In a box in which a lid is closed via a hinge and an electronic device is housed inside, a packing member provided between the lid and a main body to be fitted and provided with waterproofness is housed. It is provided on the outer circumference of the housing of the electronic device,
It is characterized in that a ventilation hole for heat exchange and a shielding plate for covering the ventilation hole with a certain distance from the ventilation hole to provide drip-proof property are provided.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a box for accommodating electronic equipment, and more particularly to a box having excellent waterproof and drip-proof properties.

[0002]

[Prior art]

 FIG. 3 is a cross-sectional view of a conventional box body in which electronic devices are stored. In the figure, 1 is a main body in which an electronic device (not shown) is housed, 2 is a lid that is opened and closed centering on a hinge 3, 4 is packing provided between the main body 1 and the lid 2, Reference numeral 5 is a screw for fastening the main body 1 and the lid body 2. Since electronic devices are carried and used outdoors under rainfall, the screws are tightly tightened to prevent water from entering the internal electronic devices when they are carried.

[0003]

[Problems to be solved by the device]

 Such a conventional box body requires a tool for opening and closing the lid body, which is inconvenient to open and close the lid body, and has a disadvantage that the structure is large and it is inconvenient to carry. In addition, when operating the electronic device in the rain, rainwater may enter from the ventilation holes provided in the housing of the electronic device for heat exchange, which may cause a failure of the electronic device.

The present invention has been made in view of the above point, and the lid can be opened and closed without using a tool, and rainwater can be prevented from entering the electronic device even during operation in rainy weather. It is an object of the present invention to provide a box body that prevents failure of the container.

[0005]

[Means for Solving the Problems]

 In order to achieve such an object, the present invention relates to a box body in which a lid is closed via a hinge, and an electronic device is housed therein. The box is provided between the lid and a main body, and is waterproof. And a ventilation hole that is provided on the outer periphery of the housing of the electronic device that is housed therein and that exchanges heat, and the ventilation hole that has a certain distance from the ventilation hole. It is characterized by the provision of a cover and a shielding plate that imparts drip-proof property.

[0006]

[Action]

 Each component of the present invention operates as follows. The packing member is provided between the lid and the main body to prevent water from entering the box body from the outside. The ventilation hole cools the heat generated by the electronic device, so that the cooling fan sucks the outside air and releases the air that has cooled the electronic device to the outside of the electronic device. The shielding plate prevents water from entering through the ventilation hole during operation.

【Example】

 An embodiment of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a configuration diagram of a box body of the present invention, (A) is a front view, (B) is a plan view, and (C) is a side view. In the figure, 10 is a main body of a box in which electronic devices are stored, 20 is a lid that opens and closes around a hinge 21, 11 is a handle, and a belt that is held by hand or passed through is hung on the shoulder. Be carried around. The lid body 20 can be opened and closed in the arrow U direction around the hinge 21, and after being tightened, the hook lock 22 is hung on the main body 10 side.

FIG. 2 is a sectional view taken along line A-A ′ of FIG. The figure shows a state in which the lid body 20 is tightened, and during operation, the lid body 20 is opened backward from the front side of the figure. Reference numeral 12 is a power supply unit provided on the main body 10 side, 13 is a printed circuit board on which electronic components are mounted, 14 is an operation unit, and operation switches and an indicator (not shown) are provided. Reference numeral 21 denotes a packing member for imparting waterproofness, which prevents rainwater from entering the electronic device. Ventilation holes 15 and 16 are provided on the side surface of the operation unit 14, and radiate heat generated by the power supply unit 12 and the printed circuit board 13 to the outside.

Reference numeral 17 denotes a cooling fan, which sucks cold air from the ventilation hole 15 side to cool the power supply unit 12 and the printed circuit board 13 and discharges warm air from the ventilation hole 16 side to the outside. Reference numeral 18 is a shield plate for imparting a drip-proof property to the electronic device, and an opening 18a for letting air through is provided below to cover the ventilation holes 15 and 16 so that water droplets from above do not enter the electronic device.

With the box body having such a configuration, with the lid body 20 tightened, water having a diameter of 25 mm is discharged for 15 minutes at a water pressure of 1 Kgf / cm ² from obliquely above 3 m, and a good waterproof result is obtained. Has been. Also, in the experiment in which the box body was tilted 15 degrees with the lid open, and water droplets fell from the upper 30 cm to the operating part at a rate of 1 cm ³ / min for 3 hours or more, water did not enter the electronic device and was good. The result was good. Since the waterproof property is provided not only between the main body 10 and the box body 20 but also by the shielding plate 18, the box body does not need to be formed by casting as in the conventional case, and can be made inexpensive by FRP and It can be made lightweight.

[0011]

[Effect of device]

 As described above in detail, the box body of the present invention can open and close the lid without using a tool, prevent rainwater from entering the electronic device even during operation in rainy weather, and cause failure of the electronic device. There is no effect.
