Description

  Embodiments described herein relate generally to an electronic device casing.

  When installing an electronic equipment housing with electronic equipment inside, when water enters the housing by opening / closing the housing in rainy weather or when water droplets are generated in the housing due to condensation In order to prevent a short circuit from occurring in the device in the housing due to the water, a water drain hole is provided on the bottom surface of the housing to prevent water from collecting in the housing.

  In a case of an electronic device, a partition such as a shelf is provided inside the case, and the inside of the case is divided into several rooms. In this case, if water is not moved to the bottom surface of the housing provided with the water drain hole, there is a problem that water accumulates in the housing.

  Therefore, when the interior of the housing is partitioned into a plurality of rooms, a drain hole is provided on the bottom surface of each room. In this case, when water moves from the drain hole on the bottom surface of the upper room to the lower room, the water that moves from the drain hole on the bottom surface of the upper room to the lower room jumps. Care must be taken not to cause a short circuit.

  For example, the water generated in the uppermost room cannot be discharged outside the casing unless the water moves to the lowermost room having a drain hole that leads to the outside of the casing. When water moves, the water moved to the lower room from the drain hole on the bottom of the uppermost room touches the device installed in the lower room so that it does not short circuit. It is necessary to consider.

  Moreover, in an electronic device housing, there is a case where the operation of an electronic device installed in the housing is not stopped by switching to an auxiliary power source in the event of a power failure. In such a case, for example, a lead storage battery that generates hydrogen during charging may be installed as an auxiliary power source in the housing. In this case, in addition to providing a vent hole in the room where the lead-acid battery is installed, it is necessary to isolate the room where the lead-acid battery is installed from the other room so that the generated hydrogen does not flow into other rooms and become full. is there.

  However, when the interior of the enclosure is divided into multiple rooms, it is necessary to move the water to the bottom of the lowermost room in order to drain water in each room. Each room needs to be connected to the bottom. For this reason, it is difficult to provide a room that is isolated from other rooms inside the case, so the degree of freedom of layout in the case is low, and a lead storage battery that generates hydrogen during charging is installed in the case as an auxiliary power source. It was difficult.

  The present embodiment has been made paying attention to the above circumstances, and is to provide an electronic device casing that can discharge water from each room in the casing and can increase the degree of freedom of layout in the casing. is there.

The embodiment partitions the interior of the housing into a plurality of rooms at least in the vertical direction, partitions the upper and lower rooms of the housing body, and is in contact with the side walls of the housing body in a fixed partition portion, the formed while straddling between the partition portion of the side wall of the housing body and the upper room of the partition portion corresponding to those in the room of the lower, the upper And a drain hole for draining the room water .

  FIG. 2 shows a drain hole 8 between the first room 2a and the second room 2b. This drain hole 8 is formed in an elongated round hole shape that is long in the vertical direction. Furthermore, the drain hole 8 is formed in a state straddling the upper and lower rooms of the partition part 3 as shown in FIG. The drain hole 8 is closed by the bent portion 5 of the shelf board 4 at the opening portion on the side of the room (second room 2 b in FIGS. 2 and 3) below the partition 3. Thereby, the water inside the first chamber 2a can be drained to the outside of the housing body 1a from the drain hole 8 between the first chamber 2a and the second chamber 2b. Similarly, the water inside the second chamber 2b can be drained to the outside of the housing body 1a through the drain hole 8 between the second chamber 2b and the fourth chamber 2d. Further, the water inside the third chamber 2c can be drained to the outside of the casing body 1a through the drain hole 8 between the third chamber 2c and the fourth chamber 2d.

  In the present embodiment, an example of the drain hole 8 having an oblong hole shape is shown. However, the shape of the drain hole 8 is not limited to this, and may be a round shape, a rectangular shape, a slit shape, or the like. Good. Further, the number of drain holes 8 may be one in each room, or a plurality of drain holes 8 may be formed as necessary.

  Further, as shown in FIG. 4, the lowermost chamber (the fourth chamber 2 d in the present embodiment) of the housing body 1 a is an L-shape formed at the joint between the floor surface 9 and the side wall 6. The drain hole 8 is formed by the notch 10. And the water inside the 4th room 2d can be drained from the drain hole 8 between the floor surface 9 and the side wall 6 to the exterior of the housing body 1a.

In the electronic device casing 1 according to the present embodiment, the side wall 6 of the casing body 1a corresponds to the partition 3 between the upper and lower rooms, that is, between the first room 2a and the second room 2b. A drain hole 8 for draining the upper room is formed between the second room 2b and the fourth room 2d and between the third room 2c and the fourth room 2d. Thereby, even if the inside of the housing body 1a is divided into a plurality of rooms by the partition part 3, the water inside each room can be drained directly from the drain hole 8 of the side wall 6 of each room. Therefore, when draining the water in the upper room of the casing main body 1a, it is not necessary to pass through the lower room, so that the water that has moved from the upper room to the lower room is in the lower room. The risk of a short circuit can be eliminated by touching the device installed in the.

  The drain hole 8 is formed so as to straddle between the upper and lower rooms of the partition part 3, and the drain hole 8 is a room below the partition part 3 (second room 2b in FIGS. 2 and 3).
