Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
<Example 1> FIG.1 and FIG.2 shows one Example of the optical connector arrangement | sequence case provided with the attachment member based on this invention. The optical connector array case having the mounting member includes an optical connector array case 25 in which a plurality of optical connectors are arrayed on the lower end surface of the case body, a case holder 37 that detachably holds the optical connector array case 25, and a cabinet or an architecture. It is comprised from the fixed plate 39 fixed to the wall surface (attachment surface) 41, such as a thing, by screwing etc. As shown in FIG.

  The optical connector array case 25 is similar to the optical connector array case 25 of FIG. 16 in that the input body side optical connector 5, the input side optical fiber core wire 7, the optical splitter 9, the output side optical fiber core wire 11, The optical connector 13 and the connector adapters 19 and 21 are incorporated. The case body 23 has a flat shape in which the side surface thickness dimension is smaller than the front width dimension and the height dimension.

  As shown in FIGS. 3 and 4, the optical connector array case 25 of this embodiment has a lower end surface of the case main body 23 in which the connector adapter 21 mounted on the tip of the standby optical connector 13 is viewed from the side. The connector adapters 21 are arranged in a row on a plurality of lower end surfaces 23a, 23b that are formed in a step shape and correspond to the step surfaces of the step. The lower end of the connector adapter 21 opens downward from the lower end surfaces 23 a and 23 b of the case body 23, and serves as a connection port for connecting the counterpart optical connector 15 to the standby optical connector 13. Further, the front wall of the case body 23 corresponding to the step surface of the stairs is a connector slide base 43 when the counterpart optical connector 23 is inserted into and removed from the connector adapter 21 arranged on the lower end surface 23b of the second step. The length of the connector slide base 43 (the length from the first stage end face 23a to the second stage end face 23b) is the length of the protrusion of the counterpart optical connector 15 inserted and connected to the connector adapter 21 from the connector adapter 21. It is almost the same.

  With such a configuration, all the connector adapters 21 can be seen from the front, so that the connection work of the counterpart optical connector 15 can be easily performed. Further, when the counterpart optical connector 15 is inserted into the second-stage connector adapter 21, the counterpart optical connector 15 can be inserted by being slid while being pressed against the connector slide base 43. Also, when the counterpart optical connector 15 is pulled out from the second-stage connector adapter 21, it can be pulled out by sliding the counterpart optical connector 15 against the connector slide base 43. That is, it is possible to insert / remove the counterpart optical connector 15 by applying a force to one surface of the counterpart optical connector 15 without picking the counterpart optical connector 15 with fingers. For this reason, even if the space | interval of the connector adapter 21 is narrowed sufficiently, the other party optical connector 15 can be inserted / extracted.

  In addition, when the counterpart optical connector 15 is inserted into and connected to the second-stage connector adapter 21 in front of the connector slide base 43, when the counterpart optical connector 15 is inserted into or removed from the connector adapter 21 on the back side, the near side optical connector 15 is inserted. From both sides of the optical cable 17 (or rubber boot) in the vicinity of the rear end of the optical connector 15 (in short, from both sides of a portion narrower than the optical connector 15), the counterpart optical connector 15 on the back side can be grasped with fingers and inserted. For this reason, since it is not necessary to insert a finger between the counterpart optical connectors 15 (on the connector slide base 43) on the front side, the distance between the connector adapters 21 is made narrower than when the connector adapters are arranged in two rows on the same end face. Thus, the optical connector array case 25 can be downsized.

  The example of FIGS. 3 and 4 is a case where the lower end surface of the case body 23 where the connector adapter 21 of the standby optical connector 11 is arranged is two stages, but the same applies to the case where there are three stages.

  Further, the input side optical connector 5 and the connector adapter 19 are incorporated on one side (right side in FIG. 3A) of the case main body 23 in the standby optical connector arrangement direction. The station side optical connector 3 attached to the tip of the station side optical cable 1 is connected to the input side optical connector 5 via the connector adapter 19. Further, a leg portion 45 extending downward is integrally formed at a portion of the case body 23 where the input side optical connector 5 and the connector adapter 19 are incorporated, and a grip portion 47 is formed at the lower end thereof. The station side optical cable 1 is held and protected by the grip portion 47.

  Next, the fixing plate 39 will be described with reference to FIG. The fixed plate 39 is formed by integrally forming a shaft portion 51 in the lateral direction on the upper part of the front surface (front surface) of a vertically long plate-like portion 49. The shaft portion 51 is integrated with the plate-like portion 49 at both ends. A pair of fixed plate side engaging portions 53 protrude from the lower half of the front surface of the plate-like portion 49. The plate-like portion 49 has a screw hole 55 for screwing the fixing plate 39 to a mounting surface such as a wall.

  Next, the case holder 37 will be described with reference to FIG. The case holder 37 includes a back plate 57 that contacts the back surface of the optical connector array case 25, a side plate 59 that contacts one side surface (on the input side optical connector 5 side) of the optical connector array case 25, and the optical connector. An upper surface plate 61 that abuts on the upper end surface of the array case 25 and an elastic locking piece 63 having a locking claw 63a at the tip that holds the other side surface of the optical connector array case 25 are integrally formed. .

  A first bearing portion 65 is formed on the edge of the upper surface plate 61 on the back surface side so as to be rotatable and detachably engaged with the shaft portion 51 of the fixed plate 39. A second bearing portion 67 is also formed on the edge to engage with the shaft portion 51 of the fixed plate 39 so as to be rotatable and detachable. The first bearing portion 65 has a substantially C-shaped cross section that opens to the back surface side, and the second bearing portion 67 has a substantially C-shaped cross section that opens to one side surface side.

  A pair of holder-side first engaging portions 69 project from the back surface (outer surface) of the back plate 57, and a pair of holder-side second engaging portions 71 project from the outer surface of the side plate 59. Yes. Two magnets 73 and three rubber parts 75 are attached to the back surface of the back plate 57. Two magnets 73 are arranged one on each side of the mounting region of the fixing plate 39 (the region covering the first bearing portion 65 and the holder-side first engaging portion 69), and three rubber parts 75 are mounted on the mounting plate 39. One on one side of the region and two on the opposite side. The top of the rubber part 75 is slightly protruded from the surface of the magnet 73. This is because when the case holder 37 is attached to the attachment surface made of a magnetic metal plate with the magnet 73, the rubber part 75 is pressed against the attachment surface to prevent slipping.

  In addition, a stopper 77 that prevents the optical connector array case 25 attached to the case holder 37 from sliding downward is provided on the lower side of the inner side surface of the side plate 59. In addition, on the upper part of the inner side surface of the side plate 59, a slip-out preventing piece 79 for preventing the optical connector array case 25 attached to the case holder 37 from slipping out to the front side is formed. Further, a large hole 81 is formed in the back plate 57 at a position corresponding to the screw hole 55 of the fixed plate 39 so that the fixed plate 39 can be screwed to the mounting surface while the fixed plate 39 is attached to the back plate 57. .

  7A and 7B show a process of attaching the back side of the case holder 37 to the fixing plate 39. FIG. First, as shown in (A), the back side of the case holder 37 is opposed to the front surface of the fixed plate 39, and the first bearing portion 65 of the case holder 37 is mounted on the shaft portion 51 of the fixed plate 39. Then, as shown in (B), the case holder 37 is attached to the fixed plate 39 so as to be rotatable about the shaft portion 51. Thereafter, when the holder-side first engaging portion 69 (see FIG. 6) protruding from the back surface of the case holder 37 is engaged with the fixed plate-side engaging portion 53 of the fixed plate 39, the case holder 37 is freely rotated. Is restricted and temporarily fixed.

  When the side surface side of the case holder 37 is attached to the fixed plate 39, the second bearing portion 67 of the case holder 37 is attached to the shaft portion 51 of the fixed plate 39, and then the holder side that protrudes to the side surface of the case holder 37. The second engaging portion 71 may be engaged with the fixed plate side engaging portion 53 of the fixed plate 39.

  In FIG. 1, the case holder 37 is assembled to the fixing plate 39 fixed to the mounting surface 41 by screwing or the like (or the fixing plate 39 assembled to the case holder 37 as shown in FIG. The optical connector array case 25 is assembled to the case holder 37 after being fixed with a stopper or the like. The optical connector array case 25 (in FIG. 1A) has its upper right side brought into contact with the upper surface plate 61 of the case holder 37 so that the upper right side of the optical connector arrangement case 25 is inserted into the inside of the prevention piece 79. When pushed toward the back plate 57 of the case holder 37, the elastic locking piece 63 is once elastically deformed to the outside and then returns to its original state, and the locking claw 63a is hooked on the front edge of the case body 23, and further the case A stopper 77 (see FIG. 6) of the holder 37 supports a part of the lower end surface of the case body 23 and is held by the case holder 37.

  In the state of FIG. 1, since the fixing plate side engaging portion 53 of the fixing plate 39 and the holder side first engaging portion 69 of the case holder 37 are engaged, the optical connector arrangement case 25 freely rotates. It is not possible to hold it as it is. In this state, the openings of the connector adapters 19 and 21 of each optical connector are directed downward. This state is a standby state in which the attaching / detaching operation of the counterpart optical connector is not performed.

  In the state of FIG. 1, when the optical connector array case 25 is pulled strongly toward the front side, the engagement between the fixing plate side engaging portion 53 of the fixing plate 39 and the holder side first engaging portion 69 of the case holder 37 is released. (The engagement between the engaging portions 53 and 69 is such a light engagement). For this reason, as shown in FIG. 2, the optical connector arrangement case 25 rotates so that the lower part is pulled out toward the front side with the shaft portion 51 of the fixed plate 39 as the center. If it will be in this state, since the operator can confirm visually the connector adapters 19 and 21 (connection port) of each optical connector, the attachment or detachment work of the other party optical connector can be performed easily. After completion of the optical connector attaching / detaching operation, the apparatus is returned to the standby state shown in FIG. In FIG. 1 and FIG. 2, a dust-proof plug 83 is attached to the connector adapters 19 and 21. When connecting the counterpart optical connector, the plug 83 is removed and the connection work is performed.

  The mounting state of FIG. 1 does not require a large depth space, and is suitable for installing the optical connector arrangement case in a place where the depth is shallow (such as a switchboard with a small depth dimension).

  However, since the installation state of FIG. 1 requires a space larger than the front width dimension of the optical connector array case 25 in the horizontal direction, it cannot be installed when the installation space in the horizontal direction (left and right) is narrow. In that case, the side surface of the case holder 37 may be assembled to the fixed plate 39 as shown in FIG. That is, the second bearing portion 67 (see FIG. 6) of the case holder 37 is attached to the shaft portion 51 (see FIG. 5) of the fixing plate 39, and the case is attached to the fixing plate side engaging portion 53 of the fixing plate 39. The holder side second engagement portion 71 of the holder 37 is engaged. In this way, the optical connector array case 25 can be attached even when the installation space in the lateral direction is narrow, since the optical connector array case 25 is attached with its front face directed in a direction perpendicular to the attachment surface 41. FIG. 8 shows a standby state in which the attaching / detaching operation of the counterpart optical connector is not performed.

  In the state of FIG. 8, when the optical connector array case 25 is pulled strongly toward the front side, the engagement between the fixing plate side engaging portion 53 of the fixing plate 39 and the holder side second engaging portion 71 of the case holder 37 is released. . Therefore, as shown in FIG. 9, the optical connector arrangement case 25 rotates so that the lower part is pulled out toward the front side with the shaft portion 51 of the fixed plate 39 as the center. If it will be in this state, since the operator can confirm visually the connector adapters 19 and 21 (connection port) of each optical connector, the attachment or detachment work of the other party optical connector can be performed easily. After completion of the optical connector attaching / detaching operation, the apparatus is returned to the standby state shown in FIG.

  By the way, as shown in FIG. 1, in a state where the back side of the case holder 37 is assembled to the fixing plate 39, the fixing plate 39 can be fixed to the mounting surface 41 by screwing or the like. If it is configured by a plate, the case holder 37 can be attached to the attachment surface 41 by the magnet 73. In order to be able to cope with both of these attachment methods, the fixing plate side engaging portion 53 of the fixing plate 39 and the holder side first engaging portion 69 of the case holder 37 have a relationship as shown in FIG. Is formed. Rounded bulges 85 are formed inwardly at the distal ends of the pair of fixed plate side engaging portions 53, respectively, and rounded bulges are respectively formed at the distal ends of the pair of holder side first engaging portions 69. The part 87 is formed outward.

  In FIG. 10A, in order to assemble the back side of the case holder 37 to the fixed plate 39, the fixed plate side engaging portion 53 of the fixed plate 39 and the holder side first engaging portion 69 of the case holder 37 are opposed to each other. State. When the case holder 37 is moved closer to the fixing plate 39 from this state, the tip bulging portion 85 of the fixing plate side engaging portion 53 and the tip bulging portion 87 of the holder side first engaging portion 69 first come into contact with each other. When further approached, the tip bulging portion 85 of the fixed plate side engaging portion 53 and the tip bulging portion 87 of the holder side first engaging portion 69 are engaged as shown in FIG. As a result, the case holder 37 is temporarily fixed to the fixing plate 39 so that it cannot be pulled back easily, but it can be pushed in until it reaches the state (C). That is, the fixed plate side engaging portion 53 and the holder side first engaging portion 69 are provided with play so that they can reciprocate between (B) and (C) while being engaged with each other. Due to this play, the back surface of the fixing plate 39 enters the inside of the plane connecting the tops of the respective rubber parts 75 (the state shown in FIG. 10C) or goes outside (the state shown in FIG. 10B). Can be done.

  In this way, when the case holder 37 is attached to the attachment surface by the fixing plate 39, the back surface of the fixing plate 39 protrudes outside the plane connecting the tops of the rubber parts 75 as shown in FIG. The fixing plate 39 can be reliably fixed to the mounting surface regardless of the protrusion of the rubber part 75. When the case holder 37 is attached to the attachment surface with a magnet, the back surface of the fixing plate 39 is retracted inward from the plane connecting the tops of the rubber parts 75 as shown in FIG. The attachment with the magnet can be performed while being attached to the back surface of the case holder 37.

  Next, with reference to FIG. 11, a preferable shape of the shaft portion 51 of the fixing plate and the first bearing portion 65 of the case holder will be described (Here, the first bearing portion 65 will be described. The same applies to the bearing portion 67). As shown in FIG. 11, the shaft portion 51 of the fixed plate is formed in an oval cross-section (a shape composed of two flat surfaces having a parallel outer peripheral surface and two arc surfaces having the same central axis), and a bearing of the case holder 37. The portion 65 has an inner diameter corresponding to the long diameter portion of the shaft portion 51 having an oval cross section, and the long diameter portion of the shaft portion 51 having an oval cross section cannot pass through, but the short diameter portion has an opening 89 having a width that can pass therethrough. It is preferable to be formed as described above.

  FIG. 11A shows a state in which the case holder 37 is inclined so that the opening 89 faces the same direction as the parallel surface of the shaft portion 51 in order to mount the bearing portion 65 on the shaft portion 51. The bearing part 65 is moved in a direction crossing the parallel surface of the shaft part 51 to show a state where it is mounted on the shaft part 51, and (C) thereafter shows the case holder 37 so that the back surface is parallel to the mounting surface. The rotated state is shown. In the state (C), there is no possibility that the bearing portion 65 is detached from the shaft portion 51. Further, when the case holder 37 is rotated, the bearing portion 65 is not likely to come off from the shaft portion 51 unless the force for lifting the case holder 37 obliquely upward is applied in the state of (B). A rotational movement can be ensured.

  When the optical connector array case 25 is tilted as shown in FIG. 2 and the mating optical connector is attached or detached, the angle of the back surface of the optical connector array case 25 with respect to the mounting surface 41 is in the range of 30 ° to 90 ° (usually Therefore, it is necessary to prevent the first bearing portion 65 of the case holder 37 from being detached from the shaft portion 51 of the fixed plate 39 at least in this range of angles. For that purpose, when the angle of the back surface of the case holder 37 with respect to the front surface of the fixed plate 39 is 10 ° to 20 °, the bearing portion 65 and the shaft portion 51 can be attached and detached as shown in FIGS. It is preferable to make it.

  In this embodiment, the shaft portion 51 is formed on the fixed plate 39, and the first bearing portion 65 and the second bearing portion 67 are formed on the case holder 37. On the contrary, the bearing is mounted on the fixed plate. The first shaft portion and the second shaft portion may be formed on the case holder.

<Example 2> FIG.12 and FIG.13 shows the other Example of the optical connector arrangement | sequence case provided with the attachment member based on this invention. 12 and 13 correspond to FIGS. 1 and 2 of the first embodiment. This embodiment is different from the first embodiment in that the case holder is omitted and the optical connector array case 25 is directly attached to the fixing plate 39. For this reason, in the case main body 23 of the optical connector arrangement case 25, the first bearing portion 65, the second bearing portion 67, the case side first engagement portion 69, as in the case holder 37 shown in FIG. A case-side second engagement portion 71 is formed, and a magnet 73 (not shown) and a rubber part 75 are attached. The fixing plate 39 is the same as that shown in FIG.

  FIG. 12 shows a state in which the back surface of the optical connector arrangement case 25 is assembled to a fixing plate 39 fixed to the mounting surface 41 by screwing or the like. In the optical connector arrangement case 25, the first bearing portion 65 is mounted on the shaft portion 51 of the fixed plate 39, and the case side first engaging portion 69 is engaged with the fixed plate side engaging portion 53 of the fixed plate 39. Thus, it is assembled to the fixed plate 39.

  In the state of FIG. 12, since the fixing plate side engaging portion 53 of the fixing plate 39 and the case side first engaging portion 69 of the optical connector arranging case 25 are engaged, the optical connector arranging case 25 can be freely rotated. It cannot be moved and is held in the same position. In this state, the openings of the connector adapters 19 and 21 of each optical connector are directed downward. This state is a standby state in which the attaching / detaching operation of the counterpart optical connector is not performed.

  In the state of FIG. 12, when the optical connector array case 25 is pulled strongly toward the front side, the engagement between the fixing plate side engaging portion 53 of the fixing plate 39 and the case side first engaging portion 69 of the optical connector array case 25. Comes off. For this reason, as shown in FIG. 13, the optical connector arrangement case 25 rotates so that the lower part is pulled out toward the front side with the shaft portion 51 of the fixed plate 39 as the center. If it will be in this state, since the operator can confirm visually the connector adapters 19 and 21 (connection port) of each optical connector, the attachment or detachment work of the other party optical connector can be performed easily. After completion of the optical connector attaching / detaching operation, the apparatus is returned to the standby state shown in FIG. The attachment state of FIG. 12 does not require a large depth space, and is suitable for installing the optical connector array case in a shallow depth area (such as a distribution board with a small depth dimension).

  However, since the installation state of FIG. 12 requires a space that is larger than the front width of the optical connector array case 25 in the horizontal direction, it cannot be installed when the horizontal (left and right) installation space is small. In that case, as shown in FIG. 14, the side surface of the optical connector array case 25 may be assembled to the fixing plate 39. That is, the second bearing portion 67 of the optical connector arrangement case 25 is attached to the shaft portion 51 (see FIG. 5) of the fixed plate 39, and the optical connector arrangement case 25 is attached to the fixed plate side engaging portion 53 of the fixed plate 39.
