Description

  The present invention relates to a rack fixing device and an electronic device.

  In recent years, with the development of an advanced information society, a large amount of data has been handled by computers, and many computers are installed in the same room and collectively managed. For example, in a data center, a large number of racks (server racks) are installed in a room, and a plurality of servers (computers) are stored in each rack. Then, jobs are distributed organically to those servers, and a large number of jobs are processed efficiently.

  The server is mounted on the rack using, for example, a pair of slide rails arranged with the server interposed therebetween. The slide rail has an outer rail fixed to the inside of the rack and an inner rail that slides along the outer rail. The server is fixed to the inner rail and can be easily pulled out of the rack by sliding the inner rail.

  By using the slide rail, the server can be easily pulled out from the rack, so that the maintainability of the server is remarkably improved.

  In a general data center, a rack called a 19-inch rack is used. In the 19-inch rack, the distance between the mounting holes provided in the left and right support columns is set to 19 inches (482.6 mm). The height of a server or other electronic device (network switch, storage device, etc.) housed in the rack is set to 1 U (1.75 inches = 44.45 mm) or a multiple thereof. For example, a rack having a height of 2 m (42 U) can accommodate a maximum of 42 1 U servers.

  Conventionally, various structures for fixing an electronic device to a panel, a mounting bracket, or the like using a spring have been proposed (for example, see Patent Documents 1 and 2).
