can reflect heat radiation. Further, in the present embodiment, the cover 16 and the connector block 13 are coupled by the latch method, but if the screwing method is adopted, the gap h can be adjusted steplessly. It can be said that the method is more advantageous.

[Effect of device]

As described above, according to the wall mount type detector of the present invention, the connector block on which the sensor is mounted is detachably mounted in the box embedded in the wall surface.
Since the cover capable of adjusting the ventilation area to the sensor is arranged on the front surface of the connector block, the protrusion amount of the sensor and the cover with respect to the wall surface can be made small, and the aesthetic appearance of the wall surface may be spoiled. It does not get in the way, and has various excellent effects.
