Description

  The present invention relates to a cabinet for electrical and electronic equipment having a frame structure.

2. Description of the Related Art Cabinets for electrical and electronic equipment in which side plates, doors, and the like are attached to the opening frame portion on the side surface of a frame assembled into a square frame shape are widely used. In such a cabinet, since the side plate is firmly fixed to the frame, the side plate serves as a reinforcing member, and it is possible to prevent the frame structure from being distorted to some extent against earthquake shaking. Furthermore, there is also known one in which a brace is inserted in the side opening frame for seismic reinforcement (see, for example, Patent Document 1).
All of these are effective when they are shaken in parallel with the surface on which the side plates of the cabinet are provided due to an earthquake.

However, the opening frame that can be opened and closed by the door, such as the front and back of the cabinet, is opened completely so that it will not become an obstacle to the work when the rack unit is installed and maintenance is performed. It was necessary to be able to reinforce by bracing. In addition, since one end side of the door is merely linked by a locking device, the effect of reinforcing the opening frame by the door cannot be expected like a side plate, so the cabinet is parallel to the surface on which the door is provided due to the earthquake. When it sways, it is difficult to prevent distortion of the frame structure, and there is a problem that the seismic strength of the entire cabinet is deteriorated.
Japanese Patent Laid-Open No. 9-321452
