  Next, the optical cable K2 drawn into the box body 20 is connected to the mechanical splice 58, and the optical cable K1 connected to the mechanical splice 58 is connected to the optical adapter 13 of the optical connecting device 11. Next, the tray 50 is attached to the box body 20. Among the pair of box side mounting portions 23a, 24a, the tray 50 is inserted so that the tray side mounting portion 51 is inserted into the box side mounting portions 23a, 24a farthest from the lower short side wall 25 (upward). Is moved along the opening surface H, in other words, along the inner surfaces of the long side walls 23 and 24 of the box body 20. That is, the lower long side surface 50 c of the tray 50 is moved along the direction in which the tray 50 is separated from the lower short side wall 25. Thereafter, the tray 50 is moved from the opening surface H of the box body 20 into the box body 20. Then, the tray-side attachment portion 51 is guided toward the box-side attachment portions 23a and 24a by the guide grooves 23b and 24b, and is inserted into the box-side attachment portions 23a and 24a as they are to attach the tray 50 to the box body 20.

  The tray 50 is attached to the box body 20 by locking the locking projections 52a in the locking holes 23c, 24c closest to the upper short side wall 26 of the pair of locking holes 23c, 24c. Then, a space for allowing the optical adapter 13 to escape is formed between the lower long side surface 50 c of the tray 50 and the inner surface of the lower short side wall 25, and the optical adapter 13 is obstructed in mounting the tray 50 to the box body 20. The tray 50 is attached to the box body 20 without becoming. The tray 50 is attached to the box body 20 with a gap between the upper long side surface 50d and the inner surface of the upper short side wall 26.

  Next, the optical cable K1 connected to the optical adapter 13 is drawn to the front side of the tray 50 from between the long side surface 50d on the upper side of the tray 50 and the inner surface of the upper short side wall 26, and the optical cable is drawn from the inlet 60 on the upper side of the tray 50. K1 is pulled into the cable housing portion 55, and the retaining piece 61 prevents the optical cable K1 from being pulled out forward from the service port 60. Then, a portion that becomes the extra length of the optical cable K1 is wound around the winding portion 54. Further, the optical cable K2 connected to the mechanical splice 58 is wound around the winding portion 54 and pulled out of the tray 50 from the drawing port 60 below the tray 50. At this time, the retaining piece 61 prevents the optical cable K2 from being pulled forward from the inlet 60. Further, the mechanical splice 58 is held by the splice holder 57.

  Here, when it is necessary to adjust the fixing position of the optical connection device 11 with respect to the bottom wall 21 (for example, the lower surface of the optical connection device 11 is separated from the inner surface of the lower short side wall 25), first, the elastic piece 52 To release the locking of the locking projection 52a into the locking holes 23c and 24c, and the tray 50 is rotated around the tray side mounting portion 51 as the rotation center to open the accommodation space S. Then, the optical cables K1 and K2 are extracted from the drawing port 60 and unwound from the winding portion 54. And after changing the fixing position of the optical connection apparatus 11, while rotating the tray 50 and attaching it to the box main body 20, optical cable K1, K2 is wound around the winding part 54. FIG.

  Next, the optical cable K2 is clamped by the bush 40, and the bush 40 is attached to the attachment recess 33 by press-fitting the press-fit protrusion 42 and the hinge 43 into the press-fit recess 33a. Then, the optical cable K2 is held by the box body 20 so as to extend toward the tray 50 by the bush 40.

  When the optical cable K2 is held by the bush 40 and the optical cable K1 is drawn from the box body 20 into the cable housing 55, the optical cables K1 and K2 are connected to the inside of the tray 50 from the upper and lower long side surfaces 50c and 50d. Has been drawn into. The optical cables K1 and K2 are drawn into the tray 50 so as to extend along the left and right short side surfaces 50a and 50b of the tray 50.

  Then, the lid body 70 is rotated so as to close the housing space S of the box body 20 by the lid body 70, and the latching piece is latched on the latching projection piece 29 a of the box body 20. Restrict movement. As a result, the optical connection device 11 is accommodated in the device accommodation box 10 and the optical cables K1 and K2 are connected to the optical connection device 11. A coaxial cable (not shown) is connected to the output terminal 16.

  Here, unlike the optical connection device 11, an optical connection device (not shown) in which the optical adapter 13 is fixed to the side surface (for example, the right side surface) of the case 12 is fixed to the bottom wall 21, and the device storage box 10 is fixed. The case of assembling will be described. In this case, when the tray 50 is attached to the box body 20, the tray side attachment portion 51 is attached to the box side attachment portions 23 a and 24 a closest to the lower short side wall 25 among the pair of box side attachment portions 23 a and 24 a. And the tray 50 is attached to the box body 20.

  The tray 50 is attached to the box body 20 by locking the locking protrusions 52a in the locking holes 23c, 24c farthest from the upper short side wall 26 out of the pair of locking holes 23c, 24c. Then, the lower long side surface 50c of the tray 50 and the inner surface of the lower short side wall 25 come into contact with each other, and the tray 50 is attached to the box body 20 without forming a space between both surfaces. That is, since the optical adapter 13 is fixed to the side surface of the case 12, the tray 50 is attached to the box body 20 without the optical adapter 13 becoming an obstacle to the attachment of the tray 50 to the box body 20.

  In this case as well, the tray 50 is attached to the box body 20 with a gap between the tray 50 and the inner surface of the upper short side wall 26. For this reason, the optical cable K1 extending from the cable housing portion 55 toward the optical connection device 11 extends toward the optical connection device 11 through the space between the tray 50 and the inner surface of the short side wall 26 while being gently bent.

According to the above embodiment, the following effects can be obtained.
(1) The tray-side attachment portions 51 are formed on the pair of short side surfaces 50 a and 50 b facing the back of the tray 50, and the pair of box-side attachment portions 23 a and 24 a are formed on the long side walls 23 and 24 of the box body 20. Then, by selecting the box side mounting portions 23a and 24a into which the tray side mounting portion 51 is inserted, a space is formed between the inner surface of the short side wall 25 on the lower side of the box body 20 and the long side surface 50c on the lower side of the tray 50. It can be selected whether or not to form. That is, the attachment position of the tray 50 to the box body 20 can be changed along the direction in which the opening surface H extends. Therefore, when the optical adapter 13 is fixed to the front surface of the optical connection device 11, a space for allowing the optical adapter 13 to escape is formed between the inner surface of the short side wall 25 and the long side surface 50c below the tray 50. The tray 50 can be attached to the box body 20 without the optical adapter 13 becoming an obstacle. Therefore, according to the device storage box 10, it is possible to cope with the installation of two types of optical connection devices 11 having different fixing positions of the optical adapter 13 without increasing the size of the box main body 20, and as a result, the box main body 20. It is no longer necessary to secure a large installation space.

  (2) Each pair of box-side attachment portions 23a, 24a is arranged in parallel along the direction in which the optical cables K1, K2 are drawn into the box body 20. For this reason, as a result of adjusting the mounting position of the tray 50 in order to avoid interference between the optical adapter 13 and the tray 50, the pulling direction of the optical cables K1, K2 into the tray 50 is changed, and the mounting position of the tray 50 is adjusted. Therefore, the optical cables K1 and K2 can be prevented from being bent or damaged.

  (3) Two inlets 60 are formed in each of the upper and lower long side surfaces 50c, 50d of the tray 50. Therefore, the positions where the optical cables K1, K2 are drawn into the tray 50 can be selected according to the wiring positions of the optical cables K1, K2. Therefore, when the optical cables K1 and K2 are drawn into the tray 50, the optical cables K1 and K2 are not forcibly bent, and the optical cables K1 and K2 can be prevented from being damaged.

  (4) A large number of fixing holes 21a are formed in the bottom wall 21, and each fixing hole 21a is formed in a long hole shape. For this reason, even if the fixing position of the optical connecting device 11 with respect to the bottom wall 21 is changed, the fixing screw 15 inserted through the fixing piece 14 of the optical connecting device 11 can be screwed into the fixing hole 21a.
