Abstract: An electronic device includes an electronic component; a conductive housing that has electric conductivity and a vent port and houses the electronic component; a fan that is housed within the conductive housing; a conductive duct that has electric conductivity and couples the vent port and the fan; and a conductive partition member that has electric conductivity, is provided in an air passage of the conductive duct, and partitions the air passage along a passing direction of wind.

Abstract: 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.

Abstract: There is provided an electronic device including a terminal configured to receive power and be provided on a back surface side of the electronic device, the terminal including a hole portion configured to be concaved from the back surface side to a front surface side of the electronic device and include a first connection portion configured to be provided on the back surface side of the electronic device and include an inner circumferential surface having a female screw groove shape, and a second connection portion configured to be provided on an inner side of the first connection portion, and include an inner diameter smaller than an inner diameter of the first connection portion and an inner circumferential surface smoother than the inner circumferential surface of the first connection portion.
