Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for draining water or juice (hereinafter referred to as water) from a gap between a cover glass and a case in a case of a vehicle-mounted instrument.

[0002]

2. Description of the Related Art In recent years, among in-vehicle instruments, in particular, a clock has been rapidly switched from analog display to digital display. For this reason, there are many electronic components, and failures such as short circuits in the circuit due to dirt and water are increasing. For example, in an automobile watch, as shown in FIG. 2, the cover glass 2 is formed into a concave curved shape, and the lower end 4 is disposed above the bottom surface 8 of the case 6.

[0003]

When a considerable amount of water or the like accidentally splashes on the entire surface of the cover glass during cleaning or eating and drinking in the vehicle, the water or the like may cause the cover glass 2 and the glass retainer 10 of the case 6 to fall. It was easy to get inside the case from the gap. Water that has entered the case is left in the case without being drained.For example, when the temperature inside the vehicle becomes high, moisture evaporates, which causes moisture to adhere to the electronic components inside the case. , A failure occurred due to short circuit or corrosion of the circuit. An object of the present invention is to provide a case capable of appropriately discharging water or the like entering the case with a very simple configuration.

[0004]

In order to achieve the above object, according to the present invention, a water drop guide path is provided below the glass presser and on the front surface of the cover glass, and is inclined downward from above. It is arranged right above the drain hole provided on the bottom surface.

[0005]

1 is a sectional view of a main part of a case according to the present invention. A drain hole 12 is provided on the bottom surface of the front case 10, and the cover glass 14 includes a curved portion 16 and a flat plate portion 18. The front surface of the flat plate portion 18 is inclined from upper left to lower right over the entire lateral width. A water drop guide path 20 is provided. The lowermost position of the curved portion of the cover glass 14 is pressed and fixed to the glass holder 22 of the front case 10. Although not shown, the cover glass 14 is fixed to the front case 10 with screws inside the front case 10.

[0006] With this configuration, water or the like 30 that has entered the inside of the case from the gap between the cover glass 14 and the glass presser 22 of the front case 10 is guided to the water droplet guide path 20 and is drained.
2 and is discharged out of the case by natural fall. In the present embodiment, the water drop guide path 20 is constituted by a single protrusion, but this may be a groove.

[0007]

According to the present invention, water or the like entering through the gap between the cover glass and the glass press of the case is drained from the bottom of the case by a water drop guideway provided below the glass press and in front of the cover glass. Since the water is reliably discharged from the holes, the situation in which water or the like entering the case is left as it is as in the past is eliminated, and moisture adheres to the electronic components located inside the case even when the temperature inside the vehicle becomes high. As a result, it is possible to greatly reduce the occurrence of short circuit and corrosion of the circuit. In addition, since the configuration is extremely simple, it is expensive. Further, it is possible to significantly suppress the fogging of the cover glass due to water vapor, and to provide a safe in-vehicle instrument.
