An electronic device includes a rack, a mount housing in which an electronic component is housed, and mounted in the rack from a front face side or rear face side of the rack, and a movable duct configured to have a housed state where the movable duct is retracted from an opening formed in a sidewall part of the mount housing and is housed in the mount housing and an opened state where the movable duct is moved to outside of the mount housing through the opening so as to form a ventilation flue located outside the mount housing and communicating with the opening.

Electronic device

An electronic apparatus installed outdoors includes a cabinet body having an opening that houses components constituting the electronic apparatus, a lid body that closes the opening, a printed circuit board unit on which electronic components are mounted, and a block made from an opaque material that has a plurality of holes and is disposed between the printed circuit board unit and the lid body. The printed circuit board unit has a plurality of LED's that indicate operating states of the electronic apparatus. The lid body has a window portion covered with a transparent material having a larger area than a region where the LED's are arranged, so that the window faces the region. The block is disposed so that light emission from the plurality of LED's can be observed from the outside of the electronic apparatus through the respective plurality of holes and the window portion.

The present invention relates to a breaker apparatus and breaker unit. The breaker apparatus comprises a breaker unit including a power supply/cut-off breaker part, a power connecting part, a first unit connecting part, a ground connecting part and a second unit connecting part and further comprises a breaker unit mounting board including a mating power connecting part, a mating ground connecting part, a first connection mediating part and a second connection mediating part. This breaker apparatus is capable of constituting a power distributing apparatus with a necessary but minimized construction, and of extending the breaker unit in a minimum unit according to necessity. In addition, with this breaker apparatus, parts can be used in common irrespective of a change of a ground system, and further, can be replaced in the hot-line condition without cutting off the power supply to a system.
