There is a case. In such a case, in the patch panel described in Patent Document 1 described above, the patch panel is temporarily removed from the rack and wiring work is performed. Therefore, when the patch panel is removed from the rack, an excessive force (pull force, etc.) may be applied to the patch panel. In this case, a load is applied to the existing communication cable, and the connector is damaged or the communication cable is disconnected. It can happen. It is difficult to specify a damaged or disconnected part from a plurality of connectors and communication cables, and as a result, it may take a long time to restore the system.

  In order to eliminate the need for additional communication cables, it may be possible to wire all communication cables that can be connected to the back of the patch panel in advance. In this case, a simplified LAN wiring system is constructed. In some cases, many communication cables are not necessary and wasteful, and the cost of the LAN wiring system is increased, which is not realistic.

  An object of the present invention is to provide a patch panel fixing device capable of efficiently managing and installing a communication cable by suppressing a load on the communication cable.
