By the way, when stacking and using the wiring housing units as described in Patent Document 1, it is conceivable to draw the optical cable 102 into each wiring housing unit 101 as shown in FIG. In this case, since it is necessary to route the relatively large-diameter optical cable 102 to a plurality of places, the wiring work may be complicated. Further, as shown in FIG. 12, it is also conceivable that the optical cable 102 is drawn into one wiring housing unit 101, and the optical fiber 103 not covered by the optical cable 102 is inserted into another wiring housing unit 101. However, with such a configuration, a part of the optical fiber 103 is located outside the wiring housing unit 101. Since the optical fiber 103 is relatively weak against a load from the outside, it is not preferable to position the optical fiber 103 outside the wiring housing unit 101.

The inventor of the present case tried to solve the problem by diligently examining this point. An object of the present invention is to enable wiring to each wiring storage unit in a wiring storage structure formed by stacking wiring storage units by routing the wiring within the wiring storage structure.

In order to solve the above problems, the following means are adopted. A first means is a wiring storage structure in which wiring storage units for storing wiring are stacked, and a first wiring storage unit including a clamp portion for fixing wiring drawn from the outside, and the first wiring A second wiring storage unit having a wiring port forming portion which is arranged on the upper side of the storage unit and has a wiring port introduction portion capable of introducing wiring into a bottom plate at a position corresponding to the clamp portion.

In the first means, the second means is preferably configured such that the lid portion that covers the wiring port forming portion is detachable.

In the second means, the third means is preferable in which the lid portion is provided with the clamp portion.

In the second or third means, a fourth means is preferable, in which the lid portion can be fixed to a reinforcing portion formed on the bottom plate of the first wiring housing unit.

According to the present invention, the wiring that is inserted into the wiring storage unit located above the stacked wiring storage units can be introduced from the bottom plate side of the wiring storage unit, so that wiring can be performed without exposing the optical fiber to the outside of the housing. It becomes possible to do.

Modes for carrying out the invention are shown below. FIG. 1 is a perspective view of a wiring storage structure 1 according to the first embodiment. FIG. 2 is a view on arrow II-II of FIG. FIG. 3 is a side view of the wiring housing structure 1 according to the first embodiment. The wiring storage structure 1 of the present embodiment is configured by stacking wiring storage units 3 that store wiring. In addition, the wiring housing unit 3 is in a state in which the back surface is opened so that wiring from the outside can be drawn.

The wiring storage structure 1 of the present embodiment includes a first wiring storage unit 3a having a clamp portion 5 for fixing the wiring drawn from the outside. Further, the second wiring storage unit 3b is provided on the upper side of the first wiring storage unit 3a and has the wiring port forming portion 7 capable of introducing the wiring into the bottom plate 22 at the corresponding position of the clamp portion 5. With such a configuration, it is possible to introduce the wiring to be inserted into the second wiring storage unit 3b located above the stacked wiring storage units 3 from the bottom plate 22 side of the second wiring storage unit 3b. Therefore, the optical fiber 26 can be wired without taking it out of the housing 32. The wiring port forming portion 7 in the present embodiment is a wiring port formed in a rectangular shape.

In this embodiment, the optical cable 25 obtained by bundling and covering the optical fibers 26 is fixed by the clamp portion 5. The optical cable 25 is uncovered around the clamp portion 5, a part of the optical fiber 26 is wired in the first wiring housing unit 3a, and a part of the optical fiber 26 is in the second wiring housing unit 3b. Will be introduced in. In the present embodiment, the optical fiber 26 extending from the first wiring storage unit 3a passes through the wiring port forming portion 7 provided in the bottom of the second wiring storage unit 3b in an opening shape, and then the second wiring is formed. It is introduced into the storage unit 3b.

The uncovered optical fiber 26 of the optical cable 25 can be connected to an optical fiber 28 extending from the patch panel 33. The optical fiber 26, which is connected to the optical fiber 28 by fusion, is stored in the fusion tray 34 with the extra length portion including the connection portion wound in a loop.

Here, the wiring storage unit 3 of the first embodiment will be described. The first wiring storage unit 3a and the second wiring storage unit 3b have substantially the same form and are provided with a casing 32 having an outer shape that is substantially C-shaped. The housing 32 is provided with a mounting portion 36 that can be mounted on a mount angle of a rack (not shown). As shown in FIGS. 4 and 5, an L-shaped plate in plan view is used for the mounting portion 36 of the present embodiment, and is provided on both sides of the housing 32. The mounting portions 36 provided on the housing 32 are arranged such that their ends project from each other with respect to the housing 32.

The bottom plate 22 of the housing 32 has an opening serving as the wiring port forming portion 7. Further, a reinforcing portion 37 that suppresses deformation of the bottom plate 22 of the housing 32 is fixed. The reinforcing portion 37 is fixed in the lateral direction of the housing 32.

The wiring housing unit 3 of the present embodiment is provided with a patch panel 33 to which a connector can be connected. In the patch panel 33 of the present embodiment, the connector can be connected from the front side of the wiring housing unit 3. The patch panel 33 is connected to the housing 32 by a hinge 42, and the patch panel 33 is rotatable.

The patch panel 33 according to the present embodiment is configured to be located rearward of the mounting position of the mount angle. For this reason, even in the case of a rack whose front surface is open, such as an open rack, it is possible to avoid the state where the wiring is exposed to the front side.

A front guide portion 44 located on the front side of the patch panel 33 and a rear guide portion 45 located on the rear side are formed so as to be integrated with the patch panel 33. Therefore, when the patch panel 33 moves, the front guide portion 44 and the rear guide portion 45 also move. Therefore, the structure is such that the work of connecting the connector inside the wiring housing unit 3 can be performed relatively easily. As shown in FIGS. 6 and 7, a plurality of cable guides 47 are attached to the rear guide portion 45, and the optical fiber 28 can be entangled in the cable guides 47.

The rear guide portion 45 is always guided by the bottom plate 22 when the patch panel 33 is rotated. Therefore, it is possible to prevent the end portion of the patch panel 33 from being lowered due to the weight of the connector and the wiring, and prevent the hinge 42 from being excessively loaded.

The end portion of the front guide portion 44 is formed in a notch shape. Therefore, as shown in FIG. 8, even if the patch panel 33 is rotated, a space 49 continuing downward is secured in front of the front panel 86. Therefore, even when the patch panel 33 is opened, the load on the wiring is suppressed.

The main difference between the first wiring storage unit 3a and the second wiring storage unit 3b is whether or not the lid 62 is attached. When the wiring port forming portion 7 is not covered with the lid portion 62, the optical fiber 26 and the like can be drawn through the bottom plate 22 as the second wiring housing unit 3b. Further, when the wiring port forming portion 7 is covered with the lid portion 62, it can be used as the first wiring housing unit 3a. The lid portion 62 is provided with the clamp portion 5. However, in the wiring storage structure 1 of the present embodiment, the wiring port forming portion 7 of the second wiring storage unit 3b is directly above the clamp portion 5. Will be located. The lid portion 62 of the present embodiment is formed to have a crank shape by bending the end portion at a right angle. Further, the lid portion 62 is configured so that it can be attached to any of the stacked wiring storage units 3.

In the present embodiment, since the lid portion 62 that covers the wiring port forming portion 7 is configured to be removable, it is possible to easily switch between a state where the wiring port is opened and a state where the wiring port is closed. Therefore, it is possible to select each time whether the prepared wiring storage unit 3 is used as the first wiring storage unit 3a or the second wiring storage unit 3b. Further, since the detachable lid portion 62 is provided with the clamp portion 5, if a plurality of wiring storage units 3 of the same type are prepared, the wiring opening forming portion 7 is provided at a position corresponding to the clamp portion 5. It becomes possible easily. A space 62a is provided between the end of the clamp part 5 and a fixed side 66a for fixing the reinforcing part 37, which will be described later, and the space is fixed, so that the bending radius of the optical fiber 26 can be secured.

In the present embodiment, the lid portion 62 that covers the wiring port forming portion 7 is fixed so as to be connected to the reinforcing portion 37, and the lid portion 62 also plays a role of reinforcing the wiring housing unit 3. As shown in FIG. 9, the lid portion 62 of the present embodiment is provided with fixed sides 66a and 66b in which the reinforcing portion attachment portion 64 and the bottom plate attachment portion 65 are formed, and the lid portion 62 is attached to the housing 32. It is possible to fix with screws. More specifically, in the first wiring housing unit 3a of the present embodiment, the fixed side 66a at one end of the lid portion 62 is screwed to the reinforcing portion 37, and the other end of the lid portion 62 is provided. The fixed side 66b is screwed to the rising side 38 raised from the end of the bottom plate 22 of the housing 32. The lid portion 62 fixed to the reinforcing portion 37 formed to prevent the deformation of the bottom plate 22 of the wiring housing unit 3 plays a role of covering the opening formed as the wiring port forming portion 7, and The one fixed side 66 has a structure in which it is screwed to the wiring housing unit from different angles, and also plays a role of reinforcing the wiring housing unit 3 in different directions. In addition, a reinforcing side 67 for reinforcing the lid portion 62 is formed on a side different from the side on which the fixed side 66 is formed, and a cutout hole 68 is formed between the fixed side 66b and the reinforcing side 67 to position on the rising side 38. Is possible.

Further, by covering the fusion tray 34 with the cover portion 84, it is possible to suppress the floating of the optical fiber 26 in the fusion tray 34. In the present embodiment, the cover portion 84 is fixed to the housing 32 by screwing the one end of the cover portion 84 into the reinforcing portion 37 and fixing it to the rising side 38. A ceiling plate fixing rail 88 used when fixing a ceiling plate (not shown) can be attached to the upper portion of the housing 32 of the present embodiment. Although the reinforcing portion 37 of the lid portion 62, the fixing to the rising edge 37, and the fixing of the cover portion 84 to the rising edge 38 are fixed by screws, a fixing member such as a nail latch that does not require a tool is used. May be

Next, a second embodiment will be described. FIG. 10 is an exploded perspective view of the wiring storage unit 3 according to the second embodiment. The wiring port forming portion 7 of the present embodiment employs a knockout opening in which a portion which is an edge of the wiring port is partially cut out. Since the knockout opening is adopted in the present embodiment, the wiring port forming portion 7 can be closed in the initial state. Further, if necessary, a load can be applied to the inside of the cutout portion to form an opening-shaped wiring port.

Further, the lid portion 62 of the present embodiment is provided with an opening portion 82 through which the optical fiber 26 and the like can pass. Therefore, even when the wiring port forming portion 7 is covered with the lid portion 62, the optical fiber 26 and the like can be wired below the lid portion 62. For this reason, it becomes possible to route the wiring within the wiring housing structure 1 and to route the optical fiber 26 in the wiring housing unit 3 arranged below the wiring housing unit 3 including the clamp portion 5. The opening 82 is formed in the space 62a between the end of the clamp 5 and the fixed side 66a.

Although the two embodiments have been described above, the present invention is not limited to the above-described embodiments, and various modes are possible. For example, the unwound optical fiber of the optical cable may be configured by integrating several (for example, four) fibers.

It is also possible to provide a protective member around the optical fiber at a portion where the optical cable is not coated. Such a protection member can be formed in a tube shape, for example.

It is also possible to form a knockout opening in the lid and form an opening portion when necessary.
