  Patent Documents 1 and 2 disclose an optical connection device in which a plurality of optical fibers are connected at different positions at an input end and an output end.

  For example, in a facility where a large number of optical communication lines are laid, such as a base station for optical communication or a data center, an optical wiring member in which a large number of optical waveguides (for example, optical fibers) are disposed is required. For example, in the shuffled optical wiring member, when optically coupling a plurality of optical waveguide groups to another plurality of optical waveguide groups, each of the plurality of optical waveguides extending from one optical waveguide group is mutually connected It is coupled to the other different optical waveguide group. In such an optical wiring member, a multicore optical connector (for example, an MT connector) is attached to the tip of an optical fiber ribbon as a plurality of optical waveguide groups for connection to an external device. Then, the proximal end of the optical fiber ribbon is fixed to a wiring portion in which a large number of optical waveguides are disposed so as to overlap with each other to realize predetermined optical coupling between the optical fiber ribbons. The tip of the optical fiber ribbon extends outside the housing accommodating the wiring portion.

  When connecting an optical wiring member having the above configuration to an external device, the optical fiber ribbon has an allowance of the length of the optical fiber ribbon with respect to the distance between the connected part (optical receptacle) of the external device and the housing of the optical wiring member. If the amount is small, it is not easy to connect the multi-fiber optical connector to the external device, excessive tension may be given to the optical fiber ribbon, and the optical fibers constituting the optical fiber ribbon may be disconnected. On the other hand, if the optical fiber ribbon has a sufficient length for the distance between the connection part of the external device and the housing of the optical wiring member, connection of the multi-fiber optical connector to the external device is easy. As a result, although the breakage of each optical fiber is suppressed, bending occurs in the surplus portion of the optical fiber ribbon, causing a problem that a large space is required so that this surplus portion does not interfere with other parts and the like. .

  The present invention has been made in view of such problems, and provides an optical wiring member capable of facilitating connection of a multi-fiber optical connector to an external device and reducing the surplus of optical fiber ribbons. The purpose is to

  In order to solve the problems described above, an optical wiring member according to an embodiment includes an internal space including a wiring portion in which a plurality of optical waveguides are wired, a casing having an opening communicating with the internal space, and one end An optical fiber ribbon disposed in the inner space, and a plurality of optical fiber ribbon attached multifiber optical connectors having a multifiber optical connector attached to the other end of the optical fiber ribbon. The plurality of optical waveguides have an aggregated end aggregated for each corresponding optical fiber ribbon cabled multifiber optical connector. The aggregated end is positioned at the edge of the wiring portion in the internal space of the housing and connected to one end of the optical fiber ribbon of the corresponding multifiber optical connector with optical fiber ribbon. The optical wiring member is further provided with a slide portion disposed between the edge of the wiring portion and the opening, fixed to the optical fiber ribbon, and slidably mounted in the longitudinal direction of the optical fiber ribbon.

  According to the optical wiring member according to the present invention, the connection of the multi-core optical connector to the external device can be facilitated, and the surplus of the optical fiber ribbon can be reduced.

Description of the embodiment of the present invention
First, the contents of the embodiment of the present invention will be listed and described. An optical wiring member according to one embodiment includes an internal space including a wiring portion in which a plurality of optical waveguides are wired, a housing having an opening communicating with the internal space, and an optical fiber tape having one end disposed in the internal space And a plurality of optical fiber taped multifiber optical connectors having a multifiber optical connector attached to the other end of the optical fiber tape. The plurality of optical waveguides have an aggregated end aggregated for each corresponding optical fiber ribbon cabled multifiber optical connector. The aggregated end is positioned at the edge of the wiring portion in the internal space of the housing and connected to one end of the optical fiber ribbon of the corresponding multifiber optical connector with optical fiber ribbon. The optical wiring member is further provided with a slide portion disposed between the edge of the wiring portion and the opening, fixed to the optical fiber ribbon, and slidably mounted in the longitudinal direction of the optical fiber ribbon.

  In this optical wiring member, the slide portion is disposed between the edge of the wiring portion and the opening of the housing. The slide portion is fixed to the optical fiber ribbon and is slidable in the longitudinal direction of the optical fiber ribbon. When the slide portion is moved to the opening side of the housing, the optical fiber ribbon extends inside the housing, while the length of the optical fiber ribbon outside the housing (in other words, the housing opening and the multicore) The distance to the optical connector is increased. Therefore, a sufficient margin can be given to the length of the optical fiber ribbon with respect to the distance between the connection part of the external device and the housing of the optical wiring member, and the connection of the multi-fiber optical connector to the external device Becomes easy and disconnection of each optical fiber is suppressed. In addition, when the slide part is moved to the edge of the wiring part, the optical fiber ribbon is slackened inside the housing, while the length of the optical fiber ribbon outside the housing (in other words, the housing opening and The distance to the optical fiber connector is shortened. Therefore, the surplus of the length of the optical fiber tape core with respect to the distance between the connection part of the external device and the housing of the optical wiring member is reduced, and the space for preventing the surplus from interfering with other parts etc. is reduced. can do.

  The above-mentioned optical wiring member is further provided with a first movement restricting portion which is provided between the edge of the wiring portion and the slide portion and which abuts on the slide portion to restrict movement of the slide portion toward the edge portion It is also good. Thus, it is possible to suppress the excessive bending of the optical fiber ribbon due to the slide portion sliding excessively to the edge side of the wiring portion, and to suppress the increase of the bending loss in each optical fiber. In this case, the optical wiring member may further include a first latch mechanism that locks the slide portion at a position close to the first movement restricting portion. Alternatively, the optical wiring member may further include a first suction unit that sucks the slide at a position close to the first movement restriction unit. For example, with any of these configurations, the slide portion moves to the edge of the wiring portion in a state where the multi-core optical connector is connected to the external device (that is, a state in which the bending of the optical fiber tape core is reduced) ) Can be maintained.

  The above-mentioned optical wiring member may further be provided with the 2nd movement restriction part which is provided between a slide part and an opening, contacts the slide part, and restricts the movement to the opening side of a slide part. Thereby, disconnection of each optical fiber due to the slide portion sliding excessively toward the housing opening can be suppressed. In this case, the optical wiring member may further include a second latch mechanism that locks the slide portion at a position close to the second movement restricting portion. Alternatively, the optical wiring member may further include a second suction unit that sucks the slide at a position close to the second movement restriction unit. For example, with any of these configurations, it is possible to maintain the state in which the slide portion has moved to the housing opening side, and to improve the workability when connecting the multi-fiber optical connector to the connected portion of the external device.

  The pair of side walls 15 and 16 is disposed between the bottom plate 11 and the top plate 12 side by side in the Y direction intersecting with the height direction (Z direction) and the front-rear direction (X direction). The plate 12 extends from one end to the other end in the X direction. The side walls 15, 16 respectively have inner surfaces 15a, 16a opposed to each other in the Y direction. The inner surfaces 15a and 16a of the side walls 15 and 16 extend parallel to each other and are perpendicular to the inner surfaces 11a and 12a of the bottom plate 11 and the top plate 12 and the inner surfaces 13a and 14a of the end walls 13 and 14, respectively. .

  The housing 10 has an internal space S. The internal space S is substantially defined by the inner surface 11a of the bottom plate 11 described above, the inner surface 12a of the top plate 12, the inner surfaces 13a and 14a of the end walls 13 and 14, and the inner surfaces 15a and 16a of the side walls 15 and 16, respectively. It is a rectangular space. The height in the Z direction of the internal space S is smaller than the length in the X direction and the width in the Y direction. In one example, the height in the Z direction of the internal space S is in the range of 3 mm to 50 mm, the length in the X direction is in the range of 50 mm to 500 mm, and the width in the Y direction is in the range of 50 mm to 500 mm .

  The internal space S accommodates (includes) the wiring portion S1. The end wall 13 is formed with M openings 13 b. The M openings 13 b penetrate the end wall 13 in the X direction and communicate with the internal space S from the outside of the housing 10. The M openings 13 b are formed side by side along the Y direction. The optical fiber ribbon 31 is inserted into each of the openings 13 b. That is, the tip end of the optical fiber ribbon 31 is located outside the housing 10 and the base end is located in the internal space S. Further, in the end wall 14, N openings 14 b are formed. The N openings 14 b penetrate the end wall 14 in the X direction and communicate with the internal space S from the outside of the housing 10. The N openings 14 b are formed side by side along the Y direction. An optical fiber ribbon 32 is inserted through each of the openings 14b. That is, the tip end of the optical fiber ribbon 32 is located outside the housing 10 and the base end is located in the internal space S.

  The wiring portion S1 is disposed at the center of the internal space S in the front-rear direction (X direction). That is, a predetermined distance is provided between the edge Sa on the end wall 13 side of the wiring portion S1 and the M openings 13b. A region between the edge portion Sa of the wiring portion S1 and the M openings 13b is a slack storage region S2 which can be disposed in a state in which the optical fiber ribbon 31 is slackened. Further, a predetermined distance is provided between the edge Sb on the end wall 14 side of the wiring portion S1 and the N openings 14b. An area between the edge Sb of the wiring portion S1 and the N openings 14b is a slack storage area S3 which can be disposed in a state where the optical fiber ribbon 32 is slackened. In the present embodiment, there is no partition or the like between the wiring portion S1 and the slack storage area S2, S3, but a partition or the like is arranged between the wiring portion S1 and the slack storage area S2, S3. May be

  Each of the plurality of optical waveguides (optical fibers) 20 disposed in the wiring portion S1 corresponds to one of the optical fiber ribbons 31 at one end. The plurality of optical fibers 20 have an aggregation end 23 aggregated at each of the corresponding optical fiber ribbons 31. Each of the plurality of optical fibers 20 corresponds to one of the optical fiber ribbons 32 at the other end. The plurality of optical fibers 20 have, at the other end, an aggregated end 25 aggregated for each corresponding optical fiber ribbon 32. The aggregated ends 23, 25 may be taped ends which are taped (ribbed) for the corresponding optical fiber ribbons 31, 32, respectively. In that case, the plurality of optical fibers 20 are arranged along the Y direction at the aggregation ends 23 and 25.

  In the example shown in FIG. 1, (M × N) optical fibers 20 are arranged to intersect each other in three dimensions in the wiring portion S1. The optical fiber 20 forms M concentration ends 23 in which N optical fibers 20 are collected for each corresponding optical fiber tape core wire 31 at each one end side. Further, the optical fiber 20 forms, at each of the other end sides, N aggregated end portions 25 in which M optical fibers 20 are aggregated for each corresponding optical fiber tape core wire 32. At each concentration end 23, N optical fibers 20 are arranged along the Y direction. At each concentration end 25, M optical fibers 20 are arranged along the Y direction. Each of the N optical fibers 20 of each aggregation end 23 extends toward each of the N aggregation ends 25. In other words, each of the M optical fibers 20 of each aggregation end 25 extends toward each of the M aggregation ends 23. The wiring form of such an optical fiber 20 may be referred to as shuffled optical wiring.

  The wiring form of the wiring portion S1 is not limited to such shuffled optical wiring. The number of (M × N) may be different from the total number of optical fibers 20. The wiring portion S1 can have various wiring configurations between the M aggregation ends 23 and the N aggregation ends 25, and depending on the configuration, a certain aggregation end 23 and a certain aggregation end Two or more optical fibers 20 connecting the unit 25 may be taped.

  The aggregated ends 23 and 25 are positioned in the internal space S of the housing 10. In the present embodiment, the aggregation end portions 23 and 25 are positioned at the edge of the wiring portion S1. That is, the M aggregation ends 23 are positioned at the edge Sa of the wiring portion S1, and the N aggregation ends 25 are positioned at the edge Sb of the wiring portion S1. For example, the concentrated ends 23 and 25 may be fixed to the housing 10 via a fixing member that can be fixed to the housing 10, or may be fixed to the housing 10 by an adhesive or the like.

  The proximal end of each optical fiber ribbon 31 is connected to the corresponding aggregated end 23. A portion between the proximal end of each optical fiber ribbon 31 and each opening 13b is disposed in the slack storage area S2. A multi-core optical connector 41 is attached to the tip of each optical fiber ribbon 31. Each of the optical fiber ribbons 31 is taped (ribbed) with a resin (for example, an ultraviolet curable resin) in a state where N optical fibers are arranged in one direction. The arrangement direction of the optical fibers in the optical fiber ribbon 31 is the same as the arrangement direction of the optical fibers 20 at the concentration end 23. The M optical fiber ribbons 31 are arranged spaced apart from each other along the arrangement direction of the optical fibers (that is, the width direction of the optical fiber ribbon 31).

  The multicore optical connector 41 is, for example, an MT connector. The multi-core optical connector 41 collectively connects N optical fibers constituting each optical fiber ribbon 31. The multicore optical connector 41 is connected to the optical receptacle of the external device to which the optical wiring member 1A is attached.

  The proximal end of each optical fiber ribbon 32 is connected to the corresponding aggregated end 25. A portion between the proximal end of each optical fiber ribbon 32 and each opening 14b is disposed in the slack storage area S3. A multifiber optical connector 42 is attached to the tip of each optical fiber ribbon 32. Each of the optical fiber ribbons 32 is consolidated by a resin (for example, an ultraviolet curable resin) in a state where M optical fibers are arranged in one direction, and is taped (ribbed). The arrangement direction of the optical fibers in the optical fiber ribbon 32 is the same as the arrangement direction of the optical fibers 20 at the aggregation end 25. The N optical fiber ribbons 32 are arranged to be separated from each other along the arrangement direction of the optical fibers (that is, the width direction of the optical fiber ribbon 32).

  The multicore optical connector 42 is, for example, an MT connector. The multifiber optical connector 42 collectively connects the M optical fibers constituting each of the optical fiber ribbons 32. The multicore optical connector 42 is connected to an optical receptacle of an external device to which the optical wiring member 1A is attached.

  Each of the M slide portions 51 is disposed between the edge Sa of the wiring portion S1 and the corresponding opening 13b in the slack storage area S2. Each slide portion 51 is fixed to an intermediate portion of the corresponding optical fiber ribbon 31. In one example, each slide 51 grips the middle portion of the corresponding optical fiber ribbon 31. Each slide portion 51 is mounted on at least one of the bottom plate 11 and the top plate 12 so as to be slidable relative to the housing 10 in the longitudinal direction (X direction in the present embodiment) of the respective optical fiber ribbons 31. It is attached. Since each of the optical fiber ribbons 31 is fixed to the slide part 51 at a part thereof, when the slide part 51 moves in the X direction, the part of the optical fiber ribbons 31 also moves similarly. Thus, the length (lead length) of the optical fiber ribbon 31 starting from the opening 13 b is adjusted.

  Each of the N slide portions 52 is disposed between the edge Sb of the wiring portion S1 and the corresponding opening 14b in the slack storage area S3. Each slide portion 52 is fixed to an intermediate portion of the corresponding optical fiber ribbon 32. In one example, each slide 52 grips the middle portion of the corresponding optical fiber ribbon 32. Each slide portion 52 is mounted on at least one of the bottom plate 11 and the top plate 12 so as to be slidable relative to the housing 10 in the longitudinal direction (X direction in the present embodiment) of the respective optical fiber ribbons 32. It is attached. Since each of the optical fiber ribbons 32 is fixed at its part to the slide part 52, when the slide part 52 moves in the X direction, the part of the optical fiber ribbon 32 also moves. Thus, the length (lead length) of the optical fiber ribbon 32 starting from the opening 14 b is adjusted.

  The effects obtained by the optical wiring member 1A of the present embodiment having the above configuration will be described together with the problems of the conventional optical wiring member. (A) and (b) of FIG. 6 is a cross-sectional view showing the configuration of the optical wiring member 100 as a comparative example. (A) of FIG. 6 is a cross-sectional view along the XY plane, and (b) of FIG. 6 is a cross-sectional view along the XZ plane. The optical wiring member 100 has the same configuration as the optical wiring member 1A of the present embodiment except that the slack accommodation areas S2 and S3 and the slide portions 51 and 52 are not provided.

  FIGS. 7A and 7B are cross-sectional views showing how the optical wiring member 100 is attached to an external device. As shown in (a) of FIG. 7, when the optical wiring member 100 is attached to an external device, according to the distance between connected parts (optical receptacles) 61 and 62 mounted on the board 60 of the external device and the housing 10 On the other hand, if the margin of the length of the optical fiber ribbons 31 and 32 is small, the connection of the multi-fiber optical connectors 41 and 42 to the connected parts 61 and 62 is not easy. Excessive tension or local and large bending may be applied (part A in the figure), and the optical fibers constituting the optical fiber ribbons 31 and 32 may be broken. On the other hand, as shown in (b) of FIG. 7, the length of the optical fiber ribbons 31 and 32 is sufficient for the distance between the connection parts 61 and 62 mounted on the board 60 and the housing 10. If a margin is provided, the connection of the multi-core optical connectors 41 and 42 to the connected portions 61 and 62 is facilitated and the disconnection of each optical fiber is suppressed, but the surplus of the optical fiber ribbons 31 and 32 is used. Since deflection occurs (portion B in the figure), a problem arises that a large space is required so that the surplus does not interfere with other parts and the like.

  According to the optical wiring member 1A of the present embodiment, such a problem can be solved. (A) and (b) of FIG. 2 is a cross-sectional view for explaining the effect of the optical wiring member 1A, and shows the same cross section as (b) of FIG. As described above, in the optical wiring member 1A of the present embodiment, the slide portion 51 is disposed between the edge Sa of the wiring portion S1 and the opening 13b of the housing 10. The slide portion 51 is fixed to the optical fiber ribbon 31 and is slidable in the longitudinal direction of the optical fiber ribbon 31. Similarly, the slide portion 52 is disposed between the edge Sb of the wiring portion S1 and the opening 14b of the housing 10. The slide portion 52 is fixed to the optical fiber ribbon 32 and is slidable in the longitudinal direction of the optical fiber ribbon 32.

  As shown in (a) of FIG. 2, when the slide portion 51 is moved to the opening 13 b side of the housing 10, the optical fiber ribbon 31 is expanded inside the housing 10, while the light outside the housing 10 is The length of the fiber tape core wire 31 (in other words, the distance between the opening 13 b and the multi-fiber optical connector 41) becomes long. Therefore, a sufficient margin can be given to the length of the optical fiber tape core wire 31 with respect to the distance between the connection portion (optical receptacle) 61 mounted on the board 60 of the external device and the housing 10. The connection of the multi-core optical connector 41 to the connection portion 61 is facilitated, and disconnection of the optical fibers constituting the multi-core optical connector 41 is suppressed.

  Similarly, when the slide portion 52 is moved to the opening 14 b side of the housing 10, the optical fiber ribbon 32 is extended inside the housing 10, while the length of the optical fiber ribbon 32 outside the housing 10 ( In other words, the distance between the opening 14 b and the multi-fiber optical connector 42 is increased. Therefore, a sufficient margin can be given to the length of the optical fiber ribbon 32 with respect to the distance between the connected portion (optical receptacle) 62 mounted on the board 60 and the housing 10. Thus, the connection of the multicore optical connector 42 is facilitated, and disconnection of the optical fibers constituting the multicore optical connector 42 is suppressed.

  Further, as shown in FIG. 2B, when the slide portion 51 is moved to the edge Sa side of the wiring portion S1, the optical fiber ribbon 31 is slackened inside the case 10, while the outside of the case 10 is The length of the optical fiber ribbon 31 is shortened. Therefore, the surplus of the length of the optical fiber ribbon 31 with respect to the distance between the connection part 61 mounted on the board 60 of the external device and the housing 10 of the wiring part S1 material is reduced, and the surplus is reduced The space for preventing interference with parts and the like can be reduced. In addition, the optical fiber ribbon 31 which is slackened in the housing 10 is accommodated in the slack accommodation area S2.

  Similarly, when the slide portion 52 is moved to the edge Sb side of the wiring portion S1, the optical fiber ribbon 32 is slackened in the housing 10, while the length of the optical fiber ribbon 32 outside the housing 10 is It becomes short. Therefore, the surplus of the length of the optical fiber ribbon 32 with respect to the distance between the connection portion 62 mounted on the board 60 and the case 10 of the wiring portion S1 is reduced, and the surplus is made into other parts etc. Space for preventing interference can be reduced. The optical fiber ribbon cable core 32 slackened in the housing 10 is accommodated in the slack accommodation area S3.

Second Embodiment
Subsequently, an optical wiring member 1B according to a second embodiment of the present invention will be described. (A) and (b) of FIG. 3 is a cross-sectional view showing the configuration of the optical wiring member 1B according to the second embodiment. (A) and (b) of FIG. 4 and (a) and (b) of FIG. 5 are cross-sectional views showing the operation of the optical wiring member 1B. In these figures, an XYZ orthogonal coordinate system is shown for easy understanding. (A) of FIGS. 3-5 is sectional drawing in alignment with XY plane. FIGS. 3 to 5B are cross-sectional views along the XZ plane. The optical wiring member 1B of the present embodiment differs from the optical wiring member 1A according to the first embodiment described above, except that the shapes of the slide portions 51 and 52 are different and that the movement restricting portions (stoppers) 53 to 56 are provided. It has the same configuration.

  The movement restricting unit 53 is a first movement restricting unit in the present embodiment. That is, the movement restricting portion 53 is fixed to the housing 10 (for example, at least one of the bottom plate 11 and the top plate 12) between the edge portion Sa of the wiring portion S1 and the slide portion 51, as shown in FIG. As shown in b), it abuts on the slide part 51 to restrict the movement of the slide part 51 to the edge Sa side. The movement restricting portion 53 is, for example, formed of M pieces of openings through which the M optical fiber ribbons 31 are inserted, respectively, in one plate material. When at least one of the width and the height of the slide portion 51 is larger than the opening thereof, the slide portion 51 abuts on the movement restricting portion 53, and the movement to the edge Sa side is restricted.

  The movement restriction unit 54 is also a first movement restriction unit in the present embodiment. The movement restricting portion 54 is fixed to the housing 10 (for example, at least one of the bottom plate 11 and the top plate 12) between the edge Sb of the wiring portion S1 and the slide portion 52, as illustrated in (a) and (b) of FIG. As shown in FIG. 5, the slide unit 52 abuts on the slide unit 52 to limit the movement of the slide unit 52 toward the edge Sb. For example, the movement restricting portion 54 is formed by forming N openings through which the N optical fiber ribbon fibers 32 are inserted, respectively, on a single plate material. When at least one of the width and the height of the slide portion 52 is larger than the opening, the slide portion 52 abuts on the movement restricting portion 54, and the movement to the edge Sb side is restricted.

  The movement restriction unit 55 is a second movement restriction unit in the present embodiment. That is, the movement restricting portion 55 is fixed to the housing 10 (for example, at least one of the bottom plate 11 and the top plate 12) between the edge portion Sa of the wiring portion S1 and the slide portion 51, as shown in FIG. As shown in b), it abuts on the slide part 51 to restrict the movement of the slide part 51 to the opening 13 b side. The movement restricting portion 55 has, for example, one plate member formed with M openings through which the M optical fiber ribbons 31 are inserted. When at least one of the width and the height of the slide portion 51 is larger than the opening, the slide portion 51 abuts on the movement restricting portion 55, and the movement to the opening 13b side is restricted.

  The movement restriction unit 56 is also a second movement restriction unit in the present embodiment. The movement restricting portion 56 is fixed to the housing 10 (for example, at least one of the bottom plate 11 and the top plate 12) between the edge Sb of the wiring portion S1 and the slide portion 52, as illustrated in (a) and (b) of FIG. As shown in FIG. 5, the slide unit 52 abuts on the slide unit 52 to limit the movement of the slide unit 52 toward the opening 14b. The movement restricting portion 56 is formed by, for example, forming N openings through which the N optical fiber ribbons 31 are inserted into one sheet of plate material. Since at least one of the width and the height of the slide portion 52 is larger than the opening, the slide portion 52 abuts on the movement restricting portion 56, and the movement to the opening 14b side is restricted.

  The optical wiring member 1B according to the present embodiment may further include a latch mechanism that locks the slide portion 51 at a position close to the movement restricting portion 53. Similarly, the optical wiring member 1B may further include a latch mechanism that locks the slide portion 52 at a position close to the movement restricting portion 54. These latch mechanisms are the first latch mechanisms in the present embodiment. In addition, the optical wiring member 1B according to the present embodiment may further include a latch mechanism that locks the slide portion 51 at a position close to the movement restricting portion 55. Similarly, the optical wiring member 1B may further include a latch mechanism that locks the slide portion 52 at a position close to the movement restricting portion 56. These latch mechanisms are second latch mechanisms in the present embodiment.

  Alternatively, the optical wiring member 1B according to the present embodiment may further include a suction unit that suctions the slide unit 51 at a position close to the movement restricting unit 53. Similarly, the optical wiring member 1B may further include a suction unit that suctions the slide unit 52 at a position close to the movement restriction unit 54. These suction units are the first suction units in the present embodiment. In addition, the optical wiring member 1B according to the present embodiment may further include a suction unit that suctions the slide unit 51 at a position close to the movement restricting unit 55. Similarly, the optical wiring member 1B may further include a suction unit that suctions the slide unit 52 at a position close to the movement restricting unit 56. These suction units are the second suction units in the present embodiment. For example, a magnet is used as these adsorption parts.

  Since the optical wiring member 1B of the present embodiment includes the slide portions 51 and 52, the same effects as those of the first embodiment described above can be obtained. In addition, the optical wiring member 1B of the present embodiment further includes the movement restricting portions 53 and 54. As a result, excessive bending of the optical fiber ribbons 31 and 32 due to excessive sliding of the slide parts 51 and 52 toward the edge parts Sa and Sb of the wiring part S1 is suppressed, and bending loss in each optical fiber is increased. Can be reduced. In addition, the optical wiring member 1B of the present embodiment further includes the movement restricting portions 55 and 56. Thereby, disconnection of each optical fiber due to the slide parts 51 and 52 sliding excessively toward the openings 13 b and 14 b can be suppressed.

  Furthermore, as in the present embodiment, the optical wiring member 1B may further include a latch mechanism that locks the slide portions 51 and 52 at positions close to the movement restricting portions 53 and 54, respectively. Alternatively, the optical wiring member 1B may further include a suction unit that suctions the slide portions 51 and 52 at positions close to the movement restricting portions 53 and 54, respectively. For example, with any of these configurations, the slide portions 51 and 52 move to the edge portions Sa and Sb of the wiring portion S1 while the multicore optical connectors 41 and 42 are connected to the connection portions 61 and 62, respectively. It is possible to maintain the state (that is, the state in which the bending of the optical fiber ribbons 31, 32 is reduced, see FIG. 4) and prevent the slide parts 51, 52 from moving unintentionally.

  In addition, as in the present embodiment, the optical wiring member 1B may further include a latch mechanism that locks the slide portions 51 and 52 at positions close to the movement restricting portions 55 and 56, respectively. Alternatively, the optical wiring member 1B may further include a suction unit that suctions the slide portions 51 and 52 at positions close to the movement restricting portions 55 and 56, respectively. For example, with any of these configurations, it is possible to maintain the slide portions 51 and 52 moved to the openings 13 b and 14 b and prevent the slide portions 51 and 52 from unintentionally moving. Therefore, the workability at the time of connecting the multi-core optical connectors 41 and 42 to the connected parts 61 and 62 mounted on the board 60 of the external device can be improved.

  The embodiment of the present invention has been described in detail with reference to the drawings, but the specific configuration is not limited to this embodiment. For example, although the example in which the openings 13b and 14b of the housing 10 are provided to face each other has been described in the above embodiments, the present invention is not limited to this. For example, the openings 13 b and 14 b may be respectively formed on mutually orthogonal wall surfaces of the housing 10. Moreover, although the example which the optical fiber tape cores 31 and 32 mutually have the same number (M = N) was shown in said each embodiment, it is not limited to this, the number of the optical fiber tape cores 31 and 32 mutually It may be different. Furthermore, the numbers of the optical fiber ribbon 31 and the multicore optical connector 41 may be different from each other, and the numbers of the optical fiber ribbon 32 and the multicore optical connector 42 may be different from each other. The number of cores of the 42 optical fibers may be different.
