DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] The following describes an embodiment of the invention. As can be understood from FIGS. 1 to 4, the optical connection box 1 of this embodiment includes a main body 10 having an opening on the front side, and a cover 20 capable of covering the opening on the front side of the main body 10. The optical connection box 1 includes an insertion port 11 through which an optical wiring can be introduced into the inside of the main body 10 on at least a part of the surface of the main body 10, and the cover 20 includes a cover-side covering part 21 capable of covering at least a part of the insertion port 11 in an openable and closable manner, and the main body 10 includes a main body-side covering part 12 capable of covering at least a part of the insertion port 11 in an openable and closable manner. This makes it possible to provide an optical connection box 1 including an optical wiring insertion port 11 whose open and closed state can be freely changed. Note that the cover-side covering part 21 and the main body-side covering part 12 do not necessarily rotate to open and close the insertion port 11, but may open and close the insertion port 11 by sliding, attaching and detaching, or the like.

[0016] Here, the optical junction box 1 of the embodiment will be described. The outline of the outer shape of the optical junction box 1 of the embodiment is formed by a bottomed cylindrical main body 10 with an open front side, and a cover 20 capable of covering an opening provided on the front side of the main body 10. The optical wiring is routed inside the main body 10, and an adapter module 50 equipped with an optical adapter 51 connected to the optical wiring is attached inside the main body 10 (see FIG. 5). The cover 20 of the embodiment is detachable from the main body 10. The cover 20 also has a shaft stopper 22, and is attached to the main body 10 so as to be rotatable.

[0017] The optical connection box 1 of the embodiment is connected to an optical cable 95 extending from a utility pole (see FIG. 6). The adapter module 50 of the embodiment is provided with optical wiring that is connected to the optical fiber of the optical cable 95 introduced from the outside. In the adapter module 50, optical fibers, optical cords, etc. are arranged as optical wiring. The optical adapter 51 provided in the adapter module 50 is capable of mounting a plurality of connectors. The optical adapter 51 can connect an internal connector 81 provided at the end of the optical wiring wound around the adapter module 50 to an external connector 91 extending from a communication device side such as a media converter in a house so as to be continuous (see FIG. 7). When the cover 20 is closed from the state shown in FIG. 7, the state shown in FIG. 8 is obtained.

[0018] In the optical connection box 1 of the embodiment, the axis about which the cover 20 rotates is configured to extend in the vertical direction. The insertion opening 11 is formed at a position above and below the rotation axis. The main body 10 is provided with a main body-side covering part 12 capable of covering at least a part of the insertion opening 11, and in the example shown in Figs. 1 to 3, the main body-side covering parts 12 are provided on both the upper end side and the lower end side of the main body 10.

[0019] It is not necessary that the body-side covering part 12 is provided on both the upper end side and the lower end side of the body 10. For example, the body-side covering part 12 may be provided on only one of the upper end side and the lower end side of the body 10.

[0020] When there are a plurality of body-side covering parts 12, the body-side covering parts 12 may be used in a mixture of those that cover at least a part of the insertion opening 11 and those that do not. For example, the body-side covering parts 12 located on the upper side of the body 10 may be used so as to cover at least a part of the insertion opening 11 and the body-side covering parts 12 located on the lower side of the body 10 may be used so as not to cover the insertion opening 11, or vice versa.

[0021] The cover 20 is also provided with a cover-side covering portion 21 capable of covering at least a portion of the insertion opening 11. In the example shown in Fig. 1 to Fig. 4, the cover 20 is provided with two cover-side covering portions 21 on each of the upper end side and the lower end side.

[0022] It is not necessary that the cover side covering portion 21 is provided on both the upper end side and the lower end side of the cover 20. For example, the cover side covering portion 21 may be provided on only one of the upper end side and the lower end side of the cover 20.

[0023] Furthermore, the number of cover-side covering parts 21 is arbitrary. When there are a plurality of cover-side covering parts 21, some of the cover-side covering parts 21 cover at least a part of the insertion opening 11 and some do not. For example, when at least some of the cover-side covering parts 21 are arranged in the left-right direction, one of the left and right cover-side covering parts 21 may be used so as to cover at least a part of the insertion opening 11 and the other cover-side covering part 21 does not cover the insertion opening 11.

[0024] In order to broaden the range of options for the insertion opening 11, it is preferable to provide the insertion openings 11 on multiple surfaces of the main body 10, provide multiple cover-side covering parts 21 on the cover 20, and provide multiple main body-side covering parts 12 on the main body 10, but it is not necessary to be limited to such an example. Note that the main body 10 in the embodiment has a substantially rectangular cross section cut along a plane perpendicular to the front-rear direction, and is provided with the insertion openings 11 on the top and bottom surfaces, but it may also be configured to provide the insertion openings 11 on other surfaces such as the right surface, left surface, and rear surface.

[0025] Incidentally, when the cover 20 is rotatable with respect to the main body 10, it is preferable to provide the main body side covering part 12 on the rotation center side of the cover 20 rather than the part of the insertion opening 11 that can be covered by the cover side covering part 21. The part of the cover 20 on the rotation center side is likely to come into contact with the main body 10, and may be an obstacle to the closing operation. However, if the main body side covering part 12 is provided at a position closer to the rotation center and the cover 20 is closed with the main body side covering part 12 open, the cover 20 can be closed smoothly. If there is a main body side covering part 12 that needs to be closed during use, the necessary part of the main body side covering part 12 can be closed after the cover 20 is closed.

[0026] Incidentally, the cover side covering part 21 in the embodiment has a tapered shape at the tip side. In this way, even when the cover side covering part 21 is in a closed state, it is possible to prevent the cover side covering part 21 from interfering with the operation of closing the cover 20. Also, when working to open the cover side covering part 21, the cover side covering part 21 can be operated from various angles.

[0027] In the embodiment, the insertion opening 11 partially covered by the cover-side covering part 21 extends to a position rearward of the area reachable by the cover-side covering part 21, so that the optical wiring can be inserted even when the insertion opening 11 is partially covered by the cover-side covering part 21. Therefore, the optical wiring can be inserted into the insertion opening 11 even when the cover-side covering part 21 is closed.

[0028] 3 to 5, in the embodiment, the insertion opening 11 is widened so that a plurality of groove-shaped rear insertion portions 11a are formed at a position rearward of the area where the cover-side covering portion 21 can reach, and the insertion opening 11 can be used to distinguish between the optical wiring passing through this portion and the optical wiring passing through the front portion. The rear insertion portion 11a may be provided separately from the insertion opening 11, and for example, a separate through hole may be provided rearward of the insertion opening 11. If such a rear insertion portion 11a is provided, it is also possible to use the insertion opening 11 such that the external connector 91 is passed through, and an optical cord or the like is passed through the rear insertion portion 11a located rearward of the insertion opening 11 (see FIG. 9).

[0029] Incidentally, as can be seen from Fig. 10, the optical junction boxes 1 of the embodiment can also be stacked so as to overlap in the front-rear direction. Considering such a method of use, it is preferable that an openable opening 23 is provided in a part of the cover 20, and the rear surface of the main body 10 is configured to have a rear opening 13 at a position facing the opening 23 when the optical junction boxes 1 are stacked so as to overlap in the front-rear direction (see Figs. 11 and 12). This makes it easier to route optical wiring between the optical junction boxes 1 located at the front side and the optical junction boxes 1 located at the rear side.

[0030] 10, it is preferable that at least one of the cover-side covering part 21 or the body-side covering part 12 is configured to be capable of separating a space near a part of the insertion opening 11 of the optical connection box 1 located on the front side from a space near a part of the insertion opening 11 of the optical connection box 1 located on the rear side when the optical connection boxes 1 are stacked so as to overlap in the front-to-rear direction. This is because it is easy to organize the optical wiring.

[0031] It is preferable that the box body of the optical junction box 1 is configured to be symmetrical up and down. In this way, it can be turned upside down when attaching the adapter module 50. Therefore, for example, by turning the adapter module 50 upside down while keeping the main body 10 fixed at the installation location, the outgoing direction of the optical wiring can be reversed upside down.

[0032] In the embodiment, the protrusion 41 and the engagement hole 42 are designed to be able to engage with each other so that the cover side covering part 21 can be easily maintained in a closed state when the cover side covering part 21 is closed. In the example shown in Fig. 13 and Fig. 14, the cover side covering part 21 is provided with the protrusion 41, and the side wall of the main body part 10 is provided with the engagement hole 42.

[0033] In the embodiment, the groove 45 and the engagement piece 46 are designed to engage with each other so that the body-side covering part 12 can easily maintain the closed state when it is closed. In the example shown in Fig. 15, the body-side covering part 12 is provided with the engagement piece 46, and the side wall of the body part 10 is provided with the groove 45. Note that in the embodiment, in consideration of the possibility of introducing the optical cable 95 from near the body-side covering part 12, a protrusion 48 that can be used when fixing the optical cable 95 with a cable tie is provided near the body-side covering part 12 (see Fig. 5).

[0034] In the optical connection box 1 of the embodiment, the adapter module 50 is rotatably attached to the main body 10, and as can be seen from FIG. 16, the optical wiring can be wound around the main body 10, but this is not necessarily the case.

[0035] Although the present invention has been described above by taking the embodiment as an example, the present invention is not limited to the above embodiment and can be embodied in various forms. [Explanation of symbols]
