  The frame-type storage box for electrical and electronic equipment forms a skeleton with a vertical frame, horizontal frame, and depth frame, houses electrical and electronic equipment inside, and is provided with open / close doors on the front and back, and the left and right sides are vertical A structure in which a side plate is attached using a side plate attachment fitting attached to a frame is common.

  The side plate is often attached by a fixture called a panel latch. The panel latch is provided on the back surface (inner surface) of the side plate, and the engaging claw is engaged with the engaging portion of the side plate mounting bracket attached to the vertical frame to fix the side plate. At this time, in order to bring the side plate into close contact with the outer surface of the vertical frame, the side plate mounting bracket needs to be arranged inside the outer surface of the vertical frame.

  When frame-type electrical / electronic equipment storage boxes are used in a data center, it is common to connect adjacent electrical / electronic equipment storage boxes. In this case, the side plates are removed, and the vertical frames of adjacent electric and electronic equipment storage boxes are fixed with a connecting metal fitting (Patent Document 1). If the connecting metal fitting is located inside the outer surface of the vertical frame, the connecting metal fittings cannot be brought into close contact with each other.

  As described above, both the side plate mounting bracket and the connecting bracket are mounted on the vertical frame of the electrical / electronic equipment storage box. However, since the mounting positions must be different, two types of mounting brackets must be manufactured. There was a problem that the number of parts increased.
