  SUMMARY OF THE INVENTION An object of the present invention is to solve the above-described conventional problems and provide an adapter mounting member that is provided with a plurality of types of mounting holes for mounting a plurality of types of adapters having different shapes and that is reduced in size.

  The present invention made to solve the above-mentioned problems is an adapter mounting member in which a mounting hole that enables mounting of a repetitive shaped adapter for connecting a connector of an optical fiber cord to the mounting panel is formed, The mounting hole includes a first mounting hole in which the first adapter can be mounted, and a second mounting hole in which a second adapter having a shape different from the first adapter can be mounted. The second mounting hole is overlapped.

  According to a second aspect of the present invention, in the adapter mounting member according to the first aspect, the first mounting hole and the second mounting hole are formed so as to be shifted in the height direction and the width direction, respectively. It is.

  According to a third aspect of the present invention, in the adapter mounting member according to the second aspect, the upper and lower ends of the mounting panel provided perpendicular to the device mounting surface are bent in a direction parallel to the device mounting surface. The formed bent sides are projected in opposite directions to form a substantially crank shape, and the bent sides are fixed sides for fixing to the device mounting surface.

  According to a fourth aspect of the present invention, in the adapter mounting member according to the third aspect, the adapter has an adapter holder that is locked to the mounting hole, and the bent side is mounted at the mounting position of the adapter in the mounting hole. Is formed at a height position overlapping with the adapter holder or the adapter.

  The adapter mounting member according to the present invention is formed by forming a mounting hole in which a repetitive-shaped adapter can be mounted on the mounting panel. The mounting hole includes a first mounting hole in which the first adapter can be mounted and The second adapter is provided with a second mounting hole that allows a second adapter having a shape different from that of the first adapter to be mounted, and the first mounting hole and the second mounting hole are overlapped. Thereby, the height of the adapter attachment member in the height direction and the width direction can be reduced, the adapter attachment member can be reduced in size, and the internal space of the optical junction box is not compressed.

  According to a second aspect of the present invention, in the adapter mounting member according to the first aspect, the first mounting hole and the second mounting hole are formed so as to be shifted in the height direction and the width direction, respectively. For example, when the first mounting hole and the second mounting hole having the same width are arranged by shifting only in the height direction, when the adapter is mounted, the movement of the adapter in the vertical direction cannot be restricted. According to the configuration of the second aspect, when each adapter is attached, a restricting portion for holding the adapter is formed, and the movement of the adapter in the vertical direction can be restricted.

  According to a third aspect of the present invention, in the adapter mounting member according to the second aspect, from the upper and lower ends of the mounting panel provided perpendicular to the device mounting surface, the bent side is formed in a direction parallel to the device mounting surface. They are formed and protruded in opposite directions to form a substantially crank shape, and the bent side is used as a fixed side for fixing to the device mounting surface. Thereby, when it changes to the adapter from which a shape differs, the height position of an adapter can be changed by inverting and using an adapter attachment member up and down.

Preferred embodiments of the present invention are shown below.
As shown in FIGS. 1 to 3, the inside of the optical junction box 1 is divided into three stages by a first wiring partition plate 2 and a second wiring partition plate 3. Parts that are unlikely to be operated by a person are arranged on the first stage close to the bottom surface, and parts that are relatively likely to be operated by a person are arranged on the second and third stages. In the first stage, an optical fiber connecting portion for entering an optical fiber cord (not shown) and an extra length tray 4 for accommodating an extra length portion of the optical fiber cord are arranged. Further, an adapter mounting member 5 for mounting and holding an adapter to which an optical fiber cord connector is connected is provided adjacent to the extra length tray 4. A first wiring partition plate 2 is pivotably mounted above the extra tray 4 and a media converter 6 is mounted at a position corresponding to the second stage. Further upward, the second wiring partition plate 3 is pivotally attached to the optical junction box main body, and a hub, router, etc. connected to the communication equipment as shown in FIG. The electronic electrical device 7 is mounted.

  As shown in FIG. 4, the adapter mounting member 5 of the present embodiment has a repetitive shape for connecting a connector of an optical fiber cord to a mounting panel 8 formed perpendicular to the bottom surface which is a device mounting surface. A mounting hole is formed so that the adapter can be attached. The mounting holes are a first mounting hole 11 in which the first adapter 9 can be mounted as shown in FIG. 6 and a second adapter 10 in which the second adapter 10 having a shape different from that of the first adapter 9 can be mounted in FIG. The mounting hole 12 is included. Further, as shown in FIG. 5, an overlapping space 13 in which the first mounting hole 11 and the second mounting hole 12 overlap is formed. Thereby, the length of the adapter attachment member 5 in the height direction and the width direction can be reduced by an amount corresponding to the overlap space 13, and more specifically, the first attachment hole 11 and the second attachment hole 12 are formed in one stage. Thus, the width direction can be reduced, the height direction can be reduced as compared with the case where the first mounting hole 11 and the second mounting hole 12 are formed in two stages, and the adapter mounting member 5 can be reduced in size. Thus, the inner space of the optical junction box 1 is not compressed.

  The first mounting hole 11 and the second mounting hole 12 are formed so as to be shifted in the height direction and the width direction as shown in FIG. Accordingly, when the first adapter 9 is attached to the first attachment hole 11 as shown in FIG. 6, the restricting portion 14 comes into contact with the lower end portion of the first adapter 9, thereby moving the first adapter 9 in the vertical direction. Can be regulated. Similarly, even when the second adapter 9 is attached, the movement of the second adapter 9 in the vertical direction can be restricted by the restricting portion 14.

  As shown in FIG. 4, from the upper and lower ends of the mounting panel 8, bent sides 15 that are bent in a direction parallel to the bottom surface are projected so as to be substantially crank-shaped in opposite directions. It was. Further, the bent side 15 is a fixed side fixed to the device mounting surface, and the adapter mounting member 5 is fixed to the optical junction box body using the fixing hole 16 formed in the bent side 15 serving as the fixed side. . Thus, for example, when the first adapter used as shown in FIGS. 6 to 8 is changed to the second adapter, the adapter mounting member 5 is turned upside down, and the second adapter 10 is changed as shown in FIG. Can be attached to the second attachment hole 12 for use. Further, since the adapter mounting member 5 can be used upside down as described above, the height positions of the first adapter 9 and the second adapter 10 can be arbitrarily changed according to the use situation. Although the bent side 15 may be U-shaped, in that case, there is a problem that when the screw is fixed, the upper bent side 15 gets in the way and the tool does not enter, resulting in poor workability. It is possible to improve the workability of tool insertion by forming it in a crank shape.

  As shown in FIGS. 8 and 11, the first adapter 9 and the second adapter 10 each have an adapter holder 17 that is attached to the first attachment hole 11 or the second attachment hole 12 of the adapter attachment member 5. The adapter holder 17 includes a locking piece 17b made of an elastic piece locked to the opening periphery of the mounting hole, and a wide portion 17a formed wider in the vertical and horizontal directions than the mounting hole in order to prevent dropping from the mounting hole. Have.

  Here, as shown in FIGS. 7 and 10, the bent side 15 of the adapter mounting member 5 is formed at the upper or lower position of the first mounting hole 11 and the second mounting hole 12, and further, the first adapter 9 or At the position where the second adapter 10 is attached to the first attachment hole 11 or the second attachment hole 12, the bent side 15 is formed at a height position overlapping the wide portion 17 a of the adapter holder 17. That is, the first adapter 9 and the second adapter 10 can be inserted only from the opposite side on which the bent side 15 is formed. When the first adapter 9 and the second adapter 10 are inserted from the side of the bent side 15, the wide portion 17 a contacts the bent side 15 and cannot be inserted. It is like that. For this reason, the mistake of the attachment direction of the 1st adapter 9 and the 2nd adapter 10 can be prevented. Furthermore, since the bent side 15 of the present embodiment is formed in a crank shape, the first adapter 9 and the second adapter 10 can be restricted from being inserted from different surfaces.

  The first adapter 9 shown in FIGS. 7 and 8 is one in which attachment pieces 9a having screw holes are formed at the upper and lower ends of the optical fiber connecting portion 9b of the optical fiber cord. In this case, at the position where the first adapter 9 is attached to the first attachment hole 11, the optical fiber connection portion 9 b is inserted into the first attachment hole 11, and the attachment piece 9 a is formed on the upper and lower outer sides than the first attachment hole 11. The attachment piece 9a is formed at a position overlapping the bent side 15. Moreover, when it is going to insert the 1st adapter 9 from the bending side 15 side, not the adapter holder 17 but the 1st adapter 9 may contact | abut to the bending side 15, and it may prevent insertion.

  In the present embodiment, the adapter holder 17 is used for locking and holding the first adapter 9 and the second adapter 10 in the first mounting hole 11 and the second mounting hole 12, respectively. For example, the adapter holder 17 may not be provided, and the adapter may be attached to the attachment hole by screwing.

  In the present embodiment, as shown in FIGS. 1 to 3, the first optical fiber cord connector is easily connected to the media converter 6 arranged in the second stage or connected to the optical fiber cord connector from the media converter 6. The adapter mounting member 5 is arranged so that the mounting hole 11 is at the top, and the first adapter 9 is mounted at a position parallel to the media converter 6. Thereby, the internal space of the optical junction box 1 can also be used effectively by using the lower space formed in the lower position of the 1st adapter 9 as FIG. 12 as a wiring storage space or a partition.
