A mode for carrying out the invention will be shown below. As can be understood from what is shown in FIGS. 1 to 5, the cable holder 1 of this embodiment includes a mounting portion that can be used for fixing an electrical equipment storage box to a mounting bracket. This cable holder 1 includes a holder portion 11 that accommodates a cable, a first contact side 12 formed to face and abut against a first mounting surface 91 of the mounting bracket, and a first mounting surface 91 of the mounting bracket. 91 and a second contact side 13 formed to face and abut against a second mounting surface 92 that extends at right angles to the second mounting surface 91. Further, the mounting portion is provided on the first abutting side 12 or the second abutting side 13, and the vertical width of the first abutting side 12 or the second abutting side 13 is larger than the vertical width of the holder portion 11. It is formed longer than the width L1. Therefore, it is possible to provide the cable holder 1 that can suppress rotation even when a load is applied from the cable inserted into the holder part 11.

The electrical equipment storage box of the embodiment is a rack in which electronic equipment such as a server can be mounted, and is equipped with a mounting angle to which the equipment is attached and a frame member 9 that constitutes a support for the housing. . In this example, the frame member 9 that constitutes the support of the rack is a mounting fixture. As can be understood from FIGS. 4 and 5, the frame member 9 has a cylindrical shape with a plurality of bending points. The cable holder 1 is fixed to the frame member 9 so as to come into contact with a first mounting surface 91 and a second mounting surface 92 that form one of the corners. This cable holder 1 is used when it is desired to route a cable of an electronic device arranged in an electrical device storage box at a position adjacent to the frame member 9.

In the example shown in FIGS. 4 and 5, the first mounting surface 91 and the second mounting surface 92 are both surfaces extending in the vertical direction, and the first mounting surface 91 and the second mounting surface 92 form an angle of approximately 90 degrees. Eggplant. The cable holder 1 is provided with a first contact side 12 formed to face and abut against the first mounting surface 91, and also formed to face and abut against the second mounting surface 92. A second contact side 13 is provided. Therefore, the cable holder 1 can be attached so as to be in contact with the corner of the frame member 9, which is a mounting fitting, making the attachment work easier.

Further, as can be understood from FIG. 1, the first abutting side 12 and the second abutting side 13 have a vertical width L2, which is longer than the vertical width L1 of the holder part 11. L3 is formed. Therefore, even if a load is applied from the cable housed in the holder portion 11, the cable holder 1 is difficult to rotate. Note that even if only either the vertical width L2 of the first contact side 12 or the vertical width L3 of the second contact side 13 is made longer than the vertical width L1 of the holder part 11, the cable holder 1 can be configured to be difficult to rotate.

The first contact side 12 shown in FIGS. 1 to 3 includes a pair of locking claws 71 that serve as attachment parts to a mounting bracket, and a pair of operating pieces 72 for operating the locking claws 71. ing. For example, if the user applies pinching force to the pair of operating pieces 72 from above and below, the ends of the locking claws 71 can be separated from each other. Such an operation may be performed as necessary when fixing the cable holder 1 to the mounting bracket or when removing the cable holder 1 from the mounting bracket. Note that by using the locking pawl 71, it becomes possible to fix without using a fastening member such as a screw.

The second contact side 13 shown in FIGS. 1 to 3 is provided with a plurality of attachment holes 74 that serve as attachment portions to the attachment fittings. More specifically, a plurality of mounting holes 74 are provided into which fixing male screws 81 can be inserted. In this example, since two surfaces, the first abutting side 12 and the second abutting side 13, can be used for attachment to the mounting bracket, the wire entry direction and the fixing method can be changed. Note that it is not necessary to use both of the first contact side 12 and the second contact side 13 to fix the cable holder 1, and only one of them may be used for fixation. For example, when fixing the cable holder 1 to the mounting bracket using only the second contact side 13, as shown in FIG. It is also possible to just contact the surface of the second mounting surface 92 or the like.

In addition, if the configuration is such that mounting parts that can be used for fixing to the mounting bracket are provided at a position below the holder part 11 and a position above the holder part 11, a plurality of mounting parts may be provided at intervals. It is preferable because it becomes In this way, it becomes possible to more firmly fix the cable holder 1 to the mounting bracket. In this case, the vertical width of the attachment portion is longer than the vertical width L1 of the cable holder 1. In the example shown in FIG. 1, both the vertical width L4 of the attachment part of the first contact side 12 and the vertical width L5 of the attachment part of the second contact side 13 are the vertical width L1 of the cable holder 1. It will be longer than However, only one of the vertical width L4 of the attachment part of the first contact side 12 and the vertical width L5 of the attachment part of the second contact side 13 is longer than the vertical width L1 of the cable holder 1. You can make it so.

By the way, the cable holder 1 of the embodiment is constructed using a resin member. Further, the holder portion 11 for restraining the cable in the cable holder 1 is configured to have a rectangular shape in plan view. The holder portion 11 includes a locking portion 42 and a locked portion 43 that are engaged when the opening forming portion 41 through which the cable enters and exits is changed from an open state to a closed state. Note that among the four sides of the holder part 11 which has a substantially rectangular shape in a plan view when the opening forming part 41 is closed, the opening forming part 41 is located on one side that is closest to the first abutting side 12 or the second abutting side 13. It is preferable that the In this way, the opening forming part 41 can be placed near the first abutting side 12 and the second abutting side 13, which are fixed to the mounting bracket, and the opening forming part 41 can be prevented from deforming. can be suppressed.

As can be understood from FIG. 7, the cable holder 1 of the embodiment is provided with a locking portion 42 at the end of a bent portion extending in a band shape. This locking portion 42 locks with a locked portion 43 that is provided to protrude from a contact portion 14 that is L-shaped in plan view and includes a first contact side 12 and a second contact side 13. be able to. The locked portion 43 shown in FIG. 3 and the like includes a claw-shaped portion protruding inside the holder portion 11 at a position adjacent to the contact portion 14 . This claw-shaped portion can be fitted into a hole 45 provided in the locking portion 42. Further, this claw-shaped portion has a bent portion 46 whose tip is slightly bent toward the contact portion 14, and the state in which the locking portion 42 and the locked portion 43 are engaged is This is designed to prevent unintentional release.

The cable holder 1 shown in FIGS. 7 and 8 includes a third side 63, a fourth side 64, a fifth side 65, and a sixth side 66 that can be recognized in plan view. The holder part 11 of the cable holder 1 shown in FIGS. 7 and 8 has a substantially rectangular shape in plan view when the opening forming part 41 is closed. In the state where the angle is not set, the fourth side 64 and the fifth side 65 form an angle slightly larger than 90 degrees. This is to apply a biasing force so that the locking portion 42 and the locked portion 43 are difficult to be released when the locking portion 42 and the locked portion 43 are engaged with each other. In order to make this possible, the fifth side 65 is formed to expand outward from the rectangle when the opening forming part 41 is closed, but this is done during resin molding using a mold. This is made possible by manufacturing it so that it has a non-rectangular configuration.

With the configuration of the embodiment, as shown in FIG. 8, when the opening forming part 41 is closed, the locking part 42 can apply a biasing force to pull the locked part 43. Since this force is in a direction different from the attachment/detachment direction of the locking part 42 and the locked part 43, even if there is a biasing force, the state in which the locking part 42 and the locked part 43 are engaged can be maintained. I can do it. Note that, as described above, in the embodiment, since the return portion 46 is provided, it becomes even more difficult to release the engaged state of the locking portion 42 and the locked portion 43.

By the way, in the cable holder 1 of the embodiment, the fifth side 65 and the sixth side 66 are formed to have more flexibility than the other sides. In order to increase the flexibility of this portion, a hollow portion 51 extending over two sides, a fifth side 65 and a sixth side 66, is formed. By configuring the hollow portion 51 to span two sides, the sixth side 66 can easily move in the horizontal direction, and the opening of the cable holder 1 can be made wider. Further, in the example shown in the embodiment, the hollow portion 51 is formed so as to span the fifth side 65 and the sixth side 66, but it is possible to widen the opening even if this is not the case. For example, the hollow portion 51 may be formed so as to span the fourth side 64 and the fifth side 65.

As can be understood from FIGS. 7 and 8, the cable holder 1 of the embodiment includes ribs 52 on the inner surface of the hollow portion 51 provided on the side. Thereby, even on the side where the hollow portion 51 is provided, the rigidity can be increased.

In the embodiment, the holder portion 11 has a configuration in which a hollow portion 51 is provided over adjacent sides and a portion is not provided with a hollow portion 51 over adjacent sides. Therefore, the holder portion 11 is configured to have a wide opening while maintaining a certain degree of rigidity.

Although the present invention has been described above using the embodiments as examples, the present invention is not limited to the above embodiments, and can be modified in various ways. For example, in the embodiment, the angle between the fourth side and the fifth side is different from 90 degrees, but the angle between the fifth side and the sixth side, between the third side and the fourth side, etc. is different from 90 degrees. You can also put it at an angle. Of course, the angles of the illustrated portions are not the only ones that can be changed, and other patterns are also possible. No matter how the angle is formed, it is sufficient to form it so that a biasing force is applied in a direction perpendicular to the direction of attachment and detachment of the lock.
