A fall prevention plate (fall prevention member) 4b and a guide member 4c that can be slid into the guide groove 5a of the R guide 5 are provided.

  The fall prevention plate 4b is provided at an end opposite to the end of the mounting plate 4a facing the device and substantially perpendicular (Z-axis direction) to the end opposite to the node 3. Yes. The fall prevention plate 4b is provided to prevent the optical cable placed on the placement plate 4a from falling, and may be configured as a single plate, or comb teeth having a gap at an arbitrary interval. It may be formed of a shaped member. Any configuration may be used as long as the optical cable is not dropped.

  The guide member 4c is provided at both ends in the longitudinal direction (X-axis direction) of the mounting plate 4a, and is fitted into the guide groove 5a of the R guide 5 so as to be slidable in the Y-axis direction.

  The R guide 5 slidably moves the mounting member 4 between the fixing position of the mounting member 4 with respect to the node 3 and the attachment / detachment position at both ends in the longitudinal direction of the mounting plate 4 a of the mounting member 4. It comes to support.

  The R guide 5 is provided for each node 3 on each of the pair of support columns 2. Specifically, the R guide 5 is attached to the R guide attachment surface 2b of the support column 2, and includes the above-described guide groove 5a, fall prevention member 5b, and screw hole 5c. Each of the pair of R guides 5 is a columnar member having a curved surface on the side opposite to the side facing each other. That is, the R guide 5 has a surface 5d that is a curved surface having a predetermined curvature on an extension line in the longitudinal direction of the mounting surface of the mounting plate 4a. That is, the surface 5d of the R guide 5 is an R surface having a predetermined radius.

  The guide groove 5a extends along the Y-axis direction, and the guide member 4c of the mounting member 4 described above is engaged to support the mounting member 4 so as to be slidable in the Y-axis direction. ing.

  The fall prevention member 5b is a protruding member that slightly protrudes from the surface 5d of the R guide 5 toward the outside in the X-axis direction, and prevents the optical cable disposed along the surface 5d from dropping forward. It has become. In addition, although the formation position and formation number of the fall prevention member 5b are not specifically limited, in order to prevent the fall of an optical cable more reliably, you may form multiple. In addition, in the state where the three cabinets 11 are arranged side by side in the left-right direction as shown in FIG. 1, each of the adjacent cabinets 11 protrudes toward the boundary portion of the adjacent cabinets 11. The fall prevention members 5b are provided apart from each other without contact. Also by this, it is possible to prevent the optical cables from dropping out of the cabinets of each other.

  Here, as shown in FIG. 3, the mounting member 4 and the R guide 5 are fixed by a screw 7 through a screw hole 4 d of the guide member 4 c and a screw hole 5 c of the R guide 5. In this fixed state, as shown in FIG. 3, the surface of the mounting plate 4a of the mounting member 4 and the surface 5d of the R guide 5 form the same surface without a step. As a result, the optical cable placed on the placement plate 4a of the placement member 4 is guided downward by the R guide 5 without stress, without being affected by a step or the like.

[Depth when mounting member 4 is fixed]
FIG. 4A shows a state in which the cable 8 is connected to one node 3 as viewed from above. FIG.4 (b) is a figure which shows an AA arrow end surface in Fig.4 (a).

  As shown in FIG. 4A, the node 3 includes a cable 8 connected to each connection terminal 3b formed on the terminal forming surface 3a, and an R guide 5 along the mounting plate 4a of the mounting member 4. Although not shown, at least some of the plurality of cables 8 are guided in the direction of the R guide 5 while being guided by the fall prevention plate 4b.

  Here, as shown in FIG. 4B, the mounting member 4 is substantially parallel to the cables 8 protruding from the connection terminals 3b so that the cables 8 connected to the connection terminals 3b can be mounted without stress. It is fixed to the R guide 5 so that it can be mounted on the mounting surface of the mounting plate 4a. That is, if the placement surface of the placement plate 4a is higher than, for example, each connection terminal 3b with respect to the height direction of the cabinet 11, each connection terminal 3b of the cable 8 connected to each connection terminal 3b. There is a possibility that the portion close to is bent upward by the mounting plate 4a, causing cable breakage or cable damage due to the end of the mounting surface of the mounting plate 4a. However, according to the configuration of the present embodiment shown in FIG. 4B, the placement surface of the placement plate 4a is the same height as each connection terminal 3b, more specifically, in the height direction of the cabinet 11. It exists in the same height as the lower end surface of the cable 8 which protrudes in the horizontal direction from the connection terminal 3b. Therefore, it is possible to realize a mode in which the cable 8 protruding from the connection terminal 3b is placed on the placement surface of the placement plate 4a while maintaining the horizontal direction.

  Further, when the placement member 4 is in a fixed position with respect to the node 3, the placement member 4 has a side closer to the node 3 in the front-rear direction end portion to the placement member 4 of the node 3. It is formed so as to be separated from the opposing surface by a predetermined distance B. The distance B may be a distance that does not contact the connection terminal 3 b formed on the terminal formation surface 3 a of the node 3 with the end portion close to the node 3 among the end portions in the short direction of the mounting member 4. As a result, of the short-side end portions of the mounting member 4, the end portion close to the node 3 comes into contact with the connection terminal 3 b, and the cable 8 protruding from the connection terminal 3 b is stressed and has problems such as bending. Thus, the cable 8 can be placed on the placement plate 4a of the placement member 4 without stress.

  In the present embodiment, the information communication apparatus that configures the supercomputer 101 is described as an example of a device that can be connected by a cable. However, the present invention is not limited to this. Moreover, although the optical cable was demonstrated as a cable, it is not limited to this.
