Description

本発明は、電子機器を収納する電子機器収納箱に関し、特に、保守点検時等における脱着作業を容易に行うことができ、小型かつ軽量の電子機器収納箱に関する。   The present invention relates to an electronic device storage box for storing electronic devices, and more particularly, to a small and lightweight electronic device storage box that can be easily attached and detached during maintenance and inspection.

従来、建物の屋外壁面等から突出するように設置された電子機器収納箱に収納された電子機器を保守点検する際、または電子機器に障害が発生した場合には、例えば、図６に示すように、コインロック式鍵３５を開き、電子機器３３を電子機器収納箱３１の前面から取り外したり、取り付けたりする必要がある。その際、電子機器収納箱３１の内部へ水が侵入するのを防止するため、電子機器収納箱３１の前面部には、防水用パッキン３１ａと、この防水パッキン３１ａに当接する枠部３２ａ及び蝶番３４を有し、開閉可能で、機器前面を透視することのできる前面扉３２が設けられる（例えば、特許文献１）。   Conventionally, when an electronic device stored in an electronic device storage box installed so as to protrude from an outdoor wall surface of a building is inspected or when a failure occurs in the electronic device, for example, as shown in FIG. In addition, it is necessary to open the coin lock type key 35 and remove or attach the electronic device 33 from the front surface of the electronic device storage box 31. At this time, in order to prevent water from entering the inside of the electronic device storage box 31, a waterproof packing 31a, a frame portion 32a that abuts against the waterproof packing 31a, and a hinge are provided on the front surface of the electronic device storage box 31. A front door 32 that is openable and closable and that allows the front of the device to be seen through is provided (for example, Patent Document 1).

さらに、この電子機器収納箱３１は、上記防水構造に加え、電子機器の内部発熱による温度上昇を防止するための空冷対策として、電子機器の外形容積に比較して電子機器収納箱の内部容積を大きく確保することにより、対流、放射等にて放熱する構造を採用している。   Further, in addition to the waterproof structure, the electronic device storage box 31 has an internal volume of the electronic device storage box that is larger than the external volume of the electronic device as an air cooling measure for preventing temperature rise due to internal heat generation of the electronic device. A structure that dissipates heat by convection, radiation, etc. is adopted by ensuring a large amount.
