Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.
The cable holding member of the present invention is used for collecting a large number of cables drawn from a device unit such as a communication device housed in a rack. FIG. 9 shows, as an example, a case where the splice unit 22 is attached to the mount frame 21 of the rack 20, and a plurality of cables 23 pulled out from the front surface of the splice unit 22 are connected to a plurality of cable holding members. It is structured to be used and put together. The cable 23 is an optical cable.

  As shown in FIG. 10, a panel 24 is mounted adjacent to the splice unit 22 in the vertical direction. The panel 24 is provided with a required number of cable holding members for holding the cables 23 together. 10, a plurality of cable holding members are arranged at predetermined intervals in the horizontal direction in parallel with the front surface of the splice unit 22. In the drawings, reference numeral 1 denotes a holding member main body, and 30 denotes a cover that covers an end of the cable holding member.

  As shown in FIGS. 1 and 2, the holding member main body 1 includes a pair of upper and lower arms 3, 3 for holding the cable 23. The arms 3 are formed so as to project in the horizontal direction from the upper and lower ends of the base 2 of the holding member body 1.

  A fixing portion 5 having a flat fixing surface 4 for attaching the holding member main body 1 to the panel 24 is formed on the back surface side of the base portion 2 (in the direction opposite to the direction in which the arm portion is extended). . The fixing part 5 includes a toolless fixing part 8 that can be fixed without a tool when the holding member main body 1 is mounted on the flat panel 24, and a mounting frame 21 with screws when the mounting member 21 is mounted on the mounting frame 21. The screw fixing portion 7 which can be fixed to the fixing hole 31 formed in the above is formed. Thereby, as a mounting means of the holding member main body 1, both the screw fixing portion 7 and the toolless fixing portion 8 can be adapted.

The screw fixing portion 7 is formed at the center of the fixing portion 5 and the base 2 so as to penetrate the fixing portion 5 and the base 2. In addition, the screw fixing portion 7 is formed in a shape in which the upper end and the lower end of the fixing portion 5 are cut out in a semicircular shape.
Further, as shown in FIG. 12, a plurality of holding member main bodies 1 can be vertically stacked, and adjacent holding member main bodies can be connected to each other by a connecting member 32. The connecting member 32 is entirely formed of a substantially rectangular plate-like body, has a screw fixing portion 33 formed in the center, and has upper and lower portions as insertion pieces 34, 34, respectively. The insertion piece 34 is inserted into guide holes 35 formed at the upper and lower ends of the base 2 of the holding member body 1 to firmly connect adjacent holding member bodies. Thereby, the holding member main body 1 can be vertically stacked and expanded according to the use situation.
Since the holding member main body 1 is formed to have the minimum width (one unit) of the device unit, the cable 23 may be wired from the horizontal to the vertical through the arm 3 for each unit. The required number of holding member main bodies 1 may be used by being connected in the vertical direction.
The screw fixing portion 33 of the connecting member 32 matches the screw fixing portion 7 formed at the upper and lower ends of the fixing portion 5 when the holding member main bodies are connected to each other, so that both can be fastened with one bolt. It is configured. As shown in FIG. 13, for example, when four holding member main bodies 1 are connected, the screw fixing of the uppermost and lowermost holding member main bodies 1 can be performed without bolting all the screw fixing portions. If only the portion 7 is fastened with the bolt 6, the holding member main bodies 1 in the second and third stages located in the middle are firmly connected and fixed by the interposition of the connecting member 32 without screwing. The number of places to be fixed can be greatly reduced, and workability is improved.
Further, since the fixing surface 4 is formed flat, it is possible to fix the cable holding member to the flat surface of the mount frame 21 with screws.

Hereinafter, a case of attachment using the toolless fixing portion 8 will be described.

Is formed with a narrow hole 25b having a small width, and a protruding portion 26 is provided outside the intermediate hole 25c.

  With this configuration, the fixing portion 5 of the holding member main body 1 is horizontally pushed into the wide hole 25a and the intermediate hole 25c of the hole 25 of the panel 24 (see FIGS. 6 and 7). Next, when the holding member main body 1 is slid downward, the edge of the narrow hole 25b is inserted into the groove 9 to securely fix the panel 24. During sliding movement of the lock portion 10 downward, the lock portion 10 is pushed by the protruding portion 26 and contracts in the direction of reducing the diameter, and moves smoothly. As a result, the upper end of the lock portion 10 is engaged with the protrusion 26 protruding from the outside of the panel, thereby preventing the holding member main body 1 from falling out of the panel 24 (see FIG. 5). reference).

  As is clear from the above description, in the cable holding member of the present invention, a fixing portion having a flat fixing surface is formed on the holding member main body, and the holding member main body is formed on a flat panel in this fixing portion. A tool-less fixing part that can be fixed without a tool when mounting, and a screw fixing part that can be fixed to a fixing hole formed in the mounting frame with a screw when mounting on the mounting frame are formed. As the mounting means, both the screw fixing and the toolless fixing can be supported. Further, in the case of tool-less fixing, it is possible to easily and reliably mount the apparatus with a one-touch method without using a tool such as a screwdriver.
