A power supply board includes: a first board including a top surface on which a processor is capable of being mounted, a bottom surface located on an opposite side of the top surface, and a plurality of first through holes and a plurality of second through holes capable of being electrically connected with the processor by penetrating through the first board from the top surface to the bottom surface; a second board arranged at a position distant from the bottom surface of the first board and provided with a power supply device; a first conductor mounted on the bottom surface of the first board and electrically connects the plurality of first through holes and the power supply device, and a second conductor mounted on the bottom surface of the first board and electrically connects the plurality of second through holes and the power supply device.

Power supply board

An electronic device unit includes a frame member, a first board that is retained so as to be capable of moving with respect to the frame member in a horizontal direction of the frame member within a range restricted by a movement restricting portion, a first connector provided to the first board, a second board that faces the first board in the horizontal direction and that is positioned with respect to and fixed to the frame member; and a second connector that is provided to the second board and that is connected to the first connector in the fixed state of the second board.

Electronic device unit and electronic device

The removing jig includes a frame member and an arm member. The arm member includes a pair of side plates each provided with an axial hole. The arm member further includes an engagement portion that engages with the lever portion at its tip. The frame member includes a contact portion that contacts with a back surface of the connector body, a pair of side frame plates each provided with a guide groove formed with respect to the axial hole, and a first window portion from which the engagement portion protrudes.

Connector removing jig and connector removing method using the same

An electronic apparatus includes: a first connector; a second connector; a first electronic unit connectable to the first connector; a second electronic unit connectable to the second connector; and a printed circuit board that includes the first connector and the second connector between a first extended center line toward a unit board of the first electronic unit and a second extended center line toward a unit board of the second electronic unit on a first side of the printed circuit board when the first and second electronic units are connected to the first and second connectors, respectively.

Electronic apparatus

An electronic device includes: a chassis for housing an electronic unit; and a hold member capable of holding to a fan unit blowing air toward the electronic unit and attachable to and detachable from a plurality of positions of the chassis.

Electronic device

An apparatus has a plurality of printed board units each including a printed board, a frame to have the printed board arranged therein, a first rail to be arranged at a first lower end of an inner wall of the frame having the printed board located thereon in a lower opening of the frame, and a second rail to be arranged at a second lower end opposed to the first lower end in the opening; a housing including a rail holding unit to movably hold the first rail of a first printed board unit and the second rail of a second printed board unit adjacent to the first printed board unit among the plurality of printed board units; and a cooling fan to be arranged on an upper side or underside of the housing to send air into the frame.

Apparatus, mounting structure, and mounting method

In a structure in which racks back-to-back with each other are placed on a floor, a bottom of at least one of the racks is pressed against the floor by a connecting bar crossing the bottom. In a structure in which a cover is mounted on a rack, a cover has a first shaft movable in a direction parallel to the first shaft and the cover is mounted on the rack by using the first shaft. In a structure in which a cable rack is mounted on a top surface of a rack, a plurality of engagement screws provided on the cable rack are driven into holes formed on the top surface of the rack so that the cable rack is mounted on the top surface of the rack.
